We're not removing the pushed fd "again"; this is the only place
logind removes it from PID1. (And stopping the fd doesn't always
cause PID1 to remove the fd itself; it depends on the device type).
$ git grep FDNAME
logind-session-device.c: ... "FDNAME=session-", sd->session->id);
logind-session-device.c: ... "FDNAME=session", sd->session->id);
Oops.
Fixes#8343. Or at least a more minimal reproducer. Xorg still
dies when logind is restarted, but the Xorg message says this
is entirely deliberate.
(This could also be the reason I hit #8035, instead of the race
condition I originally suggested).
This PR implements the first part of RFE #8046. I.e. this allows to
write:
```
u username -:300
```
Where the uid is chosen automatically but the gid is fixed.
The nobody user/group may not synthesized by systemd.
To run tests the functionalities in such situation, this adds tests
by user/group by daemon, as it is expected to exists all environments.
"--offset" takes an optional argument; if none is specified,
stroull() will attempt to parse a NULL pointer. For example:
$ udevadm test-builtin 'blkid --offset' /sys/dev/block/8:1
Update "--offset" to require an argument; also verify that the
offset is not negative.
"-m" is specified as a short form of "--monitor" in the option struct,
but not included in getopt_long's optstring. Update the optstring
to be consistent with the option struct.
Follow-up for ba7f4ae617.
By default, we detect if the real root has a separate /usr/sbin directory, but
this can be overrides with -Dsplit-bin=true|false. The check assumes that
/usr/sbin is split if it is not a symlink, so it'll return a false negative
with some more complicated setups. But that's OK, in those cases this should be
configured explicitly.
This will copy the structure of the directories in the root file system to
$DESTDIR. If a directory is a directory in $DESTDIR but a symlink in the root
file system, this script will fail. This means that it's not possible to reuse
a $DESTDIR from between ba7f4ae61 and this patch.
CPU accounting has a too bad impact on performance to be enabled by
default. Therefore we should not delegate "cpu" for now.
OTOH since commit e0c46a7364, memory accounting
has been turned on for all units by default so it makes sense to delegate this
controller by default.
Several tests request nobody user or group. If they are badly
configured, then tests may fail.
This makes test-execute check nobody user and group are configured
correctly before running such tests.
Fixes#8276.
