Subject: [PATCH] crypto: aead - fix for multiple operations on AF_ALG sockets
Date: Tue, 25 Aug 2015 11:59:15 +0200 [thread overview]
Message-ID: <1440496755-15105-1-git-send-email-larper@axis.com> (raw)
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.
