* extensions: include strings.h for the definition of ffs()Maciej Żenczykowski2020-04-281-0/+1

* libipt_ULOG: fix --ulog-cprangePablo Neira Ayuso2012-05-091-2/+2
| | | | | | | | | | | In 1f2474a libipt_ULOG: use guided option parser. A bug has been accidentally introduced in --ulog-cprange, limiting possible values from 1 to 50. However, that limit should be applied to --ulog-qthreshold. Reported-by: Gaurav Sinha <vgsinha@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>

* iptables: do not print trailing whitespacesJan Engelhardt2011-01-311-9/+9
| | | | | | | | | | | | | | | | | 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.

* libxtables: hand argv to xtables_check_inverseJan Engelhardt2009-11-031-2/+2
| | | | | | | | | 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>
* extensions: remove unwanted/add needed includes for IPv4 extsJan Engelhardt2009-02-211-1/+0
| | | | | | | Most touched files do not use anything from ip_tables.h, so remove that #include. multiport instead, does need it (ipt_entry). 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.

* src: use regular includesJan Engelhardt2008-09-011-1/+1

* Unique names 4/6Jan Engelhardt2007-10-041-19/+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>
