Function Documentation

declscope()

declscope

(

C

)

Global stack-protector guard value read by every -fstack-protector function prologue/epilogue.

ssp_init()

void zxfoundation::base::cxxrtse::cxxabi::ssp_init ( )

exportnoexcept

Install the kernel-wide stack-protector guard entropy.

Note

One value is computed once on the BSP and used kernel-wide; APs do not recompute it. This is what makes the guard migration-safe across CPUs (see the __stack_chk_guard rationale above).

stack_guard()

auto zxfoundation::base::cxxrtse::cxxabi::stack_guard ( ) ->u64

nodiscardexportnoexcept

Read the active kernel-wide stack-protector guard value.

Returns

The current __stack_chk_guard.
