Subject: [PATCH net 1/2] Revert "Revert "sctp: Fix bundling of SHUTDOWN with COOKIE-ACK""
Date: Mon,  3 May 2021 04:36:58 +0800	[thread overview]
Message-ID: <8b4e11506ccf62e18944bc94a02ea86c4c4de26e.1619987699.git.lucien.xin@gmail.com> (raw)
In-Reply-To: <cover.1619987699.git.lucien.xin@gmail.com>
In-Reply-To: <cover.1619987699.git.lucien.xin@gmail.com>

This reverts commit 7e9269a5acec6d841d22e12770a0b02db4f5d8f2.

As Jere notice, commit 35b4f24415c8 ("sctp: do asoc update earlier
in sctp_sf_do_dupcook_a") only keeps the SHUTDOWN and COOKIE-ACK
with the same asoc, not transport. So we have to bring this patch
back.
