  6. ba2cfc0 mem/hugetlb: fix failure of hugemmap03: 1) In mmap's manual, The starting address for the new mapping is specified in addr. So, if mmap's argument "addr" is reachable, the mmap will creates a new mapping in the virtual address space of the call-ing process. The test hugemmap03 will test that a normal page cannot be mapped into a high memory region. This infers that "addr" should be higher for 64-bit mode. 2) The test use "-I2" option, and this not only causes TFAIL's loop, but also causes TPASS's loop. For TFAIL, loop is deserved, nor for TPASS. This patch fixed these problems. Signed-off-by: Liu Bo <liubo2009@cn.fujitsu.com>. by subrata_modak · 15 years ago

  15. 88c166c Test library cleanups: Removing no longer used code from test.h eg. test_error.c is no longer in ltp, and the same for t_res.c so there is no need to include function prototypes for these. Adding void to functions that doesn't take any parameters; tst_exit() -> tst_exit(void); so code that pases parameters to these is not compileable any more. Also fixes all test broken by that change. As parameters passed to tst_exit() are ignored anyway it's quite safe to just remove them; but I'would rather see someone take a closer look.

  21. 9650284 RFC: Fixes for Shared Memory test case shmat: Shmat1.c(testcases/kernel/mem/mtest06) is a test case which tries to create 3 threads during its execution. One thread allocates shared memory, second writes to the shared memory and the third reads from the shared memory. All the 3 threads are synchronized using a global variable. In case of signal (sigsegv) sighandler will be called. The current test case implementation is complete only for x86 arc and is not valid for other archs. We have noticed various issues while executing this test case. Test case issues can be summarized as: by subrata_modak · 16 years ago

Now, i leave it on the discrition of the user to increase the hugepages in their system before executing these tests. Else, if you all agree on some way to autoset that before test execution, it would be welcome. Following patches Follow: by subrata_modak · 16 years ago

  46. b6ecbe3 I've attached some patches that I created for LTP at work. Most of them simply add command-line options to specify the amount of memory/pages to use for tests. However, there's one fix that works around a bug in uClibc's pthread implementation. Allow the number of pages to use for the test to be specified on the command-line. Fix a memory leak. Also, call _exit(2) from child processes which avoids the child calling the atexit functions that the pthread library setup. This fixes an issue where the pthread manager thread would begin exiting at the same time as a child thread. The child thread would run the atexit functions which cause it to wait for a signal to be sent from the thread manager. As the thread manager was trying to exit that signal would never be sent. Calling _exit(2) from the child avoids this whole mess.Matt Fleming <mjf@gentoo.org>. by subrata_modak · 16 years ago

  49. 0417704 mallocstress stresses the VMM and C library by spawning N threads which malloc blocks of increasing size until malloc returns NULL.

  51. 3b8e06c I see Roy's patch was already checked in. In principle I agree with the patch, but a few things are wrong now and IMHO does not fulfill what it should test any longer. shm05.c -> see my (untested!!!) patch below. Some architectures can only map at specific offsets. Current version "sucessfully" fails, because e.g. hppa can't map at cp+4096. So, it's not failing because the memory regions overlap, although that was intended to be tested...shm06.c now does basically the same test as shm04.c ?!? Doesn't make sense... I would revert the patch for shm06, but maybe others think different???? Other patches seem ok, although I haven't looked too deep into them yet...

  52. 78b1912 This patch modifies testcases to attach their shm segment to addresses chosen by ststem instead of arch-dependent ones. I looked into the history of these testcases, but couldn't find the reason why they specified arch-dependent addresses in the first place. If it has something to do with the page coloring issue, SHMLBA should be in some manners instead of defining arch-dependent addresses.

  55. 8f89991 It seems that hugeshmctl01 doesn't free some hugetlb pages when it fails. ps shows that there is still an instance of hugeshmctl01 left even if hugeshmctl01 is not running which may attach some hugetlb pages. The problem is due to the arbitrary usleep time in hugeshmctl01 which results in incorrect execution order. The intention of the sleep time is to ensure the children call shmat() and pause() before the parent checks shm status and calls stat_cleanup(). But there is no absolute assurance that this sleep always works. In the failure above, the last child process forked by the parent may not run and call shmat() immediately after it's created. When the parent checks shm status, it finds only 3 child attaching the shm instead of 4, so it reports the failure. And then it calls stat_cleanup() to send SIGUSR1 to all children, but since the last child hasn't called pause() yet, SIGUSR1 is handled before pause(). When the last child calls pause(), since there is no further signal to wake it up, it sleeps forever. patch to ensure children can receive and handle SIGUSR1 from parent in pause(). The patch is not to change the arbitrary usleep time since any time is arbitrary though a large time is more acceptable. The patch is to use sigprocmask() to block SIGUSR1 before children sleep for SIGUSR1 from parent, and then call sigsuspend() to unblock SIGUSR1 and sleep for SIGUSR1. By doing so, we may avoid the infinite sleep and keeping attached shm forever so that affect other hugetlb test. In parent process, aonther sigprocmask() is called before usleep(). This has the same effect of sleep more time. By, shenlinf <shenlinf@cn.ibm.com> by subrata_modak · 17 years ago
