pintos-page-allocator

You can audit Pintos kernel code by scanning source files for correct usage of palloc_get_page and verifying that malloc calls are replaced with preferred zeroed page allocation functions.

Using palloc_get_page(PAL_ZERO) in Pintos enforces memory safety by ensuring allocated pages are zeroed, preventing leakage of stale kernel data and maintaining consistent memory allocation policies.

To check error handling in Pintos memory allocation, audit the source code paths to verify that allocation failures trigger proper cleanup logic and return safe error codes.

Yes, you can audit modifications in userprog/process.c by searching the source directory for malloc and palloc_get_page usage, then compiling the module to check allocation policy compliance.

Automated memory safety checks in Pintos are limited to static source code analysis, meaning they verify correct function usage and failure handling logic but cannot guarantee runtime allocation behavior.
