This regression is probably introduced with patch: crypto: xts - Convert to skcipher by Herbert Xu <herb...@gondor.apana.org.au> https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/crypto/xts.c?h=v4.12-rc2&id=f1c131b45410a202eb45cc55980a7a9e4e4b4f40 [ 18.912744] random: crng init done [ 26.085491] ------------[ cut here ]------------ [ 26.087764] WARNING: CPU: 0 PID: 176 at crypto/skcipher.c:431 skcipher_walk_first+0x5c/0x14c [ 26.090045] Modules linked in: [ 26.092284] CPU: 0 PID: 176 Comm: cryptomgr_test Not tainted 4.12.0-rc2 #2 [ 26.094546] Hardware name: Rockchip (Device Tree) [ 26.096799] [<8022f9d4>] (unwind_backtrace) from [<8022aeec>] (show_stack+0x20/0x24) [ 26.099069] [<8022aeec>] (show_stack) from [<8060fc14>] (dump_stack+0x88/0xa4) [ 26.101339] [<8060fc14>] (dump_stack) from [<80244f2c>] (__warn+0xf0/0x110) [ 26.103598] [<80244f2c>] (__warn) from [<80244ff0>] (warn_slowpath_null+0x30/0x38) [ 26.105819] [<80244ff0>] (warn_slowpath_null) from [<805c3264>] (skcipher_walk_first+0x5c/0x14c) [ 26.108054] [<805c3264>] (skcipher_walk_first) from [<805c341c>] (skcipher_walk_skcipher+0xc8/0xcc) [ 26.110310] [<805c341c>] (skcipher_walk_skcipher) from [<805c365c>] (skcipher_walk_virt+0x2c/0x48) [ 26.112593] [<805c365c>] (skcipher_walk_virt) from [<805cece4>] (post_crypt+0x44/0x1cc) [ 26.114898] [<805cece4>] (post_crypt) from [<805cf33c>] (encrypt_done+0x5c/0x7c) [ 26.117204] [<805cf33c>] (encrypt_done) from [<80874d40>] (rk_crypto_complete+0x28/0x2c) [ 26.119544] [<80874d40>] (rk_crypto_complete) from [<80875044>] (rk_ablk_rx+0x80/0x128) [ 26.121899] [<80875044>] (rk_ablk_rx) from [<80874358>] (rk_crypto_irq_handle+0x68/0x94) [ 26.124294] [<80874358>] (rk_crypto_irq_handle) from [<8029838c>] (__handle_irq_event_percpu+0x54/0x218) [ 26.126714] [<8029838c>] (__handle_irq_event_percpu) from [<80298588>] (handle_irq_event_percpu+0x38/0x8c) [ 26.129152] [<80298588>] (handle_irq_event_percpu) from [<80298630>] (handle_irq_event+0x54/0x78) [ 26.131601] [<80298630>] (handle_irq_event) from [<8029c3a0>] (handle_fasteoi_irq+0xbc/0x140) [ 26.134096] [<8029c3a0>] (handle_fasteoi_irq) from [<80297afc>] (generic_handle_irq+0x28/0x38) [ 26.136575] [<80297afc>] (generic_handle_irq) from [<80297bbc>] (__handle_domain_irq+0xb0/0xc4) [ 26.139029] [<80297bbc>] (__handle_domain_irq) from [<80201584>] (gic_handle_irq+0x58/0x84) [ 26.141497] [<80201584>] (gic_handle_irq) from [<80a73e78>] (__irq_svc+0x58/0x74) [ 26.143955] Exception stack(0x821bdaa0 to 0x821bdae8) [ 26.146386] daa0: ed13ab80 00000000 6cafb000 000044fb ed13ab80 82106400 810c12c0 8204de40 [ 26.148869] dac0: edbbc2c0 6cafb000 80a6d804 821bdb34 821bdb38 821bdaf0 80a6d804 8026c3e8 [ 26.151359] dae0: 60080013 ffffffff [ 26.153842] [<80a73e78>] (__irq_svc) from [<8026c3e8>] (finish_task_switch+0xf4/0x2b4) ^[[?1;2c[ 26.156355] [<8026c3e8>] (finish_task_switch) from [<80a6d804>] (__schedule+0x5f4/0x974) [ 26.158899] [<80a6d804>] (__schedule) from [<80a6dc64>] (preempt_schedule_common+0x20/0x30) [ 26.161452] [<80a6dc64>] (preempt_schedule_common) from [<80a6dcb4>] (_cond_resched+0x40/0x48) [ 26.164031] [<80a6dcb4>] (_cond_resched) from [<80a6e8bc>] (wait_for_common+0x38/0x1a8) [ 26.166656] [<80a6e8bc>] (wait_for_common) from [<80a6ea4c>] (wait_for_completion+0x20/0x24) [ 26.169243] [<80a6ea4c>] (wait_for_completion) from [<805c6fa0>] (__test_skcipher+0x314/0x8a8) [ 26.171784] [<805c6fa0>] (__test_skcipher) from [<805c99a0>] (test_skcipher+0x38/0xc4) [ 26.174299] [<805c99a0>] (test_skcipher) from [<805c9ac0>] (alg_test_skcipher+0x94/0xb0) ^[[?1;2c^[[?1;2c[ 26.176809] [<805c9ac0>] (alg_test_skcipher) from [<805ca740>] (alg_test+0x240/0x2e0)^[[?1;2c [ 26.179325] [<805ca740>] (alg_test) from [<805c6458>] (cryptomgr_test+0x34/0x54) [ 26.181841] [<805c6458>] (cryptomgr_test) from [<802641c8>] (kthread+0x154/0x16c) [ 26.184359] [<802641c8>] (kthread) from [<80226e08>] (ret_from_fork+0x14/0x2c) [ 26.186866] ---[ end trace 3311d538cc9cc0a4 ]--- [ 26.189429] alg: skcipher: encryption failed on test 1 for xts(ecb-aes-rk): ret=35 [ 26.192050] device-mapper: table: 253:0: crypt: Error allocating crypto tfm [ 26.194682] device-mapper: ioctl: error adding target to table Best Regards -Emil
