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

[steve at snewbury.org.uk]

The low broadcast frequency on 2.6.29 is explianed by the lack of a specified interval, I left it running for quite a while on 2.6.31, but the only broadcasts were from startup and shutdown of radvd.

Just to make clear, solicted unicast is working fine on either kernel.

I'll try using HUP after the tunnel device comes up, I suspect it will work. 

Sorry about not replying in-line, this mail agent is pretty limited. :(

I note that you don't have {Min,Max}RtrAdvInterval configured.  It will take at least this long (the default value) for radvd to detect 
the link has come back up, and possibly the next cycle before it's 
done reactivating the interface.  Make sure that this is not skewing 
your test results.

Could you run a debug output with only one interface configured and 
above in mind?

By restarting radvd, do you mean a complete restart or sending HUP 
signal?  The latter should be enough but the code paths are different.
