| * iptables: link against libnetfilter_conntrackJan Engelhardt2013-08-231-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linking currently fails in --enable-static case: ../extensions/libext.a(libxt_connlabel.o): In function `connlabel_get_name': iptables/extensions/libxt_connlabel.c:57: undefined reference to `nfct_labelmap_get_name' [..] It's libxtables.la(libxt_connlabel.o) using libnetfilter_conntrack. If libnetfilter_conntrack is not found, @libnetfilter_conntrack_CFLAGS@ and @libnetfilter_conntrack_LIBS@ (and their ${} ones) should be empty, therefore producing no harm to include unconditionally.

|/ | | | | | | | | | | | | | | | | | | | | xt_socket module can be a nice replacement to conntrack module in some cases (SYN filtering for example) But it lacks the ability to match the 3rd packet of TCP handshake (ACK coming from the client).

* extensions: libxt_connlabel: use libnetfilter_conntrackFlorian Westphal2013-07-163-115/+33
| | | | | | | | | | | | | | | | | Pablo suggested to make it depend on lnf-conntrack, and get rid of the example config file as well. The problem is that the file must be in a fixed path, /etc/xtables/connlabel.conf, else userspace needs to "guess-the-right-file" when translating names to their bit values (and vice versa). Originally "make install" did put an example file into /etc/xtables/, but distributors complained about iptables ignoring the sysconfdir. So rather remove the example file, the man-page explains the format, and connlabels are inherently system-specific anyway. Signed-off-by: Florian Westphal <fw@strlen.de>

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.

| | | | | | | | | | | | | | | | | | 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>
