sebres 42714d0849 filter.d/common.conf: closes gh-2650, avoid substitute of default values in related `lt_*` section, `__prefix_line` should be interpolated in definition section (after the config considers all sections that can overwrite it);

sebres f088e7bf76 Merge branch '0.10' into 0.11 2020-03-02 17:10:48 +01:00
sebres 6281dc3633 failmanager, ticket: avoid reset of retry count by pause between attempts near to findTime - adjust time of ticket will now change current attempts considering findTime as an estimation from rate by previous known interval (if it exceeds the findTime);
this should avoid some false positives as well as provide more safe handling around `maxretry/findtime` relation especially on busy circumstances.

sebres 4766547e1f performance optimization of `datepattern` (better search algorithm);
datetemplate: improved anchor detection for capturing groups `(^...)`; introduced new prefix `{UNB}` for `datepattern` to disable word boundaries in regex;
datedetector: speedup special case if only one template is defined (every match wins - no collision, no sorting, no other best match possible)

Christopher Gurnee df885586d4 close Popen() pipes explicitly for PyPy
Waiting for garbage collection to close pipes opened by Popen() can
lead to "Too many open files" errors with PyPy; close them explicitly.

sebres 14e68eed72 performance: set fetch handler getGroups depending on presence of alternate tags in RE (simplest variant or merged with alt-tags) in regex constructor 2020-02-13 12:31:15 +01:00
sebres 9137c7bb23 filter processing:
- 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
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 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).

implements new command line option `--pname` to specify it by start of server (default `fail2ban-server`);
closes gh-2623 (revert change of main thread-name, because it can affect process-name too, so `pgrep` & co. may be confused)

Fixing --withouth-test install option
2020-01-16 13:45:49 +01:00
Angelo Compagnucci 5fa1f69264 setup.py: adding option to install without tests
Tests files are not always needed especially when installing on low
resource systems like an embedded one.
This patch adds the --without-tests option to skip installing the
tests files.

Angelo Compagnucci 3965d690b1 Revert "setup.py: adding option to install without tests"
Test should actually removed from the stup data in finalize_options
instead of being added back.

This reverts commit 9b918bba2f.
