crypto: tcrypt - fix keysize argument of test_aead_speed for gcm(aes)

2015-11-23T12:55:52Z

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 Signed-off-by: Herbert Xu

crypto: tcrypt - avoid mapping from module image addresses

2015-09-21T14:00:36Z

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?
