CRYPTO_TFM_REQ_WEAK_KEY confuses newcomers to the crypto API because it
sounds like it is requesting a weak key. Actually, it is requesting
that weak keys be forbidden (for algorithms that have the notion of
"weak keys"; currently only DES and XTS do).
Also it is only one letter away from CRYPTO_TFM_RES_WEAK_KEY, with which
it can be easily confused. (This in fact happened in the UX500 driver,
though just in some debugging messages.)
Therefore, make the intent clear by renaming it to
CRYPTO_TFM_REQ_FORBID_WEAK_KEYS.

IV cannot be on stack when CONFIG_VMAP_STACK is selected because the stack

Remove dead code related to internal IV generators, which are no longer
used since they've been replaced with the "seqiv" and "echainiv"
templates. The removed code includes:
- The "givcipher" (GIVCIPHER) algorithm type. No algorithms are
registered with this type anymore, so it's unneeded.
- The "const char *geniv" member of aead_alg, ablkcipher_alg, and
blkcipher_alg. A few algorithms still set this, but it isn't used
anymore except to show via /proc/crypto and CRYPTO_MSG_GETALG.
Just hardcode "<default>" or "<none>" in those cases.
- The 'skcipher_givcrypt_request' structure, which is never used.

Some ahash algorithms set .cra_type = &crypto_ahash_type. But this is
redundant with the C structure type ('struct ahash_alg'), and
crypto_register_ahash() already sets the .cra_type automatically.
Apparently the useless assignment has just been copy+pasted around.
So, remove the useless assignment from all the ahash algorithms.
This patch shouldn't change any actual behavior.

The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:
devm_kzalloc(handle, a * b, gfp)
with:
devm_kcalloc(handle, a * b, gfp)
as well as handling cases of:
devm_kzalloc(handle, a * b * c, gfp)
with:
devm_kzalloc(handle, array3_size(a, b, c), gfp)
as it's slightly less ugly than:
devm_kcalloc(handle, array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
devm_kzalloc(handle, 4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".
The Coccinelle script used for this was:

Commit 49f9783b0cea ("crypto: talitos - do hw_context DMA mapping

req_ctx->hw_context
Commit 37b5e8897eb5 ("crypto: talitos - chain in buffered data for ahash
on SEC1") introduced a persistent dma mapping of req_ctx->buf
As there is no destructor for req_ctx (the request context), the
associated dma handlers where set in ctx (the tfm context). This is
wrong as several hash operations can run with the same ctx.
This patch removes this persistent mapping.

The talitos driver starts several async crypto ops and waits for their
completions. Move it over to generic code doing the same.

SEC1 doesn't support S/G in descriptors so for hash operations,
the CPU has to build a buffer containing the buffered block and
the incoming data. This generates a lot of memory copies which
represents more than 50% of CPU time of a md5sum operation as
shown below with a 'perf record'.

| | | | | | | | | | | |
| | | | | | | | | | | |--55.29%-- memcpy
| | | | | | | | | | | |
However, unlike SEC2+, SEC1 offers the possibility to chain
descriptors. It is therefore possible to build a first descriptor
pointing to the buffered data and a second descriptor pointing to
the incoming data, hence avoiding the memory copy to a single
buffer.
With this patch, the time necessary for a md5sum on a 90Mbytes file
is approximately 3 seconds. Without the patch it takes 6 seconds.

dma_map_single() is an heavy operation which doesn't need to

This patch zeroize the descriptor at allocation using memset().
This has two advantages:
- It reduces the number of places where data has to be set to 0
- It avoids reading memory and loading the cache with data that
will be entirely replaced.

This is due to SHA224 not being supported by the HW. Allthough for
hash we are able to init the hash context by SW, it is not
possible for AEAD. Therefore SHA224 AEAD has to be deactivated.

Today, md5sum fails with error -ENOKEY because a setkey
function is set for non hmac hashing algs, see strace output below:
mmap(NULL, 378880, PROT_READ, MAP_SHARED, 6, 0) = 0x77f50000
accept(3, 0, NULL) = 7
vmsplice(5, [{"bin/\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0"..., 378880}], 1, SPLICE_F_MORE|SPLICE_F_GIFT) = 262144
splice(4, NULL, 7, NULL, 262144, SPLICE_F_MORE) = -1 ENOKEY (Required key not available)
write(2, "Generation of hash for file kcap"..., 50) = 50
munmap(0x77f50000, 378880) = 0
This patch ensures that setkey() function is set only
for hmac hashing.

An updated patch that also handles the additional key length requirements
for the AEAD algorithms.
The max keysize is not 96. For SHA384/512 it's 128, and for the AEAD
algorithms it's longer still. Extend the max keysize for the
AEAD size for AES256 + HMAC(SHA512).

SEC1 doesn't have IPSEC_ESP descriptor type but it is able to perform
IPSEC using HMAC_SNOOP_NO_AFEU, which is also existing on SEC2
In order to be able to define descriptors templates for SEC1 without
breaking SEC2+, we have to give lower priority to HMAC_SNOOP_NO_AFEU
so that SEC2+ selects IPSEC_ESP and not HMAC_SNOOP_NO_AFEU which is
less performant.
This is done by adding a priority field in the template. If the field
is 0, we use the default priority, otherwise we used the one in the
field.

This patchs enhances the IPSEC_ESP related functions for them to
also supports the same operations with descriptor type
HMAC_SNOOP_NO_AFEU.
The differences between the two descriptor types are:
* pointeurs 2 and 3 are swaped (Confidentiality key and
Primary EU Context IN)
* HMAC_SNOOP_NO_AFEU has CICV out in pointer 6
* HMAC_SNOOP_NO_AFEU has no primary EU context out so we get it
from the end of data out

In preparation of IPSEC for SEC1, first step is to make the mapping
helpers more generic so that they can also be used by AEAD functions.
First, the functions are moved before IPSEC functions in talitos.c
talitos_sg_unmap() and unmap_sg_talitos_ptr() are merged as they
are quite similar, the second one handling the SEC1 case an calling
the first one for SEC2
map_sg_in_talitos_ptr() and map_sg_out_talitos_ptr() are merged
into talitos_sg_map() and enhenced to support offseted zones
as used for AEAD. The actual mapping is now performed outside that
helper. The DMA sync is also done outside to not make it several
times.
talitos_edesc_alloc() size calculation are fixed to also take into
account AEAD specific parts also for SEC1

Fix them by providing the correct cipher in & cipher out pointers,
i.e. must skip over associated data in src and dst S/G.
While here, fix a problem with the HW S/G table index usage:
tbl_off must be updated after the pointer to the table entries is set.
