[LARTC] [BUG?] ip ru flush && RTNETLINK answers: Numerical result out of range

[Luciano Ruete]

After an: 
# ip ru flush
I loose all my ip rules but the priority 0 one. 
root at sarasvati:~# ip ru
0:      from all lookup 255
root at sarasvati:~#  

Ok with that, but now i'm not able to insert any new rule.
This leads to a total loose of conectivity.

root at sarasvati:~# ip ru add from all table default
RTNETLINK answers: Numerical result out of range
root at sarasvati:~# ip ru add from all lookup main
RTNETLINK answers: Numerical result out of range

Even seting the priority value by hand, i got the same error:

root at sarasvati:~# ip ru add from all lookup main priority 32766
RTNETLINK answers: Numerical result out of range

To be able to send this e-mail without rebooting i had to insert my gw ip 
routes in table 255.

Is this a bug in iproute?
