* libipt_MASQUERADE: use guided option parserJan Engelhardt2011-05-091-27/+21

* iptables: do not print trailing whitespacesJan Engelhardt2011-01-311-6/+4
| | | | | | | | | | | | | | | | | Due to the use of printf("foobar "), iptables emits spaces at the end-of-line, which looks odd to some users because it causes the terminal to wrap even if there is seemingly nothing to print. It may also have other points of annoyance, such as mailers interpreting a trailing space as an indicator that the paragraph continues when format=flowed is also on. And git highlights trailing spaces in red, so let's avoid :) Preexisting inconsistencies in outputting spaces in the right spot are also addressed right away.

* extensions: MASQUERADE: fix --to-ports parserDmitry V. Levin2010-05-201-16/+16
| | | | | | | | | | | Rewrite port range validator to use xtables_strtoui() and xtables_param_act(). Original check failed to recognize such port range errors as "1a-2" and "1-2a". Also, original parser erroneously denied using port 0, which is now allowed. Signed-off-by: Dmitry V. Levin <ldv@altlinux.org> Signed-off-by: Patrick McHardy <kaber@trash.net>
* 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.

* Unique names 4/6Jan Engelhardt2007-10-041-21/+16
| | | | | | | | | | | Give symbols of libxt targets 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>
