| | | | | | | | | | | | | | | | | | transform framework" This reverts commits 67822649d7305caf3dd50ed46c27b99c94eff996 39761214eefc6b070f29402aa1165f24d789b3f7 0b95a7f85718adcbba36407ef88bba0a7379ed03 31d939625a9a20b1badd2d4e6bf6fd39fa523405 2d31e518a42828df7877bca23a958627d60408bc Unfortunately this change broke boot on some systems that used an initrd which does not include the newly created crct10dif modules. As these modules are required by sd_mod under certain configurations this is a serious problem. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
* crypto: crct10dif - Simple correctness and speed test for CRCT10DIF hashTim Chen2013-05-241-0/+8
| | | | | | | | | | | | | | | These are simple tests to do sanity check of CRC T10 DIF hash. The correctness of the transform can be checked with the command modprobe tcrypt mode=47 The speed of the transform can be evaluated with the command modprobe tcrypt mode=320 Set the cpu frequency to constant and turn turbo off when running the speed test so the frequency governor will not tweak the frequency and affects the measurements.

* crypto: ctr - make rfc3686 asynchronous block cipherJussi Kivilinna2013-01-081-0/+4
| | | | | | | | | | | | | | Some hardware crypto drivers register asynchronous ctr(aes), which is left unused in IPSEC because rfc3686 template only supports synchronous block ciphers. Some other drivers register rfc3686(ctr(aes)) to workaround this limitation but not all. This patch changes rfc3686 to use asynchronous block ciphers, to allow async ctr(aes) algorithms to be utilized automatically by IPSEC.

* crypto, tcrypt: remove local_bh_disable/enable() around ↵Suresh Siddha2012-09-271-6/+0
| | | | | | | | | | | | | | | | | | | | | | | local_irq_disable/enable() Ran into this while looking at some new crypto code using FPU hitting a WARN_ON_ONCE(!irq_fpu_usable()) in the kernel_fpu_begin() on a x86 kernel that uses the new eagerfpu model. In short, current eagerfpu changes return 0 for interrupted_kernel_fpu_idle() and the in_interrupt() thinks it is in the interrupt context because of the local_bh_disable(). Thus resulting in the WARN_ON(). Remove the local_bh_disable/enable() calls around the existing local_irq_disable/enable() calls. local_irq_disable/enable() already disables the BH. [ If there are any other legitimate users calling kernel_fpu_begin() from the process context but with BH disabled, then we can look into fixing the irq_fpu_usable() in future. ] Signed-off-by: Suresh Siddha <suresh.b.siddha@intel.com> Cc: Tim Chen <tim.c.chen@linux.intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: twofish - add x86_64/avx assembler implementationJohannes Goetzfried2012-06-121-0/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* crypto: tcrypt - Do not exit on success in fips modeJarod Wilson2009-06-021-74/+90
| | | | | | | | | | | | | | | | | | | | | | | | | | 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...
