sebres 2ba9fee79f Merge branch 'master' into debian 2024-04-25 23:54:22 +02:00

sebres 1ec9237e53 bypass additional pid in prefix (may be logged by syslog-ng, gh-3060); matches protocol error with authentication mechanism not supported 2024-03-25 15:52:06 +01:00
sebres c80908837f `filter.d/exim.conf`: 
- messages are prefiltered by `prefregex` now
  - filter can bypass additional timestamp that may be logged via systemd-journal (gh-3060)

Vladimir Varlamov 8da0a99cde pid part may contain full hostname 2024-03-22 22:38:33 +03:00
Vladimir Varlamov 806a27cb4f final `<HOST>` to `<ADDR>` conversion 2024-03-22 22:38:33 +03:00
sebres e605415f61 simplify fields-group a bit (everything up to 4 chars long but H), so it'll be faster (no multiple branches) as well as would theoretically accept future enhancements of logged fields. 2024-03-22 16:47:54 +01:00
sebres c22a83933b let's use `<ADDR>` instead `<HOST>` - only IPs expected, since host-name bypassed before it (directly after H=) 2024-03-22 16:35:46 +01:00
Vladimir Varlamov df94ec4c52 filter.d/exim.conf: rewrite host line regex for all varied exim's log_selector states 
Depending on Exim's log_selector settings, log lines may contain additional information about the connection. And also the line itself with the address of the remote host can vary greatly. But fortunately, all states can be found in the Exim code itself and taken into account. Makes it easier to add new regexps.
Closes #3263
