2017-02-09npd: rework IPv6 relay logic (FS#396)Hans Dedecker
Rework the IPv6 relay logic to make it more robust by making use of libnltiny to process netlink messages. At the same time reimplement the IPv6 relay finite state machine to make the relay logic less error prone Signed-off-by: Hans Dedecker <dedeckeh@gmail.com>

2016-12-27router: skip parse_routes when ra_default > 1Stijn Tintel
It does not make sense to scan the entire routing table if the decision will be overridden afterwards. This makes it possible to use odhcpd on a router with full IPv6 BGP table, by setting ra_default to 2. Without this change, odhcpd is constantly busy reading /proc/net/ipv6_route, and doesn't respond to router solicitations in time. Signed-off-by: Stijn Tintel <stijn@linux-ipv6.be>

2015-10-20Don't overflow router lifetimeWill Mortensen
When a prefix lifetime was greater than UINT16_MAX, we would advertise a shorter router lifetime (even potentially 0). Saturate instead.

2014-10-30Fix IPv6 DNS server adddress selectionHans Dedecker
Fix selection of IPv6 DNS address in DHCPv6 and RA overwrite as an address could be selected with preferred lifetime zero while IPv6 addresses are in use with non zero preferred lifetimes. Fix tries to pick the IPv6 address with the longest preferred lifetime now. Fixes also the issue an IPv6 address with preferred lifetime zero could be returned in DHCPv6 DNS server option while an IPv6 address with non zero preferred lifetime is returned as DNS recursive RA option for the same set of available IPv6 addresses.
