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).

3d574679b8 Fix bugs related to kernel table synchronization.
KRF_INSTALLED flag was not cleared during reconfiguration
that lead to not removing routes during reconfigure when
export rules changed.

We also should not try to remove routes we didi not installed,
on Linux this leads to warnings (as kernel checks route source
field and do not allow to remove non-bird routes) but we should
not rely on it.

1567edea8d Bugfix for routing table breaking bug.
Here is a patch fixing a bug that causes breakage of a local routing
table during shutdown of Bird. The problem was caused by shutdown
of 'device' protocol before shutdown of 'kernel' protocol.  When
'device' protocol went down, the route (with local network prefix)
From different protocol (BGP or OSPF) became preferred and installed
to the kernel routing table. Such routes were broken (like
192.168.1.0/24 via 192.168.1.2). I think it is also the cause
of problem reported by Martin Kraus.

The patch disables updating of kernel routing table during shutdown of
Bird. I am not sure whether this is the best way to fix it, I would
prefer to forbid 'kernel' protocol to overwrite routes with
'proto kernel'.

The patch also fixes a problem that during shutdown sometimes routes
created by Bird remained in the kernel routing table.

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.

(thanks to Andreas for the original idea)
2004-05-31 22:00:18 +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.

5f2a6a9ff3 Fix handling on full pipe to client in bird. Prevent packet overflows
for even only medium sized route table output. Fix a strange garbled
output problem in the client. The latter seems to be caused by some
library doing tcflush while there is still command output pending. So
the best fix here is to do fflush and then tcdrain. Note that this
problem occurs only under certain load situations and is not too easy to
reproduce.

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.)

to work fine.

Now I run three BGP connections with several thousand routes!

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.

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.

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.

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.

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

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.

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.

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.

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. :)

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.

4c5e5e3a1c Multicasts once again: When using SO_BINDTODEVICE, don't specify IP address

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.

01bd7759b2 Ignore alias interfaces (some day, we will treat them as pure secondary
interface addresses).

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.
