Subject: [PATCH] pager: set $LESSSECURE whenver we invoke a pager
Some extra safety when invoked via "sudo". With this we address a
genuine design flaw of sudo, and we shouldn't need to deal with this.
But it's still a good idea to disable this surface given how exotic it
is.
Prompted by #5666

Subject: [PATCH] test-login: always test sd_pid_get_owner_uid(), modernize
A long time some function only worked when in a session, and the test
didn't execute them when sd_pid_get_session() failed. Let's always call
them to increase coverage.
While at it, let's test for ==0 not >=0 where we don't expect the function
to return anything except 0 or error.

Subject: [PATCH] pager: make pager secure when under euid is changed or
explicitly requested
The variable is renamed to SYSTEMD_PAGERSECURE (because it's not just about
less now), and we automatically enable secure mode in certain cases, but not
otherwise.
This approach is more nuanced, but should provide a better experience for
users:
- Previusly we would set LESSSECURE=1 and trust the pager to make use of
it. But this has an effect only on less. We need to not start pagers which
are insecure when in secure mode. In particular more is like that and is a
very popular pager.
- We don't enable secure mode always, which means that those other pagers can
reasonably used.
- We do the right thing by default, but the user has ultimate control by
setting SYSTEMD_PAGERSECURE.
Fixes #5666.
v2:
- also check $PKEXEC_UID
v3:
- use 'sd_pid_get_owner_uid() != geteuid()' as the condition
(cherry picked from commit 0a42426d797406b4b01a0d9c13bb759c2629d108)

Subject: [PATCH] test: ignore ENOMEDIUM error from sd_pid_get_cgroup()
Ubuntu builds on the Launchpad infrastructure run inside a chroot that does
not have the sysfs cgroup dirs mounted, so this call will return ENOMEDIUM
from cg_unified_cached() during the build-time testing, for example when
building the package in a Launchpad PPA.
(cherry picked from commit 352ab9d74049b4ac694fdba1a6e67339f12ded93)

Subject: [PATCH] pstore: fix crash and forward dummy arguments instead of NULL
[msekleta: in our version of systemd "const char path*" argument of
path_join() can't be NULL. Here we don't really want any subdirs paths
passed into move_file(), but we can't just pass NULL pointers because
they will be forwarded to path_join(). Hence, let's just pass "/"
instead.]

Subject: [PATCH] ci: first part of the source-git automation - commit linter
Add a GitHub Workflow that is triggered on `workflow_run` events.
It uses metadata provided by `redhat-plumbers-in-action/gather-pull-request-metadata`
GitHub Action to get the PR number and the commit metadata.
The commit metadata is then used to check if the commit message contains
all required information (tracker and upstream reference). GitHub Action
responsible for commit verification `redhat-plumbers-in-action/advanced-commit-linter`
is configured via the `advanced-commit-linter.yml` file.
