Subject: [PATCH 0/3] selftest/ima: fail kexec_load syscall 
Date:   Mon, 19 Nov 2018 14:56:08 -0500
Message-Id: <1542657371-7019-1-git-send-email-zohar@linux.ibm.com>

Precedence: bulk

The "ima: add support for arch specific policies" patch set introduced
architecture specific policies, including an x86 policy which prevents
loading a kernel image via the kexec_load syscall.

This patch set preq's that patch set, adding a missing kexec_load
syscall failure message, extending the existing support for detecting
secureboot mode, and defining a kexec_load syscall selftest to
simplify testing.

To run the kexec_load test requires root privileges.  Execute:
	"sudo make TARGETS=ima kselftest".

With secure boot enabled, the kexec_load fails, but the test
succeeds.

selftests: ima: test_kexec_load.sh
========================================
./test_kexec_load.sh: kexec_load failed [PASS]
ok 1..1 selftests: ima: test_kexec_load.sh [PASS]
