Changelog for 7.4.1 (v7-stable)
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
- bugfix imzmq3: potential segfault on startup
if no problem happend at startup, everything went fine
Thanks to Hongfei Cheng and Brian Knox for the patch
Changelog for 7.5.0 (v7-devel)
Version 7.5.0 [devel] 2013-06-11
- imrelp: implement “ruleset” module parameter
- imrelp/omrelp: add TLS & compression (zip) support
- omrelp: add “rebindInterval” parameter
- add -S command line option to specify IP address to use for RELP client connections
Thanks to Axel Rau for the patch.
Changelog for 7.4.0 (v7-stable)
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 jokajak@gmail.com 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.

Changelog for 7.3.14 (v7-beta)
Version 7.3.14 [beta] 2013-05-06
- bugfix: some man pages were not properly installed either rscryutil or rsgtutil man was installed, but not both Thanks to Marius Tomaschewski for the patch.
- 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. closes: http://bugzilla.adiscon.com/

A remporary buffer was allocated one byte too small. Did only affect startup, not actual operations. Came up during routine tests, and can have no effect once the engine runs. Bug was introduced in 7.3.11. - bugfix: build problems on Solaris
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=436 - bugfix: block size limit was not properly honored
- bugfix: potential segfault in guardtime signature provider

Changelog for 7.2.7 (v7-stable)
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: nested if/prifilt conditions did not work properly
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=415 - 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.
closes: http://bugzilla.adiscon.com/show_bug.cgi?id=390 - 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
the problem by using 0/1 values. - doc bugfix: rsyslog.conf man page had invalid file format info
Changelog for 7.3.10 (v7-devel)
Version 7.3.10 [devel] 2013-04-10

- omrelp: added support for RainerScript-based configuration

- 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

is now detected and the new file being forwarded right from the
beginning.

- 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.
