selftests: firmware: return Kselftest Skip code for skipped tests

2018-05-30T21:21:52Z

When firmware test(s) get skipped because of unmet dependencies and/or unsupported configuration, it returns 0 which is treated as a pass by the Kselftest framework. This leads to false positive result even when the test could not be run. Change it to return kselftest skip code when a test gets skipped to clearly report that the test could not be run. Kselftest framework SKIP code is 4 and the framework prints appropriate messages to indicate that the test is skipped. Signed-off-by: Shuah Khan (Samsung OSG) Reviewed-by: Luis R.

test_firmware: modify custom fallback tests to use unique files

2018-03-20T08:28:47Z

Users of the custom firmware fallback interface is are not supposed to use the firmware cache interface, this can happen if for instance the one of the APIs which use the firmware cache is used first with one firmware file and then the request_firmware_nowait(uevent=false) API is used with the same file. We'll soon become strict about this on the firmware interface to reject such calls later, so correct the test scripts to avoid such uses as well. We address this on the tests scripts by simply using unique names when testing the custom fallback interface. Signed-off-by: Luis R. Rodriguez Signed-off-by: Greg Kroah-Hartman

test_firmware: expand on library with shared helpers

2018-03-20T08:28:47Z

This expands our library with as many things we could find which both scripts we use share. Signed-off-by: Luis R. Rodriguez Signed-off-by: Greg Kroah-Hartman

test_firmware: replace syfs fallback check with kconfig_has helper

2018-03-14T18:49:24Z

Now that we have a kconfig checker just use that instead of relying on testing a sysfs directory being present, since our requirements are spelled out. Acked-by: Kees Cook Signed-off-by: Luis R. Rodriguez Signed-off-by: Greg Kroah-Hartman

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.

test_firmware: add simple firmware firmware test library

2018-03-14T18:49:23Z

We'll expland on this later, for now just add basic module checker. While at it, move this all to use /bin/bash as we'll have much more flexibility with it. Signed-off-by: Luis R. Rodriguez Signed-off-by: Greg Kroah-Hartman

test_firmware: wrap custom sysfs load tests into helper

These can run on certain kernel configs. This will allow us later to enable these tests under the right kernel configurations. Signed-off-by: Luis R. Rodriguez Signed-off-by: Greg Kroah-Hartman
