Hello,
I had git-cloned the net-2.6.25.git tree today;
Then I ran "make menuconfig" and accepted the defaults without any change.
I want to build this tree with network namespace support.
I saw that in 2.6.25/net/core/net_namespace.c
we have some #ifdef CONFIG_NET_NS ; I did not CONFIG_NET_NS in "make
menuconfig".
So I added in net_namespace.c #define CONFIG_NET_NS, before the first
#ifdef CONFIG_NET_NS; then I ran make.
I saw the following warning:
WARNING: vmlinux.o(.text+0x1d47cd): Section mismatch: reference to .init.text:
(between 'copy_net_ns' and 'net_enable_timestamp')
Is there something wrong here causing this "Section mismatch"?
or did I do something wrong?
Regards,
Andy

Hi Andy,
If you want to activate the network namespace, you should disable the
sysfs. This is a temporary restriction until Greg-KH integrates the
sysfs per namespace:
https://lists.linux-foundation.org/pipermail/containers/2007-December/009347.html
Can you try to using the menuconfig to enable the network namespace and
check if you still have the section mismatch ?
General setup
-> Prompt for development and/or incomplete code/drivers => enable
-> Configure standard kernel features => enable
File systems
-> Pseudo filesystems
-> sysfs file system support => disable
Networking
-> Networking options
-> Network namespace support => enable
Thanks
