I left my box to run some test scripts last night with net-next tree where patch
IPv6: Removing unnecessary NULL checks was applied. Crash had occurred when script
executed "ip route change xxx/128 dev eth0" with non existing target twice
in a row. (non existing target == there was no previous route to be changed)
This was not occuring with kernel where only
IPv6 routing, NLM_F_* flag support: REPLACE and EXCL flags support, warn about missing CREATE flag
and
IPv6 routing, NLM_F_* flag support: warn if new route is created without NLM_F_CREATE
were applied.
Anyways, I cannot think how info struct could be NULL, so I am a bit
puzzled. Looks like I am missing some piece here. Anyways, somewhere in
these patches is lurking a bug. I try to find the reason.
Sorry for the trouble.
