[radvd-devel-l] radvd stuck on linux 2.6.31+

[Steven J Newbury]

Having just upgraded my kernel to 2.6.31, I've found radvd now only
sends a RA on startup, then again on exit, the rest of the time is spent
sleeping, apparently waiting on a fd.  It's also not responding to
solicited requests while stuck in this state.

I was previously running with working IPv6 routing on 2.6.29-rc6.

The server is running radvd version 1.5, it was previously running 1.2,
but I upgraded to see if it fixed the problem.

This is from my client (on startup of radvd):
> #

> 	AdvHomeAgentFlag off;
> 	AdvDefaultPreference medium;

> 		AdvRouterAddr on;
> 	}; # End of prefix definition
> 
> 
> 	RDNSS 2a01:xxxx:xxxx:53::1

> 		AdvRDNSSPreference 12;
> 		AdvRDNSSOpen on;
> 		AdvRDNSSLifetime 600;
> 	}; # End of RDNSS definition
>

The only other significant change to my system is enabling 
CONFIG_IP_MULTIPLE_TABLES.
