2016-02-06crypto: tcrypt - Use ahashHerbert Xu
This patch removes the last user of the obsolete crypto_hash interface, tcrypt, by simply switching it over to ahash. In fact it already has all the code there so it's just a matter of calling the ahash speed test code with the right mask. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-11-23crypto: tcrypt - fix keysize argument of test_aead_speed for gcm(aes)Cyrille Pitchen
The key sizes used by AES in GCM mode should be 128, 192 or 256 bits (16, 24 or 32 bytes). There is no additional 4byte nonce as for RFC 4106. Signed-off-by: Cyrille Pitchen <cyrille.pitchen@atmel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-09-21crypto: tcrypt - avoid mapping from module image addressesHoria Geant?
The output buffer in test_ahash_speed will point to an address located within the tcrypt module image. This causes problems when trying to DMA map the buffer. For e.g. on ARM-based LS1021A, a page fault occurs within the DMA API when trying to access the struct page returned by virt_to_page(output): insmod tcrypt.ko mode=403 testing speed of async sha1 (sha1-caam) test 0 ( 16 byte blocks, 16 bytes per update, 1 updates): Unable to handle kernel paging request at virtual address f07e9080 pgd = e58d0e00 [f07e9080] *pgd=80000080007003, *pmd=00000000 Internal error: Oops: 206 [#1] SMP THUMB2 Modules linked in: tcrypt(+) CPU: 1 PID: 1119 Comm: insmod Not tainted 4.2.0-rc1-256134-gbf433416e675 #1 Hardware name: Freescale LS1021A task: ea063900 ti: e5a34000 task.ti: e5a34000 PC is at dma_cache_maint_page+0x38/0xd0 LR is at __dma_page_cpu_to_dev+0x15/0x64 pc : [<800155a0>] lr : [<8001564d>] psr: 000f0033 sp : e5a35ca0 ip : 8063df00 fp : f07e9080 r10: 00000cd0 r9 : 8063df00 r8 : 805a2f04 r7 : 0017f804 r6 : 00000002 r5 : ee7f9000 r4 : 00000014 r3 : 80612d40 r2 : 01ff0080 r1 : 00000380 r0 : ee7f9000 Flags: nzcv IRQs on FIQs on Mode SVC_32 ISA Thumb Segment user Control: 70c5387d Table: e58d0e00 DAC: 9b7ede70 Process insmod (pid: 1119, stack limit = 0xe5a34210) Stack: (0xe5a35ca0 to 0xe5a36000) [...] [<800155a0>] (dma_cache_maint_page) from [<8001564d>] (__dma_page_cpu_to_dev+0x15/0x64) [<8001564d>] (__dma_page_cpu_to_dev) from [<800156eb>] (arm_dma_map_page+0x1f/0x44) [<800156eb>] (arm_dma_map_page) from [<802935e3>] (ahash_digest+0x35f/0x510) [<802935e3>] (ahash_digest) from [<7f800d03>] (test_ahash_speed.constprop.6+0x24a/0x4e4 [tcrypt]) [<7f800d03>] (test_ahash_speed.constprop.6 [tcrypt]) from [<7f802fd5>] (do_test+0x1898/0x2058 [tcrypt]) [<7f802fd5>] (do_test [tcrypt]) from [<7f80802f>] (tcrypt_mod_init+0x2e/0x63 [tcrypt]) [<7f80802f>] (tcrypt_mod_init [tcrypt]) from [<80009517>] (do_one_initcall+0xb3/0x134) [<80009517>] (do_one_initcall) from [<80351ec7>] (do_init_module+0x3b/0x13c) [<80351ec7>] (do_init_module) from [<8005cc3f>] (load_module+0x97b/0x9dc) [<8005cc3f>] (load_module) from [<8005cd8d>] (SyS_finit_module+0x35/0x3e) [<8005cd8d>] (SyS_finit_module) from [<8000d101>] (ret_fast_syscall+0x1/0x4c) Code: 1aba 0152 eb00 0b02 (5882) 0f92 addr2line -f -i -e vmlinux 800155a0 page_zonenum include/linux/mm.h:728 page_zone include/linux/mm.h:881 dma_cache_maint_page arch/arm/mm/dma-mapping.c:822 Signed-off-by: Horia Geant? <horia.geanta@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-03-11crypto: tcrypt - fix uninit sg entries in test_acipher_speedHoria Geant?
Commit 5be4d4c94b1f ("crypto: replace scatterwalk_sg_next with sg_next") did not consider the fact that scatterwalk_sg_next() was looking at sg entry length, while sg_next() looks at the "chained" sg bit. This should have no effect in theory. However in practice, there are cases where the sg table is initialized to a number of entries and some of them are not properly configured. While scatterwalk_sg_next() would have returned NULL (since sg length = 0 and sg page_link = 0), sg_next() happily returns the next unconfigured sg entry. insmod tcrypt.ko mode=500 sec=1 testing speed of async cbc(aes) (cbc-aes-talitos) encryption test 0 (128 bit key, 16 byte blocks): Unable to handle kernel paging request for data at address 0x00000000 Faulting instruction address: 0xc00d79e4 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=8 P1022 DS Modules linked in: tcrypt(+) talitos CPU: 0 PID: 2670 Comm: insmod Not tainted 4.0.0-rc1-QorIQ-SDK-V1.6+g904f1ca82209 #1 task: e8de3200 ti: e70bc000 task.ti: e70bc000 NIP: c00d79e4 LR: f92d223c CTR: c00d79c8 REGS: e70bda00 TRAP: 0300 Not tainted (4.0.0-rc1-QorIQ-SDK-V1.6+g904f1ca82209) MSR: 00029000 <CE,EE,ME> CR: 84428f22 XER: 00000000 DEAR: 00000000 ESR: 00000000 GPR00: f92d223c e70bdab0 e8de3200 00000000 e70bdbb8 00000001 00000000 00000000 GPR08: 00000000 00000000 c08b0380 27282010 c00d79c8 1003a634 00000000 e70bdf1c GPR16: e70bdef0 00000020 00000000 c08c0000 00000010 00000000 e70bdbb8 00000010 GPR24: e976d3a8 00000010 00000000 e70bdbd8 e8961010 00000001 c086e560 00000000 NIP [c00d79e4] page_address+0x1c/0x110 LR [f92d223c] talitos_map_sg+0x130/0x184 [talitos] Call Trace: [e70bdab0] [00000010] 0x10 (unreliable) [e70bdad0] [f92d223c] talitos_map_sg+0x130/0x184 [talitos] [e70bdb00] [f92d30d8] common_nonsnoop.constprop.13+0xc0/0x304 [talitos] [e70bdb30] [f933fd90] test_acipher_speed+0x434/0x7dc [tcrypt] [e70bdcc0] [f934318c] do_test+0x2478/0x306c [tcrypt] [e70bdd80] [f11fe058] tcrypt_mod_init+0x58/0x100 [tcrypt] [e70bdda0] [c0002354] do_one_initcall+0x90/0x1f4 [e70bde10] [c061fe00] do_init_module+0x60/0x1ac [e70bde30] [c00a79f0] load_module+0x185c/0x1f88 [e70bdee0] [c00a82b0] SyS_finit_module+0x7c/0x98 [e70bdf40] [c000e8b0] ret_from_syscall+0x0/0x3c Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2015-01-13crypto: testmgr - don't use interruptible wait in testsRabin Vincent
tcrypt/testmgr uses wait_for_completion_interruptible() everywhere when it waits for a request to be completed. If it's interrupted, then the test is aborted and the request is freed. However, if any of these calls actually do get interrupted, the result will likely be a kernel crash, when the driver handles the now-freed request. Use wait_for_completion() instead.

2013-01-08crypto: ctr - make rfc3686 asynchronous block cipherJussi Kivilinna
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.

2012-09-27crypto, tcrypt: remove local_bh_disable/enable() around ↵Suresh Siddha
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>

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>
