v7: - Fixes according to comments - Rebase on top of 1.37.12 Matteo Cafasso (7): daemon: expose file upload logic appliance: add yara dependency New API: yara_load New API: yara_destroy New API: internal_yara_scan New API: yara_scan yara_scan: added API tests appliance/packagelist.in | 4 + configure.ac | 1 + daemon/Makefile.am

Currently, I load the RData file then ls() and str(). But loading the file takes too long if the file is big. Most of the time, I only interested what the variables are in the the file and the attributes of the variables (like if it is a data.frame, matrix, what are the colnames/rownames, etc.) I'm wondering if there is any facility in R to help me avoid loading the whole file.

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

v7: - iterate over output file instead of reading it into memory Instead of reading the whole output file in memory and iterating over the resulting buffer, use XDR primitives to directly iterate over the file itself. This should reduce the API memory consumption. Patch ready for review. Code available at: https://github.com/noxdafox/libguestfs/tree/filesystem_walk Matteo Cafasso

v9: - add missing files: java/Makefile.inc, java/com/redhat/et/libguestfs/.gitignore, gobject/Makefile.inc - reserve space in tsk_dirent struct for future usage - use int instead of bool_t type - improve API documentation Matteo Cafasso (3): New API: internal_filesystem_walk New API: filesystem_walk lib: Added filesystem_walk command tests daemon/Makefile.am

v3: - allow to load multiple rule files - added optional namespace parameter to yara_load - move destructor logic in yara module - use generic file upload logic - use generic temporary path function Matteo Cafasso (6): appliance: add yara dependency New API: yara_load New API: yara_destroy New API: internal_yara_scan New API: yara_scan yara_scan: added API tests

v8: - rebase on master - bump version to 1.33.37 - squash commits 1, 2, 3 Kept original commits messages when squashing them.

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:
