crypto: af_alg - Avoid sock_graft call warning
The newly added sock_graft warning triggers in af_alg_accept.
It's harmless as we're essentially doing sock->sk = sock->sk.
The sock_graft call is actually redundant because all the work
it does is subsumed by sock_init_data. However, it was added
to placate SELinux as it uses it to initialise its internal state.
This patch avoisd the warning by making the SELinux call directly.

refcount_t type and corresponding API should be
used instead of atomic_t when the variable is used as
a reference counter. This allows to avoid accidental
refcounter overflows that might lead to use-after-free
situations.
This patch uses refcount_inc_not_zero() instead of
atomic_inc_not_zero_hint() due to absense of a _hint()
version of refcount API. If the hint() version must
be used, we might need to revisit API.

The test considers a party that already has a private-public
key pair and a party that provides a NULL key. The kernel will
generate the private-public key pair for the latter, computes
the shared secret on both ends and verifies if it's the same.

the previous test vector.

Add support for generating ecc private keys.
Generation of ecc private keys is helpful in a user-space to kernel
ecdh offload because the keys are not revealed to user-space. Private
key generation is also helpful to implement forward secrecy.
If the user provides a NULL ecc private key, the kernel will generate it
and further use it for ecdh.
Move ecdh's object files below drbg's. drbg must be present in the kernel
at the time of calling.

The tcrypt AEAD cycles speed tests disables irqs during the test, which is
broken at the very least since commit
'1425d2d17f7309c6 ("crypto: tcrypt - Fix AEAD speed tests")'
adds a wait for completion as part of the test and probably since
switching to the new AEAD API.
While the result of taking a cycle count diff may not mean much on SMP
systems if the task migrates, it's good enough for tcrypt being the quick
& dirty dev tool it is. It's also what all the other (i.e. hash) cycle
speed tests do.

There are many code paths opencoding kvmalloc. Let's use the helper
instead. The main difference to kvmalloc is that those users are
usually not considering all the aspects of the memory allocator. E.g.
allocation requests <= 32kB (with 4kB pages) are basically never failing
and invoke OOM killer to satisfy the allocation. This sounds too
disruptive for something that has a reasonable fallback - the vmalloc.
On the other hand those requests might fallback to vmalloc even when the
memory allocator would succeed after several more reclaim/compaction
attempts previously. There is no guarantee something like that happens
though.
This patch converts many of those places to kv[mz]alloc* helpers because
they are more conservative.

Some cipher implementations will crash if you try to use them
without calling setkey first. This patch adds a check so that
the accept(2) call will fail with -ENOKEY if setkey hasn't been
done on the socket yet.

Add scomp backend for zlib-deflate compression algorithm.
This backend outputs data using the format defined in rfc1950
(raw deflate surrounded by zlib header and footer).

The cipher_null is not a real cipher, FIPS mode should not restrict its use.
It is used for several tests (for example in cryptsetup testsuite) and also
temporarily for reencryption of not yet encrypted device in cryptsetup-reencrypt tool.
Problem is easily reproducible with
cryptsetup benchmark -c null

Compression implementations might return valid outputs that
do not match what specified in the test vectors.
For this reason, the testmgr might report that a compression
implementation failed the test even if the data produced
by the compressor is correct.
This implements a decompress-and-verify test for acomp
compression tests rather than a known answer test.
