2019-04-17selftests/kexec: update get_secureboot_modeMimi Zohar1-20/+66
The get_secureboot_mode() function unnecessarily requires both CONFIG_EFIVAR_FS and CONFIG_EFI_VARS to be enabled to determine if the system is booted in secure boot mode. On some systems the old EFI variable support is not enabled or, possibly, even implemented. This patch first checks the efivars filesystem for the SecureBoot and SetupMode flags, but falls back to using the old EFI variable support. The "secure_boot_file" and "setup_mode_file" couldn't be quoted due to globbing. This patch also removes the globbing.

2019-04-17selftests/kexec: kexec_file_load syscall testMimi Zohar1-0/+99
The kernel can be configured to verify PE signed kernel images, IMA kernel image signatures, both types of signatures, or none. This test verifies only properly signed kernel images are loaded into memory, based on the kernel configuration and runtime policies.

Define, update and move get_secureboot_mode() to a common file for use by other tests. Updated to check both the efivar SecureBoot-$(UUID) and SetupMode-$(UUID), based on Dave Young's review.
