Subject: Re: How is IPv6 dhcp supposed to work?
Date: Wed, 18 Jun 2014 07:49:38 -0700 [thread overview]
Message-ID: <53A1A702.1020300@candelatech.com> (raw)
In-Reply-To: <1403098990.2266.13.camel@dcbw.local>
After more printk debugging, it seems it is failing to accept the RA due to
ipv6_chk_addr failing in the ndisc_router_discovery method.
This is probably because one interface on my system is running radvd
(on one side of a veth pair), and the peer veth is supposed to be
accepting the ra.
The chk_addr is checking if the source addr for the RA is not found locally, as far
as I can tell, but in my case, it is local, and it still should be accepted.
My case is a bit special (I'm doing virtual network type things), but
maybe there is a more useful reason to allow this restriction to be
relaxed with yet another sysctl?
Thanks,
Ben
