This patch fix a concurrency issue in mremap04. The tmp directory the IPC key was build with was destroyed before we destroy the IPC ressource attached to the key. In case of concurency, the same inode id can be reused for another process tmp dir, leading to the generation of the same key. Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>.

I spent some time looking at the sched_latency test trying to see why it took so long to start the thread. The java version of the test takes a comparable amount of time to start the thread as it does for each period. The rt-test version was taking an order of magnitude longer. After digging through the java documentation, I found that the RealtimeThread does not actually start executing until the RealtimeThread.waitForNextPeriod() fulfills the time specified in the PeriodicParameters parameter included in its constructor. So all the tests are scheduled to run about 1 second after the threads are created. This gives the system plenty of time to create the thread (a non-realtime code path), set the scheduling parameters and then sleep until the specified run time. The start latency as measured by the test goes something like this:
start_time = nanoTime() + 1000000000;
rt = new realtimeThread(sched_param, new \ PeriodicParameters(start_time, ...), ..., run);
/* by the rtsj specification, this method will not run until start_time */
now = nanoTime();
start_latency = now - start_time;
The rt-tests version went something like this:
start_time = rt_gettime();
create_fifo_thread(periodic_thread, (void*)0, PRIO);
now = rt_gettime();
start_latency = now - start;
As you can see, the start_latency is a very different measurement in these two cases. In the first, it is basically the initial starting latency as measured by the remainder of the loops. In the second, the execution path of creating the pthread is also counted in the latency. While this might be an important number for us to keep low in our testing, this is not what the java test is measuring. This patch puts the rt-test version in line with the java version. I also think this is reasonable since the rt-wiki says that we should _NEVER_ create threads on the real-time stage. Signed-off-by: Vernon Mauery <firstname.lastname@example.org>.

The following patches fix execve05 for error reporting when execve() succeeds, and exit synchronization in loaded systems. The last two patches are minor cleanups. execve05 checks that execve() fails if a process has opened the file with write access. However, in case the test fails and execve() succeeds, the default binary (test3) has return code 0, which is interpreted as test success. We get output like that:
with return code 0 (success)
execve05 1 FAIL : Failures reported above
with return code matching FAIL.
This patch simply changes the success return code from 0 to 3, so that execve() success, and thus test failure, can be properly reported. Signed-off-by: Louis Rilling <Louis.Rilling@kerlabs.com>.
6) Log Message:
The following patches fix execve05 for error reporting when execve() succeeds, and exit synchronization in loaded systems. The last two patches are minor cleanups. In execve05, the first child must keep a file open at least until the second child tries to execve() this file. However the test achieves this with a sleep of 10s, which may fail on loaded systems. This patch replaces this (arbitrary) sleep with a pipe-based synchronization, where the parent notifies the first child once the second child has terminated.

7) Log Message:
The following patches fix execve05 for error reporting when execve() succeeds, and exit synchronization in loaded systems. The last two patches are minor cleanups.

9) Log Message:
This patch fix an issue in the sync_pipe implementation. The problem is the following : after the creation of a pipe we do not close any file descriptor until the end of a test. Let's imagine the following execution :
- Process A calls sync_pipe_create
- Process A do a fork (creation of process B)
- Process A calls sync_pipe_wait
---> Process A blocks on sync_pipe_wait
- Process B starts
- Process B exits because of an early error.
In this case, process A never exits. Since it has not closed its write descriptor to the pipe, the pipe is not considered as broken, thus process A is not notified its son is dead. Thus it will wait forever. Renaud Lottiaux <Renaud.Lottiaux@kerlabs.com>.

utimensat() syscall was introduced from linux-2.6.22 onwards. Michael wrote the initial testcases, and, the same is being contributed to LTP under GPLv2. I worked out a patch for this. Though this is not using LTP specific libraries at the moment. But the tests run well and tests 99 separate variations. Michael has written it through itś length and breadth. I generated the code coverage (9.2%) over 2.6.25-gcov kernel, which however was not built with <make allmodconfig> option. Please see it attached along with a draft man page of utimensat(), created by Michael. Let us know how do you feel about this test. We can then go ahead and add this to LTP.
