Pull apparmor updates from John Johansen:
"This has one major feature, it pulls in a cleaned up version of
af_unix mediation that Ubuntu has been carrying for years. It is
placed behind a new abi to ensure that it does cause policy
regressions. With pulling in the af_unix mediation there have been
cleanups and some refactoring of network socket mediation. This
accounts for the majority of the changes in the diff.

In addition there are a few improvements providing minor code
optimizations. several code cleanups, and bug fixes.

Features:
- improve debug printing
- carry mediation check on label (optimization)
- improve ability for compiler to optimize
__begin_current_label_crit_section
- transition for a linked list of rulesets to a vector of rulesets
- don't hardcode profile signal, allow it to be set by policy
- ability to mediate caps via the state machine instead of lut
- Add Ubuntu af_unix mediation, put it behind new v9 abi

Cleanups:
- fix typos and spelling errors
- cleanup kernel doc and code inconsistencies
- remove redundant checks/code
- remove unused variables
- Use str_yes_no() helper function
- mark tables static where appropriate
- make all generated string array headers const char *const
- refactor to doc semantics of file_perm checks
- replace macro calls to network/socket fns with explicit calls
- refactor/cleanup socket mediation code preparing for finer grained
mediation of different network families
- several updates to kernel doc comments

Bug fixes:
- fix incorrect profile->signal range check
- idmap mount fixes
- policy unpack unaligned access fixes
- kfree_sensitive() where appropriate
- fix oops when freeing policy
- fix conflicting attachment resolution
- fix exec table look-ups when stacking isn't first
- fix exec auditing
- mitigate userspace generating overly large xtables"

apparmor: transition from a list of rules to a vector of rules

The set of rules on a profile is not dynamically extended, instead
if a new ruleset is needed a new version of the profile is created.

apparmor: transition from a list of rules to a vector of rules

The set of rules on a profile is not dynamically extended, instead
if a new ruleset is needed a new version of the profile is created.
This allows us to use a vector of rules instead of a list, slightly
reducing memory usage and simplifying the code.

Merge tag 'apparmor-pr-2023-11-03' of git://git.kernel.org/pub/scm/linux/kernel/git/jj/linux-apparmor

Pull apparmor updates from John Johansen:
"This adds initial support for mediating io_uring and userns creation.
Adds a new restriction that tightens the use of change_profile, and a
couple of optimizations to reduce performance bottle necks that have
been found when retrieving the current task's secid and allocating
work buffers.

The majority of the patch set continues cleaning up and simplifying
the code (fixing comments, removing now dead functions, and macros
etc). Finally there are 4 bug fixes, with the regression fix having
had a couple months of testing.

Features:
- optimize retrieving current task secid
- add base io_uring mediation
- add base userns mediation
- improve buffer allocation
- allow restricting unprivilege change_profile

Cleanups:
- Fix kernel doc comments
- remove unused declarations
- remove unused functions
- remove unneeded #ifdef
- remove unused macros
- mark fns static
- cleanup fn with unused return values
- cleanup audit data
- pass cred through to audit data
- refcount the pdb instead of using duplicates
- make SK_CTX macro an inline fn
- some comment cleanups

Bug fixes:
- fix regression in mount mediation
- fix invalid refenece
- use passed in gfp flags
- advertise avaiability of extended perms and disconnected.path"

apparmor: refcount the pdb

With the move to permission tables the dfa is no longer a stand
alone entity when used, needing a minimum of a permission table.
However it still could be shared among different pdbs each using
a different permission table.

Instead of duping the permission table when sharing a pdb, add a
refcount to the pdb so it can be easily shared.
