| * libxt_time: add support to ignore day transitionFlorian Westphal2012-09-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, if you want to do something like: "match Monday, starting 23:00, for two hours" You need two rules, one for Mon 23:00 to 0:00 and one for Tue 0:00-1:00. The rule --weekdays Mo --timestart 23:00 --timestop 01:00 looks correct, but it will first match on monday from midnight to 1 a.m. and then again for another hour from 23:00 onwards. This permits userspace to explicitly ignore the day transition and match for a single, continuous time period instead.

| | | | | | | | | | | | | | | | | | | | | This patch allows for match names listed on the command line to be rewritten to new names and revisions, like we did for targets before. Signed-off-by: Jan Engelhardt <jengelh@inai.de>
| * | iptables: support for target aliasesJan Engelhardt2012-09-271-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows for target names listed on the command line to be rewritten to new names and revisions. As before, we will pick a revision that is supported by the kernel - now including real_name in the search. This gives us the possibility to test for many action names.

* include: add missing linux/netfilter_ipv4/ip_queue.hPablo Neira Ayuso2012-08-031-0/+72
| | | | | | | | | | | | | | | This patch fixes compilation of libipq with headers from Linux kernel 3.5: In file included from libipq.c:34:0: ../include/libipq/libipq.h:33:43: fatal error: linux/netfilter_ipv4/ip_queue.h: No such file or directory ip_queue is gone since Linux kernel 3.5. However, you can still use new iptables versions with old Linux kernels. We have to keep libipq in this tree for a while (1.5-2 years should be OK).

* extensions: add HMARK targetHans Schillstrom2012-07-141-0/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The target allows you to set mark packets based Jenkins' hash calculation: h(t, rnd) = x mark = (x % mod) + offset where: * t is a tuple that is used for the hashing: t = [ src, dst, proto, sport, dport ] Note that you can customize the tuple, thus, removing some component that you don't want to use for the calculation. You can also use spi instead of sport and dport, btw. * rnd is the random seed that is explicitly passed via --hmark-rnd * mod is the modulus, to determine the range of possible marks * offset determines where the mark starts from This target only works for the "raw" and "mangle" tables. This can be used to distribute flows between a cluster of systems and uplinks. Initially based on work from Hans Schillingstrom. Pablo took it over and introduced several improvements.

* libxtables: add xtables_ip[6]mask_to_cidrPablo Neira Ayuso2012-07-141-0/+2
| | | | | | | | | | | | | | This patch adds generic functions to return the mask in CIDR notation whenever is possible. This patch also simplifies xtables_ip[6]mask_to_numeric, that now use these new two functions. This patch also bumps libxtables_vcurrent and libxtables_vage since we added a couple new interfaces (thanks to Jan Engelhardt for his little reminder on this).

* libxt_CT: add --timeout optionPablo Neira Ayuso2012-04-021-0/+12
| | | | | | | | | | | | | | | | | | | | This patch adds the --timeout option to allow to attach timeout policy objects to flows, eg. iptables -I PREROUTING -t raw -s 1.1.1.1 -p tcp \ -j CT --timeout custom-tcp-policy You need the nfct(8) tool which is available at: http://git.netfilter.org/cgi-bin/gitweb.cgi?p=nfct.git To define the cttimeout policies. Example of usage: nfct timeout add custom-tcp-policy inet tcp established 1000 The new nfct tool also requires libnetfilter_cttimeout: http://git.netfilter.org/cgi-bin/gitweb.cgi?p=libnetfilter_cttimeout.git Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* extensions: add nfacct matchPablo Neira Ayuso2012-03-271-0/+17
| | | | | | | | | | | | | | This patch provides the user-space iptables support for the nfacct match. This can be used as it follows: nfacct add http-traffic iptables -I INPUT -p tcp --sport 80 -m nfacct --nfacct-name http-traffic iptables -I OUTPUT -p tcp --dport 80 -m nfacct --nfacct-name http-traffic nfacct get http-traffic See also man nfacct(8) for more information.

* libxtables: use uintmax for xtables_strtoulJan Engelhardt2011-05-241-2/+2
| | | | | | | | | | | | | | | Addendum to 2305d5fb42fc059f38fc1bdf53411dbeecdb310b. I noticed that unsigned long long is not consistently used, for example, min/max are still just unsigned long, and strtoul is being called. Instead of changing it to unsigned long long, just use uintmax functions right away so this does not need size-related changing in the future.
