Message-Id: <1440496755-15105-1-git-send-email-larper@axis.com> Date: Tue, 25 Aug 2015 11:59:15 +0200 From: Lars Persson <lars.persson@...s.com> To: herbert@...dor.apana.org.au, davem@...emloft.net, linux-crypto@...r.kernel.org, linux-kernel@...r.kernel.org Cc: Lars Persson <larper@...s.com> Subject: [PATCH] crypto: aead - fix for multiple operations on AF_ALG sockets The tsgl scatterlist must be re-initialized after each operation. Otherwise the sticky bits in the page_link will corrupt the list with pre-mature termination or false chaining.
