Peter,

If I understand correctly (by inspecting clang code), the stack 
protector is off by default. Do you have link to Gentoo build
page to show how they enable stack protector? cmake config or
a private patch?

Jose,

How gcc-bpf handle stack protector? The compiler just disables
stack protector for bpf target?
