2008-01-28[NETFILTER]: Rename ipt_iprange to xt_iprangeJan Engelhardt
This patch moves ipt_iprange to xt_iprange, in preparation for adding IPv6 support to xt_iprange. Signed-off-by: Jan Engelhardt <jengelh@computergmbh.de> Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[NETFILTER]: Remove some EXPERIMENTAL dependenciesPatrick McHardy
Most of the netfilter modules are not considered experimental anymore, the only ones I want to keep marked as EXPERIMENTAL are: - TCPOPTSTRIP target, which is brand new. - SANE helper, which is quite new. - CLUSTERIP target, which I believe hasn't had much testing despite being in the kernel for quite a long time. - SCTP match and conntrack protocol, which are a mess and need to be reviewed and cleaned up before I would trust them.

2008-01-28[NETFILTER]: Add CONFIG_NETFILTER_ADVANCED optionPatrick McHardy
The NETFILTER_ADVANCED option hides lots of the rather obscure netfilter options when disabled and provides defaults (M) that should allow to run a distribution firewall without further thinking. Defaults to 'y' to avoid breaking current configurations. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>

2008-01-28[NETFILTER]: remove NF_CONNTRACK_ENABLED optionPatrick McHardy
Remove the NF_CONNTRACK_ENABLED option. It was meant for a smoother upgrade to nf_conntrack, people having reconfigured their kernel at least once since ip_conntrack was removed will have the NF_CONNTRACK option already set. People upgrading from older kernels have to reconfigure a lot anyway. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
2008-01-28[NETFILTER]: x_tables: add rateest matchPatrick McHardy
Add rate estimator match. The rate estimator match can match on estimated rates by the RATEEST target. It supports matching on absolute bps/pps values, comparing two rate estimators and matching on the difference between two rate estimators. This is what I use to route outgoing data connections from a FTP server over two lines based on the available bandwidth: # estimate outgoing rates iptables -t mangle -A POSTROUTING -o eth0 -j RATEEST --rateest-name eth0 \ --rateest-interval 250ms \ --rateest-ewma 0.5s iptables -t mangle -A POSTROUTING -o ppp0 -j RATEEST --rateest-name ppp0 \ --rateest-interval 250ms \ --rateest-ewma 0.5s # mark based on available bandwidth iptables -t mangle -A BALANCE -m state --state NEW \ -m helper --helper ftp \ -m rateest --rateest-delta \ --rateest1 eth0 \ --rateest-bps1 2.5mbit \ --rateest-gt \ --rateest2 ppp0 \ --rateest-bps2 2mbit \ -j CONNMARK --set-mark 0x1 iptables -t mangle -A BALANCE -m state --state NEW \ -m helper --helper ftp \ -m rateest --rateest-delta \ --rateest1 ppp0 \ --rateest-bps1 2mbit \ --rateest-gt \ --rateest2 eth0 \ --rateest-bps2 2.5mbit \ -j CONNMARK --set-mark 0x2 iptables -t mangle -A BALANCE -j CONNMARK --restore-mark Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.

2008-01-28[NETFILTER]: x_tables: add RATEEST targetPatrick McHardy

2008-01-28[NETFILTER]: IPv6 capable xt_TOS v1 targetJan Engelhardt
Extends the xt_DSCP target by xt_TOS v1 to add support for selectively setting and flipping any bit in the IPv4 TOS and IPv6 Priority fields. (ipt_TOS and xt_DSCP only accepted a limited range of possible values.)

2008-01-28[NETFILTER]: Merge ipt_TOS into xt_DSCPJan Engelhardt
Merge ipt_TOS into xt_DSCP. Merge ipt_TOS (tos v0 target) into xt_DSCP. They both modify the same field in the IPv4 header, so it seems reasonable to keep them in one piece. This is part two of the implicit 4-patch series to move tos to xtables and extend it by IPv6.

This is nf_conntrack_sane, a netfilter connection tracking helper module for the SANE protocol used by the 'saned' daemon to make scanners available via network.

2006-12-02[NETFILTER]: x_tables: add NFLOG targetPatrick McHardy
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.

2006-06-17[SECMARK]: Add CONNSECMARK xtables targetJames Morris
Add a new xtables target, CONNSECMARK, which is used to specify rules for copying security marks from packets to connections, and for copyying security marks back from connections to packets. This is similar to the CONNMARK target, but is more limited in scope in that it only allows copying of security marks to and from packets, as this is all it needs to do. A typical scenario would be to apply a security mark to a 'new' packet with SECMARK, then copy that to its conntrack via CONNMARK, and then restore the security mark from the connection to established and related packets on that connection.
