* iptables: fix printing of line numbers with --line-numbers argHenrik Nordstrom2008-06-131-1/+1
| | | | | | | Commit bb34082d ("iptables --list chain rulenum") broke the line numbering, starting with printing an offset of 2. Signed-off-by: Patrick McHardy <kaber@trash.net>
* Make --set-counters (-c) accept comma separated countersHenrik Nordstrom2008-05-131-4/+7
| | | | | | | | | | | | Here is the --set-counters syntax patch requested earlier today making --set-counters (-c) accept comma separated counts. -c packets,bytes I have not updated the manpage to reflect this alternate syntax for the --set-counters (-c) option. Henrik Nordstrom <henrik@henriknordstrom.net>
* iptables --list chain rulenumHenrik Nordstrom2008-05-131-15/+31
| | | | | | | | | | | | Excent --list (and --list-rules) to allow selection of a single rule number iptables --list INPUT 4 iptables --list-rules INPUT 4 list rule number 4 in INPUT. Henrik Nordstrom <henrik@henriknordstrom.net>
* iptables --list-rules commandHenrik Nordstrom2008-05-131-15/+274
| | | | | | | | | | | | | | | | | | Adds iptables --list-rules (-S) command, acting as a combination of iptables --list and iptables-save. The primary motivation behind this patch is to get iptables-save like output capabilities in iptables-restore, allowing "iptables-restore -n" to be used as a consistent API to iptables for all kind of operations, not only blind updates.. As a bonus iptables also gets the capability of printing the rules as-is. This completely replaces the earlier patch which added the --rules option. Henrik Nordstrom <henrik@henriknordstrom.net>

* Introduces xtables match/target registrationYasuyuki KOZAKAI2007-07-241-310/+21
| | | | | | | | | | | | | | | | | | | | | | | - moves lib_dir to xtables.c - introduces struct pfinfo which has protocol family dependent infomations. - unifies load_ip[6]tables_ko() and moves them as load_xtables_ko() - introduces xt_{match,match_rule,target,tryload} and replaces ip[6]t_* with them - unifies following functions and move them to xtables.c - find_{match,find_target} - compatible_revision, compatible_{match,target}_revision - introduces xtables_register_{match,target} and make register_{match,target}[6] call them. xtables_register_* register ONLY matches/targets matched protocol family Some concepts: - source compatibility for libip[6]t_xxx.c with warning on compilation not binary compatibility. - binary compatibility between 2.4/2.6 kernel and iptables/ip6tables, of cause. - xtables is enough to support only one address family at runtime. Then xtables keeps infomations of only the focused address famiy in struct afinfo.

* reduce service_to_port duplication (Phil Oester <kernel@linuxace.com>)Phil Oester2006-07-201-0/+11
| | | | | The service_to_port function is used in a number of places, and could benefit from some centralization instead of being duplicated everywhere.
* iptables: handle cidr notation more sanely (Phil Oester <kernel@linuxace.com>)Phil Oester2006-07-101-0/+30
| | | | | | | | | | | | | | | | At present, a command such as iptables -A foo -s 10.10/16 will interpret 10.10/16 as 10.0.0.10/16, and after applying the mask end up with 10.0.0.0/16, which likely isn't what the user intended. Yet some people do expect 10.10 (without the cidr notation) to end up as 10.0.0.10. The below patch should satisfy all parties. It zero pads the missing octets only in the cidr case, leaving the IP untouched otherwise. This resolves bug #422

* cmdflags is used in cmd2char() to return the option for a command. It uses theHarald Welte2006-04-211-2/+1
| | | | | | bit position of the command mask as an index in the array. There's no entry for CMD_CHECK (0x0800U), so lookups for CMD_RENAME_CHAIN (0x1000U) index outside the array. (Closes: #463)
* Multiple matches of the same type can be specified on the commandline.Joszef Kadlecsik2006-03-031-7/+32
| | | | | | | | | | If two or more matches of the same type are detected then the options are assumed to be grouped in order to tell which option belongs to which match: ... -m foo ... <options0> ... -m foo ... <options1> ... Otherwise the commandline parsing is unmodified.

| | | | | | (Closes: #440). However, while this fixes the double-free, it still doesn't make iptables support two of the same matches within one rule. Apparently the last matchinfo is copied into all the previous matchinfo instances.
