fe9f1a6ded Initial commit on integrated BIRD 
New data types net_addr and variants (in lib/net.h) describing
network addresses (prefix/pxlen). Modifications of FIB structures
to handle these data types and changing everything to use these
data types instead of prefix/pxlen pairs where possible.

The commit is WiP, some protocols are not yet updated (BGP, Kernel),
and the code contains some temporary scaffolding.

Comments are welcome.

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

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).

Prefix sets were broken beyond any repair and have to be reimplemented.

but the old interpretation was already inconsistent with
the documentation and broken.

There is also some bugfixes in filter code related to set variables.

b933281ed5 Fixes nasty bug in event processing. 
WALK_LIST_DELSAFE (in ev_run_list) is not safe with regard
to deletion of next node. When some events are rescheduled
during event execution, it may lead to deletion of next
node and some events are skipped. Such skipped nodes remain
in temporary list on stack and the last of them contains
'next' pointer to stack area. When this event is later
scheduled, it damages stack area trying to remove it from
the list, which leads to random crashes with funny
backtraces :-) .

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.

30b773041c IP address formatting now uses the same rules as formatting of strings 
with two exceptions:

   o  Any non-zero field width is automatically replaced by standard
      IP address width. This hides dependences on IPv4/IPv6.
   o  %#I generates hexadecimal form of the address.

Therefore |%I| generates unpadded format, |%1I| full size flush-right,
and |%-1I| full size flush-left format.

93a786cb03 Removed a lot of unused variables. 
Please try compiling your code with --enable-warnings to see them. (The

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.

Martin Mares
f5c687f791 Added lp_flush() which flushes contents of a linear pool, leaving all the 
memory available for subsequent allocations from the same pool. Both flushing
and re-using the memory costs just few instructions.
 1999-03-29 19:35:47 +00:00
Martin Mares
f54801ffed Moved all system-dependent #include's containing endianity conversion 
functions to sysdep header endian.h.

6134024815 #define NULL if not defined by system includes. 1999-03-29 19:13:36 +00:00
Martin Mares
7a2105becd Use dmalloc instead of EFence when available (dmalloc has lot of improvements 
over EFence and also hopefully smaller memory overhead, but sadly it's non-free
for commercial use).

If the DMALLOC_OPTIONS environment variable is not set, switch on `reasonable'
checks by default.

Also introduced mb_allocz() for cleared mb_alloc().
 1999-03-04 11:36:26 +00:00
Martin Mares
b4b3b39e20 Added SK_MAGIC type sockets for internal use by system dependent code, 
especially for netlink communication.
 1999-03-01 22:30:33 +00:00

67bd949a52 Real implementation of protocol state machines. Delayed startup/shutdown 
should work now. Initial feeding of protocols by interfaces/routes is
done from the event queue to prevent unwanted recursion.

3b15402fd4 Grrr, forgot to commit the event routines themselves :| 1999-02-11 22:18:36 +00:00
Martin Mares
e8f73195fa Added simple event scheduling system to avoid recursive calling 
of various callbacks.

Events are just another resource type objects (thus automatically freed
and unlinked when the protocol using them shuts down). Each event can
be linked in at most one event list. For most purposes, just use the
global event list handled by the following functions:

	ev_schedule	Schedule event to be called at the next event
			scheduling point. If the event was already
			scheduled, it's just re-linked to the end of the list.
	ev_postpone	Postpone an already scheduled event, so that it
			won't get called. Postponed events can be scheduled
			again by ev_schedule().

You can also create custom event lists to build your own synchronization
primitives. Just use:

	ev_init_list	to initialize an event list
	ev_enqueue	to schedule event on specified event list
	ev_postpone	works as well for custom lists
	ev_run_list	to run all events on your custom list
	ev_run		to run a specific event and dequeue it

294c182eb1 Replaced the old ugly ipv6 compilation hack by a conditional in Modules. 1999-01-23 21:08:59 +00:00
Martin Mares
98e87c8628 Finer grained logging levels: 
#define L_DEBUG "\001"   /* Debugging messages */
#define L_INFO "\002"    /* Informational messages */
#define L_WARN "\003"    /* Warnings */
#define L_ERR "\004"     /* Errors */
#define L_AUTH "\005"    /* Authorization failed etc. */
#define L_FATAL "\006"   /* Fatal errors */
#define L_TRACE "\002"   /* Protocol tracing */
#define L_INFO "\003"    /* Informational messages */
#define L_REMOTE "\004"  /* Remote protocol errors */
#define L_WARN "\004"    /* Local warnings */
#define L_ERR "\005"     /* Local errors */
#define L_AUTH "\006"    /* Authorization failed etc. */
#define L_FATAL "\007"   /* Fatal errors */
#define L_BUG "\010"     /* BIRD bugs */

Introduced bug() which is like die(), but with level L_BUG. Protocols
should _never_ call die() as it should be used only during initialization
and on irrecoverable catastrophic events like out of memory.

Also introduced ASSERT() which behaves like normal assert(), but it calls
bug() when assertion fails. When !defined(DEBUGGING), it gets ignored.

a6f250f5c6 New hash functions according to benchmarks posted yesterday. (The IPv6 
version has not been benchmarked yet due to insufficient test data.)
Now ipa_hash() returns a uniformely distributed 16-bit value.
 1998-12-20 13:57:49 +00:00
Martin Mares
a05406e69c Implemented deletion/insertion/asynchronous-walk lists.

Martin Mares
b35d72ac66 Name cleanups as suggested by Pavel: 
- cfg_strcpy() -> cfg_strdup()
- mempool -> linpool, mp_* -> lp_*  [to avoid confusion with memblock, mb_*]

Anyway, it might be better to stop ranting about names and do some *real* work.
 1998-12-06 11:59:18 +00:00

 1998-07-10 08:39:34 +00:00
Martin Mares
786d0bb9e7 Added ipa_class_mask() which guesses netmask for classful addressing. 
For pure A/B/C class addresses it just returns the class netmask, for
subnets it tries to guess subnet mask. Please make sure the address
you pass to this function is really a valid host address (i.e., call
ipa_validate() first).
