This project belongs to the practical course Advanced Systems Programming in C/Rust

1. task1_syscalls: use syscall API and asm assembly to implement read/write; use ptrace mechanism to trace a subprocess's read/write syscall and its return value
2. task2_fileio: use FUSE API to implement a in-memory filesystem
3. task3_process: implement an interactive shell(including pipeline and builtin commands)
4. task4_concurrency: implement spinlock(based on CAS), lock-based hashmap and lock-free hashmap
5. task5_memory: implement an efficient heap memory management(malloc, free, calloc, realloc) by reusing/spliting/merging free blocks; implement a thread-safe malloc by TLS
6. task6_sockets: implement a TCP/IP server(with multithreaded epoll) and client
7. task7_performance: gdb, perf, bcc, flamegraph, etc.
8. task8_container: build a sandbox based on the Linux namespace mechanism
