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: https://github.com/linux-test-project/ltp/commit/c459654db64cd29177a382ab178fdd5ad59664e4 * 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 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 What havent't made it to this release: -------------------------------------- * A patchset that adds test library support to allow for filesystem related syscalls, such as fallocate(), to be executed against all supported filesystems. * Fixes and speed ups for the CVE synchronization library and a few CVE reproducers. Downloads and links: -------------------- The latest version of the test-suite contains 3000+ tests for the Linux and can be downloaded at: https://github.com/linux-test-project/ltp/releases/tag/20170930 The project pages as well as GIT repository are hosted on GitHub: https://github.com/linux-test-project/ltp http://linux-test-project.github.io/ If you ever wondered how to write a LTP testcase, don't miss our developer documentation at: https://github.com/linux-test-project/ltp/wiki/C-Test-Case-Tutorial https://github.com/linux-test-project/ltp/wiki/Test-Writing-Guidelines https://github.com/linux-test-project/ltp/wiki/BuildSystem Patches, new tests, bugs, comments or questions should go to to our mailing list at ltp@lists.linux.it. -- Cyril Hrubis chrubis@suse.cz From mboxrd@z Thu Jan 1 00:00:00 1970 From: Cyril Hrubis Date: Fri, 29 Sep 2017 17:31:24 +0200 Subject: [LTP] [ANNOUNCE] The Linux Test Project has been released for SEPTEMBER 2017 Message-ID: <20170929153123.GB1886@rei> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ltp@lists.linux.it Good news everyone, the Linux Test Project test suite stable release for *September 2017* has been released.
