2008-01-26[CRYPTO] hifn795x: Disallow built-in hifn795x when HW_RANDOM is mHerbert Xu2-4/+10
Currently it is possible to select HW_RANDOM as a module and have hifn795x built-in. This causes a build problem because hifn795x will then call hwrng_register which isn't built-in.

2008-01-11[CRYPTO] blkcipher: Merge ablkcipher and blkcipher into one option/moduleHerbert Xu1-1/+1
With the impending addition of the givcipher type, both blkcipher and ablkcipher algorithms will use it to create givcipher objects. As such it no longer makes sense to split the system between ablkcipher and blkcipher. In particular, both ablkcipher.c and blkcipher.c would need to use the givcipher type which has to reside in ablkcipher.c since it shares much code with it.

2008-01-11[HIFN]: Improve PLL initializationPatrick McHardy1-2/+108
The current PLL initalization has a number of deficiencies: - uses fixed multiplier of 8, which overclocks the chip when using a reference clock that operates at frequencies above 33MHz. According to a comment in the BSD source, this is true for the external clock on almost all every board. - writes to a reserved bit - doesn't follow the initialization procedure specified in chapter 6.11.1 of the HIFN hardware users guide - doesn't allow to use the PCI clock This patch adds a module parameter to specify the reference clock (pci or external) and its frequency and uses that to calculate the optimum multiplier to reach the maximal speed. By default it uses the external clock and assumes a speed of 66MHz, which effectively halfs the frequency currently used.

2008-01-11[CRYPTO] ablkcipher: Add distinct ABLKCIPHER typeHerbert Xu1-1/+1
Up until now we have ablkcipher algorithms have been identified as type BLKCIPHER with the ASYNC bit set. This is suboptimal because ablkcipher refers to two things. On the one hand it refers to the top-level ablkcipher interface with requests. On the other hand it refers to and algorithm type underneath. As it is you cannot request a synchronous block cipher algorithm with the ablkcipher interface on top. This is a problem because we want to be able to eventually phase out the blkcipher top-level interface. This patch fixes this by making ABLKCIPHER its own type, just as we have distinct types for HASH and DIGEST. The type it associated with the algorithm implementation only. Which top-level interface is used for synchronous block ciphers is then determined by the mask that's used. If it's a specific mask then the old blkcipher interface is given, otherwise we go with the new ablkcipher interface. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This patch forces HIFN driver to invoke crypto request callbacks from tasklet (softirq context) instead of hardirq context, since network stack expects it to be called from bottom halves. It is done by simply scheduling callback invocation via dedicated tasklet.

2007-02-14[PATCH] remove many unneeded #includes of sched.hTim Schmielau1-1/+0
After Al Viro (finally) succeeded in removing the sched.h #include in module.h recently, it makes sense again to remove other superfluous sched.h includes. There are quite a lot of files which include it but don't actually need anything defined in there. Presumably these includes were once needed for macros that used to live in sched.h, but moved to other header files in the course of cleaning it up. To ease the pain, this time I did not fiddle with any header files and only removed #includes from .c-files, which tend to cause less trouble. Compile tested against 2.6.20-rc2 and 2.6.20-rc2-mm2 (with offsets) on alpha, arm, i386, ia64, mips, powerpc, and x86_64 with allnoconfig, defconfig, allmodconfig, and allyesconfig as well as a few randconfigs on x86_64 and all configs in arch/arm/configs on arm. I also checked that no new warnings were introduced by the patch (actually, some warnings are removed that were emitted by unnecessarily included header files).
