Changelog for 8.18.0 (v8-stable)

Version 8.18.0 [v8-stable] 2016-04-19

  • testbench: When running privdrop tests testbench tries to drop
    user to “rsyslog”, “syslog” or “daemon” when running as root and
    you don’t explict set RSYSLOG_TESTUSER environment variable.
    Make sure the unprivileged testuser can write into tests/ dir!
  • templates: add option to convert timestamps to UTC
  • omjournal: fix segfault (regression in 8.17.0)
  • imptcp: added AF_UNIX support
    Thanks to Nathan Brown for implementing this feature.
  • new template options
    • compressSpace
    • date-utc
  • redis: support for authentication
    Thanks to Manohar Ht for the patch
  • omkafka: makes kafka-producer on-HUP restart optional
    As of now, omkafka kills and re-creates kafka-producer on HUP. This
    is not always desirable. This change introduces an action param
    (reopenOnHup=”on|off”) which allows user to control re-cycling of
    It defaults to on (for backward compatibility). Off allows user to
    ignore HUP as far as kafka-producer is concerned.
    Thanks to Janmejay Singh for implementing this feature
  • imfile: new “FreshStartTail” input parameter
    Thanks to Curu Wong for implementing this.
  • omjournal: fix libfastjson API issues
    This module accessed private data members of libfastjson
  • ommongodb: fix json API issues
    This module accessed private data members of libfastjson
  • testbench improvements (more tests and more thourough tests)
    among others:

    • tests for omjournal added
    • tests for KSI subsystem
    • tests for priviledge drop statements
    • basic test for RELP with TLS
    • some previously disabled tests have been re-enabled
  • dynamic stats subsystem: a couple of smaller changes
    they also involve the format, which is slightly incompatible to
    previous version. As this was out only very recently (last version),
    we considered this as acceptable.
    Thanks to Janmejay Singh for developing this.
  • foreach loop: now also iterates over objects (not just arrays)
    Thanks to Janmejay Singh for developing this.
  • improvements to the CI environment
  • enhancement: queue subsystem is more robst in regard to some corruptions
    It is now detected if a .qi file states that the queue contains more
    records than there are actually inside the queue files. Previously this
    resulted in an emergency switch to direct mode, now the problem is only
    reported but processing continues.
  • enhancement: Allow rsyslog to bind UDP ports even w/out specific
    interface being up at the moment.
    Alternatively, rsyslog could be ordered after networking, however,
    that might have some negative side effects. Also IP_FREEBIND is
    recommended by systemd documentation.
    Thanks to Nirmoy Das and Marius Tomaschewski for the patch.
  • cleanup: removed no longer needed json-c compatibility layer
    as we now always use libfastjson, we do not need to support old
    versions of json-c (libfastjson was based on the newest json-c
    version at the time of the fork, which is the newest in regard
    to the compatibility layer)
  • new External plugin for sending metrics to SPM Monitoring SaaS
    Thanks to Radu Gheorghe for the patch.
  • bugfix imfile: fix memory corruption bug when appending @cee
    Thanks to Brian Knox for the patch.
  • bugfix: memory misallocation if position.from and is used
    a negative amount of memory is tried to be allocated if position.from
    is smaller than the buffer size (at least with json variables). This
    usually leads to a segfault.
  • bugfix: fix potential memleak in TCP allowed sender definition
    depending on circumstances, a very small leak could happen on each
    HUP. This was caused by an invalid macro definition which did not rule
    out side effects.
  • bugfix: $PrivDropToGroupID actually did a name lookup
    … instead of using the provided ID
  • bugfix: small memory leak in imfile
    Thanks to Tomas Heinrich for the patch.
  • bugfix: double free in jsonmesg template
    There has to be actual json data in the message (from mmjsonparse,
    mmnormalize, imjournal, …) to trigger the crash.
    Thanks to Tomas Heinrich for the patch.
  • bugfix: incorrect formatting of stats when CEE/Json format is used
    This lead to ill-formed json being generated
  • bugfix omfwd: new-style keepalive action parameters did not work
    due to being inconsistently spelled inside the code. Note that legacy
    parameters $keepalive… always worked
    see also:
    Thanks to Devin Christensen for alerting us and an analysis of the
    root cause.
  • bugfix: memory leaks in logctl utility
    Detected by clang static analyzer. Note that these leaks CAN happen in
    practice and may even be pretty large. This was probably never detected
    because the tool is not often used.
  • bugfix omrelp: fix segfault if no port action parameter was given
  • bugfix imtcp: Messages not terminated by a NL were discarded
    … upon connection termination.
    Thanks to Tomas Heinrich for the patch.

Changelog for 8.17.0 (v8-stable)

Version 8.17.0 [v8-stable] 2016-03-08

  • NEW REQUIREMENT: libfastjson
    see also:
  • new testbench requirement: faketime command line tool
    This is used to generate a controlled environment for time-based tests; if
    not available, tests will gracefully be skipped.
  • improve json variable performance
    We use libfastjson’s alternative hash function, which has been
    proven to be much faster than the default one (which stems
    back to libjson-c). This should bring an overall performance
    improvement for all operations involving variable processing.
  • new experimental feature: lookup table suport
    Note that at this time, this is an experimental feature which is not yet
    fully supported by the rsyslog team. It is introduced in order to gain
    more feedback and to make it available as early as possible because many
    people consider it useful.
    Thanks to Janmejay Singh for implementing this feature
  • new feature: dynamic statistics counters
    which may be changed during rule processing
    Thanks to Janmejay Singh for suggesting and implementing this feature
  • new contributed plugin: omampq1 for AMQP 1.0-compliant brokers
    Thanks to Ken Giusti for this module
  • new set of UTC-based $now family of variables ($now-utc, $year-utc, …)
  • simplified locking when accessing message and local variables
    this simlifies the code and slightly increases performance if such
    variables are heavily accessed.
  • new global parameter “debug.unloadModules”
    This permits to disable unloading of modules, e.g. to make valgrind
    reports more useful (without a need to recompile).
  • timestamp handling: guard against invalid dates
    We do not permit dates outside of the year 1970..2100
    interval. Note that network-receivers do already guard
    against this, so the new guard only guards against invalid
    system time.
  • imfile: add “trimlineoverbytes” input paramter
    Thanks to github user JindongChen for the patch.
  • ommongodb: add support for extended json format for dates
    Thanks to Florian Bücklers for the patch.
  • omjournal: add support for templates
    see also:
    Thanks to github user bobthemighty for the patch
  • imuxsock: add “ruleset” input parameter
  • testbench: framework improvement: configs can be included in test file
    they do no longer need to be in a separate file, which saves a bit
    of work when working with them. This is supported for simple tests with
    a single running rsyslog instance
    Thanks to Janmejay Singh for inspiring me with a similar method in
    liblognorm testbench.
  • imptcp: performance improvements
    Thanks to Janmejay Singh for implementing this improvement
  • made build compile (almost) without warnings
    still some warnings are suppressed where this is currently required
  • improve interface definition in some modules, e.g. mmanon, mmsequence
    This is more an internal cleanup and should have no actual affect to
    the end user.
  • solaris build: MAXHOSTNAMELEN properly detected
  • build system improvement: ability to detect old hiredis libs
    This permits to automatically build omhiredis on systems where the
    hiredis libs do not provide a pkgconfig file. Previsouly, this
    required manual configuration.
    Thanks to github user jaymell for the patch.
  • rsgtutil: dump mode improvements
    • auto-detect signature file type
    • ability to dump hash chains for log extraction files
  • build system: fix build issues with clang
    clang builds often failed with a missing external symbol
    “rpl_malloc”. This was caused by checks in,
    which checked for specific GNU semantics. As we do not need
    them (we never ask malloc for zero bytes), we can safely
    remove the macros.
    Note that we routinely run clang static analyer in CI and
    it also detects such calls as invalid.
  • bugfix: unixtimestamp date format was incorrectly computed
    The problem happened in leap year from March til then end
    of year and healed itself at the begining of the next year.
    During the problem period, the timestamp was 24 hours too low.
  • bugfix: date-ordinal date format was incorrectly computed
    same root cause aus for unixtimestamp and same triggering
    condition. During the affected perido, the ordinal was one
    too less.
  • bugfix: some race when shutting down input module threads
    this had little, if at all, effect on real deployments as it resulted
    in a small leak right before rsyslog termination. However, it caused
    trouble with the testbench (and other QA tools).
    Thanks to Peter Portante for the patch and both Peter and Janmejay
    Singh for helping to analyze what was going on.
  • bugfix tcpflood: did not handle connection drops correct in TLS case
    note that tcpflood is a testbench too. The bug caused some testbench
    instability, but had no effect on deplyments.
  • bugfix: abort if global parameter value was wrong
    If so, the abort happened during startup. Once started,
    all was stable.
  • bugfix omkafka: fix potential NULL pointer addressing
    this happened when the topic cache was full and an entry
    needed to be evicted
  • bugfix impstats: @cee cookie was prefixed to wrong fromat (json vs. cee)
    Thanks to Volker Fröhlich for the fix.
  • bugfix imfile: fix race during startup that could lead to some duplication
    If a to-be-monitored file was created after inotify was initialized
    but before startup was completed, the first chunk of data from this
    file could be duplicated. This should have happened very rarely in
    practice, but caused occasional testbench failures.
    see also:
  • bugfix: potential loss of single message at queue shutdown
    see also:
  • bugfix: potential deadlock with heavy variable access
    When making havy use of global, local and message variables, a deadlock
    could occur. While it is extremly unlikely to happen, we have at least
    seen one incarnation of this problem in practice.
  • bugfix ommysql: on some platforms, serverport parameter had no effect
    This was caused by an invalid code sequence which’s outcome depends on
    compiler settings.
  • bugfix omelasticsearch: invalid pointer dereference
    The actual practical impact is not clear. This came up when working
    on compiler warnings.
    Thanks to David Lang for the patch.
  • bugfix omhiredis: serverport config parameter did not reliably work
    depended on environment/compiler used to build
  • bugfix rsgtutil: -h command line option did not work
    Thanks to Henri Lakk for the patch.
  • bugfix lexer: hex numbers were not properly represented
    Thanks to Sam Hanes for the patch.
  • bugfix TLS syslog: intermittent errors while sending data
    Regression from commit 1394e0b. A symptom often seen was the message
    “unexpected GnuTLS error -50 in nsd_gtls.c:530”
  • bugfix imfile: abort on startup if no slash was present in file name param
    Thanks to Brian Knox for the patch.
  • bugfix rsgtutil: fixed abort when using short command line options
    Thanks to Henri Lakk
  • bugfix rsgtutil: invalid computation of log record extraction file
    This caused verification to fail because the hash chain was actually
    incorrect. Depended on the input data set.
  • bugfix build system: KSI components could only be build if in default path

Changelog for 8.16.0 (v8-stable)

Version 8.16.0 [v8-stable] 2016-01-26

  • rsgtutil: Added extraction support including loglines and hash chains.
    More details on how to extract loglines can be found in the rsgtutil
    manpage. See also:
  • clean up doAction output module interface
    We started with char * pointers, but used different types of pointers
    over time. This lead to alignment warnings. In practice, I think this
    should never cause any problems (at least there have been no reports
    in the 7 or so years we do this), but it is not clean. The interface is
    now cleaned up. We do this in a way that does not require modifications
    to modules that just use string parameters. For those with message
    parameters, have a look at e.g. mmutf8fix to see how easy the
    required change is.
  • new system properties for $NOW properties based on UTC
    This permits to express current system time in UTC.
    See also
  • impstats: support broken ElasticSearch JSON implementation
    ES 2.0 no longer supports valid JSON and disallows dots inside names.
    This adds a new “json-elasticsearch” format option which replaces
    those dots by the bang (“!”) character. So “discarded.full” becomes
    This is a workaroud. A method that will provide more control over
    replacements will be implemented some time in the future. For
    details, see below-quoted issue tracker.
  • omelasticsearch: craft better URLs
    Elasticsearch is confused by url’s ending in a bare ‘?’ or ‘&’. While
    this is valid, those are no longer produced.
    Thanks to Benno Evers for the patch.
  • imfile: add experimental “reopenOnTruncate” parameter
    Thanks to Matthew Wang for the patch.
  • bugfix imfile: proper handling of inotify initialization failure
    Thanks to Zachary Zhao for the patch.
  • bugfix imfile: potential segfault due to improper handling of ev var
    This occurs in inotify mode, only.
    Thanks to Zachary Zhao and Peter Portante for the patch.
  • bugfix imfile: potential segfault under heavey load.
    This occurs in inotify mode when using wildcards, only.
    The root cause is dropped IN_IGNOPRED inotify events which be dropped
    in circumstance of high input pressure and frequent rotation, and
    according to wikipeida, they can also be dropped in other conditions.
    Thanks to Zachary Zhao for the patch.
  • bugfix ommail: invalid handling of server response
    if that response was split into different read calls. Could lead to
    error-termination of send operation. Problem is pretty unlikely to
    occur in standard setups (requires slow connection to SMTP server).
    Thank to github user haixingood for the patch.
  • bugfix omelasticsearch: custom serverport was ignored on some platforms
    Thanks to Benno Evers for the patch.
  • bugfix: tarball did not include some testbench files
    Thanks to Thomas D. (whissi) for the patch.
  • bugfix: memory misadressing during config parsing string template
    This occurred if an (invalid) template option larger than 63 characters
    was given.
    Thanks to git hub user c6226 for the patch.
  • bugfix imzmq: memory leak
    Thanks to Jeremy Liang for the patch.
  • bugfix imzmq: memory leak
    Thanks to github user xushengping for the patch.
  • bugfix omzmq: memory leak
    Thanks to Jack Lin for the patch.
  • some code improvement and cleanup

Changelog for 8.15.0 (v8-stable)

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

  • KSI Lib: Updated code to run with libksi
    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.
  • KSI Lib: Fixed wrong TLV container for KSI signatures from 0905 to 0906.
  • 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:
    Thanks to Luigi Mori for the contribution.
  • testbench: Changed valgrind option for
    For details see:
  • pmciscoios: support for asterisk before timestamp added
    thanks to github user c0by for the patch
    see also:
  • solr external output plugin much enhanced
    see also:
    Thanks to Radu Gheorghe for the patch.
  • omrabbitmq: improvements
    thanks to Luigi Mori for the patch
    see also:
  • 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:
  • 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:
    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.
  • 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.

Changelog for 8.14.0 (v8-stable)

Version 8.14.0 [v8-stable] 2015-11-03

  • add property “rawmsg-after-pri”
  • bugfix: potential misadresseing in imfile
    Could happen when wildcards were used.
    see also
    see also
    Thanks to zhangdaoling for the bugfix.
  • bugfix: re_extract RainerScript function did not work
    Thanks to Janmejay Singh for the patch

Changelog for 8.12.0 (v8-stable)

Version 8.12.0 [v8-stable] 2015-08-11

  • Harmonize resetConfigVariables values and defaults
    see also
    Thanks to Tomas Heinrich for the patch.
  • GT/KSI: fix some issues in signature file format and add conversion tool
    The file format is incompatible to previous format, but tools have been upgraded to handle both and also an option been added to convert from old to new format.
  • bugfix: ommysql did not work when gnutls was enabled
    As it turned out, this was due to a check for GnuTLS functions with the side-effect that AC_CHECK_LIB, by default, adds the lib to LIBS, if there is no explicit action, what was the case here. So everything was now linked against GnuTLS, which in turn made ommysql fail.
    Thanks to Thomas D. (whissi) for the analysis of the ommysql/gnutls problem and Thomas Heinrich for pointing out that AC_CHECK_LIB might be the culprit.
  • bugfix omfile: potential memory leak on file close
    see also:
    Thanks to Robert Schiele for the patch.
  • bugfix omfile: potential race in dynafile detection/creation
    This could lead to a segfault.
    Thanks to Tomas Heinrich for the patch.
  • bugfix omfile: Fix race-condition detection in path-creation code
    The affected code is used to detect a race condition in between testing for the existence of a directory and creating it if it didn’t exist.  The variable tracking the number of attempts wasn’t reset for subsequent elements in the path, thus limiting the number of reattempts to one per the whole path, instead of one per each path element.
    This solution was provided by Martin Poole.
  • bugfix parser subsystem: potential misadressing in SanitizeMsg() could lead to a segfault
    Thanks to Tomas Heinrich for the patch.
  • imfile: files moved outside of directory are now (properly) handled
  • bugfix: imfile: segfault when using startmsg.regex if first log line doesn’t match
    Thanks to Ciprian Hacman for the patch.
  • bugfix imfile: file table was corrupted when on file deletion
    This could happen when a file that was statically configured (not via an wildcard) was deleted.
  • bugfix ompgsql: transaction were improperly handled
    Now transaction support is solidly disabled until we have enough requests to implement it again. Module still works fine in single insert mode.
  • bugfix mmjsonparse: memory leak if non-cee-json message is processed
    see also
    Thanks to Anton Matveenko for the patch
  • testbench: remove raciness from UDP based tests
  • testbench: added bash into all scripts makign it mandatory
  • bugfix testbench: Fixed problem building syslog_caller util when liblogging-stdlog is not available.
    Thanks to Louis Bouchard for the patch
  • bugfix rscryutil.1: Added fix checking for generate_man_pages condition
    Thanks to Radovan Sroka for the patch
  • bugfix freebsd console: \n (NL) is prepended with \r (CR) in console output on freebsd only. For more details see here:
    Thanks to AlexandreFenyo for the patch

Changelog for 8.11.0 (v8-stable)

Version 8.11.0 [v8-stable] 2015-06-30

  • new signature provider for Keyless Signature Infrastructure (KSI) added
  • build system: re-enable use of “make distcheck”
  • bugfix imfile: regex multiline mode ignored escapeLF option
    Thanks to Ciprian Hacman for reporting the problem
  • bugfix omkafka: fixed several concurrency issues, most of them related to dynamic topics.
    Thanks to Janmejay Singh for the patch.
  • bugfix: execonlywhenpreviousissuspended did not work correctly
    This especially caused problems when an action with this attribute was configured with an action queue.
  • bugfix core engine: ensured global variable atomicity
    This could lead to problems in RainerScript, as well as probably in other areas where global variables are used inside rsyslog. I wouldn’t outrule it could lead to segfaults.
    Thanks to Janmejay Singh for the patch.
  • bugfix imfile: segfault when using startmsg.regex because of empty log line
    Thanks to Ciprian Hacman for the patch.
  • bugfix: build problem on Solaris
    Thanks to Dagobert Michelsen for reporting this and getting us up to
    speed on the openCWS build farm.
  • bugfix: build system strndup was used even if not present now added compatibility function. This came up on Solaris builds.
    Thanks to Dagobert Michelsen for reporting the problem.


Changelog for 8.10.0 (v8-stable)

Version 8.10.0 [v8-stable] 2015-05-19

  • imfile: add capability to process multi-line messages based on regex input parameter “endmsg.regex” was added for that purpose. The new mode provides much more power in processing different multiline-formats.
  • pmrfc3164: add new parameters
    • “detect.yearAfterTimestamp”
      This supports timestamps as generated e.g. by some Aruba Networks equipment.
    • “permit.squareBracesInHostname”
      Permits to use “hostnames” in the form of “[]”; also seen in Aruba Networks equipment, but we strongly assume this can also happen in other cases, especially with IPv6.
  • supplementary groups are now set when dropping privileges
    Thanks to Zach Lisinski for the patch.
  • imfile: added brace glob expansion to wildcard
    Thanks to Zach Lisinski for the patch.
  • zmq: add the ability for zeromq input and outputs to advertise their presence on UDP via the zbeacon API.
    Thanks to Brian Knox for the contribution.
  • added omhttpfs: contributed module for writing to HDFS via HTTP
    Thanks to sskaje for the contribution.
  • Configure option “–disable-debug-symbols” added which is disabled per default. If you set the new option, configure won’t set the appropriate compiler flag to generate debug symbols anymore.
  • When building from git source we now require rst2man and yacc (or a replacement like bison).
    That isn’t any new requirement, we only added missing configure checks.
  • Configure option “–enable-generate-man-pages” is now disabled for non git source builds per default but enforced when building from git source.
  • mmpstrucdata: some code cleanup
    removed lots of early development debug outputs
  • bugfix imuxsock: fix a crash when setting a hostname
    Setting a hostname via the legacy directive would lead to a crash during shutdown caused by a double-free.
    Thanks to Tomas Heinrich for the patch.
  • bugfix: memory leak in mmpstrucdata
    Thanks to Grégoire Seux for reporting this issue.
  • bugfix (minor): default action name: assigned number was one off
    see also
    Thanks to Tomas Heinrich for the patch.
  • bugfix: memory leak in imfile
    A small leak happened each time a new file was monitored based on a wildcard. Depending on the rate of file creation, this could result in a serious memory leak.

Changelog for 8.9.0 (v8-stable)

Version 8.9.0 [v8-stable] 2015-04-07

  • omprog: add option “hup.forward” to forwards HUP to external plugins
    This was suggested by David Lang so that external plugins (and other
    programs) can also do HUP-specific processing. The default is not
    to forward HUP, so no change of behavior by default.
  • imuxsock: added capability to use regular parser chain
    Previously, this was a fixed format, that was known to be spoken on
    the system log socket. This also adds new parameters:

    • sysSock.useSpecialParser module parameter
    • sysSock.parseHostname module parameter
    • useSpecialParser input parameter
    • parseHostname input parameter
  • 0mq: improvements in input and output modules
    See module READMEs, part is to be considered experimental.
    Thanks to Brian Knox for the contribution.
  • imtcp: add support for ip based bind for imtcp -> param “address”
    Thanks to github user crackytsi for the patch.
  • bugfix: MsgDeserialize out of sync with MsgSerialize for StrucData
    This lead to failure of disk queue processing when structured data was
    present. Thanks to github user adrush for the fix.
  • bugfix imfile: partial data loss, especially in readMode != 0
  • bugfix: potential large memory consumption with failed actions
    see also
  • bugfix: omudpspoof: invalid default send template in RainerScript format
    The file format template was used, which obviously does not work for
    forwarding. Thanks to Christopher Racky for alerting us.
  • bugfix: size-based legacy config statements did not work properly
    on some platforms, they were incorrectly handled, resulting in all
    sorts of “interesting” effects (up to segfault on startup)
  • build system: added option –without-valgrind-testbench
    … which provides the capability to either enforce or turn off
    valgrind use inside the testbench. Thanks to whissi for the patch.
  • rsyslogd: fix misleading typos in error messages
    Thanks to Ansgar Püster for the fixes.

Changelog for 8.8.0 (v8-stable)

Version 8.8.0 [v8-stable] 2015-02-24

  • omkafka: add support for dynamic topics and auto partitioning
    Thanks to Tait Clarridge for the patches.
  • imtcp/imptcp: support for broken Cisco ASA TCP syslog framing
  • omfwd: more detailled error messages in case of UDP send error
  • TLS syslog: enable capability to turn on GnuTLS debug logging
    This provides better diagnostics in hard-to-diagnose cases,
    especially when GnuTLS is extra-picky about certificates.
  • bugfix: $AbortOnUncleanConfig did not work
  • improve rsyslogd -v output and error message with meta information
    version number is now contained in error message and build platform in
    version output. This helps to gets rid of the usual “which version”
    question on mailing list, support forums, etc…
  • bugfix imtcp: octet-counted framing cannot be turned off
  • bugfix: build problems on Illuminos
    Thanks to Andrew Stormont for the patch
  • bugfix: invalid data size for iMaxLine global property
    It was defined as int, but inside the config system it was declared as
    size type, which uses int64_t. With legacy config statements, this could
    lead to misadressing, which usually meant the another config variable was
    overwritten (depending on memory layout).
  • bugfix: negative values for maxMessageSize global parameter were permitted
