The warning was disabled in 8794164fed to avoid
false positives. But it is useful in finding errors, even if it sometimes
results in untrue warnings (c.f. 77fac974fe, da46a1bc3c).
After #19168, #19169, and #19175, there are no warnings with
-Dbuildtype=debug-optimized/-O2 and gcc-11.0.1-0.3.fc34.x86_64. Warnings
are reenabled for -O[23]
-O0 is good for development, and -O2 is the default optimization level for
Fedora package builds. -Os, -O3, -O1, and -Og still generate some warnings. In
fact, with -Os the number of warnings seems completely hopeless. Dozens and
dozens.
gcc-11.0.1-0.3.fc34.x86_64 with -Og was complaining that 'r' might be
unitialized. It cannot, but let's rework the code to use a goto instead of
conditionalizing on 'call' being unset, which I think is clearer and less error
prone. This silences the warning.
gcc-11.0.1-0.3.fc34.x86_64 was complaining that n might be unset with
--optimization=1. It was wrong, but let's rework the code to make it
obvious that it is always set.
gcc 9.3.0 "cc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0" with --optimization=1 was
not able to figure out that all cases are covered because r is either set in
the switch or type < _TABLE_DATA_TYPE_MAX.
But for a human reader this might also not be obvious: the cases are not in
exactly the same order as enum definitions, and it's a long list. By using the
goto, there should be no doubt, and we avoid checking the condition a second
time.
In b9c19bc384, I added an assert to _setfv() and
_setf(), but I forgot to do the same in _set(). Let's do this for completeness.
While at it, restructure _set() to use the same style as _setfv().
This should make it easier to remove those warnings when the compiler
gets smarter. Not sure if I got them all...
Double space before the comment start to make it easier to separate from the
preceding line.
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

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.
