Subject: Re: [PATCH net v2 0/2] net: ipv4: fixes for PMTU when link MTU
 changes

From: Sabrina Dubroca <sd@...asysnail.net>
Date: Tue,  9 Oct 2018 17:48:13 +0200

> The first patch adapts the changes that commit e9fa1495d738 ("ipv6:
> Reflect MTU changes on PMTU of exceptions for MTU-less routes") did in
> IPv6 to IPv4: lower PMTU when the first hop's MTU drops below it, and
> raise PMTU when the first hop was limiting PMTU discovery and its MTU
> is increased.
> 
> The second patch fixes bugs introduced in commit d52e5a7e7ca4 ("ipv4:
> lock mtu in fnhe when received PMTU < net.ipv4.route.min_pmtu") that
> only appear once the first patch is applied.
> 
> Selftests for these cases were introduced in net-next commit
> e44e428f59e4 ("selftests: pmtu: add basic IPv4 and IPv6 PMTU tests")
> 
> v2: add cover letter, and fix a few small things in patch 1
