14 years ago[PATCH] autofs4: can't mount due to mount point dir not empty

[PATCH] autofs4: can't mount due to mount point dir not empty

Addresse a problem where stale dentrys stop mounts from happening.

When a mount point directory is pre-created and a non-existent entry within it
is requested a dentry ends up being created within the mount point directory
which stops future mounts.  The problem is solved by ignoring negative,
unhashed dentrys in the mount point d_subdirs list.

Additionally the apparent cacheing of -ENOENT returns from requests is
removed.  The test on d_time is a tautology and d_time is not initialised and
has an unexpected value.  In short it doesn't do what it's meant to.

The cacheing of failed requests to the daemon is important and will be
followed up later.

Change readdir routines to use the cursor based routines in libfs.c.  This

ran immediately, it would see the uninitialized data, including an empty

paths and cleanup accordingly.

Jeff Dike [Mon, 27 Mar 2006 09:14:38 +0000]
[PATCH] uml: fix segfault on signal delivery

This fixes a process segfault where a signal was being delivered such that a
new stack page needed to be allocated to hold the signal frame.  This was
tripping some logic in the page fault handler which wouldn't allocate the page
if the faulting address was more that 32 bytes lower than the current stack
pointer.  Since a signal frame is greater than 32 bytes, this exercised that
case.

It's fixed by updating the SP in the pt_regs before starting to copy the
signal frame.  Since those are the registers that will be copied on to the
stack, we have to be careful to put the original SP, not the new one which
points to the signal frame, on the stack.

[PATCH] uml: more carefully test whether we are in a system call

For security reasons, UML in is_syscall() needs to have access to code in
vsyscall-page.  The current implementation grants this access by explicitly
allowing access to vsyscall in access_ok_skas().  With this change,
copy_from_user() may be used to read the code.  Ptrace access to vsyscall-page
for debugging already was implemented in get_user_pages() by mainline.  In
i386, copy_from_user can't access vsyscall-page, but returns EFAULT.

To make UML behave as i386 does, I changed is_syscall to use
access_process_vm(current) to read the code from vsyscall-page.  This doesn't
hurt security, but simplifies the code and prepares implementation of
stub-vmas.

[PATCH] PM-Timer: don't use workaround if chipset is not buggy

Current timer_pm.c reads I/O port triple times, in order to avoid the bug
of chipset.  But I/O port is slow.

2.6.16 (pmtmr)
Simple gettimeofday: 3.6532 microseconds

2.6.16+patch (pmtmr)
Simple gettimeofday: 1.4582 microseconds

[if chip is buggy, probably it will be 7us or more in 4.2% of probability.]

This patch adds blacklist of buggy chip, and if chip is not buggy, this
uses fast normal version instead of slow workaround version.

If chip is buggy, warnings "pmtmr is slow".  But sounds like there is gray
zone.  I found the PIIX4 errata, but I couldn't find the ICH4 errata.  But
some motherboard seems to have problem.

So, if we found a ICH4, generate warnings, and use a workaround version.
If user's ICH4 is good, the user can specify the "pmtmr_good" boot
parameter to use fast version.

Akinobu Mita [Sun, 26 Mar 2006 09:40:00 +0000]
[PATCH] bitops: hweight() speedup

<linux@horizon.com> wrote:

This is an extremely well-known technique.  You can see a similar version that
uses a multiply for the last few steps at
http://graphics.stanford.edu/~seander/bithacks.html#CountBitsSetParallel whch
refers to "Software Optimization Guide for AMD Athlon 64 and Opteron
Processors"
http://www.amd.com/us-en/assets/content_type/white_papers_and_tech_docs/25112.PDF

It's section 8.6, "Efficient Implementation of Population-Count Function in
32-bit Mode", pages 179-180.

It uses the name that I am more familiar with, "popcount" (population count),
although "Hamming weight" also makes sense.

Anyway, the proof of correctness proceeds as follows:

b = a - ((a >> 1) & 0x55555555);
c = (b & 0x33333333) + ((b >> 2) & 0x33333333);
d = (c + (c >> 4)) & 0x0f0f0f0f;
#if SLOW_MULTIPLY
e = d + (d >> 8)
f = e + (e >> 16);
return f & 63;
#else
/* Useful if multiply takes at most 4 cycles */
return (d * 0x01010101) >> 24;
#endif

The input value a can be thought of as 32 1-bit fields each holding their own
hamming weight.  Now look at it as 16 2-bit fields.  Each 2-bit field a1..a0
has the value 2*a1 + a0.  This can be converted into the hamming weight of the
2-bit field a1+a0 by subtracting a1.

That's what the (a >> 1) & mask subtraction does.  Since there can be no
borrows, you can just do it all at once.

Enumerating the 4 possible cases:

0b00 = 0  ->  0 - 0 = 0
0b01 = 1  ->  1 - 0 = 1
0b10 = 2  ->  2 - 1 = 1
0b11 = 3  ->  3 - 1 = 2

The next step consists of breaking up b (made of 16 2-bir fields) into
even and odd halves and adding them into 4-bit fields.  Since the largest
possible sum is 2+2 = 4, which will not fit into a 4-bit field, the 2-bit
                           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
                          "which will not fit into a 2-bit field"

fields have to be masked before they are added.

After this point, the masking can be delayed.  Each 4-bit field holds a
population count from 0..4, taking at most 3 bits.  These numbers can be added
without overflowing a 4-bit field, so we can compute c + (c >> 4), and only
then mask off the unwanted bits.

This produces d, a number of 4 8-bit fields, each in the range 0..8.  From
this point, we can shift and add d multiple times without overflowing an 8-bit
field, and only do a final mask at the end.

The number to mask with has to be at least 63 (so that 32 on't be truncated),
but can also be 128 or 255.  The x86 has a special encoding for signed
immediate byte values -128..127, so the value of 255 is slower.  On other
processors, a special "sign extend byte" instruction might be faster.

On a processor with fast integer multiplies (Athlon but not P4), you can
reduce the final few serially dependent instructions to a single integer
multiply.  Consider d to be 3 8-bit values d3, d2, d1 and d0, each in the
range 0..8.  The multiply forms the partial products:

           d3 d2 d1 d0
        d3 d2 d1 d0
     d3 d2 d1 d0
+ d3 d2 d1 d0
----------------------
           e3 e2 e1 e0

Where e3 = d3 + d2 + d1 + d0.   e2, e1 and e0 obviously cannot generate
any carries.

- hweight64() will be defined on all architectures
- hweight_long() will use architecture optimized hweight32() or hweight64()

I found two possible cleanups by these reasons.

[PATCH] bitops: remove unused generic bitops in include/linux/bitops.h

generic_{ffs,fls,fls64,hweight{64,32,16,8}}() were moved into
include/asm-generic/bitops.h.  So all architectures don't use them.

[PATCH] bitops: ntfs: remove generic_ffs()

Now the only user who are using generic_ffs() is ntfs filesystem.  This patch
isolates generic_ffs() as ntfs_ffs() for ntfs.

[PATCH] bitops: ia64: make partial_page.bitmap an unsigned long

The find_*_bit() routines are defined to work on a pointer to unsigned long.
But partial_page.bitmap is unsigned int and it is passed to find_*_bit() in
arch/ia64/ia32/sys_ia32.c.  So the compiler will print warnings.

This patch changes to unsigned long instead.

The test_bit() routines are defined to work on a pointer to unsigned long.
But thread_info.flags is __u32 (unsigned int) on sh and it is passed to flag

[PATCH] bitops: use non atomic operations for minix_*_bit() and ext2_*_bit()

Bitmap functions for the minix filesystem and the ext2 filesystem except
ext2_set_bit_atomic() and ext2_clear_bit_atomic() do not require the atomic
guarantees.

But these are defined by using atomic bit operations on several architectures.
 (cris, frv, h8300, ia64, m32r, m68k, m68knommu, mips, s390, sh, sh64, sparc,
sparc64, v850, and xtensa)

This patch switches to non atomic bit operation.

Dave Peterson [Sun, 26 Mar 2006 09:38:49 +0000]
[PATCH] EDAC: kobject/sysfs fixes

- After we unregister a kobject, wait for our kobject release method
  to call complete().  This causes us to wait until the kobject
  reference count reaches 0.  Otherwise, a task accessing the EDAC
  sysfs interface can hold the reference count above 0 until after the
  EDAC module has been unloaded.  When the reference count finally
  drops to 0, this will result in an attempt to call our release
  method inside the EDAC module after the module has already been
  unloaded.

  This isn't the best fix, since a process can get stuck sleeping forever
  uninterruptibly if the user does the following:

      rmmod my_module < /sys/my_sysfs/file

  I'll go back and implement a better fix later.  However this should
  be ok for now.

- Call edac_remove_sysfs_mci_device() from edac_mc_del_mc() rather
  than from edac_mc_free().  Since edac_mc_add_mc() calls
  edac_create_sysfs_mci_device(), edac_mc_del_mc() should call
  edac_remove_sysfs_mci_device().

Dave Peterson [Sun, 26 Mar 2006 09:38:48 +0000]
[PATCH] EDAC: kobject_init/kobject_put fixes

- Remove calls to kobject_init().  These are unnecessary because
  kobject_register() calls kobject_init().

- Remove extra calls to kobject_put().  When we call
  kobject_unregister(), this releases our reference to the kobject.
  The extra calls to kobject_put() may cause the reference count to
  drop to 0 while a kobject is still in use.

[PATCH] EDAC: edac_mc_add_mc fix [1/2]

This is part 1 of a 2-part patch set.  The code changes are split into
two parts to make the patches more readable.

Move complete_mc_list_del() and del_mc_from_global_list() so we can
call del_mc_from_global_list() from edac_mc_add_mc() without forward
declarations.  Perhaps using forward declarations would be better?
I'm doing things this way because the rest of the code is missing
them.

[PATCH] EDAC: cleanup code for clearing initial errors

Fix xxx_probe1() functions so they call xxx_get_error_info() functions
to clear initial errors.  This is simpler and cleaner than duplicating
the low-level code for accessing PCI config space.
