Date: Tue, 5 Apr 2022 09:27:07 +0200 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Corentin Labbe <clabbe.montjoie@...il.com>, Herbert Xu <herbert@...dor.apana.org.au>, Sasha Levin <sashal@...nel.org> Subject: [PATCH 5.10 133/599] crypto: authenc - Fix sleep in atomic context in decrypt_tail From: Herbert Xu <herbert@...dor.apana.org.au> [ 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.
