2012-06-12crypto: twofish - add x86_64/avx assembler implementationJohannes Goetzfried
This patch adds a x86_64/avx assembler implementation of the Twofish block cipher. The implementation processes eight blocks in parallel (two 4 block chunk AVX operations). The table-lookups are done in general-purpose registers. For small blocksizes the 3way-parallel functions from the twofish-x86_64-3way module are called. A good performance increase is provided for blocksizes greater or equal to 128B. Patch has been tested with tcrypt and automated filesystem tests. Tcrypt benchmark results: Intel Core i5-2500 CPU (fam:6, model:42, step:7) twofish-avx-x86_64 vs. twofish-x86_64-3way 128bit key: (lrw:256bit) (xts:256bit) size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec lrw-enc lrw-dec xts-enc xts-dec 16B 0.96x 0.97x 1.00x 0.95x 0.97x 0.97x 0.96x 0.95x 0.95x 0.98x 64B 0.99x 0.99x 1.00x 0.99x 0.98x 0.98x 0.99x 0.98x 0.99x 0.98x 256B 1.20x 1.21x 1.00x 1.19x 1.15x 1.14x 1.19x 1.20x 1.18x 1.19x 1024B 1.29x 1.30x 1.00x 1.28x 1.23x 1.24x 1.26x 1.28x 1.26x 1.27x 8192B 1.31x 1.32x 1.00x 1.31x 1.25x 1.25x 1.28x 1.29x 1.28x 1.30x 256bit key: (lrw:384bit) (xts:512bit) size ecb-enc ecb-dec cbc-enc cbc-dec ctr-enc ctr-dec lrw-enc lrw-dec xts-enc xts-dec 16B 0.96x 0.96x 1.00x 0.96x 0.97x 0.98x 0.95x 0.95x 0.95x 0.96x 64B 1.00x 0.99x 1.00x 0.98x 0.98x 1.01x 0.98x 0.98x 0.98x 0.98x 256B 1.20x 1.21x 1.00x 1.21x 1.15x 1.15x 1.19x 1.20x 1.18x 1.19x 1024B 1.29x 1.30x 1.00x 1.28x 1.23x 1.23x 1.26x 1.27x 1.26x 1.27x 8192B 1.31x 1.33x 1.00x 1.31x 1.26x 1.26x 1.29x 1.29x 1.28x 1.30x twofish-avx-x86_64 vs aes-asm (8kB block): 128bit 256bit ecb-enc 1.19x 1.63x ecb-dec 1.18x 1.62x cbc-enc 0.75x 1.03x cbc-dec 1.23x 1.67x ctr-enc 1.24x 1.65x ctr-dec 1.24x 1.65x lrw-enc 1.15x 1.53x lrw-dec 1.14x 1.52x xts-enc 1.16x 1.56x xts-dec 1.16x 1.56x Signed-off-by: Johannes Goetzfried <Johannes.Goetzfried@informatik.stud.uni-erlangen.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
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.

2009-06-02crypto: tcrypt - Do not exit on success in fips modeJarod Wilson
At present, the tcrypt module always exits with an -EAGAIN upon successfully completing all the tests its been asked to run. In fips mode, integrity checking is done by running all self-tests from the initrd, and its much simpler to check the ret from modprobe for success than to scrape dmesg and/or /proc/crypto. Simply stay loaded, giving modprobe a retval of 0, if self-tests all pass and we're in fips mode. A side-effect of tracking success/failure for fips mode is that in non-fips mode, self-test failures will return the actual failure return codes, rather than always returning -EAGAIN, which seems more correct anyway. The tcrypt_test() portion of the patch is dependent on my earlier pair of patches that skip non-fips algs in fips mode, at least to achieve the fully intended behavior. Nb: testing this patch against the cryptodev tree revealed a test failure for sha384, which I have yet to look into...

If tcrypt is to be used as a run-time integrity test, it needs to be more resilient in a hostile environment. For a start allocating 32K of physically contiguous memory is definitely out. This patch teaches it to use separate pages instead. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-08-13crypto: tcrypt - Fix AEAD chunk testingHerbert Xu
My changeset 4b22f0ddb6564210c9ded7ba25b2a1007733e784 crypto: tcrpyt - Remove unnecessary kmap/kunmap calls introduced a typo that broke AEAD chunk testing. In particular, axbuf should really be xbuf. There is also an issue with testing the last segment when encrypting. The additional part produced by AEAD wasn't tested. Similarly, on decryption the additional part of the AEAD input is mistaken for corruption. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-07-10crypto: hash - Move ahash functions into crypto/hash.hHerbert Xu
All new crypto interfaces should go into individual files as much as possible in order to ensure that crypto.h does not collapse under its own weight. This patch moves the ahash code into crypto/hash.h and crypto/internal/hash.h respectively. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-07-10crypto: tcrpyt - Remove unnecessary kmap/kunmap callsHerbert Xu
Noticed by Neil Horman: we are doing unnecessary kmap/kunmap calls on kmalloced memory. This patch removes them. For the purposes of testing SG construction, the underlying crypto code already does plenty of kmap/kunmap calls anyway. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2008-07-10[CRYPTO] tcrypt: Add self test for des3_ebe cipher operating in cbc modeNeil Horman
Patch to add checking of DES3 test vectors using CBC mode. FIPS-140-2 compliance mandates that any supported mode of operation must include a self test. This satisfies that requirement for cbc(des3_ede). The included test vector was generated by me using openssl. Key/IV was generated with the following command: openssl enc -des_ede_cbc -P input and output values were generated by repeating the string "Too many secrets" a few times over, truncating it to 128 bytes, and encrypting it with openssl using the aformentioned key.

2008-07-10[CRYPTO] tcrypt: Catch cipher destination memory corruptionPatrick McHardy
Check whether the destination buffer is written to beyond the last byte contained in the scatterlist. Also change IDX1 of the cross-page access offsets to a multiple of 4. This triggers a corruption in the HIFN driver and doesn't seem to negatively impact other testcases.

2008-07-10[CRYPTO] tcrpyt: Get rid of change log in sourceHerbert Xu
Change logs should be kept in source control systems, not the source. This patch removes the change log from tcrpyt to stop people from extending it any more. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2008-07-08crypto: tcrypt - Fix memory leak in test_cipherDarren Jenkins
Coverity CID: 2306 & 2307 RESOURCE_LEAK In the second for loop in test_cipher(), data is allocated space with kzalloc() and is only ever freed in an error case. Looking at this loop, data is written to this memory but nothing seems to read from it. So here is a patch removing the allocation, I think this is the right fix. Only compile tested.

2008-04-21[CRYPTO] tcrypt: Change the usage of the test vectorsSebastian Siewior
The test routines (test_{cipher,hash,aead}) are makeing a copy of the test template and are processing the encryption process in place. This patch changes the creation of the copy so it will work even if the source address of the input data isn't an array inside of the template but a pointer.
