It seems that `pam_systemd` was the only thing left that wanted to use sockets
in file system path `/tmp/.X11-unix/X*`. X11 apps actually prefer using the
abstract socket version.
This allows running Xserver with `-nolisten tcp -nolisten unix`, which makes
the server only listen to an abstract socket.
Also in my setup, Xserver is running as a separate system service instead of
starting from display manager service, and now `PrivateTmp=yes` can be used for
both. The file system of the display manager service is inherited by user apps
and now their `/tmp` will be separate from `/tmp` of PID1 namespace as well as
`/tmp` of Xserver.
Any recent shim will refuse starting an image that does not have an sbat section
and will do so with a generic "Security Violation" message. And it is very easy
to forget passing -Dsbat-distro=auto to meson when creating a fresh build dir.
Adding sbat info when shim is not used or secure boot is disabled does not hurt
anyone, so default to auto. This still ensures to not add auto-detected info in
case we are cross building.
Note that test-cgroup-mask, test-cgroup-unit-default and test-unit-name will now
report being skipped instead of reporting success if not run under systemd.
Note that this will only report test skips if they use TEST_RET macro.
Regular TEST macros can still be skipped, but this will not be reported
back to main();
In case `/proc` is successfully mounted with pid tree subset only due to
`ProcSubset=pid`, the protective mounts for `ProtectKernelTunables=yes` and
`ProtectKernelLogs=yes` to non-pid `/proc` paths are failing because the paths
don't exist. But the pid only option may have failed gracefully (for example
because of ancient kernel), so let's try the mounts but it's not fatal if they
don't succeed.
00db9a114e ("docs: generate table from header using a script") got the
descriptions for the partition types mixed up. After that change, the
spec claimed, for example, that the /usr partition should contain
"dm-verity integrity hash data for the matching root partition", and
that the /usr verity partition should be of type "Any native, optionally
in LUKS". This made the spec an extremely confusing read before I
figured out what must have happened!
I've gone through the table as it existed prior to 00db9a114e, and moved
the descriptions around in the script that generates the table until
they matched up with what they used to be. Then I regenerated the
table from the fixed script.
Allows to pass a portable profile when doing offline analysis of
units. Especially useful for analyzing portable images, since a
lot of the security-relevant settings in those cases come from
the profiles, but they are not shipped in the portable images.
I think the function name is confusing: we generally say "free_free" when
both keys and values are freed in a hash map, but here the type is an
array of strvs, so the name should be something like strv_array_free.
The function is unused since 143fadf369 (2018),
let's just drop it.
Make oomctl a bit less likely to race with systemd-oomd receiving the
managed oom cgroup info by checking oomctl output in a loop with
timeout.
