2352 help
2353 This option turns on the -fstack-protector GCC feature. This
2354 feature puts, at the beginning of functions, a canary value on
2355 the stack just before the return address, and validates
2356 the value just before actually returning. Stack based buffer
2357 overflows (that need to overwrite this return address) now also
2358 overwrite the canary, which gets detected and the attack is then
2359 neutralized via a kernel panic.

4 * mode and when in input mode will contain the value at the input. The config
