1 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Server now enforces the maximum length for the nickname and
4 the channel as protocol specification dictates. 128 bytes for
5 nickname and 256 bytes for channel name.
7 * Moved the WHOIS printing to the application. The client libary
8 does not print out the WHOIS information anymore, the application
9 must do it. Renamed silc_client_command_reply_whois_print to
10 the silc_client_command_reply_whois_save.
12 The client's idle time is also sent to the application now, and
13 the idle is shown on screen.
15 * Added silc_client_command_reply_identify_save to save the
16 received IDENTIFY entries.
18 * Do not check for channel private keys in message sending and
19 reception if the channel does not have the PRIVKEY mode set.
20 Affected file lib/silclient/client_channel.c.
22 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
24 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
25 just surfaced after chaning the JOIN procedure.
27 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
29 * Added silc_client_get_clients_by_list to get client entries
30 from Client ID list, that is returned for example by JOIN
31 and USERS command replies. The application should use this
32 function for example when JOIN command reply is received to
33 resolve the clients already on the channel (library does not
34 do that anymore as USERS command reply is not used in the JOIN
35 procedure anymore). Affected files lib/silcclient/silcapi.h and
36 lib/silcclient/idlist.c.
38 * JOIN command reply and USERS command reply returns now SilcBuffer
39 pointers instead of unsigned char pointers when returning
40 the client list and mode list.
42 * Added <Client ID> argument to the JOIN command reply, mainly
43 for the server to identify for which client the command was
44 originally sent. Updated protocol specs accordingly.
46 * Added SilcDlist private_key pointer to the SilcChannelEntry
47 in the client to support the channel private keys. Affected
48 file is lib/silcclient/idlist.h.
50 * Added SilcChannelPrivateKey argument to the function
51 silc_client_send_channel_message so that application can choose
52 to use specific private ke if it wants to. If it is not provided,
53 the normal channel key is used, unless private keys are set.
54 In this case the first (key that was added first) is used
55 as the encryption key.
57 * Implemented the support for channel private key handling.
58 Implemented the following functions:
60 silc_client_add_channel_private_key,
61 silc_client_del_channel_private_keys,
62 silc_client_del_channel_private_key,
63 silc_client_list_channel_private_keys and
64 silc_client_free_channel_private_keys
66 Affected file lib/silcclient/client_channel.c.
68 * Added the support for the private keys in the channel message
69 sending and encryption and in the message reception and
70 decryption. Affected funtions are
71 silc_client_send_channel_message and silc_client_channel_message.
73 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
75 * Added SKE's key verify callback to the client library's
76 KE protocol context. Affected files lib/silcclient/protocol.[ch].
78 * Removed the statement that server (or router) must send USERS
79 command reply when joining to the channel so that the client
80 knows who are on the channel. Instead, the client list and
81 client's mode list is now sent in the JOIN command reply to the
82 client who joined channel. This is better solution.
84 * Added function silc_server_get_users_on_channel and function
85 silc_server_save_users_on_channel to the silcd/server.[ch].
87 * Removed function silc_server_command_send_users from the
90 * Do not show topic on the client library anymore. The topic is
91 sent in the command reply notify to the application and the
92 application must show the topic now.
94 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
96 * Added client searching by nickname hash into the IDENTIFY and
97 WHOIS commands in the server as they were clearly missing from
98 them. Affected file is silcd/command.c.
100 * Fixed a bug in private message receiving in the client library.
101 The remote ID was freed and it wasn't supposed, now it is
104 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
106 * Minor fix to the channel payload; allocate the data area, as it
107 needs to be of specific length.
109 * If the key agreement port is zero then the operating
110 system will define the bound port. Affected files are
111 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
113 * Added new function silc_channel_payload_decrypt into the file
114 lib/silccore/silcchannel.[ch].
116 * Moved the channel message etc, check from silc_packet_decrypt
117 to applications. The library calls now a generic
118 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
119 when the packet is either normal or special. This was done to
120 allow more wide range of checking that was not allowed when
121 the code was in library. Now applications can do virtually any
122 checks to the packet and return to the library the decision how
123 the packet should be processed. Affected files are
124 lib/silccore/silcpacket.[ch].
126 Added silc_server_packet_decrypt_check to the server and
127 silc_client_packet_decrypt_check to the client library.
129 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
130 to send with specified source and destination information.
132 * Channel message delivery between routers was broken after the
133 channel key distribution was fixed earlier. The channel key
134 was used be to distributed to other routers as well which is not
135 allowed by the protocol. Now this is fixed and channel keys
136 really are cell specific and the channel message delivery between
137 routers comply with the protocol specification.
139 * Fixed various commands in server to check also the global list
140 for the channel entry and not just the local list. The affected
141 file silcd/command.c.
143 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
145 * Added assert()s to buffer formatting and unformatting routines
146 to assert (if --enable-debug) when error occurs. Affected
147 file: lib/silcutil/silcbuffmt.c.
149 * Changed to auto-reconnect to check whether the remote host is
150 router and register the re-connect timeout if it is. It used
151 to check that whether we are normal server, but router must do
152 auto-reconnect with another router as well. Affected file
155 * Removed the [<key len>] option from CMODE command as the cipher
156 name decides the key length, nowadays. See the defined ciphers
157 from the protocol specification.
159 * Added [<hmac>] option to the CMODE command to define the HMAC
160 for the channel. Added SILC_CMODE_HMAC channel mode.
162 * Added [<hmac>] option for the JOIN command so that user can
163 select which HMAC is used to compute the MACs of the channel
166 * Added Hmac field to the Channel Message Payload. The integrity
167 of plaintext channel messages are now protected by computing
168 MAC of the message and attaching the MAC to the payload. The
169 MAC is encrypted. Now, it is clear that this causes some
170 overhead to the size of the packet but rationale for this is that
171 now the receiver can verify whether the channel message decrypted
172 correctly and also when private keys are set for the channel the
173 receiver can decrypt the packet with several keys and check from
174 the MAC which key decrypted the message correctly.
176 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
177 lib/silccrypt/silccipher.[ch].
179 * Added silc_hash_len to return the digest length into the
180 lib/silcrypt/silchash.[ch].
182 * Rewrote parts of Silc Channel Payload interface in the
183 lib/silccore/silcchannel.[ch]. The encode function now also
184 encrypts the packet and parse function decrypts it.
186 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
188 * Fixed a minor formatting bug in the SKE's key material processing.
189 It actually might have processed the keys wrong way resulting
192 * Redefined the mandatory HMAC algorithms and added new algorithms.
193 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
194 and hmac-md5 truncated to 96 bits. The mandatory is now
195 hmac-sha1-96. Rest are optional (including the one that used
196 to be mandatory). Rationale for this is that the truncated HMAC
197 length is sufficient from security point of view and can actually
198 make the attack against the HMAC harder. Also, the truncated
199 HMAC causes less overhead to the packets. See the RFC2104 for
202 * Added new [hmac] configuration section. The SKE used to use
203 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
204 is of course wrong. The official names that must be proposed in
205 the SKE are the ones defined in the protocol specification
206 (hmac-sha1-96 for example). The user can configure any hmac
207 using any hash function configured in the [hash] section. At
208 least, the mandatory must be configured.
210 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
212 * Added HMAC list to the SKE proposal list. It has now both
213 hash algorithm list and HMAC list. This makes the protocol
214 incompatible with previous versions. The SKE now seems to work
215 the way it is supposed to work, for the first time actually.
217 * Defined plain Hash algorithms to the protocol specification.
220 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
222 * Implemented support for key agreement packets into the server.
223 Added functions silc_server_key_agreement and
224 silc_server_send_key_agreement. Other than these functions,
225 server has nothing to do with this packet.
227 * Added support for private message key packets into the server.
228 Added functions silc_server_private_message_key and
229 silc_server_send_private_message_key.
233 * Changed the silc_[client|server]_protocol_ke_set_keys to be
234 called in the protocol's final callback instead in the END
235 protocol state. This makes a little more sense and in the same
236 time in client we can use the same protocol routines for normal
237 key exchange and to key agreement packet handling as well.
239 * Added to both client's and server's KE protocol context the
240 SilcSKEKeyMaterial pointer to save the key material. We will
241 bring the key material to the protocol's final callback by doing
242 this. The final callback must free the key material.
244 * Added SKE's packet_send callback into client's KE protocol
245 context so that the caller can choose what packet sending function
246 is used. This way we can use different packet sending when
247 doing normal SKE when doing key agreement packet handling (in
248 the key agreement packet handling we do not want to encrypt
251 * Implemented the responder side of the key agreement routines
252 in the client. The client can now bind to specified port and
253 accept incoming key negotiation. The key material is passed
254 to the application after the protocol is over.
256 * Implemented the processing of incoming Key Agreement packet
257 in the client. Added function silc_client_key_agreement to
260 * Implemented the intiator side of the key agreement routines
261 in the client. The client can now initiate key agreement with
262 another remote client. The key material is passed to the
263 application after the protocol is over.
265 * Created client_keyagr.c to include all the key agreement
268 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
269 SILC_TASK_CALLBACK except that it is not static.
271 * Created client_notify.c and moved the Notify packet handling
272 from the client.[ch] into that file.
274 * Created client_prvmsg.c and moved all private message and
275 private message key routines from the client.[ch] into that file.
277 * Create client_channel.c and moved all channel message and
278 channel private key routines from the client.[ch] into that file.
280 * Changed silc_client_get_client_by_id_resolve to resolve with
281 WHOIS command instead of IDENTIFY command, in the file
282 lib/silclient/idlist.c.
284 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
286 * Implemented the SKE's responder side to the Client library.
288 * When FAILURE is received to the protocol do not trust it
289 blindly. Register a timeout to wait whether the remote closes
290 the connection as it should do it, only after that process the
291 actual failure. This was changed to both client and server.
293 * Added client_internal.h to include some of the structures
294 there instead of client.h in lib/silcclient/.
296 * Added function silc_task_unregister_by_callback to unregister
297 timeouts by the callback function.
299 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
301 * Some "Incomplete WHOIS info" errors has been appearing on the
302 log files. Took away the entry->userinfo check from WHOIS
303 reply sending. The entry->userinfo is now " " if client did not
304 provide one. I thought this was fixed earlier but something
305 is wrong still. Let's see if the error still appears.
307 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
309 * Fixed a minor bug in the login when the channel key is
310 re-generated in the server. It used to generate the key in
311 wrong order and thus caused problems in the channel traffic.
313 * Fixed a minor bug in channel key distsribution after
314 KICK command. The key was not sent to the router even though
317 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
319 * Added silc_ske_process_key_material_data as generic routine
320 to process any key material as the SILC protocol dictates. The
321 function is used by the actual SKE library but can be used by
322 applications as well. This relates to the private message keys
323 and the channel private keys since they must be processed the
324 same way the normal SILC session keys. The protocol dictates
325 this. Affected files: lib/silcske/silcske.[ch].
327 Added also silc_ske_free_key_material to free the
328 SilcSKEKeyMaterial structure.
330 * Defined silc_cipher_set_key function to set the key for
331 cipher without using the object's method function. The affected
332 files: lib/silccrypt/silccipher.[ch].
334 * Implemented silc silc_client_add_private_message_key,
335 silc_client_add_private_message_key_ske,
336 silc_client_del_private_message_key,
337 silc_client_list_private_message_keys and
338 silc_client_free_private_message_keys functions in the
341 Added functions silc_client_send_private_message_key to send
342 the Private Message Key payload and silc_client_private_message_key
343 to handle incoming Private Message Key payload.
345 * Added Cipher field to the Private Message Key payload to set
346 the cipher to be used. If ignored, the default cipher defined
347 in the SILC protocol (aes-256-cbc) is used.
349 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
351 * Removed lib/silcclient/ops.h file.
353 Redefined parts of the SILC Client Library API. Created new
354 file silcapi.h that deprecates the ops.h file and defines the
355 published Client Library API. Defined also private message key
356 API and channel private key API into the file.
358 This is the file that the application must include from the
359 SILC Client Library. Other files need not be included by
360 the application anymore.
362 * Added new key_agreement client operation callback and also
363 defined the Key Agreement library API for the application.
365 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
367 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
368 is used by clients to request key negotiation between another
369 client in the SILC network. If the negotiation is started it
370 is performed using the SKE protocol. The result of the
371 negotiation, the secret key material, can be used for example
372 as private message key.
374 Implemented the Key Agreement payload into the files
375 lib/silccore/silauth.[ch].
377 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
379 * Redefined ciphers for the SILC protocol. Added some new ciphers
380 and defined the key lengths for the algorithms. Changed the
381 code accordingly. The default key length is now 256 bits.
383 * Fixed SKE key distribution function silc_ske_process_key_material
384 when the key length is more than 128 bits. The default key
385 length in SILC is now 256 bits.
387 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
388 to indicate unsupported algorithm.
390 * Renamed rijndael.c to aes.c and all functions as well.
392 * Fixed a long standing channel key setting bug in client library.
393 Weird that it has never surfaced before.
395 * Fixed bug in channel deletion. If the entire channel is removed
396 then it must also delete the references of the channel entry
397 from the client's channel list as the client's channel entry and
398 the channel's client entry share same memory.
400 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
402 * Implemented CONNECT and SHUTDOWN commands in the client.
404 * Implemented CLOSE command to the client.
406 * Added the function silc_idlist_find_server_by_name into the
407 files silcd/idlist.[ch].
409 Added the function silc_idlist_find_server_by_conn into the
410 files silcd/idlist.[ch].
412 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
414 * DIE command was renamed to SHUTDOWN. Updated the both code
417 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
418 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
420 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
423 * Added function silc_server_create_connection function to create
424 connection to remote router. My server implementation actually
425 does not allow router to connect to normal server (it expects
426 that normal server always initiates the connection to the router)
427 so the CONNECT command is only good for connecting to another
430 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
432 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
433 or some other client was kicked from the channel.
435 Implemented the handling of the notify type to both client
438 Implemented silc_server_send_notify_kicked to send the KICKED
439 notify. It is used to send it to the server's primary router.
441 * Implemented the KICK command into server and client.
443 * Added `query' argument to the silc_idlist_get_client function
444 to indicate whether to query the client from server or not if
447 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
448 to indicate that the client is not channel founder.
452 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
454 * Removed the rng context from SilcPacketContext structure and
455 changed that the packet routine uses the Global RNG API.
457 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
459 * Added support for quit message that client can "leave" on the
460 channel when it quits the SILC. It is ditributed inside the
461 SILC_NOTIFY_TYPE_SIGNOFF notify type.
463 Added silc_server_free_client_data that will take the
464 signoff message as argument.
466 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
468 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
470 * Updated parts of the protocol specification to keep it up
473 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
475 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
476 payloads in one packet.
478 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
479 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
480 use now the new List flag.
482 * Also deprecated the following packet types: REPLACE_ID,
483 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
485 * Added list support for Notify packet in server.
487 * Added silc_server_send_notify_channel_change to send the
488 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
489 the silc_server_send_replace_id.
491 * Added silc_server_send_notify_nick_change to send the
492 NICK_CHANGE notify type. Deprecates the function
493 silc_server_send_replace_id.
495 * Added silc_server_send_notify_join to send the JOIN notify type.
496 Deprecates the function silc_server_send_new_channel_user.
498 * Added silc_server_send_notify_leave to send LEAVE notify type.
499 Deprecates the function silc_server_send_remove_channel_user.
501 * Added silc_server_send_notify_cmode and
502 silc_server_send_notify_cumode to send CMODE and CUMODE notify
503 types. Deprecates the silc_server_send_set_mode function.
505 * Added SERVER_SIGNOFF notify type to indicate that server has
506 quit. This means that all clients on the channel from that
507 server will drop. This can be also used when netsplit happens.
509 Deprecated REMOVE_ID packet type since it is not needed anymore
512 Added silc_server_send_notify_server_signoff to send the
513 SERVER_SIGNOFF notify type. Deprecates the function
514 silc_server_send_remove_id.
516 Added also silc_server_send_notify_signoff to send the
519 * Employed the PKCS #1. It is the mandatory way to do RSA in the
520 SILC protocol from this day on. Changed the protocol
521 specification as well.
523 * Added silc_server_send_notify_topic_set to send TOPIC_SET
524 notify type. It is used between routers to notify about
525 topic changes on a channel.
527 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
530 * Partly updated the protocol specification to comply with the
531 changes now made. It is still though a bit outdated.
533 * The JOIN notify type now takes one extra argument <Channel ID>.
534 The packet used to be destined to the channel but now the
535 JOIN type may be sent as list thus it is impossible to
536 destine it to any specific channel. By adding this argument
537 it is again possible.
539 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
541 * Added CREDITS file. The CHANGES and CREDITS file will appear
542 in the distribution as well.
544 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
546 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
547 types in the server's silcd/packet_receive.c.
549 * Implemented CMODE and CUMODE to work in router environment.
551 * Fixed minor encoding and decoding buglet from the
552 lib/silccore/silcmode.c.
554 * Fixed buffer overflow from lib/silcclient/command.c in USERS
557 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
559 * Changed all SilcConfigServer* and silc_config_server* to
560 SilcServerConfig* and silc_server_config*, respectively.
563 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
565 * Associated the ID (client or server ID) to the Authentication
566 Payload to avoid any possibility of forging. Updated the
567 protocol specification and the code accordingly.
569 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
571 * The RSA key length is now save to the RsaKey context in the
572 key generation process in lib/silccrypt/rsa.c. The key length
573 is now used to figure out the maximum size of the block allowed
574 to be encrypted/signed.
576 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
577 is equivalent to the silc_mp_mp2bin but does not allocate any
580 * Changed silc_mp_mp2bin API to take length argument. If it is
581 non-zero then the buffer is allocated that large. If zero, then
582 the size is approximated using silc_mp_sizeinbase, which however
585 * Created Global RNG API which is global RNG that application can
586 initialize. After initializing, any routine anywhere in the
587 code (including library) can use RNG without allocating a new
588 RNG object. This was done to allow this sort of use of the
589 RNG in code that has no chance to allocate RNG object. All
590 applications currently allocate this and many routines in the
591 library use this. Affected file lib/silccrypt/silcrng.[ch].
593 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
594 it to use the Global RNG API.
596 * Defined Authentication Payload into protocol specification that
597 is used during SILC session to authenticate entities. It is
598 used for example by client to authenticate itself to the server
599 to obtain server operator privileges.
601 Implemented this payload into the lib/silccore/silcauth.[ch].
602 Implemented also routines for public key based authentication
603 as the new protocol specification dictates.
605 Moved definitions of different authentication methods from
606 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
608 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
609 silc_pkcs_verify and silc_pkcs_sign_with_hash and
610 silc_pkcs_verify_with_hash functions into the file
611 lib/silccrypt/silcpkcs.[ch].
613 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
615 * The client entry's userinfo pointer must be always valid.
616 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
617 will fail since it requires the userinfo. Now, the userinfo
618 is allocated as "" if actual userinfo does not exist. Actually,
619 it must exist and it is totally Ok to drop client connections
620 that does not announce the userinfo. However, we will make
621 this workaround for now.
623 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
624 to return the remote port by socket.
626 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
628 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
629 SILC_SERVER_PENDING_EXEC and added an new macro
630 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
631 data or when error occurs while processing the pending command.
633 Added new argument `destructor' into silc_server_command_pending
634 and to the SilcServerCommandPending object. This destructor is
635 now called after calling the pending callback or if error occurs
636 immediately. If error occurs the actual pending callback won't
637 be called at all - only the destructor. The destructor may be
638 NULL if destructor is not needed.
640 All this applies for client library code as well. Similar
641 changes were made there as well for the pending commands.
643 In the client, the application must now allocate the
644 SilcClientCommandContext with the silc_client_command_alloc
647 * Added reference counter to the SilcServerCommandContext. Added
648 function silc_server_command_alloc and silc_server_command_dup
651 Same type of functions added to the client library for the same
654 * Removed the cmd_ident from IDListData away since it is now
655 global for all connections. It is the command identifier used
656 in command sending and with pending commands. The affected file
659 * Added reference counter to the SilcSocketConnection objecet to
660 indicate the usage count of the object. The object won't be
661 freed untill the reference counter hits zero. Currently only
662 server uses this, and client ignores it. The client must be
663 set to use this too later. The affected files are
664 lib/silccore/silcsockconn.[ch]. Added also the function
665 silc_socket_dup to increase the reference counter.
667 This was mainly added because it is possible that the socket
668 is removed underneath of pending command or other async
669 operation. Now it won't be free'd and proper DISCONNECTING
670 flags, etc. can be set to avoid sending data to connection that
671 is not valid anymore.
673 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
674 the connection. After that it sets SILC_SET_DISCONNECTED.
675 It is, however, possible that the socket data is not still freed.
676 The silc_server_packet_process now checks that data is not
677 read or written to connection that is DISCONNECTED. The socket
678 get's freed when the reference counter hits zero.
680 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
682 * Changed the client operation API: channel_message operation's
683 `sender' is now the client entry of the sender, not the nickname
684 and the `channel' is the channel entry, not the channel name.
686 In the private_message operation the `sender' is now also the
687 client entry of the sender not the nickname.
689 Affected file is lib/silcclient/ops.h and all applications
690 using the client operations.
692 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
694 * Moved the calling of ops->connect() from connect_to_server_final
695 into receive_new_id functin since that is the point when the
696 client is actually allowed to send traffic to network. The
697 affected file is lib/silcclient/client.c.
699 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
701 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
702 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
703 (if needs broadcasting) instead of broadcasting the packets one
704 by one which would make a burst in the network traffic.
706 * Added `broadcast' argument to the functions in silcd/server.[ch]
707 silc_server_create_new_channel[_with_id] to indicate whether
708 to send New Channel packet to primary router.
710 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
712 * Added new function into the silcd/server.[ch] files:
713 silc_server_create_new_channel_with_id to create new channel with
714 already existing Channel ID.
716 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
717 lib/silccore/silcpacket.h. This packet is used t send list of
718 Set Mode payloads inside one packet. Server uses this to set
719 the modes for the channels and clients on those channels, that it
720 announced to the router when it connected to it. The protocol
721 specification has been updated accordingly.
723 * The silc_server_new_channel did not handle the packet coming
724 from normal server as it normally does not send that. However,
725 when it announces its channels it does send it. Implemented
726 the support for that.
728 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
729 into the file lib/silccore/id.h.
731 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
733 * Fixed memory leaks in the functions silc_idlist_del_client,
734 silc_idlist_del_channel and silc_idlist_del_server in the file
735 silcd/idlist.c. All of those leaked like a sieve.
737 * Fixed some small memory leaks in the client's function
738 silc_client_notify_by_server.
740 * Added functions into silcd/server.c: silc_server_announce_clients,
741 silc_server_announce_channels and silc_server_announce_server.
742 These functions are used by normal and router server to announce
743 to its primary router about clients, channels and servers (when
744 router) that we own. This is done after we've connected to the
747 These functions effectively implements the following packet types:
748 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
749 and SILC_PACKET_NEW_ID_LIST.
751 * Added new functions into the silcd/packet_receive.[ch]:
752 silc_server_new_id_list, silc_server_new_channel_list and
753 silc_server_new_channel_user_list to handle the incoming
754 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
756 * Added support of changing Channel ID in the function
757 silc_server_replace_id. If the server that announces a channel
758 to the router already exists in the router (with same name but
759 with different Channel ID), router is responsible to send
760 Replace ID packet to the server and force the server to change
761 the Channel ID to the one router has.
763 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
764 client that the Channel ID has been changed by the router. The
765 normal server sends this to the client. Client must start using
766 the new Channel ID as the channel's ID.
768 Implemented handling of this new type into lib/silcclient/client.c
769 into the function silc_client_notify_by_server.
771 * Added new function silc_idlist_replace_channel_id into the files
772 silcd/idlist.[ch] to replace the Channel ID.
774 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
776 * Call silc_server_command_identify_check always when processing
777 the IDENTIFY command in silcd/command.c
779 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
781 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
782 send keepalive packets. The packet can be sent by clients,
785 Added function silc_socket_set_heartbeat into the file
786 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
787 If not set, the heartbeat is not performed. The actual
788 heartbeat is implemented in the low level socket connection
789 library. However, application is responsible of actually
792 Added silc_server_send_heartbeat to send the actual heartbeat
793 packet into silcd/packet_send.[ch]. Server now performs
794 keepalive with all connections.
796 * Added silc_task_get_first function into lib/silcutil/silctask.c
797 to return the timeout task with shortest timeout. There was a bug
798 in task unregistration that caused problems. TODO has been
799 updated to include that task system must be rewritten.
801 * The client library will now resolve the client information when
802 receiving JOIN notify from server for client that we know but
803 have incomplete information.
805 * Rewrote parts of silc_server_remove_from_channels and
806 silc_server_remove_from_one_channel as they did not remove the
807 channel in some circumstances even though they should've.
809 * Encryption problem encountered in server:
811 The LEAVE command used to send the Channel Key packet to the
812 router immediately after generating it. However, the code
813 had earlier sent Remove Channel user packet but not immediately,
814 ie. it was put to queue. The order of packets in the router
815 was that Channel Key packet was first and Remove Channel User
816 packet was second, even though they were encrypted in the
817 reverse order. For this reason, MAC check failed. Now, this
818 is fixed by not sending the Channel Key packet immediately but
819 putting it to queue. However, this is more fundamental problem:
820 packets that are in queue should actually not be encrypted
821 because packets that are sent immediately gets encrypted
822 actually with wrong IV (and thus MAC check fails). So, packets
823 that are in queue should be encrypted when they are sent to
824 the wire and not when they put to the queue.
826 However, the problem is that the current system has not been
827 designed to work that way. Instead, the packet is encrypted
828 as soon as possible and left to the queue. The queue is then
829 just purged into wire. There won't be any fixes for this
830 any time soon. So, the current semantic for packet sending
833 o If you send packet to remote host and do not force the send
834 (the packet will be in queue) then all subsequent packets to the
835 same remote host must also be put to the queue. Only after the
836 queue has been purged is it safe again to force the packet
839 o If you send all packets immediately then it safe to send
840 any of subsequent packets through the queue, however, after
841 the first packet is put to queue then any subsequent packets
842 must also be put to the queue.
844 Follow these rules and everything works fine.
846 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
848 * Added new function silc_server_remove_clients_by_server to
849 remove all client entries from ID list when the server connection
850 is lost. In this case it is also important to invalidate all
851 client entires as they hold the invalid server entry. This
852 fixes fatal bug when server has lost connection and will reconnect
855 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
857 * Made some sanity checks to silc_server_daemonise like to check
858 whether the requested user and group actually exists.
860 * Added sanity check to SKE's silc_ske_responder_finish to check
861 that the public and private key actually is valid.
863 * Invalidate the client's nickname when receiving Replace ID
864 packet and the Client ID is being replaced. This means that the
865 server will query the nickname if someone needs it (client)
868 * Sort the ID Cache in client library when the ID Cache data
869 has changed (needs sorting).
871 * Do not allow for SILC client to create several connections to
872 several servers. The client does not support windows right now
873 and generating multiple connections causes weird behaviour.
875 Irssi-silc client does support windows and can handle several
876 connections without problems, see: www.irssi.org and SILC plugin.
878 * Fixed some places where client was added to the IDList. The
879 rule of thumb is following (in order to get everything right):
880 If the client is directly connected local client then the
881 `connection' argument must be set and `router' argument must be
882 NULL to silc_idlist_add_client function. If the client is not
883 directly connected client then the `router' argument must
884 bet set and the `connection' argument must be NULL to the
885 silc_idlist_add_client function.
887 * The funtion silc_server_packet_send_local_channel actually did
888 not check whether the client was locally connected or not. It
889 does that now. Fixed a bug related to LEAVE command.
891 * Fixed Remove Channel User payload parsing bug in server's
892 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
894 * The server's silc_server_save_channel_key now checks also the
895 global ID list for the channel as it might not be in the local
896 list. Fixed a bug related to LEAVE command.
898 * Is this the end of the [<unknown>] buglet that has been lurking
899 around for a long time? A little for loop fix in server's
900 silc_server_command_whois_parse that is used by both IDENTIFY
901 and WHOIS command. At least, this was a clear bug and a cause
902 of one type of [<unknown>] buglet.
904 * WHOIS and IDENTIFY commands call the function
905 silc_server_command_[whois/identify]_check function even if
906 we are not router server.
908 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
910 * Added --with-gmp configuration option. If set the GMP
911 is always compiled in the SILC source tree. If not set then
912 it is checked whether the system has the GMP3 installed. If
913 it has then the GMP won't be compiled (the system's headers
914 and library is used), if it doesn't have it then the GMP is
915 compiled in the SILC source tree.
917 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
919 * Changed RSA private exponent generation to what PKCS #1
920 suggests. We try to find the smallest possible d by doing
921 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
922 not security fix but optimization.
924 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
926 * Added new config entry [Identity] to fork the server and run
927 it as specific user and group. A patch from Bostik.
929 * Imported Dotconf configuration library into lib/dotconf.
930 This will be used to create the SILC configuration files later.
931 It will appear in the distsribution after this commit.
933 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
935 * A big code auditing weekend happening. Auditing code for
936 obvious mistakes, bugs and errors. Also, removing any code
939 Removed files for being obsolete:
941 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
942 inline in the file lib/silcutil/silcbuffer.h)
944 o lib/silcutil/silcbufutil.c (the header has inline versions)
946 Changed code to fix possible error conditions:
948 o The buffer formatting routines now check that the destination
949 buffer really has enough space to add the data. This applies for
950 both buffer formatting and unformatting
951 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
952 unformatting was changed to accomodate following rules:
953 XXX_*STRING_ALLOC will allocate space for the data into the pointer
954 sent to the function while XXX_*STRING will not allocate or copy
955 the data into the buffer. Instead it sets the pointer from the
956 buffer into the pointer sent as argument (XXX_*STRING used to
957 require that the pointer must be allocated already). This change
958 makes this whole thing a bit more consistent and more optimized
959 (note that the data returned in the unformatting with XXX_*STRING
960 must not be freed now). The routines return now -1 on error.
962 o Tried to find all code that use buffer_format and buffer_unformat
963 and added return value checking to prevent formatting and
964 especially unformatting errors and possible subsequent fatal
967 o Changed ske->x and ske->KEY to mallocated pointers in
968 lib/silcske/silcske.h. Fixed possible data and memory leak.
970 o Added return value checking to all *_parse* functions. Fixed
971 many memory leaks as well.
973 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
974 so that buffer overflows would not happen. All code now also
975 checks the return value as it can fail.
977 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
979 * Added reconnection support to server if the normal server looses
980 its connection to the router (for example if router is rebooted).
981 The server performs normal reconnection strategy implemented
982 to the server. Affected file silcd/server.c.
984 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
986 * Added new packet type SILC_PACKET_SET_MODE that is used to
987 distribute the information about changed modes (for clients,
988 channels and clients channel modes) to all routers in the
989 network. Updated the protocol specification accordingly.
991 Added functions into silcd/packet_send.c and
992 silcd/packet_receive.c: silc_server_send_set_mode,
993 silc_server_set_mode.
995 Added new files silcmode.[ch] into lib/silccore that implements
996 the encoding and decoding of Set Mode Payload. Added new type
997 SilcSetModePayload. Moved the definitions of different modes
998 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1000 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1002 * Oops, a little mistake in server's connection authentication
1003 protocol. The protocol is not ended with FAILURE but with
1004 SUCCESS if the authentication is Ok. :) Affected file is
1007 * Implemented NICK_CHANGE notify handling in server in the file
1008 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1009 the local clients on the channel. After the changing nickname
1010 in router environment snhould work and the [<unknown>] nickname
1011 should appear no more.
1013 The silc_server_replace_id function that receives the Replace ID
1014 payload now sends the NICK_CHANGE notify type also in the file
1015 silcd/packet_receive.c
1017 * Changed WHOIS and IDENTIFY command to support the maximum amount
1018 of arguments defined in protocol specs (3328 arguments). This
1019 fixed a bug that caused problems when there were more than three
1022 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1024 * Added extra parameter, command identifier, to the
1025 silc_client_send_command so that explicit command identifier
1028 Changed that ID list routines uses specific command identifier
1029 when sending WHOIS/IDENTIFY requests to the server so that they
1030 can be identified when the reply comes back.
1032 Affected files lib/silcclient/command.[ch],
1033 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1035 * Added `sender' argument to silc_server_packet_send_to_channel
1036 to indicaet the sender who originally sent the packet to us
1037 that we are now re-sending. Ignored if NULL. Affected file
1038 silcd/packet_send.[ch].
1040 * Added some server statistics support in silcd/server_internal.h
1041 SilcServerStatistics structure and around the server code. Also
1042 send some nice statistics information when client is connecting
1045 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1047 * Fixed channel ID decoding in server's JOIN command reply in
1048 silcd/command_reply.c
1050 * Fixed braodcasting of replace ID payload to not to send it if
1051 we are standalone server in silcd/packet_receive.c.
1053 * Fixed all channel message sending routines to not to send
1054 packets to clients that has router set, since they are routed
1055 separately in the same function earlier. Affects file
1056 silcd/packet_send.c and all channel packet sending functions.
1058 * In USERS reply, res_argv[i] are not allocated, the table
1059 is allocated. Thus changed that free the table, not its
1062 * In server's whois_check and identify_check if the client is
1063 locally connected do not send any WHOIS commands - they are not
1066 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1068 * Fixed some minor bugs in client when sending WHOIS command. The
1069 arguments was in wrong order.
1071 * Removed statis function add_to_channel from server in
1072 silcd/command.c that was previously used with the joining but
1075 * Tested USERS command in router environment successfully with two
1076 routers, two servers and two clients.
1078 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1080 * Reorganized the USERS command and command reply in client library
1081 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1082 When the command is given by user we register a pending command
1083 callback that will reprocess the command after the reply has been
1084 received from the server. When reprocessing the packet we then
1085 display the information. Thus, the USERS information is displayed
1086 now in the command callback instead of in the command reply
1087 callback. The processing of the command is same as previously
1088 when server has sent the command reply in the JOINing process.
1090 * Added to USERS command in silcd/command_reply.c to join the client,
1091 we didn't use to know about, to the channel after we've created
1092 a client entry for it. Also, for clienet we did know already still
1093 check whether it is on the channel or not and add it if not.
1095 * Removed silc_server_command_join_notify as the function and its
1098 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1100 * Changed the client's pending command handling to the same as the
1101 server's pending command handling. It is also now possible to
1102 execute command reply functions from other command reply
1103 function as the function callbacks for commands and command
1104 replies are one and same. The pending commands are not static
1105 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1106 in client connection context. Thus, pending commands are server
1107 connection specific as it is convenient.
1109 Changed the function silc_client_command_pending and
1110 silc_client_command_pending_del and added new function
1111 silc_client_command_pending_check. Removed the
1112 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1115 * Added cmd_ident, current command identifier, to the client
1116 connection context in lib/silcclient/client.h to keep track on
1117 command identifiers used in command sending. Client's command reply
1118 function handling now supports the mandatory command identifiers.
1120 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1121 funtions in client to fully support pending command callbacks.
1123 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1124 as one of the arguments to the application in the command reply
1127 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1128 before first releasing SILC but came back. Now it is removed again
1129 and should come back nomore. The FORWARDED flag was used only
1130 by the JOINing procedure by forwarding the command packet to router.
1131 Now, the JOINing procedure has been changed to more generic (due
1132 to various router environment issues) and FORWARDED is not needed
1133 anymore for anything. The protocol specification is yet to be
1136 Now, removed silc_server_packet_forward from server and the flag
1137 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1139 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1141 * Renamed NAMES command to USERS command. The NAMES was named that
1142 due to historical reasons. Now it is renamed. Also, rewrote
1143 parts of the USERS command. The nickname list is not sent anymore
1144 by the server. Only Client ID and mode lists are sent in the USERS
1145 command. Changed this also to the protocol specification.
1147 The client now resolves the names and stuff after it receives
1148 the USERS list from the server when joining to the channel.
1150 * WHOIS and IDENTIFY commands has been changed to support multiple
1151 Client ID's per command. One can now search for multiple users
1152 in the network by sending only one WHOIS or IDENTIFY command.
1153 Changed the code and the protocol specifications.
1155 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1156 uses silc_server_command_whois_parse to parse the request. */
1158 * If normal server, do not parse the WHOIS and IDENTIFY requests
1159 before sending it to the router. Saves some time.
1161 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1163 * Fixed JOIN command on client library. Wrong number of arguments
1164 used to crash the client.
1166 * Added silc_server_channel_has_global function to check whether
1167 channel has global users or not.
1169 * Added silc_server_channel_has_local function to check whether channel
1170 has locally connected clients on the channel.
1172 * The silc_server_remove_from_one_channel now checks whether the
1173 channel has global users or not after given client was removed from
1174 the channel. It also checks whether the channel has local clients
1175 on the channel anymore. If it does not have then the channel entry
1176 is removed as it is not needed anymore.
1178 * The silc_server_notify now checks on JOIN notify whether the joining
1179 client is one of locally connected or global. If it is global then
1180 the channel has now global users on the channel and that is marked
1181 to the channel entry. Also, it now saves the global client to
1182 global list who is joining and JOINs it to the channel. This is
1183 for normal server, that is.
1185 Changed silc_server_send_notify_on_channel,
1186 silc_server_packet_relay_to_channel and
1187 silc_server_packet_send_to_channel check if we are normal server
1188 and client has router set (ie. global client) do not send the
1189 message to that client, as it is already routed to our router.
1191 * Implemented LEAVE notify type handling in silc_server_notify
1194 * Tested LEAVE command in router environment successfully. Tested
1195 with two routers, two servers and two clients.
1199 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1201 * Implemented SIGNOFF notify type handling in silc_server_notify
1204 * silc_server_remove_id now removes the client entry from all channels
1205 it has joined and thusly sends SIGNOFF notify type.
1207 * Rewrote the NAMES list generation in server by removing two excess
1208 loops. The lists are created now inside one loop.
1210 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1212 * silc_server_remove_channel_user checks now also global list
1213 for channel and client.
1215 * silc_server_new_channel_user checks now both local and global
1216 list for channel and client. Fixed a bug in client id decoding.
1217 Used to decode wrong buffer.
1219 * silc_server_channel_message checks now both local and global
1220 list for channel entry.
1222 * Tested channel joining (hence JOIN) in router environment
1223 successfully. Tested with two routers, two servers and two
1226 * Tested channel message sending in router environment successfully.
1228 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1230 * Added silc_server_save_channel_key into server.[ch] to save the
1231 received channel key in Channel Key payload processing. It is
1232 also used in JOIN command reply handling.
1234 Equivalent function silc_client_save_channel_key added into
1235 client.[ch] into client library.
1237 * Changed JOIN command reply to send information whether the channel
1238 was created or not (is existing already) and the channel key
1239 payload. Changed protocol specs accordingly.
1241 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1242 the request was sent by ID and not by nickname. Crashed on
1245 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1247 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1248 now correctly save the received data.
1250 * silc_server_free_sock_user_data now notifies routers in the
1251 network about entities leaving the network.
1253 At the same time implemented functions silc_server_remove_id
1254 and silc_server_send_remove_id to receive and send REMOVE_ID
1255 packets. The packet is used to notify routers in the network
1256 about leaving entities. The ID removed will become invalid in
1259 * Added function silc_idlist_del_server into server. Removes and
1260 free's server entry from ID list.
1262 * silc_server_private_message function now checks, if we are router,
1263 that the destination ID really is valid ID, naturally.
1265 * In router when NEW_ID packet is received (for new client) the
1266 hash of the Client ID is saved in the ID Cache but the
1267 client->nickname is set to NULL, instead of putting the hash
1270 IDENTIFY command now also checks that client->nickname must be
1271 valid. If it is not if will request the data from the server who
1272 owns the client. Added new function
1273 silc_server_command_identify_check.
1275 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1276 to set the command to already allocated Command Payload.
1278 * Tested private message sending in router environment with two
1279 routers, two servers and two clients. Fixed minor bugs and now
1282 * Fixed segfault from client's NAMES command. Used to crash if
1285 * Forwarded packets must not be routed even if it is not destined
1286 to the receiver. Changed server code comply with this.
1288 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1290 * Added `require_reverse_mapping' boolean value to ServerParams
1291 structure. If TRUE (not default) the server will require that
1292 the connecting host has fully qualified domain name.
1294 If the reverse mapping is not required and hostname could not be
1295 found the IP address is used as hostname.
1297 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1299 * Implemented version string checking to both client and server.
1300 The check is incomplete currently due to the abnormal version
1301 strings used in development version of SILC.
1303 * Changed all command functions in server to use the new
1306 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1308 * Changed char *data to unsigned char *data in ID Cache system to
1309 support binary data as ID Cache data. Changed code to support
1310 binary data in lib/silccore/idcache.c.
1312 * Renamed silc_server_packet_relay_command_reply to
1313 silc_server_command_reply as it is normal packet receiving
1314 function. Rewrote the function to accept command replys for
1315 servers and not only for clients.
1317 * Mark remote router always as registered server if we are connecting
1318 to it. Otherwise, commands sent by the router to us are ignored.
1320 * All ID List find routines now returns the ID Cache Entry pointer
1321 as well if requested.
1323 * WHOIS command works now in router environment, tested with two
1324 routers, two servers and two clients.
1326 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1327 in router environment (as it is almost equivalent to WHOIS) but
1328 hasn't been tested thoroughly. Added new functions:
1330 silc_server_command_identify_parse
1331 silc_server_command_identify_send_reply
1332 silc_server_command_identify_from_client
1333 silc_server_command_identify_from_server
1335 * Disabled route cache adding because adding two different ID's with
1336 same IP replaces the old cache entry thus giving wrong route.
1337 The entry->router->connection is always the fastest route anyway
1338 so route cache may not be needed. Of course, new routes maybe
1339 established after receiving the ID when the entry->router->connection
1340 might not be anymore the most optimal.
1342 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1344 * Add route cache for received ID for fast routing.
1346 * Added silc_server_packet_route to route received packet on router
1347 that is not destined to us.
1349 * Renamed silc_server_get_route to silc_server_route_get.
1351 * Added id_string and id_string_len fields into SilcServer to
1352 include encoded ServerID for fast comparing without excess
1353 encoding of the ID's.
1355 * Cleaned up WHOIS command on server side. Added following static
1358 silc_server_command_whois_parse
1359 silc_server_command_whois_check
1360 silc_server_command_whois_send_reply
1361 silc_server_command_whois_from_client
1362 silc_server_command_whois_from_server
1364 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1365 arguments in command replies. All command functions should be
1366 updated to use this macro.
1368 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1370 * Minor typo fixes on command reply handling on server.
1372 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1374 * Added silc_server_command_add_to_channel internal routine to add
1375 the client to the channel after router has created the channel and
1376 sent command reply to the server.
1378 * Added generic silc_server_send_command to send any command from
1381 * Use static buffer with ID rendering instead of duplicating data.
1383 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1385 * Fixed a channel user mode bug when joining to a channel server gave
1386 everybody channel founder rights, oops.
1388 * We mark ourselves as the router of the incoming server connection
1389 if we are router ourselves. This way we can check in some packet
1390 sending functions whether it is locally connected server. For
1391 incoming router connections we put NULL.
1393 * For router sending packets locally means now always sending the
1394 packet cell wide; to local clients and local servers. For normal
1395 server sending packet locally means sending it to only local
1398 * Fixed the JOIN command to really work in router environment. If the
1399 channel is created it is always created by the router. Router is
1400 also responsible of making the initial joining to the channel,
1401 sending JOIN notify to the sending server and distributing
1402 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1403 does not exist server doesn't do anything else but forward the
1404 command to the router which performs everything.
1406 * Added silc_server_send_channel_key function to send the Channel Key
1409 * Added silc_server_create_channel_key to create new channel key. The
1410 channel key is now re-generated everytime someone joins or leaves
1411 a channel, as protocol dictates. Note: channel->key_len is the
1414 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1416 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1417 packet_receive.[ch] to separate packet sending and receiving
1418 routines. The server.[ch] now includes everything else including
1419 actual packet processing (writing and reading data) and other
1422 Renamed silc_server_private_message_send_internal to
1423 silc_server_send_private_message. The routine is still though
1424 used only to relay private messages as server does not send
1425 private messages itself.
1427 Renamed silc_server_new_channel to silc_server_create_new_channel
1428 and added new function sicl_server_new_channel that handles the
1429 incoming New Channel packet. Added also new sending function
1430 silc_server_send_new_channel to send New Channel Payload.
1432 * Added new function silc_server_notify to process incoming notify
1433 packet to the server/router. Server may then relay the notify
1434 to clients if needed.
1436 * Added new function silc_server_new_channel_user to process incoming
1437 New Channel User packet. Router will redistribute the packet and
1438 send JOIN notify to its local clients and locally connected servers
1439 if needed. Normal server will send JOIN notify to its local client
1440 on same channel when received this packet. Added also corresponding
1441 sending function silc_server_send_new_channel_user to sent the
1444 * Added boolean route argument to send_notif_to_channel and
1445 packet_send_to_channel functions to attempt to route the packet
1446 if it is TRUE and send only locally if it is FALSE.
1448 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1450 * silc_server_replace_id now broadcasts the received replace ID
1451 packet if it is not broadcast packet already. The router must
1452 broadcast to inform other routers about changed ID.
1454 * Added backpointer to server's router into SilcServer context in
1455 silcd/server_internal.h.
1457 * Fixed silc_server_packet_broadcast to send correct broadcast
1460 * The channel key is now distributed to the local client as soon
1461 as it is received from the router (in router environment) so that
1462 no other packet may be sent for the channel until client has
1465 * silc_server_remove_channel_user now broadcasts the received
1466 Remove Channel User packet if it is not broadcast packet already.
1467 The router must broadcast to inform other routers about removed
1470 * Added users field into SilcPacketContext that is a reference count
1471 of the context. One can increase the reference count by calling
1472 silc_packet_context_dup which is now changed to just increase the
1473 reference count instead of duplicating the data. The reference
1474 count is decresed by calling silc_packet_context_free that will
1475 free the data after the reference count hits zero.
1477 For now on the packet context and everything allocated into it
1478 (including the raw packet from network) must be freed by calling
1479 the new silc_packet_context_free function. Added also new function
1480 silc_packet_context_alloc that must be used now to allocate the
1481 context. This also means that if a routine is asynchronous from
1482 silc_[client/server]_packet_parse_type the packet context must
1483 be duplicated by calling silc_packet_context_dup. Otherwise it
1484 gets free'd after silc_[client/server]_packet_parse_type returns.
1485 Also, one must remember that if packet is duplicated then its
1486 reference count must be decresed by calling the free function as
1487 many times as it was duplicated.
1489 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1490 from both client and server.
1492 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1494 * Made joining to a channel working in router environment.
1496 * Cleaned up JOIN command on server side and create function
1497 silc_server_command_join_channel internal routine to make the
1500 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1502 * Changed silc_command_pending list to SilcDList. Also, added
1503 `ident' field to SilcServerCommandPending structure to identify
1504 the reply and to call correct callback.
1506 Added silc_server_command_pending_check function to replace the
1507 corresnponding macro. The silc_command_pending list is not
1510 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1511 to set identifier to previously allocated Command Payload. It
1512 is used to set identifier for command when resending Command
1515 * Added silc_command_payload_encode_payload to encode Command
1516 Payload buffer from SilcCommandPayload structure.
1518 * Added silc_argument_payload_encode_payload to encode Argument
1519 payload buffer from SilcArgumentPayload structure.
1521 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1523 * Changed WHOIS command to support router connection on server side.
1524 The whois request is always sent to router unless the server is
1525 standalone server. After server has received the reply from the
1526 router will it send the reply to the client.
1528 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1529 broadcast received broadcast packet. The function is used only
1530 by router. The broadcast packet is always sent to the router's
1533 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1534 render given ID to printable string, for log files for example.
1536 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1538 * Made basic router to router connections working. At least they
1539 can now connect to each other but nothing really works the way
1540 they are supposed - yet.
1542 * Added new initiator token to RouterConnection configuration
1543 file in silcd/serverconfig.[ch]. It is used to tell whether we
1544 are the initiator to the remote router or whether we'll expect
1545 the other end to connect.
1547 * Moved registering of listener task to silc_server_init, hence
1548 the server starts listenning as soon as it is run, even if it
1549 does not have connections to other routers. Let's see how well
1552 * Changed default connection retry timeouts for more suitable in
1555 * Removed cipher and such arguments from silc_idlist_add_client
1556 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1557 Added new function silc_idlist_add_data to add the keys and stuff
1560 * Added SilcIDListData structure and added it to SilcClientEntry
1561 and SilcServerEntry as their first field in the structure. This
1562 way we can explicitly cast the ID entries to the SilcIDListData
1563 structure and get common data for the entries. In past, we had
1564 to first check what type of connection it is and then cast it to
1565 correct ID entry type. Now, we can directly cast the opaque
1566 pointer to the SilcIDListData (no matter what ID entry it actually
1567 is) and get the data needed.
1569 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1571 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1572 in some circumstances even if threre were timeout tasks, though not
1573 IO tasks, but tasks anyway. Now fixed.
1575 * Defined SilcServerConnection structure to hold connection specific
1576 stuff about directly connected servers and routers. The definition
1577 is currently in silcd/server_internal.h. I thought about having
1578 a bit more important role fro this struct but for now it is used
1579 only when connecting to other server (or router actually).
1581 * Added connecting retry support in server when connecting to
1582 router(s). The retry feature implement exponential backoff
1583 algorithm. Also, added SilcServerParams structure to hold default
1584 parameters for server. For now, it include these retry settings
1585 and are hard coded. After server is moded to be as Silc Server
1586 Library this structure will be more important.
1588 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1590 * Changed client librarys channel->clients table to SilcList and
1591 changed code accordingly.
1593 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Changed client's channel table to SilcList and changed code
1596 accordingly. Also changed SilcChannelClientEntry to include back-
1597 pointer to the channel so that client entry can use that structure
1598 as list as well and we have fast cross-reference to the channel.
1599 This change dramatically decreased the complexity of channel
1600 handling with client entry and vice versa (removed one extra
1601 loop when searching for channel entry from many functions).
1603 * Changed server->sim from table to SilcDList and changed code
1606 * NAMES command can now be used from user interface. It will show
1607 the user list on the channel, neatly.
1609 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1610 Code now saves realname of the user if it becomes available.
1612 * Renamed configure.in to configure.in.pre and made ./prepare
1613 script to automatically add correct version string to
1614 configure.in which it creates from configure.in.pre.
1616 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1618 * NAMES command reply now shows users mode with the nickname when
1621 * Moved silc_client_ch[u]mode[_char] functions from
1622 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1623 place sucks, they are utility functions and should be in some
1626 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1628 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1631 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1635 * Added TRQ (efficient deque and list library) into lib/trq. This is
1636 a very good list library that is currently used in the SILC. Defined
1637 SilcList API over the library because I didn't like the API very
1638 much. See lib/trq/silclist.h for the API and examples of how to
1639 use the API. Fixed various places in the code to use the new
1640 SilcList API. The SilcList is meant for lists that has a structure
1641 already defined as a list. It is not suitable to add just some
1642 context to the list (in TRQ, the context is the list actually).
1644 So, I defined SilcDList that can be used for the purpose where
1645 predefined list structure does not exit. This can be used as
1646 such list. Now some context just can be added to the SilcDList.
1647 Currently this list is not used in the SILC just yet, though there
1648 are a lot places where this can replace dynamically allocated
1649 tables and I will fix these places, later, to use SilcDList.
1650 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1651 and use TRQ internally).
1653 Also fixed some annoying warning messages that the original TRQ
1654 code generated. Also minor changes to TRQ's Makefile.in.
1656 * Added support for querying by Client ID to both WHOIS and
1657 IDENTIFY commands into server, as required by the protocol.
1659 * Removed method function pointers from SilcBuffer structure. They
1660 weren't used to anything and just increased the context size for
1661 no good reason. This change also made silc_buffer_alloc and
1662 silc_buffer_free functions inline functions.
1664 * Disabled command flooding detection support until it's fixed so
1665 that it accepts commands in but does not execute them more than once
1668 * Added silc_net_localhost(), to return local hostname, into
1669 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1670 that must be initialized before calling silc_client_init.
1672 * Added new function: silc_server_send_notify_on_channels to send
1673 notify messages to all channels client has joined. It is assured
1674 that the message is sent only once per client.
1676 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1677 lib/silcutil/silcutil.[ch] as silc_format function. The new
1678 function is generic and is used by server as well, not only by
1679 the logging routines.
1681 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1682 the provided version string was not acceptable. Added new function:
1683 silc_ske_check_version into lib/silcske/silcske.h. The function
1684 must be implemented by the application (client or server) and it
1685 does not reside in the SKE library. The function checks the version
1686 string remote end sent.
1688 * Added back pointers (to opaque context and to SilcSocketConnection)
1689 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1691 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1692 duplicate packet context structure.
1694 * Changed `notify' client operation to send same arguments as client
1695 receives from server except for ID's. ID's are mapped to correct
1696 ID entry and that is returned. Also, if channel entry is not sent
1697 by server but the notify is for channel the channel entry is sent
1698 to application (otherwise application doesn't know that it is for
1699 channel (library gets it from packet's Destination ID)).
1701 * Added silc_client_remove_from_channels into client library to
1702 remove a client from all channels it has joined to. Used when
1703 received SIGNOFF notify from server. Added also new function
1704 silc_client_replace_from_channels to replace old ID entry with
1705 new ID entry on all channels. Used when received NICK_CHANGE
1708 * Fixed ID Cache list handling in silc_idlist_get_client in
1709 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1710 to get (or query) client by ID.
1712 * Updated TODO list.
1714 * Added connection authentication status message defined by the
1715 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1716 support for these into the code in client and server side.
1718 * Added generic function silc_client_send_command to send any command
1719 with variable argument list. Application should use this function
1720 to send commands if the command functions provided by the library
1721 does not suite for the application's user interface needs.
1723 * Added new `failure' client operation. Application is notified about
1724 received failure packet if client is executing a protocol. In this
1725 case the protocol's execution has failed.
1727 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1728 is required by the protocol.
1730 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1731 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1734 * Added status flag to SilcSKE object to indicate realtime status
1735 of the SKE protocol.
1737 * Application receives now exactly same command reply arguments as
1738 the library receives from server. However, if ID is received the
1739 corresponding ID entry is returned to the application (eg. Client
1740 ID is mapped to correct SilcClientEntry entry and that is returned).
1741 Changed command_reply client operation due to this change.
1743 * Changed all ID's in commands and in command replys as ID Payloads.
1744 Change affected both client and server side codes.
1746 All ID's sent in SILC network (with execption of ID's in SILC
1747 Packet header) are sent in ID Payload to support variable length
1750 * Server now notifies nick changes and notifies all clients on
1751 the channels about the new nickname (about the new Client ID,
1754 * Implemented CMODE command to change channel modes. Supports all
1755 channel modes defined by the protocol specs except ban and invite
1756 lists. (Also, private channel key mode is supported but support for
1757 setting private channel key in client is missing, thus, this mode
1758 has no effect on client side (except that server requires that the
1759 client uses private channel key and normal channel traffic does not
1762 Also, invite mode works per se, but INVITE command does not work
1763 yet correctly, so you can set channel as invite only channel but
1764 inviting clients to the channel does not work (it is yet to be
1765 thought what's the best way to do it).
1767 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1768 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1769 Implemented CUMODE command to change user's mode on the channel.
1770 Supports all modes defined by the protocol specs.
1772 * Added NAMES command reply to return users modes on the channel.
1774 * Removed unnecessary and slow ciphers from lib/silccrypt.
1776 * Set SO_KEEPALIVE option to connection sockets by default.
1778 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1780 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1781 redefined the Notify Payload into protocol specs.
1783 * Added silc_id_payload_parse_id to get ID directly from raw
1786 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1788 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1789 accept searching by Client ID as well.
1791 * Added support for LEAVE and SIGNOFF notify types in client library.
1793 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1794 to parse ID Payload from raw data.
1796 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1798 * Added flags parameter into silc_ske_assemble_security_properties
1799 function in lib/silcske/silcske.[ch].
1801 * Changed notify client operation to fit better for notify messages
1802 sent by server. The notify payload received from server is now
1803 passed to the application (after parsing it to SilcNotifyPayload).
1804 It is application's responsibility to retrieve the arguments
1805 from the payload and show the message the way it wants. The message
1806 sent by server is implementation specific.
1808 * Changed public keys to comply with the protocol specification.
1809 Old public keys are not supported anymore and are not compatible.
1811 * Removed nickname from Channel Payload as the latest draft removed
1812 it. The client must resolve the nickname from the NAMES command
1813 reply received when it joined the channel.
1815 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1817 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1819 * Fixed some errors in protocol specification drafts.
1821 * Created lib/silccore/silcnotify.c to implement Notify Payload
1822 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1823 generic payloads described by protocol specifications. The file
1824 includes implementations for ID Payload and Argument Payload.
1826 * Changed Command Payload implementation to use the new Argument
1827 Payload. Changed command_xxxx_payload to command_payload_xxxx
1828 to comply with SILC coding conventions.
1830 * Added suppport for Argument Payload handling in Notify Payload
1831 implementation as protocol requires it. Added the new support
1832 into server and client lib as well.
1834 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1836 * Added support for multiple nicknames on same channel. [n] is
1837 added locally to the nickname if there are more than one same
1838 nicknames on the channel.
1840 * Server now sends all nicknames that matched WHOIS request.
1841 Client also shows the list received from server.
1843 * Added TOPIC command to client side. User can now set and show
1844 current topic on channel.
1846 * Added MOTD command to client and server. Also, server sends the
1847 motd when client connects to the server.
1849 * Changed version strings to comply ISO 8601.
1851 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1853 * Fixed protocol error handling in client library. It should now
1854 cope even if the SKE fails for some reason.
1856 * Made new protocol specification drafts for submitting to IETF.
1858 * Implemented TOPIC command to server in silcd/command.c.
1860 * Added two new notify types into lib/silccore/silcnotify.h:
1861 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1862 notify nickname change and topic setting/change on a channel.
1864 * API change of command_reply operation in client library. The
1865 application gets now the status type received from server as well.
1867 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1869 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1871 * Cras fixed and optimized the packet handling even further and
1872 it should work now. Minor change to the prototype of function
1873 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1875 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1877 * Added new function into lib/silcutil/silcschedule.[ch]:
1878 silc_schedule_with_fd to select() a specified fd. The function
1879 returns after timeout expires or data arrives or goes. The
1880 function is used by packet routines to wait that all data is
1881 received from network.
1883 * Fixed data reading from network in lib/silccore/silcpacket.c.
1884 The code now assures that all data is read from the fd and then
1885 continues packet processing. This was a bug fix since the code
1886 used to drop some data in some circumstances.
1888 * Added new function into lib/silcclient/client.[ch]:
1889 silc_client_start_key_exchange to start key exchange after
1890 connection has been established to server. The code internally
1891 now uses this funtion but its main purpose was to provide it
1892 for applications that perform their own connecting. After
1893 application has created a connection it merely calls this
1894 function to start the key exchange between client and server.
1895 The library takes care of everything else after that.
1897 Updated also lib/silcclient/README to explain the usage of
1900 * Do not send to application information that connection has
1901 been established. Application gets notified it by connect
1904 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1906 * Applied cras's patch to add silc_schedule_one function. The
1907 function runs scheduler once and returns.
1909 * Fixed the scheduler after cras messed it up. The timeout
1910 handling works now as it's supposed to work.
1912 * Added into lib/silccore/ silcnotify.h to include notify
1913 message types support. Changed silc_server_send_notify*
1914 functions, in server.[ch], to support those new notify types.
1915 Added the support for the notify types into client library,
1916 as well. Added new notify client operation into ops.h in
1919 * Changed silc_server_packet_send_to_channel to send normal
1920 packets instead of just channel message packets. The function
1921 is now used to send the notify packets to channels. It is not
1922 used to send channel message packets anymore, as server never
1925 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1926 va_arg()s as it seems to require it nowadays. I guess, if SILC
1927 is compiled with older va_arg() the new code should work anyway.
1929 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1931 * Splitted core library. Core library (lib/silccore) includes
1932 now only SILC protocol specific core (and common) components.
1933 Created new utility library (lib/silcutil) that includes more
1934 generic purpose stuff. The stuff for util library was taken
1935 from the old core library. This was minor and easy split.
1937 * Created SILC Client Library (lib/silcclient) that includes
1938 implementation of the SILC client without user interface. This
1939 was major move from silc/ directory. The code has been changed
1940 so that it is transparent towards the user interface. The
1941 silc/ directory includes now the same user interface as before
1942 and it uses the new client library. Read lib/silcclient/README.
1943 Basicly, the client library performs everything else related
1944 to SILC except user interface handling. Also, configuration
1945 files are considered to be part of user interface and library
1946 does not handle them.
1948 This change also changed a lot of structures, function naming etc.
1949 Most important change was that SilcClientWindow object was
1950 renamed to SilcClientConnection in the client library. Created
1951 also new file lib/silcclient/ops.h. Also added new files
1952 silc/local_command.[ch] and silc/client_ops.[ch].
1954 All these changes were made to make it easier for user interface
1955 designers to create what ever user interface for the SILC client
1958 It is also expected that the server will be moved to lib
1959 directory as well and SILC Server Library will be created;
1960 sometimes in the future.
1962 * Removed Local commands from lib/silccore/silccommand.h as
1963 they are application specific and new client library does not
1964 handle any of those anymore.
1966 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1967 old client implementation in silc/.
1969 * Added support for callback functions in SILC_LOG_* macros.
1970 Application can now set its own callbacks that will be called
1971 instead of using the default functions that will always print
1972 the debug messages to stderr (or stdout). Also, debugging can
1973 now be disabled by setting silc_debug to FALSE and re-enabled by
1974 setting it to TRUE. Note, that logging will still work even
1975 if debugging is disabled.
1977 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1978 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1979 silc_log_reset_debug_callbacks.
1981 * To enable debugging in silc client one must give now -d
1982 option on command line.
1984 * Changed silc_schedule_init to automatically allocate task queues
1985 if they are not allocated before calling it.
1987 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1989 * Added GMP 3.1 into math library.
1991 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1993 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1994 a channel in SILC network. The packet is used by servers and
1995 routers to notify other routers that user has left a channel.
1996 This little feature was missing until now. Added the feature
1997 to protocol specification as well.
1999 Added functions: silc_server_send_remove_channel_user and
2000 silc_server_remove_channel_user into server.[ch].
2002 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2003 lib/silccore/silcpacket.h. However, they are not implemented
2006 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2008 * Fixed joining to a channel and sending channel messages
2009 between server and router. The channel message sending should
2010 now work inside a cell.
2012 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2014 * Fixed the private message sending between server and router.
2015 The private message sending should now work inside a cell.
2017 * Added silc_server_replace_id into server.[ch] to replace
2018 existing ID in the SILC network.
2020 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2021 and silc_idlist_replace_server_id into idlist.[ch] in server.
2023 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2025 * Fixed the server to server connections. Server can again now
2026 connect to router. Router to router connections probably does
2029 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2031 * Added dynamic protocol registering support. Now protocols can
2032 registered and unregistered on the fly. Patch by cras.
2034 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2036 * Added lib/contrib directory to hold routines that some platforms
2037 don't have but are needed by SILC.
2039 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2040 into lin/contrib to provide getopt() and getopt_long() for
2041 those who don't have it.
2043 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2045 * Added AWAY command to client. When away message is set and
2046 client receives a private message packet the client automatically
2047 replies to the sender with the away message.
2049 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2050 bug seemed to be the cause of recent problems when compiling
2053 * Added version detection support to SKE protocol specification
2054 and added the new changes to the SKE implementation as well.
2055 There were other minor changes in the SKE protocol as well.
2057 Many changes in lib/silcske/silcske.[ch] and in
2058 lib/silcske/payload.[ch].
2060 * Added ^U functionality, clear input line. Patch from cras.
2062 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2064 * Mainly small bugfixes on core library. Fixed some debugging
2065 logging and buffer overflow in silclog.c.
2067 * Updated config.sub and config.guess on the distribution tree.
2069 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2071 * Added command lagging support in server. Client may execute
2072 commands now only once in two seconds.
2074 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2076 * Optimized packet reception. MAC computation and checking is now
2077 also more optimized. A lot previously duplicated code is now
2078 used as generic by both client and server.
2080 * Fixed key pair generation in clientutil.c
2082 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2084 * Added into lib/silccore/silcbufutil.[ch] new function;
2085 silc_buffer_realloc.
2087 * Moved generic packet sending/encryption functions to
2088 lib/silccore/silcpacket.[ch] from client and server. Some
2089 rewriting of the functions.
2091 * Moved all generic packet reception/decryption functions to
2092 lib/silccore/silcpacket.[ch] from client and server. The
2093 packet processing is now much cleaner in both client and server.
2094 These were major changes in both client and server.
2096 * Created many common functions in server to do packet sending.
2097 Previously code were duplicated a lot, this has been removed
2100 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2102 * Rewrote major parts of the ID cache system. Don't know
2103 whether it is better now or not but at least the API is more
2106 * Major rewrite on ID cache stuff on client because of the ID
2107 cache API changes. Added idlist.c to client.
2109 * Also major rewrite on ID cache stuff on server as well.
2110 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2111 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2112 in hand, instead they are all put into the ID cache system now.
2113 All server_idlist_* routines uses ID cache now instead of
2114 traversing its own lists (those lists does not exist anymore).
2115 SilcIDList though still exists. Also, SilcXXXEntry's are
2118 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2120 * Finally made the SKE implementation compliant to the protocol
2121 specification. All mp integers are now binary encoded as
2122 opposed being HEX encoded.
2124 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2127 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2128 functions: silc_[encode/decode]_pem. Also added function
2129 silc_encode_pem_file to PEM encode with newlines ('\n') for
2132 * SILC public keys are now encoded either PEM or binary. Same
2133 option is for private keys as well. By default private keys
2134 are binary encoded and public keys PEM encoded. Silly HEX
2135 encoding were removed.
2137 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2138 function to create fingerprints.
2140 * Fixed a bug in SHA1; does not change the original data anymore.
2142 * Partly implemented INFO command on client and server side.
2143 Fixed CLEAR command. Changes to SERVER command; show current
2144 server(s) when giving command without arguments. Added
2145 VERSION command to client.
2147 * Added check to server that unregistered connections cannot
2148 execute commands (unless it is specificly allowed).
2150 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2152 * Fixed screen refresh.
2154 * Fixed channel joining bug from client. On some circumstances
2155 client tried to join to a channel it had already joined.
2157 * Added public key verification process into client's protocol.c.
2158 The client now verifies the public key from user and saves
2159 it into ~./silc/serverkeys/ directory.
2161 Added into: clientutil.[ch]: silc_client_verify_server_key.
2163 * Changed SKE protocol's silc_ske_initiator_finish function
2164 to accept callback function that verifies the received public
2165 key. Removed old silc_ske_verify_public_key function.
2167 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2169 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2170 silc_pkcs_private_key[_data]_set.
2172 * Made the password and public authentication more cleaner in
2173 server's protocol.c.
2175 * Removed historic and obsolete protocol `channel_auth' from
2176 both client and server.
2178 * Removed wrong way of sending command status messages from
2179 server to client in server's command.c. The old way violated
2180 protocol specification.
2182 Changes to silccore/silccommand.[ch]: removed
2183 silc_command_encode_status_payload -> not needed anymore,
2184 changed silc_command_encode_payload_va to accept extra
2185 argument on variable argument list. The argument type must
2186 now be provided to the function. Also, added new function:
2187 silc_command_encode_reply_payload_va which is same as
2188 normal command_encode_payload_va except command status type
2189 is provided as extra argument.
2191 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2193 * Added ~./silc directory handling. The directory includes the
2194 public and private keys for the client.
2196 Added silc_client_check_silc_dir, silc_client_create_identifier
2197 and silc_client_load_keys.
2199 * Implemented SILC protocol compliant public key. Added public
2200 and private key saving to and loading from files.
2202 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2203 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2204 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2205 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2206 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2208 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2209 silc_pkcs_load_[public/private]_key.
2211 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2213 * Added silc_server_get_route (route.[ch]) to get connection
2214 data for the fastest route for given ID.
2216 * Implemented INVITE command on client and server. The command
2217 were re-defined in the SILC Protocol Specification and the
2218 implementation now complies with the specification.
2220 * Implemented PING command on client and server.
2222 * Implemented NAMES command on client and server. The server side
2223 supports currently only normal server not router server yet.
2224 Some changes to NAMES definition in SILC protocol specification.
2226 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2228 * Implemented LEAVE command on client and server.
2230 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2231 again. This change was made to the protocol as well. Server
2232 should not violate the protocol specification anymore.
2234 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2236 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2237 was tested. SOCKS4 was not but should work anyway.
