Re: [mpls-linux-devel] Merging into the kernel?

[James R. L. <jl...@mi...>]

Before the holidays I had started down path to getting mpls-linux
into the kernel (again).  I emailed jamal.  My first goal is to get the
infrastructure that mpls-linux needs to interact with L3 protocols put
in place.  Im my implementation this is the 'shim' infrastructure (look
in the devel achieves for a patch I've posted).

I sent two patches for jamal's review, davem's technique for
interacting with L3 and the mpls-linux technique.  They are very similar,
if you ask me I think the mpls-linux method is more elegant and less
intrusive.

That is where we stand.  I'm sure jamal forgot about it with the holidays
and all.  I plan on picking up this task again soon.  I was trying to get
1.950 finished (quagga support is broken still), but there is not reason
this process can't be done at the same time.

So how can others help?  Review the code.  Test the code.  In particular
the locking scheme (RCU) needs to be reviewed.  In addition there is
some known issues with the netdevice notification handler (the list of NHLFE
is not being maintained correctly with respect to instructions, add/delete,
and device changes).  There was a bug report posted to general late last
summer that had some details.
