  - CAN tests were cleaned up and converted to the new library
Integrity Measurement Architecture (IMA)
- new SELinux measurement tests
- fixes
Added new library for managing network interfaces over netlink
Added new library for cgroup discovery and management
- this is a big leap forward for cgroup testing
- greatly simplifies testscases as the library gracefully handles v1/v2
  split configurations that are unfortunatelly still common on recent systems
- first few tests were converted to use the library
- more tests are in the queue
Fixed timeouts in shell test library
- ensure that all child processes are killed on timeout as well
- runs a cleanup after timeout
The fuzzy sync library was fixed to yield() on single CPU systems
- which fixed test timeouts on single CPU systems
- self tests for the library where implemented where we check that races we
  crafted into the code are triggered correctly by the library even on single
  CPU systems
Fixed kernel module detection on BusyBox
Open Posix Testsuite now use $TMPDIR instead of previously hardcoded /tmp
LTP should now produce reproducible build after a few fixes to the buildsystem and libs
The documentation generated from the test sources was improved, you can check
out the generated documentation pages for this release at:
http://linux-test-project.github.io/metadata/metadata.asciidoctor.html
Also have a look at a few nice test documentation examples:
http://linux-test-project.github.io/metadata/metadata.asciidoctor.html#acct02
http://linux-test-project.github.io/metadata/metadata.asciidoctor.html#bpf_prog05
http://linux-test-project.github.io/metadata/metadata.asciidoctor.html#semctl09
We also wrote down a document about the oldest supported kernel and libc, see:
https://github.com/linux-test-project/ltp/wiki/Supported-kernel,-libc,-toolchain-versions
