[mpls-linux-general] mpls-linux 1.959

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

I've released mpls-linux 1.959.  The main change is a fix for netfilter so
that NHLFEs get released when the netfilter rule that referenced it goes aw=
ay.
(thanks to Tom Kleiberg <t.k...@gm...> for pointing me at the bug)

At this time I build RPMs for Fedora 8 and 7 and Fedora Core 6.  All of whi=
ch
can be reached via my yum repo:

    http://mpls-linux.sourceforge.net/fedora/mpls-linux.repo

I'll be posting 1.959 to the file section of SF, but that is a slow
and painful process. Until that is in place you can access the contents
of the yum repo directly by going here:

Re: [mpls-linux-general] cannot remove iptables rule with mpls target / cannot remove nhlfe key used by iptables.

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

Just wanted to confirm that I'm seeing this issue on mpls-linux 1.958
on FC6 (and F7 and F8).

I will dig into it.

Re: [mpls-linux-general] cannot remove iptables rule with mpls target / cannot remove nhlfe key used by iptables.

[Tom K. <t.k...@gm...>]

Hello James,

Thanks for your time. I'm using the pre-built rpms for FC6 (on FC6)  
version 1.958 that are available on SourceForge, i.e. the  
kernel,iptables etc.  I have tried several ways to workaround the  
problem and so far no success. Flushing the chain will not work. Using  
a custom chain, and flushing and deleting that afterwards also will  
not work.

Kind regards,

Tom

Completely different problem.  In those posts they couldn't even create ipt=
ables
rules.  It was due to a change in kernel structures for netfilter targets.
This is the first I'm hearing of your issue.

Can you please provide details about the MPLS version, iptables version, an=
d linux
distribution you are using.

What happens if you do a iptables -F instead of trying to remove
just the single rule?

[mpls-linux-general] cannot remove iptables rule with mpls target / cannot remove nhlfe key used by iptables.

[Tom K. <t.k...@gm...>]

Hello,

I came across a problem with removing an mpls target from iptables.
Apparently, the problem was found previously and posted on the mailing list:
http://sourceforge.net/mailarchive/message.php?msg_id=58990.192.168.1.72.1177109560.squirrel%40webmail.larces.uece.br
http://sourceforge.net/mailarchive/message.php?msg_id=1801039839.20070421093542%40s2001.tu-chemnitz.de
http://sourceforge.net/mailarchive/message.php?msg_id=4631EBCD.8090708%40gmail.com

The target can be removed from iptables only by using the rule number
instead of the complete rule description.

Unfortunately, I encountered another issue, which could be related to this
one. Namely, when a nhfle key has been used by an iptables target and the
iptables rule is later removed,
then the key can no longer be removed from the nhlfe table. The key can now
only be removed from the nhlfe table by
rebooting the pc.

The following commands will show the error.
mpls nhlfe add key 0
iptables -t mangle -A OUTPUT <some rule> -j mpls --nhlfe <key>
iptables -t mangle -D OUTPUT <#some rule>
mpls nhlfe del key <key>

The last command will report the error:
RTNETLINK answers: Device or resource busy


dmesg reports:
MPLS DEBUG net/mpls/mpls_nhlfe.c:468:mpls_del_out_label: enter
MPLS DEBUG net/mpls/mpls_nhlfe.c:492:mpls_del_out_label: Node 4 is being
used
MPLS DEBUG net/mpls/mpls_nhlfe.c:493:mpls_del_out_label: exit
MPLS DEBUG net/mpls/mpls_netlink.c:346:genl_mpls_nhlfe_del: Exit: -16

Can anyone confirm this problem and is there a solution/workaround?

Kind regards,

Tom

Their are a couple of implementation.  I start the work to integrate one
of them, but that work has not been finished.  The code is in my development
tree.  See http://mpls-linux.sf.net/ for details about how to access my
development tree.

If you choose to try and do some development on it, please join the
mpls-linux-devel mailing list, and let me know about your work.  I can
help bring you up to speed.

ds2exp cannot end a NHLFE.  The EXP must be set before you do the PUSH.

The problem seems to be the way the kernel handles /32 address in a 
routing table.  Namely it doesnt.  That is I fixed the dummy0 interface 
routing problem by simply assigning it a /30 bit mask, aka a network 
address.

ifcfg-dummy0 = /30 bit mask
LER_1(dummy0)<------------->(dummy0)LER_2

Just an FYI on Explicit null label testing this morning, sorry if this 
is old hat for anyone. 

I was having a problem getting it to work even though the "mpls ilm 
show" was stating the correct pop was configured, incoming packets 
appeared not to be routed via kernel after the pop.  It turns out there 
is an issue with targeting the "dummy0" interface.  Once I changed to a 
real ethX interface owned by the target router the expected action 
occurred, that is, pinging  from one  linux router where labels are

Re: [mpls-linux-general] why there are no patches for 1.958?

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

Its all about time, being that I'm the only one working on this
project I have to do what I can in the shortest amount of time.
It takes more time to build a mpls-linux tar ball, and it takes more
time to support users who want to build their own binaries.

Plus if you really wanted you could:
- extract the SRPMs (there are RPM tools for almost all distributions)
- use p4 to pull a development tree

If someone wants to step up and start helping with release managment
I'd be more then happy to start producing tar balls again.

[mpls-linux-general] why there are no patches for 1.958?

[Wojtek D. <wd...@ya...>]

Could anybody provide patches for mpls-linux-1.958
just like it was in mpls-linux-1.955.tar.gz?

I want to install 1.958 version on ubuntu just like I
did with 1.955 and I need only patches. Fedora's RPMs
does not work (no surprise).

Re: [mpls-linux-general] Vote Ron Paul 2008! XStftQ

[Chris R. <Chr...@nr...>]

Anyone looked into how to make MPLS-Linux support "IPv4 Explicit NULL 
Label".  That is having a LER pop all the labels and then route based on 
the IP header.  The requirement is to have a dummy0 interface be the 
source/destination within the LER, ergo a ping packet between the 
connect LERs dummy0 interfaces would be labeled.  I can get the labels 
inserted on the outgoing packets but can't seem the find the correct 
configuration to have all the labels popped at the destination LER.

Typcial configuration is:

Host(ping)<-->LER<------(ping with label)----->LER<---->(ping)Host

Desired configuration:

LER(dummy0)(ping with label)<----------->ping with label)(dummy0)LER

Any idea....thanks
....Chris

Re: [mpls-linux-general] Is ldp working?

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

I believe the general consenus is that quagga-mpls on a 1.958 kernel
does not work.

[mpls-linux-general] Is ldp working?

[Javier L. <jml...@gm...>]

Hello,

I'm a university student and I'm doing my final project. I would want to
know if ldp is working, and if it is, which is the latest version. I have
tried statics routes and it works well, but I'm having some problems with
ldp.

Thank you.

There is only one developer on this project and the vrf-linux project, me.
At this time my focus is on vrf-linux, trying to bring it upto date.

If you would like to assist with the development, please join the
mpls-linux-devel mailing list and I'll be happy to answer questions
about howto start contributing.

[mpls-linux-general] quagga with ldpd

[<dad...@gm...>]

Because the version of ldpd now can't work well on mpls-linux-1.958,
it has some problems when operating.

May I ask that what time the new quagga with ldpd will be released?
Do developers have schedule?

Best regard.
