* ip6tables-save: Merge into iptables-save.cPhil Sutter2018-11-131-203/+0
| | | | | | | | | Both implementations were very similar already. Differences were mostly in which libiptc functions were called. Therefore introduce struct iptables_save_cb to point to the right functions for each variant. Signed-off-by: Phil Sutter <phil@nwl.cc> Signed-off-by: Florian Westphal <fw@strlen.de>
* xtables: add nf_tables vs. legacy postfix to version stringsFlorian Westphal2018-06-181-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | -V now yields: arptables vlibxtables.so.12 (nf_tables) ebtables 1.6.2 (nf_tables) ip6tables v1.6.2 (legacy) ip6tables v1.6.2 (nf_tables) ip6tables-restore v1.6.2 (nf_tables) ip6tables-save v1.6.2 (nf_tables) ip6tables-restore v1.6.2 (legacy) ip6tables-restore-translate v1.6.2 ip6tables-save v1.6.2 (legacy) ip6tables-translate v1.6.2 (nf_tables) iptables v1.6.2 (legacy) iptables v1.6.2 (nf_tables) iptables-restore v1.6.2 (nf_tables) iptables-save v1.6.2 (nf_tables) iptables-restore v1.6.2 (legacy) iptables-restore-translate v1.6.2 iptables-save v1.6.2 (legacy) iptables-translate v1.6.2 (nf_tables) This allows to see wheter "iptables" is using old set/getsockopt or new nf_tables infrastructure.

* iptables: Add file output option to iptables-saveOliver Ford2017-05-291-2/+20
| | | | | | | | | | | | | | | Adds an option to output the results of iptables-save, ip6tables-save, and xtables-save save to a file. Updates the man page with this new option. Uses the dup2 call to replace stdout with the specified file. Error output is unchanged. This is a feature requested by a Gentoo developer in Bugzilla #905.

* iptables-restore/save: exit when given an unknown optionVincent Bernat2017-04-191-0/+4
| | | | | | | | | | | | When an unknown option is given, iptables-restore should exit instead of continue its operation. For example, if `--table` was misspelled, this could lead to an unwanted change. Moreover, exit with a status code of 1. Make the same change for iptables-save. OTOH, exit with a status code of 0 when requesting help. Signed-off-by: Vincent Bernat <vincent@bernat.im> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
* iptables: Remove explicit static variables initalization.Varsha Rao2017-04-061-1/+1

| | | | | | | | | On glibc, <sys/errno.h> is a synomym for <errno.h>. <errno.h> is specified by POSIX, so use that. Fixes compilation error with musl libc Signed-off-by: Florian Westphal <fw@strlen.de>
