Alexander Barton 594fdd02aa New RPL_WHOISHOST_MSG(378): show hostname and IP address
The numeric RPL_WHOISHOST_MSG(378) returns the DNS hostname (if
available) and the IP address of a client in the WHOIS reply.

Only the user itself and local IRC operators get this numeric.

Alexander Barton 1537c79132 G/K-Lines: only add and delete valid IRC masks 2012-01-22 18:53:16 +01:00
Alexander Barton e0c9931ad8 Check G/K-Lines before the client has been registered, too
This allows to use "*!<user>@<host>" or "*!*@<host>" masks to reject
clients even before receiving PASS, NICK and USER commands and before
forking authentication child processes which reduces resource usage.

Alexander Barton f2fa1045e2 Implement channel exception list (mode 'e')
This allows a channel operator to define exception masks that allow users
to join the channel even when a "ban" would match and prevent them from
joining: the exception list (e) overrides the ban list (b).

Alexander Barton c1656256df PRIVMSG/NOTICE: don't stop list processing on invalid target
Process further targets, even if one has been a server ID:
just skip this one with an error message and continue.

Alexander Barton 1f4711a547 Implement user mode 'C': require "same channel" to send message
If the target user of a PRIVMSG or NOTICE command has the user mode 'C'
set, it is required that both sender and receiver are on the same channel.

This prevents private flooding by completely unknown clients.

Alexander Barton 81cc5f82b5 Channel lists: Fix duplicate check and error messages

Alexander Barton d4d8102fc9 Don't stop join handling on faulty channel, skip it (part )
Commit 565523cb allowed processing of further channel names given to the
JOIN command when a single name was invalid.

After this patch, the JOIN command handler continues to process channel
name lists even after errors like "channel is full", "too many channels",
and the like and generates appropriate error messages for all the
channels given by the client.

Alexander Barton 77f68b4fd1 JOIN command: don't check channel limit if already member
Don't check the channel limit and don't report "too many channels"
when trying to join a channel that the client is already a member of.

It the limit is reached, a NOTICE is sent to the client and list

Alexander Barton 470d2e2362 RPL_ISUPPORT (numeric 005): Report MODES=<MAX_CMODES_ARG>
"Maximum number of channel modes with parameter allowed per MODE command."

Alexander Barton 888664435a Channel modes: really break handling when MAX_CMODES_ARG is hit
This fixes 98493077.
2012-01-06 17:43:20 +01:00
Alexander Barton 98493077a2 channel modes: only handle MAX_CMODES_ARG modes with arguments
Limit the MODE command to handle a maximum of MAX_CMODES_ARG (5) channel
modes that require an argument (+Ibkl) per call.

Please note: Further modes that require arguments are silently ignored
and end the handling of any further modes.
This is similar to the behavior of ircd2.11 (silently ignores but seems
to handle other modes) as well as ircd-seven (silently ignores but handles
some(!) other modes) ...
2012-01-06 17:27:29 +01:00
Alexander Barton 1fa2af5b3a Fix handling of channel mode sequence with/without arguments
For example, don't generate wrong error messages when handling

Alexander Barton 05cc9bf9b0 Conn_Write(): Make sure there is a client when detecting its type
The assert(client != NULL) got triggered during our tests, so there is
an error path that resulted in the connection being still established
(sock >= 0) but the client structure already freed.

So Conn_Write() should handle it!

Alexander Barton cc06e1ff89 Proc_Close(): Only close socket if it is still valid
It could be invalid when calling Proc_Close() a 2nd time, for exmaple,
which could happen when we hit a timeout doing IDENT requests :-(

Alexander Barton 9fbf592924 WHOIS command: make sure matching is case-insensitive
And make sure that RPL_ENDOFWHOIS replies with the unmodified mask
like it has been received from the client.

Alexander Barton adf92302bf WHOIS command: don't anser queries for IRC servers

2012-01-05 00:24:46 +01:00
Alexander Barton 566a451299 WHOIS command: make sure the reply ends with RPL_ENDOFWHOIS
Up to now, each reply for itself ended in RPL_ENDOFWHOIS and queries
for unknown nick names lacked the RPL_ENDOFWHOIS -- both is wrong.

Alexander Barton 6b62a5ec4f Add 1 second penalty for every further target on PRIVMSG/NOTICE
This reduces the possibility of flooding channels with commands like
"PRIVMSG/NOTICE #a,#n,#c,... :message" a little bit.

Problem noticed by Cahata -- thanks!

Alexander Barton b24d645ca1 Conn_SetPenalty(): Add new "penalty time" on each function call
Until now, the penalty time has only been set when longer as the
already set one, so it didn't accumulate.

And add documentation for and clean up code in Conn_SetPenalty() and
Conn_ResetPenalty() functions.
