1 TODO/bugs in Irssi SILC client
2 ==============================
4 o Add KNOCKOUT local command. It should kick an client from channel and
5 set a ban for it for number of seconds.
7 o Add KICKBAN local command. Kicks and bans the specified client.
10 TODO/bugs In SILC Client Library
11 ================================
13 o The client library must manage somehow when receiving client that has
14 same nickname, same server, same username but different Client ID than
15 what we have in the cache. It is now assumed that they are different
16 client but it might not be. It should at least number the clients
17 using the client->num so that they can be accessed from the user
18 interface separately or it could just remove the old client unless
19 it is on some channels.
21 o Add local commands to list the current server and client public keys
22 that the user has. And a local command to dump the contents of the
23 public key to the screen.
25 o Add client library parameters or options that handle what kind of
26 messages the library should print out (using `say' client operation,
27 for example) and what is left for the application to print. The
28 appliation could for example set that it handles all command printing
29 but all error printing should be handled by the library, etc...
30 This is not a showstopper.
32 o Input line on UI is buggy. Cursor movement etc bugs. Too lazy to
36 TODO/bugs In SILC Server
37 ========================
39 o The SKE protocol in the server does not verify the remote hosts
40 (the router's) public key at all. All public keys are accepted without
41 verification - this obviously is not secure.
43 o When server quits and all clients of that server are removed from all
44 channels the channel keys are re-generated for all clients. This is
45 a bug and should be done only once per channel after all clients of
46 the server has been removed.
48 o Incomplete IPv6 support:
50 o silc_server_get_users_on_channel does not support IPv6 based
52 o silc_server_route_get and the route code in general supports
54 o silcd/serverid.c and its routines supports only IPv4.
56 o DNS/IP lookup blocks the server. This must be fixed. Check the
57 resolver stuff (resolver(3), resolver(5)). Either we have to do the
58 own resolver stuff (through scheduler, if possible without writing
59 too much own stuff) or use threads.
61 o The backup router support described in the protocol specification
62 should be done at some point.
64 o New configuration file format must be added. The new one will be
65 done using the dotconf config library (lib/dotconf). The following
66 tasks relates closely to this as well and must be done at the same time
67 when adding the new config file format:
69 o Server says that it is able to listen on multiple ports but
70 currently that is bogus. It can, but internals are for single
73 o Protocol execution timeouts are hard coded, should be
76 o IP address fields in configuration file should accept mask
77 format as well, IP/MASK, and not just plain IP.
79 o Connection classes should be actually implemented in
80 serverconfig.c. They can be defined but they are totally
81 ignored currently. And they should be redefined also.
84 TODO/bugs In SILC Libraries
85 ===========================
87 o Incomplete IPv6 support:
89 o All network routines in lib/silcutil/silcnet.[ch] does not
91 o silc_id_render supports only IPv4 based ID's in the file
92 lib/silcutil/silcutil.c.
94 o Compression routines are missing. The protocol supports packet
95 compression thus it must be implemented. SILC Comp API must be
96 defined. zlib package is already included into the lib dir (in CVS,
97 not in distribution), but it is not used yet, and it requires some
98 tweaking on the Makefiles (we want static lib not shared).
100 o The CAST cipher is not compiled currently due to compilation errors;
101 check those. Cast is in lib/silccrypt/cast.c.
103 o All payload parsing (decoding) functions should take unsigned char *
104 and uint32 as data and data length as arguments. Now some of the
105 routines do already that but most of the routines use SilcBuffer.
106 The SilcBuffer ones should be removed since buf->data and buf->len
107 is more convenient to use. However, the silc_buffer_[un]format
108 routines support only SilcBuffer so they would require reallocation
109 of SilcBuffer. Maybe support for raw data (and not just SilcBuffer)
110 should be added silc_buffer_[un]format_? routines. These are currently
111 only cosmetic changes but at some point must be done to make the
112 payload interfaces consistent.
118 o Pthreads support. A lot of problems are solved with server (and with
119 client as well) if we add pthread support. We can forget things such
120 as non-blocking connecting etc, and we can do things such as DNS/IP
121 lookups async. The server itself also benefits great deal from
122 threads, especially from performance point of view.
124 But, this is not a small task and almost entire SILC Library has to
125 be made re-entrant. Own API is probably added for the threads support
126 to make changes in the future as painless as possible. So the API
127 would have things like silc_mutex_lock, silc_mutex_unlock and
130 o X.509 certificate support. SILC protocol supports certificates and
131 it would be great to have support for them. This is a big task as
132 support has to be made for ASN.1 as well. I've looked into OpenSSL
133 package as it has X.509 certificate support (and ASN.1 as well).
134 The code does not look very good to my eye but it has some potentials.
135 This should be looked at more closely.
137 Naturally own SILC Certificate API has to be defined regardles what
138 the actual X.509 library is (OpenSSL X.509 or something else). Other
139 choice is to write own X.509 library but I'm not going to do it -
140 I can help to migrate the OpenSSL X.509 into SILC and I can help if
141 someone would like to write the X.509 library - but I'm not going
142 to start writing one myself. Anyhow, the OpenSSL X.509 lib should
145 o SSH2 public keys support. Maybe - not really needed but could be
146 nice as SSH is widely used all over the place. SILC Protocol
147 supports SSH2 public keys.
149 o Cipher optimizations (asm, that this) at least for i386 would be nice.
