libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON.

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie.

Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm).

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm).

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio".

That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant.

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations).

When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm).

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm: don't use any symbols from jansson.h directly Some symbols in jansson.h are macros, some are regular functions, and some are inline functions. Regular functions must not be used directly, only via dlsym(). Macros must be used directly, but it is non-obvious which symbols are macros. Hence, for each json_* macro add an nm_json_* alias. Inline functions are a bit odd. If they are inlined and don't use any non-inlined symbols from libjansson, they could be used directly. However, it's non obvious whether both of the conditions are met. Hence, we reimplement them in nm-json.h. The only function of this kind is json_decref(). The point is to not use any json_* symbols directly -- except structs and typedefs. Seemingly, with this change we don't use any jansson symbols directly. However, that is not true, as macros like nm_json_object_foreach() still are implemented based on what is included from <jansson.h>. Hence, we cannot drop patching the included jansson.h header yet and still need our wrapper functions.

The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm: don't include <jansson.h> in libnm but use own variants It's error prone to include the header and trying not to use it. Don't include <jansson.h>. Instead, redefine our nm variants of everything. Note that we only redefine stuff that is in public headers (like "json_t" typedef). libjansson anyway must not change the struct layout and the like, without breaking all applications. That is because the non-opaque code from the header anyway is part of the applications that include it. Later we will add additional unit test that checks that our redefinition matches to what we had at compile time.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications.

GVariant *
libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings.

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925.

Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm).

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed.

libnm: always build libnm with JSON validation We anyway load libjansson with dlopen(), and already before it could happen that libjansson is not available. In that case, we would not crash, but simply proceed without json validation. Since libnm-core no longer uses libjansson directly, but only via "nm-glib-aux/nm-json.h", we can just always compile with that, and use it at runtime. That means, libjansson is not a build dependency for libnm anymore, so we don't need a compile time check. Note that if you build without libjansson, then JANSSON_SONAME is undefined, and loading it will still fail at runtime. So, even if we now always build with all our code enabled, it only works if you actually build with libjansson. Still, it's simpler to drop the conditional build, as the only benefit is a (minimally) smaller build.

libnm: don't use any symbols from jansson.h directly Some symbols in jansson.h are macros, some are regular functions, and some are inline functions. Regular functions must not be used directly, only via dlsym(). Macros must be used directly, but it is non-obvious which symbols are macros. Hence, for each json_* macro add an nm_json_* alias. Inline functions are a bit odd. If they are inlined and don't use any non-inlined symbols from libjansson, they could be used directly. However, it's non obvious whether both of the conditions are met. Hence, we reimplement them in nm-json.h. The only function of this kind is json_decref(). The point is to not use any json_* symbols directly -- except structs and typedefs. Seemingly, with this change we don't use any jansson symbols directly. However, that is not true, as macros like nm_json_object_foreach() still are implemented based on what is included from <jansson.h>. Hence, we cannot drop patching the included jansson.h header yet and still need our wrapper functions.

libnm: always build libnm with JSON validation We anyway load libjansson with dlopen(), and already before it could happen that libjansson is not available. In that case, we would not crash, but simply proceed without json validation. Since libnm-core no longer uses libjansson directly, but only via "nm-glib-aux/nm-json.h", we can just always compile with that, and use it at runtime. That means, libjansson is not a build dependency for libnm anymore, so we don't need a compile time check. Note that if you build without libjansson, then JANSSON_SONAME is undefined, and loading it will still fail at runtime. So, even if we now always build with all our code enabled, it only works if you actually build with libjansson. Still, it's simpler to drop the conditional build, as the only benefit is a (minimally) smaller build.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config.

libnm: don't use any symbols from jansson.h directly Some symbols in jansson.h are macros, some are regular functions, and some are inline functions. Regular functions must not be used directly, only via dlsym(). Macros must be used directly, but it is non-obvious which symbols are macros. Hence, for each json_* macro add an nm_json_* alias. Inline functions are a bit odd. If they are inlined and don't use any non-inlined symbols from libjansson, they could be used directly. However, it's non obvious whether both of the conditions are met. Hence, we reimplement them in nm-json.h. The only function of this kind is json_decref().

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie.

Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree.

libnm: always build libnm with JSON validation We anyway load libjansson with dlopen(), and already before it could happen that libjansson is not available. In that case, we would not crash, but simply proceed without json validation. Since libnm-core no longer uses libjansson directly, but only via "nm-glib-aux/nm-json.h", we can just always compile with that, and use it at runtime. That means, libjansson is not a build dependency for libnm anymore, so we don't need a compile time check. Note that if you build without libjansson, then JANSSON_SONAME is undefined, and loading it will still fail at runtime. So, even if we now always build with all our code enabled, it only works if you actually build with libjansson. Still, it's simpler to drop the conditional build, as the only benefit is a (minimally) smaller build.

Regular functions must not be used directly, only via dlsym(). Macros must be used directly, but it is non-obvious which symbols are macros. Hence, for each json_* macro add an nm_json_* alias. Inline functions are a bit odd. If they are inlined and don't use any non-inlined symbols from libjansson, they could be used directly. However, it's non obvious whether both of the conditions are met. Hence, we reimplement them in nm-json.h. The only function of this kind is json_decref(). The point is to not use any json_* symbols directly -- except structs and typedefs. Seemingly, with this change we don't use any jansson symbols directly. However, that is not true, as macros like nm_json_object_foreach() still are implemented based on what is included from <jansson.h>.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925.

Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON.

libnm/team: strict validate team settings by libnm clients not sending the JSON When parsing a NMSettingTeam/NMSettingTeamPort from GVariant, the JSON "config" is always preferred. If that field is present, all other attributes are ignored (aside from validating that the individual fields are as expected). The idea is that the JSON config anyway must contain everything that artificial properties could. In this mode, also no validation is performed and the setting is always accepted (regardless whether libnm thinks the setting verifies). When a libnm client created the setting via the artificial properties, only send them via D-Bus and exclude the JSON config. This turns on strict validation server side. Now we actually get validation of the settings: $ nmcli connection add type team team.runner-tx-hash l3 Error: Failed to add 'team' connection: team.runner: runner-tx-hash is only allowed for runners loadbalance,lacp this is obviously a change in behavior as previously all settings would have been accepted, regardless whether they made sense.

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses.

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON.

Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset.

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it.

If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version).

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed.

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON.

libnm: always build libnm with JSON validation We anyway load libjansson with dlopen(), and already before it could happen that libjansson is not available. In that case, we would not crash, but simply proceed without json validation. Since libnm-core no longer uses libjansson directly, but only via "nm-glib-aux/nm-json.h", we can just always compile with that, and use it at runtime. That means, libjansson is not a build dependency for libnm anymore, so we don't need a compile time check. Note that if you build without libjansson, then JANSSON_SONAME is undefined, and loading it will still fail at runtime. So, even if we now always build with all our code enabled, it only works if you actually build with libjansson. Still, it's simpler to drop the conditional build, as the only benefit is a (minimally) smaller build.

The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

When a libnm client created the setting via the artificial properties, only send them via D-Bus and exclude the JSON config. This turns on strict validation server side. Now we actually get validation of the settings: $ nmcli connection add type team team.runner-tx-hash l3 Error: Failed to add 'team' connection: team.runner: runner-tx-hash is only allowed for runners loadbalance,lacp this is obviously a change in behavior as previously all settings would have been accepted, regardless whether they made sense.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is.

libnm/team: strict validate team settings by libnm clients not sending the JSON When parsing a NMSettingTeam/NMSettingTeamPort from GVariant, the JSON "config" is always preferred. If that field is present, all other attributes are ignored (aside from validating that the individual fields are as expected). The idea is that the JSON config anyway must contain everything that artificial properties could. In this mode, also no validation is performed and the setting is always accepted (regardless whether libnm thinks the setting verifies). When a libnm client created the setting via the artificial properties, only send them via D-Bus and exclude the JSON config. This turns on strict validation server side. Now we actually get validation of the settings: $ nmcli connection add type team team.runner-tx-hash l3 Error: Failed to add 'team' connection: team.runner: runner-tx-hash is only allowed for runners loadbalance,lacp this is obviously a change in behavior as previously all settings would have been accepted, regardless whether they made sense.

See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore. Also, we serialize properties to JSON/GVariant depending on whether it's marked as present, and not whether the value is set to the default (_nm_team_settings_property_to_dbus()). -- While at it, sticter validate the settings. Note that if a setting is initialized from JSON, the strict validation is not not performed. That means, such a setting will always validate, regardless whether the values in JSON are invalid according to libnm. Only when using the extended properties, strict validation is turned on. Note that libnm serializes the properties to GVariant both as JSON "config" and extended properties. Since when parsing a setting from GVariant will prefer the "config" (if present), in most cases also validation is performed. Likewise, settings plugins (keyfile, ifcfg-rh) only persist the JSON config to disk. When loading a setting from file, strict validation is also not performed. The stricter validation only happens if as last operation one of the artificial properties was set, or if the setting was created from a GVariant that has no "config" field. -- This is a (another) change in behavior.

libnm/team: fix handling default values and stricter validate team config For each artifical team property we need to track whether it was explicitly set (i.e., present in JSON/GVariant or set by the user via NMSettingTeam/NMSettingTeamPort API). -- As a plus, libnm is now no longer concerned with the underling default values that teamd uses. For example, the effective default value for "notify_peers.count" depends on the selected runner. But libnm does not need to care, it only cares wheher the property is set in JSON or not. This also means that the default (e.g. as interesting to `nmcli -o con show $PROFILE`) is independent from other properties (like the runner). Also change the default value for the GObject properties of NMSettingTeam and NMSettingTeamPort to indicate the "unset" value. For most properties, the default value is a special value that is not a valid configuration itself. For some properties the default value is itself a valid value, namely, "runner.active", "runner.fast_rate", "port.sticky" and "port.prio". As far as NMTeamSetting is concerned, it distinguishes between unset value and set value (including the default value). That means, when it parses a JSON or GVariant, it will remember whether the property was present or not. When using API of NMSettingTeam/NMSettingTeamPort to set a property to the default value, it marks the property as unset. For example, setting NM_SETTING_TEAM_RUNNER_ACTIVE to TRUE (the default), means that the value will not be serialized to JSON/GVariant. For the above 4 properties (where the default value is itself a valid value) this is a limitation of libnm API, as it does not allow to explicitly set '"runner": { "active": true }'. See SET_FIELD_MODE_SET_UNLESS_DEFAULT, Note that changing the default value for properties of NMSetting is problematic, because it changes behavior for how settings are parsed from keyfile/GVariant. For team settings that's not the case, because if a JSON "config" is present, all other properties are ignore.

/*****************************************************************************/
libnm: rework team handling of JSON config Completely refactor the team/JSON handling in libnm's NMSettingTeam and NMSettingTeamPort. - team handling was added as rh#1398925. The goal is to have a more convenient way to set properties than constructing JSON. This requires libnm to implement the hard task of parsing JSON (and exposing well-understood properties) and generating JSON (based on these "artificial" properties). But not only libnm. In particular nmcli and the D-Bus API must make this "simpler" API accessible. - since NMSettingTeam and NMSettingTeamPort are conceptually the same, add "libnm-core/nm-team-utils.h" and NMTeamSetting that tries to handle the similar code side-by-sdie. The setting classes now just delegate for everything to NMTeamSetting. - Previously, there was a very fuzzy understanding of the provided JSON config. Tighten that up, when setting a JSON config it regenerates/parses all other properties and tries to make the best of it. When modifying any abstraction property, the entire JSON config gets regenerated. In particular, don't try to merge existing JSON config with the new fields. If the user uses the abstraction API, then the entire JSON gets replaced. For example note that nm_setting_team_add_link_watcher() would not be reflected in the JSON config (a bug). That only accidentally worked because client would serializing the changed link watcher to GVariant/D-Bus, then NetworkManager would set it via g_object_set(), which would renerate the JSON, and finally persist it to disk. But as far as libnm is concerned, nm_setting_team_add_link_watcher() would bring the settings instance in an inconsistent state where JSON and the link watcher property disagree. Setting any property must immediately update both the JSON and the abstraction API. - when constucting a team setting from D-Bus, we would previously parse both "config" and abstraction properties. That is wrong. Since our settings plugins only support JSON, all information must be present in the JSON config anyway. So, when "config" is present, only the JSON must be parsed. In the best case, the other information is redudant and contributes nothing. In the worse case, they information differs (which might happen if the client version differs from the server version). As the settings plugin only supports JSON, it's wrong to consider redundant, differing information from D-Bus. - we now only convert string to JSON or back when needed. Previously, setting a property resulted in parsing several JSON multiple times (per property). All operations should now scale well and be reasonably efficient. - also the property-changed signals are now handled correctly. Since NMTeamSetting knows the current state of all attributes, it can emit the exact property changed signals for what changed. - we no longer use libjansson to generate the JSON. JSON is supposed to be a machine readable exchange format, hence a major goal is to be easily handled by applications. While parsing JSON is not so trivial, writing a well-known set of values to JSON is. The advantage is that when you build libnm without libjansson support, then we still can convert the artificial properties to JSON. - Requiring libjansson in libnm is a burden, because most of the time it is not needed (as most users don't create team configurations). With this change we only require it to parse the team settings (no longer to write them). It should be reasonably simple to use a more minimalistic JSON parser that is sufficient for us, so that we can get rid of the libjansson dependency (for libnm). This also avoids the pain that we have due to the symbol collision of libjansson and libjson-glib. https://bugzilla.redhat.com/show_bug.cgi?id=1691619
