Summary of Changes

Hello @nalves599, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on enhancing the reliability and robustness of the memory dumping functionality within the Linux analyzer. It refines how memory regions are identified and processed by improving the parsing of /proc/maps entries and gracefully handling unknown memory protection flags. Additionally, it provides more detailed diagnostic information in error logs to facilitate quicker debugging of memory acquisition issues.

Highlights

• Improved /proc/maps Parsing: The regular expression used to parse /proc/<pid>/maps in the Linux analyzer has been updated to be more accurate and robust, aligning with the man 5 proc_pid_maps format and correctly extracting full permission strings and pathnames.
• Enhanced Error Logging: Error messages for memory dumping failures now include more contextual information, such as the specific memory range, permissions, and pathname, which will aid in debugging.
• Safer Memory Protection String Conversion: The _prot_to_str method now uses a safer dictionary lookup with a default 'UNKNOWN' value, preventing potential crashes when encountering unmapped or unrecognized memory protection flags.

Code Review

This pull request aims to fix memory dumping by updating the regex for parsing /proc/<pid>/maps and improving error logging. It also includes a fix for a potential KeyError in lib/cuckoo/common/objects.py.

I've found a critical issue in analyzer/linux/analyzer.py where the application could crash if a line from the maps file doesn't match the regular expression. I've provided a suggestion to fix this. The other changes look good.
