- `normal`: matches 401 with supplied username only
- `ddos`: matches 401 without supplied username only
- `aggressive`: matches 401 and any variant (with and without username)
closes gh-2693
no mails-action added per default anymore (e. g. to allow that `action = %(action_mw)s` should be specified per jail or in default section in jail.local), closes gh-2357;
ensure we've unique action name per jail (also if parameter `actname` is not set but name deviates from standard name, gh-2686);
don't use %(banaction)s interpolation because it can be complex value (containing `[...]`), so would bother the action interpolation.
amend to 62b1712d22 (PR #2387, backend-related option `logtype`);
testSampleRegexsZZZ-GENERIC-EXAMPLE covering now negative case also (other daemon in prefix line)
- avoid duplicates in "matches" (previously always added matches of pending failures to every next real failure, or nofail-helper recognized IP, now first failure only);
- several optimizations of merge mechanism (multi-line parsing);
fail2ban-regex: better output handling, extended with tag substitution (ex.: `-o 'fail <ip>, user <F-USER>: <msg>'`); consider a string containing new-line as multi-line log-excerpt (not as a single log-line)
filter.d/sshd.conf: introduced parameter `publickey` (allowing change behavior of "Failed publickey" failures):
- `nofail` (default) - consider failed publickey (legitimate users) as no failure (helper to get IP and user-name only)
- `invalid` - consider failed publickey for invalid users only;
- `any` - consider failed publickey for valid users too;
- `ignore` - ignore "Failed publickey ..." failures (don't consider failed publickey at all)
tests/samplestestcase.py: SampleRegexsFactory gets new failJSON option `constraint` to allow ignore of some tests depending on filter name, options and test parameters
avoid overwrite of data with empty tags by ticket constructed from multi-line failures;
amend to d1b7e2b5fb2b389d04845369d7d29db65425dcf2: better output (as well as ignoring of pending lines) using `--out msg`;
filter.d/sshd.conf: don't forget mlf-cache on "disconnecting: too many authentication failures" - message does not have IP (must be followed by "closed [preauth]" to obtain host-IP).
this is avoided if some sets were added manually or can be avoided via overwriting of parameter `_nft_shutdown_table`, for example:
banaction = nftables[_nft_shutdown_table=''][...]
- ignore errors from mod_evasive in `normal` mode (mode-controlled now) (gh-2548);
- extended with option `mode` - `normal` (default) and `aggressive`
close gh-2548
`banaction = nftables[type=multiport]` with `protocol="tcp,udp,sctp"` in jail replace 3 separate actions.
more robust if deleting multiple references to set (rules in chain)
- nftables-common is removed
- nftables-allports is obsolete, replaced by nftables[type=allports]
- nftables-multiport is obsolete, replaced by nftables[type=multiport]
Log format changed since ver. 9.11.0
Ref. ftp://ftp.isc.org/isc/bind9/9.11.0/RELEASE-NOTES-bind-9.11.0.html
"The logging format used for querylog has been altered. It now includes an additional field indicating the address in memory of the client object processing the query."
