This patch adds the AEAD support for AF_ALG. The implementation is based on algif_skcipher, but contains heavy modifications to streamline the interface for AEAD uses. To use AEAD, the user space consumer has to use the salg_type named "aead". The AEAD implementation includes some overhead to calculate the size of the ciphertext, because the AEAD implementation of the kernel crypto API makes implied assumption on the location of the authentication tag. When performing an encryption, the tag will be added to the created ciphertext (note, the tag is placed adjacent to the ciphertext). For decryption, the caller must hand in the ciphertext with the tag appended to the ciphertext. Therefore, the selection of the used memory needs to add/subtract the tag size from the source/destination buffers depending on the encryption type. The code is provided with comments explaining when and how that operation is performed. A fully working example using all aspects of AEAD is provided at http://www.chronox.de/libkcapi.htmlSigned-off-by: NStephan Mueller <smueller@chronox.de> Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

Glue code for crypto infrastructure. Call the assembler code where required. Disable preemption during calculation and enable SPE instructions in the kernel prior to the call. Avoid to disable preemption for too long. Take a little care about small input data. Kick out early for input chunks < 64 bytes and replace memset for context cleanup with simple loop.

This is the assembler code for SHA1 implementation with the SIMD SPE instruction set. With the enhanced instruction set we can operate on 2 32 bit words in parallel. That helps reducing the time to calculate W16-W79. For increasing performance even more the assembler function can compute hashes for more than one 64 byte input block. The state of the used SPE registers is preserved via the stack so we can run from interrupt context. There might be the case that we interrupt ourselves and push sensitive data from another context onto our stack. Clear this area in the stack afterwards to avoid information leakage. The code is endian independant. Signed-off-by: NMarkus Stockhausen <stockhausen@collogia.de> Signed-off-by: NHerbert Xu <herbert@gondor.apana.org.au>

The assembler AES encryption and decryption core routines. Implemented & optimized for big endian. Nevertheless they work on little endian too. For most efficient reuse in (higher level) block cipher routines they are implemented as "fast" call modules without any stack handling or register saving. The caller must take care of that part.

4K AES tables for big endian. To reduce the possiblity of timing attacks, the size has been cut to 8KB + 256 bytes in contrast to 16KB in the generic implementation.

This required a valid setkey and setauthsize functions to be added and also some changes to make sure that math context is not corrupted when the alg is used directly.

.. after extensive statistical analysis of my G+ polling, I've come to the inescapable conclusion that internet polls are bad. Big surprise. But "Hurr durr I'ma sheep" trounced "I like online polls" by a 62-to-38% margin, in a poll that people weren't even supposed to participate in. Who can argue with solid numbers like that? 5,796 votes from people who can't even follow the most basic directions? In contrast, "v4.0" beat out "v3.20" by a slimmer margin of 56-to-44%, but with a total of 29,110 votes right now. Now, arguably, that vote spread is only about 3,200 votes, which is less than the almost six thousand votes that the "please ignore" poll got, so it could be considered noise. But hey, I asked, so I'll honor the votes.
