ANDROID: update build files for tst_get_unused_port Change-Id: Icb459e198dba30fe873fca9c6488e4279f4ba4fe Signed-off-by: Steve Muckle <firstname.lastname@example.org>
Linux Test Project is a joint project started by SGI, OSDL and Bull developed and maintained by IBM, Cisco, Fujitsu, SUSE, Red Hat, Oracle and others. The project goal is to deliver tests to the open source community that validate the reliability, robustness, and stability of Linux.
The LTP testsuite contains a collection of tools for testing the Linux kernel and related features. Our goal is to improve the Linux kernel and system libraries by bringing test automation to the testing effort. Interested open source contributors are encouraged to join.

The discussion about the project happens at ltp mailing list: http://lists.linux.it/listinfo/ltp

Be careful with these tests!
Don't run them on production systems. Growfiles, doio, and iogen in particular stress the I/O capabilities of systems and while they should not cause problems on properly functioning systems, they are intended to find (or cause) problems.
If you have git, autoconf, automake, m4, the linux headers and the common developer packages installed, the chances are the following will work.
$ git clone https://github.com/linux-test-project/ltp.git $ cd ltp $ make autotools $ ./configure
Now you can continue either with compiling and running a single test or with compiling and installing the whole testsuite.
If you need to execute a single test you actually do not need to compile the whole LTP, if you want to run a syscall testcase following should work.
$ cd testcases/kernel/syscalls/foo $ make $ PATH=$PATH:$PWD ./foo01
Shell testcases are a bit more complicated since these need a path to a shell library as well as to compiled binary helpers, but generally following should work.
$ cd testcases/lib $ make $ cd ../commands/foo $ PATH=$PATH:$PWD:$PWD/../../lib/ ./foo01.sh
Open Posix Testsuite has it's own build system which needs Makefiles to be generated first, then compilation should work in subdirectories as well.
$ cd testcases/open_posix_testsuite/ $ make generate-makefiles $ cd conformance/interfaces/foo $ make $ ./foo_1-1.run-test
$ make $ make install
This will install LTP to
Some tests will be disabled if the configure script can not find their build dependencies.
TCONFdue to a missing component, check the
To run all the test suites
$ cd /opt/ltp $ ./runltp
Note that many test cases have to be executed as root.
To run a particular test suite
$ ./runltp -f syscalls
To run all tests with
madvise in the name
$ ./runltp -f syscalls -s madvise
$ ./runltp --help
Test suites (e.g. syscalls) are defined in the runtest directory. Each file contains a list of test cases in a simple format, see doc/ltp-run-files.txt.
Each test case has its own executable or script, these can be executed directly
Some have arguments
$ testcases/bin/fork13 -i 37
The vast majority of test cases accept the -h (help) switch
$ testcases/bin/ioctl01 -h
Many require certain environment variables to be set
$ LTPROOT=/opt/ltp PATH="$PATH:$LTPROOT/testcases/bin" testcases/bin/wc01.sh
Most commonly, the path variable needs to be set and also
LTPROOT, but there are a number of other variables,
runltp usually sets these for you.
Note that all shell scripts need the
PATH to be set. However this is not limited to shell scripts, many C based tests need environment variables as well.
