Use compiler flags for stack protection in GCC and Clang
|
Shuah Khan
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. https://developers.redhat.com/articles/2022/06/02/use-compiler-flags-stack-protection-gcc-and-clang# thanks, -- Shuah |

This is excellent, Shuah, and is very much aligned with previous work on kernel configurations and compiler settings for stack protection.
Let's deep dive into these settings in this weeks LFSCS meeting, to understand how this ties in with:
