Rik van Riel 7cd815bce8 fork,random: use get_random_canary() to set tsk->stack_canary ... Use the ascii-armor canary to prevent unterminated C string overflows from being able to successfully overwrite the canary, even if they somehow obtain the canary value. Inspired by execshield ascii-armor and Daniel Micay's linux-hardened tree.
