- MPX provides hardware features that can be used in
- conjunction with compiler-instrumented code to check
- memory references. It is designed to detect buffer
- overflow or underflow bugs.
-
- This option enables running applications which are
- instrumented or otherwise use MPX. It does not use MPX
- itself inside the kernel or to protect the kernel
- against bad memory references.
-
- Enabling this option will make the kernel larger:
- ~8k of kernel text and 36 bytes of data on a 64-bit
- defconfig. It adds a long to the 'mm_struct' which
- will increase the kernel memory overhead of each
- process and adds some branches to paths used during
- exec() and munmap().
-
- For details, see Documentation/x86/intel_mpx.rst
-
- If unsure, say N.
