kernel/crypto/sm3_generic.c, branch linux-5.1.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-5.1.y2019-01-10T13:37:32Zcrypto: sm3 - fix undefined shift by >= width of value2019-01-10T13:37:32ZEric Biggersebiggers@google.com2019-01-09T06:12:41Zurn:sha1:d45a90cb5d061fa7d411b974b950fe0b8bc5f265
sm3_compress() calls rol32() with shift >= 32, which causes undefined
behavior. This is easily detected by enabling CONFIG_UBSAN.
Explicitly AND with 31 to make the behavior well defined.

crypto: shash - remove useless setting of type flags2018-07-08T16:30:24ZEric Biggersebiggers@google.com2018-06-30T22:16:11Zurn:sha1:e50944e219f908968a6e01fbd0e8811a33bd5f04
Many shash algorithms set .cra_flags = CRYPTO_ALG_TYPE_SHASH. But this
is redundant with the C structure type ('struct shash_alg'), and
crypto_register_shash() already sets the type flag automatically,
clearing any type flag that was already there. Apparently the useless
assignment has just been copy+pasted around.
So, remove the useless assignment from all the shash algorithms.
This patch shouldn't change any actual behavior.
