Jia He 6e88f01206 crypto: arm64/aes-blk - fix and move skcipher_walk_done out of kernel_neon_begin, _end ... In a arm64 server(QDF2400),I met a similar might-sleep warning as [1]: [ 7.019116] BUG: sleeping function called from invalid context at ./include/crypto/algapi.h:416 [ 7.027863] in_atomic(): 1, irqs_disabled(): 0, pid: 410, name: cryptomgr_test [ 7.035106] 1 lock held by cryptomgr_test/410: [ 7.039549] #0: (ptrval) (&drbg->drbg_mutex){+.+.}, at: drbg_instantiate+0x34/0x398 [ 7.048038] CPU: 9 PID: 410 Comm: cryptomgr_test Not tainted 4.17.0-rc6+ #27 [ 7.068228] dump_backtrace+0x0/0x1c0 [ 7.071890] show_stack+0x24/0x30 [ 7.075208] dump_stack+0xb0/0xec [ 7.078523] ___might_sleep+0x160/0x238 [ 7.082360] skcipher_walk_done+0x118/0x2c8 [ 7.086545] ctr_encrypt+0x98/0x130 [ 7.090035] simd_skcipher_encrypt+0x68/0xc0 [ 7.094304] drbg_kcapi_sym_ctr+0xd4/0x1f8 [ 7.098400] drbg_ctr_update+0x98/0x330 [ 7.102236] drbg_seed+0x1b8/0x2f0 [ 7.105637] drbg_instantiate+0x2ac/0x398 [ 7.109646] drbg_kcapi_seed+0xbc/0x188 [ 7.113482] crypto_rng_reset+0x4c/0xb0 [ 7.117319] alg_test_drbg+0xec/0x330 [ 7.120981] alg_test.part.6+0x1c8/0x3c8 [ 7.124903] alg_test+0x58/0xa0 [ 7.128044] cryptomgr_test+0x50/0x58 [ 7.131708] kthread+0x134/0x138 [ 7.134936] ret_from_fork+0x10/0x1c Seems there is a bug in Ard Biesheuvel's commit.
