-config CC_STACKPROTECTOR
-       bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"
-       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.
