Subject: [PATCH] filterAdvisory: match installed_solvables sort with lower_bound (RhBug:2212838)
`std::lower_bound` expects that the range it operates on is sorted by
the provided comparator.
`lower_bound()` is used on `installed_solvables` twice, first with
comparator `NameSolvableComparator` and later with
`SolvableCompareAdvisoryPkgNameArch` to cover both we need to sort
`installed_solvables` by name and arch.
Otherwise this can lead to problems if multiple architectures of a pkg
are installed.

Subject: [PATCH] hawkey.subject: get_best_selectors only obsoleters of latest
In situation where a package exists in multiple versions and some older
version is being obsoleted, any of obsoleters was considered a valid
solution.
The result could be really misleading. For example let's have this package set:
systemd-udev-1.0
systemd-udev-2.0
Obsoletes: systemd-udev < 2
systemd-boot-unsigned-2.0
Obsoletes: systemd-udev < 2
In this case `dnf install systemd-udev` may lead to installation of
systemd-boot-unsigned which is probably not what the user expected. The
reason is the split in the upgrade-path created by obsolete and both
branches - systemd-udev-2.0 and systemd-boot-unsigned-2.0 are considered
valid.
With this patch install command takes into account only obsoleters of
the best version of the package so the `dnf install systemd-udev`
results in correct installation of systemd-udev-2.0 package.

Subject: [PATCH] Avoid reinstalling installonly packages marked for ERASE
Without this patch reinstalling installonly pkg marked for ERASE might
be a valid smallest solution to our job.
For example when user wants to install through a provide we select all
packages that provide it and put them inside a `job install oneof ...`
if one of the providers is also marked for ERASE due to installonly
limit libsolv might decide to reinstall it.
To make sure it doesn't happen mark the available package also as ERASE.

Subject: [PATCH] PGP: Set a default creation SELinux labels on GnuPG
directories
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
libdnf used to precreate the directory in /run/user to make sure
a GnuPG agent executed by GPGME library places its socket there.
The directories there are normally created and removed by systemd
(logind PAM session). libdnf created them for a case when a package
manager is invoked out of systemd session, before the super user logs
in. E.g. by a timer job to cache repository metadata.
A problem was when this out-of-session process was a SELinux-confined
process creating files with its own SELinux label different from a DNF
program. Then the directory was created with a SELinux label different
from the one expected by systemd and when logging out a corresponding
user, the mismatching label clashed with systemd.
The same issue was with temporary GnuPG home directories created by
libdnf under /tmp.
This patch fixes both the isseus by restoring a SELinux label of those
directories to the label defined in a default SELinux file context
database.
Obviously the database cannot have a record for a nonspecific
/tmp/tmpdir.XXXXXX (a mkdtemp() template) directory names. Therefore
I changed their names to more specific /tmp/libdnf.XXXXXX. Once
a SELinux policy updates the database, directories under /tmp will get
a correct label.
There is yet another problem with accessing /var/cache/dnf/*/pubring,
but that seems to be pure SELinux policy problem.
This patch adds a new -DENABLE_SELINUX=OFF CMake option to disable the
new dependency on libselinux. A default behavior is to support SELinux.
Implementation details:
I used selabel_lookup() + setfscreatecon() + mkdtemp()
+ setfscreatecon() sequence instead of mkdtemp()
+ selinux_restorecon() sequence because the later polutes stderr if
a SELinux policy does not define the default context. One could
supress stderr messages with selinux_set_callback(), but its effect
cannot be restored.
I also kept the sequence in one function and reused it for creating
/run/user/$PID directories because the code is simpler than spliting
the function into three parts.

The default for container execution is that `/sys/fs/selinux`
is not mounted, and the libselinux library function `is_selinux_enabled`
should be used to dynamically check if the system should attempt to perform SELinux labeling.
This is how it's done by rpm, ostree, and systemd for example.
But this code unconditionally tries to label if it finds a policy,
which breaks in an obscure corner case
when executed inside a container that includes policy files (e.g.
fedora/rhel-bootc) but when we're not using overlayfs for the backend
(with BUILDAH_BACKEND=vfs).
