[LARTC] netlink api

[LARTC] netlink api

[Morgan Nelson]

Hey all,

    I'm looking for more detailed info on the netlink api.  I've read
Andi Kleen's man pages (which describe themselves as lacking and
incomplete), rfc3549 -- Linux Netlink as an IP Services Protocol (which
was a nice general overview, but lacking in implementation detail), both
the iproute2/ip/tc source and the kernel source (which have no usable
documentation/comments), etc.

    Andi's man pages and rfc3549 were a great help in getting into the
basics of the netlink api, but I can't seem to find anything more
specific about the RTA TLV's, order of RTA's, which RTA's are optional,
which are required, etc.

    I'm thinking about writing a C++ library for netlink sockets, but I
don't necessarily want to spend the next 6 months wading through kernel
source to figure out that I had a single param wrong somewhere.  I'd
also be happy to compile a howto/tutorial/spec for others to use, if I
could just get the info.  Would anybody be interested in this?

    I'm more than happy to RTFM, but I need to know which fine manual to
read.  Please, any pointer would be greatly appreciated.

Morgan

Perhaps you have not found this yet?

I'm not sure that it answers your questions, but if you haven't run
across this document, it should help some.

Actually I had found that one, but it is a general overview, similar to 
rfc3549.  They have a touch different information, which complements the 
rfc, but neither are complete nor definitive.

This only makes me more determined to produce a netlink API doc, 
bringing all of the snips of info I can find together into one place.  
The rfc would probably be a good place to start a document like that, 
just fleshing out the detailed information it lacks.  I wonder what kind 
of copyright (etc.) issues that would entail.  The rfc is credited to 
four different authors, from four different companies.  Probably best to 
start from scratch.
