Patch 8d916bd45dfc5eaa992617028c3d796d8d81cd8a added NULL entries for intel accelerated drivers but did not marked these fips allowed. This cause panic if running tests with fips=1.

2012-06-29netlink: add netlink_kernel_cfg parameter to netlink_kernel_createPablo Neira Ayuso1-2/+5
This patch adds the following structure: struct netlink_kernel_cfg { unsigned int groups; void (*input)(struct sk_buff *skb); struct mutex *cb_mutex; }; That can be passed to netlink_kernel_create to set optional configurations for netlink kernel sockets. I've populated this structure by looking for NULL and zero parameters at the existing code. The remaining parameters that always need to be set are still left in the original interface. That includes optional parameters for the netlink socket creation. This allows easy extensibility of this interface in the future. This patch also adapts all callers to use this new interface.

2012-06-22crypto: algapi - Move larval completion into algbossHerbert Xu3-26/+9
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: Herbert Xu <herbert@gondor.apana.org.au>

2012-06-12crypto: serpent - add x86_64/avx assembler implementationJohannes Goetzfried2-0/+80
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.

2012-06-12crypto: twofish - add x86_64/avx assembler implementationJohannes Goetzfried3-0/+107
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.

2012-03-14crypto: camellia - simplify key setup and CAMELLIA_ROUNDSM macroJussi Kivilinna1-21/+3
camellia_setup_tail() applies 'inverse of the last half of P-function' to subkeys, which is unneeded if keys are applied directly to yl/yr in CAMELLIA_ROUNDSM. Patch speeds up key setup and should speed up CAMELLIA_ROUNDSM as applying key to yl/yr early has less register dependencies.

2012-02-16crypto: sha512 - use standard ror64()Alexey Dobriyan1-9/+4
Use standard ror64() instead of hand-written. There is no standard ror64, so create it. The difference is shift value being "unsigned int" instead of uint64_t (for which there is no reason). gcc starts to emit native ROR instructions which it doesn't do for some reason currently. This should make the code faster. Patch survives in-tree crypto test and ping flood with hmac(sha512) on.

2012-02-05crypto: In crypto_add_alg(), 'exact' wants to be initialized to 0Jesper Juhl1-1/+1
We declare 'exact' without initializing it and then do: [...] if (strlen(p->cru_driver_name)) exact = 1; if (priority && !exact) return -EINVAL; [...] If the first 'if' is not true, then the second will test an uninitialized 'exact'. As far as I can tell, what we want is for 'exact' to be initialized to 0 (zero/false).

2012-02-05crypto: sha512 - Avoid stack bloat on i386Herbert Xu1-36/+32
Unfortunately in reducing W from 80 to 16 we ended up unrolling the loop twice. As gcc has issues dealing with 64-bit ops on i386 this means that we end up using even more stack space (>1K). This patch solves the W reduction by moving LOAD_OP/BLEND_OP into the loop itself, thus avoiding the need to duplicate it. While the stack space still isn't great (>0.5K) it is at least in the same ball park as the amount of stack used for our C sha1 implementation. Note that this patch basically reverts to the original code so the diff looks bigger than it really is. Cc: stable@vger.kernel.org Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
