2018-05-03	Babel: Fix type of route entry router ID	Ondrej Zajicek (work)
	The router ID being assigned to routes was a uint, which discards the upper 32 bits. This also has the nice side effect of echoing the wrong router ID back to other routers. Thanks to Toke Hoiland-Jorgensen for the patch.
2018-02-13	Babel: Fix accidental bitwise or assignment	Ondrej Zajicek (work)
	Fix an accidental bitwise or assignment that was supposed to be a comparison. Thanks to Toke Hoiland-Jorgensen for the patch.
2018-02-13	Babel: Add source-specific routing support	Ondrej Zajicek (work)
	This patch adds support for source-specific routing to the Babel protocol. It changes the protocol to support both NET_IP6 and NET_IP6_SADR channels for IPv6 addresses. If only a NET_IP6 channel is configured, source-specific updates are ignored. Otherwise, non-source-specific routes are simply treated as source-specific routes with SADR prefix 0. Thanks to Toke Hoiland-Jorgensen for the original patch. Minor changes by Ondrej Santiago Zajicek.
2017-12-07	Timers: Revert temporary names and remove old timer.h	Ondrej Zajicek (work)

2017-12-07	Babel: More changes and bugfixes	Ondrej Zajicek (work)
	Several changes and bugfixes in Babel, namely: - Exported route parameters stored directly in route table entry - Exported non-babel routes no longer stored in per-entry route list - Route update, selection and retraction simplified and fixed - Route feasibility is evalualated per update and stored with route - Unreachable route handling fixed, based on hold interval - Added 'show babel routes' command Overall, it fixes some issues with proper propagation of triggered updates, making Babel convergence after topology change almost instant.
2017-12-07	Babel: Fix handling of seqno requests	Ondrej Zajicek (work)
	Old behavior has several deficiencies compared to standard behavior (no triggered updates for replies, no retransmissions, ...).
2017-12-07	Babel: Remove babel_proto ptr from babel_entry	Ondrej Zajicek (work)

2017-12-07	Babel: Fix hello timeout for short hello intervals	Ondrej Zajicek (work)

2017-12-07	Babel: Revamp cost computation and run route selection when cost change	Ondrej Zajicek (work)
	Also fix several minor bugs and add 'limit' option for k-out-of-j link sensing strategy. Change default from 8-of-16 to 12-of-16. Change IHU expiry factor from 1.5 to 3.5 (as in RFC 6126).
2017-12-07	Babel: Fix unicast seqno requests	Ondrej Zajicek (work)

2017-12-07	Babel: Avoid batch seqno updates	Ondrej Zajicek (work)

2017-12-07	Babel: Fix Hello and IHU expiration	Ondrej Zajicek (work)

2017-12-07	Babel: Update to new timers	Ondrej Zajicek (work)

2017-12-07	Timers: Replace old timers with microsecond timers	Ondrej Zajicek (work)
	The old timer interface is still kept, but implemented by new timers. The plan is to switch from the old inteface to the new interface, then clean it up.
2017-12-07	Nest: Maintain separate IPv4, IPv6 and LLv6 preferred addresses	Ondrej Zajicek (work)
	Also redesign preferred address selection and update protocols to use appropriate preferred address. Based on a previous work by Jan Maria Matejka.
2017-10-17	Babel: Interface address irrelevant for interface pattern matching.	Jan Maria Matejka

2017-06-08	Babel: Add support for dual-stack IPv4/IPv6 operation	Ondrej Zajicek (work)
	This adds support for dual-stack v4/v6 operation to the Babel protocol. Routing messages will be exchanged over IPv6, but IPv4 routes can be carried in the messages being exchanged. This matches how the reference Babel implementation (babeld) works. The nexthop address for v4 can be configured per interface, and will default to the first available IPv4 address on the given interface. For symmetry, a configuration option to configure the IPv6 nexthop address is also added. Thanks to Toke Høiland-Jørgensen <toke@toke.dk> for the patch.
2017-02-22	Babel post-merge fixes	Jan Moskyto Matejka

2016-12-10	Babel: Update to integrated branch	Ondrej Zajicek (work)

2016-11-01	Build: switch on -Wextra, get rid of most of the warnings	Jan Moskyto Matejka
	There are several unresolved -Wmissing-field-initializers on older versions of GCC than 5.1, all of them false positive.
2016-07-20	Babel: Immediately update hello interval on interface reconfigure	Ondrej Zajicek (work)
	An interface reconfiguration may change both the hello and update intervals. An update interval change is immediately put into effect, while a hello interval change is not. This also updates the hello interval immediately (if the new interval is shorter than the old one), and sends a hello to notify peers of the change.

2016-07-19	Babel: Do not maintain feasibility distance for our own routes	Ondrej Zajicek (work)
	We do not need to maintain feasibility distances for our own router ID (we ignore the updates anyway). Not doing so makes the routes be garbage collected sooner when export filters change. Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk>
2016-07-19	Babel: Do not keep an infeasible route as selected	Ondrej Zajicek (work)
	When a route becomes infeasible it should not be kept as selected; this is forbidden by section 3.6 of the RFC and prevents subsequent updates from the same router ID from replacing it. Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk>
2016-07-19	Babel: Send wildcard retractions on shutdown and startup	Ondrej Zajicek (work)
	This makes BIRD send a wildcard retraction on all interfaces before shutting down and right after starting up. This helps ensure that neighbours will discard the announced routes as soon as possible, rather than only after the normal timeout procedures. Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk>
2016-07-19	Babel: Rework handling of retractions	Ondrej Zajicek (work)
	An update with wildcard AE and infinite metric should be treated as a global retraction of all prefixes announced by that neighbour, per section 4.4.9 of the RFC. In addition, router ID and seqno in retraction updates should be ignored. This reworks the handling of retractions and adjusts the parser to handle all this correctly.

2016-04-28	Add the Babel routing protocol (RFC 6126)	Ondrej Zajicek (work)
	This patch implements the IPv6 subset of the Babel routing protocol. Based on the patch from Toke Hoiland-Jorgensen, with some heavy modifications and bugfixes. Thanks to Toke Hoiland-Jorgensen for the original patch.
