* crypto: algif_rng - zeroize buffer with random dataStephan Mueller2015-03-161-1/+1
| | | | | | | | | Due to the change to RNGs to always return zero in success case, the RNG interface must zeroize the buffer with the length provided by the caller. Signed-off-by: Stephan Mueller <smueller@chronox.de> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | Instead of using static hwrng structure that is reused between binds/unbinds of the device let's embed it into driver's private structure that we allocate. This way we are guaranteed not to stumble onto something left from previous bind attempt.

* hwrng: bcm63xx - make use of devm_hwrng_registerDmitry Torokhov2015-03-161-56/+31
| | | | | | | | | | | | | This change converts bcm63xx-rng to use devm* API for managing all resources, which allows us to dispense with the rest of error handling path and remove() function. Also we combine hwern and driver-private data into a single allocation, use clk_prepare_enable() instead of "naked" clk_enable() and move clock enabling/disabling into hwrnd inti(0 and cleanup() methods so the clock stays off until rng is used.

* hwrng: omap - remove #ifdefery around PM methodsDmitry Torokhov2015-03-121-12/+3
| | | | | | | | | | | | | | Instead of using #ifdefs let's mark suspend and resume methods as __maybe_unused which will suppress compiler warnings about them being unused and provide better compile coverage. Because SIMPLE_DEV_PM_OPS() produces an empty omap_rng_pm structure in case of !CONFIG_PM_SLEEP neither omap_rng_suspend nor omap_rng_resume will end up being referenced and the change will not result in increasing image size.

* crypto: tcrypt - fix uninit sg entries in test_acipher_speedHoria Geant?2015-03-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix rng_unmap_ctx's DMA_UNMAP size problem for caam_rng, else system would report the below calltrace during cleanup caam_rng. Since rng_create_sh_desc() creates a fixed descriptor of exactly 4 command-lengths now, also update DESC_RNG_LEN to (4 * CAAM_CMD_SZ). caam_jr ffe301000.jr: DMA-API: device driver frees DMA memory with different size [device address=0x000000007f080010] [map size=16 bytes] [unmap size=40 bytes] ------------[ cut here ]------------ WARNING: at lib/dma-debug.c:887 Modules linked in: task: c0000000f7cdaa80 ti: c0000000e5340000 task.ti: c0000000e5340000 NIP: c0000000004f5bc8 LR: c0000000004f5bc4 CTR: c0000000005f69b0 REGS: c0000000e53433c0 TRAP: 0700 Not tainted MSR: 0000000080029000 <CE,EE,ME> CR: 24088482 XER: 00000000 SOFTE: 0 GPR00: c0000000004f5bc4 c0000000e5343640 c0000000012af360 000000000000009f GPR04: 0000000000000000 00000000000000a0 c000000000d02070 c000000015980660 GPR08: c000000000cff360 0000000000000000 0000000000000000 c0000000012da018 GPR12: 00000000000001e3 c000000001fff780 00000000100f0000 0000000000000001 GPR16: 0000000000000002 0000000000000000 0000000000000000 0000000000000000 GPR20: 0000000000000000 0000000000000000 ffffffffffffffff 0000000000000001 GPR24: 0000000000000001 0000000000000001 0000000000000000 0000000000000001 GPR28: c000000001556b90 c000000001565b80 c0000000e5343750 c0000000f9427480 NIP [c0000000004f5bc8] .check_unmap+0x538/0x9c0 LR [c0000000004f5bc4] .check_unmap+0x534/0x9c0 Call Trace: [c0000000e5343640] [c0000000004f5bc4] .check_unmap+0x534/0x9c0 (unreliable) [c0000000e53436e0] [c0000000004f60d4] .debug_dma_unmap_page+0x84/0xb0 [c0000000e5343810] [c00000000082f9d4] .caam_cleanup+0x1d4/0x240 [c0000000e53438a0] [c00000000056cc88] .hwrng_unregister+0xd8/0x1c0 Instruction dump: 7c641b78 41de0410 e8a90050 2fa50000 419e0484 e8de0028 e8ff0030 3c62ff90 e91e0030 38638388 48546ed9 60000000 <0fe00000> 3c62ff8f 38637fc8 48546ec5 ---[ end trace e43fd1734d6600df ]--- Signed-off-by: Yanjiang Jin <yanjiang.jin@windriver.com> Acked-by: Kim Phillips <kim.phillips@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

* crypto: drbg - remove superflowous memsetsStephan Mueller2015-03-041-18/+0
| | | | | | | | | | | The DRBG code contains memset(0) calls to initialize a varaible that are not necessary as the variable is always overwritten by the processing.

* crypto: drbg - use single block cipher APIStephan Mueller2015-03-041-23/+16
| | | | | | | | | | | | | The CTR DRBG only encrypts one single block at a time. Thus, use the single block crypto API to avoid additional overhead from the block chaining modes. With the patch, the speed of the DRBG increases between 30% and 40%. The DRBG still passes the CTR DRBG CAVS test.
