1 TODO/bugs in Irssi SILC client
2 ==============================
4 o Fix the silc_channels_join to parse the command like, with fe.
5 silc_parse_command_line, because currently it ignores all options,
6 including passphrase which makes autojoin impossible to +a channels.
7 Other important options are ignored too.
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 Add the server/router operator info to the statusbar.
16 o /cumode for unknown nick does not give any error message.
19 TODO/bugs In SILC Client Library
20 ================================
22 o The PRIVATE_MESSAGE_KEY packet is not handled (it is implemented
23 though). This should be added and perhaps new client operation
24 should be added to notify application that it was received and
25 set the key only if application wishes to set (accept the key) it.
27 o Additions to do after protocol version 1.1:
29 o Fix the NICK_CHANGE notify handling not to create new entry
30 for the changed client, but take the nickname from the notify
31 (removes need for resolving as well). Protocol TODO entry 3.
33 o Add support for list of errors in command replies. Protocol
37 TODO/bugs In SILC Server
38 ========================
40 o Configuration file additions:
42 o Add version handling, to allow, disallow certain versions to
45 o Add incoming connection frequency, incoming connection frequency
46 for single IP address, key exchange frequency, key exchange
47 frequency for single IP. Add also frequency base.
49 o Add hashed passwords to config file.
51 o Add rehashing support.
53 o If server send CUMODE_CHANGE notify (like setting founder) to router
54 and router does not have founder on channel (founder is left or there's
55 no founder on channel at all), the router will accept the server's
56 founder mode change, even though it perhaps should not do that.
58 o The router should check for validity of received notify packets from
59 servers (after all buggy servers may send notify that is actually
60 something that should have not been sent).
62 o Add a timeout to handling incoming JOIN commands. It should be
63 enforced that JOIN command is executed only once in a second or two
64 seconds. Now it is possible to accept n incoming JOIN commands
65 and process them without any timeouts. THis must be employed because
66 each JOIN command will create and distribute the new channel key
67 to everybody on the channel.
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 Lots of statistics updating is missing around the server.
76 o If client's public key is saved in the server (and doing public key
77 authentication) then the hostname and the username information could
78 be taken from the public key. Should be a configuration option!
81 TODO/bugs In SILC Libraries
82 ===========================
84 o Fix possible buffer overflows in silc_id_render function.
86 o WIN32 silc_net_create_connection_async does not work the same way
87 than on Unix. Do it with threads on WIN32. The function works but
88 is not actually async currently.
90 o Rewrite the lib/silcsim/silcsim.h. The SilcSimContext should be
91 private and silc_sim_alloc should take necessary arguments.
93 o SILC RNG does not implement random seed files, and they should be
96 o The SilcSocketConnection in the SFTP interface is actually redundant
97 and should perhaps be removed. The application can save it in the
98 context it provides, which is delivered by SFTP libary to all
101 o EPOC specific additions/changes required:
103 o lib/silcutil/epoc routines missing or not completed.
105 o Rewrite the lib/silcutil/silcprotocol.[ch] not to have
106 [un]register functions, but to make it context based all the
107 way. The alloc should take as argument the protocol type and
108 its callback (not only final callback). It is not good that we
109 have now global list of registered protocols.
111 o Global RNG should not be allowed on EPOC, since it won't
112 work. Every function in library that calls the global RNG must
113 also take the RNG context as argument so that application can
114 provide it if it doesn't want to use global RNG.
116 o Think some solution to the global crypto lists in lib/silccrypt.
117 They won't work on EPOC.
119 o Something needs to be thought to the logging globals as well,
120 like silc_debug etc. They won't work on EPOC. Perhaps logging
121 and debugging is to be disabled on EPOC.
124 TODO in Toolkit Documentation
125 =============================
127 Stuff that needs to be done in order to complete the Tooolkit Reference
130 o Lots of ROBOdoc header formatting is undone in lib/silcutil, and
133 o Write "Programming with Toolkit" document, describing how to build
134 Toolkit, how the build system works, where is everything, how
135 new (external) projects can be glued into Toolkit (use irssi as an
136 example), and how external projects can use Toolkit without gluing into
137 it (how to link etc), debugging, architecture, types, etc.
139 o Write "Platform Implementations" document to describe what platforms
140 Toolkit support, what has been implemented, what has not been, what
141 wors differently etc.
144 TODO in SILC Protocol
145 =====================
147 Current protocol version is 1.0. However, it is far from being perfect,
148 and needs to include additional features. Following protocol TODO entries
149 describe new stuff to be added to protocol versions 1.x.
151 1. Re-define the Status Payload: it is now 16 bits, split it into two
152 8 bits fields. First field includes status types from 0 - 9 and
153 10 - n *if* it is not an list of errors. If it is list of errors then
154 the first field includes 1, 2 and/or 3, and the second field includes
155 the error status 10 - n. This way it is possible to send multiple
156 errors (list of errors) and we have a way to tell the receiver that
157 there will be other errors as well. The second field is used only
158 if there is list of errors. If normal status, or normal (single)
159 error status the second field is set to zero, and must be ignored.
160 Hence, the status works same way as now except for list of errors.
161 To be included in protocol version 1.1.
163 2. Define that WHOIS and IDENTIFY commands must send list of errors
164 if multiple Client ID (or Channel ID and Server ID for IDENTIFY) was
165 requested and was not found. Each unfound entry must cause an error
166 command reply to the sender. Also define that errors must be sent
167 *after* sending successfully found entries (this way receiver may
168 ignore them). To be included in protocol version 1.1.
170 3. Define the NICK_CHANGE notify to send the changed nickname as a new
171 third argument. This will make the NICK_CHANGE notify handling easier
172 in the receiver's end (client primarily) since it removes the
173 requirement that receiver must resolve (using IDENTIFY or WHOIS) the
174 new Client ID received in the notify (because of the new nickname is
175 unknown). To be included in protocol version 1.1.
177 4. Add "request parameters" or similar to the WHOIS command, which can
178 be used to request various parameters (something not returned by
179 standard WHOIS command) about clients (info that could be fetched
180 even from clients). Additional specification (or appendix) should
181 be done to define the payload and the parameters. It could be used
182 to make the WHOIS command support various search conditions as well.
183 This would be the way to extend the WHOIS command to support various
184 new features without always making the command incompatible to previous
185 version. To be included in protocol version 1.1.
187 5. Inviting and banning by public key should be made possible. To be
188 included in protocol version 1.x.
190 6. Add perhaps SILENCE_USERS, SILENCE_OPERS channel user modes which
191 can be used to silence (moderate) normal users and opers (this set
192 only by founder). To be included in protocol version 1.1.
194 7. Channel Message Payload needs slight redesining to include the IV
195 field to the MAC generation of the payload. It is authenticated
196 by the packet's MAC but not by the payload's MAC. Since the IV
197 belongs to the payload, its integrity should be protected by the
198 payload MAC and not alone by packet MAC. To be included in protocol
201 8. Remove the administrative commands from the protocol all together.
202 It does not make sense for the protocol to define how a server is
203 reconnected or shutdown, since they are implementation and
204 configuration issues. Besides protocol provides only limited set of
205 administrative commands and cannot define all that one could imagine.
206 To be included in protocol version 1.1.
208 9. Add SILC_MESAGE_FLAG_REPLY for being other side to the
209 SILC_MESSAGE_FLAG_REQUEST. Add generic SILC_MESSAGE_FLAG_DATA, which
210 can include generic payload, which can include generic data. The
211 payload definition is left out for now. To be included in protocol
214 10. Check command reply error status types in various commands,
215 specifically NO_FOPRIV is missing from many commands. To be
216 included in protocol version 1.1.
