I tried to use DECLARE_FLEX_ARRAY like the kernel does, but it does not work
for anonymous structs (they cannot be declared inline), so an open-coded
version is used.
The kernel was updated to not use fake flex arrays with zero size.
Updating should allow -fstrict-flex-arrays to be used.
Headers pulled from kernel-headers-6.2.0-0.rc6.git0.1.fc38.x86_64.
Note that this is not a straighforward copy: our files have local modifications
(listed in README) that need to be preserved.
Due to the limitation of `GITHUB_TOKEN` when running workflows from forks,
it's required to split the `development_freeze` workflow in two.
* First workflow will run on the `pull_request` trigger and save the PR
number in the artifact. This workflow is running with read-only permissions
on `GITHUB_TOKEN`.
* Second workflow will get triggered on `workflow_run`. It will be run
directly in the `systemd/systemd` context and can get permission to be
able to create comments on PR.

Follow-up for 64f3419ec1.
If the input timestamp is too old (say, 1min since 1970-01-01), then
parse_timestamp() may fail on a timezone with positive shift e.g.
JST (UTC+9). Moreover, even if parse_timestamp() succeeds, its result
'y' and 'usec_sub_unsigned(x, 2 * USEC_PER_DAY)' are both zero, and
the assertion will be triggered.
Fixes#26172.
The documentation on moving an existing homedir into a systemd-homed managed
one suggests using rsync(1) with a bunch of flags to preserve as much metadata
as possible: permissions, xattrs, timestamps, etc. The previously suggested
flags were:
rsync -aHAXv --remove-source-files …
… which does include mtimes, but not ctimes and atimes, because -a does not
include those:
--archive, -a archive mode is -rlptgoD (no -A,-X,-U,-N,-H)
This change adds the -N and -U flags to preserve even more file timestamps,
turning the command into:
rsync -aHANUXv --remove-source-files …
The new flags are:
--crtimes, -N preserve create times (newness)
--atimes, -U preserve access (use) times
This will be used by Tpm2Handle instances, which is added in later patches.
The refcounting allows the context to be retained until all Tpm2Handles have
been cleaned up, and the initial ref is released, before cleaning the context.
The 'pcr_bank' functions operate on hash algs, and are not specific to the PCR
banks, while the 'primary_alg' functions operate on asymmetric algs, and are
not specific to primary keys.
This gives us some nice test coverage for secure boot enrolling and the
stub secure boot workound. The authenticated EFI variables are already
created by mkosi, all we need to do is request secure boot to be used.
If any query makes it to the end of install_info_follow() then I think symlink_target is set to NULL.
If that is followed by -EXDEV from unit_file_load_or_readlink(), then that causes basename(NULL)
which segfaults pid 1.
This is triggered by eg. "systemctl status crond" in RHEL9 if
/etc/systemd/system/crond.service
-> /ram/etc/systemd/system/crond.service
-> /usr/lib/systemd/system/.crond.service.blah.blah
-> /usr/lib/systemd/system/crond.service
