shared: build helper "libnm-libnm-core-{intern|aux}.la" library for libnm-core "libnm-core" implements common functionality for "NetworkManager" and "libnm". Note that clients like "nmcli" cannot access the internal API provided by "libnm-core". So, if nmcli wants to do something that is also done by "libnm-core", , "libnm", or "NetworkManager", the code would have to be duplicated. Instead, such code can be in "libnm-libnm-core-{intern|aux}.la". Note that: 0) "libnm-libnm-core-intern.la" is used by libnm-core itsself. On the other hand, "libnm-libnm-core-aux.la" is not used by libnm-core, but provides utilities on top of it. 1) they both extend "libnm-core" with utlities that are not public API of libnm itself. Maybe part of the code should one day become public API of libnm. On the other hand, this is code for which we may not want to commit to a stable interface or which we don't want to provide as part of the API. 2) "libnm-libnm-core-intern.la" is statically linked by "libnm-core" and thus directly available to "libnm" and "NetworkManager". On the other hand, "libnm-libnm-core-aux.la" may be used by "libnm" and "NetworkManager". Both libraries may be statically linked by libnm clients (like nmcli). 3) it must only use glib, libnm-glib-aux.la, and the public API of libnm-core. This is important: it must not use "libnm-core/nm-core-internal.h" nor "libnm-core/nm-utils-private.h" so the static library is usable by nmcli which couldn't access these. Note that "shared/nm-meta-setting.c" is an entirely different case, because it behaves differently depending on whether linking against "libnm-core" or the client programs. As such, this file must be compiled twice. (cherry picked from commit af07ed01c04867e281cc3982a7ab0d244d4f8e2e)

all: make MAC address randomization algorithm configurable For the per-connection settings "ethernet.cloned-mac-address" and "wifi.cloned-mac-address", and for the per-device setting "wifi.scan-rand-mac-address", we may generate MAC addresses using either the "random" or "stable" algorithm. Add new properties "generate-mac-address-mask" that allow to configure which bits of the MAC address will be scrambled. By default, the "random" and "stable" algorithms scamble all bits of the MAC address, including the OUI part and generate a locally- administered, unicast address. By specifying a MAC address mask, we can now configure to perserve parts of the current MAC address of the device. For example, setting "FF:FF:FF:00:00:00" will preserve the first 3 octects of the current MAC address. One can also explicitly specify a MAC address to use instead of the current MAC address. For example, "FF:FF:FF:00:00:00 68:F7:28:00:00:00" sets the OUI part of the MAC address to "68:F7:28" while scrambling the last 3 octects. Similarly, "02:00:00:00:00:00 00:00:00:00:00:00" will scamble all bits of the MAC address, except clearing the second-least significant bit. Thus, creating a burned-in address, globally administered. One can also supply a list of MAC addresses like "FF:FF:FF:00:00:00 68:F7:28:00:00:00 00:0C:29:00:00:00 ..." in which case a MAC address is choosen randomly. To fully scamble the MAC address one can configure "02:00:00:00:00:00 00:00:00:00:00:00 02:00:00:00:00:00". which also randomly creates either a locally or globally administered address. With this, the following macchanger options can be implemented: `macchanger --random` This is the default if no mask is configured. -> "" while is the same as: -> "00:00:00:00:00:00" -> "02:00:00:00:00:00 02:00:00:00:00:00" `macchanger --random --bia` -> "02:00:00:00:00:00 00:00:00:00:00:00" `macchanger --ending` This option cannot be fully implemented, because macchanger uses the current MAC address but also implies --bia. -> "FF:FF:FF:00:00:00" This would yields the same result only if the current MAC address is already a burned-in address too. Otherwise, it has not the same effect as --ending. -> "FF:FF:FF:00:00:00 <MAC_ADDR>" Alternatively, instead of using the current MAC address, spell the OUI part out. But again, that is not really the same as macchanger does because you explictly have to name the OUI part to use. `machanger --another` `machanger --another_any` -> "FF:FF:FF:00:00:00 <MAC_ADDR> <MAC_ADDR> ..."

all: make MAC address randomization algorithm configurable For the per-connection settings "ethernet.cloned-mac-address" and "wifi.cloned-mac-address", and for the per-device setting "wifi.scan-rand-mac-address", we may generate MAC addresses using either the "random" or "stable" algorithm. Add new properties "generate-mac-address-mask" that allow to configure which bits of the MAC address will be scrambled. By default, the "random" and "stable" algorithms scamble all bits of the MAC address, including the OUI part and generate a locally- administered, unicast address. By specifying a MAC address mask, we can now configure to perserve parts of the current MAC address of the device. For example, setting "FF:FF:FF:00:00:00" will preserve the first 3 octects of the current MAC address. One can also explicitly specify a MAC address to use instead of the current MAC address. For example, "FF:FF:FF:00:00:00 68:F7:28:00:00:00" sets the OUI part of the MAC address to "68:F7:28" while scrambling the last 3 octects. Similarly, "02:00:00:00:00:00 00:00:00:00:00:00" will scamble all bits of the MAC address, except clearing the second-least significant bit. Thus, creating a burned-in address, globally administered. One can also supply a list of MAC addresses like "FF:FF:FF:00:00:00 68:F7:28:00:00:00 00:0C:29:00:00:00 ..." in which case a MAC address is choosen randomly. To fully scamble the MAC address one can configure "02:00:00:00:00:00 00:00:00:00:00:00 02:00:00:00:00:00". which also randomly creates either a locally or globally administered address. With this, the following macchanger options can be implemented: `macchanger --random` This is the default if no mask is configured. -> "" while is the same as: -> "00:00:00:00:00:00" -> "02:00:00:00:00:00 02:00:00:00:00:00" `macchanger --random --bia` -> "02:00:00:00:00:00 00:00:00:00:00:00" `macchanger --ending` This option cannot be fully implemented, because macchanger uses the current MAC address but also implies --bia. -> "FF:FF:FF:00:00:00" This would yields the same result only if the current MAC address is already a burned-in address too. Otherwise, it has not the same effect as --ending. -> "FF:FF:FF:00:00:00 <MAC_ADDR>" Alternatively, instead of using the current MAC address, spell the OUI part out. But again, that is not really the same as macchanger does because you explictly have to name the OUI part to use. `machanger --another` `machanger --another_any` -> "FF:FF:FF:00:00:00 <MAC_ADDR> <MAC_ADDR> ..." "$(printf "FF:FF:FF:00:00:00 %s\n" "$(sed -n 's/^\([0-9a-fA-F][0-9a-fA-F]\) \([0-9a-fA-F][0-9a-fA-F]\) \([0-9a-fA-F][0-9a-fA-F]\) .*/\1:\2:\3:00:00:00/p' /usr/share/macchanger/wireless.list | xargs)")"

device: extend MAC address handling including randomization for ethernet and wifi Extend the "ethernet.cloned-mac-address" and "wifi.cloned-mac-address" settings. Instead of specifying an explicit MAC address, the additional special values "permanent", "preserve", "random", "random-bia", "stable" and "stable-bia" are supported. "permanent" means to use the permanent hardware address. Previously that was the default if no explict cloned-mac-address was set. The default is thus still "permanent", but it can be overwritten by global configuration. "preserve" means not to configure the MAC address when activating the device. That was actually the default behavior before introducing MAC address handling with commit 1b49f941a69af910b0e68530be7339e8053068e5. "random" and "random-bia" use a randomized MAC address for each connection. "stable" and "stable-bia" use a generated, stable address based on some token. The "bia" suffix says to generate a burned-in address. The stable method by default uses as token the connection UUID, but the token can be explicitly choosen via "stable:<TOKEN>" and "stable-bia:<TOKEN>". On a D-Bus level, the "cloned-mac-address" is a bytestring and thus cannot express the new forms. It is replaced by the new "assigned-mac-address" field. For the GObject property, libnm's API, nmcli, keyfile, etc. the old name "cloned-mac-address" is still used. Deprecating the old field seems more complicated then just extending the use of the existing "cloned-mac-address" field, although the name doesn't match well with the extended meaning. There is some overlap with the "wifi.mac-address-randomization" setting. https://bugzilla.gnome.org/show_bug.cgi?id=705545 https://bugzilla.gnome.org/show_bug.cgi?id=708820 https://bugzilla.gnome.org/show_bug.cgi?id=758301

all: make MAC address randomization algorithm configurable For the per-connection settings "ethernet.cloned-mac-address" and "wifi.cloned-mac-address", and for the per-device setting "wifi.scan-rand-mac-address", we may generate MAC addresses using either the "random" or "stable" algorithm. Add new properties "generate-mac-address-mask" that allow to configure which bits of the MAC address will be scrambled. By default, the "random" and "stable" algorithms scamble all bits of the MAC address, including the OUI part and generate a locally- administered, unicast address. By specifying a MAC address mask, we can now configure to perserve parts of the current MAC address of the device. For example, setting "FF:FF:FF:00:00:00" will preserve the first 3 octects of the current MAC address. One can also explicitly specify a MAC address to use instead of the current MAC address. For example, "FF:FF:FF:00:00:00 68:F7:28:00:00:00" sets the OUI part of the MAC address to "68:F7:28" while scrambling the last 3 octects. Similarly, "02:00:00:00:00:00 00:00:00:00:00:00" will scamble all bits of the MAC address, except clearing the second-least significant bit. Thus, creating a burned-in address, globally administered. One can also supply a list of MAC addresses like "FF:FF:FF:00:00:00 68:F7:28:00:00:00 00:0C:29:00:00:00 ..." in which case a MAC address is choosen randomly. To fully scamble the MAC address one can configure "02:00:00:00:00:00 00:00:00:00:00:00 02:00:00:00:00:00". which also randomly creates either a locally or globally administered address. With this, the following macchanger options can be implemented: `macchanger --random` This is the default if no mask is configured. -> "" while is the same as: -> "00:00:00:00:00:00" -> "02:00:00:00:00:00 02:00:00:00:00:00" `macchanger --random --bia` -> "02:00:00:00:00:00 00:00:00:00:00:00" `macchanger --ending` This option cannot be fully implemented, because macchanger uses the current MAC address but also implies --bia. -> "FF:FF:FF:00:00:00" This would yields the same result only if the current MAC address is already a burned-in address too. Otherwise, it has not the same effect as --ending. -> "FF:FF:FF:00:00:00 <MAC_ADDR>" Alternatively, instead of using the current MAC address, spell the OUI part out. But again, that is not really the same as macchanger does because you explictly have to name the OUI part to use. `machanger --another` `machanger --another_any` -> "FF:FF:FF:00:00:00 <MAC_ADDR> <MAC_ADDR> ..." "$(printf "FF:FF:FF:00:00:00 %s\n" "$(sed -n 's/^\([0-9a-fA-F][0-9a-fA-F]\) \([0-9a-fA-F][0-9a-fA-F]\) \([0-9a-fA-F][0-9a-fA-F]\) .*/\1:\2:\3:00:00:00/p' /usr/share/macchanger/wireless.list | xargs)")"

libnm: rework setting metadata for property handling NMSetting internally already tracked a list of all proper GObject properties and D-Bus-only properties. Rework the tracking of the list, so that: - instead of attaching the data to the GType of the setting via g_type_set_qdata(), it is tracked in a static array indexed by NMMetaSettingType. This allows to find the setting-data by simple pointer arithmetic, instead of taking a look and iterating (like g_type_set_qdata() does). Note, that this is still thread safe, because the static table entry is initialized in the class-init function with _nm_setting_class_commit(). And it only accessed by following a NMSettingClass instance, thus the class constructor already ran (maybe not for all setting classes, but for the particular one that we look up). I think this makes initialization of the metadata simpler to understand. Previously, in a first phase each class would attach the metadata to the GType as setting_property_overrides_quark(). Then during nm_setting_class_ensure_properties() it would merge them and set as setting_properties_quark(). Now, during the first phase, we only incrementally build a properties_override GArray, which we finally hand over during nm_setting_class_commit(). - sort the property infos by name and do binary search. Also expose this meta data types as internal API in nm-setting-private.h. While not accessed yet, it can prove beneficial, to have direct (internal) access to these structures. Also, rename NMSettingProperty to NMSettInfoProperty to use a distinct naming scheme. We already have 40+ subclasses of NMSetting that are called NMSetting*. Likewise, NMMetaSetting* is heavily used already. So, choose a new, distinct name.

device: extend MAC address handling including randomization for ethernet and wifi Extend the "ethernet.cloned-mac-address" and "wifi.cloned-mac-address" settings. Instead of specifying an explicit MAC address, the additional special values "permanent", "preserve", "random", "random-bia", "stable" and "stable-bia" are supported. "permanent" means to use the permanent hardware address. Previously that was the default if no explict cloned-mac-address was set. The default is thus still "permanent", but it can be overwritten by global configuration. "preserve" means not to configure the MAC address when activating the device. That was actually the default behavior before introducing MAC address handling with commit 1b49f941a69af910b0e68530be7339e8053068e5. "random" and "random-bia" use a randomized MAC address for each connection. "stable" and "stable-bia" use a generated, stable address based on some token. The "bia" suffix says to generate a burned-in address. The stable method by default uses as token the connection UUID, but the token can be explicitly choosen via "stable:<TOKEN>" and "stable-bia:<TOKEN>". On a D-Bus level, the "cloned-mac-address" is a bytestring and thus cannot express the new forms. It is replaced by the new "assigned-mac-address" field. For the GObject property, libnm's API, nmcli, keyfile, etc. the old name "cloned-mac-address" is still used. Deprecating the old field seems more complicated then just extending the use of the existing "cloned-mac-address" field, although the name doesn't match well with the extended meaning.

device: change default value for cloned-mac-address to "preserve" (bgo#770611) Long ago before commit 1b49f94, NetworkManager did not touch the MAC address at all. Since 0.8.2 NetworkManager would modify the MAC address, and eventually it would reset the permanent MAC address of the device. This prevents a user from externally setting the MAC address via tools like macchanger and rely on NetworkManager not to reset it to the permanent MAC address. This is considered a security regression in bgo#708820. This only changed with commit 9a354cd and 1.4.0. Since then it is possible to configure "cloned-mac-address=preserve", which instead uses the "initial" MAC address when the device activates. That also changed that the "initial" MAC address is the address which was externally configured on the device as last. In other words, the "initial" MAC address is picked up from external changes, unless it was NetworkManager itself who configured the address when activating a connection. However, in absence of an explicit configuration the default for "cloned-mac-address" is still "permanent". Meaning, the user has to explicitly configure that NetworkManager should not touch the MAC address. It makes sense to change the upstream default to "preserve". Although this is a change in behavior since 0.8.2, it seems a better default. This change has the drastic effect that all the existing connections out there with "cloned-mac-address=$(nil)" change behavior after upgrade. I think most users won't notice, because their devices have the permanent address set by default anyway. I would think that there are few users who intentionally configured "cloned-mac-address=" to have NetworkManager restore the permanent address. https://bugzilla.gnome.org/show_bug.cgi?id=770611

* "random" creates a random MAC address on each connect.
device: support dynamic "connection.stable-id" in form of text-substitution Usecase: when connecting to a public Wi-Fi with MAC address randomization ("wifi.cloned-mac-address=random") you get on every re-connect a new IP address due to the changing MAC address. "wifi.cloned-mac-address=stable" is the solution for that. But that means, every time when reconnecting to this network, the same ID will be reused. We want an ID that is stable for a while, but at a later point a new ID should e generated when revisiting the Wi-Fi network. Extend the stable-id to become dynamic and support templates/substitutions. Currently supported is "${CONNECTION}", "${BOOT}" and "${RANDOM}". Any unrecognized pattern is treated verbaim/untranslated. "$$" is treated special to allow escaping the '$' character. This allows the user to still embed verbatim '$' characters with the guarantee that future versions of NetworkManager will still generate the same ID. Of course, a user could just avoid '$' in the stable-id unless using it for dynamic substitutions. Later we might want to add more recognized substitutions. For example, it could be useful to generate new IDs based on the current time. The ${} syntax is extendable to support arguments like "${PERIODIC:weekly}". Also allow "connection.stable-id" to be set as global default value. Previously that made no sense because the stable-id was static and is anyway strongly tied to the identity of the connection profile. Now, with dynamic stable-ids it gets much more useful to specify a global default. Note that pre-existing stable-ids don't change and still generate the same addresses -- unless they contain one of the new ${} patterns.

For example, setting "FF:FF:FF:00:00:00" will preserve the first 3 octects of the current MAC address. One can also explicitly specify a MAC address to use instead of the current MAC address. For example, "FF:FF:FF:00:00:00 68:F7:28:00:00:00" sets the OUI part of the MAC address to "68:F7:28" while scrambling the last 3 octects.

With this, the following macchanger options can be implemented: `macchanger --random` This is the default if no mask is configured. -> "" while is the same as: -> "00:00:00:00:00:00" -> "02:00:00:00:00:00 02:00:00:00:00:00" `macchanger --random --bia` -> "02:00:00:00:00:00 00:00:00:00:00:00" `macchanger --ending` This option cannot be fully implemented, because macchanger uses the current MAC address but also implies --bia. -> "FF:FF:FF:00:00:00" This would yields the same result only if the current MAC address is already a burned-in address too. Otherwise, it has not the same effect as --ending. -> "FF:FF:FF:00:00:00 <MAC_ADDR>" Alternatively, instead of using the current MAC address, spell the OUI part out. But again, that is not really the same as macchanger does because you explictly have to name the OUI part to use. `machanger --another` `machanger --another_any` -> "FF:FF:FF:00:00:00 <MAC_ADDR> <MAC_ADDR> ..." "$(printf "FF:FF:FF:00:00:00 %s\n" "$(sed -n 's/^\([0-9a-fA-F][0-9a-fA-F]\) \([0-9a-fA-F][0-9a-fA-F]\) \([0-9a-fA-F][0-9a-fA-F]\) .*/\1:\2:\3:00:00:00/p' /usr/share/macchanger/wireless.list | xargs)")"

libnm: rework setting metadata for property handling NMSetting internally already tracked a list of all proper GObject properties and D-Bus-only properties. Rework the tracking of the list, so that: - instead of attaching the data to the GType of the setting via g_type_set_qdata(), it is tracked in a static array indexed by NMMetaSettingType. This allows to find the setting-data by simple pointer arithmetic, instead of taking a look and iterating (like g_type_set_qdata() does). Note, that this is still thread safe, because the static table entry is initialized in the class-init function with _nm_setting_class_commit(). And it only accessed by following a NMSettingClass instance, thus the class constructor already ran (maybe not for all setting classes, but for the particular one that we look up). I think this makes initialization of the metadata simpler to understand. Previously, in a first phase each class would attach the metadata to the GType as setting_property_overrides_quark(). Then during nm_setting_class_ensure_properties() it would merge them and set as setting_properties_quark(). Now, during the first phase, we only incrementally build a properties_override GArray, which we finally hand over during nm_setting_class_commit(). - sort the property infos by name and do binary search. Also expose this meta data types as internal API in nm-setting-private.h. While not accessed yet, it can prove beneficial, to have direct (internal) access to these structures. Also, rename NMSettingProperty to NMSettInfoProperty to use a distinct naming scheme. We already have 40+ subclasses of NMSetting that are called NMSetting*. Likewise, NMMetaSetting* is heavily used already. So, choose a new, distinct name.
