Hi all, Snort <https://snort.org/> is a popular open-source network intrusion detection/prevention system (NIDS/NIPS) which allows users to define sets of rules for network traffic analysis and threat detection. These rules (and Snort's design) make use of a number of pattern matching approaches, including bulk literal scanning and regular expression matching. The Hyperscan team is pleased to release a patch that adds support for using the Hyperscan library to accelerate some of these pattern matching tasks in Snort. The patch adds a Hyperscan integration in three places: 1. A new multi-pattern literal matcher (MPSE module) called "hyperscan". 2. A faster single-pattern content string matcher, replacing the Boyer-Moore approach used by default. 3. A prefilter for PCRE, where Hyperscan is used as a prefilter check for regex options before PCRE is run. Expressions that are expensive to evaluate in PCRE may be avoided entirely depending on the result of the prefilter. You can find the patch here, including a README with instructions for its use: https://01.org/hyperscan/downloads/hyperscan-integration-snort-2.9.8.2 The patch is targeted at Snort 2.9.8.2 (the current version as of this post) and we recommend using Hyperscan 4.2.0, the current release. If you have questions, bug reports or other feedback, please don't hesitate to contact us via this list or directly. Regards, Justin
