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.

device: accept multiple addresses in a DHCPv6 lease When the DHCPv6 lease received from the server contains multiple addresses, dhclient generates a new BOUND event for each of them. Instead of overwriting the previous IP6 configuration for each BOUND event, we should try to detect if the new configuration belongs to the same lease and merge its addresses with the existing one in such case. This allows NetworkManager to configure multiple addresses on an interface via DHCPv6. https://bugzilla.gnome.org/show_bug.cgi?id=681764 https://bugzilla.redhat.com/show_bug.cgi?id=1244293

platform: create netlink messages directly without libnl-route-3 Instead of using libnl-route-3 library to serialize netlink messages, construct the netlink messages ourselves. This has several advantages: - Creating the netlink message ourself is actually more straight forward then having an intermediate layer between NM and the kernel. Now it is immediately clear, how a platform request translates to a netlink/kernel request. You can look at the kernel sources how a certain netlink attribute behaves, and then it's immediately clear how to set that (and vice versa). - Older libnl versions might have bugs or missing features for which we needed to workaround (often by offering a reduced/broken/untested functionality). Now we can get rid or workaround like _nl_has_capability(), check_support_libnl_extended_ifa_flags(), HAVE_LIBNL_INET6_TOKEN. Another example is a libnl bug when setting vlan ingress map which isn't even yet fixed in libnl upstream. - We no longer need libnl-route-3 at all and can drop that runtime requirement, saving some 400k. Constructing the messages ourselves also gives better performance because we don't have to create the intermediate libnl object. - In the future we will add more link-type support which is easier to support by basing directly on the plain kernel/netlink API, instead of requiring also libnl3 to expose this functionality. E.g. adding macvtap support: we already parsed macvtap properties ourselves because of missing libnl support. To *add* macvtap support, we also would have to do it ourself (or extend libnl).

platform: add self argument to platform functions Most nm_platform_*() functions operate on the platform singleton nm_platform_get(). That made sense because the NMPlatform instance was mainly to hook fake platform for testing. While the implicit argument saved some typing, I think explicit is better. Especially, because NMPlatform could become a more usable object then just a hook for testing. With this change, NMPlatform instances can be used individually, not only as a singleton instance. Before this change, the constructor of NMLinuxPlatform could not call any nm_platform_*() functions because the singleton was not yet initialized. We could only instantiate an incomplete instance, register it via nm_platform_setup(), and then complete initialization via singleton->setup(). With this change, we can create and fully initialize NMPlatform instances before/without setting them up them as singleton. Also, currently there is no clear distinction between functions that operate on the NMPlatform instance, and functions that can be used stand-alone (e.g. nm_platform_ip4_address_to_string()). The latter can not be mocked for testing. With this change, the distinction becomes obvious. That is also useful because it becomes clearer which functions make use of the platform cache and which not. Inside nm-linux-platform.c, continue the pattern that the self instance is named @platform. That makes sense because its type is NMPlatform, and not NMLinuxPlatform what we would expect from a paramter named @self. This is a major diff that causes some pain when rebasing. Try to rebase to the parent commit of this commit as a first step. Then rebase on top of this commit using merge-strategy "ours".

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.

platform: add self argument to platform functions Most nm_platform_*() functions operate on the platform singleton nm_platform_get(). That made sense because the NMPlatform instance was mainly to hook fake platform for testing. While the implicit argument saved some typing, I think explicit is better. Especially, because NMPlatform could become a more usable object then just a hook for testing. With this change, NMPlatform instances can be used individually, not only as a singleton instance. Before this change, the constructor of NMLinuxPlatform could not call any nm_platform_*() functions because the singleton was not yet initialized. We could only instantiate an incomplete instance, register it via nm_platform_setup(), and then complete initialization via singleton->setup(). With this change, we can create and fully initialize NMPlatform instances before/without setting them up them as singleton. Also, currently there is no clear distinction between functions that operate on the NMPlatform instance, and functions that can be used stand-alone (e.g. nm_platform_ip4_address_to_string()). The latter can not be mocked for testing. With this change, the distinction becomes obvious. That is also useful because it becomes clearer which functions make use of the platform cache and which not. Inside nm-linux-platform.c, continue the pattern that the self instance is named @platform. That makes sense because its type is NMPlatform, and not NMLinuxPlatform what we would expect from a paramter named @self. This is a major diff that causes some pain when rebasing.

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.

core: move D-Bus export/unexport into NMExportedObject Move D-Bus export/unexport handling into NMExportedObject and remove type-specific export/get_path methods (export paths are now specified at the class level, and NMExportedObject handles the counters for all exported types automatically). Since all exportable objects now use the same get_path() method, we can also add some helper methods to simplify get_property() implementations for object-path and object-path-array properties.
