2012-03-21Merge branch 'kmap_atomic' of git://github.com/congwang/linuxLinus Torvalds6-20/+20
Pull kmap_atomic cleanup from Cong Wang. It's been in -next for a long time, and it gets rid of the (no longer used) second argument to k[un]map_atomic(). Fix up a few trivial conflicts in various drivers, and do an "evil merge" to catch some new uses that have come in since Cong's tree. * 'kmap_atomic' of git://github.com/congwang/linux: (59 commits) feature-removal-schedule.txt: schedule the deprecated form of kmap_atomic() for removal highmem: kill all __kmap_atomic() [swarren@nvidia.com: highmem: Fix ARM build break due to __kmap_atomic rename] drbd: remove the second argument of k[un]map_atomic() zcache: remove the second argument of k[un]map_atomic() gma500: remove the second argument of k[un]map_atomic() dm: remove the second argument of k[un]map_atomic() tomoyo: remove the second argument of k[un]map_atomic() sunrpc: remove the second argument of k[un]map_atomic() rds: remove the second argument of k[un]map_atomic() net: remove the second argument of k[un]map_atomic() mm: remove the second argument of k[un]map_atomic() lib: remove the second argument of k[un]map_atomic() power: remove the second argument of k[un]map_atomic() kdb: remove the second argument of k[un]map_atomic() udf: remove the second argument of k[un]map_atomic() ubifs: remove the second argument of k[un]map_atomic() squashfs: remove the second argument of k[un]map_atomic() reiserfs: remove the second argument of k[un]map_atomic() ocfs2: remove the second argument of k[un]map_atomic() ntfs: remove the second argument of k[un]map_atomic() ...

Davem considers that the argument list of this interface is getting out of control.

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.

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 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>
2012-01-26crypto: sha512 - Use binary and instead of modulusHerbert Xu1-2/+2

2012-01-15crypto: sha512 - reduce stack usage to safe numberAlexey Dobriyan1-24/+34
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).

2012-01-15crypto: sha512 - make it work, undo percpu message scheduleAlexey Dobriyan1-5/+1
commit f9e2bca6c22d75a289a349f869701214d63b5060 aka "crypto: sha512 - Move message schedule W[80] to static percpu area" created global message schedule area. 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.

Apparently, NIST is tightening up its requirements for FIPS validation with respect to RNGs. Its always been required that in fips mode, the ansi cprng not be fed key and seed material that was identical, but they're now interpreting FIPS 140-2, section AS07.09 as requiring that the implementation itself must enforce the requirement. Easy fix, we just do a memcmp of key and seed in fips_cprng_reset and call it a day. v2: Per Neil's advice, ensure slen is sufficiently long before we compare key and seed to avoid looking at potentially unallocated mem.

Tcrypt benchmarks results (twofish-3way/twofish-asm speed ratios): Intel Celeron T1600 (fam:6, model:15, step:13): size lrw-enc lrw-dec 16B 0.99x 1.00x 64B 1.17x 1.17x 256B 1.26x 1.27x 1024B 1.30x 1.31x 8192B 1.31x 1.32x AMD Phenom II 1055T (fam:16, model:10): size lrw-enc lrw-dec 16B 1.06x 1.01x 64B 1.08x 1.14x 256B 1.19x 1.20x 1024B 1.21x 1.22x 8192B 1.23x 1.24x Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2011-11-09crypto: serpent - rename module from serpent to serpent_genericJussi Kivilinna2-1/+6
Rename module from serpent.ko to serpent_generic.ko and add module alias. This is to allow assembler implementation to autoload on 'modprobe serpent'. Also add driver_name and priority for serpent cipher.
