837 | + |
838 | + Provide kuser helpers in the vector page. The kernel provides |
839 | + helper code to userspace in read only form at a fixed location |
840 | + in the high vector page to allow userspace to be independent of |
841 | + the CPU type fitted to the system. This permits binaries to be |
842 | + run on ARMv4 through to ARMv7 without modification. |
843 | + |
844 | + However, the fixed address nature of these helpers can be used |
845 | + by ROP (return orientated programming) authors when creating |
846 | + exploits. |
847 | + |
848 | + If all of the binaries and libraries which run on your platform |
849 | + are built specifically for your platform, and make no use of |
850 | + these helpers, then you can turn this option off. However, |
851 | + when such an binary or library is run, it will receive a SIGILL |
852 | + signal, which will terminate the program. |
853 | + |
854 | + Say N here only if you are absolutely certain that you do not |
855 | + need these helpers; otherwise, the safe option is to say Y. |
