2008-05-19rcu: split list.h and move rcu-protected lists into rculist.hFranck Bui-Huu
Move rcu-protected lists from list.h into a new header file rculist.h. This is done because list are a very used primitive structure all over the kernel and it's currently impossible to include other header files in this list.h without creating some circular dependencies. For example, list.h implements rcu-protected list and uses rcu_dereference() without including rcupdate.h. It actually compiles because users of rcu_dereference() are macros. Others RCU functions could be used too but aren't probably because of this. Therefore this patch creates rculist.h which includes rcupdates without to many changes/troubles.

2008-05-07[CRYPTO] hmac: Avoid calling virt_to_page on keyHerbert Xu
When HMAC gets a key longer than the block size of the hash, it needs to feed it as input to the hash to reduce it to a fixed length. As it is HMAC converts the key to a scatter and gather list. However, this doesn't work on certain platforms if the key is not allocated via kmalloc. For example, the keys from tcrypt are stored in the rodata section and this causes it to fail with HMAC on x86-64. This patch fixes this by copying the key to memory obtained via kmalloc before hashing it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2008-04-21[CRYPTO] tcrypt: Change the XTEA test vectorsSebastian Siewior
The third test vector of ECB-XTEA-ENC fails for me all other are fine. I could not find a RFC or something else where they are defined. The test vector has not been modified since git started recording histrory. The implementation is very close (not to say equal) to what is available as Public Domain (they recommend 64 rounds and the in kernel uses 32). Therefore I belive that there is typo somewhere and tcrypt reported always *fail* instead of *okey*. This patch replaces input + result of the third test vector with result + input from the third decryption vector. The key is the same, the other three test vectors are also the reverse.

2008-04-21[CRYPTO] tcrypt: Shrink the tcrypt moduleSebastian Siewior
Currently the tcrypt module is about 2 MiB on x86-32. The main reason for the huge size is the data segment which contains all the test vectors for each algorithm. The test vectors are staticly allocated in an array and the size of the array has been drastically increased by the merge of the Salsa20 test vectors. With a hint from Benedigt Spranger I found a way how I could convert those fixed-length arrays to strings which are flexible in size. VIM and regex were also very helpfull :) So, I am talking about a shrinking of ~97% on x86-32: text data bss dec hex filename 18309 2039708 20 2058037 1f6735 tcrypt-b4.ko 45628 23516 80 69224 10e68 tcrypt.ko Signed-off-by: Sebastian Siewior <sebastian@breakpoint.cc> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2008-04-17dmaengine: ack to flags: make use of the unused bits in the 'ack' fieldDan Williams
'ack' is currently a simple integer that flags whether or not a client is done touching fields in the given descriptor. It is effectively just a single bit of information. Converting this to a flags parameter allows the other bits to be put to use to control completion actions, like dma-unmap, and capture results, like xor-zero-sum == 0. Changes are one of: 1/ convert all open-coded ->ack manipulations to use async_tx_ack and async_tx_test_ack. 2/ set the ack bit at prep time where possible 3/ make drivers store the flags at prep time 4/ add flags to the device_prep_dma_interrupt prototype Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

2008-04-02[CRYPTO] xcbc: Fix crash when ipsec uses xcbc-mac with big data chunkJoy Latten
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.

2008-03-06[CRYPTO] xcbc: Fix crash with IPsecJoy Latten
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.

2008-02-23[CRYPTO] skcipher: Move chainiv/seqiv into crypto_blkcipher moduleHerbert Xu
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 <herbert@gondor.apana.org.au>

Building latest git fails with the following error: ERROR: "crypto_alloc_ablkcipher" [crypto/tcrypt.ko] undefined! This appears to happen because CONFIG_CRYPTO_TEST is set while CONFIG_CRYPTO_BLKCIPHER is not. The following patch fixes the problem for me.

2008-02-06async_tx: replace 'int_en' with operation preparation flagsDan Williams
Pass a full set of flags to drivers' per-operation 'prep' routines. Currently the only flag passed is DMA_PREP_INTERRUPT. The expectation is that arch-specific async_tx_find_channel() implementations can exploit this capability to find the best channel for an operation.
