@wphuhn-intel noted during the C/C++ Compiler BP Call on 2024-09-19 that
PT_GNU_STACK
must be present on binaries on 32-bit x86 even on more recent kernels than 5.8 for the resulting process to benefit from execution prevention for program data, not only the stack.This PR adds a note on this in the
-Wl,-z,noexecstack
section, as an example for why specifying the option explicitly is recommended.
