This field is like preferredLanguage, but takes a priority list of
languages instead. If an app isn't translated into a user's primary
language, it can fall back to one of the other languages in the list
thus making the app more accessible to the user.
For instance: in my experience, many Ukrainians are fluent in Russian,
often significantly better than English (especially if they are of a
generation that grew up during the USSR). Such a person might set this
new variable to ["uk_UA.UTF-8", "ru_UA.UTF-8"] so that software that
lacks Ukrainian translations will first try Russian translations before
defaulting to English.

This further restricts the charset of locales to better reflect what
locales actually look like.
This allows us to safely join locale names using the `:` character, for
instance, which cannot appear in a locale name and is used by the
`$LANGUAGE` env var
The user record should be the source of truth for the user's environment
variables, and the user should be able to override them in much the same
way that they can if they simply append the variable to their ~/.profile
For example, before $LANG would never get set to the user's preferred
language, because the service manager always ensures that $LANG is set
to something (either the localed config, or a compiled-in default). Thus
the user's preferredLanguage setting was always ignored
tilde sorts lower in the version comparison spec:
https://uapi-group.org/specifications/specs/version_format_specification/
➜ systemd git:(strip) systemd-analyze compare-versions 249\~rc1 249
249\~rc1 < 249
➜ systemd git:(strip) systemd-analyze compare-versions 249-rc1 249
249-rc1 > 249
Also update tools/meson-vcs-tag.sh to use carets instead of hyphens
for the git part of the version as carets are allowed to be part of
a version by pacman while hyphens are not and both sort higher than
a version without the git part.
cryptsetup 2.7.0 adds feature to link effective volume key in custom
kernel keyring during device activation. It can be used later to pass
linked volume key to other services.
For example: kdump enabled systems installed on LUKS2 device.
This feature allows it to store volume key linked in a kernel keyring
to the kdump reserved memory and reuse it to reactivate LUKS2 device
in case of kernel crash.
OOMPolicy in scope units is separately supported in
version v253, so I think it cannot be directly used
in the manpage with the version from the service.
fix:#30836
Given that the test involves screen(1), sending various control sequences to
resize/clear the screen, most of the logs sent from the python script were
nearly impossible to read or mixed with other messages sent to the console
hence making the debug harder when the test is run manually.
This patch introduces an option to redirect the pexpect IOs into a file (to be
used in $STATEDIR/TEST-69-SHUTDOWN/run-nspawn).
The pexpect logs are also enabled later so the boot logs are skipped since
those are already included in the journal.
Kinda sad, that interfaces like this exist in 2024. But let's deal with
it: before we access "struct btrfs_ioctl_search_header" let's copy it
out, and access it only in the aligned copy.
Fixes: #31282
The structure we copy this out is a large (unaligned) binary blob, hence
let's better use the memdup_suffix0() so that gcc doesn't make
assumption about the source being a valid string.
So glibc exposes a close_range() syscall wrapper now, but they decided
to use "unsigned" as type for the fds. Which is a bit weird, because fds
are universally understood to be "int". The kernel internally uses
"unsigned", both for close() and for close_range(), but weirdly,
userspace didn't fix that for close_range() unlike what they did for
close()... Weird.
But anyway, let's follow suit, and make our wrapper match glibc's.
Fixes#31270
The idea is simple: skip the final operation that creates or removes things
or changes the attributes, but otherwise go through the rest of the code.
This results in quite a lot of fairly repetitive conditions in the low-level
code. Another approach would be to print earlier, at a higher level, but then
we'd have less precise information about what is about to happen.
The situation is a service like
Type=notify
NotifyAccess=main
and the service uses some of the systemd helper utilities, e.g.
coredumpctl. The service process will pass NOTIFY_SOCKET to the helper
child (accidentally) and the result is a spurious notification and
the warning message:
> Jan 18 09:38:01 host systemd[1]: sdnotify.service: Got notification message from PID 13736, but reception only permitted for main PID 13549
Notification from helpers seem like an unintentional composition of the
commit c118b577fa ("coredumpctl: define main through macro") and commit
6b636c2d27 ("main-func: send main exit code to parent via sd_notify() on
exit"). The former used the handy macro for a main function, the latter
equipped any main function with the notification. (Further extended in
the commit 623a00020f ("notify: Add EXIT_STATUS field").)
Since notification from systemd utitilities are meant to extend
rudimentary exit()/wait() pair generally, they may happen to land into
service's NOTIFY_SOCKET. Tone down messages of notification that won't
match NotifyAccess=.
For the other verbs turning off JSON mode makes sense, but for "call"
not so much, after all the contents of a method call reply is JSON we
couldn't really show any other way.
Hence, when JSON output was not configured otherwise in "call", default
to the same as -j.
It exposes the varlink_collect() call we internally provide: it collects
all responses of a method call that is issued with the "more" method
call flag. It then returns the result as a single JSON array.
This reworks varlink_collect() so that it is not just a wrapper around
varlink_observe(), varlink_bind_reply() and others. It becomes a first
class operation.
This has various benefits:
1. Memory management is normalized: the reply json variant is now
tracked as part of the varlink object, and thus we do not pass
ownership to the caller. This is just like we do it for simple method
calls and removes a lot of confusion.
2. The bind reply/user data pointer can be used for user stuff, we'll
not silently override this.
3. We enforce an overall time-out operation on the whole thing, so that
this synchronous operation does no longer block forever.
Let's make sure that user's cannot DoS services for other users so
easily, and enable MaxConnectionsPerSocket= by default for all of them.
Note that this is mostly paranoia for systemd-pcrextend.socket and
systemd-sysext.socket: the socket is only accessible to root anyway,
hence the accounting shouldn#t change anything. But this is just a
safety net, in preparation that we open up some functionality of these
services sooner or later.
The setting currently puts limits on connections per IP address and
AF_UNIX CID. Let's extend it to cover AF_UNIX too, where it puts a limit
on connections per UID.
This is particularly useful for the various Accept=yes Varlink services
we now have, as it means, the number of per-user instance services
cannot grow without bounds.
As described in #30940, systemd-firstboot currently does not perform
any validation on keymap entry, allowing nonexistent keymaps to be
written to /etc/vconsole.conf. This commit adds validation checks
based on those already performed on locale entry, preventing invalid
keymaps from being set.
Closes#30940
