IpV6 interfaces, routes ... netlink?

[Maz]

Hi dee Ho peeps!

Long time no see
Simple question. Has anyone used netlink sockets via libnl? I should rewrite some old platform code which handles abstraction of some route configuations, interface up/down settings, alias interface configs etc for ipv4. The rewrite I am doing should enable same things for ipv6. I've browsed the web for quite a bit, and got the impression that preferred way for doing this is via netlink sockets. However I find netlink interface documenetation a bit hard o use.... Does anyone know if there's some examples, or some additioal ducumentation available?

Allright... Netlink interface itself is quite well documented. There's even an RFC describing the protocol quite well. My mistake was the attempt to use libnl... I believe libnl could be a great help, but I failed to find sufficient documentation... Eventually I used the netlink sockets without the libnl. Funny. Libnl was written to ease usage of netlink sockets - which admittably are errorprone interface. However I found it easier to use the netlink sockets than the libnl

Anyways, my problem is solved

Allright... One thing to ask.

Does anyone know if linux (2.6) really supports getting a route(s) matching given request attributes?

I've tried using NLM_F_MATCH flag in RTM_GETROUTE request for AF_INET6 family, and specified the RTA_DST, RTA_SRC, RTA_GATEWAY, RTA_OIF and RTA_PRIORITY attributes. However I get multipart reply with ALL ipv6 routes included - regardless the match to specified attributes...

So does anyone know if getting only routes matching given values is supported at all?
