from bugzilla #105:
"ngircd-16 works great under openbsd4.7/i386, but it segfaults on
openbsd4.7/amd64."
Caused by missing function prototypes and the resulting truncation of
pointer to int.
Lets try to catch these bugs during compilation instead of SIGSEGV.
It is not possible to call Conn_Close() after Client_Destroy() has been
called, because Conn_Close wants to access the CLIENT structure which
then has been freed already.
Fix IRC_KILL to use Conn_Close() for local clients and Client_Destroy()
for remote clients only (and never both).
When we get there then the ssl handshake has failed, or
we could not create a ssl context because ssl library
initialization failed on startup.
Reflect that in the log message.
When ngIRCd restarts, all the connection counters are preserved now,
as well as the command counters for example.
It's unclear if resetting or not resetting is the "correct" behaviour,
but it's quite clear that the behaviour should be consistent for all the
counters ngIRCd uses ...
And initializing "WCounter", the global but temporary write counter,
is not necessarry at all: it is initialized (reset) before its use in
the command parser (see parse.c).
The RPL_STATSCONN numeric (250) displays information about the
highest simoultaneous connection count and the number of all
accepted connections since the daemon started up.
Used by ircd-Hybrid, Bahamut, and Unreal for example.
This patch enables ngIRCd to count the highest maximum simultaneous
connections and all the connections accepted since startup.
New functions:
- Conn_Count(): get current connections
- Conn_CountMax(): maximum simultaneous connections
- Conn_CountAccepted(): number of connections accepted
This solves warning messages of autoconf on e.g. FreeBSD 8:
configure: WARNING: netinet/ip.h: present but cannot be compiled
configure: WARNING: netinet/ip.h: check for missing prerequisite headers?
This fixes the following error when compiling on e.g. FreeBSD 6.x:
In file included from conn.c:40:
/usr/include/netinet/ip.h:160: error: syntax error before "n_long"
/usr/include/netinet/ip.h:163: error: syntax error before "n_long"
This patch fixes two warnings of gcc 4.4.3 when used with eglibc 2.11.1:
ngircd.c: In function ‘NGIRCd_Init’:
ngircd.c:801: warning: ignoring return value of ‘chdir’, declared with
attribute warn_unused_result
conn.c: In function ‘Simple_Message’:
conn.c:2041: warning: ignoring return value of ‘write’, declared with
attribute warn_unused_result
The first by checking the return code and an appropriate error message,
the second by "better" ignoring it (which is correct there!) ...
dpkg-shlibdeps: warning: dependency on libnsl.so.1 [..]
(they use none of its symbols).
As shown via commit 2b14234abc
(dpkg-shlibdeps: warning: dependency on libnsl.so.1) and the
following revert of that commit, we cannot simply drop
the AC_CHECK_LIB(nsl). Although -lnsl is indeed unneeded
when glibc is used, some platforms (e.g. Solaris) need it.
Use AC_SEARCH_LIBS instead to only link when the library exports
a particular symbol.
The WEBIRC command is used by some Web-to-IRC gateways to set the correct
user name and host name of users instead of their own.
Syntax: WEBIRC <password> <username> <hostname> <ip-address>
The <password> must be set using the new configuration variable "WebircPassword" in the [Global] section of ngircd.conf.
Please note that the <ip-address> is currently not used by ngIRCd (we don't store it in the CLIENT structure, only the resolved hostname).
Only clients using a SSL encrypted connection to the server are
allowed to join such a channel.
But please note three things:
a) already joined clients are not checked when setting this mode,
b) IRC operators are always allowed to join every channel, and
c) remote clients using a server not supporting this mode are not
checked either and therefore always allowed to join.
Now the numeric 004 correctly reports all the supported user and channel
modes (user modes "r" and "w" were missing), e. g.:
:a.irc.net 004 a a.irc.net ngircd-15 aiorsw biIklmnoPstv
Fix Apple Xcode warning "cc1: warning: -Wuninitialized is not supported
without -O" when using the "Debug" build target:
Detection of uninitialized automatic variable requires data flow analsys
that is only enabled during optimized compilation.
Print "SSLOptionVar =" instead of omitting the option when
running --configtest with ssl enabled.
This better matches the behaviour of other options, e.g. ChrootDir.
