Subject: [PATCH v13 00/24] selftests, powerpc, x86 : Memory Protection Keys
Date: Wed, 13 Jun 2018 17:44:51 -0700	[thread overview]
Message-ID: <1528937115-10132-1-git-send-email-linuxram@us.ibm.com> (raw)

Memory protection keys enables an application to protect its address space from
inadvertent access by its own code.

This feature is now enabled on powerpc architecture and integrated in
4.16-rc1.  The patches move the selftests to arch neutral directory
and enhance their test coverage.

Test
----
Verified for correctness on powerpc. Need help verifying on x86.
Compiles on x86.

History:
-------

version 13:
	(1) Incorporated comments for Dave Hansen.
	(2)   Added one more test for correct pkey-0 behavior.

version 12:
        (1) fixed the offset of pkey field in the siginfo structure for
	    x86_64 and powerpc. And tries to use the actual field
	    if the headers have it defined.

version 11:
	(1) fixed a deadlock in the ptrace testcase.

version 10 and prior:
	(1) moved the testcase to arch neutral directory
	(2) split the changes into incremental patches.
