Restructure ngIRCd configuration, introduce [Limits] and [Options]
this patch contains:
* Fix for Conf_CloakUserToNick to make it conceal user details
* Adds MorePrivacy-feature
MorePrivacy censors some user information from being reported by the
server. Signon time and idle time is censored. Part and quit messages
are made to look the same. WHOWAS requests are silently dropped. All
of this is useful if one wish to conceal users that access the ngircd
servers from TOR or I2P.
This patch makes it possible to scrub incomming CTCP commands from
other servers and clients alike. The ngircd oper can enable it from
the config file, by adding "ScrubCTCP = yes" under [OPTIONS]. It is
default off.
CTCP can be used to profile IRC users (get user clients name and
version, and also their IP addresses). This is not something we like
to happen when user pseudonymity/secrecy is important.
The server silently drops incomming CTCP requests from both other
servers and from users. The server that scrubs CTCP will not forward
the CTCP requests to other servers in the network either, which can
spell trouble if not every oper knows about the CTCP-scrubbing.
Scrubbing CTCP commands also means that it is not possible to send
files between users.
There is one exception to the CTCP scrubbing performed: ACTION ("/me
commands") requests are not scrubbed. ACTION is not dangerous to users
(unless they use OTR, which does not encrypt CTCP requests) and most
users would be confused if they were just dropped.
A CTCP request looks like this:
ctcp_char, COMMAND, arg0, arg1, arg2, .. argN, ctcp_char
ctcp_char is 0x01. (just like bold is 0x02 and color is 0x03.)
They are sent as part of a message and can be delivered to channels
and users alike.
The intention of this restructuring is to make the [Global] section much
cleaner, so that it only contains variables that most installations must
adjust to the local requirements.
All the optional variables are moved to [Limits], for configurable limits
and timers of ngIRCd, and [Options], for optional features.
The old variables in the [Global] section are deprecated now, but still
recognized.
The io_event_create error handling seems to miss a 'return'
statement.
Fix this by moving io_event_create() call around so we do not
need the Conn_Close/Init calls in the error case.
problem is that some clients refuse to connect to severs that only offer
1024. For interoperability it would be best to just use 4096, but that
takes minutes, even on current hardware.
parse.c:284: warning: suggest parentheses around operand of '!' or
change '&' to '&&' or '!' to '~'
The expression looks dubious, this should probably be
an if-not-set, then... test.
When the write buffer space grows too large, ngircd has to disconnect
the client to avoid wasting too much memory.
ngircd logs this with a scary 'write buffer overflow' message.
Change this to a more descriptive wording.
Not all servers (and services!) using the RFC1459 protocol style send
prefixes on all commands; so don't require them to do so.
This relaxes the requirements introduced by commit 15775e679.
* 'master' of git://arthur.barton.de/ngircd-alex:
Do reverse lookups using the AF of the incoming connection
resolve: fix reverse lookups of client connections with ConnectIPv6=no
We re-use the same helper function for both forward lookups
(when we want to connect to a peer server) and for validation of reverse
loopups (where we make a lookup on the hostname returned
by a reverse lookup on the IP address that connected).
Problem:
When ConnectIPv6=no, the forward lookup helper sets the adderss family
to AF_INET, and, if out client connected via ipv6, we fail to validate
the result.
Thus move the ConnectIPvX check out of the helper.
Update Mac OS X Installer.app description bundle, so that the ngIRCd
package can only be installed on the root volume ("/"); and make sure
that all installed files and directories have correct ownership and
permissions.
we do not need this for cryptographic purposes, but we can do better
than plain srandom(getpid()).
Also, keep in mind that rng state is inherited across fork(), so re-init
it in the child.
* NoticeAuth:
Add documentation for "NoticeAuth" configuration option
Configuration: move "NoticeAuth" to GLOBAL section
New configuration option "NoticeAuth": send NOTICE AUTH on connect
When enabled, this configuration option lets ngIRCd send a PING with an
numeric "token" to clients logging in; and it will not become registered
in the network until the client responds with the correct PONG.
This is used by QuakeNet for example (ircu/snircd), and looks like this:
NICK nick
:irc.example.net PING :1858979527
USER user . . :real name
PONG 1858979527
:irc.example.net 001 nick :Welcome to the Internet Relay Network ...
Make sure that all commands received from other servers do have
valid prefixes.
Only exceptions are PING and ERROR commands that can occure without
prefixes when generated by the remote peer itself.
