Subject: [PATCH v14 00/22] selftests, powerpc, x86 : Memory Protection Keys
Date: Tue, 17 Jul 2018 06:49:03 -0700 [thread overview]
Message-ID: <1531835365-32387-1-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 and on x86.
History:
-------
version 14:
(1) incorporated another round of comments from Dave Hansen.
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.

selftests/x86: Move protecton key selftest to arch neutral directory
selftests/vm: rename all references to pkru to a generic name
selftests/vm: move generic definitions to header file
selftests/vm: typecast the pkey register

violation

selftests/vm: sub-page allocator
selftests/vm: test correct behavior of pkey-0
Thiago Jung Bauermann (2):
