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.

LTP 20180118

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:

  • CVE-2017-5754 aka meltdown
  • CVE-2017-12193 (test add_key04)
  • CVE-2017-15299 and CVE-2017-15951 (test request_key03)
  • CVE-2017-7308 (test setsockopt02)
  • CVE-2016-9604 (test keyctl08)
  • CVE-2017-15537 (test ptrace07)
  • CVE-2017-12192 (test keyctl07)
  • add_key03 regression test for kernel commit 237bbd29f7a0
  • keyctl06 regression test for kernel commit e645016abc80

• 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

LTP 20170929

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:

    • CVE-2011-0999 transparent hugepages used wrongly for args/env
    • CVE-2011-2183 NULL pointer dereference in ksm_do_scan()
    • CVE-2011-2496 address overflow in mremap()
    • CVE-2012-0957 uname26 memory leak
    • CVE-2014-0196 PTY echo race
    • CVE-2015-0235 buffer overflow in gethostbyname_r()
    • CVE-2015-7550 race between keyctl_read() and keyctl_revoke()
    • CVE-2016-4470 uninitialized variable in key_reject_and_link()
    • CVE-2016-5195 aka dirtyc0w
    • CVE-2016-7042 crash in /proc/keys show function
    • CVE-2016-7117 use after free between recvmmsg() and close()
    • CVE-2016-10044 mark AIO pseudo-fs noexec
    • CVE-2017-2618 off-by-one in setprocattr
    • CVE-2017-2671 missing rwlock in ping_unhashed()
    • CVE-2017-5669 NULL page mapped with shmat() and SHM_RND
    • CVE-2017-6951 NULL dereference in request_key()
    • CVE-2017-7472 thread keyring memory leak
    • CVE-2017-1000364 aka stack_clash

    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

LTP 20170516

LTP 20170116

Since the last release 211 patches by 28 authors were merged.

Notable changes:

• New testcases for:
  • flistxattr()
  • listxattr()
  • llistxattr()
  • getpriority()
  • setpriority()
  • sendto()
  • dirtyc0w
  • vti and geneve tunnel tests (network tests)
• New shell test library was added and many old and broken tests were
  rewritten to make use of it
• 36 syscall testcases were converted to the new library
• Many cases of bashism were fixed
• Experimental support for network namespaces has been added into network
  tests, which means that these test can now be optionally executed on a
  single testing machine
• LTP compiled for 32bit should now run flawlessly on 64bit kernel
  which is useful for testing the 32bit compat syscall interface
• Usuall amount of cleanups, fixes and speedups

LTP 20160920

Since the last release 236 patches by 28 authors were merged.

Notable changes:

o New testcases

• tracepath, clockdiff, arpping, ping, wc, insmod
• ftrace
• access()
• fallocate(FALLOC_FL_INSTERT_RANGE)
• kcmp()
• lgetxattr()
• sched_setscheduler()
• epoll_ctl()
• sbrk() regression test
• dio_sparse added direct I/O regression test
  (https://patchwork.ozlabs.org/patch/622065/)

o Rewritten/cleaned up tests

• waitpid syscall testcases
• NFS tests
• ftrace tests

o More work on memory cgroup testcases

• a lot of cleanups, big tests were split into smaller ones
• implemented proper synchronization primitives between processes
  which saves a few minutes on the test execution time

o More work on the new test API

• test is executed in child processes, parent process watches for timeout,
  does cleanup, reports results, etc.
• Ctrl+C kills all subprocesses correctly and the parent process runs cleanup
• new command line option parsing helpers
• 25 testcases were cleaned up and rewritten to use the new test API

o New EXPECT_PASS and EXPECT_FAIL helpers in shell library

o New shell wrappers for checkpoint (futex based) synchronization primitives

o New tst_su wrapper (that makes sure that path to LTP binaries is in $PATH)

o Open Posix Testsuite changes

• parallel build has been fixed
• the build process now uses the top level configure parameters
  (CC, CFLAGS, LDLIBS, LDFLAGS)

o And usuall amount of cleanups, fixes, and speedups.

LTP 20160510

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()

  • personality()
  • removexattr()
  • llistxattr()
  • epoll_pwait(),
  • epoll_wait()

  And regression tests for:

  • madvise() + MADV_WILLNEED
  • recvmsg() + MSG_PEEK

    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...
