> Add a new optional conntrack action attribute OVS_CT_ATTR_EVENTMASK, > which can be used in conjunction with the commit flag > (OVS_CT_ATTR_COMMIT) to set the mask of bits specifying which > conntrack events (IPCT_*) should be delivered via the Netfilter > netlink multicast groups. Default behavior depends on the system > configuration, but typically a lot of events are delivered. This can be > very chatty for the NFNLGRP_CONNTRACK_UPDATE group, even if only some > types of events are of interest. > > Netfilter core init_conntrack() adds the event cache extension, so we > only need to set the ctmask value. However, if the system is > configured without support for events, the setting will be skipped due > to extension not being found. > > Signed-off-by: Jarno Rajahalme <ja...@ovn.org> > Reviewed-by: Greg Rose <gvrose8...@gmail.com> > Acked-by: Joe Stringer <j...@ovn.org> Applied.
