[mpls-linux-general] ldp_portable + Quagga 0.96.5 + IPv6

[Andre G. <an...@gr...>]

Hi,

I'm trying to install mpls-linux, which works quite smoothly. But when I
came to quagga, quite a few problems arose.

I took quagga-mpls and quagga from the p4 depot, ran diff over them and
patched a Quagga 0.96.5 (Debian Source Package), which worked with some
minor tweaks.=20

After I started mplsd, the problems began. Mplsd doesn't check the
address family of addresses assigned to the interfaces, leading to IPv6
addresses being misinterpreted. So I hacked some checks for AF_INET.=20

After that, I get segfaults on a 'write file' after I enabled 'mpls ldp'
and an infinite loop on
mpls ldp
 lsr-id <addr>

As both occur at some MPLS_LIST-handling, I suspect the problem to be
somewhere inside it.
Is someone with more insight to the code able to reproduce these
problems or will I have to debug it myself?

I'd be pleased to get quagga-ldp running, but my time to dig inside the
40k lines of code is rather limited. :/

I have not worked on quagga-ldp for sometime.  I'm focusing my work
on quagga-mpls, which implements a proper MPLS framework for quagga.
I have just started the process of converting the mplsd code to be
LDP specific.  If you are interested in assisting with this work grab
the latest version of quagga-mpls and ldp-portable and start hacking on
the ldpd directory.

An updated list of directories in the depot would be helpful, then. I
just started the sync. I'll see if I get some patches out.

What do you think is the state of your changes? Will I be able to get
something running out of the box?

No.  Not even linking correctly yet.  Lots of work to be done.
