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
