Changelog

Version 4.1.1 [DEVEL] (rgerhards), 2008-11-26

• 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

• re-enabled imklog to compile on FreeBSD (brought in from beta)

Version 3.21.6 [DEVEL] (rgerhards), 2008-10-22

• consolidated time calls during msg object creation, improves performance
  and consistency

• bugfix: solved a segfault condition
• bugfix: subsecond time properties generated by imfile, imklog and
  internal messages could be slightly inconsistent

• added capability to support multiple module search pathes. Thank
  to Marius Tomaschewski for providing the patch.

• bugfix: im3195 did no longer compile
• merged-in fixes from stable and beta releases

Version 3.21.5 [DEVEL] (rgerhards), 2008-09-30

• performance optimization: unnecessary time() calls during message
  parsing removed – thanks to David Lang for his excellent performance
  analysis

• added new capability to property replacer: multiple immediately
  successive field delimiters are treated as a single one.
  Thanks to Zhuang Yuyao for the patch.

• added message property “inputname”, which contains the name of the
  input (module) that generated it. 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.

• imported a number of fixes and enhancements from the stable and
  devel branches, including a fix to a potential segfault on HUP
  when using UDP listners

• re-enabled gcc builtin atomic operations and added a proper
  ./configure check

• bugfix: potential race condition when adding messages to queue
  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 ;)

• cleaned up internal debug system code and made it behave better
  in regard to multi-threading

Version 3.21.4 [DEVEL] (rgerhards), 2008-09-04

• removed compile time fixed message size limit (was 2K), limit can now
  be set via $MaxMessageSize global config directive (finally gotten rid
  of MAXLINE ;))

• enhanced doc for $ActionExecOnlyEveryNthTimeTimeout
• integrated a number of patches from 3.18.4, namely
  • bugfix: order-of magnitude issue with base-10 size definitions
    in config file parser. Could lead to invalid sizes, constraints
    etc for e.g. queue files and any other object whose size was specified
    in base-10 entities. Did not apply to binary entities. Thanks to
    RB for finding this bug and providing a patch.

  • bugfix: action was not called when system time was set backwards
    (until the previous time was reached again). There are still some
    side-effects when time is rolled back (A time rollback is really a bad
    thing to do, ideally the OS should issue pseudo time (like NetWare did)
    when the user tries to roll back time). Thanks to varmojfekoj for this
    patch.

  • doc bugfix: rsyslog.conf man page improved and minor nit fixed
    thanks to Lukas Kuklinek for the patch.
