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.

This is a manual backport of
728dbde5e4 by Mark Grassi
For the records: the inconsistent return length was introduced when
splitting run_tests() into two functions in
500cbf89a7
The inverse character set lists the characters it doesn't match. If
the inverse character set contains an oob then that is NOT considered
a match. So length should be one.
However because of oobs are handle not containing an oob doesn't mean
there is a match either. Currently the only way to match an oob is
via a positive express (no inverse matches are possible).

The snap_browsers abstraction requires more permissions
due to updates on snaps.
Some of the permissions are not required in older versions of
Ubuntu that use 2.12 and 2.13, but are introduced for unification

```
all dbus permissions,

As a short-term solution, we are adding a snap-browsers profile
which restricts what snaps opened by evince can do.
The long-term solution is currently not available, but could be
accomplished by using enhanced environment variable filtering/mediation
and delegation of open fds.

If apparmor_parser -N (in profiles_names_list()) fails,
aa-remove-unknown possibly gets an incomplete list of profiles in
/etc/apparmor.d/ and therefore might remove more profiles than it
should.
Replace the profiles_names_list() call with a direct apparmor_parser
call, and abort aa-remove-unknown if it exits with $? != 0
Before:
```
aa-remove-unknown -n
AppArmor parser error for /etc/apparmor.d/broken in profile /etc/apparmor.d/broken at line 1: syntax error, unexpected TOK_ID, expecting TOK_OPEN

Since the 'smb' machine is a container, the Apparmor denial ended up in the host's log:
```

```
It is the first time it occurs in years of use but it seems legitimate as:
1) this file is installed by the package
2) `git grep -F elasticsearch_mappings` in Debian samba's source shows many hits:
```

While only the `mdssvc` sub-dir could be authorized, the whole dir content seemed OK for read access anyway:

In 73e124d4fb I've upstreamed the `is_container_with_internal_policy()` function, but so far it was not used anywhere upstream. This is the missing bit.
I could trace the history of that patch back to 2012 (2.7.102-0ubuntu3):
* debian/apparmor.init: do nothing in a container. This can be
removed once stacked profiles are supported and used by lxc.
(LP: #978297)
Context: I lack both knowledge and motivation to keep maintaining this as part of the Debian delta. I'd rather see upstream, and in particular folks more knowledgeable than me about LXC/LXD, or with external motivation factors to work on this part of the stack, take care of it.
Note: Debian has similar code in its [sysvinit script](https://salsa.debian.org/apparmor-team/apparmor/-/blob/debian/master/debian/apparmor.init). I'm not touching that one.

GTK/QT apps need to read some config files in order to properly render their windows in a graphical session. There are some `qt5` abstractions already, but it looks like the `gtk` abstraction is missing.
The `*gtk*` rules are basically the location of the GTK config files I found on the internet when I was trying to compose this abstraction. Some of the paths are missing in Debian, but different distros can use (or were using) them. Since GTK apps use themes, the abstraction also include the whole `/usr/share/themes/` , `@{HOME}/.themes/` and `@{HOME}/.local/share/themes/` dirs. I'm not sure whether this should be tightened. The `.Xauthority` file is generally needed when you deal with GUI apps under Xserver. Also since all GUI apps redirect output/error to the `~/.xsession-errors` file, this file also was included here.

While we are here, also add -r (--no-run-if-empty, which also has no long equivalent for busybox) as we likely don't want to run anything if no profile were found

The byte position of the timestamp is also different on each

endian.
Note that this MR includes more things, like
* moving `get_last_login_timestamp()` to the new `apparmor/notify.py` file
* add unit tests for it
* add wtmp example files from various architectures, including a
hand-edited one claiming to be from 1999
* fixing a bug in `get_last_login_timestamp()` that unpacked `type` from
too many bytes - which accidently worked on x86_64
* detecting from which architecture the wtmp file comes (luckily the
timestamps are located at different locations)

'type' is a short (see "ut_type" in wtmp(5)), therefore only read two
bytes and unpack them as short. Afterwards read two padding bytes to
/dev/null.
This accidently worked on x86_64 because it's little endian, but will
fail on big endian architectures.

Some STATUS log events trigger a crash in aa-notify because the log
line doesn't have operation=. Examples are:
type=AVC msg=audit(1630913351.586:4): apparmor="STATUS" info="AppArmor Filesystem Enabled" pid=1 comm="swapper/0"
type=AVC msg=audit(1630913352.610:6): apparmor="STATUS" info="AppArmor sha1 policy hashing enabled" pid=1 comm="swapper/0"
Fix this by not looking at log events without operation=
Also add one of the example events as libapparmor testcase.

Merge branch 'fix-policy-cache-regression-tests' into 'master'
When using the system parser ${parser_config} will be empty and so if this
is unconditionally passed as an argument to the parser then this gets in
interpreted as the name of a file to be compiled and hence the parser just
prints:
File not found, skipping...
File not found, skipping...
File not found, skipping...
...
for all the aa_policy_cache tests - instead fix this to pass a single args
argument to the parser which will only include parser_config if it is not
empty.
This fixes the regression tests to run to completion without error when
USE_SYSTEM=1 is set.

libapparmor performs a test for the new stacking interface, however
how it does this test is problematic as it requires all confined
tasks to be given read access to the task introspection interface.
This results in tasks needing to be given read access to the interface
even if they don't need it. Making it possible for tasks to discover
their confinement even if they are not supposed to be able to.
Instead change the check to using state on the parent directory.
This will generate a getattr request instead of read and make it
on the directory instead of on any interface file that could be
used to obtain information.

Adjust the interface check and fallback. Unfortunately there is no
solution that will fix all failure cases. Instead try to minimize
the failure cases and bias towards failures that don't cause a
regression under an old parser/policy.
Note: In cases where we absolutely know the interface should not
be accessed fail those accesses imediately instead of relying
on what ever LSM active to handle it.
While we are at it document the interfaces and failure cases.

Also set the correct variable, as previously we were not.
Note: that skipping checking available for the private apparmor
proc interfaces is okay, as the dedicated apparmor interfaces will
fail correctly if available is False.
This just gives a clear way for userspace to query this info without

Currently the wutmp abstraction has the following rules:
/var/log/lastlog rwk,
/var/log/wtmp wk,
@{run}/utmp rwk,
According to what I see in my apparmor profiles, just a few apps want
to interact with the files listed above, especially with the
/var/log/wtmp . But when the apps do this, they sometimes want the
read access to this file. An example could be the last command. Is
there any reason for not having the r in the rule? The second thing
is the file /var/log/btmp (which isn't included in the
abstracion). Whenever I see an app, which wants to access the
/var/log/wtmp file, it also tries to interact with the /var/log/btmp
file, for instance lightdm/sddm or su . Most of the time they need
just wk permissions, but sometimes apps need also r on this file, an
example could be the lastb command, which is just a link to last.

Rule downgrades are used to provide some confinement when a feature
is only partially supported by the kernel.
Eg. On a kernel that doesn't support fine grained af_unix mediation
but does support network mediation.
unix (connect, receive, send)
type=stream
peer=(addr="@/tmp/.ICE-unix/[0-9]*"),
will be downgraded to
network unix type=stream,
Which while more permissive still provides some mediation while
allowing the appication to still function. However making the rule
a deny rule result in tightening the profile.
Eg.
deny unix (connect, receive, send)
type=stream
peer=(addr="@/tmp/.ICE-unix/[0-9]*"),
will be downgraded to
deny network unix type=stream,
and that deny rule will take priority over any allow rule. Which means
that if the profile also had unix allow rules they will get blocked by
the downgraded deny rule, because deny rules have a higher priority,
and the application will break. Even worse there is no way to add the
functionality back to the profile without deleting the offending deny
rule.
To fix this we drop deny rules that can't be downgraded in a way that
won't break the application.

My main user account is managed by systemd-homed. When I enable

not use sudo, etc.
This is the output of getent passwd:

But getent passwd rose and getent passwd 1000 both return no output.
Stopping nscd.service fixes these problems. Checking the apparmor

job scaling allows the parser to resample the number of cpus available
and increase the number of jobs that can be launched if cpu available
increases.
Unfortunately job scaling was being applied even when a fixed number
of jobs was specified. So
--jobs=2
doesn't actually clamp the compile at 2 jobs.
Instead job scaling should only be applied when --jobs=auto or when
jobs are set to a multiple of the cpus.

libapparmor on startup does detection of whether the new stacking
proc interfaces are available and then store a var for which interface
should be used. This avoids libapparmor needing to detect which interface
to use on each proc based api call.
Unfortunately if the domain is changed on the task via change_hat or
change_profile and the proc interface is used after the domain change
it is possible that access to the interface will be denied by policy.
This is not a problem in and of it self except policy may have been
created assuming the old interface.
Fix this by adding a fallback that tries the old interface if we
are using the new interface by default and the failure was due to
an EACCES denial (policy based).
Also refactor the code a bit so this retry is isolated to one function
instead of adding it in two places.

When run with the -p flag, aa-notify works fine for 100 seconds and then it exits.
I suspect that the issue arises from the following check on line 259 in utils/aa-notify
if debug_logger.debug_level <= 10 and int(time.time()) - start_time > 100:
debug_logger.debug('Debug mode detected: aborting notification emitter after 100 seconds.')
sys.exit(0)
together with line 301 in utils/apparmor/common.py which initializes debug_logger.debug_level to logging.DEBUG which has the numerical value 10.
A simple solution might be to just remove the check as I'm not quit sure why one would want aa-notify to exit when run in debug mode in the first place.
Alternatively, one could check against debug_logger.debugging (initialized to False) or change the initialization of debug_logger.debug_level to something else, but I don't know how that would affect other consumers of utils/apparmor/common.py.
For now just add dbugger_logger.debugging as an additional check as the
reason for timing out after 100s during debugging are unclear.
