In later patches, we're going to change how the inode's ctime field is
used. Switch to using accessor functions instead of raw accesses of

Back in 2008 we extended the capability bits from 32 to 64, and we did
it by extending the single 32-bit capability word from one word to an
array of two words. It was then obfuscated by hiding the "2" behind two
macro expansions, with the reasoning being that maybe it gets extended
further some day.
That reasoning may have been valid at the time, but the last thing we
want to do is to extend the capability set any more. And the array of
values not only causes source code oddities (with loops to deal with
it), but also results in worse code generation. It's a lose-lose
situation.
So just change the 'u32[2]' into a 'u64' and be done with it.
We still have to deal with the fact that the user space interface is
designed around an array of these 32-bit values, but that was the case
before too, since the array layouts were different (ie user space
doesn't use an array of 32-bit values for individual capability masks,
but an array of 32-bit slices of multiple masks).
So that marshalling of data is actually simplified too, even if it does
remain somewhat obscure and odd.
This was all triggered by my reaction to the new "cap_isidentical()"
introduced recently. By just using a saner data structure, it went from
unsigned __capi;
CAP_FOR_EACH_U32(__capi) {
if (a.cap[__capi] != b.cap[__capi])
return false;
}
return true;
to just being
return a.val == b.val;
instead. Which is rather more obvious both to humans and to compilers.

The rawdata readback has a few of problems. First if compression is
enabled when the data is read then the compressed data is read out
instead decompressing the data. Second if compression of the data
fails, the code does not handle holding onto the raw_data in
uncompressed form. Third if the compression is enabled/disabled after
the rawdata was loaded, the check against the global control of
whether to use compression does not reflect what was already done to
the data.
Fix these by always storing the compressed size, along with the
original data size even if compression fails or is not used. And use
this to detect whether the rawdata is actually compressed.

The v8 abi is supported by the kernel but the userspace supported
version check does not allow for it. This was missed when v8 was added
due to a bug in the userspace compiler which was setting an older abi
version for v8 encoding (which is forward compatible except on the
network encoding). However it is possible to detect the network
encoding by checking the policydb network support which the code
does. The end result was that missing the abi flag worked until
userspace was fixed and began correctly checking for the v8 abi
version.

Change the algorithm used by apparmor to compress profile data from
zlib to zstd, using the new zstd API introduced in 5.16.
Zstd provides a larger range of compression levels than zlib and
significantly better performance at the default level (for a relatively
small increase in compressed size).
The apparmor module parameter raw_data_compression_level is now clamped
to the minimum and maximum compression levels reported by the zstd
library. A compression level of 0 retains the previous behavior of
disabling policy compression instead of using zstd's behavior, which is
to use the default compression level.
