* libxt_statistic: use guided option parserJan Engelhardt2011-05-091-88/+56

* libxt_statistic: increase precision on create and dumpJan Engelhardt2011-05-091-3/+4
| | | | | | | | | | | | | | | | | | | Currently, libxt_statistic only dumps the probability with a granularity of 1/1000000. Assuming only stuffed packets with 1440 bytes payload, this would match approximately every 1.341 GB, which is pretty low for a high-volume router. Trying to match any larger interval than that (e.g. 2 GB) will cause libxt_statistic to output "--probability 0.000000", and when restored, will cause it to never match again. Bump the dump precision to what xt_statistic can really do, and adjust the manpage to include a word about it. Furthermore, employ explicit rounding when reading the argument from the command line, because the previous implicit conversion would use truncation, which is not very exact.

* iptables: do not print trailing whitespacesJan Engelhardt2011-01-311-5/+5
| | | | | | | | | | | | | | | | | 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: use NFPROTO_UNSPEC for .family fieldJan Engelhardt2009-06-011-1/+1
| | | | | | | | This constant would be the designated one for the .family field; it also, given recent changes, makes grep for NFPROTO_UNSPEC work to finally recollect all manpages. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

* src: Update commentsJan Engelhardt2008-09-011-3/+0
| | | | | | | | A number of comments are redundant, some outdated and others outright wrong in their own way.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>

* Fix -Wshadow warnings and clean up xt_sctp.hJan Engelhardt2008-04-061-8/+15
| | | | | Note: xt_sctp.h is still not merged upstream in the kernel as of this commit. But a refactoring was really needed.

* Unique symbols 1/6Jan Engelhardt2007-10-041-29/+23
| | | | | | | | | | | 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. 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>
