2019-07-03crypto: arm64/aes-ce - implement 5 way interleave for ECB, CBC and CTRArd Biesheuvel
This implements 5-way interleaving for ECB, CBC decryption and CTR, resulting in a speedup of ~11% on Marvell ThunderX2, which has a very deep pipeline and therefore a high issue latency for NEON instructions operating on the same registers. Note that XTS is left alone: implementing 5-way interleave there would either involve spilling of the calculated tweaks to the stack, or recalculating them after the encryption operation, and doing either of those would most likely penalize low end cores. For ECB, this is not a concern at all, given that we have plenty of spare registers. For CTR and CBC decryption, we take advantage of the fact that v16 is not used by the CE version of the code (which is the only one targeted by the optimization), and so we can reshuffle the code a bit and avoid having to spill to memory (with the exception of one extra reload in the CBC routine) Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Fix it by: - Moving the second descriptor after the buffer, as moving the buffer after the descriptor would make it more complex for other cipher operations (AEAD, ABLKCIPHER) - Skip the bytes taken from the new request to complete the previous one by moving the SG list forward.

2019-07-03lib/scatterlist: Fix mapping iterator when sg->offset is greater than PAGE_SIZEChristophe Leroy
All mapping iterator logic is based on the assumption that sg->offset is always lower than PAGE_SIZE. But there are situations where sg->offset is such that the SG item is on the second page. In that case sg_copy_to_buffer() fails properly copying the data into the buffer. One of the reason is that the data will be outside the kmapped area used to access that data. This patch fixes the issue by adjusting the mapping iterator offset and pgoffset fields such that offset is always lower than PAGE_SIZE.

2019-06-20crypto: caam - use len instead of nents for bulding HW S/G tableHoria Geantă
Currently, conversion of SW S/G table into HW S/G layout relies on nents returned by sg_nents_for_len(sg, len). However this leaves the possibility of HW S/G referencing more data then needed: since buffer length in HW S/G entries is filled using sg_dma_len(sg), the last entry in HW S/G table might have a length that is bigger than needed for the crypto request. This way of S/G table conversion is fine, unless after converting a table more entries have to be appended to the HW S/G table. In this case, crypto engine would access data from the S/G entry having the incorrect length, instead of advancing in the S/G table. This situation doesn't exist, but the upcoming implementation of IV update for skcipher algorithms needs to add a S/G entry after req->dst S/G (corresponding to output IV).

One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct qat_alg_buf_list { ... struct qat_alg_buf bufers[]; } __packed __aligned(64); Make use of the struct_size() helper instead of an open-coded version in order to avoid any potential type mistakes. So, replace the following form: sizeof(struct qat_alg_buf_list) + ((1 + n) * sizeof(struct qat_alg_buf)) with: struct_size(bufl, bufers, n + 1) This code was detected with the help of Coccinelle.

Constify the ctx and iv arguments to crypto_chacha_init() and the various chacha*_stream_xor() functions. This makes it clear that they are not modified.

2019-06-13crypto: chacha20poly1305 - a few cleanupsEric Biggers
- Use sg_init_one() instead of sg_init_table() then sg_set_buf(). - Remove unneeded calls to sg_init_table() prior to scatterwalk_ffwd(). - Simplify initializing the poly tail block. - Simplify computing padlen. This doesn't change any actual behavior. Cc: Martin Willi <martin@strongswan.org> Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2019-06-13crypto: skcipher - make chunksize and walksize accessors internalEric Biggers
The 'chunksize' and 'walksize' properties of skcipher algorithms are implementation details that users of the skcipher API should not be looking at. So move their accessor functions from <crypto/skcipher.h> to <crypto/internal/skcipher.h>.
