Don't leave temporary files if the coredump service is aborted during
the operation
Yeah, these are temporary files that systemd-coredump needs while
processing the coredumps. Of course, if the coredump service is aborted
during the operation we better shouldn't leave those files around. This
is hence a bug to fix in our coredumping code.
See https://github.com/systemd/systemd/issues/2804#issuecomment-210578147
Another option is to simply use O_TMPFILE, and when it is not available
fall back to the current behaviour. After all, the files are cleaned up
eventually, through normal tmpfiles aging, and the offending file
systems are pretty exotic these days, or not in the upstream kernel.

This new feature bypasses checking if a swap partition is mounted
or if there is enough swap space available for hibernation to
succeed.
This can be useful when a system with a Solid State Disk (SSD)
has no normal swap partition or file configured, and a custom
systemd unit is used to mount a swap file just before hibernating
and unmount it just after resuming.

* man: change time unit specifier for minutes to "m", not "min".
To alert the reader to the fact that the ambiguous prefix "m" will be
interpreted as minutes, not months.
* man: change 'journal files' to 'archived journal files'.
So that the user may be reminded why they see log entries in the journal
from a time previous to the one they specified when using --vacuum-time.

Currently, 99-systemd.rules.in contains a line for network block
devices, which mark them as inactive until the first change event, and
as active from then on forward. This is not correct. A network block
device can be connected or disconnected; this state is signalled by the
presence or absense of a "pid" file, which contains the PID of the
nbd client userspace process that started the connection.
Update the rules file so that it checks for the presence of that file to
decide what to set SYSTEMD_READY to.
Note that current kernels do issue a change event upon connecting the
device, but not yet upon disconnecting. While it's possible to wait
until that's been fixed, the behaviour of the rule with TEST!="pid" in
the absence of a proper uevent is exactly the same as the behaviour of
the old rule; so it should be safe to apply now.

If you reference another unit with an escaped name, the escaped characters
should remain in the extracted word. This used to work correctly prior to
commit 34f253f0.
The problem can be seen when units with escaped names are referenced.

(#3037)
It was added in 2.6.39, and causes an assertion to fail when running in mock
hosted on 2.6.32-based RHEL-6:
Assertion 'clock_gettime(map_clock_id(clock_id), &ts) == 0' failed at systemd/src/basic/time-util.c:70, function now(). Aborting.

Fixes for preset-all handling and a few related issues
|
|
|
|
Fixes #3047.
|
|
|
|
With any masked unit that would that would be enabled by presets, we'd get:
test@rawhide $ sudo systemctl preset-all
Failed to execute operation: Unit file is masked.
test@rawhide $ sudo systemctl --root=/ preset-all
Operation failed: Cannot send after transport endpoint shutdown
Simply ignore those units:
test@rawhide $ sudo systemctl preset-all
Unit xxx.service is masked, ignoring.
|
|
If the error code ever leaks (we print the strerror error instead of providing
our own), the message for ESHUTDOWN is "Cannot send after transport endpoint
shutdown", which can be misleading. In particular it suggest that some
mishandling of the dbus connection occured. Let's change that to ERFKILL which
has the advantage that a) it sounds implausible as actual error, b) has the
connotation of disabling something manually.
|
|
The comments and the log messages are next to one another, so it's easier
to check that the messages match the comments.
The sign was omitted in the check for -ESHUTDOWN, so it was never matched.
|
|
|
|
Before 0f03c2a4c093 specifying any path would cause the systemctl client
to do the installation itself, instead of going over dbus. Restore that
behaviour.
|
|
daemons, which wish to transition state from the initramfs to the real
root, might use /dev/shm for their state.
As /dev is not relabeled across mount points, /dev/shm has to be
relabled explicitly.

build-sys: add missing -ldl

sd-bus: query pid also when requesting supplementary gids information
|
|
Code cleanups
|
|
CID #1354670.
|
|
CID #1354671: char **l would be leaked.
Also rename l to paths, to make the code easier to read,
and do strv deduplication immediately when extending. No need to allocate
strings to remove them a few lines down.
|
|
Just making sure :)

(#3023)
Fixes:
$ cd test/TEST-07-ISSUE-1981/
$ sudo make clean setup run
...
timeout: failed to run command ‘systemd-nspawn’: No such file or directory
...
TEST RUN: https://github.com/systemd/systemd/issues/1981 [FAILED]
Makefile:10: recipe for target 'run' failed

|
|
If the SD_BUS_CREDS_SUPPLEMENTARY_GIDS value is requested, the pid is
queried to find out the supplementary gids value from /proc/pid/status.
Otherwise sd_bus_creds_get_supplementary_gids() won't work unless some
other value in mask triggered fetching the pid information.
|

The coccinelle patch didn't work in some places, I have no idea why.
|

Many fixes, in particular to the install logic

Closes #1602

choke on ELOOP
ELOOP indicates that there's a symlink in /etc for a native unit file, and
that's completely OK.

Let's make this more digestable to read by making the list of documented unit
file paths a bit shorter.
Specifically, let's drop references to $XDG_CONFIG_HOME and $XDG_DATA_HOME, as
their default values are listed too already. Given that the fact that the XDG
basedir spec makes these paths configurable is probably not a strong point of
the spec, let's drop the reference to the env vars, and keep only the literal,
default paths for them in the list. Of course, we do support the full XDG
basedir spec in this regard, but it's one thing to implement it and another one
to recommend it by documenting it.
Replace "$HOME" by "~", because UNIX.
|
|
Otherwise "systemctl status" will immediately report that our unit file is out
of date.
|
|
|
|
|
|
We only use it for the Tx code anyway, hence sd-lldp.h shouldn't expose it, as
it only implements Rx.
|

be enabled
We don't allow using config symlinks to enable units, but the error message we
printed was awful. Fix that, and generate a more readable error.
Fixes #3010.

This new command removes all, or all hidden container images that have been
downloaded.

|
--enable-libmount-force-mountinfo
Fixes: #2978
|
|
This hopefully reduces confusion resulting in issues like #2992.
|
|
We don#t really support systems where XDG_RUNTIME_DIR is not supported for
systemd --user. Hence, let's always set our own XDG_RUNTIME_DIR for tests that
involve systemd --user, so that we know it is set, and that it doesn't polute
the user's actual runtime dir.
|
|
There's no point in first determining the drop-in file name path, then
forgetting it again, and then determining it again. Instead, just generated it
once, and then write to ti directly.
