From d954777324ffcba0b2f8119c102237426c654eeb Mon Sep 17 00:00:00 2001 From: Holger Eitzenberger Date: Mon, 28 Oct 2013 14:42:33 +0100 Subject: [PATCH] netfilter: xt_NFQUEUE: fix --queue-bypass regression V3 of the NFQUEUE target ignores the --queue-bypass flag, causing packets to be dropped when the userspace listener isn't running. Regression is in since 8746ddcf12bb26 ("netfilter: xt_NFQUEUE: introduce CPU fanout").
