1 TODO/bugs in Irssi SILC client
2 ==============================
4 o /NAMES kees showing things wrong after JOIN and after ppl has left
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 The JOIN command's HELP is generated from Irssi IRCs JOIN help and
20 the syntax is not same in SILC. This must be fixed. Most likely
21 we must forget the Irssi's JOIN command and mimic it to get our
22 required syntax for it too.
24 o We should get rid of the clientconfig.[ch] in Irssi SILC and move the
25 cipher, hash, hmac and pkcs configuration to the Irssi SILC's config
28 o Add PERL scripting support from Irssi CVS.
30 o Extend the /HELP command to support sub commands or something. So
31 that user can say /help set mutual_authentication they would get
32 help of the mutual_authentication setting.
34 o Set different kind of settings, like, /set mutual_authentication,
35 /set key_exchange_timeout, /set conn_auth_timeout etc etc.
38 TODO/bugs In SILC Client Library
39 ================================
41 o JOIN command's argument handling is buggy. See the XXX in the code.
43 o key agreement with itself causes the packet sequence numbers go grazy.
46 TODO/bugs In SILC Server
47 ========================
49 o After backup resume protocol the TOPIC_SET was not handled correctly
50 by all (unknown Channel ID).
52 o Channel user mode changes are notified unnecessarely when switching
53 to backup router on router crash.
55 o Change the server to connect to another server from low ports (706)
56 and not from high ports. Currently we cannot do incoming connection
57 checking by remote port because the port is not fixed.
59 o Announcements are incomplete: channel topics are not announced,
60 user modes (UMODE) are not announced.
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 Optimize the WHOIS and IDENTIFY commands to somehow check whether the
70 requested clients are on some channel that the server knows about. If
71 this is the case then the request is not needed to be forwarded to the
72 router. One specific optimization could be done with JOIN command.
73 If the previous command to the WHOIS and IDENTIFY commands are JOIN
74 command (from the client) it can be expected (though it must be
75 verified) that the client is resolving the users on the channel it just
76 joined. If server has done this once there is really no reason to
77 resolve it twice (from the router), it can reply directly back with
78 the information it knows. This is because the server would (will)
79 receive notifications from the router for users that are on a local
82 The same is with whowas command. Actually with all these commands
83 it should be checked also whether the requested information is local.
84 If it is, there is no reason to send it to the router, since the server
87 o Add support for sending the LIST command to primary router on normal
88 server to receive all the created channels. Currently the command
89 returns only the channels the server knows about. The protocol spec
90 does not prohibit of sending the LIST to the router.
92 o Incomplete IPv6 support:
94 o silcd/serverid.c and its routines supports only IPv4.
96 o New configuration file format must be added. The new one will be
97 done using the dotconf config library (lib/dotconf). The following
98 tasks relates closely to this as well and must be done at the same time
99 when adding the new config file format:
101 o Server says that it is able to listen on multiple ports but
102 currently that is bogus. It can, but internals are for single
105 o Protocol execution timeouts are hard coded, should be
108 o IP address fields in configuration file should accept mask
109 format as well, IP/MASK, and not just plain IP.
111 o Connection classes should be actually implemented in
112 serverconfig.c. They can be defined but they are totally
113 ignored currently. And they should be redefined also.
116 TODO/bugs In SILC Libraries
117 ===========================
119 o Optimizations to lib/silcsftp
121 o Do not allocate new req for every client request. Use
122 preallocated requests and recycle them.
124 o Use SilcList instead of SilcDList for requests. It is faster.
126 o Do not allocate new buffer for every packet. Use preallocated
127 buffer and reallocate only if necessary.
129 o Compression routines are missing. The protocol supports packet
130 compression thus it must be implemented. SILC Comp API must be
131 defined. zlib package is already included into the lib dir (in CVS,
132 not in distribution), but it is not used yet, and it requires some
133 tweaking on the Makefiles (we want static lib not shared).
135 o All payload parsing (decoding) functions should take unsigned char *
136 and uint32 as data and data length as arguments. Now some of the
137 routines do already that but most of the routines use SilcBuffer.
138 The SilcBuffer ones should be removed since buf->data and buf->len
139 is more convenient to use. These are currently only cosmetic changes
140 but at some point must be done to make the payload interfaces
143 o Incomplete IPv6 support:
145 o All network routines in lib/silcutil/silcnet.[ch] does not
147 o silc_id_render supports only IPv4 based ID's in the file
148 lib/silcutil/silcutil.c.
150 o Add builtin SOCKS and HTTP Proxy support, well the SOCKS at least.
151 SILC currently supports SOCKS4 and SOCKS5 but it needs to be compiled
155 TODO/Bugs in native WIN32 support (libraries)
156 =============================================
158 o silc_net_create_connection_async does not work the same way than on
159 Unix. Do it with threads on WIN32. The function works but is not
160 actually async currently.
163 TODO In SILC Protocol
164 =====================
166 o If channel founder mode is set and the invite mode is set on channel
167 then the founder should be added to the list automatically so that
168 if the founder signoff's it will be able join again to the invite only
169 channel wihtout being invited.
175 o X.509 certificate support. SILC protocol supports certificates and
176 it would be great to have support for them. This is a big task as
177 support has to be made for ASN.1 as well. I've looked into OpenSSL
178 package as it has X.509 certificate support (and ASN.1 as well).
179 The code does not look very good to my eye but it has some potentials.
180 This should be looked at more closely.
182 Naturally own SILC Certificate API has to be defined regardles what
183 the actual X.509 library is (OpenSSL X.509 or something else). Other
184 choice is to write own X.509 library but I'm not going to do it -
185 I can help to migrate the OpenSSL X.509 into SILC and I can help if
186 someone would like to write the X.509 library - but I'm not going
187 to start writing one myself. Anyhow, the OpenSSL X.509 lib should
190 Other package that should be checked is the NSS's X509 library.
192 o SSH2 public keys support. Maybe - not really needed but could be
193 nice as SSH is widely used all over the place. SILC Protocol
194 supports SSH2 public keys.
196 o Cipher optimizations (asm, that this) at least for i386 would be nice.
