This is a note to let you know that I have just added a patch titled sctp: translate host order to network order when setting a hmacid to the linux-3.19.y-queue branch of the 3.19.y-ckt extended stable tree which can be found at: http://kernel.ubuntu.com/git/ubuntu/linux.git/log/?h=linux-3.19.y-queue This patch is scheduled to be released in version 3.19.8-ckt12. If you, or anyone else, feels it should not be added to this tree, please reply to this email. For more information about the 3.19.y-ckt tree, see https://wiki.ubuntu.com/Kernel/Dev/ExtendedStable Thanks. -Kamal ------ From 42461222036bce1b3cbd94e071dd7b35e890617f Mon Sep 17 00:00:00 2001 From: lucien <lucien.xin@gmail.com> Date: Thu, 12 Nov 2015 13:07:07 +0800 Subject: sctp: translate host order to network order when setting a hmacid commit ed5a377d87dc4c87fb3e1f7f698cba38cd893103 upstream. now sctp auth cannot work well when setting a hmacid manually, which is caused by that we didn't use the network order for hmacid, so fix it by adding the transformation in sctp_auth_ep_set_hmacs. even we set hmacid with the network order in userspace, it still can't work, because of this condition in sctp_auth_ep_set_hmacs(): if (id > SCTP_AUTH_HMAC_ID_MAX) return -EOPNOTSUPP; so this wasn't working before and thus it won't break compatibility.
