48e5f32db6 Many changes in I/O and OSPF sockets and packet handling. 
I/O:
 - BSD: specify src addr on IP sockets by IP_HDRINCL
 - BSD: specify src addr on UDP sockets by IP_SENDSRCADDR
 - Linux: specify src addr on IP/UDP sockets by IP_PKTINFO
 - IPv6: specify src addr on IP/UDP sockets by IPV6_PKTINFO
 - Alternative SKF_BIND flag for binding to IP address
 - Allows IP/UDP sockets without tx_hook, on these
   sockets a packet is discarded when TX queue is full
 - Use consistently SOL_ for socket layer values.

OSPF:
 - Packet src addr is always explicitly set
 - Support for secondary addresses in BSD
 - Dynamic RX/TX buffers
 - Fixes some minor buffer overruns
 - Interface option 'tx length'
 - Names for vlink pseudoifaces (vlinkX)
 - Vlinks use separate socket for TX
 - Vlinks do not use fixed associated iface
 - Fixes TTL for direct unicast packets
 - Fixes DONTROUTE for OSPF sockets
 - Use ifa->ifname instead of ifa->iface->name

collides with usage 0 as a special value in timer->expires field.

c429d4a4ba Restrict export of device routes to the kernel protocol. 
In usual configuration, such export is already restricted
with the aid of the direct protocol but there are some
races that can circumvent it. This makes it harder to
break kernel device routes. Also adds an option to
disable this restriction.

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).

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.

This is done to avoid clashes with gcc-3.3 which has built-in logarithms :)

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.

f9254d2349 Autoconf is *evil*. The sysconfdir and similar variables are unusable in

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

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.

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.

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. :)

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.

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

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.

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.

c10421d3d4 More changes to the kernel syncer. 
o  Now compatible with filtering.
o  Learning of kernel routes supported only on CONFIG_SELF_CONSCIOUS
   systems (on the others it's impossible to get it semantically correct).
o  Learning now stores all of its routes in a separate fib and selects
   the ones the kernel really uses for forwarding packets.
o  Better treatment of CONFIG_AUTO_ROUTES ports.
o  Lots of internal changes.
 1999-04-03 13:05:18 +00:00

73c7bed168 Defined CONFIG_SELF_CONSCIOUS whenever the kernel scanner is able
