POSIX-results

Introduction

This page records the POSIX test results of Yocto 1.2. You can get more informations from POSIX test overall on Yocto. The test suite is from ltp and version 20110915. Six platforms are included: qemu-arm qemu-ppc qemu-mips beagleboard mpc8315rdb routerstation. There are 1794 test cases in total, only failed items are list here.

All POSIX test cases can be get at POSIX git repository.

The online POSIX specification could be viewed at IEEE Std 1003.1, 2004 Edition.

Results and analysis

The results of groups SIG SEM THR TMR MSG TPS MEM are listed. Conclusion of some test cases have been given.

Value of clumn "status":

Bug: it is a bug and the test case needs to be fixed.

Ignore: the case is not appropriate for the hardware or linux

POSIX: that test case is in development, that causes the test fails

Child thread1 write lock 'wrlock' with medium priority will block. child thread2 read lock 'rwlock' with low priority should block because a high priority write lock is waiting, but read lock doesn't block.	This test case is to test option Thread Execution Scheduling of pthread rwlock. But eglibc/libc don't support this option. They provide a __flags option to identify perfer 'read lock' or read lock, and the default is 'read lock' first. A Non-portable api pthread_rwlockattr_setkind_np() is provided to set this value. The test case is not supported.
pthread_rwlock_rdlock/2-2	Ignore(unsupport)	qemu-arm beagleboard qemu-mips routerstation qemu-ppc mpc8315e sugarbay blacksand	Main thread read lock 'rwlock' with high priority. Child thread1 write lock 'wrlock' with low priority will block. child thread2 read lock 'rwlock' with same low priority should block because a same priority write lock is waiting, but read lock doesn't block.

When main thread unlock 'rwlock', child thread1 get the 'wrlock'. When child thread1 unlock 'rwlock', child thread2 should get the read lock 'wrlock' because it has higher priority than child thread3. But it is the child thread3 who get the 'wrlock'.

sched_getparam/6-1	Ignore	qemu-arm beagleboard qemu-mips routerstation qemu-ppc mpc8315e sugarbay blacksand		sched_getparam is a system call, and defined in kernel/sched.c:L5510.

Its task_getscheduler() refer to cap_task_getscheduler() and doesn't perform any permission check. WR: A permission test. On Linux, the kernel makes no check on user permission to call this API.

Then try to re-mmap() the file and expect the byte next to of 1/2 * page_size should not be character 'b'. Test on all platforms are failed. The reason is after first mmap(), the mapped page for the file is cached in page cache. When do the 2nd or 3rd mmap() still get the same mapped page. The mapped page is cached. mmap() is a system call and implemented by mmap2(). Then the call sequence is mmap2() ==> sys_mmap_pgoff() ==> do_mmap_pgoff() ==> mmap_region() ==> file->f_op->mmap(). In ext3 file system, file->f_op->mmap() point to generic_file_mmap(). In generic_file_mmap(), assign the Page Fault Exception Handler to filemap_fault().
