Subject: [PATCH AUTOSEL 4.19 44/81] ipvs: do not schedule icmp errors from tunnels
Date: Tue,  7 May 2019 01:35:15 -0400	[thread overview]
Message-ID: <20190507053554.30848-44-sashal@kernel.org> (raw)
In-Reply-To: <20190507053554.30848-1-sashal@kernel.org>

From: Julian Anastasov <ja@ssi•bg>

[ Upstream commit 0261ea1bd1eb0da5c0792a9119b8655cf33c80a3 ]

We can receive ICMP errors from client or from
tunneling real server. While the former can be
scheduled to real server, the latter should
not be scheduled, they are decapsulated only when
existing connection is found.

Fixes: 6044eeffafbe ("ipvs: attempt to schedule icmp packets")
