IPv6 address change - Kernel Segfault
Hello,
I use debian lenny and when I do these steps kernel always segfault.
1. configure your /etc/network/interfaces
add inet6 adres with /52 netmask and restart networking
2. change your /etc/network/interfaces
change mask to 64
3. restart networking and check IPv6 address - It has always /52
4. so ip del addr .... dev eth0
5. ip add addr .../64 dev eth0
Now kernel segfault.
It doesn't happend when you use only ip or ifconfig commands, only
with debian networking scripts.
Kernel: Linux dns1 2.6.34 #1 SMP Thu Jul 22 10:36:05 CEST 2010 x86_64 GNU/Linux
Segfault log in attachement.
