bugfix

——————————————————————————
Version 8.15.0 [v8-stable] 2015-12-15

• KSI Lib: Updated code to run with libksi 3.4.0.5
  Also libksi 3.4.0.x is required to build rsyslog if ksi support
  is enabled. New libpackages have been build as well.
• KSI utilities: Added option to ser publication url.
  Since libksi 3.4.0.x, there is no default publication url anymore.
  The publication url has to be set using the –publications-server
  Parameter, otherwise the ksi signature cannot be verified. UserID
  and UserKey can also be set by parameter now.
  Closes https://github.com/rsyslog/rsyslog/issues/581
• KSI Lib: Fixed wrong TLV container for KSI signatures from 0905 to 0906.
  closes https://github.com/rsyslog/rsyslog/issues/587
• KSI/GT Lib: Fixed multiple issues found using static analyzer
• performance improvement for configs with heavy use of JSON variables
  Depending on the config, this can be a very big gain in performance.
• added pmpanngfw: contributed module for translating Palo Alto Networks logs.
  see also: https://github.com/rsyslog/rsyslog/pull/573
  Thanks to Luigi Mori for the contribution.
• testbench: Changed valgrind option for imtcp-tls-basic-vg.sh
  For details see: https://github.com/rsyslog/rsyslog/pull/569
• pmciscoios: support for asterisk before timestamp added
  thanks to github user c0by for the patch
  see also: https://github.com/rsyslog/rsyslog/pull/583
• solr external output plugin much enhanced
  see also: https://github.com/rsyslog/rsyslog/pull/529
  Thanks to Radu Gheorghe for the patch.
• omrabbitmq: improvements
  thanks to Luigi Mori for the patch
  see also: https://github.com/rsyslog/rsyslog/pull/580
• add support for libfastjson (as a replacement for json-c)
• KSI utilities: somewhat improved error messages
  Thanks to Henri Lakk for the patch.
  see also: https://github.com/rsyslog/rsyslog/pull/588
• pmciscoios: support for some format variations
  Thanks to github user c0by for the patch
• support grok via new contributed module mmgrok
  Thanks to 饶琛琳 (github user chenryn) for the contribution.
• omkafka: new statistics counter “maxoutqsize”
  Thanks to 饶琛琳 (github user chenryn) for the contribution.
• improvments for 0mq modules:
  • omczmq – suspend / Retry handling – the output plugin can now recover
    from some error states due to issues with plugin startup or message sending
  • omczmq – refactored topic handling code for ZMQ_PUB output to be a little
    more efficient
  • omczmq – added ability to set a timeout for sends
  • omczmq – set topics can be in separate frame (default) or part of message
    frame (configurable)
  • omcmzq – code cleanup
  • imczmq – code cleanup
  • imczmq – fixed a couple of cases where vars could be used uninitialized
  • imczmq – ZMQ_ROUTER support
  • imczmq – Fix small memory leak from not freeing sockets  when done with them
  • allow creation of on demand ephemeral CurveZMQ certs for encryption.
    Clients may specify clientcertpath=”*” to indicate they want an on
    demand generated cert.

  Thanks to Brian Knox for the contributions.

• cleanup on code to unset a variable
  under extreme cases (very, very unlikely), the old code could also lead
  to errornous processing
• omelasticsearch: build on FreeBSD
  Thanks to github user c0by for the patch
• pmciscoios: fix some small issues clang static analyzer detected
• testbench: many improvements and some new tests
  note that there still is a number of tests which are somewhat racy
• overall code improvements thanks to clang static analyzer
• gnutls fix: Added possible fix for gnutls issue #575
  see also: https://github.com/rsyslog/rsyslog/issues/575
  Thanks to Charles Southerland for the patch
• bugfix omkafka: restore ability to build on all platforms
  Undo commit aea09800643343ab8b6aa205b0f10a4be676643b
  because that lead to build failures on various important platforms.
  This means it currently is not possible to configure the location
  of librdkafka, but that will affect far fewer people.
  closes: https://github.com/rsyslog/rsyslog/issues/596
• bugfix omkafka: fix potentially negative partition number
  Thanks to Tait Clarridge for providing a patch.
• bugfix: solve potential race in creation of additional action workers
  Under extreme circumstances, this could lead to segfault. Note that we
  detected this problem thanks to ASAN address sanitzier in combination
  with a very exterme testbench test. We do not think that this issue
  was ever reported in practice.
• bugfix: potential memory leak in config parsing
  Thanks to github user linmujia for the patch
• bugfix: small memory leak in loading template config
  This happened when a plugin was used inside the template. Then, the
  memory for the template name was never freed.
  Thanks to github user xushengping for the fix.
• bugfix: fix extra whitespace in property expansions
  Address off-by-one issues introduced in f3bd7a2 resulting in extra
  whitespace in property expansions
  Thanks to Matthew Gabeler-Lee for the patch.
• bugfix: mmfields leaked memory if very large messages were processed
  detected by clang static analyzer
• bugfix: mmfields could add garbagge data to field
  this happened when very large fields were to be processed.
  Thanks to Peter Portante for reporting this.
• bugfix: omhttpfs now also compiles with older json-c lib
• bugfix: memory leak in (contributed) module omhttpfs
  Thanks to git hub user c6226 for the patch.
• bugfix: parameter mismatch in error message for wrap() function
• bugfix: parameter mismatch in error message for random() function
• bugfix: divide by zero if max() function was provided zero
• bugfix: invalid mutex handling in omfile async write mode
  could lead to segfault, even though highly unlikely (caught by
  testbench on a single platform)
• bugfix: fix inconsistent number processing
  Unfortunately, previous versions of the rule engine tried to
  support oct and hex, but that wasn’t really the case.
  Everything based on JSON was just dec-converted. As this was/is
  the norm, we fix that inconsistency by always using dec.
  Luckly, oct and hex support was never documented and could
  probably only have been activated by constant numbers.
• bugfix: timezone() object: fix NULL pointer dereference
  This happened during startup when the offset or id parameter was not
  given. Could lead to a segfault at startup.
  Detected by clang static analyzer.
• bugfix omfile: memory addressing error if very long outchannel name used
  Thanks to github user c6226 for the patch.
