tilde sorts lower in the version comparison spec:

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=.
