This is useful for situations where an array of FDs is to be passed into
a child process (i.e. by passing it through safe_fork). This function
can be called in the child (before calling exec) to pack the FDs to all
be next to each-other starting from SD_LISTEN_FDS_START (i.e. 3)
During the boot process, systemd-vconsole-setup can be started when the only
allocated VC is already taken by plymouth.
This case is expected when a boot splash is displayed hence
systemd-vconsole-setup.service should not fail if it happens.
However rather than doing nothing, the sysfs utf8 flag is set before exiting
early.
This does not change anything for DHCPv4, as a DHCPv4 address is always
requested anyway. However for DHCPv6, the client may not request IA_NA
addresses by UseAddress=no, or even if it is requested, the server may
not provide any IA_NA addresses. Even in such cases, here the check is
for delegated prefixes, hence it is not necessary to check if DHCPv6
IA_NA addresses are configured.

Fixes#31349.
Though, when unit_prepare_exec() is called, the unit should always
have the cgroup runtime context 'crt'. So, I think we can insert assert().
But, for consistency with other places that call unit_get_cgroup_runtime(),
here use the simple non-NULL check for 'crt' instead of using assert().
Follow-up for 9cc545447e.
Fixes CID#1534667.
The varlink_collect_full function did not set varlink client's state
when the reply was an error. The state was stuck in "collecting-reply".
I discovered that while hacking on network varlink interface (adding a
new varlink method). The debug logs shows the process of performing the
first query which replies with an error:
varlink: Setting state idle-client
network: Sending message: {"method":"io.systemd.Network.LLDPNeighbors","parameters":{"ifindex":1},"more":true}
network: Changing state idle-client → collecting
network: Received message: {"error":"org.varlink.service.MethodNotFound","parameters":{"method":"io.systemd.Network.LLDPNeighbors"}}
network: Changing state collecting → collecting-reply
Now another varlink_collect call is being made, but
network: Connection busy.
Failed to execute varlink call: Device or resource busy
This was not caught by the tests because there were no varlink_collect
calls that resulted in error reply.
This refactors the Unit structure a bit: all cgroup-related state fields
are moved to a new structure CGroupRuntime, which is only allocated as
we realize a cgroup.
This is both a nice cleanup and should make unit structures considerably
smaller that have no cgroup associated, because never realized or
because they belong to a unit type that doesn#t have cgroups anyway.
This makes things nicely symmetric:
ExecContext → static user configuration about execution
ExecRuntime → dynamic user state of execution
CGroupContext → static user configuration about cgroups
CGroupRuntime → dynamic user state of cgroups
And each time the XyzContext is part of the unit type structures such as
Service or Slice that need it, but the runtime object is only allocated
when a unit is started.
Allows to configure bond arp_missed_max is the maximum number of arp_interval monitor cycle
for missed ARP replies. If this number is exceeded, link is reported as
down.
From readlinkat(2):
Since Linux 2.6.39, pathname can be an empty string, in which case the
call operates on the symbolic link referred to by dirfd (which should
have been obtained using open(2) with the O_PATH and O_NOFOLLOW flags).
This functionality relied on telinit being available in a different path
then the compat symlink shipped by systemd itself. This is no longer the
case for any known distro, so remove that code.

This commit adds a new way of forwarding journal messages - forwarding
over a socket.
The socket can be any of AF_INET, AF_INET6, AF_UNIUX or AF_VSOCK.
The address to connect to is retrieved from the "journald.forward_address" credential.
It can also be specified in systemd-journald's unit file with ForwardAddress=
Since we do require these basic user services, let's make
the dependency stronger. Note that logind should enqueue
start jobs for these already in user_start(), so mostly
just paranoia.
