Re: [mpls-linux-devel] Kernel 2.6.32.11 or better

[Renato W. <ren...@gm...>]

Hi,

I have already ported mpls-1.963 to the kernel 2.6.32.11, I just didn't
ported the ebtables module.

The only problem is that you should disable the stack protector on the
kernel,
since a buffer overflow occurs when you bind a route with a nhlfe key.
I'm working on this bug, but disabling stack protector everything should
work.

Patch for kernel 2.6.32.11:

1 - Get kernel 2.6.32.11:
http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.32.11.tar.bz2

2 - Apply attached patch: patch -p1 < ../linux-2.6.32.11-mpls1.963.patch

3 - make menuconfig:

Networking options  --->
<*>   Multiprotocol Label Switching
<*>   MPLS: Virtual tunnel interface
<*>   IP: MPLS support
<*>   The IPv6 protocol  --->
    <*>   IPv6: MPLS support

[*] Network packet filtering framework (Netfilter)  --->
     Core Netfilter Configuration  --->
<*>   "mpls" target support

General setup  --->
[*]   Network namespace

Disable stack protector

Processor type and features  --->
[ ] Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)

4 - build kernel...


Patch for iproute2:

1 - Get iproute2-2.6.33:
http://devresources.linuxfoundation.org/dev/iproute2/download/iproute2-2.6.33.tar.bz2

2 - Apply attached patch: patch -p1 < ../iproute2-2.6.33-mpls1.963.patch

3 - $ make
     # make install (*)

* build dependencies (debian5): libdb-dev, bison, flex


Patch for iptables:

1 - Get iptables-1.4.7:
http://www.netfilter.org/projects/iptables/files/iptables-1.4.7.tar.bz2

2 - Apply attached patch: patch -p1 < ../iptables-1.4.7-mpls1.963.patch

3 - $ ./configure
    $ make
    # make install


 Greetings from Brazil,
 Renato.
