1 TODO/bugs in Irssi SILC client
2 ==============================
4 o /key msg * list crashes the client
6 o Add local command to switch the channel's private key when channel has
7 several private keys. Currently sending channel messages with many
8 keys is not possible because changing the key is not possible by the
11 o JOINing to +a (requires passphrase to JOIN) does not work on autojoin.
12 Seems the passwords in the .silc/config has no effect.
14 o Add local commands to list the current server and client public keys
15 that the user has. And a local command to dump the contents of the
16 public key to the screen. Something like LISTKEYS, SHOWKEY...
18 o The QUIT command should wait for server's disconnection (at least for
19 a while) before exiting the application.
21 o The JOIN command's HELP is generated from Irssi IRCs JOIN help and
22 the syntax is not same in SILC. This must be fixed. Most likely
23 we must forget the Irssi's JOIN command and mimic it to get our
24 required syntax for it too.
26 o We should get rid of the clientconfig.[ch] in Irssi SILC and move the
27 cipher, hash, hmac and pkcs configuration to the Irssi SILC's config
30 o Add PERL scripting support from Irssi CVS.
32 o Extend the /HELP command to support sub commands or something. So
33 that user can say /help set mutual_authentication they would get
34 help of the mutual_authentication setting.
36 o Set different kind of settings, like, /set mutual_authentication,
37 /set key_exchange_timeout, /set conn_auth_timeout etc etc.
40 TODO/bugs In SILC Client Library
41 ================================
43 o JOIN command's argument handling is buggy. See the XXX in the code.
46 TODO/bugs In SILC Server
47 ========================
49 o After backup resuming protocol some of the server's SilcIDListData
50 on primary that came back online are NULL. Seems actually that the
51 udpate_client_by_server does not work since the client->router, and
52 the client->router->connection->user_data are not same, and they
55 o Server signoff notifys does not go to normal servers from routers.
57 o Channel user mode changes are notified unnecessarely when switching
58 to backup router on router crash.
60 o Change the sever to connect to another server from low ports (706)
61 and not from high ports. Currently we cannot do incoming connection
62 checking by remote port because the port is not fixed.
64 o Announcements are incomplete: channel topics are not announced,
65 user modes (UMODE) are not announced.
67 o Add a timeout to handling incoming JOIN commands. It should be
68 enforced that JOIN command is executed only once in a second or two
69 seconds. Now it is possible to accept n incoming JOIN commands
70 and process them without any timeouts. THis must be employed because
71 each JOIN command will create and distribute the new channel key
72 to everybody on the channel.
74 o Optimize the WHOIS and IDENTIFY commands to somehow check whether the
75 requested clients are on some channel that the server knows about. If
76 this is the case then the request is not needed to be forwarded to the
77 router. One specific optimization could be done with JOIN command.
78 If the previous command to the WHOIS and IDENTIFY commands are JOIN
79 command (from the client) it can be expected (though it must be
80 verified) that the client is resolving the users on the channel it just
81 joined. If server has done this once there is really no reason to
82 resolve it twice (from the router), it can reply directly back with
83 the information it knows. This is because the server would (will)
84 receive notifications from the router for users that are on a local
87 The same is with whowas command. Actually with all these commands
88 it should be checked also whether the requested information is local.
89 If it is, there is no reason to send it to the router, since the server
92 o Add support for sending the LIST command to primary router on normal
93 server to receive all the created channels. Currently the command
94 returns only the channels the server knows about. The protocol spec
95 does not prohibit of sending the LIST to the router.
97 o Incomplete IPv6 support:
99 o silcd/serverid.c and its routines supports only IPv4.
101 o Add perhaps /var/run/silcd.pid for PID information for the server.
103 o New configuration file format must be added. The new one will be
104 done using the dotconf config library (lib/dotconf). The following
105 tasks relates closely to this as well and must be done at the same time
106 when adding the new config file format:
108 o Server says that it is able to listen on multiple ports but
109 currently that is bogus. It can, but internals are for single
112 o Protocol execution timeouts are hard coded, should be
115 o IP address fields in configuration file should accept mask
116 format as well, IP/MASK, and not just plain IP.
118 o Connection classes should be actually implemented in
119 serverconfig.c. They can be defined but they are totally
120 ignored currently. And they should be redefined also.
123 TODO/bugs In SILC Libraries
124 ===========================
126 o Compression routines are missing. The protocol supports packet
127 compression thus it must be implemented. SILC Comp API must be
128 defined. zlib package is already included into the lib dir (in CVS,
129 not in distribution), but it is not used yet, and it requires some
130 tweaking on the Makefiles (we want static lib not shared).
132 o All payload parsing (decoding) functions should take unsigned char *
133 and uint32 as data and data length as arguments. Now some of the
134 routines do already that but most of the routines use SilcBuffer.
135 The SilcBuffer ones should be removed since buf->data and buf->len
136 is more convenient to use. These are currently only cosmetic changes
137 but at some point must be done to make the payload interfaces
140 o Incomplete IPv6 support:
142 o All network routines in lib/silcutil/silcnet.[ch] does not
144 o silc_id_render supports only IPv4 based ID's in the file
145 lib/silcutil/silcutil.c.
147 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
148 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
152 TODO/Bugs in native WIN32 support (libraries)
153 =============================================
155 o silc_net_create_connection_async does not work the same way than on
156 Unix. Do it with threads on WIN32. The function works but is not
157 actually async currently.
160 TODO In SILC Protocol
161 =====================
163 o If channel founder mode is set and the invite mode is set on channel
164 then the founder should be added to the list automatically so that
165 if the founder signoff's it will be able join again to the invite only
166 channel wihtout being invited.
172 o X.509 certificate support. SILC protocol supports certificates and
173 it would be great to have support for them. This is a big task as
174 support has to be made for ASN.1 as well. I've looked into OpenSSL
175 package as it has X.509 certificate support (and ASN.1 as well).
176 The code does not look very good to my eye but it has some potentials.
177 This should be looked at more closely.
179 Naturally own SILC Certificate API has to be defined regardles what
180 the actual X.509 library is (OpenSSL X.509 or something else). Other
181 choice is to write own X.509 library but I'm not going to do it -
182 I can help to migrate the OpenSSL X.509 into SILC and I can help if
183 someone would like to write the X.509 library - but I'm not going
184 to start writing one myself. Anyhow, the OpenSSL X.509 lib should
187 Other package that should be checked is the NSS's X509 library.
189 o SSH2 public keys support. Maybe - not really needed but could be
190 nice as SSH is widely used all over the place. SILC Protocol
191 supports SSH2 public keys.
193 o Cipher optimizations (asm, that this) at least for i386 would be nice.
