Subject: [ 03/18] USB: option,qcserial: move Novatel Gobi1K IDs to qcserial

3.0-stable review patch. If anyone has any objections, please let me know.

------------------

From: Dan Williams <[email protected]>

commit a254810a86aaaac4ac6ba44fa934558b042a17a7 upstream.

These devices are all Gobi1K devices (according to the Windows INF
files) and should be handled by qcserial instead of option. Their
network port is handled by qmi_wwan.

3.0-stable review patch. If anyone has any objections, please let me know.

------------------

From: Al Viro <[email protected]>

commit 64cb927371cd2ec43758d8a094a003d27bc3d0dc upstream.

Both ext3 and ext4 htree_dirblock_to_tree() is just filling the
in-core rbtree for use by call_filldir(). All updates of ->f_pos are
done by the latter; bumping it here (on error) is obviously wrong - we
might very well have it nowhere near the block we'd found an error in.

Without this memory barrier, the file-storage thread may fail to

common->thread_wakeup_needed and old bh->state which are updated by
the callback functions.

Subject: [ 01/18] jbd2: fix theoretical race in jbd2__journal_restart

3.0-stable review patch. If anyone has any objections, please let me know.

------------------

From: Theodore Ts'o <[email protected]>

commit 39c04153fda8c32e85b51c96eb5511a326ad7609 upstream.

Once we decrement transaction->t_updates, if this is the last handle
holding the transaction from closing, and once we release the
t_handle_lock spinlock, it's possible for the transaction to commit
and be released. In practice with normal kernels, this probably won't
happen, since the commit happens in a separate kernel thread and it's
unlikely this could all happen within the space of a few CPU cycles.

On the other hand, with a real-time kernel, this could potentially
happen, so save the tid found in transaction->t_tid before we release
t_handle_lock. It would require an insane configuration, such as one
where the jbd2 thread was set to a very high real-time priority,
perhaps because a high priority real-time thread is trying to read or
write to a file system. But some people who use real-time kernels
have been known to do insane things, including controlling
laser-wielding industrial robots. :-)

3.0-stable review patch. If anyone has any objections, please let me know.

------------------

From: Jan Kara <[email protected]>

commit 8af8eecc1331dbf5e8c662022272cf667e213da5 upstream.

The arithmetics adding delalloc blocks to the number of used blocks in
ext4_getattr() can easily overflow on 32-bit archs as we first multiply
number of blocks by blocksize and then divide back by 512. Make the
arithmetics more clever and also use proper type (unsigned long long
instead of unsigned long).

From: Jed Davis <[email protected]>

commit c5f927a6f62196226915f12194c9d0df4e2210d7 upstream.

With this change, we no longer lose the innermost entry in the user-mode
part of the call chain. See also the x86 port, which includes the ip.

It's possible to partially work around this problem by post-processing
the data to use the PERF_SAMPLE_IP value, but this works only if the CPU
wasn't in the kernel when the sample was taken.

Subject: [ 11/18] ocfs2: xattr: fix inlined xattr reflink

3.0-stable review patch. If anyone has any objections, please let me know.

------------------

From: Junxiao Bi <[email protected]>

commit ef962df057aaafd714f5c22ba3de1be459571fdf upstream.

Inlined xattr shared free space of inode block with inlined data or data
extent record, so the size of the later two should be adjusted when
inlined xattr is enabled. See ocfs2_xattr_ibody_init(). But this isn't
done well when reflink. For inode with inlined data, its max inlined
data size is adjusted in ocfs2_duplicate_inline_data(), no problem. But
for inode with data extent record, its record count isn't adjusted. Fix
it, or data extent record and inlined xattr may overwrite each other,
then cause data corruption or xattr failure.

One panic caused by this bug in our test environment is the following:

From: Jan Kara <[email protected]>

commit a60697f411eb365fb09e639e6f183fe33d1eb796 upstream.

On 32-bit architectures with 32-bit sector_t computation of data offset
in ext4_xattr_fiemap() can overflow resulting in reporting bogus data

Subject: [ 08/18] genirq: Fix can_request_irq() for IRQs without an action

3.0-stable review patch. If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <[email protected]>

commit 2779db8d37d4b542d9ca2575f5f178dbeaca6c86 upstream.

Commit 02725e7471b8 ('genirq: Use irq_get/put functions'),
inadvertently changed can_request_irq() to return 0 for IRQs that have
no action. This causes pcibios_lookup_irq() to select only IRQs that
already have an action with IRQF_SHARED set, or to fail if there are
none. Change can_request_irq() to return 1 for IRQs that have no
action (if the first two conditions are met).

Subject: [ 07/18] xen/time: remove blocked time accounting from xen "clockchip"

3.0-stable review patch. If anyone has any objections, please let me know.

------------------

From: Laszlo Ersek <[email protected]>

commit 0b0c002c340e78173789f8afaa508070d838cf3d upstream.

... because the "clock_event_device framework" already accounts for idle
time through the "event_handler" function pointer in
xen_timer_interrupt().

The patch is intended as the completion of [1]. It should fix the double
idle times seen in PV guests' /proc/stat [2]. It should be orthogonal to
stolen time accounting (the removed code seems to be isolated).

The approach may be completely misguided.

[1] https://lkml.org/lkml/2011/10/6/10
[2] http://lists.xensource.com/archives/html/xen-devel/2010-08/msg01068.html

John took the time to retest this patch on top of v3.10 and reported:
"idle time is correctly incremented for pv and hvm for the normal
case, nohz=off and nohz=idle." so lets put this patch in.

Building a kernel with this kernel also works fine.

Sorry for the late review, but this patch is actually tagged for
stable kernels >= 3.9 ("Cc: 3.9+ <[email protected]>"). But it
is probably harmless and not worth the trouble of reverting them from
3.0 and 3.4.

I don't think it does any good without the preceding fix (commit
2fa97feb4406c546b52e35b6b6c50cb8f63425d2) which unfortunately requires
3.9. I don't know whether it will make things any worse.

These fixes should only go together.
