When autoclose is set (kernel default but many distributions reverse the
setting) opening a CD-rom device causes the tray to close.
The function of blkid is to report the current state of the device and
not to change it. Hence it should use O_NONBLOCK when opening the
device to avoid closing a CD-rom tray.
blkid is used liberally in scripts so it can potentially interfere with
the user operating the CD-rom hardware.
[kzak@redhat.com: add O_NONBLOCK also to:
- wipefs
- blkid_new_probe_from_filename()
- blkid_evaluate_tag()]

(cherry picked from commit 39f5af25982d8b0244000e92a9d0e0e6557d0e17)
f5947a5e92 dropped missing.h and
replaced with the more specific headers but did not add
missing_fcntl.h in places that use O_TMPFILE. This is needed for
some older versions of glibc.
Discussed in #13743, the -.service semantic conflicts with the
existing root mount and slice names, making this feature not
uniformly extensible to all types. Change the name to be
<type>.d instead.
Updating to this format also extends the top-level dropin to
unit types.
We want users to use Wants, but we'd describe Requires first and ask users to
look for Wants instead. While at it, let's split the wall of text into sensible
paragraphs: syntax first, followed by semantics and longer description, and
finally hints and comparison to other configuration items last.
The value is obviously bogus, but didn't seem to cause problems so far.
With meson-0.52.0, it causes a hang. The number of aliases is always rather
small (usually just one or two, possibly up to a dozen in a few cases), so
even if this causes some looping, it is strange that it has such a huge impact.
But let's just remove it.
Fixes#13742.
Tested with meson-0.52.0-1.module_f31+6771+f5d842eb.noarch,
meson-0.51.1-1.fc29.noarch.
For all units that aren't timers, if it is activated by another unit,
add the triggering unit under the "TriggeredBy:" header. If a unit can
trigger other units, print the units it triggers other the "Triggers:"
header.
Fixes#13756. We were returning things that didn't make much sense:
we would always use the exit_code value as the exit code. But it sometimes
contains a exit code from the process, and sometimes the number of a signal
that was used to kill the process. We would also ignore SuccessExitStatus=
and in general whether systemd thinks the service exited successfully
(hence the issue in #13756, where systemd would return success/SIGTERM,
but we'd just look at the SIGTERM part.)
If we are doing --wait, let's always propagate the exit code/status from
the child.
While at it, make the documentation useful.
journald assumes that getsockopt(SO_PEERCRED) correctly identifies the
process on the remote end of the socket. However, this is incorrect
according to man 7 socket:
The returned credentials are those that were in effect at the
time of the call to connect(2) or socketpair(2).
This becomes a problem when a new process inherits the stdout stream
from a parent. First, log messages from the child process will
be attributed to the parent. Second, the struct ucred used by journald
becomes invalid as soon as the parent exits. Further sendmsg calls then
fail with ENOENT. Logs for the child process then vanish from the journal.
Fix this by using recvmsg on the stdout stream, and refreshing the cached
struct ucred if SCM_CREDENTIALS indicate a new process.
Fixes#13708
Chromebook keyboards have a top row which generates f1-f10 key codes but
the keys have media symbols printed on them. A simple scan code to key
code mapping to the correct media keys makes the f1-f10 inaccessible. To
properly use the keyboard a custom key code to symbol mapping in xbk is
required (a variant of the chromebook xkb model is already upstream).
Other devices have similar problems.
This commit makes it possible to specify which xkb model should be used
for a specific device by setting XKB_FIXED_MODEL.
Currently, systemctl reload command breaks ordering dependencies if it's
executed when its target service unit is in activating state.
For example, prepare A.service, B.service and C.target as follows:
# systemctl cat A.service B.service C.target
# /etc/systemd/system/A.service
[Unit]
Description=A
[Service]
Type=oneshot
ExecStart=/usr/bin/echo A1
ExecStart=/usr/bin/sleep 60
ExecStart=/usr/bin/echo A2
ExecReload=/usr/bin/echo A reloaded
RemainAfterExit=yes
# /etc/systemd/system/B.service
[Unit]
Description=B
After=A.service
[Service]
Type=oneshot
ExecStart=/usr/bin/echo B
RemainAfterExit=yes
# /etc/systemd/system/C.target
[Unit]
Description=C
Wants=A.service B.service
Start them.
# systemctl daemon-reload
# systemctl start C.target
Then, we have:
# LANG=C journalctl --no-pager -u A.service -u B.service -u C.target -b

The issue occurs not only in reload command, i.e.:
- reload
- try-restart
- reload-or-restart
- reload-or-try-restart commands
The cause of this issue is that job_type_collapse() doesn't take care of the
activating state.
Fixes: #10464
Right now the `systemd-journal-remote` service does not constrain its
resource usage (I just run out of space on my 100GB partition, for
example). This patch does not change that, but it at least makes it
possible to run something like:
journalctl --directory /var/log/journal/remote --rotate --vacuum-size=90G

not remove it completely. Allow to do that by specifying an empty
