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 Add local command to switch the channel's private key when channel has
8 several private keys. Currently sending channel messages with many
9 keys is not possible because changing the key is not possible by the
12 o JOINing to +a (requires passphrase to JOIN) does not work on autojoin.
13 Seems the passwords in the .silc/config has no effect.
15 o Add local commands to list the current server and client public keys
16 that the user has. And a local command to dump the contents of the
17 public key to the screen. Something like LISTKEYS, SHOWKEY...
19 o We should get rid of the clientconfig.[ch] in Irssi SILC and move the
20 cipher, hash, hmac and pkcs configuration to the Irssi SILC's config
23 o Add PERL scripting support from Irssi CVS.
25 o Extend the /HELP command to support sub commands or something. So
26 that user can say /help set mutual_authentication they would get
27 help of the mutual_authentication setting.
29 o Set different kind of settings, like, /set mutual_authentication,
30 /set key_exchange_timeout, /set conn_auth_timeout etc etc.
33 TODO/bugs In SILC Client Library
34 ================================
36 o The PRIVATE_MESSAGE_KEY packet is not handled (it is implemented
37 though). This should be added and perhaps new client operation
38 should be added to notify application that it was received and
39 set the key only if application wishes to set (accept the key) it.
41 o should /nick nick and /nick Nick cause the Nick to be Nick@host becase
44 o When changing own nickname and there exists a same nickname the library
45 can give the client now nickname in format nick@host. This is new
46 behaviour and maybe should be removed. The changer should always
47 get the one it wants and not have the formatted nickname.
49 o Remove the command destructor all together from the client, it is
50 not needed and its usage is buggy when the context is registered
51 to multiple pending commands.
53 o Additions to do after protocol version 1.1:
55 o Fix the NICK_CHANGE notify handling not to create new entry
56 for the changed client, but take the nickname from the notify
57 (removes need for resolving as well). Protocol TODO entry 3.
59 o Add support for list of errors in command replies. Protocol
63 TODO/bugs In SILC Server
64 ========================
66 o strerror messages from premature EOF's to signoff messages.
67 (add perhaps a socket error thingy to SilcSocketConnection).
69 o Backup router related issues
71 o Channel user mode changes are notified unnecessarely when
72 switching to backup router on router crash.
74 o Add a timeout to handling incoming JOIN commands. It should be
75 enforced that JOIN command is executed only once in a second or two
76 seconds. Now it is possible to accept n incoming JOIN commands
77 and process them without any timeouts. THis must be employed because
78 each JOIN command will create and distribute the new channel key
79 to everybody on the channel.
81 o New configuration file format must be added. The new one will be
82 done using the dotconf config library (lib/dotconf). The following
83 tasks relates closely to this as well and must be done at the same time
84 when adding the new config file format:
86 o Server says that it is able to listen on multiple ports but
87 currently that is bogus. It can, but internals are for single
90 o Protocol execution timeouts are hard coded, should be
93 o IP address fields in configuration file should accept mask
94 format as well, IP/MASK, and not just plain IP.
96 o If client's public key is saved in the server (and doing public key
97 authentication) then the hostname and the username information could
98 be taken from the public key. Should be a configuration option!
101 TODO/bugs In SILC Libraries
102 ===========================
104 o make install copies the symblic links from lib/silcsim/ and not
107 o WIN32 silc_net_create_connection_async does not work the same way
108 than on Unix. Do it with threads on WIN32. The function works but
109 is not actually async currently.
111 o Rewrite the lib/silcsim/silcsim.h. The SilcSimContext should be
112 private and silc_sim_alloc should take necessary arguments.
115 TODO in SILC Protocol
116 =====================
118 Current protocol version is 1.0. However, it is far from being perfect,
119 and needs to include additional features. Following protocol TODO entries
120 describe new stuff to be added to protocol versions 1.x.
122 1. Re-define the Status Payload: it is now 16 bits, split it into two
123 8 bits fields. First field includes status types from 0 - 9 and
124 10 - n *if* it is not an list of errors. If it is list of errors then
125 the first field includes 1, 2 and/or 3, and the second field includes
126 the error status 10 - n. This way it is possible to send multiple
127 errors (list of errors) and we have a way to tell the receiver that
128 there will be other errors as well. The second field is used only
129 if there is list of errors. If normal status, or normal (single)
130 error status the second field is set to zero, and must be ignored.
131 Hence, the status works same way as now except for list of errors.
132 To be included in protocol version 1.1.
134 2. Define that WHOIS and IDENTIFY commands must send list of errors
135 if multiple Client ID (or Channel ID and Server ID for IDENTIFY) was
136 requested and was not found. Each unfound entry must cause an error
137 command reply to the sender. Also define that errors must be sent
138 *after* sending successfully found entries (this way receiver may
139 ignore them). To be included in protocol version 1.1.
141 3. Define the NICK_CHANGE notify to send the changed nickname as a new
142 third argument. This will make the NICK_CHANGE notify handling easier
143 in the receiver's end (client primarily) since it removes the
144 requirement that receiver must resolve (using IDENTIFY or WHOIS) the
145 new Client ID received in the notify (because of the new nickname is
146 unknown). To be included in protocol version 1.1.
148 4. Add "request parameters" or similar to the WHOIS command, which can
149 be used to request various parameters (something not returned by
150 standard WHOIS command) about clients (info that could be fetched
151 even from clients). Additional specification (or appendix) should
152 be done to define the payload and the parameters. It could be used
153 to make the WHOIS command support various search conditions as well.
154 This would be the way to extend the WHOIS command to support various
155 new features without always making the command incompatible to previous
156 version. To be included in protocol version 1.1.
158 5. Inviting and banning by public key should be made possible. To be
159 included in protocol version 1.x.
161 6. Add perhaps SILENCE_USERS, SILENCE_OPERS channel user modes which
162 can be used to silence (moderate) normal users and opers (this set
163 only by founder). To be included in protocol version 1.1.
165 7. Channel Message Payload needs slight redesining to include the IV
166 field to the MAC generation of the payload. It is authenticated
167 by the packet's MAC but not by the payload's MAC. Since the IV
168 belongs to the payload, its integrity should be protected by the
169 payload MAC and not alone by packet MAC. To be included in protocol
176 o Compression routines are missing. The protocol supports packet
177 compression thus it must be implemented. SILC Zip API must be
178 defined. zlib package is already included into the lib dir (in CVS,
179 not in distribution), but it is not used yet, and it requires some
180 tweaking on the Makefiles (we want static lib not shared).
182 o Implement the defined SilcDH API. The definition is in
183 lib/silccrypt/silcdh.h.
185 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
186 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
189 o X.509 certificate support. SILC protocol supports certificates and
190 it would be great to have support for them. This is a big task as
191 support has to be made for ASN.1 as well. I've looked into OpenSSL
192 package as it has X.509 certificate support (and ASN.1 as well).
193 The code does not look very good to my eye but it has some potentials.
194 This should be looked at more closely.
196 Naturally own SILC Certificate API has to be defined regardles what
197 the actual X.509 library is (OpenSSL X.509 or something else). Other
198 choice is to write own X.509 library but I'm not going to do it -
199 I can help to migrate the OpenSSL X.509 into SILC and I can help if
200 someone would like to write the X.509 library - but I'm not going
201 to start writing one myself. Anyhow, the OpenSSL X.509 lib should
204 Other package that should be checked is the NSS's X509 library,
205 which I like more over OpenSSL package.
207 o SSH2 public keys support.
209 o OpenPGP certificate support.
211 o Cipher optimizations (asm, that this) at least for i386 would be nice.
