General informations

• prompt:
• type: bool
• depends on: (none)
• defined in arch/Kconfig
• found in Linux kernels: 5.13–5.19, 6.0–6.8, 6.9-rc+HEAD

Help text

An arch should select this symbol if it can support kernel stack offset randomization with calls to add_random_kstack_offset() during syscall entry and choose_random_kstack_offset() during syscall exit. Careful removal of -fstack-protector-strong and -fstack-protector should also be applied to the entry code and closely examined, as the artificial stack bump looks like an array to the compiler, so it will attempt to add canary checks regardless of the static branch state.
