crypto: padlock - Fix AES-CBC handling on odd-block-sized input

2010-12-09T21:27:10Z

commit c054a076a1bd4731820a9c4d638b13d5c9bf5935 upstream. On certain VIA chipsets AES-CBC requires the input/output to be a multiple of 64 bytes. We had a workaround for this but it was buggy as it sent the whole input for processing when it is meant to only send the initial number of blocks which makes the rest a multiple of 64 bytes. As expected this causes memory corruption whenever the workaround kicks in. Reported-by: Phil Sutter Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman

crypto: padlock-sha - Add import/export support

2010-02-23T15:37:54Z

commit a8d7ac279743077965afeca0c9ed748507b68e89 upstream. As the padlock driver for SHA uses a software fallback to perform partial hashing, it must implement custom import/export functions. Otherwise hmac which depends on import/export for prehashing will not work with padlock-sha. Reported-by: Wolfgang Walter Signed-off-by: Herbert Xu Signed-off-by: Greg Kroah-Hartman

crypto: padlock-aes - Use the correct mask when checking whether copying is required

2009-11-03T15:32:03Z

Masking with PAGE_SIZE is just wrong... Signed-off-by: Chuck Ebbert Signed-off-by: Herbert Xu

crypto: padlock-sha - Fix stack alignment

2009-09-22T06:21:53Z

The PadLock hardware requires the output buffer for SHA to be 128-bit aligned. We currentply place the buffer on the stack, and ask gcc to align it to 128 bits. That doesn't work on i386 because the kernel stack is only aligned to 32 bits. This patch changes the code to align the buffer by hand so that the hardware doesn't fault on unaligned buffers.

crypto: talitos - add support for 36 bit addressing

2009-08-13T01:51:51Z

Enabling extended addressing in the h/w requires we always assign the extended address component (eptr) of the talitos h/w pointer. This is for e500 based platforms with large memories. Signed-off-by: Kim Phillips Signed-off-by: Herbert Xu

crypto: talitos - align locks on cache lines

2009-08-13T01:50:38Z

align channel access locks onto separate cache lines (for performance reasons). This is done by placing per-channel variables into their own private struct, and using the cacheline_aligned attribute within that struct. Signed-off-by: Kim Phillips Signed-off-by: Herbert Xu

crypto: talitos - simplify hmac data size calculation

2009-08-13T01:49:06Z

don't do request->src vs. assoc pointer math - it's the same as adding assoclen and ivsize (just with more effort). Signed-off-by: Kim Phillips Signed-off-by: Herbert Xu

crypto: mv_cesa - Add support for Orion5X crypto engine

2009-08-10T02:50:03Z

This adds support for Marvell's Cryptographic Engines and Security Accelerator (CESA) which can be found on a few SoC. Tested with dm-crypt. Acked-by: Nicolas Pitre Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Herbert Xu

crypto: padlock - Fix hashing of partial blocks

2009-07-16T02:33:27Z

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

crypto: padlock - Fix compile error on i386

2009-07-15T10:37:48Z

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
