I propose this patch for master and 3.x (the profile in 2.13 is very different which makes automatic merging impossible)

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`.

(cherry picked from commit 763c4ecd23,

usr.sbin.winbindd dropped)

1759c1bd24 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>`

677051bd02 Merge 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/
current-open/
legacy-340xx/
legacy-390xx/
tesla/
tesla-418/
tesla-450/
tesla-460/
tesla-470/
tesla-510/
```

These paths are used by nvidia_modprobe -> kmod:

```

```

Also, additional /sys path is accessed:

```
type=AVC msg=audit(1676136251.680:2956): apparmor="DENIED" operation="open" profile="nvidia_modprobe//kmod" name="/sys/module/drm/initstate" pid=63642 comm="modprobe" requested_mask="r" denied_mask="r" fsuid=0 ouid=0FSUID="root" OUID="root"
```

Update nvidia_modprobe profile to this these denials.

5bc35342ed 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).

465c861b02 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.

abstraction/exo-open: Remove dbus deny rule
Abstractions should not generally include deny rules as this can unduly
constrain profiles which include them due to the precedent matching rules
between deny vs allow rules. Also as per the comment, this is not required
for exo-open to work, so simply omit it from the abstraction for
now. Finally, in Ubuntu, the evince profile includes the exo-open
abstraction and this deny rule causes evince to fail to initialise
correctly as it then assumes it cannot use gvfs.
