Even after the previous fix you can still set CONFIG_ACPI_BOOT
indirectly even without CONFIG_ACPI by choosing CONFIG_PCI and
CONFIG_PCI_MMCONFIG.

That doesn't build very well either.

This makes PCI_MMCONFIG depend on ACPI, fixing that hole.

[ I guess in theory Kconfig could follow the whole chain of dependencies
  for things that get selected, but that sounds insanely complicated, so
  we'll just fix up these things by hand.  --Linus ]

15 years ago[PATCH] cpuset exit NULL dereference fix
Paul Jackson [Fri, 27 May 2005 09:02:43 +0000]
[PATCH] cpuset exit NULL dereference fix

There is a race in the kernel cpuset code, between the code
to handle notify_on_release, and the code to remove a cpuset.
The notify_on_release code can end up trying to access a
cpuset that has been removed.  In the most common case, this
causes a NULL pointer dereference from the routine cpuset_path.
However all manner of bad things are possible, in theory at least.

The existing code decrements the cpuset use count, and if the
count goes to zero, processes the notify_on_release request,
if appropriate.  However, once the count goes to zero, unless we
are holding the global cpuset_sem semaphore, there is nothing to
stop another task from immediately removing the cpuset entirely,
and recycling its memory.

The obvious fix would be to always hold the cpuset_sem
semaphore while decrementing the use count and dealing with
notify_on_release.  However we don't want to force a global
semaphore into the mainline task exit path, as that might create
a scaling problem.

The actual fix is almost as easy - since this is only an issue
for cpusets using notify_on_release, which the top level big
cpusets don't normally need to use, only take the cpuset_sem
for cpusets using notify_on_release.

This code has been run for hours without a hiccup, while running
a cpuset create/destroy stress test that could crash the existing
kernel in seconds.  This patch applies to the current -linus
git kernel.

15 years ago[PATCH] remove non-cleanroom pwc driver compression
Alan Cox [Fri, 27 May 2005 12:40:53 +0000]
[PATCH] remove non-cleanroom pwc driver compression

The original pwc author raised some questions about the reverse
engineering of the decompressor algorithms used in the pwc driver.
Having done some detailed investigation it appears those concerns that
clean room policy was not followed are reasonable.  I've also had a
friendly discussion with Philips to ask their view on this.

This removes the problem items of code which reduces the pwc
functionality in the kernel a little but leaves all the framework for
setup that will be needed for decompressors in user space (where they
eventually belong).  This change set is designed to be the minimal risk
change set given that 2.6.12 is hopefully close to hand, with a view to
merging the much updated pwc code in 2.6.13 series kernels.

Someone else can then redo the decompressors properly (clean room) in
user space.

Note that while its easy to say that it should have been caught earlier,
but the violation was really only obvious to someone who had access to
both the proprietary source and the 'GPL' source.

[PATCH] i386: fix prevent_tail_call

We fixed this bug before, but it didn't take.  It may have been the case
that the problem was first noticed to occur in a CONFIG_REGPARM compile.
But it's not regparm functions that need not to make tail calls, it's
asmlinkage functions called with a user pt_regs frame on the stack
supplying their arguments.  prevent_tail_call probably doesn't do anything
at all in regparm functions (your argument registers are going to be
clobbered, period).  It was a braino to conditionalize that definition in
the first place.

Stephen Hemminger [Thu, 26 May 2005 19:55:01 +0000]
[PKT_SCHED] netem: use only inner qdisc -- no private skbuff queue

Netem works better if there if packets are just queued in the inner discipline
rather than having a separate delayed queue. Change to use the dequeue/requeue
to peek like TBF does.

By doing this potential qlen problems with the old method are avoided. The problems
happened when the netem_run that moved packets from the inner discipline to the nested
discipline failed (because inner queue was full). This happened in dequeue, so the
effective qlen of the netem would be decreased (because of the drop), but there was
no way to keep the outer qdisc (caller of netem dequeue) in sync.

The problem window is still there since this patch doesn't address the issue of
requeue failing in netem_dequeue, but that shouldn't happen since the sequence dequeue/requeue
should always work.  Long term correct fix is to implement qdisc->peek in all the qdisc's
to allow for this (needed by several other qdisc's as well).

[PATCH] timeout at boottime with NEC3500A (and possibly others) when inserted a CD in it

From: Marcello Maggioni <hayarms@gmail.com>

Problem: Some drives (NEC 3500, TDK 1616N, Mad-dog MD-16XDVD9, RICOH
MP5163DA, Memorex DVD9 drive and IO-DATA's too for sure), if a
CD/DVD is inserted into the tray when the system is booted and if
before the OS bootup the BIOS checked for the presence of a bootable
CD/DVD into the drive, during the IDE probe phase the drive may
result busy and remain so for the next 25/30 seconds . This cause the
drive to be skipped during the booting phase and not begin usable
until the next reboot (if the reboot goes well and the drive doesn't
timeout again).

Solution: Rising the timeout time from 10 seconds to 35 seconds
(during these 35 seconds every drive should wake up for sure
according to the tests I've done).

Albert Lee [Thu, 26 May 2005 07:49:42 +0000]
[PATCH] libata: Fix zero sg_dma_len() on 64-bit platform

When testing ATAPI PIO data transfer on the ppc64 platform,  __atapi_pio_bytes() got zero when
sg_dma_len() is used. I checked the <asm-ppc64/scatterlish.h>, the struct scatterlist is defined as:

struct scatterlist {
struct page *page;
unsigned int offset;
unsigned int length;

/* For TCE support */
u32 dma_address;
u32 dma_length;
};

#define sg_dma_address(sg) ((sg)->dma_address)
#define sg_dma_len(sg) ((sg)->dma_length)

So, if the scatterlist is not DMA mapped, sg_dma_len() will return zero on ppc64.
The same problem should occur on the x86-64 platform.
On the i386 platform, sg_dma_len() returns sg->length, that's why the problem does not occur on an i386.

Changes:
- Use sg->length if the scatterlist is not DMA mapped (yet).

[PATCH] IB: allow NULL sa_query callbacks

Check if a client passes a NULL callback into an SA query, and if so, never
call back.  This fixes an oops if someone unloads ib_ipoib and ib_sa in
rapid succession.  ib_ipoib does an MCMember delete with a NULL callback
and 0 timeout on unload, which is usually fine since the delete completes
successfully.  However, if ib_sa is unloaded immediately afterwards, the
delete will be canceled and ib_sa will try to call the (now already
unloaded) ib_ipoib module back with the cancel completion, which triggers
the oops.

[PATCH] ppc64: fix initialisation of gettimeofday calculations

On PPC64, we keep track of when we need to update jiffies (and the
variables used to calculate the time of day) based on the time base.

If the time base frequence is sufficiently high compared to the
processor clock frequency, then it is possible for the time of day
variables to be corrupted at the time of the first decrementer interrupt
we take.  This became obvious on a legacy iSeries where the time base
frequency is the same as the processor clock.

This one line patch fixes the initialisation so that the time of day
variables and the indicator we use to tell when updates are due are
better synchronised.

However, this does hurt performance substantially, particularly with

So provide a "-P" boot option that forces the P-Cache on.  It taints
the kernel, so if it does trigger and cause some data corruption or
OOPS, we will find out in the logs that this option was on when it

time the ACK is sent and gets back to the sender, most of the window
has emptied of data and performance suffers significantly.

Debugging shows that there were some iocbs which were not getting completed
eventhough the last retry for those returned -EIOCBQUEUED.  Also all such
pending iocbs represented READ operation.

Further debugging revealed that all such iocbs hit EOF in the DIO layer.
To be more precise, the "pos" from which they were trying to read was
greater than the "size" of the file.  So the generic_file_direct_IO
returned 0.

This happens rarely as there is already a check in
__generic_file_aio_read(), for whether "pos" < "size" before calling direct
IO routine.

>size = i_size_read(inode);
>if (pos < size) {
>   retval = generic_file_direct_IO(READ, iocb,
>                               iov, pos, nr_segs);

But for READ, we are taking the inode->i_sem only in the DIO layer.  So it
is possible that some other process can change the size of the file before
we take the i_sem.  In such a case ( when "pos" > "size"), the
__generic_file_aio_read() would return -EIOCBQUEUED even though there were
no I/O requests submitted by the DIO layer.  This would cause the AIO layer
to expect aio_complete() for THE iocb, which doesnot happen.  And thus the
test hangs forever, waiting for an I/O completion, where there are no
requests submitted at all.

The following patch makes __generic_file_aio_read() return 0 (instead of
returning -EIOCBQUEUED), on getting 0 from generic_file_direct_IO(), so
that the AIO layer does the aio_complete().

Testing:

I have tested the patch on a SMP machine(with 2 Pentium 4 (HT)) running
linux-2.6.12-rc3-mm3.  I ran the ltp-aiodio testcases and none of the
fsx-linux tests hung.  Also the aio-stress tests ran without any problem.

[PATCH] reiserfs: max_key fix

This patch fixes a bug introduced by Al Viro's patch: [patch 136/174]
reiserfs endianness: clone struct reiserfs_key

The problem is MAX_KEY and MAX_IN_CORE_KEY defined in this patch do not
look equal from reiserfs comp_key's point of view.  This caused reiserfs'

Samuel Thibault [Sat, 21 May 2005 15:50:15 +0000]
[PATCH] spin_unlock_bh() and preempt_check_resched()

In _spin_unlock_bh(lock):
do { \
_raw_spin_unlock(lock); \
preempt_enable(); \
local_bh_enable(); \
__release(lock); \
} while (0)

there is no reason for using preempt_enable() instead of a simple
preempt_enable_no_resched()

Since we know bottom halves are disabled, preempt_schedule() will always
return at once (preempt_count!=0), and hence preempt_check_resched() is
useless here...

This fixes it by using "preempt_enable_no_resched()" instead of the
"preempt_enable()", and thus avoids the useless preempt_check_resched()
just before re-enabling bottom halves.

[PATCH] x86_64: Fix 32bit system call restart

The test case at
http://cvs.sourceforge.net/viewcvs.py/posixtest/posixtestsuite/conforman
ce/interfaces/clock_nanosleep/1-5.c fails if it runs as a 32bit process on
x86_86 machines.

The root cause is the sub 32bit process fails to restart the syscall after it
is interrupted by a signal.

The syscall number of sys_restart_syscall in table sys_call_table is
__NR_restart_syscall (219) while it's __NR_ia32_restart_syscall
(0) in ia32_sys_call_table. When regs->rax==(unsigned
long)-ERESTART_RESTARTBLOCK, function do_signal doesn't distinguish if
the process is 64bit or 32bit, and always sets restart syscall number
as __NR_restart_syscall (219).
