2021-11-03 15:47:45 +01:00
sebres 3b02098817 several backends optimizations (in file and journal filters):
- don't need to wait if we still had log-entries from last iteration (which got interrupted for servicing)
- rewritten update log/journal position, it is more stable and faster now (fewer DB access and surely up-to-date at end)

sebres ec043cd202 simplifying logic and shortening messages (delta in minutes; removed clock synchronization, because it is rarely an issue on fail2ban side, e. g. for remote logs only, etc) 2021-09-19 21:58:42 +02:00

sebres 1e4a14fb25 pyinotify: fixes sporadic runtime error "dictionary changed size during iteration" (if something outside changes the pending dict during _checkPending evaluation) - simply deserialize to a list for iteration, without any lock, because unneeded here due to small and mostly empty dictionary (logrotate, etc), not to mention that pending check is normally called once per minute;
don't call process file inside of server thread calling of addLogPath (always retard it as pending event);
ensure to wake-up as soon as possible to process pending events (e. g. if file gets added).

sebres f381b98246 introduces new flavor short for fail2ban-client status $jail short: output total and current counts only, without banned IPs list in order to speedup it and to provide more clear output (gh-2819), flavor basic (still default) is unmodified for backwards compatibility;
it can be changed later to `short`, so for full list of IPs in newer version one should better use:
  - `fail2ban-client status $jail basic`
  - `fail2ban-client get $jail banned` or `fail2ban-client banned`

sebres 9137c7bb23 filter processing:

  - 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):

  - `any` - consider failed publickey for valid users too;

tests/samplestestcase.py: SampleRegexsFactory gets new failJSON option `constraint` to allow ignore of some tests depending on filter name, options and test parameters
2020-02-13 12:28:07 +01:00
sebres 1492ab2247 improve processing of pending failures (lines without ID/IP) - fail2ban-regex would show those in matched lines now (as well as increase count of matched RE);
avoid overwrite of data with empty tags by ticket constructed from multi-line failures;
amend to d1b7e2b5fb: 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).

Shane Forsythe 8614ca8c41 Update proftpd.conf
proftpd 1.3.5e can leave inconsistent error message if ftp or mod_sftp is used

Oct  2 15:45:31 ftp01 proftpd[5516]: 10.10.2.13 (10.10.2.189[10.10.2.189]) - SECURITY VIOLATION: Root login attempted

Fix regex to make trailing period optional, otherwise brute force attacks against root account using ftp are not blocked correctly.

Fail2Ban: Changelog
===================
Incompatibility list (compared to v.0.9):
ver. 0.10.6 (2020/11/23) - just-what-the-doctor-ordered
-----------
### Incompatibility list (v.0.10 compared to v.0.9):
* Filter (or `failregex`) internal capture-groups:
- If you've your own `failregex` or custom filters using conditional match `(?P=host)`, you should
@@ -30,6 +31,67 @@ Incompatibility list (compared to v.0.9):
* Since v0.10 fail2ban supports the matching of IPv6 addresses, but not all ban actions are
IPv6-capable now.
### Fixes
* [stability] prevent race condition - no ban if filter (backend) is continuously busy if
too many messages will be found in log, e. g. initial scan of large log-file or journal (gh-2660)
* pyinotify-backend sporadically avoided initial scanning of log-file by start
* python 3.9 compatibility (and Travis CI support)
* restoring a large number (500+ depending on files ulimit) of current bans when using PyPy fixed
* manual ban is written to database, so can be restored by restart (gh-2647)
* `jail.conf`: don't specify `action` directly in jails (use `action_` or `banaction` instead)
* 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 `[...]` and/or quotes),
so would bother the action interpolation
* fixed type conversion in config readers (take place after all interpolations get ready), that allows to
specify typed parameters variable (as substitutions) as well as to supply it in other sections or as init parameters.
* `action.d/*-ipset*.conf`: several ipset actions fixed (no timeout per default anymore), so no discrepancy
between ipset and fail2ban (removal from ipset will be managed by fail2ban only, gh-2703)
* `action.d/cloudflare.conf`: fixed `actionunban` (considering new-line chars and optionally real json-parsing
with `jq`, gh-2140, gh-2656)
* `action.d/nftables.conf` (type=multiport only): fixed port range selector, replacing `:` with `-` (gh-2763)
* `action.d/firewallcmd-*.conf` (multiport only): fixed port range selector, replacing `:` with `-` (gh-2821)
* `action.d/bsd-ipfw.conf`: fixed selection of rule-no by large list or initial `lowest_rule_num` (gh-2836)
* `filter.d/common.conf`: avoid substitute of default values in related `lt_*` section, `__prefix_line`
should be interpolated in definition section (inside the filter-config, gh-2650)
* `filter.d/dovecot.conf`:
- add managesieve and submission support (gh-2795);
- accept messages with more verbose logging (gh-2573);
* `filter.d/courier-smtp.conf`: prefregex extended to consider port in log-message (gh-2697)
* `filter.d/traefik-auth.conf`: filter extended with parameter mode (`normal`, `ddos`, `aggressive`) to handle
the match of username differently (gh-2693):
- `normal`: matches 401 with supplied username only
- `ddos`: matches 401 without supplied username only
- `aggressive`: matches 401 and any variant (with and without username)
* `filter.d/sshd.conf`: normalizing of user pattern in all RE's, allowing empty user (gh-2749)
### New Features and Enhancements
* fail2ban-regex:
- speedup formatted output (bypass unneeded stats creation)
- extended with prefregex statistic
- more informative output for `datepattern` (e. g. set from filter) - pattern : description
* parsing of action in jail-configs considers space between action-names as separator also
(previously only new-line was allowed), for example `action = a b` would specify 2 actions `a` and `b`
* new filter and jail for GitLab recognizing failed application logins (gh-2689)
* new filter and jail for Grafana recognizing failed application logins (gh-2855)
* new filter and jail for SoftEtherVPN recognizing failed application logins (gh-2723)
* `filter.d/guacamole.conf` extended with `logging` parameter to follow webapp-logging if it's configured (gh-2631)
* `filter.d/bitwarden.conf` enhanced to support syslog (gh-2778)
* introduced new prefix `{UNB}` for `datepattern` to disable word boundaries in regex;
* datetemplate: improved anchor detection for capturing groups `(^...)`;
* datepattern: improved handling with wrong recognized timestamps (timezones, no datepattern, etc)
as well as some warnings signaling user about invalid pattern or zone (gh-2814):
- filter gets mode in-operation, which gets activated if filter starts processing of new messages;
in this mode a timestamp read from log-line that appeared recently (not an old line), deviating too much
from now (up too 24h), will be considered as now (assuming a timezone issue), so could avoid unexpected
bypass of failure (previously exceeding `findtime`);
- better interaction with non-matching optional datepattern or invalid timestamps;
- implements special datepattern `{NONE}` - allow to find failures totally without date-time in log messages,
whereas filter will use now as timestamp (gh-2802)
* performance optimization of `datepattern` (better search algorithm in datedetector, especially for single template);
* fail2ban-client: extended to unban IP range(s) by subnet (CIDR/mask) or hostname (DNS), gh-2791;
