53943a0022 Defined format specifier %M' which behaves as %m', but takes the 
error code as an argument.

Use it in socket hooks where we really shouldn't rely on errno containing
the right value or even existing.

8f6accb5bb Event handlers no longer return re-queue flag. Instead of using it, just 
call ev_schedule() on the same handler which should work perfectly now.

221135d6bf Include "lib/string.h" instead of <string.h>. It should give us bzero() 
and other non-portable functions on all systems.

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.

xmalloc to bird_xmalloc internally.

e68dd11c43 Use do { } while(0) instead of empty DBG if not debugging. 2000-03-12 21:47:25 +00:00

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.

ea32afb765 Added ip_scope_text() for translating of scopes to strings. 1999-11-25 15:34:20 +00:00

84a7d7f77c ev_run() now returns whether the event has been requeued or not. 
ev_run_list() now returns number of events which remain in the list.

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. 
See comments in lib/socket.h for a detailed guide on how to use them.

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.

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

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
