2012-04-05crypto: sha512 - Fix byte counter overflow in SHA-512Kent Yoder
The current code only increments the upper 64 bits of the SHA-512 byte counter when the number of bytes hashed happens to hit 2^64 exactly. This patch increments the upper 64 bits whenever the lower 64 bits overflows.

2012-03-29crypto: user - Fix size of netlink dump messageSteffen Klassert
The default netlink message size limit might be exceeded when dumping a lot of algorithms to userspace. As a result, not all of the instantiated algorithms dumped to userspace. So calculate an upper bound on the message size and call netlink_dump_start() with that value.

2012-03-29crypto: user - Fix lookup of algorithms with IV generatorSteffen Klassert
We lookup algorithms with crypto_alg_mod_lookup() when instantiating via crypto_add_alg(). However, algorithms that are wrapped by an IV genearator (e.g. aead or genicv type algorithms) need special care. The userspace process hangs until it gets a timeout when we use crypto_alg_mod_lookup() to lookup these algorithms. So export the lookup functions for these algorithms and use them in crypto_add_alg().

2012-03-29crypto: pcrypt - Use the online cpumask as the defaultSteffen Klassert
We use the active cpumask to determine the superset of cpus to use for parallelization. However, the active cpumask is for internal usage of the scheduler and therefore not the appropriate cpumask for these purposes. So use the online cpumask instead.

2012-03-14crypto: camellia - add assembler implementation for x86_64Jussi Kivilinna
Patch adds x86_64 assembler implementation of Camellia block cipher. Two set of functions are provided. First set is regular 'one-block at time' encrypt/decrypt functions. Second is 'two-block at time' functions that gain performance increase on out-of-order CPUs. Performance of 2-way functions should be equal to 1-way functions with in-order CPUs. Patch has been tested with tcrypt and automated filesystem tests.

This updates the sha512 fix so that it doesn't cause excessive stack usage on i386. This is done by reverting to the original code, and avoiding the W duplication by moving its initialisation into the loop. As the underlying code is in fact the one that we have used for years, I'm pushing this now instead of postponing to the next cycle. * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: crypto: sha512 - Avoid stack bloat on i386 crypto: sha512 - Use binary and instead of modulus

2012-02-05crypto: sha512 - Avoid stack bloat on i386Herbert Xu
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>

2012-01-15crypto: sha512 - reduce stack usage to safe numberAlexey Dobriyan
For rounds 16--79, W[i] only depends on W[i - 2], W[i - 7], W[i - 15] and W[i - 16]. Consequently, keeping all W[80] array on stack is unnecessary, only 16 values are really needed. Using W[16] instead of W[80] greatly reduces stack usage (~750 bytes to ~340 bytes on x86_64). Line by line explanation: * BLEND_OP array is "circular" now, all indexes have to be modulo 16. Round number is positive, so remainder operation should be without surprises. * initial full message scheduling is trimmed to first 16 values which come from data block, the rest is calculated before it's needed. * original loop body is unrolled version of new SHA512_0_15 and SHA512_16_79 macros, unrolling was done to not do explicit variable renaming. Otherwise it's the very same code after preprocessing. See sha1_transform() code which does the same trick. Patch survives in-tree crypto test and original bugreport test (ping flood with hmac(sha512).

If sha512_update will ever be entered twice, hash will be silently calculated incorrectly. Probably the easiest way to notice incorrect hashes being calculated is to run 2 ping floods over AH with hmac(sha512): #!/usr/sbin/setkey -f flush; spdflush; add IP1 IP2 ah 25 -A hmac-sha512 0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000025; add IP2 IP1 ah 52 -A hmac-sha512 0x00000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000052; spdadd IP1 IP2 any -P out ipsec ah/transport//require; spdadd IP2 IP1 any -P in ipsec ah/transport//require; XfrmInStateProtoError will start ticking with -EBADMSG being returned from ah_input(). This never happens with, say, hmac(sha1). With patch applied (on BOTH sides), XfrmInStateProtoError does not tick with multiple bidirectional ping flood streams like it doesn't tick with SHA-1. After this patch sha512_transform() will start using ~750 bytes of stack on x86_64. This is OK for simple loads, for something more heavy, stack reduction will be done separatedly.

2011-12-20crypto: serpent-sse2 - select LRW and XTSJussi Kivilinna
serpent-sse2 uses functions from LRW and XTS modules, so selecting would appear to be better option than using #ifdefs in serpent_sse2_glue.c to enable/disable LRW and XTS features. This also fixes build problem when serpent-sse2 would be build into kernel but XTS/LRW are build as modules.

2011-11-21crypto: serpent - add 8-way parallel x86_64/SSE2 assembler implementationJussi Kivilinna
Patch adds x86_64/SSE2 assembler implementation of serpent cipher. Assembler functions crypt data in eigth block chunks (two 4 block chunk SSE2 operations in parallel to improve performance on out-of-order CPUs). Glue code is based on one from AES-NI implementation, so requests from irq context are redirected to cryptd. v2: - add missing include of linux/module.h (appearently crypto.h used to include module.h, which changed for 3.2 by commit 7c926402a7e8c9b279968fd94efec8700ba3859e) Patch has been tested with tcrypt and automated filesystem tests.

Therefore we introduce crypto_unregister_instance() to unlink the crypto instance from the template's instances list and to free the recources of the instance properly.
