* crypto: testmgr - make test_aead also test 'dst != src' code pathsJussi Kivilinna2012-09-271-48/+105
| | | | | | | | | | | | Currrently test_aead uses same buffer for destination and source. However in any places, 'dst != src' take different path than 'dst == src' case. Therefore make test_aead also run tests with destination buffer being different than source buffer. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Acked-by: David S.

* crypto, tcrypt: remove local_bh_disable/enable() around ↵Suresh Siddha2012-09-271-6/+0
| | | | | | | | | | | | | | | | | | | | | | | local_irq_disable/enable() Ran into this while looking at some new crypto code using FPU hitting a WARN_ON_ONCE(!irq_fpu_usable()) in the kernel_fpu_begin() on a x86 kernel that uses the new eagerfpu model. In short, current eagerfpu changes return 0 for interrupted_kernel_fpu_idle() and the in_interrupt() thinks it is in the interrupt context because of the local_bh_disable(). Thus resulting in the WARN_ON(). Remove the local_bh_disable/enable() calls around the existing local_irq_disable/enable() calls. local_irq_disable/enable() already disables the BH. [ If there are any other legitimate users calling kernel_fpu_begin() from the process context but with BH disabled, then we can look into fixing the irq_fpu_usable() in future. ] Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Cc: Tim Chen <tim.c.chen@linux.intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* powerpc/crypto: add 842 crypto driverSeth Jennings2012-08-013-0/+193
| | | | | | | | | | | | | | | | | | This patch add the 842 cryptographic API driver that submits compression requests to the 842 hardware compression accelerator driver (nx-compress). If the hardware accelerator goes offline for any reason (dynamic disable, migration, etc...), this driver will use LZO as a software failover for all future compression requests. For decompression requests, the 842 hardware driver contains a software implementation of the 842 decompressor to support the decompression of data that was compressed before the accelerator went offline.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a x86_64/avx assembler implementation of the Cast6 block cipher.

| | | | | | | | | | | | | | | | | | | | | | git commit 582802f3e (crypto: algapi - Move larval completion into algboss) replaced accidentally a call to complete_all() by a call to complete().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

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.
