Subject: [RFC PATCH 0/1] xtables: allow to monitor table update event
Date: Tue, 2 Oct 2012 15:06:10 +0200 [thread overview]
Message-ID: <1349183171-4136-1-git-send-email-nicolas.dichtel@6wind.com> (raw)
In-Reply-To: <1348501182-12470-1-git-send-email-nicolas.dichtel@6wind.com>
The following patch is an example of a userspace tools (in fact, iptables)
that use the new netlink API to monitor tables activity.
I will also send a patch against libnfnetlink to update linux includes with
this new feature.
Maybe another API can be used for this feature: adding a setsockopt() on an
iptc socket to enable monitoring. When a table is updated, a packet (built with
CMSG_* macro for example) can be sent over all sockets that monitor tables
acitivity (like km sockets in IPsec). I know that this socket was used only with
[g|s]etsockopt(), but this can avoid adding another netlink API.
Comments are welcome.
Regards,
Nicolas
