OS_Assignment

Assignment 1

Folders

• module: a simple kernel module.
• syscall: hook sys_call_table, in order to append a new syscall without compiling kernel.

Note

• kallsyms_lookup_name was no longer export after version 5.7. Therefore we cannot find any kernel function easily.
• To tackle it, we can use kprobe, another exported method to find unexported kernel function.

Assignment 2

• Implement thread based Fibonacci number calculation program, using Java and C.
• Encapsulate <pthread.h> into thread.h. Available APIs:
  • int create(void *func);
  • void wait(int id);

Assignment 3

• Implement dynamic extended thread pool.
• Customize macro BLOCK_SIZE to fit your own needs. Default: 64.
• Available APIs:
  • int create(void *func);
  • void wait(int id);
• A possible solution to Dining Philosophers problem.
