This is primarily a fix for the invalid + framing used in Juniper's NetScreen products. Credit to forum user + Arv for suggesting this solution. +- added $InputTCPServerInputName property, which enables a name to be + specified that will be available during message processing in the + inputname property. This is considered useful for logic that treats + messages differently depending on which input received them. +- added $PreserveFQDN config file directive + Enables to use FQDNs in sender names where the legacy default + would have stripped the domain part. + Thanks to BlinkMind, Inc. http://www.blinkmind.com for sponsoring this + development. +- bugfix: imudp went into an endless loop under some circumstances + (but could also leave it under some other circumstances...) + Thanks to David Lang and speedfox for reporting this issue. +--------------------------------------------------------------------------- +Version 4.1.2 [DEVEL] (rgerhards), 2008-12-04 +- bugfix: code did not compile without zlib +- security bugfix: $AllowedSender was not honored, all senders were + permitted instead (see http://www.rsyslog.com/Article322.phtml) +- security fix: imudp emitted a message when a non-permitted sender + tried to send a message to it. This behaviour is operator-configurable. + If enabled, a message was emitted each time. That way an attacker could + effectively fill the disk via this facility. The message is now + emitted only once in a minute (this currently is a hard-coded limit, + if someone comes up with a good reason to make it configurable, we + will probably do that). +- doc bugfix: typo in v3 compatibility document directive syntax + thanks to Andrej for reporting +- imported other changes from 3.21.8 and 3.20.1 (see there) +--------------------------------------------------------------------------- +Version 4.1.1 [DEVEL] (rgerhards), 2008-11-26 +- added $PrivDropToGroup, $PrivDropToUser, $PrivDropToGroupID, + $PrivDropToUserID config directives to enable dropping privileges. + This is an effort to provide a security enhancement. For the limits of this + approach, see http://wiki.rsyslog.com/index.php/Security +- re-enabled imklog to compile on FreeBSD (brought in from beta) +--------------------------------------------------------------------------- +Version 4.1.0 [DEVEL] (rgerhards), 2008-11-18 + +********************************* WARNING ********************************* +This version has a slightly different on-disk format for message entries. +As a consequence, old queue files being read by this version may have +an invalid output timestamp, which could result to some malfunction inside +the output driver. It is recommended to drain queues with the previous +version before switching to this one. +********************************* WARNING ********************************* + +- greatly enhanced performance when compared to v3. +- added configuration directive "HUPisRestart" which enables to configure + HUP to be either a full restart or "just" a leightweight way to + close open files. +- enhanced legacy syslog parser to detect year if part of the timestamp + the format is based on what Cisco devices seem to emit. +- added a setting "$OptimizeForUniprocessor" to enable users to turn off + pthread_yield calls which are counter-productive on multiprocessor + machines (but have been shown to be useful on uniprocessors) +- reordered imudp processing. 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. +- bugfix: compressed syslog messages could be slightly mis-uncompressed + if the last byte of the compressed record was a NUL +- added $UDPServerTimeRequery option 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) +- doc bugfix: queue doc had wrong parameter name for setting controlling + worker thread shutdown period +- restructured rsyslog.conf documentation +- bugfix: memory leak in ompgsql + Thanks to Ken for providing the patch +--------------------------------------------------------------------------- Version 3.21.11 [BETA] (rgerhards), 2009-0?-?? - build system improvements contributed by Michael Biebl - thx! --------------------------------------------------------------------------- @@ -40,9 +136,12 @@ Version 3.21.6 [DEVEL] (rgerhards), 2008-10-22 - bugfix: solved a segfault condition - bugfix: subsecond time properties generated by imfile, imklog and internal messages could be slightly inconsistent +- bugfix: (potentially big) memory leak on HUP if queues could not be + drained before timeout - thanks to David Lang for pointing this out - added capability to support multiple module search pathes.
