0bcba21e89 When not debugging, daemonize automatically. 2000-05-08 19:10:36 +00:00

9a220cabbc #ifdef out lots of debugging information.
The long resource/routing table dump printed upon startup is gone now
and if you wish to see it, just send bird SIGUSR1 or use the `debug'
commands.

f75e3bbc01 Fixed a couple of nasty CLI bugs which were triggered on long or multi-part
outputs. It took a whole evening to hunt them down, but now the CLI seems
to work fine.

Now I run three BGP connections with several thousand routes!

e1ddd99377 Changed handling of incoming connections, so that we can send data
from the send hook without worrying about existence of socket buffers.

Also, don't forget to copy peer addresses.

3991d84e8f Changed initialization of protocol list -- now we call proto_build() instead
of calling the protocols manually.

Implemented printing of dynamic attributes in `show route all'.

Each protocol can now register its own attribute class (protocol->attr_class,
set to EAP_xxx) and also a callback for naming and formatting of attributes.
The callback can return one of the following results:

	GA_UNKNOWN	Attribute not recognized.
	GA_NAME		Attribute name recognized and put to the buffer,
			generic code should format the value.
	GA_FULL		Both attribute name and value put to the buffer.

Please update protocols generating dynamic attributes to provide
the attr_class and formatting hook.

221135d6bf Include "lib/string.h" instead of <string.h>. It should give us bzero()
and other non-portable functions on all systems.

320f417357 Defined sk_close() which closes the socket safely even if called from
socket hook. Replaces the SK_DELETED hack.

Squashed a couple of bugs in handling of TCP sockets.

6b9fa32080 Great cleanup of debug messages. LOCAL_DEBUG turned off in most modules,
several debug() calls converted to DBG().

bf8558bc9c Converted shutdown to a kind of reconfiguration, it's no more handled
as a exception in protocol state machines. Introduced a `shutdown'
CLI command. Killed few reconfiguration bugs.

50fe90edf3 First attempt on dynamic reconfiguration. There are still lots of bugs
and problems to solve, but the hardest part works.

f545d38707 Added universal locking mechanism which will solve problems
with protocols wanting to use the same port on the same interface
during reconfiguration time.

How to use locks: In the if_notify hook, just order locks for the
interfaces you want to work with and do the real socket opening after the
lock hook function gets called. When you stop using the socket, close
it and rfree() the lock.

Please update your protocols to use the new locking mechanism.

a0c37b45e5 Logging is now configurable. You can define multiple log outputs (to both
files and syslog) and assign lists of message categories to each of them.

7e5f5ffdda Moved to a much more systematic way of configuring kernel protocols.
o  Nothing is configured automatically. You _need_ to specify
     the kernel syncer in config file in order to get it started.
  o  Syncing has been split to route syncer (protocol "Kernel") and
     interface syncer (protocol "Device"), device routes are generated
     by protocol "Direct" (now can exist in multiple instances, so that
     it will be possible to feed different device routes to different
     routing tables once multiple tables get supported).

See doc/bird.conf.example for a living example of these shiny features.

7a2105becd Use dmalloc instead of EFence when available (dmalloc has lot of improvements
over EFence and also hopefully smaller memory overhead, but sadly it's non-free
for commercial use).

If the DMALLOC_OPTIONS environment variable is not set, switch on `reasonable'
checks by default.

Also introduced mb_allocz() for cleared mb_alloc().

2d14045224 Rewrote the kernel syncer. The old layering was horrible.
The new kernel syncer is cleanly split between generic UNIX module
and OS dependent submodules:

  -  krt.c (the generic part)
  -  krt-iface (low-level functions for interface handling)
  -  krt-scan (low-level functions for routing table scanning)
  -  krt-set (low-level functions for setting of kernel routes)

krt-set and krt-iface are common for all BSD-like Unices, krt-scan is heavily
system dependent (most Unices require /dev/kmem parsing, Linux uses /proc),
Netlink substitues all three modules.

We expect each UNIX port supports kernel routing table scanning, kernel
interface table scanning, kernel route manipulation and possibly also
asynchronous event notifications (new route, interface state change;
not implemented yet) and build the KRT protocol on the top of these
primitive operations.

test the whole protocol shutdown code... :)

41183888ee Properly initialize filters. Also bumped version to 0.0.0 as it
actually does something.

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

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.

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.

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.

routing protocol instances.

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.

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.
