[CRYPTO] xcbc: Fix crash when ipsec uses xcbc-mac with big data chunk

2008-04-02T06:36:09Z

The kernel crashes when ipsec passes a udp packet of about 14XX bytes of data to aes-xcbc-mac. It seems the first xxxx bytes of the data are in first sg entry, and remaining xx bytes are in next sg entry. But we don't check next sg entry to see if we need to go look the page up. I noticed in hmac.c, we do a scatterwalk_sg_next(), to do this check and possible lookup, thus xcbc.c needs to use this routine too. A 15-hour run of an ipsec stress test sending streams of tcp and udp packets of various sizes, using this patch and aes-xcbc-mac completed successfully, so hopefully this fixes the problem.

async_tx: avoid the async xor_zero_sum path when src_cnt > device->max_xor

2008-03-19T00:01:00Z

If the channel cannot perform the operation in one call to ->device_prep_dma_zero_sum, then fallback to the xor+page_is_zero path. This only affects users with arrays larger than 16 devices on iop13xx or 32 devices on iop3xx. Cc: Cc: Neil Brown Signed-off-by: Dan Williams

[CRYPTO] skcipher: Fix section mismatches

2008-03-08T12:29:43Z

The previous patch to move chainiv and eseqiv into blkcipher created a section mismatch for the chainiv exit function which was also called from __init. This patch removes the __exit marking on it. Signed-off-by: Herbert Xu

[CRYPTO] xcbc: Fix crash with IPsec

2008-03-06T11:28:44Z

When using aes-xcbc-mac for authentication in IPsec, the kernel crashes. It seems this algorithm doesn't account for the space IPsec may make in scatterlist for authtag. Thus when crypto_xcbc_digest_update2() gets called, nbytes may be less than sg[i].length. Since nbytes is an unsigned number, it wraps at the end of the loop allowing us to go back into loop and causing crash in memcpy. I used update function in digest.c to model this fix. Please let me know if it looks ok. Signed-off-by: Joy Latten Signed-off-by: Herbert Xu

[CRYPTO] xts: Use proper alignment

2008-03-06T10:56:19Z

The XTS blockmode uses a copy of the IV which is saved on the stack and may or may not be properly aligned. If it is not, it will break hardware cipher like the geode or padlock. This patch encrypts the IV in place so we don't have to worry about alignment. Signed-off-by: Sebastian Siewior Tested-by: Stefan Hellermann Signed-off-by: Herbert Xu

[CRYPTO] digest: Include internal.h for prototypes

2008-03-05T11:05:54Z

Every file should include the headers containing the externs for its global code (in this case for struct crypto_{init,exit}_digest_ops()). Signed-off-by: Adrian Bunk Signed-off-by: Herbert Xu

[CRYPTO] authenc: Add missing Kconfig dependency on BLKCIPHER

[CRYPTO] skcipher: Move chainiv/seqiv into crypto_blkcipher module

2008-02-23T03:12:06Z

For compatibility with dm-crypt initramfs setups it is useful to merge chainiv/seqiv into the crypto_blkcipher module. Since they're required by most algorithms anyway this is an acceptable trade-off. Signed-off-by: Herbert Xu
