8e66a0ebb9 Hopefully finished kernel syncer (krt) rewrite:
o  Interface syncing is now a part of krt and it can have configurable
     parameters. Actually, the only one is scan rate now :)
  o  Kernel routing table syncing is now synchronized with interface
     syncing (we need the most recent version of the interface list
     to prevent lots of routes to non-existent destinations from
     appearing). Instead of its own timer, we just check if it's
     route scan time after each iface list scan.
  o  Syncing of device routes implemented.
  o  CONFIG_AUTO_ROUTES should control syncing of automatic device routes.
  o  Rewrote krt_remove_route() to really remove routes :)
  o  Better diagnostics.
  o  Fixed a couple of bugs.

f39e4713c2 Rewritten kernel syncer. Now uses the rta trickery I've introduced yesterday
and does things "the right way". Few things are still missing (device
routes etc.), I'll add them later in the evening.

12df4d909b KRF_* flags moved to krt.h as they are internal to kernel syncer,
fib->pad0,pad1 renamed to x0,x1 and in case of struct net x0 is reserved
for kernel syncing as well.

980ffedbb0 Kernel syncer is now configurable. It will probably need some more
options, but at least basic tuning is possible now.

c74c0e3cdf First attempt at protocol configuration (now done only for RIP). 1998-11-27 21:09:57 +00:00

7d83290780 Generate router_id automatically if possible (standard "smallest of local
regular interface addresses" rule).

Protocols should NOT rely on router_id existence -- when router ID is not
available, the router_id variable is set to zero and protocols requiring
valid router ID should just refuse to start, reporting such error to the log.

0804525255 Basic kernel routing table syncing implemented. Learning of routes installed
by other programs or the kernel itself is not supported yet, but it's not
needed for development of other protocols.

567e6c6220 Use (SOCK_DGRAM,IPPROTO_IP) socket instead of (SOCK_STREAM,IPPROTO_TCP).
This is exactly what Linux ifconfig does and seems to be the preferred way.

4cf45766ba Exporting fill_in_sockaddr() for use by other unix-dependent code. 1998-10-19 17:47:50 +00:00

7e7790c61f Since almost every UNIX system requires different techniques for reading
the kernel routing table as opposed to modifying it which is approximately
the same on non-netlink systems, I've split the kernel routing table
routines to read and write parts. To be implemented later ;-)

0432c0173b Split protocol init to building of protocol list and real protocol init.
Added kernel route table syncer skeleton.

47b793064c Solve chicken-and-egg problems with protocol startup. We now queue all inactive
protocols and don't send route/interface updates to them and when they come up,
we resend the whole route/interface tables privately.

Removed the "scan interface list after protocol start" work-around.

93f1c532e9 Moved scanning of interfaces, so that they get initialized after all
routing protocol instances.

c93214d442 o There are cases when SIOCGIFINDEX is defined, but it doesn't work. When
this happens, don't reject the whole interface, just mark it as index 0.
o  Removed Pavel's comment about EFAULT and SIGSEGV. EFAULT is a valid return
   code for cases where the buffer is too small.
o  Commented out the smart interface list size logic temporarily as it seems
   Linux 2.0 SIOCGIFCONF doesn't react to ifc_req==NULL sanely. Replaced it
   by exponential stepping.

fdf33cde1c Strange, on atrey ioctl() does not fill structure, and bird segfaults
on it. Now we "only" die().

9556f22585 debug() and log() use the new printf. Feel free to use new formatting
sequences for all output.

More to come later...

af847acc27 Whee, multicast sockets work!
Implemented recurrent timers.

8a48ecb8b1 Implemented scanning of network interfaces. Mostly very ugly code due to
terrible kernel interface (SIOGIFCONF and friends).

b5d9ee5c87 Added UNIX implementation of both timers and sockets. Timers should work,
sockets were tested only in TCP mode. main.c now contains some test
cases for socket code.

a2ccbb0b97 Implemented timers. Using bird_clock_t for absolute time from now... 1998-05-24 14:40:29 +00:00

25697773b5 The library is now glued together from generic and OS-dependent parts
by the `mergedirs' script. Few more IP address manipulation functions
and some fixes.

6032aa6ade Added new subdir for UNIX-dependent files.
Now contains only functions for logging, but it will change soon.
