POSIX-results
Introduction
This page records the POSIX test results of Yocto for current version. History POSIX test results have been moved to https://wiki.yoctoproject.org/wiki/POSIX_History_Results. You can get more informations from POSIX test overall on Yocto.
The online POSIX specification could be viewed at IEEE Std 1003.1, 2004 Edition.
The POSIX test suite is from ltp and current version is 20120903. All POSIX test cases can be get at POSIX git repository.
Test POSIX on following platforms:
- beagleboard
- mpc8315rdb
- routerstation
- sugarbay
- blacksand
- huronriver
There are 1794 test cases in total, only failed items are list here.
Result Codes
These informations are from POSIX test suit Documentation/HOWTO_ResultCodes.
The PTS result codes are:
#define PTS_PASS 0 #define PTS_FAIL 1 #define PTS_UNRESOLVED 2 #define PTS_UNSUPPORTED 4 #define PTS_UNTESTED 5
A brief discussion of each of these follows:
PTP_PASS Used when the test executes fully with no problems and passes.
PTP_FAIL Used when the test executes fully, but fails.
PTP_UNRESOLVED Used when the test was blocked from fully completing and
the pass/failure results cannot be determined.
PTP_UNSUPPORTED Used if the test is for a conditional feature that is
not implemented.
PTP_UNTESTED Used when a feature does not have a test associated
with it because:
- The test is just a stub and doesn't do anything
- The test is only partially complete and can't really
finish the test
- The test is complete in some cases, but certain things
can happen that leave the test incomplete. When these
happen, it's PTP_UNTESTED.
For every failed case which returns PTP_FAIL there is a item in https://bugzilla.yoctoproject.org to follow. For other cases which don't return PTP_PASS find the root cause.
Results and analysis
The results of groups SIG SEM THR TMR MSG TPS MEM are listed. Conclusion of some test cases have been given.
Values of clumn "status" descript the current status of the case. Some keywords include:
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
Version
Current result is for Yocto 1.3M3 RC2 20120814 build with POSIX test suite version 20120614.

conformance/interfaces/lio_listio/11-1: execution: FAILED lio_listio/11-1.c Error lio_listio() should have returned -1 |
for aio_lio_opcode posix says "The supported operations are LIO_READ, LIO_WRITE, and LIO_NOP" but it does not say what should happen if the value it not one of the above. eglibc doesn't validate the parameter aio_lio_opcode when in function __aio_enqueue_request called by lio_listio() |
Yocto 2660 |
| aio_return/2-1 | Not A Bug | sugarbay blacksand huronriver mpc8315e routerstation beagleboard | conformance/interfaces/aio_return/2-1: execution: UNRESOLVED
aio_return/2-1.c Second call to aio_return() may return -1; aio_return() returned 111 |
In specification, second call to aio_return() return -1 is a kind of possibility, depends on implementation. In eglibc the return value is same as first return. |

In eglibc, sysconf() is implemented in sysdeps/posix/sysconf.c. When pass _SC_SEM_NSEMS_MAX to sysconf(), it checks whether SEM_NSEMS_MAX is defined, then if defined return SEM_NSEMS_MAX, otherwise return -1.
No SEM_NSEMS_MAX defined in Yocto same as in Ubuntu and Fedora, so the case fails. It return UNTESTED(Result Codes), we don't need care it. |

But eglibc/libc don't support this option. They provide a rwlock->__data.__flags option to identify perfer 'read lock' or write lock, and the default is 'read lock' first. So second reader can get the lock when a higher priority writer is waiting for the lock.

pa: 0x400fb000 pa_2: 0x40115000 Modification of the partial page at the end of an object is written out |
This case maps a file with length 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 root cause is that 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. This case is not supported by Linux. 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(). When access the Virtual Memory Area, page fault will occur and the run filemap_fault(). In filemap_fault(), kernel run find_get_page() to search the physical page in the page cache. |

Modification of the partial page at the end of an object is written out |
Same with mmap/11-4, and this case test share memory instead of regular file.
shmfs's file->f_op->mmap() point to shm_fault() in ipc/shm.c, then it call shmem_fault() ==> shmem_getpage() ==> shmem_getpage_gfp() ==> find_lock_page(). In find_lock_page() it will search the desired pagecache page. |

Test Fail: mmap/28-1.c Got no error at mmap() |
This case tests mmap() with length of 2 timed file size and expects fail with errno ENXIO( No such device or address), but mmap() successed.
Because Linux kernel just make the mmap connection between file and memory when mmap() called. When first read/write, the kernel mmap the physical file page to the virtual memory page. So it doesn't fail in mmap(). This case is NOT supported by Linux. |

off: fffff000, len: fffff000 expect EOVERFLOW but get other error: Cannot allocate memory |
Parameters lenth and offset for mmap() are too large. Case 24-2 with same length expects mmap() failed with ENOMEM.
In function get_unmapped_area(), it checks len should less than TASK_SIZE, otherwise it returns -ENOMEM. TASK_SIZE value on different platforms beagleboard 0xC0000000 - 0x01000000 = 0xBF000000 mpc8315e 0xc0000000 routerstation 0x7fff8000UL sugarbay 0xffff880000000000 |
