Merge pull request #1669 from sebres/0.10-recognize-restored-tickets

Recognize state of restored tickets

ChangeLog

@@ -165,6 +165,31 @@ fail2ban-client set loglevel INFO
   - faster match and fewer searching of appropriate templates
     (DateDetector.matchTime calls rarer DateTemplate.matchDate now);
   - several standard filters extended with exact prefixed or anchored date templates;
+* Added possibility to recognize restored state of the tickets (see gh-1669).
+  New option `norestored` introduced, to ignore restored tickets (after restart).
+  To avoid execution of ban/unban for the restored tickets, `norestored = true`
+  could be added in definition section of action.
+  For conditional usage in the shell-based actions an interpolation `<restored>` 
+  could be used also. E. g. it is enough to add following script-piece at begin
+  of `actionban` (or `actionunban`) to prevent execution:
+  `if [ '<restored>' = '1' ]; then exit 0; fi;`
+  Several actions extended now using `norestored` option:
+  - complain.conf
+  - dshield.conf
+  - mail-buffered.conf
+  - mail-whois-lines.conf
+  - mail-whois.conf
+  - mail.conf
+  - sendmail-buffered.conf
+  - sendmail-geoip-lines.conf
+  - sendmail-whois-ipjailmatches.conf
+  - sendmail-whois-ipmatches.conf
+  - sendmail-whois-lines.conf
+  - sendmail-whois-matches.conf
+  - sendmail-whois.conf
+  - sendmail.conf
+  - smtp.py
+  - xarf-login-attack.conf
 * fail2ban-testcases:
   - `assertLogged` extended with parameter wait (to wait up to specified timeout,
     before we throw assert exception) + test cases rewritten using that
