From 1205e1fa615805c9efa97303b552cf445965752a Mon Sep 17 00:00:00 2001 From: Phil Oester Date: Sun, 1 Sep 2013 08:32:21 -0700 Subject: [PATCH] netfilter: xt_TCPMSS: correct return value in tcpmss_mangle_packet 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.
