Revert "selftests: firmware: add CONFIG_FW_LOADER_USER_HELPER_FALLBACK to config"

2019-02-08T12:00:43Z

This reverts commit 7492902e8d22b568463897fa967c0886764cf034. The commit tried to address an issue discovered by Dan where he got a message saying: 'usermode helper disabled so ignoring test'. Dans's commit is forcing CONFIG_FW_LOADER_USER_HELPER_FALLBACK but just having CONFIG_FW_LOADER_USER_HELPER suffices to emulate the_FALLBACK functionality. Dan's commit is trying to fix an issue which is hidden from a previous commit. That issue will be addressed properly next.

selftests: firmware: add CONFIG_FW_LOADER_USER_HELPER_FALLBACK to config

CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y is required for fw_fallback.sh. Without it, fw_fallback.sh fails with 'usermode helper disabled so ignoring test'. Enable the config in selftest so that it gets built by default. Signed-off-by: Dan Rue Acked-by: Kees Cook Signed-off-by: Shuah Khan

test_firmware: enable custom fallback testing on limited kernel configs

2018-03-14T18:49:24Z

When a kernel is not built with: CONFIG_HAS_FW_LOADER_USER_HELPER_FALLBACK=y We don't currently enable testing fw_fallback.sh. For kernels that still enable the fallback mechanism, its possible to use the async request firmware API call request_firmware_nowait() using the custom interface to use the fallback mechanism, so we should be able to test this but we currently cannot. We can enable testing without CONFIG_HAS_FW_LOADER_USER_HELPER_FALLBACK=y by relying on /proc/config.gz (CONFIG_IKCONFIG_PROC), if present. If you don't have this we'll have no option but to rely on old heuristics for now. We stuff the new kconfig_has() helper into our shared library as we'll later expando on its use elsewhere.

selftests: create test-specific kconfig fragments

2016-02-25T16:47:52Z

Create the config file in each directory of testcase which need more kernel configuration than the default defconfig. User could use these configs with merge_config.sh script: Enable config for specific testcase: (export ARCH=xxx #for cross compiling) ./scripts/kconfig/merge_config.sh .config \ tools/testing/selftests/xxx/config Enable configs for all testcases: (export ARCH=xxx #for cross compiling) ./scripts/kconfig/merge_config.sh .config \ tools/testing/selftests/*/config Signed-off-by: Bamvor Jian Zhang Reviewed-by: Shuah Khan Signed-off-by: Shuah Khan
