3549667925 Implemented real slab allocator. If you suspect it from being buggy,
just #define FAKE_SLAB at the top of lib/slab.c to bypass it.

12a9d139ee ipv6_compare() accepts non-lvalue arguments as well. This makes filters
compile with IPv6.

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.

0d70292d88 Events now return a value. If it's non-zero, the event is re-queued
for processing in next event cycle. This can be used to prevent background
actions (hint: user commands) from hogging the CPU for too long time.

4f22c98185 Support for IPv6 sockets. How nice one doesn't have to ifdef around
ten years of API evolution :-)

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.

3e1f30610e Defined IP_PREC_INTERNET_CONTROL and made all (well, both :)) protocols
use it when creating sockets.

ec8b579e9c Recognize site scope for IPv4 addresses (prefixes reserved for private
networks).

Removed old #ifndef logic which was used to avoid IPv4/IPv6 clashes
before conditionals in Modules lists were introduced.

5a99ade413 Fixed a couple of bugs in handling of multicast sockets.

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.

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().

b4b3b39e20 Added SK_MAGIC type sockets for internal use by system dependent code,
especially for netlink communication.

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

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

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.

a05406e69c Implemented deletion/insertion/asynchronous-walk lists.
For example of their use, look at comments in lib/slists.h.

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.

matching interface names in protocol-to-iface bindings.

53a416d376 Implemented snprintf and similar functions. It took a lot of thinking,
but the modifications were relatively simple and straightforward.

ab3a76a382 Added ipa_from_u32 and ipa_from_u32 for use in the kernel sync code (IPv4 only).
Don't ever think of using it in routing protocols.

d92882be9b WALK_LIST_DELSAFE now actually works (it really couldn't since it didn't
reference list head at all).
