choice
    prompt "Enable stack buffer overflow detection"
    default  CC_STACKPROTECTOR_STRONG
    ---help---
    This option turns on the -fstack-protector GCC feature. This
    feature puts, at the beginning of functions, a canary value on
    the stack just before the return address, and validates
    the value just before actually returning.  Stack based buffer
    overflows (that need to overwrite this return address) now also
    overwrite the canary, which gets detected and the attack is then
    neutralized via a kernel panic.

    This feature requires gcc version 4.2 or above, or a distribution
    gcc with the feature backported. Older versions are automatically
    detected and for those versions, this configuration option is
    ignored. (and a warning is printed during bootup)
