1 Tue Mar 13 13:26:18 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added support to the server to enforce that commands are not
4 executed more than once in 2 seconds. If server receives
5 commands from client more frequently, timeout is registered
6 to process the commands. Affected file silcd/command.c.
7 Added new function silc_server_command_process_timeout.
9 * Changed NICK_NOTIFY handling in client library to check that
10 if the client's nickname was changed, so there is no need to
11 resolve anything from the server.
13 * Removed error printing from the WHOIS and IDENTIFY commands.
14 If error occurs then it is ignored silently in the client library.
15 The application, however, may map the received error to
16 human readable error string. The application currently maps
17 the NO_SUCH_NICKNAME error to string.
19 * Made the command status message public to the application. Moved
20 them from lib/silcclient/command_reply.c to
21 lib/silcclient/command_reply.h. The application can map the
22 received command status to the string with the
23 silc_client_command_status_message function.
25 * Added check to the server to check that client's ID is same
26 as the Source ID in the packet the client sent. They must
29 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
31 * Added dist-bzip hook to the Makefile.am to make bzip2
32 compressed distributions.
34 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
36 * Server now enforces the maximum length for the nickname and
37 the channel as protocol specification dictates. 128 bytes for
38 nickname and 256 bytes for channel name.
40 * Moved the WHOIS printing to the application. The client libary
41 does not print out the WHOIS information anymore, the application
42 must do it. Renamed silc_client_command_reply_whois_print to
43 the silc_client_command_reply_whois_save.
45 The client's idle time is also sent to the application now, and
46 the idle is shown on screen.
48 * Added silc_client_command_reply_identify_save to save the
49 received IDENTIFY entries.
51 * Do not check for channel private keys in message sending and
52 reception if the channel does not have the PRIVKEY mode set.
53 Affected file lib/silclient/client_channel.c.
55 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
57 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
58 just surfaced after chaning the JOIN procedure.
60 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
62 * Added silc_client_get_clients_by_list to get client entries
63 from Client ID list, that is returned for example by JOIN
64 and USERS command replies. The application should use this
65 function for example when JOIN command reply is received to
66 resolve the clients already on the channel (library does not
67 do that anymore as USERS command reply is not used in the JOIN
68 procedure anymore). Affected files lib/silcclient/silcapi.h and
69 lib/silcclient/idlist.c.
71 * JOIN command reply and USERS command reply returns now SilcBuffer
72 pointers instead of unsigned char pointers when returning
73 the client list and mode list.
75 * Added <Client ID> argument to the JOIN command reply, mainly
76 for the server to identify for which client the command was
77 originally sent. Updated protocol specs accordingly.
79 * Added SilcDlist private_key pointer to the SilcChannelEntry
80 in the client to support the channel private keys. Affected
81 file is lib/silcclient/idlist.h.
83 * Added SilcChannelPrivateKey argument to the function
84 silc_client_send_channel_message so that application can choose
85 to use specific private ke if it wants to. If it is not provided,
86 the normal channel key is used, unless private keys are set.
87 In this case the first (key that was added first) is used
88 as the encryption key.
90 * Implemented the support for channel private key handling.
91 Implemented the following functions:
93 silc_client_add_channel_private_key,
94 silc_client_del_channel_private_keys,
95 silc_client_del_channel_private_key,
96 silc_client_list_channel_private_keys and
97 silc_client_free_channel_private_keys
99 Affected file lib/silcclient/client_channel.c.
101 * Added the support for the private keys in the channel message
102 sending and encryption and in the message reception and
103 decryption. Affected funtions are
104 silc_client_send_channel_message and silc_client_channel_message.
106 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
108 * Added SKE's key verify callback to the client library's
109 KE protocol context. Affected files lib/silcclient/protocol.[ch].
111 * Removed the statement that server (or router) must send USERS
112 command reply when joining to the channel so that the client
113 knows who are on the channel. Instead, the client list and
114 client's mode list is now sent in the JOIN command reply to the
115 client who joined channel. This is better solution.
117 * Added function silc_server_get_users_on_channel and function
118 silc_server_save_users_on_channel to the silcd/server.[ch].
120 * Removed function silc_server_command_send_users from the
123 * Do not show topic on the client library anymore. The topic is
124 sent in the command reply notify to the application and the
125 application must show the topic now.
127 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
129 * Added client searching by nickname hash into the IDENTIFY and
130 WHOIS commands in the server as they were clearly missing from
131 them. Affected file is silcd/command.c.
133 * Fixed a bug in private message receiving in the client library.
134 The remote ID was freed and it wasn't supposed, now it is
137 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
139 * Minor fix to the channel payload; allocate the data area, as it
140 needs to be of specific length.
142 * If the key agreement port is zero then the operating
143 system will define the bound port. Affected files are
144 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
146 * Added new function silc_channel_payload_decrypt into the file
147 lib/silccore/silcchannel.[ch].
149 * Moved the channel message etc, check from silc_packet_decrypt
150 to applications. The library calls now a generic
151 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
152 when the packet is either normal or special. This was done to
153 allow more wide range of checking that was not allowed when
154 the code was in library. Now applications can do virtually any
155 checks to the packet and return to the library the decision how
156 the packet should be processed. Affected files are
157 lib/silccore/silcpacket.[ch].
159 Added silc_server_packet_decrypt_check to the server and
160 silc_client_packet_decrypt_check to the client library.
162 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
163 to send with specified source and destination information.
165 * Channel message delivery between routers was broken after the
166 channel key distribution was fixed earlier. The channel key
167 was used be to distributed to other routers as well which is not
168 allowed by the protocol. Now this is fixed and channel keys
169 really are cell specific and the channel message delivery between
170 routers comply with the protocol specification.
172 * Fixed various commands in server to check also the global list
173 for the channel entry and not just the local list. The affected
174 file silcd/command.c.
176 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
178 * Added assert()s to buffer formatting and unformatting routines
179 to assert (if --enable-debug) when error occurs. Affected
180 file: lib/silcutil/silcbuffmt.c.
182 * Changed to auto-reconnect to check whether the remote host is
183 router and register the re-connect timeout if it is. It used
184 to check that whether we are normal server, but router must do
185 auto-reconnect with another router as well. Affected file
188 * Removed the [<key len>] option from CMODE command as the cipher
189 name decides the key length, nowadays. See the defined ciphers
190 from the protocol specification.
192 * Added [<hmac>] option to the CMODE command to define the HMAC
193 for the channel. Added SILC_CMODE_HMAC channel mode.
195 * Added [<hmac>] option for the JOIN command so that user can
196 select which HMAC is used to compute the MACs of the channel
199 * Added Hmac field to the Channel Message Payload. The integrity
200 of plaintext channel messages are now protected by computing
201 MAC of the message and attaching the MAC to the payload. The
202 MAC is encrypted. Now, it is clear that this causes some
203 overhead to the size of the packet but rationale for this is that
204 now the receiver can verify whether the channel message decrypted
205 correctly and also when private keys are set for the channel the
206 receiver can decrypt the packet with several keys and check from
207 the MAC which key decrypted the message correctly.
209 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
210 lib/silccrypt/silccipher.[ch].
212 * Added silc_hash_len to return the digest length into the
213 lib/silcrypt/silchash.[ch].
215 * Rewrote parts of Silc Channel Payload interface in the
216 lib/silccore/silcchannel.[ch]. The encode function now also
217 encrypts the packet and parse function decrypts it.
219 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
221 * Fixed a minor formatting bug in the SKE's key material processing.
222 It actually might have processed the keys wrong way resulting
225 * Redefined the mandatory HMAC algorithms and added new algorithms.
226 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
227 and hmac-md5 truncated to 96 bits. The mandatory is now
228 hmac-sha1-96. Rest are optional (including the one that used
229 to be mandatory). Rationale for this is that the truncated HMAC
230 length is sufficient from security point of view and can actually
231 make the attack against the HMAC harder. Also, the truncated
232 HMAC causes less overhead to the packets. See the RFC2104 for
235 * Added new [hmac] configuration section. The SKE used to use
236 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
237 is of course wrong. The official names that must be proposed in
238 the SKE are the ones defined in the protocol specification
239 (hmac-sha1-96 for example). The user can configure any hmac
240 using any hash function configured in the [hash] section. At
241 least, the mandatory must be configured.
243 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
245 * Added HMAC list to the SKE proposal list. It has now both
246 hash algorithm list and HMAC list. This makes the protocol
247 incompatible with previous versions. The SKE now seems to work
248 the way it is supposed to work, for the first time actually.
250 * Defined plain Hash algorithms to the protocol specification.
253 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
255 * Implemented support for key agreement packets into the server.
256 Added functions silc_server_key_agreement and
257 silc_server_send_key_agreement. Other than these functions,
258 server has nothing to do with this packet.
260 * Added support for private message key packets into the server.
261 Added functions silc_server_private_message_key and
262 silc_server_send_private_message_key.
266 * Changed the silc_[client|server]_protocol_ke_set_keys to be
267 called in the protocol's final callback instead in the END
268 protocol state. This makes a little more sense and in the same
269 time in client we can use the same protocol routines for normal
270 key exchange and to key agreement packet handling as well.
272 * Added to both client's and server's KE protocol context the
273 SilcSKEKeyMaterial pointer to save the key material. We will
274 bring the key material to the protocol's final callback by doing
275 this. The final callback must free the key material.
277 * Added SKE's packet_send callback into client's KE protocol
278 context so that the caller can choose what packet sending function
279 is used. This way we can use different packet sending when
280 doing normal SKE when doing key agreement packet handling (in
281 the key agreement packet handling we do not want to encrypt
284 * Implemented the responder side of the key agreement routines
285 in the client. The client can now bind to specified port and
286 accept incoming key negotiation. The key material is passed
287 to the application after the protocol is over.
289 * Implemented the processing of incoming Key Agreement packet
290 in the client. Added function silc_client_key_agreement to
293 * Implemented the intiator side of the key agreement routines
294 in the client. The client can now initiate key agreement with
295 another remote client. The key material is passed to the
296 application after the protocol is over.
298 * Created client_keyagr.c to include all the key agreement
301 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
302 SILC_TASK_CALLBACK except that it is not static.
304 * Created client_notify.c and moved the Notify packet handling
305 from the client.[ch] into that file.
307 * Created client_prvmsg.c and moved all private message and
308 private message key routines from the client.[ch] into that file.
310 * Create client_channel.c and moved all channel message and
311 channel private key routines from the client.[ch] into that file.
313 * Changed silc_client_get_client_by_id_resolve to resolve with
314 WHOIS command instead of IDENTIFY command, in the file
315 lib/silclient/idlist.c.
317 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
319 * Implemented the SKE's responder side to the Client library.
321 * When FAILURE is received to the protocol do not trust it
322 blindly. Register a timeout to wait whether the remote closes
323 the connection as it should do it, only after that process the
324 actual failure. This was changed to both client and server.
326 * Added client_internal.h to include some of the structures
327 there instead of client.h in lib/silcclient/.
329 * Added function silc_task_unregister_by_callback to unregister
330 timeouts by the callback function.
332 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
334 * Some "Incomplete WHOIS info" errors has been appearing on the
335 log files. Took away the entry->userinfo check from WHOIS
336 reply sending. The entry->userinfo is now " " if client did not
337 provide one. I thought this was fixed earlier but something
338 is wrong still. Let's see if the error still appears.
340 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
342 * Fixed a minor bug in the login when the channel key is
343 re-generated in the server. It used to generate the key in
344 wrong order and thus caused problems in the channel traffic.
346 * Fixed a minor bug in channel key distsribution after
347 KICK command. The key was not sent to the router even though
350 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
352 * Added silc_ske_process_key_material_data as generic routine
353 to process any key material as the SILC protocol dictates. The
354 function is used by the actual SKE library but can be used by
355 applications as well. This relates to the private message keys
356 and the channel private keys since they must be processed the
357 same way the normal SILC session keys. The protocol dictates
358 this. Affected files: lib/silcske/silcske.[ch].
360 Added also silc_ske_free_key_material to free the
361 SilcSKEKeyMaterial structure.
363 * Defined silc_cipher_set_key function to set the key for
364 cipher without using the object's method function. The affected
365 files: lib/silccrypt/silccipher.[ch].
367 * Implemented silc silc_client_add_private_message_key,
368 silc_client_add_private_message_key_ske,
369 silc_client_del_private_message_key,
370 silc_client_list_private_message_keys and
371 silc_client_free_private_message_keys functions in the
374 Added functions silc_client_send_private_message_key to send
375 the Private Message Key payload and silc_client_private_message_key
376 to handle incoming Private Message Key payload.
378 * Added Cipher field to the Private Message Key payload to set
379 the cipher to be used. If ignored, the default cipher defined
380 in the SILC protocol (aes-256-cbc) is used.
382 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
384 * Removed lib/silcclient/ops.h file.
386 Redefined parts of the SILC Client Library API. Created new
387 file silcapi.h that deprecates the ops.h file and defines the
388 published Client Library API. Defined also private message key
389 API and channel private key API into the file.
391 This is the file that the application must include from the
392 SILC Client Library. Other files need not be included by
393 the application anymore.
395 * Added new key_agreement client operation callback and also
396 defined the Key Agreement library API for the application.
398 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
400 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
401 is used by clients to request key negotiation between another
402 client in the SILC network. If the negotiation is started it
403 is performed using the SKE protocol. The result of the
404 negotiation, the secret key material, can be used for example
405 as private message key.
407 Implemented the Key Agreement payload into the files
408 lib/silccore/silauth.[ch].
410 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
412 * Redefined ciphers for the SILC protocol. Added some new ciphers
413 and defined the key lengths for the algorithms. Changed the
414 code accordingly. The default key length is now 256 bits.
416 * Fixed SKE key distribution function silc_ske_process_key_material
417 when the key length is more than 128 bits. The default key
418 length in SILC is now 256 bits.
420 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
421 to indicate unsupported algorithm.
423 * Renamed rijndael.c to aes.c and all functions as well.
425 * Fixed a long standing channel key setting bug in client library.
426 Weird that it has never surfaced before.
428 * Fixed bug in channel deletion. If the entire channel is removed
429 then it must also delete the references of the channel entry
430 from the client's channel list as the client's channel entry and
431 the channel's client entry share same memory.
433 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
435 * Implemented CONNECT and SHUTDOWN commands in the client.
437 * Implemented CLOSE command to the client.
439 * Added the function silc_idlist_find_server_by_name into the
440 files silcd/idlist.[ch].
442 Added the function silc_idlist_find_server_by_conn into the
443 files silcd/idlist.[ch].
445 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
447 * DIE command was renamed to SHUTDOWN. Updated the both code
450 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
451 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
453 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
456 * Added function silc_server_create_connection function to create
457 connection to remote router. My server implementation actually
458 does not allow router to connect to normal server (it expects
459 that normal server always initiates the connection to the router)
460 so the CONNECT command is only good for connecting to another
463 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
465 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
466 or some other client was kicked from the channel.
468 Implemented the handling of the notify type to both client
471 Implemented silc_server_send_notify_kicked to send the KICKED
472 notify. It is used to send it to the server's primary router.
474 * Implemented the KICK command into server and client.
476 * Added `query' argument to the silc_idlist_get_client function
477 to indicate whether to query the client from server or not if
480 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
481 to indicate that the client is not channel founder.
485 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
487 * Removed the rng context from SilcPacketContext structure and
488 changed that the packet routine uses the Global RNG API.
490 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
492 * Added support for quit message that client can "leave" on the
493 channel when it quits the SILC. It is ditributed inside the
494 SILC_NOTIFY_TYPE_SIGNOFF notify type.
496 Added silc_server_free_client_data that will take the
497 signoff message as argument.
499 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
501 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
503 * Updated parts of the protocol specification to keep it up
506 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
508 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
509 payloads in one packet.
511 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
512 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
513 use now the new List flag.
515 * Also deprecated the following packet types: REPLACE_ID,
516 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
518 * Added list support for Notify packet in server.
520 * Added silc_server_send_notify_channel_change to send the
521 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
522 the silc_server_send_replace_id.
524 * Added silc_server_send_notify_nick_change to send the
525 NICK_CHANGE notify type. Deprecates the function
526 silc_server_send_replace_id.
528 * Added silc_server_send_notify_join to send the JOIN notify type.
529 Deprecates the function silc_server_send_new_channel_user.
531 * Added silc_server_send_notify_leave to send LEAVE notify type.
532 Deprecates the function silc_server_send_remove_channel_user.
534 * Added silc_server_send_notify_cmode and
535 silc_server_send_notify_cumode to send CMODE and CUMODE notify
536 types. Deprecates the silc_server_send_set_mode function.
538 * Added SERVER_SIGNOFF notify type to indicate that server has
539 quit. This means that all clients on the channel from that
540 server will drop. This can be also used when netsplit happens.
542 Deprecated REMOVE_ID packet type since it is not needed anymore
545 Added silc_server_send_notify_server_signoff to send the
546 SERVER_SIGNOFF notify type. Deprecates the function
547 silc_server_send_remove_id.
549 Added also silc_server_send_notify_signoff to send the
552 * Employed the PKCS #1. It is the mandatory way to do RSA in the
553 SILC protocol from this day on. Changed the protocol
554 specification as well.
556 * Added silc_server_send_notify_topic_set to send TOPIC_SET
557 notify type. It is used between routers to notify about
558 topic changes on a channel.
560 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
563 * Partly updated the protocol specification to comply with the
564 changes now made. It is still though a bit outdated.
566 * The JOIN notify type now takes one extra argument <Channel ID>.
567 The packet used to be destined to the channel but now the
568 JOIN type may be sent as list thus it is impossible to
569 destine it to any specific channel. By adding this argument
570 it is again possible.
572 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
574 * Added CREDITS file. The CHANGES and CREDITS file will appear
575 in the distribution as well.
577 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
579 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
580 types in the server's silcd/packet_receive.c.
582 * Implemented CMODE and CUMODE to work in router environment.
584 * Fixed minor encoding and decoding buglet from the
585 lib/silccore/silcmode.c.
587 * Fixed buffer overflow from lib/silcclient/command.c in USERS
590 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
592 * Changed all SilcConfigServer* and silc_config_server* to
593 SilcServerConfig* and silc_server_config*, respectively.
596 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
598 * Associated the ID (client or server ID) to the Authentication
599 Payload to avoid any possibility of forging. Updated the
600 protocol specification and the code accordingly.
602 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
604 * The RSA key length is now save to the RsaKey context in the
605 key generation process in lib/silccrypt/rsa.c. The key length
606 is now used to figure out the maximum size of the block allowed
607 to be encrypted/signed.
609 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
610 is equivalent to the silc_mp_mp2bin but does not allocate any
613 * Changed silc_mp_mp2bin API to take length argument. If it is
614 non-zero then the buffer is allocated that large. If zero, then
615 the size is approximated using silc_mp_sizeinbase, which however
618 * Created Global RNG API which is global RNG that application can
619 initialize. After initializing, any routine anywhere in the
620 code (including library) can use RNG without allocating a new
621 RNG object. This was done to allow this sort of use of the
622 RNG in code that has no chance to allocate RNG object. All
623 applications currently allocate this and many routines in the
624 library use this. Affected file lib/silccrypt/silcrng.[ch].
626 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
627 it to use the Global RNG API.
629 * Defined Authentication Payload into protocol specification that
630 is used during SILC session to authenticate entities. It is
631 used for example by client to authenticate itself to the server
632 to obtain server operator privileges.
634 Implemented this payload into the lib/silccore/silcauth.[ch].
635 Implemented also routines for public key based authentication
636 as the new protocol specification dictates.
638 Moved definitions of different authentication methods from
639 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
641 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
642 silc_pkcs_verify and silc_pkcs_sign_with_hash and
643 silc_pkcs_verify_with_hash functions into the file
644 lib/silccrypt/silcpkcs.[ch].
646 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
648 * The client entry's userinfo pointer must be always valid.
649 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
650 will fail since it requires the userinfo. Now, the userinfo
651 is allocated as "" if actual userinfo does not exist. Actually,
652 it must exist and it is totally Ok to drop client connections
653 that does not announce the userinfo. However, we will make
654 this workaround for now.
656 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
657 to return the remote port by socket.
659 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
661 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
662 SILC_SERVER_PENDING_EXEC and added an new macro
663 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
664 data or when error occurs while processing the pending command.
666 Added new argument `destructor' into silc_server_command_pending
667 and to the SilcServerCommandPending object. This destructor is
668 now called after calling the pending callback or if error occurs
669 immediately. If error occurs the actual pending callback won't
670 be called at all - only the destructor. The destructor may be
671 NULL if destructor is not needed.
673 All this applies for client library code as well. Similar
674 changes were made there as well for the pending commands.
676 In the client, the application must now allocate the
677 SilcClientCommandContext with the silc_client_command_alloc
680 * Added reference counter to the SilcServerCommandContext. Added
681 function silc_server_command_alloc and silc_server_command_dup
684 Same type of functions added to the client library for the same
687 * Removed the cmd_ident from IDListData away since it is now
688 global for all connections. It is the command identifier used
689 in command sending and with pending commands. The affected file
692 * Added reference counter to the SilcSocketConnection objecet to
693 indicate the usage count of the object. The object won't be
694 freed untill the reference counter hits zero. Currently only
695 server uses this, and client ignores it. The client must be
696 set to use this too later. The affected files are
697 lib/silccore/silcsockconn.[ch]. Added also the function
698 silc_socket_dup to increase the reference counter.
700 This was mainly added because it is possible that the socket
701 is removed underneath of pending command or other async
702 operation. Now it won't be free'd and proper DISCONNECTING
703 flags, etc. can be set to avoid sending data to connection that
704 is not valid anymore.
706 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
707 the connection. After that it sets SILC_SET_DISCONNECTED.
708 It is, however, possible that the socket data is not still freed.
709 The silc_server_packet_process now checks that data is not
710 read or written to connection that is DISCONNECTED. The socket
711 get's freed when the reference counter hits zero.
713 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
715 * Changed the client operation API: channel_message operation's
716 `sender' is now the client entry of the sender, not the nickname
717 and the `channel' is the channel entry, not the channel name.
719 In the private_message operation the `sender' is now also the
720 client entry of the sender not the nickname.
722 Affected file is lib/silcclient/ops.h and all applications
723 using the client operations.
725 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
727 * Moved the calling of ops->connect() from connect_to_server_final
728 into receive_new_id functin since that is the point when the
729 client is actually allowed to send traffic to network. The
730 affected file is lib/silcclient/client.c.
732 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
734 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
735 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
736 (if needs broadcasting) instead of broadcasting the packets one
737 by one which would make a burst in the network traffic.
739 * Added `broadcast' argument to the functions in silcd/server.[ch]
740 silc_server_create_new_channel[_with_id] to indicate whether
741 to send New Channel packet to primary router.
743 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
745 * Added new function into the silcd/server.[ch] files:
746 silc_server_create_new_channel_with_id to create new channel with
747 already existing Channel ID.
749 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
750 lib/silccore/silcpacket.h. This packet is used t send list of
751 Set Mode payloads inside one packet. Server uses this to set
752 the modes for the channels and clients on those channels, that it
753 announced to the router when it connected to it. The protocol
754 specification has been updated accordingly.
756 * The silc_server_new_channel did not handle the packet coming
757 from normal server as it normally does not send that. However,
758 when it announces its channels it does send it. Implemented
759 the support for that.
761 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
762 into the file lib/silccore/id.h.
764 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
766 * Fixed memory leaks in the functions silc_idlist_del_client,
767 silc_idlist_del_channel and silc_idlist_del_server in the file
768 silcd/idlist.c. All of those leaked like a sieve.
770 * Fixed some small memory leaks in the client's function
771 silc_client_notify_by_server.
773 * Added functions into silcd/server.c: silc_server_announce_clients,
774 silc_server_announce_channels and silc_server_announce_server.
775 These functions are used by normal and router server to announce
776 to its primary router about clients, channels and servers (when
777 router) that we own. This is done after we've connected to the
780 These functions effectively implements the following packet types:
781 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
782 and SILC_PACKET_NEW_ID_LIST.
784 * Added new functions into the silcd/packet_receive.[ch]:
785 silc_server_new_id_list, silc_server_new_channel_list and
786 silc_server_new_channel_user_list to handle the incoming
787 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
789 * Added support of changing Channel ID in the function
790 silc_server_replace_id. If the server that announces a channel
791 to the router already exists in the router (with same name but
792 with different Channel ID), router is responsible to send
793 Replace ID packet to the server and force the server to change
794 the Channel ID to the one router has.
796 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
797 client that the Channel ID has been changed by the router. The
798 normal server sends this to the client. Client must start using
799 the new Channel ID as the channel's ID.
801 Implemented handling of this new type into lib/silcclient/client.c
802 into the function silc_client_notify_by_server.
804 * Added new function silc_idlist_replace_channel_id into the files
805 silcd/idlist.[ch] to replace the Channel ID.
807 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * Call silc_server_command_identify_check always when processing
810 the IDENTIFY command in silcd/command.c
812 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
814 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
815 send keepalive packets. The packet can be sent by clients,
818 Added function silc_socket_set_heartbeat into the file
819 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
820 If not set, the heartbeat is not performed. The actual
821 heartbeat is implemented in the low level socket connection
822 library. However, application is responsible of actually
825 Added silc_server_send_heartbeat to send the actual heartbeat
826 packet into silcd/packet_send.[ch]. Server now performs
827 keepalive with all connections.
829 * Added silc_task_get_first function into lib/silcutil/silctask.c
830 to return the timeout task with shortest timeout. There was a bug
831 in task unregistration that caused problems. TODO has been
832 updated to include that task system must be rewritten.
834 * The client library will now resolve the client information when
835 receiving JOIN notify from server for client that we know but
836 have incomplete information.
838 * Rewrote parts of silc_server_remove_from_channels and
839 silc_server_remove_from_one_channel as they did not remove the
840 channel in some circumstances even though they should've.
842 * Encryption problem encountered in server:
844 The LEAVE command used to send the Channel Key packet to the
845 router immediately after generating it. However, the code
846 had earlier sent Remove Channel user packet but not immediately,
847 ie. it was put to queue. The order of packets in the router
848 was that Channel Key packet was first and Remove Channel User
849 packet was second, even though they were encrypted in the
850 reverse order. For this reason, MAC check failed. Now, this
851 is fixed by not sending the Channel Key packet immediately but
852 putting it to queue. However, this is more fundamental problem:
853 packets that are in queue should actually not be encrypted
854 because packets that are sent immediately gets encrypted
855 actually with wrong IV (and thus MAC check fails). So, packets
856 that are in queue should be encrypted when they are sent to
857 the wire and not when they put to the queue.
859 However, the problem is that the current system has not been
860 designed to work that way. Instead, the packet is encrypted
861 as soon as possible and left to the queue. The queue is then
862 just purged into wire. There won't be any fixes for this
863 any time soon. So, the current semantic for packet sending
866 o If you send packet to remote host and do not force the send
867 (the packet will be in queue) then all subsequent packets to the
868 same remote host must also be put to the queue. Only after the
869 queue has been purged is it safe again to force the packet
872 o If you send all packets immediately then it safe to send
873 any of subsequent packets through the queue, however, after
874 the first packet is put to queue then any subsequent packets
875 must also be put to the queue.
877 Follow these rules and everything works fine.
879 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
881 * Added new function silc_server_remove_clients_by_server to
882 remove all client entries from ID list when the server connection
883 is lost. In this case it is also important to invalidate all
884 client entires as they hold the invalid server entry. This
885 fixes fatal bug when server has lost connection and will reconnect
888 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
890 * Made some sanity checks to silc_server_daemonise like to check
891 whether the requested user and group actually exists.
893 * Added sanity check to SKE's silc_ske_responder_finish to check
894 that the public and private key actually is valid.
896 * Invalidate the client's nickname when receiving Replace ID
897 packet and the Client ID is being replaced. This means that the
898 server will query the nickname if someone needs it (client)
901 * Sort the ID Cache in client library when the ID Cache data
902 has changed (needs sorting).
904 * Do not allow for SILC client to create several connections to
905 several servers. The client does not support windows right now
906 and generating multiple connections causes weird behaviour.
908 Irssi-silc client does support windows and can handle several
909 connections without problems, see: www.irssi.org and SILC plugin.
911 * Fixed some places where client was added to the IDList. The
912 rule of thumb is following (in order to get everything right):
913 If the client is directly connected local client then the
914 `connection' argument must be set and `router' argument must be
915 NULL to silc_idlist_add_client function. If the client is not
916 directly connected client then the `router' argument must
917 bet set and the `connection' argument must be NULL to the
918 silc_idlist_add_client function.
920 * The funtion silc_server_packet_send_local_channel actually did
921 not check whether the client was locally connected or not. It
922 does that now. Fixed a bug related to LEAVE command.
924 * Fixed Remove Channel User payload parsing bug in server's
925 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
927 * The server's silc_server_save_channel_key now checks also the
928 global ID list for the channel as it might not be in the local
929 list. Fixed a bug related to LEAVE command.
931 * Is this the end of the [<unknown>] buglet that has been lurking
932 around for a long time? A little for loop fix in server's
933 silc_server_command_whois_parse that is used by both IDENTIFY
934 and WHOIS command. At least, this was a clear bug and a cause
935 of one type of [<unknown>] buglet.
937 * WHOIS and IDENTIFY commands call the function
938 silc_server_command_[whois/identify]_check function even if
939 we are not router server.
941 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
943 * Added --with-gmp configuration option. If set the GMP
944 is always compiled in the SILC source tree. If not set then
945 it is checked whether the system has the GMP3 installed. If
946 it has then the GMP won't be compiled (the system's headers
947 and library is used), if it doesn't have it then the GMP is
948 compiled in the SILC source tree.
950 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
952 * Changed RSA private exponent generation to what PKCS #1
953 suggests. We try to find the smallest possible d by doing
954 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
955 not security fix but optimization.
957 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
959 * Added new config entry [Identity] to fork the server and run
960 it as specific user and group. A patch from Bostik.
962 * Imported Dotconf configuration library into lib/dotconf.
963 This will be used to create the SILC configuration files later.
964 It will appear in the distsribution after this commit.
966 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
968 * A big code auditing weekend happening. Auditing code for
969 obvious mistakes, bugs and errors. Also, removing any code
972 Removed files for being obsolete:
974 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
975 inline in the file lib/silcutil/silcbuffer.h)
977 o lib/silcutil/silcbufutil.c (the header has inline versions)
979 Changed code to fix possible error conditions:
981 o The buffer formatting routines now check that the destination
982 buffer really has enough space to add the data. This applies for
983 both buffer formatting and unformatting
984 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
985 unformatting was changed to accomodate following rules:
986 XXX_*STRING_ALLOC will allocate space for the data into the pointer
987 sent to the function while XXX_*STRING will not allocate or copy
988 the data into the buffer. Instead it sets the pointer from the
989 buffer into the pointer sent as argument (XXX_*STRING used to
990 require that the pointer must be allocated already). This change
991 makes this whole thing a bit more consistent and more optimized
992 (note that the data returned in the unformatting with XXX_*STRING
993 must not be freed now). The routines return now -1 on error.
995 o Tried to find all code that use buffer_format and buffer_unformat
996 and added return value checking to prevent formatting and
997 especially unformatting errors and possible subsequent fatal
1000 o Changed ske->x and ske->KEY to mallocated pointers in
1001 lib/silcske/silcske.h. Fixed possible data and memory leak.
1003 o Added return value checking to all *_parse* functions. Fixed
1004 many memory leaks as well.
1006 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
1007 so that buffer overflows would not happen. All code now also
1008 checks the return value as it can fail.
1010 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1012 * Added reconnection support to server if the normal server looses
1013 its connection to the router (for example if router is rebooted).
1014 The server performs normal reconnection strategy implemented
1015 to the server. Affected file silcd/server.c.
1017 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1019 * Added new packet type SILC_PACKET_SET_MODE that is used to
1020 distribute the information about changed modes (for clients,
1021 channels and clients channel modes) to all routers in the
1022 network. Updated the protocol specification accordingly.
1024 Added functions into silcd/packet_send.c and
1025 silcd/packet_receive.c: silc_server_send_set_mode,
1026 silc_server_set_mode.
1028 Added new files silcmode.[ch] into lib/silccore that implements
1029 the encoding and decoding of Set Mode Payload. Added new type
1030 SilcSetModePayload. Moved the definitions of different modes
1031 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1033 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1035 * Oops, a little mistake in server's connection authentication
1036 protocol. The protocol is not ended with FAILURE but with
1037 SUCCESS if the authentication is Ok. :) Affected file is
1040 * Implemented NICK_CHANGE notify handling in server in the file
1041 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1042 the local clients on the channel. After the changing nickname
1043 in router environment snhould work and the [<unknown>] nickname
1044 should appear no more.
1046 The silc_server_replace_id function that receives the Replace ID
1047 payload now sends the NICK_CHANGE notify type also in the file
1048 silcd/packet_receive.c
1050 * Changed WHOIS and IDENTIFY command to support the maximum amount
1051 of arguments defined in protocol specs (3328 arguments). This
1052 fixed a bug that caused problems when there were more than three
1055 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1057 * Added extra parameter, command identifier, to the
1058 silc_client_send_command so that explicit command identifier
1061 Changed that ID list routines uses specific command identifier
1062 when sending WHOIS/IDENTIFY requests to the server so that they
1063 can be identified when the reply comes back.
1065 Affected files lib/silcclient/command.[ch],
1066 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1068 * Added `sender' argument to silc_server_packet_send_to_channel
1069 to indicaet the sender who originally sent the packet to us
1070 that we are now re-sending. Ignored if NULL. Affected file
1071 silcd/packet_send.[ch].
1073 * Added some server statistics support in silcd/server_internal.h
1074 SilcServerStatistics structure and around the server code. Also
1075 send some nice statistics information when client is connecting
1078 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1080 * Fixed channel ID decoding in server's JOIN command reply in
1081 silcd/command_reply.c
1083 * Fixed braodcasting of replace ID payload to not to send it if
1084 we are standalone server in silcd/packet_receive.c.
1086 * Fixed all channel message sending routines to not to send
1087 packets to clients that has router set, since they are routed
1088 separately in the same function earlier. Affects file
1089 silcd/packet_send.c and all channel packet sending functions.
1091 * In USERS reply, res_argv[i] are not allocated, the table
1092 is allocated. Thus changed that free the table, not its
1095 * In server's whois_check and identify_check if the client is
1096 locally connected do not send any WHOIS commands - they are not
1099 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1101 * Fixed some minor bugs in client when sending WHOIS command. The
1102 arguments was in wrong order.
1104 * Removed statis function add_to_channel from server in
1105 silcd/command.c that was previously used with the joining but
1108 * Tested USERS command in router environment successfully with two
1109 routers, two servers and two clients.
1111 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1113 * Reorganized the USERS command and command reply in client library
1114 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1115 When the command is given by user we register a pending command
1116 callback that will reprocess the command after the reply has been
1117 received from the server. When reprocessing the packet we then
1118 display the information. Thus, the USERS information is displayed
1119 now in the command callback instead of in the command reply
1120 callback. The processing of the command is same as previously
1121 when server has sent the command reply in the JOINing process.
1123 * Added to USERS command in silcd/command_reply.c to join the client,
1124 we didn't use to know about, to the channel after we've created
1125 a client entry for it. Also, for clienet we did know already still
1126 check whether it is on the channel or not and add it if not.
1128 * Removed silc_server_command_join_notify as the function and its
1131 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1133 * Changed the client's pending command handling to the same as the
1134 server's pending command handling. It is also now possible to
1135 execute command reply functions from other command reply
1136 function as the function callbacks for commands and command
1137 replies are one and same. The pending commands are not static
1138 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1139 in client connection context. Thus, pending commands are server
1140 connection specific as it is convenient.
1142 Changed the function silc_client_command_pending and
1143 silc_client_command_pending_del and added new function
1144 silc_client_command_pending_check. Removed the
1145 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1148 * Added cmd_ident, current command identifier, to the client
1149 connection context in lib/silcclient/client.h to keep track on
1150 command identifiers used in command sending. Client's command reply
1151 function handling now supports the mandatory command identifiers.
1153 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1154 funtions in client to fully support pending command callbacks.
1156 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1157 as one of the arguments to the application in the command reply
1160 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1161 before first releasing SILC but came back. Now it is removed again
1162 and should come back nomore. The FORWARDED flag was used only
1163 by the JOINing procedure by forwarding the command packet to router.
1164 Now, the JOINing procedure has been changed to more generic (due
1165 to various router environment issues) and FORWARDED is not needed
1166 anymore for anything. The protocol specification is yet to be
1169 Now, removed silc_server_packet_forward from server and the flag
1170 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1172 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1174 * Renamed NAMES command to USERS command. The NAMES was named that
1175 due to historical reasons. Now it is renamed. Also, rewrote
1176 parts of the USERS command. The nickname list is not sent anymore
1177 by the server. Only Client ID and mode lists are sent in the USERS
1178 command. Changed this also to the protocol specification.
1180 The client now resolves the names and stuff after it receives
1181 the USERS list from the server when joining to the channel.
1183 * WHOIS and IDENTIFY commands has been changed to support multiple
1184 Client ID's per command. One can now search for multiple users
1185 in the network by sending only one WHOIS or IDENTIFY command.
1186 Changed the code and the protocol specifications.
1188 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1189 uses silc_server_command_whois_parse to parse the request. */
1191 * If normal server, do not parse the WHOIS and IDENTIFY requests
1192 before sending it to the router. Saves some time.
1194 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1196 * Fixed JOIN command on client library. Wrong number of arguments
1197 used to crash the client.
1199 * Added silc_server_channel_has_global function to check whether
1200 channel has global users or not.
1202 * Added silc_server_channel_has_local function to check whether channel
1203 has locally connected clients on the channel.
1205 * The silc_server_remove_from_one_channel now checks whether the
1206 channel has global users or not after given client was removed from
1207 the channel. It also checks whether the channel has local clients
1208 on the channel anymore. If it does not have then the channel entry
1209 is removed as it is not needed anymore.
1211 * The silc_server_notify now checks on JOIN notify whether the joining
1212 client is one of locally connected or global. If it is global then
1213 the channel has now global users on the channel and that is marked
1214 to the channel entry. Also, it now saves the global client to
1215 global list who is joining and JOINs it to the channel. This is
1216 for normal server, that is.
1218 Changed silc_server_send_notify_on_channel,
1219 silc_server_packet_relay_to_channel and
1220 silc_server_packet_send_to_channel check if we are normal server
1221 and client has router set (ie. global client) do not send the
1222 message to that client, as it is already routed to our router.
1224 * Implemented LEAVE notify type handling in silc_server_notify
1227 * Tested LEAVE command in router environment successfully. Tested
1228 with two routers, two servers and two clients.
1232 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1234 * Implemented SIGNOFF notify type handling in silc_server_notify
1237 * silc_server_remove_id now removes the client entry from all channels
1238 it has joined and thusly sends SIGNOFF notify type.
1240 * Rewrote the NAMES list generation in server by removing two excess
1241 loops. The lists are created now inside one loop.
1243 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1245 * silc_server_remove_channel_user checks now also global list
1246 for channel and client.
1248 * silc_server_new_channel_user checks now both local and global
1249 list for channel and client. Fixed a bug in client id decoding.
1250 Used to decode wrong buffer.
1252 * silc_server_channel_message checks now both local and global
1253 list for channel entry.
1255 * Tested channel joining (hence JOIN) in router environment
1256 successfully. Tested with two routers, two servers and two
1259 * Tested channel message sending in router environment successfully.
1261 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1263 * Added silc_server_save_channel_key into server.[ch] to save the
1264 received channel key in Channel Key payload processing. It is
1265 also used in JOIN command reply handling.
1267 Equivalent function silc_client_save_channel_key added into
1268 client.[ch] into client library.
1270 * Changed JOIN command reply to send information whether the channel
1271 was created or not (is existing already) and the channel key
1272 payload. Changed protocol specs accordingly.
1274 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1275 the request was sent by ID and not by nickname. Crashed on
1278 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1280 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1281 now correctly save the received data.
1283 * silc_server_free_sock_user_data now notifies routers in the
1284 network about entities leaving the network.
1286 At the same time implemented functions silc_server_remove_id
1287 and silc_server_send_remove_id to receive and send REMOVE_ID
1288 packets. The packet is used to notify routers in the network
1289 about leaving entities. The ID removed will become invalid in
1292 * Added function silc_idlist_del_server into server. Removes and
1293 free's server entry from ID list.
1295 * silc_server_private_message function now checks, if we are router,
1296 that the destination ID really is valid ID, naturally.
1298 * In router when NEW_ID packet is received (for new client) the
1299 hash of the Client ID is saved in the ID Cache but the
1300 client->nickname is set to NULL, instead of putting the hash
1303 IDENTIFY command now also checks that client->nickname must be
1304 valid. If it is not if will request the data from the server who
1305 owns the client. Added new function
1306 silc_server_command_identify_check.
1308 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1309 to set the command to already allocated Command Payload.
1311 * Tested private message sending in router environment with two
1312 routers, two servers and two clients. Fixed minor bugs and now
1315 * Fixed segfault from client's NAMES command. Used to crash if
1318 * Forwarded packets must not be routed even if it is not destined
1319 to the receiver. Changed server code comply with this.
1321 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1323 * Added `require_reverse_mapping' boolean value to ServerParams
1324 structure. If TRUE (not default) the server will require that
1325 the connecting host has fully qualified domain name.
1327 If the reverse mapping is not required and hostname could not be
1328 found the IP address is used as hostname.
1330 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1332 * Implemented version string checking to both client and server.
1333 The check is incomplete currently due to the abnormal version
1334 strings used in development version of SILC.
1336 * Changed all command functions in server to use the new
1339 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1341 * Changed char *data to unsigned char *data in ID Cache system to
1342 support binary data as ID Cache data. Changed code to support
1343 binary data in lib/silccore/idcache.c.
1345 * Renamed silc_server_packet_relay_command_reply to
1346 silc_server_command_reply as it is normal packet receiving
1347 function. Rewrote the function to accept command replys for
1348 servers and not only for clients.
1350 * Mark remote router always as registered server if we are connecting
1351 to it. Otherwise, commands sent by the router to us are ignored.
1353 * All ID List find routines now returns the ID Cache Entry pointer
1354 as well if requested.
1356 * WHOIS command works now in router environment, tested with two
1357 routers, two servers and two clients.
1359 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1360 in router environment (as it is almost equivalent to WHOIS) but
1361 hasn't been tested thoroughly. Added new functions:
1363 silc_server_command_identify_parse
1364 silc_server_command_identify_send_reply
1365 silc_server_command_identify_from_client
1366 silc_server_command_identify_from_server
1368 * Disabled route cache adding because adding two different ID's with
1369 same IP replaces the old cache entry thus giving wrong route.
1370 The entry->router->connection is always the fastest route anyway
1371 so route cache may not be needed. Of course, new routes maybe
1372 established after receiving the ID when the entry->router->connection
1373 might not be anymore the most optimal.
1375 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1377 * Add route cache for received ID for fast routing.
1379 * Added silc_server_packet_route to route received packet on router
1380 that is not destined to us.
1382 * Renamed silc_server_get_route to silc_server_route_get.
1384 * Added id_string and id_string_len fields into SilcServer to
1385 include encoded ServerID for fast comparing without excess
1386 encoding of the ID's.
1388 * Cleaned up WHOIS command on server side. Added following static
1391 silc_server_command_whois_parse
1392 silc_server_command_whois_check
1393 silc_server_command_whois_send_reply
1394 silc_server_command_whois_from_client
1395 silc_server_command_whois_from_server
1397 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1398 arguments in command replies. All command functions should be
1399 updated to use this macro.
1401 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1403 * Minor typo fixes on command reply handling on server.
1405 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1407 * Added silc_server_command_add_to_channel internal routine to add
1408 the client to the channel after router has created the channel and
1409 sent command reply to the server.
1411 * Added generic silc_server_send_command to send any command from
1414 * Use static buffer with ID rendering instead of duplicating data.
1416 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1418 * Fixed a channel user mode bug when joining to a channel server gave
1419 everybody channel founder rights, oops.
1421 * We mark ourselves as the router of the incoming server connection
1422 if we are router ourselves. This way we can check in some packet
1423 sending functions whether it is locally connected server. For
1424 incoming router connections we put NULL.
1426 * For router sending packets locally means now always sending the
1427 packet cell wide; to local clients and local servers. For normal
1428 server sending packet locally means sending it to only local
1431 * Fixed the JOIN command to really work in router environment. If the
1432 channel is created it is always created by the router. Router is
1433 also responsible of making the initial joining to the channel,
1434 sending JOIN notify to the sending server and distributing
1435 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1436 does not exist server doesn't do anything else but forward the
1437 command to the router which performs everything.
1439 * Added silc_server_send_channel_key function to send the Channel Key
1442 * Added silc_server_create_channel_key to create new channel key. The
1443 channel key is now re-generated everytime someone joins or leaves
1444 a channel, as protocol dictates. Note: channel->key_len is the
1447 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1449 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1450 packet_receive.[ch] to separate packet sending and receiving
1451 routines. The server.[ch] now includes everything else including
1452 actual packet processing (writing and reading data) and other
1455 Renamed silc_server_private_message_send_internal to
1456 silc_server_send_private_message. The routine is still though
1457 used only to relay private messages as server does not send
1458 private messages itself.
1460 Renamed silc_server_new_channel to silc_server_create_new_channel
1461 and added new function sicl_server_new_channel that handles the
1462 incoming New Channel packet. Added also new sending function
1463 silc_server_send_new_channel to send New Channel Payload.
1465 * Added new function silc_server_notify to process incoming notify
1466 packet to the server/router. Server may then relay the notify
1467 to clients if needed.
1469 * Added new function silc_server_new_channel_user to process incoming
1470 New Channel User packet. Router will redistribute the packet and
1471 send JOIN notify to its local clients and locally connected servers
1472 if needed. Normal server will send JOIN notify to its local client
1473 on same channel when received this packet. Added also corresponding
1474 sending function silc_server_send_new_channel_user to sent the
1477 * Added boolean route argument to send_notif_to_channel and
1478 packet_send_to_channel functions to attempt to route the packet
1479 if it is TRUE and send only locally if it is FALSE.
1481 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1483 * silc_server_replace_id now broadcasts the received replace ID
1484 packet if it is not broadcast packet already. The router must
1485 broadcast to inform other routers about changed ID.
1487 * Added backpointer to server's router into SilcServer context in
1488 silcd/server_internal.h.
1490 * Fixed silc_server_packet_broadcast to send correct broadcast
1493 * The channel key is now distributed to the local client as soon
1494 as it is received from the router (in router environment) so that
1495 no other packet may be sent for the channel until client has
1498 * silc_server_remove_channel_user now broadcasts the received
1499 Remove Channel User packet if it is not broadcast packet already.
1500 The router must broadcast to inform other routers about removed
1503 * Added users field into SilcPacketContext that is a reference count
1504 of the context. One can increase the reference count by calling
1505 silc_packet_context_dup which is now changed to just increase the
1506 reference count instead of duplicating the data. The reference
1507 count is decresed by calling silc_packet_context_free that will
1508 free the data after the reference count hits zero.
1510 For now on the packet context and everything allocated into it
1511 (including the raw packet from network) must be freed by calling
1512 the new silc_packet_context_free function. Added also new function
1513 silc_packet_context_alloc that must be used now to allocate the
1514 context. This also means that if a routine is asynchronous from
1515 silc_[client/server]_packet_parse_type the packet context must
1516 be duplicated by calling silc_packet_context_dup. Otherwise it
1517 gets free'd after silc_[client/server]_packet_parse_type returns.
1518 Also, one must remember that if packet is duplicated then its
1519 reference count must be decresed by calling the free function as
1520 many times as it was duplicated.
1522 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1523 from both client and server.
1525 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1527 * Made joining to a channel working in router environment.
1529 * Cleaned up JOIN command on server side and create function
1530 silc_server_command_join_channel internal routine to make the
1533 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1535 * Changed silc_command_pending list to SilcDList. Also, added
1536 `ident' field to SilcServerCommandPending structure to identify
1537 the reply and to call correct callback.
1539 Added silc_server_command_pending_check function to replace the
1540 corresnponding macro. The silc_command_pending list is not
1543 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1544 to set identifier to previously allocated Command Payload. It
1545 is used to set identifier for command when resending Command
1548 * Added silc_command_payload_encode_payload to encode Command
1549 Payload buffer from SilcCommandPayload structure.
1551 * Added silc_argument_payload_encode_payload to encode Argument
1552 payload buffer from SilcArgumentPayload structure.
1554 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1556 * Changed WHOIS command to support router connection on server side.
1557 The whois request is always sent to router unless the server is
1558 standalone server. After server has received the reply from the
1559 router will it send the reply to the client.
1561 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1562 broadcast received broadcast packet. The function is used only
1563 by router. The broadcast packet is always sent to the router's
1566 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1567 render given ID to printable string, for log files for example.
1569 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1571 * Made basic router to router connections working. At least they
1572 can now connect to each other but nothing really works the way
1573 they are supposed - yet.
1575 * Added new initiator token to RouterConnection configuration
1576 file in silcd/serverconfig.[ch]. It is used to tell whether we
1577 are the initiator to the remote router or whether we'll expect
1578 the other end to connect.
1580 * Moved registering of listener task to silc_server_init, hence
1581 the server starts listenning as soon as it is run, even if it
1582 does not have connections to other routers. Let's see how well
1585 * Changed default connection retry timeouts for more suitable in
1588 * Removed cipher and such arguments from silc_idlist_add_client
1589 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1590 Added new function silc_idlist_add_data to add the keys and stuff
1593 * Added SilcIDListData structure and added it to SilcClientEntry
1594 and SilcServerEntry as their first field in the structure. This
1595 way we can explicitly cast the ID entries to the SilcIDListData
1596 structure and get common data for the entries. In past, we had
1597 to first check what type of connection it is and then cast it to
1598 correct ID entry type. Now, we can directly cast the opaque
1599 pointer to the SilcIDListData (no matter what ID entry it actually
1600 is) and get the data needed.
1602 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1604 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1605 in some circumstances even if threre were timeout tasks, though not
1606 IO tasks, but tasks anyway. Now fixed.
1608 * Defined SilcServerConnection structure to hold connection specific
1609 stuff about directly connected servers and routers. The definition
1610 is currently in silcd/server_internal.h. I thought about having
1611 a bit more important role fro this struct but for now it is used
1612 only when connecting to other server (or router actually).
1614 * Added connecting retry support in server when connecting to
1615 router(s). The retry feature implement exponential backoff
1616 algorithm. Also, added SilcServerParams structure to hold default
1617 parameters for server. For now, it include these retry settings
1618 and are hard coded. After server is moded to be as Silc Server
1619 Library this structure will be more important.
1621 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1623 * Changed client librarys channel->clients table to SilcList and
1624 changed code accordingly.
1626 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1628 * Changed client's channel table to SilcList and changed code
1629 accordingly. Also changed SilcChannelClientEntry to include back-
1630 pointer to the channel so that client entry can use that structure
1631 as list as well and we have fast cross-reference to the channel.
1632 This change dramatically decreased the complexity of channel
1633 handling with client entry and vice versa (removed one extra
1634 loop when searching for channel entry from many functions).
1636 * Changed server->sim from table to SilcDList and changed code
1639 * NAMES command can now be used from user interface. It will show
1640 the user list on the channel, neatly.
1642 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1643 Code now saves realname of the user if it becomes available.
1645 * Renamed configure.in to configure.in.pre and made ./prepare
1646 script to automatically add correct version string to
1647 configure.in which it creates from configure.in.pre.
1649 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1651 * NAMES command reply now shows users mode with the nickname when
1654 * Moved silc_client_ch[u]mode[_char] functions from
1655 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1656 place sucks, they are utility functions and should be in some
1659 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1661 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1664 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1668 * Added TRQ (efficient deque and list library) into lib/trq. This is
1669 a very good list library that is currently used in the SILC. Defined
1670 SilcList API over the library because I didn't like the API very
1671 much. See lib/trq/silclist.h for the API and examples of how to
1672 use the API. Fixed various places in the code to use the new
1673 SilcList API. The SilcList is meant for lists that has a structure
1674 already defined as a list. It is not suitable to add just some
1675 context to the list (in TRQ, the context is the list actually).
1677 So, I defined SilcDList that can be used for the purpose where
1678 predefined list structure does not exit. This can be used as
1679 such list. Now some context just can be added to the SilcDList.
1680 Currently this list is not used in the SILC just yet, though there
1681 are a lot places where this can replace dynamically allocated
1682 tables and I will fix these places, later, to use SilcDList.
1683 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1684 and use TRQ internally).
1686 Also fixed some annoying warning messages that the original TRQ
1687 code generated. Also minor changes to TRQ's Makefile.in.
1689 * Added support for querying by Client ID to both WHOIS and
1690 IDENTIFY commands into server, as required by the protocol.
1692 * Removed method function pointers from SilcBuffer structure. They
1693 weren't used to anything and just increased the context size for
1694 no good reason. This change also made silc_buffer_alloc and
1695 silc_buffer_free functions inline functions.
1697 * Disabled command flooding detection support until it's fixed so
1698 that it accepts commands in but does not execute them more than once
1701 * Added silc_net_localhost(), to return local hostname, into
1702 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1703 that must be initialized before calling silc_client_init.
1705 * Added new function: silc_server_send_notify_on_channels to send
1706 notify messages to all channels client has joined. It is assured
1707 that the message is sent only once per client.
1709 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1710 lib/silcutil/silcutil.[ch] as silc_format function. The new
1711 function is generic and is used by server as well, not only by
1712 the logging routines.
1714 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1715 the provided version string was not acceptable. Added new function:
1716 silc_ske_check_version into lib/silcske/silcske.h. The function
1717 must be implemented by the application (client or server) and it
1718 does not reside in the SKE library. The function checks the version
1719 string remote end sent.
1721 * Added back pointers (to opaque context and to SilcSocketConnection)
1722 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1724 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1725 duplicate packet context structure.
1727 * Changed `notify' client operation to send same arguments as client
1728 receives from server except for ID's. ID's are mapped to correct
1729 ID entry and that is returned. Also, if channel entry is not sent
1730 by server but the notify is for channel the channel entry is sent
1731 to application (otherwise application doesn't know that it is for
1732 channel (library gets it from packet's Destination ID)).
1734 * Added silc_client_remove_from_channels into client library to
1735 remove a client from all channels it has joined to. Used when
1736 received SIGNOFF notify from server. Added also new function
1737 silc_client_replace_from_channels to replace old ID entry with
1738 new ID entry on all channels. Used when received NICK_CHANGE
1741 * Fixed ID Cache list handling in silc_idlist_get_client in
1742 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1743 to get (or query) client by ID.
1745 * Updated TODO list.
1747 * Added connection authentication status message defined by the
1748 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1749 support for these into the code in client and server side.
1751 * Added generic function silc_client_send_command to send any command
1752 with variable argument list. Application should use this function
1753 to send commands if the command functions provided by the library
1754 does not suite for the application's user interface needs.
1756 * Added new `failure' client operation. Application is notified about
1757 received failure packet if client is executing a protocol. In this
1758 case the protocol's execution has failed.
1760 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1761 is required by the protocol.
1763 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1764 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1767 * Added status flag to SilcSKE object to indicate realtime status
1768 of the SKE protocol.
1770 * Application receives now exactly same command reply arguments as
1771 the library receives from server. However, if ID is received the
1772 corresponding ID entry is returned to the application (eg. Client
1773 ID is mapped to correct SilcClientEntry entry and that is returned).
1774 Changed command_reply client operation due to this change.
1776 * Changed all ID's in commands and in command replys as ID Payloads.
1777 Change affected both client and server side codes.
1779 All ID's sent in SILC network (with execption of ID's in SILC
1780 Packet header) are sent in ID Payload to support variable length
1783 * Server now notifies nick changes and notifies all clients on
1784 the channels about the new nickname (about the new Client ID,
1787 * Implemented CMODE command to change channel modes. Supports all
1788 channel modes defined by the protocol specs except ban and invite
1789 lists. (Also, private channel key mode is supported but support for
1790 setting private channel key in client is missing, thus, this mode
1791 has no effect on client side (except that server requires that the
1792 client uses private channel key and normal channel traffic does not
1795 Also, invite mode works per se, but INVITE command does not work
1796 yet correctly, so you can set channel as invite only channel but
1797 inviting clients to the channel does not work (it is yet to be
1798 thought what's the best way to do it).
1800 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1801 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1802 Implemented CUMODE command to change user's mode on the channel.
1803 Supports all modes defined by the protocol specs.
1805 * Added NAMES command reply to return users modes on the channel.
1807 * Removed unnecessary and slow ciphers from lib/silccrypt.
1809 * Set SO_KEEPALIVE option to connection sockets by default.
1811 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1813 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1814 redefined the Notify Payload into protocol specs.
1816 * Added silc_id_payload_parse_id to get ID directly from raw
1819 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1821 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1822 accept searching by Client ID as well.
1824 * Added support for LEAVE and SIGNOFF notify types in client library.
1826 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1827 to parse ID Payload from raw data.
1829 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1831 * Added flags parameter into silc_ske_assemble_security_properties
1832 function in lib/silcske/silcske.[ch].
1834 * Changed notify client operation to fit better for notify messages
1835 sent by server. The notify payload received from server is now
1836 passed to the application (after parsing it to SilcNotifyPayload).
1837 It is application's responsibility to retrieve the arguments
1838 from the payload and show the message the way it wants. The message
1839 sent by server is implementation specific.
1841 * Changed public keys to comply with the protocol specification.
1842 Old public keys are not supported anymore and are not compatible.
1844 * Removed nickname from Channel Payload as the latest draft removed
1845 it. The client must resolve the nickname from the NAMES command
1846 reply received when it joined the channel.
1848 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1850 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1852 * Fixed some errors in protocol specification drafts.
1854 * Created lib/silccore/silcnotify.c to implement Notify Payload
1855 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1856 generic payloads described by protocol specifications. The file
1857 includes implementations for ID Payload and Argument Payload.
1859 * Changed Command Payload implementation to use the new Argument
1860 Payload. Changed command_xxxx_payload to command_payload_xxxx
1861 to comply with SILC coding conventions.
1863 * Added suppport for Argument Payload handling in Notify Payload
1864 implementation as protocol requires it. Added the new support
1865 into server and client lib as well.
1867 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1869 * Added support for multiple nicknames on same channel. [n] is
1870 added locally to the nickname if there are more than one same
1871 nicknames on the channel.
1873 * Server now sends all nicknames that matched WHOIS request.
1874 Client also shows the list received from server.
1876 * Added TOPIC command to client side. User can now set and show
1877 current topic on channel.
1879 * Added MOTD command to client and server. Also, server sends the
1880 motd when client connects to the server.
1882 * Changed version strings to comply ISO 8601.
1884 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1886 * Fixed protocol error handling in client library. It should now
1887 cope even if the SKE fails for some reason.
1889 * Made new protocol specification drafts for submitting to IETF.
1891 * Implemented TOPIC command to server in silcd/command.c.
1893 * Added two new notify types into lib/silccore/silcnotify.h:
1894 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1895 notify nickname change and topic setting/change on a channel.
1897 * API change of command_reply operation in client library. The
1898 application gets now the status type received from server as well.
1900 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1902 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1904 * Cras fixed and optimized the packet handling even further and
1905 it should work now. Minor change to the prototype of function
1906 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1908 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1910 * Added new function into lib/silcutil/silcschedule.[ch]:
1911 silc_schedule_with_fd to select() a specified fd. The function
1912 returns after timeout expires or data arrives or goes. The
1913 function is used by packet routines to wait that all data is
1914 received from network.
1916 * Fixed data reading from network in lib/silccore/silcpacket.c.
1917 The code now assures that all data is read from the fd and then
1918 continues packet processing. This was a bug fix since the code
1919 used to drop some data in some circumstances.
1921 * Added new function into lib/silcclient/client.[ch]:
1922 silc_client_start_key_exchange to start key exchange after
1923 connection has been established to server. The code internally
1924 now uses this funtion but its main purpose was to provide it
1925 for applications that perform their own connecting. After
1926 application has created a connection it merely calls this
1927 function to start the key exchange between client and server.
1928 The library takes care of everything else after that.
1930 Updated also lib/silcclient/README to explain the usage of
1933 * Do not send to application information that connection has
1934 been established. Application gets notified it by connect
1937 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1939 * Applied cras's patch to add silc_schedule_one function. The
1940 function runs scheduler once and returns.
1942 * Fixed the scheduler after cras messed it up. The timeout
1943 handling works now as it's supposed to work.
1945 * Added into lib/silccore/ silcnotify.h to include notify
1946 message types support. Changed silc_server_send_notify*
1947 functions, in server.[ch], to support those new notify types.
1948 Added the support for the notify types into client library,
1949 as well. Added new notify client operation into ops.h in
1952 * Changed silc_server_packet_send_to_channel to send normal
1953 packets instead of just channel message packets. The function
1954 is now used to send the notify packets to channels. It is not
1955 used to send channel message packets anymore, as server never
1958 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1959 va_arg()s as it seems to require it nowadays. I guess, if SILC
1960 is compiled with older va_arg() the new code should work anyway.
1962 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1964 * Splitted core library. Core library (lib/silccore) includes
1965 now only SILC protocol specific core (and common) components.
1966 Created new utility library (lib/silcutil) that includes more
1967 generic purpose stuff. The stuff for util library was taken
1968 from the old core library. This was minor and easy split.
1970 * Created SILC Client Library (lib/silcclient) that includes
1971 implementation of the SILC client without user interface. This
1972 was major move from silc/ directory. The code has been changed
1973 so that it is transparent towards the user interface. The
1974 silc/ directory includes now the same user interface as before
1975 and it uses the new client library. Read lib/silcclient/README.
1976 Basicly, the client library performs everything else related
1977 to SILC except user interface handling. Also, configuration
1978 files are considered to be part of user interface and library
1979 does not handle them.
1981 This change also changed a lot of structures, function naming etc.
1982 Most important change was that SilcClientWindow object was
1983 renamed to SilcClientConnection in the client library. Created
1984 also new file lib/silcclient/ops.h. Also added new files
1985 silc/local_command.[ch] and silc/client_ops.[ch].
1987 All these changes were made to make it easier for user interface
1988 designers to create what ever user interface for the SILC client
1991 It is also expected that the server will be moved to lib
1992 directory as well and SILC Server Library will be created;
1993 sometimes in the future.
1995 * Removed Local commands from lib/silccore/silccommand.h as
1996 they are application specific and new client library does not
1997 handle any of those anymore.
1999 * Several functions moved to lib/silcutil/silcutilc.[ch] from
2000 old client implementation in silc/.
2002 * Added support for callback functions in SILC_LOG_* macros.
2003 Application can now set its own callbacks that will be called
2004 instead of using the default functions that will always print
2005 the debug messages to stderr (or stdout). Also, debugging can
2006 now be disabled by setting silc_debug to FALSE and re-enabled by
2007 setting it to TRUE. Note, that logging will still work even
2008 if debugging is disabled.
2010 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
2011 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
2012 silc_log_reset_debug_callbacks.
2014 * To enable debugging in silc client one must give now -d
2015 option on command line.
2017 * Changed silc_schedule_init to automatically allocate task queues
2018 if they are not allocated before calling it.
2020 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2022 * Added GMP 3.1 into math library.
2024 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2026 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
2027 a channel in SILC network. The packet is used by servers and
2028 routers to notify other routers that user has left a channel.
2029 This little feature was missing until now. Added the feature
2030 to protocol specification as well.
2032 Added functions: silc_server_send_remove_channel_user and
2033 silc_server_remove_channel_user into server.[ch].
2035 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2036 lib/silccore/silcpacket.h. However, they are not implemented
2039 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Fixed joining to a channel and sending channel messages
2042 between server and router. The channel message sending should
2043 now work inside a cell.
2045 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2047 * Fixed the private message sending between server and router.
2048 The private message sending should now work inside a cell.
2050 * Added silc_server_replace_id into server.[ch] to replace
2051 existing ID in the SILC network.
2053 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2054 and silc_idlist_replace_server_id into idlist.[ch] in server.
2056 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2058 * Fixed the server to server connections. Server can again now
2059 connect to router. Router to router connections probably does
2062 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Added dynamic protocol registering support. Now protocols can
2065 registered and unregistered on the fly. Patch by cras.
2067 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2069 * Added lib/contrib directory to hold routines that some platforms
2070 don't have but are needed by SILC.
2072 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2073 into lin/contrib to provide getopt() and getopt_long() for
2074 those who don't have it.
2076 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2078 * Added AWAY command to client. When away message is set and
2079 client receives a private message packet the client automatically
2080 replies to the sender with the away message.
2082 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2083 bug seemed to be the cause of recent problems when compiling
2086 * Added version detection support to SKE protocol specification
2087 and added the new changes to the SKE implementation as well.
2088 There were other minor changes in the SKE protocol as well.
2090 Many changes in lib/silcske/silcske.[ch] and in
2091 lib/silcske/payload.[ch].
2093 * Added ^U functionality, clear input line. Patch from cras.
2095 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2097 * Mainly small bugfixes on core library. Fixed some debugging
2098 logging and buffer overflow in silclog.c.
2100 * Updated config.sub and config.guess on the distribution tree.
2102 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2104 * Added command lagging support in server. Client may execute
2105 commands now only once in two seconds.
2107 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2109 * Optimized packet reception. MAC computation and checking is now
2110 also more optimized. A lot previously duplicated code is now
2111 used as generic by both client and server.
2113 * Fixed key pair generation in clientutil.c
2115 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2117 * Added into lib/silccore/silcbufutil.[ch] new function;
2118 silc_buffer_realloc.
2120 * Moved generic packet sending/encryption functions to
2121 lib/silccore/silcpacket.[ch] from client and server. Some
2122 rewriting of the functions.
2124 * Moved all generic packet reception/decryption functions to
2125 lib/silccore/silcpacket.[ch] from client and server. The
2126 packet processing is now much cleaner in both client and server.
2127 These were major changes in both client and server.
2129 * Created many common functions in server to do packet sending.
2130 Previously code were duplicated a lot, this has been removed
2133 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2135 * Rewrote major parts of the ID cache system. Don't know
2136 whether it is better now or not but at least the API is more
2139 * Major rewrite on ID cache stuff on client because of the ID
2140 cache API changes. Added idlist.c to client.
2142 * Also major rewrite on ID cache stuff on server as well.
2143 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2144 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2145 in hand, instead they are all put into the ID cache system now.
2146 All server_idlist_* routines uses ID cache now instead of
2147 traversing its own lists (those lists does not exist anymore).
2148 SilcIDList though still exists. Also, SilcXXXEntry's are
2151 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2153 * Finally made the SKE implementation compliant to the protocol
2154 specification. All mp integers are now binary encoded as
2155 opposed being HEX encoded.
2157 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2160 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2161 functions: silc_[encode/decode]_pem. Also added function
2162 silc_encode_pem_file to PEM encode with newlines ('\n') for
2165 * SILC public keys are now encoded either PEM or binary. Same
2166 option is for private keys as well. By default private keys
2167 are binary encoded and public keys PEM encoded. Silly HEX
2168 encoding were removed.
2170 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2171 function to create fingerprints.
2173 * Fixed a bug in SHA1; does not change the original data anymore.
2175 * Partly implemented INFO command on client and server side.
2176 Fixed CLEAR command. Changes to SERVER command; show current
2177 server(s) when giving command without arguments. Added
2178 VERSION command to client.
2180 * Added check to server that unregistered connections cannot
2181 execute commands (unless it is specificly allowed).
2183 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2185 * Fixed screen refresh.
2187 * Fixed channel joining bug from client. On some circumstances
2188 client tried to join to a channel it had already joined.
2190 * Added public key verification process into client's protocol.c.
2191 The client now verifies the public key from user and saves
2192 it into ~./silc/serverkeys/ directory.
2194 Added into: clientutil.[ch]: silc_client_verify_server_key.
2196 * Changed SKE protocol's silc_ske_initiator_finish function
2197 to accept callback function that verifies the received public
2198 key. Removed old silc_ske_verify_public_key function.
2200 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2202 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2203 silc_pkcs_private_key[_data]_set.
2205 * Made the password and public authentication more cleaner in
2206 server's protocol.c.
2208 * Removed historic and obsolete protocol `channel_auth' from
2209 both client and server.
2211 * Removed wrong way of sending command status messages from
2212 server to client in server's command.c. The old way violated
2213 protocol specification.
2215 Changes to silccore/silccommand.[ch]: removed
2216 silc_command_encode_status_payload -> not needed anymore,
2217 changed silc_command_encode_payload_va to accept extra
2218 argument on variable argument list. The argument type must
2219 now be provided to the function. Also, added new function:
2220 silc_command_encode_reply_payload_va which is same as
2221 normal command_encode_payload_va except command status type
2222 is provided as extra argument.
2224 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2226 * Added ~./silc directory handling. The directory includes the
2227 public and private keys for the client.
2229 Added silc_client_check_silc_dir, silc_client_create_identifier
2230 and silc_client_load_keys.
2232 * Implemented SILC protocol compliant public key. Added public
2233 and private key saving to and loading from files.
2235 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
