[PATCH] try_to_unmap_cluster() passes out-of-bounds pte to pte_unmap()
try_to_unmap_cluster() does:
for (pte = pte_offset_map(pmd, address);
address < end; pte++, address += PAGE_SIZE) {
...
}
pte_unmap(pte);
It may take a little staring to notice, but pte can actually fall off the
end of the pte page in this iteration, which makes life difficult for
kmap_atomic() and the users not expecting it to BUG(). Of course, we're
somewhat lucky in that arithmetic elsewhere in the function guarantees that
at least one iteration is made, lest this force larger rearrangements to be
made. This issue and patch also apply to non-mm mainline and with trivial
adjustments, at least two related kernels.
Discovered during internal testing at Oracle.

[TCP]: Fix stretch ACK performance killer when doing ucopy.
When we are doing ucopy, we try to defer the ACK generation to
cleanup_rbuf(). This works most of the time very well, but if the
ucopy prequeue is large, this ACKing behavior kills performance.
With TSO, it is possible to fill the prequeue so large that by the
time the ACK is sent and gets back to the sender, most of the window
has emptied of data and performance suffers significantly.
This behavior does help in some cases, so we should think about
re-enabling this trick in the future, using some kind of limit in
order to avoid the bug case.

The latest speedbumped Apple G5 models have a "bug" in the Open Firmware
device tree that lacks the proper interrupt routing information for the

because of that :), our driver didn't properly check and crashes :(

[PATCH] fix for __generic_file_aio_read() to return 0 on EOF
I came across the following problem while running ltp-aiodio testcases from
ltp-full-20050405 on linux-2.6.12-rc3-mm3. I tried running the tests with
EXT3 as well as JFS filesystems.
One or two fsx-linux testcases were hung after some time. These testcases
were hanging at wait_for_all_aios().
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] 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/posixtest...
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).

[PATCH] cpusets+hotplug+preepmt broken
This patch removes the entwining of cpusets and hotplug code in the "No
more Mr. Nice Guy" case of sched.c move_task_off_dead_cpu().
Since the hotplug code is holding a spinlock at this point, we cannot take
the cpuset semaphore, cpuset_sem, as would seem to be required either to
update the tasks cpuset, or to scan up the nested cpuset chain, looking for
the nearest cpuset ancestor that still has some CPUs that are online. So
we just punt and blast the tasks cpus_allowed with all bits allowed.
This reverts these lines of code to what they were before the cpuset patch.
And it updates the cpuset Doc file, to match.
The one known alternative to this that seems to work came from Dinakar
Guniguntala, and required the hotplug code to take the cpuset_sem semaphore
much earlier in its processing. So far as we know, the increased locking
entanglement between cpusets and hot plug of this alternative approach is
not worth doing in this case.

[SCSI] aic7xxx: make correct use of slave_alloc/destroy and remove the per device timer
The allocation of all of our components should be done in slave alloc.
Currently it's rather fancifully refcounted in the queuecommand
callback. This patch moves allocation and destroy to their correct
places in slave_alloc/slave_destory. Now we can guarantee that
everywhere a device is requested, it's actually been allocated, so don't
check for this anymore.
Additionally, the per device busy timer was the only source of potential
use after free. It's been deleted because Linux does the correct thing
with busy returns, so there's no need to implement a separate timer in
the driver.
Finally, implement code that forces all the device parameters to zero
(i.e. async and narrow) in the slave alloc, inform the spi class of the
bios recorded maximums and wait until slave configure before trying

On ppc32, the platform code can supply a "progress" function that is
used to show progress through the boot. These functions are usually
in an init section and so can't be called after the init pages are

is booted (for hotplug cpu) we can get the situation where the
progress function can be called after boot. The simple fix is to set
the progress function pointer to NULL when the init pages are freed,
and that is what this patch does (note that all callers already check

[IPV4/IPV6] Ensure all frag_list members have NULL sk
Having frag_list members which holds wmem of an sk leads to nightmares
with partially cloned frag skb's. The reason is that once you unleash
a skb with a frag_list that has individual sk ownerships into the stack
you can never undo those ownerships safely as they may have been cloned
by things like netfilter. Since we have to undo them in order to make
skb_linearize happy this approach leads to a dead-end.
So let's go the other way and make this an invariant:
For any skb on a frag_list, skb->sk must be NULL.
That is, the socket ownership always belongs to the head skb.
It turns out that the implementation is actually pretty simple.
The above invariant is actually violated in the following patch
for a short duration inside ip_fragment. This is OK because the
offending frag_list member is either destroyed at the end of the
slow path without being sent anywhere, or it is detached from
the frag_list before being sent.

It looks like skb_cow_data() does not set
proper owner for newly created skb.
If we have several fragments for skb and some of them
are shared(?) or cloned (like in async IPsec) there
might be a situation when we require recreating skb and
thus using skb_copy() for it.
Newly created skb has neither a destructor nor a socket
assotiated with it, which must be copied from the old skb.
As far as I can see, current code sets destructor and socket
for the first one skb only and uses truesize of the first skb
only to increment sk_wmem_alloc value.
If above "analysis" is correct then attached patch fixes that.

[TG3]: Add tagged status support.
When supported, use the TAGGED interrupt processing support
the chip provides. In this mode, instead of a "on/off" binary
semaphore, an incrementing tag scheme is used to ACK interrupts.
All MSI supporting chips support TAGGED mode, so the tg3_msi()
interrupt handler uses it unconditionally. This invariant is
verified when MSI support is tested.
Since we can invoke tg3_poll() multiple times per interrupt under
high packet load, we fetch a new copy of the tag value in the
status block right before we actually do the work.
Also, because the tagged status tells the chip exactly which
work we have processed, we can make two optimizations:
1) tg3_restart_ints() need not check tg3_has_work()
2) the tg3_timer() need not poke the chip 10 times per
second to keep from losing interrupt events

[PATCH] Fix filp being passed through raw ioctl handler
Don't pass meaningless file handles to block device ioctls.
The recent raw IO ioctl-passthrough fix started passing the raw file
handle into the block device ioctl handler. That's unlikely to be
useful, as the file handle is actually open on a character-mode raw
device, not a block device, so dereferencing it is not going to yield
useful results to a block device ioctl handler.
Previously we just passed NULL; also not a value that can usefully
be dereferenced, but at least if it does happen, we'll oops instead of
silently pretending that the file is a block device, so NULL is the more
defensive option here. This patch reverts to that behaviour.

[PATCH] Avoid console spam with ext3 aborted journal.
Avoid console spam with ext3 aborted journal.
ext3 usually reports error conditions that it detects in its environment.
But when its journal gets aborted due to such errors, it can sometimes
continue to report that condition forever, spamming the console to such
an extent that the initial first cause of the journal abort can be lost.
When the journal aborts, we put the filesystem into readonly mode. Most
subsequent filesystem operations will get rejected immediately by checks
for MS_RDONLY either in the filesystem or in the VFS. But some paths do
not have such checks --- for example, if we continue to write to a file
handle that was opened before the fs went readonly. (We only check for
the ROFS condition when the file is first opened.) In these cases, we
can continue to generate log errors similar to
EXT3-fs error (device $DEV) in start_transaction: Journal has aborted
for each subsequent write.
There is really no point in generating these errors after the initial
error has been fully reported. Specifically, if we're starting a
completely new filesystem operation, and the filesystem is *already*
readonly (ie. the ext3 layer has already detected and handled the
underlying jbd abort), and we see an EROFS error, then there is simply
no point in reporting it again.

[PATCH] CPCI: update
I have finally done some work to update the CompactPCI hotplug driver to
fix some of the outstanding issues in 2.6:
- Added adapter and latch status ops so that those files will get created
by the current PCI hotplug core. This used to not be required, but
seems to be now after some of the sysfs rework in the core.
- Replaced slot list spinlock with a r/w semaphore to avoid any potential
issues with sleeping. This quiets all of the runtime warnings.
- Reworked interrupt driven hot extraction handling to remove need for a
polling operator for ENUM# status. There are a lot of boards that only
have an interrupt driven by ENUM#, so this lowers the bar to entry.
- Replaced pci_visit_dev usage with better use of the PCI core functions.
The new code is functionally equivalent to the previous code, but the
use of pci_enable_device on insert needs to be investigated further, as
I need to do some more testing to see if it is still necessary.

[PATCH] block_read_full_page() get_block() error handling fix
If block_read_full_page() detects an error when running get_block() it will
run SetPageError(), then it will zero out the block in pagecache and will mark
the buffer_head uptodate.
So at the end of readahead we end up with a non-uptodate pagecache page which
is marked PageError. But it has uptodate buffers.
The pagefault code will run ClearPageError, will launch readpage a second time
and block_read_full_page() will notice the uptodate buffers and will mark the
page uptodate as well. We end up with an uptodate, !PageError page full of
zeros and the error is lost.
(It seems a little odd that filemap_nopage() runs ClearPageError(). I guess
all of this adds up to meaning that for each attempted access to the page, the
pagefault handler will retry the I/O. Which is good and bad. If the app is
ignoring SIGBUS for some reason we could get a lot of back-to-back I/O
errors.)
Fix it by not marking the pagecache buffer_head as uptodate if the attempt to
map that buffer to a disk block failed.

[PATCH] selinux: fix avc_alloc_node() oom with no policy loaded
This patch should fix the avc_alloc_node() oom condition that Andrew
reported when no policy is loaded in SELinux.
Prior to this patch, when no policy was loaded, the SELinux "security
server" (policy engine) was only returning allowed decisions for the
requested permissions for each access check. This caused the cache to
thrash when trying to use SELinux for real work with no policy loaded
(typically, the no policy loaded state is only for bootstrapping to the
point where we can load an initial policy).
This patch changes the SELinux security server to return the complete
allowed access vector at once, and then to reset the cache after the
initial policy load to flush the initial cache state created during
bootstrapping.

[PATCH] CDRW/DVD packet writing data corruption fix
I found a bug in the packet writing driver that could cause data
corruption. The problem arised if the driver got a write request for a
sector in a "zone" it was already working on. In that case it was supposed
to queue the write request until it was done processing earlier requests
for the same zone, and instead work on some other zone in the mean time.
However, if there was no other zone to work on, the driver would initiate
two packet_data objects for the same zone, causing unpredictable things to
happen.

[PATCH] spurious interrupt fix
On my IA64 machine, after kernel 2.6.12-rc3 boots, an edge-triggered
interrupt (IRQ 46) keeps triggered over and over again. There is no IRQ 46
interrupt action handler. It has lots of impact on performance.
Kernel 2.6.10 and its prior versions have no the problem. Basically,
kernel 2.6.10 will mask the spurious edge interrupt if the interrupt is
triggered for the second time and its status includes
IRQ_DISABLE|IRQ_PENDING.
Originally, IA64 kernel has its own specific _irq_desc definitions in file
arch/ia64/kernel/irq.c. The definition initiates _irq_desc[irq].status to
IRQ_DISABLE. Since kernel 2.6.11, it was moved to architecture independent
codes, i.e. kernel/irq/handle.c, but kernel/irq/handle.c initiates
_irq_desc[irq].status to 0 instead of IRQ_DISABLE.

- Remove unused P6 definitions
- Add support for performance counter based watchdog on P4 systems.
This allows to run it only once per second, which saves some CPU time.
Previously it would run at 1000Hz, which was too much.
Code ported from i386
Make this the default on Intel systems.
- Use check_nmi_watchdog with local APIC based nmi
- Fix race in touch_nmi_watchdog
- Fix bug that caused incorrect performance counters to be programmed in a
few cases on K8.
- Remove useless check for local APIC
- Use local_t and per_cpu variables for per CPU data.
- Keep other CPUs busy during check_nmi_watchdog to make sure they really
tick when in lapic mode.
- Only check CPUs that are actually online.

This patch removes the assumption that LAPIC entries contain the BSP as its

- Removes assumption that LAPIC entries contain BSP first.
- Builds x86_acpiid_to_apicid[] and bios_cpu_apicid[] properly with BSP as
first entry.
- Made maxcpus=1 boot on these systems. Since the parsing earlier in
arch/x86_64/kernel/mpparse.c stopped after maxcpus entries, other entries
were not processed, this causes kernel not to boot on these systems.
TBD: x86_acpiid_to_apicid and bios_cpu_apicid[] seem to be exactly the
same. This could be removed, but might need more work to cleanup.

[PATCH] x86_64: Add pmtimer support
There are unfortunately more and more multi processor Opteron systems which
don't have HPET timer support in the southbridge. This covers in particular
Nvidia and VIA chipsets. They also don't guarantee that the TSCs are
synchronized between CPUs; and especially with MP powernow the systems are
nearly unusable because the time gets very inconsistent between CPUs.
The timer code for x86-64 was originally written under the assumption that we
could fall back to the HPET timer on such systems. But this doesn't work
there.
Another alternative is to use the ACPI PM timer as primary time source. This
patch does that. The kernel only uses PM timer when there is no other choice
because it has some disadvantages.
Ported over from i386. It should be faster than the i386 version because I
dropped the "read three times" workaround, but is still considerable slower
than HPET and also does not work together with vsyscalls which have to be
disabled.

[PATCH] x86_64: Update TSC sync algorithm
The new TSC sync algorithm recently submitted did not work too well.
The result was that some MP machines where the TSC came up of the BIOS very
unsynchronized and that did not have HPET support were nearly unusable because
the time would jump forwards and backwards between CPUs.
After a lot of research ;-) and some more prototypes I ended up with just
using the one from IA64 which looks best. It has some internal self tuning
that should adapt to changing interconnect latencies. It holds up in my tests
so far.
I believe it was originally written by David Mosberger, I just ported it over
to x86-64. See the inline comment for a description.
This cleans up the code because it uses smp_call_function for syncing instead
of having custom hooks in SMP bootup.
Please note that the cycle numbers it outputs are too optimistic because they
do not take into account the latency of WRMSR and RDTSC, which can be hundreds
of cycles. It seems to be able to sync a dual Opteron to 200-300 cycles,
which is probably good enough.
There is a timing window during AP bootup where interrupts can see
inconsistent time before the TSC is synced. It is hard to avoid unfortunately
because we can only do the TSC sync after some setup, and we need to enable
interrupts before that. I just ignored it for now.

kseriod take care of it. Otherwise we may attempt to unregister associated
input devices which will generate hotplug events which are not handled well
during swsusp.

[PATCH] USB: usbnet driver fixes
Updates to the usbnet driver:
- Remove a warning when built with Zaurus support but not CDC Ethernet;
just moves an #ifdef to cover more code
- Two tweaks to the pseudo-MDLM support:
* correctly handle _either_ of the two GUIDs
* ignore a padding bit that doesn't seem necessary
- Remove ID for one Motorola phone that uses the MDLM stuff.
It also updates the Kconfig helptext to make it clearer that the "Zaurus"
configuration option supports an increasing (sigh) family of nonstandard
peripheral protocols.

[PATCH] Fix root hole in pktcdvd
ioctl_by_bdev may only be used INSIDE the kernel. If the "arg" argument
refers to memory that is accessed by put_user/get_user in the ioctl
function, the memory needs to be in the kernel address space (that's the
set_fs(KERNEL_DS) doing in the ioctl_by_bdev). This works on i386 because
even with set_fs(KERNEL_DS) the user space memory is still accessible with
put_user/get_user. That is not true for s390. In short the ioctl
implementation of the pktcdvd device driver is horribly broken.

[PATCH] Fix root hole in raw device
[Patch] Fix raw device ioctl pass-through
Raw character devices are supposed to pass ioctls through to the block
devices they are bound to. Unfortunately, they are using the wrong
function for this: ioctl_by_bdev(), instead of blkdev_ioctl().
ioctl_by_bdev() performs a set_fs(KERNEL_DS) before calling the ioctl,
redirecting the user-space buffer access to the kernel address space.
This is, needless to say, a bad thing.
This was noticed first on s390, where raw IO was non-functioning. The
s390 driver config does not actually allow raw IO to be enabled, which
was the first part of the problem. Secondly, the s390 kernel address
space is distinct from user, causing legal raw ioctls to fail. I've
reproduced this on a kernel built with 4G:4G split on x86, which fails
in the same way (-EFAULT if the address does not exist kernel-side;
returns success without actually populating the user buffer if it does.)
The patch below fixes both the config and address-space problems. It's
based closely on a patch by Jan Glauber <jang@de.ibm.com>, which has
been tested on s390 at IBM. I've tested it on x86 4G:4G (split address
space) and x86_64 (common address space).
Kernel-address-space access has been assigned CAN-2005-1264.

[PATCH] libata: Prevent the interrupt handler from completing a command twice
Problem:
During the libata CD-ROM stress test, sometimes the "BUG: timeout
without command" error is seen.
Root cause:
Unexpected interrupt occurs after the ata_qc_complete() is called,
but before the SCSI error handler. The interrupt handler is invoked
before the SCSI error handler, and it clears the command by calling
ata_qc_complete() again. Later when the SCSI error handler is run,
the ata_queued_cmd is already gone, causing the "BUG: timeout without
command" error.
Changes:
- Use the ATA_QCFLAG_ACTIVE flag to prevent the interrupt handler
from completing the command twice, before the scsi_error_handler.
