* libxt_tcp: print space before, not after "flags:"Andreas Schwab2012-08-211-3/+2
| | | | | | | | tcp dpt:10flags: 0x17/0x02 ^^ Signed-off-by: Andreas Schwab <schwab@linux-m68k.org> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* libxt_tcp: always print the mask partsJan Engelhardt2011-08-201-3/+1
| | | | | | | | | 0xFF is unlikely to happen (given that ALL translates to 0x3F at most), but assuming that through magic, 0xFF was put into memory, iptables -S/iptables-save would ignore printing it, practically outputting just one argument to --tcp-flags which currently wants two.

* option: remove last traces of intrapositional negationJan Engelhardt2011-07-101-5/+0
| | | | | | Intrapositional negation was deprecated in 1.4.3. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

* iptables: do not print trailing whitespacesJan Engelhardt2011-01-311-18/+16
| | | | | | | | | | | | | | | | | 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: remove no longer necessary default: casesJan Engelhardt2011-01-081-3/+0

* src: use C99/POSIX typesJan Engelhardt2011-01-081-7/+7
| | | | | | "u_int" was a non-standardized extension predating C99 on some platforms. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* all: consistent syntax use in struct optionJan Engelhardt2010-07-231-8/+9
| | | | | | Try to inhibit copypasting old stuff. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* iptables/extensions: make bundled options work againJan Engelhardt2009-11-031-4/+4
| | | | | | | | | | | | | 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 Engelhardt2009-11-031-4/+4
| | | | | | | | | 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 Engelhardt2007-10-041-27/+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>
