10 prompt "Filter access to /dev/mem"
12 This option restricts access to /dev/mem. If this option is
13 disabled, you allow userspace access to all memory, including
14 kernel and userspace memory. Accidental memory access is likely
16 Memory access is required for experts who want to debug the kernel.
18 If you are unsure, say Y.
20 config DEBUG_STRICT_USER_COPY_CHECKS
22 prompt "Strict user copy size checks"
24 Enabling this option turns a certain set of sanity checks for user
25 copy operations into compile time warnings.
27 The copy_from_user() etc checks are there to help test if there
28 are sufficient security checks on the length argument of
29 the copy operation, by having gcc prove that the argument is
32 If unsure, or if you run an older (pre 4.4) gcc, say N.
35 bool "Export kernel pagetable layout to userspace via debugfs"
36 depends on DEBUG_KERNEL
39 Say Y here if you want to show the kernel pagetable layout in a
40 debugfs file. This information is only useful for kernel developers
41 who are working in architecture specific areas of the kernel.
42 It is probably not a good idea to enable this feature in a production
