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

70591fa064 Compile and use the new configuration code by default. 1998-11-27 19:37:07 +00:00

9158ca99f7 Complain loudly if the logging buffer would overflow. 1998-11-16 21:41:21 +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.
 1998-10-17 11:05:18 +00:00
Martin Mares
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().

c25e90efed Added comment explaining `now'. 1998-07-15 19:42:23 +00:00

86b0023033 Making SIGUSR1 dump also all protocols. 1998-07-09 19:37:39 +00:00

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

5331da6a4d Fixed processing of timers. 1998-06-04 20:27:49 +00:00

fd50083df4 Killed socket debug code. Initialize config pool and protocols. 
More to come later...

869c695998 Synced to new interface code. 1998-06-01 21:41:32 +00:00

af847acc27 Whee, multicast sockets work! 
Implemented recurrent timers.
 1998-05-26 21:46:38 +00:00
Martin Mares
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.
 1998-05-24 14:50:18 +00:00
Martin Mares
a2ccbb0b97 Implemented timers. Using bird_clock_t for absolute time from now... 1998-05-24 14:40:29 +00:00
Martin Mares
2326b001d6 Added routing table and routing attribute code. 1998-05-20 11:54:33 +00:00
Martin Mares
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.
