Version 8.1.5 [devel] 2014-01-??
- imfile now supports inotify (but must be explicitely turned on)
- imfile no longer has a limit on number of monitored files
---------------------------------------------------------------------------
Version 8.1.4 [devel] 2014-01-10
- add exec_template() RainerScript function
- imrelp: support for TCP KEEPALIVE added
- bumped librelp dependency to 1.2.2 to support new KEEPALIVE feature
- Add directives for numerically specifying GIDs/UIDs
The already present directives (FileOwner, FileGroup, DirOwner,
DirGroup) translate names to numerical IDs, which depends on the user
information being available during rsyslog's startup. This can fail if
the information is obtained over a network or from a service such as
SSSD. The new directives provide a way to specify the numerical IDs
directly and bypass the lookup.
Thanks to Tomas Heinrich for the patch.
- bugfix: action commitTransaction() processing did not properly handle
suspended actions
- bugfix: omelasticsearch fail.es stats counter was improperly maitained
---------------------------------------------------------------------------
Version 8.1.3 [devel] 2013-12-06
THIS VERSION CAN BE CONSIDERED A "NORMAL" DEVEL RELEASE. It's no longer
highly experimental. This assertion is based on real-world feedback.
- changes to the strgen module interface
- new output module interface for transactional modules
- performance improvements
* reduced number of malloc/frees due to further changes to the
output module interface
* reduced number of malloc/frees during string template processing
We now re-use once allocated string template memory for as long
as the worker thread exists. This saves us from doing new memory
allocs (and their free counterpart) when the next message is
processed. The drawback is that the cache always is the size of
the so-far largest message processed. This is not considered a
problem, as in any case a single messages' memory footprint should
be far lower than that of a whole set of messages (especially on
busy servers).
* used variable qualifiers (const, __restrict__) to hopefully help
the compiler generate somewhat faster code
- failed action detection more precisely for a number of actions
If an action uses string parameter passing but is non-transactional
it can be executed immediately, giving a quicker indicatio of
action failure.
- bugfix: limiting queue disk space did not work properly
* queue.maxdiskspace actually initializes queue.maxfilesize
* total size of queue files was not checked against
queue.maxdiskspace for disk assisted queues.
Thanks to Karol Jurak for the patch.
---------------------------------------------------------------------------
Version 8.1.2 [experimental] 2013-11-28
- support for liblognorm1 added - results in performance improvements
Thanks to Pavel Levshin for his work in this regard.
- support for jemalloc added via --enable-jemalloc
Thanks to Pavel Levshin for suggesting jemalloc
Note that build system is experimental at this stage.
- queue defaults have changed
* high water mark is now dynamically 90% of queue size
* low water makr is now dynamically 70% of queue size
* queue.discardMark is now dynamically 98% of queue size
* queue.workerThreadMinimumMessage set to queue.size / num workers
For queues with very low queue.maxSize (< 100), "emergency" defaults
will be used.
- bugfix: disk queues created files in wrong working directory
if the $WorkDirectory was changed multiple times, all queues only
used the last value set.
- bugfix: legacy directive $ActionQueueWorkerThreads was not honored
- bugfix: mmrfc5424addhmac: "key" parameter was not properly processed
---------------------------------------------------------------------------
Version 8.1.1 [experimental] 2013-11-19
- bugfix: STOP/discard(~) was mostly NOT honored
This lead to execution of config code that was not meant to be executed.
- bugfix: memory leak on worker thread termination
- bugfix: potential segfault in omfile under heavy load
Thanks to Pavel Levshin for alerting us.
- bugfix: mmsequence: instance mode did not work
Thanks to Pavel Levshin for the patch
- bugfix: segfault on startup when certain script constructs are used
e.g. "if not $msg ..."
- omhiredis: now supports v8 output module interface and works again
Thanks to Pavel Levshin for the patch
- mmaudit: now supports v8 output module interface and work again
- bugfix: potential abort on startup in debug mode
This depends on template type being used. The root cause was a
non-necessary debug output, which were at the wrong spot (leftover from
initial testing).
Thanks to Pavel Levshin for alerting us and providing a patch
proposal.
---------------------------------------------------------------------------
Version 8.1.0 [experimental] 2013-11-15
- rewritten core engine for higher performance and new features
In detail:
* completely rewritten rule execution engine
* completely changed output module interface
* remodelled output module interface
* enabled important output modules to support full concurrent
operation
The core engine has been considerably changed and must be considered
experimental at this stage. Note that it does not yet include all
features planned for v8, but is close to this goal. In theory, the
engine should perform much better, especially on complex configurations
and busy servers. Most importantly, actions instances can now be called
concurrently from worker threads and many important output modules
support multiple concurrent action instances natively.
- module omruleset is no longer enabled by default.
Note that it has been deprecated in v7 and been replaced by the "call"
statement. Also, it can still be build without problems, the option must
just explicitely be given.
---------------------------------------------------------------------------
Version 7.5.8 [v7-release candidate] 2014-01-09
- add exec_template() RainerScript function
- add debug.onShutdown and debug.logFile global paramters
These enebale the new "debug on shutdown" mode, which can be used to
track hard to find problems that occur during system shutdown.
- Add directives for numerically specifying GIDs/UIDs
The already present directives (FileOwner, FileGroup, DirOwner,
DirGroup) translate names to numerical IDs, which depends on the user
information being available during rsyslog's startup. This can fail if
the information is obtained over a network or from a service such as
SSSD. The new directives provide a way to specify the numerical IDs
directly and bypass the lookup.
Thanks to Tomas Heinrich for the patch.
- actions now report if they suspend and resume themselves
this is by default on and controllable by the action.reportSuspension
global parameter
- bugfix: omelasticsearch fail.es stats counter was improperly maintained
- bugfix: mmrfc5424addhmac: "key" parameter was not properly processed
- add new impstats action counters:
* suspended
* suspended.duration
* resumed
---------------------------------------------------------------------------
Version 7.5.7 [v7-devel] 2013-11-25
- queue defaults have changed
* high water mark is now dynamically 90% of queue size
* low water makr is now dynamically 70% of queue size
* queue.discardMark is now dynamically 98% of queue size
* queue.workerThreadMinimumMessage set to queue.size / num workers
For queues with very low queue.maxSize (< 100), "emergency" defaults
will be used.
- worker thread pool handling has been improved
Among others, permits pool to actually shrink (was quite hard with
previous implementation. This will also improve performance and/or
lower system overhead on busy systems.
Thanks to Pavel Levshin for the enhancement.
- bugfix: mmpstrucdata generated inaccessible properties
- bugfix: RainerScript optimizer did not optimize PRI filters
things like "if $syslogfacility-text == "local3"" were not converted
to PRIFILT. This was a regression introduced in 7.5.6.
- bugfix: legacy directive $ActionQueueWorkerThreads was not honored
- bugfix: segfault on startup when certain script constructs are used
e.g. "if not $msg ..."
- bugfix: ommysql lost configfile/section parameters after first close
This means that when a connection was broken, it was probably
re-instantiated with different parameters than configured.
- bugfix: regression in template processing with subtrees in templates
Thanks to Pavel Levshin for the fix
- bugfix: regular worker threads are not properly (re)started if DA
mode is active.
This occurs only under rare conditions, but definitely is a bug that
needed to be addressed. It probably is present since version 4.
Note that this patch has not been applied to v7.4-stable, as it
is very unlikely to happen and the fix itself has some regression
potential (the fix looks very solid, but it addresses a core component).
Thanks to Pavel Levshin for the fix
- now emit warning message if om with msg passing mode uses action queue
These can modify the message, and this causes races.
- bugfix: $SystemLogUseSysTimeStamp/$SystemLogUsePIDFromSystem did not work
Thanks to Tomas Heinrich for the patch.
---------------------------------------------------------------------------
Version 7.5.6 [devel] 2013-10-29
- impstats: add capability to bind to a ruleset
- improved performance of RainerScript variable access
by refactoring the whole body of variable handling code. This also
solves some of the anomalies experienced in some versions of rsyslog.
All variable types are now handled in unified code, including
access via templates.
- RainerScript: make use of 64 bit for numbers where available
Thanks to Pavel Levshin for enhancement.
- slight performance optimization if GCC is used
We give branch prediction hints for the frequent RETiRet macro which is
used for error handling. Some slight performance gain is to be expected
from that.
- removed global variable support
The original idea was not well thought out and global variables, as
implemented, worked far different from what anybody would expect. As
such, we consider the current approach as an experiment that did not
work out and opt to removing it, clearing the way for a better future
solution. Note: global vars were introduced in 7.5.3 on Sept, 11th 2013.
- new module mmsequence, primarily used for action load balancing
Thanks to Pavel Levshin for contributing this module.
- bugfix: unset statement always worked on message var, even if local
var was given
- imudp: support for binding to ruleset added
- bugfix: segfault if variable was assigned to non-container subtree
Thanks to Pavel Levshin for the fix
- bugfix: imuxsock did not suport addtl sockets if syssock was disabled
Thanks to Pavel Levshin for the fix
- bugfix: running imupd on multiple threads lead to segfault if recvmmsg
is available
- bugfix: imudp when using recvmmsg could report wrong sender IP
- bugfix: segfault if re_extract() function was used and no match found
- bugfix: omelasticsearch did not compile on platforms without atomic
instructions
- bugfix: potential misadressing on startup if property-filter was used
This could happen if the property name was longer than 127 chars, a case
that would not happen in practice.
- bugfix: invalid property filter was not properly disabled in ruleset
Note: the cosmetic memory leak introduced with that patch in 7.4.5 is
now also fixed.
- imported bugfixes from 7.4.6 stable release
---------------------------------------------------------------------------
Version 7.5.5 [devel] 2013-10-16
- imfile: permit to monitor an unlimited number of files
- imptcp: add "defaultTZ" input parameter
- imudp: support for multiple receiver threads added
- imudp: add "dfltTZ" input config parameter
- bugfix: memory leak in mmnormalize
- bugfix: mmutf8fix did not properly handle invalid UTF-8 at END of message
if the very last character sequence was too long, this was not detected
Thanks to Risto Vaarandi for reporting this problem.
- mmanon: removed the check for specific "terminator characters" after
last octet. As it turned out, this didn't work in practice as there
was an enormous set of potential terminator chars -- so removing
them was the best thing to do. Note that this may change behaviour of
existing installations. Yet, we still consider this an important
bugfix, that should be applied to the stable branch.
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=477
Thanks to Muri Cicanor for initiating the discussion
- now requires libestr 0.1.7 as early versions had a nasty bug in
string comparisons
- bugfix: mmanon did not detect all IP addresses in rewrite mode
The problem occured if two IPs were close to each other and the first one
was shrunk.
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=485
Thanks to micah-at-riseup.net for reporting this bug
- bugfix: mmanon sometimes used invalid replacement char in simple mode
depending on configuration sequence, the replacement character was set
to 's' instead of the correct value. Most importantly, it was set to
's' if simple mode was selected and no replacement char set.
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=484
Thanks to micah-at-riseup.net for reporting this bug
- bugfix: memory leak in mmnormalize
- bugfix: array-based ==/!= comparisions lead to invalid results
This was a regression introduced in 7.3.5 bei the PRI optimizer
---------------------------------------------------------------------------
Version 7.5.4 [devel] 2013-10-07
- mmpstrucdata: new module to parse RFC5424 structured data into json
message properties
- change main/ruleset queue defaults to be more enterprise-like
new defaults are queue.size 100,000 max workers 2, worker
activation after 40,000 msgs are queued, batch size 256. These settings
are much more useful for enterprises and will not hurt low-end systems
that much. This is part of our re-focus on enterprise needs.
- omfwd: new action parameter "maxErrorMessages" added
- omfile: new module parameters to set action defaults added
* dirCreateMode
* fileCreateMode
- mmutf8fix: new module to fix invalid UTF-8 sequences
- imuxsock: handle unlimited number of additional listen sockets
- doc: improve usability by linking to relevant web ressources
The idea is to enable users to quickly find additional information,
samples, HOWTOs and the like on the main site.
At the same time, (very) slightly remove memory footprint when
few listeners are monitored.
- bugfix: omfwd parameter streamdrivermmode was not properly handled
it was always overwritten by whatever value was set via the
legacy directive $ActionSendStreamDriverMode
- imtcp: add streamdriver.name module parameter
permits overriding the system default stream driver (gtls, ptcp)
- bugfix: build system: libgcrypt.h needed even if libgrcypt was disabled
Thanks to Jonny Törnbom for reporting this problem
- imported bugfixes from 7.4.4
---------------------------------------------------------------------------
Version 7.5.3 [devel] 2013-09-11
- imfile: support for escaping LF characters added
embedded LF in syslog messages cause a lot of trouble. imfile now has
the capability to escape them to "#012" (just like the regular control
character escape option). This requires new-style input statements to be
used. If legacy configuration statements are used, LF escaping is always
turned off to preserve compatibility.
NOTE: if input() statements were already used, there is a CHANGE OF
BEHAVIOUR: starting with this version, escaping is enabled by
default. So if you do not want it, you need to add
escapeLF="off"
to the input statement. Given the trouble LFs cause and the fact
that the majority of installations still use legacy config, we
considered this behaviour change acceptable and useful.
see also: http://blog.gerhards.net/2013/09/imfile-multi-line-messages.html
- add support for global and local variables
- bugfix: queue file size was not correctly processed
this could lead to using one queue file per message for sizes >2GiB
Thanks to Tomas Heinrich for the patch.
- add main_queue() configuration object to configure main message queue
- bugfix: stream compression in imptcp caused timestamp to be corrupted
- imudp: add ability to specify SO_RCVBUF size (rcvbufSize parameter)
- imudp: use inputname for statistics, if configured
- impstats: add process resource usage counters [via getrusage()]
- impstats: add paramter "resetCounters" to report delta values
possible for most, but not all, counters. See doc for details.
- librelp 1.2.0 is now required
- make use of new librelp generic error reporting facility
This leads to more error messages being passed to the user and
thus simplified troubleshooting.
- bugfix: very small memory leak in imrelp
more or less cosmetic, a single memory block was not freed, but this
only happens immediately before termination (when the OS automatically
frees all memory). Still an annoyance e.g. in valgrind.
- fix compile problem in debug build
- imported fixes from 7.4.4
---------------------------------------------------------------------------
Version 7.5.2 [devel] 2013-07-04
- librelp 1.1.4 is now required
We use API extensions for better error reporting and higher performance.
- omrelp: use transactional mode to make imrelp emit bulk sends
- omrelp: add "windowSize" parameter to set custom RELP window size
- bugfix: double-free in omelasticsearch

---------------------------------------------------------------------------
Version 7.5.1 [devel] 2013-06-26
- librelp 1.1.3 is required - older versions can lead to a segfault
- add mmfields, which among others supports easy parsing of CEF messages
- omrelp:
* new parameter "compression.prioritystring" to control encryption
parameters used by GnuTLS
- imrelp:
* new parameter "compression.dhbits" to control the number of
bits being used for Diffie-Hellman key generation
* new parameter "compression.prioritystring" to control encryption
parameters used by GnuTLS
* support for impstats added
* support for setting permitted peers (client authentication) added
* bugfix: potential segfault at startup on invalid config parameters
- imjournal: imported patches from 7.4.1
- omprog: add support for command line parameters
- added experimental TCP stream compression (imptcp only, currently)
- added BSD-specific syslog facilities
* "console"
* "bsd_security" - this is called "security" under BSD, but that name
was unfortunately already taken by some standard facility. So I
did the (hopefully) second-best thing and renamed it a little.
- imported fixes from 7.4.2 (especially build problems on FreeBSD)
- bugfix: imptcp did not properly initialize compression status variable
could lead to segfault if stream:always compression mode was selected
---------------------------------------------------------------------------
Version 7.5.0 [devel] 2013-06-11
- imrelp: implement "ruleset" module parameter
- imrelp/omrelp: add TLS & compression (zip) support

connections
Thanks to Axel Rau for the patch.
---------------------------------------------------------------------------
Version 7.4.8 [v7.4-stable] 2014-01-08
- rsgtutil provides better error messages on unfinished signature blocks
- bugfix: guard against control characters in internal (error) messages
Thanks to Ahto Truu for alerting us.
- bugfix: immark did emit messages under kern.=info instead of syslog.=info
Note that his can potentially break exisiting configurations that
rely on immark sending as kern.=info. Unfortunately, we cannot leave
this unfixed as we never should emit messages under the kern facility.
---------------------------------------------------------------------------
Version 7.4.7 [v7.4-stable] 2013-12-10
- bugfix: limiting queue disk space did not work properly
* queue.maxdiskspace actually initializes queue.maxfilesize
* total size of queue files was not checked against
queue.maxdiskspace for disk assisted queues.
Thanks to Karol Jurak for the patch.
- bugfix: linux kernel-like ratelimiter did not work properly with all
inputs (for example, it did not work with imdup). The reason was that
the PRI value was used, but that needed parsing of the message, which
was done too late.
- bugfix: disk queues created files in wrong working directory
if the $WorkDirectory was changed multiple times, all queues only
used the last value set.
- bugfix: legacy directive $ActionQueueWorkerThreads was not honored
- bugfix: segfault on startup when certain script constructs are used
e.g. "if not $msg ..."
- bugfix: imuxsock: UseSysTimeStamp config parameter did not work correctly
Thanks to Tomas Heinrich for alerting us and provinding a solution
suggestion.
- bugfix: $SystemLogUseSysTimeStamp/$SystemLogUsePIDFromSystem did not work

- improved checking of queue config parameters on startup
- bugfix: call to ruleset with async queue did not use the queue

Version 7.4.6 [v7.4-stable] 2013-10-31
- bugfix: potential abort during HUP

- bugfix: imtcp flowControl parameter incorrectly defaulted to "off"
This could cause message loss on systems under heavy load and was
a change-of-behaviour to previous version. This is a regression
most probably introduced in 5.9.0 (but did not try hard to find the
exact point of its introduction).

- now requires libestr 0.1.8 as early versions had a nasty bug in

- omelasticsearch: add failed.httprequests stats counter
- bugfix: invalid property filter was not properly disabled in ruleset
Note that this bugfix introduces a very slight memory leak, which is
cosmetic, as it just holds data until termination that is no longer
needed. It is just the part of the config that was invalid. We will
"fix" this "issue" in the devel version first, as the fix is a bit
too intrusive to do without hard need in the stable version.
- bugfix: segfault if re_extract() function was used and no match found
- bugfix: potential misadressing on startup if property-filter was used
This could happen if the property name was longer than 127 chars, a case
that would not happen in practice.
- bugfix: omelasticsearch: correct failed.http stats counter
- bugfix: omelasticsearch: did not correctly initialize stats counters
- bugfix: omelasticsearch: failed.es counter was only maintained in bulk mode
This usually did not lead to any problems, because they are in static
memory, which is initialized to zero by the OS when the plugin is
loaded. But it may cause problems especially on systems that do not
support atomic instructions - in this case the associated mutexes also
did not get properly initialized.
- bugfix: mmanon did not detect all IP addresses in rewrite mode

This fixes a problem where the TLV16 flag was improperly encoded.
Unfortunately, existing files already have the bug and may not properly

- bugfix: 100% CPU utilization when DA queue became full
- bugfix: omlibdbi did not properly close connection on some errors
This happened to errors occuring in Begin/End Transaction entry

Version 7.4.1 [v7.4-stable] 2013-06-17
- imjournal: add ratelimiting capability
The original imjournal code did not support ratelimiting at all. We
now have our own ratelimiter. This can mitigate against journal
database corruption, when the journal re-sends old data. This is a
current bug in systemd journal, but we won't outrule this to happen
in the future again. So it is better to have a safeguard in place.
By default, we permit 20,000 messages witin 10 minutes. This may
be a bit restrictive, but given the risk potential it seems reasonable.
Users requiring larger traffic flows can always adjust the value.
- bugfix: potential loop in rate limiting
if the message that tells about rate-limiting gets rate-limited itself,
it will potentially create and endless loop
- bugfix: potential segfault in imjournal if journal DB is corrupted
- bugfix: prevent a segfault in imjournal if state file is not defined

Version 7.4.0 [v7.4-stable] 2013-06-06
This starts a new stable branch based on 7.3.15 plus the following changes:
- add --enable-cached-man-pages ./configure option
permits to build rsyslog on a system where rst2man is not installed. In
that case, cached versions of the man pages are used (they were built
during "make dist", so they should be current for the version in
question.
- doc bugfix: ReadMode wrong in imfile doc, two values were swapped
Thanks to [email protected] for mentioning this
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=450
- imjournal: no longer do periodic wakeup
- bugfix: potential hang *in debug mode* on rsyslogd termination
This ONLY affected rsyslogd if it were running with debug output
enabled.
- bugfix: $template statement with multiple spaces lead to invalid tpl name
If multiple spaces were used in front of the template name, all but one
of them became actually part of the template name. So
$template a,"..." would be name " a", and as such "a" was not
available, e.g. in
*.* /var/log/file;a
This is a legacy config problem. As it was unreported for many years,
no backport of the fix to old versions will happen.
This is a long-standing bug that was only recently reported by forum
user mc-sim.

- bugfix: potential segfault on startup when builtin module was specified
in module() statement.
Thanks to Marius Tomaschewski for reporting the bug.
- bugfix: segfault due to invalid dynafile cache handling
Accidently, the old-style cache size parameter was used when the
dynafile cache was created in a RainerScript action. If the old-style
size was lower than the one actually set, this lead to misadressing
when the size was overrun, and that could lead to all kinds of
"interesting things", often in segfaults.

Version 7.3.10 [devel] 2013-04-10
- added RainerScript re_extract() function
- omrelp: added support for RainerScript-based configuration
- omrelp: added ability to specify session timeout
- templates now permit substring extraction relative to end-of-string
- bugfix: failover/action suspend did not work correctly
This was experienced if the retry action took more than one second
to complete. For suspending, a cached timestamp was used, and if the
retry took longer, that timestamp was already in the past. As a
result, the action never was kept in suspended state, and as such
no failover happened. The suspend functionalit now does no longer use
the cached timestamp (should not have any performance implication, as
action suspend occurs very infrequently).
- bugfix: gnutls RFC5425 driver had some undersized buffers
Thanks to Tomas Heinrich for the patch.
- bugfix: nested if/prifilt conditions did not work properly
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=415
- bugfix: imuxsock aborted under some conditions
regression from ratelimiting enhancements
- bugfix: build problems on Solaris
Thanks to Martin Carpenter for the patches.
---------------------------------------------------------------------------
Version 7.3.9 [devel] 2013-03-27
- support for signing logs added
- imudp: now supports user-selectable inputname
- omlibdbi: now supports transaction interface
if recent enough lbdbi is present
- imuxsock: add ability to NOT create/delete sockets during startup and
shutdown
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=259
- imfile: errors persisting state file are now reported
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=292
- imfile: now detects file change when rsyslog was inactive
Previosly, this case could not be detected, so if a file was overwritten
or rotated away while rsyslog was stopped, some data was missing. This
is now detected and the new file being forwarded right from the
beginning.
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=228
- updated systemd files to match current systemd source
- bugfix: imudp scheduling parameters did affect main thread, not imudp
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=409
- bugfix: build problem on platforms without GLOB_NOMAGIC
- bugfix: build problems on non-Linux platforms
- bugfix: stdout/stderr were not closed on forking
but were closed when running in the forground - this was just reversed
of what it should be. This is a regression of a recent change.
---------------------------------------------------------------------------
Version 7.3.8 [devel] 2013-03-18
- imrelp: now supports listening to IPv4/v6 only instead of always both
build now requires librelp 1.0.2
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=378
- bugfix: mmanon did not build on some platforms (e.g. Ubuntu)
- bugfix: segfault in expression optimizer
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=423
- bugfix: imuxsock was missing SysSock.ParseTrusted module parameter
To use that functionality, legacy rsyslog.conf syntax had to be used.
Also, the doc was missing information on the "ParseTrusted" set of
config directives.
- bugfix: include files got included in the wrong order
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=411
This happens if an $IncludeConfig directive was done on multiple
files (e.g. the distro default of $IncludeConfig /etc/rsyslog.d/*.conf).
In that case, the order of include file processing is reversed, which
could lead to all sorts of problems.
Thanks to Nathan Stratton Treadway for his great analysis of the problem,
which made bug fixing really easy.
---------------------------------------------------------------------------
Version 7.3.7 [devel] 2013-03-12
- add support for anonymizing IPv4 addresses
- add support for writing to the Linux Journal (omjournal)
- imuxsock: add capability to ignore messages from ourselfes
This helps prevent message routing loops, and is vital to have
if omjournal is used together with traditional syslog.
- field() function now supports a string as field delimiter
- added ability to configure debug system via rsyslog.conf
- bugfix: imuxsock segfault when system log socket was used
- bugfix: mmjsonparse segfault if new-style config was used
- bugfix: script == comparison did not work properly on JSON objects
- bugfix: field() function did never return "***FIELD NOT FOUND***"
instead it returned "***ERROR in field() FUNCTION***" in that case
---------------------------------------------------------------------------
Version 7.3.6 [devel] 2013-01-28
- greatly improved speed of large-array [N]EQ RainerScript comparisons
Thanks to David Lang for a related discussion that inspired the idea
to do this with a much simpler (yet sufficient) approach than orignally
planned for.
- greatly improved speed of DNS cache for large cache sizes
- general performance improvements
- omfile: added stats counters for dynafile caches
- omfile: improved async writing, finally enabled full async write
also fixed a couple of smaller issues along that way
- impstats: added ability to write stats records to local file
and avoid going through the syslog log stream. syslog logging can now
also be turned off (see doc for details).
- bugfix: imklog issued wrong facility in error messages
...what could lead to problems in other parts of the code
- fix compile problem in imklog
- added capability to output thread-id-to-function debug info
This is a useful debug aid, but nothing of concern for regular users.
---------------------------------------------------------------------------
Version 7.3.5 [devel] 2012-12-19
- ommysql: addded batching/transaction support
- enhanced script optimizer to optimize common PRI-based comparisons
These constructs are especially used in SUSE default config files,
but also by many users (as they are more readable than the equivalent
PRI-based filter).
- omudpspoof: add support for new config system
- omudpspoof: add support for packets larger than 1472 bytes
On Ethernet, they need to be transmitted in multiple fragments. While
it is known that fragmentation can cause issues, it is the best choice
to be made in that case. Also improved debug output.
- bugfix: omudpspoof failed depending on the execution environment
The v7 engine closes fds, and closed some of libnet's fds as well, what
lead to problems (unfortunately, at least some libnet versions do not
report a proper error state but still "success"...). The order of libnet
calls has been adjusted to by in sync with what the core engine does.
- bugfix: segfault on imuxsock startup if system log socket is used
and no ratelimiting supported. Happens only during initial config
read phase, once this is over, everything works stable.
- bugfix: mmnormalize build problems
- bugfix: mmnormalize could abort rsyslog if config parameter was in error
- bugfix: no error message for invalid string template parameters
rather a malformed template was generated, and error information emitted
at runtime. However, this could be quite confusing. Note that with this
"bugfix" user experience changes: formerly, rsyslog and the affected
actions properly started up, but the actions did not produce proper
data. Now, there are startup error messages and the actions are NOT
executed (due to missing template due to template error).
- bugfix[minor]: invalid error code when mmnormalize could not access
rulebase
- bugfix(kind of): script optimizer did not work for complex boolean
expressions
- doc bugfix: corrections and improvements in mmnormalize html doc page
- bugfix: some message properties could be garbled due to race condition
This happened only on very high volume systems, if the same message was
being processed by two different actions. This was a regression caused
by the new config processor, which did no longer properly enable msg
locking in multithreaded cases. The bugfix is actually a refactoring of
the msg locking code - we no longer do unlocked operations, as the use
case for it has mostly gone away. It is potentially possible only at
very low-end systems, and there the small additional overhead of doing
the locking does not really hurt. Instead, the removal of that
capability can actually slightly improve performance in common cases,
as the code path is smaller and requires slightly less memory writes.
That probably outperforms the extra locking overhead (which in the
low-end case always happens in user space, without need for kernel
support as we can always directly aquire the lock - there is no
contention at all).
- build system cleanup (thanks to Michael Biebl for this!)
- bugfix: omelasticsearch did not properly compile on some platforms
due to missing libmath. Thanks to Michael Biebl for the fix
---------------------------------------------------------------------------
Version 7.3.4 [devel] 2012-11-23
- further (and rather drastically) improved disk queue performance
we now save one third of the IO calls
- imklog: added ParseKernelTimestamp parameter (import from 5.10.2)
Thanks to Marius Tomaschewski for the patch.
- imklog: added KeepKernelTimestamp parameter (import from 5.10.2)
Thanks to Marius Tomaschewski for the patch.
- bugfix: improper handling of backslash in string-type template()s
- bugfix: leading quote (") in string-type template() lead to thight loop
on startup
- bugfix: no error msg on invalid field option in legacy/string template
- bugfix: imklog mistakenly took kernel timestamp subseconds as nanoseconds
... actually, they are microseconds. So the fractional part of the
timestamp was not properly formatted. (import from 5.10.2)
Thanks to Marius Tomaschewski for the bug report and the patch idea.
---------------------------------------------------------------------------
Version 7.3.3 [devel] 2012-11-07
- improved disk queue performance
- bugfix: dynafile zip files could be corrupted
This could happen if a dynafile was destructed before the first write.
In practice, this could happen if few lines were written to a file and
it then became evicted from the dynafile cache. This would probably
look very random, because it depended on the timing in regard to
message volume and dynafile cache size.
---------------------------------------------------------------------------
Version 7.3.2 [devel] 2012-10-30
- mmnormalize: support for v6+ config interface added
- mmjsonparse: support for v6+ config interface added
---------------------------------------------------------------------------
Version 7.3.2 [devel] 2012-10-30
- totally reworked ratelimiting and "last message repeated n times"
all over rsyslog code. Each of the supported inputs now supports
linux-like ratelimiting (formerly only imuxsock did). Also, the
"last message repeated n times" is now processed at the input side
and no longer at the output side of rsyslog processing. This
provides the basis for new future additions as well as usually more
performance and a much simpler output part (which can be even further
refactored).
- imtcp: support for Linux-Type ratelimiting added
- imptcp: support for Linux-Type ratelimiting added
- imudp enhancements:
* support for input batching added (performance improvement)
* support for Linux-Type ratelimiting added
- permited action-like statements (stop, call, ...) in action lists
- bugfix: segfault on startup when modules using MSG_PASSING mode are used
- omelasticsearch: support for writing data errors to local file added
- omelasticsearch: fix check for bulk processing status response
---------------------------------------------------------------------------
Version 7.3.1 [devel] 2012-10-19
- optimized template processing performance, especially for $NOW family
of properties
- change lumberjack cookie to "@cee:" from "@cee: "
CEE originally specified the cookie with SP, whereas other lumberjack
tools used it without space. In order to keep interop with lumberjack,
we now use the cookie without space as well. I hope this can be changed
in CEE as well when it is released at a later time.
Thanks to Miloslav Trmač for pointing this out and a similiar v7 patch.
- bugfix: imuxsock and imklog truncated head of received message
This happened only under some circumstances. Thanks to Marius
Tomaschewski, Florian Piekert and Milan Bartos for their help in
solving this issue.
- bugfix: imuxsock did not properly honor $LocalHostIPIF
---------------------------------------------------------------------------
Version 7.3.0 [devel] 2012-10-09
- omlibdbi improvements, added
* support for config load phases & module() parameters
* support for default templates
* driverdirectory is now cleanly a global parameter, but can no longer
be specified as an action paramter. Note that in previous versions
this parameter was ignored in all but the first action definition
- improved omfile zip writer to increase compression
This was achieved by somewhat reducing the robustness of the zip archive.
This is controlled by the new action parameter "VeryReliableZip".
----------------------------------------------------------------------------
Version 7.2.8 [v7-stable] 2013-0?-??
- bugfix: potential segfault on startup when builtin module was specified
in module() statement.
Thanks to Marius Tomaschewski for reporting the bug.
- bugfix: segfault due to invalid dynafile cache handling
Accidently, the old-style cache size parameter was used when the
dynafile cache was created in a RainerScript action. If the old-style
size was lower than the one actually set, this lead to misadressing
when the size was overrun, and that could lead to all kinds of
"interesting things", often in segfaults.

----------------------------------------------------------------------------
Version 7.2.7 [v7-stable] 2013-04-17
- rsyslogd startup information is now properly conveyed back to init
when privileges are beging dropped
Actually, we have moved termination of the parent in front of the
priv drop. So it shall work now in all cases. See code comments in
commit for more details.
- If forking, the parent now waits for a maximum of 60 seconds for
termination by the child
- improved debugging support in forked (auto-backgrounding) mode
The rsyslog debug log file is now continued to be written across the
fork.
- updated systemd files to match current systemd source
- bugfix: failover/action suspend did not work correctly
This was experienced if the retry action took more than one second
to complete. For suspending, a cached timestamp was used, and if the
retry took longer, that timestamp was already in the past. As a
result, the action never was kept in suspended state, and as such
no failover happened. The suspend functionalit now does no longer use
the cached timestamp (should not have any performance implication, as
action suspend occurs very infrequently).

- bugfix: script == comparison did not work properly on JSON objects
[backport from 7.3 branch]
- bugfix: imudp scheduling parameters did affect main thread, not imudp
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=409
- bugfix: imuxsock rate-limiting could not be configured via legacy conf
Rate-limiting for the system socket could not be configured via legacy
configuration directives. However, the new-style RainerScript config
options worked.
Thanks to Milan Bartos for the patch.

- bugfix: using group resolution could lead to endless loop
Thanks to Tomas Heinrich for the patch.
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=310
- bugfix: $mmnormalizeuseramsg paramter was specified with wrong type
Thank to Renzhong Zhang for alerting us of the problem.
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=420
- bugfix: RainerScript getenv() function caused segfault when var was
not found.
Thanks to Philippe Muller for the patch.
- bugfix: several issues in imkmsg
see bug tracker: http://bugzilla.adiscon.com/show_bug.cgi?id=421#c8
- bugfix: imuxsock was missing SysSock.ParseTrusted module parameter
To use that functionality, legacy rsyslog.conf syntax had to be used.
Also, the doc was missing information on the "ParseTrusted" set of
config directives.
- bugfix: parameter action.execOnlyWhenPreviousIsSuspended was accidently
of integer-type. For obvious reasons, it needs to be boolean. Note
that this change can break existing configurations if they circumvented
