* | crypto: cbc - Convert to skcipherHerbert Xu2016-11-281-104/+138
| | | | | | | | | | | | | | This patch converts cbc over to the skcipher interface. It also rearranges the code to allow it to be reused by drivers. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* | crypto: arm64/aes - Convert to skcipherHerbert Xu2016-11-281-224/+158

* | crypto: aesni - Convert to skcipherHerbert Xu2016-11-283-573/+346
| | | | | | | | | | | | | | | | | | This patch converts aesni (including fpu) over to the skcipher interface. The LRW implementation has been removed as the generic LRW code can now be used directly on top of the accelerated ECB implementation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* | crypto: testmgr - Do not test internal algorithmsHerbert Xu2016-11-282-150/+11
| | | | | | | | | | | | | | | | | | | | | | | | Currently we manually filter out internal algorithms using a list in testmgr. This is dangerous as internal algorithms cannot be safely used even by testmgr. This patch ensures that they're never processed by testmgr at all. This patch also removes an obsolete bypass for nivciphers which no longer exist. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* | crypto: glue_helper - Add skcipher xts helpersHerbert Xu2016-11-283-3/+112
| | | | | | | | | | | | | | This patch adds xts helpers that use the skcipher interface rather than blkcipher. This will be used by aesni_intel. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* | crypto: simd - Add simd skcipher helperHerbert Xu2016-11-284-0/+249
| | | | | | | | | | | | | | | | | | This patch adds the simd skcipher helper which is meant to be a replacement for ablk helper. It replaces the underlying blkcipher interface with skcipher, and also presents the top-level algorithm as an skcipher. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* | crypto: api - Do not clear type bits in crypto_larval_lookupHerbert Xu2016-11-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | Currently all bits not set in mask are cleared in crypto_larval_lookup. This is unnecessary as wherever the type bits are used it is always masked anyway. This patch removes the clearing so that we may use bits set in the type but not in the mask for special purposes, e.g., picking up internal algorithms.

* | crypto: xts - Convert to skcipherHerbert Xu2016-11-282-157/+416
| | | | | | | | | | | | | | | | | | | | This patch converts xts over to the skcipher interface. It also optimises the implementation to be based on ECB instead of the underlying cipher. For compatibility the existing naming scheme of xts(aes) is maintained as opposed to the more obvious one of xts(ecb(aes)). Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

The version in this patch was taken from OpenSSL commit 32bbb62ea634 ("sha/asm/sha512-armv8.pl: fix big-endian support in __KERNEL__ case.") * The core SHA algorithm is fundamentally sequential, but there is a secondary transformation involved, called the schedule update, which can be performed independently. The NEON version of SHA-224/SHA-256 only implements this part of the algorithm using NEON instructions, the sequential part is always done using scalar instructions.

* | crypto: drbg - advance output buffer pointerStephan Mueller2016-11-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The CTR DRBG segments the number of random bytes to be generated into 128 byte blocks. The current code misses the advancement of the output buffer pointer when the requestor asks for more than 128 bytes of data. In this case, the next 128 byte block of random numbers is copied to the beginning of the output buffer again. This implies that only the first 128 bytes of the output buffer would ever be filled. The patch adds the advancement of the buffer pointer to fill the entire buffer. Signed-off-by: Stephan Mueller <smueller@chronox.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Quoting from Russell's findings: https://www.mail-archive.com/linux-crypto@vger.kernel.org/msg21136.html [quote] Okay, I've re-tested, using a different way of measuring, because using openssl speed is impractical for off-loaded engines. I've decided to use this way to measure the performance: dd if=/dev/zero bs=1048576 count=128 | /usr/bin/time openssl dgst -md5 For the threaded IRQs case gives: 0.05user 2.74system 0:05.30elapsed 52%CPU (0avgtext+0avgdata 2400maxresident)k 0.06user 2.52system 0:05.18elapsed 49%CPU (0avgtext+0avgdata 2404maxresident)k 0.12user 2.60system 0:05.61elapsed 48%CPU (0avgtext+0avgdata 2460maxresident)k => 5.36s => 25.0MB/s and the tasklet case: 0.08user 2.53system 0:04.83elapsed 54%CPU (0avgtext+0avgdata 2468maxresident)k 0.09user 2.47system 0:05.16elapsed 49%CPU (0avgtext+0avgdata 2368maxresident)k 0.10user 2.51system 0:04.87elapsed 53%CPU (0avgtext+0avgdata 2460maxresident)k => 4.95 => 27.1MB/s which corresponds to an 8% slowdown for the threaded IRQ case. So, tasklets are indeed faster than threaded IRQs. [...] I think I've proven from the above that this patch needs to be reverted due to the performance regression, and that there _is_ most definitely a deterimental effect of switching from tasklets to threaded IRQs.

* | crypto: caam - fix AEAD givenc descriptorsAlex Porosanu2016-11-131-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The AEAD givenc descriptor relies on moving the IV through the output FIFO and then back to the CTX2 for authentication. The SEQ FIFO STORE could be scheduled before the data can be read from OFIFO, especially since the SEQ FIFO LOAD needs to wait for the SEQ FIFO LOAD SKIP to finish first. The SKIP takes more time when the input is SG than when it's a contiguous buffer. If the SEQ FIFO LOAD is not scheduled before the STORE, the DECO will hang waiting for data to be available in the OFIFO so it can be transferred to C2. In order to overcome this, first force transfer of IV to C2 by starting the "cryptlen" transfer first and then starting to store data from OFIFO to the output buffer.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The exponent size in the ccp_op structure is in bits. A v5 CCP requires the exponent size to be in bytes, so convert the size from bits to bytes when populating the descriptor. The current code references the exponent in memory, but these fields have not been set since the exponent is actually store in the LSB. Populate the descriptor with the LSB location (address).
