Triggering condition: multiple action + instances using ommysql. Thanks to Tomas Heinrich for reporting this + problem and providing an initial patch (which my solution is based on, + I need to add more code to clean the mess up). +- bugfix: rsyslog did not terminate when delayable inputs were blocked + due to unvailable sources. Fixes: + http://bugzilla.adiscon.com/show_bug.cgi?id=299 + Thanks to Marcin M for bringing up this problem and Andre Lorbach + for helping to reproduce and fix it. +--------------------------------------------------------------------------- +Version 5.9.6 [V5-BETA], 2012-04-12 +- added configuration directives to customize queue light delay marks +- permit size modifiers (k,m,g,...) in integer config parameters + Thanks to Jo Rhett for the suggestion. +- bugfix: hostname was not requeried on HUP + Thanks to Per Jessen for reporting this bug and Marius Tomaschewski for + his help in testing the fix. +- bugfix: imklog invalidly computed facility and severity + closes: http://bugzilla.adiscon.com/show_bug.cgi?id=313 +- bugfix: imptcp input name could not be set + config directive was accepted, but had no effect +- added configuration directive to disable octet-counted framing + for imtcp, directive is $InputTCPServerSupportOctetCountedFraming + for imptcp, directive is $InputPTCPServerSupportOctetCountedFraming +- added capability to use a local interface IP address as fromhost-ip for + locally originating messages. New directive $LocalHostIPIF +--------------------------------------------------------------------------- +Version 5.9.5 [V5-DEVEL], 2012-01-27 +- improved impstats subsystem, added many new counters +- enhanced module loader to not rely on PATH_MAX +- refactored imklog linux driver, now combined with BSD driver + The Linux driver no longer supports outdated kernel symbol resolution, + which was disabled by default for very long. Also overall cleanup, + resulting in much smaller code. Linux and BSD are now covered by a + single small driver. +- $IMUXSockRateLimitInterval DEFAULT CHANGED, was 5, now 0 + The new default turns off rate limiting. This was chosen as people + experienced problems with rate-limiting activated by default. Now it + needs an explicit opt-in by setting this parameter. + Thanks to Chris Gaffney for suggesting to make it opt-in; thanks to + many unnamed others who already had complained at the time Chris made + the suggestion ;-) +--------------------------------------------------------------------------- +Version 5.9.4 [V5-DEVEL], 2011-11-29 +- imuxsock: added capability to "annotate" messages with "trusted + information", which contains some properties obtained from the system + and as such sure to not be faked. This is inspired by the similiar idea + introduced in systemd. +- removed dependency on gcrypt for recently-enough GnuTLS + see: http://bugzilla.adiscon.com/show_bug.cgi?id=289 +- bugfix: imuxsock did no longer ignore message-provided timestamp, if + so configured (the *default*). Lead to no longer sub-second timestamps. + closes: http://bugzilla.adiscon.com/show_bug.cgi?id=281 +- bugfix: omfile returns fatal error code for things that go really wrong + previously, RS_RET_RESUME was returned, which lead to a loop inside the + rule engine as omfile could not really recover. +- bugfix: rsyslogd -v always said 64 atomics were not present + thanks to mono_matsuko for the patch +--------------------------------------------------------------------------- +Version 5.9.3 [V5-DEVEL], 2011-09-01 +- bugfix/security: off-by-two bug in legacy syslog parser, CVE-2011-3200 +- bugfix: mark message processing did not work correctly +- added capability to emit config error location info for warnings + otherwise, omusrmsg's warning about new config format was not + accompanied by problem location. +- bugfix: potential misadressing in property replacer +- bugfix: MSGID corruption in RFC5424 parser under some circumstances + closes: http://bugzilla.adiscon.com/show_bug.cgi?id=275 +- bugfix: The NUL-Byte for the syslogtag was not copied in MsgDup (msg.c) +--------------------------------------------------------------------------- +Version 5.9.2 [V5-DEVEL] (rgerhards), 2011-07-11 +- systemd support: set stdout/stderr to null - thx to Lennart for the patch +- added support for the ":omusrmsg:" syntax in configuring user messages +- added support for the ":omfile:" syntax in configuring user messages +--------------------------------------------------------------------------- +Version 5.9.1 [V5-DEVEL] (rgerhards), 2011-06-30 +- added support for obtaining timestamp for kernel message from message + If the kernel time-stamps messages, time is now take from that + timestamp instead of the system time when the message was read. This + provides much better accuracy. Thanks to Lennart Poettering for + suggesting this feature and his help during implementation. +- added support for obtaining timestamp from system for imuxsock + This permits to read the time a message was submitted to the system + log socket. Most importantly, this is provided in microsecond resolution. + So we are able to obtain high precision timestampis even for messages + that were - as is usual - not formatted with them. This also simplifies + things in regard to local time calculation in chroot environments. + Many thanks to Lennart Poettering for suggesting this feature, + providing some guidance on implementing it and coordinating getting the + necessary support into the Linux kernel. +- bugfix: timestamp was incorrectly calculated for timezones with minute + offset + closes: http://bugzilla.adiscon.com/show_bug.cgi?id=271 +- bugfix: problems in failover action handling + closes: http://bugzilla.adiscon.com/show_bug.cgi?id=270 + closes: http://bugzilla.adiscon.com/show_bug.cgi?id=254 +- bugfix: mutex was invalidly left unlocked during action processing + At least one case where this can occur is during thread shutdown, which + may be initiated by lower activity. In most cases, this is quite + unlikely to happen. However, if it does, data structures may be + corrupted which could lead to fatal failure and segfault. I detected + this via a testbench test, not a user report. But I assume that some + users may have had unreproducable aborts that were cause by this bug. +- bugfix: memory leak in imtcp & subsystems under some circumstances + This leak is tied to error conditions which lead to incorrect cleanup + of some data structures. [backport from v6] +- bugfix/improvement:$WorkDirectory now gracefully handles trailing slashes +--------------------------------------------------------------------------- +Version 5.9.0 [V5-DEVEL] (rgerhards), 2011-06-08 +- imfile: added $InputFileMaxLinesAtOnce directive +- enhanced imfile to support input batching +- added capability for imtcp and imptcp to activate keep-alive packets + at the socket layer. This has not been added to imttcp, as the latter is + only an experimental module, and one which did not prove to be useful. + reference: http://kb.monitorware.com/post20791.html +- added support to control KEEPALIVE settings in imptcp + this has not yet been added to imtcp, but could be done on request. +- $ActionName is now also used for naming of queues in impstats + as well as in the debug output +- bugfix: do not open files with full privileges, if privs will be dropped + This make the privilege drop code more bulletproof, but breaks Ubuntu's + work-around for log files created by external programs with the wrong + user and/or group. Note that it was long said that this "functionality" + would break once we go for serious privilege drop code, so hopefully + nobody still depends on it (and, if so, they lost...). +- bugfix: pipes not opened in full priv mode when privs are to be dropped +- this begins a new devel branch for v5 +- better handling of queue i/o errors in disk queues. This is kind of a + bugfix, but a very intrusive one, this it goes into the devel version + first. Right now, "file not found" is handled and leads to the new + emergency mode, in which disk action is stopped and the queue run + in direct mode. An error message is emited if this happens. +- added support for user-level PRI provided via systemd +- added new config directive $InputTCPFlowControl to select if tcp + received messages shall be flagged as light delayable or not. +- enhanced omhdfs to support batching mode. This permits to increase + performance, as we now call the HDFS API with much larger message + sizes and far more infrequently +- bugfix: failover did not work correctly if repeated msg reduction was on + affected directive was: $ActionExecOnlyWhenPreviousIsSuspended on + closes: http://bugzilla.adiscon.com/show_bug.cgi?id=236 +--------------------------------------------------------------------------- Version 5.8.11 [V5-stable] 2012-05-03 - bugfix: ommysql did not properly init/exit the mysql runtime library this could lead to segfaults.
