4cbf560edf man/notify-selfcontained-example: check argument first
This is just good style. In this particular case, if the argument is incorrect and
the function is not tested with $NOTIFY_SOCKET set, the user could not get the
proper error until running for real.

Also, remove mention of systemd. The protocol is fully generic on purpose.

19e980eb92 man: update fedora example to F40
F40 will be out soon, so we can update the man page already. The example should
already work.

The cloud link was dropped in fd571c9df0ba86636401582c4ea0a8cb608e1216, so
drop the unused variable too.

47fba8f925 notify-example: also send STOPPING=1 at exit
I think the example should reflect the full set of lifecycle messages,
including STOPPING=1, which tells the service manager that the service
is already terminating. This is useful for reporting this information
back to the user and to suppress repeated shutdown requests.

It's not as important as the READY=1 and RELOADING=1 messages, since we
actively wait for those from the service message if the right Type= is
set. But it's still very valuable information, easy to do, and completes
the state engine.

man/kernel-command-line: be clear that resumeflags= is about timeout opts only 2024-04-03 22:08:11 +08:00

dfad86b838
units: introduce systemd-hibernate-clear.service that clears
stale HibernateLocation EFI variable

Currently, if the HibernateLocation EFI variable exists,
but we failed to resume from it, the boot carries on
without clearing the stale variable. Therefore, the subsequent
boots would still be waiting for the device timeout,
unless the variable is purged manually.

There's no point to keep trying to resume after a successful
switch-root, because the hibernation image state
would have been invalidated by then. OTOH, we don't
want to clear the variable prematurely either,
i.e. in initrd, since if the resume device is the same
as root one, the boot won't succeed and the user might
be able to try resuming again. So, let's introduce a
unit that only runs after switch-root and clears the var.

Fixes #32021

respect what's set through 'mem_sleep_default=' kernel

97df75d7bd socket: pass socket FDs to all ExecXYZ= commands but ExecStartPre=
Today listen file descriptors created by socket unit don't get passed to
commands in Exec{Start,Stop}{Pre,Post}= socket options.

This prevents ExecXYZ= commands from accessing the created socket FDs to do
any kind of system setup which involves the socket but is not covered by
existing socket unit options.

One concrete example is to insert a socket FD into a BPF map capable of
holding socket references, such as BPF sockmap/sockhash [1] or
reuseport_sockarray [2]. Or, similarly, send the file descriptor with
SCM_RIGHTS to another process, which has access to a BPF map for storing
sockets.

To unblock this use case, pass ListenXYZ= file descriptors to ExecXYZ=
commands as listen FDs [4]. As an exception, ExecStartPre= command does not
inherit any file descriptors because it gets invoked before the listen FDs
are created.

This new behavior can potentially break existing configurations. Commands
invoked from ExecXYZ= might not expect to inherit file descriptors through
sd_listen_fds protocol.

To prevent breakage, add a new socket unit parameter,
PassFileDescriptorsToExec=, to control whether ExecXYZ= programs inherit
listen FDs.

14a5217679 resolved: support reloading configuration at runtime
Drop connections and caches and reload config from files, to allow
for low-interruptions updates, and hook up to the usual SIGHUP and
ExecReload=. Mark servers and services configured directly via D-Bus
so that they can be kept around, and only the configuration file
settings are dropped and reloaded.

e8815abff6 log: Add per target log levels
For CI in mkosi, I want to configure systemd to log at debug level
to the journal, but not to the console. While we already have max
level settings for journald's forwarding settings, not every log line
goes to the journal, specifically during early boot and when units
are connected directly to the console (think systemd-firstboot), so
let's extend the log level options we already have to allow specifying
a comma separated list of values and lets allow prefixing values with
the log target they apply to to make this possible.
