3 * Added client searching by nickname hash into the IDENTIFY and
4 WHOIS commands in the server as they were clearly missing from
5 them. Affected file is silcd/command.c.
7 * Fixed a bug in private message receiving in the client library.
8 The remote ID was freed and it wasn't supposed, now it is
11 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
13 * Minor fix to the channel payload; allocate the data area, as it
14 needs to be of specific length.
16 * If the key agreement port is zero then the operating
17 system will define the bound port. Affected files are
18 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
20 * Added new function silc_channel_payload_decrypt into the file
21 lib/silccore/silcchannel.[ch].
23 * Moved the channel message etc, check from silc_packet_decrypt
24 to applications. The library calls now a generic
25 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
26 when the packet is either normal or special. This was done to
27 allow more wide range of checking that was not allowed when
28 the code was in library. Now applications can do virtually any
29 checks to the packet and return to the library the decision how
30 the packet should be processed. Affected files are
31 lib/silccore/silcpacket.[ch].
33 Added silc_server_packet_decrypt_check to the server and
34 silc_client_packet_decrypt_check to the client library.
36 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
37 to send with specified source and destination information.
39 * Channel message delivery between routers was broken after the
40 channel key distribution was fixed earlier. The channel key
41 was used be to distributed to other routers as well which is not
42 allowed by the protocol. Now this is fixed and channel keys
43 really are cell specific and the channel message delivery between
44 routers comply with the protocol specification.
46 * Fixed various commands in server to check also the global list
47 for the channel entry and not just the local list. The affected
50 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
52 * Added assert()s to buffer formatting and unformatting routines
53 to assert (if --enable-debug) when error occurs. Affected
54 file: lib/silcutil/silcbuffmt.c.
56 * Changed to auto-reconnect to check whether the remote host is
57 router and register the re-connect timeout if it is. It used
58 to check that whether we are normal server, but router must do
59 auto-reconnect with another router as well. Affected file
62 * Removed the [<key len>] option from CMODE command as the cipher
63 name decides the key length, nowadays. See the defined ciphers
64 from the protocol specification.
66 * Added [<hmac>] option to the CMODE command to define the HMAC
67 for the channel. Added SILC_CMODE_HMAC channel mode.
69 * Added [<hmac>] option for the JOIN command so that user can
70 select which HMAC is used to compute the MACs of the channel
73 * Added Hmac field to the Channel Message Payload. The integrity
74 of plaintext channel messages are now protected by computing
75 MAC of the message and attaching the MAC to the payload. The
76 MAC is encrypted. Now, it is clear that this causes some
77 overhead to the size of the packet but rationale for this is that
78 now the receiver can verify whether the channel message decrypted
79 correctly and also when private keys are set for the channel the
80 receiver can decrypt the packet with several keys and check from
81 the MAC which key decrypted the message correctly.
83 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
84 lib/silccrypt/silccipher.[ch].
86 * Added silc_hash_len to return the digest length into the
87 lib/silcrypt/silchash.[ch].
89 * Rewrote parts of Silc Channel Payload interface in the
90 lib/silccore/silcchannel.[ch]. The encode function now also
91 encrypts the packet and parse function decrypts it.
93 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
95 * Fixed a minor formatting bug in the SKE's key material processing.
96 It actually might have processed the keys wrong way resulting
99 * Redefined the mandatory HMAC algorithms and added new algorithms.
100 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
101 and hmac-md5 truncated to 96 bits. The mandatory is now
102 hmac-sha1-96. Rest are optional (including the one that used
103 to be mandatory). Rationale for this is that the truncated HMAC
104 length is sufficient from security point of view and can actually
105 make the attack against the HMAC harder. Also, the truncated
106 HMAC causes less overhead to the packets. See the RFC2104 for
109 * Added new [hmac] configuration section. The SKE used to use
110 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
111 is of course wrong. The official names that must be proposed in
112 the SKE are the ones defined in the protocol specification
113 (hmac-sha1-96 for example). The user can configure any hmac
114 using any hash function configured in the [hash] section. At
115 least, the mandatory must be configured.
117 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
119 * Added HMAC list to the SKE proposal list. It has now both
120 hash algorithm list and HMAC list. This makes the protocol
121 incompatible with previous versions. The SKE now seems to work
122 the way it is supposed to work, for the first time actually.
124 * Defined plain Hash algorithms to the protocol specification.
127 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
129 * Implemented support for key agreement packets into the server.
130 Added functions silc_server_key_agreement and
131 silc_server_send_key_agreement. Other than these functions,
132 server has nothing to do with this packet.
134 * Added support for private message key packets into the server.
135 Added functions silc_server_private_message_key and
136 silc_server_send_private_message_key.
140 * Changed the silc_[client|server]_protocol_ke_set_keys to be
141 called in the protocol's final callback instead in the END
142 protocol state. This makes a little more sense and in the same
143 time in client we can use the same protocol routines for normal
144 key exchange and to key agreement packet handling as well.
146 * Added to both client's and server's KE protocol context the
147 SilcSKEKeyMaterial pointer to save the key material. We will
148 bring the key material to the protocol's final callback by doing
149 this. The final callback must free the key material.
151 * Added SKE's packet_send callback into client's KE protocol
152 context so that the caller can choose what packet sending function
153 is used. This way we can use different packet sending when
154 doing normal SKE when doing key agreement packet handling (in
155 the key agreement packet handling we do not want to encrypt
158 * Implemented the responder side of the key agreement routines
159 in the client. The client can now bind to specified port and
160 accept incoming key negotiation. The key material is passed
161 to the application after the protocol is over.
163 * Implemented the processing of incoming Key Agreement packet
164 in the client. Added function silc_client_key_agreement to
167 * Implemented the intiator side of the key agreement routines
168 in the client. The client can now initiate key agreement with
169 another remote client. The key material is passed to the
170 application after the protocol is over.
172 * Created client_keyagr.c to include all the key agreement
175 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
176 SILC_TASK_CALLBACK except that it is not static.
178 * Created client_notify.c and moved the Notify packet handling
179 from the client.[ch] into that file.
181 * Created client_prvmsg.c and moved all private message and
182 private message key routines from the client.[ch] into that file.
184 * Create client_channel.c and moved all channel message and
185 channel private key routines from the client.[ch] into that file.
187 * Changed silc_client_get_client_by_id_resolve to resolve with
188 WHOIS command instead of IDENTIFY command, in the file
189 lib/silclient/idlist.c.
191 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Implemented the SKE's responder side to the Client library.
195 * When FAILURE is received to the protocol do not trust it
196 blindly. Register a timeout to wait whether the remote closes
197 the connection as it should do it, only after that process the
198 actual failure. This was changed to both client and server.
200 * Added client_internal.h to include some of the structures
201 there instead of client.h in lib/silcclient/.
203 * Added function silc_task_unregister_by_callback to unregister
204 timeouts by the callback function.
206 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
208 * Some "Incomplete WHOIS info" errors has been appearing on the
209 log files. Took away the entry->userinfo check from WHOIS
210 reply sending. The entry->userinfo is now " " if client did not
211 provide one. I thought this was fixed earlier but something
212 is wrong still. Let's see if the error still appears.
214 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
216 * Fixed a minor bug in the login when the channel key is
217 re-generated in the server. It used to generate the key in
218 wrong order and thus caused problems in the channel traffic.
220 * Fixed a minor bug in channel key distsribution after
221 KICK command. The key was not sent to the router even though
224 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
226 * Added silc_ske_process_key_material_data as generic routine
227 to process any key material as the SILC protocol dictates. The
228 function is used by the actual SKE library but can be used by
229 applications as well. This relates to the private message keys
230 and the channel private keys since they must be processed the
231 same way the normal SILC session keys. The protocol dictates
232 this. Affected files: lib/silcske/silcske.[ch].
234 Added also silc_ske_free_key_material to free the
235 SilcSKEKeyMaterial structure.
237 * Defined silc_cipher_set_key function to set the key for
238 cipher without using the object's method function. The affected
239 files: lib/silccrypt/silccipher.[ch].
241 * Implemented silc silc_client_add_private_message_key,
242 silc_client_add_private_message_key_ske,
243 silc_client_del_private_message_key,
244 silc_client_list_private_message_keys and
245 silc_client_free_private_message_keys functions in the
248 Added functions silc_client_send_private_message_key to send
249 the Private Message Key payload and silc_client_private_message_key
250 to handle incoming Private Message Key payload.
252 * Added Cipher field to the Private Message Key payload to set
253 the cipher to be used. If ignored, the default cipher defined
254 in the SILC protocol (aes-256-cbc) is used.
256 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
258 * Removed lib/silcclient/ops.h file.
260 Redefined parts of the SILC Client Library API. Created new
261 file silcapi.h that deprecates the ops.h file and defines the
262 published Client Library API. Defined also private message key
263 API and channel private key API into the file.
265 This is the file that the application must include from the
266 SILC Client Library. Other files need not be included by
267 the application anymore.
269 * Added new key_agreement client operation callback and also
270 defined the Key Agreement library API for the application.
272 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
274 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
275 is used by clients to request key negotiation between another
276 client in the SILC network. If the negotiation is started it
277 is performed using the SKE protocol. The result of the
278 negotiation, the secret key material, can be used for example
279 as private message key.
281 Implemented the Key Agreement payload into the files
282 lib/silccore/silauth.[ch].
284 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
286 * Redefined ciphers for the SILC protocol. Added some new ciphers
287 and defined the key lengths for the algorithms. Changed the
288 code accordingly. The default key length is now 256 bits.
290 * Fixed SKE key distribution function silc_ske_process_key_material
291 when the key length is more than 128 bits. The default key
292 length in SILC is now 256 bits.
294 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
295 to indicate unsupported algorithm.
297 * Renamed rijndael.c to aes.c and all functions as well.
299 * Fixed a long standing channel key setting bug in client library.
300 Weird that it has never surfaced before.
302 * Fixed bug in channel deletion. If the entire channel is removed
303 then it must also delete the references of the channel entry
304 from the client's channel list as the client's channel entry and
305 the channel's client entry share same memory.
307 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
309 * Implemented CONNECT and SHUTDOWN commands in the client.
311 * Implemented CLOSE command to the client.
313 * Added the function silc_idlist_find_server_by_name into the
314 files silcd/idlist.[ch].
316 Added the function silc_idlist_find_server_by_conn into the
317 files silcd/idlist.[ch].
319 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
321 * DIE command was renamed to SHUTDOWN. Updated the both code
324 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
325 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
327 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
330 * Added function silc_server_create_connection function to create
331 connection to remote router. My server implementation actually
332 does not allow router to connect to normal server (it expects
333 that normal server always initiates the connection to the router)
334 so the CONNECT command is only good for connecting to another
337 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
339 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
340 or some other client was kicked from the channel.
342 Implemented the handling of the notify type to both client
345 Implemented silc_server_send_notify_kicked to send the KICKED
346 notify. It is used to send it to the server's primary router.
348 * Implemented the KICK command into server and client.
350 * Added `query' argument to the silc_idlist_get_client function
351 to indicate whether to query the client from server or not if
354 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
355 to indicate that the client is not channel founder.
359 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
361 * Removed the rng context from SilcPacketContext structure and
362 changed that the packet routine uses the Global RNG API.
364 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
366 * Added support for quit message that client can "leave" on the
367 channel when it quits the SILC. It is ditributed inside the
368 SILC_NOTIFY_TYPE_SIGNOFF notify type.
370 Added silc_server_free_client_data that will take the
371 signoff message as argument.
373 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
375 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
377 * Updated parts of the protocol specification to keep it up
380 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
382 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
383 payloads in one packet.
385 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
386 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
387 use now the new List flag.
389 * Also deprecated the following packet types: REPLACE_ID,
390 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
392 * Added list support for Notify packet in server.
394 * Added silc_server_send_notify_channel_change to send the
395 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
396 the silc_server_send_replace_id.
398 * Added silc_server_send_notify_nick_change to send the
399 NICK_CHANGE notify type. Deprecates the function
400 silc_server_send_replace_id.
402 * Added silc_server_send_notify_join to send the JOIN notify type.
403 Deprecates the function silc_server_send_new_channel_user.
405 * Added silc_server_send_notify_leave to send LEAVE notify type.
406 Deprecates the function silc_server_send_remove_channel_user.
408 * Added silc_server_send_notify_cmode and
409 silc_server_send_notify_cumode to send CMODE and CUMODE notify
410 types. Deprecates the silc_server_send_set_mode function.
412 * Added SERVER_SIGNOFF notify type to indicate that server has
413 quit. This means that all clients on the channel from that
414 server will drop. This can be also used when netsplit happens.
416 Deprecated REMOVE_ID packet type since it is not needed anymore
419 Added silc_server_send_notify_server_signoff to send the
420 SERVER_SIGNOFF notify type. Deprecates the function
421 silc_server_send_remove_id.
423 Added also silc_server_send_notify_signoff to send the
426 * Employed the PKCS #1. It is the mandatory way to do RSA in the
427 SILC protocol from this day on. Changed the protocol
428 specification as well.
430 * Added silc_server_send_notify_topic_set to send TOPIC_SET
431 notify type. It is used between routers to notify about
432 topic changes on a channel.
434 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
437 * Partly updated the protocol specification to comply with the
438 changes now made. It is still though a bit outdated.
440 * The JOIN notify type now takes one extra argument <Channel ID>.
441 The packet used to be destined to the channel but now the
442 JOIN type may be sent as list thus it is impossible to
443 destine it to any specific channel. By adding this argument
444 it is again possible.
446 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
448 * Added CREDITS file. The CHANGES and CREDITS file will appear
449 in the distribution as well.
451 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
453 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
454 types in the server's silcd/packet_receive.c.
456 * Implemented CMODE and CUMODE to work in router environment.
458 * Fixed minor encoding and decoding buglet from the
459 lib/silccore/silcmode.c.
461 * Fixed buffer overflow from lib/silcclient/command.c in USERS
464 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
466 * Changed all SilcConfigServer* and silc_config_server* to
467 SilcServerConfig* and silc_server_config*, respectively.
470 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
472 * Associated the ID (client or server ID) to the Authentication
473 Payload to avoid any possibility of forging. Updated the
474 protocol specification and the code accordingly.
476 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
478 * The RSA key length is now save to the RsaKey context in the
479 key generation process in lib/silccrypt/rsa.c. The key length
480 is now used to figure out the maximum size of the block allowed
481 to be encrypted/signed.
483 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
484 is equivalent to the silc_mp_mp2bin but does not allocate any
487 * Changed silc_mp_mp2bin API to take length argument. If it is
488 non-zero then the buffer is allocated that large. If zero, then
489 the size is approximated using silc_mp_sizeinbase, which however
492 * Created Global RNG API which is global RNG that application can
493 initialize. After initializing, any routine anywhere in the
494 code (including library) can use RNG without allocating a new
495 RNG object. This was done to allow this sort of use of the
496 RNG in code that has no chance to allocate RNG object. All
497 applications currently allocate this and many routines in the
498 library use this. Affected file lib/silccrypt/silcrng.[ch].
500 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
501 it to use the Global RNG API.
503 * Defined Authentication Payload into protocol specification that
504 is used during SILC session to authenticate entities. It is
505 used for example by client to authenticate itself to the server
506 to obtain server operator privileges.
508 Implemented this payload into the lib/silccore/silcauth.[ch].
509 Implemented also routines for public key based authentication
510 as the new protocol specification dictates.
512 Moved definitions of different authentication methods from
513 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
515 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
516 silc_pkcs_verify and silc_pkcs_sign_with_hash and
517 silc_pkcs_verify_with_hash functions into the file
518 lib/silccrypt/silcpkcs.[ch].
520 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
522 * The client entry's userinfo pointer must be always valid.
523 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
524 will fail since it requires the userinfo. Now, the userinfo
525 is allocated as "" if actual userinfo does not exist. Actually,
526 it must exist and it is totally Ok to drop client connections
527 that does not announce the userinfo. However, we will make
528 this workaround for now.
530 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
531 to return the remote port by socket.
533 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
535 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
536 SILC_SERVER_PENDING_EXEC and added an new macro
537 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
538 data or when error occurs while processing the pending command.
540 Added new argument `destructor' into silc_server_command_pending
541 and to the SilcServerCommandPending object. This destructor is
542 now called after calling the pending callback or if error occurs
543 immediately. If error occurs the actual pending callback won't
544 be called at all - only the destructor. The destructor may be
545 NULL if destructor is not needed.
547 All this applies for client library code as well. Similar
548 changes were made there as well for the pending commands.
550 In the client, the application must now allocate the
551 SilcClientCommandContext with the silc_client_command_alloc
554 * Added reference counter to the SilcServerCommandContext. Added
555 function silc_server_command_alloc and silc_server_command_dup
558 Same type of functions added to the client library for the same
561 * Removed the cmd_ident from IDListData away since it is now
562 global for all connections. It is the command identifier used
563 in command sending and with pending commands. The affected file
566 * Added reference counter to the SilcSocketConnection objecet to
567 indicate the usage count of the object. The object won't be
568 freed untill the reference counter hits zero. Currently only
569 server uses this, and client ignores it. The client must be
570 set to use this too later. The affected files are
571 lib/silccore/silcsockconn.[ch]. Added also the function
572 silc_socket_dup to increase the reference counter.
574 This was mainly added because it is possible that the socket
575 is removed underneath of pending command or other async
576 operation. Now it won't be free'd and proper DISCONNECTING
577 flags, etc. can be set to avoid sending data to connection that
578 is not valid anymore.
580 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
581 the connection. After that it sets SILC_SET_DISCONNECTED.
582 It is, however, possible that the socket data is not still freed.
583 The silc_server_packet_process now checks that data is not
584 read or written to connection that is DISCONNECTED. The socket
585 get's freed when the reference counter hits zero.
587 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
589 * Changed the client operation API: channel_message operation's
590 `sender' is now the client entry of the sender, not the nickname
591 and the `channel' is the channel entry, not the channel name.
593 In the private_message operation the `sender' is now also the
594 client entry of the sender not the nickname.
596 Affected file is lib/silcclient/ops.h and all applications
597 using the client operations.
599 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
601 * Moved the calling of ops->connect() from connect_to_server_final
602 into receive_new_id functin since that is the point when the
603 client is actually allowed to send traffic to network. The
604 affected file is lib/silcclient/client.c.
606 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
608 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
609 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
610 (if needs broadcasting) instead of broadcasting the packets one
611 by one which would make a burst in the network traffic.
613 * Added `broadcast' argument to the functions in silcd/server.[ch]
614 silc_server_create_new_channel[_with_id] to indicate whether
615 to send New Channel packet to primary router.
617 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
619 * Added new function into the silcd/server.[ch] files:
620 silc_server_create_new_channel_with_id to create new channel with
621 already existing Channel ID.
623 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
624 lib/silccore/silcpacket.h. This packet is used t send list of
625 Set Mode payloads inside one packet. Server uses this to set
626 the modes for the channels and clients on those channels, that it
627 announced to the router when it connected to it. The protocol
628 specification has been updated accordingly.
630 * The silc_server_new_channel did not handle the packet coming
631 from normal server as it normally does not send that. However,
632 when it announces its channels it does send it. Implemented
633 the support for that.
635 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
636 into the file lib/silccore/id.h.
638 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
640 * Fixed memory leaks in the functions silc_idlist_del_client,
641 silc_idlist_del_channel and silc_idlist_del_server in the file
642 silcd/idlist.c. All of those leaked like a sieve.
644 * Fixed some small memory leaks in the client's function
645 silc_client_notify_by_server.
647 * Added functions into silcd/server.c: silc_server_announce_clients,
648 silc_server_announce_channels and silc_server_announce_server.
649 These functions are used by normal and router server to announce
650 to its primary router about clients, channels and servers (when
651 router) that we own. This is done after we've connected to the
654 These functions effectively implements the following packet types:
655 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
656 and SILC_PACKET_NEW_ID_LIST.
658 * Added new functions into the silcd/packet_receive.[ch]:
659 silc_server_new_id_list, silc_server_new_channel_list and
660 silc_server_new_channel_user_list to handle the incoming
661 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
663 * Added support of changing Channel ID in the function
664 silc_server_replace_id. If the server that announces a channel
665 to the router already exists in the router (with same name but
666 with different Channel ID), router is responsible to send
667 Replace ID packet to the server and force the server to change
668 the Channel ID to the one router has.
670 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
671 client that the Channel ID has been changed by the router. The
672 normal server sends this to the client. Client must start using
673 the new Channel ID as the channel's ID.
675 Implemented handling of this new type into lib/silcclient/client.c
676 into the function silc_client_notify_by_server.
678 * Added new function silc_idlist_replace_channel_id into the files
679 silcd/idlist.[ch] to replace the Channel ID.
681 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
683 * Call silc_server_command_identify_check always when processing
684 the IDENTIFY command in silcd/command.c
686 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
688 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
689 send keepalive packets. The packet can be sent by clients,
692 Added function silc_socket_set_heartbeat into the file
693 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
694 If not set, the heartbeat is not performed. The actual
695 heartbeat is implemented in the low level socket connection
696 library. However, application is responsible of actually
699 Added silc_server_send_heartbeat to send the actual heartbeat
700 packet into silcd/packet_send.[ch]. Server now performs
701 keepalive with all connections.
703 * Added silc_task_get_first function into lib/silcutil/silctask.c
704 to return the timeout task with shortest timeout. There was a bug
705 in task unregistration that caused problems. TODO has been
706 updated to include that task system must be rewritten.
708 * The client library will now resolve the client information when
709 receiving JOIN notify from server for client that we know but
710 have incomplete information.
712 * Rewrote parts of silc_server_remove_from_channels and
713 silc_server_remove_from_one_channel as they did not remove the
714 channel in some circumstances even though they should've.
716 * Encryption problem encountered in server:
718 The LEAVE command used to send the Channel Key packet to the
719 router immediately after generating it. However, the code
720 had earlier sent Remove Channel user packet but not immediately,
721 ie. it was put to queue. The order of packets in the router
722 was that Channel Key packet was first and Remove Channel User
723 packet was second, even though they were encrypted in the
724 reverse order. For this reason, MAC check failed. Now, this
725 is fixed by not sending the Channel Key packet immediately but
726 putting it to queue. However, this is more fundamental problem:
727 packets that are in queue should actually not be encrypted
728 because packets that are sent immediately gets encrypted
729 actually with wrong IV (and thus MAC check fails). So, packets
730 that are in queue should be encrypted when they are sent to
731 the wire and not when they put to the queue.
733 However, the problem is that the current system has not been
734 designed to work that way. Instead, the packet is encrypted
735 as soon as possible and left to the queue. The queue is then
736 just purged into wire. There won't be any fixes for this
737 any time soon. So, the current semantic for packet sending
740 o If you send packet to remote host and do not force the send
741 (the packet will be in queue) then all subsequent packets to the
742 same remote host must also be put to the queue. Only after the
743 queue has been purged is it safe again to force the packet
746 o If you send all packets immediately then it safe to send
747 any of subsequent packets through the queue, however, after
748 the first packet is put to queue then any subsequent packets
749 must also be put to the queue.
751 Follow these rules and everything works fine.
753 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
755 * Added new function silc_server_remove_clients_by_server to
756 remove all client entries from ID list when the server connection
757 is lost. In this case it is also important to invalidate all
758 client entires as they hold the invalid server entry. This
759 fixes fatal bug when server has lost connection and will reconnect
762 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
764 * Made some sanity checks to silc_server_daemonise like to check
765 whether the requested user and group actually exists.
767 * Added sanity check to SKE's silc_ske_responder_finish to check
768 that the public and private key actually is valid.
770 * Invalidate the client's nickname when receiving Replace ID
771 packet and the Client ID is being replaced. This means that the
772 server will query the nickname if someone needs it (client)
775 * Sort the ID Cache in client library when the ID Cache data
776 has changed (needs sorting).
778 * Do not allow for SILC client to create several connections to
779 several servers. The client does not support windows right now
780 and generating multiple connections causes weird behaviour.
782 Irssi-silc client does support windows and can handle several
783 connections without problems, see: www.irssi.org and SILC plugin.
785 * Fixed some places where client was added to the IDList. The
786 rule of thumb is following (in order to get everything right):
787 If the client is directly connected local client then the
788 `connection' argument must be set and `router' argument must be
789 NULL to silc_idlist_add_client function. If the client is not
790 directly connected client then the `router' argument must
791 bet set and the `connection' argument must be NULL to the
792 silc_idlist_add_client function.
794 * The funtion silc_server_packet_send_local_channel actually did
795 not check whether the client was locally connected or not. It
796 does that now. Fixed a bug related to LEAVE command.
798 * Fixed Remove Channel User payload parsing bug in server's
799 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
801 * The server's silc_server_save_channel_key now checks also the
802 global ID list for the channel as it might not be in the local
803 list. Fixed a bug related to LEAVE command.
805 * Is this the end of the [<unknown>] buglet that has been lurking
806 around for a long time? A little for loop fix in server's
807 silc_server_command_whois_parse that is used by both IDENTIFY
808 and WHOIS command. At least, this was a clear bug and a cause
809 of one type of [<unknown>] buglet.
811 * WHOIS and IDENTIFY commands call the function
812 silc_server_command_[whois/identify]_check function even if
813 we are not router server.
815 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
817 * Added --with-gmp configuration option. If set the GMP
818 is always compiled in the SILC source tree. If not set then
819 it is checked whether the system has the GMP3 installed. If
820 it has then the GMP won't be compiled (the system's headers
821 and library is used), if it doesn't have it then the GMP is
822 compiled in the SILC source tree.
824 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
826 * Changed RSA private exponent generation to what PKCS #1
827 suggests. We try to find the smallest possible d by doing
828 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
829 not security fix but optimization.
831 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
833 * Added new config entry [Identity] to fork the server and run
834 it as specific user and group. A patch from Bostik.
836 * Imported Dotconf configuration library into lib/dotconf.
837 This will be used to create the SILC configuration files later.
838 It will appear in the distsribution after this commit.
840 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
842 * A big code auditing weekend happening. Auditing code for
843 obvious mistakes, bugs and errors. Also, removing any code
846 Removed files for being obsolete:
848 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
849 inline in the file lib/silcutil/silcbuffer.h)
851 o lib/silcutil/silcbufutil.c (the header has inline versions)
853 Changed code to fix possible error conditions:
855 o The buffer formatting routines now check that the destination
856 buffer really has enough space to add the data. This applies for
857 both buffer formatting and unformatting
858 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
859 unformatting was changed to accomodate following rules:
860 XXX_*STRING_ALLOC will allocate space for the data into the pointer
861 sent to the function while XXX_*STRING will not allocate or copy
862 the data into the buffer. Instead it sets the pointer from the
863 buffer into the pointer sent as argument (XXX_*STRING used to
864 require that the pointer must be allocated already). This change
865 makes this whole thing a bit more consistent and more optimized
866 (note that the data returned in the unformatting with XXX_*STRING
867 must not be freed now). The routines return now -1 on error.
869 o Tried to find all code that use buffer_format and buffer_unformat
870 and added return value checking to prevent formatting and
871 especially unformatting errors and possible subsequent fatal
874 o Changed ske->x and ske->KEY to mallocated pointers in
875 lib/silcske/silcske.h. Fixed possible data and memory leak.
877 o Added return value checking to all *_parse* functions. Fixed
878 many memory leaks as well.
880 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
881 so that buffer overflows would not happen. All code now also
882 checks the return value as it can fail.
884 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
886 * Added reconnection support to server if the normal server looses
887 its connection to the router (for example if router is rebooted).
888 The server performs normal reconnection strategy implemented
889 to the server. Affected file silcd/server.c.
891 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
893 * Added new packet type SILC_PACKET_SET_MODE that is used to
894 distribute the information about changed modes (for clients,
895 channels and clients channel modes) to all routers in the
896 network. Updated the protocol specification accordingly.
898 Added functions into silcd/packet_send.c and
899 silcd/packet_receive.c: silc_server_send_set_mode,
900 silc_server_set_mode.
902 Added new files silcmode.[ch] into lib/silccore that implements
903 the encoding and decoding of Set Mode Payload. Added new type
904 SilcSetModePayload. Moved the definitions of different modes
905 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
907 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
909 * Oops, a little mistake in server's connection authentication
910 protocol. The protocol is not ended with FAILURE but with
911 SUCCESS if the authentication is Ok. :) Affected file is
914 * Implemented NICK_CHANGE notify handling in server in the file
915 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
916 the local clients on the channel. After the changing nickname
917 in router environment snhould work and the [<unknown>] nickname
918 should appear no more.
920 The silc_server_replace_id function that receives the Replace ID
921 payload now sends the NICK_CHANGE notify type also in the file
922 silcd/packet_receive.c
924 * Changed WHOIS and IDENTIFY command to support the maximum amount
925 of arguments defined in protocol specs (3328 arguments). This
926 fixed a bug that caused problems when there were more than three
929 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
931 * Added extra parameter, command identifier, to the
932 silc_client_send_command so that explicit command identifier
935 Changed that ID list routines uses specific command identifier
936 when sending WHOIS/IDENTIFY requests to the server so that they
937 can be identified when the reply comes back.
939 Affected files lib/silcclient/command.[ch],
940 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
942 * Added `sender' argument to silc_server_packet_send_to_channel
943 to indicaet the sender who originally sent the packet to us
944 that we are now re-sending. Ignored if NULL. Affected file
945 silcd/packet_send.[ch].
947 * Added some server statistics support in silcd/server_internal.h
948 SilcServerStatistics structure and around the server code. Also
949 send some nice statistics information when client is connecting
952 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
954 * Fixed channel ID decoding in server's JOIN command reply in
955 silcd/command_reply.c
957 * Fixed braodcasting of replace ID payload to not to send it if
958 we are standalone server in silcd/packet_receive.c.
960 * Fixed all channel message sending routines to not to send
961 packets to clients that has router set, since they are routed
962 separately in the same function earlier. Affects file
963 silcd/packet_send.c and all channel packet sending functions.
965 * In USERS reply, res_argv[i] are not allocated, the table
966 is allocated. Thus changed that free the table, not its
969 * In server's whois_check and identify_check if the client is
970 locally connected do not send any WHOIS commands - they are not
973 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
975 * Fixed some minor bugs in client when sending WHOIS command. The
976 arguments was in wrong order.
978 * Removed statis function add_to_channel from server in
979 silcd/command.c that was previously used with the joining but
982 * Tested USERS command in router environment successfully with two
983 routers, two servers and two clients.
985 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
987 * Reorganized the USERS command and command reply in client library
988 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
989 When the command is given by user we register a pending command
990 callback that will reprocess the command after the reply has been
991 received from the server. When reprocessing the packet we then
992 display the information. Thus, the USERS information is displayed
993 now in the command callback instead of in the command reply
994 callback. The processing of the command is same as previously
995 when server has sent the command reply in the JOINing process.
997 * Added to USERS command in silcd/command_reply.c to join the client,
998 we didn't use to know about, to the channel after we've created
999 a client entry for it. Also, for clienet we did know already still
1000 check whether it is on the channel or not and add it if not.
1002 * Removed silc_server_command_join_notify as the function and its
1005 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1007 * Changed the client's pending command handling to the same as the
1008 server's pending command handling. It is also now possible to
1009 execute command reply functions from other command reply
1010 function as the function callbacks for commands and command
1011 replies are one and same. The pending commands are not static
1012 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1013 in client connection context. Thus, pending commands are server
1014 connection specific as it is convenient.
1016 Changed the function silc_client_command_pending and
1017 silc_client_command_pending_del and added new function
1018 silc_client_command_pending_check. Removed the
1019 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1022 * Added cmd_ident, current command identifier, to the client
1023 connection context in lib/silcclient/client.h to keep track on
1024 command identifiers used in command sending. Client's command reply
1025 function handling now supports the mandatory command identifiers.
1027 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1028 funtions in client to fully support pending command callbacks.
1030 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1031 as one of the arguments to the application in the command reply
1034 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1035 before first releasing SILC but came back. Now it is removed again
1036 and should come back nomore. The FORWARDED flag was used only
1037 by the JOINing procedure by forwarding the command packet to router.
1038 Now, the JOINing procedure has been changed to more generic (due
1039 to various router environment issues) and FORWARDED is not needed
1040 anymore for anything. The protocol specification is yet to be
1043 Now, removed silc_server_packet_forward from server and the flag
1044 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1046 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1048 * Renamed NAMES command to USERS command. The NAMES was named that
1049 due to historical reasons. Now it is renamed. Also, rewrote
1050 parts of the USERS command. The nickname list is not sent anymore
1051 by the server. Only Client ID and mode lists are sent in the USERS
1052 command. Changed this also to the protocol specification.
1054 The client now resolves the names and stuff after it receives
1055 the USERS list from the server when joining to the channel.
1057 * WHOIS and IDENTIFY commands has been changed to support multiple
1058 Client ID's per command. One can now search for multiple users
1059 in the network by sending only one WHOIS or IDENTIFY command.
1060 Changed the code and the protocol specifications.
1062 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1063 uses silc_server_command_whois_parse to parse the request. */
1065 * If normal server, do not parse the WHOIS and IDENTIFY requests
1066 before sending it to the router. Saves some time.
1068 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1070 * Fixed JOIN command on client library. Wrong number of arguments
1071 used to crash the client.
1073 * Added silc_server_channel_has_global function to check whether
1074 channel has global users or not.
1076 * Added silc_server_channel_has_local function to check whether channel
1077 has locally connected clients on the channel.
1079 * The silc_server_remove_from_one_channel now checks whether the
1080 channel has global users or not after given client was removed from
1081 the channel. It also checks whether the channel has local clients
1082 on the channel anymore. If it does not have then the channel entry
1083 is removed as it is not needed anymore.
1085 * The silc_server_notify now checks on JOIN notify whether the joining
1086 client is one of locally connected or global. If it is global then
1087 the channel has now global users on the channel and that is marked
1088 to the channel entry. Also, it now saves the global client to
1089 global list who is joining and JOINs it to the channel. This is
1090 for normal server, that is.
1092 Changed silc_server_send_notify_on_channel,
1093 silc_server_packet_relay_to_channel and
1094 silc_server_packet_send_to_channel check if we are normal server
1095 and client has router set (ie. global client) do not send the
1096 message to that client, as it is already routed to our router.
1098 * Implemented LEAVE notify type handling in silc_server_notify
1101 * Tested LEAVE command in router environment successfully. Tested
1102 with two routers, two servers and two clients.
1106 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1108 * Implemented SIGNOFF notify type handling in silc_server_notify
1111 * silc_server_remove_id now removes the client entry from all channels
1112 it has joined and thusly sends SIGNOFF notify type.
1114 * Rewrote the NAMES list generation in server by removing two excess
1115 loops. The lists are created now inside one loop.
1117 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1119 * silc_server_remove_channel_user checks now also global list
1120 for channel and client.
1122 * silc_server_new_channel_user checks now both local and global
1123 list for channel and client. Fixed a bug in client id decoding.
1124 Used to decode wrong buffer.
1126 * silc_server_channel_message checks now both local and global
1127 list for channel entry.
1129 * Tested channel joining (hence JOIN) in router environment
1130 successfully. Tested with two routers, two servers and two
1133 * Tested channel message sending in router environment successfully.
1135 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1137 * Added silc_server_save_channel_key into server.[ch] to save the
1138 received channel key in Channel Key payload processing. It is
1139 also used in JOIN command reply handling.
1141 Equivalent function silc_client_save_channel_key added into
1142 client.[ch] into client library.
1144 * Changed JOIN command reply to send information whether the channel
1145 was created or not (is existing already) and the channel key
1146 payload. Changed protocol specs accordingly.
1148 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1149 the request was sent by ID and not by nickname. Crashed on
1152 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1154 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1155 now correctly save the received data.
1157 * silc_server_free_sock_user_data now notifies routers in the
1158 network about entities leaving the network.
1160 At the same time implemented functions silc_server_remove_id
1161 and silc_server_send_remove_id to receive and send REMOVE_ID
1162 packets. The packet is used to notify routers in the network
1163 about leaving entities. The ID removed will become invalid in
1166 * Added function silc_idlist_del_server into server. Removes and
1167 free's server entry from ID list.
1169 * silc_server_private_message function now checks, if we are router,
1170 that the destination ID really is valid ID, naturally.
1172 * In router when NEW_ID packet is received (for new client) the
1173 hash of the Client ID is saved in the ID Cache but the
1174 client->nickname is set to NULL, instead of putting the hash
1177 IDENTIFY command now also checks that client->nickname must be
1178 valid. If it is not if will request the data from the server who
1179 owns the client. Added new function
1180 silc_server_command_identify_check.
1182 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1183 to set the command to already allocated Command Payload.
1185 * Tested private message sending in router environment with two
1186 routers, two servers and two clients. Fixed minor bugs and now
1189 * Fixed segfault from client's NAMES command. Used to crash if
1192 * Forwarded packets must not be routed even if it is not destined
1193 to the receiver. Changed server code comply with this.
1195 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1197 * Added `require_reverse_mapping' boolean value to ServerParams
1198 structure. If TRUE (not default) the server will require that
1199 the connecting host has fully qualified domain name.
1201 If the reverse mapping is not required and hostname could not be
1202 found the IP address is used as hostname.
1204 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1206 * Implemented version string checking to both client and server.
1207 The check is incomplete currently due to the abnormal version
1208 strings used in development version of SILC.
1210 * Changed all command functions in server to use the new
1213 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1215 * Changed char *data to unsigned char *data in ID Cache system to
1216 support binary data as ID Cache data. Changed code to support
1217 binary data in lib/silccore/idcache.c.
1219 * Renamed silc_server_packet_relay_command_reply to
1220 silc_server_command_reply as it is normal packet receiving
1221 function. Rewrote the function to accept command replys for
1222 servers and not only for clients.
1224 * Mark remote router always as registered server if we are connecting
1225 to it. Otherwise, commands sent by the router to us are ignored.
1227 * All ID List find routines now returns the ID Cache Entry pointer
1228 as well if requested.
1230 * WHOIS command works now in router environment, tested with two
1231 routers, two servers and two clients.
1233 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1234 in router environment (as it is almost equivalent to WHOIS) but
1235 hasn't been tested thoroughly. Added new functions:
1237 silc_server_command_identify_parse
1238 silc_server_command_identify_send_reply
1239 silc_server_command_identify_from_client
1240 silc_server_command_identify_from_server
1242 * Disabled route cache adding because adding two different ID's with
1243 same IP replaces the old cache entry thus giving wrong route.
1244 The entry->router->connection is always the fastest route anyway
1245 so route cache may not be needed. Of course, new routes maybe
1246 established after receiving the ID when the entry->router->connection
1247 might not be anymore the most optimal.
1249 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1251 * Add route cache for received ID for fast routing.
1253 * Added silc_server_packet_route to route received packet on router
1254 that is not destined to us.
1256 * Renamed silc_server_get_route to silc_server_route_get.
1258 * Added id_string and id_string_len fields into SilcServer to
1259 include encoded ServerID for fast comparing without excess
1260 encoding of the ID's.
1262 * Cleaned up WHOIS command on server side. Added following static
1265 silc_server_command_whois_parse
1266 silc_server_command_whois_check
1267 silc_server_command_whois_send_reply
1268 silc_server_command_whois_from_client
1269 silc_server_command_whois_from_server
1271 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1272 arguments in command replies. All command functions should be
1273 updated to use this macro.
1275 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1277 * Minor typo fixes on command reply handling on server.
1279 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1281 * Added silc_server_command_add_to_channel internal routine to add
1282 the client to the channel after router has created the channel and
1283 sent command reply to the server.
1285 * Added generic silc_server_send_command to send any command from
1288 * Use static buffer with ID rendering instead of duplicating data.
1290 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1292 * Fixed a channel user mode bug when joining to a channel server gave
1293 everybody channel founder rights, oops.
1295 * We mark ourselves as the router of the incoming server connection
1296 if we are router ourselves. This way we can check in some packet
1297 sending functions whether it is locally connected server. For
1298 incoming router connections we put NULL.
1300 * For router sending packets locally means now always sending the
1301 packet cell wide; to local clients and local servers. For normal
1302 server sending packet locally means sending it to only local
1305 * Fixed the JOIN command to really work in router environment. If the
1306 channel is created it is always created by the router. Router is
1307 also responsible of making the initial joining to the channel,
1308 sending JOIN notify to the sending server and distributing
1309 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1310 does not exist server doesn't do anything else but forward the
1311 command to the router which performs everything.
1313 * Added silc_server_send_channel_key function to send the Channel Key
1316 * Added silc_server_create_channel_key to create new channel key. The
1317 channel key is now re-generated everytime someone joins or leaves
1318 a channel, as protocol dictates. Note: channel->key_len is the
1321 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1323 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1324 packet_receive.[ch] to separate packet sending and receiving
1325 routines. The server.[ch] now includes everything else including
1326 actual packet processing (writing and reading data) and other
1329 Renamed silc_server_private_message_send_internal to
1330 silc_server_send_private_message. The routine is still though
1331 used only to relay private messages as server does not send
1332 private messages itself.
1334 Renamed silc_server_new_channel to silc_server_create_new_channel
1335 and added new function sicl_server_new_channel that handles the
1336 incoming New Channel packet. Added also new sending function
1337 silc_server_send_new_channel to send New Channel Payload.
1339 * Added new function silc_server_notify to process incoming notify
1340 packet to the server/router. Server may then relay the notify
1341 to clients if needed.
1343 * Added new function silc_server_new_channel_user to process incoming
1344 New Channel User packet. Router will redistribute the packet and
1345 send JOIN notify to its local clients and locally connected servers
1346 if needed. Normal server will send JOIN notify to its local client
1347 on same channel when received this packet. Added also corresponding
1348 sending function silc_server_send_new_channel_user to sent the
1351 * Added boolean route argument to send_notif_to_channel and
1352 packet_send_to_channel functions to attempt to route the packet
1353 if it is TRUE and send only locally if it is FALSE.
1355 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1357 * silc_server_replace_id now broadcasts the received replace ID
1358 packet if it is not broadcast packet already. The router must
1359 broadcast to inform other routers about changed ID.
1361 * Added backpointer to server's router into SilcServer context in
1362 silcd/server_internal.h.
1364 * Fixed silc_server_packet_broadcast to send correct broadcast
1367 * The channel key is now distributed to the local client as soon
1368 as it is received from the router (in router environment) so that
1369 no other packet may be sent for the channel until client has
1372 * silc_server_remove_channel_user now broadcasts the received
1373 Remove Channel User packet if it is not broadcast packet already.
1374 The router must broadcast to inform other routers about removed
1377 * Added users field into SilcPacketContext that is a reference count
1378 of the context. One can increase the reference count by calling
1379 silc_packet_context_dup which is now changed to just increase the
1380 reference count instead of duplicating the data. The reference
1381 count is decresed by calling silc_packet_context_free that will
1382 free the data after the reference count hits zero.
1384 For now on the packet context and everything allocated into it
1385 (including the raw packet from network) must be freed by calling
1386 the new silc_packet_context_free function. Added also new function
1387 silc_packet_context_alloc that must be used now to allocate the
1388 context. This also means that if a routine is asynchronous from
1389 silc_[client/server]_packet_parse_type the packet context must
1390 be duplicated by calling silc_packet_context_dup. Otherwise it
1391 gets free'd after silc_[client/server]_packet_parse_type returns.
1392 Also, one must remember that if packet is duplicated then its
1393 reference count must be decresed by calling the free function as
1394 many times as it was duplicated.
1396 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1397 from both client and server.
1399 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1401 * Made joining to a channel working in router environment.
1403 * Cleaned up JOIN command on server side and create function
1404 silc_server_command_join_channel internal routine to make the
1407 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1409 * Changed silc_command_pending list to SilcDList. Also, added
1410 `ident' field to SilcServerCommandPending structure to identify
1411 the reply and to call correct callback.
1413 Added silc_server_command_pending_check function to replace the
1414 corresnponding macro. The silc_command_pending list is not
1417 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1418 to set identifier to previously allocated Command Payload. It
1419 is used to set identifier for command when resending Command
1422 * Added silc_command_payload_encode_payload to encode Command
1423 Payload buffer from SilcCommandPayload structure.
1425 * Added silc_argument_payload_encode_payload to encode Argument
1426 payload buffer from SilcArgumentPayload structure.
1428 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1430 * Changed WHOIS command to support router connection on server side.
1431 The whois request is always sent to router unless the server is
1432 standalone server. After server has received the reply from the
1433 router will it send the reply to the client.
1435 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1436 broadcast received broadcast packet. The function is used only
1437 by router. The broadcast packet is always sent to the router's
1440 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1441 render given ID to printable string, for log files for example.
1443 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1445 * Made basic router to router connections working. At least they
1446 can now connect to each other but nothing really works the way
1447 they are supposed - yet.
1449 * Added new initiator token to RouterConnection configuration
1450 file in silcd/serverconfig.[ch]. It is used to tell whether we
1451 are the initiator to the remote router or whether we'll expect
1452 the other end to connect.
1454 * Moved registering of listener task to silc_server_init, hence
1455 the server starts listenning as soon as it is run, even if it
1456 does not have connections to other routers. Let's see how well
1459 * Changed default connection retry timeouts for more suitable in
1462 * Removed cipher and such arguments from silc_idlist_add_client
1463 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1464 Added new function silc_idlist_add_data to add the keys and stuff
1467 * Added SilcIDListData structure and added it to SilcClientEntry
1468 and SilcServerEntry as their first field in the structure. This
1469 way we can explicitly cast the ID entries to the SilcIDListData
1470 structure and get common data for the entries. In past, we had
1471 to first check what type of connection it is and then cast it to
1472 correct ID entry type. Now, we can directly cast the opaque
1473 pointer to the SilcIDListData (no matter what ID entry it actually
1474 is) and get the data needed.
1476 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1478 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1479 in some circumstances even if threre were timeout tasks, though not
1480 IO tasks, but tasks anyway. Now fixed.
1482 * Defined SilcServerConnection structure to hold connection specific
1483 stuff about directly connected servers and routers. The definition
1484 is currently in silcd/server_internal.h. I thought about having
1485 a bit more important role fro this struct but for now it is used
1486 only when connecting to other server (or router actually).
1488 * Added connecting retry support in server when connecting to
1489 router(s). The retry feature implement exponential backoff
1490 algorithm. Also, added SilcServerParams structure to hold default
1491 parameters for server. For now, it include these retry settings
1492 and are hard coded. After server is moded to be as Silc Server
1493 Library this structure will be more important.
1495 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1497 * Changed client librarys channel->clients table to SilcList and
1498 changed code accordingly.
1500 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1502 * Changed client's channel table to SilcList and changed code
1503 accordingly. Also changed SilcChannelClientEntry to include back-
1504 pointer to the channel so that client entry can use that structure
1505 as list as well and we have fast cross-reference to the channel.
1506 This change dramatically decreased the complexity of channel
1507 handling with client entry and vice versa (removed one extra
1508 loop when searching for channel entry from many functions).
1510 * Changed server->sim from table to SilcDList and changed code
1513 * NAMES command can now be used from user interface. It will show
1514 the user list on the channel, neatly.
1516 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1517 Code now saves realname of the user if it becomes available.
1519 * Renamed configure.in to configure.in.pre and made ./prepare
1520 script to automatically add correct version string to
1521 configure.in which it creates from configure.in.pre.
1523 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1525 * NAMES command reply now shows users mode with the nickname when
1528 * Moved silc_client_ch[u]mode[_char] functions from
1529 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1530 place sucks, they are utility functions and should be in some
1533 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1535 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1538 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1542 * Added TRQ (efficient deque and list library) into lib/trq. This is
1543 a very good list library that is currently used in the SILC. Defined
1544 SilcList API over the library because I didn't like the API very
1545 much. See lib/trq/silclist.h for the API and examples of how to
1546 use the API. Fixed various places in the code to use the new
1547 SilcList API. The SilcList is meant for lists that has a structure
1548 already defined as a list. It is not suitable to add just some
1549 context to the list (in TRQ, the context is the list actually).
1551 So, I defined SilcDList that can be used for the purpose where
1552 predefined list structure does not exit. This can be used as
1553 such list. Now some context just can be added to the SilcDList.
1554 Currently this list is not used in the SILC just yet, though there
1555 are a lot places where this can replace dynamically allocated
1556 tables and I will fix these places, later, to use SilcDList.
1557 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1558 and use TRQ internally).
1560 Also fixed some annoying warning messages that the original TRQ
1561 code generated. Also minor changes to TRQ's Makefile.in.
1563 * Added support for querying by Client ID to both WHOIS and
1564 IDENTIFY commands into server, as required by the protocol.
1566 * Removed method function pointers from SilcBuffer structure. They
1567 weren't used to anything and just increased the context size for
1568 no good reason. This change also made silc_buffer_alloc and
1569 silc_buffer_free functions inline functions.
1571 * Disabled command flooding detection support until it's fixed so
1572 that it accepts commands in but does not execute them more than once
1575 * Added silc_net_localhost(), to return local hostname, into
1576 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1577 that must be initialized before calling silc_client_init.
1579 * Added new function: silc_server_send_notify_on_channels to send
1580 notify messages to all channels client has joined. It is assured
1581 that the message is sent only once per client.
1583 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1584 lib/silcutil/silcutil.[ch] as silc_format function. The new
1585 function is generic and is used by server as well, not only by
1586 the logging routines.
1588 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1589 the provided version string was not acceptable. Added new function:
1590 silc_ske_check_version into lib/silcske/silcske.h. The function
1591 must be implemented by the application (client or server) and it
1592 does not reside in the SKE library. The function checks the version
1593 string remote end sent.
1595 * Added back pointers (to opaque context and to SilcSocketConnection)
1596 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1598 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1599 duplicate packet context structure.
1601 * Changed `notify' client operation to send same arguments as client
1602 receives from server except for ID's. ID's are mapped to correct
1603 ID entry and that is returned. Also, if channel entry is not sent
1604 by server but the notify is for channel the channel entry is sent
1605 to application (otherwise application doesn't know that it is for
1606 channel (library gets it from packet's Destination ID)).
1608 * Added silc_client_remove_from_channels into client library to
1609 remove a client from all channels it has joined to. Used when
1610 received SIGNOFF notify from server. Added also new function
1611 silc_client_replace_from_channels to replace old ID entry with
1612 new ID entry on all channels. Used when received NICK_CHANGE
1615 * Fixed ID Cache list handling in silc_idlist_get_client in
1616 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1617 to get (or query) client by ID.
1619 * Updated TODO list.
1621 * Added connection authentication status message defined by the
1622 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1623 support for these into the code in client and server side.
1625 * Added generic function silc_client_send_command to send any command
1626 with variable argument list. Application should use this function
1627 to send commands if the command functions provided by the library
1628 does not suite for the application's user interface needs.
1630 * Added new `failure' client operation. Application is notified about
1631 received failure packet if client is executing a protocol. In this
1632 case the protocol's execution has failed.
1634 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1635 is required by the protocol.
1637 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1638 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1641 * Added status flag to SilcSKE object to indicate realtime status
1642 of the SKE protocol.
1644 * Application receives now exactly same command reply arguments as
1645 the library receives from server. However, if ID is received the
1646 corresponding ID entry is returned to the application (eg. Client
1647 ID is mapped to correct SilcClientEntry entry and that is returned).
1648 Changed command_reply client operation due to this change.
1650 * Changed all ID's in commands and in command replys as ID Payloads.
1651 Change affected both client and server side codes.
1653 All ID's sent in SILC network (with execption of ID's in SILC
1654 Packet header) are sent in ID Payload to support variable length
1657 * Server now notifies nick changes and notifies all clients on
1658 the channels about the new nickname (about the new Client ID,
1661 * Implemented CMODE command to change channel modes. Supports all
1662 channel modes defined by the protocol specs except ban and invite
1663 lists. (Also, private channel key mode is supported but support for
1664 setting private channel key in client is missing, thus, this mode
1665 has no effect on client side (except that server requires that the
1666 client uses private channel key and normal channel traffic does not
1669 Also, invite mode works per se, but INVITE command does not work
1670 yet correctly, so you can set channel as invite only channel but
1671 inviting clients to the channel does not work (it is yet to be
1672 thought what's the best way to do it).
1674 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1675 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1676 Implemented CUMODE command to change user's mode on the channel.
1677 Supports all modes defined by the protocol specs.
1679 * Added NAMES command reply to return users modes on the channel.
1681 * Removed unnecessary and slow ciphers from lib/silccrypt.
1683 * Set SO_KEEPALIVE option to connection sockets by default.
1685 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1687 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1688 redefined the Notify Payload into protocol specs.
1690 * Added silc_id_payload_parse_id to get ID directly from raw
1693 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1695 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1696 accept searching by Client ID as well.
1698 * Added support for LEAVE and SIGNOFF notify types in client library.
1700 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1701 to parse ID Payload from raw data.
1703 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1705 * Added flags parameter into silc_ske_assemble_security_properties
1706 function in lib/silcske/silcske.[ch].
1708 * Changed notify client operation to fit better for notify messages
1709 sent by server. The notify payload received from server is now
1710 passed to the application (after parsing it to SilcNotifyPayload).
1711 It is application's responsibility to retrieve the arguments
1712 from the payload and show the message the way it wants. The message
1713 sent by server is implementation specific.
1715 * Changed public keys to comply with the protocol specification.
1716 Old public keys are not supported anymore and are not compatible.
1718 * Removed nickname from Channel Payload as the latest draft removed
1719 it. The client must resolve the nickname from the NAMES command
1720 reply received when it joined the channel.
1722 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1724 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1726 * Fixed some errors in protocol specification drafts.
1728 * Created lib/silccore/silcnotify.c to implement Notify Payload
1729 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1730 generic payloads described by protocol specifications. The file
1731 includes implementations for ID Payload and Argument Payload.
1733 * Changed Command Payload implementation to use the new Argument
1734 Payload. Changed command_xxxx_payload to command_payload_xxxx
1735 to comply with SILC coding conventions.
1737 * Added suppport for Argument Payload handling in Notify Payload
1738 implementation as protocol requires it. Added the new support
1739 into server and client lib as well.
1741 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1743 * Added support for multiple nicknames on same channel. [n] is
1744 added locally to the nickname if there are more than one same
1745 nicknames on the channel.
1747 * Server now sends all nicknames that matched WHOIS request.
1748 Client also shows the list received from server.
1750 * Added TOPIC command to client side. User can now set and show
1751 current topic on channel.
1753 * Added MOTD command to client and server. Also, server sends the
1754 motd when client connects to the server.
1756 * Changed version strings to comply ISO 8601.
1758 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1760 * Fixed protocol error handling in client library. It should now
1761 cope even if the SKE fails for some reason.
1763 * Made new protocol specification drafts for submitting to IETF.
1765 * Implemented TOPIC command to server in silcd/command.c.
1767 * Added two new notify types into lib/silccore/silcnotify.h:
1768 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1769 notify nickname change and topic setting/change on a channel.
1771 * API change of command_reply operation in client library. The
1772 application gets now the status type received from server as well.
1774 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1776 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1778 * Cras fixed and optimized the packet handling even further and
1779 it should work now. Minor change to the prototype of function
1780 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1782 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1784 * Added new function into lib/silcutil/silcschedule.[ch]:
1785 silc_schedule_with_fd to select() a specified fd. The function
1786 returns after timeout expires or data arrives or goes. The
1787 function is used by packet routines to wait that all data is
1788 received from network.
1790 * Fixed data reading from network in lib/silccore/silcpacket.c.
1791 The code now assures that all data is read from the fd and then
1792 continues packet processing. This was a bug fix since the code
1793 used to drop some data in some circumstances.
1795 * Added new function into lib/silcclient/client.[ch]:
1796 silc_client_start_key_exchange to start key exchange after
1797 connection has been established to server. The code internally
1798 now uses this funtion but its main purpose was to provide it
1799 for applications that perform their own connecting. After
1800 application has created a connection it merely calls this
1801 function to start the key exchange between client and server.
1802 The library takes care of everything else after that.
1804 Updated also lib/silcclient/README to explain the usage of
1807 * Do not send to application information that connection has
1808 been established. Application gets notified it by connect
1811 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1813 * Applied cras's patch to add silc_schedule_one function. The
1814 function runs scheduler once and returns.
1816 * Fixed the scheduler after cras messed it up. The timeout
1817 handling works now as it's supposed to work.
1819 * Added into lib/silccore/ silcnotify.h to include notify
1820 message types support. Changed silc_server_send_notify*
1821 functions, in server.[ch], to support those new notify types.
1822 Added the support for the notify types into client library,
1823 as well. Added new notify client operation into ops.h in
1826 * Changed silc_server_packet_send_to_channel to send normal
1827 packets instead of just channel message packets. The function
1828 is now used to send the notify packets to channels. It is not
1829 used to send channel message packets anymore, as server never
1832 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1833 va_arg()s as it seems to require it nowadays. I guess, if SILC
1834 is compiled with older va_arg() the new code should work anyway.
1836 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1838 * Splitted core library. Core library (lib/silccore) includes
1839 now only SILC protocol specific core (and common) components.
1840 Created new utility library (lib/silcutil) that includes more
1841 generic purpose stuff. The stuff for util library was taken
1842 from the old core library. This was minor and easy split.
1844 * Created SILC Client Library (lib/silcclient) that includes
1845 implementation of the SILC client without user interface. This
1846 was major move from silc/ directory. The code has been changed
1847 so that it is transparent towards the user interface. The
1848 silc/ directory includes now the same user interface as before
1849 and it uses the new client library. Read lib/silcclient/README.
1850 Basicly, the client library performs everything else related
1851 to SILC except user interface handling. Also, configuration
1852 files are considered to be part of user interface and library
1853 does not handle them.
1855 This change also changed a lot of structures, function naming etc.
1856 Most important change was that SilcClientWindow object was
1857 renamed to SilcClientConnection in the client library. Created
1858 also new file lib/silcclient/ops.h. Also added new files
1859 silc/local_command.[ch] and silc/client_ops.[ch].
1861 All these changes were made to make it easier for user interface
1862 designers to create what ever user interface for the SILC client
1865 It is also expected that the server will be moved to lib
1866 directory as well and SILC Server Library will be created;
1867 sometimes in the future.
1869 * Removed Local commands from lib/silccore/silccommand.h as
1870 they are application specific and new client library does not
1871 handle any of those anymore.
1873 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1874 old client implementation in silc/.
1876 * Added support for callback functions in SILC_LOG_* macros.
1877 Application can now set its own callbacks that will be called
1878 instead of using the default functions that will always print
1879 the debug messages to stderr (or stdout). Also, debugging can
1880 now be disabled by setting silc_debug to FALSE and re-enabled by
1881 setting it to TRUE. Note, that logging will still work even
1882 if debugging is disabled.
1884 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1885 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1886 silc_log_reset_debug_callbacks.
1888 * To enable debugging in silc client one must give now -d
1889 option on command line.
1891 * Changed silc_schedule_init to automatically allocate task queues
1892 if they are not allocated before calling it.
1894 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1896 * Added GMP 3.1 into math library.
1898 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1900 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1901 a channel in SILC network. The packet is used by servers and
1902 routers to notify other routers that user has left a channel.
1903 This little feature was missing until now. Added the feature
1904 to protocol specification as well.
1906 Added functions: silc_server_send_remove_channel_user and
1907 silc_server_remove_channel_user into server.[ch].
1909 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1910 lib/silccore/silcpacket.h. However, they are not implemented
1913 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1915 * Fixed joining to a channel and sending channel messages
1916 between server and router. The channel message sending should
1917 now work inside a cell.
1919 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1921 * Fixed the private message sending between server and router.
1922 The private message sending should now work inside a cell.
1924 * Added silc_server_replace_id into server.[ch] to replace
1925 existing ID in the SILC network.
1927 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1928 and silc_idlist_replace_server_id into idlist.[ch] in server.
1930 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1932 * Fixed the server to server connections. Server can again now
1933 connect to router. Router to router connections probably does
1936 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1938 * Added dynamic protocol registering support. Now protocols can
1939 registered and unregistered on the fly. Patch by cras.
1941 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1943 * Added lib/contrib directory to hold routines that some platforms
1944 don't have but are needed by SILC.
1946 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1947 into lin/contrib to provide getopt() and getopt_long() for
1948 those who don't have it.
1950 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1952 * Added AWAY command to client. When away message is set and
1953 client receives a private message packet the client automatically
1954 replies to the sender with the away message.
1956 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1957 bug seemed to be the cause of recent problems when compiling
1960 * Added version detection support to SKE protocol specification
1961 and added the new changes to the SKE implementation as well.
1962 There were other minor changes in the SKE protocol as well.
1964 Many changes in lib/silcske/silcske.[ch] and in
1965 lib/silcske/payload.[ch].
1967 * Added ^U functionality, clear input line. Patch from cras.
1969 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1971 * Mainly small bugfixes on core library. Fixed some debugging
1972 logging and buffer overflow in silclog.c.
1974 * Updated config.sub and config.guess on the distribution tree.
1976 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1978 * Added command lagging support in server. Client may execute
1979 commands now only once in two seconds.
1981 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1983 * Optimized packet reception. MAC computation and checking is now
1984 also more optimized. A lot previously duplicated code is now
1985 used as generic by both client and server.
1987 * Fixed key pair generation in clientutil.c
1989 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1991 * Added into lib/silccore/silcbufutil.[ch] new function;
1992 silc_buffer_realloc.
1994 * Moved generic packet sending/encryption functions to
1995 lib/silccore/silcpacket.[ch] from client and server. Some
1996 rewriting of the functions.
1998 * Moved all generic packet reception/decryption functions to
1999 lib/silccore/silcpacket.[ch] from client and server. The
2000 packet processing is now much cleaner in both client and server.
2001 These were major changes in both client and server.
2003 * Created many common functions in server to do packet sending.
2004 Previously code were duplicated a lot, this has been removed
2007 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2009 * Rewrote major parts of the ID cache system. Don't know
2010 whether it is better now or not but at least the API is more
2013 * Major rewrite on ID cache stuff on client because of the ID
2014 cache API changes. Added idlist.c to client.
2016 * Also major rewrite on ID cache stuff on server as well.
2017 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2018 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2019 in hand, instead they are all put into the ID cache system now.
2020 All server_idlist_* routines uses ID cache now instead of
2021 traversing its own lists (those lists does not exist anymore).
2022 SilcIDList though still exists. Also, SilcXXXEntry's are
2025 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2027 * Finally made the SKE implementation compliant to the protocol
2028 specification. All mp integers are now binary encoded as
2029 opposed being HEX encoded.
2031 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2034 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2035 functions: silc_[encode/decode]_pem. Also added function
2036 silc_encode_pem_file to PEM encode with newlines ('\n') for
2039 * SILC public keys are now encoded either PEM or binary. Same
2040 option is for private keys as well. By default private keys
2041 are binary encoded and public keys PEM encoded. Silly HEX
2042 encoding were removed.
2044 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2045 function to create fingerprints.
2047 * Fixed a bug in SHA1; does not change the original data anymore.
2049 * Partly implemented INFO command on client and server side.
2050 Fixed CLEAR command. Changes to SERVER command; show current
2051 server(s) when giving command without arguments. Added
2052 VERSION command to client.
2054 * Added check to server that unregistered connections cannot
2055 execute commands (unless it is specificly allowed).
2057 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2059 * Fixed screen refresh.
2061 * Fixed channel joining bug from client. On some circumstances
2062 client tried to join to a channel it had already joined.
2064 * Added public key verification process into client's protocol.c.
2065 The client now verifies the public key from user and saves
2066 it into ~./silc/serverkeys/ directory.
2068 Added into: clientutil.[ch]: silc_client_verify_server_key.
2070 * Changed SKE protocol's silc_ske_initiator_finish function
2071 to accept callback function that verifies the received public
2072 key. Removed old silc_ske_verify_public_key function.
2074 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2076 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2077 silc_pkcs_private_key[_data]_set.
2079 * Made the password and public authentication more cleaner in
2080 server's protocol.c.
2082 * Removed historic and obsolete protocol `channel_auth' from
2083 both client and server.
2085 * Removed wrong way of sending command status messages from
2086 server to client in server's command.c. The old way violated
2087 protocol specification.
2089 Changes to silccore/silccommand.[ch]: removed
2090 silc_command_encode_status_payload -> not needed anymore,
2091 changed silc_command_encode_payload_va to accept extra
2092 argument on variable argument list. The argument type must
2093 now be provided to the function. Also, added new function:
2094 silc_command_encode_reply_payload_va which is same as
2095 normal command_encode_payload_va except command status type
2096 is provided as extra argument.
2098 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2100 * Added ~./silc directory handling. The directory includes the
2101 public and private keys for the client.
2103 Added silc_client_check_silc_dir, silc_client_create_identifier
2104 and silc_client_load_keys.
2106 * Implemented SILC protocol compliant public key. Added public
2107 and private key saving to and loading from files.
2109 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2110 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2111 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2112 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2113 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2115 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2116 silc_pkcs_load_[public/private]_key.
2118 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2120 * Added silc_server_get_route (route.[ch]) to get connection
2121 data for the fastest route for given ID.
2123 * Implemented INVITE command on client and server. The command
2124 were re-defined in the SILC Protocol Specification and the
2125 implementation now complies with the specification.
2127 * Implemented PING command on client and server.
2129 * Implemented NAMES command on client and server. The server side
2130 supports currently only normal server not router server yet.
2131 Some changes to NAMES definition in SILC protocol specification.
2133 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Implemented LEAVE command on client and server.
2137 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2138 again. This change was made to the protocol as well. Server
2139 should not violate the protocol specification anymore.
2141 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2143 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2144 was tested. SOCKS4 was not but should work anyway.
