2016-01-26test.sh: Fix ROD redirection && callersCyril Hrubis
The ROD could not detect failures when the output was redirected into a file since the redirection was handled in the caller. For example doing: ROD echo a > /proc/cpus Would have worked just fine since the $@ in ROD function would contain only 'echo a'. Moreover doing: ROD false > tmpfile Would end up writing the error message to the tmpfile instead of the stdout. For this reasons the ROD has been changed to take special char \> as redirection operator. The only difference is that the > in the ROD command must be prefixed with \ so that it's passed along with the file to the ROD function. The $@ there is split on '>' and the redirection is done inside ROD function which fixes the errors described above.

2016-01-25controllers: cgroup_fj: Partial rewriteCyril Hrubis
Most of the functionality has been preserved. The main changes are: --------------------- Changed the testcases to use test.sh. Got rid of bashisms. The code is much more clean now :). The testcases no longer move all system processes into test subgroups which has proven to be troublesome for a few reasons. The main one was that when the testcase failed to clean up the system ended up half-functioning. The other was that this did not scale up reasonably as the runtime depends on number of processes and there were systems (with large amounts of CPUs and RAM and slightly older kernel) where only one of the stress tests took about hour. The stress tests should now take at most a few minutes each (at least they all took less than five minutes on slowest machine I had) and the run should be < 1h on reasonably fast machine. I've also removed the ns namespace testcases since I haven't tested these and discussion on ML suggested that ns namespace needs some extra steps. We may add them later. Another TODO is proper release agent testing, but since the original code didn't actually test it (the code checked if release agent could be set but that was all it tested) I've omitted it for now as well.

2016-01-21test.sh: Add tst_umount(), use it in mkfs and df testsCyril Hrubis
For the same reason we added it to the C library in 420add2. To quote the commit to the C library: "Various desktop deamons (gvfsd-trash is known for that) may be stupid enough to probe all newly mounted filesystem which results in umount(2) failing with EBUSY." The shell version does also check if the device is actually mounted and do not attempt to do umount if it's not so it could be directly used in cleanups. This commit also makes use of the tst_umount() in mkfs01.sh and df01.sh which has been found failing rarely. Signed-off-by: Cyril Hrubis <chrubis@suse.cz>

2016-01-19controllers/pids.sh: A few fixesCyril Hrubis
* Add executable flag to the pids.sh script * Redirect stderr to stdout for kill pids_task2 * Fix the limit for third testcase: Since we start a pids_task1 which tries to do a fork and expects to succeed the limit must be lesser number of attached tasks - 2. It makes more sense to increase the parameter by two rather than decreasing it since the test 'pids.sh 3 1' fails because it tries to start -1 tasks. The runtest file is updated accordingly.

2016-01-14kernel/input: Redo open_device()Cyril Hrubis
The opendir approach si prone to race conditions. Since if the newly created input char device was missing at the time we called opendir() we will never try to open it. This changes the function to open /dev/input/event[0-100] blindly instead. We also retry opening the device with a short usleep() in between to make sure we do not fail in cases where the device creation is delayed substantially.

2016-01-13build: regen.sh (linux_syscall_numbers.h): Fix raceCyril Hrubis
The file is set as global make dependency in testcase.mk and the problem is that the regen.sh script still takes 0.2s on reasonably modern machine and because of that the parallel make can run the script several times since the file is created at the very end of the script. I've seen build failures where the script was stared from both tools/Makefile and testcases/kernel/Makefile and the build failed since the result was corrupted header. So this patch adds '@touch linux_syscall_numbers.h' before we start the regen.sh script so that the rest of make processes will see the goal as finished and wouldn't start the regen.sh script while one instance is allready running.

2016-01-07module.mk: Skip module build properlyCyril Hrubis
As it was the foo.ko module may end up in MAKE_TARGETS (for any make goal) even if WITH_MODULES was set to 'no' if there was any file with .ko suffix left in the directory. Since the SKIP was set to 2 incorrectly in that case. Not that this was a serious bug but it caused quite a lot of head scratching before I figured out why the build system is even trying to build the modules when kernel-devel package wasn't installed and the configure set WITH_MODULES to 'no'. Now we explictilty add the '*.ko' into MAKE_TARGETS only for install and clean goals instead of playing with different SKIP variable values. Signed-off-by: Cyril Hrubis <chrubis@suse.cz>

shmget()/shmat() fails to allocate huge pages shared memory segment with EINVAL if its size is not in the range [ N*HUGE_PAGE_SIZE - 4095, N*HUGE_PAGE_SIZE ]. This is a problem in the memory segment size round up algorithm. The requested size is rounded up to PAGE_SIZE (4096), but if this roundup does not match HUGE_PAGE_SIZE (2Mb) boundary - the allocation fails.

Description of Problem: There is a race condition if we map a same file on different processes. Region tracking is protected by mmap_sem and hugetlb_instantiation_mutex. When we do mmap, we don't grab a hugetlb_instantiation_mutex, but only mmap_sem (exclusively). This doesn't prevent other tasks from modifying the region structure, so it can be modified by two processes concurrently.
