* iptables/extensions: make bundled options work againJan Engelhardt2009-11-031-2/+2
| | | | | | | | | | | | | When using a bundled option like "-ptcp", 'argv[optind-1]' would logically point to "-ptcp", but this is obviously not right. 'optarg' is needed instead, which if properly offset to "tcp". Not all places change optind-based access to optarg; where look-ahead is needed, such as for tcp's --tcp-flags option for example, optind is ok.

* libxtables: hand argv to xtables_check_inverseJan Engelhardt2009-11-031-1/+1
| | | | | | | | | In going to fix NF bug #611, "argv" is needed in xtables_check_inverse to set "optarg" to the right spot in case of an intrapositional negation. References: http://bugzilla.netfilter.org/show_bug.cgi?id=611 Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

* libxtables: prefix/order - move check_inverse to xtables.cJan Engelhardt2009-01-301-1/+1
| | | | | | | This also adds a warning that intrapositional negation support is deprecated. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

* src: remove inclusion of iptables.hJan Engelhardt2008-11-201-1/+1
| | | | | | | | | iptables.h and ip6tables.h only include declarations internal to iptables (specifically iptables.c and ip6tables.c), as most of the public API has been moved to xtables.h a few months ago.

| | | | | | | | A number of comments are redundant, some outdated and others outright wrong in their own way. Remove and fixup. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Patrick McHardy <kaber@trash.net>

* Unique names 3/6Jan Engelhardt2007-10-041-23/+16
| | | | | | | | | | | Give symbols of libxt matches unique names (2/3). Adds unique prefixes to all functions (most of them - especially the hook functions) so that debugging programs can unambiguously map a symbol to an address. Also unifies the names of the xtables_match/xtables_target structs, (based upon libxt_connmark.c/libip6t_*.c). Signed-off-by: Jan Engelhardt <jengelh@gmx.de>
