* netfilter: xt_NFLOG: don't call nf_log_packet in NFLOG module.Eric Leblond2008-11-041-2/+3
| | | | | | | | | | This patch modifies xt_NFLOG to suppress the call to nf_log_packet() function. The call of this wrapper in xt_NFLOG was causing NFLOG to use the first initialized module. Thus, if ipt_ULOG is loaded before nfnetlink_log all NFLOG rules are treated as plain LOG rules. Signed-off-by: Eric Leblond <eric@inl.fr> Signed-off-by: Patrick McHardy <kaber@trash.net>

* [NETFILTER]: x_tables: add NFLOG targetPatrick McHardy2006-12-031-0/+86
Add new NFLOG target to allow use of nfnetlink_log for both IPv4 and IPv6. Currently we have two (unsupported by userspace) hacks in the LOG and ULOG targets to optionally call to the nflog API. They lack a few features, namely the IPv4 and IPv6 LOG targets can not specify a number of arguments related to nfnetlink_log, while the ULOG target is only available for IPv4. Remove those hacks and add a clean way to use nfnetlink_log. Signed-off-by: Patrick McHardy <kaber@trash.net>
