selftests: lib: remove strscpy test

2024-08-01T19:55:33+00:00

The strscpy test loads test_strscpy module for testing. But test_strscpy
was converted to Kunit (see fixes). Hence remove strscpy.

lib: make a test module with set/clear bit

2020-06-05T02:06:25+00:00

Test some bit clears/sets to make sure assembly doesn't change, and that
the set_bit and clear_bit functions work and don't cause sparse warnings.

Instruct Kbuild to build this file with extra warning level -Wextra, to
catch new issues, and also doesn't hurt to build with C=1.

This was used to test changes to arch/x86/include/asm/bitops.h.

In particular, sparse (C=1) was very concerned when the last bit before a
natural boundary, like 7, or 31, was being tested, as this causes sign
extension (0xffffff7f) for instance when clearing bit 7.

Recommended usage:

  make defconfig
  scripts/config -m CONFIG_TEST_BITOPS
  make modules_prepare
  make C=1 W=1 lib/test_bitops.ko
  objdump -S -d lib/test_bitops.ko
  insmod lib/test_bitops.ko
  rmmod lib/test_bitops.ko

, there should be no compiler/sparse warnings and no
error messages in log.

selftests: Move kselftest_module.sh into kselftest/

2019-11-07T21:46:08+00:00

The kselftest_module.sh file was not being installed by the Makefile
"install" target, rendering the lib/*.sh tests nonfunction. This fixes
that and takes the opportunity to move it into the kselftest/ subdirectory
which is where the kselftest infrastructure bits are collecting.

kselftest: Add test runner creation script

2019-04-08T22:44:11+00:00

Currently if we wish to use kselftest to run tests within a kernel
module we write a small script to load/unload and do error reporting.
There are a bunch of these under tools/testing/selftests/lib/ that are
all identical except for the test name.  We can reduce code duplication
and improve maintainability if we have one version of this.  However
kselftest requires an executable for each test.  We can move all the
script logic to a central script then have each individual test script
call the main script.

Oneliner to call kselftest_module.sh courtesy of Kees, thanks!

Add test runner creation script.  Convert
tools/testing/selftests/lib/*.sh to use new test creation script.

Testing
-------

Configure kselftests for lib/ then build and boot kernel.  Then run
kselftests as follows:

  $ cd /path/to/kernel/tree
  $ sudo make O=$output_path -C tools/testing/selftests TARGETS="lib" run_tests

and also

  $ cd /path/to/kernel/tree
  $ cd tools/testing/selftests
  $ sudo make O=$output_path TARGETS="lib" run_tests

and also

  $ cd /path/to/kernel/tree
  $ cd tools/testing/selftests
  $ sudo make TARGETS="lib" run_tests

selftests: lib: return Kselftest Skip code for skipped tests

2018-05-30T21:29:06+00:00

When lib test(s) is skipped because of unmet dependencies and/or
unsupported configuration, it returns non-zero value hich is treated
as a fail by the Kselftest framework. This leads to false negative 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.
