Subject: [PATCH 2.6.11 PKT_SCHED]: ipt action: add back pskb_expand_head call
Date: Fri, 04 Feb 2005 04:10:54 +0100 [thread overview]
Message-ID: <4202E7BE.6050606@trash.net> (raw)

Hi Dave,
Jamal asked me to add back the call to pskb_expand_head before 2.6.11.
This fixes a regression caused by my tc action cleanup patches, the
tc actions most not replace packets, so it must prevent netfilter from
doing so.
Regards
Patrick
