sebres 9e28b6c65f filter.d/asterisk.conf: relaxing protocol RE-part before IP in RemoteAddress (gh-2531) 2019-09-26 21:46:26 +02:00
sebres 62b1712d22 amend to #2387:
- common.conf: rewritten using section-based handling round about option logtype;
- option `logtype` extended with `rfc5424` to cover RFC 5424 log-format (see #2309);
2019-07-09 21:48:43 +02:00
sebres e268bf97d4 introduces new configuration parameter "logtype" (default "file" for file-backends, and "journal" for journal-backends);
common.conf: differentiate "__prefix_line" for file/journal logtype's (speedup and fix parsing of systemd-journal);
samplestestcase.py: extends testSampleRegexsFactory to allow coverage of journal logtype;
closes gh-2383: asterisk can log timestamp if logs into systemd-journal (regex extended with optional part matching this)

sebres a5b62a7f36 failregex extended and simplified (partially ported from gh-1409). 2017-07-18 16:34:22 +02:00
sebres 098abae4e6 Remove greedy catch-all before `<HOST>`, make regex more universal, fewer prone to errors (should avoid future changes, if some optional parameters coming again before/after `RemoteAddress`) + non-captured groups now.
Test for possible injection (5.6.7.8 in session-id) already available, line 59 (thus already covered).

sebres 22afdbd536 Several filters optimized with pre-filtering using new option `prefregex` 2017-02-21 15:54:59 +01:00
sebres ab0ac2111c added possibility to specify more precise default date pattern:
- `datepattern = {^LN-BEG}` - only line-begin anchored default patterns
     (matches date only at begin of line, or with max distance up to 2 non-alphanumeric characters from line-begin);
  - `datepattern = {*WD-BEG}` - only word-begin anchored default patterns;
  - `datepattern = ^prefix{DATE}suffix` - exact specified default patterns (using prefix and suffix);
common filter configs gets a more precise, line-begin anchored (datepattern = {^LN-BEG}) resp. custom anchoring default date-patterns;

sebres f5f204ca7c Improved changes of gh-1458:
`[^']*` after callid was wrong, changed to `[^\)]*`;
  regexp anchored at the end;
  almost the same regex grouped to one;

Closes #1458

sebres cb4f9be8b2 the date brackets removed from filters using `__prefix_line`, because `__prefix_line` already contains the date ambit; 2016-05-17 11:55:02 +02:00

Thanks to @kcormier.

Ivan Poddubny 988d9a08da Asterisk security log: accept events containing Response/ExpectedResponse
Event containing Challenge may come without ReceivedChallenge, but with
Response and ExpectedResponse.
Also Challenge now accepts '/' character, since it is used at least by PJSIP.

Ivan Poddubny 189265a323 Asterisk security log: accept SessionID of PJSIP events
Unlike chan_sip and manager, PJSIP populates SessionID using
Call-Id header of a related SIP message.
As Call-Id of a SIP message can contain almost anything,
the regular expression for SessionID has been loosened.
