| Problem Summary |
prototype of tb_mmap() not defined as fully qualified in
vsx0/tset/rt.os/mfiles/mmap_P/mmap_P.c causes test failure |
|---|
| Problem Text |
In vsx0/tset/rt.os/mfiles/mmap_P/mmap_P.c
The declaration of tb_mmap:
private int *tb_mmap();
The implementation:
private void * tb_mmap(addr, len, prot, flags, fildes, off)
void *addr;
size_t len;
int prot;
int flags;
int fildes;
off_t off;
{ ... }
This cause the following cases failed;
/tset/rt.os/mfiles/mmap_P/T.mmap_P 13 Failed
/tset/rt.os/mfiles/mmap_P/T.mmap_P 23 Failed
When the tb_mmap called in the /tset/rt.os/mfiles/mmap_P/T.mmap_P
13:
/Map in a whole page/
if ((addr = (int
*)tb_mmap(0,vsrt_pgsz,PROT_READ|PROT_WRITE,MAP_SHARED,fd1,0)) ==
(int *)MAP_FAILED) {
err = errno;
xx_rpt(FAILURE);
in_rpt("mmap failed, errno = %d (%s)", err, errname(err));
(void)close(fd1);
(void)unlink(test_file);
DBUG_VOID_RETURN
} else
PATH_TRACE;
The value of the last parameter off is 0. But when it pass into the
tb_mmap , it changes to be anothre vaule. This change cause the
error returned form mmap, error code is errno = 22 (EINVAL) |

| Test Output |
/tset/rt.os/mfiles/mmap_P/T.mmap_P 13 Failed
Test Description:
If _POSIX_MAPPED_FILES is defined or the implementation supports the
mmap() function:
The system shall not write out modified portions of the last page of a
file mapped by a call to mmap() which are beyond the end of the file.
Test Information:
mmap failed, errno = 22 (EINVAL)
/tset/rt.os/mfiles/mmap_P/T.mmap_P 23 Failed
Test Description:
If _POSIX_MAPPED_FILES is defined or the implementation supports the
mmap() function:
The mapping established by a call to mmap() shall replace any
previous mappings for those whole pages containing any part of the
address space of the process starting at pa and continuing for len
bytes.
Test Information:
mmap failed, errno = 22 (EINVAL) |
