* added ability to drop privilegesRainer Gerhards2008-11-261-3/+40
| | | | | | | Added $PrivDropToGroup, $PrivDropToUser, $PrivDropToGroupID, $PrivDropToUserID config directives to enable dropping privileges. This is an effort to provide a security enhancement. For the limits of this approach, see http://wiki.rsyslog.com/index.php/Security
* exprimental implementaiton of $PrivDropToUser directiveRainer Gerhards2008-11-191-4/+46
| | | | | | | | | | ... which permits to drop root privileges. This is not a completely secure way of dropping permissions, e.g. the group permissions need to be dropped, too. Also, there are several vulnerability Windows (see code comments). Finally, at least the imklog module on linux does not work when privileges are dropped. This code may still be a valuable addition, and so I have created an experimental branch so that people can check it out.

| | * added small regex check tool to repositoryRainer Gerhards2008-11-111-0/+72
| | | | | | | | | | | | | | | | | | This is intended for debugging and considered worth preserving. However, it has not (yet) been added to the build diag tools as it is not considered important enough.
* | | added configuration directive "HUPisRestart"Rainer Gerhards2008-10-232-47/+114

* | | moved bParseHostname and bIsParsed to msgFlagsRainer Gerhards2008-10-091-9/+12
| | | | | | | | | | | | | | | | | | This enables us to use more efficient calling conventions and also helps us keep the on-disk structure of a msg object more consistent in future releases.

* | | reordered imudp processing.Rainer Gerhards2008-10-081-6/+12
| | | | | | | | | | | | | | | | | | Message parsing is now done as part of main message queue worker processing (was part of the input thread) This should also improve performance, as potentially more work is done in parallel.
* | | "output" timestamp now taken from mesg's time generatedRainer Gerhards2008-10-071-12/+5
| | | | | | | | | | | | | | | | | | | | | This enhances performance and, as some have pointed out, is probably also more consistent with what users expect how the various output-timestamp related function should work. This commit needs some more testing.
* | | added $UDPServerTimeRequery optionRainer Gerhards2008-10-061-9/+30
| | | | | | | | | | | | | | | | | | | | | ...which enables to work with less acurate timestamps in favor of performance. This enables querying of the time only every n-th time if imudp is running in the tight receive loop (aka receiving messsages at a high rate)

| * | bugfix: potential race condition when adding messages to queueRainer Gerhards2008-09-181-4/+3
| | | | | | | | | | | | | | | | | | | | | There was a wrong order of mutex lock operations. It is hard to believe that really caused problems, but in theory it could and with threading we often see that theory becomes practice if something is only used long enough on a fast enough machine with enough CPUs ;)

* | consolidated time() calls in rule engineRainer Gerhards2008-09-161-3/+0
| | | | | | | | | | | | | | ... but did not manage to avoid doing at least one call. So this change introduced performance benefit only in a few non-common situations. Anyhow, it hopefully levels ground for better things to come.

Presence is depending on suport in each input module (else it is blank). - added system property "$myhostname", which contains the name of the local host as it knows itself.

* | enhanced configuration file error reporting and verificationRainer Gerhards2008-07-293-99/+191
| | | | | | | | | | | | | | | | | | | | | | | | - enhanced config file checking - no active actions are detected - added -N rsyslogd command line option for a config validation run (which does not execute actual syslogd code and does not interfere with a running instance) - somewhat improved emergency configuration. It is now also selected if the config contains no active actions - rsyslogd error messages are now reported to stderr by default. can be turned off by the new "$ErrorMessagesToStderr off" directive Thanks to HKS for suggesting these new features.
