    Certification Program The Open Brand certification program
    Test Suite VSU version 5.3.3
    Test Identification CAPI.os/devclass/ptsname/T.ptsname 3
    Specification Base Definitions Issue 6
    Location in Spec http://pubs.opengroup.org/onlinepubs/9699919799/functions/rename.html
    Problem Summary ENOSYS is not being accounted for when rename() returns with an error
    on a pseudo-filesystem.
    Problem Text From tset/CAPI.os/devclass/ptsname/ptsname3.c:

    171 if(rename(before, after) == -1) {
    172 /*
    173 * If the device is on a read-only filesystem, we can't
    174 * rename it. Systems that use a pseudo-filesystem
    <<<<<--- note the comment
    175 * for slave ptys might also return other errors - here
    176 * we allow EBUSY and EPERM.
    177 */
    178 if (errno == EROFS || errno == EBUSY || errno == EPERM) {
    179 sprintf(ebuf,"INFO: rename() failed: %s",
    180 err_lookup(errno));
    181 tet_infoline(ebuf);
    182 tet_result(TET_UNTESTED);
    183 return;
    184 }
    185 uwerrno("rename"); <<<<---- enters here
    186 return;
    187 }

    From vsx/SRC/common/capi_com/misc.c:

    103 uwerrno(char *funcname)
    104 {
    105 sprintf(ebuf, "ERROR: %s failed, errno = %s", funcname,
    err_lookup(errno));
    106 tet_infoline(ebuf);
    107 tet_result(TET_UNRESOLVED); <<<---- test labeled unresolved.
    108 }


    Executing rename() on our pseudo-filesystem returns ENOSYS and based on
    the comment in the code it appears its expected to see other errno
    values slip through and are not checked. If ENOSYS was added to the if
    condition on line #178 of tset/CAPI.os/devclass/ptsname/ptsname3.c the
    test would return UNTESTED instead of UNRESOLVED.

    errno.h 155 #define ENOSYS 89 /* Unsupported file system
    operation */
    Test Output **********************************************************************
    /tset/CAPI.os/devclass/ptsname/T.ptsname 3 Unresolved

    Test Description:
    Base Required Deviance
    A call to char *ptsname(int fildes) when the slave device name does
    not exist in the file system shall return NULL.

    Test Information:
    PREP: Open master pseudo terminal
    PREP: Get slave pseudo terminal
    PREP: Unlock slave device
    PREP: Get name of pseudo terminal device
    PREP: Rename /dev/pts/3 to /dev/pts/3.save
    ERROR: rename failed, errno = 89 (ENOSYS - Function not supported)
