* src: introduce struct xt_xlate_{mt,tg}_paramsPablo Neira Ayuso2016-07-251-3/+3
| | | | | | | | This structure is an extensible containers of parameters, so we don't need to propagate interface updates in every extension file in case we need to add new parameters in the future. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* extensions: libipt_REJECT: Avoid to print the default reject with value in ↵Laura Garcia Liebana2016-03-171-1/+3
| | | | | | | | | | | | | | | | | | | the translation Avoid to print the reject with value in the translation when the value is the default. Before this patch: $ sudo iptables-translate -A FORWARD -p TCP --dport 22 -j REJECT nft add rule ip filter FORWARD tcp dport 22 counter reject with icmp type port-unreachable After this patch: $ sudo iptables-translate -A FORWARD -p TCP --dport 22 -j REJECT nft add rule ip filter FORWARD tcp dport 22 counter reject Signed-off-by: Laura Garcia Liebana <nevola@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* iptables-translate: pass ipt_entry and ip6t_entry to ->xlate()Pablo Neira Ayuso2016-03-091-1/+1
| | | | | | | The multiport match needs it, this basically leaves ->xlate() indirection with almost the same interface as ->print(). Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* extensions: rename xt_buf to xt_xlatePablo Neira Ayuso2016-02-161-3/+3
| | | | | | | Use a more generic name for this object to prepare the introduction of other translation specific fields. Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* extensions: libipt_REJECT: Add translation to nftShivani Bhardwaj2016-02-161-2/+45
| | | | | | | | | | | | | | | | | | Add translation for target REJECT to nftables. Examples: $ sudo iptables-translate -A FORWARD -p TCP --dport 22 -j REJECT nft add rule ip filter FORWARD tcp dport 22 counter reject with icmp type port-unreachable $ sudo iptables-translate -A FORWARD -p TCP --dport 22 -j REJECT --reject-with icmp-net-unreachable nft add rule ip filter FORWARD tcp dport 22 counter reject with icmp type net-unreachable $ sudo iptables-translate -A FORWARD -p TCP --dport 22 -j REJECT --reject-with tcp-reset nft add rule ip filter FORWARD tcp dport 22 counter reject with tcp reset Signed-off-by: Shivani Bhardwaj <shivanib134@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* libip[6]t_REJECT: use guided option parserJan Engelhardt2011-04-061-32/+26

* iptables: do not print trailing whitespacesJan Engelhardt2011-01-311-2/+2
| | | | | | | | | | | | | | | | | 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 Engelhardt2011-01-081-2/+0
| | | | | | | Match and target parse functions now only get option characters they have defined themselves. Signed-off-by: Jan Engelhardt <jengelh@medozas.de>

* 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: remove unwanted/add needed includes for IPv4 extsJan Engelhardt2009-02-211-1/+0
| | | | | | | Most touched files do not use anything from ip_tables.h, so remove that #include. multiport instead, does need it (ipt_entry). Signed-off-by: Jan Engelhardt <jengelh@medozas.de>
* 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>
* src: remove inclusion of iptables.hJan Engelhardt2008-11-201-1/+1
| | | | | | | | | iptables.h and ip6tables.h only include declarations internal to iptables (specifically iptables.c and ip6tables.c), as most of the public API has been moved to xtables.h a few months ago. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Patrick McHardy <kaber@trash.net>
* src: use NFPROTO_ constantsJan Engelhardt2008-11-181-1/+1
| | | | | | | | Resync netfilter.h from the latest kernel and make use of the new NFPROTO_ constants that have been introduced. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Signed-off-by: Patrick McHardy <kaber@trash.net>
* src: Update commentsJan Engelhardt2008-09-011-8/+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>

* Unique names 4/6Jan Engelhardt2007-10-041-22/+16
| | | | | | | | | | | Give symbols of libxt targets unique names (2/3). 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>
* Delete empty ->final_check() functionsJan Engelhardt2007-10-041-6/+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>
