This partially reverts commit b130b35f4, "Update #include's: remove
unused and add missing ones", but fixes the following compiler and
analyzer warnings of Apple Xcode 5:
"Semantic issue: No previous prototype for function 'yyy'"
The "deheader" tool (<http://www.catb.org/~esr/deheader/>) has been
used to find unused #include directives as well as missing ones.
Tested on:
- A/UX 3.1.1
- ArchLinux (2014-03-17)
- Debian GNU/Hurd
- Debian GNU/Linux 6.0.9
- Debian GNU/Linux 7.4
- Fedora 20
- FreeBSD 9.2
- OpenBSD 4.8
- OpenBSD 5.1
- OS X 10.9
- Solaris 11
When DNS lookups are disabled, don't set the hostname received by the
WEBIRC command, but use the IP address instead.
Reported by Toni Spets <toni.spets@iki.fi>, thanks!
Closes bug #167.
The old local function Kill_Nick() in irc.c has been an ugly hack. This
patch implements a generic function for killing clients.
Adjust all callers of Kill_Nick() and respect the return code!
This patch introduces a new field in the CLIENT structure, "ipa_text",
which points to an optional textual representation of the client IP
address (or NULL) which can be used to store the "real" IP address
information of a client using the "WEBIRC" protocol.
Without this patch, ngIRCd ignored the <ip-address> paramater ...
In addition, the functions Client_SetIPAText() and Client_IPAText()
have been introduced to set and get the textual representation of the
client IP address.
Client_IPAText() can be used even when no "IP address text" has been
set before, it then returns the real IP address of the connection.
Closes bug #159.
This function is used to send "error messages", including numerics,
back to clients and to automatically enforce a 2 second penalty. With
this patch, all error results enforces a delay for the client.
All callers of IRC_WriteStrClient(ERR_xxx) have been converted.
Please note that this patch prolongs the time "make check" needs
to complete its tests, because of lots of new enforced penalties ...
This patch changes the handlers of the "PASS", "NICK", "USER",
and "SERVICE" commands to enforce a 2 second penalty when an error
like "need more/other parameters" occurs.
More functions should follow, I think ...
The "@" character isn't allowed in IRC usernames, because it is the
separator between user name and hostname in IRC masks:
<nickname>!<username>@<hostname>
This patch accepts user names including "@" characters, saves the
unmodified name for authentication but stores only the part in front
of the "@" character as "IRC user name". And the latter is how
ircd2.11, Bahamut, and irc-seven behave as well.
Closes bug #155.
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 ...
This fixes a few warnings of this type:
XXX.c: In function 'AAA':
XXX.c:YY: warning: array subscription has type 'char'
Tested on NetBSD 5.0.2 with gcc 4.1.3.
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 is a relatively naive implementation, basically doing the bare minimum
necessary to make the switchover go. Subsequent commits can focus on
improving the implementation.
Only alphanumeric characters are allowed in the user name, so terminate
the connection if any "strage" characters have been supplied by the user.
This is how other IRC daemons (like ircd2.11 and ircd-seven) behave ...
This fixes the following warnings with GCC 4.4.5 on Linux:
irc-login.c: In function ‘IRC_PASS’:
irc-login.c:92: warning: implicit declaration of function ‘strlen’
irc-login.c:92: warning: incompatible implicit declaration of built-in function ‘strlen’
irc-login.c:113: warning: incompatible implicit declaration of built-in function ‘strlen’
irc-login.c:129: warning: implicit declaration of function ‘strchr’
irc-login.c:129: warning: incompatible implicit declaration of built-in function ‘strchr’
irc-login.c:133: warning: implicit declaration of function ‘strcmp’

irc-login.c:556: warning: incompatible implicit declaration of built-in function ‘strchr’
login.c: In function ‘Login_User’:
login.c:131: warning: implicit declaration of function ‘strcmp’
Rename Hello_User[_PostAuth] to Login_User[_PostAuth] and move it to the
new login.c; and move cb_Read_Auth_Result(), too. This will enable further
code to easily call Login_User() when required.
At the end of sending all "state" to the remote server, a PING command
is sent to request a PONG reply. Until then, no "regual" PING was sent,
so Conn_LastPing(<connection>) is null and now becomes non-null in the
PONG command handler.
So the servers are still synchronizing when Conn_LastPing(<connection>)
is 0, which could easily be tested.
When "PAMIsOptional" is set, clients not sending a password are still
allowed to connect: they won't become "identified" and keep the "~"
character prepended to their supplied user name.
This fixes the problem that ngIRCd can't do any IDENT lookups because
of the socket has already been closed in the child process.
The bug has been introduced starting with ngIRCd 17 ... :-(
(commit ID 6ebb31ab35)
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 ...
This fixes the followin GCC warning on modern Linux systems as well:
irc-login.c: In function ‘Hello_User’:
irc-login.c:876: warning: ignoring return value of ‘write’,
declared with attribute warn_unused_result
