abstractions/base: allow reading tzdata ICU zoneinfo DB
This is used by various applications including libreoffice etc so it may as well
be added to the base abstraction along with the existing zoneinfo DB access.

7fa20770db Merge tunables/etc: Improve comments which variable to use
The description of @{etc_ro} and @{etc_rw} were not good enough in
explaining which directories they should contain, and when to use which
of the variables in a profile.

I propose this patch for all branches.

See also https://bbs.archlinux.org/viewtopic.php?id=281411

Since `usr.sbin.winbindd` already has a rule for it, and `usr.sbin.nmbd`
has similar ones, simply add `/var/cache/samba/*.tdb rwk` to
`abstractions/samba`.

8e50c351e1 nvidia_modprobe: update for driver families and /sys path
Debian have split NVIDIA drivers into current, tesla and legacy:

```
$ apt-file search /etc/nvidia/ | grep -P -o -e
"(?<=/etc/nvidia/).[^/]*/" | sort -u
current/

legacy-340xx/
legacy-390xx/
tesla/
tesla-418/

tesla-460/
tesla-470/

```

These paths are used by nvidia_modprobe -> kmod:

```

```

Also, additional /sys path is accessed:

Note: in the `firefox.sh` profile, the local include was added just today, therefore I think changing it (instead of adding) should be fine.

238eb8150b Merge Add abstractions/groff with lots of groff/nroff helpers
contributed by Werner Fink via
https://bugzilla.opensuse.org/show_bug.cgi?id=1065388 comment 25

Note that - compared to the file in bugzilla - I removed the `rix` rules
for /usr/bin/groff and /usr/bin/nroff so that people can choose to ix,
Px or Cx groff/nroff as they wish, and then include the abstraction
inside the target profile to allow executing all the helpers.

I also added `include if exists <abstractions/groff.d>`

5fd8c25745 Merge Fix: Opening links with Brave
Resolves #292.

This fix is the same as !830 but for Brave.
Opening links in Brave now works as intended.

Note that now a separate denial is caused, related to WidevineCDM, is produced:
```
[ERROR:content_main_runner_impl.cc(415)] Unable to load CDM /home/username/.config/BraveSoftware/Brave-Browser/WidevineCdm/4.10.2557.0/_platform_specific/linux_x64/libwidevinecdm.so (error: /home/username/.config/BraveSoftware/Brave-Browser/WidevineCdm/4.10.2557.0/_platform_specific/linux_x64/libwidevinecdm.so: failed to map segment from shared object)
```

In the syslog:
```
audit: type=1400 audit(1671108748.090:117): apparmor="DENIED" operation="file_mmap" profile="/usr/bin/evince//sanitized_helper" name="/home/username/.config/BraveSoftware/Brave-Browser/WidevineCdm/4.10.2557.0/_platform_specific/linux_x64/libwidevinecdm.so" pid=65765 comm="brave" requested_mask="m" denied_mask="m" fsuid=1000 ouid=100
```

I'm not sure if granting permission(s) for this is desirable. In either case, the potential relevant changes are out of the scope of this MR.

If I disable WidevineCDM in Brave, I get the following denial on cap sys_admin:
```
audit: type=1400 audit(1671112807.666:174): apparmor="DENIED" operation="capable" profile="/usr/bin/evince//sanitized_helper" pid=112098 comm="brave" capability=21  capname="sys_admin"
```
which is fine, as mentioned by @jjohansen [here](https://gitlab.com/apparmor/apparmor/-/merge_requests/830#note_831915024).

c159d0925a Allow access to possible cpus for glibc-2.36
Glibc in 2.36 and later will [1] access sysfs at
/sys/devices/system/cpu/possible when usig sysconf
for _SC_NPROCESSORS_CONF.

That will make a lot of different code, for example
anything linked against libnuma, trigger this apparmor
denial.

  apparmor="DENIED" operation="open" class="file" ...
  name="/sys/devices/system/cpu/possible" ...
  requested_mask="r" denied_mask="r" fsuid=0 ouid=0

This entry seems rather safe, and it follows others
that are already in place. Instead of fixing each
software individually this should go into the base
profile as well.

8fa77e9e6c Merge Adds WSL programmatic management of /etc/resolv.conf.
When WSL automatically generates a resolv.conf for an instance, the /etc/resolv.conf file is a symlink to /mnt/wsl/resolv.conf. This patch adds an entry for this to the other policies to handle such management.

path:
  [global]
  ; Pid file
  ; Note: the default prefix is @EXPANDED_LOCALSTATEDIR@
  ; Default Value: none
  ;pid = run/php-fpm.pid

Add this path to profiles/apparmor.d/php-fpm, alongside the current
nested "@{run}/php{,-fpm}/php*-fpm.pid" wildcard.
