2018-01-12crypto: tcrypt - free xoutbuf instead of axbufColin Ian King1-1/+1
There seems to be a cut-n-paste bug with the name of the buffer being free'd, xoutbuf should be used instead of axbuf.

2017-12-28crypto: tcrypt - allow setting num of bufsGilad Ben-Yossef1-12/+19
For multiple buffers speed tests, the number of buffers, or requests, used actually sets the level of parallelism a tfm provider may utilize to hide latency. The existing number (of 8) is good for some software based providers but not enough for many HW providers with deep FIFOs. Add a module parameter that allows setting the number of multiple buffers/requests used, leaving the default at 8.

2017-12-28crypto: tcrypt - fix AEAD decryption speed testGilad Ben-Yossef1-1/+29
The AEAD speed test pretended to support decryption, however that support was broken as decryption requires a valid auth field which the test did not provide. Fix this by running the encryption path once with inout/output sgls switched to calculate the auth field prior to performing decryption speed tests.

2017-12-28crypto: tcrypt - use multi buf for ahash mb testGilad Ben-Yossef1-4/+9
The multi buffer ahash speed test was allocating multiple buffers for use with the multiple outstanding requests it was starting but never actually using them (except to free them), instead using a different single statically allocated buffer for all requests. Fix this by actually using the allocated buffers for the test. It is noted that it may seem tempting to instead remove the allocation and free of the multiple buffers and leave things as they are since this is a hash test where the input is read only. However, after consideration I believe that multiple buffers better reflect real life scenario with regard to data cache and TLB behaviours etc. Signed-off-by: Gilad Ben-Yossef <gilad@benyossef.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2017-05-18crypto: tcrypt - don't disable irqs and waitGilad Ben-Yossef1-4/+0
The tcrypt AEAD cycles speed tests disables irqs during the test, which is broken at the very least since commit '1425d2d17f7309c6 ("crypto: tcrypt - Fix AEAD speed tests")' adds a wait for completion as part of the test and probably since switching to the new AEAD API. While the result of taking a cycle count diff may not mean much on SMP systems if the task migrates, it's good enough for tcrypt being the quick & dirty dev tool it is. It's also what all the other (i.e. hash) cycle speed tests do.

This patch resolves a number of issues with the mb speed test function: * The tfm is never freed. * Memory is allocated even when we're not using mb. * When an error occurs we don't wait for completion for other requests. * When an error occurs during allocation we may leak memory. * The test function ignores plen but still runs for plen != blen. * The backlog flag is incorrectly used (may crash).

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>

2015-02-04crypto: tcrypt - fix buflen reminder calculationCristian Stoica1-8/+8
- This fixes the intent of the code to limit the last scatterlist to either a full PAGE or a fraction of it, depending on the number of pages needed by buflen and the available space advertised by XBUFLEN. The original code always sets the last scatterlist to a fraction of a PAGE because the first 'if' is never executed. - Rearrange the second part of the code to remove the conditional from the loop Signed-off-by: Cristian Stoica <cristian.stoica@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
2015-01-13crypto: testmgr - don't use interruptible wait in testsRabin Vincent1-6/+4
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.

2014-12-05crypto: tcrypt - Allow speed testing of arbitrary hash functionsHerbert Xu1-12/+20
This patch allows the testing of arbitrary hash functions specified by the alg module parameter by using them in mode 300 (for sync hash) and mode 400 (for async hash). For example, you could do modprobe tcrypt mode=300 alg='vmac(aes)' Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Print the driver name that is being tested. The driver name can be inferred parsing /proc/crypto but having it in the output is clearer Signed-off-by: Luca Clementi <luca.clementi@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Test vectors were taken from existing test for CBC(DES3_EDE). Associated data has been added to test vectors. HMAC computed with Crypto++ has been used. Following algos have been covered. (a) "authenc(hmac(sha1),cbc(des))" (b) "authenc(hmac(sha1),cbc(des3_ede))" (c) "authenc(hmac(sha224),cbc(des))" (d) "authenc(hmac(sha224),cbc(des3_ede))" (e) "authenc(hmac(sha256),cbc(des))" (f) "authenc(hmac(sha256),cbc(des3_ede))" (g) "authenc(hmac(sha384),cbc(des))" (h) "authenc(hmac(sha384),cbc(des3_ede))" (i) "authenc(hmac(sha512),cbc(des))" (j) "authenc(hmac(sha512),cbc(des3_ede))" Signed-off-by: Vakul Garg <vakul@freescale.com> [NiteshNarayanLal@freescale.com: added hooks for the missing algorithms test and tested the patch] Signed-off-by: Nitesh Lal <NiteshNarayanLal@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
