* | iptables: allow for help-less extensionsJan Engelhardt2009-06-265-40/+53
| | | | | | | | | | | | | | This is for extensions that do not take any options, and which subsequently do not offer any help text either. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* | iptables: allow for parse-less extensionsJan Engelhardt2009-06-262-8/+10
| | | | | | | | | | | | This means we can do some code removal in extensions. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

* | libiptc: split v4 and v6Jan Engelhardt2009-06-261-7/+12
| | | | | | | | | | | | | | The split can save some diskspace for constrained systems running which are only running one protocol. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

| * manpages: markup correctionsJan Engelhardt2009-06-105-26/+25
| | | | | | | | | | | | | | | | The manpage of xt_cluster and xt_recent had some unclosed tags. Backslashes in commands are also not wanted because manpages are a freeform, automatically-wrapped text. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
| * iptables: close open file descriptorsJan Engelhardt2009-06-105-0/+8
| | | | | | | | | | | | | | Just for correctness, close some file descriptors that were opened. (E.g. ip6tables-save reading from procfs files.) Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
| * libxt_connlimit: initialize v6_maskkd6lvw2009-06-101-1/+3
| | | | | | | | | | | | | | | | | | | | When converting "--connlimit-mask $bits" to a 128-bit v6 mask, the code uses a left shift on v6_mask[n]. This requires v6_mask to be filled with all one-bits beforehand, but this initialization was not done.

* | Updated set/SET match and target to support multiple ipset protocols.Jozsef Kadlecsik2009-06-115-44/+65
|/ | | | | | | | | | | By checking the protocol version of the kernel part, the sockopt type of ipset protocols are all supported. Forward compatibility with the netlink based protocol is missing. The --set option of the set match is replaced by --match-set to avoid clashing with the recent match, but the old option is also kept. Manpages are updated, references to bindings removed.

* extensions: use NFPROTO_UNSPEC for .family fieldJan Engelhardt2009-06-0117-19/+19
| | | | | | | | This constant would be the designated one for the .family field; it also, given recent changes, makes grep for NFPROTO_UNSPEC work to finally recollect all manpages. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* build: fix manpage collectionJan Engelhardt2009-06-011-1/+4
| | | | | | | | | | | | Florian Westphal points out that v1.4.3.2-9-gc304d77 greps for the keyword in the wrong file, and that files with NFPROTO_UNSPEC are skipped. This patch corrects that part, and makes `make` now output the manpages it collected. Reported-by: Florian Westphal <fw@strlen.de> Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

* xtables: fix segfault if incorrect protocol name is usedPablo Neira Ayuso2009-05-121-0/+3
| | | | | | | | | | | | | | | | This patch fixes a segfault that can be triggered if you use an incorrect protocol, e.g. # iptables -I PREROUTING -t nat -p lalala --dport 21 -j DNAT --to 192.168.1.2:21 Segmentation fault With this patch: # iptables -I PREROUTING -t nat -p lalala --dport 21 -j DNAT --to 192.168.1.2:21 iptables v1.4.3.2: unknown protocol `lala' specified Try `iptables -h' or 'iptables --help' for more information Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* libxt_conntrack: properly output negation symbolJan Engelhardt2009-04-051-4/+4
| | | | | | | | | Because the wrong flag was checked, the "!" was either wrongly printed, or not printed at all. This was broken since v1.4.0-29-ga8ad34c. Reported-by: Steven Jan Springl <steven@springl.ukfsn.org> Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* CLASSIFY: document non-standard interpretation behaviorJan Engelhardt2009-04-042-2/+3

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch combines the two referenced ones by Peter. I did a quick extra audit to spot and fix the missing ip6tables parts. (People like to forget ip6tables it seems.) Extension modules were, to the best of my knowledge, already audited in v1.4.3-rc1-10-gcea9f71.

| * build: add configure option to disable ip6tablesJan Engelhardt2009-04-033-4/+13
| | | | | | | | | | | | | | | | This also skips building the IPv6 extensions. It does not #ifdef out all code however, I think that would make it too ugly. Inspired-by: http://bugzilla.netfilter.org/show_bug.cgi?id=560 Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

| * libxtables: reorder .version memberJan Engelhardt2009-04-032-4/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | When the structure's layout changes, as it did between v1.4.1 and v1.4.2, trying to compare the version string makes iptables segfault while it tries to determine whether the module is compatible in the first place. By moving the member to a known offset in the struct and keeping it there, objects (both iptables and 3rd party) compiled from this commit onwards will avoid the segfault.
