create_fifo() was added in a2fc2f8dd3, and
would always ignore failure. The test was trying to fail in this case, but
we actually don't fail, which seems to be correct. We didn't notice before
because the test was ineffective.
To make things consistent, generally log at warning level, but don't propagate
the error. For symlinks, log at debug level, as before.
For 'e', failure is not propagated now. The test is adjusted to match.
I think warning is appropriate in most cases: we do not expect a device node to
be replaced by a different device node or even a non-device file. This would
most likely be an error somewhere. An exception is made for symlinks, which are
mismatched on purpose, for example /etc/resolv.conf. With this patch, we don't
get any warnings with the any of the 74 tmpfiles.d files, which suggests that
increasing the warning levels will not cause too many unexpected warnings. If
it turns out that there are valid cases where people have expected mismatches
for non-symlink types, we can always decrease the log levels again.
"! test ..." does not cause the script to fail, even with set -e.
IIUC, bash treats this command as part of an expression line, as it
would if 'test ... && ...' was used. Failing expression lines do not
terminate the script.
This fixes the obvious cases by changing '! test' → 'test !'.
Then the inversion happens internally in test and bash will propagate
the failure.
Append 'package' and 'packageVersion' to the journal as discrete fields
COREDUMP_PKGMETA_PACKAGE and COREDUMP_PKGMETA_PACKAGEVERSION respectively,
and the full json blurb as COREDUMP_PKGMETA_JSON.
We forgot a call to dlopen_tpm2() in the unseal codepaths. As long as
automatic TPM2 device discovery was used that didn't matter, since in
that codepaths we'd have another call dlopen_tpm2(). But with an
explicitly configured TPM2 device things should work too, hence add the
missing call.
Fixes: #19206
Let's ensure our key sizes calculations are correct.
This doesn't actually change anything, just adds more safety checks.
Inspired by #19203, but not a fix.
The words and cword variables are not localized in all Bash completion
scripts that call _init_completion.
cur, prev, words, and cword (and split if using the -s flag) are all
variables that should be localized in Bash completion scripts before
calling _init_completion (even if they don't otherwise appear in the
calling script). This is done for cur and prev, but not for words and
cword. Letting words and cword remain unlocalized may clobber variables
the user is using for other purposes, which is bad.
This issue can be resolved by declaring words and cword as local
variables.
Resolves#19188.
Single-param LoadCredential= in units causes systemd v247/v248 to
assert when parsing. Disable it for now, until the fix is merged
in the stable trees, released and available (eg: in Debian
for the CI)

In some instances, particularly with swap on zram, swap used will be high
while there is still a lot of memory available. FB OOMD handles this by
thresholding kills to X% of total swap usage. Let's do the same thing here.
Anecdotally with these thresholds and my laptop which is exclusively swap
on zram I can sit at 0K / 4G swap free with most of memory free and
systemd-oomd doesn't kill anything.
Partially addresses aggressive kill behavior from
https://bugzilla.redhat.com/show_bug.cgi?id=1941170
The s390 PCI driver assigns the hotplug slot name from the
function_id attribute of the PCI device using a 8 char hexadecimal
format to match the underlying firmware/hypervisor notation.
Further, there's always a one-to-one mapping between a PCI
function and a hotplug slot, as individual functions can
hot plugged even for multi-function devices.
As the generic matching code will always try to parse the slot
name in /sys/bus/pci/slots as a positive decimal number, either
a wrong value might be produced for ID_NET_NAME_SLOT if
the slot name consists of decimal numbers only, or none at all
if a character in the range from 'a' to 'f' is encountered.
Additionally, the generic code assumes that two interfaces
share a hotplug slot, if they differ only in the function part
of the PCI address. E.g., for an interface with the PCI address
dddd:bb:aa.f, it will match the device to the first slot with
an address dddd:bb:aa. As more than one slot may have this address
for the s390 PCI driver, the wrong slot may be selected.
To resolve this we're adding a new naming schema version with the
flag NAMING_SLOT_FUNCTION_ID, which enables the correct matching
of hotplug slots if the device has an attribute named function_id.
The ID_NET_NAME_SLOT property will only be produced if there's
a file /sys/bus/pci/slots/<slotname> where <slotname> matches
the value of /sys/bus/pci/devices/.../function_id in 8 char
hex notation.

When this test is run in mkosi, the previously tested cgroup that we write
xattrs into and the root cgroup are the same.
Since the root cgroup is a live cgroup anyways (vs. the test cgroups which are
remade each time) let's generate the expected preference values from reading
the xattrs instead of assuming it will be NONE.
Since this is only changed the first time the limit is hit (and remains
set as long as the pressure remains over), I changed the name to better
reflect that.
Keeps consistent with "last_had_mem_reclaim" which is actually updated
every time there is reclaim activity.
systemd-oomd only monitors and kills within a selected cgroup subtree
For memory pressure kills, this means it's unnecessary to get the
pgscan rate across all the monitored memory pressure cgroups.
The increase will show up whether we do a total sum or not, but since
we only care about the increase in the subtree we're about to target
for a kill, we can simplify the code a bit by not doing this total sum.
One thing that came out of the test week is that systoomd needs to poll
more frequently so as not to race with the kernel oom killer in
situations where memory is eaten quickly. Memory pressure counters are
lagging so it isn't worthwhile to change the current read rate; however swap
is not lagging and can be checked more frequently.
So let's split these into 2 different timer events. As a result, swap
now also doesn't have to be subject to the post-action (post-kill) delay
that we need for memory pressure events.
Addresses some of slowness to kill discussed in
