As in 2a5fcfae02
and in 3e67e5c992
using /usr/bin/env allows bash to be looked up in PATH
rather than being hard-coded.
As with the previous changes the same arguments apply
- distributions have scripts to rewrite shebangs on installation and
they know what locations to rely on.
- For tests/compilation we should rather rely on the user to have setup
there PATH correctly.
In particular this makes testing from git easier on NixOS where do not provide
/bin/bash to improve compose-ability.
UnitStatusMessageFormats.finished_job, if present,
will be called with the same arguments as
job_get_done_status_message_format() to provide a format string
appropriate for the context
This commit replaces "Started" with "Finished" for started oneshot
units, as mentioned in the referenced issue
Closes#2458.
We're operating on known paths in root-owned directories here, so the detour
through toctou-safe methods that require /proc to be mounted is not necessary.
Should fix https://bugzilla.redhat.com/show_bug.cgi?id=1807768.
See https://bugzilla.redhat.com/show_bug.cgi?id=1807768. It turns
out that sysusers cannot query if the group exists:
Failed to check if group dnsmasq already exists: No such process
...
Failed to check if group systemd-timesync already exists: No such process
When the same command is executed later, the issue does not occur. Not sure why
the behaviour in the initial transaction is different. But let's accept all
errors that the man pages list. We check if the user/group exists before creating
anyway, so this seems pretty safe.
It fully initializes the address structure, so no need for pre-initialization,
and also returns the length of the address, so no need to recalculate using
SOCKADDR_UN_LEN().
socklen_t is unsigned, so let's not use an int for it. (It doesn't matter, but
seems cleaner and more portable to not assume anything about the type.)
It returns 32 bits, unsigned on amd64, so it's probably similar everywhere
with glibc. But let's make the code generic, without assuming specific size
or signedness.
.msg_namelen was set to a bogus value before we actually stored the path in the
the structure. sockaddr_un_set_path() returns the length, so just use that.
Fixes#14799.
As of the commit aae9a96d4b removing --follow
option in systemctl command, OUTPUT_FOLLOW has never been set anywhere. Let's
remove it.
The condition expression of the if-statement in show_journal() that refers to
OUTPUT_FOLLOW now thus evaluates always to true. Hence, the call of
sd_journal_wait() is in dead code, and the outer infinite for-loop is
meaningless, which we remove as cleanup.
There is no functional change by this commit.
When use UseRoutes=False so the DHCP request itself does not request
for Classless Static Routes option.
As a result, the DHCP server will only respond with a Router option.
In this case since we are using the UseRoutes=False option the gateway
that comes in via the router option does not get configured.
This patch fixes theis behaviour.
systemd.show-status=error is useful for the case where people care about errors
only.
If people want to have a quiet boot, they most likely don't want to see all
status output even if there is a delay in boot, so make "quiet" imply
systemd.show-status=error instead of systemd.show-status=auto.
Fixes#14976.
We would flip to status=temporary mode on the first error, and then switch back
to status=auto after the initial transaction was done. This isn't very useful,
because usually all the messages about successfully started units and not
related to the original failure. In fact, all those messages most likely cause
the information about the prime error to scroll off screen. And if the user
requested quiet boot, there's no reason to think that they care about those
success messages.
Also, when logging about dependency cycles, treat this similarly to a unit
error and show the message even if the status is "soft disabled" (before we
wouldn't show it in that case).
When we are booting with show-status=on, normally new status updates happen a
few times per second. Thus, it is reasonable to start showing the cylon eye
after 5 s, because that means a significant delay has happened. When we are
running with show-status=off or show-status=auto (and no error had occured),
the user is expecting maybe 15 to 90 seconds with no output (because that's
usually how long the whole boot takes). So we shouldn't bother the user with
information about a few seconds of delay. Let's make the timeout 25s if we are
not showing any messages.
Conversly, when we are outputting status messages, we can show the cylon eye
with a shorter delay, now that we removed the connection to enablement status.
Let's make this 2s, so users get feedback about delays more quickly.
We know if we created the file before, no need to repeat the operation. The
state in /run should always match our internal state. Since we call
manager_set_show_status() quite often internally, this saves quite a few
pointless syscalls.
We would say "Enabling" also for SHOW_STATUS_AUTO, which is actually
"soft off". So just print the exact state to make things easier to understand.
Also add a helper function to avoid repeating the enum value list.
For #14814.
In a user namespace container:
Feb 28 12:45:53 0b2420135953 systemd[1]: Starting Home Manager...
Feb 28 12:45:53 0b2420135953 systemd[21]: systemd-homed.service: Failed to set up network namespacing: Operation not permitted
Feb 28 12:45:53 0b2420135953 systemd[21]: systemd-homed.service: Failed at step NETWORK spawning /usr/lib/systemd/systemd-homed: Operation not permitted

Feb 28 12:45:53 0b2420135953 systemd[1]: Failed to start Home Manager.
We should treat this similarly to the case where network namespace are not
supported at all.

The man pages state that the '+' prefix in Exec* directives should
ignore filesystem namespacing options such as PrivateTmp. Now it does.
This is very similar to #8842, just with PrivateTmp instead of
PrivateDevices.
Without changing the SELinux label for private /dev of a service, it will take
a generic file system label:
system_u:object_r:tmpfs_t:s0
After this change it is the same as without `PrivateDevices=yes`:
system_u:object_r:device_t:s0
This helps writing SELinux policies, as the same rules for `/dev` will apply
despite any `PrivateDevices=yes` setting.
