Subject: [PATCH] selftests: firmware: Fix it to do root uid check and skip
Date: Thu, 12 Dec 2019 18:56:06 -0700 [thread overview]
Message-ID: <20191213015606.23058-1-skhan@linuxfoundation.org> (raw)
firmware attempts to load test modules that require root access
and fail. Fix it to check for root uid and exit with skip code
instead.
Before this fix:
selftests: firmware: fw_run_tests.sh
modprobe: ERROR: could not insert 'test_firmware': Operation not permitted
You must have the following enabled in your kernel:
CONFIG_TEST_FIRMWARE=y
CONFIG_FW_LOADER=y
CONFIG_FW_LOADER_USER_HELPER=y
CONFIG_IKCONFIG=y
CONFIG_IKCONFIG_PROC=y
not ok 1 selftests: firmware: fw_run_tests.sh # SKIP
With this fix:
selftests: firmware: fw_run_tests.sh
skip all tests: must be run as root
not ok 1 selftests: firmware: fw_run_tests.sh # SKIP
