From 0975764684487bf3f7a47eef009e750ea41bd514 Mon Sep 17 00:00:00 2001 From: Julian Anastasov Date: Mon, 11 Jun 2018 02:02:54 +0300 Subject: ipv6: allow PMTU exceptions to local routes IPVS setups with local client and remote tunnel server need to create exception for the local virtual IP. What we do is to change PMTU from 64KB (on "lo") to 1460 in the common case. Suggested-by: Martin KaFai Lau Fixes: 45e4fd26683c ("ipv6: Only create RTF_CACHE routes after encountering pmtu exception") Fixes: 7343ff31ebf0 ("ipv6: Don't create clones of host routes.")
