Yara is a rule based scanning engine aimed to help malware analysts in finding and classifying interesting samples. https://github.com/VirusTotal/yara This series adds Yara support to Libguestfs allowing to upload sets of rules and scanning files against them. Currently provided APIs: - yara_load: loads a set of rules - yara_destroy: free resources allocated by loaded rules - yara_scan:

v6: - use new test functions - fix yara_detection struct field names - revert yara_load function to initial version With Pino we were exploring the idea of allowing Users to load multiple rule files with subsequent calls to yara_load API. https://www.redhat.com/archives/libguestfs/2016-November/msg00119.html It turns out impractical due to YARA API limitations. It is possible to load multiple
