This is a note to let you know that I have just added a patch titled crypto: caam - fix addressing of struct member to the linux-3.13.y-queue branch of the 3.13.y.z extended stable tree which can be found at: http://kernel.ubuntu.com/git?p=ubuntu/linux.git;a=shortlog;h=refs/heads/linux-3.13.y-queue This patch is scheduled to be released in version 3.13.11.10. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.13.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 0567df624dcd5baa8f969672999a04d36a8d560a Mon Sep 17 00:00:00 2001 From: Cristian Stoica <cristian.stoica@freescale.com> Date: Thu, 14 Aug 2014 13:51:57 +0300 Subject: crypto: caam - fix addressing of struct member commit 4451d494b1910bf7b7f8381a637d0fe6d2142467 upstream. buf_0 and buf_1 in caam_hash_state are not next to each other. Accessing buf_1 is incorrect from &buf_0 with an offset of only size_of(buf_0). The same issue is also with buflen_0 and buflen_1 Signed-off-by: Cristian Stoica <cristian.stoica@freescale.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Kamal Mostafa <kamal@canonical.com> --- drivers/crypto/caam/caamhash.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) -- 1.9.1
