a61f2802cb Merge fix mount regression in 3.1.5
Mount has regressed in two ways. That are affecting snapd confinement,
since landing the mount fixes for CVE-2016-1585 in 3.1.4 and the fix
for the mount ch ange type regression in 3.1.5

    Bug Reports:

    https://bugs.launchpad.net/apparmor/+bug/2023814

    https://bugzilla.opensuse.org/show_bug.cgi?id=1211989

Issue 1: Denial of Mount
    ```

    ```

    when the profile contains a rule that should match
    ```
    mount options=(rw, rbind) "/etc/" -> "/tmp/.snap/etc/",
    ```

Issue 2: change_type failure.

b85046648b parser: fix rule flag generation change_mount type rules
MR: https://gitlab.com/apparmor/apparmor/-/merge_requests/1048
made it so rules like

  mount slave /snap/bin/** -> /**,

  mount /snap/bin/** -> /**,

would get passed into change_mount_type rule generation when they
shouldn't have been. This would result in two different errors.

1. If kernel mount flags were present on the rule. The error would
   be caught causing an error to be returned, causing profile compilation
   to fail.

2. If the rule did not contain explicit flags then rule would generate
   change_mount_type permissions based on souly the mount point. And
   the implied set of flags. However this is incorrect as it should
   not generate change_mount permissions for this type of rule. Not
   only does it ignore the source/device type condition but it
   generates permissions that were never intended.

   When used in combination with a deny prefix this overly broad
   rule can result in almost all mount rules being denied, as the
   denial takes priority over the allow mount rules.

d6db84b120 Merge abstractions/base: Add transparent hugepage support
Found in testing a slimmed-down `usr.sbin.sshd` profile:
```
Jun  8 21:09:38 testvm kernel: [   54.847014] audit: type=1400 audit(1686272978.009:68): apparmor="DENIED" operation="open" profile="/usr/sbin/sshd" name="/sys/kernel/mm/transparent_hugepage/hpage_pmd_size" pid=1035 comm="sshd" requested_mask="r" denied_mask="r" fsuid=0 ouid=0

Not sure what glibc/system call uses this, but it seems pretty broadly applicable, and read access is presumably harmless. [THP reference](https://www.kernel.org/doc/html/latest/admin-guide/mm/transhuge.html)

a8fc656db2 Merge parser: fix parsing of source as mount point for propagation type flags
Before 300889c3a, mount rules would compile policy when using source
as mount point for rules that contain propagation type flags, such as
unbindable, runbindable, private, rprivate, slave, rslave, shared, and
rshared. Even though it compiled, the rule generated would not work as
expected.

This commit fixes both issues. It allows the usage of source as mount
point for the specified flags, albeit with a deprecation warning, and
it correctly generates the mount rule.

The policy fails to load when both source and mount point are
specified, keeping the original behavior (reference
parser/tst/simple_tests/mount/bad_opt_10.sd for example).

If `else if (preprocess_only)` is true, the more strict condition
`else if (!include_file && preprocess_only)` won't be reached if it gets
checked after the shorter condition.

Exchange the two sections so that both code paths can be reached.

This was probably introduced in 7dcf013bca / https://gitlab.com/apparmor/apparmor/-/merge_requests/743 which means we'll need to backport this fix to 3.0 and 3.1.
