[syslog-ng] syslog-ng-3.28.1

[Laszlo Budai]

3.28.1
Highlights

  *   http: add support for proxy option

Example:

log {
   source { system(); };
   destination { http( url("SYSLOG_SERVER_IP:PORT") proxy("PROXY_IP:PORT") method("POST") ); };
};


(#3253<https://github.com/syslog-ng/syslog-ng/pull/3253>)

Features

  *   map: template function

This template function applies a function to all elements of a list. For example: $(map $(+ 1 $_) 0,1,2) => 1,2,3.
(#3301<https://github.com/syslog-ng/syslog-ng/pull/3301>)

  *   use-syslogng-pid(): new option to all sources

If set to yes, syslog-ng overwrites the message's ${PID} macro to its own PID.
(#3323<https://github.com/syslog-ng/syslog-ng/pull/3323>)

Bugfixes

  *   affile: eliminate infinite loop in case of a spurious file path

If the template evaluation of a log message will result to a spurious
path in the file destination, syslog-ng refuses to create that file.
However the problematic log message was left in the msg queue, so
syslog-ng was trying to create that file again in time-reopen periods.
>From now on syslog-ng will handle "permanent" file errors, and drop
the relevant msg.
(#3230<https://github.com/syslog-ng/syslog-ng/pull/3230>)

  *   Fix minor memory leaks in error scenarios
(#3265<https://github.com/syslog-ng/syslog-ng/pull/3265>)

  *   crypto: fix hang on boot due to lack of entropy
(#3271<https://github.com/syslog-ng/syslog-ng/pull/3271>)

  *   Fix IPv4 UDP destinations on FreeBSD

UDP-based destinations crashed when receiving the first message on FreeBSD due
to a bug in destination IP extraction logic.
(#3278<https://github.com/syslog-ng/syslog-ng/pull/3278>)

  *   network sources: fix TLS connection closure

RFC 5425 specifies that once the transport receiver gets close_notify from the
transport sender, it MUST reply with a close_notify.

The close_notify alert is now sent back correctly in case of TLS network sources.
(#2811<https://github.com/syslog-ng/syslog-ng/pull/2811>)

  *   disk-buffer: fixes possible crash, or fetching wrong value for logmsg nvpair
(#3281<https://github.com/syslog-ng/syslog-ng/pull/3281>)

  *   packaging/debian: fix mod-rdkafka Debian packaging
(#3282<https://github.com/syslog-ng/syslog-ng/pull/3282>)

  *   kafka destination: destination halts if consumer is down, and kafka's queue is filled
(#3305<https://github.com/syslog-ng/syslog-ng/pull/3305>)

  *   file-source: Throw error, when follow-freq() is set with a negative float number.
(#3306<https://github.com/syslog-ng/syslog-ng/pull/3306>)

  *   stats-freq: with high stats-freq syslog-ng emits stats immediately causing high memory and CPU usage
(#3320<https://github.com/syslog-ng/syslog-ng/pull/3320>)

  *   secure-logging: bug fixes (#3284<https://github.com/syslog-ng/syslog-ng/pull/3284>)

     *   template arguments are now consistently checked
     *   fixed errors when mac file not provided
     *   fixed abort when derived key not provided
     *   fixed crash with slogkey missing parameters
     *   fixed secure-logging on 32-bit architectures
     *   fixed CMake build
