testing: use the copyleft-next-0.3.1 SPDX tag

2022-11-08T14:44:02+00:00

Two selftests drivers exist under the copyleft-next license. These drivers were added prior to SPDX practice taking full swing in the kernel. Now that we have an SPDX tag for copyleft-next-0.3.1 documented, embrace it and remove the boiler plate.

selftests: kmod: use variable NAME in kmod_test_0001()

2020-08-12T17:58:01+00:00

Patch series "kmod/umh: a few fixes". Tiezhu Yang had sent out a patch set with a slew of kmod selftest fixes, and one patch which modified kmod to return 254 when a module was not found. This opened up pandora's box about why that was being used for and low and behold its because when UMH_WAIT_PROC is used we call a kernel_wait4() call but have never unwrapped the error code. The commit log for that fix details the rationale for the approach taken. I'd appreciate some review on that, in particular nfs folks as it seems a case was never really hit before. This patch (of 5): Use the variable NAME instead of "\000" directly in kmod_test_0001().

selftests: kmod: Add module address visibility test

Replace HTTP links with HTTPS ones: KMOD KERNEL MODULE LOADER - USERMODE HELPER

2020-07-09T20:16:41+00:00

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

selftests: kmod: test disabling module autoloading

2020-04-10T22:36:22+00:00

Test that request_module() fails with -ENOENT when /proc/sys/kernel/modprobe contains (a) a nonexistent path, and (b) an empty path. Case (b) is a regression test for the patch "kmod: make request_module() return an error when autoloading is disabled". Tested with 'kmod.sh -t 0010 && kmod.sh -t 0011', and also simply with 'kmod.sh' to run all kmod tests.

selftests: kmod: fix handling test numbers above 9

2020-04-10T22:36:22+00:00

get_test_count() and get_test_enabled() were broken for test numbers above 9 due to awk interpreting a field specification like '$0010' as octal rather than decimal. Fix it by stripping the leading zeroes.

selftests: kmod: return Kselftest Skip code for skipped tests

2018-05-30T21:21:53+00:00

When kmod test is 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. It returns fail in some cases when test is skipped. Either way, it is incorrect and incosnistent reporting. 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.
