* libxt_MARK: use guided option parserJan Engelhardt2011-04-131-70/+25

* iptables: do not print trailing whitespacesJan Engelhardt2011-01-311-10/+10
| | | | | | | | | | | | | | | | | 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
| | | | | | | Match and target parse functions now only get option characters they have defined themselves. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* src: use C99/POSIX typesJan Engelhardt2011-01-081-1/+1
| | | | | | "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 Engelhardt2010-07-231-1/+1
| | | | | | Try to inhibit copypasting old stuff. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* includes: header updatesJan Engelhardt2010-02-011-0/+5
| | | | | | | | | | | | Update the shipped Linux kernel headers from 2.6.33-rc6, as iptables's ipt_ECN.h for example references ipt_DSCP.h, which no longer exists. Since a number of old code pieces have been removed in the kernel in that fashion, the structs for older versions are moved into the .c file, to keep header updating simple.

* 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>
* extensions: collapse data variables to use multi-reg callsJan Engelhardt2009-06-261-30/+30

* extensions: use NFPROTO_UNSPEC for .family fieldJan Engelhardt2009-06-011-2/+2
| | | | | | | | 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>
* extensions: add const qualifiers in print/save functionsJan Engelhardt2009-05-261-2/+2

* libxtables: prefix exit_error to xtables_errorJan Engelhardt2009-02-211-2/+2
| | | | 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>
* libxtables: prefix/order - param_actJan Engelhardt2009-01-301-4/+4
| | | | | | | | Changes: exittype -> xtables_exittype P_* -> XTF_* flags Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* libxtables: prefix/order - strtouiJan Engelhardt2009-01-271-2/+2
| | | | | | This commit also throws out the redundant string_to_number_*. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* extensions: use UINT_MAX constants over open-coded bits (1/2)Jan Engelhardt2009-01-271-3/+3
| | | | | | ~0 depends on the sizeof(int), so it is better to use UINT32_MAX. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* mark: fix invalid iptables-save outputPablo Sebastian Greco2008-09-291-1/+1
| | | | | | | | | | When a neg mark is saved via iptables-save it is saved as !--mark, but this is not recognized by iptables-restore, just adding a space to the saved file to make it look like "! --mark" makes iptables-restore accept the file.

* src: Update commentsJan Engelhardt2008-09-011-4/+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>

* Correct the family member value of libxt_mark revision 1Jan Engelhardt2008-04-061-1/+1
| | | | | libxt_mark rev1 used AF_INET6 in the class structure where it should have used AF_INET.

* Unique symbols 1/6Jan Engelhardt2007-10-041-28/+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>

* Remove the .next=NULL field. This is automatically initialized to zero.Jan Engelhardt2007-07-301-2/+0
| | | | | | | I've kept .print=NULL and .save=NULL so it stands out (since iptables will do the print/save then). Signed-off-by: Jan Engelhardt <jengelh@gmx.de>
