From 866476f323465a8afef10b14b48d5136bf5c51fe Mon Sep 17 00:00:00 2001 From: Kristian Evensen Date: Wed, 24 Dec 2014 09:57:10 +0100 Subject: [PATCH] netfilter: conntrack: Flush connections with a given mark This patch adds support for selective flushing of conntrack mappings. By adding CTA_MARK and CTA_MARK_MASK to a delete-message, the mark (and mask) is checked before a connection is deleted while flushing. Configuring the flush is moved out of ctnetlink_del_conntrack(), and instead of calling nf_conntrack_flush_report(), we always call nf_ct_iterate_cleanup(). This enables us to only make one call from the new ctnetlink_flush_conntrack() and makes it easy to add more filter parameters. Filtering is done in the ctnetlink_filter_match()-function, which is also called from ctnetlink_dump_table(). ctnetlink_dump_filter has been renamed ctnetlink_filter, to indicated that it is no longer only used when dumping conntrack entries. Moreover, reject mark filters with -EOPNOTSUPP if no ct mark support is available. Signed-off-by: Kristian Evensen Signed-off-by: Pablo Neira Ayuso --- Reading git-format-patch failed
