All,

Here is an article on gcc and clang compiler flags to use for stack protection:

Use compiler flags for stack protection in GCC and Clang

Both GCC and Clang provide a wide range of compiler flags to prevent stack-based
attacks. Some of these flags relate to a specific kind of exploit. Others introduce
generic protection. And some flags give feedback like warnings and reports to the
user, providing a better understanding of the behavior of the stack program.
Depending on the attack scenario, code size constraints, and execution speed,
compilers provide a wide range of tools to address the attack.
