Hello networkers, I'd like to present for review and early testing (for brave ones) a new CARP implementation. The reason for this rewrite was that CARP protocol actually doesn't bring a new interface, but is a property of interface address. Rewriting it in this way helps to remove several hacks from incoming packet processing[1], simplifies some code, makes CARP addresses more sane from viewpoint of routing daemons such as quagga/zebra. It also brings support for a single redundant address on the subnet, the thing that is called "carpdev feature" in OpenBSD, long awaited in FreeBSD. More info and the patch itself is available here: http://people.freebsd.org/~glebius/newcarp/README I'm glad to here comments. -- Totus tuus, Glebius.
