This is a note to let you know that I have just added a patch titled cifs: adjust sequence number downward after signing 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. -Herton ------ From fb5a6538f808693823b655202a48ea09af4bed3d Mon Sep 17 00:00:00 2001 From: Jeff Layton <jlayton@redhat.com> Date: Thu, 27 Dec 2012 08:05:03 -0500 Subject: [PATCH] cifs: adjust sequence number downward after signing NT_CANCEL request commit 31efee60f489c759c341454d755a9fd13de8c03d upstream. When a call goes out, the signing code adjusts the sequence number upward by two to account for the request and the response. An NT_CANCEL however doesn't get a response of its own, it just hurries the server along to get it to respond to the original request more quickly. Therefore, we must adjust the sequence number back down by one after signing a NT_CANCEL request.
