- prompt "Filter access to /dev/mem"
- ---help---
- This option restricts access to /dev/mem. If this option is
- disabled, you allow userspace access to all memory, including
- kernel and userspace memory. Accidental memory access is likely
- to be disastrous.
- Memory access is required for experts who want to debug the kernel.
- If you are unsure, say Y.

- prompt "Strict user copy size checks"
- ---help---
- Enabling this option turns a certain set of sanity checks for user
- copy operations into compile time warnings.
- The copy_from_user() etc checks are there to help test if there
- are sufficient security checks on the length argument of
- the copy operation, by having gcc prove that the argument is
- within bounds.
- If unsure, or if you run an older (pre 4.4) gcc, say N.
