+         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.
