iface-helper: add nm-iface-helper for dynamic configure-then-quit support When quitting, the Manager asks each device to spawn the interface helper, which persists and manages dynamic address on the interface after NetworkManager is gone. If the dynamic address cannot be maintaned, the helper quits and the interface's address may be removed when their lifetime runs out. To keep the helper as simple as possible, NetworkManager passes most of the configuration on the command-line, including some properties of the device's current state, which are necessary for the helper to maintain DHCP leases or IPv6 SLAAC addresses.

all: cleanup includes and let "nm-default.h" include "config.h" - All internal source files (except "examples", which are not internal) should include "config.h" first. As also all internal source files should include "nm-default.h", let "config.h" be included by "nm-default.h" and include "nm-default.h" as first in every source file. We already wanted to include "nm-default.h" before other headers because it might contains some fixes (like "nm-glib.h" compatibility) that is required first. - After including "nm-default.h", we optinally allow for including the corresponding header file for the source file at hand. The idea is to ensure that each header file is self contained. - Don't include "config.h" or "nm-default.h" in any header file (except "nm-sd-adapt.h"). Public headers anyway must not include these headers, and internal headers are never included after "nm-default.h", as of the first previous point. - Include all internal headers with quotes instead of angle brackets. In practice it doesn't matter, because in our public headers we must include other headers with angle brackets. As we use our public headers also to compile our interal source files, effectively the result must be the same. Still do it for consistency. - Except for <config.h> itself. Include it with angle brackets as suggested by https://www.gnu.org/software/autoconf/manual/autoconf.html#Configuration-Headers

#include "nm-default.h"
all: consistently include config.h config.h should be included from every .c file, and it should be included before any other include. Fix that. (As a side effect of how I did this, this also changes us to consistently use "config.h" rather than <config.h>. To the extent that it matters [which is not much], quotes are more correct anyway, since we're talking about a file in our own build tree, not a system include.)

systemd: split "nm-sd.h" out of "nm-sd-adapt.h" Now we have: "nm-sd.h" is a header file of NetworkManager with utilities related to systemd. It can be used anywhere freely. Also, systemd headers that are considered public API (like "sd-event.h") can be used without restrictions. When compiling the systemd sources, we always must include "nm-sd-adapt.h" as first. Similarly, systemd headers must not include "nm-sd-adapt.h", because they are either public (in which case the adapter is not needed) or they are internal (in which case they are themself included via a systemd source). Sometimes, we must internal API (like "dhcp-lease-internal.h"). In this case, we also must include "nm-sd-adapt.h".

core: add support for RFC7217 stable privacy addressing RFC7217 introduces an alternative mechanism for creating addresses during stateless IPv6 address configuration. It's supposed to create addresses whose host part stays stable in a particular network but changes when the hosts enters another network to mitigate possibility of tracking the host movement. It can be used alongside RFC 4941 privacy extensions (temporary addresses) and replaces the use of RFC 4862 interface identifiers. The address creation mode is controlld by ip6.addr_gen_mode property (ADDR_GEN_MODE in ifcfg-rh), with values of "stable-privacy" and "eui-64", defaulting to "eui-64" if unspecified. The host part of an address is computed by hashing a system-specific secret salted with various stable values that identify the connection with a secure hash algorithm: RID = F(Prefix, Net_Iface, Network_ID, DAD_Counter, secret_key) For NetworkManager we use these parameters: * F() SHA256 hash function. * Prefix This is a network part of the /64 address * Net_Iface We use the interface name (e.g. "eth0"). This ensures the address won't change with the change of interface hardware. * Network_ID We use the connection UUID here. This ensures the salt is different for wireless networks with a different SSID as suggested by RFC7217. * DAD_Counter A per-address counter that increases with each DAD failure. * secret_key We store the secret key in /var/lib/NetworkManager/secret_key. If it's shorter than 128 bits then it's rejected. If the file is not present we initialize it by fetching 256 pseudo-random bits from /dev/urandom on first use. Duplicate address detection uses IDGEN_RETRIES = 3 and does not utilize the IDGEN_DELAY delay (despite it SHOULD). This is for ease of implementation and may change in future. Neither parameter is currently configurable.

build: don't add systemd path the include search path Our internal copy of systemd should not be in the search path. Instead, let users only #include "systemd/nm-sd.h" which then includes everything from systemd that we need. We want to avoid to accidentally include anything from our systemd-copy. Any user of that should only include "nm-sd.h", which then includes everything that is needed further. For example, "src/devices/wwan/nm-modem-manager.c" has #include <systemd/nm-daemon.h> which in turn includes #include "_sd-common.h" This works all correctly before, because #include "" will first look in the directory where sd-daemon.h is. However, our mixing of external systemd library and internal copy is rather dangerous. Try to avoid it further by keeping the include paths clean.

core: prefer connection.stable-id to generate IPv6 stable privacy addresses The Network_ID for generating RFC 7217 stable privacy IPv6 addresses is by default the UUID of the connection. Alternatively, prefer "connection.stable-id" as Network_ID to generate the stable addresses. This allows to configure a set of connections that all use the same Network_ID for generating stable addresses. Note that the stable-id and the UUID do no overlap, that is two connections [connection] uuid=uuid1 stable-id= and [connection] uuid=uuid2 stable-id=uuid1 generate distinct addresses.

platform: add non-exclusive routes and drop route-manager Previously, we would add exclusive routes via netlink message flags NLM_F_CREATE | NLM_F_REPLACE for RTM_NEWROUTE. Similar to `ip route replace`. Using that form of RTM_NEWROUTE message, we could only add a certain route with a certain network/plen,metric triple once. That was already hugely inconvenient, because - when configuring routes, multiple (managed) interfaces may get conflicting routes (multihoming). Only one of the routes can be actually configured using `ip route replace`, so we need to track routes that are currently shadowed. - when configuring routes, we might replace externally configured routes on unmanaged interfaces. We should not interfere with such routes. That was worked around by having NMRouteManager (and NMDefaultRouteManager). NMRouteManager would keep a list of the routes which NetworkManager would like to configure, even if momentarily being unable to do so due to conflicting routes. This worked mostly well but was complicated. It involved bumping metrics to avoid conflicts for device routes, as we might require them for gateway routes. Drop that now. Instead, use the corresponding of `ip route append` to configure routes. This allows NetworkManager to confiure (almost) all routes that we care. Especially, it can configure all routes on a managed interface, without replacing/interfering with routes on other interfaces. Hence, NMRouteManager becomes obsolete. It practice it is a bit more complicated because: - when adding an IPv4 address, kernel will automatically create a device route for the subnet. We should avoid that by using the IFA_F_NOPREFIXROUTE flag for IPv4 addresses (still to-do). But as kernel may not support that flag for IPv4 addresses yet (and we don't require such a kernel yet), we still need functionality similar to nm_route_manager_ip4_route_register_device_route_purge_list(). This functionality is now handled via nm_platform_ip4_dev_route_blacklist_set(). - trying to configure an IPv6 route with a source address will be rejected by kernel as long as the address is tentative (see related bug rh#1457196). Preferably, NMDevice would keep the list of routes which should be configured, while kernel would have the list of what actually is configured. There is a feed-back loop where both affect each other (for example, when externally deleting a route, NMDevice must forget about it too). Previously, NMRouteManager would have the task of remembering all routes which we currently want to configure, but cannot due to conflicting routes. We get rid of that, because now we configure non-exclusive routes. We however still will need to remember IPv6 routes with a source address, that currently cannot be configured yet. Hence, we will need to keep track of routes that currently cannot be configured, but later may be. That is still not done yet, as NMRouteManager didn't handle this correctly either.

For that, pass an NMDedupMultiIndex instance to NMPlatform and NMNetns. NMNetns than passes it on to NMDevice, NMDhcpClient, NMIP4Config and NMIP6Config. So currently NMNetns is the access point to the shared NMDedupMultiIndex instance, and it gets it from it's NMPlatform instance. The NMDedupMultiIndex instance is really a singleton, we don't want multiple instances of it. However, for testing, instead of adding a singleton instance, pass the instance explicitly around.

core: track IPv4 device routes in NMIP4Config For IPv6, we create device routes when processing the RA and add it to NMIP6Config like any other route. For IPv4 we didn't do that. Instead we created the list of device routes during nm_ip4_config_commit() and passed it to nm_platform_ip_route_sync().

platform: add non-exclusive routes and drop route-manager Previously, we would add exclusive routes via netlink message flags NLM_F_CREATE | NLM_F_REPLACE for RTM_NEWROUTE. Similar to `ip route replace`. Using that form of RTM_NEWROUTE message, we could only add a certain route with a certain network/plen,metric triple once. That was already hugely inconvenient, because - when configuring routes, multiple (managed) interfaces may get conflicting routes (multihoming). Only one of the routes can be actually configured using `ip route replace`, so we need to track routes that are currently shadowed. - when configuring routes, we might replace externally configured routes on unmanaged interfaces. We should not interfere with such routes. That was worked around by having NMRouteManager (and NMDefaultRouteManager). NMRouteManager would keep a list of the routes which NetworkManager would like to configure, even if momentarily being unable to do so due to conflicting routes. This worked mostly well but was complicated. It involved bumping metrics to avoid conflicts for device routes, as we might require them for gateway routes. Drop that now. Instead, use the corresponding of `ip route append` to configure routes. This allows NetworkManager to confiure (almost) all routes that we care. Especially, it can configure all routes on a managed interface, without replacing/interfering with routes on other interfaces. Hence, NMRouteManager becomes obsolete. It practice it is a bit more complicated because: - when adding an IPv4 address, kernel will automatically create a device route for the subnet. We should avoid that by using the IFA_F_NOPREFIXROUTE flag for IPv4 addresses (still to-do). But as kernel may not support that flag for IPv4 addresses yet (and we don't require such a kernel yet), we still need functionality similar to nm_route_manager_ip4_route_register_device_route_purge_list(). This functionality is now handled via nm_platform_ip4_dev_route_blacklist_set(). - trying to configure an IPv6 route with a source address will be rejected by kernel as long as the address is tentative (see related bug rh#1457196). Preferably, NMDevice would keep the list of routes which should be configured, while kernel would have the list of what actually is configured. There is a feed-back loop where both affect each other (for example, when externally deleting a route, NMDevice must forget about it too). Previously, NMRouteManager would have the task of remembering all routes which we currently want to configure, but cannot due to conflicting routes. We get rid of that, because now we configure non-exclusive routes. We however still will need to remember IPv6 routes with a source address, that currently cannot be configured yet. Hence, we will need to keep track of routes that currently cannot be configured, but later may be. That is still not done yet, as NMRouteManager didn't handle this correctly either.

core: fix handling IPv6 device-route and use correct route metric Before commit 6698bf58bb53fb07838c52ca67293dd5352ec31c, we would rely on kernel to add the device-route for manual IPv6 routes. We broke that and now kernel would still add the device-route, however nm_platform_ip_route_sync() would delete it immediately after. That is because previously nm_platform_ip_route_sync() would ignore routes with rtm_protocol RTPRO_KERNEL. Now, it will sync and delete those too. Fix that by adding the device-route like we do it for IPv4. This also fixes an actual issue where the automatically added route always had route-metric 256. Instead, we now use the metric from ipv6.route-metric setting. Fixes: 6698bf58bb53fb07838c52ca67293dd5352ec31c

core: workaround configuring IPv6 routes with "src" (RTA_PREFSRC) Kernel does not allow to add IPv6 routes with "src", as long as the corresponding address is still tentative (related bug rh#1457196). The workaround for this is cumbersome. First, when we fail to add such a route with "pref_src", we guess that it happend due to this issue. In that case, nm_ip6_config_commit() returns the list of routes that could not be added for the moment (but hopefully can be added later). We track this list in NMDevice, and keep trying to merge the routes back into ip6_config. In order to not try indefinitely, keep track of a timestamp when we tried to add this route for the first time. Another uglyness is that pending tentative routes don't explicitly block activation. In practice they may do, because for these routes we also have an IPv6 address that is still doing DAD, so the IP configuration is still pending due to that. https://bugzilla.redhat.com/show_bug.cgi?id=1452684

core: prefer connection.stable-id to generate IPv6 stable privacy addresses The Network_ID for generating RFC 7217 stable privacy IPv6 addresses is by default the UUID of the connection. Alternatively, prefer "connection.stable-id" as Network_ID to generate the stable addresses. This allows to configure a set of connections that all use the same Network_ID for generating stable addresses. Note that the stable-id and the UUID do no overlap, that is two connections [connection] uuid=uuid1 stable-id= and [connection] uuid=uuid2 stable-id=uuid1 generate distinct addresses.

core: add support for RFC7217 stable privacy addressing RFC7217 introduces an alternative mechanism for creating addresses during stateless IPv6 address configuration. It's supposed to create addresses whose host part stays stable in a particular network but changes when the hosts enters another network to mitigate possibility of tracking the host movement. It can be used alongside RFC 4941 privacy extensions (temporary addresses) and replaces the use of RFC 4862 interface identifiers. The address creation mode is controlld by ip6.addr_gen_mode property (ADDR_GEN_MODE in ifcfg-rh), with values of "stable-privacy" and "eui-64", defaulting to "eui-64" if unspecified. The host part of an address is computed by hashing a system-specific secret salted with various stable values that identify the connection with a secure hash algorithm: RID = F(Prefix, Net_Iface, Network_ID, DAD_Counter, secret_key) For NetworkManager we use these parameters: * F() SHA256 hash function. * Prefix This is a network part of the /64 address * Net_Iface We use the interface name (e.g. "eth0"). This ensures the address won't change with the change of interface hardware. * Network_ID We use the connection UUID here. This ensures the salt is different for wireless networks with a different SSID as suggested by RFC7217. * DAD_Counter A per-address counter that increases with each DAD failure. * secret_key We store the secret key in /var/lib/NetworkManager/secret_key. If it's shorter than 128 bits then it's rejected. If the file is not present we initialize it by fetching 256 pseudo-random bits from /dev/urandom on first use. Duplicate address detection uses IDGEN_RETRIES = 3 and does not utilize the IDGEN_DELAY delay (despite it SHOULD). This is for ease of implementation and may change in future. Neither parameter is currently configurable.

core: support IPv6 duplicate address detection NMDevice detects the DAD failures by watching the removal of tentative addresses (happens for DAD of addresses with valid lifetime, typically discovered addresses) or changes to addresses with dadfailed flag (permanent addresses, typically link-local and manually configured addresses). It retries creation of link-local addresses itself and lets RDisc know about the rest so that it can decide if it's rdisc-managed address and retry with a new address. Currently NMDevice doesn't do anything useful about link-local address DAD failures -- it just fails the link-local address addition instead of just timing out, which happened before. RDisc just logs a warning and removes the address from the list. However, with RFC7217 stable privacy addresses the use of a different address and thus a recovery from DAD failures would be possible.

core: rename NMDBusManager to NMBusManager Our gdbus generated types use the same names as their corresponding "real" types, but with "NM" changed to "NMDBus". Unfortunately, that means that introspection/nmdbus-manager.c (the generated type for src/nm-manager.c) uses the same type name as the entirely unrelated src/nm-dbus-manager.c. Fix this by removing the "d" from src/nm-dbus-manager.c. (We could rename the generated type instead, but then it becomes inconsistent with all the other generated types, and we're already using it as "NMDBusManager" in libnm/nm-manager.c.)

dbus: fix emitting D-Bus NetworkManager's old-style PropertiesChange signal Before switching to gdbus (before 1.2.0), NetworkManager used dbus-glib. Most objects in the D-Bus API with properties had a signal NetworkManager-specific "PropertiesChanged" signal. Nowadays, this way of handling of property changes is deprecated for the common "PropertiesChanged" signal on the "org.freedesktop.DBus.Properties" interface. There were a few pecularities in 1.0.0 and earlier: (1) Due to the implementation with dbus-glib, a property-changed signal was emitted on *all* interfaces. For example: - a change on a NMDeviceVeth of "NMDeviceEthernet.HwAddress" would be emitted both for the interfaces "fdo.NM.Device.Ethernet" and "fdo.NM.Device.Veth". Note that NMDeviceVeth is derived from NMDeviceEthernet and there is no "HwAddress" on veth device. - a change of "NMVpnConnection.VpnState" was emitted on both interfaces "fdo.NM.VPN.Connection" and "fdo.NM.Connecion.Active". Note that NMActiveConnection is the parent type of NMVpnConnection and only the latter has a property "VpnState". (2) NMDevice's "fdo.NM.Device" interface doesn't have a "PropertiesChanged" signal. From (1) follows that all property-changes for this type were instead invoked with an interface like "fdo.NM.Device.Ethernet" (or multiple interfaces in case of NMDeviceVeth). 1.2.0 introduced gdbus, which gives us the standard "fdo.DBus.Properties" signal. However, it made the mistake of not realizing (1), thus instead of emitting the signal once for each interface, it would pick the first one in the inheritance tree. With 1.4.0, a bug from merge commit 844345e caused signals for devices to be only emitted for the interface "fdo.NM.Device.Statistics", instead of "fdo.NM.Device.Ethernet" or "fdo.NM.Device.Veth" (or both). The latter is what bgo#770629 is about and what commit 82e9439 tried to fix. However, the fix was wrong because it tried to do the theoretically correct thing of emitting the property-changed signal exactly once for the interface that actually ontains the property. In addition, it missed that NMDevice doesn't have a PropertiesChanged signal, which caused signals for "fdo.NM.Device" to get lost *sigh*. Now, restore the (broken) behavior of 1.0.0. These old-style property changed signals are anyway considered deprecated and exist solely to satisfy old clients and preserve the old API.
