Ondrej Zajicek 8931425d02 Fixes problem with RIP on multiple ifaces on BSD. 
RIP sockets for multiple ifaces collided, because we cannot bind to
a specific iface on BSD. Workarounded by SO_REUSEPORT.

Thanks to Eugene M. Zheganin for the bugreport.

 2010-07-12 17:39:39 +02:00
Ondrej Zajicek acb60628f5 Implements command that shows memory usage. 2010-06-02 22:20:40 +02:00
Ondrej Zajicek 002b642318 Fixes bug on Linux 2.4.x - kernel sync does not work until restart of kernel protocol. 
Which was, actually, a bug in timers - on older kernel, monotonic timer
is missing and the other implementation started with now == 0, which
collides with usage 0 as a special value in timer->expires field.

  when cannot open control socket.
- Fixes socket name path check and other error handling in CLI init.
 2010-03-17 12:19:22 +01:00
Ondrej Zajicek 54305181f6 Merge branch 'new' into socket2 2010-03-11 18:55:59 +01:00

 2010-02-26 10:55:58 +01:00
Ondrej Zajicek e81b440f68 Fix configure to enable warnings and fix most of them. 2010-02-21 14:34:53 +01:00
Ondrej Zajicek 2af25a971a Fixes a crash caused by missing error hook on BGP listening socket. 
Error happened when too many BGP connections arrived in one moment
(ECONNABORTED).
 2010-02-11 11:12:58 +01:00

Ondrej Zajicek ea89da381f Workaround for stupid callback scheduler. 
There is no reak callback scheduler and previous behavior causes
bad things during hard congestion (like BGP hold timeouts).

Smart callback scheduler is still missing, but main loop was
changed such that it first processes all tx callbacks (which
are fast enough) (but max 4* per socket) + rx callbacks for CLI,
and in the second phase it processes one rx callback per
socket up to four sockets (as rx callback can be slow when
there are too many protocols, because route redistribution
is done synchronously inside rx callback). If there is event
callback ready, second phase is skipped in 90% of iterations
(to speed up CLI during congestion).
 2009-10-11 18:56:16 +02:00
Ondrej Zajicek daeeb8e982 Clear memory allocated by ralloc(). 
This also fixes bug that timer->recurrent was not cleared
in tm_new() and unexpected recurrence of startup timer
in BGP confused state machine and caused crash.
 2009-09-04 11:24:08 +02:00
Ondrej Zajicek f9c799a00e Temporary OSPFv3 development commit (changing multicast support). 2009-09-04 11:06:51 +02:00
Ondrej Zajicek 061ab802a6 Temporary OSPFv3 development commit 2009-08-27 18:25:46 +02:00
Ondrej Zajicek 2d785e8d6a Fixes bug on TCP passive socket binding on BSD. 
BGP on BSD was bound to random port. I am surprised that
nobody noticed it already.
 2009-06-26 13:33:41 +02:00
Ondrej Zajicek 1876e18d32 Minor bugfix. 2009-06-25 15:44:43 +02:00
Ondrej Zajicek 4323099da9 Fixes bug in scheduling of callback by main loop. 
If other side of a socket is sending data faster than
BIRD is processing, BIRD does not schedule any other
callbacks (events, timers, rx/tx callbacks).
 2009-06-20 00:59:32 +02:00
Ondrej Zajicek 789772ed45 Implements option that changes BGP listening socket parametres. 2009-06-18 19:20:07 +02:00
Ondrej Filip 2b70f0742e Linux specific TCP-MD5 handling moved to sysdep/linux/sysio.h 
FreeBSD coded added. BSD cannot set BGP passwords itself.
This has to be done by external command.
 2009-05-04 18:17:46 +02:00
Ondrej Zajicek 35164c5017 rx_hook may be cleaned in some callback so we check it before 
executing sk_read().

Ondrej Zajicek a39b165e45 Multihop BGP was completely broken, because listening socket has always 
ttl 1.

Ondrej Filip c025b85273 Real write is only in sk_maybe_write. Previous change partially reverted. 
Thank you MJ.
 2005-02-14 23:15:04 +00:00
Ondrej Filip 7c49f71559 Added s->err_hook wrapper that empties socket. 2005-02-14 21:28:51 +00:00
Ondrej Filip 0d3effcf8c Time added in password management. 2005-02-12 22:27:55 +00:00

Ondrej Filip 41c8976e29 Test old instance of BIRD. 2004-06-06 17:05:25 +00:00
Martin Mares 4da25acb0a Cleaned up sk_reallocate() and friends. 
Also, removed the `if (s)' test, because I believe that as the whole
socket interface doesn't accent NULL pointers, sk_reallocate() shouldn't
be the only exception.
 2004-06-05 08:56:43 +00:00
Ondrej Filip e7ef86a58c OSPF is ready for changing MTU. 2004-06-04 18:51:29 +00:00
Ondrej Filip 7d72aadb8a CONFIG_SKIP_MC_BIND added. 
BSD hates it, Linux needs it.
 2004-06-03 08:18:14 +00:00
Ondrej Filip b613b9928b #ifdef CONFIG_UNIX_DONTROUTE added. 2004-06-01 10:32:02 +00:00
Martin Mares 38a608c55a Rewritten the I/O loop. All socket operations are now safe, meaning that 
you can delete the socket from anywhere in the hooks and nothing should break.
Also, the receive/transmit buffers are now regular xmalloc()'ed buffers,
not separate resources which would need shuffling around between pools.

sk_close() is gone, use rfree() instead.
 2004-05-31 21:48:19 +00:00
Ondrej Filip b1a1fabac7 *BSD port added. (Tested on FreeBSD and NetBSD) 2004-05-31 13:25:00 +00:00
Martin Mares 01b776e117 Fixed <time.h> vs. <sys/time.h> problems. 2001-03-06 13:40:39 +00:00
Martin Mares 0b3bf4b1d8 Use SUN_LEN() for length of UNIX domain addresses. This should fix problems 
with connection to clients on libc5 machines.
 2000-06-09 07:30:22 +00:00
Martin Mares 58f7d004fd Fixes to the progdoc. 2000-06-07 13:25:53 +00:00
Martin Mares 2e9b24211a Spelling fixes to progdoc. 2000-06-07 12:29:08 +00:00
Martin Mares 525fa2c1f0 Documented sockets, events and timers. 2000-06-05 12:19:12 +00:00
Martin Mares 10304bed43 Split random number functions off io.c, so that they can be documented 
separately.
 2000-06-05 11:46:40 +00:00
Martin Mares b594ad2386 tm_format_reltime() works with both past and future timestamps. 2000-06-01 15:13:23 +00:00
Martin Mares c304392e65 Some less socket error messages. 2000-05-08 12:37:39 +00:00
Martin Mares 9cbf43eb8a Don't report refused connections. 2000-05-08 12:09:10 +00:00
Martin Mares 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.)
 2000-05-04 20:30:36 +00:00
Martin Mares 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!
 2000-04-27 22:35:08 +00:00
Martin Mares 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.
 2000-04-26 13:26:11 +00:00
Martin Mares 0cadd5f531 Removed several FIXME's. 2000-04-26 12:33:37 +00:00
Martin Mares 00c0c18aea Allow sk_close(NULL). 2000-04-25 23:07:47 +00:00
Martin Mares f380aa60fa IPv6 compiles with glibc 2.1. 2000-04-20 23:05:41 +00:00
Martin Mares 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.
 2000-03-31 23:30:21 +00:00
Martin Mares 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
Martin Mares 1cf716f075 Handle EINPROGRESS properly. 
Set IP_DONTROUTE sockopt only if sk->ttl == 1.
 2000-03-20 21:49:21 +00:00
Martin Mares f098e072be Fixed a bunch of FIXME's by removing them :) 2000-03-12 22:53:05 +00:00
Martin Mares 7a88832e78 Added tm_format_datetime(). 2000-03-12 22:43:13 +00:00
Martin Mares a2867cd957 Better order of includes. 
set_inaddr() moved to sysio.h.
 1999-12-16 13:14:02 +00:00
Martin Mares 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.
 1999-12-16 13:06:13 +00:00
Martin Mares 30bc402ebb Temporary work-arounds for multicast problems. Needs further investigation. 1999-12-08 15:12:54 +00:00
Martin Mares f78056fb2c Allow logging to stderr as well. 1999-12-06 13:51:04 +00:00
Martin Mares a9c986f981 Added tracked_fopen() which is a fopen registered in resource database. 
Will be used for log files.
 1999-12-06 13:43:47 +00:00
Martin Mares afa8937ac8 Added tm_format_reltime() for formatting of relative time quantities. 1999-12-01 11:59:00 +00:00
Martin Mares 487d1afa52 Moved TIME_INFINITY to timer.h, so that it's publicly available. 1999-11-30 14:01:39 +00:00
Martin Mares 30770df2ab If the main event queue is not empty, call select() with zero timeout, so 
that the events are ran again after the FD's are checked. This allows us
to schedule I/O checks between processing of user commands.
 1999-11-17 12:04:24 +00:00
Martin Mares b93abffae4 Implemented unix-domain sockets. 1999-10-29 12:09:29 +00:00
Martin Mares f782b72c53 Failure to set socket TOS is not a fatal error. 1999-10-02 11:06:44 +00:00
