This patch fixes the following silly log messages:
'ID "XXX" already registered (on connection -1)!'
If the ID is already registered on a local connection, the local
connection ID is printed; and if the ID is connected via a remote
server, "via network" is displayed.
reported on #ngircd: pasting lots of lines into a channel can kill off
many people on the channel if the read buffer is drained quickly enough
and the client-side TCP can't keep up with the incoming data.
This implements a throttling scheme:
- an irc client may send up to 3 commands per second before a one second
pause is enforced.
- an irc client may send up to 256 bytes per second before a one second
pause is enforced.
After discussion with Alexander Barton, server <-> server links are
treated specially: There is no artificial limit on the number of bytes
sent per second, and up to 10 commands are processed per second before
a pause is enforced.
It may be neccessary to make those limits tuneable to accomondate larger
networks, but for now they are compile time values.
New_Server() can call Conn_Close() in its error paths,
but that function decrements the number of current active
connections. Thus we need to increment it earlier.
When a server is running with SSL/TLS support compiled in,
it is trivial to crash the server by sending an MOTD request
via another server in the network.
- ONLY servers without ssl/tls support compiled in are not affected.
Disabling SSL in the configuration (no ssl listening ports, etc)
does NOT help.
- servers that are running standalone (i.e., not connected to any
other servers) are not affected, either.
This affects all ngircd releases since ngircd 13 (earlier versions
have no SSL/TLS support).
When ngircd announces the list of currently known servers
to a new (connecting) server, it sent the introducer of
the servers instead of the top server.
Assuming this network:
irc1.example.com
|--irc2.example.com
| `--irc3.example.com
| `--irc4.example.com
`--irc5.example.com
When irc4 connects to irc3, irc3 tells irc4 that irc5 was
connected to irc2. (irc2 had introduced irc5 to irc3; but thats
not what ngircd should have sent to the new server).
This also placed users on the wrong servers.
that code does not really make sense -- the info
text is freely cofngiureable and des not follow a specific
format.
Also, that "+2" might have caused invalid memory accesses.
With this patch ngIRCd displays IPv6 addresses as "[<addr>]:<port>" when
accepting new connections and later, if no successful DNS lookup could
be made (or DNS is disabled altogether).
Don't echo multiple syntax error messages (461) on invalid commands,
but break after the first one.
In addition, this solves corrupted 'Unknown mode "+' messages.
When using OpenSSL, the following annoying "error" message was logged whenever
an encrypted connection was shut down in a orderly fashion:
TLS/SSL Connection shutdown: ConnSSL_Read: Unable to determine error
of course, this isn't an error at all.
commit 6bc2d3d06e
(New connection option CONN_RFC1459) forgot to adjust the ssl bitmasks.
The result is that when a compressed AND encrypted server link goes down
the memory allocated by zlib and the r/w buffers are no longer
free'd as the previous ConnSSL_Free() would then also remove the CONN_ZIP flag
from the flag mask.
Store the file name of channel key files and reopen them on each access
(on each JOIN command) insted of just storing the file handles.
This eliminates the special requirements (no delete) and makes sure
that always the actual file contents are used in all circumstances.
This patch introduces the new configuration variable "KeyFile" for
[Channel] sections in ngircd.conf. Here a file can be configured for each
pre-defined channel which contains individual channel keys for different
users. This file is line-based and must have the following syntax:
<user>:<nick>:<key>
<user> and <nick> can contain the wildcard character "*".
Please not that these channel keys are only in effect, when the channel
has a regular key set using channel mode "k"!
commit 2546a13ad2
('Cumulative Message Patch') broke PRIVMSG to channels
containing dots.
Fix this by switching evaluation order:
Check first if the target matches a existing channel and only do a check
for target masks if that failed.
PRIVMSG with host/server masks is described in RFC 2812, section 3.3.1.
Makes one wonder how a server is _really_ supposed to tell the difference
between hostmasks and channel names.
Sigh.
when ngircd is build without DEBUG enabled, LOG_DEBUG messages
are always discarded.
To avoid the extra code, ngircd has a LogDebug() wrapper which
gets removed by the compiler when compiling without DEBUG defined.
Update a few functings which were using the
Log(LOG_DEBUG, .. interface directly without #ifdef DEBUG guards.

Silly bug: the condition of a while() loop in the Channel_Exit() function
used the wrong variable and therefore got never executed ...
This bug is in the code since the beginning (see commit bb19cfda in 2002);
shame on me!
in the same vein as the earlier commit:
cast posix data types (pid_t, ...) to long and use
%ld as format specifier. This will avoid problems
when sizeof(int) != sizeof(type).
We could also cast to int, but this might truncate the value.
Reported by Christoph Biedl:
ngircd[21581]: Running as user irc(39), group irc(39), with PID 140733193409613.
cast pid_t to long to avoid this.
While we are there, cast uid_t and gid_t, too.
- Fix formatting of some log messages, mostly punctuation.
- cb_Connect_to_Server(): don't use string concatenation, because it
is not supported by pre-ANSI C compilers ...
