Subject: [PATCH 3.14 31/37] tcp: fixing TLPs FIN recovery
Date: Mon, 13 Oct 2014 04:24:28 +0200 [thread overview]
Message-ID: <20141013022401.584919904@linuxfoundation.org> (raw)
In-Reply-To: <20141013022400.286360067@linuxfoundation.org>
3.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Per Hurtig <per.hurtig@kau.se>
[ Upstream commit bef1909ee3ed1ca39231b260a8d3b4544ecd0c8f ]
Fix to a problem observed when losing a FIN segment that does not
contain data. In such situations, TLP is unable to recover from
*any* tail loss and instead adds at least PTO ms to the
retransmission process, i.e., RTO = RTO + PTO.
