This patch series converts the statically allocated password buffer in the
CLIENT structure into a dynamically (and only when needed) allocated buffer
which is referenced by the CONNECTION structure.
This a) saves memory for clients not using passwords at all and b) allows
for "arbitrarily" long passwords.
By Brett Smith (5) and Alexander Barton (2).
* 'move-connection-password' of git://arthur.barton.de/ngircd-alex:
Login_User(): use "conn" insted of calling Client_Conn(Client)
Free already saved password when storing a new one
Indentation and style fixes.
Connection password is not constant.
Implementation clean-ups.
Dynamically allocate memory for connection password.
Move client password from the Client to the Connection struct.
The "ServiceMask" variable in "Server" blocks now can handle more than
one mask using the new MatchCaseInsensitiveList() function.
This makes marking "service clients" much more specific, which is a
good thing per se, but which is the prerequisite for reasonably
blocking these nick names, too (see commit a6dd2e3 for details).
This patch introduces the new function Conf_NickIsBlocked() which checks
if a given nick name matches with the "service mask" of a configured server.
And Client_CheckNick() uses this information to deny such names for regular
IRC users.
So nick names intended for IRC services are more protected and can't be used
by regular users even when the "services pseudo-server" isn't connected to
the network.
But please note:
Up to now, there can be only one "ServiceMask" pattern per server, which
most probably blocks much more nick names than really required ...
So "ServiceMask" should allow more than one pattern which can be more
specific, and most probably it should be possible to block nick names in
the global server configuration as well.
Nick names introduced by other servers/services are never restricted.
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.
Implemented support for hashed hostnames for CloakHost. The admin can
use '%x' in both the CloakHost and CloakHostModeX setting. The config
option CloakHostModeX was renamed to CloakHostSalt. This salt is used
for both cloaking options.
CloakHostModeX can now contain '%x'. It will be replace by the hash of
the original client hostname. The new config option CloakHostModeXSalt
defines the salt for the hash function. When CloakHostModeXSalt is not
set a random salt will be generated after each server restart.
Spelling fix in defines.h
Don't try to establish an outgoing server link after DNS lookup when this
server re-connected on its own in the meantime.
In addition, log a warning message if we try to update the connection
index of an already connected server structure -- and ignore it.
Up to now, both behaviour could lead to a race when the remote server
connects to this daemon while it still prepares the outgoing connection:
- The local server prepares the new outgoing connection ...
- in the meantime the remote server becomes connected and registered.
- Now the new outgoing connection overwrites the (correct) socket handle,
- then the 2nd connection becomes disconnected: "already registered",
- and the 1st connection becomes unhandled ("gets lost") because the
configuration structure is reset because of the wrong socket handle.
This patch hopefully fixes all these problems.
Only alphanumeric characters are allowed in the user name, so ignore
all IDENT replies that would violate this rule and use the one supplied
by the USER command.
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:

* capabilities:
"multi-prefix" capability 2/2: adjust NAME and WHO handlers
"multi-prefix" capability 1/2: implement complete CAP infrastructure
IRC_Send_NAMES(): Code cleanup
New function Client_CapSet() in addition to Client_Cap{Add|Del}
"CAP REQ" starts capability negotiation and delays user registration
Correctly handle "CAP END", new client type CLIENT_WAITCAPEND
Implement core IRC capability handling and "CAP" command
New "login" source file
Introduce_Client() => Client_Introduce(), and move it to client.c
Now ngIRCd is able to handle "CAP LS", "CAP REQ", "CAP LIST", and
"CAP CLEAR" commands.
"multi-prefix" can be set/unset, but has no functionality - yet!
This fixes the following warning of clang:
/src/ngircd/lists.c:152:44:
warning: size argument in 'strlcpy' call appears to be size of the
source; expected the size of the destination [-Wstrlcpy-strlcat-size]
But it isn't a real problem, because the size of the source always is the
same than the size of the destination ...
