This is a note to let you know that I have just added a patch titled sctp: Use software crc32 checksum when xfrm transform will to the linux-3.5.y-queue branch of the 3.5.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-3.5.y-queue If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.5.y.z tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Luis ------ From 31d3a803ef0ca5d5a5d0da84116c3b051c5e5d71 Mon Sep 17 00:00:00 2001 From: Fan Du <fan.du@windriver.com> Date: Tue, 15 Oct 2013 22:01:30 -0400 Subject: [PATCH] sctp: Use software crc32 checksum when xfrm transform will happen. commit 27127a82561a2a3ed955ce207048e1b066a80a2a upstream. igb/ixgbe have hardware sctp checksum support, when this feature is enabled and also IPsec is armed to protect sctp traffic, ugly things happened as xfrm_output checks CHECKSUM_PARTIAL to do checksum operation(sum every thing up and pack the 16bits result in the checksum field). The result is fail establishment of sctp communication.
