This effectively reverts 5971cb9de9 and
2b00a4e03d.
Usually, it is not necessary to assign addresses to bridge slaves,
but such functionality is supported by kernel. If users explicitly
request such configuration, networkd should support that.
User instance of systemd is optional feature and if user@.service
template is masked then administrator most likely doesn't want --user
instances of systemd for logged in users. We don't need to be verbose
about it.
This enables graphical capability for a video adapter of Parallels
virtualization platform (Parallels Desktop for Mac product) which is not
a DRM device at the moment.
This fixes GUI in Fedora 29 guest on Parallels Desktop where gdm now
strictly checks for CanGraphical property of a seat, see [1].
Should be noted that there's no in-kernel driver for Parallels video at
the moment so device matching is done by vid/pid.

With multiple iterations, I found it hard to pick out the interesting bits in
the column of text. I tried plain highlighting first, but it doesn't seem
enough. But blue/yellow makes it easy to jump to the right iteration.
This was intended to be just a refactoring, but it also fixes a minor bug:
after printing "never", we would skip subsequent expressions:
$ systemd-analyze calendar --iterations=20 @0 @1
systemd-analyze calendar --iterations=20 @0 @1
Original form: @0
Normalized form: 1970-01-01 00:00:00 UTC
Next elapse: never
(the second expression was skipped).
Fixes#5659.
Currently, if Persistent=true and the machine is off at the scheduled time of the timer unit, the timer
will be triggered immediately at the next boot even if RandomizedDelaySec= is specified.
As a result, if multiple timers meet that condition, they will be triggered at the same time and too
much CPU/IO work makes boot slow down.
With this commit, if the scheduled time of the persistent timer has already elapsed at boot,
set the time when systemd first started as the scheduled time and RandomizedDelaySec= is applied to it.
We were already using OrderedSets in the manager object, but strvs in the
configuration parsing code. Using sets gives us better scaling when many
domains are used.
In oss-fuzz #13059 the attached reproducer takes approximately 30.5 s to be
parsed. Converting to sets makes this go down to 10s. This is not _vastly_
faster, but using sets seems like a nicer approach anyway. In particular, we
avoid the quadratic de-unification operation after each addition.
After debugging the issue with gdb, I found that the following change
94ddb08 "cgtop: Still try to get CPU statistics if controller-free"
has introduced a bug, which prevents process(..) method processing
memory and io controllers when cpu_accounting_is_cheap() is true.
The obvious fix is to move this branch to be the last one, keeping
the intended behavior of the above change, without having a negative
effect on the other controllers.
Fixes#11773 [systemd-cgtop no longer shows memory (and io) usage]
The second name was used in documentation, and the first in the code that
generated the unit. 'systemd-makefs' is the name we want, for example for
consistency with the systemd-makefs executable.
In principle this breaks compatibility, but in practice this is unlikely to be
noticeable. Each instance of the unit is created by writing out a full
definition, so the template was never defined. So the name could only be used
for ordering, and there is not reason to order things against this unit from
the outside: the ordering would rather be against the final mount unit.
Fixes#11769.
The current implementation copied the *complete* header to boot_params,
thus making the kernel ignore many of the fields.
As mentioned in the code comment for the sentinel variable in
bootparam.h a bootloader should only copy the setup_header, set some
fields in boot_params and zero out anything else.
This change makes systemd-boot (mostly) compliant with the Linux Boot
Protocol and the EFI Handover Protocol described in bootparam.h and
Documentation/boot.txt to fix various issues:
- Secure boot not being detected corretly by Linux (#11717)
- tboot error message / warning on boot (#11717)
- Strange purple text color when booting in qemu with OVMF
- Hopefully even more ...
This reverts commit b4f9f2a62f.
Revert this because a) the quiet bug is fixed in linux and b)
Documentation/boot.txt says "All other fields should be zero."
adds a fully safe way how apps can pin files into /tmp temporarily, excepting them from the tmpfiles aging algorithm, based on BSD file locks on dirs we descend into
Let services use a private UTS namespace. In addition, a seccomp filter is
installed on set{host,domain}name and a ro bind mounts on
/proc/sys/kernel/{host,domain}name.
Since commit 0722b35934, the root mountpoint is
unconditionnally turned to slave which breaks units that are using explicitly
MountFlags=shared (and no other options that would implicitly require a slave
root mountpoint).
Here is a test case:
$ systemctl cat test-shared-mount-flag.service
# /etc/systemd/system/test-shared-mount-flag.service
[Service]
Type=simple
ExecStartPre=/usr/bin/mkdir -p /mnt/tmp
ExecStart=/bin/sh -c "/usr/bin/mount -t tmpfs -o size=10M none /mnt/tmp && sleep infinity"
ExecStop=-/bin/sh -c "/usr/bin/umount /mnt/tmp"
MountFlags=shared
$ systemctl start test-shared-mount-flag.service
$ findmnt /mnt/tmp
$
Mount on /mnt/tmp is not visible from the host although MountFlags=shared was
used.
This patch fixes that and turns the root mountpoint to slave when it's really
required.
