The RT_VIA attribute is used to specify a gateway of a different
address family. It is currently used only for IPv4 routes.
[bgalvani@redhat.com: amended the commit message]
This commit adds NM_VERSION_INFO_CAPABILITY_IPV4_FORWARDING to the
VersionInfo D-Bus property, allowing clients such as nmstate to check
the NetworkManager's support of configuring per-device IPv4 sysctl
forwarding setting directly via the capabilities bitmask instead of
relying on the NetworkManager version comparisons.
The function uses symbol sd_device_get_devtype() which is currently
commented out. Therefore, NM dynamically links to the symbol from the
libsystemd shared object, which breaks on machines without systemd.
Before:
$ nm -u build/src/core/NetworkManager | grep sd_device
U sd_device_get_sysattr_value@LIBSYSTEMD_240
$
After:
$ nm -u build/src/core/NetworkManager | grep sd_device
$

Revert systemd commit 6ebbdcc0ddba ("sd-device: use
sd_device_get_sysattr_value() to read special symlinks"). In the NM
codebase sd_device_get_sysattr_value() is currently commented out
because it depends on file chase.c which is not imported. Importing
that file would require another long chain of imports. Therefore,
revert the commit.
This reverts commit 6ebbdcc0ddbacce732001823cf2be2a1d4381c60.

It is not clear whether we can actually respect this value. For example,
we should not restore the kernel's default value on deactivation or
device's state change, but it is unclear if we can ensure that we'll
still have the connection's configuration in all possible changes of
state.
Also, it is unclear if it's a desirable value that we want to support.
At this point it is mostly clear that trying to configure NM managed
devices externally always ends being dissapointing, no matter how hard
we try.
Remove this value for now, while we discuss whether it makes sense or
not, so it doesn't become stable in the new 1.54 release.
It is useful when there is an already active device and we want to
bring it down preserving the SR-IOV VFs. For example:
$ nmcli connection add type ethernet ifname eni1np1 sriov.total-vfs 2 ipv4.method disabled ipv6.method disabled
$ nmcli connection up ethernet-eni1np1
$ ip link show eni1np1
342: eni1np1: <BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/ether 6e:cf:f0:08:74:f4 brd ff:ff:ff:ff:ff:ff
vf 0 link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff, ...
vf 1 link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff, ...
$ nmcli device modify eni1np1 sriov.preserve-on-down yes
$ nmcli connection down ethernet-eni1np1
$ ip link show eni1np1
342: eni1np1: <BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
link/ether 6e:cf:f0:08:74:f4 brd ff:ff:ff:ff:ff:ff
vf 0 link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff, ...
vf 1 link/ether 00:00:00:00:00:00 brd ff:ff:ff:ff:ff:ff, ...
Add a new "sriov.preserve-on-down" property that controls whether
NetworkManager preserves the SR-IOV parameters set on the device when
the connection is deactivated, or whether it resets them to their
default value. The SR-IOV parameters are those specified in the
"sriov" setting, like the number of VFs to create, the eswitch
configuration, etc.
Even if WireGuard is supported since long time in NetworkManager, it
is still not possible to manage the list of peers via nmcli. The
reason is that in the past we wanted to introduce a special syntax
that would allow to manage the peer list more easily. However, this
requires heavy changes to the nmcli output formatting code, and so it
never happened.
Since perfection is the enemy of good, abandon the idea of a custom
handling of peers and treat them as any other composite property. The
property is named "wireguard.peers" and exposes the peers indexed by
public key, with optional attributes.
Example:
$ nmcli connection modify wg0 wireguard.peers "8Wgc1a0jJX3rQULwD5NFFLKrKQnbOnTiaNoerLneG1o= preshared-key=16uGwZvROnwyNGoW6Z3pvJB5GKbd6ncYROA/FFleLQA= allowed-ips=0.0.0.0/0 persistent-keepalive=10"
$ nmcli connection modify wg0 +wireguard.peers "fd2NSxUjkaR/Jft15+gpXU13hKSyZLoe4cp+g+feBCc= allowed-ips=192.168.40.0/24 endpoint=172.25.10.1:8888"
$ nmcli -g wireguard.peers connection show wg0
8Wgc1a0jJX3rQULwD5NFFLKrKQnbOnTiaNoerLneG1o= allowed-ips=0.0.0.0/0 persistent-keepalive=10, fd2NSxUjkaR/Jft15+gpXU13hKSyZLoe4cp+g+feBCc= allowed-ips=192.168.40.0/24 endpoint=172.25.10.1\:8888
$ nmcli connection modify wg0 -wireguard.peers 8Wgc1a0jJX3rQULwD5NFFLKrKQnbOnTiaNoerLneG1o=
$ nmcli -g wireguard.peers connection show wg0
fd2NSxUjkaR/Jft15+gpXU13hKSyZLoe4cp+g+feBCc= allowed-ips=192.168.40.0/24 endpoint=172.25.10.1\:8888
When using the netdev datapath, we wait that the tun link appears, we
call nm_device_set_ip_ifindex() (which also brings the link up) and
then we check that the link is ready, i.e. that udev has announced the
link and the MAC address is correct. After that, we schedule stage3
(ip-config).
In this, there is a race condition that occurs sometimes in NMCI test
ovs_datapath_type_netdev_with_cloned_mac. In rare conditions,
nm_device_set_ip_ifindex() bring the interface up but then ovs-vswitch
changes again the flags of the interface without IFF_UP. The result is
that the interface stays down, breaking communications.
To fix this, we need to always call nm_device_bring_up() after the tun
device is ready. The problem is that we can't do it in
_netdev_tun_link_cb() because that function is already invoked
synchronously from platform code.
Instead, simplify the handling of the netdev datapath. Every
"link-changed" event from platform is handled by
_netdev_tun_link_cb(), which always schedule a delayed function
_netdev_tun_link_cb_in_idle(). This function just assigns the
ip-ifindex to the device if missing, and starts stage3 if the link is
ready. While doing so, it also bring the interface up.

When connecting to an AP configured for WPA3 transition mode, the
connection will fail if PMF is disabled on the client due to SAE and
FT-SAE being unconditionally added to the key_mgmt variable's
parameters.
By removing the "!is_ap ||" check, SAE and FT-SAE will no longer be
selected when PMF is disabled, allowing clients to connect via
WPA2/PSK mode as per the original intent of
a0988868ba.

It appears that xsltproc is not installed there. It is generally needed
for the docs build too, so as a crude CI heuristic, don't build anywhere
that docs are disabled.
Currently, both man pages and gtk-doc HTML documentation are enabled by
the same build option. It is common for users to want to choose whether
to build HTML docs, as not everyone cares about HTML developer docs, but
manpages are intended directly for end-user consumption and should
always be available. At the very least, there should be a separate
option to disable them to avoid accidentally disabling them while trying
to disable HTML developer docs.

When building from a release tarball of NetworkManager,
`meson.add_dist_script()` has copied various prebuilt manpages into the
tarball and building them again is not really necessary. We can just
install those directly.
This means that *all* manpages could be installed even without
introspection, even though some of them can only be *built* when
introspection is enabled.
It also means that manpages can be installed even when xsltproc is not
available at build time.
This was likely added during the port to meson. It's just a multiline
string, so it has no effect in meson, and it appears to be entirely for
things which are already implemented in meson, so there's no real point
in keeping it any longer.
It's intrinsically used when building manpages, and also part of the
introspection-specific parts of the documentation build. There's no
particular guarantee either of those will actually be invoked during a
build, so don't unconditionally look it up.
This allows building with one fewer dependency in many cases.
The Open VSwitch interfaces have corresponding platform links. When an
Open VSwitch interface is created while NetworkManager is running, the
OVS factory usually sees an OVSDB entry appear first, then creates a
NMDevice. After that, when a platform link appears, the device is
already there.
Upon a (re-)start, the link might be seen first, and then things
go south. The OVS factory rejects the device, which results in Generic
device being created instead. Another device, this time of an
appropriate is created for the same link once the OVSDB entry is seen.
Needless to say, with two NMDevices for the same platform link existing,
no end of mayhem ensues (an assertion is tripped).

A device has the "external-down" unmanaged flag when:
!is-created-by-nm AND (!is-up OR (!has-address AND !is-controller))
When the "is-up" or the "has-address" conditions change, we properly update
the unmanaged flag by calling _dev_unmanaged_check_external_down() in
_dev_l3_cfg_notify_cb(PLATFORM_CHANGE_ON_IDLE).
The "is-controller" condition changes when another link indicates the
current device as controller. We currently don't update the unmanaged flag
when that happens and so it's possible that the device stays unmanaged even
if it has a port. This can be easily reproduced by running this commands:
ip link add veth0 type veth peer name veth1
ip link add vrf0 type vrf table 10
ip link set vrf0 up
ip link set veth0 master vrf0
Sometimes, the device shows as "unmanaged" instead of "connected
(externally)".
Fix this by re-evaluating the "external-down" unmanaged flags on the
controller when a port is attached or detached.

When calling to nm_device_is_available, the device types that requires a
parent like VLAN or MACVLAN checks that their parent exists.
nm_device_is_available is a function to check if the device is available
to activate a connection, so it makes sense that if the parent is not
present it can't be activated.
However, this is wrong for 2 reasons:
1. Most of they are virtual devices that might be unrealized when
checking its availability. If they're unrealized, their parent hasn't
been set yet.
2. Even if they're realized, their current parent might not be the one
that is defined in the connection that is being activated.
This is causing that unrealized devices are not being activated as ports
because nm_manager_get_best_device_for_connection thinks that they are
not available.
Get rid of these checks for the parent in the is_available callbacks.
