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
multicast abilities depending on definedness of symbols and use hard-wired
system-dependent configuration defines instead.
Please test whereever you can.
The changes are just too extensive for lazy me to list them
there, but see the comment at the top of sysdep/unix/krt.c.
The code got a bit more ifdeffy than I'd like, though.
Also fixed a bunch of FIXME's and added a couple of others. :)
documented the remaining ones (sysdep/cf/README).
Available configurations:
o linux-20: Old Linux interface via /proc/net/route (selected by default
on pre-2.1 kernels).
o linux-21: Old Linux interface, but device routes handled by the
kernel (selected by default for 2.1 and newer kernels).
o linux-22: Linux with Netlink (I play with it a lot yet, so it isn't
a default).
o linux-ipv6: Prototype config for IPv6 on Linux. Not functional yet.
