Good news everyone,

the Linux Test Project test suite stable release for May 2025 has been
released.

Since the last release 282 patches by 33 authors were merged.

Patch review is what most of the projects struggle with and LTP is no
different. If you can spare some effort helping with the patch review is more
than welcomed.

    • fanotify03 test cases for permission events on children
    • pause01 tests now for more signals not just EINTR
    • setrlimit06 test resource limit64 for process

  • Removed tests

    • The test_controllers.sh is now disabled when v2 hierarchy is present
    • A few old and broken tests were removed from test_controllers.sh

  • kirk was updated to version 2.1 see the release notes at:
    https://github.com/linux-test-project/kirk/releases

  • New test catalogue generated from test metadata is live at:
    https://linux-test-project.readthedocs.io/en/latest/users/test_catalog.html

  • We have a new metadata extractor for a shell and first test that is parsed:
    https://linux-test-project.readthedocs.io/en/latest/users/test_catalog.html#vma05-sh

  • A few tests have been fixed not to be miscompiled by gcc-15

    • we had problems with changes in structure zero initializations where
      suddenly anonymous unions were not zero initialized anymore
    • and also with optimzer changes that now remove malloc() + free() pairs
      if the memmory is no touched between the calls

  • The tst_brk() behavior has finally been clarified and fixed, for details see
    LTP commit a1f8270 ("lib/tst_test.c: Fix tst_brk() handling").

  • New library test now have reproducible output that leaves out data that
    change between runs from the output, it's enabled with setting env variable
    LTP_REPRODUCIBLE_OUTPUT=1

  • Our github CI is now connected to patchwork and runs LTP
    compilation tests for patches:

    https://patchwork.ozlabs.org/project/ltp/list/

  • The LTP_SINGLE_FS_TYPE now honors test specific filesystem skiplists and thus
    can be used for general testing. There is new variable
    TST_FORCE_SINGLE_FS_TYPE that ignores skiplists and is supposed to be used
    for test development (which was previously the case for LTP_SINGLE_FS_TYPE).

  • The ipc runtest file that cointained only pipeio test was merged into
    syscalls runtest file

  • The horrible mess in testcases/kernel/mem/lib/ library was untangled into
    smaller pieces

  • 43 testcases were converted to the new test library

  • The usual amount of fixes and cleanups

NOTABLE CHANGES IN IMA TESTS

brought to you by Petr Vorel

  • Add support to load predefined example IMA policy with LTP_IMA_LOAD_POLICY=1
    environment variable.

    This allows to run tests which are otherwise skipped due required policy not
    being loaded. SUT should be rebooted after each IMA tests (unless
    CONFIG_IMA_WRITE_POLICY=y` the policy can be written only once or policies
    can influence each other).

  • Added additional ToMToU and open-writer violation tests (new in kernel v6.14)

  • IMA: Allow to disable LSM warnings and use it for IMA (avoid misleading warnings)

  • Add some example IMA policies
