1 Tue Mar 13 12:49:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
3 * Added dist-bzip hook to the Makefile.am to make bzip2
4 compressed distributions.
6 Mon Mar 12 18:43:38 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
8 * Server now enforces the maximum length for the nickname and
9 the channel as protocol specification dictates. 128 bytes for
10 nickname and 256 bytes for channel name.
12 * Moved the WHOIS printing to the application. The client libary
13 does not print out the WHOIS information anymore, the application
14 must do it. Renamed silc_client_command_reply_whois_print to
15 the silc_client_command_reply_whois_save.
17 The client's idle time is also sent to the application now, and
18 the idle is shown on screen.
20 * Added silc_client_command_reply_identify_save to save the
21 received IDENTIFY entries.
23 * Do not check for channel private keys in message sending and
24 reception if the channel does not have the PRIVKEY mode set.
25 Affected file lib/silclient/client_channel.c.
27 Sun Mar 11 20:25:06 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
29 * Fixed a minor bug if WHOIS and IDENTIFY command parsing that
30 just surfaced after chaning the JOIN procedure.
32 Sun Mar 11 14:59:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
34 * Added silc_client_get_clients_by_list to get client entries
35 from Client ID list, that is returned for example by JOIN
36 and USERS command replies. The application should use this
37 function for example when JOIN command reply is received to
38 resolve the clients already on the channel (library does not
39 do that anymore as USERS command reply is not used in the JOIN
40 procedure anymore). Affected files lib/silcclient/silcapi.h and
41 lib/silcclient/idlist.c.
43 * JOIN command reply and USERS command reply returns now SilcBuffer
44 pointers instead of unsigned char pointers when returning
45 the client list and mode list.
47 * Added <Client ID> argument to the JOIN command reply, mainly
48 for the server to identify for which client the command was
49 originally sent. Updated protocol specs accordingly.
51 * Added SilcDlist private_key pointer to the SilcChannelEntry
52 in the client to support the channel private keys. Affected
53 file is lib/silcclient/idlist.h.
55 * Added SilcChannelPrivateKey argument to the function
56 silc_client_send_channel_message so that application can choose
57 to use specific private ke if it wants to. If it is not provided,
58 the normal channel key is used, unless private keys are set.
59 In this case the first (key that was added first) is used
60 as the encryption key.
62 * Implemented the support for channel private key handling.
63 Implemented the following functions:
65 silc_client_add_channel_private_key,
66 silc_client_del_channel_private_keys,
67 silc_client_del_channel_private_key,
68 silc_client_list_channel_private_keys and
69 silc_client_free_channel_private_keys
71 Affected file lib/silcclient/client_channel.c.
73 * Added the support for the private keys in the channel message
74 sending and encryption and in the message reception and
75 decryption. Affected funtions are
76 silc_client_send_channel_message and silc_client_channel_message.
78 Sat Mar 10 21:36:22 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
80 * Added SKE's key verify callback to the client library's
81 KE protocol context. Affected files lib/silcclient/protocol.[ch].
83 * Removed the statement that server (or router) must send USERS
84 command reply when joining to the channel so that the client
85 knows who are on the channel. Instead, the client list and
86 client's mode list is now sent in the JOIN command reply to the
87 client who joined channel. This is better solution.
89 * Added function silc_server_get_users_on_channel and function
90 silc_server_save_users_on_channel to the silcd/server.[ch].
92 * Removed function silc_server_command_send_users from the
95 * Do not show topic on the client library anymore. The topic is
96 sent in the command reply notify to the application and the
97 application must show the topic now.
99 Sat Mar 10 00:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
101 * Added client searching by nickname hash into the IDENTIFY and
102 WHOIS commands in the server as they were clearly missing from
103 them. Affected file is silcd/command.c.
105 * Fixed a bug in private message receiving in the client library.
106 The remote ID was freed and it wasn't supposed, now it is
109 Fri Mar 9 12:40:42 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
111 * Minor fix to the channel payload; allocate the data area, as it
112 needs to be of specific length.
114 * If the key agreement port is zero then the operating
115 system will define the bound port. Affected files are
116 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
118 * Added new function silc_channel_payload_decrypt into the file
119 lib/silccore/silcchannel.[ch].
121 * Moved the channel message etc, check from silc_packet_decrypt
122 to applications. The library calls now a generic
123 SilcPacketCheckDecrypt callback which is to return TRUE or FALSE
124 when the packet is either normal or special. This was done to
125 allow more wide range of checking that was not allowed when
126 the code was in library. Now applications can do virtually any
127 checks to the packet and return to the library the decision how
128 the packet should be processed. Affected files are
129 lib/silccore/silcpacket.[ch].
131 Added silc_server_packet_decrypt_check to the server and
132 silc_client_packet_decrypt_check to the client library.
134 * Added silc_server_packet_send_srcdest into silcd/packet_send.[ch]
135 to send with specified source and destination information.
137 * Channel message delivery between routers was broken after the
138 channel key distribution was fixed earlier. The channel key
139 was used be to distributed to other routers as well which is not
140 allowed by the protocol. Now this is fixed and channel keys
141 really are cell specific and the channel message delivery between
142 routers comply with the protocol specification.
144 * Fixed various commands in server to check also the global list
145 for the channel entry and not just the local list. The affected
146 file silcd/command.c.
148 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
150 * Added assert()s to buffer formatting and unformatting routines
151 to assert (if --enable-debug) when error occurs. Affected
152 file: lib/silcutil/silcbuffmt.c.
154 * Changed to auto-reconnect to check whether the remote host is
155 router and register the re-connect timeout if it is. It used
156 to check that whether we are normal server, but router must do
157 auto-reconnect with another router as well. Affected file
160 * Removed the [<key len>] option from CMODE command as the cipher
161 name decides the key length, nowadays. See the defined ciphers
162 from the protocol specification.
164 * Added [<hmac>] option to the CMODE command to define the HMAC
165 for the channel. Added SILC_CMODE_HMAC channel mode.
167 * Added [<hmac>] option for the JOIN command so that user can
168 select which HMAC is used to compute the MACs of the channel
171 * Added Hmac field to the Channel Message Payload. The integrity
172 of plaintext channel messages are now protected by computing
173 MAC of the message and attaching the MAC to the payload. The
174 MAC is encrypted. Now, it is clear that this causes some
175 overhead to the size of the packet but rationale for this is that
176 now the receiver can verify whether the channel message decrypted
177 correctly and also when private keys are set for the channel the
178 receiver can decrypt the packet with several keys and check from
179 the MAC which key decrypted the message correctly.
181 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
182 lib/silccrypt/silccipher.[ch].
184 * Added silc_hash_len to return the digest length into the
185 lib/silcrypt/silchash.[ch].
187 * Rewrote parts of Silc Channel Payload interface in the
188 lib/silccore/silcchannel.[ch]. The encode function now also
189 encrypts the packet and parse function decrypts it.
191 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Fixed a minor formatting bug in the SKE's key material processing.
194 It actually might have processed the keys wrong way resulting
197 * Redefined the mandatory HMAC algorithms and added new algorithms.
198 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
199 and hmac-md5 truncated to 96 bits. The mandatory is now
200 hmac-sha1-96. Rest are optional (including the one that used
201 to be mandatory). Rationale for this is that the truncated HMAC
202 length is sufficient from security point of view and can actually
203 make the attack against the HMAC harder. Also, the truncated
204 HMAC causes less overhead to the packets. See the RFC2104 for
207 * Added new [hmac] configuration section. The SKE used to use
208 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
209 is of course wrong. The official names that must be proposed in
210 the SKE are the ones defined in the protocol specification
211 (hmac-sha1-96 for example). The user can configure any hmac
212 using any hash function configured in the [hash] section. At
213 least, the mandatory must be configured.
215 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
217 * Added HMAC list to the SKE proposal list. It has now both
218 hash algorithm list and HMAC list. This makes the protocol
219 incompatible with previous versions. The SKE now seems to work
220 the way it is supposed to work, for the first time actually.
222 * Defined plain Hash algorithms to the protocol specification.
225 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
227 * Implemented support for key agreement packets into the server.
228 Added functions silc_server_key_agreement and
229 silc_server_send_key_agreement. Other than these functions,
230 server has nothing to do with this packet.
232 * Added support for private message key packets into the server.
233 Added functions silc_server_private_message_key and
234 silc_server_send_private_message_key.
238 * Changed the silc_[client|server]_protocol_ke_set_keys to be
239 called in the protocol's final callback instead in the END
240 protocol state. This makes a little more sense and in the same
241 time in client we can use the same protocol routines for normal
242 key exchange and to key agreement packet handling as well.
244 * Added to both client's and server's KE protocol context the
245 SilcSKEKeyMaterial pointer to save the key material. We will
246 bring the key material to the protocol's final callback by doing
247 this. The final callback must free the key material.
249 * Added SKE's packet_send callback into client's KE protocol
250 context so that the caller can choose what packet sending function
251 is used. This way we can use different packet sending when
252 doing normal SKE when doing key agreement packet handling (in
253 the key agreement packet handling we do not want to encrypt
256 * Implemented the responder side of the key agreement routines
257 in the client. The client can now bind to specified port and
258 accept incoming key negotiation. The key material is passed
259 to the application after the protocol is over.
261 * Implemented the processing of incoming Key Agreement packet
262 in the client. Added function silc_client_key_agreement to
265 * Implemented the intiator side of the key agreement routines
266 in the client. The client can now initiate key agreement with
267 another remote client. The key material is passed to the
268 application after the protocol is over.
270 * Created client_keyagr.c to include all the key agreement
273 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
274 SILC_TASK_CALLBACK except that it is not static.
276 * Created client_notify.c and moved the Notify packet handling
277 from the client.[ch] into that file.
279 * Created client_prvmsg.c and moved all private message and
280 private message key routines from the client.[ch] into that file.
282 * Create client_channel.c and moved all channel message and
283 channel private key routines from the client.[ch] into that file.
285 * Changed silc_client_get_client_by_id_resolve to resolve with
286 WHOIS command instead of IDENTIFY command, in the file
287 lib/silclient/idlist.c.
289 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
291 * Implemented the SKE's responder side to the Client library.
293 * When FAILURE is received to the protocol do not trust it
294 blindly. Register a timeout to wait whether the remote closes
295 the connection as it should do it, only after that process the
296 actual failure. This was changed to both client and server.
298 * Added client_internal.h to include some of the structures
299 there instead of client.h in lib/silcclient/.
301 * Added function silc_task_unregister_by_callback to unregister
302 timeouts by the callback function.
304 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
306 * Some "Incomplete WHOIS info" errors has been appearing on the
307 log files. Took away the entry->userinfo check from WHOIS
308 reply sending. The entry->userinfo is now " " if client did not
309 provide one. I thought this was fixed earlier but something
310 is wrong still. Let's see if the error still appears.
312 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
314 * Fixed a minor bug in the login when the channel key is
315 re-generated in the server. It used to generate the key in
316 wrong order and thus caused problems in the channel traffic.
318 * Fixed a minor bug in channel key distsribution after
319 KICK command. The key was not sent to the router even though
322 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
324 * Added silc_ske_process_key_material_data as generic routine
325 to process any key material as the SILC protocol dictates. The
326 function is used by the actual SKE library but can be used by
327 applications as well. This relates to the private message keys
328 and the channel private keys since they must be processed the
329 same way the normal SILC session keys. The protocol dictates
330 this. Affected files: lib/silcske/silcske.[ch].
332 Added also silc_ske_free_key_material to free the
333 SilcSKEKeyMaterial structure.
335 * Defined silc_cipher_set_key function to set the key for
336 cipher without using the object's method function. The affected
337 files: lib/silccrypt/silccipher.[ch].
339 * Implemented silc silc_client_add_private_message_key,
340 silc_client_add_private_message_key_ske,
341 silc_client_del_private_message_key,
342 silc_client_list_private_message_keys and
343 silc_client_free_private_message_keys functions in the
346 Added functions silc_client_send_private_message_key to send
347 the Private Message Key payload and silc_client_private_message_key
348 to handle incoming Private Message Key payload.
350 * Added Cipher field to the Private Message Key payload to set
351 the cipher to be used. If ignored, the default cipher defined
352 in the SILC protocol (aes-256-cbc) is used.
354 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
356 * Removed lib/silcclient/ops.h file.
358 Redefined parts of the SILC Client Library API. Created new
359 file silcapi.h that deprecates the ops.h file and defines the
360 published Client Library API. Defined also private message key
361 API and channel private key API into the file.
363 This is the file that the application must include from the
364 SILC Client Library. Other files need not be included by
365 the application anymore.
367 * Added new key_agreement client operation callback and also
368 defined the Key Agreement library API for the application.
370 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
372 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
373 is used by clients to request key negotiation between another
374 client in the SILC network. If the negotiation is started it
375 is performed using the SKE protocol. The result of the
376 negotiation, the secret key material, can be used for example
377 as private message key.
379 Implemented the Key Agreement payload into the files
380 lib/silccore/silauth.[ch].
382 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
384 * Redefined ciphers for the SILC protocol. Added some new ciphers
385 and defined the key lengths for the algorithms. Changed the
386 code accordingly. The default key length is now 256 bits.
388 * Fixed SKE key distribution function silc_ske_process_key_material
389 when the key length is more than 128 bits. The default key
390 length in SILC is now 256 bits.
392 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
393 to indicate unsupported algorithm.
395 * Renamed rijndael.c to aes.c and all functions as well.
397 * Fixed a long standing channel key setting bug in client library.
398 Weird that it has never surfaced before.
400 * Fixed bug in channel deletion. If the entire channel is removed
401 then it must also delete the references of the channel entry
402 from the client's channel list as the client's channel entry and
403 the channel's client entry share same memory.
405 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
407 * Implemented CONNECT and SHUTDOWN commands in the client.
409 * Implemented CLOSE command to the client.
411 * Added the function silc_idlist_find_server_by_name into the
412 files silcd/idlist.[ch].
414 Added the function silc_idlist_find_server_by_conn into the
415 files silcd/idlist.[ch].
417 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
419 * DIE command was renamed to SHUTDOWN. Updated the both code
422 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
423 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
425 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
428 * Added function silc_server_create_connection function to create
429 connection to remote router. My server implementation actually
430 does not allow router to connect to normal server (it expects
431 that normal server always initiates the connection to the router)
432 so the CONNECT command is only good for connecting to another
435 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
437 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
438 or some other client was kicked from the channel.
440 Implemented the handling of the notify type to both client
443 Implemented silc_server_send_notify_kicked to send the KICKED
444 notify. It is used to send it to the server's primary router.
446 * Implemented the KICK command into server and client.
448 * Added `query' argument to the silc_idlist_get_client function
449 to indicate whether to query the client from server or not if
452 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
453 to indicate that the client is not channel founder.
457 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
459 * Removed the rng context from SilcPacketContext structure and
460 changed that the packet routine uses the Global RNG API.
462 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
464 * Added support for quit message that client can "leave" on the
465 channel when it quits the SILC. It is ditributed inside the
466 SILC_NOTIFY_TYPE_SIGNOFF notify type.
468 Added silc_server_free_client_data that will take the
469 signoff message as argument.
471 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
473 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
475 * Updated parts of the protocol specification to keep it up
478 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
480 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
481 payloads in one packet.
483 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
484 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
485 use now the new List flag.
487 * Also deprecated the following packet types: REPLACE_ID,
488 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
490 * Added list support for Notify packet in server.
492 * Added silc_server_send_notify_channel_change to send the
493 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
494 the silc_server_send_replace_id.
496 * Added silc_server_send_notify_nick_change to send the
497 NICK_CHANGE notify type. Deprecates the function
498 silc_server_send_replace_id.
500 * Added silc_server_send_notify_join to send the JOIN notify type.
501 Deprecates the function silc_server_send_new_channel_user.
503 * Added silc_server_send_notify_leave to send LEAVE notify type.
504 Deprecates the function silc_server_send_remove_channel_user.
506 * Added silc_server_send_notify_cmode and
507 silc_server_send_notify_cumode to send CMODE and CUMODE notify
508 types. Deprecates the silc_server_send_set_mode function.
510 * Added SERVER_SIGNOFF notify type to indicate that server has
511 quit. This means that all clients on the channel from that
512 server will drop. This can be also used when netsplit happens.
514 Deprecated REMOVE_ID packet type since it is not needed anymore
517 Added silc_server_send_notify_server_signoff to send the
518 SERVER_SIGNOFF notify type. Deprecates the function
519 silc_server_send_remove_id.
521 Added also silc_server_send_notify_signoff to send the
524 * Employed the PKCS #1. It is the mandatory way to do RSA in the
525 SILC protocol from this day on. Changed the protocol
526 specification as well.
528 * Added silc_server_send_notify_topic_set to send TOPIC_SET
529 notify type. It is used between routers to notify about
530 topic changes on a channel.
532 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
535 * Partly updated the protocol specification to comply with the
536 changes now made. It is still though a bit outdated.
538 * The JOIN notify type now takes one extra argument <Channel ID>.
539 The packet used to be destined to the channel but now the
540 JOIN type may be sent as list thus it is impossible to
541 destine it to any specific channel. By adding this argument
542 it is again possible.
544 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
546 * Added CREDITS file. The CHANGES and CREDITS file will appear
547 in the distribution as well.
549 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
551 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
552 types in the server's silcd/packet_receive.c.
554 * Implemented CMODE and CUMODE to work in router environment.
556 * Fixed minor encoding and decoding buglet from the
557 lib/silccore/silcmode.c.
559 * Fixed buffer overflow from lib/silcclient/command.c in USERS
562 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
564 * Changed all SilcConfigServer* and silc_config_server* to
565 SilcServerConfig* and silc_server_config*, respectively.
568 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
570 * Associated the ID (client or server ID) to the Authentication
571 Payload to avoid any possibility of forging. Updated the
572 protocol specification and the code accordingly.
574 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
576 * The RSA key length is now save to the RsaKey context in the
577 key generation process in lib/silccrypt/rsa.c. The key length
578 is now used to figure out the maximum size of the block allowed
579 to be encrypted/signed.
581 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
582 is equivalent to the silc_mp_mp2bin but does not allocate any
585 * Changed silc_mp_mp2bin API to take length argument. If it is
586 non-zero then the buffer is allocated that large. If zero, then
587 the size is approximated using silc_mp_sizeinbase, which however
590 * Created Global RNG API which is global RNG that application can
591 initialize. After initializing, any routine anywhere in the
592 code (including library) can use RNG without allocating a new
593 RNG object. This was done to allow this sort of use of the
594 RNG in code that has no chance to allocate RNG object. All
595 applications currently allocate this and many routines in the
596 library use this. Affected file lib/silccrypt/silcrng.[ch].
598 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
599 it to use the Global RNG API.
601 * Defined Authentication Payload into protocol specification that
602 is used during SILC session to authenticate entities. It is
603 used for example by client to authenticate itself to the server
604 to obtain server operator privileges.
606 Implemented this payload into the lib/silccore/silcauth.[ch].
607 Implemented also routines for public key based authentication
608 as the new protocol specification dictates.
610 Moved definitions of different authentication methods from
611 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
613 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
614 silc_pkcs_verify and silc_pkcs_sign_with_hash and
615 silc_pkcs_verify_with_hash functions into the file
616 lib/silccrypt/silcpkcs.[ch].
618 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
620 * The client entry's userinfo pointer must be always valid.
621 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
622 will fail since it requires the userinfo. Now, the userinfo
623 is allocated as "" if actual userinfo does not exist. Actually,
624 it must exist and it is totally Ok to drop client connections
625 that does not announce the userinfo. However, we will make
626 this workaround for now.
628 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
629 to return the remote port by socket.
631 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
633 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
634 SILC_SERVER_PENDING_EXEC and added an new macro
635 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
636 data or when error occurs while processing the pending command.
638 Added new argument `destructor' into silc_server_command_pending
639 and to the SilcServerCommandPending object. This destructor is
640 now called after calling the pending callback or if error occurs
641 immediately. If error occurs the actual pending callback won't
642 be called at all - only the destructor. The destructor may be
643 NULL if destructor is not needed.
645 All this applies for client library code as well. Similar
646 changes were made there as well for the pending commands.
648 In the client, the application must now allocate the
649 SilcClientCommandContext with the silc_client_command_alloc
652 * Added reference counter to the SilcServerCommandContext. Added
653 function silc_server_command_alloc and silc_server_command_dup
656 Same type of functions added to the client library for the same
659 * Removed the cmd_ident from IDListData away since it is now
660 global for all connections. It is the command identifier used
661 in command sending and with pending commands. The affected file
664 * Added reference counter to the SilcSocketConnection objecet to
665 indicate the usage count of the object. The object won't be
666 freed untill the reference counter hits zero. Currently only
667 server uses this, and client ignores it. The client must be
668 set to use this too later. The affected files are
669 lib/silccore/silcsockconn.[ch]. Added also the function
670 silc_socket_dup to increase the reference counter.
672 This was mainly added because it is possible that the socket
673 is removed underneath of pending command or other async
674 operation. Now it won't be free'd and proper DISCONNECTING
675 flags, etc. can be set to avoid sending data to connection that
676 is not valid anymore.
678 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
679 the connection. After that it sets SILC_SET_DISCONNECTED.
680 It is, however, possible that the socket data is not still freed.
681 The silc_server_packet_process now checks that data is not
682 read or written to connection that is DISCONNECTED. The socket
683 get's freed when the reference counter hits zero.
685 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
687 * Changed the client operation API: channel_message operation's
688 `sender' is now the client entry of the sender, not the nickname
689 and the `channel' is the channel entry, not the channel name.
691 In the private_message operation the `sender' is now also the
692 client entry of the sender not the nickname.
694 Affected file is lib/silcclient/ops.h and all applications
695 using the client operations.
697 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
699 * Moved the calling of ops->connect() from connect_to_server_final
700 into receive_new_id functin since that is the point when the
701 client is actually allowed to send traffic to network. The
702 affected file is lib/silcclient/client.c.
704 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
706 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
707 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
708 (if needs broadcasting) instead of broadcasting the packets one
709 by one which would make a burst in the network traffic.
711 * Added `broadcast' argument to the functions in silcd/server.[ch]
712 silc_server_create_new_channel[_with_id] to indicate whether
713 to send New Channel packet to primary router.
715 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
717 * Added new function into the silcd/server.[ch] files:
718 silc_server_create_new_channel_with_id to create new channel with
719 already existing Channel ID.
721 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
722 lib/silccore/silcpacket.h. This packet is used t send list of
723 Set Mode payloads inside one packet. Server uses this to set
724 the modes for the channels and clients on those channels, that it
725 announced to the router when it connected to it. The protocol
726 specification has been updated accordingly.
728 * The silc_server_new_channel did not handle the packet coming
729 from normal server as it normally does not send that. However,
730 when it announces its channels it does send it. Implemented
731 the support for that.
733 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
734 into the file lib/silccore/id.h.
736 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
738 * Fixed memory leaks in the functions silc_idlist_del_client,
739 silc_idlist_del_channel and silc_idlist_del_server in the file
740 silcd/idlist.c. All of those leaked like a sieve.
742 * Fixed some small memory leaks in the client's function
743 silc_client_notify_by_server.
745 * Added functions into silcd/server.c: silc_server_announce_clients,
746 silc_server_announce_channels and silc_server_announce_server.
747 These functions are used by normal and router server to announce
748 to its primary router about clients, channels and servers (when
749 router) that we own. This is done after we've connected to the
752 These functions effectively implements the following packet types:
753 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
754 and SILC_PACKET_NEW_ID_LIST.
756 * Added new functions into the silcd/packet_receive.[ch]:
757 silc_server_new_id_list, silc_server_new_channel_list and
758 silc_server_new_channel_user_list to handle the incoming
759 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
761 * Added support of changing Channel ID in the function
762 silc_server_replace_id. If the server that announces a channel
763 to the router already exists in the router (with same name but
764 with different Channel ID), router is responsible to send
765 Replace ID packet to the server and force the server to change
766 the Channel ID to the one router has.
768 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
769 client that the Channel ID has been changed by the router. The
770 normal server sends this to the client. Client must start using
771 the new Channel ID as the channel's ID.
773 Implemented handling of this new type into lib/silcclient/client.c
774 into the function silc_client_notify_by_server.
776 * Added new function silc_idlist_replace_channel_id into the files
777 silcd/idlist.[ch] to replace the Channel ID.
779 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
781 * Call silc_server_command_identify_check always when processing
782 the IDENTIFY command in silcd/command.c
784 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
786 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
787 send keepalive packets. The packet can be sent by clients,
790 Added function silc_socket_set_heartbeat into the file
791 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
792 If not set, the heartbeat is not performed. The actual
793 heartbeat is implemented in the low level socket connection
794 library. However, application is responsible of actually
797 Added silc_server_send_heartbeat to send the actual heartbeat
798 packet into silcd/packet_send.[ch]. Server now performs
799 keepalive with all connections.
801 * Added silc_task_get_first function into lib/silcutil/silctask.c
802 to return the timeout task with shortest timeout. There was a bug
803 in task unregistration that caused problems. TODO has been
804 updated to include that task system must be rewritten.
806 * The client library will now resolve the client information when
807 receiving JOIN notify from server for client that we know but
808 have incomplete information.
810 * Rewrote parts of silc_server_remove_from_channels and
811 silc_server_remove_from_one_channel as they did not remove the
812 channel in some circumstances even though they should've.
814 * Encryption problem encountered in server:
816 The LEAVE command used to send the Channel Key packet to the
817 router immediately after generating it. However, the code
818 had earlier sent Remove Channel user packet but not immediately,
819 ie. it was put to queue. The order of packets in the router
820 was that Channel Key packet was first and Remove Channel User
821 packet was second, even though they were encrypted in the
822 reverse order. For this reason, MAC check failed. Now, this
823 is fixed by not sending the Channel Key packet immediately but
824 putting it to queue. However, this is more fundamental problem:
825 packets that are in queue should actually not be encrypted
826 because packets that are sent immediately gets encrypted
827 actually with wrong IV (and thus MAC check fails). So, packets
828 that are in queue should be encrypted when they are sent to
829 the wire and not when they put to the queue.
831 However, the problem is that the current system has not been
832 designed to work that way. Instead, the packet is encrypted
833 as soon as possible and left to the queue. The queue is then
834 just purged into wire. There won't be any fixes for this
835 any time soon. So, the current semantic for packet sending
838 o If you send packet to remote host and do not force the send
839 (the packet will be in queue) then all subsequent packets to the
840 same remote host must also be put to the queue. Only after the
841 queue has been purged is it safe again to force the packet
844 o If you send all packets immediately then it safe to send
845 any of subsequent packets through the queue, however, after
846 the first packet is put to queue then any subsequent packets
847 must also be put to the queue.
849 Follow these rules and everything works fine.
851 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
853 * Added new function silc_server_remove_clients_by_server to
854 remove all client entries from ID list when the server connection
855 is lost. In this case it is also important to invalidate all
856 client entires as they hold the invalid server entry. This
857 fixes fatal bug when server has lost connection and will reconnect
860 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
862 * Made some sanity checks to silc_server_daemonise like to check
863 whether the requested user and group actually exists.
865 * Added sanity check to SKE's silc_ske_responder_finish to check
866 that the public and private key actually is valid.
868 * Invalidate the client's nickname when receiving Replace ID
869 packet and the Client ID is being replaced. This means that the
870 server will query the nickname if someone needs it (client)
873 * Sort the ID Cache in client library when the ID Cache data
874 has changed (needs sorting).
876 * Do not allow for SILC client to create several connections to
877 several servers. The client does not support windows right now
878 and generating multiple connections causes weird behaviour.
880 Irssi-silc client does support windows and can handle several
881 connections without problems, see: www.irssi.org and SILC plugin.
883 * Fixed some places where client was added to the IDList. The
884 rule of thumb is following (in order to get everything right):
885 If the client is directly connected local client then the
886 `connection' argument must be set and `router' argument must be
887 NULL to silc_idlist_add_client function. If the client is not
888 directly connected client then the `router' argument must
889 bet set and the `connection' argument must be NULL to the
890 silc_idlist_add_client function.
892 * The funtion silc_server_packet_send_local_channel actually did
893 not check whether the client was locally connected or not. It
894 does that now. Fixed a bug related to LEAVE command.
896 * Fixed Remove Channel User payload parsing bug in server's
897 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
899 * The server's silc_server_save_channel_key now checks also the
900 global ID list for the channel as it might not be in the local
901 list. Fixed a bug related to LEAVE command.
903 * Is this the end of the [<unknown>] buglet that has been lurking
904 around for a long time? A little for loop fix in server's
905 silc_server_command_whois_parse that is used by both IDENTIFY
906 and WHOIS command. At least, this was a clear bug and a cause
907 of one type of [<unknown>] buglet.
909 * WHOIS and IDENTIFY commands call the function
910 silc_server_command_[whois/identify]_check function even if
911 we are not router server.
913 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
915 * Added --with-gmp configuration option. If set the GMP
916 is always compiled in the SILC source tree. If not set then
917 it is checked whether the system has the GMP3 installed. If
918 it has then the GMP won't be compiled (the system's headers
919 and library is used), if it doesn't have it then the GMP is
920 compiled in the SILC source tree.
922 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
924 * Changed RSA private exponent generation to what PKCS #1
925 suggests. We try to find the smallest possible d by doing
926 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
927 not security fix but optimization.
929 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
931 * Added new config entry [Identity] to fork the server and run
932 it as specific user and group. A patch from Bostik.
934 * Imported Dotconf configuration library into lib/dotconf.
935 This will be used to create the SILC configuration files later.
936 It will appear in the distsribution after this commit.
938 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
940 * A big code auditing weekend happening. Auditing code for
941 obvious mistakes, bugs and errors. Also, removing any code
944 Removed files for being obsolete:
946 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
947 inline in the file lib/silcutil/silcbuffer.h)
949 o lib/silcutil/silcbufutil.c (the header has inline versions)
951 Changed code to fix possible error conditions:
953 o The buffer formatting routines now check that the destination
954 buffer really has enough space to add the data. This applies for
955 both buffer formatting and unformatting
956 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
957 unformatting was changed to accomodate following rules:
958 XXX_*STRING_ALLOC will allocate space for the data into the pointer
959 sent to the function while XXX_*STRING will not allocate or copy
960 the data into the buffer. Instead it sets the pointer from the
961 buffer into the pointer sent as argument (XXX_*STRING used to
962 require that the pointer must be allocated already). This change
963 makes this whole thing a bit more consistent and more optimized
964 (note that the data returned in the unformatting with XXX_*STRING
965 must not be freed now). The routines return now -1 on error.
967 o Tried to find all code that use buffer_format and buffer_unformat
968 and added return value checking to prevent formatting and
969 especially unformatting errors and possible subsequent fatal
972 o Changed ske->x and ske->KEY to mallocated pointers in
973 lib/silcske/silcske.h. Fixed possible data and memory leak.
975 o Added return value checking to all *_parse* functions. Fixed
976 many memory leaks as well.
978 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
979 so that buffer overflows would not happen. All code now also
980 checks the return value as it can fail.
982 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
984 * Added reconnection support to server if the normal server looses
985 its connection to the router (for example if router is rebooted).
986 The server performs normal reconnection strategy implemented
987 to the server. Affected file silcd/server.c.
989 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
991 * Added new packet type SILC_PACKET_SET_MODE that is used to
992 distribute the information about changed modes (for clients,
993 channels and clients channel modes) to all routers in the
994 network. Updated the protocol specification accordingly.
996 Added functions into silcd/packet_send.c and
997 silcd/packet_receive.c: silc_server_send_set_mode,
998 silc_server_set_mode.
1000 Added new files silcmode.[ch] into lib/silccore that implements
1001 the encoding and decoding of Set Mode Payload. Added new type
1002 SilcSetModePayload. Moved the definitions of different modes
1003 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
1005 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1007 * Oops, a little mistake in server's connection authentication
1008 protocol. The protocol is not ended with FAILURE but with
1009 SUCCESS if the authentication is Ok. :) Affected file is
1012 * Implemented NICK_CHANGE notify handling in server in the file
1013 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
1014 the local clients on the channel. After the changing nickname
1015 in router environment snhould work and the [<unknown>] nickname
1016 should appear no more.
1018 The silc_server_replace_id function that receives the Replace ID
1019 payload now sends the NICK_CHANGE notify type also in the file
1020 silcd/packet_receive.c
1022 * Changed WHOIS and IDENTIFY command to support the maximum amount
1023 of arguments defined in protocol specs (3328 arguments). This
1024 fixed a bug that caused problems when there were more than three
1027 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1029 * Added extra parameter, command identifier, to the
1030 silc_client_send_command so that explicit command identifier
1033 Changed that ID list routines uses specific command identifier
1034 when sending WHOIS/IDENTIFY requests to the server so that they
1035 can be identified when the reply comes back.
1037 Affected files lib/silcclient/command.[ch],
1038 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
1040 * Added `sender' argument to silc_server_packet_send_to_channel
1041 to indicaet the sender who originally sent the packet to us
1042 that we are now re-sending. Ignored if NULL. Affected file
1043 silcd/packet_send.[ch].
1045 * Added some server statistics support in silcd/server_internal.h
1046 SilcServerStatistics structure and around the server code. Also
1047 send some nice statistics information when client is connecting
1050 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1052 * Fixed channel ID decoding in server's JOIN command reply in
1053 silcd/command_reply.c
1055 * Fixed braodcasting of replace ID payload to not to send it if
1056 we are standalone server in silcd/packet_receive.c.
1058 * Fixed all channel message sending routines to not to send
1059 packets to clients that has router set, since they are routed
1060 separately in the same function earlier. Affects file
1061 silcd/packet_send.c and all channel packet sending functions.
1063 * In USERS reply, res_argv[i] are not allocated, the table
1064 is allocated. Thus changed that free the table, not its
1067 * In server's whois_check and identify_check if the client is
1068 locally connected do not send any WHOIS commands - they are not
1071 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1073 * Fixed some minor bugs in client when sending WHOIS command. The
1074 arguments was in wrong order.
1076 * Removed statis function add_to_channel from server in
1077 silcd/command.c that was previously used with the joining but
1080 * Tested USERS command in router environment successfully with two
1081 routers, two servers and two clients.
1083 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1085 * Reorganized the USERS command and command reply in client library
1086 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
1087 When the command is given by user we register a pending command
1088 callback that will reprocess the command after the reply has been
1089 received from the server. When reprocessing the packet we then
1090 display the information. Thus, the USERS information is displayed
1091 now in the command callback instead of in the command reply
1092 callback. The processing of the command is same as previously
1093 when server has sent the command reply in the JOINing process.
1095 * Added to USERS command in silcd/command_reply.c to join the client,
1096 we didn't use to know about, to the channel after we've created
1097 a client entry for it. Also, for clienet we did know already still
1098 check whether it is on the channel or not and add it if not.
1100 * Removed silc_server_command_join_notify as the function and its
1103 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1105 * Changed the client's pending command handling to the same as the
1106 server's pending command handling. It is also now possible to
1107 execute command reply functions from other command reply
1108 function as the function callbacks for commands and command
1109 replies are one and same. The pending commands are not static
1110 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
1111 in client connection context. Thus, pending commands are server
1112 connection specific as it is convenient.
1114 Changed the function silc_client_command_pending and
1115 silc_client_command_pending_del and added new function
1116 silc_client_command_pending_check. Removed the
1117 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
1120 * Added cmd_ident, current command identifier, to the client
1121 connection context in lib/silcclient/client.h to keep track on
1122 command identifiers used in command sending. Client's command reply
1123 function handling now supports the mandatory command identifiers.
1125 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
1126 funtions in client to fully support pending command callbacks.
1128 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
1129 as one of the arguments to the application in the command reply
1132 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1133 before first releasing SILC but came back. Now it is removed again
1134 and should come back nomore. The FORWARDED flag was used only
1135 by the JOINing procedure by forwarding the command packet to router.
1136 Now, the JOINing procedure has been changed to more generic (due
1137 to various router environment issues) and FORWARDED is not needed
1138 anymore for anything. The protocol specification is yet to be
1141 Now, removed silc_server_packet_forward from server and the flag
1142 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1144 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1146 * Renamed NAMES command to USERS command. The NAMES was named that
1147 due to historical reasons. Now it is renamed. Also, rewrote
1148 parts of the USERS command. The nickname list is not sent anymore
1149 by the server. Only Client ID and mode lists are sent in the USERS
1150 command. Changed this also to the protocol specification.
1152 The client now resolves the names and stuff after it receives
1153 the USERS list from the server when joining to the channel.
1155 * WHOIS and IDENTIFY commands has been changed to support multiple
1156 Client ID's per command. One can now search for multiple users
1157 in the network by sending only one WHOIS or IDENTIFY command.
1158 Changed the code and the protocol specifications.
1160 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1161 uses silc_server_command_whois_parse to parse the request. */
1163 * If normal server, do not parse the WHOIS and IDENTIFY requests
1164 before sending it to the router. Saves some time.
1166 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1168 * Fixed JOIN command on client library. Wrong number of arguments
1169 used to crash the client.
1171 * Added silc_server_channel_has_global function to check whether
1172 channel has global users or not.
1174 * Added silc_server_channel_has_local function to check whether channel
1175 has locally connected clients on the channel.
1177 * The silc_server_remove_from_one_channel now checks whether the
1178 channel has global users or not after given client was removed from
1179 the channel. It also checks whether the channel has local clients
1180 on the channel anymore. If it does not have then the channel entry
1181 is removed as it is not needed anymore.
1183 * The silc_server_notify now checks on JOIN notify whether the joining
1184 client is one of locally connected or global. If it is global then
1185 the channel has now global users on the channel and that is marked
1186 to the channel entry. Also, it now saves the global client to
1187 global list who is joining and JOINs it to the channel. This is
1188 for normal server, that is.
1190 Changed silc_server_send_notify_on_channel,
1191 silc_server_packet_relay_to_channel and
1192 silc_server_packet_send_to_channel check if we are normal server
1193 and client has router set (ie. global client) do not send the
1194 message to that client, as it is already routed to our router.
1196 * Implemented LEAVE notify type handling in silc_server_notify
1199 * Tested LEAVE command in router environment successfully. Tested
1200 with two routers, two servers and two clients.
1204 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1206 * Implemented SIGNOFF notify type handling in silc_server_notify
1209 * silc_server_remove_id now removes the client entry from all channels
1210 it has joined and thusly sends SIGNOFF notify type.
1212 * Rewrote the NAMES list generation in server by removing two excess
1213 loops. The lists are created now inside one loop.
1215 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1217 * silc_server_remove_channel_user checks now also global list
1218 for channel and client.
1220 * silc_server_new_channel_user checks now both local and global
1221 list for channel and client. Fixed a bug in client id decoding.
1222 Used to decode wrong buffer.
1224 * silc_server_channel_message checks now both local and global
1225 list for channel entry.
1227 * Tested channel joining (hence JOIN) in router environment
1228 successfully. Tested with two routers, two servers and two
1231 * Tested channel message sending in router environment successfully.
1233 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1235 * Added silc_server_save_channel_key into server.[ch] to save the
1236 received channel key in Channel Key payload processing. It is
1237 also used in JOIN command reply handling.
1239 Equivalent function silc_client_save_channel_key added into
1240 client.[ch] into client library.
1242 * Changed JOIN command reply to send information whether the channel
1243 was created or not (is existing already) and the channel key
1244 payload. Changed protocol specs accordingly.
1246 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1247 the request was sent by ID and not by nickname. Crashed on
1250 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1252 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1253 now correctly save the received data.
1255 * silc_server_free_sock_user_data now notifies routers in the
1256 network about entities leaving the network.
1258 At the same time implemented functions silc_server_remove_id
1259 and silc_server_send_remove_id to receive and send REMOVE_ID
1260 packets. The packet is used to notify routers in the network
1261 about leaving entities. The ID removed will become invalid in
1264 * Added function silc_idlist_del_server into server. Removes and
1265 free's server entry from ID list.
1267 * silc_server_private_message function now checks, if we are router,
1268 that the destination ID really is valid ID, naturally.
1270 * In router when NEW_ID packet is received (for new client) the
1271 hash of the Client ID is saved in the ID Cache but the
1272 client->nickname is set to NULL, instead of putting the hash
1275 IDENTIFY command now also checks that client->nickname must be
1276 valid. If it is not if will request the data from the server who
1277 owns the client. Added new function
1278 silc_server_command_identify_check.
1280 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1281 to set the command to already allocated Command Payload.
1283 * Tested private message sending in router environment with two
1284 routers, two servers and two clients. Fixed minor bugs and now
1287 * Fixed segfault from client's NAMES command. Used to crash if
1290 * Forwarded packets must not be routed even if it is not destined
1291 to the receiver. Changed server code comply with this.
1293 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1295 * Added `require_reverse_mapping' boolean value to ServerParams
1296 structure. If TRUE (not default) the server will require that
1297 the connecting host has fully qualified domain name.
1299 If the reverse mapping is not required and hostname could not be
1300 found the IP address is used as hostname.
1302 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1304 * Implemented version string checking to both client and server.
1305 The check is incomplete currently due to the abnormal version
1306 strings used in development version of SILC.
1308 * Changed all command functions in server to use the new
1311 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1313 * Changed char *data to unsigned char *data in ID Cache system to
1314 support binary data as ID Cache data. Changed code to support
1315 binary data in lib/silccore/idcache.c.
1317 * Renamed silc_server_packet_relay_command_reply to
1318 silc_server_command_reply as it is normal packet receiving
1319 function. Rewrote the function to accept command replys for
1320 servers and not only for clients.
1322 * Mark remote router always as registered server if we are connecting
1323 to it. Otherwise, commands sent by the router to us are ignored.
1325 * All ID List find routines now returns the ID Cache Entry pointer
1326 as well if requested.
1328 * WHOIS command works now in router environment, tested with two
1329 routers, two servers and two clients.
1331 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1332 in router environment (as it is almost equivalent to WHOIS) but
1333 hasn't been tested thoroughly. Added new functions:
1335 silc_server_command_identify_parse
1336 silc_server_command_identify_send_reply
1337 silc_server_command_identify_from_client
1338 silc_server_command_identify_from_server
1340 * Disabled route cache adding because adding two different ID's with
1341 same IP replaces the old cache entry thus giving wrong route.
1342 The entry->router->connection is always the fastest route anyway
1343 so route cache may not be needed. Of course, new routes maybe
1344 established after receiving the ID when the entry->router->connection
1345 might not be anymore the most optimal.
1347 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1349 * Add route cache for received ID for fast routing.
1351 * Added silc_server_packet_route to route received packet on router
1352 that is not destined to us.
1354 * Renamed silc_server_get_route to silc_server_route_get.
1356 * Added id_string and id_string_len fields into SilcServer to
1357 include encoded ServerID for fast comparing without excess
1358 encoding of the ID's.
1360 * Cleaned up WHOIS command on server side. Added following static
1363 silc_server_command_whois_parse
1364 silc_server_command_whois_check
1365 silc_server_command_whois_send_reply
1366 silc_server_command_whois_from_client
1367 silc_server_command_whois_from_server
1369 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1370 arguments in command replies. All command functions should be
1371 updated to use this macro.
1373 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1375 * Minor typo fixes on command reply handling on server.
1377 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1379 * Added silc_server_command_add_to_channel internal routine to add
1380 the client to the channel after router has created the channel and
1381 sent command reply to the server.
1383 * Added generic silc_server_send_command to send any command from
1386 * Use static buffer with ID rendering instead of duplicating data.
1388 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1390 * Fixed a channel user mode bug when joining to a channel server gave
1391 everybody channel founder rights, oops.
1393 * We mark ourselves as the router of the incoming server connection
1394 if we are router ourselves. This way we can check in some packet
1395 sending functions whether it is locally connected server. For
1396 incoming router connections we put NULL.
1398 * For router sending packets locally means now always sending the
1399 packet cell wide; to local clients and local servers. For normal
1400 server sending packet locally means sending it to only local
1403 * Fixed the JOIN command to really work in router environment. If the
1404 channel is created it is always created by the router. Router is
1405 also responsible of making the initial joining to the channel,
1406 sending JOIN notify to the sending server and distributing
1407 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1408 does not exist server doesn't do anything else but forward the
1409 command to the router which performs everything.
1411 * Added silc_server_send_channel_key function to send the Channel Key
1414 * Added silc_server_create_channel_key to create new channel key. The
1415 channel key is now re-generated everytime someone joins or leaves
1416 a channel, as protocol dictates. Note: channel->key_len is the
1419 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1421 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1422 packet_receive.[ch] to separate packet sending and receiving
1423 routines. The server.[ch] now includes everything else including
1424 actual packet processing (writing and reading data) and other
1427 Renamed silc_server_private_message_send_internal to
1428 silc_server_send_private_message. The routine is still though
1429 used only to relay private messages as server does not send
1430 private messages itself.
1432 Renamed silc_server_new_channel to silc_server_create_new_channel
1433 and added new function sicl_server_new_channel that handles the
1434 incoming New Channel packet. Added also new sending function
1435 silc_server_send_new_channel to send New Channel Payload.
1437 * Added new function silc_server_notify to process incoming notify
1438 packet to the server/router. Server may then relay the notify
1439 to clients if needed.
1441 * Added new function silc_server_new_channel_user to process incoming
1442 New Channel User packet. Router will redistribute the packet and
1443 send JOIN notify to its local clients and locally connected servers
1444 if needed. Normal server will send JOIN notify to its local client
1445 on same channel when received this packet. Added also corresponding
1446 sending function silc_server_send_new_channel_user to sent the
1449 * Added boolean route argument to send_notif_to_channel and
1450 packet_send_to_channel functions to attempt to route the packet
1451 if it is TRUE and send only locally if it is FALSE.
1453 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1455 * silc_server_replace_id now broadcasts the received replace ID
1456 packet if it is not broadcast packet already. The router must
1457 broadcast to inform other routers about changed ID.
1459 * Added backpointer to server's router into SilcServer context in
1460 silcd/server_internal.h.
1462 * Fixed silc_server_packet_broadcast to send correct broadcast
1465 * The channel key is now distributed to the local client as soon
1466 as it is received from the router (in router environment) so that
1467 no other packet may be sent for the channel until client has
1470 * silc_server_remove_channel_user now broadcasts the received
1471 Remove Channel User packet if it is not broadcast packet already.
1472 The router must broadcast to inform other routers about removed
1475 * Added users field into SilcPacketContext that is a reference count
1476 of the context. One can increase the reference count by calling
1477 silc_packet_context_dup which is now changed to just increase the
1478 reference count instead of duplicating the data. The reference
1479 count is decresed by calling silc_packet_context_free that will
1480 free the data after the reference count hits zero.
1482 For now on the packet context and everything allocated into it
1483 (including the raw packet from network) must be freed by calling
1484 the new silc_packet_context_free function. Added also new function
1485 silc_packet_context_alloc that must be used now to allocate the
1486 context. This also means that if a routine is asynchronous from
1487 silc_[client/server]_packet_parse_type the packet context must
1488 be duplicated by calling silc_packet_context_dup. Otherwise it
1489 gets free'd after silc_[client/server]_packet_parse_type returns.
1490 Also, one must remember that if packet is duplicated then its
1491 reference count must be decresed by calling the free function as
1492 many times as it was duplicated.
1494 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1495 from both client and server.
1497 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1499 * Made joining to a channel working in router environment.
1501 * Cleaned up JOIN command on server side and create function
1502 silc_server_command_join_channel internal routine to make the
1505 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1507 * Changed silc_command_pending list to SilcDList. Also, added
1508 `ident' field to SilcServerCommandPending structure to identify
1509 the reply and to call correct callback.
1511 Added silc_server_command_pending_check function to replace the
1512 corresnponding macro. The silc_command_pending list is not
1515 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1516 to set identifier to previously allocated Command Payload. It
1517 is used to set identifier for command when resending Command
1520 * Added silc_command_payload_encode_payload to encode Command
1521 Payload buffer from SilcCommandPayload structure.
1523 * Added silc_argument_payload_encode_payload to encode Argument
1524 payload buffer from SilcArgumentPayload structure.
1526 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1528 * Changed WHOIS command to support router connection on server side.
1529 The whois request is always sent to router unless the server is
1530 standalone server. After server has received the reply from the
1531 router will it send the reply to the client.
1533 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1534 broadcast received broadcast packet. The function is used only
1535 by router. The broadcast packet is always sent to the router's
1538 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1539 render given ID to printable string, for log files for example.
1541 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1543 * Made basic router to router connections working. At least they
1544 can now connect to each other but nothing really works the way
1545 they are supposed - yet.
1547 * Added new initiator token to RouterConnection configuration
1548 file in silcd/serverconfig.[ch]. It is used to tell whether we
1549 are the initiator to the remote router or whether we'll expect
1550 the other end to connect.
1552 * Moved registering of listener task to silc_server_init, hence
1553 the server starts listenning as soon as it is run, even if it
1554 does not have connections to other routers. Let's see how well
1557 * Changed default connection retry timeouts for more suitable in
1560 * Removed cipher and such arguments from silc_idlist_add_client
1561 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1562 Added new function silc_idlist_add_data to add the keys and stuff
1565 * Added SilcIDListData structure and added it to SilcClientEntry
1566 and SilcServerEntry as their first field in the structure. This
1567 way we can explicitly cast the ID entries to the SilcIDListData
1568 structure and get common data for the entries. In past, we had
1569 to first check what type of connection it is and then cast it to
1570 correct ID entry type. Now, we can directly cast the opaque
1571 pointer to the SilcIDListData (no matter what ID entry it actually
1572 is) and get the data needed.
1574 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1576 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1577 in some circumstances even if threre were timeout tasks, though not
1578 IO tasks, but tasks anyway. Now fixed.
1580 * Defined SilcServerConnection structure to hold connection specific
1581 stuff about directly connected servers and routers. The definition
1582 is currently in silcd/server_internal.h. I thought about having
1583 a bit more important role fro this struct but for now it is used
1584 only when connecting to other server (or router actually).
1586 * Added connecting retry support in server when connecting to
1587 router(s). The retry feature implement exponential backoff
1588 algorithm. Also, added SilcServerParams structure to hold default
1589 parameters for server. For now, it include these retry settings
1590 and are hard coded. After server is moded to be as Silc Server
1591 Library this structure will be more important.
1593 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1595 * Changed client librarys channel->clients table to SilcList and
1596 changed code accordingly.
1598 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1600 * Changed client's channel table to SilcList and changed code
1601 accordingly. Also changed SilcChannelClientEntry to include back-
1602 pointer to the channel so that client entry can use that structure
1603 as list as well and we have fast cross-reference to the channel.
1604 This change dramatically decreased the complexity of channel
1605 handling with client entry and vice versa (removed one extra
1606 loop when searching for channel entry from many functions).
1608 * Changed server->sim from table to SilcDList and changed code
1611 * NAMES command can now be used from user interface. It will show
1612 the user list on the channel, neatly.
1614 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1615 Code now saves realname of the user if it becomes available.
1617 * Renamed configure.in to configure.in.pre and made ./prepare
1618 script to automatically add correct version string to
1619 configure.in which it creates from configure.in.pre.
1621 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1623 * NAMES command reply now shows users mode with the nickname when
1626 * Moved silc_client_ch[u]mode[_char] functions from
1627 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1628 place sucks, they are utility functions and should be in some
1631 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1633 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1636 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1640 * Added TRQ (efficient deque and list library) into lib/trq. This is
1641 a very good list library that is currently used in the SILC. Defined
1642 SilcList API over the library because I didn't like the API very
1643 much. See lib/trq/silclist.h for the API and examples of how to
1644 use the API. Fixed various places in the code to use the new
1645 SilcList API. The SilcList is meant for lists that has a structure
1646 already defined as a list. It is not suitable to add just some
1647 context to the list (in TRQ, the context is the list actually).
1649 So, I defined SilcDList that can be used for the purpose where
1650 predefined list structure does not exit. This can be used as
1651 such list. Now some context just can be added to the SilcDList.
1652 Currently this list is not used in the SILC just yet, though there
1653 are a lot places where this can replace dynamically allocated
1654 tables and I will fix these places, later, to use SilcDList.
1655 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1656 and use TRQ internally).
1658 Also fixed some annoying warning messages that the original TRQ
1659 code generated. Also minor changes to TRQ's Makefile.in.
1661 * Added support for querying by Client ID to both WHOIS and
1662 IDENTIFY commands into server, as required by the protocol.
1664 * Removed method function pointers from SilcBuffer structure. They
1665 weren't used to anything and just increased the context size for
1666 no good reason. This change also made silc_buffer_alloc and
1667 silc_buffer_free functions inline functions.
1669 * Disabled command flooding detection support until it's fixed so
1670 that it accepts commands in but does not execute them more than once
1673 * Added silc_net_localhost(), to return local hostname, into
1674 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1675 that must be initialized before calling silc_client_init.
1677 * Added new function: silc_server_send_notify_on_channels to send
1678 notify messages to all channels client has joined. It is assured
1679 that the message is sent only once per client.
1681 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1682 lib/silcutil/silcutil.[ch] as silc_format function. The new
1683 function is generic and is used by server as well, not only by
1684 the logging routines.
1686 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1687 the provided version string was not acceptable. Added new function:
1688 silc_ske_check_version into lib/silcske/silcske.h. The function
1689 must be implemented by the application (client or server) and it
1690 does not reside in the SKE library. The function checks the version
1691 string remote end sent.
1693 * Added back pointers (to opaque context and to SilcSocketConnection)
1694 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1696 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1697 duplicate packet context structure.
1699 * Changed `notify' client operation to send same arguments as client
1700 receives from server except for ID's. ID's are mapped to correct
1701 ID entry and that is returned. Also, if channel entry is not sent
1702 by server but the notify is for channel the channel entry is sent
1703 to application (otherwise application doesn't know that it is for
1704 channel (library gets it from packet's Destination ID)).
1706 * Added silc_client_remove_from_channels into client library to
1707 remove a client from all channels it has joined to. Used when
1708 received SIGNOFF notify from server. Added also new function
1709 silc_client_replace_from_channels to replace old ID entry with
1710 new ID entry on all channels. Used when received NICK_CHANGE
1713 * Fixed ID Cache list handling in silc_idlist_get_client in
1714 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1715 to get (or query) client by ID.
1717 * Updated TODO list.
1719 * Added connection authentication status message defined by the
1720 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1721 support for these into the code in client and server side.
1723 * Added generic function silc_client_send_command to send any command
1724 with variable argument list. Application should use this function
1725 to send commands if the command functions provided by the library
1726 does not suite for the application's user interface needs.
1728 * Added new `failure' client operation. Application is notified about
1729 received failure packet if client is executing a protocol. In this
1730 case the protocol's execution has failed.
1732 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1733 is required by the protocol.
1735 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1736 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1739 * Added status flag to SilcSKE object to indicate realtime status
1740 of the SKE protocol.
1742 * Application receives now exactly same command reply arguments as
1743 the library receives from server. However, if ID is received the
1744 corresponding ID entry is returned to the application (eg. Client
1745 ID is mapped to correct SilcClientEntry entry and that is returned).
1746 Changed command_reply client operation due to this change.
1748 * Changed all ID's in commands and in command replys as ID Payloads.
1749 Change affected both client and server side codes.
1751 All ID's sent in SILC network (with execption of ID's in SILC
1752 Packet header) are sent in ID Payload to support variable length
1755 * Server now notifies nick changes and notifies all clients on
1756 the channels about the new nickname (about the new Client ID,
1759 * Implemented CMODE command to change channel modes. Supports all
1760 channel modes defined by the protocol specs except ban and invite
1761 lists. (Also, private channel key mode is supported but support for
1762 setting private channel key in client is missing, thus, this mode
1763 has no effect on client side (except that server requires that the
1764 client uses private channel key and normal channel traffic does not
1767 Also, invite mode works per se, but INVITE command does not work
1768 yet correctly, so you can set channel as invite only channel but
1769 inviting clients to the channel does not work (it is yet to be
1770 thought what's the best way to do it).
1772 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1773 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1774 Implemented CUMODE command to change user's mode on the channel.
1775 Supports all modes defined by the protocol specs.
1777 * Added NAMES command reply to return users modes on the channel.
1779 * Removed unnecessary and slow ciphers from lib/silccrypt.
1781 * Set SO_KEEPALIVE option to connection sockets by default.
1783 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1785 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1786 redefined the Notify Payload into protocol specs.
1788 * Added silc_id_payload_parse_id to get ID directly from raw
1791 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1793 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1794 accept searching by Client ID as well.
1796 * Added support for LEAVE and SIGNOFF notify types in client library.
1798 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1799 to parse ID Payload from raw data.
1801 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1803 * Added flags parameter into silc_ske_assemble_security_properties
1804 function in lib/silcske/silcske.[ch].
1806 * Changed notify client operation to fit better for notify messages
1807 sent by server. The notify payload received from server is now
1808 passed to the application (after parsing it to SilcNotifyPayload).
1809 It is application's responsibility to retrieve the arguments
1810 from the payload and show the message the way it wants. The message
1811 sent by server is implementation specific.
1813 * Changed public keys to comply with the protocol specification.
1814 Old public keys are not supported anymore and are not compatible.
1816 * Removed nickname from Channel Payload as the latest draft removed
1817 it. The client must resolve the nickname from the NAMES command
1818 reply received when it joined the channel.
1820 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1822 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1824 * Fixed some errors in protocol specification drafts.
1826 * Created lib/silccore/silcnotify.c to implement Notify Payload
1827 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1828 generic payloads described by protocol specifications. The file
1829 includes implementations for ID Payload and Argument Payload.
1831 * Changed Command Payload implementation to use the new Argument
1832 Payload. Changed command_xxxx_payload to command_payload_xxxx
1833 to comply with SILC coding conventions.
1835 * Added suppport for Argument Payload handling in Notify Payload
1836 implementation as protocol requires it. Added the new support
1837 into server and client lib as well.
1839 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1841 * Added support for multiple nicknames on same channel. [n] is
1842 added locally to the nickname if there are more than one same
1843 nicknames on the channel.
1845 * Server now sends all nicknames that matched WHOIS request.
1846 Client also shows the list received from server.
1848 * Added TOPIC command to client side. User can now set and show
1849 current topic on channel.
1851 * Added MOTD command to client and server. Also, server sends the
1852 motd when client connects to the server.
1854 * Changed version strings to comply ISO 8601.
1856 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1858 * Fixed protocol error handling in client library. It should now
1859 cope even if the SKE fails for some reason.
1861 * Made new protocol specification drafts for submitting to IETF.
1863 * Implemented TOPIC command to server in silcd/command.c.
1865 * Added two new notify types into lib/silccore/silcnotify.h:
1866 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1867 notify nickname change and topic setting/change on a channel.
1869 * API change of command_reply operation in client library. The
1870 application gets now the status type received from server as well.
1872 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1874 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1876 * Cras fixed and optimized the packet handling even further and
1877 it should work now. Minor change to the prototype of function
1878 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1880 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1882 * Added new function into lib/silcutil/silcschedule.[ch]:
1883 silc_schedule_with_fd to select() a specified fd. The function
1884 returns after timeout expires or data arrives or goes. The
1885 function is used by packet routines to wait that all data is
1886 received from network.
1888 * Fixed data reading from network in lib/silccore/silcpacket.c.
1889 The code now assures that all data is read from the fd and then
1890 continues packet processing. This was a bug fix since the code
1891 used to drop some data in some circumstances.
1893 * Added new function into lib/silcclient/client.[ch]:
1894 silc_client_start_key_exchange to start key exchange after
1895 connection has been established to server. The code internally
1896 now uses this funtion but its main purpose was to provide it
1897 for applications that perform their own connecting. After
1898 application has created a connection it merely calls this
1899 function to start the key exchange between client and server.
1900 The library takes care of everything else after that.
1902 Updated also lib/silcclient/README to explain the usage of
1905 * Do not send to application information that connection has
1906 been established. Application gets notified it by connect
1909 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1911 * Applied cras's patch to add silc_schedule_one function. The
1912 function runs scheduler once and returns.
1914 * Fixed the scheduler after cras messed it up. The timeout
1915 handling works now as it's supposed to work.
1917 * Added into lib/silccore/ silcnotify.h to include notify
1918 message types support. Changed silc_server_send_notify*
1919 functions, in server.[ch], to support those new notify types.
1920 Added the support for the notify types into client library,
1921 as well. Added new notify client operation into ops.h in
1924 * Changed silc_server_packet_send_to_channel to send normal
1925 packets instead of just channel message packets. The function
1926 is now used to send the notify packets to channels. It is not
1927 used to send channel message packets anymore, as server never
1930 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1931 va_arg()s as it seems to require it nowadays. I guess, if SILC
1932 is compiled with older va_arg() the new code should work anyway.
1934 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1936 * Splitted core library. Core library (lib/silccore) includes
1937 now only SILC protocol specific core (and common) components.
1938 Created new utility library (lib/silcutil) that includes more
1939 generic purpose stuff. The stuff for util library was taken
1940 from the old core library. This was minor and easy split.
1942 * Created SILC Client Library (lib/silcclient) that includes
1943 implementation of the SILC client without user interface. This
1944 was major move from silc/ directory. The code has been changed
1945 so that it is transparent towards the user interface. The
1946 silc/ directory includes now the same user interface as before
1947 and it uses the new client library. Read lib/silcclient/README.
1948 Basicly, the client library performs everything else related
1949 to SILC except user interface handling. Also, configuration
1950 files are considered to be part of user interface and library
1951 does not handle them.
1953 This change also changed a lot of structures, function naming etc.
1954 Most important change was that SilcClientWindow object was
1955 renamed to SilcClientConnection in the client library. Created
1956 also new file lib/silcclient/ops.h. Also added new files
1957 silc/local_command.[ch] and silc/client_ops.[ch].
1959 All these changes were made to make it easier for user interface
1960 designers to create what ever user interface for the SILC client
1963 It is also expected that the server will be moved to lib
1964 directory as well and SILC Server Library will be created;
1965 sometimes in the future.
1967 * Removed Local commands from lib/silccore/silccommand.h as
1968 they are application specific and new client library does not
1969 handle any of those anymore.
1971 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1972 old client implementation in silc/.
1974 * Added support for callback functions in SILC_LOG_* macros.
1975 Application can now set its own callbacks that will be called
1976 instead of using the default functions that will always print
1977 the debug messages to stderr (or stdout). Also, debugging can
1978 now be disabled by setting silc_debug to FALSE and re-enabled by
1979 setting it to TRUE. Note, that logging will still work even
1980 if debugging is disabled.
1982 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1983 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1984 silc_log_reset_debug_callbacks.
1986 * To enable debugging in silc client one must give now -d
1987 option on command line.
1989 * Changed silc_schedule_init to automatically allocate task queues
1990 if they are not allocated before calling it.
1992 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1994 * Added GMP 3.1 into math library.
1996 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1998 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1999 a channel in SILC network. The packet is used by servers and
2000 routers to notify other routers that user has left a channel.
2001 This little feature was missing until now. Added the feature
2002 to protocol specification as well.
2004 Added functions: silc_server_send_remove_channel_user and
2005 silc_server_remove_channel_user into server.[ch].
2007 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
2008 lib/silccore/silcpacket.h. However, they are not implemented
2011 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2013 * Fixed joining to a channel and sending channel messages
2014 between server and router. The channel message sending should
2015 now work inside a cell.
2017 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2019 * Fixed the private message sending between server and router.
2020 The private message sending should now work inside a cell.
2022 * Added silc_server_replace_id into server.[ch] to replace
2023 existing ID in the SILC network.
2025 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
2026 and silc_idlist_replace_server_id into idlist.[ch] in server.
2028 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2030 * Fixed the server to server connections. Server can again now
2031 connect to router. Router to router connections probably does
2034 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2036 * Added dynamic protocol registering support. Now protocols can
2037 registered and unregistered on the fly. Patch by cras.
2039 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2041 * Added lib/contrib directory to hold routines that some platforms
2042 don't have but are needed by SILC.
2044 * Added getopt.c, getopt1.c and getopt.h from GNU C library
2045 into lin/contrib to provide getopt() and getopt_long() for
2046 those who don't have it.
2048 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2050 * Added AWAY command to client. When away message is set and
2051 client receives a private message packet the client automatically
2052 replies to the sender with the away message.
2054 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
2055 bug seemed to be the cause of recent problems when compiling
2058 * Added version detection support to SKE protocol specification
2059 and added the new changes to the SKE implementation as well.
2060 There were other minor changes in the SKE protocol as well.
2062 Many changes in lib/silcske/silcske.[ch] and in
2063 lib/silcske/payload.[ch].
2065 * Added ^U functionality, clear input line. Patch from cras.
2067 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2069 * Mainly small bugfixes on core library. Fixed some debugging
2070 logging and buffer overflow in silclog.c.
2072 * Updated config.sub and config.guess on the distribution tree.
2074 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2076 * Added command lagging support in server. Client may execute
2077 commands now only once in two seconds.
2079 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2081 * Optimized packet reception. MAC computation and checking is now
2082 also more optimized. A lot previously duplicated code is now
2083 used as generic by both client and server.
2085 * Fixed key pair generation in clientutil.c
2087 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2089 * Added into lib/silccore/silcbufutil.[ch] new function;
2090 silc_buffer_realloc.
2092 * Moved generic packet sending/encryption functions to
2093 lib/silccore/silcpacket.[ch] from client and server. Some
2094 rewriting of the functions.
2096 * Moved all generic packet reception/decryption functions to
2097 lib/silccore/silcpacket.[ch] from client and server. The
2098 packet processing is now much cleaner in both client and server.
2099 These were major changes in both client and server.
2101 * Created many common functions in server to do packet sending.
2102 Previously code were duplicated a lot, this has been removed
2105 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2107 * Rewrote major parts of the ID cache system. Don't know
2108 whether it is better now or not but at least the API is more
2111 * Major rewrite on ID cache stuff on client because of the ID
2112 cache API changes. Added idlist.c to client.
2114 * Also major rewrite on ID cache stuff on server as well.
2115 Major rewrite of idlist.[ch]. SilcXXXList's are now named
2116 SilcXXXEntry's. We won't keep anymore idlist specific pointers
2117 in hand, instead they are all put into the ID cache system now.
2118 All server_idlist_* routines uses ID cache now instead of
2119 traversing its own lists (those lists does not exist anymore).
2120 SilcIDList though still exists. Also, SilcXXXEntry's are
2123 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2125 * Finally made the SKE implementation compliant to the protocol
2126 specification. All mp integers are now binary encoded as
2127 opposed being HEX encoded.
2129 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2132 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2133 functions: silc_[encode/decode]_pem. Also added function
2134 silc_encode_pem_file to PEM encode with newlines ('\n') for
2137 * SILC public keys are now encoded either PEM or binary. Same
2138 option is for private keys as well. By default private keys
2139 are binary encoded and public keys PEM encoded. Silly HEX
2140 encoding were removed.
2142 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2143 function to create fingerprints.
2145 * Fixed a bug in SHA1; does not change the original data anymore.
2147 * Partly implemented INFO command on client and server side.
2148 Fixed CLEAR command. Changes to SERVER command; show current
2149 server(s) when giving command without arguments. Added
2150 VERSION command to client.
2152 * Added check to server that unregistered connections cannot
2153 execute commands (unless it is specificly allowed).
2155 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2157 * Fixed screen refresh.
2159 * Fixed channel joining bug from client. On some circumstances
2160 client tried to join to a channel it had already joined.
2162 * Added public key verification process into client's protocol.c.
2163 The client now verifies the public key from user and saves
2164 it into ~./silc/serverkeys/ directory.
2166 Added into: clientutil.[ch]: silc_client_verify_server_key.
2168 * Changed SKE protocol's silc_ske_initiator_finish function
2169 to accept callback function that verifies the received public
2170 key. Removed old silc_ske_verify_public_key function.
2172 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2174 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2175 silc_pkcs_private_key[_data]_set.
2177 * Made the password and public authentication more cleaner in
2178 server's protocol.c.
2180 * Removed historic and obsolete protocol `channel_auth' from
2181 both client and server.
2183 * Removed wrong way of sending command status messages from
2184 server to client in server's command.c. The old way violated
2185 protocol specification.
2187 Changes to silccore/silccommand.[ch]: removed
2188 silc_command_encode_status_payload -> not needed anymore,
2189 changed silc_command_encode_payload_va to accept extra
2190 argument on variable argument list. The argument type must
2191 now be provided to the function. Also, added new function:
2192 silc_command_encode_reply_payload_va which is same as
2193 normal command_encode_payload_va except command status type
2194 is provided as extra argument.
2196 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2198 * Added ~./silc directory handling. The directory includes the
2199 public and private keys for the client.
2201 Added silc_client_check_silc_dir, silc_client_create_identifier
2202 and silc_client_load_keys.
2204 * Implemented SILC protocol compliant public key. Added public
2205 and private key saving to and loading from files.
2207 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2208 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2209 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2210 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2211 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2213 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2214 silc_pkcs_load_[public/private]_key.
2216 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2218 * Added silc_server_get_route (route.[ch]) to get connection
2219 data for the fastest route for given ID.
2221 * Implemented INVITE command on client and server. The command
2222 were re-defined in the SILC Protocol Specification and the
2223 implementation now complies with the specification.
2225 * Implemented PING command on client and server.
2227 * Implemented NAMES command on client and server. The server side
2228 supports currently only normal server not router server yet.
2229 Some changes to NAMES definition in SILC protocol specification.
2231 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2233 * Implemented LEAVE command on client and server.
2235 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2236 again. This change was made to the protocol as well. Server
2237 should not violate the protocol specification anymore.

2241 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2242 was tested. SOCKS4 was not but should work anyway.
