This is a quick hack to overcome the fact that SRCU currently does not
allow static initializers, and we need to sometimes initialize those
things before any other initializers (even "core" ones) can do so.
Currently we don't allow this at all for modules, and the only user that
needs is right now is cpufreq. As reported by Thomas Gleixner:
"Commit b4dfdbb3c707474a2254c5b4d7e62be31a4b7da9 ("[PATCH] cpufreq:

This reverts commit 37605a6900f6b4d886d995751fcfeef88c4e462c.
Again.
This same bug has now been introduced twice: it was done earlier by
commit b8d35192c55fb055792ff0641408eaaec7c88988, only to be reverted
last time in commit 72945b2b90a5554975b8f72673ab7139d232a121.
We must NOT try to queue up notify handlers to another thread than the
normal ACPI execution thread, because the notifications on some systems
seem to just keep on accumulating until we run out of memory and/or
threads.
Keeping events within the one deferred execution thread automatically
throttles the events properly.
At least the Compaq N620c will lock up completely on the first thermal
event without this patch reverted.

When showing the stack backtrace, make sure that we never accept not
only an unchanging frame pointer, but also a frame pointer that moves
back down the stack frame. It must always grow up (toward older stack
frames).
I doubt this has triggered, but a subtly corrupt stack with extremely
unlucky contents could cause us to loop forever on a bogus endless frame
pointer chain.
This review was triggered by much worse problems happening in some of
the other stack unwinding code.

The scheduler on Andreas Friedrich's hyperthreading system stopped
working properly: the scheduler would never move tasks to another CPU!
The lask known working kernel was 2.6.8.
After a couple of attempts to corner the bug, the following smoking gun
was found:

[<c01004d7>] init+0x146/0x2fd
[<c0103a87>] kernel_thread_helper+0x7/0x10
a quick look at cpu_idle_wait() shows how broken that code is
on i386: it changes the init task's affinity map but never
restores it ...
and because all userspace tasks get forked by init, they all
inherited that single-CPU affinity mask. x86_64 cloned this
bug too.

this crash happened because it did not sanitize the dwarf2 data it
got, and got an unaligned stack pointer - which happily walked past
the process stack (and eventually reached the end of kernel memory
and pagefaulted there) due to this naive iteration condition:
HANDLE_STACK (((long) stack & (THREAD_SIZE-1)) != 0);
note that i386 is alot more conservative when it comes to trusting
stack pointers:
static inline int valid_stack_ptr(struct thread_info *tinfo, void *p)
{
return p > (void *)tinfo &&
p < (void *)tinfo + THREAD_SIZE - 3;
}
but the x86_64 code did not take this bit of i386 code.
The fix is to align the stack pointer.

Benh points out that the msgs[0].flags entry never got initialized, and
since it's an automatic stack allocation, it could have any random
value, which is bad.
Rewrite the initializer to explicitly initialize all fields of the small
i2c_msg structure array we generate. Just to keep it all obvious, let's
handle msgs[1].buf in the same initializer while we're at it, instead of
initializing that one separately later.

similar to the version in adbhid_input_register(): The '<>' key and the
'^°' key on a german keyboard is swapped. Provide correct keys to
userland, external USB keyboards will not work correctly when the
'badmap'/'goodmap' workarounds from xkeyboard-config are used.
It is expected that distributions drop the badmap/goodmap part from
keycodes/macintosh in the xkeyboard-config package.
This is probably 2.6.18.x material, if major distros settle on 2.6.18.

<0>Kernel panic - not syncing: Aiee, killing interrupt handler!
The root cause is that some irq_chip variables, especially ia64_msi_chip,
initiate their memeber end to point to NULL. __do_IRQ doesn't check
if irq_chip->end is null and just calls it after processing the interrupt.
As irq_chip->end is called at many places, so I fix it by reinitiating
irq_chip->end to dummy_irq_chip.end, e.g., a noop function.

The root cause is the device struct is initialized twice.
If the device is allocated dynamically by platform_device_alloc,
platform_device_alloc will initialize struct device, then,
platform_device_add should be used to register the device.
The difference between platform_device_register and platform_device_add is
platform_device_register will initiate the device while platform_device_add
won't.

This also kills XT_SO_* because {ip,ip6,arp}_tables doesn't have so much

The old userland tools keep to behave as ever, because old kernel always

Based on patch by James D. Nurmi:
I've got some code very dependant on nfnetlink_queue, and turned up a
large number of warns coming from skb_trim. While it's quite possibly
my code, having not seen it on older kernels made me a bit suspect.
Anyhow, based on some googling I turned up this thread:
http://lkml.org/lkml/2006/8/13/56
And believe the issue to be related, so attached is a small patch to
the kernel -- not sure if this is completely correct, but for anyone
else hitting the WARN_ON(1) in skbuff.h, it might be helpful..

The windfarm code, in it's current incarnation, uses request_module() to
load the various submodules it needs for a given platform so that only
the main platform control module needs to be modprobed. However, it was
missing various bits. This fixes it. In the future, we'll use some
hotplug mecanisms to try to get all of this auto-loaded on the platforms
where it matters but that isn't ready yet.

When called to do a transfer that has a start offset within the cache
line which is uneven between source and destination and a length which
terminates the source of the copy exactly on a cache line, one extra
line gets copied into a temporary buffer. This is normally not an issue
since the buffer is a kernel buffer and only the requested information
gets copied into the user buffer.
The problem arises when the source ends at the very last physical page
of memory. That last cache line does not exist and results in the SHUB
chip raising an MCA.

Komuro reports that ISA interrupts do not work after a disable_irq(),
causing some PCMCIA drivers to not work, with messages like
eth0: Asix AX88190: io 0x300, irq 3, hw_addr xx:xx:xx:xx:xx:xx
eth0: found link beat
eth0: autonegotiation complete: 100baseT-FD selected
eth0: interrupt(s) dropped!
eth0: interrupt(s) dropped!
eth0: interrupt(s) dropped!
...
Linus Torvalds <torvalds@osdl.org> said:
"Now, edge-triggered interrupts are a _lot_ harder to mask, because the
Intel APIC is an unbelievable piece of sh*t, and has the edge-detect logic
_before_ the mask logic, so if a edge happens _while_ the device is
masked, you'll never ever see the edge ever again (unmasking will not
cause a new edge, so you simply lost the interrupt).
So when you "mask" an edge-triggered IRQ, you can't really mask it at all,
because if you did that, you'd lose it forever if the IRQ comes in while
you masked it. Instead, we're supposed to leave it active, and set a flag,
and IF the IRQ comes in, we just remember it, and mask it at that point
instead, and then on unmasking, we have to replay it by sending a
self-IPI."
This trivial patch solves the problem.

This reverts commit 0130b0b32ee53dc7add773fcea984f6a26ef1da3.
Sergey Vlasov points out (and Vadim Lobanov concurs) that the bug it was
supposed to fix must be some unrelated memory corruption, and the "fix"
actually causes more problems:
"However, the new code does not look safe in all cases. If some other
task has opened more files while dup_fd() released oldf->file_lock, the
new code will update open_files to the new larger value. But newf was
allocated with the old smaller value of open_files, therefore subsequent
accesses to newf may try to write into unallocated memory."
so revert it.

When building a monolithic kernel, the load order of drivers does not
work for SAS libata users, resulting in a kernel oops.
Convert libata to use subsys_initcall instead of module_init, which
ensures that libata gets loaded before any LLDD.
This is the same thing that scsi core does to solve the problem. The
load order problem was observed on ipr SAS adapters and should exist for
other SAS users as well.

Unlike mmap(), the codepath for brk() creates a vma without first checking
that it doesn't touch a region exclusively reserved for hugepages. On
powerpc, this can allow it to create a normal page vma in a hugepage
region, causing oopses and other badness.
Add a test to prevent this. With this patch, brk() will simply fail if it
attempts to move the break into a hugepage reserved region.

(David:)
If hugetlbfs_file_mmap() returns a failure to do_mmap_pgoff() - for example,
because the given file offset is not hugepage aligned - then do_mmap_pgoff
will go to the unmap_and_free_vma backout path.
But at this stage the vma hasn't been marked as hugepage, and the backout path
will call unmap_region() on it. That will eventually call down to the
non-hugepage version of unmap_page_range(). On ppc64, at least, that will
cause serious problems if there are any existing hugepage pagetable entries in
the vicinity - for example if there are any other hugepage mappings under the
same PUD. unmap_page_range() will trigger a bad_pud() on the hugepage pud
entries. I suspect this will also cause bad problems on ia64, though I don't
have a machine to test it on.
(Hugh:)
prepare_hugepage_range() should check file offset alignment when it checks
virtual address and length, to stop MAP_FIXED with a bad huge offset from
unmapping before it fails further down. PowerPC should apply the same
prepare_hugepage_range alignment checks as ia64 and all the others do.
Then none of the alignment checks in hugetlbfs_file_mmap are required (nor
is the check for too small a mapping); but even so, move up setting of
VM_HUGETLB and add a comment to warn of what David Gibson discovered - if
hugetlbfs_file_mmap fails before setting it, do_mmap_pgoff's unmap_region
when unwinding from error will go the non-huge way, which may cause bad
behaviour on architectures (powerpc and ia64) which segregate their huge
mappings into a separate region of the address space.

The vgetcpu per CPU initialization previously relied on CPU hotplug
events for all CPUs to initialize the per CPU state. That only
worked only on kernels with CONFIG_HOTPLUG_CPU enabled. On the
others some CPUs didn't get their state initialized properly
and vgetcpu wouldn't work.
Change the initialization sequence to instead run in a normal
initcall (which runs after the normal CPU bootup) and initialize
all running CPUs there. Later hotplug CPUs are still handled
with an hotplug notifier.
This actually simplifies the code somewhat.

x86_64: setup saved_max_pfn correctly
2.6.19-rc4 has broken CONFIG_CRASH_DUMP support on x86_64. It is impossible
to read out the kernel contents from /proc/vmcore because saved_max_pfn is set
to zero instead of the max_pfn value before the user map is setup.
This happens because saved_max_pfn is initialized at parse_early_param() time,
and at this time no active regions have been registered. save_max_pfn is setup
from e820_end_of_ram(), more exact find_max_pfn_with_active_regions() which
returns 0 because no regions exist.
This patch fixes this by registering before and removing after the call
to e820_end_of_ram().

Stephen Tweedie, Herbert Xu, and myself have been struggling with a very
nasty bug in Xen. But it also pointed out a small bug in the x86_64
kernel boot setup.
The GDT limit being setup by the initial bzImage code when entering into
protected mode is way too big. The comment by the code states that the
size of the GDT is 2048, but the actual size being set up is much bigger
(32768). This happens simply because of one extra '0'.
Instead of setting up a 0x800 size, 0x8000 is set up. On bare metal this
is fine because the CPU wont load any segments unless they are
explicitly used. But unfortunately, this breaks Xen on vmx FV, since it
(for now) blindly loads all the segments into the VMCS if they are less
than the gdt limit. Since the real mode segments are around 0x3000, we are
getting junk into the VMCS and that later causes an exception.
Stephen Tweedie has written up a patch to fix the Xen side and will be
submitting that to those folks. But that doesn't excuse the GDT limit
being a magnitude too big.

A curious thing happens, however, when ata_qc_new_init fails to get
an ata_queued_cmd:
First, ata_qc_new_init handles the failure like this:
cmd->result = (DID_OK << 16) | (QUEUE_FULL << 1);
done(cmd);
Then, we return to ata_scsi_translate and do this:
err_mem:
cmd->result = (DID_ERROR << 16);
done(cmd);
It appears to me that first we set a status code indicating that we're
ok but the device queue is full and finish the command, but then
we blow away that status code and replace it with an error flag and
finish the command a second time! That does not seem to be desirable
behavior since we merely want the I/O to wait until a command slot
frees up, not send errors up the block layer.
In the err_mem case, we should simply exit out of ata_scsi_translate
instead.

When ib_cancel_mad() is called, it puts the canceled send on a list
and schedules a "flushed" callback from process context. However,
this leaves a window where a receive completion could be processed
before the send is fully flushed.
This is fine, except that ib_find_send_mad() will find the MAD and
return it to the receive processing, which results in the sender
getting both a successful receive and a "flushed" send completion for
the same request. Understandably, this confuses the sender, which is
expecting only one of these two callbacks, and leads to grief such as
a use-after-free in IPoIB.
Fix this by changing ib_find_send_mad() to return a send struct only
if the status is still successful (and not "flushed"). The search of
the send_list already had this check, so this patch just adds the same
check to the search of the wait_list.

This patch (as810c) copies a minimum of 36 bytes of INQUIRY data, even if
the device claims that not all of them are valid. Often badly behaved
devices put plausible data in the Vendor, Product, and Revision strings but
set the Additional Length byte to a small value. Using potentially valid
data is certainly better than allocating a short buffer and then reading
beyond the end of it, which is what we do now.

While testing kernel on machine with "irqpoll" option I've caught such a
lockup:
__do_IRQ()
spin_lock(&desc->lock);
desc->chip->ack(); /* IRQ is ACKed */
note_interrupt()
misrouted_irq()
handle_IRQ_event()
if (...)
local_irq_enable_in_hardirq();
/* interrupts are enabled from now */
...
__do_IRQ() /* same IRQ we've started from */
spin_lock(&desc->lock); /* LOCKUP */
Looking at misrouted_irq() code I've found that a potential deadlock like
this can also take place:
1CPU:
__do_IRQ()
spin_lock(&desc->lock); /* irq = A */
misrouted_irq()
for (i = 1; i < NR_IRQS; i++) {
spin_lock(&desc->lock); /* irq = B */
if (desc->status & IRQ_INPROGRESS) {
2CPU:
__do_IRQ()
spin_lock(&desc->lock); /* irq = B */
misrouted_irq()
for (i = 1; i < NR_IRQS; i++) {
spin_lock(&desc->lock); /* irq = A */
if (desc->status & IRQ_INPROGRESS) {
As the second lock on both CPUs is taken before checking that this irq is
being handled in another processor this may cause a deadlock. This issue
is only theoretical.
I propose the attached patch to fix booth problems: when trying to handle
misrouted IRQ active desc->lock may be unlocked.

The problem is because of race window. When if(expand) block is executed in
dup_fd unlocking of oldf->file_lock give a window for fdtable in oldf to be
modified. So actual open_files in oldf may not match with open_files

If you call set_personality() with an expression such as:

then this evaluates to:
((current->personality == foo ? PERS_FOO1 : PERS_FOO2) ? ...

The PCI sysfs attributes are created after the initial PCI bus scan. With
the addition of more return value checking and assertions in the device and
sysfs layers we now can get dumps like this on sparc64:

[ 20.135514] PCI0(PBMB): Bus running at 33MHz
It's triggering because removal of the "config" PCI sysfs file for the
device fails.
On sparc64, after probing the device, we'll delete the PCI device via
pci_remove_bus_device() if we cannot find the firmware device tree node
corresponding to it.
This is fine, but at this point the sysfs files for the PCI device won't be
setup yet.
So we should not try to do anything in pci_remove_sysfs_dev_files() if
pci_sysfs_init() has not run yet.

The previous fixes for the use after free in xfs_iunpin left a nasty log
deadlock when xfslogd unpinned the inode and dropped the last reference to
the inode. the ->clear_inode() method can issue transactions, and if the
log was full, the transaction could push on the log and get stuck trying
to push the inode it was currently unpinning.
To fix this, we provide xfs_iunpin a guarantee that it will always have a
valid xfs_inode <-> linux inode link or a particular flag will be set on
the inode. We then use log forces during lookup to ensure transactions are
completed before we recycle the inode. This ensures that xfs_iunpin will
never use the linux inode after it is being freed, and any lookup on an
inode on the reclaim list will wait until it is safe to attach a new linux
inode to the xfs inode.

The enablement of 64k pages on pseries platforms exposed a bug in
the RTAS mechanism for updating firmware. RTAS assumes 4k for flash
block and list sizes, and use of any other sizes results in a failure,
even though PAPR does not specify any such requirement.
This patch changes the rtas_flash module to force the use of 4k memory
block and list sizes when preparing and sending a firmware image to
RTAS. The rtas_flash function now uses a slab cache of 4k blocks with
4k alignment, rather than get_zeroed_page(), to allocate the memory for
the flash blocks and lists. The 4k alignment requirement is specified
in PAPR.

that we think the device is programmed with instead of reading it back from
the hardware. Which simplifies the code a little and should speed things up a
bit.

architecture read/write routines to update this code.

A wrong function was being used to free a list; this fixes the problem.
Otherwise, an oops at unload time was possible. But not likely, since you
can't have any users when you unload the modules and it is very hard to get
messages into this queue without users.

The basic issue is that despite have been deprecated and warned about as a
very bad thing in the man pages since its inception there are a few real
users of sys_sysctl. It was my assumption that because sysctl had been
deprecated for all of 2.6 there would be no user space users by this point,
so I initially gave sys_sysctl a very short deprecation period.
Now that I know there are a few real users the only sane way to proceed
with deprecation is to push the time limit out to a year or two work and
work with distributions that have big testing pools like fedora core to
find these last remaining users.
Which means that the sys_sysctl interface needs to be maintained in the
meantime.
Since I have provided a technical measure that allows us to add new sysctl
entries without reserving more binary numbers I believe that is enough to
fix the sys_sysctl binary interface maintenance problems, because there is
no longer a need to change the binary interface at all.
Since the sys_sysctl implementation needs to stay around for a while and
the worst of the maintenance issues that caused us to occasionally break
the ABI have been addressed I don't see any advantage in continuing with
the removal of sys_sysctl.
So instead of merely increasing the deprecation period this patch removes
the deprecation of sys_sysctl and modifies the kernel to compile the code
in by default.
With committing to maintain sys_sysctl we get all of the advantages of a
fast interface for anything that needs it. Currently sys_sysctl is about
5x faster than /proc/sys, for the same string data.

When ACPI && NUMA, pxm_to_node is used and it exists in drivers/acpi/numa.c
Tony said:
The patch makes sense ... if you pick both of "ACPI" and "NUMA", then you
need (and should automatically be given) ACPI_NUMA too.
The only open question is whether there is a better way of getting there.
Perhaps with less configuration options in the first place? We are heading
towards a future where so many systems will be NUMA that there would seem to
be little benefit in keeping ACPI_NUMA separate from ACPI ... but perhaps
we aren't quite there yet.

There are two bugs in the kretprobe-booster.
1) It doesn't make room for gs registers.
2) It doesn't change status of the current kprobe. This status will
effect the fault handling.
This patch fixes these bugs and, additionally, saves skipped registers for
compatibility with the original kretprobe.

If there's a swap file on a software RAID, it should be possible to use this
file for saving the swsusp's suspend image. Also, this file should be
available to the memory management subsystem when memory is being freed before
the suspend image is created.
For the above reasons it seems that md_threads should not be frozen during the
suspend and the appended patch makes this happen, but then there is the
question if they don't cause any data to be written to disks after the suspend
image has been created, provided that all filesystems are frozen at that time.

It turns out that CHANGE is preferred to ONLINE/OFFLINE for various reasons
(not least of which being that udev understands it already).
So remove the recently added KOBJ_OFFLINE (no-one is likely to care anyway)
and change the ONLINE to a CHANGE event

All device-mapper targets must complete outstanding I/O before suspending.
The mirror target generates I/O in its recovery phase and fails to wait for
it. It needs to be tracked so we can ensure that it has completed before we
suspend.

If the device is already suspended, just return the error and skip the code
that would incorrectly wipe md->suspended_bdev.

There is a race between dev_create() and find_device().
If the mdptr has not yet been stored against a device, find_device() needs to
behave as though no device was found. It already returns NULL, but there is a
dm_put() missing: it must drop the reference dm_get_md() took.
The bug was introduced by dm-fix-mapped-device-ref-counting.patch.
It manifests itself if another dm ioctl attempts to reference a newly-created
device while the device creation ioctl is still running. The consequence is
that the device cannot be removed until the machine is rebooted. Certain udev
configurations can lead to this happening.

o Currently there is no specific alignment restriction in linker script
and in some cases it can be placed non 4K aligned addresses. This fails
kexec which checks that segment to be loaded is page aligned.

In the case where an open creates the file, we shouldn't be rechecking
permissions to open the file; the open succeeds regardless of what the new
file's mode bits say.
This patch fixes the problem, but only by introducing yet another parameter
to nfsd_create_v3. This is ugly. This will be fixed by later patches.
