Use the currently "displayed hostname" (which can be cloaked!) for
hostname matching, not the real one. In other words: don't display
all the cloaked users on a specific real hostname!
Thanks to DNS <dns@rbose.org> for reporting this issue.

This patch introduces the new numeric 310(RPL_WHOISSERVICE) and enables
WHOIS to display information about IRC services. This numeric is used
for this purpose by InspIRCd, for example -- but as usual, other numerics
are in use, too, like 613 in UltimateIRCd ...
Please note that neither the Operator (+o) not the "bot status" (+B)
of an IRC service id displayed in the output.
Change suggested by Federico G. Schwindt <fgsch@lodoss.net>, Thanks.

This fixes the following warning, at least on OpenBSD 4.8:
irc-info.o(.text+0x2427): In function `IRC_WHO':
src/ngircd/irc-info.c:896: warning: strcpy() is almost always misused,
please use strlcpy()

Make sure that all log messages end with a correct punctuation mark.
The rules for formatting log messages are:
1. Add punctuation marks to all messages passed to the actual logging
functions like Log() and LogDebug().
2. Don't add any punctuation marks to messages that are stored in
variables for later use or are passed over the network.
3. IP addresses, DNS host names and IRC server names should be quoted.
4. Messages originating in the network should be quoted (at least if
they are "untrusted" or variable).
Most probably this patch doesn't fix all mistakes, but it should be a
good starting point ...

Now ngIRCd returns a more specific error message for numeric
ERR_NOTREGISTERED(451) when a regular user tries to use a command that
isn't allowed for users but for servers: ERR_NOTREGISTEREDSERVER(451).
|
|
Don't report ERR_NEEDMOREPARAMS(461) when a MDOE command with more modes
than nicknames is handled, as well as for channel limit and key changes
without specifying the limit or key parameters.
This is how a lot (all?) other IRC servers behave, including ircd2.11,
InspIRCd, and ircd-seven. And because of clients (tested with Textual and
mIRC) sending bogus MODE commands like "MODE -ooo nick", end-users got the
expected result as well as correct but misleading error messages ...
If ngIRCd is compiled using "strict mode", these errors are still reported.

This patch introduces the new function Conf_SSLInUse() to check when the
current server configuration requires the SSL subsystem to be initialized
and accounts incoming as well as outgoing connections -- so this fixes
commit bb20aeb9 ("Initialize SSL when needed only, and disable SSL on
errors") which only handled the inbound case ...

* bug145-ProvideHelp:
Use "${docdir}/Commands.txt" as help text file
Add a note that "help file" is updated on startup and REHASH only
Add doc/Commands.txt which should document all commands
Implement Help() function parsing and returning the help text
Document "HelpFile" in sample-ngircd.conf and ngircd.conf.5
Implement new configuration option "HelpFile"
IRC_HELP(): Code cleanup
Refactor Read_Motd() into Read_TextFile()
|

This function parses the already read in help text and sends the requested
portions to the user. Parsing is done as following when a user user
issues a "HELP <cmd>" command:
1. Search the file for a line "- <cmd>",
2. Output all subsequent lines that start with a TAB (ASCII 9) character
to the client using NOTICE commands, treat lines containing a single "."
after the TAB as empty lines.
3. Break at the first line not starting with a TAB character.
This format allows to have information to each command stored in this file
which will not be sent to an IRC user requesting help which enables us to
have additional annotations stored here which further describe the origin,
implementation details, or limits of the specific command.
A special "Intro" block is returned to the user when the HELP command is
used without a command name.
|
|
Ignore it and add a penalty time on all other link types.
|
|
This new configuration option allows to specify a specially formatted
text file which can be used by the HELP command to provide information
about the commands and their syntaxes.
|
|
|
|
Now this function allows to read arbitrary text files into arrays.
|
|
|
|
Only check the channel user modes of the initiator if he is joined to
this channel and not an IRC operator enforcing modes (which requires
the configuration option "OperCanUseMode" to be enabled), because trying
to check channel user modes of a non-member results in this assertion:
Assertion failed: (cl2chan != NULL), function Channel_UserModes,
file channel.c, line 742.
This closes bug #147, thanks to James Kirwill <james.kirwill@bk.ru>
for tracking this down!

This patch allows user names up to 20 characters when ngIRCd has not been
configured for "strict RFC mode".

Now ngIRCd uses two fields internally, one to store the "real" hostname
and one to save the "cloaked" hostname. And both fields can be set
independently using the "METADATA host" and "METADATA cloakhost" commands.
This allows "foreign servers" (aka "IRC services") to alter the real and
cloaked hostnames of clients without problems, even when the user itself
issues additional "MODE +x" and "MODE -x" commands.

This is correctly handled by ipaddr/ng_ipaddr.h today, and the check
in tool.h isn't required any more -- and caused errors on OpenBSD 5.0:

This flag indicates, that the server supports the enhanced "xop channel
user modes", like channel owner, admin, and halfop. This information is
used to make sure that no unsupported CHANINFO commands are sent to
servers not supporting such mode prefixes, for example.
|
|
|
|
Use "METADATA host" commands to let servers supporting this command
know which (possibly cloaked) hostname is in effect for a specific
client. This prevents "double cloaking" of hostnames and even cloaked
hostnames are in sync on all servers supporting "METADATA" now.
|
|
A client for which a METADATA command has been received from one of
its peers got the client flag "M" set. So it's safe to assume that
such a client gets "METADATA host" commands for its cloaked hostname
and the server must not cloak the hostname on its own, even when the
client mode "+x" is set.
|
|
The METADATA command can be used by other servers to update "metadata"
of registered clients, like the client info text ("real name"), user
name, and hostname:
:<prefix> METADATA <target> <key> :<value>
It is distributed in the network, unknown <key> names are silently ignored
and passed on, too. This allows for further extensions.

If PredefChannelsOnly is enabled, and if someone tries to create
a channel which does not exist, then the error message is a 474.
The 474 Error message changed recently and does not match anymore:
'Cannot join channel (+b) -- You are banned'.
Changed the error message to numeric 403 'No such channel'.
Bug introduced by commit 9a82304a.

Now NICK commands are always generated using the prefix of the target
user, even when the nickname change has been initiated by some other
(pseudo) server or using the SVSNICK command. In this case, the prefix
of the initiator has been used, but this isn't compatible with clients
(at least weechat and irssi don't handle such NICK commands correctly).
|
|
The SVSNICK command allows other servers (and services on
"pseudo-servers") to forcefully change nicknames of remote users.
Syntax: ":<from> SVSNICK <oldnick> <newnick>"
The SVSNICK command itself doesn't change the nickname, but it becomes
forwarded to the server to which the user is connected to. And then this
server initiates the real nickname changing using regular NICK commands.
This allows to still run networks with old servers not supporting the
SVSNICK command, because SVSNICK commands for nicknames on such servers
are silently ignored and don't cause a desync of the network.

This reverts a not intentional code change and fixes the following compiler
warning message (tested with gcc 4.4.5):
irc-server.c: In function "IRC_SERVER":
irc-server.c:142: warning: suggest parentheses around operand of "!"
or change "&" to "&&" or "!" to "~"

Add randomly up to 15 seconds to the reconnect delay for outgoing server
links when the connection has been "short" and therefore the "ConnectRetry"
delay is being enforced.
This should make it even more unlikely that two servers deadlock each
other when both are trying to connect to the other one at the same time,
for example in test environments.
|
|
If two servers try to link each other, there was a time frame that
could result in one connection overwriting the other, e. g. the incoming
connection overwriting the status of the outgoing one. And this could
lead to all kind of weirdness (even crashes!) later on.
So now such incoming connections are dropped. But this most probably
prevents the two servers from linking until timing changes somehow
(network latency?) because each server drops the incoming connection of
the other one, so no connection survives in the end.
But this has to be addressed by an other patch ...

This is how ngIRCd up to release 19.2 behaved; "bug" introduced by commit
67e882, "configure.in: require autoconf 2.67 and automake 1.11", which
changed the "PACKAGE_NAME" to "ngIRCd"; so use "PACKAGE" which still is
the lowercase version for initializing syslog logging.
