| * crypto: talitos - add support for sha224Kim Phillips2010-05-192-10/+75
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SEC h/w versions 2.1 and above support sha224 via explicit instruction. Performing sha224 ahashes on earlier versions is still possible because they support sha256 (sha224 is sha256 with different initial constants and a different truncation length). We do this by overriding hardware context self-initialization, and perform it manually in s/w instead. Thanks to Lee for his fixes for correct execution on actual sec2.0 h/w.

* | | of: Remove duplicate fields from of_platform_driverGrant Likely2010-05-222-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.

* | include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-305-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* crypto: padlock - Fix hashing of partial blocksHerbert Xu2009-07-161-0/+2
| | | | | | | | When we encounter partial blocks in finup, we'll invoke the xsha instruction with a bogus count that is not a multiple of the block size. This patch fixes it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: padlock - Fix compile error on i386Herbert Xu2009-07-151-2/+4
| | | | | | | | | | The previous change to allow hashing from states other than the initial broke compilation on i386 because the inline assembly tried to squeeze a u64 into a 32-bit register. As we've already checked for 32-bit overflows we can simply truncate it to u32, or unsigned long so that we don't truncate at all on x86-64. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: crypto4xx - Disable SHA implementationHerbert Xu2009-07-151-19/+0
| | | | | | | | | | The crypto4xx SHA implementation keeps the hash state in the tfm data structure. This breaks a fundamental requirement of ahash implementations that they must be reentrant. This patch disables the broken implementation. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: crypto4xx - Switch to new style ahashHerbert Xu2009-07-142-39/+71
| | | | | | | | | | | | This patch changes crypto4xx to use the new style ahash type. In particular, we now use ahash_alg to define ahash algorithms instead of crypto_alg. This is achieved by introducing a union that encapsulates the new type and the existing crypto_alg structure. They're told apart through a u32 field containing the type value.

* crypto: crypto4xx - Use crypto_ahash_set_reqsizeHerbert Xu2009-07-142-2/+4
| | | | | | | This patch makes crypto4xx use crypto_ahash_set_reqsize to avoid accessing crypto_ahash directly. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: padlock - Switch sha to shashHerbert Xu2009-07-142-179/+156
| | | | | | | | | | | | | | | | | | | This patch converts the padlock-sha implementation to shash. In doing so the existing mechanism of storing the data until final is no longer viable as we do not have a way of allocating data in crypto_shash_init and then reliably freeing it. This is just as well because a better way of handling the problem is to hash everything but the last chunk using normal sha code and then provide the intermediate result to the padlock device. This is good enough because the primary application of padlock-sha is IPsec and there the data is laid out in the form of an hmac header followed by the rest of the packet. In essence we can provide all the data to the padlock as the hmac header only needs to be hashed once. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: padlock - Use shash fallback for shaHerbert Xu2009-07-111-30/+52

* crypto: padlock-aes - work around Nano CPU errata in CBC modeChuck Ebbert2009-06-181-18/+65

* crypto: padlock-aes - work around Nano CPU errata in ECB modeChuck Ebbert2009-06-181-35/+46
| | | | | | | | | | | The VIA Nano processor has a bug that makes it prefetch extra data during encryption operations, causing spurious page faults. Extend existing workarounds for ECB mode to copy the data to an temporary buffer to avoid the problem.
