0cf86f0fc3 Renamed DEBUG' symbol to DEBUGGING' to prevent collisions with token

0b62c3a7c7 Trivial 15-line bison excercise: Implemented expressions including
user-defined numeric symbols. Whenever possible, use `expr' instead
of `NUM' to get full express ion power :-)

b4712244a0 Dummy grammar for RIP configuration. Now empty, but must be here since

9158ca99f7 Complain loudly if the logging buffer would overflow. 1998-11-16 21:41:21 +00:00
Martin Mares
53a416d376 Implemented snprintf and similar functions. It took a lot of thinking,
but the modifications were relatively simple and straightforward.

c3e9b2ab24 RIP now includes notion of interface, and is correctly talking to
itself on second host. Split horizont is broken.

db6984c43c rte_update: Doesn't loop forever when multiple routes point to the same
destination.

dc7c7494e3 RIP _NOW_ actually talks to itself (workaround core bug: send data
from other port than we receive at), few FIXME's added.

756b86dea3 Learn static device routes from the kernel (temporary until we can make
such things configurable).

acc62f5e1d Insert/remove hooks return void, not int. 1998-10-20 15:17:38 +00:00

a0762910a6 Added pointer to network to RTE. The complications with passing NET separately
aren't worth 4 bytes per RTE.

rte_discard and rte_dump don't need net * as parameter.

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.

16a8ba30a9 We parse /proc/net/route and flag RT entries according to it. More to come
today in the morning...

4c45595e3b o FIB flags now available for FIB users.
o  struct network: FIB flags used for kernel syncing.
o  struct network: `next' field deleted (historical relic).

ab3a76a382 Added ipa_from_u32 and ipa_from_u32 for use in the kernel sync code (IPv4 only).
Don't ever think of using it in routing protocols.

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 ;-)

5b22683d2f After contemplating about RIP route timeouts for a long time, I've implemented
protocol callbacks for route insertion and deletion from the central table.
RIP should maintain its own per-protocol queue of existing routes, scan it
periodically and call rte_discard() for routes that have timed out.
