Up to now, ngIRCd silently ignored permission denied errors when trying
to enable a chroot setup: only the "not running chrooted" message became
logged later on.
This patch lets ngIRCd exit with a fatal error when the chroot can't
be enabled on startup -- this is the much safer bevahiour!
This fixes the following warning with gcc 4.6.3.:
irc-mode.c: In function "Channel_Mode":
irc-mode.c:947:26: error: "list" may be used uninitialized
in this function
irc-mode.c:884:25: error: "list" may be used uninitialized
in this function
(The variable has never been used uninitialized, so don't worry)
When
* building the ngircd Debian package (on Linux at least) and
* using the sbuild build system,
the command "ps -af" does not include the commands running inside the
sbuild system. Therefore, start-server.sh will report a fail as getpid.sh
cannot not find the ./T-ngircd1 just started although it's actually
running. This results in a funny build log ...
starting server 1 ... failure!
FAIL: start-server1
running connect-test ... ok.
PASS: connect-test
The self-test of getpid.sh however will likely succeed as it's happy if
it sees any process with "sh" somewhere in the name. Things go downhill
from there.
The confusing things are:
* The alternative cowbuilder/pbuilder does not have this problem.
* The alternative usage "ps ax" does fine.
So, as a quick hack, the patch attached adds another switch to getpid.sh.
Start "regular" logging not until the configuration file has been read in
and "SyslolgFacility" is set, and log all configuration errors using the
generic "daemon" facility.
So if there are no configuration errors, logging starts right after parsing
the configuration and we log the configuration file used _after_ reading it.
But this is no problem because every configuration error message includes
the configuration file name as well.
(The "double hello" has been introduced by commit 3641e51109)
Syslog logging has been initialized before reading the configuraton
file, so ngIRCd always used the default facility and ignored the
"SyslogFacility" configuration option.
Thanks to Patrik Schindler for reporting this issue!
This patch updates the limits for handling commands from a remote server:
- "<user count> / 5 + <min>" using "<min>=10" during normal operation,
- the above count multiplied with 5 while servers are syncing.
The intention is to a) make the limit dependent of the number of users
in the network (the more users, the more commands required to sync) and
b) to significantly rise this limit while servers are joining the network
to make the login and synchronization faster.
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.
The numeric RPL_WHOISHOST_MSG(378) returns the DNS hostname (if
available) and the IP address of a client in the WHOIS reply.
Only the user itself and local IRC operators get this numeric.
This allows to use "*!<user>@<host>" or "*!*@<host>" masks to reject
clients even before receiving PASS, NICK and USER commands and before
forking authentication child processes which reduces resource usage.
This allows a channel operator to define exception masks that allow users
to join the channel even when a "ban" would match and prevent them from
joining: the exception list (e) overrides the ban list (b).
