3 * Minor fix t the channel payload; allocate the data area, as it
4 needs to be of specific length.
6 * If the key agreement port is zero then the operating
7 system will define the bound port. Affected files are
8 lib/silcclient/silcapi.h and lib/silcclient/client_keyagr.c.
10 Thu Mar 8 21:39:03 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
12 * Added assert()s to buffer formatting and unformatting routines
13 to assert (if --enable-debug) when error occurs. Affected
14 file: lib/silcutil/silcbuffmt.c.
16 * Changed to auto-reconnect to check whether the remote host is
17 router and register the re-connect timeout if it is. It used
18 to check that whether we are normal server, but router must do
19 auto-reconnect with another router as well. Affected file
22 * Removed the [<key len>] option from CMODE command as the cipher
23 name decides the key length, nowadays. See the defined ciphers
24 from the protocol specification.
26 * Added [<hmac>] option to the CMODE command to define the HMAC
27 for the channel. Added SILC_CMODE_HMAC channel mode.
29 * Added [<hmac>] option for the JOIN command so that user can
30 select which HMAC is used to compute the MACs of the channel
33 * Added Hmac field to the Channel Message Payload. The integrity
34 of plaintext channel messages are now protected by computing
35 MAC of the message and attaching the MAC to the payload. The
36 MAC is not encrypted. Now, it is clear that this causes some
37 overhead to the size of the packet but rationale for this is that
38 now the receiver can verify whether the channel message decrypted
39 correctly and also when private keys are set for the channel the
40 receiver can decrypt the packet with several keys and check from
41 the MAC which key decrypted the message correctly.
43 * Added silc_cipher_encrypt and silc_cipher_decrypt into the
44 lib/silccrypt/silccipher.[ch].
46 * Added silc_hash_len to return the digest length into the
47 lib/silcrypt/silchash.[ch].
49 * Rewrote parts of Silc Channel Payload interface in the
50 lib/silccore/silcchannel.[ch]. The encode function now also
51 encrypts the packet and parse function decrypts it.
53 * Channel message delivery between routers was broken after the
54 channel key distribution was fixed earlier. The channel key
55 was used be to distributed to other routers as well which is not
56 allowed by the protocol. Now this is fixed and channel keys
57 really are cell specific and the channel message delivery between
58 routers comply with the protocol specification.
60 Wed Mar 7 20:58:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
62 * Fixed a minor formatting bug in the SKE's key material processing.
63 It actually might have processed the keys wrong way resulting
66 * Redefined the mandatory HMAC algorithms and added new algorithms.
67 Added hmac-sha1-96 and hmac-md5-96 which are normal hmac-sha1
68 and hmac-md5 truncated to 96 bits. The mandatory is now
69 hmac-sha1-96. Rest are optional (including the one that used
70 to be mandatory). Rationale for this is that the truncated HMAC
71 length is sufficient from security point of view and can actually
72 make the attack against the HMAC harder. Also, the truncated
73 HMAC causes less overhead to the packets. See the RFC2104 for
76 * Added new [hmac] configuration section. The SKE used to use
77 the hash names (md5 and sha1) in the SKE proposal as HMCAS which
78 is of course wrong. The official names that must be proposed in
79 the SKE are the ones defined in the protocol specification
80 (hmac-sha1-96 for example). The user can configure any hmac
81 using any hash function configured in the [hash] section. At
82 least, the mandatory must be configured.
84 Rewrote the HMAC interface in lib/silccrypt/silchmac.[ch].
86 * Added HMAC list to the SKE proposal list. It has now both
87 hash algorithm list and HMAC list. This makes the protocol
88 incompatible with previous versions. The SKE now seems to work
89 the way it is supposed to work, for the first time actually.
91 * Defined plain Hash algorithms to the protocol specification.
94 Tue Mar 6 15:36:11 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
96 * Implemented support for key agreement packets into the server.
97 Added functions silc_server_key_agreement and
98 silc_server_send_key_agreement. Other than these functions,
99 server has nothing to do with this packet.
101 * Added support for private message key packets into the server.
102 Added functions silc_server_private_message_key and
103 silc_server_send_private_message_key.
107 * Changed the silc_[client|server]_protocol_ke_set_keys to be
108 called in the protocol's final callback instead in the END
109 protocol state. This makes a little more sense and in the same
110 time in client we can use the same protocol routines for normal
111 key exchange and to key agreement packet handling as well.
113 * Added to both client's and server's KE protocol context the
114 SilcSKEKeyMaterial pointer to save the key material. We will
115 bring the key material to the protocol's final callback by doing
116 this. The final callback must free the key material.
118 * Added SKE's packet_send callback into client's KE protocol
119 context so that the caller can choose what packet sending function
120 is used. This way we can use different packet sending when
121 doing normal SKE when doing key agreement packet handling (in
122 the key agreement packet handling we do not want to encrypt
125 * Implemented the responder side of the key agreement routines
126 in the client. The client can now bind to specified port and
127 accept incoming key negotiation. The key material is passed
128 to the application after the protocol is over.
130 * Implemented the processing of incoming Key Agreement packet
131 in the client. Added function silc_client_key_agreement to
134 * Implemented the intiator side of the key agreement routines
135 in the client. The client can now initiate key agreement with
136 another remote client. The key material is passed to the
137 application after the protocol is over.
139 * Created client_keyagr.c to include all the key agreement
142 * Added macro SILC_TASK_CALLBACK_GLOBAL which is equal to the
143 SILC_TASK_CALLBACK except that it is not static.
145 * Created client_notify.c and moved the Notify packet handling
146 from the client.[ch] into that file.
148 * Created client_prvmsg.c and moved all private message and
149 private message key routines from the client.[ch] into that file.
151 * Create client_channel.c and moved all channel message and
152 channel private key routines from the client.[ch] into that file.
154 * Changed silc_client_get_client_by_id_resolve to resolve with
155 WHOIS command instead of IDENTIFY command, in the file
156 lib/silclient/idlist.c.
158 Mon Mar 5 18:39:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
160 * Implemented the SKE's responder side to the Client library.
162 * When FAILURE is received to the protocol do not trust it
163 blindly. Register a timeout to wait whether the remote closes
164 the connection as it should do it, only after that process the
165 actual failure. This was changed to both client and server.
167 * Added client_internal.h to include some of the structures
168 there instead of client.h in lib/silcclient/.
170 * Added function silc_task_unregister_by_callback to unregister
171 timeouts by the callback function.
173 Sat Mar 3 19:15:43 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
175 * Some "Incomplete WHOIS info" errors has been appearing on the
176 log files. Took away the entry->userinfo check from WHOIS
177 reply sending. The entry->userinfo is now " " if client did not
178 provide one. I thought this was fixed earlier but something
179 is wrong still. Let's see if the error still appears.
181 Wed Feb 28 20:56:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
183 * Fixed a minor bug in the login when the channel key is
184 re-generated in the server. It used to generate the key in
185 wrong order and thus caused problems in the channel traffic.
187 * Fixed a minor bug in channel key distsribution after
188 KICK command. The key was not sent to the router even though
191 Tue Feb 27 20:24:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
193 * Added silc_ske_process_key_material_data as generic routine
194 to process any key material as the SILC protocol dictates. The
195 function is used by the actual SKE library but can be used by
196 applications as well. This relates to the private message keys
197 and the channel private keys since they must be processed the
198 same way the normal SILC session keys. The protocol dictates
199 this. Affected files: lib/silcske/silcske.[ch].
201 Added also silc_ske_free_key_material to free the
202 SilcSKEKeyMaterial structure.
204 * Defined silc_cipher_set_key function to set the key for
205 cipher without using the object's method function. The affected
206 files: lib/silccrypt/silccipher.[ch].
208 * Implemented silc silc_client_add_private_message_key,
209 silc_client_add_private_message_key_ske,
210 silc_client_del_private_message_key,
211 silc_client_list_private_message_keys and
212 silc_client_free_private_message_keys functions in the
215 Added functions silc_client_send_private_message_key to send
216 the Private Message Key payload and silc_client_private_message_key
217 to handle incoming Private Message Key payload.
219 * Added Cipher field to the Private Message Key payload to set
220 the cipher to be used. If ignored, the default cipher defined
221 in the SILC protocol (aes-256-cbc) is used.
223 Tue Feb 27 13:30:52 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
225 * Removed lib/silcclient/ops.h file.
227 Redefined parts of the SILC Client Library API. Created new
228 file silcapi.h that deprecates the ops.h file and defines the
229 published Client Library API. Defined also private message key
230 API and channel private key API into the file.
232 This is the file that the application must include from the
233 SILC Client Library. Other files need not be included by
234 the application anymore.
236 * Added new key_agreement client operation callback and also
237 defined the Key Agreement library API for the application.
239 Tue Feb 27 11:28:31 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
241 * Added new packet type: SILC_PACKET_KEY_AGREEMENT. This packet
242 is used by clients to request key negotiation between another
243 client in the SILC network. If the negotiation is started it
244 is performed using the SKE protocol. The result of the
245 negotiation, the secret key material, can be used for example
246 as private message key.
248 Implemented the Key Agreement payload into the files
249 lib/silccore/silauth.[ch].
251 Mon Feb 26 12:13:58 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
253 * Redefined ciphers for the SILC protocol. Added some new ciphers
254 and defined the key lengths for the algorithms. Changed the
255 code accordingly. The default key length is now 256 bits.
257 * Fixed SKE key distribution function silc_ske_process_key_material
258 when the key length is more than 128 bits. The default key
259 length in SILC is now 256 bits.
261 * Added new command status type: SILC_STATUS_ERR_UNKOWN_ALGORITHM
262 to indicate unsupported algorithm.
264 * Renamed rijndael.c to aes.c and all functions as well.
266 * Fixed a long standing channel key setting bug in client library.
267 Weird that it has never surfaced before.
269 * Fixed bug in channel deletion. If the entire channel is removed
270 then it must also delete the references of the channel entry
271 from the client's channel list as the client's channel entry and
272 the channel's client entry share same memory.
274 Sun Feb 25 20:47:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
276 * Implemented CONNECT and SHUTDOWN commands in the client.
278 * Implemented CLOSE command to the client.
280 * Added the function silc_idlist_find_server_by_name into the
281 files silcd/idlist.[ch].
283 Added the function silc_idlist_find_server_by_conn into the
284 files silcd/idlist.[ch].
286 Sat Feb 24 23:45:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
288 * DIE command was renamed to SHUTDOWN. Updated the both code
291 * Defined SILC_UMODE_NONE, SILC_UMODE_SERVER_OPERATOR and
292 SILC_UMODE_ROUTER_OPERATOR modes into lib/silccore/silcmode.h.
294 * Implemented CONNECT, CLOSE and SHUTDOWN commands to the server
297 * Added function silc_server_create_connection function to create
298 connection to remote router. My server implementation actually
299 does not allow router to connect to normal server (it expects
300 that normal server always initiates the connection to the router)
301 so the CONNECT command is only good for connecting to another
304 Sat Feb 24 16:03:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
306 * Added SILC_NOTIFY_TYPE_KICKED to indicate that the client
307 or some other client was kicked from the channel.
309 Implemented the handling of the notify type to both client
312 Implemented silc_server_send_notify_kicked to send the KICKED
313 notify. It is used to send it to the server's primary router.
315 * Implemented the KICK command into server and client.
317 * Added `query' argument to the silc_idlist_get_client function
318 to indicate whether to query the client from server or not if
321 * Added new command status type SILC_STATUS_ERR_NO_CHANNEL_FOPRIV
322 to indicate that the client is not channel founder.
326 Sat Feb 24 00:00:55 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
328 * Removed the rng context from SilcPacketContext structure and
329 changed that the packet routine uses the Global RNG API.
331 Fri Feb 23 11:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
333 * Added support for quit message that client can "leave" on the
334 channel when it quits the SILC. It is ditributed inside the
335 SILC_NOTIFY_TYPE_SIGNOFF notify type.
337 Added silc_server_free_client_data that will take the
338 signoff message as argument.
340 * Changed SKE routines to use the silc_pkcs_sign/verify routines.
342 Thu Feb 22 23:05:36 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
344 * Updated parts of the protocol specification to keep it up
347 Thu Feb 22 15:08:20 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
349 * Added List flag (SILC_PACKET_FLAG_LIST) to indicate list of
350 payloads in one packet.
352 * Deprecated following packet types: NEW_ID_LIST, NEW_CHANNEL_LIST,
353 NEW_CHANNEL_USER_LIST, SET_MODE and SET_MODE_LIST. List packets
354 use now the new List flag.
356 * Also deprecated the following packet types: REPLACE_ID,
357 NEW_CHANNEL_USER and REMOVE_CHANNEL_USER packet types.
359 * Added list support for Notify packet in server.
361 * Added silc_server_send_notify_channel_change to send the
362 CHANNEL_CHANGE notify type to replace channel ID's. Deprecates
363 the silc_server_send_replace_id.
365 * Added silc_server_send_notify_nick_change to send the
366 NICK_CHANGE notify type. Deprecates the function
367 silc_server_send_replace_id.
369 * Added silc_server_send_notify_join to send the JOIN notify type.
370 Deprecates the function silc_server_send_new_channel_user.
372 * Added silc_server_send_notify_leave to send LEAVE notify type.
373 Deprecates the function silc_server_send_remove_channel_user.
375 * Added silc_server_send_notify_cmode and
376 silc_server_send_notify_cumode to send CMODE and CUMODE notify
377 types. Deprecates the silc_server_send_set_mode function.
379 * Added SERVER_SIGNOFF notify type to indicate that server has
380 quit. This means that all clients on the channel from that
381 server will drop. This can be also used when netsplit happens.
383 Deprecated REMOVE_ID packet type since it is not needed anymore
386 Added silc_server_send_notify_server_signoff to send the
387 SERVER_SIGNOFF notify type. Deprecates the function
388 silc_server_send_remove_id.
390 Added also silc_server_send_notify_signoff to send the
393 * Employed the PKCS #1. It is the mandatory way to do RSA in the
394 SILC protocol from this day on. Changed the protocol
395 specification as well.
397 * Added silc_server_send_notify_topic_set to send TOPIC_SET
398 notify type. It is used between routers to notify about
399 topic changes on a channel.
401 * Added silc_id_dup into lib/silccore/id.[ch] to duplicate
404 * Partly updated the protocol specification to comply with the
405 changes now made. It is still though a bit outdated.
407 * The JOIN notify type now takes one extra argument <Channel ID>.
408 The packet used to be destined to the channel but now the
409 JOIN type may be sent as list thus it is impossible to
410 destine it to any specific channel. By adding this argument
411 it is again possible.
413 Wed Feb 21 22:39:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
415 * Added CREDITS file. The CHANGES and CREDITS file will appear
416 in the distribution as well.
418 Wed Feb 21 14:17:04 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
420 * Implemented CMODE_CHANGE, CUMODE_CHANGE and TOPIC_SET notify
421 types in the server's silcd/packet_receive.c.
423 * Implemented CMODE and CUMODE to work in router environment.
425 * Fixed minor encoding and decoding buglet from the
426 lib/silccore/silcmode.c.
428 * Fixed buffer overflow from lib/silcclient/command.c in USERS
431 Wed Feb 21 12:44:00 EET 2001 Mika Boström <bostik@lut.fi>
433 * Changed all SilcConfigServer* and silc_config_server* to
434 SilcServerConfig* and silc_server_config*, respectively.
437 Wed Feb 21 00:10:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
439 * Associated the ID (client or server ID) to the Authentication
440 Payload to avoid any possibility of forging. Updated the
441 protocol specification and the code accordingly.
443 Tue Feb 20 14:14:14 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
445 * The RSA key length is now save to the RsaKey context in the
446 key generation process in lib/silccrypt/rsa.c. The key length
447 is now used to figure out the maximum size of the block allowed
448 to be encrypted/signed.
450 * Added silc_mp_mp2bin_noalloc into lib/silcmath/mpbin.[ch]. It
451 is equivalent to the silc_mp_mp2bin but does not allocate any
454 * Changed silc_mp_mp2bin API to take length argument. If it is
455 non-zero then the buffer is allocated that large. If zero, then
456 the size is approximated using silc_mp_sizeinbase, which however
459 * Created Global RNG API which is global RNG that application can
460 initialize. After initializing, any routine anywhere in the
461 code (including library) can use RNG without allocating a new
462 RNG object. This was done to allow this sort of use of the
463 RNG in code that has no chance to allocate RNG object. All
464 applications currently allocate this and many routines in the
465 library use this. Affected file lib/silccrypt/silcrng.[ch].
467 * Removed the RNG kludge from lib/silcmath/primegen.c and changed
468 it to use the Global RNG API.
470 * Defined Authentication Payload into protocol specification that
471 is used during SILC session to authenticate entities. It is
472 used for example by client to authenticate itself to the server
473 to obtain server operator privileges.
475 Implemented this payload into the lib/silccore/silcauth.[ch].
476 Implemented also routines for public key based authentication
477 as the new protocol specification dictates.
479 Moved definitions of different authentication methods from
480 lib/silccore/silcprotocol.h into lib/silccore/silcauth.h.
482 * Added silc_pkcs_encrypt, silc_pkcs_decrypt, silc_pkcs_sign,
483 silc_pkcs_verify and silc_pkcs_sign_with_hash and
484 silc_pkcs_verify_with_hash functions into the file
485 lib/silccrypt/silcpkcs.[ch].
487 Mon Feb 19 19:59:28 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
489 * The client entry's userinfo pointer must be always valid.
490 Otherwise the [<unknown>] bug will surface beacuse the WHOIS
491 will fail since it requires the userinfo. Now, the userinfo
492 is allocated as "" if actual userinfo does not exist. Actually,
493 it must exist and it is totally Ok to drop client connections
494 that does not announce the userinfo. However, we will make
495 this workaround for now.
497 * Added silc_net_get_remote_port into lib/silcutil/silcnet.[ch]
498 to return the remote port by socket.
500 Mon Feb 19 14:26:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
502 * Changed SILC_SERVER_COMMAND_EXEC_PENDING macro to the name
503 SILC_SERVER_PENDING_EXEC and added an new macro
504 SILC_SERVER_PENDING_DESTRUCTOR which is called to free the
505 data or when error occurs while processing the pending command.
507 Added new argument `destructor' into silc_server_command_pending
508 and to the SilcServerCommandPending object. This destructor is
509 now called after calling the pending callback or if error occurs
510 immediately. If error occurs the actual pending callback won't
511 be called at all - only the destructor. The destructor may be
512 NULL if destructor is not needed.
514 All this applies for client library code as well. Similar
515 changes were made there as well for the pending commands.
517 In the client, the application must now allocate the
518 SilcClientCommandContext with the silc_client_command_alloc
521 * Added reference counter to the SilcServerCommandContext. Added
522 function silc_server_command_alloc and silc_server_command_dup
525 Same type of functions added to the client library for the same
528 * Removed the cmd_ident from IDListData away since it is now
529 global for all connections. It is the command identifier used
530 in command sending and with pending commands. The affected file
533 * Added reference counter to the SilcSocketConnection objecet to
534 indicate the usage count of the object. The object won't be
535 freed untill the reference counter hits zero. Currently only
536 server uses this, and client ignores it. The client must be
537 set to use this too later. The affected files are
538 lib/silccore/silcsockconn.[ch]. Added also the function
539 silc_socket_dup to increase the reference counter.
541 This was mainly added because it is possible that the socket
542 is removed underneath of pending command or other async
543 operation. Now it won't be free'd and proper DISCONNECTING
544 flags, etc. can be set to avoid sending data to connection that
545 is not valid anymore.
547 * Added SILC_SET_DISCONNECTING to server.c when EOF is read from
548 the connection. After that it sets SILC_SET_DISCONNECTED.
549 It is, however, possible that the socket data is not still freed.
550 The silc_server_packet_process now checks that data is not
551 read or written to connection that is DISCONNECTED. The socket
552 get's freed when the reference counter hits zero.
554 Mon Feb 19 00:50:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
556 * Changed the client operation API: channel_message operation's
557 `sender' is now the client entry of the sender, not the nickname
558 and the `channel' is the channel entry, not the channel name.
560 In the private_message operation the `sender' is now also the
561 client entry of the sender not the nickname.
563 Affected file is lib/silcclient/ops.h and all applications
564 using the client operations.
566 Sat Feb 17 22:11:50 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
568 * Moved the calling of ops->connect() from connect_to_server_final
569 into receive_new_id functin since that is the point when the
570 client is actually allowed to send traffic to network. The
571 affected file is lib/silcclient/client.c.
573 Sat Feb 17 13:15:35 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
575 * When receiving NEW_CHANNEL_LIST, NEW_CHANNEL_USER_LIST,
576 NEW_ID_LIST and SET_MODE_LIST packets, broadcast the list packet
577 (if needs broadcasting) instead of broadcasting the packets one
578 by one which would make a burst in the network traffic.
580 * Added `broadcast' argument to the functions in silcd/server.[ch]
581 silc_server_create_new_channel[_with_id] to indicate whether
582 to send New Channel packet to primary router.
584 Sat Feb 17 01:06:44 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
586 * Added new function into the silcd/server.[ch] files:
587 silc_server_create_new_channel_with_id to create new channel with
588 already existing Channel ID.
590 * Added new packet type SILC_PACKET_SET_MODE_LIST into the file
591 lib/silccore/silcpacket.h. This packet is used t send list of
592 Set Mode payloads inside one packet. Server uses this to set
593 the modes for the channels and clients on those channels, that it
594 announced to the router when it connected to it. The protocol
595 specification has been updated accordingly.
597 * The silc_server_new_channel did not handle the packet coming
598 from normal server as it normally does not send that. However,
599 when it announces its channels it does send it. Implemented
600 the support for that.
602 * Added SILC_ID_CHANNEL_COMPARE macro to compare to Channel ID's
603 into the file lib/silccore/id.h.
605 Fri Feb 16 23:57:29 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
607 * Fixed memory leaks in the functions silc_idlist_del_client,
608 silc_idlist_del_channel and silc_idlist_del_server in the file
609 silcd/idlist.c. All of those leaked like a sieve.
611 * Fixed some small memory leaks in the client's function
612 silc_client_notify_by_server.
614 * Added functions into silcd/server.c: silc_server_announce_clients,
615 silc_server_announce_channels and silc_server_announce_server.
616 These functions are used by normal and router server to announce
617 to its primary router about clients, channels and servers (when
618 router) that we own. This is done after we've connected to the
621 These functions effectively implements the following packet types:
622 SILC_PACKET_NEW_CHANNEL_LIST, SILC_PACKET_NEW_CHANNEL_USER_LIST
623 and SILC_PACKET_NEW_ID_LIST.
625 * Added new functions into the silcd/packet_receive.[ch]:
626 silc_server_new_id_list, silc_server_new_channel_list and
627 silc_server_new_channel_user_list to handle the incoming
628 NEW_ID_LIST, NEW_CHANNEL_LIST and NEW_CHANNEL_USER_LIST packets.
630 * Added support of changing Channel ID in the function
631 silc_server_replace_id. If the server that announces a channel
632 to the router already exists in the router (with same name but
633 with different Channel ID), router is responsible to send
634 Replace ID packet to the server and force the server to change
635 the Channel ID to the one router has.
637 * Added new notify type SILC_NOTIFY_TYPE_CHANNEL_CHANGE to notify
638 client that the Channel ID has been changed by the router. The
639 normal server sends this to the client. Client must start using
640 the new Channel ID as the channel's ID.
642 Implemented handling of this new type into lib/silcclient/client.c
643 into the function silc_client_notify_by_server.
645 * Added new function silc_idlist_replace_channel_id into the files
646 silcd/idlist.[ch] to replace the Channel ID.
648 Fri Feb 16 14:14:00 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
650 * Call silc_server_command_identify_check always when processing
651 the IDENTIFY command in silcd/command.c
653 Thu Feb 15 20:07:37 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
655 * Added new packet type SILC_PACKET_HEARTBEAT that is used to
656 send keepalive packets. The packet can be sent by clients,
659 Added function silc_socket_set_heartbeat into the file
660 lib/silccore/silcsockconn.[ch] to set the heartbeat timeout.
661 If not set, the heartbeat is not performed. The actual
662 heartbeat is implemented in the low level socket connection
663 library. However, application is responsible of actually
666 Added silc_server_send_heartbeat to send the actual heartbeat
667 packet into silcd/packet_send.[ch]. Server now performs
668 keepalive with all connections.
670 * Added silc_task_get_first function into lib/silcutil/silctask.c
671 to return the timeout task with shortest timeout. There was a bug
672 in task unregistration that caused problems. TODO has been
673 updated to include that task system must be rewritten.
675 * The client library will now resolve the client information when
676 receiving JOIN notify from server for client that we know but
677 have incomplete information.
679 * Rewrote parts of silc_server_remove_from_channels and
680 silc_server_remove_from_one_channel as they did not remove the
681 channel in some circumstances even though they should've.
683 * Encryption problem encountered in server:
685 The LEAVE command used to send the Channel Key packet to the
686 router immediately after generating it. However, the code
687 had earlier sent Remove Channel user packet but not immediately,
688 ie. it was put to queue. The order of packets in the router
689 was that Channel Key packet was first and Remove Channel User
690 packet was second, even though they were encrypted in the
691 reverse order. For this reason, MAC check failed. Now, this
692 is fixed by not sending the Channel Key packet immediately but
693 putting it to queue. However, this is more fundamental problem:
694 packets that are in queue should actually not be encrypted
695 because packets that are sent immediately gets encrypted
696 actually with wrong IV (and thus MAC check fails). So, packets
697 that are in queue should be encrypted when they are sent to
698 the wire and not when they put to the queue.
700 However, the problem is that the current system has not been
701 designed to work that way. Instead, the packet is encrypted
702 as soon as possible and left to the queue. The queue is then
703 just purged into wire. There won't be any fixes for this
704 any time soon. So, the current semantic for packet sending
707 o If you send packet to remote host and do not force the send
708 (the packet will be in queue) then all subsequent packets to the
709 same remote host must also be put to the queue. Only after the
710 queue has been purged is it safe again to force the packet
713 o If you send all packets immediately then it safe to send
714 any of subsequent packets through the queue, however, after
715 the first packet is put to queue then any subsequent packets
716 must also be put to the queue.
718 Follow these rules and everything works fine.
720 Thu Feb 15 14:24:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
722 * Added new function silc_server_remove_clients_by_server to
723 remove all client entries from ID list when the server connection
724 is lost. In this case it is also important to invalidate all
725 client entires as they hold the invalid server entry. This
726 fixes fatal bug when server has lost connection and will reconnect
729 Wed Feb 14 16:03:25 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
731 * Made some sanity checks to silc_server_daemonise like to check
732 whether the requested user and group actually exists.
734 * Added sanity check to SKE's silc_ske_responder_finish to check
735 that the public and private key actually is valid.
737 * Invalidate the client's nickname when receiving Replace ID
738 packet and the Client ID is being replaced. This means that the
739 server will query the nickname if someone needs it (client)
742 * Sort the ID Cache in client library when the ID Cache data
743 has changed (needs sorting).
745 * Do not allow for SILC client to create several connections to
746 several servers. The client does not support windows right now
747 and generating multiple connections causes weird behaviour.
749 Irssi-silc client does support windows and can handle several
750 connections without problems, see: www.irssi.org and SILC plugin.
752 * Fixed some places where client was added to the IDList. The
753 rule of thumb is following (in order to get everything right):
754 If the client is directly connected local client then the
755 `connection' argument must be set and `router' argument must be
756 NULL to silc_idlist_add_client function. If the client is not
757 directly connected client then the `router' argument must
758 bet set and the `connection' argument must be NULL to the
759 silc_idlist_add_client function.
761 * The funtion silc_server_packet_send_local_channel actually did
762 not check whether the client was locally connected or not. It
763 does that now. Fixed a bug related to LEAVE command.
765 * Fixed Remove Channel User payload parsing bug in server's
766 silcd/packet_receive.c. Fixed a bug related to LEAVE command.
768 * The server's silc_server_save_channel_key now checks also the
769 global ID list for the channel as it might not be in the local
770 list. Fixed a bug related to LEAVE command.
772 * Is this the end of the [<unknown>] buglet that has been lurking
773 around for a long time? A little for loop fix in server's
774 silc_server_command_whois_parse that is used by both IDENTIFY
775 and WHOIS command. At least, this was a clear bug and a cause
776 of one type of [<unknown>] buglet.
778 * WHOIS and IDENTIFY commands call the function
779 silc_server_command_[whois/identify]_check function even if
780 we are not router server.
782 Tue Feb 13 19:55:59 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
784 * Added --with-gmp configuration option. If set the GMP
785 is always compiled in the SILC source tree. If not set then
786 it is checked whether the system has the GMP3 installed. If
787 it has then the GMP won't be compiled (the system's headers
788 and library is used), if it doesn't have it then the GMP is
789 compiled in the SILC source tree.
791 Mon Feb 12 11:20:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
793 * Changed RSA private exponent generation to what PKCS #1
794 suggests. We try to find the smallest possible d by doing
795 modinv(e, lcm(phi)) instead of modinv(e, phi). Note: this is
796 not security fix but optimization.
798 Sun Feb 11 18:19:51 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
800 * Added new config entry [Identity] to fork the server and run
801 it as specific user and group. A patch from Bostik.
803 * Imported Dotconf configuration library into lib/dotconf.
804 This will be used to create the SILC configuration files later.
805 It will appear in the distsribution after this commit.
807 Sat Feb 10 21:13:45 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
809 * A big code auditing weekend happening. Auditing code for
810 obvious mistakes, bugs and errors. Also, removing any code
813 Removed files for being obsolete:
815 o lib/silcutil/silcbuffer.c (the buffer interface is entirely in
816 inline in the file lib/silcutil/silcbuffer.h)
818 o lib/silcutil/silcbufutil.c (the header has inline versions)
820 Changed code to fix possible error conditions:
822 o The buffer formatting routines now check that the destination
823 buffer really has enough space to add the data. This applies for
824 both buffer formatting and unformatting
825 (lib/silcutil/silcbuffmt.[ch]). Also, the entire buffer
826 unformatting was changed to accomodate following rules:
827 XXX_*STRING_ALLOC will allocate space for the data into the pointer
828 sent to the function while XXX_*STRING will not allocate or copy
829 the data into the buffer. Instead it sets the pointer from the
830 buffer into the pointer sent as argument (XXX_*STRING used to
831 require that the pointer must be allocated already). This change
832 makes this whole thing a bit more consistent and more optimized
833 (note that the data returned in the unformatting with XXX_*STRING
834 must not be freed now). The routines return now -1 on error.
836 o Tried to find all code that use buffer_format and buffer_unformat
837 and added return value checking to prevent formatting and
838 especially unformatting errors and possible subsequent fatal
841 o Changed ske->x and ske->KEY to mallocated pointers in
842 lib/silcske/silcske.h. Fixed possible data and memory leak.
844 o Added return value checking to all *_parse* functions. Fixed
845 many memory leaks as well.
847 o Added length argument to silc_id_str2id in lib/silccore/id.[ch]
848 so that buffer overflows would not happen. All code now also
849 checks the return value as it can fail.
851 Mon Feb 5 20:08:30 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
853 * Added reconnection support to server if the normal server looses
854 its connection to the router (for example if router is rebooted).
855 The server performs normal reconnection strategy implemented
856 to the server. Affected file silcd/server.c.
858 Sun Feb 4 13:18:32 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
860 * Added new packet type SILC_PACKET_SET_MODE that is used to
861 distribute the information about changed modes (for clients,
862 channels and clients channel modes) to all routers in the
863 network. Updated the protocol specification accordingly.
865 Added functions into silcd/packet_send.c and
866 silcd/packet_receive.c: silc_server_send_set_mode,
867 silc_server_set_mode.
869 Added new files silcmode.[ch] into lib/silccore that implements
870 the encoding and decoding of Set Mode Payload. Added new type
871 SilcSetModePayload. Moved the definitions of different modes
872 from lib/silccore/silcchannel.h into lib/silccore/silcmode.h.
874 Sat Feb 3 15:44:54 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
876 * Oops, a little mistake in server's connection authentication
877 protocol. The protocol is not ended with FAILURE but with
878 SUCCESS if the authentication is Ok. :) Affected file is
881 * Implemented NICK_CHANGE notify handling in server in the file
882 silcd/packet_receive.c The NICK_CHANGE notify is distributed to
883 the local clients on the channel. After the changing nickname
884 in router environment snhould work and the [<unknown>] nickname
885 should appear no more.
887 The silc_server_replace_id function that receives the Replace ID
888 payload now sends the NICK_CHANGE notify type also in the file
889 silcd/packet_receive.c
891 * Changed WHOIS and IDENTIFY command to support the maximum amount
892 of arguments defined in protocol specs (3328 arguments). This
893 fixed a bug that caused problems when there were more than three
896 Fri Feb 2 11:42:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
898 * Added extra parameter, command identifier, to the
899 silc_client_send_command so that explicit command identifier
902 Changed that ID list routines uses specific command identifier
903 when sending WHOIS/IDENTIFY requests to the server so that they
904 can be identified when the reply comes back.
906 Affected files lib/silcclient/command.[ch],
907 lib/silcclient/client.c and lib/silcclient/idlist.[ch].
909 * Added `sender' argument to silc_server_packet_send_to_channel
910 to indicaet the sender who originally sent the packet to us
911 that we are now re-sending. Ignored if NULL. Affected file
912 silcd/packet_send.[ch].
914 * Added some server statistics support in silcd/server_internal.h
915 SilcServerStatistics structure and around the server code. Also
916 send some nice statistics information when client is connecting
919 Thu Feb 1 23:31:21 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
921 * Fixed channel ID decoding in server's JOIN command reply in
922 silcd/command_reply.c
924 * Fixed braodcasting of replace ID payload to not to send it if
925 we are standalone server in silcd/packet_receive.c.
927 * Fixed all channel message sending routines to not to send
928 packets to clients that has router set, since they are routed
929 separately in the same function earlier. Affects file
930 silcd/packet_send.c and all channel packet sending functions.
932 * In USERS reply, res_argv[i] are not allocated, the table
933 is allocated. Thus changed that free the table, not its
936 * In server's whois_check and identify_check if the client is
937 locally connected do not send any WHOIS commands - they are not
940 Thu Feb 1 21:32:27 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
942 * Fixed some minor bugs in client when sending WHOIS command. The
943 arguments was in wrong order.
945 * Removed statis function add_to_channel from server in
946 silcd/command.c that was previously used with the joining but
949 * Tested USERS command in router environment successfully with two
950 routers, two servers and two clients.
952 Thu Feb 1 00:54:26 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
954 * Reorganized the USERS command and command reply in client library
955 in lib/silcclient/command.c and lib/silcclient/command_reply.c.
956 When the command is given by user we register a pending command
957 callback that will reprocess the command after the reply has been
958 received from the server. When reprocessing the packet we then
959 display the information. Thus, the USERS information is displayed
960 now in the command callback instead of in the command reply
961 callback. The processing of the command is same as previously
962 when server has sent the command reply in the JOINing process.
964 * Added to USERS command in silcd/command_reply.c to join the client,
965 we didn't use to know about, to the channel after we've created
966 a client entry for it. Also, for clienet we did know already still
967 check whether it is on the channel or not and add it if not.
969 * Removed silc_server_command_join_notify as the function and its
972 Tue Jan 30 22:39:15 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
974 * Changed the client's pending command handling to the same as the
975 server's pending command handling. It is also now possible to
976 execute command reply functions from other command reply
977 function as the function callbacks for commands and command
978 replies are one and same. The pending commands are not static
979 list anymore, it is mallocated SilcDList in lib/silcclient/client.h
980 in client connection context. Thus, pending commands are server
981 connection specific as it is convenient.
983 Changed the function silc_client_command_pending and
984 silc_client_command_pending_del and added new function
985 silc_client_command_pending_check. Removed the
986 SILC_CLIENT_CMD_REPLY_EXEC, and SILC_CLIENT_PENDING_COMMAND_CHECK
989 * Added cmd_ident, current command identifier, to the client
990 connection context in lib/silcclient/client.h to keep track on
991 command identifiers used in command sending. Client's command reply
992 function handling now supports the mandatory command identifiers.
994 * Added SILC_CLIENT_COMMAND_EXEC_PENDING macros to all command reply
995 funtions in client to fully support pending command callbacks.
997 * NOTE: the name_list in USERS (old NAMES) command is NOT sent anymore
998 as one of the arguments to the application in the command reply
1001 * NOTE: The FORWARDED flag is depracated. It used to be depracated
1002 before first releasing SILC but came back. Now it is removed again
1003 and should come back nomore. The FORWARDED flag was used only
1004 by the JOINing procedure by forwarding the command packet to router.
1005 Now, the JOINing procedure has been changed to more generic (due
1006 to various router environment issues) and FORWARDED is not needed
1007 anymore for anything. The protocol specification is yet to be
1010 Now, removed silc_server_packet_forward from server and the flag
1011 SILC_PACKET_FORWARDED from lib/silccore/silcpacket.h.
1013 Tue Jan 30 00:05:05 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1015 * Renamed NAMES command to USERS command. The NAMES was named that
1016 due to historical reasons. Now it is renamed. Also, rewrote
1017 parts of the USERS command. The nickname list is not sent anymore
1018 by the server. Only Client ID and mode lists are sent in the USERS
1019 command. Changed this also to the protocol specification.
1021 The client now resolves the names and stuff after it receives
1022 the USERS list from the server when joining to the channel.
1024 * WHOIS and IDENTIFY commands has been changed to support multiple
1025 Client ID's per command. One can now search for multiple users
1026 in the network by sending only one WHOIS or IDENTIFY command.
1027 Changed the code and the protocol specifications.
1029 * Removed silc_server_command_identify_parse and changed that IDENTIFY
1030 uses silc_server_command_whois_parse to parse the request. */
1032 * If normal server, do not parse the WHOIS and IDENTIFY requests
1033 before sending it to the router. Saves some time.
1035 Sun Jan 28 16:19:49 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1037 * Fixed JOIN command on client library. Wrong number of arguments
1038 used to crash the client.
1040 * Added silc_server_channel_has_global function to check whether
1041 channel has global users or not.
1043 * Added silc_server_channel_has_local function to check whether channel
1044 has locally connected clients on the channel.
1046 * The silc_server_remove_from_one_channel now checks whether the
1047 channel has global users or not after given client was removed from
1048 the channel. It also checks whether the channel has local clients
1049 on the channel anymore. If it does not have then the channel entry
1050 is removed as it is not needed anymore.
1052 * The silc_server_notify now checks on JOIN notify whether the joining
1053 client is one of locally connected or global. If it is global then
1054 the channel has now global users on the channel and that is marked
1055 to the channel entry. Also, it now saves the global client to
1056 global list who is joining and JOINs it to the channel. This is
1057 for normal server, that is.
1059 Changed silc_server_send_notify_on_channel,
1060 silc_server_packet_relay_to_channel and
1061 silc_server_packet_send_to_channel check if we are normal server
1062 and client has router set (ie. global client) do not send the
1063 message to that client, as it is already routed to our router.
1065 * Implemented LEAVE notify type handling in silc_server_notify
1068 * Tested LEAVE command in router environment successfully. Tested
1069 with two routers, two servers and two clients.
1073 * idlist_find_xxx_by_id routines now dumps the ID on the debug mode.
1075 * Implemented SIGNOFF notify type handling in silc_server_notify
1078 * silc_server_remove_id now removes the client entry from all channels
1079 it has joined and thusly sends SIGNOFF notify type.
1081 * Rewrote the NAMES list generation in server by removing two excess
1082 loops. The lists are created now inside one loop.
1084 Sat Jan 27 22:34:56 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1086 * silc_server_remove_channel_user checks now also global list
1087 for channel and client.
1089 * silc_server_new_channel_user checks now both local and global
1090 list for channel and client. Fixed a bug in client id decoding.
1091 Used to decode wrong buffer.
1093 * silc_server_channel_message checks now both local and global
1094 list for channel entry.
1096 * Tested channel joining (hence JOIN) in router environment
1097 successfully. Tested with two routers, two servers and two
1100 * Tested channel message sending in router environment successfully.
1102 Thu Jan 11 03:22:57 EET 2001 Pekka Riikonen <priikone@poseidon.pspt.fi>
1104 * Added silc_server_save_channel_key into server.[ch] to save the
1105 received channel key in Channel Key payload processing. It is
1106 also used in JOIN command reply handling.
1108 Equivalent function silc_client_save_channel_key added into
1109 client.[ch] into client library.
1111 * Changed JOIN command reply to send information whether the channel
1112 was created or not (is existing already) and the channel key
1113 payload. Changed protocol specs accordingly.
1115 * Fixed bugs in WHOIS and IDENTIFY command reply sending when
1116 the request was sent by ID and not by nickname. Crashed on
1119 Sat Dec 23 21:55:07 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1121 * Fixed a bug in Client library. IDENTIFY and WHOIS reply functions
1122 now correctly save the received data.
1124 * silc_server_free_sock_user_data now notifies routers in the
1125 network about entities leaving the network.
1127 At the same time implemented functions silc_server_remove_id
1128 and silc_server_send_remove_id to receive and send REMOVE_ID
1129 packets. The packet is used to notify routers in the network
1130 about leaving entities. The ID removed will become invalid in
1133 * Added function silc_idlist_del_server into server. Removes and
1134 free's server entry from ID list.
1136 * silc_server_private_message function now checks, if we are router,
1137 that the destination ID really is valid ID, naturally.
1139 * In router when NEW_ID packet is received (for new client) the
1140 hash of the Client ID is saved in the ID Cache but the
1141 client->nickname is set to NULL, instead of putting the hash
1144 IDENTIFY command now also checks that client->nickname must be
1145 valid. If it is not if will request the data from the server who
1146 owns the client. Added new function
1147 silc_server_command_identify_check.
1149 * Added silc_command_set_command into lib/silccore/silcommand.[ch]
1150 to set the command to already allocated Command Payload.
1152 * Tested private message sending in router environment with two
1153 routers, two servers and two clients. Fixed minor bugs and now
1156 * Fixed segfault from client's NAMES command. Used to crash if
1159 * Forwarded packets must not be routed even if it is not destined
1160 to the receiver. Changed server code comply with this.
1162 Sun Dec 17 14:40:08 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1164 * Added `require_reverse_mapping' boolean value to ServerParams
1165 structure. If TRUE (not default) the server will require that
1166 the connecting host has fully qualified domain name.
1168 If the reverse mapping is not required and hostname could not be
1169 found the IP address is used as hostname.
1171 Sat Dec 16 17:39:54 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1173 * Implemented version string checking to both client and server.
1174 The check is incomplete currently due to the abnormal version
1175 strings used in development version of SILC.
1177 * Changed all command functions in server to use the new
1180 Fri Dec 15 15:55:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1182 * Changed char *data to unsigned char *data in ID Cache system to
1183 support binary data as ID Cache data. Changed code to support
1184 binary data in lib/silccore/idcache.c.
1186 * Renamed silc_server_packet_relay_command_reply to
1187 silc_server_command_reply as it is normal packet receiving
1188 function. Rewrote the function to accept command replys for
1189 servers and not only for clients.
1191 * Mark remote router always as registered server if we are connecting
1192 to it. Otherwise, commands sent by the router to us are ignored.
1194 * All ID List find routines now returns the ID Cache Entry pointer
1195 as well if requested.
1197 * WHOIS command works now in router environment, tested with two
1198 routers, two servers and two clients.
1200 * Cleaned up and rewrote IDENTIFY command. IDENTIFY should work now
1201 in router environment (as it is almost equivalent to WHOIS) but
1202 hasn't been tested thoroughly. Added new functions:
1204 silc_server_command_identify_parse
1205 silc_server_command_identify_send_reply
1206 silc_server_command_identify_from_client
1207 silc_server_command_identify_from_server
1209 * Disabled route cache adding because adding two different ID's with
1210 same IP replaces the old cache entry thus giving wrong route.
1211 The entry->router->connection is always the fastest route anyway
1212 so route cache may not be needed. Of course, new routes maybe
1213 established after receiving the ID when the entry->router->connection
1214 might not be anymore the most optimal.
1216 Thu Dec 14 15:55:35 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1218 * Add route cache for received ID for fast routing.
1220 * Added silc_server_packet_route to route received packet on router
1221 that is not destined to us.
1223 * Renamed silc_server_get_route to silc_server_route_get.
1225 * Added id_string and id_string_len fields into SilcServer to
1226 include encoded ServerID for fast comparing without excess
1227 encoding of the ID's.
1229 * Cleaned up WHOIS command on server side. Added following static
1232 silc_server_command_whois_parse
1233 silc_server_command_whois_check
1234 silc_server_command_whois_send_reply
1235 silc_server_command_whois_from_client
1236 silc_server_command_whois_from_server
1238 * Added macro SILC_SERVER_COMMAND_CHECK_ARGC to check mandatory
1239 arguments in command replies. All command functions should be
1240 updated to use this macro.
1242 Sun Dec 10 23:52:00 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1244 * Minor typo fixes on command reply handling on server.
1246 Tue Nov 28 11:05:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1248 * Added silc_server_command_add_to_channel internal routine to add
1249 the client to the channel after router has created the channel and
1250 sent command reply to the server.
1252 * Added generic silc_server_send_command to send any command from
1255 * Use static buffer with ID rendering instead of duplicating data.
1257 Mon Nov 27 21:39:40 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1259 * Fixed a channel user mode bug when joining to a channel server gave
1260 everybody channel founder rights, oops.
1262 * We mark ourselves as the router of the incoming server connection
1263 if we are router ourselves. This way we can check in some packet
1264 sending functions whether it is locally connected server. For
1265 incoming router connections we put NULL.
1267 * For router sending packets locally means now always sending the
1268 packet cell wide; to local clients and local servers. For normal
1269 server sending packet locally means sending it to only local
1272 * Fixed the JOIN command to really work in router environment. If the
1273 channel is created it is always created by the router. Router is
1274 also responsible of making the initial joining to the channel,
1275 sending JOIN notify to the sending server and distributing
1276 NEW_CHANNEL and NEW_CHANNEL_USER packets. Hence, if the channel
1277 does not exist server doesn't do anything else but forward the
1278 command to the router which performs everything.
1280 * Added silc_server_send_channel_key function to send the Channel Key
1283 * Added silc_server_create_channel_key to create new channel key. The
1284 channel key is now re-generated everytime someone joins or leaves
1285 a channel, as protocol dictates. Note: channel->key_len is the
1288 Wed Nov 22 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1290 * Splitted server.[ch] finally. Created now packet_send.[ch] and
1291 packet_receive.[ch] to separate packet sending and receiving
1292 routines. The server.[ch] now includes everything else including
1293 actual packet processing (writing and reading data) and other
1296 Renamed silc_server_private_message_send_internal to
1297 silc_server_send_private_message. The routine is still though
1298 used only to relay private messages as server does not send
1299 private messages itself.
1301 Renamed silc_server_new_channel to silc_server_create_new_channel
1302 and added new function sicl_server_new_channel that handles the
1303 incoming New Channel packet. Added also new sending function
1304 silc_server_send_new_channel to send New Channel Payload.
1306 * Added new function silc_server_notify to process incoming notify
1307 packet to the server/router. Server may then relay the notify
1308 to clients if needed.
1310 * Added new function silc_server_new_channel_user to process incoming
1311 New Channel User packet. Router will redistribute the packet and
1312 send JOIN notify to its local clients and locally connected servers
1313 if needed. Normal server will send JOIN notify to its local client
1314 on same channel when received this packet. Added also corresponding
1315 sending function silc_server_send_new_channel_user to sent the
1318 * Added boolean route argument to send_notif_to_channel and
1319 packet_send_to_channel functions to attempt to route the packet
1320 if it is TRUE and send only locally if it is FALSE.
1322 Tue Nov 21 19:49:31 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1324 * silc_server_replace_id now broadcasts the received replace ID
1325 packet if it is not broadcast packet already. The router must
1326 broadcast to inform other routers about changed ID.
1328 * Added backpointer to server's router into SilcServer context in
1329 silcd/server_internal.h.
1331 * Fixed silc_server_packet_broadcast to send correct broadcast
1334 * The channel key is now distributed to the local client as soon
1335 as it is received from the router (in router environment) so that
1336 no other packet may be sent for the channel until client has
1339 * silc_server_remove_channel_user now broadcasts the received
1340 Remove Channel User packet if it is not broadcast packet already.
1341 The router must broadcast to inform other routers about removed
1344 * Added users field into SilcPacketContext that is a reference count
1345 of the context. One can increase the reference count by calling
1346 silc_packet_context_dup which is now changed to just increase the
1347 reference count instead of duplicating the data. The reference
1348 count is decresed by calling silc_packet_context_free that will
1349 free the data after the reference count hits zero.
1351 For now on the packet context and everything allocated into it
1352 (including the raw packet from network) must be freed by calling
1353 the new silc_packet_context_free function. Added also new function
1354 silc_packet_context_alloc that must be used now to allocate the
1355 context. This also means that if a routine is asynchronous from
1356 silc_[client/server]_packet_parse_type the packet context must
1357 be duplicated by calling silc_packet_context_dup. Otherwise it
1358 gets free'd after silc_[client/server]_packet_parse_type returns.
1359 Also, one must remember that if packet is duplicated then its
1360 reference count must be decresed by calling the free function as
1361 many times as it was duplicated.
1363 * Changed SilcBuffer field from protocol contexts to SilcPacketContext
1364 from both client and server.
1366 Mon Nov 20 23:47:03 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1368 * Made joining to a channel working in router environment.
1370 * Cleaned up JOIN command on server side and create function
1371 silc_server_command_join_channel internal routine to make the
1374 Thu Nov 9 21:12:39 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1376 * Changed silc_command_pending list to SilcDList. Also, added
1377 `ident' field to SilcServerCommandPending structure to identify
1378 the reply and to call correct callback.
1380 Added silc_server_command_pending_check function to replace the
1381 corresnponding macro. The silc_command_pending list is not
1384 * Added silc_command_set_ident into lib/silccore/silccommand.[ch]
1385 to set identifier to previously allocated Command Payload. It
1386 is used to set identifier for command when resending Command
1389 * Added silc_command_payload_encode_payload to encode Command
1390 Payload buffer from SilcCommandPayload structure.
1392 * Added silc_argument_payload_encode_payload to encode Argument
1393 payload buffer from SilcArgumentPayload structure.
1395 Wed Nov 8 21:03:28 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1397 * Changed WHOIS command to support router connection on server side.
1398 The whois request is always sent to router unless the server is
1399 standalone server. After server has received the reply from the
1400 router will it send the reply to the client.
1402 * Added silc_server_packet_broadcast into silcd/server.[ch] to
1403 broadcast received broadcast packet. The function is used only
1404 by router. The broadcast packet is always sent to the router's
1407 * Added silc_id_render function in lib/silcutil/silcutil.[ch] to
1408 render given ID to printable string, for log files for example.
1410 Tue Nov 7 22:14:19 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1412 * Made basic router to router connections working. At least they
1413 can now connect to each other but nothing really works the way
1414 they are supposed - yet.
1416 * Added new initiator token to RouterConnection configuration
1417 file in silcd/serverconfig.[ch]. It is used to tell whether we
1418 are the initiator to the remote router or whether we'll expect
1419 the other end to connect.
1421 * Moved registering of listener task to silc_server_init, hence
1422 the server starts listenning as soon as it is run, even if it
1423 does not have connections to other routers. Let's see how well
1426 * Changed default connection retry timeouts for more suitable in
1429 * Removed cipher and such arguments from silc_idlist_add_client
1430 and silc_idlist_add_server prototypes from silcd/idlist.[ch].
1431 Added new function silc_idlist_add_data to add the keys and stuff
1434 * Added SilcIDListData structure and added it to SilcClientEntry
1435 and SilcServerEntry as their first field in the structure. This
1436 way we can explicitly cast the ID entries to the SilcIDListData
1437 structure and get common data for the entries. In past, we had
1438 to first check what type of connection it is and then cast it to
1439 correct ID entry type. Now, we can directly cast the opaque
1440 pointer to the SilcIDListData (no matter what ID entry it actually
1441 is) and get the data needed.
1443 Mon Nov 6 21:56:12 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1445 * Wow, found a bug in scheduler. The scheduler uninitialized itself
1446 in some circumstances even if threre were timeout tasks, though not
1447 IO tasks, but tasks anyway. Now fixed.
1449 * Defined SilcServerConnection structure to hold connection specific
1450 stuff about directly connected servers and routers. The definition
1451 is currently in silcd/server_internal.h. I thought about having
1452 a bit more important role fro this struct but for now it is used
1453 only when connecting to other server (or router actually).
1455 * Added connecting retry support in server when connecting to
1456 router(s). The retry feature implement exponential backoff
1457 algorithm. Also, added SilcServerParams structure to hold default
1458 parameters for server. For now, it include these retry settings
1459 and are hard coded. After server is moded to be as Silc Server
1460 Library this structure will be more important.
1462 Sun Nov 5 22:28:44 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1464 * Changed client librarys channel->clients table to SilcList and
1465 changed code accordingly.
1467 Thu Nov 2 16:28:01 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1469 * Changed client's channel table to SilcList and changed code
1470 accordingly. Also changed SilcChannelClientEntry to include back-
1471 pointer to the channel so that client entry can use that structure
1472 as list as well and we have fast cross-reference to the channel.
1473 This change dramatically decreased the complexity of channel
1474 handling with client entry and vice versa (removed one extra
1475 loop when searching for channel entry from many functions).
1477 * Changed server->sim from table to SilcDList and changed code
1480 * NAMES command can now be used from user interface. It will show
1481 the user list on the channel, neatly.
1483 * Added realname pointer to SilcClientEntry in lib/silcclient/idlist.h.
1484 Code now saves realname of the user if it becomes available.
1486 * Renamed configure.in to configure.in.pre and made ./prepare
1487 script to automatically add correct version string to
1488 configure.in which it creates from configure.in.pre.
1490 Wed Nov 1 17:21:26 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1492 * NAMES command reply now shows users mode with the nickname when
1495 * Moved silc_client_ch[u]mode[_char] functions from
1496 silc/clientutil.[ch] to lib/silcclient/client.[ch]. Though, that
1497 place sucks, they are utility functions and should be in some
1500 * Fixed some unsigned int's to unsigned short's. Patch by cras.
1502 * Fixed contrib/getopt*.[ch] to not require config.h. Patch by
1505 Tue Oct 31 20:10:37 EET 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1509 * Added TRQ (efficient deque and list library) into lib/trq. This is
1510 a very good list library that is currently used in the SILC. Defined
1511 SilcList API over the library because I didn't like the API very
1512 much. See lib/trq/silclist.h for the API and examples of how to
1513 use the API. Fixed various places in the code to use the new
1514 SilcList API. The SilcList is meant for lists that has a structure
1515 already defined as a list. It is not suitable to add just some
1516 context to the list (in TRQ, the context is the list actually).
1518 So, I defined SilcDList that can be used for the purpose where
1519 predefined list structure does not exit. This can be used as
1520 such list. Now some context just can be added to the SilcDList.
1521 Currently this list is not used in the SILC just yet, though there
1522 are a lot places where this can replace dynamically allocated
1523 tables and I will fix these places, later, to use SilcDList.
1524 See lib/trq/silcdlist.h for SilcDList (they are all inline functions,
1525 and use TRQ internally).
1527 Also fixed some annoying warning messages that the original TRQ
1528 code generated. Also minor changes to TRQ's Makefile.in.
1530 * Added support for querying by Client ID to both WHOIS and
1531 IDENTIFY commands into server, as required by the protocol.
1533 * Removed method function pointers from SilcBuffer structure. They
1534 weren't used to anything and just increased the context size for
1535 no good reason. This change also made silc_buffer_alloc and
1536 silc_buffer_free functions inline functions.
1538 * Disabled command flooding detection support until it's fixed so
1539 that it accepts commands in but does not execute them more than once
1542 * Added silc_net_localhost(), to return local hostname, into
1543 lib/silcutil/silcnet.[ch]. Also added client->hostname pointer
1544 that must be initialized before calling silc_client_init.
1546 * Added new function: silc_server_send_notify_on_channels to send
1547 notify messages to all channels client has joined. It is assured
1548 that the message is sent only once per client.
1550 * Moved silc_log_format (from lib/silcutil/silclog.[ch] into
1551 lib/silcutil/silcutil.[ch] as silc_format function. The new
1552 function is generic and is used by server as well, not only by
1553 the logging routines.
1555 * Added new SKE status type: SILC_SKE_STATUS_BAD_VERSION to indicate
1556 the provided version string was not acceptable. Added new function:
1557 silc_ske_check_version into lib/silcske/silcske.h. The function
1558 must be implemented by the application (client or server) and it
1559 does not reside in the SKE library. The function checks the version
1560 string remote end sent.
1562 * Added back pointers (to opaque context and to SilcSocketConnection)
1563 into SilcPacketContext structure into lib/silccore/silcpacket.h.
1565 * Added silc_packet_context_dup into lib/silccore/silcpacket.[ch] to
1566 duplicate packet context structure.
1568 * Changed `notify' client operation to send same arguments as client
1569 receives from server except for ID's. ID's are mapped to correct
1570 ID entry and that is returned. Also, if channel entry is not sent
1571 by server but the notify is for channel the channel entry is sent
1572 to application (otherwise application doesn't know that it is for
1573 channel (library gets it from packet's Destination ID)).
1575 * Added silc_client_remove_from_channels into client library to
1576 remove a client from all channels it has joined to. Used when
1577 received SIGNOFF notify from server. Added also new function
1578 silc_client_replace_from_channels to replace old ID entry with
1579 new ID entry on all channels. Used when received NICK_CHANGE
1582 * Fixed ID Cache list handling in silc_idlist_get_client in
1583 lib/silcclient/idlist.c. Also, added silc_idlist_get_client_by_id
1584 to get (or query) client by ID.
1586 * Updated TODO list.
1588 * Added connection authentication status message defined by the
1589 protocol: SILC_CONN_AUTH_OK and SILC_CONN_AUTH_FAILED and added the
1590 support for these into the code in client and server side.
1592 * Added generic function silc_client_send_command to send any command
1593 with variable argument list. Application should use this function
1594 to send commands if the command functions provided by the library
1595 does not suite for the application's user interface needs.
1597 * Added new `failure' client operation. Application is notified about
1598 received failure packet if client is executing a protocol. In this
1599 case the protocol's execution has failed.
1601 * Added SKE's end notify to send the SKE_SUCCESS notify message that
1602 is required by the protocol.
1604 * Added SILC_PROTOCOL_STATE_FAILURE to indicate received failure
1605 packet from remote. SILC_PROTOCOL_STATE_ERROR indicates local
1608 * Added status flag to SilcSKE object to indicate realtime status
1609 of the SKE protocol.
1611 * Application receives now exactly same command reply arguments as
1612 the library receives from server. However, if ID is received the
1613 corresponding ID entry is returned to the application (eg. Client
1614 ID is mapped to correct SilcClientEntry entry and that is returned).
1615 Changed command_reply client operation due to this change.
1617 * Changed all ID's in commands and in command replys as ID Payloads.
1618 Change affected both client and server side codes.
1620 All ID's sent in SILC network (with execption of ID's in SILC
1621 Packet header) are sent in ID Payload to support variable length
1624 * Server now notifies nick changes and notifies all clients on
1625 the channels about the new nickname (about the new Client ID,
1628 * Implemented CMODE command to change channel modes. Supports all
1629 channel modes defined by the protocol specs except ban and invite
1630 lists. (Also, private channel key mode is supported but support for
1631 setting private channel key in client is missing, thus, this mode
1632 has no effect on client side (except that server requires that the
1633 client uses private channel key and normal channel traffic does not
1636 Also, invite mode works per se, but INVITE command does not work
1637 yet correctly, so you can set channel as invite only channel but
1638 inviting clients to the channel does not work (it is yet to be
1639 thought what's the best way to do it).
1641 * Added new command SILC_COMMAND_CUMODE to change user mode on the
1642 channel. Defined user modes: CHANNEL_FOUNDER and CHANNEL_OPERATOR.
1643 Implemented CUMODE command to change user's mode on the channel.
1644 Supports all modes defined by the protocol specs.
1646 * Added NAMES command reply to return users modes on the channel.
1648 * Removed unnecessary and slow ciphers from lib/silccrypt.
1650 * Set SO_KEEPALIVE option to connection sockets by default.
1652 * Added new command reply status: SILC_STATUS_USER_NOT_ON_CHANNEL.
1654 * Added notify types: MOTD, CMODE_CHANGE and CUMODE_CHANGE. Also,
1655 redefined the Notify Payload into protocol specs.
1657 * Added silc_id_payload_parse_id to get ID directly from raw
1660 Mon Oct 9 20:57:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1662 * Changed SILC_COMMAND_IDENTIFY in protocol specification to
1663 accept searching by Client ID as well.
1665 * Added support for LEAVE and SIGNOFF notify types in client library.
1667 * Added silc_id_payload_parse_data into lib/silccore/silcpayload.[ch]
1668 to parse ID Payload from raw data.
1670 Sun Oct 8 19:33:08 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1672 * Added flags parameter into silc_ske_assemble_security_properties
1673 function in lib/silcske/silcske.[ch].
1675 * Changed notify client operation to fit better for notify messages
1676 sent by server. The notify payload received from server is now
1677 passed to the application (after parsing it to SilcNotifyPayload).
1678 It is application's responsibility to retrieve the arguments
1679 from the payload and show the message the way it wants. The message
1680 sent by server is implementation specific.
1682 * Changed public keys to comply with the protocol specification.
1683 Old public keys are not supported anymore and are not compatible.
1685 * Removed nickname from Channel Payload as the latest draft removed
1686 it. The client must resolve the nickname from the NAMES command
1687 reply received when it joined the channel.
1689 Also, changed all channel_xxxx_payload to channel_payload_xxxx.
1691 Sat Oct 7 21:55:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1693 * Fixed some errors in protocol specification drafts.
1695 * Created lib/silccore/silcnotify.c to implement Notify Payload
1696 encoding and decoding, lib/silccore/silcpayload.[ch] to implement
1697 generic payloads described by protocol specifications. The file
1698 includes implementations for ID Payload and Argument Payload.
1700 * Changed Command Payload implementation to use the new Argument
1701 Payload. Changed command_xxxx_payload to command_payload_xxxx
1702 to comply with SILC coding conventions.
1704 * Added suppport for Argument Payload handling in Notify Payload
1705 implementation as protocol requires it. Added the new support
1706 into server and client lib as well.
1708 Thu Oct 5 21:16:28 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1710 * Added support for multiple nicknames on same channel. [n] is
1711 added locally to the nickname if there are more than one same
1712 nicknames on the channel.
1714 * Server now sends all nicknames that matched WHOIS request.
1715 Client also shows the list received from server.
1717 * Added TOPIC command to client side. User can now set and show
1718 current topic on channel.
1720 * Added MOTD command to client and server. Also, server sends the
1721 motd when client connects to the server.
1723 * Changed version strings to comply ISO 8601.
1725 Wed Oct 4 23:29:06 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1727 * Fixed protocol error handling in client library. It should now
1728 cope even if the SKE fails for some reason.
1730 * Made new protocol specification drafts for submitting to IETF.
1732 * Implemented TOPIC command to server in silcd/command.c.
1734 * Added two new notify types into lib/silccore/silcnotify.h:
1735 SILC_NOTIFY_TYPE_NICK_CHANGE and SILC_NOTIFY_TYPE_TOPIC_SET to
1736 notify nickname change and topic setting/change on a channel.
1738 * API change of command_reply operation in client library. The
1739 application gets now the status type received from server as well.
1741 Sat Sep 30 16:57:42 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1743 * Removed the function just added to lib/silcutil/silcschedule.[ch].
1745 * Cras fixed and optimized the packet handling even further and
1746 it should work now. Minor change to the prototype of function
1747 silc_packet_receive_process in lib/silccore/silcpacket.[ch].
1749 Sat Sep 30 08:48:47 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1751 * Added new function into lib/silcutil/silcschedule.[ch]:
1752 silc_schedule_with_fd to select() a specified fd. The function
1753 returns after timeout expires or data arrives or goes. The
1754 function is used by packet routines to wait that all data is
1755 received from network.
1757 * Fixed data reading from network in lib/silccore/silcpacket.c.
1758 The code now assures that all data is read from the fd and then
1759 continues packet processing. This was a bug fix since the code
1760 used to drop some data in some circumstances.
1762 * Added new function into lib/silcclient/client.[ch]:
1763 silc_client_start_key_exchange to start key exchange after
1764 connection has been established to server. The code internally
1765 now uses this funtion but its main purpose was to provide it
1766 for applications that perform their own connecting. After
1767 application has created a connection it merely calls this
1768 function to start the key exchange between client and server.
1769 The library takes care of everything else after that.
1771 Updated also lib/silcclient/README to explain the usage of
1774 * Do not send to application information that connection has
1775 been established. Application gets notified it by connect
1778 Thu Sep 28 23:40:19 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1780 * Applied cras's patch to add silc_schedule_one function. The
1781 function runs scheduler once and returns.
1783 * Fixed the scheduler after cras messed it up. The timeout
1784 handling works now as it's supposed to work.
1786 * Added into lib/silccore/ silcnotify.h to include notify
1787 message types support. Changed silc_server_send_notify*
1788 functions, in server.[ch], to support those new notify types.
1789 Added the support for the notify types into client library,
1790 as well. Added new notify client operation into ops.h in
1793 * Changed silc_server_packet_send_to_channel to send normal
1794 packets instead of just channel message packets. The function
1795 is now used to send the notify packets to channels. It is not
1796 used to send channel message packets anymore, as server never
1799 * Added explicit casting into lib/silcutil/silcbuffmt.c to few
1800 va_arg()s as it seems to require it nowadays. I guess, if SILC
1801 is compiled with older va_arg() the new code should work anyway.
1803 Wed Sep 13 18:10:14 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1805 * Splitted core library. Core library (lib/silccore) includes
1806 now only SILC protocol specific core (and common) components.
1807 Created new utility library (lib/silcutil) that includes more
1808 generic purpose stuff. The stuff for util library was taken
1809 from the old core library. This was minor and easy split.
1811 * Created SILC Client Library (lib/silcclient) that includes
1812 implementation of the SILC client without user interface. This
1813 was major move from silc/ directory. The code has been changed
1814 so that it is transparent towards the user interface. The
1815 silc/ directory includes now the same user interface as before
1816 and it uses the new client library. Read lib/silcclient/README.
1817 Basicly, the client library performs everything else related
1818 to SILC except user interface handling. Also, configuration
1819 files are considered to be part of user interface and library
1820 does not handle them.
1822 This change also changed a lot of structures, function naming etc.
1823 Most important change was that SilcClientWindow object was
1824 renamed to SilcClientConnection in the client library. Created
1825 also new file lib/silcclient/ops.h. Also added new files
1826 silc/local_command.[ch] and silc/client_ops.[ch].
1828 All these changes were made to make it easier for user interface
1829 designers to create what ever user interface for the SILC client
1832 It is also expected that the server will be moved to lib
1833 directory as well and SILC Server Library will be created;
1834 sometimes in the future.
1836 * Removed Local commands from lib/silccore/silccommand.h as
1837 they are application specific and new client library does not
1838 handle any of those anymore.
1840 * Several functions moved to lib/silcutil/silcutilc.[ch] from
1841 old client implementation in silc/.
1843 * Added support for callback functions in SILC_LOG_* macros.
1844 Application can now set its own callbacks that will be called
1845 instead of using the default functions that will always print
1846 the debug messages to stderr (or stdout). Also, debugging can
1847 now be disabled by setting silc_debug to FALSE and re-enabled by
1848 setting it to TRUE. Note, that logging will still work even
1849 if debugging is disabled.
1851 New functions in lib/silcutil/silclog.[ch]: silc_log_set_callbacks,
1852 silc_log_reset_callbacks, silc_log_set_debug_callbacks and
1853 silc_log_reset_debug_callbacks.
1855 * To enable debugging in silc client one must give now -d
1856 option on command line.
1858 * Changed silc_schedule_init to automatically allocate task queues
1859 if they are not allocated before calling it.
1861 Thu Sep 7 10:49:33 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1863 * Added GMP 3.1 into math library.
1865 Sun Aug 20 21:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1867 * Added SILC_PACKET_REMOVE_CHANNEL_USER to remove a client from
1868 a channel in SILC network. The packet is used by servers and
1869 routers to notify other routers that user has left a channel.
1870 This little feature was missing until now. Added the feature
1871 to protocol specification as well.
1873 Added functions: silc_server_send_remove_channel_user and
1874 silc_server_remove_channel_user into server.[ch].
1876 * Added SILC_PACKET_REKEY and SILC_PACKET_REKEY_DONE into
1877 lib/silccore/silcpacket.h. However, they are not implemented
1880 Sat Aug 19 23:04:16 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1882 * Fixed joining to a channel and sending channel messages
1883 between server and router. The channel message sending should
1884 now work inside a cell.
1886 Tue Jul 25 20:46:13 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1888 * Fixed the private message sending between server and router.
1889 The private message sending should now work inside a cell.
1891 * Added silc_server_replace_id into server.[ch] to replace
1892 existing ID in the SILC network.
1894 * Added silc_idlist_find_server_by, silc_idlist_replace_client_id
1895 and silc_idlist_replace_server_id into idlist.[ch] in server.
1897 Mon Jul 24 18:33:31 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1899 * Fixed the server to server connections. Server can again now
1900 connect to router. Router to router connections probably does
1903 Thu Jul 20 13:15:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1905 * Added dynamic protocol registering support. Now protocols can
1906 registered and unregistered on the fly. Patch by cras.
1908 Wed Jul 19 19:08:46 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1910 * Added lib/contrib directory to hold routines that some platforms
1911 don't have but are needed by SILC.
1913 * Added getopt.c, getopt1.c and getopt.h from GNU C library
1914 into lin/contrib to provide getopt() and getopt_long() for
1915 those who don't have it.
1917 Tue Jul 18 20:41:20 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1919 * Added AWAY command to client. When away message is set and
1920 client receives a private message packet the client automatically
1921 replies to the sender with the away message.
1923 * Fixed a bug in lib/silcmath/mpbin.c: silc_mp_mp2bin. This
1924 bug seemed to be the cause of recent problems when compiling
1927 * Added version detection support to SKE protocol specification
1928 and added the new changes to the SKE implementation as well.
1929 There were other minor changes in the SKE protocol as well.
1931 Many changes in lib/silcske/silcske.[ch] and in
1932 lib/silcske/payload.[ch].
1934 * Added ^U functionality, clear input line. Patch from cras.
1936 Mon Jul 17 23:33:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1938 * Mainly small bugfixes on core library. Fixed some debugging
1939 logging and buffer overflow in silclog.c.
1941 * Updated config.sub and config.guess on the distribution tree.
1943 Sat Jul 15 15:33:48 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1945 * Added command lagging support in server. Client may execute
1946 commands now only once in two seconds.
1948 Thu Jul 13 22:10:21 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1950 * Optimized packet reception. MAC computation and checking is now
1951 also more optimized. A lot previously duplicated code is now
1952 used as generic by both client and server.
1954 * Fixed key pair generation in clientutil.c
1956 Wed Jul 12 18:28:07 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1958 * Added into lib/silccore/silcbufutil.[ch] new function;
1959 silc_buffer_realloc.
1961 * Moved generic packet sending/encryption functions to
1962 lib/silccore/silcpacket.[ch] from client and server. Some
1963 rewriting of the functions.
1965 * Moved all generic packet reception/decryption functions to
1966 lib/silccore/silcpacket.[ch] from client and server. The
1967 packet processing is now much cleaner in both client and server.
1968 These were major changes in both client and server.
1970 * Created many common functions in server to do packet sending.
1971 Previously code were duplicated a lot, this has been removed
1974 Tue Jul 11 20:27:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1976 * Rewrote major parts of the ID cache system. Don't know
1977 whether it is better now or not but at least the API is more
1980 * Major rewrite on ID cache stuff on client because of the ID
1981 cache API changes. Added idlist.c to client.
1983 * Also major rewrite on ID cache stuff on server as well.
1984 Major rewrite of idlist.[ch]. SilcXXXList's are now named
1985 SilcXXXEntry's. We won't keep anymore idlist specific pointers
1986 in hand, instead they are all put into the ID cache system now.
1987 All server_idlist_* routines uses ID cache now instead of
1988 traversing its own lists (those lists does not exist anymore).
1989 SilcIDList though still exists. Also, SilcXXXEntry's are
1992 Sun Jul 9 15:19:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
1994 * Finally made the SKE implementation compliant to the protocol
1995 specification. All mp integers are now binary encoded as
1996 opposed being HEX encoded.
1998 * Added lib/silcmath/mpbin.[ch]. Encoding mp intergers to and
2001 * Added into lib/silccore/silcutil.[ch] PEM encoding/decoding
2002 functions: silc_[encode/decode]_pem. Also added function
2003 silc_encode_pem_file to PEM encode with newlines ('\n') for
2006 * SILC public keys are now encoded either PEM or binary. Same
2007 option is for private keys as well. By default private keys
2008 are binary encoded and public keys PEM encoded. Silly HEX
2009 encoding were removed.
2011 * Added into lib/silccrypt/silchash.[ch] silc_hash_fingerprint
2012 function to create fingerprints.
2014 * Fixed a bug in SHA1; does not change the original data anymore.
2016 * Partly implemented INFO command on client and server side.
2017 Fixed CLEAR command. Changes to SERVER command; show current
2018 server(s) when giving command without arguments. Added
2019 VERSION command to client.
2021 * Added check to server that unregistered connections cannot
2022 execute commands (unless it is specificly allowed).
2024 Thu Jul 6 18:12:24 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2026 * Fixed screen refresh.
2028 * Fixed channel joining bug from client. On some circumstances
2029 client tried to join to a channel it had already joined.
2031 * Added public key verification process into client's protocol.c.
2032 The client now verifies the public key from user and saves
2033 it into ~./silc/serverkeys/ directory.
2035 Added into: clientutil.[ch]: silc_client_verify_server_key.
2037 * Changed SKE protocol's silc_ske_initiator_finish function
2038 to accept callback function that verifies the received public
2039 key. Removed old silc_ske_verify_public_key function.
2041 Wed Jul 5 19:19:02 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2043 * Added into silcpkcs[ch]: silc_pkcs_public_key[_data]_set and
2044 silc_pkcs_private_key[_data]_set.
2046 * Made the password and public authentication more cleaner in
2047 server's protocol.c.
2049 * Removed historic and obsolete protocol `channel_auth' from
2050 both client and server.
2052 * Removed wrong way of sending command status messages from
2053 server to client in server's command.c. The old way violated
2054 protocol specification.
2056 Changes to silccore/silccommand.[ch]: removed
2057 silc_command_encode_status_payload -> not needed anymore,
2058 changed silc_command_encode_payload_va to accept extra
2059 argument on variable argument list. The argument type must
2060 now be provided to the function. Also, added new function:
2061 silc_command_encode_reply_payload_va which is same as
2062 normal command_encode_payload_va except command status type
2063 is provided as extra argument.
2065 Tue Jul 4 18:26:39 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2067 * Added ~./silc directory handling. The directory includes the
2068 public and private keys for the client.
2070 Added silc_client_check_silc_dir, silc_client_create_identifier
2071 and silc_client_load_keys.
2073 * Implemented SILC protocol compliant public key. Added public
2074 and private key saving to and loading from files.
2076 Added into silcpkcs.[ch]: silc_pkcs_encode_identifier,
2077 silc_pkcs_public_key_encode[_data], silc_pkcs_public_key_decode,
2078 silc_pkcs_private_key_encode[_data], silc_pkcs_private_key_decode,
2079 silc_pkcs_public_key_alloc, silc_pkcs_public_key_free,
2080 silc_pkcs_private_key_alloc and silc_pkcs_private_key_free.
2082 Implemented: silc_pkcs_save_[public/private]_key[_data] and
2083 silc_pkcs_load_[public/private]_key.
2085 Mon Jul 3 18:51:27 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2087 * Added silc_server_get_route (route.[ch]) to get connection
2088 data for the fastest route for given ID.
2090 * Implemented INVITE command on client and server. The command
2091 were re-defined in the SILC Protocol Specification and the
2092 implementation now complies with the specification.
2094 * Implemented PING command on client and server.
2096 * Implemented NAMES command on client and server. The server side
2097 supports currently only normal server not router server yet.
2098 Some changes to NAMES definition in SILC protocol specification.
2100 Sun Jul 2 18:23:01 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2102 * Implemented LEAVE command on client and server.
2104 * Previously deprecated SILC_PACKET_FORWARDED flag is now in use
2105 again. This change was made to the protocol as well. Server
2106 should not violate the protocol specification anymore.
2108 Fri Jun 30 14:03:26 EEST 2000 Pekka Riikonen <priikone@poseidon.pspt.fi>
2110 * Added SOCKS4 and SOCKS5 support to SILC client. SOCKS5
2111 was tested. SOCKS4 was not but should work anyway.
