TODO LIST AND ISSUE TRACKER

As noted in the previous release we started to maintain a LTP TODO list in the
form GitHub issues, as expected the list is growing:

missing coverage

But more importantly we are starting to implement testcases based on that list,
recently we added the fsetxattr, fgetxattr, mlock2, prctl, and statx tests and
more is about to come in the near future.

We do have also list of reproducers to be turned into testcases:

reproducer

Lastly but not least I would like to ask everyone to contribute to these lists.
If you have a reproducer or notice missing coverage do not hesitate to open an
issue.

Since the last release 278 patches by 35 authors were merged.

Notable changes for this release include:

  • New tests for:

    • unshare(1) command
    • ioctl07 test for RNDGETENTCNT ioctl()
    • new network MACsec testcases
    • new network IPsec SCTP and DCCP testcases
  • New regression tests for:

  • Fixed tests:

    • brk01 (test rewritten from scratch)
    • sigwaitinfo01 (fixed and enabled)
    • openposix aio testcases (uninitialized aiocb)
    • many smaller fixes
  • Removed tests:

    • invalid openposix pthread_barrier_wait_6-1 test
    • tcp_cmds tests for rwho, echo, finger, and rdist.
  • The test library gained support to run a particular test against
    different filesystems including FUSE filesystems such as NTFS or exFAT. The
    mkfs and kernel/FUSE support for a particular filesystem must be in-place
    otherwise the tests will skip it automatically.

    Some of the filesystem specific syscall tests such as fallocate() are
    executed this way now. We also have a new test that fills up filesystem
    using several threads and expects the syscalls to fail gracefully.

  • The fuzzy synchronization library that is used to trigger races mostly in CVE
    testcases was rewritten to use one thread instead of starting a thread on
    each iteration, which is not only faster but also more stable since we
    introduce less random jitter to the timing measurements this way.

  • Various fixes and enhancements for the network testcases.

  • Support for NUMA API older than v2 was dropped from the testcases.

  • The configure script now correctly detects devel libraries on -m32 build.

  • Another large scale cleanup using coccinelle was done on the code base.

    We transformed patterns such as:

    if (scall(...) < 0)
    tst_brkm(TBROK, ...);

    into:

    SAFE_SCALL();

    Which will produce unified and more verbose error reporting in case
    that the call to scall() will fail.

  • The runltp script now lists test skipped by the skipfile parameter as skipped
    in the testrun results, these were missing from it previously.

  • 24 testcases were cleaned up and converted to the new test library

  • The usual amount of fixes all over the code base

Since the last release 290 patches by 39 authors were merged.

Notable changes for this release include:

  • New tests for:

    • copy_file_range()
    • splice() between pipes and sockets
    • splice() between two pipes
    • clone() with CLONE_NEWNET
    • msync() with mmaped file
    • getsockopt() with SO_PEERCRED
    • fanotify() with FAN_CLOEXEC
    • dynamic_debug tracing
    • basic gdb test
    • combination of OFD and POSIX locks on a file
  • New regression tests for:

    • fanotify() 96d41019e3ac and 05f0e38724e8
    • add_key() 5649645d725c
    • fcntl() 086e774a57fb
    • sched/autogroup 18f649ef3441
    • memcg https://bugzilla.redhat.com/show_bug.cgi?id=1168185
    • vdso permissions b6558c4a2378 and e5b97dde514f
    • keyctl() 63a0b0509e70
    • numa MPOL_PREFERRED policy 0867a57c
  • Removed tests:

    • long broken dmapi testsuite
  • 66 testcases were cleaned up and converted to the new test library

  • KSM (kernel samepage merging) test should be race-free now

  • So far if only small part of a test reported skipped status the overall
    test status was reported as skipped as well. Now if test reports both
    sucessful and skipped results the overall status is reported as suscessful.

  • Timer mesurement library code was introduced

    • all syscalls that use kernel timers are measured in a unified way
    • we take much more samples and use discarded mean to get rid of outliners
    • the threshold is now defined in the library and can be easily adjusted
    • for more information see:
      c459654
  • Also effort to convert CVE reproducers into LTP testcases started to gain momentum

    • It starts by introducing thread synchronization library that auto-tunes a
      spin-in-a-place delay so that we execute two critical sections of code at
      the same time, which makes tests based on races much more faster and
      stable in reproducing the bugs.

    • So far implemented CVE tests include:

      Note that a few of the testcases were implemented in the previous
      release as well but these were not counted as CVE related.

  • The ltp-pan testrunner that executes LTP testcases marks test start in kernel
    log, which helps with pairing LTP testcase with a kernel trace.

  • There is new step-by-step C test tutorial at:
    https://github.com/linux-test-project/ltp/wiki/C-Test-Case-Tutorial

  • A few EROFS related testcases now use read-only tmpfs instead of the loopback
    based device, which saves up to half of a minute of runtime per such testcase.
    The rest of such testcases will be converted after the release.

  • The nfsv4 locktest source has been translated from French.

  • Many fixes in numa testcases.

  • Many fixes in network testcases.

  • The usuall amount of fixes all over the codebase

Since the last release 169 patches by 24 authors were merged.

Notable changes are:

  • New C library test API that significantly eases test writing

    This is the end result of last few years of cleanups and fixes. Most of the
    common code has been moved to the library which both helps to avoid common
    mistakes and lets the programmer concentrate on test itself. It also fixed
    long standing problems with thread safety, simplified test result propagation
    from child processes, fixed problems with cleanup callback, etc. If you ever
    given up on writing a LTP testcase because the test API was incomplete and
    difficult to use you should really reconsider now.

    The old and new test API will coexistent for a while until all old testcases
    are converted, which will take quite some time. New test are written using
    the new API only.

    You can have a quick look at new/converted tests to get a feel for the new API:

    https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/syscalls/recvmsg/recvmsg02.c
    https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/syscalls/creat/creat06.c

    Or have a look at updated documentation at:

    https://github.com/linux-test-project/ltp/wiki/Test-Writing-Guidelines#22-writing-a-test-in-c

  • New syscall tests for:

    • request_key()
    • preadv()
    • pwritev(),
    • fcntl() + F_OFD_* locks
    • personality()
    • removexattr()
    • llistxattr()
    • epoll_pwait(),
    • epoll_wait()
    • open() + O_TMPFILE

    And regression tests for:

    • madvise() + MADV_WILLNEED
    • recvmsg() + MSG_PEEK
  • Rewritten network stress tests

  • New test for lsmod

  • Usual amount of fixes

    • fixed file corruptions with ltp-pan
    • added a few return value checks for fork() where the value is later passed
      to kill() resulting in call to kill(-1, ...) if fork() failed
    • a few more skipped test on Btrfs on unsupported/unimplemented functionality
    • fixed test result propagation in five fcntl testcases
    • much more...
