Fail2Ban: Changelog
|
||||
===================
|
||||
|
||||
ver. 1.0.2 (2022/11/09) - finally-war-game-test-tape-not-a-nuclear-alarm
|
||||
-----------
|
||||
|
||||
### Fixes
|
||||
* backend `systemd`: code review and several fixes:
|
||||
- wait only if it is necessary, e. g. in operational mode and if no more entries retrieved (end of journal);
|
||||
- ensure we give enough time after possible rotation, vacuuming or adding/removing journal files,
|
||||
and move cursor back and forth to avoid entering dead space
|
||||
* `filter.d/named-refused.conf`:
|
||||
- support BIND named log categories, gh-3388
|
||||
- allow `info:` as possible error prefix too ("query (cache) denied" may occur as info)
|
||||
* `filter.d/dovecot.conf`:
|
||||
- fixes regression introduced in gh-3210: resolve extremely long search by repeated apply of non-greedy RE-part
|
||||
with following branches (it may be extremely slow up to infinite search depending on message), gh-3370
|
||||
- fixes regression and matches new format in aggressive mode too (amend to gh-3210)
|
||||
|
||||
### New Features and Enhancements
|
||||
|
||||
|
||||
ver. 1.0.1 (2022/09/27) - energy-equals-mass-times-the-speed-of-light-squared
|
||||
