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.
|
||||
|
||||
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. However,
|
||||
when such an binary or library 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.
