This manifested with chmod calls failing in autopkgtests of dbus and snapd.
Given the magnitude of regressions that might be caused by bugs in this profile, @alex_murray has suggested disabling the profile by default (i.e. moving it into `extras/`).

The original plan was to have a minimal subset for Perl excluding the stuff requiring language-dependent typemaps, but it turns out that there was only one thing that required that, and it was simple enough to copy over from the SWIG repo itself. This MR contains the single non-language-generic part of the SWIG updates.

This is the only language-dependent nontrivial portion of the SWIG
bindings, and this should be good enough for anyone who is still using the
Perl bindings now

When a test fails because of an unexpected success (XFAIL), do not display the empty error log as that may confuse the reader just as it had confused the author.
In addition, when something legitimately fails then display tail of trace log as that may show some useful information.

Rename the template file from
com.ubuntu.pkexec.aa-notify.policy
to

And update the template file and the install file so that the files
that are generated use net.apparmor instead of com.ubuntu

The install of the polkit action files for aa-notify leaks build root
information.
From OBS
apparmor-utils.noarch: E: file-contains-buildroot (Badness: 10000) /usr/share/polkit-1/actions/com.ubuntu.pkexec.aa-notify.policy
this is present on Ubuntu as well

this occurs because the {LIB_PATH} template variable is being replaced
with the self.install_lib. Make sure we strip the build prefix if
we are generating the files in a build environment instead of doing
a direct install.

This PR only adds the digit `@{d}` and integer `@{int}` variables.
It provides two improvements from the use of the `[0-9]*` glob:
- security: the glob means "a digit followed by anything but `/`", whereas `@{int}` means "up to 10 digits"
Next to the
- stability: using glob in path with `x` can expose to path conflict, removing the glob fixed a lot of issues.
These variables are used by a lot of abstractions that could be upstream here from apparmor.d (PR will follow). It is an import from 33681e14f2/apparmor.d/tunables/multiarch.d/system where other similar variables are in use: `@{hex}`, `@{rand}`, `@{word}`, `@{u8}`, `@{u16}`, `@{u64}`, `@{int2}...@{int64}` ...
They also all could be upstreamed here.

On certain lxc containers, when aa-genprof tries to set
printk_ratelimit, it fails with the OSError exception, with the
message "OSError: [Errno 30] Read-only file system" instead of
PermissionError.
Since PermissionError is a subclass of OSError, replace it by broader
OSError exception to include both cases in which running aa-genprof
fails.

- specifying messages for `static_assert` declarations (required up until C23, was accepted as a compiler extension on the systems I had tested this on previously)
- removing label-followed-by-declaration instance (also a C23 feature supported as extension)

The documentation was missing information about path sanitization, and
why you shouldn't do a leading @{VAR} on path rules. While the example
doing this was fixed, actual information about why you shouldn't do
this was missing.
Document how apparmor will collapse consecutive / characters into a
single character for paths, except when this occurs at the start of
the path.

The previous code using intmax_t failed to build on armhf because
intmax_t was long long int instead of long int on that platform.
As to shrinking down to a long: not only does SWIG lack a
SWIG_AsVal_intmax_t, but aalogparse also assumes PIDs fit in a long
by storing them as unsigned longs in aa_log_record. Thus, we can
assume that sizeof(pid_t) <= sizeof(long) right now and deal with
the big headache that a change to pid_t would cause if it becomes
larger than a long in the future.

The unshare-userns-restrict profile contained a cx transition to
transition to a profile that allows most things while denying
capabilities:
audit allow cx /** -> unpriv,
However, this transition does not stack the unshare//unpriv profile
against any other profile the target binary might have had. As a result,
the lack of stacking resulted in a non-namespace-related sandboxing
bypass in which attachments of other profiles that should have confined
the target binary do not get applied. Instead, we adopt a stack similar
to the one in bwrap-userns-restrict, with the exception that unshare
does not use no-new-privs and therefore only needs a two-layer stack
instead of a three-layer stack.
