No, we now have counters and great Diffserv support. 

We still need to patch the kernel for two reasons:
* prevent dsmark from copying the DSCP to tcindex (is done by
EXP2TCINDEX)
* a hack to map DiffServ over IP and DiffServ over MPLS traffic to the
same queue ("tc filter" insists on having a protocol field)

But I dont think they belong in your MPLS patch, do they? These issues
only arise if you want to have a mixed Diffserv over IP and MPLS. (And
you really want that because you want a separate control packet(=IP)
queue.)

It sounds interesting to have direct access to the routing tables and
even more powerfull the link state database. (I have written papers
about and developed a scheme where you can reroute LSP very fast based
on the topology information called FTCR). Also having the same CLI for
RSVP and OSPF also seems like a huge plus. 

Problem is that my time is pretty limited and first on my to do list is
getting L-LSP support more or less stable and released.

Great, let me suggest that you wait for the 0.70-rc1 release which comes
with MPLS 1.160.

Yes, you too, we really appreciate your work.

Thank you for point this out.  I will fix it.

Do you have any additional code that you add to the base mpls-linux
kernel patch?  I know at one point there were some additions that dsMPLS
needed.  Is this still the case?

Have you tried creating a zebra front end to your RSVP-TE implementation?
Would you be interested in such an endevor?  I have a decent start on a
front end to my LDP implementation and the beginings of a static LSP
implementation.  I think I have worked out many of the issues with adding
"MPLS" routes to the zebra RIB, and having BGP or other routes resolve
their nexthops correctly.

Either way, one of these days I'll get around to setting up your code and
playing around with it :-)

Keep up the good work.

[mpls-linux-general] MPLS-Linux 1.160 and kernel integration

[<pim...@in...>]

Hi James,

I just tried MPLS-Linux 1.160 with the RSVP daemon and it seems that
things are stable now (I havent been able to crash the kernel so far).
Joy!

Not that I rely on it but:
ipt_MPLS.c does not compile because it uses a two argument
mpls_set_nexthop()
/usr/src/mpls-linux-1.1/patches# grep mpls_set_nexthop linux-kernel.diff
+void mpls_set_nexthop(struct rtable*, struct fib_result*, u32);
+               mpls_set_nexthop((*pskb)->dst,mplsinfo->key); <---
offending line
+                       mpls_set_nexthop(rt,res,itag);

About the kernel integration: we (as in dsMPLS) dont need additional
features.
Note that the code freeze for 2.5/2.6 is at October 31. So aiming for
2.7/2.8 seems more realistic.

Pim.

Yes it is mandatory to have a 2.4.x kernel.  Preferably 2.4.19.

Not without more info.

Do you have a core file?  Run gdb on it a get me tha back trace.
Did you try enabling tracing? Turn it on and set me the output.
Did you try getting the lasted ldp-portable from CVS?  I fixed a couple
  or crashes recently.

Here is the config I work with:

[mpls-linux-general] mplsd crash

Hi   Jim ,

  I have two linux boxes running latest ldp-portable with 2.4.18 kernel.

 When I enable "mpls ldp" one interface of one machine  after I have =
enabled the connecting interface of the other , the mplsd will show =
"session delete" , and mplsd crash in both machine .

Could you tell me what's the problem in it ?

I have considered it.  I even talked with the folks on netdev at one point.
At that time I knew I would have problems getting them to accept my changes
to the IPv4 code.  Since that time I have re-written the IPv4 -> MPLS
layer.  Mybe it's time to resume a conversation with the netdev folks.

The main question is how stable mpls-linux-1.1xx?  I can think of one more
"feature" that needs to be implemented before I will try and get netdev
to integrate this: admining down an interface needs to remove all of the
outgoing labels from thet interface, thus releasing all references to that
interface.  Anything else?

Have you considered attempting to get your MPLS support into the kernel

Have you contacted David Miller or Alexy about it ???

Do you have any thoughts about getting it integrated into the kernel ,
and if so, what are they ???

I think i would be good to eventually have full support for MPLS in the

[mpls-linux-general] Problem in compiling mpls-linux1.1

[net g. <net...@ho...>]

Hi Jim and All,

I am using linux 7.3 with kernel 2.4.18 and 2.4.18-3

To apply patch i used command given in QUICK.START

-patch Linux kernel for MPLS for Linux

        patch -p1 < ../mpls-linux-1.1xx/patches/2.4.x-1.1yy.diff

but i didn't find any file with 2.4.x-1.1yy.diff in patch directory but it  
is present in kernel directory.

( What yy stands in "2.4.x-1.1yy.diff ")

finaly i give command on m/c running 2.4.18-3 kernel

[root@sagar linux]# patch -p1< 
../mpls-linux-1.1/patches/kernel/2.4.18-1.130.dif

I get following error --->

There is a now comand line format for mplsadm2 ... although I guess I for=
got
to update the usage output in mplsadm2 :-)

Here is how to do the equivelant of mplsadm -AO gen:1234:eth1:ipv4:192.16=
8.30.2

~-> /mpls/mplsadm2 -A -O 0
Key: 0x0000000e
Out Segment add: Success
~-> /mpls/mplsadm2 -O 0xe -o push:gen:1234:set:eth1:ipv4:192.168.30.2
Out Instr: Success

I'll make sure to update the usage output.

[mpls-linux-general] problem adding out labels

[<br...@ya...>]

Hi James,

I just upgraded my machines to MPLS version 1.152, and
found the 
following problem when adding out labels: 
I am using kernel 2.4.18 with the patch
2.4.18-1.152.diff applied 

[root@nirvana utils]# ./mplsadm2 -dAO
gen:1234:eth1:ipv4:192.168.30.2 
Debug: Success 
Key: 0x00000002 
Out Segment add: Illegal seek 
[root@nirvana utils]# cat /proc/net/mpls_out 
0x00000002 0/0/0 1 

[root@nirvana utils]# ./mplsadm2 -dAO gen:1235:eth1 
Debug: Success 
Key: 0x00000003 
Out Segment add: Illegal seek 
[root@nirvana utils]# cat /proc/net/mpls_out 
0x00000002 0/0/0 1 
0x00000003 0/0/0 1

[mpls-linux-general] MPLS TCP/ICMP problems?

[Luca Da C. <luc...@ti...>]

James, all 

while I was testing mpls linux I found the following "strange" behaviour
while pinging or generating UDP-TCP/IP traffic. My testbed is in this
case was very simple: 

two linux box: 

linux box 1
eth1      Link encap:Ethernet  HWaddr FE:FD:C0:A8:00:01  
          inet addr:192.168.0.1  Bcast:192.168.0.255  Mask:255.255.255.0

[root@mandrake82 root]# cat /proc/net/mpls_*
0x40032400 0/0/0 gen 201 0 1 POP PEEK 
eth0	0	7
0x00000002 120/8950/0 5 PUSH(gen 200) SET(eth1,192.168.0.2) 
[root@mandrake82 root]# /mnt/host/usr/src/iproute2/ip/ip route
192.168.0.2 via 192.168.0.1 dev eth1 lsp 0x2 
10.0.0.0/8 dev eth0  proto kernel  scope link  src 10.192.141.250 
[root@mandrake82 root]# 

linux box 2

[root@mandrake82 root]# ifconfig   
eth0      Link encap:Ethernet  HWaddr FE:FD:C0:A8:00:02  
          inet addr:192.168.0.2  Bcast:192.168.0.255  Mask:255.255.255.0

[root@mandrake82 root]# cat /proc/net/mpls_*
0x40032000 84/6262/0 gen 200 0 1 POP PEEK 
eth0	0	6
[root@mandrake82 root]# 

[root@mandrake82 root]# /mnt/host/usr/src/iproute2/ip/ip route
192.168.0.1 via 192.168.0.2 dev eth0 lsp 0x4   <---------- or different
lsp, doent matter


I dont remember if this problem was already raised by Oliver. With this
configuration (in the second box there is no PUSH opcode, while in the
first one there is corresponding POP) if I ping 198.168.0.2, or I
generate TCP/UDP traffic things works fine and no packets are discarded
as I could expect. I took a tracedump of eth1 and I could see that
outgoing packet have MPLS shim, while ingoing one no (in the situation
ping 192.168.0.2). As attachment I put the result. 

James, is anyone working on this issue? 

Thanks 
Luca

Try not setting the label space (it defaults to 0)

[mpls-linux-general] LDP init

[<yu...@so...>]

Hi Jim, 

I got a few errors from mplsd when I tried LDP between 2 Linux boxes. Is 
this a problem of my LDP configuration or something else? 

I'm using the newest CVS version zebra-ldp and mpls-linux-1.1 on a 
linux-2.4.18 kernel. 

Thanks,
Yuekang

There was a question about this a couple weeks back, you can search the

[mpls-linux-general] module loading problem

[Charles C. <cha...@ho...>]

Hi Jame,

I am still using Redhat 7.3 with kernel 2.4.18.3. I can got it compiled now, 
after I have done the fix you recommended. However, when I try make install, 
make install_modules, there is an error message called : unresolved symbol: 
file ipt_MPLS.o which is stored in 
lib/modules/2.4.18.3cutsom/kernel/net/ipv4/netfilter.
the unknown symbol is mpls_set_nexthop

Thank you for your attention.

Charles

[mpls-linux-general] New zebra-ldp patch

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

If you play with ldp-portable and zebra-ldp you will want to grab the
latest version of ldp-portable via CVS.

This current version fixes some bugs and implements ingress and egress
LER kernel programming.  It also add the abilty for BGP routes to
use LDP routes as part of the recursive lookup, thus mapping BGP routes
to LDP created LSPs.

Re: [mpls-linux-general] mpls on synchronous links

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

The short answer is that I don't know.

The long answer is:
-does syncppp require you to run pppd?  If so, my guess is that it will
 be supported.
-if syncppp doesn not run pppd, then what does the PPP negotiation?
 If it is some other userland app, or the kernel, then there is some more
 work that is needed before it will work.

Re: [mpls-linux-general] MPLS 1.152 patch compilation error

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

I've updated my tree to include the file.

You have two options if you don't want to wait for the next patch:

1. add the line:

#include <linux/if_arp.h>

at the top of the file after the comment

- or -

2. don't configure ATM and FR support in your kernel.

Thanks,
Jim
