Ondrej Zajicek 54d70d3ebb Fixes compiler warning in OFFSETOF(). 2009-07-23 22:21:17 +02:00
Ondrej Zajicek 2f6483cd31 Adds %R printf directive for Router ID. 2009-07-23 16:06:25 +02:00
Ondrej Zajicek d1abbeacfb Fixes memory alignment problems on Sparc64. 
Not quite standard construction, i should add
some autoconf macro.

Not tested yet.
 2009-07-06 19:07:01 +02:00
Ondrej Zajicek 789772ed45 Implements option that changes BGP listening socket parametres. 2009-06-18 19:20:07 +02:00
Ondrej Zajicek 1b3b3e34ec Minor bugfixes. 2009-06-18 14:32:44 +02:00
Ondrej Zajicek 3d15dcdb1c Changes OSPF to generate stub networks for non-primary addresses. 
Also does some reorganization in RT LSA announcement.
 2009-06-10 23:45:08 +02:00
Ondrej Zajicek c60cdd8c39 Cleanup changes 2009-03-31 21:17:00 +02:00
Ondrej Zajicek b1a597e0c3 Reimplementation of prefix sets. 
Prefix sets were broken beyond any repair and have to be reimplemented.
They are reimplemented using a trie with bitmasks in nodes.
There is also change in the interpretation of minus prefix pattern,
but the old interpretation was already inconsistent with
the documentation and broken.

There is also some bugfixes in filter code related to set variables.
 2009-03-31 12:55:57 +02:00
Ondrej Zajicek cb53039271 Rate limit for most abundant log messages 2009-02-26 14:23:54 +01:00
Ondrej Zajicek 02a9eeeb85 Slist update 2009-01-12 14:40:21 +01:00
Ondrej Zajicek 083c43e22e fixes some 64-bit related bugs. 
Filter code used 'aux' integer field of 'symbol' struct to store ptr
to next symbol and both 'aux2' and 'def' fields for value.
Changed to just 'def' for value and 'aux2' for ptr to next symbol.
Also another minor bugfix.
 2008-12-25 11:55:27 +01:00
Ondrej Zajicek 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 :-) .
 2008-12-18 23:26:08 +01:00
Ondrej Zajicek a39b165e45 Multihop BGP was completely broken, because listening socket has always 
ttl 1.
 2008-11-01 16:58:40 +01:00
Ondrej Zajicek d51aa28190 Implementation of MD5 authentication of BGP sessions. 2008-10-26 22:42:39 +01:00
Martin Mares 057021df0d Fix behavior of ipa_opposite(). 
It was giving wrong results on /30 networks.
 2008-08-25 11:19:49 +00:00
Martin Mares 9831e5916f Staticized lots of local functions. 2004-06-05 09:58:23 +00:00
Martin Mares 2f6de49f8c Better prototypes. 2004-06-05 09:57:49 +00:00
Martin Mares fab37e8197 One more in the library. 2004-06-05 09:27:02 +00:00
Martin Mares e98bc2ea9b Renamed log() to log_msg(), but still keeping the old name as a macro. 
This is done to avoid clashes with gcc-3.3 which has built-in logarithms :)
 2004-06-05 09:05:12 +00:00
Martin Mares 5da8f82feb A better comment. 2004-06-05 09:01:12 +00:00
Ondrej Filip e7ef86a58c OSPF is ready for changing MTU. 2004-06-04 18:51:29 +00:00
Ondrej Filip 7fdd338c36 ALIGN -> BIRD_ALIGN 2004-06-01 10:28:25 +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.
 2004-05-31 21:48:19 +00:00
Martin Mares 206f59dfa8 Added UNUSED. 2004-05-31 21:02:09 +00:00
Martin Mares 2cc37815ae Added rmove() (by Andreas, tweaked by me). 2004-05-31 18:47:19 +00:00
Ondrej Filip 1bd897dd33 Changed of comments. 2004-05-31 17:27:21 +00:00
Ondrej Filip 7dbd4fd332 alloca.h added 2004-05-31 17:13:58 +00:00
Ondrej Filip 0e6eef620d Use #include "alloca.h" 2004-05-31 17:07:05 +00:00
Ondrej Filip 012279f395 Some include added. 2004-05-31 13:59:03 +00:00
Ondrej Filip d93fb7e6b9 #ifndef ALIGN - it is defined on *BSD 2004-05-31 13:58:38 +00:00
Martin Mares 47f18ac39a ABS should be a macro. 2002-11-13 08:47:19 +00:00
Martin Mares 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.
 2001-08-19 11:11:44 +00:00
Martin Mares 27e993fb4e Fixed duplicity in log category numbering. 
Thanks to Zheng Yuan for spotting this.
 2001-02-20 09:49:19 +00:00
Martin Mares 0766e962e9 Bug fix from Zheng Yuan <zyuan1@cig.mot.com>. 2001-01-17 08:32:28 +00:00
Martin Mares a2d01907c5 Added an explanatory comment. 2001-01-15 09:24:16 +00:00

Martin Mares 58f7d004fd Fixes to the progdoc. 2000-06-07 13:25:53 +00:00
Martin Mares 2e9b24211a Spelling fixes to progdoc. 2000-06-07 12:29:08 +00:00
Ondrej Filip 3df89cefc1 #define SIZE_OF_IP_HEADER 2000-06-07 01:18:36 +00:00
Martin Mares 525fa2c1f0 Documented sockets, events and timers. 2000-06-05 12:19:12 +00:00
Martin Mares 5cc1e1f805 Documented memory resources. 2000-06-05 11:41:41 +00:00
Martin Mares 7722938d63 Added library progdocs. 2000-06-04 18:34:39 +00:00
Martin Mares 38cf78a97a Added the introduction chapter of progdoc. 2000-05-31 13:30:58 +00:00
Martin Mares fcb5f4a725 Updated all the Doc files to new format. 2000-05-31 11:30:18 +00:00
Martin Mares cfa6ab0593 Added ipa_absolutize() which converts link-scope addresses to global scope 
ones according to prefix assigned to the corresponding interface.
 2000-05-30 22:47:33 +00:00
Martin Mares be77b6890c Poisoning: take there... 2000-05-16 15:02:33 +00:00
Martin Mares e2f4f27564 Oops, the poison was too deadly... 2000-05-16 13:53:44 +00:00
Martin Mares b8e60d3562 Added poisoning of free'd objects when we're debugging. 2000-05-16 13:51:31 +00:00
Martin Mares 758458be05 Unified parsing of prefixes. 
Had to rename `prefix' in filters to `fprefix'.
 2000-05-13 11:17:49 +00:00
Martin Mares c976342828 Implemented debugging function rlookup() which you can call from gdb 
to see what resource does the address given as a parameter belong to.
 2000-05-08 22:33:38 +00:00
Martin Mares ab1129c1bd Added skeleton Doc files for the whole developer's documentation. 2000-05-05 17:17:42 +00:00
Martin Mares 2a149b18cc Unused variables in IPv6 code. 2000-05-04 20:38:44 +00:00
Martin Mares 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.)
 2000-05-04 20:30:36 +00:00
Martin Mares 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.
 2000-05-02 16:10:04 +00:00
Martin Mares 85a291ff30 IPv6 address classification fixes. 2000-05-02 15:21:51 +00:00
Martin Mares 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.
 2000-04-27 22:28:49 +00:00
Martin Mares 7750634946 Introduced `ARRAY_SIZE' macro to replace all the sizeof(a)/sizeof(*a) constructs. 2000-04-12 13:21:23 +00:00
Martin Mares ac4b4683ae Removal of useless includes continues... 2000-03-31 23:40:00 +00:00
Martin Mares a37410cbdd Use bsprintf() instead of sprintf(). 2000-03-31 23:33:03 +00:00
Martin Mares 221135d6bf Include "lib/string.h" instead of <string.h>. It should give us bzero() 
and other non-portable functions on all systems.
 2000-03-31 23:30:21 +00:00
Martin Mares 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.
 2000-03-30 10:43:37 +00:00
Martin Mares 3ee2310c5d Avoid conflicts with libraries defining their own xmalloc by defining 
xmalloc to bird_xmalloc internally.
 2000-03-29 22:57:46 +00:00
Martin Mares a8f944cb6e Wrote real version of unaligned data access functions (needed for BGP). 2000-03-21 15:51:30 +00:00
Martin Mares e68dd11c43 Use do { } while(0) instead of empty DBG if not debugging. 2000-03-12 21:47:25 +00:00
Martin Mares 3cbfcafecd DBG calls debug() if defined(LOCAL_DEBUG) || defined(GLOBAL_DEBUG). 2000-03-07 21:04:14 +00:00
Martin Mares 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.
 2000-03-05 22:48:30 +00:00
Martin Mares 4ebbbd4079 Changed comments regarding hash function. 2000-03-01 12:15:20 +00:00
Martin Mares 14a6c2a705 IP_PREC_INTERNET_CONTROL for IPv6 (see the comment). 2000-03-01 12:03:43 +00:00
Martin Mares ebc793a5f5 No more problems when events get scheduled during event processing. 2000-01-16 17:39:16 +00:00
Martin Mares 12a9d139ee ipv6_compare() accepts non-lvalue arguments as well. This makes filters 
compile with IPv6.
 1999-12-16 13:13:22 +00:00
Martin Mares 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.
 1999-12-06 13:45:56 +00:00
Martin Mares ea32afb765 Added ip_scope_text() for translating of scopes to strings. 1999-11-25 15:34:20 +00:00
Martin Mares 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.
 1999-11-17 12:01:11 +00:00
Martin Mares b93abffae4 Implemented unix-domain sockets. 1999-10-29 12:09:29 +00:00
Martin Mares 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.
 1999-10-29 12:08:49 +00:00
Martin Mares 92af6f309b Simplify handling of free chunks. 1999-10-29 10:08:27 +00:00
Martin Mares 89dc383a8c Changed syntax of ip_class_mask, the old one was stupid. 1999-10-12 07:46:08 +00:00
Martin Mares 507cb9e58b Don't forget to free large blocks. 1999-10-02 10:55:19 +00:00
Martin Mares f651941402 Added a function for generating 32-bit random numbers. 1999-08-17 20:47:40 +00:00
Martin Mares 4f22c98185 Support for IPv6 sockets. How nice one doesn't have to ifdef around 
ten years of API evolution :-)
 1999-08-03 19:36:51 +00:00
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.
 1999-08-03 19:36:06 +00:00
Martin Mares b6628a8c98 Added macros for walking lists backwards. 1999-08-03 19:31:30 +00:00
Martin Mares 5e13ffe6f4 Faster checksum function. 1999-08-03 19:29:57 +00:00
Martin Mares 3e1f30610e Defined IP_PREC_INTERNET_CONTROL and made all (well, both :)) protocols 
use it when creating sockets.
 1999-06-01 13:57:24 +00:00
Martin Mares 139ca21d05 Added sk_send_buffer_empty(). 1999-05-31 13:21:07 +00:00
Ondrej Filip daeb60393d Small bug in ipv4_skip_header. 1999-05-24 17:37:45 +00:00
Martin Mares b23c5e0ff4 Added ip_skip_header() and modified OSPF to use it. 1999-05-14 18:03:09 +00:00
Martin Mares 1a54d44a23 Added packet checksumming code. Watch the comments for an explanation. 1999-05-10 21:37:39 +00:00
Martin Mares 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.
 1999-04-27 16:03:17 +00:00
Martin Mares 2f5d154466 Added ipa_compare as requested. 1999-04-12 20:26:06 +00:00
Martin Mares 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.
 1999-04-12 14:57:46 +00:00
Martin Mares 7976a574b6 ip_pton: Avoid modification of the string we're converting. 1999-04-06 21:31:03 +00:00
Martin Mares 5bc512aa3a Clarify resource dumps and include them in the main debugging dump. 1999-03-29 20:14:33 +00:00
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.
 1999-03-29 19:14:43 +00:00
Martin Mares 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
Martin Mares 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.
 1999-02-11 22:59:06 +00:00
Martin Mares 3b15402fd4 Grrr, forgot to commit the event routines themselves :| 1999-02-11 22:18:36 +00:00
