Re: [mpls-linux-general] MPLS tunnels OOPsing kernel

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

I've seen this as well.  If the tunnel doesn't have a valid outgoing
label it tries to free the packet.  The opps occurs when freeing the packet.

To make sure this is the bug your getting hit with, check the contents of
/proc/net/mpls_tunnel after creating the tunnel and binding a label to it.
If you do not see a hex key (for the outgoing label) then the
tunnel <-> outgoing label binding didn't work.  Let me know what you see.
