init_desc, by always ORing with 1 for the descriptor header inclusion into the descriptor length, and init_sh_desc_pdb, by always specifying the descriptor length modification for the PDB via options, would not allow for odd length PDBs to be embedded in the constructed descriptor length. Fix this by simply changing the OR to an addition. also round-up pdb_bytes to the next SEC command unit size, to allow for, e.g., optional packet header bytes that aren't a multiple of CAAM_CMD_SZ.

crypto: serpent-sse2 - prepare serpent-sse2 glue code into generic x86 glue code for 128bit block ciphers Block cipher implementations in arch/x86/crypto/ contain common glue code that is currently duplicated in each module (camellia-x86_64, twofish-x86_64-3way, twofish-avx, serpent-sse2 and serpent-avx). This patch prepares serpent-sse2 glue into generic glue code for all 128bit block ciphers to use in arch/x86/crypto. Signed-off-by:

It has been observed that sometimes the crypto allocation code will get stuck for 60 seconds or multiples thereof. This is usually caused by an algorithm failing to pass the self-test. If an algorithm fails to be constructed, we will immediately notify all larval waiters. However, if it succeeds in construction, but then fails the self-test, we won't notify anyone at all. This patch fixes this by merging the notification in the case where the algorithm fails to be constructed with that of the the case where it pases the self-test. This way regardless of what happens, we'll give the larval waiters an answer. Signed-off-by:

Currently arc4.c provides simple one-byte blocksize cipher which is wrapped by ecb() module, giving function call overhead on every encrypted byte.

This patch adds a x86_64/avx assembler implementation of the Serpent block cipher. The implementation is very similar to the sse2 implementation and processes eight blocks in parallel. Because of the new non-destructive three operand syntax all move-instructions can be removed and therefore a little performance increase is provided. Patch has been tested with tcrypt and automated filesystem tests.

The AVX implementation of the twofish cipher processes 8 blocks parallel, so we need to make test vectors larger to check parallel code paths. Test vectors are also large enough to deal with 16 block parallel implementations which may occur in the future. Signed-off-by:

This patch adds a x86_64/avx assembler implementation of the Twofish block cipher. The implementation processes eight blocks in parallel (two 4 block chunk AVX operations). The table-lookups are done in general-purpose registers. For small blocksizes the 3way-parallel functions from the twofish-x86_64-3way module are called. A good performance increase is provided for blocksizes greater or equal to 128B. Patch has been tested with tcrypt and automated filesystem tests.

The CRC peripheral is a hardware block used to compute the CRC of the block of data. This is based on a CRC32 engine which computes the CRC value of 32b data words presented to it. For data words of < 32b in size, this driver pack 0 automatically into 32b data units. This driver implements the async hash crypto framework API. Signed-off-by:

If the privileges given to root threads (3% of allowable memory) or a negative value of /proc/pid/oom_score_adj happen to exceed the amount of rss of a thread, its badness score overflows as a result of commit a7f638f9 ("mm, oom: normalize oom scores to oom_score_adj scale only for userspace"). Fix this by making the type signed and return 1, meaning the thread is still eligible for kill, if the value is negative. Reported-by:
