Subject: [ANNOUNCE] The Linux Test Project has been released for January 2026

Good news everyone,

the Linux Test Project test suite stable release for *January 2026* has been
released.

Since the last release 164 patches by 29 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.

NOTABLE CHANGES
===============

* New tests

  - file_attr05 Check for EOPNOTSUPP when filesystem does not support FSX operations.
                Regression test for 474b155adf392 ("fs: make vfs_fileattr_[get|set] return -EOPNOTSUPP")
  - userfaultfd05 Test for UFFDIO_WRITEPROTECT
  - userfaultfd04 Test for UFFDIO_ZEROPAGE
  - userfaultfd03 Test for /dev/userfaultfd
  - userfaultfd02 Test for UFFDIO_MOVE
  - userfaultfd01 Test for UFFD_USER_MODE_ONLY
  - clone10 Test for CLONE_SETTLS
  - clone11, clone304 Tests for more EPERM conditions
  - name_to_handle_at03 Tests for AT_HANDLE_FID

* Increased coverage

  - fanotify24 Added a regression test for 28bba2c2935e2 ("fsnotify: Pass correct offset to fsnotify_mmap_perm()")

* Rewritten and updated tests

  - lio_listio_2-1, aio_cancel_5-1 Were rewritten to actually block while writing and not relying on a chance.

  - Tests that compile and load kernel modules now properly skip the test when kernel is Lockdown/Secure boot.

  - swapon03 Now does not try to calculate the exact maximal number of swap files based on kernel config.

  - readahead02: Was fixed to wait for the readahead to happen and also updated
                 to use mincore() instead of system wide I/O counters.

  - ima_conditionals.sh Was split into four tests so that subset of the tests
                        is not skipped without CONFIG_IMA_WRITE_POLICY=y.

* New shell tst_runas.c helper

  We are replacing the use of sudo with simpler tst_runas.c helper that changes
  UID and GID before executing a command. This makes tests less likely to fail
  because of system restrictions on sudo (such as setting /usr/sbin/nologin as
  a login shell).

* Openposix tests had to be updated with new invalid clock IDs

  Since the addition of CONFIG_POSIX_AUX_CLOCK the clock id 17 was not invalid anymore.

* New shell library now supports setting runtime

* New documentation:
  - https://linux-test-project.readthedocs.io/en/latest/developers/ground_rules.html
  - https://linux-test-project.readthedocs.io/en/latest/developers/api_c_tests.html#process-state
  - https://linux-test-project.readthedocs.io/en/latest/developers/api_c_tests.html#saving-and-restoring-proc-sys-values

* Kirk was updated to v3.2.1

+ The usual amount of fixes and cleanups
