Alexander Barton 25e56a5e83 Add some more casts in assert() statemens
This fixes the following warning messages of gcc 4.5.3 on Cygwin when
building with debug code enabled:

 ng_ipaddr.c: In function ‘ng_ipaddr_init’:
 ng_ipaddr.c:52:2: warning: comparison between signed and
                   unsigned integer expressions
 ng_ipaddr.c:53:20: warning: comparison between signed and
                    unsigned integer expressions

Alexander Barton 30796698a9 Only close "unrelated" sockets in forked child processes
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 ... :-(

Alexander Barton 160f5725a6 Do reverse lookups using the AF of the incoming connection
This fixes errors like this one:
  Address mismatch: 2001🔢abcd:1::1 != 192.168.1.1

Florian Westphal e4e1595bff 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.

Alexander Barton 596bc096b0 Make sourcecode compatible with ansi2knr again
This allows to compile ngIRCd using a pre-ANSI K&R C compiler again:
all source files are automatically converted by the included ansi2knr
program (of GNU automake/autoconf) before compiling them with the
K&R C compiler, but a few coding standards must be met.

Tested on Apple A/UX 3.x.
Regression testing on Linux and Mac OS X.

Alexander Barton 6ebb31ab35 Remove Proc_Kill(), use timeout to kill child processes
This avoids a race and potentionally killing the wrong process on
systems that use randomized process IDs; now the child itself is
responsible to exit in a timely manner using SIGALRM.

make it more generic thereby.

Alexander Barton 2d4ea28835 Resolver: Implement signal handler and catch TERM signal 2010-06-29 22:55:27 +02:00
Alexander Barton 54e67ea9ee New "module" proc.c/proc.h for generic process handling
The new "module" proc.c is used for functions dealing with child
processes. At the moment, it is only used by the asynchronous resolver.

All the functions already implemented habe been migrated from the
resolver code base, and the rest of the ngIRCd source code has been
adepted to the new namespace and calling conventions.

The goal is to develop "generic" process handling functions that can
be used for other purposes as well, e.g. running processes on client
connects etc.

Florian Westphal ed72bf4ceb resolve.c: fix valgrind 'uninitialized memory' warning
fix the following warning generated by valgrind if ipv6 is enabled:

Syscall param write(buf) points to uninitialised byte(s)
   at 0x4000982: (within /lib/ld-2.9.so)
   by 0x80681A8: Resolve_Name (resolve.c:477)
   by 0x805439F: Conn_Handler (conn.c:1658)
   by 0x804AA7C: main (ngircd.c:331)

The warning is because ng_ipaddr_t can be a union, and only the
necessary parts are initialised.  The callers know what part
of the union is valid, so this is not a bug.

Florian Westphal 1c7b9dbe93 remove unneeded LOG_DEBUG when not compiling with DEBUG support
when ngircd is build without DEBUG enabled, LOG_DEBUG messages
are always discarded.

To avoid the extra code, ngircd has a LogDebug() wrapper which
gets removed by the compiler when compiling without DEBUG defined.

Update a few functings which were using the
Log(LOG_DEBUG, .. interface directly without #ifdef DEBUG guards.

Alexander Barton 4c113d8850 New configuration option "NoIdent" to disable IDENT lookups

lookups enabled.
