* libxt_hashlimit: use a more obvious expiry value by defaultJan Engelhardt2011-06-221-16/+41
| | | | | | | | | | Due to the previous default expiry of 10 sec, "--hashlimit 1/min" would allow matching up to 6/min if a properly timed. To do what the user expects, the minimum expiry must equal the selected time quantum however. Cc: Jan Rovner <jan.rovner@diadema.cz> Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

* extensions: remove redundant init functionsJan Engelhardt2011-02-191-1/+0
| | | | | | The main program already zeroes the per-extension data block. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* iptables: do not print trailing whitespacesJan Engelhardt2011-01-311-38/+38
| | | | | | | | | | | | | | | | | 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.

* libxt_hashlimit: always print burst valueJan Engelhardt2010-06-241-4/+2
| | | | | | | | iptables -L lists the burst value, and so should iptables -S. I was certainly surprised to see it gone even when explicitly specifying --hashlimit-burst 5 on the command line. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* iptables/extensions: make bundled options work againJan Engelhardt2009-11-031-8/+8
| | | | | | | | | | | | | 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 Engelhardt2009-11-031-8/+8
| | | | | | | | | 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>

* Unique symbols 1/6Jan Engelhardt2007-10-041-32/+27
| | | | | | | | | | | Give symbols of libxt matches unique names (1/3). 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.
