The old static route was not removed when the nexthop changed and the
new one was not viable (no neighbor).
Thanks to Pierluigi Rolando for the original patch.

I/O:
- BSD: specify src addr on IP sockets by IP_HDRINCL
- BSD: specify src addr on UDP sockets by IP_SENDSRCADDR
- Linux: specify src addr on IP/UDP sockets by IP_PKTINFO
- IPv6: specify src addr on IP/UDP sockets by IPV6_PKTINFO
- Alternative SKF_BIND flag for binding to IP address
- Allows IP/UDP sockets without tx_hook, on these
sockets a packet is discarded when TX queue is full
- Use consistently SOL_ for socket layer values.
OSPF:
- Packet src addr is always explicitly set
- Support for secondary addresses in BSD
- Dynamic RX/TX buffers
- Fixes some minor buffer overruns
- Interface option 'tx length'
- Names for vlink pseudoifaces (vlinkX)
- Vlinks use separate socket for TX
- Vlinks do not use fixed associated iface
- Fixes TTL for direct unicast packets
- Fixes DONTROUTE for OSPF sockets
- Use ifa->ifname instead of ifa->iface->name

Fixes some bugs and uses generic hash implementation.

This is more consistent with common usage and also with the behavior of
other implementations (Cisco, Juniper).
Also changes the default for gw mode to be based solely on
direct/multihop.

Supports OSPF and BGP and also statically configured sessions.

Thanks to Pierre Pfister for the patch.
|

Similar to allowas-in option on other routers.

Thanks to Sergey Popovich for the patch.
|
|
Now it compiles and mostly works.

Neighbor events related to received route next hops got mixed up with
sticky neighbor node for an IP of the BGP peer. If a neighbor for a next
hop disappears, BGP session is shut down.
|
|
|
|
|
|
If TX buffers were full during BGP session shutdown
then a protocol waited indefinitely to be able to
send notification packet to close the session.

Interfaces for OSPF and RIP could be configured to use (and request)
TTL 255 for traffic to direct neighbors.
Thanks to Simon Dickhoven for the original patch for RIPng.
|
|
Implements support for IPv6 traffic class, sets higher priority for OSPF
and RIP outgoing packets by default and allows to configure ToS/DS/TClass
IP header field and the local priority of outgoing packets.
|
|
Also fixes OSPFv3 routing table calculcation w.r.t.
errata 2078 to RFC 5340.

Thanks to Fritz Grimpen for the bugfix.

Thanks to Peter Christensen for the bugfix.

BIRD used zero netmask in hello packets on all PtP links, not just on
unnumbered ones. This patch fixes it and adds option 'ptp netmask'
for overriding the default behavior.
Thanks to Alexander V. Chernikov for the original patch.
|
|
BGP next hop attributes with empty link-local IPv6 addresses were not
handled properly.
Thanks to Sergey Popovich for the bugfix.
|
|
This option allows to keep the received next hop even in cases when
the route is sent to an interface with a different subnet.
|
|
Configured NBMA neighbors in OSPFv3 should be link-local addresses, old
behavior was to silently ignore global ones. The patch allows BIRD to
accept global ones, but adds a warning and a documentation notice.
Thanks to Wilco Baan Hofman for the bugreport.

During reconfiguration, iface routes were installed even when iface was down.
|
|
The RAdv protocol could be configured to change its behavior based on
availability of routes, e.g., do not announce router lifetime when a
default route is not available.
|
|
They have different behavior w.r.t. filtered routes that are kept.
