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

SIG

POSIX cases status platforms error msg analysis bugzilla
sigaction/16-1 Ignore qemu-mips routerstation "test not present" NO SIGSTKFLT on mips platform. Signals are defined in /usr/include/bits/signum.h n/a

sem_init/7-1 ignore qemu-arm beagleboard qemu-mips routerstation qemu-ppc mpc8315e can't test: There is no constraint on SEM_NSEMS_MAX _SC_SEM_NSEMS_MAX is not supported by sysconf(). In implement it check whether SEM_NSEMS_MAX is defined, then if defined return SEM_NSEMS_MAX, otherwise return -1. No SEM_NSEMS_MAX defined in Yocto Ubuntu and Fedora n/a

pthread_cond_broadcast/1-2 Bug qemu-arm beagleboard HUNG - "timeout" die lock issue n/a
pthread_create/1-6 POSIX qemu-arm beagleboard qemu-mips routerstation qemu-ppc mpc8315e testcase create NCPU=4 threads running with a high priority with the same sched policy policy and one with a low-priority. The low-priority thread should not run until the other threads stop running, unless the machine has more than NCPU processors. Redefine NCPU = sysconf(_SC_NPROCESSORS_CONF), testcase should pass n/a
pthread_create/10-1 POSIX qemu-arm beagleboard qemu-mips routerstation Segmentation fault test case use an uninitialized attributes object to case pthread_create() segmentation fault then catch the signal. But the uninitialized object is NOT invalid to pthread_create() all the time n/a

pthread_mutex_lock/3-1 POSIX (send patch) qemu-arm beagleboard routerstation qemu-ppc mpc8315e User defined signal 2 Signals are sended before install signal handler n/a
pthread_rwlock_rdlock/2-1 Ignore(unsupport) qemu-arm beagleboard qemu-mips routerstation qemu-ppc mpc8315e Main thread read lock 'rwlock' with high priority. 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 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. See pthread_rwlock_rdlock/2-1
pthread_rwlock_unlock/3-1 Ignore(unsupport) qemu-arm beagleboard qemu-mips routerstation qemu-ppc mpc8315e Main thread write lock 'rwlock' with high priority. Child thread1 write lock 'wrlock' with medium priority will block. Child thread2 read lock 'wrlock' with same mediumpriority. Child thread3 write lock 'wrlock' with low priority. 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'. See pthread_rwlock_rdlock/2-1

timer_getoverrun/3-1 POSIX qemu-arm beagleboard qemu-mips routerstation qemu-ppc mpc8315e Just print something and then return UNTESTED Bug 1827
timer_getoverrun/2-3 Ignore on ARM qemu-arm beagleboard routerstation "WR: Change CONFIG_HZ from 100 to 250 can solve this." The root cause is that these platform don't provide HIGH RESOLUTION TIMER. The value on platforms which test case can pass is only 1 nanosecond. But on qemuarm is 10000000 nanoseconds, on routerstation is 4000250 nanoseconds. After set CONFIG_HIGH_RES_TIMER=y for routerstation (CONFIG_HZ=250 has been set), test case passes. These 2 kernel configurations for qemuarm are not permitted. n/a
clock_getcpuclockid/5-1 Ignore qemu-arm beagleboard qemu-mips routerstation qemu-ppc mpc8315e clock_getcpuclockid(1, ..) passed unexpectedly Permission issue. When call clock_getcpuclockid() as a unpriviledge user to get process 'init' cpu time, it succeeds but expect fails with EPERM. This is not supported by Linux. In man page, it addresses EPERM " does not occur on Linux unless the kernel does not support obtaining the per-process CPU-time clock of another process.". clock_getcpuclockid() is implemented in eglibc source file libc/sysdeps/unix/sysv/linux/clock_getcpuclockid.c, call system call clock_getres() without permission check n/a

Modification of the partial page at the end of an object is written out

Test case map a file with size of 1/2 * page_size, then write char 'b' to next byte of 1/2 * page_size. 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. When do the 2nd or 3rd mmap() still get the same mapped page. n/a
