b6c9d8eb2e Removed the `async' switch which was used for debugging only anyway. 
Don't moan when netlink reports lost packets.

94e935d8a2 Incoming buffer must be at least 8KB long. 2000-05-08 11:02:53 +00:00

1151401e2b Don't crash when reporting deleted routes.

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.

93a786cb03 Removed a lot of unused variables. 
Please try compiling your code with --enable-warnings to see them. (The
unused parameter warnings are usually bogus, the unused variable ones
are very useful, but gcc is unable to control them separately.)

2edb31b097 Split CF_HDR section to CF_HDR (only includes) and CF_DEFINES (defines, 
C declarations etc.).

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.

f2cb1d708d Dropped CPU_NEEDS_ALIGN_* as unaligned.h no longer uses them. 2000-04-10 12:38:15 +00:00
Martin Mares
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.

a37410cbdd Use bsprintf() instead of sprintf(). 2000-03-31 23:33:03 +00:00
Martin Mares
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.
 2000-03-30 10:43:37 +00:00

1cf716f075 Handle EINPROGRESS properly. 
Set IP_DONTROUTE sockopt only if sk->ttl == 1.

a92bebe0ec Yet another LOCAL_DEBUG turned off. 2000-03-12 21:58:51 +00:00
Martin Mares
832fa033b7 Cleaned up debugging in kernel syncer. Netlink has still LOCAL_DEBUG 
turned on, but after some testing I'll gag it.
 2000-03-12 21:54:39 +00:00

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

c801e1fbab Renamed command shutdown' to down', so that `s' can be used as an 
abbreviation for `show'.

b9626ec6ea Garbage collector events and counters are now per table and one day 
they can be made configurable if it turns out to be useful.

d07bab3997 ipa_opposite hack is not applicable in IPv6. 2000-03-01 11:29:30 +00:00
Martin Mares
6a636392d3 Rewrote interface type detection logic. The `unnumbered' flag is now per 
address, not per interface (hence it's ifa->flags & IA_UNNUMBERED) and
should be set reliably. IF_MULTIACCESS should be fixed now, but it isn't
wise to rely on it on interfaces configured with /30 prefix.

9fac310d1a Put client on a stony ground. The whole client is going to be system-specific 
(the current version UNIX-specific) anyway, so it's useless to try splitting it
to sysdep and generic part. Instead of this, configure script decides (based on
system type and user's wish) what (if any) client should be built and what
autoconfiguration it requires. Also, the client provides its own die/bug/...
functions.

3ea1ba632b Killed protocol->priority. Protocol startup should be clean and hack-free now. 
It seems everything still works (except for disable/enable/restart which hangs
sometimes, but it's another story).
 2000-01-18 11:01:03 +00:00

aa8761de94 Kernel route syncer now supports dynamic reconfiguration. Also it doesn't 
depend on the startup counter hack now and uses a zero-time timer instead
to make itself scheduled after normal protocol startup.

fb89b1a4ce Removed point-to-point tunnel hack as it breaks ordinary PtP interfaces. 
I'll find a better solution soon.

d272fe22dd Separated `official protocol names' used in status dumps from name templates 
used for automatic generation of instance names.

	protocol->name is the official name
	protocol->template is the name template (usually "name%d"),
		should be all lowercase.

Updated all protocols to define the templates, checked that their configuration
grammar includes proto_name which generates the name and interns it in the
symbol table.

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.
 2000-01-16 17:40:26 +00:00

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

e693ddff87 Handle cases when SIOCGIFINDEX is defined, but doesn't work (new glibc 
with 2.0 kernels).
 1999-12-16 13:23:32 +00:00

a2867cd957 Better order of includes. 
set_inaddr() moved to sysio.h.

67ece6df42 Tried to clean up multicast handling. Now we don't try to guess 
multicast abilities depending on definedness of symbols and use hard-wired
system-dependent configuration defines instead.

Please test whereever you can.

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.

0da472d7e8 Except for special protocols (nowadays only the kernel syncer), don't 
export host and link scope routes.

dc82daaa9b - Path to control socket is selectable via command-line option. 
- die() when control socket open failed.

f78056fb2c Allow logging to stderr as well. 1999-12-06 13:51:04 +00:00
Martin Mares
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.

a9c986f981 Added tracked_fopen() which is a fopen registered in resource database. 
Will be used for log files.

34350a5270 Implemented echoing of log messages to CLI connections. Just try `echo all'. 1999-12-06 12:34:45 +00:00
