thinkpad-acpi: recognize latest V-Series using DMI_BIOS_VENDOR
commit a4f46bb9fa84642e356898ee44b670989622f8bb upstream.
In the latest V-series bios DMI_PRODUCT_VERSION does not contain
the string Lenovo or Thinkpad, but is set to the model number, this
causes the thinkpad_acpi module to fail to load. Recognize laptop
as Lenovo using DMI_BIOS_VENDOR instead, which is set to Lenovo.
Test on V490u

mac80211: close AP_VLAN interfaces before unregistering all
commit c8aa22db0112f640ac6631347f850879c621840b upstream.
Since Eric's commit efe117ab8 ("Speedup ieee80211_remove_interfaces")
there's a bug in mac80211 when it unregisters with AP_VLAN interfaces
up. If the AP_VLAN interface was registered after the AP it belongs
to (which is the typical case) and then we get into this code path,
unregister_netdevice_many() will crash because it isn't prepared to
deal with interfaces being closed in the middle of it. Exactly this
happens though, because we iterate the list, find the AP master this
AP_VLAN belongs to and dev_close() the dependent VLANs. After this,
unregister_netdevice_many() won't pick up the fact that the AP_VLAN
is already down and will do it again, causing a crash.

ALSA: usb-audio: avoid integer overflow in create_fixed_stream_quirk()
commit 8866f405efd4171f9d9c91901d2dd02f01bacb60 upstream.
A malicious USB device could feed in a large nr_rates value. This would
cause the subsequent call to kmemdup() to allocate a smaller buffer than
expected, leading to out-of-bounds access.
This patch validates the nr_rates value and reuses the limit introduced
in commit 4fa0e81b ("ALSA: usb-audio: fix possible hang and overflow
in parse_uac2_sample_rate_range()").

ALSA: usb-audio: fix possible hang and overflow in parse_uac2_sample_rate_range()
commit 4fa0e81b83503900be277e6273a79651b375e288 upstream.
A malicious USB device may feed in carefully crafted min/max/res values,
so that the inner loop in parse_uac2_sample_rate_range() could run for
a long time or even never terminate, e.g., given max = INT_MAX.
Also nr_rates could be a large integer, which causes an integer overflow
in the subsequent call to kmalloc() in parse_audio_format_rates_v2().
Thus, kmalloc() would allocate a smaller buffer than expected, leading
to a memory corruption.
To exploit the two vulnerabilities, an attacker needs physical access
to the machine to plug in a malicious USB device.
This patch makes two changes.
1) The type of "rate" is changed to unsigned int, so that the loop could
stop once "rate" is larger than INT_MAX.
2) Limit nr_rates to 1024.

jfs: fix a couple races
commit 73aaa22d5ffb2630456bac2f9a4ed9b81d0d7271 upstream.
This patch fixes races uncovered by xfstests testcase 068.
One race is the result of jfs_sync() trying to write a sync point to the
journal after it has been frozen (or possibly in the process). Since
freezing sync's the journal, there is no need to write a sync point so
we simply want to return.
The second involves jfs_write_inode() being called on a deleted inode.
It calls jfs_flush_journal which is held up by the jfs_commit thread
doing the final iput on the same deleted inode, which itself is
waiting for the I_SYNC flag to be cleared. jfs_write_inode need not
do anything when i_nlink is zero, which is the easy fix.

xen/events: Handle VIRQ_TIMER before any other hardirq in event loop.
commit bee980d9e9642e96351fa3ca9077b853ecf62f57 upstream.
This avoids any other hardirq handler seeing a very stale jiffies
value immediately after wakeup from a long idle period. The one
observable symptom of this was a USB keyboard, with software keyboard
repeat, which would always repeat a key immediately that it was
pressed. This is due to the key press waking the guest, the key
handler immediately runs, sees an old jiffies value, and then that
jiffies value significantly updated, before the key is unpressed.

libata: make ata_exec_internal_sg honor DMADIR
commit e771451c0a831d96a7c14b0ca8a8ec671d98567b upstream.
libata honors DMADIR for regular commands, but not for internal commands
used (among other) during device initialisation.
This makes SATA-host-to-PATA-device bridges based on Silicon Image SiL3611
(such as "Abit Serillel 2") end up disabled when used with an ATAPI device
after a few tries.
Log output of the bridge being hot-plugged with an ATAPI drive:

USB: io_ti: Fix NULL dereference in chase_port()
commit 1ee0a224bc9aad1de496c795f96bc6ba2c394811 upstream.
The tty is NULL when the port is hanging up.
chase_port() needs to check for this.
This patch is intended for stable series.
The behavior was observed and tested in Linux 3.2 and 3.7.1.
Johan Hovold submitted a more elaborate patch for the mainline kernel.

cifs: fix potential buffer overrun when composing a new options string
commit 166faf21bd14bc5c5295a44874bf7f3930c30b20 upstream.
Consider the case where we have a very short ip= string in the original
mount options, and when we chase a referral we end up with a very long
IPv6 address. Be sure to allow for that possibility when estimating the
size of the string to allocate.

commit 09fb8bd1a63b0f9f15e655c4fe8d047e5d2bf67a upstream.
Newer asics have variable numbers of crtcs. Use that
rather than the asic family to determine which crtcs
to check. This avoids checking non-existent crtcs or
missing crtcs on certain asics.

commit 7c3425123ddfdc5f48e7913ff59d908789712b18 upstream.
We should not use set_pmd_at to update pmd_t with pgtable_t pointer.
set_pmd_at is used to set pmd with huge pte entries and architectures
like ppc64, clear few flags from the pte when saving a new entry.
Without this change we observe bad pte errors like below on ppc64 with
THP enabled.

mm: mmu_notifier: re-fix freed page still mapped in secondary MMU
commit d34883d4e35c0a994e91dd847a82b4c9e0c31d83 upstream.
Commit 751efd8610d3 ("mmu_notifier_unregister NULL Pointer deref and
multiple ->release()") breaks the fix 3ad3d901bbcf ("mm: mmu_notifier:
fix freed page still mapped in secondary MMU").
Since hlist_for_each_entry_rcu() is changed now, we can not revert that
patch directly, so this patch reverts the commit and simply fix the bug
spotted by that patch
This bug spotted by commit 751efd8610d3 is:
There is a race condition between mmu_notifier_unregister() and
__mmu_notifier_release().
Assume two tasks, one calling mmu_notifier_unregister() as a result
of a filp_close() ->flush() callout (task A), and the other calling
mmu_notifier_release() from an mmput() (task B).
A B
t1 srcu_read_lock()
t2 if (!hlist_unhashed())
t3 srcu_read_unlock()
t4 srcu_read_lock()
t5 hlist_del_init_rcu()
t6 synchronize_srcu()
t7 srcu_read_unlock()
t8 hlist_del_rcu() <--- NULL pointer deref.
This can be fixed by using hlist_del_init_rcu instead of hlist_del_rcu.
The another issue spotted in the commit is "multiple ->release()
callouts", we needn't care it too much because it is really rare (e.g,
can not happen on kvm since mmu-notify is unregistered after
exit_mmap()) and the later call of multiple ->release should be fast
since all the pages have already been released by the first call.
Anyway, this issue should be fixed in a separate patch.
-stable suggestions: Any version that has commit 751efd8610d3 need to be
backported. I find the oldest version has this commit is 3.0-stable.

nilfs2: fix issue of nilfs_set_page_dirty() for page at EOF boundary
commit 136e8770cd5d1fe38b3c613100dd6dc4db6d4fa6 upstream.
nilfs2: fix issue of nilfs_set_page_dirty for page at EOF boundary
DESCRIPTION:
There are use-cases when NILFS2 file system (formatted with block size
lesser than 4 KB) can be remounted in RO mode because of encountering of
"broken bmap" issue.
The issue was reported by Anthony Doggett <Anthony2486@interfaces.org.uk>:
"The machine I've been trialling nilfs on is running Debian Testing,
Linux version 3.2.0-4-686-pae (debian-kernel@lists.debian.org) (gcc
version 4.6.3 (Debian 4.6.3-14) ) #1 SMP Debian 3.2.35-2), but I've
also reproduced it (identically) with Debian Unstable amd64 and Debian
Experimental (using the 3.8-trunk kernel). The problematic partitions
were formatted with "mkfs.nilfs2 -b 1024 -B 8192"."
SYMPTOMS:
(1) System log contains error messages likewise:
[63102.496756] nilfs_direct_assign: invalid pointer: 0
[63102.496786] NILFS error (device dm-17): nilfs_bmap_assign: broken bmap (inode number=28)
[63102.496798]
[63102.524403] Remounting filesystem read-only
(2) The NILFS2 file system is remounted in RO mode.
REPRODUSING PATH:
(1) Create volume group with name "unencrypted" by means of vgcreate utility.
(2) Run script (prepared by Anthony Doggett <Anthony2486@interfaces.org.uk>):
----------------[BEGIN SCRIPT]--------------------
VG=unencrypted
lvcreate --size 2G --name ntest $VG
mkfs.nilfs2 -b 1024 -B 8192 /dev/mapper/$VG-ntest
mkdir /var/tmp/n
mkdir /var/tmp/n/ntest
mount /dev/mapper/$VG-ntest /var/tmp/n/ntest
mkdir /var/tmp/n/ntest/thedir
cd /var/tmp/n/ntest/thedir
sleep 2
date
darcs init
sleep 2
dmesg|tail -n 5
date
darcs whatsnew || true
date
sleep 2
dmesg|tail -n 5
----------------[END SCRIPT]--------------------
REPRODUCIBILITY: 100%
INVESTIGATION:
As it was discovered, the issue takes place during segment
construction after executing such sequence of user-space operations:
open("_darcs/index", O_RDWR|O_CREAT|O_NOCTTY, 0666) = 7
fstat(7, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0
ftruncate(7, 60)
The error message "NILFS error (device dm-17): nilfs_bmap_assign: broken
bmap (inode number=28)" takes place because of trying to get block
number for third block of the file with logical offset #3072 bytes. As
it is possible to see from above output, the file has 60 bytes of the
whole size. So, it is enough one block (1 KB in size) allocation for
the whole file. Trying to operate with several blocks instead of one
takes place because of discovering several dirty buffers for this file
in nilfs_segctor_scan_file() method.
The root cause of this issue is in nilfs_set_page_dirty function which
is called just before writing to an mmapped page.
When nilfs_page_mkwrite function handles a page at EOF boundary, it
fills hole blocks only inside EOF through __block_page_mkwrite().
The __block_page_mkwrite() function calls set_page_dirty() after filling
hole blocks, thus nilfs_set_page_dirty function (=
a_ops->set_page_dirty) is called. However, the current implementation
of nilfs_set_page_dirty() wrongly marks all buffers dirty even for page
at EOF boundary.
As a result, buffers outside EOF are inconsistently marked dirty and
queued for write even though they are not mapped with nilfs_get_block
function.
FIX:
This modifies nilfs_set_page_dirty() not to mark hole blocks dirty.
Thanks to Vyacheslav Dubeyko for his effort on analysis and proposals
for this issue.

wait: fix false timeouts when using wait_event_timeout()
commit 4c663cfc523a88d97a8309b04a089c27dc57fd7e upstream.
Many callers of the wait_event_timeout() and
wait_event_interruptible_timeout() expect that the return value will be
positive if the specified condition becomes true before the timeout
elapses. However, at the moment this isn't guaranteed. If the wake-up
handler is delayed enough, the time remaining until timeout will be
calculated as 0 - and passed back as a return value - even if the
condition became true before the timeout has passed.
Fix this by returning at least 1 if the condition becomes true. This
semantic is in line with what wait_for_condition_timeout() does; see
commit bb10ed09 ("sched: fix wait_for_completion_timeout() spurious
failure under heavy load").
Daniel said "We have 3 instances of this bug in drm/i915. One case even
where we switch between the interruptible and not interruptible
wait_event_timeout variants, foolishly presuming they have the same
semantics. I very much like this."

klist: del waiter from klist_remove_waiters before wakeup waitting process
commit ac5a2962b02f57dea76d314ef2521a2170b28ab6 upstream.
There is a race between klist_remove and klist_release. klist_remove
uses a local var waiter saved on stack. When klist_release calls
wake_up_process(waiter->process) to wake up the waiter, waiter might run
immediately and reuse the stack. Then, klist_release calls
list_del(&waiter->list) to change previous
wait data and cause prior waiter thread corrupt.
The patch fixes it against kernel 3.9.

mm compaction: fix of improper cache flush in migration code
commit c2cc499c5bcf9040a738f49e8051b42078205748 upstream.
Page 'new' during MIGRATION can't be flushed with flush_cache_page().
Using flush_cache_page(vma, addr, pfn) is justified only if the page is
already placed in process page table, and that is done right after
flush_cache_page(). But without it the arch function has no knowledge
of process PTE and does nothing.
Besides that, flush_cache_page() flushes an application cache page, but
the kernel has a different page virtual address and dirtied it.
Replace it with flush_dcache_page(new) which is the proper usage.
The old page is flushed in try_to_unmap_one() before migration.
This bug takes place in Sead3 board with M14Kc MIPS CPU without cache
aliasing (but Harvard arch - separate I and D cache) in tight memory
environment (128MB) each 1-3days on SOAK test. It fails in cc1 during
kernel build (SIGILL, SIGBUS, SIGSEG) if CONFIG_COMPACTION is switched
ON.

goto out_unlock instead of out, because we need release buffer head, up

cifs: only set ops for inodes in I_NEW state
commit c2b93e0699723700f886ce17bb65ffd771195a6d upstream.
It's generally not safe to reset the inode ops once they've been set. In
the case where the inode was originally thought to be a directory and
then later found to be a DFS referral, this can lead to an oops when we
try to trigger an inode op on it after changing the ops to the blank
referral operations.

USB: UHCI: fix for suspend of virtual HP controller
commit 997ff893603c6455da4c5e26ba1d0f81adfecdfc upstream.
HP's virtual UHCI host controller takes a long time to suspend
(several hundred microseconds), even when no devices are attached.
This provokes a warning message from uhci-hcd in the auto-stop case.
To prevent this from happening, this patch adds a test to avoid
performing an auto-stop when the wait_for_hp quirk flag is set. The
controller will still suspend through the normal runtime PM mechanism.
And since that pathway includes a 1-ms delay, the slowness of the
virtual hardware won't matter.

TTY: Fix tty miss restart after we turn off flow-control

I meet emacs hang in start if I do the operation below:
1: echo 3 > /proc/sys/vm/drop_caches
2: emacs BigFile
3: Press CTRL-S follow 2 immediately
Then emacs hang on, CTRL-Q can't resume, the terminal
hang on, you can do nothing with this terminal except
close it.
The reason is before emacs takeover control the tty,
we use CTRL-S to XOFF it. Then when emacs takeover the
control, it may don't use the flow-control, so emacs hang.
This patch fix it.
This patch will fix a kind of strange tty relation hang problem,
I believe I meet it with vim in ssh, and also see below bug report:

The value of "offd" comes off the instance->rcv_buf[] and we used it as
the offset into an array. The problem is that we check the upper bound
but not for negative values.

ARM: plat-orion: Fix num_resources and id for ge10 and ge11
commit 2b8b2797142c7951e635c6eec5d1705ee9bc45c5 upstream.
When platform data were moved from arch/arm/mach-mv78xx0/common.c to
arch/arm/plat-orion/common.c with the commit "7e3819d ARM: orion:
Consolidate ethernet platform data", there were few typo made on
gigabit Ethernet interface ge10 and ge11. This commit writes back
their initial value, which allows to use this interfaces again.
