[mpls-linux-general] Mpls qos and segfault

[<ram...@wi...>]

Hi,

I have two questions:

1)---------

I downloaded kernel-2.6.9 and mpls-linux. I patched the kernel for mpls
support and iproute2 which gives mpls and tc. Now I booted with mpls
support. I want to know whether this iproute2 supports mpls Qos.

2)---------

i got segmentation fault while using mpls tool.
i added labelspace as follows

mpls labelspace add dev eth0 labelspace 0

mpls labelspace show=20

shows the labelspaces. after that the following ilm command gives
segfault.

mpls ilm add label gen 1000 labelspace 0

dmesg says=20


MPLS DEBUG net/mpls/mpls_ilm.c:146:mpls_ilm_dst_alloc: *Unable to find
protocol driver for 'AF_INET'* MPLS DEBUG
net/mpls/mpls_ilm.c:157:mpls_ilm_dst_alloc: exit Unable to handle kernel
NULL pointer dereference at virtual address 00000000  printing eip:
c0322e34
*pde =3D 00000000
Oops: 0000 [#1]
..............
..................

now what is the problem, how to rectify that error *Unable to find
protocol driver for 'AF_INET'

Thanks in advance

regards
Ramesh.s

Did you compile the MPLS IP support in the kernel? Or just the MPLS
support?

IIRC, you need to activate MPLS support and then MPLS IP support when
you configure the kernel (it's not done by default).
