1 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added `require_reverse_mapping' boolean value to ServerParams
4 structure. If TRUE (not default) the server will require that
5 the connecting host has fully qualified domain name.
7 If the reverse mapping is not required and hostname could not be
8 found the IP address is used as hostname.
10 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
12 * Implemented version string checking to both client and server.
13 The check is incomplete currently due to the abnormal version
14 strings used in development version of SILC.
16 * Changed all command functions in server to use the new
19 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
21 * Changed char *data to unsigned char *data in ID Cache system to
22 support binary data as ID Cache data. Changed code to support
23 binary data in lib/silccore/idcache.c.
25 * Renamed silc_server_packet_relay_command_reply to
26 silc_server_command_reply as it is normal packet receiving
27 function. Rewrote the function to accept command replys for
28 servers and not only for clients.
30 * Mark remote router always as registered server if we are connecting
31 to it. Otherwise, commands sent by the router to us are ignored.
33 * All ID List find routines now returns the ID Cache Entry pointer
36 * WHOIS command works now in router environment, tested with two
37 routers, two servers and two clients.
39 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
40 in router environment (as it is almost equivalent to WHOIS) but
41 hasn't been tested thoroughly. Added new functions:
43 silc_server_command_identify_parse
44 silc_server_command_identify_send_reply
45 silc_server_command_identify_from_client
46 silc_server_command_identify_from_server
48 * Disabled route cache adding because adding two different ID's with
49 same IP replaces the old cache entry thus giving wrong route.
50 The entry->router->connection is always the fastest route anyway
51 so route cache may not be needed. Of course, new routes maybe
52 established after receiving the ID when the entry->router->connection
53 might not be anymore the most optimal.
55 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
57 * Add route cache for received ID for fast routing.
59 * Added silc_server_packet_route to route received packet on router
60 that is not destined to us.
62 * Renamed silc_server_get_route to silc_server_route_get.
64 * Added id_string and id_string_len fields into SilcServer to
65 include encoded ServerID for fast comparing without excess
68 * Cleaned up WHOIS command on server side. Added following static
71 silc_server_command_whois_parse
72 silc_server_command_whois_check
73 silc_server_command_whois_send_reply
74 silc_server_command_whois_from_client
75 silc_server_command_whois_from_server
77 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
78 arguments in command replies. All command functions should be
79 updated to use this macro.
81 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
83 * Minor typo fixes on command reply handling on server.
85 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
87 * Added silc_server_command_add_to_channel internal routine to add
88 the client to the channel after router has created the channel and
89 sent command reply to the server.
91 * Added generic silc_server_send_command to send any command from
94 * Use static buffer with ID rendering instead of duplicating data.
96 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
98 * Fixed a channel user mode bug when joining to a channel server gave
99 everybody channel founder rights, oops.
101 * We mark ourselves as the router of the incoming server connection
102 if we are router ourselves. This way we can check in some packet
103 sending functions whether it is locally connected server. For
104 incoming router connections we put NULL.
106 * For router sending packets locally means now always sending the
107 packet cell wide; to local clients and local servers. For normal
108 server sending packet locally means sending it to only local
111 * Fixed the JOIN command to really work in router environment. If the
112 channel is created it is always created by the router. Router is
113 also responsible of making the initial joining to the channel,
114 sending JOIN notify to the sending server and distributing
115 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
116 does not exist server doesn't do anything else but forward the
117 command to the router which performs everything.
119 * Added silc_server_send_channel_key function to send the Channel Key
122 * Added silc_server_create_channel_key to create new channel key. The
123 channel key is now re-generated everytime someone joins or leaves
124 a channel, as protocol dictates. Note: channel->key_len is the
127 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
129 * Splitted server.[ch] finally. Created now packet_send.[ch] and
130 packet_receive.[ch] to separate packet sending and receiving
131 routines. The server.[ch] now includes everything else including
132 actual packet processing (writing and reading data) and other
135 Renamed silc_server_private_message_send_internal to
136 silc_server_send_private_message. The routine is still though
137 used only to relay private messages as server does not send
138 private messages itself.
140 Renamed silc_server_new_channel to silc_server_create_new_channel
141 and added new function sicl_server_new_channel that handles the
142 incoming New Channel packet. Added also new sending function
143 silc_server_send_new_channel to send New Channel Payload.
145 * Added new function silc_server_notify to process incoming notify
146 packet to the server/router. Server may then relay the notify
147 to clients if needed.
149 * Added new function silc_server_new_channel_user to process incoming
150 New Channel User packet. Router will redistribute the packet and
151 send JOIN notify to its local clients and locally connected servers
152 if needed. Normal server will send JOIN notify to its local client
153 on same channel when received this packet. Added also corresponding
154 sending function silc_server_send_new_channel_user to sent the
157 * Added boolean route argument to send_notif_to_channel and
158 packet_send_to_channel functions to attempt to route the packet
159 if it is TRUE and send only locally if it is FALSE.
161 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
163 * silc_server_replace_id now broadcasts the received replace ID
164 packet if it is not broadcast packet already. The router must
165 broadcast to inform other routers about changed ID.
167 * Added backpointer to server's router into SilcServer context in
168 silcd/server_internal.h.
170 * Fixed silc_server_packet_broadcast to send correct broadcast
173 * The channel key is now distributed to the local client as soon
174 as it is received from the router (in router environment) so that
175 no other packet may be sent for the channel until client has
178 * silc_server_remove_channel_user now broadcasts the received
179 Remove Channel User packet if it is not broadcast packet already.
180 The router must broadcast to inform other routers about removed
183 * Added users field into SilcPacketContext that is a reference count
184 of the context. One can increase the reference count by calling
185 silc_packet_context_dup which is now changed to just increase the
186 reference count instead of duplicating the data. The reference
187 count is decresed by calling silc_packet_context_free that will
188 free the data after the reference count hits zero.
190 For now on the packet context and everything allocated into it
191 (including the raw packet from network) must be freed by calling
192 the new silc_packet_context_free function. Added also new function
193 silc_packet_context_alloc that must be used now to allocate the
194 context. This also means that if a routine is asynchronous from
195 silc_[client/server]_packet_parse_type the packet context must
196 be duplicated by calling silc_packet_context_dup. Otherwise it
197 gets free'd after silc_[client/server]_packet_parse_type returns.
198 Also, one must remember that if packet is duplicated then its
199 reference count must be decresed by calling the free function as
200 many times as it was duplicated.
202 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
203 from both client and server.
205 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
207 * Made joining to a channel working in router environment.
209 * Cleaned up JOIN command on server side and create function
210 silc_server_command_join_channel internal routine to make the
213 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
215 * Changed silc_command_pending list to SilcDList. Also, added
216 `ident' field to SilcServerCommandPending structure to identify
217 the reply and to call correct callback.
219 Added silc_server_command_pending_check function to replace the
220 corresnponding macro. The silc_command_pending list is not
223 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
224 to set identifier to previously allocated Command Payload. It
225 is used to set identifier for command when resending Command
228 * Added silc_command_payload_encode_payload to encode Command
229 Payload buffer from SilcCommandPayload structure.
231 * Added silc_argument_payload_encode_payload to encode Argument
232 payload buffer from SilcArgumentPayload structure.
234 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
236 * Changed WHOIS command to support router connection on server side.
237 The whois request is always sent to router unless the server is
238 standalone server. After server has received the reply from the
239 router will it send the reply to the client.
241 * Added silc_server_packet_broadcast into silcd/server.[ch] to
242 broadcast received broadcast packet. The function is used only
243 by router. The broadcast packet is always sent to the router's
246 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
247 render given ID to printable string, for log files for example.
249 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
251 * Made basic router to router connections working. At least they
252 can now connect to each other but nothing really works the way
253 they are supposed - yet.
255 * Added new initiator token to RouterConnection configuration
256 file in silcd/serverconfig.[ch]. It is used to tell whether we
257 are the initiator to the remote router or whether we'll expect
258 the other end to connect.
260 * Moved registering of listener task to silc_server_init, hence
261 the server starts listenning as soon as it is run, even if it
262 does not have connections to other routers. Let's see how well
265 * Changed default connection retry timeouts for more suitable in
268 * Removed cipher and such arguments from silc_idlist_add_client
269 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
270 Added new function silc_idlist_add_data to add the keys and stuff
273 * Added SilcIDListData structure and added it to SilcClientEntry
274 and SilcServerEntry as their first field in the structure. This
275 way we can explicitly cast the ID entries to the SilcIDListData
276 structure and get common data for the entries. In past, we had
277 to first check what type of connection it is and then cast it to
278 correct ID entry type. Now, we can directly cast the opaque
279 pointer to the SilcIDListData (no matter what ID entry it actually
280 is) and get the data needed.
282 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
284 * Wow, found a bug in scheduler. The scheduler uninitialized itself
285 in some circumstances even if threre were timeout tasks, though not
286 IO tasks, but tasks anyway. Now fixed.
288 * Defined SilcServerConnection structure to hold connection specific
289 stuff about directly connected servers and routers. The definition
290 is currently in silcd/server_internal.h. I thought about having
291 a bit more important role fro this struct but for now it is used
292 only when connecting to other server (or router actually).
294 * Added connecting retry support in server when connecting to
295 router(s). The retry feature implement exponential backoff
296 algorithm. Also, added SilcServerParams structure to hold default
297 parameters for server. For now, it include these retry settings
298 and are hard coded. After server is moded to be as Silc Server
299 Library this structure will be more important.
301 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
303 * Changed client librarys channel->clients table to SilcList and
304 changed code accordingly.
306 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
308 * Changed client's channel table to SilcList and changed code
309 accordingly. Also changed SilcChannelClientEntry to include back-
310 pointer to the channel so that client entry can use that structure
311 as list as well and we have fast cross-reference to the channel.
312 This change dramatically decreased the complexity of channel
313 handling with client entry and vice versa (removed one extra
314 loop when searching for channel entry from many functions).
316 * Changed server->sim from table to SilcDList and changed code
319 * NAMES command can now be used from user interface. It will show
320 the user list on the channel, neatly.
322 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
323 Code now saves realname of the user if it becomes available.
325 * Renamed configure.in to configure.in.pre and made ./prepare
326 script to automatically add correct version string to
327 configure.in which it creates from configure.in.pre.
329 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
331 * NAMES command reply now shows users mode with the nickname when
334 * Moved silc_client_ch[u]mode[_char] functions from
335 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
336 place sucks, they are utility functions and should be in some
339 * Fixed some unsigned int's to unsigned short's. Patch by cras.
341 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
344 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
348 * Added TRQ (efficient deque and list library) into lib/trq. This is
349 a very good list library that is currently used in the SILC. Defined
350 SilcList API over the library because I didn't like the API very
351 much. See lib/trq/silclist.h for the API and examples of how to
352 use the API. Fixed various places in the code to use the new
353 SilcList API. The SilcList is meant for lists that has a structure
354 already defined as a list. It is not suitable to add just some
355 context to the list (in TRQ, the context is the list actually).
357 So, I defined SilcDList that can be used for the purpose where
358 predefined list structure does not exit. This can be used as
359 such list. Now some context just can be added to the SilcDList.
360 Currently this list is not used in the SILC just yet, though there
361 are a lot places where this can replace dynamically allocated
362 tables and I will fix these places, later, to use SilcDList.
363 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
364 and use TRQ internally).
366 Also fixed some annoying warning messages that the original TRQ
367 code generated. Also minor changes to TRQ's Makefile.in.
369 * Added support for querying by Client ID to both WHOIS and
370 IDENTIFY commands into server, as required by the protocol.
372 * Removed method function pointers from SilcBuffer structure. They
373 weren't used to anything and just increased the context size for
374 no good reason. This change also made silc_buffer_alloc and
375 silc_buffer_free functions inline functions.
377 * Disabled command flooding detection support until it's fixed so
378 that it accepts commands in but does not execute them more than once
381 * Added silc_net_localhost(), to return local hostname, into
382 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
383 that must be initialized before calling silc_client_init.
385 * Added new function: silc_server_send_notify_on_channels to send
386 notify messages to all channels client has joined. It is assured
387 that the message is sent only once per client.
389 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
390 lib/silcutil/silcutil.[ch] as silc_format function. The new
391 function is generic and is used by server as well, not only by
392 the logging routines.
394 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
395 the provided version string was not acceptable. Added new function:
396 silc_ske_check_version into lib/silcske/silcske.h. The function
397 must be implemented by the application (client or server) and it
398 does not reside in the SKE library. The function checks the version
399 string remote end sent.
401 * Added back pointers (to opaque context and to SilcSocketConnection)
402 into SilcPacketContext structure into lib/silccore/silcpacket.h.
404 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
405 duplicate packet context structure.
407 * Changed `notify' client operation to send same arguments as client
408 receives from server except for ID's. ID's are mapped to correct
409 ID entry and that is returned. Also, if channel entry is not sent
410 by server but the notify is for channel the channel entry is sent
411 to application (otherwise application doesn't know that it is for
412 channel (library gets it from packet's Destination ID)).
414 * Added silc_client_remove_from_channels into client library to
415 remove a client from all channels it has joined to. Used when
416 received SIGNOFF notify from server. Added also new function
417 silc_client_replace_from_channels to replace old ID entry with
418 new ID entry on all channels. Used when received NICK_CHANGE
421 * Fixed ID Cache list handling in silc_idlist_get_client in
422 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
423 to get (or query) client by ID.
427 * Added connection authentication status message defined by the
428 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
429 support for these into the code in client and server side.
431 * Added generic function silc_client_send_command to send any command
432 with variable argument list. Application should use this function
433 to send commands if the command functions provided by the library
434 does not suite for the application's user interface needs.
436 * Added new `failure' client operation. Application is notified about
437 received failure packet if client is executing a protocol. In this
438 case the protocol's execution has failed.
440 * Added SKE's end notify to send the SKE_SUCCESS notify message that
441 is required by the protocol.
443 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
444 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
447 * Added status flag to SilcSKE object to indicate realtime status
450 * Application receives now exactly same command reply arguments as
451 the library receives from server. However, if ID is received the
452 corresponding ID entry is returned to the application (eg. Client
453 ID is mapped to correct SilcClientEntry entry and that is returned).
454 Changed command_reply client operation due to this change.
456 * Changed all ID's in commands and in command replys as ID Payloads.
457 Change affected both client and server side codes.
459 All ID's sent in SILC network (with execption of ID's in SILC
460 Packet header) are sent in ID Payload to support variable length
463 * Server now notifies nick changes and notifies all clients on
464 the channels about the new nickname (about the new Client ID,
467 * Implemented CMODE command to change channel modes. Supports all
468 channel modes defined by the protocol specs except ban and invite
469 lists. (Also, private channel key mode is supported but support for
470 setting private channel key in client is missing, thus, this mode
471 has no effect on client side (except that server requires that the
472 client uses private channel key and normal channel traffic does not
475 Also, invite mode works per se, but INVITE command does not work
476 yet correctly, so you can set channel as invite only channel but
477 inviting clients to the channel does not work (it is yet to be
478 thought what's the best way to do it).
480 * Added new command SILC_COMMAND_CUMODE to change user mode on the
481 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
482 Implemented CUMODE command to change user's mode on the channel.
483 Supports all modes defined by the protocol specs.
485 * Added NAMES command reply to return users modes on the channel.
487 * Removed unnecessary and slow ciphers from lib/silccrypt.
489 * Set SO_KEEPALIVE option to connection sockets by default.
491 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
493 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
494 redefined the Notify Payload into protocol specs.
496 * Added silc_id_payload_parse_id to get ID directly from raw
499 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
501 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
502 accept searching by Client ID as well.
504 * Added support for LEAVE and SIGNOFF notify types in client library.
506 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
507 to parse ID Payload from raw data.
509 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
511 * Added flags parameter into silc_ske_assemble_security_properties
512 function in lib/silcske/silcske.[ch].
514 * Changed notify client operation to fit better for notify messages
515 sent by server. The notify payload received from server is now
516 passed to the application (after parsing it to SilcNotifyPayload).
517 It is application's responsibility to retrieve the arguments
518 from the payload and show the message the way it wants. The message
519 sent by server is implementation specific.
521 * Changed public keys to comply with the protocol specification.
522 Old public keys are not supported anymore and are not compatible.
524 * Removed nickname from Channel Payload as the latest draft removed
525 it. The client must resolve the nickname from the NAMES command
526 reply received when it joined the channel.
528 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
530 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
532 * Fixed some errors in protocol specification drafts.
534 * Created lib/silccore/silcnotify.c to implement Notify Payload
535 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
536 generic payloads described by protocol specifications. The file
537 includes implementations for ID Payload and Argument Payload.
539 * Changed Command Payload implementation to use the new Argument
540 Payload. Changed command_xxxx_payload to command_payload_xxxx
541 to comply with SILC coding conventions.
543 * Added suppport for Argument Payload handling in Notify Payload
544 implementation as protocol requires it. Added the new support
545 into server and client lib as well.
547 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
549 * Added support for multiple nicknames on same channel. [n] is
550 added locally to the nickname if there are more than one same
551 nicknames on the channel.
553 * Server now sends all nicknames that matched WHOIS request.
554 Client also shows the list received from server.
556 * Added TOPIC command to client side. User can now set and show
557 current topic on channel.
559 * Added MOTD command to client and server. Also, server sends the
560 motd when client connects to the server.
562 * Changed version strings to comply ISO 8601.
564 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
566 * Fixed protocol error handling in client library. It should now
567 cope even if the SKE fails for some reason.
569 * Made new protocol specification drafts for submitting to IETF.
571 * Implemented TOPIC command to server in silcd/command.c.
573 * Added two new notify types into lib/silccore/silcnotify.h:
574 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
575 notify nickname change and topic setting/change on a channel.
577 * API change of command_reply operation in client library. The
578 application gets now the status type received from server as well.
580 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
582 * Removed the function just added to lib/silcutil/silcschedule.[ch].
584 * Cras fixed and optimized the packet handling even further and
585 it should work now. Minor change to the prototype of function
586 silc_packet_receive_process in lib/silccore/silcpacket.[ch].

590 * Added new function into lib/silcutil/silcschedule.[ch]:
591 silc_schedule_with_fd to select() a specified fd. The function
592 returns after timeout expires or data arrives or goes. The
593 function is used by packet routines to wait that all data is
594 received from network.
596 * Fixed data reading from network in lib/silccore/silcpacket.c.
597 The code now assures that all data is read from the fd and then
598 continues packet processing. This was a bug fix since the code
599 used to drop some data in some circumstances.
601 * Added new function into lib/silcclient/client.[ch]:
602 silc_client_start_key_exchange to start key exchange after
603 connection has been established to server. The code internally
604 now uses this funtion but its main purpose was to provide it
605 for applications that perform their own connecting. After
606 application has created a connection it merely calls this
607 function to start the key exchange between client and server.
608 The library takes care of everything else after that.
610 Updated also lib/silcclient/README to explain the usage of
613 * Do not send to application information that connection has
614 been established. Application gets notified it by connect
617 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Applied cras's patch to add silc_schedule_one function. The
620 function runs scheduler once and returns.
622 * Fixed the scheduler after cras messed it up. The timeout
623 handling works now as it's supposed to work.
625 * Added into lib/silccore/ silcnotify.h to include notify
626 message types support. Changed silc_server_send_notify*
627 functions, in server.[ch], to support those new notify types.
628 Added the support for the notify types into client library,
629 as well. Added new notify client operation into ops.h in
632 * Changed silc_server_packet_send_to_channel to send normal
633 packets instead of just channel message packets. The function
634 is now used to send the notify packets to channels. It is not
635 used to send channel message packets anymore, as server never
638 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
639 va_arg()s as it seems to require it nowadays. I guess, if SILC
640 is compiled with older va_arg() the new code should work anyway.
642 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
644 * Splitted core library. Core library (lib/silccore) includes
645 now only SILC protocol specific core (and common) components.
646 Created new utility library (lib/silcutil) that includes more
647 generic purpose stuff. The stuff for util library was taken
648 from the old core library. This was minor and easy split.
650 * Created SILC Client Library (lib/silcclient) that includes
651 implementation of the SILC client without user interface. This
652 was major move from silc/ directory. The code has been changed
653 so that it is transparent towards the user interface. The
654 silc/ directory includes now the same user interface as before
655 and it uses the new client library. Read lib/silcclient/README.
656 Basicly, the client library performs everything else related
657 to SILC except user interface handling. Also, configuration
658 files are considered to be part of user interface and library
659 does not handle them.
661 This change also changed a lot of structures, function naming etc.
662 Most important change was that SilcClientWindow object was
663 renamed to SilcClientConnection in the client library. Created
664 also new file lib/silcclient/ops.h. Also added new files
665 silc/local_command.[ch] and silc/client_ops.[ch].
667 All these changes were made to make it easier for user interface
668 designers to create what ever user interface for the SILC client
671 It is also expected that the server will be moved to lib
672 directory as well and SILC Server Library will be created;
673 sometimes in the future.
675 * Removed Local commands from lib/silccore/silccommand.h as
676 they are application specific and new client library does not
677 handle any of those anymore.
679 * Several functions moved to lib/silcutil/silcutilc.[ch] from
680 old client implementation in silc/.
682 * Added support for callback functions in SILC_LOG_* macros.
683 Application can now set its own callbacks that will be called
684 instead of using the default functions that will always print
685 the debug messages to stderr (or stdout). Also, debugging can
686 now be disabled by setting silc_debug to FALSE and re-enabled by
687 setting it to TRUE. Note, that logging will still work even
688 if debugging is disabled.
690 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
691 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
692 silc_log_reset_debug_callbacks.
694 * To enable debugging in silc client one must give now -d
695 option on command line.
697 * Changed silc_schedule_init to automatically allocate task queues
698 if they are not allocated before calling it.
700 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
702 * Added GMP 3.1 into math library.
704 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
706 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
707 a channel in SILC network. The packet is used by servers and
708 routers to notify other routers that user has left a channel.
709 This little feature was missing until now. Added the feature
710 to protocol specification as well.
712 Added functions: silc_server_send_remove_channel_user and
713 silc_server_remove_channel_user into server.[ch].
715 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
716 lib/silccore/silcpacket.h. However, they are not implemented
719 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
721 * Fixed joining to a channel and sending channel messages
722 between server and router. The channel message sending should
723 now work inside a cell.
725 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
727 * Fixed the private message sending between server and router.
728 The private message sending should now work inside a cell.
730 * Added silc_server_replace_id into server.[ch] to replace
731 existing ID in the SILC network.
733 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
734 and silc_idlist_replace_server_id into idlist.[ch] in server.
736 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
738 * Fixed the server to server connections. Server can again now
739 connect to router. Router to router connections probably does
742 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
744 * Added dynamic protocol registering support. Now protocols can
745 registered and unregistered on the fly. Patch by cras.
747 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
749 * Added lib/contrib directory to hold routines that some platforms
750 don't have but are needed by SILC.
752 * Added getopt.c, getopt1.c and getopt.h from GNU C library
753 into lin/contrib to provide getopt() and getopt_long() for
754 those who don't have it.
756 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
758 * Added AWAY command to client. When away message is set and
759 client receives a private message packet the client automatically
760 replies to the sender with the away message.
762 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
763 bug seemed to be the cause of recent problems when compiling
766 * Added version detection support to SKE protocol specification
767 and added the new changes to the SKE implementation as well.
768 There were other minor changes in the SKE protocol as well.
770 Many changes in lib/silcske/silcske.[ch] and in
771 lib/silcske/payload.[ch].
773 * Added ^U functionality, clear input line. Patch from cras.
775 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
777 * Mainly small bugfixes on core library. Fixed some debugging
778 logging and buffer overflow in silclog.c.
780 * Updated config.sub and config.guess on the distribution tree.
782 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
784 * Added command lagging support in server. Client may execute
785 commands now only once in two seconds.
787 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
789 * Optimized packet reception. MAC computation and checking is now
790 also more optimized. A lot previously duplicated code is now
791 used as generic by both client and server.
793 * Fixed key pair generation in clientutil.c
795 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
797 * Added into lib/silccore/silcbufutil.[ch] new function;
800 * Moved generic packet sending/encryption functions to
801 lib/silccore/silcpacket.[ch] from client and server. Some
802 rewriting of the functions.
804 * Moved all generic packet reception/decryption functions to
805 lib/silccore/silcpacket.[ch] from client and server. The
806 packet processing is now much cleaner in both client and server.
807 These were major changes in both client and server.
809 * Created many common functions in server to do packet sending.
810 Previously code were duplicated a lot, this has been removed
813 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
815 * Rewrote major parts of the ID cache system. Don't know
816 whether it is better now or not but at least the API is more
819 * Major rewrite on ID cache stuff on client because of the ID
820 cache API changes. Added idlist.c to client.
822 * Also major rewrite on ID cache stuff on server as well.
823 Major rewrite of idlist.[ch]. SilcXXXList's are now named
824 SilcXXXEntry's. We won't keep anymore idlist specific pointers
825 in hand, instead they are all put into the ID cache system now.
826 All server_idlist_* routines uses ID cache now instead of
827 traversing its own lists (those lists does not exist anymore).
828 SilcIDList though still exists. Also, SilcXXXEntry's are
831 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
833 * Finally made the SKE implementation compliant to the protocol
834 specification. All mp integers are now binary encoded as
835 opposed being HEX encoded.
837 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
840 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
841 functions: silc_[encode/decode]_pem. Also added function
842 silc_encode_pem_file to PEM encode with newlines ('\n') for
845 * SILC public keys are now encoded either PEM or binary. Same
846 option is for private keys as well. By default private keys
847 are binary encoded and public keys PEM encoded. Silly HEX
848 encoding were removed.
850 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
851 function to create fingerprints.
853 * Fixed a bug in SHA1; does not change the original data anymore.
855 * Partly implemented INFO command on client and server side.
856 Fixed CLEAR command. Changes to SERVER command; show current
857 server(s) when giving command without arguments. Added
858 VERSION command to client.
860 * Added check to server that unregistered connections cannot
861 execute commands (unless it is specificly allowed).
863 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
865 * Fixed screen refresh.
867 * Fixed channel joining bug from client. On some circumstances
868 client tried to join to a channel it had already joined.
870 * Added public key verification process into client's protocol.c.
871 The client now verifies the public key from user and saves
872 it into ~./silc/serverkeys/ directory.
874 Added into: clientutil.[ch]: silc_client_verify_server_key.
876 * Changed SKE protocol's silc_ske_initiator_finish function
877 to accept callback function that verifies the received public
878 key. Removed old silc_ske_verify_public_key function.
880 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
882 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
883 silc_pkcs_private_key[_data]_set.
885 * Made the password and public authentication more cleaner in
888 * Removed historic and obsolete protocol `channel_auth' from
889 both client and server.
891 * Removed wrong way of sending command status messages from
892 server to client in server's command.c. The old way violated
893 protocol specification.
895 Changes to silccore/silccommand.[ch]: removed
896 silc_command_encode_status_payload -> not needed anymore,
897 changed silc_command_encode_payload_va to accept extra
898 argument on variable argument list. The argument type must
899 now be provided to the function. Also, added new function:
900 silc_command_encode_reply_payload_va which is same as
901 normal command_encode_payload_va except command status type
902 is provided as extra argument.
904 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
906 * Added ~./silc directory handling. The directory includes the
907 public and private keys for the client.
909 Added silc_client_check_silc_dir, silc_client_create_identifier
910 and silc_client_load_keys.
912 * Implemented SILC protocol compliant public key. Added public
913 and private key saving to and loading from files.
915 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
916 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
917 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
918 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
919 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
921 Implemented: silc_pkcs_save_[public/private]_key[_data] and
922 silc_pkcs_load_[public/private]_key.
924 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Added silc_server_get_route (route.[ch]) to get connection
927 data for the fastest route for given ID.
929 * Implemented INVITE command on client and server. The command
930 were re-defined in the SILC Protocol Specification and the
931 implementation now complies with the specification.
933 * Implemented PING command on client and server.
935 * Implemented NAMES command on client and server. The server side
936 supports currently only normal server not router server yet.
937 Some changes to NAMES definition in SILC protocol specification.
939 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
941 * Implemented LEAVE command on client and server.
943 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
944 again. This change was made to the protocol as well. Server
945 should not violate the protocol specification anymore.
947 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
949 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
950 was tested. SOCKS4 was not but should work anyway.
