1 TODO/bugs in Irssi SILC client
2 ==============================
4 o Add local command to switch the channel's private key when channel has
5 several private keys. Currently sending channel messages with many
6 keys is not possible because changing the key is not possible by the
9 o JOINing to +a (requires passphrase to JOIN) does not work on autojoin.
10 Seems the passwords in the .silc/config has no effect.
12 o Add local commands to list the current server and client public keys
13 that the user has. And a local command to dump the contents of the
14 public key to the screen. Something like LISTKEYS, SHOWKEY...
16 o We should get rid of the clientconfig.[ch] in Irssi SILC and move the
17 cipher, hash, hmac and pkcs configuration to the Irssi SILC's config
20 o Add auto-nick support to Irssi, so that the user specified nickname
21 would be sent to the server immediately (automatically) after the
22 client is connected to the server.
24 o Add PERL scripting support from Irssi CVS.
26 o Extend the /HELP command to support sub commands or something. So
27 that user can say /help set mutual_authentication they would get
28 help of the mutual_authentication setting.
30 o Set different kind of settings, like, /set mutual_authentication,
31 /set key_exchange_timeout, /set conn_auth_timeout etc etc.
34 TODO/bugs In SILC Client Library
35 ================================
37 o The PRIVATE_MESSAGE_KEY packet is not handled (it is implemented
38 though). This should be added and perhaps new client operation
39 should be added to notify application that it was received and
40 set the key only if application wishes to set (accept the key) it.
42 o should /nick nick and /nick Nick cause the Nick to be Nick@host becase
45 o When changing own nickname and there exists a same nickname the library
46 can give the client now nickname in format nick@host. This is new
47 behaviour and maybe should be removed. The changer should always
48 get the one it wants and not have the formatted nickname.
50 o Additions to do after protocol version 1.1:
52 o Fix the NICK_CHANGE notify handling not to create new entry
53 for the changed client, but take the nickname from the notify
54 (removes need for resolving as well). Protocol TODO entry 3.
56 o Add support for list of errors in command replies. Protocol
60 TODO/bugs In SILC Server
61 ========================
63 o strerror messages from premature EOF's to signoff messages.
65 o Backup router related issues
67 o Channel user mode changes are notified unnecessarely when
68 switching to backup router on router crash.
70 o Add a timeout to handling incoming JOIN commands. It should be
71 enforced that JOIN command is executed only once in a second or two
72 seconds. Now it is possible to accept n incoming JOIN commands
73 and process them without any timeouts. THis must be employed because
74 each JOIN command will create and distribute the new channel key
75 to everybody on the channel.
77 o New configuration file format must be added. The new one will be
78 done using the dotconf config library (lib/dotconf). The following
79 tasks relates closely to this as well and must be done at the same time
80 when adding the new config file format:
82 o Server says that it is able to listen on multiple ports but
83 currently that is bogus. It can, but internals are for single
86 o Protocol execution timeouts are hard coded, should be
89 o IP address fields in configuration file should accept mask
90 format as well, IP/MASK, and not just plain IP.
92 o If client's public key is saved in the server (and doing public key
93 authentication) then the hostname and the username information could
94 be taken from the public key. Should be a configuration option!
97 TODO/bugs In SILC Libraries
98 ===========================
100 o make install copies the symblic links from lib/silcsim/ and not
103 o WIN32 silc_net_create_connection_async does not work the same way
104 than on Unix. Do it with threads on WIN32. The function works but
105 is not actually async currently.
107 o Rewrite the lib/silcsim/silcsim.h. The SilcSimContext should be
108 private and silc_sim_alloc should take necessary arguments.
111 TODO in SILC Protocol
112 =====================
114 Current protocol version is 1.0. However, it is far from being perfect,
115 and needs to include additional features. Following protocol TODO entries
116 describe new stuff to be added to protocol versions 1.x.
118 1. Re-define the Status Payload: it is now 16 bits, split it into two
119 8 bits fields. First field includes status types from 0 - 9 and
120 10 - n *if* it is not an list of errors. If it is list of errors then
121 the first field includes 1, 2 and/or 3, and the second field includes
122 the error status 10 - n. This way it is possible to send multiple
123 errors (list of errors) and we have a way to tell the receiver that
124 there will be other errors as well. The second field is used only
125 if there is list of errors. If normal status, or normal (single)
126 error status the second field is set to zero, and must be ignored.
127 Hence, the status works same way as now except for list of errors.
128 To be included in protocol version 1.1.
130 2. Define that WHOIS and IDENTIFY commands must send list of errors
131 if multiple Client ID (or Channel ID and Server ID for IDENTIFY) was
132 requested and was not found. Each unfound entry must cause an error
133 command reply to the sender. Also define that errors must be sent
134 *after* sending successfully found entries (this way receiver may
135 ignore them). To be included in protocol version 1.1.
137 3. Define the NICK_CHANGE notify to send the changed nickname as a new
138 third argument. This will make the NICK_CHANGE notify handling easier
139 in the receiver's end (client primarily) since it removes the
140 requirement that receiver must resolve (using IDENTIFY or WHOIS) the
141 new Client ID received in the notify (because of the new nickname is
142 unknown). To be included in protocol version 1.1.
144 4. Add "request parameters" or similar to the WHOIS command, which can
145 be used to request various parameters (something not returned by
146 standard WHOIS command) about clients (info that could be fetched
147 even from clients). Additional specification (or appendix) should
148 be done to define the payload and the parameters. It could be used
149 to make the WHOIS command support various search conditions as well.
150 This would be the way to extend the WHOIS command to support various
151 new features without always making the command incompatible to previous
152 version. To be included in protocol version 1.1.
154 5. Inviting and banning by public key should be made possible. To be
155 included in protocol version 1.x.
157 6. Add perhaps SILENCE_USERS, SILENCE_OPERS channel user modes which
158 can be used to silence (moderate) normal users and opers (this set
159 only by founder). To be included in protocol version 1.1.
165 o Compression routines are missing. The protocol supports packet
166 compression thus it must be implemented. SILC Zip API must be
167 defined. zlib package is already included into the lib dir (in CVS,
168 not in distribution), but it is not used yet, and it requires some
169 tweaking on the Makefiles (we want static lib not shared).
171 o Implement the defined SilcDH API. The definition is in
172 lib/silccrypt/silcdh.h.
174 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
175 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
178 o X.509 certificate support. SILC protocol supports certificates and
179 it would be great to have support for them. This is a big task as
180 support has to be made for ASN.1 as well. I've looked into OpenSSL
181 package as it has X.509 certificate support (and ASN.1 as well).
182 The code does not look very good to my eye but it has some potentials.
183 This should be looked at more closely.
185 Naturally own SILC Certificate API has to be defined regardles what
186 the actual X.509 library is (OpenSSL X.509 or something else). Other
187 choice is to write own X.509 library but I'm not going to do it -
188 I can help to migrate the OpenSSL X.509 into SILC and I can help if
189 someone would like to write the X.509 library - but I'm not going
190 to start writing one myself. Anyhow, the OpenSSL X.509 lib should
193 Other package that should be checked is the NSS's X509 library,
194 which I like more over OpenSSL package.
196 o SSH2 public keys support.
198 o OpenPGP certificate support.
200 o Cipher optimizations (asm, that this) at least for i386 would be nice.
