1 TODO/bugs in Irssi SILC client
2 ==============================
4 o Add the SFTP support.
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 JOIN command's HELP is generated from Irssi IRCs JOIN help and
19 the syntax is not same in SILC. This must be fixed. Most likely
20 we must forget the Irssi's JOIN command and mimic it to get our
21 required syntax for it too.
23 o We should get rid of the clientconfig.[ch] in Irssi SILC and move the
24 cipher, hash, hmac and pkcs configuration to the Irssi SILC's config
27 o Add PERL scripting support from Irssi CVS.
29 o Extend the /HELP command to support sub commands or something. So
30 that user can say /help set mutual_authentication they would get
31 help of the mutual_authentication setting.
33 o Set different kind of settings, like, /set mutual_authentication,
34 /set key_exchange_timeout, /set conn_auth_timeout etc etc.
37 TODO/bugs In SILC Client Library
38 ================================
40 o Add the SFTP support.
42 o JOIN command's argument handling is buggy. See the XXX in the code.
45 TODO/bugs In SILC Server
46 ========================
48 o After backup resume protocol the TOPIC_SET was not handled correctly
49 by all (unknown Channel ID).
51 o Server signoff notifys does not go to normal servers from routers.
53 o Channel user mode changes are notified unnecessarely when switching
54 to backup router on router crash.
56 o Change the server to connect to another server from low ports (706)
57 and not from high ports. Currently we cannot do incoming connection
58 checking by remote port because the port is not fixed.
60 o Announcements are incomplete: channel topics are not announced,
61 user modes (UMODE) are not announced.
63 o Add a timeout to handling incoming JOIN commands. It should be
64 enforced that JOIN command is executed only once in a second or two
65 seconds. Now it is possible to accept n incoming JOIN commands
66 and process them without any timeouts. THis must be employed because
67 each JOIN command will create and distribute the new channel key
68 to everybody on the channel.
70 o Optimize the WHOIS and IDENTIFY commands to somehow check whether the
71 requested clients are on some channel that the server knows about. If
72 this is the case then the request is not needed to be forwarded to the
73 router. One specific optimization could be done with JOIN command.
74 If the previous command to the WHOIS and IDENTIFY commands are JOIN
75 command (from the client) it can be expected (though it must be
76 verified) that the client is resolving the users on the channel it just
77 joined. If server has done this once there is really no reason to
78 resolve it twice (from the router), it can reply directly back with
79 the information it knows. This is because the server would (will)
80 receive notifications from the router for users that are on a local
83 The same is with whowas command. Actually with all these commands
84 it should be checked also whether the requested information is local.
85 If it is, there is no reason to send it to the router, since the server
88 o Add support for sending the LIST command to primary router on normal
89 server to receive all the created channels. Currently the command
90 returns only the channels the server knows about. The protocol spec
91 does not prohibit of sending the LIST to the router.
93 o Incomplete IPv6 support:
95 o silcd/serverid.c and its routines supports only IPv4.
97 o Add perhaps /var/run/silcd.pid for PID information for the server.
99 o New configuration file format must be added. The new one will be
100 done using the dotconf config library (lib/dotconf). The following
101 tasks relates closely to this as well and must be done at the same time
102 when adding the new config file format:
104 o Server says that it is able to listen on multiple ports but
105 currently that is bogus. It can, but internals are for single
108 o Protocol execution timeouts are hard coded, should be
111 o IP address fields in configuration file should accept mask
112 format as well, IP/MASK, and not just plain IP.
114 o Connection classes should be actually implemented in
115 serverconfig.c. They can be defined but they are totally
116 ignored currently. And they should be redefined also.
119 TODO/bugs In SILC Libraries
120 ===========================
122 o Add some silc_rng_get_byte_fast that read directly from /dev/urandom.
123 That can be used for padding generation. The current is too slow.
125 o Compression routines are missing. The protocol supports packet
126 compression thus it must be implemented. SILC Comp API must be
127 defined. zlib package is already included into the lib dir (in CVS,
128 not in distribution), but it is not used yet, and it requires some
129 tweaking on the Makefiles (we want static lib not shared).
131 o All payload parsing (decoding) functions should take unsigned char *
132 and uint32 as data and data length as arguments. Now some of the
133 routines do already that but most of the routines use SilcBuffer.
134 The SilcBuffer ones should be removed since buf->data and buf->len
135 is more convenient to use. These are currently only cosmetic changes
136 but at some point must be done to make the payload interfaces
139 o Incomplete IPv6 support:
141 o All network routines in lib/silcutil/silcnet.[ch] does not
143 o silc_id_render supports only IPv4 based ID's in the file
144 lib/silcutil/silcutil.c.
146 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
147 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
151 TODO/Bugs in native WIN32 support (libraries)
152 =============================================
154 o silc_net_create_connection_async does not work the same way than on
155 Unix. Do it with threads on WIN32. The function works but is not
156 actually async currently.
159 TODO In SILC Protocol
160 =====================
162 o If channel founder mode is set and the invite mode is set on channel
163 then the founder should be added to the list automatically so that
164 if the founder signoff's it will be able join again to the invite only
165 channel wihtout being invited.
171 o X.509 certificate support. SILC protocol supports certificates and
172 it would be great to have support for them. This is a big task as
173 support has to be made for ASN.1 as well. I've looked into OpenSSL
174 package as it has X.509 certificate support (and ASN.1 as well).
175 The code does not look very good to my eye but it has some potentials.
176 This should be looked at more closely.
178 Naturally own SILC Certificate API has to be defined regardles what
179 the actual X.509 library is (OpenSSL X.509 or something else). Other
180 choice is to write own X.509 library but I'm not going to do it -
181 I can help to migrate the OpenSSL X.509 into SILC and I can help if
182 someone would like to write the X.509 library - but I'm not going
183 to start writing one myself. Anyhow, the OpenSSL X.509 lib should
186 Other package that should be checked is the NSS's X509 library.
188 o SSH2 public keys support. Maybe - not really needed but could be
189 nice as SSH is widely used all over the place. SILC Protocol
190 supports SSH2 public keys.
192 o Cipher optimizations (asm, that this) at least for i386 would be nice.
