Porting ASan to NetBSD

This repository will hold the code needed to get Address Sanitizer (ASan) working to find memory bugs in the NetBSD userland and kernel.

Progress

Week 1

• Removed weak symbols from assembly stubs for intercepted syscalls.
• Begin adding interceptor functions for syscalls that write to memory.

Week 2

• Continue adding interceptor functions for syscalls writing to memory and begin adding syscalls that read from memory.
• Add touch_mem() function to touch each byte of a null-terminated string.

Week 3

• Tie up loose ends with interceptor functions.
• Begin copying the address sanitizer functionality needed for the interceptor functions.

Week 4

• Travel home to Canada.

Week 5

• Start adding support to get ASan compiling on NetBSD.
• Define private copies of non-intercepted syscalls for ASan to use.

Week 6

• Continue adding support to get ASan functioning on NetBSD.
