313    ---help---
314    This option turns on the -fstack-protector GCC feature. This
315    feature puts, at the beginning of functions, a canary value on
316    the stack just before the return address, and validates
317    the value just before actually returning.  Stack based buffer
318    overflows (that need to overwrite this return address) now also
319    overwrite the canary, which gets detected and the attack is then
320    neutralized via a kernel panic.
321
322    This feature requires gcc version 4.2 or above, or a distribution
323    gcc with the feature backported. Older versions are automatically
324    detected and for those versions, this configuration option is
325    ignored. (and a warning is printed during bootup)
