From af3c34eb94104035c5f65d046126aa79199acece Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Wed, 19 Jan 2022 17:58:40 +1100 Subject: crypto: authenc - Fix sleep in atomic context in decrypt_tail [ Upstream commit 66eae850333d639fc278d6f915c6fc01499ea893 ] The function crypto_authenc_decrypt_tail discards its flags argument and always relies on the flags from the original request when starting its sub-request. This is clearly wrong as it may cause the SLEEPABLE flag to be set when it shouldn't.
