Subject: [PATCH] netfilter: xt_TCPMSS: correct return value in tcpmss_mangle_packet
Date: Sun, 1 Sep 2013 08:32:21 -0700 [thread overview]
Message-ID: <20130901153221.GB10125@linuxace.com> (raw)
[-- Attachment #1: Type: text/plain, Size: 399 bytes --]
In commit b396966c4 (netfilter: xt_TCPMSS: Fix missing fragmentation handling),
I attempted to add safe fragment handling to xt_TCPMSS. However, Andy Padavan
of Project N56U correctly points out that returning XT_CONTINUE in this
function does not work. The callers (tcpmss_tg[46]) expect to receive a value
of 0 in order to return XT_CONTINUE.
