sebres 2b358bc1a4 filter.d/apache-overflows.conf: rewritten without end-anchor ($), because apache-log could contain very long URLs (and/or referrer), the parsing of it anchored way may be very vulnerable (at least as regards the system resources, see gh-1790). 2017-06-15 11:16:19 +02:00

dovecot: Match also when user field is empty
Commit 5678d08 of 2016-11-26 changed:

    ( user=<\S*>,)?

to:

    ( user=<[^>]+>,)?

The change from `*` (zero or more times) to `+` (one or more times) may
not have been intended. It will miss lines containing, for example:

    Aborted login (tried to use disallowed plaintext auth): user=<>

This commit reverts the `+` back to `*`.

changelog updated;
2017-03-08 16:51:08 +01:00
sebres d2a3d093c6 rewritten CallingMap: performance optimized, immutable, self-referencing, template possibility (used in new ActionInfo objects);
new ActionInfo handling: saves content between actions, without interim copying (save original on demand, recoverable via reset);
test cases extended
2017-02-24 11:54:24 +01:00
sebres 35efca5941 Better multi-line handling introduced: single-line parsing with caching of needed failure information to process in further lines.
Many times faster and fewer CPU-hungry because of parsing with `maxlines=1`, so without line buffering (scrolling of the buffer-window).
Combination of tags `<F-MLFID>` and `<F-NOFAIL>` can be used now to process multi-line logs using single-line expressions:
- tag `<F-MLFID>`: used to identify resp. store failure info for groups of log-lines with the same identifier (e. g. combined failure-info for the same conn-id by `<F-MLFID>(?:conn-id)</F-MLFID>`, see sshd.conf for example)
- tag `<F-NOFAIL>`: used as mark for no-failure (helper to accumulate common failure-info);
filter.d/sshd.conf: [sshd], [sshd-ddos], [sshd-aggressive] optimized with pre-filtering using new option `prefregex` and new multi-line handling.
