12 years agoRemove fs.h from mm.h
Alexey Dobriyan [Sun, 29 Jul 2007 22:36:13 +0000]
Remove fs.h from mm.h

Remove fs.h from mm.h. For this,
 1) Uninline vma_wants_writenotify(). It's pretty huge anyway.
 2) Add back fs.h or less bloated headers (err.h) to files that need it.

As result, on x86_64 allyesconfig, fs.h dependencies cut down from 3929 files
rebuilt down to 3444 (-12.3%).

Cross-compile tested without regressions on my two usual configs and (sigh):

12 years agoIntroduce CONFIG_SUSPEND for suspend-to-Ram and standby
Rafael J. Wysocki [Sun, 29 Jul 2007 21:27:18 +0000]
Introduce CONFIG_SUSPEND for suspend-to-Ram and standby

Introduce CONFIG_SUSPEND representing the ability to enter system sleep
states, such as the ACPI S3 state, and allow the user to choose SUSPEND
and HIBERNATION independently of each other.

Make HOTPLUG_CPU be selected automatically if SUSPEND or HIBERNATION has
been chosen and the kernel is intended for SMP systems.

Also, introduce CONFIG_PM_SLEEP which is automatically selected if
CONFIG_SUSPEND or CONFIG_HIBERNATION is set and use it to select the
code needed for both suspend and hibernation.

The top-level power management headers and the ACPI code related to
suspend and hibernation are modified to use the new definitions (the
changes in drivers/acpi/sleep/main.c are, mostly, moving code to reduce
the number of ifdefs).

There are many other files in which CONFIG_PM can be replaced with
CONFIG_PM_SLEEP or even with CONFIG_SUSPEND, but they can be updated in
the future.

12 years agoProvide timespec to guests rather than jiffies clock.
Rusty Russell [Fri, 27 Jul 2007 03:42:52 +0000]
Provide timespec to guests rather than jiffies clock.

A non-periodic clock_event_device and the "jiffies" clock don't mix well:
tick_handle_periodic() can go into an infinite loop.

Currently lguest guests use the jiffies clock when the TSC is
unusable.  Instead, make the Host write the current time into the lguest
page on every interrupt.  This doesn't cost much but is more precise
and at least as accurate as the jiffies clock.  It also gets rid of
the GET_WALLCLOCK hypercall.

Also, delay setting sched_clock until our clock is set up, otherwise
the early printk timestamps can go backwards (not harmful, just ugly).

Fix lguest bzImage loading with CONFIG_RELOCATABLE=y

Jason Yeh sent his crashing .config: bzImages made with
CONFIG_RELOCATABLE=y put the relocs where the BSS is expected, and we
crash with unusual results such as:

lguest: unhandled trap 14 at 0xc0122ae1 (0xa9)

Relying on BSS being zero was merely laziness on my part, and
unfortunately, lguest doesn't go through the normal startup path (which
does this in asm).

[ARM] 4530/1: MXC: fix elf_hwcap compile breakage as in iop13xx

MXC needs the same change as IOP.  See [ARM] 4494/1
or commit 7dea1b20066cd30fb54da7e686b16b5e38b46b2d

An undefined reference to elf_hwcap prevents linkage, due
to changes made by f884b1cf578e079f01682514ae1ae64c74586602
and d1cbbd6b413510c6512f4f80ffd48db1a8dd554a

Removing processor.h removes the extern definition of
elf_hwcap, which fixes the link issue, but forgets cpu_relax().
So, instead, we'll call barrier() directly.

12 years ago[SCSI] aacraid: fix Sunrise Lake reset handling
Salyzyn, Mark [Fri, 27 Jul 2007 14:29:26 +0000]
[SCSI] aacraid: fix Sunrise Lake reset handling

The patch is *much* smaller than the description. I am attempting to
answer to those that want to understand an issue that was reported in
May this year.

If a Sunrise Lake based card that requires an alternate reset mechanism
is set up to ignore the commanded IOP_RESET it reports 0x00000010
(IOP_RESET ignored) instead of 0x3803000F (use alternate reset mechanism
to reset all cores), and thus the reset platform function decides to
switch to IOP_RESET_ALWAYS because the reset platform function
parameters indicate that we *need* to reset the card. IOP_RESET_ALWAYS
then responds with the 0x3803000F return code, but alas we treat this as
an error instead of using the alternate reset mechanism (put a 0x03 into
the register offset 0x38). The reset fails, but the fact that the
IOP_RESET_ALWAYS command was issued has put the card in a purposeful
shutdown state in preparation for the alternate hardware reset to be
applied. Yuck.

IOP_RESET is ignored in internal production cards, typically to ensure
that we catch all adapter lockup issues without the driver progressing
further, so this would not appear to be a field issue and thus this
patch was destined to be only in the internal Adaptec source tree.
IOP_RESET_ALWAYS is reserved for
kexec/kdump/FirmwareUpdate/AutomatedTestFrames so we did not function as
expected in any case. Also in the past we have had OEMs specifically
request that cards not be resetable after a BlinkLED/FirmwareAssert for
one reason or another and To head off the possibility that the Sunrise
Lake based cards would suffer a similar fate, we propose the enclosed
fix.

Yinghai Lu of SUN had a pre-production card with IOP_RESET disabled when
he reported an issue to the linux kernel list back in May regarding a
kexec problem resulting from this reset being ignore. His fix was to
update the Firmware to one that did not ignore the IOP_RESET. Previous
kernels did not attempt to reset the adapter and that is why it surfaced
as a regression in his hands.

The current list of aacraid based cards that use Sunrise Lake:

9005:0285:9005:02b5     Adaptec 5445
9005:0285:9005:02b6     Adaptec 5805

[S390] Fix IRQ tracing.

If a machine check is pending and the external or I/O interrupt handler
returns to userspace io_mcck_pending is going to call s390_handle_mcck.
Before this happens a call to TRACE_IRQS_ON was already made since we
know that we are going back to userspace and hence interrupts will be
enabled. So there was an indication that interrupts are enabled while
in reality they are still disabled.
s390_handle_mcck will do a local_irq_save/restore pair and confuse
lockdep which later complains about inconsistent irq tracing.
To solve this just call trace_hardirqs_off before calling
s390_handle_mcck and trace_hardirqs_on afterwards.

12 years agoFix "use after free" / "double free" bug in ati_create_gatt_pages / ati_free_gatt_pages
Jesper Juhl [Sat, 21 Jul 2007 15:39:11 +0000]
Fix "use after free" / "double free" bug in ati_create_gatt_pages / ati_free_gatt_pages

Hi,

Coverity spotted a "use after free" bug in
drivers/char/agp/ati-agp.c::ati_create_gatt_pages().

The same one that was in
  drivers/char/agp/amd-k7-agp.c::amd_create_gatt_pages()

The problem is this:
       If "entry = kzalloc(sizeof(struct ati_page_map), GFP_KERNEL);"
fails, then there's a loop in the function to free all entries
allocated so far and break out of the allocation loop. That in itself
is pretty sane, but then the (now freed) 'tables' is assigned to
ati_generic_private.gatt_pages and 'retval' is set to -ENOMEM which
causes ati_free_gatt_pages(); to be called at the end of the function.
The problem with this is that ati_free_gatt_pages() will then loop
'ati_generic_private.num_tables' times and try to free each entry in
tables[] - this is bad since tables has already been freed and
furthermore it will call kfree(tables) at the end - a double free.

This patch removes the freeing loop in ati_create_gatt_pages() and
instead relies entirely on the call to ati_free_gatt_pages() to free
everything we allocated in case of an error. It also sets
ati_generic_private.num_tables to the actual number of entries
allocated instead of just using the value passed in from the caller -
this ensures that ati_free_gatt_pages() will only attempt to free
stuff that was actually allocated.

Note: I'm in no way intimate with this code and I have no way to
actually test this patch (besides compile test it), so while I've
tried to be careful in reading the code and make sure the patch
does the right thing an ACK from someone who actually knows the
code in-depth would be very much appreciated.

Allow nodes to exist that only contain ZONE_MOVABLE

With the introduction of kernelcore=, a configurable zone is created on
request.  In some cases, this value will be small enough that some nodes
contain only ZONE_MOVABLE.  On some NUMA configurations when this occurs,
arch-independent zone-sizing will get the size of the memory holes within
the node incorrect.  The value of present_pages goes negative and the boot
fails.

This patch fixes the bug in the calculation of the size of the hole.  The
test case is to boot test a NUMA machine with a low value of kernelcore=
before and after the patch is applied.  While this bug exists in early
kernel it cannot be triggered in practice.

include/asm-:mips add missing edac h file

EDAC has a foundation to perform software memory scrubbing, but it requires a
per architecture (atomic_scrub) function for performing an atomic update
operation.  Under X86, this is done with a

lock:  add  [addr],0

in the file asm-x86/edac.h

This patch provides the MIPS arch with that atomic function, atomic_scrub() in

asm-mips/edac.h

This patch fixes sysfs exit code for the EDAC PCI device in a similiar manner
and the previous fixes for EDAC_MC and EDAC_DEVICE.

It removes the old (and incorrect) completion model and uses reference counts
on per instance kobjects and on the edac core module.

This pattern was applied to the edac_mc and edac_device code, but the EDAC PCI
code was missed.  In addition, this fixes a system hang after a low level

fix 'dynreloc miscount' link error on Powerpc

Nathan Lynch <ntl@pobox.com> reported:
2.6.23-rc1 breaks the build for 64-bit powerpc for me (using
maple_defconfig):

  LD      vmlinux.o

make: *** [vmlinux.o] Error 1

However, I see a possibly related binutils patch:
http://article.gmane.org/gmane.comp.gnu.binutils/33650

It was tracked down to be caused by the weak prototype
declaration in mm.h:
__attribute__((weak)) const char *arch_vma_name(struct vm_area_struct *vma);

But there is no need to make the declaration weak - only the definition
needs to be marked weak.  So drop the weak declaration.  And in the process
drop the duplicate definition in page.h for powerpc.

Note: the arch_vma_name fix for x86_64 needs to be applied first to avoid
breaking x86_64

12 years agofix inode_table test in ext234_check_descriptors
Eric Sandeen [Thu, 26 Jul 2007 17:41:11 +0000]
fix inode_table test in ext234_check_descriptors

ext[234]_check_descriptors sanity checks block group descriptor geometry at
mount time, testing whether the block bitmap, inode bitmap, and inode table
reside wholly within the blockgroup.  However, the inode table test is off
by one so that if the last block in the inode table resides on the last
block of the block group, the test incorrectly fails.  This is because it
tests the last block as (start + length) rather than (start + length - 1).

This can be seen by trying to mount a filesystem made such as:

 mkfs.ext2 -F -b 1024 -m 0 -g 256 -N 3744 fsfile 1024

which yields:

 EXT2-fs error (device loop0): ext2_check_descriptors: Inode table for group 0 not in group (block 101)!
 EXT2-fs: group descriptors corrupted!

There is a similar bug in e2fsprogs, patch already sent for that.

(I wonder if inside(), outside(), and/or in_range() should someday be
used in this and other tests throughout the ext filesystems...)

12 years agomemory unplug: migration by kernel
KAMEZAWA Hiroyuki [Thu, 26 Jul 2007 17:41:07 +0000]
memory unplug: migration by kernel

In usual, migrate_pages(page,,) is called with holding mm->sem by system call.
(mm here is a mm_struct which maps the migration target page.)
This semaphore helps avoiding some race conditions.

But, if we want to migrate a page by some kernel codes, we have to avoid
some races. This patch adds check code for following race condition.

1. A page which page->mapping==NULL can be target of migration. Then, we have
   to check page->mapping before calling try_to_unmap().

2. anon_vma can be freed while page is unmapped, but page->mapping remains as
   it was. We drop page->mapcount to be 0. Then we cannot trust page->mapping.
   So, use rcu_read_lock() to prevent anon_vma pointed by page->mapping from
   being freed during migration.

12 years agomake timerfd return a u64 and fix the __put_user
Davide Libenzi [Thu, 26 Jul 2007 17:41:07 +0000]
make timerfd return a u64 and fix the __put_user

Davi fixed a missing cast in the __put_user(), that was making timerfd
return a single byte instead of the full value.

Talking with Michael about the timerfd man page, we think it'd be better to
use a u64 for the returned value, to align it with the eventfd
implementation.

This is an ABI change.  The timerfd code is new in 2.6.22 and if we merge this
into 2.6.23 then we should also merge it into 2.6.22.x.  That will leave a few
early 2.6.22 kernels out in the wild which might misbehave when a future
timerfd-enabled glibc is run on them.

mtk says: The difference would be that read() will only return 4 bytes, while
the application will expect 8.  If the application is checking the size of
returned value, as it should, then it will be able to detect the problem (it
could even be sophisticated enough to know that if this is a 4-byte return,
then it is running on an old 2.6.22 kernel).  If the application is not
checking the return from read(), then its 8-byte buffer will not be filled --
the contents of the last 4 bytes will be undefined, so the u64 value as a
whole will be junk.
