* extensions: add libxt_bpf extensionWillem de Bruijn2013-04-022-0/+186
| | | | | | | | | | | | | | | | | | Add user-space code to support the new BPF iptables extension. Pablo has mangled the original patch to: * include a copy of include/linux/netfilter/xt_bpf.h in the tree. * I have also remove the --bytecode-file option. The original proposal was to accept BPF code in a file in human readable format. Now, with the nfbpf_compile utility, it's very easy to generate the filter using tcpdump-like syntax. * I have remove the trailing comma in the backtick format, the parser works just fine for me here. * Fix error message if --bytecode is missing.

* Revert "build: resolve link failure for ip6t_NETMAP"Pablo Neira Ayuso2013-03-291-11/+7
| | | | | | | | | | | | | | | | | | This reverts commit 68e77a26111ee6b8f10c735a76891a7de6d57ee6. The use of libtool was introduced to resolve linking problems in NETMAP (IPv6 version), but that resulted in RPATH problems reported from distributors and warnings spotted by libtool at linking stage. Since (0ca548b libip6t_NETMAP: Use xtables_ip6mask_to_cidr and get rid of libip6tc dependency) fixed the NETMAP issue, let's roll back to our previous stage. A small conflicts in extensions/GNUmakefile.in has been resolved in this revert. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* build: resolve link failure for ip6t_NETMAPJan Engelhardt2013-01-021-8/+12
| | | | | | | | | | | | | | | | | | | | | | | | Link stage of libip6t_NETMAP failed since recently. CCLD libip6t_NETMAP.so /usr/lib64/gcc/x86_64-suse-linux/4.7/../../../../x86_64-suse-linux/bin/ld: cannot find -lip6tc libip6t_NETMAP.c uses the "ipv6_prefix_length" function from libip6tc.so; "-lip6tc" is used in the Makefile, but, the directory to it is not specified. Why does the link succeed for some people? Because /usr/lib(64)/libip6tc.so satisfies -lip6tc, but not all environments, especially those without iptables development files, have that file, hence this link error can happen. By suggestion of Mike Frysinger, this patch uses libtool to produce and link the plugins.

| * libxt_time: add support to ignore day transitionFlorian Westphal2012-09-302-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

However, on ├że olde RHEL 5's glibc-2.5, it only has "-D_POSIX_C_SOURCE=200112L". Explicitly draw in the definition of INFINITY by always defining _ISOC99_SOURCE. By doing this, we are moving off of the default set, so _BSD_SOURCE also needs to be explicitly set to get at IFNAMSIZ that is used in xt_hashlimit.h.
