Without this patch, the server becomes removed from the network and
the client structures, but the connection isn't shut down at all ...

Use ps(1) flag "-a" (as well as "-f"):
"Select all processes except both session leaders (see getsid(2)) and
processes not associated with a terminal."
Thanks to Götz Hoffart for reporting this problem!

Citing an email from Florian to the ngIRCd mailing list:
"I wonder what the expected behaviour is when Conf_MorePrivacy is changed
from 'yes' to 'no' and the config is reloaded.
At the moment, WHOWAS will start giving out information on Users that
were connected during Conf_MorePrivacy=yes period. If this is not
wanted, Client_RegisterWhowas() should be changed to not store a record
when Conf_MorePrivacy is enabled."
And I think it is "not wanted" :-)

For outgoing connections, we use 2048 (DH_BITS) since commit 49b2d0e.
This patch enables ngIRCd to accept incoming connections from other servers
and clients that use at least 1024 bits (and no longer requires 2048 for
incoming connections, too).
Patch proposed by Florian Westphal.

better distribution.

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.

Remove functions ssl_print_configvar() and ConfSSL_Puts(), introduce
new function CheckFileReadable().
|
|
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

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.
