[mpls-linux-general] /proc/net/mpls_out bug with Zebra and LDP (mplsd)

Hi all,
is there someone how can help me with the wrong interface in =
/proc/net/mpls_out?
This is my small testseup (UML) - everything latest CVS release,
all networks are /24 and starting with '10.',=20
all MAC-Addrs=3D'00:00:IP'
eth0 eth1 eth1 eth2 eth1 eth2
HOST------LSR1----------LSR3-----------LSR6---------next LSR not started
0.30.2 1.2.1 1.2.3 3.6.3 3.6.6 6.10.6
LSR3 and LSR6 have also a tuntap interface to the host system =
(10.0.23/24 and 10.0.26/24)
i add a additional debug line in mpls_utils.c on LSR3 for a further=20
test, and found:
Mar 9 12:41:15 LSR-3 kernel: : push label Label GEN 10003
Mar 9 12:41:16 LSR-3 kernel: mpls_make_dst: enter
!! -> Mar 9 12:41:16 LSR-3 kernel: mpls_make_dst: dev_get_by_index(ifi) =
=3D 3
Mar 9 12:41:16 LSR-3 kernel: mpls_dst_hold: enter
Mar 9 12:41:16 LSR-3 kernel: mpls_dst_hold: new count 1
Mar 9 12:41:16 LSR-3 kernel: mpls_dst_hold: exit
Mar 9 12:41:16 LSR-3 kernel: mpls_make_dst: exit(a3a5c8a0)
and a small test program found:
LSR-3:/var/log$ cat /proc/net/mpls_out
0x00000002 0/0/0 2 PUSH(gen 10003) SET(eth1,10.3.6.6)
LSR-3:/var/log$ /tmp/getifi eth1
index: 3 name: eth1
so, the parameter ifi to
static struct mpls_dst *mpls_make_dst(unsigned int ifi,struct sockaddr =
*nh,
from
/* NOTE: mpls_make_dst holds the dev,
* so release the hold from dev lookup*/
md =3D =
mpls_make_dst(mir->mir_instruction[i].mir_data.set.mni_if,
&mir->mir_instruction[i].mir_data.set.mni_addr,moi);
dev_put(dev);
in mpls_utils.c is wrong...
why?
in the trace-all dump from a test before i found on LSR3:
> ldp_label_mapping_with_xc: exit
> OUT: Processing: 0a060a00/24 via eth2/0a030606
> EXIT: ldp_label_mapping_initial_callback
which is a correct setting:
10.6.10.0/24 via eth2 of LSR3 to 10.3.6.6 (this is eth1 of LSR6)
but mpls_out says eth1 of LSR3 ...?=20
who is modifying the interface between mplsd and the kenel?
thx in advance,
markus
btw, is there a /proc interface to the 'dev_get_by_index(ifi)' function?
