Hi folks,
I have a PR up in edk2: https://github.com/tianocore/edk2/pull/5957
that adds Stack Cookie support to MSVC and GCC built IA32, X64, ARM,
and AARCH64 binaries. This corresponds to /GS for MSVC and
-fstack-protector for gcc. ARM/AARCH64 stack cookie support already
existed in edk2, but this greatly expands it by adding support for
build time and runtime stack cookies. By default, all binaries will
link against the null stack cookie instance, which does not take
action on stack overruns. Please see the PR details for more
information, including links for more details on how stack
cookies support better security and safety.
Please leave any comments on the PR.
Thanks,
Oliver
