Subject: Re: [PATCH v3] net: add a sysctl to reflect the fwmark on replies

From: Lorenzo Colitti <>
Date: Tue,  8 Apr 2014 08:58:51 +0900

> Kernel-originated IP packets that have no user socket associated
> with them (e.g., ICMP errors and echo replies, TCP RSTs, etc.)
> are emitted with a mark of zero. Add a sysctl to make them have
> the same mark as the packet they are replying to.
> This allows an administrator that wishes to do so to use
> mark-based routing, firewalling, etc. for these replies by

> Tested using user-mode linux:
>  - ICMP/ICMPv6 echo replies and errors.
>  - TCP RST packets (IPv4 and IPv6).
