From: Herbert Xu Date: Mon, 12 Jan 2009 00:06:02 +0000 (+0000) Subject: netfilter 02/09: bridge: Fix handling of non-IP packets in FORWARD/POST_ROUTING X-Git-Tag: v2.6.29-rc2~11^2~59 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=a2bd40ad3151d4d346fd167e01fb84b06f7247fc;p=linux-2.6-omap-h63xx.git netfilter 02/09: bridge: Fix handling of non-IP packets in FORWARD/POST_ROUTING Currently the bridge FORWARD/POST_ROUTING chains treats all non-IPv4 packets as IPv6. This packet fixes that by returning NF_ACCEPT on non-IP packets instead, just as is done in PRE_ROUTING. Signed-off-by: Herbert Xu Signed-off-by: Patrick McHardy Signed-off-by: David S.
