One example where this is needed is in the xcbc(aes) shared descriptors,
which are updated in current patch.

ERN handler calls the caam/qi frontend "done" callback with a status
of -EIO. This is incorrect, since the callback expects a status value
meaningful for the crypto engine - hence the cryptic messages
like the one below:
platform caam_qi: 15: unknown error source

Fix this by providing the callback with:
-the status returned by the crypto engine (fd[status]) in case
it contains an error, OR
-a QI "No error" code otherwise; this will trigger the message:
platform caam_qi: 50000000: Queue Manager Interface: No error
which is fine, since QMan driver provides details about the cause of
failure

IV transfer from ofifo to class2 (set up at [29][30]) is not guaranteed

If ofifo -> external memory transfer happens first, DECO will hang

Make sure IV transfer happens first by waiting for all CAAM internal

Recent clang-9 snapshots double the kernel stack usage when building
this file with -O0 -fsanitize=kernel-hwaddress, compared to clang-8
and older snapshots, this changed between commits svn364966 and
svn366056:

crypto/jitterentropy.c:516:5: error: stack frame size of 2640 bytes in function 'jent_entropy_init' [-Werror,-Wframe-larger-than=]
int jent_entropy_init(void)
    ^

             ^

I prepared a reduced test case in case any clang developers want to
take a closer look, but from looking at the earlier output it seems
that even with clang-8, something was very wrong here.

Turn off any KASAN and UBSAN sanitizing for this file, as that likely
clashes with -O0 anyway.  Turning off just KASAN avoids the warning
already, but I suspect both of these have undesired side-effects
for jitterentropy.

this header does not exist on many architectures, resulting in

To help avoid confusion, add a comment to ghash-generic.c which explains
the convention that the kernel's implementation of GHASH uses.

Also update the Kconfig help text and module descriptions to call GHASH
a "hash function" rather than a "message digest", since the latter
normally means a real cryptographic hash function, which GHASH is not.

With the removal of the padata timer, padata_do_serial no longer
needs special CPU handling, so remove it.

Validated assoclen for RFC4543 which expects an assoclen
of 16 or 20, the same as RFC4106.
Based on seqiv, IPsec ESP and RFC4543/RFC4106 the assoclen is sizeof
IP Header (spi, seq_no, extended seq_no) and IV len. This can be 16 or
20 bytes.

Check assoclen to solve the extra tests that expect -EINVAL to be
returned when the associated data size is not valid.
