4761efdb43 Tracing of CLI connections/commands can be now controlled 
by `debug commands <level>' in the configuration. Level 0 means
no tracing, 1 means connections only, 2 includes all commands.

f990fc61e0 When in persist mode, don't delete routes from kernel tables even if 
they cease to exist in our routing tables due to protocols having shut down.

0e5aa966cc Multicast problems should be gone, although the fix is Linux only and we'll 
need to figure out something better when working on new ports.

f9254d2349 Autoconf is *evil*. The sysconfdir and similar variables are unusable in 
C includes as they contain substitutions specific to make.

Worked around by creating sysconf/paths.h which is created from
the Makefile instead of by the configure script.
 2000-05-08 14:19:47 +00:00

818ff1e2b7 When reporting a bug(), call abort() instead of exit(), so that we 
can analyse the core.

9cbf43eb8a Don't report refused connections. 2000-05-08 12:09:10 +00:00
Martin Mares
b6c9d8eb2e Removed the `async' switch which was used for debugging only anyway. 
Don't moan when netlink reports lost packets.

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.
 2000-05-04 20:52:28 +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.)

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!
 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.

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.
 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.

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
Martin Mares
6b9fa32080 Great cleanup of debug messages. LOCAL_DEBUG turned off in most modules, 
several debug() calls converted to DBG().
 2000-03-12 21:01:38 +00:00
Martin Mares
c801e1fbab Renamed command shutdown' to down', so that `s' can be used as an 
abbreviation for `show'.
 2000-03-07 20:09:35 +00:00
Martin Mares
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.
 2000-02-29 23:19:52 +00:00
Martin Mares
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.
 2000-01-19 15:07:00 +00:00
Martin Mares
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
Martin Mares
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.
 2000-01-18 10:39:30 +00:00
Martin Mares
fb89b1a4ce Removed point-to-point tunnel hack as it breaks ordinary PtP interfaces. 
I'll find a better solution soon.
 2000-01-17 12:40:00 +00:00
Martin Mares
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.

99278e1042 Wording changes. 2000-01-16 23:36:19 +00:00
Martin Mares
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
Martin Mares
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.
 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
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.

30bc402ebb Temporary work-arounds for multicast problems. Needs further investigation. 1999-12-08 15:12:54 +00:00
Martin Mares
0da472d7e8 Except for special protocols (nowadays only the kernel syncer), don't 
export host and link scope routes.
 1999-12-08 14:16:13 +00:00

dc82daaa9b - Path to control socket is selectable via command-line option. 
- die() when control socket open failed.
 1999-12-08 13:20:19 +00:00

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.
 1999-12-06 13:45:56 +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
34350a5270 Implemented echoing of log messages to CLI connections. Just try `echo all'. 1999-12-06 12:34:45 +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
2727bb7c5b Renamed attr->attrs to attr->eattrs. 1999-11-04 13:29:43 +00:00
Martin Mares
b9672a845f The CLI I/O functions work as desired. 1999-10-31 15:43:44 +00:00

7d3aab1c16 First steps of the Command Line Interface: I/O routines. 1999-10-29 12:10:10 +00:00
Martin Mares
b93abffae4 Implemented unix-domain sockets. 1999-10-29 12:09:29 +00:00
Martin Mares
54165b1315 Configure PATH_CONTROL_SOCKET. 
autoconf.h is now written to obj/sysdep, the source tree is hopefully
completely read-only now.
 1999-10-29 10:08:09 +00:00
Martin Mares
ed6081502a Added skeleton of the client. Does nothing, but at least compiles. 1999-10-29 09:44:44 +00:00

f651941402 Added a function for generating 32-bit random numbers. 1999-08-17 20:47:40 +00:00
Martin Mares
4532a89e31 Taught Netlink how to behave in IPv6 world. 1999-08-03 19:37:37 +00:00
Martin Mares
4f22c98185 Support for IPv6 sockets. How nice one doesn't have to ifdef around 
ten years of API evolution :-)
 1999-08-03 19:36:51 +00:00
Martin Mares
dce267832a Basic support for IPv6. The system-dependent part doesn't work yet, 
but the core routines are there and seem to be working.

   o  lib/ipv6.[ch] written
   o  Lexical analyser recognizes IPv6 addresses and when in IPv6
      mode, treats pure IPv4 addresses as router IDs.
   o  Router ID must be configured manually on IPv6 systems.
   o  Added SCOPE_ORGANIZATION for org-scoped IPv6 multicasts.
   o  Fixed few places where ipa_(hton|ntoh) was called as a function
      returning converted address.
 1999-08-03 19:36:06 +00:00
Martin Mares
7de45ba4a0 Kernel route syncer supports multiple tables. 
The changes are just too extensive for lazy me to list them
there, but see the comment at the top of sysdep/unix/krt.c.
The code got a bit more ifdeffy than I'd like, though.

Also fixed a bunch of FIXME's and added a couple of others. :)
 1999-08-03 19:33:22 +00:00
Martin Mares
9273035403 Changes to interface handling on traditional Unices: 
o  Aliases are interpreted as secondary addresses.
  o  When the system doesn't supply interface indices, generate
     our ones.
 1999-08-03 19:30:20 +00:00
Martin Mares
913f7dc9f2 Added functions for parsing and formatting of dates. 1999-08-03 19:29:27 +00:00
Martin Mares
bd7f1081f2 Grrr, the "obvious fix" to multicasting code from yesterday was 
fundamentally wrong. Reversed.
 1999-06-01 15:31:43 +00:00
Martin Mares
c7208da0b7 Fix potential multicasting bug. 1999-05-31 20:28:46 +00:00
Martin Mares
bb027be1e2 Added extra argument to rt_update hook which contains a pointer to the 
temporary attribute list.
 1999-05-31 18:55:35 +00:00
Martin Mares
4b0d57e531 Added CONFIG_MULTIPLE_TABLES whereever appropriate. 1999-05-21 14:29:44 +00:00
Martin Mares
1c3c9dceb3 Removed one unused structure field. 1999-05-21 14:29:23 +00:00
Martin Mares
4f1a6d27b9 Kill remaining master_table relics in KRT code. 
Make all protocols pass routing table to rte_update and rte_discard.
 1999-05-17 20:16:53 +00:00
Martin Mares
a2697f02ac Netlink support for secondary interface addresses. 1999-05-07 13:46:16 +00:00
Martin Mares
9a158361da I rewrote the interface handling code, so that it supports multiple 
addresses per interface (needed for example for IPv6 support).

Visible changes:

o  struct iface now contains a list of all interface addresses (represented
   by struct ifa), iface->addr points to the primary address (if any).
o  Interface has IF_UP set iff it's up and it has a primary address.
o  IF_UP is now independent on IF_IGNORED (i.e., you need to test IF_IGNORED
   in the protocols; I've added this, but please check).
o  The if_notify_change hook has been simplified (only one interface pointer
   etc.).
o  Introduced a ifa_notify_change hook. (For now, only the Direct protocol
   does use it -- it's wise to just listen to device routes in all other
   protocols.)
o  Removed IF_CHANGE_FLAGS notifier flag (it was meaningless anyway).
o  Updated all the code except netlink (I'll look at it tomorrow) to match
   the new semantics (please look at your code to ensure I did it right).

Things to fix:

o  Netlink.
o  Make krt-iface interpret "eth0:1"-type aliases as secondary addresses.
 1999-05-06 21:38:11 +00:00
Martin Mares
4c5e5e3a1c Multicasts once again: When using SO_BINDTODEVICE, don't specify IP address 
of the interface.
 1999-04-14 12:29:47 +00:00
Martin Mares
1b50a1e4be Next attempt to get SO_BINDTODEVICE work :) 1999-04-14 11:39:07 +00:00
Martin Mares
36154beb70 Use SO_BINDTODEVICE if we're using old multicast API (i.e., struct ip_mreq 
and not ip_mreqn). This should get multicasts on unnumbered PtP links work.
 1999-04-14 11:21:02 +00:00
Martin Mares
01bd7759b2 Ignore alias interfaces (some day, we will treat them as pure secondary 
interface addresses).
 1999-04-12 18:07:05 +00:00
Martin Mares
08e2d6259a Removed TOS support. This simplifies many things a lot. 1999-04-12 18:01:07 +00:00
Martin Mares
61fb537c62 Use struct ip_mreqn' instead of struct ip_mreq' for multicast 
operations on 2.1/2.2 kernels. This allows passing of real interface
indexes instead of referencing interfaces by their IP addresses which
fails badly in presence of unnumbered interfaces.

Unfortunately, this structure is not visible with glibc 2.0 as it provides
its own networking headers :-(  Both libc5 and glibc 2.1 should be OK.
 1999-04-12 15:27:56 +00:00
Martin Mares
5a99ade413 Fixed a couple of bugs in handling of multicast sockets. 
See comments in lib/socket.h for a detailed guide on how to use them.
