1 Wed May 16 20:02:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Implemented a collision resistant hash table into the
4 lib/silcutil/silchashtable[ch]. See the header and the source
5 for the SilcHashTable API.
7 Tue May 15 22:05:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
9 * Merged dotconf version 1.0.2 into lib/dotconf.
11 Sun May 13 19:32:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
13 * Do not compile anything in lib/silcsim/* if the SIM support
14 is not enabled. The tree should now compile without problems
17 Thu May 10 22:49:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
19 * Compiled the SILC under cygwin. Compiled and tested briefly
20 without problems. More tests needed. The SIMs didn't compile
23 * Added various #ifdef HAVE_* stuff to lib/silccrypt/silrng.c.
25 * Fixed possible crash in silc_get_username in the
26 lib/silcutil/silcutil.c.
28 Tue May 8 09:04:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
30 * Fixed a va_arg in silc/client_ops.c.
32 * Oops, RC5 routines were named AES and caused some problems
33 when not using SIM's. Affected file lib/silccrypt/rc5.c.
35 Sun May 6 13:59:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
37 * Added new SilcIDIP structure into the lib/silccore/id.h and
38 replaced the old `ip' fields from all SILC ID's to that type.
39 This is a step towards IPv6 support.
41 The silc_id_get_len takes now the ID as an extra argument.
42 The silc_id_id2str, silc_id_str2id and silc_id_dup now supports
43 both IPv4 and IPv6 based ID's.
45 The affected files are lib/silccore/id.[ch] and other files
46 around the tree using these routines.
48 * Removed the ID length arguments in server from various
49 silc_server_send_notify_* routines -> they are not needed
52 Sat May 5 13:56:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
54 * Fixed memory leak in silc_encode_pem_file in the file
55 lib/silcutil/silcutil.c.
57 Thu May 3 21:23:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
59 * Check minor version as well in the SKE. Affected files are
60 silcd/protocol.c and lib/silcclient/protocol.c.
62 * Added --identifier option to the server so that an identifier
63 can be when creating the public key for the server. Affected
64 file is silcd/silcd.c.
66 * Fixed minor decoding bug in silc_pkcs_decode_identifier in
67 lib/silccrypt/silcpkcs.c.
69 Wed May 2 20:50:49 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
71 * Register default ciphers and stuff when using -C option with
72 the server. Affected file sildc/silcd.c.
74 * Put back the servers public key filename format, it is better
75 than the new one. For now, the client keys are saved with the
76 new filename format. The affected file silc/client_ops.c.
78 * Implemented the Cipher API for the rest of the ciphers that
79 did not implement it or implemented it the wrong way.
81 Wed May 2 13:31:26 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
83 * Register default ciphers and stuff when using the -S option
84 in the client. Affected file silc/silc.c. Same also when
85 creating new key pair with -C option.
87 Tue May 1 14:18:13 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
89 * Fixed the silc_verify_public_key client operation function to
90 save the public keys differently. The fingerprint is now
91 used as filename and not the hostname. This way also the
92 client keys are saved uniquely and not with hostnames. The
93 affected file is silc/client_ops.c.
95 * Trimmed the silc_hash_fingerprint function to remove extra
96 whitespaces from the end of the fingerprint. The affected
97 file is lib/silccrypt/silchash.c.
101 * Added silc_cipher_register_default function to register all
102 default ciphers. It can be used when configuration files
103 does not exist and the application does not want any specific
104 ciphers in any specific order.
106 The SilcDList is now used as silc_cipher_list dynamically
107 allocated cipher list. Removed the static list all together
108 and now all ciphers must be allocated to the dynamic list.
109 The silc_cipher_alloc routine was changed to check only the
112 All silc_cipher_* routines that used to return int returns
115 The affected files lib/silccrypt/silccrypt.[ch].
117 * The same thing was done to silc_hash_* as for silc_cipher_*
118 routines. Affected files lib/silccrypt/silchash.[ch].
120 * The same thing was done to silc_pkcs_* as for silc_cipher_*
121 routines. Affected files lib/silccrypt/silcpkcs.[ch].
122 Added also silc_pkcs_[un]register[_default] functions.
123 Removed the data_context from the PKCS API.
125 * Added silc_hmac_register_default function to register default
126 hmacs. Affected files lib/silccrypt/silchmac.[ch]. Added also
127 SILC_ALL_HMACS macro that can be used with silc_hmac_unregister
128 to unregister all hmacs at once.
130 * Register the default ciphers, hash functions, PKCSs and HMACs
131 if client's configuration file does not exist. The affected
134 * The client did not load the hash functions from the SIM
135 modules at all. Added support for this. Affected file is
138 * When decoding public key with silc_pkcs_public_key_decode, check
139 the supported algorithm only if PKCS are registered. Affected
140 file lib/silccrypt/silcpkcs.c. The same was done with the
141 silc_pkcs_private_key_decode.
143 * Fixed the SILC List routines to keep the list always in order.
144 It used to change the list's order when traversing the list but
145 not it preserves the order. Affected file lib/trq/silclist.h.
147 Mon Apr 30 17:29:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
149 * Added the client library to use the SilcSocketConnection's
150 reference counter (by silc_socket_dup) to prevent the bug that
151 the socket object may be freed underneath async operation.
153 * The name resolv library checking fixes in the configure.in.pre.
156 * Created new version of the protocol drafts for future
157 development. The -03 drafts are the ones that will be changed
158 in the trunk now and the -02 will remain as they are.
160 * Send list of CUMODE notifys to the router when announcing
161 the channel users to the router. Affected file silcd/server.c.
162 If the router receiving channel founder CUMODE for a channel
163 that already has channel founder it will send CUMODE notify
164 to the sender to remove the channel founder rights from the
165 announced client. Affected file silcd/packet_receive.c.
167 * The CUMODE notify may now use Server ID as well as the entity
168 who changes the mode. Updated protocool specs.
170 * Updated INSTALL and README files.
172 Sun Apr 29 23:17:50 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
174 * New web pages in the http://silc.pspt.fi. The pages was
179 Sun Apr 29 13:33:41 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
181 * Implemented the [DenyConnectin] config section in the server.
182 Added silc_server_config_denied_conn to check whether incoming
183 connection is denied. Affected file silcd/serverconfig.[ch].
185 * Do not check the ports when checking the incoming configuration
186 data if the port is 0, meaning any. Affected file is
187 silcd/serverconfig.c.
189 Fri Apr 20 18:58:43 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
191 * Fixed buffer overflow in silc_string_compare in the file
192 lib/silcutil/silcutil.c.
194 * Fixed double free in silc_server_command_leave in the file
197 Fri Apr 20 14:00:11 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
199 * Fixed the version checking in the server. Affected file is
202 Thu Apr 19 19:52:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
204 * Fixed the configuration data fetching when accepting new
205 connections in the server. Affected file silcd/server.c.
207 Thu Apr 19 11:40:20 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
209 * Added `sender_entry' argument to the function
210 silc_server_packet_relay_to_channel so that we can check
211 whether some destination actually belongs to the same route
212 the sender belongs (ie, we must not resend the packet to the
213 sender). Affected file silcd/packet_send.[ch].
215 * Added `servername' field to the SilcClientEntry in the server
216 to hold the name of the server where client is from. Affected
217 file is silcd/idlist.h.
219 Wed Apr 18 22:19:03 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
221 * Moved the channel message encrypting in the router betwen
222 router connections from silc_server_channel_message to the
223 silc_server_packet_relay_to_channel since we want to check
224 whether we have anybody channel before encrypting anything.
225 Affected files silcd/packet_[receive/send].c.
227 Tue Apr 17 21:18:19 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
229 * Fixed the [AdminConnection] server config section to support
230 multiple entries. Affected file silcd/serverconfig.c.
232 * Added support into the server to check the validity of the
233 incoming connection before executing any KE or authentication
236 * The connection configuration is now saved to the KE and
237 connection auth protocol contexts and not fetched anymore in
238 the protocol. Affected files silcd/server.c, silcd/protocol.[ch].
240 * The local hosts listenning address and port is also resolved
241 now when starting the server. We want to have the socket object
242 to include the real address and port for the listener. Added
243 new function silc_net_check_local_by_sock into the files
244 lib/silcutil/silcnet.[ch].
246 * Fixed a broadcast bug in server -> do not broadcast if we
249 * Fixed a routing bug. Do not route broadcast packets ever.
250 Broadcast packets must be processed always and not routed since
251 they may be destined to some other host than yourself and thus
252 would get routed without no good reason. Affected file is
255 * Added function silc_server_config_is_primary_route to check
256 whether primary router connection has been configured (a router
257 configuration that we are initiating). If there is not, we
258 will assume that there is only two routers in the SILC network
259 and we will use the incoming router connection as our primary
260 route. Affected files silcd/serverconfig.[ch], silcd/server.c.
262 * Changed the order of the broadcasting. Broadcast _after_ the
263 packet has been processed not before. Affected file is
266 * Fixed a [ClientConnection] parsing bug. The port was never
267 parsed correctly thus resulting to port 0. Affected file
268 silcd/serverconfig.c.
270 * Fixed silc_server_send_notify_args -> it ignored the `broadcast'
271 argument and did not set the broadcast packet flag. Affected
272 file silcd/packet_send.c. Fixed same bug in the function
273 silc_server_send_notify as well.
275 * If we receive NEW_ID packet for our own ID in the server, ignore
278 Mon Apr 16 12:10:33 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
282 * Removed the nickname from the Private Message Payload.
283 Updated the code and the protocol specs.
285 * Updated protocol specs for submitting to the IETF.
287 * Tweaked the Random Number Generator a bit. Affected file
288 lib/silccrypt/silcrng.c. Exported a new function
289 silc_rng_[global]_add_noise which can be used to add more
292 Sat Apr 14 16:21:32 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
294 * Do not parse packets with different timeout when protocol
295 is active -> may cause problem with rekey. Affected file
298 * When server receives signoff notify it must not create
299 new channel key if the client is on any channels since the
300 sender of the signoff notify will create it.
302 Fri Apr 13 17:12:46 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
304 * Added printing of error messages during SKE protocol from the
305 failure packet sent by server during SKE. Affected file
308 * Removed the client's failure_callback handling with timeout
309 and handle it immediately when received.
311 * The SKE library returned wrong type in SUCCESS and FAILURE
312 packets. They must be 32 bit MSB not 16 bit MSB.
314 Fri Apr 13 00:09:08 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
316 * Ok, rewrote the logic of the re-key and now it seems to work.
317 I tested it on high traffic with frequent re-keys without
318 problems. Added hmac_receive (and renamed hmac to hmac_send)
319 in SilcClientConnection in lib/silcclient/client.h and
320 in SilcIDListData in silcd/idlist.h. Also, removed the
321 SilcPacketParserContext's cipher and hmac fields as they are
322 not needed anymore and actually caused some problems when
323 the ciphers and hmac's changed underneath the packet parser.
325 Thu Apr 12 14:42:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
327 * If re-key protocol is active then process the incoming packets
328 synchronously since we must assure that icoming packets encrypted
329 with the old key is processed before the new keys is set to
330 use. This is true other packets than for REKEY packets.
331 Affected file silcd/server.c. The same was done to client library
332 as well, affected file lib/silcclient/client.c.
334 Thu Apr 12 12:01:52 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
336 * Fixed bug in client and server to accept the force send if
337 the packet is send from silc_[server/client]_packet_process
338 function. Otherwise the packets are never delivered, oops.
340 Wed Apr 11 22:10:15 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
342 * Disable force sending of packets when REKEY protocol is active.
343 We must assure that no packet is sent directly when rekey is
344 performed. All packets must be sent through packet queue.
345 Added macro SILC_SERVER_IS_REKEY to silcd/server.h and
346 SILC_CLIENT_IS_REKEY to lib/silcclient/client.h. Affected
347 function is silc_[server/client]_packet_send_real to check
350 * Replaced the SIM paths from example config files to
351 /usr/local/modules. Also, make install creates now
352 /usr/local/silc/logs directory to hold all the SILC server
355 Wed Apr 11 16:59:59 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
357 * Made the configure.in.pre work on Solaris. Patch by salo.

360 CBC mode macros into lib/silccrypt/ciphers_def.h.
362 Tue Apr 10 20:32:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
364 * Fixed the make install.
366 Tue Apr 10 16:20:34 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
368 * When MAC computation fails the silc_packet_decrypt returned 0
369 even though it was supposed to return -1. Fixed this. The
370 affected file is lib/silccore/silcpacket.c.
372 * Do not replace the config files in /etc/silc (in make install)
373 if they already exist. Affected file ./Makefile.am.
375 * Do not send re-key packets immediately but through packet queue.
376 Affected file silcd/protocol.c and lib/silcclient/protocol.c.
378 * Changed silc_net_check_host_by_sock to return FALSE if the
379 IP/DNS could not be resolved. Though, it returns the IP address
380 now even if it could not resolve it (but returns also FALSE).
381 Affected file lib/silcutil/silcnet.[ch].
383 Mon Apr 9 21:54:44 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
385 * Added silc_pkcs_decode_identifier to decode the public key's
386 identifier. Affected file lib/silccrypt/silpkcs.[ch].
387 Added also silc_pkcs_free_identifier. Added also new context
388 SilcPublicKeyIdentifier.
390 * Added -S option to the silc client. It is used to dump the
391 contents of the specified public key file.
393 * Changed the PKCS api to return the public key length when
394 setting the public key.
396 * Fixed a fatal bug in the public and private key file loading.
397 Affected file lib/silccrypt/silcpkcs.c.
399 * Execute the packet parsing for client with zero (0) timeout
400 if the protocol is active. Affected file silcd/server.c.

404 * Made the key generation options to the silcd program. Added
405 -C option, equivalent to client's option.
407 * Added new [ServerKeys] config section to the server. It
408 configures the server's public and private key.
410 * Defined generic Public Key Payload into the protocol
411 specification to send specific type of public keys and
414 * Defined new command SILC_COMMAND_GETKEY to fetch a client's
415 public key or certificate.
417 * Implemented the GETKEY command to the server and to the
418 client library and on user interface.
420 Sun Apr 8 01:37:21 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>

459 for private messages, just use it. Affected file is
460 silc/local_command.c.
462 * Added `send_enc_key' and `enc_key_len' fields to the
463 SilcIDListData structure since they are needed in the re-key
464 phase. Affected file is silcd/idlist.[ch].
466 * Implemented the simple re-key protocol into the server.
467 Affected files silcd/server.c and silcd/protocol.[ch]. The

483 * Defined uint8, int8, uint16, int16, uint32, int32, uint64 and
484 int64 of at least the xintXX size. If void * is less that 4
485 bytes uint32 * will be used. Defined bool as boolean.
487 * Changed _ALL_ unsigned long and unsigned int to uint32,
488 unsgined short to uint16 in the source tree.
490 * Fixed a fatal bug in silc_server_remove_clients_by_server. Do

516 authentication protocol in the client library. Affected file
517 lib/silcclient/protocol.c.
519 * Changed the server's silc_idlist_get_clients_by_* interface
520 to support already allocated array so that new entries may be
521 added to pre-allocated array. Affected file silcd/idlist.[ch].
522 This fixes some bugs with WHOIS, WHOWAS and IDENTIFY commands
525 * All command reply functions in the server now calls the
526 pending command callback even if error occured. This way the
527 error will be delivered to the client as well. Affected files
528 silcd/command.c and silcd/command_reply.c.
530 * Fixed INFO command to return local server's info if no server
531 was provided. Affected file lib/silcclient/command.c.

572 simple buffer unformatting to do the parsing. A lot faster
575 Added new Mutual Authentication flag (SILC_SKE_SP_FLAG_MUTUAL)
576 to the SKE that is used to indicate whether both of the SKE
577 parties should perform authentication. By default only the
578 responder performs authentication. By setting this flag also
579 the initiator must do authentication. By default it is unset
580 since in normal SKE case, client to server connection, only
581 the responder should do authentication. When doing SKE between
582 two clients both should perform authentication. Updated the
583 code and the protocol specs.
585 * A little fix to IDENTIFY command in the server. Search the
586 client first by hash not nickname. Affected file is
589 * Fixed the silc_client_close_connection to support closing
590 the client to client connections wihtout deleting too much
591 data. Affected file lib/silcclient/client.c.
593 * Fixed a fatal bug in server and client; if KE1 or KE2 packets
594 are received if protocol used to be active but is not anymore
595 the application would crash due to NULL pointer dereference.
596 Affected files silcd/server.c and lib/silcclient/client.c.
598 * Added `hash' field to the SilcClientConnection to include
599 the hash function negotiated in the SKE protocol.
601 * Added new channel mode SILC_CMODE_FOUNDER_AUTH that is used
602 to set the channel founder authentication data. A client can
603 claim the founder rights later by providing the authentication
604 data to the CUMODE command using SILC_CUMODE_FOUNDER mode.
605 This way the channel founder can regain the channel founder
606 privileges even it is left the channel. This works only on
607 local server and the client must be connected to the same
608 server to be able to regain the founder rights. Updated the
609 protocol specs accordingly.
611 Added support to the CMODE command in the client to set the
612 founder auth data. Read the README to see how to set it.
614 Added support to the CUMODE command to claim the founder
615 rights. Read the README to see how to do it.
617 Added support for the founder authentication to the Channel
618 Entry in the server. Affected file silcd/idlist.h.
620 Added support for the SILC_CMODE_FOUNDER_AUTH mode in the
621 server's CMODE command. Affected file silcd/command.c.
623 * Added the following new functions into lib/silccore/silcauth.[ch]:
624 silc_auth_get_method and silc_auth_get_data.
626 * The server now saves the remote hosts public key to the
627 SilcIDListData pointer. Affected file silcd/protocol.c.
629 * The normal server now does not remove the channel entry from
630 the cache if the founder authentication data is set. It used
631 to remove it if the founder was the last one on the channel on
632 the server and left the channel. The auth data is saved and
633 if the channel is re-joined later the old entry is used with
634 the old auth data. Affected files silcd/command_reply.c and
637 * Removed the `pkcs' field from the SilcIDListData structure
638 in the server; it is not used. Affected file silcd/idlist.h.
640 Sat Mar 31 15:38:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
642 * Fixed packet processing on slow links. Partial packets were
643 never re-processed because the incoming data buffer was cleared
644 by the application. Application must not directly clear the
645 sock->inbuf, the packet processing routines handle it. Fixed
646 this in client library and in server.
648 Fri Mar 30 16:35:27 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
650 * Fixed the WHOIS and IDENTIFY send reply function to really
651 check whether to send list or just one entry. Affected file
654 * Cleaned up the LEAVE command's channel key distribution. The
655 affected file silcd/command.c.
657 * Changed CMODE_CHANGE's <Client ID> to <ID Payload> as server
658 can enforce the channel mode as well. In that case the ID
659 includes the ID of the server. The code now enforces the
660 mode change if the router have different mode than the server.
662 * The notify client operation with CMODE_CHANGE notify can now
663 return NULL client_entry pointer if the CMODE was not changed
664 by client. Application must check for this.
666 * Added <Server ID> argument to INFO command to support server
667 info fetching by Server ID.
669 * Added silc_server_announce_get_channel_users to get assembled
670 packets of channel users of the specified channel. Affected
671 file silcd/server.[ch].
673 * Fixed bug in CHANNEL_CHANGE notify in the server. The new ID
674 was freed underneath the ID Cache.
676 * Re-announce clients when the server received CHANNEL_CHANGE
677 notify from the router. Affected file silcd/packet_send.c.
679 Thu Mar 29 19:10:28 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
681 * Fixed a fatal bug when client does /join 1 2 3 4 5 6 the server
682 crashed since it did not handle the fact that there is no cipher
683 called "3" and didn't check the error condition. Now fixed.
685 * Added SILC_MESSAGE_FLAG_REQUEST message flag as generic request
686 flag. It can be used to send message requests.
688 Thu Mar 29 12:26:25 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
690 * Implemented the RESTART command in the client.
692 * Added SILC_MESSAGE_FLAG_NOTICE message flag for informational
693 notice type messages. Added notice printing to the user
696 * The channel keys are not re-generated if the channel's mode
697 is PRIVKEY, ie private key on the channel exists. Affected
698 files silcd/server.c and silcd/command.c.
700 * Fixed a little bug in channel message delivery when channel
701 private keys are set in the server. Affected file is
704 * Changed the setting on channel->on_channel = TRUE from the
705 silc_client_save_channel_key to the JOIN command reply. The
706 key payload is not received if the private channel key is set.
707 Affected file lib/silcclient/command_reply.c and the
708 lib/silcclient/client_channel.c.
710 * When the CMODE_CHANGE notify is sent and the channel private
711 key mode is removed the channel key must be re-generated in
712 other cells as well. Added this support for the router in the
713 silcd/packet_receive.c.
715 * Added new local command NOTICE to send notice message on
716 channel. Affected file silc/local_command.[ch].
718 Wed Mar 28 23:55:54 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
720 * Added new local command ME to the client. It is used to send
721 message to a channel with SILC_MESSAGE_FLAG_ACTION to indicate
722 some action. Affected file silc/local_command.[ch].
724 * Changed channel_message and private_message client operations
725 to deliver the message flags to the application. Added also
726 the `flags' arguments to the silc_client_send_channel_message
727 and silc_client_send_private_message functions. Affected file
730 Wed Mar 28 20:50:47 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
732 * Redefined the Private Message Payload to support private message
733 keys and to support the new private message flags. Updated
734 the protocol specs. Flags makes it possible to have for example
737 * Added new type SilcPrivateMessagePayload and defined an API
738 for it in the lib/silcclient/silcprivate.[ch].
740 * Tested private message private keys successfully. Tested the
741 private message key set, unset and list commands with the new
744 * Redefined the Channel Message Payload to include the channel
745 message flags (equal with private message flags) to support
746 for example CTCP style messages.
748 * Defined some of the message (for channel and private message)
749 flags. Updated the protocol specs and added the flags to the
750 lib/silccore/silcchannel.h. The type is SilcMessageFlags.
752 Wed Mar 28 15:52:36 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
754 * Added SilcKeyAgreementStatus type to the key agreement routines
755 to indicate the current status and error if one occured.
756 The status types are defined in the lib/silcclient/silcapi.h.
758 * Added new local command KEY that is used to set and unset private
759 keys for channels, set and unset private keys for private messages
760 with remote clients and to send key agreement requests and
761 negotiate the key agreement protocol with remote client. The
762 key agreement is supported only to negotiate private message keys,
763 it currently cannot be used to negotiate private keys for channels,
764 as it is not convenient for that purpose.
766 * Fixed a minor pending callback setting bug in the function
767 silc_client_get_client_by_id_resolve, now the function works.
768 Affected file lib/silcclient/idlist.c.
770 * Added function silc_net_get_local_port to get local bound
771 port by socket. Added to lib/silcutil/silcnet.[ch].
773 * Added `sockets' and `sockets_count' fields to the SilcClient
774 object. They hold the sockets of the listenning sockets in
775 the client. Listenning sockets may be for example the key
776 agreement server. Affected file lib/silcclient/client.[ch].
777 Added functions the silc_client_add_socket and the
778 silc_client_del_socket. They are exported to the application
781 * Added ~./silc/clientkeys to support other client's public keys.
783 * Renamed verify_server_key client operation to verify_public_key
784 and added one argument to indicate the type of the connection
785 (server, client etc.).
787 Tue Mar 27 22:22:38 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
789 * Added silc_server_connection_auth_request to handle the
790 incoming CONNECTION_AUTH_REQUEST packet. Affected file is
791 silcd/packet_receive.[ch].
793 * Added silc_server_send_connection_auth_request into the
794 silcd/packet_send.c to send the connection auth request packet.
796 * Cleaned up the silcd/protocol.c a bit and fixed some memory
799 * Fixed the public key authentication in responder side in the
800 server. The `auth_data' pointer includes the SilcPublicKey
801 not the path to the public key. Affected file silcd/protocol.c.
803 * Implemented the public key authentication in the initiator side
804 in the server. Affected file silcd/protocol.c.
806 * Removed the [RedirectClient] config section from the server
807 configuration. Is not needed and I don't want to implement it.
809 Tue Mar 27 12:49:56 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
811 * Cleaned up the CMODE command in the server. It now works
812 correctly and supports all the modes defined in the protocol.
813 Affected file is silcd/command.c.
815 * Added `hmac_name' field to the SilcChannelEntry in the server
816 to hold the default HMAC of the channel. It can be set when
817 creating the channel (with JOIN command). Affected files
820 * Added <cipher> and <hmac> argument to the CMODE_CHANGE notify
821 type to indicate the change of the current cipher and hmac
822 on the channel. Client can safely ignore the <cipher> argument
823 (if it chooses to do so) since the CHANNEL_KEY packet will
824 force the channel key change anyway. The <hmac> argument is
825 important since the client is responsible of setting the new
826 HMAC and the hmac key into use.
828 * Fixed the CMODE command in the client library as well.
830 * Tested CMODE command in router environment successfully.
832 Mon Mar 26 14:39:48 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
834 * Show the version of the remote client (or server) when connecting
835 to the server. It is logged to the log file. Affected file
838 * Fixed the KILLED notify handling in the client library. The
839 client must be removed from all channels when receiving the
842 Also, do not remove the client entry when giving the KILL
843 command but when the KILLED notify is received.
845 * Removed silc_idlist_find_client_by_nickname from the server.
846 Not needed anymore. Affected files silcd/idlist.[ch].
848 * Implemented the CHANNEL_CHANGE notify type handling to the
849 server. Affected file silcd/server.c.
853 Mon Mar 26 12:11:14 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
855 * Added silc_server_send_notify_invite to send the INVITE
856 notify between routers.
858 * Implemented the INVITE command correctly to the server.
860 * Implemented the INVITE notify type handling in the server.
862 * Implemented the INVITE command to the client library and on the
865 Sun Mar 25 20:27:09 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
867 * Added function silc_server_get_client_resolve to find the
868 client entry by ID from all ID lists and then resolve it
869 (using WHOIS) if it cannot be found. Affected file is
872 Sun Mar 25 13:52:51 EEST 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
874 * Implemented the BAN command to the client library.
876 * The JOIN command in the server now checks the invite list
879 * Changed the silc_command_reply_payload_encode_va and the
880 silc_command_payload_encode_va to support that if argument is
881 NULL it ignores and checks the next argument. Affected file
882 lib/silccore/silccommand.c.
884 * Added silc_server_send_notify_ban to send the BAN notify
885 type between routers.
887 * Chaned the silc_notify_payload_encode to support that if
888 argument is NULL it ignores and checks the next argument.
889 Affected file lib/silccore/silcnotify.c.
891 * Tested ban lists in router environment successfully.
893 Sat Mar 24 14:47:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
895 * Implemented BAN command to the server, in silcd/command.[ch].
897 * Removed the BAN and INVITE_LIST modes from the CMODE command
900 * Added function silc_string_match to regex match two strings.
901 Affected files lib/silcutil/silcutil.[ch].
903 Fri Mar 23 22:02:40 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
905 * Redefined parts of the SilcChannelEntry in the server to support
906 the new ban and invite lists.
908 Fri Mar 23 16:25:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
910 * Redefined the INVITE command. The same command can be used to
911 invite individuals to the channel but also to manage the invite
912 list of the channel (to add to and remove from the invite list).
913 Updated the protocol specs.
915 * Added new command SILC_COMMAND_BAN that can be used to manage
916 the ban list of the channel. Updated the protocol specs.
918 * Removed the channel modes: the SILC_CMODE_BAN and the
919 SILC_CMODE_INVITE_LIST as they were a bit kludge to be included
920 in the CMODE command. The equivalent features are now available
921 using INVITE and BAN commands. Updated the protocol specs.
923 * Added new SILC_NOTIFY_TYPE_BAN notify type to notify routers
924 in the network about change in the current ban list. The notify
925 type is not used by the client.
927 * Redefined parts of the SILC_NOTIFY_TYPE_INVITE command to
928 support the invite lists.
930 Thu Mar 22 22:52:23 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
932 * Added new function silc_string_regexify that converts string
933 including wildcard characters into regex string that can
934 be used by the GNU regex library. Added into the file
935 lib/silcutil/silcutil.[ch].
937 Added silc_string_regex_combine to combine to regex strings
938 into one so that they can be used as one regex string by
939 the GNU regex library. Added into the file
940 lib/silcutil/silcutil.[ch].
942 Added silc_string_regex_match to match two strings. It returns
943 TRUE if the strings match. Added into lib/silcutil/silcutil.[ch].
945 Thu Mar 22 15:29:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
947 * Imported GNU regex to the soruce tree into lib/contrib.
948 Fixed some compiler warning from the regex.c.
950 Wed Mar 21 15:27:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
952 * Fixed MOTD command in the server to work in router environment.
954 * Fixed the MOTD command in the client library to support
955 the server argument in the command.
957 * Added `nickname_len' argument to the silc_idlist_add_client
958 in the server, as the `nickname' argument may be binary data
961 * Added silc_idlist_get_channels to return all channels from
964 * Implemented LIST command to the server. Affected file is
967 * Implemented the LIST command to the client library and on the
970 * Added [<user count>] argument to the LIST command reply.
971 With private channels the user count is not shown.
973 * Updated TODO and README.
975 Tue Mar 20 21:05:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
977 * The client entry's data.registered must be TRUE even with
978 global client entry on global client list. The data.registered
979 is used to check whether the client is anymore in the network,
980 for example with WHOWAS command so it must be valid.
982 * Fixed the WHOWAS command in the server. It now actually works
983 in router environment. Added function into silcd/command_reply.c
984 silc_server_command_reply_whowas_save.
986 * Added silc_idlist_purge function to the silcd/idlist.c
987 to periodically purge the ID Cache.
989 * Fixed INFO command in the server. It works now in router
990 environment. Added <server name> argument to the INFO command
991 reply. Updated the protocol specs.
993 * Fixed minor bug in silc_idcache_purge to not purge if the
994 expire value is zero.
996 * Fixed various bugs in WHOIS and IDENTIFY command handling as
997 they were buggy because of the WHOWAS information.
999 * Fixed local command MSG to handle the async resolving of
1000 the remote client properly. It used to fail the first MSG.
1001 Affected file silc/local_command.c.
1003 * Added `data_len' field to SilcIDCache context.
1005 Tue Mar 20 16:29:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1007 * Update TODO. Todo in commands in the server.
1009 Tue Mar 20 15:45:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1011 * Added new notify type SILC_NOTIFY_TYPE_UMODE_CHANGE that is
1012 used by routers as broadcast packet to inform other routers
1013 about the changed user mode.
1015 Implemented the notify handling in the server. Affected file is
1016 silcd/packet_receive.c. Added the function
1017 silc_server_send_notify_umode to the silcd/packet_send.[ch].
1019 * Added new generic Channel Payload and deprecated the New Channel
1020 Payload. The New Channel Payload is now the generic Channel
1023 * Added new argument `mode' to the silc_server_send_new_channel
1024 as it is required in the Channel Payload now.
1026 * Renamed the SilcChannelPayload to SilcChannelMessagePayload
1027 and created a new and real SilChannelPayload to represent the
1028 new generic Channel Payload. Implemented the encode/decode
1029 for Channel Payload. Affected file lib/silccore/silcchannel.[ch].
1031 * Added silc_server_get_client_channel_list to return the list
1032 of channels the client has joined for WHOIS command reply.
1033 Affected file silcd/server.[ch].
1035 * Implemented the channel list sending in the WHOIS command reply
1036 in server and in the client.
1038 Implemented the channel list displaying on the user interface
1039 as well. Affected file silc/client_ops.c.
1041 * Added silc_channel_payload_parse_list to parse list of Channel
1042 Payloads. It returns SilcDList list of SilcChannelPayloads.
1043 Client for example can use this function to parse the list of
1044 channels it receives in the WHOIS command reply. The caller
1045 must free the list by calling silc_channel_payload_list_free.
1046 Affected files lib/silccore/silcchannel.[ch].
1048 Mon Mar 19 21:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1050 * Added one new argument <user mode> to the WHOIS command reply
1051 to return the mode of the user in SILC. Updated the protocol
1054 Implemented it to the server and client.
1056 Mon Mar 19 18:43:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1058 * Fixed the mode printing on the user interface on joining.
1059 Affected file silc/client_ops.c.
1061 * Implemented the UMODE command and user modes in general to the
1062 client library and to the user interface.
1064 * Implemented the UMODE command to the server.
1066 * The server now sends UNKNOWN_COMMAND error status if client sends
1067 unknown command. Affected file silcd/command.c.
1069 * All server commands now handle the command identifier the right
1070 way when sending the command reply to the client. The client can
1071 use to identify the command replies with the identifier.
1073 Mon Mar 19 16:13:07 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1075 * Added silc_server_get_client_route to resolve the route to
1076 the client indicated by the client ID. Affected file is
1079 * Added silc_server_relay_packet as general function to relay
1080 packet to arbitrary destination. This deprecates functions
1081 like _send_private_message_key, _relay_notify etc. Affected
1082 file is silcd/packet_send.[ch].
1084 Removed silc_server_send_key_agreement,
1085 silc_server_send_private_message_key and
1086 silc_server_packet_relay_notify functions from the file
1087 silcd/packet_send.[ch].
1091 * Implemented the SILC_NOTIFY_TYPE_KILLED notify handling in the
1092 server. Affected file silcd/packet_receive.[ch].
1094 * Implemented the KILL command to the client. Implemented the
1095 SILC_NOTIFY_TYPE_KILLED notify handling in the client library.
1096 Affected files lib/silcclient/command[_reply].c and
1097 lib/silcclient/client_notify.c. Implemented the KILL notify
1098 printing in the user inteface.
1100 * Fixed a lot silc_parse_nick memory leaks from the client
1101 library in the file lib/silcclient/command.c.
1103 * Changed the silc_server_send_notify_on_channels's `sender'
1104 argument from SilcSocketConnection to SilcClientEntry to
1105 check the sender as entry and not as connection object and not
1106 to send to the client provided as argument. The affected file
1107 is silcd/packet_send.[ch].
1109 * The notify packets that are destined directly to the client used
1110 to not to be processed by the server. Now changed that and the
1111 server processes all notify packets. After relaying the packet
1112 to the client the notify packet is processed in the server.
1114 * The silc_server_free_client_data now checks whether there is
1115 pending outgoing traffic for the client and purges the data to
1116 the network before removing the client entry.
1118 Sun Mar 18 21:02:47 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1120 * Added SILC_NOTIFY_TYPE_KILLED notify type. It is sent when
1121 an client is killed from the SILC Network. Updated the protocol
1124 Added new function silc_server_send_notify_killed to the
1125 silcd/packet_send.[ch].
1127 * Added function silc_server_packet_relay_notify to relay notify
1128 packets that are destined directly to a client. In this case
1129 the server does not process the notify packets but merely relays
1130 it to the client. Affected file silcd/packet_send.[ch].
1132 Added also silc_server_packet_process_relay_notify to check
1133 whereto relay the notify. Affected file is
1134 silcd/packet_receive.[ch].
1136 * Implemented the KILL command to the server.
1140 * Added the backup schema desgined last fall to the protocol
1141 specs for everyone to see. The specification is in the
1142 *-spec-xx.txt draft and the packet type definitions for the
1143 backup routers is in *-pp-xx.txt draft. Thusly, added also
1144 new packet type SILC_PACKET_CELL_ROUTERS.
1146 * A big security problem in the implementation discovered. The
1147 signoff of an client did not cause new channel key generation
1148 which it of course should've done. The channel keys must be
1149 always re-generated when client leaves (or signoffs) the channel.
1150 The silc_server_remove_from_channels funtion now handles
1151 the channel key re-generation.
1153 * Added `sender' argument to the silc_server_send_notify_on_channels
1154 to not to send the client provided as argument. Affected file
1155 silcd/packet_send.[ch].
1157 Fri Mar 16 15:52:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1159 * Implemented OPER and SILCOPER commands into the server and
1162 * Added silc_auth_verify and silc_auth_verify_data to verify
1163 the authentication directly from the authentication payload.
1164 It supports verifying both passphrase and public key based
1165 authentication. Affected file lib/silccore/silcauth.[ch].
1167 * Added `hash' field to the SilcIDListData structure. It is the
1168 hash negotiated in the SKE protocol. Affected file is
1171 * Slight redesigning of the SilcAuthPayload handling routines.
1172 Do not send SilcPKCS but SilcPublicKey as argument.
1174 * Implemented the public key authentication support to the
1175 serverconfig. The public key is loaded from the provided path
1176 and saved as authentication data to void * pointer. Thus,
1177 changed the unsigned char *auth_data to void *auth_data;
1179 * Fixed SHUTDOWN command to send the reply before the server
1180 is shutdown. :) Affected file silcd/command.c.
1182 * Fixed fatal bug in CONNECT command. The hostname was invalid
1183 memory and server crashed. Affected file silcd/command.c.
1185 * Fixed fatal bug in CLOSE command. The server_entry became
1186 invalid but was referenced later in the command. Affected file
1189 Thu Mar 15 12:46:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1191 * Fixed fatal bug in failure packet handling. Server ignored
1192 the failure and thus crashed when it came.
1196 Wed Mar 14 20:37:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1198 * Added new SILC_CF_LAG_STRICT command flag that strictly forces
1199 that the command may be executed only once in (about) 2 seconds.
1200 The old SILC_CF_LAG flag is same but allows command bursts up
1201 to five before limiting.
1203 Added the support for CF_LAG and CF_LAG_STRICT flags to the
1204 server code. Various commands now includes the CF_LAG_STRICT
1205 flag to disallow any kind of miss-use of the command.
1207 * Fixed the silc_buffer_unformat to not to allocate any data
1208 if the length of the data is zero. It used to allocate the
1209 length + 1. Affected file lib/silcutil/silcbuffmt.c.
1211 Wed Mar 14 16:10:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1213 * Changed the format of AdminConnection configuration section
1214 in the server. Added username of the admin to the format.
1215 Affected files silcd/serverconfig.[ch].
1217 Added silc_server_config_find_admin into silcd/serverconfig.[ch]
1218 to return admin configuration data by host, username and/or
1221 Wed Mar 14 13:18:16 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1223 * Implemented WHOWAS command to the server. Added the functions:
1225 silc_server_command_whowas_parse,
1226 silc_server_command_whowas_send_reply,
1227 silc_server_command_whowas_from_client and
1228 silc_server_command_whowas_from_server
1230 * Added <Client ID> argument to the WHOWAS command reply. Updated
1231 the protocol specs accordingly.
1233 * Implemented WHOWAS command and command_reply to the client
1236 Implemented the WHOWAS printing on the user interface.
1238 Tue Mar 13 22:17:34 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1240 * Added new argument to the WHOWAS command reply, the real name.
1241 It is an optional argument. Updated the protocol specs.
1243 * Added SilcIDCacheDestructor callback that is registered when
1244 the SilcIDCache is allocated. The callback is called when
1245 an cache entry in the ID Cache expires, or is purged from the
1246 cache. Added into lib/silccore/idcache.[ch].
1248 Added silc_idlist_client_destructor to the silcd/idlist.[ch]
1249 to destruct the client entries when the cache entry expires.
1250 Other ID Cache's in server and in the client library ignores
1253 * If the ID Cache entry's `expire' field is zero then the entry
1254 never expires. Added boolean `expire' argument to the
1255 silc_idcache_add function in the lib/silccore/idcache.[ch].
1256 If it is TRUE the default expiry value is used.
1258 * Added silc_server_free_client_data_timeout that is registered
1259 when client disconnects. By default for 5 minutes we preserve
1260 the client entry for history - for WHOWAS command.
1262 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1264 * Added support to the server to enforce that commands are not
1265 executed more than once in 2 seconds. If server receives
1266 commands from client more frequently, timeout is registered
1267 to process the commands. Affected file silcd/command.c.
1268 Added new function silc_server_command_process_timeout.
1270 * Changed NICK_NOTIFY handling in client library to check that
1271 if the client's nickname was changed, so there is no need to
1272 resolve anything from the server.
1274 * Removed error printing from the WHOIS and IDENTIFY commands.
1275 If error occurs then it is ignored silently in the client library.
1276 The application, however, may map the received error to
1277 human readable error string. The application currently maps
1278 the NO_SUCH_NICKNAME error to string.
1280 * Made the command status message public to the application. Moved
1281 them from lib/silcclient/command_reply.c to
1282 lib/silcclient/command_reply.h. The application can map the
1283 received command status to the string with the
1284 silc_client_command_status_message function.
1286 * Added check to the server to check that client's ID is same
1287 as the Source ID in the packet the client sent. They must
1290 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1292 * Added dist-bzip hook to the Makefile.am to make bzip2
1293 compressed distributions.
1295 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1297 * Server now enforces the maximum length for the nickname and
1298 the channel as protocol specification dictates. 128 bytes for
1299 nickname and 256 bytes for channel name.
1301 * Moved the WHOIS printing to the application. The client libary
1302 does not print out the WHOIS information anymore, the application
1303 must do it. Renamed silc_client_command_reply_whois_print to
1304 the silc_client_command_reply_whois_save.
1306 The client's idle time is also sent to the application now, and
1307 the idle is shown on screen.
1309 * Added silc_client_command_reply_identify_save to save the
1310 received IDENTIFY entries.
1312 * Do not check for channel private keys in message sending and
1313 reception if the channel does not have the PRIVKEY mode set.
1314 Affected file lib/silclient/client_channel.c.
1316 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1318 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
1319 just surfaced after chaning the JOIN procedure.
1321 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1323 * Added silc_client_get_clients_by_list to get client entries
1324 from Client ID list, that is returned for example by JOIN
1325 and USERS command replies. The application should use this
1326 function for example when JOIN command reply is received to
1327 resolve the clients already on the channel (library does not
1328 do that anymore as USERS command reply is not used in the JOIN
1329 procedure anymore). Affected files lib/silcclient/silcapi.h and
1330 lib/silcclient/idlist.c.
1332 * JOIN command reply and USERS command reply returns now SilcBuffer
1333 pointers instead of unsigned char pointers when returning
1334 the client list and mode list.
1336 * Added <Client ID> argument to the JOIN command reply, mainly
1337 for the server to identify for which client the command was
1338 originally sent. Updated protocol specs accordingly.
1340 * Added SilcDlist private_key pointer to the SilcChannelEntry
1341 in the client to support the channel private keys. Affected
1342 file is lib/silcclient/idlist.h.
1344 * Added SilcChannelPrivateKey argument to the function
1345 silc_client_send_channel_message so that application can choose
1346 to use specific private ke if it wants to. If it is not provided,
1347 the normal channel key is used, unless private keys are set.
1348 In this case the first (key that was added first) is used
1349 as the encryption key.
1351 * Implemented the support for channel private key handling.
1352 Implemented the following functions:
1354 silc_client_add_channel_private_key,
1355 silc_client_del_channel_private_keys,
1356 silc_client_del_channel_private_key,
1357 silc_client_list_channel_private_keys and
1358 silc_client_free_channel_private_keys
1360 Affected file lib/silcclient/client_channel.c.
1362 * Added the support for the private keys in the channel message
1363 sending and encryption and in the message reception and
1364 decryption. Affected funtions are
1365 silc_client_send_channel_message and silc_client_channel_message.
1367 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1369 * Added SKE's key verify callback to the client library's
1370 KE protocol context. Affected files lib/silcclient/protocol.[ch].
1372 * Removed the statement that server (or router) must send USERS
1373 command reply when joining to the channel so that the client
1374 knows who are on the channel. Instead, the client list and
1375 client's mode list is now sent in the JOIN command reply to the
1376 client who joined channel. This is better solution.
1378 * Added function silc_server_get_users_on_channel and function
1379 silc_server_save_users_on_channel to the silcd/server.[ch].
1381 * Removed function silc_server_command_send_users from the
1384 * Do not show topic on the client library anymore. The topic is
1385 sent in the command reply notify to the application and the
1386 application must show the topic now.
1388 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * Added client searching by nickname hash into the IDENTIFY and
1391 WHOIS commands in the server as they were clearly missing from
1392 them. Affected file is silcd/command.c.
1394 * Fixed a bug in private message receiving in the client library.
1395 The remote ID was freed and it wasn't supposed, now it is
1398 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1400 * Minor fix to the channel payload; allocate the data area, as it
1401 needs to be of specific length.
1403 * If the key agreement port is zero then the operating
1404 system will define the bound port. Affected files are
1405 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
1407 * Added new function silc_channel_payload_decrypt into the file
1408 lib/silccore/silcchannel.[ch].
1410 * Moved the channel message etc, check from silc_packet_decrypt
1411 to applications. The library calls now a generic
1412 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
1413 when the packet is either normal or special. This was done to
1414 allow more wide range of checking that was not allowed when
1415 the code was in library. Now applications can do virtually any
1416 checks to the packet and return to the library the decision how
1417 the packet should be processed. Affected files are
1418 lib/silccore/silcpacket.[ch].
1420 Added silc_server_packet_decrypt_check to the server and
1421 silc_client_packet_decrypt_check to the client library.
1423 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
1424 to send with specified source and destination information.
1426 * Channel message delivery between routers was broken after the
1427 channel key distribution was fixed earlier. The channel key
1428 was used be to distributed to other routers as well which is not
1429 allowed by the protocol. Now this is fixed and channel keys
1430 really are cell specific and the channel message delivery between
1431 routers comply with the protocol specification.
1433 * Fixed various commands in server to check also the global list
1434 for the channel entry and not just the local list. The affected
1435 file silcd/command.c.
1437 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1439 * Added assert()s to buffer formatting and unformatting routines
1440 to assert (if --enable-debug) when error occurs. Affected
1441 file: lib/silcutil/silcbuffmt.c.
1443 * Changed to auto-reconnect to check whether the remote host is
1444 router and register the re-connect timeout if it is. It used
1445 to check that whether we are normal server, but router must do
1446 auto-reconnect with another router as well. Affected file
1449 * Removed the [<key len>] option from CMODE command as the cipher
1450 name decides the key length, nowadays. See the defined ciphers
1451 from the protocol specification.
1453 * Added [<hmac>] option to the CMODE command to define the HMAC
1454 for the channel. Added SILC_CMODE_HMAC channel mode.
1456 * Added [<hmac>] option for the JOIN command so that user can
1457 select which HMAC is used to compute the MACs of the channel
1460 * Added Hmac field to the Channel Message Payload. The integrity
1461 of plaintext channel messages are now protected by computing
1462 MAC of the message and attaching the MAC to the payload. The
1463 MAC is encrypted. Now, it is clear that this causes some
1464 overhead to the size of the packet but rationale for this is that
1465 now the receiver can verify whether the channel message decrypted
1466 correctly and also when private keys are set for the channel the
1467 receiver can decrypt the packet with several keys and check from
1468 the MAC which key decrypted the message correctly.
1470 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
1471 lib/silccrypt/silccipher.[ch].
1473 * Added silc_hash_len to return the digest length into the
1474 lib/silcrypt/silchash.[ch].
1476 * Rewrote parts of Silc Channel Payload interface in the
1477 lib/silccore/silcchannel.[ch]. The encode function now also
1478 encrypts the packet and parse function decrypts it.
1480 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1482 * Fixed a minor formatting bug in the SKE's key material processing.
1483 It actually might have processed the keys wrong way resulting
1486 * Redefined the mandatory HMAC algorithms and added new algorithms.
1487 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
1488 and hmac-md5 truncated to 96 bits. The mandatory is now
1489 hmac-sha1-96. Rest are optional (including the one that used
1490 to be mandatory). Rationale for this is that the truncated HMAC
1491 length is sufficient from security point of view and can actually
1492 make the attack against the HMAC harder. Also, the truncated
1493 HMAC causes less overhead to the packets. See the RFC2104 for
1496 * Added new [hmac] configuration section. The SKE used to use
1497 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
1498 is of course wrong. The official names that must be proposed in
1499 the SKE are the ones defined in the protocol specification
1500 (hmac-sha1-96 for example). The user can configure any hmac
1501 using any hash function configured in the [hash] section. At
1502 least, the mandatory must be configured.
1504 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
1506 * Added HMAC list to the SKE proposal list. It has now both
1507 hash algorithm list and HMAC list. This makes the protocol
1508 incompatible with previous versions. The SKE now seems to work
1509 the way it is supposed to work, for the first time actually.
1511 * Defined plain Hash algorithms to the protocol specification.
1514 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1516 * Implemented support for key agreement packets into the server.
1517 Added functions silc_server_key_agreement and
1518 silc_server_send_key_agreement. Other than these functions,
1519 server has nothing to do with this packet.
1521 * Added support for private message key packets into the server.
1522 Added functions silc_server_private_message_key and
1523 silc_server_send_private_message_key.
1527 * Changed the silc_[client|server]_protocol_ke_set_keys to be
1528 called in the protocol's final callback instead in the END
1529 protocol state. This makes a little more sense and in the same
1530 time in client we can use the same protocol routines for normal
1531 key exchange and to key agreement packet handling as well.
1533 * Added to both client's and server's KE protocol context the
1534 SilcSKEKeyMaterial pointer to save the key material. We will
1535 bring the key material to the protocol's final callback by doing
1536 this. The final callback must free the key material.
1538 * Added SKE's packet_send callback into client's KE protocol
1539 context so that the caller can choose what packet sending function
1540 is used. This way we can use different packet sending when
1541 doing normal SKE when doing key agreement packet handling (in
1542 the key agreement packet handling we do not want to encrypt
1545 * Implemented the responder side of the key agreement routines
1546 in the client. The client can now bind to specified port and
1547 accept incoming key negotiation. The key material is passed
1548 to the application after the protocol is over.
1550 * Implemented the processing of incoming Key Agreement packet
1551 in the client. Added function silc_client_key_agreement to
1554 * Implemented the intiator side of the key agreement routines
1555 in the client. The client can now initiate key agreement with
1556 another remote client. The key material is passed to the
1557 application after the protocol is over.
1559 * Created client_keyagr.c to include all the key agreement
1562 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
1563 SILC_TASK_CALLBACK except that it is not static.
1565 * Created client_notify.c and moved the Notify packet handling
1566 from the client.[ch] into that file.
1568 * Created client_prvmsg.c and moved all private message and
1569 private message key routines from the client.[ch] into that file.
1571 * Create client_channel.c and moved all channel message and
1572 channel private key routines from the client.[ch] into that file.
1574 * Changed silc_client_get_client_by_id_resolve to resolve with
1575 WHOIS command instead of IDENTIFY command, in the file
1576 lib/silclient/idlist.c.
1578 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1580 * Implemented the SKE's responder side to the Client library.
1582 * When FAILURE is received to the protocol do not trust it
1583 blindly. Register a timeout to wait whether the remote closes
1584 the connection as it should do it, only after that process the
1585 actual failure. This was changed to both client and server.
1587 * Added client_internal.h to include some of the structures
1588 there instead of client.h in lib/silcclient/.
1590 * Added function silc_task_unregister_by_callback to unregister
1591 timeouts by the callback function.
1593 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Some "Incomplete WHOIS info" errors has been appearing on the
1596 log files. Took away the entry->userinfo check from WHOIS
1597 reply sending. The entry->userinfo is now " " if client did not
1598 provide one. I thought this was fixed earlier but something
1599 is wrong still. Let's see if the error still appears.
1601 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1603 * Fixed a minor bug in the login when the channel key is
1604 re-generated in the server. It used to generate the key in
1605 wrong order and thus caused problems in the channel traffic.
1607 * Fixed a minor bug in channel key distsribution after
1608 KICK command. The key was not sent to the router even though
1611 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1613 * Added silc_ske_process_key_material_data as generic routine
1614 to process any key material as the SILC protocol dictates. The
1615 function is used by the actual SKE library but can be used by
1616 applications as well. This relates to the private message keys
1617 and the channel private keys since they must be processed the
1618 same way the normal SILC session keys. The protocol dictates
1619 this. Affected files: lib/silcske/silcske.[ch].
1621 Added also silc_ske_free_key_material to free the
1622 SilcSKEKeyMaterial structure.
1624 * Defined silc_cipher_set_key function to set the key for
1625 cipher without using the object's method function. The affected
1626 files: lib/silccrypt/silccipher.[ch].
1628 * Implemented silc silc_client_add_private_message_key,
1629 silc_client_add_private_message_key_ske,
1630 silc_client_del_private_message_key,
1631 silc_client_list_private_message_keys and
1632 silc_client_free_private_message_keys functions in the
1635 Added functions silc_client_send_private_message_key to send
1636 the Private Message Key payload and silc_client_private_message_key
1637 to handle incoming Private Message Key payload.
1639 * Added Cipher field to the Private Message Key payload to set
1640 the cipher to be used. If ignored, the default cipher defined
1641 in the SILC protocol (aes-256-cbc) is used.
1643 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1645 * Removed lib/silcclient/ops.h file.
1647 Redefined parts of the SILC Client Library API. Created new
1648 file silcapi.h that deprecates the ops.h file and defines the
1649 published Client Library API. Defined also private message key
1650 API and channel private key API into the file.
1652 This is the file that the application must include from the
1653 SILC Client Library. Other files need not be included by
1654 the application anymore.
1656 * Added new key_agreement client operation callback and also
1657 defined the Key Agreement library API for the application.
1659 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1661 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
1662 is used by clients to request key negotiation between another
1663 client in the SILC network. If the negotiation is started it
1664 is performed using the SKE protocol. The result of the
1665 negotiation, the secret key material, can be used for example
1666 as private message key.
1668 Implemented the Key Agreement payload into the files
1669 lib/silccore/silauth.[ch].
1671 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1673 * Redefined ciphers for the SILC protocol. Added some new ciphers
1674 and defined the key lengths for the algorithms. Changed the
1675 code accordingly. The default key length is now 256 bits.
1677 * Fixed SKE key distribution function silc_ske_process_key_material
1678 when the key length is more than 128 bits. The default key
1679 length in SILC is now 256 bits.
1681 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
1682 to indicate unsupported algorithm.
1684 * Renamed rijndael.c to aes.c and all functions as well.
1686 * Fixed a long standing channel key setting bug in client library.
1687 Weird that it has never surfaced before.
1689 * Fixed bug in channel deletion. If the entire channel is removed
1690 then it must also delete the references of the channel entry
1691 from the client's channel list as the client's channel entry and
1692 the channel's client entry share same memory.
1694 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1696 * Implemented CONNECT and SHUTDOWN commands in the client.
1698 * Implemented CLOSE command to the client.
1700 * Added the function silc_idlist_find_server_by_name into the
1701 files silcd/idlist.[ch].
1703 Added the function silc_idlist_find_server_by_conn into the
1704 files silcd/idlist.[ch].
1706 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1708 * DIE command was renamed to SHUTDOWN. Updated the both code
1711 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
1712 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
1714 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
1717 * Added function silc_server_create_connection function to create
1718 connection to remote router. My server implementation actually
1719 does not allow router to connect to normal server (it expects
1720 that normal server always initiates the connection to the router)
1721 so the CONNECT command is only good for connecting to another
1724 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
1727 or some other client was kicked from the channel.
1729 Implemented the handling of the notify type to both client
1732 Implemented silc_server_send_notify_kicked to send the KICKED
1733 notify. It is used to send it to the server's primary router.
1735 * Implemented the KICK command into server and client.
1737 * Added `query' argument to the silc_idlist_get_client function
1738 to indicate whether to query the client from server or not if
1741 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
1742 to indicate that the client is not channel founder.
1746 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1748 * Removed the rng context from SilcPacketContext structure and
1749 changed that the packet routine uses the Global RNG API.
1751 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1753 * Added support for quit message that client can "leave" on the
1754 channel when it quits the SILC. It is ditributed inside the
1755 SILC_NOTIFY_TYPE_SIGNOFF notify type.
1757 Added silc_server_free_client_data that will take the
1758 signoff message as argument.
1760 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
1762 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1764 * Updated parts of the protocol specification to keep it up
1767 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1769 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
1770 payloads in one packet.
1772 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
1773 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
1774 use now the new List flag.
1776 * Also deprecated the following packet types: REPLACE_ID,
1777 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
1779 * Added list support for Notify packet in server.
1781 * Added silc_server_send_notify_channel_change to send the
1782 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
1783 the silc_server_send_replace_id.
1785 * Added silc_server_send_notify_nick_change to send the
1786 NICK_CHANGE notify type. Deprecates the function
1787 silc_server_send_replace_id.
1789 * Added silc_server_send_notify_join to send the JOIN notify type.
1790 Deprecates the function silc_server_send_new_channel_user.
1792 * Added silc_server_send_notify_leave to send LEAVE notify type.
1793 Deprecates the function silc_server_send_remove_channel_user.
1795 * Added silc_server_send_notify_cmode and
1796 silc_server_send_notify_cumode to send CMODE and CUMODE notify
1797 types. Deprecates the silc_server_send_set_mode function.
1799 * Added SERVER_SIGNOFF notify type to indicate that server has
1800 quit. This means that all clients on the channel from that
1801 server will drop. This can be also used when netsplit happens.
1803 Deprecated REMOVE_ID packet type since it is not needed anymore
1806 Added silc_server_send_notify_server_signoff to send the
1807 SERVER_SIGNOFF notify type. Deprecates the function
1808 silc_server_send_remove_id.
1810 Added also silc_server_send_notify_signoff to send the
1811 SIGNOFF notify type.
1813 * Employed the PKCS #1. It is the mandatory way to do RSA in the
1814 SILC protocol from this day on. Changed the protocol
1815 specification as well.
1817 * Added silc_server_send_notify_topic_set to send TOPIC_SET
1818 notify type. It is used between routers to notify about
1819 topic changes on a channel.
1821 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
1824 * Partly updated the protocol specification to comply with the
1825 changes now made. It is still though a bit outdated.
1827 * The JOIN notify type now takes one extra argument <Channel ID>.
1828 The packet used to be destined to the channel but now the
1829 JOIN type may be sent as list thus it is impossible to
1830 destine it to any specific channel. By adding this argument
1831 it is again possible.
1833 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1835 * Added CREDITS file. The CHANGES and CREDITS file will appear
1836 in the distribution as well.
1838 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1840 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
1841 types in the server's silcd/packet_receive.c.
1843 * Implemented CMODE and CUMODE to work in router environment.
1845 * Fixed minor encoding and decoding buglet from the
1846 lib/silccore/silcmode.c.
1848 * Fixed buffer overflow from lib/silcclient/command.c in USERS
1851 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
1853 * Changed all SilcConfigServer* and silc_config_server* to
1854 SilcServerConfig* and silc_server_config*, respectively.
1857 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1859 * Associated the ID (client or server ID) to the Authentication
1860 Payload to avoid any possibility of forging. Updated the
1861 protocol specification and the code accordingly.
1863 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1865 * The RSA key length is now save to the RsaKey context in the
1866 key generation process in lib/silccrypt/rsa.c. The key length
1867 is now used to figure out the maximum size of the block allowed
1868 to be encrypted/signed.
1870 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
1871 is equivalent to the silc_mp_mp2bin but does not allocate any
1874 * Changed silc_mp_mp2bin API to take length argument. If it is
1875 non-zero then the buffer is allocated that large. If zero, then
1876 the size is approximated using silc_mp_sizeinbase, which however
1879 * Created Global RNG API which is global RNG that application can
1880 initialize. After initializing, any routine anywhere in the
1881 code (including library) can use RNG without allocating a new
1882 RNG object. This was done to allow this sort of use of the
1883 RNG in code that has no chance to allocate RNG object. All
1884 applications currently allocate this and many routines in the
1885 library use this. Affected file lib/silccrypt/silcrng.[ch].
1887 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
1888 it to use the Global RNG API.
1890 * Defined Authentication Payload into protocol specification that
1891 is used during SILC session to authenticate entities. It is
1892 used for example by client to authenticate itself to the server
1893 to obtain server operator privileges.
1895 Implemented this payload into the lib/silccore/silcauth.[ch].
1896 Implemented also routines for public key based authentication
1897 as the new protocol specification dictates.
1899 Moved definitions of different authentication methods from
1900 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
1902 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
1903 silc_pkcs_verify and silc_pkcs_sign_with_hash and
1904 silc_pkcs_verify_with_hash functions into the file
1905 lib/silccrypt/silcpkcs.[ch].
1907 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1909 * The client entry's userinfo pointer must be always valid.
1910 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
1911 will fail since it requires the userinfo. Now, the userinfo
1912 is allocated as "" if actual userinfo does not exist. Actually,
1913 it must exist and it is totally Ok to drop client connections
1914 that does not announce the userinfo. However, we will make
1915 this workaround for now.
1917 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
1918 to return the remote port by socket.
1920 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1922 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
1923 SILC_SERVER_PENDING_EXEC and added an new macro
1924 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
1925 data or when error occurs while processing the pending command.
1927 Added new argument `destructor' into silc_server_command_pending
1928 and to the SilcServerCommandPending object. This destructor is
1929 now called after calling the pending callback or if error occurs
1930 immediately. If error occurs the actual pending callback won't
1931 be called at all - only the destructor. The destructor may be
1932 NULL if destructor is not needed.
1934 All this applies for client library code as well. Similar
1935 changes were made there as well for the pending commands.
1937 In the client, the application must now allocate the
1938 SilcClientCommandContext with the silc_client_command_alloc
1941 * Added reference counter to the SilcServerCommandContext. Added
1942 function silc_server_command_alloc and silc_server_command_dup
1945 Same type of functions added to the client library for the same
1948 * Removed the cmd_ident from IDListData away since it is now
1949 global for all connections. It is the command identifier used
1950 in command sending and with pending commands. The affected file
1953 * Added reference counter to the SilcSocketConnection objecet to
1954 indicate the usage count of the object. The object won't be
1955 freed untill the reference counter hits zero. Currently only
1956 server uses this, and client ignores it. The client must be
1957 set to use this too later. The affected files are
1958 lib/silccore/silcsockconn.[ch]. Added also the function
1959 silc_socket_dup to increase the reference counter.
1961 This was mainly added because it is possible that the socket
1962 is removed underneath of pending command or other async
1963 operation. Now it won't be free'd and proper DISCONNECTING
1964 flags, etc. can be set to avoid sending data to connection that
1965 is not valid anymore.
1967 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
1968 the connection. After that it sets SILC_SET_DISCONNECTED.
1969 It is, however, possible that the socket data is not still freed.
1970 The silc_server_packet_process now checks that data is not
1971 read or written to connection that is DISCONNECTED. The socket
1972 get's freed when the reference counter hits zero.
1974 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1976 * Changed the client operation API: channel_message operation's
1977 `sender' is now the client entry of the sender, not the nickname
1978 and the `channel' is the channel entry, not the channel name.
1980 In the private_message operation the `sender' is now also the
1981 client entry of the sender not the nickname.
1983 Affected file is lib/silcclient/ops.h and all applications
1984 using the client operations.
1986 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1988 * Moved the calling of ops->connect() from connect_to_server_final
1989 into receive_new_id functin since that is the point when the
1990 client is actually allowed to send traffic to network. The
1991 affected file is lib/silcclient/client.c.
1993 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1995 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
1996 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
1997 (if needs broadcasting) instead of broadcasting the packets one
1998 by one which would make a burst in the network traffic.
2000 * Added `broadcast' argument to the functions in silcd/server.[ch]
2001 silc_server_create_new_channel[_with_id] to indicate whether
2002 to send New Channel packet to primary router.
2004 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2006 * Added new function into the silcd/server.[ch] files:
2007 silc_server_create_new_channel_with_id to create new channel with
2008 already existing Channel ID.
2010 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
2011 lib/silccore/silcpacket.h. This packet is used t send list of
2012 Set Mode payloads inside one packet. Server uses this to set
2013 the modes for the channels and clients on those channels, that it
2014 announced to the router when it connected to it. The protocol
2015 specification has been updated accordingly.
2017 * The silc_server_new_channel did not handle the packet coming
2018 from normal server as it normally does not send that. However,
2019 when it announces its channels it does send it. Implemented
2020 the support for that.
2022 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
2023 into the file lib/silccore/id.h.
2025 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2027 * Fixed memory leaks in the functions silc_idlist_del_client,
2028 silc_idlist_del_channel and silc_idlist_del_server in the file
2029 silcd/idlist.c. All of those leaked like a sieve.
2031 * Fixed some small memory leaks in the client's function
2032 silc_client_notify_by_server.
2034 * Added functions into silcd/server.c: silc_server_announce_clients,
2035 silc_server_announce_channels and silc_server_announce_server.
2036 These functions are used by normal and router server to announce
2037 to its primary router about clients, channels and servers (when
2038 router) that we own. This is done after we've connected to the
2041 These functions effectively implements the following packet types:
2042 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
2043 and SILC_PACKET_NEW_ID_LIST.
2045 * Added new functions into the silcd/packet_receive.[ch]:
2046 silc_server_new_id_list, silc_server_new_channel_list and
2047 silc_server_new_channel_user_list to handle the incoming
2048 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
2050 * Added support of changing Channel ID in the function
2051 silc_server_replace_id. If the server that announces a channel
2052 to the router already exists in the router (with same name but
2053 with different Channel ID), router is responsible to send
2054 Replace ID packet to the server and force the server to change
2055 the Channel ID to the one router has.
2057 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
2058 client that the Channel ID has been changed by the router. The
2059 normal server sends this to the client. Client must start using
2060 the new Channel ID as the channel's ID.
2062 Implemented handling of this new type into lib/silcclient/client.c
2063 into the function silc_client_notify_by_server.
2065 * Added new function silc_idlist_replace_channel_id into the files
2066 silcd/idlist.[ch] to replace the Channel ID.
2068 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2070 * Call silc_server_command_identify_check always when processing
2071 the IDENTIFY command in silcd/command.c
2073 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2075 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
2076 send keepalive packets. The packet can be sent by clients,
2077 servers and routers.
2079 Added function silc_socket_set_heartbeat into the file
2080 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
2081 If not set, the heartbeat is not performed. The actual
2082 heartbeat is implemented in the low level socket connection
2083 library. However, application is responsible of actually
2086 Added silc_server_send_heartbeat to send the actual heartbeat
2087 packet into silcd/packet_send.[ch]. Server now performs
2088 keepalive with all connections.
2090 * Added silc_task_get_first function into lib/silcutil/silctask.c
2091 to return the timeout task with shortest timeout. There was a bug
2092 in task unregistration that caused problems. TODO has been
2093 updated to include that task system must be rewritten.
2095 * The client library will now resolve the client information when
2096 receiving JOIN notify from server for client that we know but
2097 have incomplete information.
2099 * Rewrote parts of silc_server_remove_from_channels and
2100 silc_server_remove_from_one_channel as they did not remove the
2101 channel in some circumstances even though they should've.
2103 * Encryption problem encountered in server:
2105 The LEAVE command used to send the Channel Key packet to the
2106 router immediately after generating it. However, the code
2107 had earlier sent Remove Channel user packet but not immediately,
2108 ie. it was put to queue. The order of packets in the router
2109 was that Channel Key packet was first and Remove Channel User
2110 packet was second, even though they were encrypted in the
2111 reverse order. For this reason, MAC check failed. Now, this
2112 is fixed by not sending the Channel Key packet immediately but
2113 putting it to queue. However, this is more fundamental problem:
2114 packets that are in queue should actually not be encrypted
2115 because packets that are sent immediately gets encrypted
2116 actually with wrong IV (and thus MAC check fails). So, packets
2117 that are in queue should be encrypted when they are sent to
2118 the wire and not when they put to the queue.
2120 However, the problem is that the current system has not been
2121 designed to work that way. Instead, the packet is encrypted
2122 as soon as possible and left to the queue. The queue is then
2123 just purged into wire. There won't be any fixes for this
2124 any time soon. So, the current semantic for packet sending
2127 o If you send packet to remote host and do not force the send
2128 (the packet will be in queue) then all subsequent packets to the
2129 same remote host must also be put to the queue. Only after the
2130 queue has been purged is it safe again to force the packet
2133 o If you send all packets immediately then it safe to send
2134 any of subsequent packets through the queue, however, after
2135 the first packet is put to queue then any subsequent packets
2136 must also be put to the queue.
2138 Follow these rules and everything works fine.
2140 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2142 * Added new function silc_server_remove_clients_by_server to
2143 remove all client entries from ID list when the server connection
2144 is lost. In this case it is also important to invalidate all
2145 client entires as they hold the invalid server entry. This
2146 fixes fatal bug when server has lost connection and will reconnect
2149 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2151 * Made some sanity checks to silc_server_daemonise like to check
2152 whether the requested user and group actually exists.
2154 * Added sanity check to SKE's silc_ske_responder_finish to check
2155 that the public and private key actually is valid.
2157 * Invalidate the client's nickname when receiving Replace ID
2158 packet and the Client ID is being replaced. This means that the
2159 server will query the nickname if someone needs it (client)
2162 * Sort the ID Cache in client library when the ID Cache data
2163 has changed (needs sorting).
2165 * Do not allow for SILC client to create several connections to
2166 several servers. The client does not support windows right now
2167 and generating multiple connections causes weird behaviour.
2169 Irssi-silc client does support windows and can handle several
2170 connections without problems, see: www.irssi.org and SILC plugin.
2172 * Fixed some places where client was added to the IDList. The
2173 rule of thumb is following (in order to get everything right):
2174 If the client is directly connected local client then the
2175 `connection' argument must be set and `router' argument must be
2176 NULL to silc_idlist_add_client function. If the client is not
2177 directly connected client then the `router' argument must
2178 bet set and the `connection' argument must be NULL to the
2179 silc_idlist_add_client function.
2181 * The funtion silc_server_packet_send_local_channel actually did
2182 not check whether the client was locally connected or not. It
2183 does that now. Fixed a bug related to LEAVE command.
2185 * Fixed Remove Channel User payload parsing bug in server's
2186 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
2188 * The server's silc_server_save_channel_key now checks also the
2189 global ID list for the channel as it might not be in the local
2190 list. Fixed a bug related to LEAVE command.
2192 * Is this the end of the [<unknown>] buglet that has been lurking
2193 around for a long time? A little for loop fix in server's
2194 silc_server_command_whois_parse that is used by both IDENTIFY
2195 and WHOIS command. At least, this was a clear bug and a cause
2196 of one type of [<unknown>] buglet.
2198 * WHOIS and IDENTIFY commands call the function
2199 silc_server_command_[whois/identify]_check function even if
2200 we are not router server.
2202 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2204 * Added --with-gmp configuration option. If set the GMP
2205 is always compiled in the SILC source tree. If not set then
2206 it is checked whether the system has the GMP3 installed. If
2207 it has then the GMP won't be compiled (the system's headers
2208 and library is used), if it doesn't have it then the GMP is
2209 compiled in the SILC source tree.
2211 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2213 * Changed RSA private exponent generation to what PKCS #1
2214 suggests. We try to find the smallest possible d by doing
2215 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
2216 not security fix but optimization.
2218 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2220 * Added new config entry [Identity] to fork the server and run
2221 it as specific user and group. A patch from Bostik.
2223 * Imported Dotconf configuration library into lib/dotconf.
2224 This will be used to create the SILC configuration files later.
2225 It will appear in the distsribution after this commit.
2227 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2229 * A big code auditing weekend happening. Auditing code for
2230 obvious mistakes, bugs and errors. Also, removing any code
2233 Removed files for being obsolete:
2235 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
2236 inline in the file lib/silcutil/silcbuffer.h)
2238 o lib/silcutil/silcbufutil.c (the header has inline versions)
2240 Changed code to fix possible error conditions:
2242 o The buffer formatting routines now check that the destination
2243 buffer really has enough space to add the data. This applies for
2244 both buffer formatting and unformatting
2245 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
2246 unformatting was changed to accomodate following rules:
2247 XXX_*STRING_ALLOC will allocate space for the data into the pointer
2248 sent to the function while XXX_*STRING will not allocate or copy
2249 the data into the buffer. Instead it sets the pointer from the
2250 buffer into the pointer sent as argument (XXX_*STRING used to
2251 require that the pointer must be allocated already). This change
2252 makes this whole thing a bit more consistent and more optimized
2253 (note that the data returned in the unformatting with XXX_*STRING
2254 must not be freed now). The routines return now -1 on error.
2256 o Tried to find all code that use buffer_format and buffer_unformat
2257 and added return value checking to prevent formatting and
2258 especially unformatting errors and possible subsequent fatal
2261 o Changed ske->x and ske->KEY to mallocated pointers in
2262 lib/silcske/silcske.h. Fixed possible data and memory leak.
2264 o Added return value checking to all *_parse* functions. Fixed
2265 many memory leaks as well.
2267 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
2268 so that buffer overflows would not happen. All code now also
2269 checks the return value as it can fail.
2271 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2273 * Added reconnection support to server if the normal server looses
2274 its connection to the router (for example if router is rebooted).
2275 The server performs normal reconnection strategy implemented
2276 to the server. Affected file silcd/server.c.
2278 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2280 * Added new packet type SILC_PACKET_SET_MODE that is used to
2281 distribute the information about changed modes (for clients,
2282 channels and clients channel modes) to all routers in the
2283 network. Updated the protocol specification accordingly.
2285 Added functions into silcd/packet_send.c and
2286 silcd/packet_receive.c: silc_server_send_set_mode,
2287 silc_server_set_mode.
2289 Added new files silcmode.[ch] into lib/silccore that implements
2290 the encoding and decoding of Set Mode Payload. Added new type
2291 SilcSetModePayload. Moved the definitions of different modes
2292 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
2294 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2296 * Oops, a little mistake in server's connection authentication
2297 protocol. The protocol is not ended with FAILURE but with
2298 SUCCESS if the authentication is Ok. :) Affected file is
2301 * Implemented NICK_CHANGE notify handling in server in the file
2302 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
2303 the local clients on the channel. After the changing nickname
2304 in router environment snhould work and the [<unknown>] nickname
2305 should appear no more.
2307 The silc_server_replace_id function that receives the Replace ID
2308 payload now sends the NICK_CHANGE notify type also in the file
2309 silcd/packet_receive.c
2311 * Changed WHOIS and IDENTIFY command to support the maximum amount
2312 of arguments defined in protocol specs (3328 arguments). This
2313 fixed a bug that caused problems when there were more than three
2316 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2318 * Added extra parameter, command identifier, to the
2319 silc_client_send_command so that explicit command identifier
2322 Changed that ID list routines uses specific command identifier
2323 when sending WHOIS/IDENTIFY requests to the server so that they
2324 can be identified when the reply comes back.
2326 Affected files lib/silcclient/command.[ch],
2327 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
2329 * Added `sender' argument to silc_server_packet_send_to_channel
2330 to indicaet the sender who originally sent the packet to us
2331 that we are now re-sending. Ignored if NULL. Affected file
2332 silcd/packet_send.[ch].
2334 * Added some server statistics support in silcd/server_internal.h
2335 SilcServerStatistics structure and around the server code. Also
2336 send some nice statistics information when client is connecting
2339 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2341 * Fixed channel ID decoding in server's JOIN command reply in
2342 silcd/command_reply.c
2344 * Fixed braodcasting of replace ID payload to not to send it if
2345 we are standalone server in silcd/packet_receive.c.
2347 * Fixed all channel message sending routines to not to send
2348 packets to clients that has router set, since they are routed
2349 separately in the same function earlier. Affects file
2350 silcd/packet_send.c and all channel packet sending functions.
2352 * In USERS reply, res_argv[i] are not allocated, the table
2353 is allocated. Thus changed that free the table, not its
2356 * In server's whois_check and identify_check if the client is
2357 locally connected do not send any WHOIS commands - they are not
2360 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2362 * Fixed some minor bugs in client when sending WHOIS command. The
2363 arguments was in wrong order.
2365 * Removed statis function add_to_channel from server in
2366 silcd/command.c that was previously used with the joining but
2369 * Tested USERS command in router environment successfully with two
2370 routers, two servers and two clients.
2372 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2374 * Reorganized the USERS command and command reply in client library
2375 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
2376 When the command is given by user we register a pending command
2377 callback that will reprocess the command after the reply has been
2378 received from the server. When reprocessing the packet we then
2379 display the information. Thus, the USERS information is displayed
2380 now in the command callback instead of in the command reply
2381 callback. The processing of the command is same as previously
2382 when server has sent the command reply in the JOINing process.
2384 * Added to USERS command in silcd/command_reply.c to join the client,
2385 we didn't use to know about, to the channel after we've created
2386 a client entry for it. Also, for clienet we did know already still
2387 check whether it is on the channel or not and add it if not.
2389 * Removed silc_server_command_join_notify as the function and its
2392 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2394 * Changed the client's pending command handling to the same as the
2395 server's pending command handling. It is also now possible to
2396 execute command reply functions from other command reply
2397 function as the function callbacks for commands and command
2398 replies are one and same. The pending commands are not static
2399 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
2400 in client connection context. Thus, pending commands are server
2401 connection specific as it is convenient.
2403 Changed the function silc_client_command_pending and
2404 silc_client_command_pending_del and added new function
2405 silc_client_command_pending_check. Removed the
2406 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
2409 * Added cmd_ident, current command identifier, to the client
2410 connection context in lib/silcclient/client.h to keep track on
2411 command identifiers used in command sending. Client's command reply
2412 function handling now supports the mandatory command identifiers.
2414 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
2415 funtions in client to fully support pending command callbacks.
2417 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
2418 as one of the arguments to the application in the command reply
2421 * NOTE: The FORWARDED flag is depracated. It used to be depracated
2422 before first releasing SILC but came back. Now it is removed again
2423 and should come back nomore. The FORWARDED flag was used only
2424 by the JOINing procedure by forwarding the command packet to router.
2425 Now, the JOINing procedure has been changed to more generic (due
2426 to various router environment issues) and FORWARDED is not needed
2427 anymore for anything. The protocol specification is yet to be
2430 Now, removed silc_server_packet_forward from server and the flag
2431 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
2433 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2435 * Renamed NAMES command to USERS command. The NAMES was named that
2436 due to historical reasons. Now it is renamed. Also, rewrote
2437 parts of the USERS command. The nickname list is not sent anymore
2438 by the server. Only Client ID and mode lists are sent in the USERS
2439 command. Changed this also to the protocol specification.
2441 The client now resolves the names and stuff after it receives
2442 the USERS list from the server when joining to the channel.
2444 * WHOIS and IDENTIFY commands has been changed to support multiple
2445 Client ID's per command. One can now search for multiple users
2446 in the network by sending only one WHOIS or IDENTIFY command.
2447 Changed the code and the protocol specifications.
2449 * Removed silc_server_command_identify_parse and changed that IDENTIFY
2450 uses silc_server_command_whois_parse to parse the request. */
2452 * If normal server, do not parse the WHOIS and IDENTIFY requests
2453 before sending it to the router. Saves some time.
2455 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2457 * Fixed JOIN command on client library. Wrong number of arguments
2458 used to crash the client.
2460 * Added silc_server_channel_has_global function to check whether
2461 channel has global users or not.
2463 * Added silc_server_channel_has_local function to check whether channel
2464 has locally connected clients on the channel.
2466 * The silc_server_remove_from_one_channel now checks whether the
2467 channel has global users or not after given client was removed from
2468 the channel. It also checks whether the channel has local clients
2469 on the channel anymore. If it does not have then the channel entry
2470 is removed as it is not needed anymore.
2472 * The silc_server_notify now checks on JOIN notify whether the joining
2473 client is one of locally connected or global. If it is global then
2474 the channel has now global users on the channel and that is marked
2475 to the channel entry. Also, it now saves the global client to
2476 global list who is joining and JOINs it to the channel. This is
2477 for normal server, that is.
2479 Changed silc_server_send_notify_on_channel,
2480 silc_server_packet_relay_to_channel and
2481 silc_server_packet_send_to_channel check if we are normal server
2482 and client has router set (ie. global client) do not send the
2483 message to that client, as it is already routed to our router.
2485 * Implemented LEAVE notify type handling in silc_server_notify
2488 * Tested LEAVE command in router environment successfully. Tested
2489 with two routers, two servers and two clients.
2493 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
2495 * Implemented SIGNOFF notify type handling in silc_server_notify
2498 * silc_server_remove_id now removes the client entry from all channels
2499 it has joined and thusly sends SIGNOFF notify type.
2501 * Rewrote the NAMES list generation in server by removing two excess
2502 loops. The lists are created now inside one loop.
2504 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2506 * silc_server_remove_channel_user checks now also global list
2507 for channel and client.
2509 * silc_server_new_channel_user checks now both local and global
2510 list for channel and client. Fixed a bug in client id decoding.
2511 Used to decode wrong buffer.
2513 * silc_server_channel_message checks now both local and global
2514 list for channel entry.
2516 * Tested channel joining (hence JOIN) in router environment
2517 successfully. Tested with two routers, two servers and two
2520 * Tested channel message sending in router environment successfully.
2522 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
2524 * Added silc_server_save_channel_key into server.[ch] to save the
2525 received channel key in Channel Key payload processing. It is
2526 also used in JOIN command reply handling.
2528 Equivalent function silc_client_save_channel_key added into
2529 client.[ch] into client library.
2531 * Changed JOIN command reply to send information whether the channel
2532 was created or not (is existing already) and the channel key
2533 payload. Changed protocol specs accordingly.
2535 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
2536 the request was sent by ID and not by nickname. Crashed on
2539 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2541 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
2542 now correctly save the received data.
2544 * silc_server_free_sock_user_data now notifies routers in the
2545 network about entities leaving the network.
2547 At the same time implemented functions silc_server_remove_id
2548 and silc_server_send_remove_id to receive and send REMOVE_ID
2549 packets. The packet is used to notify routers in the network
2550 about leaving entities. The ID removed will become invalid in
2553 * Added function silc_idlist_del_server into server. Removes and
2554 free's server entry from ID list.
2556 * silc_server_private_message function now checks, if we are router,
2557 that the destination ID really is valid ID, naturally.
2559 * In router when NEW_ID packet is received (for new client) the
2560 hash of the Client ID is saved in the ID Cache but the
2561 client->nickname is set to NULL, instead of putting the hash
2564 IDENTIFY command now also checks that client->nickname must be
2565 valid. If it is not if will request the data from the server who
2566 owns the client. Added new function
2567 silc_server_command_identify_check.
2569 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
2570 to set the command to already allocated Command Payload.
2572 * Tested private message sending in router environment with two
2573 routers, two servers and two clients. Fixed minor bugs and now
2576 * Fixed segfault from client's NAMES command. Used to crash if
2579 * Forwarded packets must not be routed even if it is not destined
2580 to the receiver. Changed server code comply with this.
2582 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2584 * Added `require_reverse_mapping' boolean value to ServerParams
2585 structure. If TRUE (not default) the server will require that
2586 the connecting host has fully qualified domain name.
2588 If the reverse mapping is not required and hostname could not be
2589 found the IP address is used as hostname.
2591 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2593 * Implemented version string checking to both client and server.
2594 The check is incomplete currently due to the abnormal version
2595 strings used in development version of SILC.
2597 * Changed all command functions in server to use the new
2600 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2602 * Changed char *data to unsigned char *data in ID Cache system to
2603 support binary data as ID Cache data. Changed code to support
2604 binary data in lib/silccore/idcache.c.
2606 * Renamed silc_server_packet_relay_command_reply to
2607 silc_server_command_reply as it is normal packet receiving
2608 function. Rewrote the function to accept command replys for
2609 servers and not only for clients.
2611 * Mark remote router always as registered server if we are connecting
2612 to it. Otherwise, commands sent by the router to us are ignored.
2614 * All ID List find routines now returns the ID Cache Entry pointer
2615 as well if requested.
2617 * WHOIS command works now in router environment, tested with two
2618 routers, two servers and two clients.
2620 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
2621 in router environment (as it is almost equivalent to WHOIS) but
2622 hasn't been tested thoroughly. Added new functions:
2624 silc_server_command_identify_parse
2625 silc_server_command_identify_send_reply
2626 silc_server_command_identify_from_client
2627 silc_server_command_identify_from_server
2629 * Disabled route cache adding because adding two different ID's with
2630 same IP replaces the old cache entry thus giving wrong route.
2631 The entry->router->connection is always the fastest route anyway
2632 so route cache may not be needed. Of course, new routes maybe
2633 established after receiving the ID when the entry->router->connection
2634 might not be anymore the most optimal.
2636 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2638 * Add route cache for received ID for fast routing.
2640 * Added silc_server_packet_route to route received packet on router
2641 that is not destined to us.
2643 * Renamed silc_server_get_route to silc_server_route_get.
2645 * Added id_string and id_string_len fields into SilcServer to
2646 include encoded ServerID for fast comparing without excess
2647 encoding of the ID's.
2649 * Cleaned up WHOIS command on server side. Added following static
2652 silc_server_command_whois_parse
2653 silc_server_command_whois_check
2654 silc_server_command_whois_send_reply
2655 silc_server_command_whois_from_client
2656 silc_server_command_whois_from_server
2658 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
2659 arguments in command replies. All command functions should be
2660 updated to use this macro.
2662 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2664 * Minor typo fixes on command reply handling on server.
2666 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2668 * Added silc_server_command_add_to_channel internal routine to add
2669 the client to the channel after router has created the channel and
2670 sent command reply to the server.
2672 * Added generic silc_server_send_command to send any command from
2675 * Use static buffer with ID rendering instead of duplicating data.
2677 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2679 * Fixed a channel user mode bug when joining to a channel server gave
2680 everybody channel founder rights, oops.
2682 * We mark ourselves as the router of the incoming server connection
2683 if we are router ourselves. This way we can check in some packet
2684 sending functions whether it is locally connected server. For
2685 incoming router connections we put NULL.
2687 * For router sending packets locally means now always sending the
2688 packet cell wide; to local clients and local servers. For normal
2689 server sending packet locally means sending it to only local
2692 * Fixed the JOIN command to really work in router environment. If the
2693 channel is created it is always created by the router. Router is
2694 also responsible of making the initial joining to the channel,
2695 sending JOIN notify to the sending server and distributing
2696 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
2697 does not exist server doesn't do anything else but forward the
2698 command to the router which performs everything.
2700 * Added silc_server_send_channel_key function to send the Channel Key
2703 * Added silc_server_create_channel_key to create new channel key. The
2704 channel key is now re-generated everytime someone joins or leaves
2705 a channel, as protocol dictates. Note: channel->key_len is the
2708 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2710 * Splitted server.[ch] finally. Created now packet_send.[ch] and
2711 packet_receive.[ch] to separate packet sending and receiving
2712 routines. The server.[ch] now includes everything else including
2713 actual packet processing (writing and reading data) and other
2716 Renamed silc_server_private_message_send_internal to
2717 silc_server_send_private_message. The routine is still though
2718 used only to relay private messages as server does not send
2719 private messages itself.
2721 Renamed silc_server_new_channel to silc_server_create_new_channel
2722 and added new function sicl_server_new_channel that handles the
2723 incoming New Channel packet. Added also new sending function
2724 silc_server_send_new_channel to send New Channel Payload.
2726 * Added new function silc_server_notify to process incoming notify
2727 packet to the server/router. Server may then relay the notify
2728 to clients if needed.
2730 * Added new function silc_server_new_channel_user to process incoming
2731 New Channel User packet. Router will redistribute the packet and
2732 send JOIN notify to its local clients and locally connected servers
2733 if needed. Normal server will send JOIN notify to its local client
2734 on same channel when received this packet. Added also corresponding
2735 sending function silc_server_send_new_channel_user to sent the
2738 * Added boolean route argument to send_notif_to_channel and
2739 packet_send_to_channel functions to attempt to route the packet
2740 if it is TRUE and send only locally if it is FALSE.
2742 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2744 * silc_server_replace_id now broadcasts the received replace ID
2745 packet if it is not broadcast packet already. The router must
2746 broadcast to inform other routers about changed ID.
2748 * Added backpointer to server's router into SilcServer context in
2749 silcd/server_internal.h.
2751 * Fixed silc_server_packet_broadcast to send correct broadcast
2754 * The channel key is now distributed to the local client as soon
2755 as it is received from the router (in router environment) so that
2756 no other packet may be sent for the channel until client has
2759 * silc_server_remove_channel_user now broadcasts the received
2760 Remove Channel User packet if it is not broadcast packet already.
2761 The router must broadcast to inform other routers about removed
2764 * Added users field into SilcPacketContext that is a reference count
2765 of the context. One can increase the reference count by calling
2766 silc_packet_context_dup which is now changed to just increase the
2767 reference count instead of duplicating the data. The reference
2768 count is decresed by calling silc_packet_context_free that will
2769 free the data after the reference count hits zero.
2771 For now on the packet context and everything allocated into it
2772 (including the raw packet from network) must be freed by calling
2773 the new silc_packet_context_free function. Added also new function
2774 silc_packet_context_alloc that must be used now to allocate the
2775 context. This also means that if a routine is asynchronous from
2776 silc_[client/server]_packet_parse_type the packet context must
2777 be duplicated by calling silc_packet_context_dup. Otherwise it
2778 gets free'd after silc_[client/server]_packet_parse_type returns.
2779 Also, one must remember that if packet is duplicated then its
2780 reference count must be decresed by calling the free function as
2781 many times as it was duplicated.
2783 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
2784 from both client and server.
2786 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2788 * Made joining to a channel working in router environment.
2790 * Cleaned up JOIN command on server side and create function
2791 silc_server_command_join_channel internal routine to make the
2794 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2796 * Changed silc_command_pending list to SilcDList. Also, added
2797 `ident' field to SilcServerCommandPending structure to identify
2798 the reply and to call correct callback.
2800 Added silc_server_command_pending_check function to replace the
2801 corresnponding macro. The silc_command_pending list is not
2804 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
2805 to set identifier to previously allocated Command Payload. It
2806 is used to set identifier for command when resending Command
2809 * Added silc_command_payload_encode_payload to encode Command
2810 Payload buffer from SilcCommandPayload structure.
2812 * Added silc_argument_payload_encode_payload to encode Argument
2813 payload buffer from SilcArgumentPayload structure.
2815 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2817 * Changed WHOIS command to support router connection on server side.
2818 The whois request is always sent to router unless the server is
2819 standalone server. After server has received the reply from the
2820 router will it send the reply to the client.
2822 * Added silc_server_packet_broadcast into silcd/server.[ch] to
2823 broadcast received broadcast packet. The function is used only
2824 by router. The broadcast packet is always sent to the router's
2827 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
2828 render given ID to printable string, for log files for example.
2830 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2832 * Made basic router to router connections working. At least they
2833 can now connect to each other but nothing really works the way
2834 they are supposed - yet.
2836 * Added new initiator token to RouterConnection configuration
2837 file in silcd/serverconfig.[ch]. It is used to tell whether we
2838 are the initiator to the remote router or whether we'll expect
2839 the other end to connect.
2841 * Moved registering of listener task to silc_server_init, hence
2842 the server starts listenning as soon as it is run, even if it
2843 does not have connections to other routers. Let's see how well
2846 * Changed default connection retry timeouts for more suitable in
2849 * Removed cipher and such arguments from silc_idlist_add_client
2850 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
2851 Added new function silc_idlist_add_data to add the keys and stuff
2854 * Added SilcIDListData structure and added it to SilcClientEntry
2855 and SilcServerEntry as their first field in the structure. This
2856 way we can explicitly cast the ID entries to the SilcIDListData
2857 structure and get common data for the entries. In past, we had
2858 to first check what type of connection it is and then cast it to
2859 correct ID entry type. Now, we can directly cast the opaque
2860 pointer to the SilcIDListData (no matter what ID entry it actually
2861 is) and get the data needed.
2863 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2865 * Wow, found a bug in scheduler. The scheduler uninitialized itself
2866 in some circumstances even if threre were timeout tasks, though not
2867 IO tasks, but tasks anyway. Now fixed.
2869 * Defined SilcServerConnection structure to hold connection specific
2870 stuff about directly connected servers and routers. The definition
2871 is currently in silcd/server_internal.h. I thought about having
2872 a bit more important role fro this struct but for now it is used
2873 only when connecting to other server (or router actually).
2875 * Added connecting retry support in server when connecting to
2876 router(s). The retry feature implement exponential backoff
2877 algorithm. Also, added SilcServerParams structure to hold default
2878 parameters for server. For now, it include these retry settings
2879 and are hard coded. After server is moded to be as Silc Server
2880 Library this structure will be more important.
2882 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2884 * Changed client librarys channel->clients table to SilcList and
2885 changed code accordingly.
2887 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2889 * Changed client's channel table to SilcList and changed code
2890 accordingly. Also changed SilcChannelClientEntry to include back-
2891 pointer to the channel so that client entry can use that structure
2892 as list as well and we have fast cross-reference to the channel.
2893 This change dramatically decreased the complexity of channel
2894 handling with client entry and vice versa (removed one extra
2895 loop when searching for channel entry from many functions).
2897 * Changed server->sim from table to SilcDList and changed code
2900 * NAMES command can now be used from user interface. It will show
2901 the user list on the channel, neatly.
2903 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
2904 Code now saves realname of the user if it becomes available.
2906 * Renamed configure.in to configure.in.pre and made ./prepare
2907 script to automatically add correct version string to
2908 configure.in which it creates from configure.in.pre.
2910 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2912 * NAMES command reply now shows users mode with the nickname when
2915 * Moved silc_client_ch[u]mode[_char] functions from
2916 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
2917 place sucks, they are utility functions and should be in some
2920 * Fixed some unsigned int's to unsigned short's. Patch by cras.
2922 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
2925 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2929 * Added TRQ (efficient deque and list library) into lib/trq. This is
2930 a very good list library that is currently used in the SILC. Defined
2931 SilcList API over the library because I didn't like the API very
2932 much. See lib/trq/silclist.h for the API and examples of how to
2933 use the API. Fixed various places in the code to use the new
2934 SilcList API. The SilcList is meant for lists that has a structure
2935 already defined as a list. It is not suitable to add just some
2936 context to the list (in TRQ, the context is the list actually).
2938 So, I defined SilcDList that can be used for the purpose where
2939 predefined list structure does not exit. This can be used as
2940 such list. Now some context just can be added to the SilcDList.
2941 Currently this list is not used in the SILC just yet, though there
2942 are a lot places where this can replace dynamically allocated
2943 tables and I will fix these places, later, to use SilcDList.
2944 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
2945 and use TRQ internally).
2947 Also fixed some annoying warning messages that the original TRQ
2948 code generated. Also minor changes to TRQ's Makefile.in.
2950 * Added support for querying by Client ID to both WHOIS and
2951 IDENTIFY commands into server, as required by the protocol.
2953 * Removed method function pointers from SilcBuffer structure. They
2954 weren't used to anything and just increased the context size for
2955 no good reason. This change also made silc_buffer_alloc and
2956 silc_buffer_free functions inline functions.
2958 * Disabled command flooding detection support until it's fixed so
2959 that it accepts commands in but does not execute them more than once
2962 * Added silc_net_localhost(), to return local hostname, into
2963 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
2964 that must be initialized before calling silc_client_init.
2966 * Added new function: silc_server_send_notify_on_channels to send
2967 notify messages to all channels client has joined. It is assured
2968 that the message is sent only once per client.
2970 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
2971 lib/silcutil/silcutil.[ch] as silc_format function. The new
2972 function is generic and is used by server as well, not only by
2973 the logging routines.
2975 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
2976 the provided version string was not acceptable. Added new function:
2977 silc_ske_check_version into lib/silcske/silcske.h. The function
2978 must be implemented by the application (client or server) and it
2979 does not reside in the SKE library. The function checks the version
2980 string remote end sent.
2982 * Added back pointers (to opaque context and to SilcSocketConnection)
2983 into SilcPacketContext structure into lib/silccore/silcpacket.h.
2985 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
2986 duplicate packet context structure.
2988 * Changed `notify' client operation to send same arguments as client
2989 receives from server except for ID's. ID's are mapped to correct
2990 ID entry and that is returned. Also, if channel entry is not sent
2991 by server but the notify is for channel the channel entry is sent
2992 to application (otherwise application doesn't know that it is for
2993 channel (library gets it from packet's Destination ID)).
2995 * Added silc_client_remove_from_channels into client library to
2996 remove a client from all channels it has joined to. Used when
2997 received SIGNOFF notify from server. Added also new function
2998 silc_client_replace_from_channels to replace old ID entry with
2999 new ID entry on all channels. Used when received NICK_CHANGE
3002 * Fixed ID Cache list handling in silc_idlist_get_client in
3003 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
3004 to get (or query) client by ID.
3006 * Updated TODO list.
3008 * Added connection authentication status message defined by the
3009 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
3010 support for these into the code in client and server side.
3012 * Added generic function silc_client_send_command to send any command
3013 with variable argument list. Application should use this function
3014 to send commands if the command functions provided by the library
3015 does not suite for the application's user interface needs.
3017 * Added new `failure' client operation. Application is notified about
3018 received failure packet if client is executing a protocol. In this
3019 case the protocol's execution has failed.
3021 * Added SKE's end notify to send the SKE_SUCCESS notify message that
3022 is required by the protocol.
3024 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
3025 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
3028 * Added status flag to SilcSKE object to indicate realtime status
3029 of the SKE protocol.
3031 * Application receives now exactly same command reply arguments as
3032 the library receives from server. However, if ID is received the
3033 corresponding ID entry is returned to the application (eg. Client
3034 ID is mapped to correct SilcClientEntry entry and that is returned).
3035 Changed command_reply client operation due to this change.
3037 * Changed all ID's in commands and in command replys as ID Payloads.
3038 Change affected both client and server side codes.
3040 All ID's sent in SILC network (with execption of ID's in SILC
3041 Packet header) are sent in ID Payload to support variable length
3044 * Server now notifies nick changes and notifies all clients on
3045 the channels about the new nickname (about the new Client ID,
3048 * Implemented CMODE command to change channel modes. Supports all
3049 channel modes defined by the protocol specs except ban and invite
3050 lists. (Also, private channel key mode is supported but support for
3051 setting private channel key in client is missing, thus, this mode
3052 has no effect on client side (except that server requires that the
3053 client uses private channel key and normal channel traffic does not
3056 Also, invite mode works per se, but INVITE command does not work
3057 yet correctly, so you can set channel as invite only channel but
3058 inviting clients to the channel does not work (it is yet to be
3059 thought what's the best way to do it).
3061 * Added new command SILC_COMMAND_CUMODE to change user mode on the
3062 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
3063 Implemented CUMODE command to change user's mode on the channel.
3064 Supports all modes defined by the protocol specs.
3066 * Added NAMES command reply to return users modes on the channel.
3068 * Removed unnecessary and slow ciphers from lib/silccrypt.
3070 * Set SO_KEEPALIVE option to connection sockets by default.
3072 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
3074 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
3075 redefined the Notify Payload into protocol specs.
3077 * Added silc_id_payload_parse_id to get ID directly from raw
3080 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3082 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
3083 accept searching by Client ID as well.
3085 * Added support for LEAVE and SIGNOFF notify types in client library.
3087 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
3088 to parse ID Payload from raw data.
3090 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3092 * Added flags parameter into silc_ske_assemble_security_properties
3093 function in lib/silcske/silcske.[ch].
3095 * Changed notify client operation to fit better for notify messages
3096 sent by server. The notify payload received from server is now
3097 passed to the application (after parsing it to SilcNotifyPayload).
3098 It is application's responsibility to retrieve the arguments
3099 from the payload and show the message the way it wants. The message
3100 sent by server is implementation specific.
3102 * Changed public keys to comply with the protocol specification.
3103 Old public keys are not supported anymore and are not compatible.
3105 * Removed nickname from Channel Payload as the latest draft removed
3106 it. The client must resolve the nickname from the NAMES command
3107 reply received when it joined the channel.
3109 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
3111 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3113 * Fixed some errors in protocol specification drafts.
3115 * Created lib/silccore/silcnotify.c to implement Notify Payload
3116 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
3117 generic payloads described by protocol specifications. The file
3118 includes implementations for ID Payload and Argument Payload.
3120 * Changed Command Payload implementation to use the new Argument
3121 Payload. Changed command_xxxx_payload to command_payload_xxxx
3122 to comply with SILC coding conventions.
3124 * Added suppport for Argument Payload handling in Notify Payload
3125 implementation as protocol requires it. Added the new support
3126 into server and client lib as well.
3128 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3130 * Added support for multiple nicknames on same channel. [n] is
3131 added locally to the nickname if there are more than one same
3132 nicknames on the channel.
3134 * Server now sends all nicknames that matched WHOIS request.
3135 Client also shows the list received from server.
3137 * Added TOPIC command to client side. User can now set and show
3138 current topic on channel.
3140 * Added MOTD command to client and server. Also, server sends the
3141 motd when client connects to the server.
3143 * Changed version strings to comply ISO 8601.
3145 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3147 * Fixed protocol error handling in client library. It should now
3148 cope even if the SKE fails for some reason.
3150 * Made new protocol specification drafts for submitting to IETF.
3152 * Implemented TOPIC command to server in silcd/command.c.
3154 * Added two new notify types into lib/silccore/silcnotify.h:
3155 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
3156 notify nickname change and topic setting/change on a channel.
3158 * API change of command_reply operation in client library. The
3159 application gets now the status type received from server as well.
3161 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3163 * Removed the function just added to lib/silcutil/silcschedule.[ch].
3165 * Cras fixed and optimized the packet handling even further and
3166 it should work now. Minor change to the prototype of function
3167 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
3169 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3171 * Added new function into lib/silcutil/silcschedule.[ch]:
3172 silc_schedule_with_fd to select() a specified fd. The function
3173 returns after timeout expires or data arrives or goes. The
3174 function is used by packet routines to wait that all data is
3175 received from network.
3177 * Fixed data reading from network in lib/silccore/silcpacket.c.
3178 The code now assures that all data is read from the fd and then
3179 continues packet processing. This was a bug fix since the code
3180 used to drop some data in some circumstances.
3182 * Added new function into lib/silcclient/client.[ch]:
3183 silc_client_start_key_exchange to start key exchange after
3184 connection has been established to server. The code internally
3185 now uses this funtion but its main purpose was to provide it
3186 for applications that perform their own connecting. After
3187 application has created a connection it merely calls this
3188 function to start the key exchange between client and server.
3189 The library takes care of everything else after that.
3191 Updated also lib/silcclient/README to explain the usage of
3194 * Do not send to application information that connection has
3195 been established. Application gets notified it by connect
3198 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3200 * Applied cras's patch to add silc_schedule_one function. The
3201 function runs scheduler once and returns.
3203 * Fixed the scheduler after cras messed it up. The timeout
3204 handling works now as it's supposed to work.
3206 * Added into lib/silccore/ silcnotify.h to include notify
3207 message types support. Changed silc_server_send_notify*
3208 functions, in server.[ch], to support those new notify types.
3209 Added the support for the notify types into client library,
3210 as well. Added new notify client operation into ops.h in
3213 * Changed silc_server_packet_send_to_channel to send normal
3214 packets instead of just channel message packets. The function
3215 is now used to send the notify packets to channels. It is not
3216 used to send channel message packets anymore, as server never
3219 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
3220 va_arg()s as it seems to require it nowadays. I guess, if SILC
3221 is compiled with older va_arg() the new code should work anyway.
3223 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3225 * Splitted core library. Core library (lib/silccore) includes
3226 now only SILC protocol specific core (and common) components.
3227 Created new utility library (lib/silcutil) that includes more
3228 generic purpose stuff. The stuff for util library was taken
3229 from the old core library. This was minor and easy split.
3231 * Created SILC Client Library (lib/silcclient) that includes
3232 implementation of the SILC client without user interface. This
3233 was major move from silc/ directory. The code has been changed
3234 so that it is transparent towards the user interface. The
3235 silc/ directory includes now the same user interface as before
3236 and it uses the new client library. Read lib/silcclient/README.
3237 Basicly, the client library performs everything else related
3238 to SILC except user interface handling. Also, configuration
3239 files are considered to be part of user interface and library
3240 does not handle them.
3242 This change also changed a lot of structures, function naming etc.
3243 Most important change was that SilcClientWindow object was
3244 renamed to SilcClientConnection in the client library. Created
3245 also new file lib/silcclient/ops.h. Also added new files
3246 silc/local_command.[ch] and silc/client_ops.[ch].
3248 All these changes were made to make it easier for user interface
3249 designers to create what ever user interface for the SILC client
3252 It is also expected that the server will be moved to lib
3253 directory as well and SILC Server Library will be created;
3254 sometimes in the future.
3256 * Removed Local commands from lib/silccore/silccommand.h as
3257 they are application specific and new client library does not
3258 handle any of those anymore.
3260 * Several functions moved to lib/silcutil/silcutilc.[ch] from
3261 old client implementation in silc/.
3263 * Added support for callback functions in SILC_LOG_* macros.
3264 Application can now set its own callbacks that will be called
3265 instead of using the default functions that will always print
3266 the debug messages to stderr (or stdout). Also, debugging can
3267 now be disabled by setting silc_debug to FALSE and re-enabled by
3268 setting it to TRUE. Note, that logging will still work even
3269 if debugging is disabled.
3271 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
3272 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
3273 silc_log_reset_debug_callbacks.
3275 * To enable debugging in silc client one must give now -d
3276 option on command line.
3278 * Changed silc_schedule_init to automatically allocate task queues
3279 if they are not allocated before calling it.
3281 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3283 * Added GMP 3.1 into math library.
3285 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3287 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
3288 a channel in SILC network. The packet is used by servers and
3289 routers to notify other routers that user has left a channel.
3290 This little feature was missing until now. Added the feature
3291 to protocol specification as well.
3293 Added functions: silc_server_send_remove_channel_user and
3294 silc_server_remove_channel_user into server.[ch].
3296 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
3297 lib/silccore/silcpacket.h. However, they are not implemented
3300 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3302 * Fixed joining to a channel and sending channel messages
3303 between server and router. The channel message sending should
3304 now work inside a cell.
3306 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3308 * Fixed the private message sending between server and router.
3309 The private message sending should now work inside a cell.
3311 * Added silc_server_replace_id into server.[ch] to replace
3312 existing ID in the SILC network.
3314 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
3315 and silc_idlist_replace_server_id into idlist.[ch] in server.
3317 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3319 * Fixed the server to server connections. Server can again now
3320 connect to router. Router to router connections probably does
3323 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3325 * Added dynamic protocol registering support. Now protocols can
3326 registered and unregistered on the fly. Patch by cras.
3328 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3330 * Added lib/contrib directory to hold routines that some platforms
3331 don't have but are needed by SILC.
3333 * Added getopt.c, getopt1.c and getopt.h from GNU C library
3334 into lin/contrib to provide getopt() and getopt_long() for
3335 those who don't have it.
3337 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3339 * Added AWAY command to client. When away message is set and
3340 client receives a private message packet the client automatically
3341 replies to the sender with the away message.
3343 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
3344 bug seemed to be the cause of recent problems when compiling
3347 * Added version detection support to SKE protocol specification
3348 and added the new changes to the SKE implementation as well.
3349 There were other minor changes in the SKE protocol as well.
3351 Many changes in lib/silcske/silcske.[ch] and in
3352 lib/silcske/payload.[ch].
3354 * Added ^U functionality, clear input line. Patch from cras.
3356 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3358 * Mainly small bugfixes on core library. Fixed some debugging
3359 logging and buffer overflow in silclog.c.
3361 * Updated config.sub and config.guess on the distribution tree.
3363 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3365 * Added command lagging support in server. Client may execute
3366 commands now only once in two seconds.
3368 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3370 * Optimized packet reception. MAC computation and checking is now
3371 also more optimized. A lot previously duplicated code is now
3372 used as generic by both client and server.
3374 * Fixed key pair generation in clientutil.c
3376 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3378 * Added into lib/silccore/silcbufutil.[ch] new function;
3379 silc_buffer_realloc.
3381 * Moved generic packet sending/encryption functions to
3382 lib/silccore/silcpacket.[ch] from client and server. Some
3383 rewriting of the functions.
3385 * Moved all generic packet reception/decryption functions to
3386 lib/silccore/silcpacket.[ch] from client and server. The
3387 packet processing is now much cleaner in both client and server.
3388 These were major changes in both client and server.
3390 * Created many common functions in server to do packet sending.
3391 Previously code were duplicated a lot, this has been removed
3394 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3396 * Rewrote major parts of the ID cache system. Don't know
3397 whether it is better now or not but at least the API is more
3400 * Major rewrite on ID cache stuff on client because of the ID
3401 cache API changes. Added idlist.c to client.
3403 * Also major rewrite on ID cache stuff on server as well.
3404 Major rewrite of idlist.[ch]. SilcXXXList's are now named
3405 SilcXXXEntry's. We won't keep anymore idlist specific pointers
3406 in hand, instead they are all put into the ID cache system now.
3407 All server_idlist_* routines uses ID cache now instead of
3408 traversing its own lists (those lists does not exist anymore).
3409 SilcIDList though still exists. Also, SilcXXXEntry's are
3412 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3414 * Finally made the SKE implementation compliant to the protocol
3415 specification. All mp integers are now binary encoded as
3416 opposed being HEX encoded.
3418 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
3421 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
3422 functions: silc_[encode/decode]_pem. Also added function
3423 silc_encode_pem_file to PEM encode with newlines ('\n') for
3426 * SILC public keys are now encoded either PEM or binary. Same
3427 option is for private keys as well. By default private keys
3428 are binary encoded and public keys PEM encoded. Silly HEX
3429 encoding were removed.
3431 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
3432 function to create fingerprints.
3434 * Fixed a bug in SHA1; does not change the original data anymore.
3436 * Partly implemented INFO command on client and server side.
3437 Fixed CLEAR command. Changes to SERVER command; show current
3438 server(s) when giving command without arguments. Added
3439 VERSION command to client.
3441 * Added check to server that unregistered connections cannot
3442 execute commands (unless it is specificly allowed).
3444 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3446 * Fixed screen refresh.
3448 * Fixed channel joining bug from client. On some circumstances
3449 client tried to join to a channel it had already joined.
3451 * Added public key verification process into client's protocol.c.
3452 The client now verifies the public key from user and saves
3453 it into ~./silc/serverkeys/ directory.
3455 Added into: clientutil.[ch]: silc_client_verify_server_key.
3457 * Changed SKE protocol's silc_ske_initiator_finish function
3458 to accept callback function that verifies the received public
3459 key. Removed old silc_ske_verify_public_key function.
3461 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3463 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
3464 silc_pkcs_private_key[_data]_set.
3466 * Made the password and public authentication more cleaner in
3467 server's protocol.c.
3469 * Removed historic and obsolete protocol `channel_auth' from
3470 both client and server.
3472 * Removed wrong way of sending command status messages from
3473 server to client in server's command.c. The old way violated
3474 protocol specification.
3476 Changes to silccore/silccommand.[ch]: removed
3477 silc_command_encode_status_payload -> not needed anymore,
3478 changed silc_command_encode_payload_va to accept extra
3479 argument on variable argument list. The argument type must
3480 now be provided to the function. Also, added new function:
3481 silc_command_encode_reply_payload_va which is same as
3482 normal command_encode_payload_va except command status type
3483 is provided as extra argument.
3485 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3487 * Added ~./silc directory handling. The directory includes the
3488 public and private keys for the client.
3490 Added silc_client_check_silc_dir, silc_client_create_identifier
3491 and silc_client_load_keys.
3493 * Implemented SILC protocol compliant public key. Added public
3494 and private key saving to and loading from files.
3496 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
3497 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
3498 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
3499 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
3500 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
3502 Implemented: silc_pkcs_save_[public/private]_key[_data] and
3503 silc_pkcs_load_[public/private]_key.
3505 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3507 * Added silc_server_get_route (route.[ch]) to get connection
3508 data for the fastest route for given ID.
3510 * Implemented INVITE command on client and server. The command
3511 were re-defined in the SILC Protocol Specification and the
3512 implementation now complies with the specification.
3514 * Implemented PING command on client and server.
3516 * Implemented NAMES command on client and server. The server side
3517 supports currently only normal server not router server yet.
3518 Some changes to NAMES definition in SILC protocol specification.
3520 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3522 * Implemented LEAVE command on client and server.
3524 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
3525 again. This change was made to the protocol as well. Server
3526 should not violate the protocol specification anymore.
3528 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
3530 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
3531 was tested. SOCKS4 was not but should work anyway.
