1 TODO/bugs in Irssi SILC client
2 ==============================
4 o GETKEY server will save the serverkey to the same filename as the
5 connected server and thus destroys the key.
7 o GETKEY server will show first, "there is no such nickname".
9 o Add local command to switch the channel's private key when channel has
10 several private keys. Currently sending channel messages with many
11 keys is not possible because changing the key is not possible by the
14 o JOINing to +a (requires passphrase to JOIN) does not work on autojoin.
15 Seems the passwords in the .silc/config has no effect.
17 o Add local commands to list the current server and client public keys
18 that the user has. And a local command to dump the contents of the
19 public key to the screen. Something like LISTKEYS, SHOWKEY...
21 o We should get rid of the clientconfig.[ch] in Irssi SILC and move the
22 cipher, hash, hmac and pkcs configuration to the Irssi SILC's config
25 o Add PERL scripting support from Irssi CVS.
27 o Extend the /HELP command to support sub commands or something. So
28 that user can say /help set mutual_authentication they would get
29 help of the mutual_authentication setting.
31 o Set different kind of settings, like, /set mutual_authentication,
32 /set key_exchange_timeout, /set conn_auth_timeout etc etc.
35 TODO/bugs In SILC Client Library
36 ================================
38 o The PRIVATE_MESSAGE_KEY packet is not handled (it is implemented
39 though). This should be added and perhaps new client operation
40 should be added to notify application that it was received and
41 set the key only if application wishes to set (accept the key) it.
43 o should /nick nick and /nick Nick cause the Nick to be Nick@host becase
46 o When changing own nickname and there exists a same nickname the library
47 can give the client now nickname in format nick@host. This is new
48 behaviour and maybe should be removed. The changer should always
49 get the one it wants and not have the formatted nickname.
51 o Remove the command destructor all together from the client, it is
52 not needed and its usage is buggy when the context is registered
53 to multiple pending commands.
55 o Additions to do after protocol version 1.1:
57 o Fix the NICK_CHANGE notify handling not to create new entry
58 for the changed client, but take the nickname from the notify
59 (removes need for resolving as well). Protocol TODO entry 3.
61 o Add support for list of errors in command replies. Protocol
65 TODO/bugs In SILC Server
66 ========================
68 o strerror messages from premature EOF's to signoff messages.
69 (add perhaps a socket error thingy to SilcSocketConnection).
71 o Backup router related issues
73 o Channel user mode changes are notified unnecessarely when
74 switching to backup router on router crash.
76 o Add a timeout to handling incoming JOIN commands. It should be
77 enforced that JOIN command is executed only once in a second or two
78 seconds. Now it is possible to accept n incoming JOIN commands
79 and process them without any timeouts. THis must be employed because
80 each JOIN command will create and distribute the new channel key
81 to everybody on the channel.
83 o New configuration file format must be added. The new one will be
84 done using the dotconf config library (lib/dotconf). The following
85 tasks relates closely to this as well and must be done at the same time
86 when adding the new config file format:
88 o Server says that it is able to listen on multiple ports but
89 currently that is bogus. It can, but internals are for single
92 o Protocol execution timeouts are hard coded, should be
95 o IP address fields in configuration file should accept mask
96 format as well, IP/MASK, and not just plain IP.
98 o If client's public key is saved in the server (and doing public key
99 authentication) then the hostname and the username information could
100 be taken from the public key. Should be a configuration option!
103 TODO/bugs In SILC Libraries
104 ===========================
106 o make install copies the symblic links from lib/silcsim/ and not
109 o WIN32 silc_net_create_connection_async does not work the same way
110 than on Unix. Do it with threads on WIN32. The function works but
111 is not actually async currently.
113 o Rewrite the lib/silcsim/silcsim.h. The SilcSimContext should be
114 private and silc_sim_alloc should take necessary arguments.
117 TODO in SILC Protocol
118 =====================
120 Current protocol version is 1.0. However, it is far from being perfect,
121 and needs to include additional features. Following protocol TODO entries
122 describe new stuff to be added to protocol versions 1.x.
124 1. Re-define the Status Payload: it is now 16 bits, split it into two
125 8 bits fields. First field includes status types from 0 - 9 and
126 10 - n *if* it is not an list of errors. If it is list of errors then
127 the first field includes 1, 2 and/or 3, and the second field includes
128 the error status 10 - n. This way it is possible to send multiple
129 errors (list of errors) and we have a way to tell the receiver that
130 there will be other errors as well. The second field is used only
131 if there is list of errors. If normal status, or normal (single)
132 error status the second field is set to zero, and must be ignored.
133 Hence, the status works same way as now except for list of errors.
134 To be included in protocol version 1.1.
136 2. Define that WHOIS and IDENTIFY commands must send list of errors
137 if multiple Client ID (or Channel ID and Server ID for IDENTIFY) was
138 requested and was not found. Each unfound entry must cause an error
139 command reply to the sender. Also define that errors must be sent
140 *after* sending successfully found entries (this way receiver may
141 ignore them). To be included in protocol version 1.1.
143 3. Define the NICK_CHANGE notify to send the changed nickname as a new
144 third argument. This will make the NICK_CHANGE notify handling easier
145 in the receiver's end (client primarily) since it removes the
146 requirement that receiver must resolve (using IDENTIFY or WHOIS) the
147 new Client ID received in the notify (because of the new nickname is
148 unknown). To be included in protocol version 1.1.
150 4. Add "request parameters" or similar to the WHOIS command, which can
151 be used to request various parameters (something not returned by
152 standard WHOIS command) about clients (info that could be fetched
153 even from clients). Additional specification (or appendix) should
154 be done to define the payload and the parameters. It could be used
155 to make the WHOIS command support various search conditions as well.
156 This would be the way to extend the WHOIS command to support various
157 new features without always making the command incompatible to previous
158 version. To be included in protocol version 1.1.
160 5. Inviting and banning by public key should be made possible. To be
161 included in protocol version 1.x.
163 6. Add perhaps SILENCE_USERS, SILENCE_OPERS channel user modes which
164 can be used to silence (moderate) normal users and opers (this set
165 only by founder). To be included in protocol version 1.1.
167 7. Channel Message Payload needs slight redesining to include the IV
168 field to the MAC generation of the payload. It is authenticated
169 by the packet's MAC but not by the payload's MAC. Since the IV
170 belongs to the payload, its integrity should be protected by the
171 payload MAC and not alone by packet MAC. To be included in protocol
178 o Compression routines are missing. The protocol supports packet
179 compression thus it must be implemented. SILC Zip API must be
180 defined. zlib package is already included into the lib dir (in CVS,
181 not in distribution), but it is not used yet, and it requires some
182 tweaking on the Makefiles (we want static lib not shared).
184 o Implement the defined SilcDH API. The definition is in
185 lib/silccrypt/silcdh.h.
187 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
188 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
191 o X.509 certificate support. SILC protocol supports certificates and
192 it would be great to have support for them. This is a big task as
193 support has to be made for ASN.1 as well. I've looked into OpenSSL
194 package as it has X.509 certificate support (and ASN.1 as well).
195 The code does not look very good to my eye but it has some potentials.
196 This should be looked at more closely.
198 Naturally own SILC Certificate API has to be defined regardles what
199 the actual X.509 library is (OpenSSL X.509 or something else). Other
200 choice is to write own X.509 library but I'm not going to do it -
201 I can help to migrate the OpenSSL X.509 into SILC and I can help if
202 someone would like to write the X.509 library - but I'm not going
203 to start writing one myself. Anyhow, the OpenSSL X.509 lib should
206 Other package that should be checked is the NSS's X509 library,
207 which I like more over OpenSSL package.
209 o SSH2 public keys support.
211 o OpenPGP certificate support.
213 o Cipher optimizations (asm, that this) at least for i386 would be nice.
