This resulted in a fixed upper limit of 200 connections. +- bugfix: the default for $DirCreateMode was 0644, and as such wrong. + It has now been changed to 0700. For some background, please see + http://lists.adiscon.net/pipermail/rsyslog/2009-April/001986.html +--------------------------------------------------------------------------- +Version 3.20.5 [v3-stable] (rgerhards), 2009-04-02 +- bugfix: potential abort with DA queue after high watermark is reached + There exists a race condition that can lead to a segfault. Thanks + go to vbernetr, who performed the analysis and provided patch, which + I only tweaked a very little bit. +- fixed bugs in RainerScript: + o when converting a number and a string to a common type, both were + actually converted to the other variable's type. + o the value of rsCStrConvertToNumber() was miscalculated. + Thanks to varmojfekoj for the patch +- fixed a bug in configure.ac which resulted in problems with + environment detection - thanks to Michael Biebl for the patch +- fixed a potential segfault problem in gssapi code + thanks to varmojfekoj for the patch +- doc enhance: provide standard template for MySQL module and instructions + on how to modify schema +--------------------------------------------------------------------------- +Version 3.20.4 [v3-stable] (rgerhards), 2009-02-09 +- bugfix: inconsistent use of mutex/atomic operations could cause segfault + details are too many, for full analysis see blog post at: + http://blog.gerhards.net/2009/01/rsyslog-data-race-analysis.html +- bugfix: invalid ./configure settings for RFC3195 + thanks to Michael Biebl for the patch +- bugfix: invalid mutex access in msg.c +- doc bugfix: dist tarball missed 2 files, had one extra file that no + longer belongs into it. Thanks to Michael Biebl for pointing this out. +--------------------------------------------------------------------------- +Version 3.20.3 [v3-stable] (rgerhards), 2009-01-19 +- doc bugfix: v3-compatiblity document had typo in config directive + thanks to Andrej for reporting this +- fixed a potential segfault condition with $AllowedSender directive + On HUP, the root pointers were not properly cleaned up. Thanks to + Michael Biebel, olgoat, and Juha Koho for reporting and analyzing + the bug. +--------------------------------------------------------------------------- +Version 3.20.2 [v3-stable] (rgerhards), 2008-12-04 +- re-release of 3.20.1 with an additional fix, that could also lead + to DoS; 3.20.1 has been removed from the official download archives +- security fix: imudp emitted a message when a non-permitted sender + tried to send a message to it. This behaviour is operator-configurable. + If enabled, a message was emitted each time. That way an attacker could + effectively fill the disk via this facility. The message is now + emitted only once in a minute (this currently is a hard-coded limit, + if someone comes up with a good reason to make it configurable, we + will probably do that). +--------------------------------------------------------------------------- +Version 3.20.1 [v3-stable] (rgerhards), 2008-12-04 +- security bugfix: $AllowedSender was not honored, all senders were + permitted instead +- enhance: regex nomatch option "ZERO" has been added + This allows to return the string 0 if a regular expression is + not found. This is probably useful for storing numerical values into + database columns. +- bugfix: memory leak in gtls netstream driver fixed + memory was lost each time a TLS session was torn down. This could + result in a considerable memory leak if it happened quite frequently + (potential system crash condition) +- doc update: documented how to specify multiple property replacer + options + link to new online regex generator tool added +- minor bufgfix: very small memory leak in gtls netstream driver + around a handful of bytes (< 20) for each HUP +- improved debug output for regular expressions inside property replacer + RE's seem to be a big trouble spot and I would like to have more + information inside the debug log. So I decided to add some additional + debug strings permanently. +--------------------------------------------------------------------------- +Version 3.20.0 [v3-stable] (rgerhards), 2008-11-05 +- this is the inital release of the 3.19.x branch as a stable release +- bugfix: double-free in pctp netstream driver. Thank to varmojfeko + for the patch +--------------------------------------------------------------------------- +Version 3.19.12 [BETA] (rgerhards), 2008-10-16 +- bugfix: subseconds where not correctly extracted from a timestamp + if that timestamp did not contain any subsecond information (the + resulting string was garbagge but should have been "0", what it + now is). +- increased maximum size of a configuration statement to 4K (was 1K) +- imported all fixes from the stable branch (quite a lot) +- bugfix: (potentially big) memory leak on HUP if queues could not be + drained before timeout - thanks to David Lang for pointing this out +--------------------------------------------------------------------------- +Version 3.19.11 [BETA] (rgerhards), 2008-08-25 +This is a refresh of the beta. No beta-specific fixes have been added. +- included fixes from v3-stable (most importantly 3.18.3) +--------------------------------------------------------------------------- +Version 3.19.10 [BETA] (rgerhards), 2008-07-15 +- start of a new beta branch based on former 3.19 devel branch +- bugfix: bad memory leak in disk-based queue modes +- bugfix: UDP syslog forwarding did not work on all platforms + the ai_socktype was incorrectly set to 1. On some platforms, this + lead to failing name resolution (e.g. FreeBSD 7). Thanks to HKS for + reporting the bug. +- bugfix: priority was incorrectly calculated on FreeBSD 7, + because the LOG_MAKEPRI() C macro has a different meaning there (it + is just a simple addition of faciltity and severity). I have changed + this to use own, consistent, code for PRI calculation. Thank to HKS + for reporting this bug. +- bugfix (cosmetical): authorization was not checked when gtls handshake + completed immediately. While this sounds scary, the situation can not + happen in practice. We use non-blocking IO only for server-based gtls + session setup. As TLS requires the exchange of multiple frames before + the handshake completes, it simply is impossible to do this in one + step. However, it is useful to have the code path correct even for + this case - otherwise, we may run into problems if the code is changed + some time later (e.g. to use blocking sockets). Thanks to varmojfekoj + for providing the patch. +- important queue bugfix from 3.18.1 imported (see below) +- cleanup of some debug messages +--------------------------------------------------------------------------- +Version 3.19.9 (rgerhards), 2008-07-07 +- added tutorial for creating a TLS-secured syslog infrastructure +- rewritten omusrmsg to no longer fork() a new process for sending messages + this caused some problems with the threading model, e.g. zombies. Also, + it was far less optimal than it is now. +- bugfix: machine certificate was required for client even in TLS anon mode + Reference: http://bugzilla.adiscon.com/show_bug.cgi?id=85 + The fix also slightly improves performance by not storing certificates in + client sessions when there is no need to do so. +- bugfix: RainerScript syntax error was not always detected +--------------------------------------------------------------------------- +Version 3.19.8 (rgerhards), 2008-07-01 +- bugfix: gtls module did not correctly handle EGAIN (and similar) recv() + states. This has been fixed by introducing a new abstraction layer inside + gtls. +- added (internal) error codes to error messages; added redirector to + web description of error codes + closes bug http://bugzilla.adiscon.com/show_bug.cgi?id=20 +- disabled compile warnings caused by third-party libraries +- reduced number of compile warnings in gcc's -pedantic mode +- some minor documentation improvements +- included all fixes from beta 3.17.5 +--------------------------------------------------------------------------- +Version 3.19.7 (rgerhards), 2008-06-11 +- added new property replacer option "date-subseconds" that enables + to query just the subsecond part of a high-precision timestamp +- somewhat improved plain tcp syslog reliability by doing a connection + check before sending. Credits to Martin Schuette for providing the + idea. Details are available at + http://blog.gerhards.net/2008/06/reliable-plain-tcp-syslog-once-again.html +- made rsyslog tickless in the (usual and default) case that repeated + message reduction is turned off. More info: + http://blog.gerhards.net/2008/06/coding-to-save-environment.html +- some build system cleanup, thanks to Michael Biebl +- bugfix: compile under (Free)BSD failed due to some invalid library + definitions - this is fixed now. Thanks to Michael Biebl for the patch. +--------------------------------------------------------------------------- +Version 3.19.6 (rgerhards), 2008-06-06 +- enhanced property replacer to support multiple regex matches +- bugfix: part of permittedPeer structure was not correctly initialized + thanks to varmojfekoj for spotting this +- bugfix: off-by-one bug during certificate check +- bugfix: removed some memory leaks in TLS code +--------------------------------------------------------------------------- +Version 3.19.5 (rgerhards), 2008-05-30 +- enabled Posix ERE expressions inside the property replacer + (previously BRE was permitted only) +- provided ability to specify that a regular expression submatch shall + be used inside the property replacer +- implemented in property replacer: if a regular expression does not match, + it can now either return "**NO MATCH** (default, as before), a blank + property or the full original property text +- enhanced property replacer to support multiple regex matches +--------------------------------------------------------------------------- +Version 3.19.4 (rgerhards), 2008-05-27 +- implemented x509/certvalid gtls auth mode +- implemented x509/name gtls auth mode (including wildcards) +- changed fingerprint gtls auth mode to new format fingerprint +- protected gtls error string function by a mutex. Without it, we + could have a race condition in extreme cases. This was very remote, + but now can no longer happen. +- changed config directive name to reflect different use + $ActionSendStreamDriverCertFingerprint is now + $ActionSendStreamDriverPermittedPeer and can be used both for + fingerprint and name authentication (similar to the input side) +- bugfix: sender information (fromhost et al) was missing in imudp + thanks to sandiso for reporting this bug +- this release fully inplements IETF's syslog-transport-tls-12 plus + the latest text changes Joe Salowey provided via email. Not included + is ipAddress subjectAltName authentication, which I think will be + dropped from the draft. I don't think there is any real need for it. +This release also includes all bug fix up to today from the beta +and stable branches. Most importantly, this means the bugfix for +100% CPU utilization by imklog. +--------------------------------------------------------------------------- +Version 3.19.3 (rgerhards), 2008-05-21 +- added ability to authenticate the server against its certificate + fingerprint +- added ability for client to provide its fingerprint +- added ability for server to obtain client cert's fingerprint +- bugfix: small mem leak in omfwd on exit (strmdriver name was not freed) +- bugfix: $ActionSendStreamDriver had no effect +- bugfix: default syslog port was no longer used if none was + configured. Thanks to varmojfekoj for the patch +- bugfix: missing linker options caused build to fail on some + systems. Thanks to Tiziano Mueller for the patch. +--------------------------------------------------------------------------- +Version 3.19.2 (rgerhards), 2008-05-16 +- bugfix: TCP input modules did incorrectly set fromhost property + (always blank) +- bugfix: imklog did not set fromhost property +- added "fromhost-ip" property + Note that adding this property changes the on-disk format for messages. + However, that should not have any bad effect on existing spool files. + But you will run into trouble if you create a spool file with this + version and then try to process it with an older one (after a downgrade). + Don't do that ;) +- added "RSYSLOG_DebugFormat" canned template +- bugfix: hostname and fromhost were swapped when a persisted message + (in queued mode) was read in +- bugfix: lmtcpclt, lmtcpsrv and lmgssutil did all link to the static + runtime library, resulting in a large size increase (and potential + "interesting" effects). Thanks to Michael Biebel for reporting the size + issue. +- bugfix: TLS server went into an endless loop in some situations. + Thanks to Michael Biebl for reporting the problem. +- fixed potential segfault due to invalid call to cfsysline + thanks to varmojfekoj for the patch +--------------------------------------------------------------------------- +Version 3.19.1 (rgerhards), 2008-05-07 +- configure help for --enable-gnutls wrong - said default is "yes" but + default actually is "no" - thanks to darix for pointing this out +- file dirty.h was missing - thanks to darix for pointing this out +- bugfix: man files were not properly distributed - thanks to + darix for reporting and to Michael Biebl for help with the fix +- some minor cleanup +--------------------------------------------------------------------------- +Version 3.19.0 (rgerhards), 2008-05-06 +- begins new devel branch version +- implemented TLS for plain tcp syslog (this is also the world's first + implementation of IETF's upcoming syslog-transport-tls draft) +- partly rewritten and improved omfwd among others, now loads TCP + code only if this is actually necessary +- split of a "runtime library" for rsyslog - this is not yet a clean + model, because some modularization is still outstanding. In theory, + this shall enable other utilities but rsyslogd to use the same + runtime +- implemented im3195, the RFC3195 input as a plugin +- changed directory structure, files are now better organized +- a lot of cleanup in regard to modularization +- -c option no longer must be the first option - thanks to varmjofekoj + for the patch +--------------------------------------------------------------------------- +Version 3.18.7 (rgerhards), 2008-12-?? - bugfix: the default for $DirCreateMode was 0644, and as such wrong. It has now been changed to 0700. For some background, please see http://lists.adiscon.net/pipermail/rsyslog/2009-April/001986.html |
