When an interface goes down, (Linux) kernel removes routes pointing to
that ifacem but does not send withdraws for them. We rescan the
kernel table to ensure synchronization.
Thanks to Alexander Demenshin for the bugreport.

Although RFC 3542 allows both cases, Theo de Raadt thinks
he knows better, and msg_controllen without last padding
fails on OpenBSD.
Thanks to Job Snijders for the bugreport.

Thanks to Frederik Kriewitz for the patch.

Also significant core protocol state changes needed for that,
global graceful restart recovery state and kernel proto support
for recovery.

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

RIP sockets for multiple ifaces collided, because we cannot bind to
a specific iface on BSD. Workarounded by SO_REUSEPORT.
Thanks to Eugene M. Zheganin for the bugreport.

Supports OSPF and BGP and also statically configured sessions.

Thanks to Sergey Popovich for the patch.

Thanks to Thierry Fournier for the original patch.

Now it compiles and mostly works.
|
|
The bug caused that krt_prefsrc attribute was not processed when a route
received from a kernel protocol was exported to another kernel protocol.
Thanks to Sergey Popovich for a bugreport.

Implemented eval command can be used to evaluate expressions.
The patch also documents echo command and allows to use log classes
instead of integer as a mask for echo.

Thanks to Fritz Grimpen for the patch.

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.
|
|
Several new configure command variants:
configure undo - undo last reconfiguration
configure timeout - configure with scheduled undo if not confirmed in timeout
configure confirm - confirm last configuration
configure check - just parse and validate config file
|
|
When 'import keep rejected' protocol option is activated, routes
rejected by the import filter are kept in the routing table, but they
are hidden and not propagated to other protocols. It is possible to
examine them using 'show route rejected'.
|

|
Allows to send and receive multiple routes for one network by one BGP
session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.
|
|
|
|
Also fixes some minor bugs in include.
Thanks Kelly Cochran for suggestion and draft patch.

Just one more renaming, old krt_set_notify() to krt_replace_rte().
|
|
Remove support for historic Linux kernels,
merge krt-iface, krt-set and krt-scan stub headers.
|
|
OS-dependent functions renamed to be more consistent,
prepared to merge krt-set and krt-scan headers.
Name changes:
struct krt_if_params -> struct kif_params
struct krt_if_status -> struct kif_status
struct krt_set/scan_params -> struct krt_params
struct krt_set/scan_status -> struct krt_status
krt_if_params_same -> kif_sys_reconfigure
krt_if_copy_params -> kif_sys_copy_config
krt_set/scan_params_same -> krt_sys_reconfigure
krt_set/scan_copy_params -> krt_sys_copy_config
krt_if_scan -> kif_do_scan
krt_set_notify -> krt_do_notify
krt_scan_fire -> krt_do_scan
krt_if_ -> kif_sys_
krt_scan_ -> krt_sys_
krt_set_ -> krt_sys_
