| 699config CC_STACKPROTECTOR 700 bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)" 701 depends on SUPERH32 702 help 703 This option turns on the -fstack-protector GCC feature. This 704 feature puts, at the beginning of functions, a canary value on 705 the stack just before the return address, and validates 706 the value just before actually returning. Stack based buffer 707 overflows (that need to overwrite this return address) now also 708 overwrite the canary, which gets detected and the attack is then 709 neutralized via a kernel panic. 710 711 This feature requires gcc version 4.2 or above. 712 |
