└─>Enable kuser helpers in vector page
In linux kernel since version 3.10 (release Date: 2013-06-30)
Warning: disabling this option may break user programs.
Provide kuser helpers in the vector page. The kernel provides
helper code to userspace in read only form at a fixed location
in the high vector page to allow userspace to be independent of
the CPU type fitted to the system. This permits binaries to be
run on ARMv4 through to ARMv7 without modification.
See <a href="https://www.kernel.org/doc/Documentation/arch/arm/kernel_user_helpers.rst">Documentation/arch/arm/kernel_user_helpers.rst</a> for details.
However, the fixed address nature of these helpers can be used
by ROP (return orientated programming) authors when creating
exploits.
If all of the binaries and libraries which run on your platform
are built specifically for your platform, and make no use of
these helpers, then you can turn this option off to hinder
such exploits. However, in that case, if a binary or library
relying on those helpers is run, it will receive a SIGILL signal,
which will terminate the program.
Say N here only if you are absolutely certain that you do not
need these helpers; otherwise, the safe option is to say Y.
