◆ 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.

Initial value:
