[PATCH] compat_sys_fcntl[64] contain superfluous, buggy test · 2761f394

Andreas Gruenbacher authored Nov 19, 2004

here is a fix to a previous ChangeSet from John; 32-bit emulation of flock(fd,
F_GETLK, &lock) currently is broken.

The ChangeSet:
http://linux.bkbits.net:8080/linux-2.5/cset%404152257aJKu1UClRcfvhsK6IjGYSeQ?nav=index.html|ChangeSet@-12w
from John Engel <jhe@us.ibm.com> fixes an off-by-one error and according
to the ChangeSet comment, it also contains a fix to handle l_len < 0 which
is now defined in POSIX 1003.1-2001 from the fcntl man page.

Gordon Jin <gordon.jin@intel.com> reports that the added test causes
compat_sys_fcntl[64] to fail: If fcntl(fd, F_GETLK, &lock) finds no
conflicting lock it sets l_whence to F_UNLCK, leaves all the other fields
unchanged, and returns 0.  The (f.l_start < 0) test wrongly converts this
to an EINVAL result.

The underlying sys_fcntl function which compat_sys_fcntl and
compat_sys_fcntl64 invoke already handles POSIX behavior correctly.  The
additional tests in the compat wrappers are not needed.

Here is a test case; its expected result is:

PASS

[PATCH] (4/4) eicon iomem annotations and fixes · 42f61295

Alexander Viro authored Nov 19, 2004

 * s_4bri.c has a nasty typo - bogus & in qBri_cpu_trapped().

   We have
	void *base;
   followed by
	regs[0] = READ_DWORD((&base + offset) + 0x70);

   which is *NOT* what is meant there - instead of access to memory
   pointed to by base we get access to _stack_ at some offset from the
   place where the local variable base lives.

Alexander Viro authored Nov 19, 2004

 * new helpers - READ_BYTE() and WRITE_BYTE().  On Linux they are
   needed, since direct access to iomem pointers is not allowed (and
   does not work on some architectures).
 * memcpy() to/from iomem is not allowed on Linux (same story).

Proper primitives are memcpy_toio() and memcpy_fromio().  Several places
misused memcpy(); switched to memcpy_{to,from}io().

These routine in arm is unused (in fact not even compiled).

Instead of converting it to local_softirq_pending I'd suggest just
removing it as below as it's been there totally unused for a long
