PCI hotplug: shpchp: don't blindly claim non-AMD 0x7450 device IDs
commit
4cac2eb158c6da0c761689345c6cc5df788a6292 upstream.
Previously we claimed device ID 0x7450, regardless of the vendor, which is
clearly wrong. Now we'll claim that device ID only for AMD.
I suspect this was just a typo in the original code, but it's possible this
change will break shpchp on non-7450 AMD bridges. If so, we'll have to fix
them as we find them.

CB tuning is needed to handle potential process variations that might
cause clock jitter for certain PLL settings. However, we were setting
it incorrectly since we were using the wrong M value as a check (M1 when
we needed to use the whole M value). Fix it up, making my HDMI

eCryptfs: Extend array bounds for all filename chars
commit
0f751e641a71157aa584c2a2e22fda52b52b8a56 upstream.
From mhalcrow's original commit message:
Characters with ASCII values greater than the size of
filename_rev_map[] are valid filename characters.
ecryptfs_decode_from_filename() will access kernel memory beyond
that array, and ecryptfs_parse_tag_70_packet() will then decrypt
those characters. The attacker, using the FNEK of the crafted file,
can then re-encrypt the characters to reveal the kernel memory past
the end of the filename_rev_map[] array. I expect low security
impact since this array is statically allocated in the text area,
and the amount of memory past the array that is accessible is
limited by the largest possible ASCII filename character.
This patch solves the issue reported by mhalcrow but with an
implementation suggested by Linus to simply extend the length of
filename_rev_map[] to 256. Characters greater than 0x7A are mapped to
0x00, which is how invalid characters less than 0x7A were previously
being handled.

Fixes a possible memory corruption when the link is larger than
MAXPATHLEN and XFS_DEBUG is not enabled. This also remove the

Updated to address concerns raised by Ben Hutchings about the loose

potentially negative pathlen value:
- Changed type of "pathlen" to be xfs_fsize_t, to match that of
ip->i_d.di_size
- Added checking for a negative pathlen to the too-long pathlen
test, and generalized the message that gets reported in that case
to reflect the change
As a result, if a negative pathlen were encountered, this function
would return EFSCORRUPTED (and would fail an assertion for a debug
build)--just as would a too-long pathlen.

The code to flush buffers in the umount code is a bit iffy: we first

would get flushed out when doing the synchronous superblock write in
xfs_unmountfs_writesb, but we skip that one if the filesystem has

xfs: dont serialise direct IO reads on page cache
commit
0c38a2512df272b14ef4238b476a2e4f70da1479 upstream.
There is no need to grab the i_mutex of the IO lock in exclusive
mode if we don't need to invalidate the page cache. Taking these
locks on every direct IO effective serialises them as taking the IO
lock in exclusive mode has to wait for all shared holders to drop
the lock. That only happens when IO is complete, so effective it
prevents dispatch of concurrent direct IO reads to the same inode.
Fix this by taking the IO lock shared to check the page cache state,
and only then drop it and take the IO lock exclusively if there is
work to be done. Hence for the normal direct IO case, no exclusive
locking will occur.

During umount we do not add a dirty inode to the lru and wait for it to
become clean first, but force writeback of data and metadata with
I_WILL_FREE set. Currently there is no way for XFS to detect that the
inode has been redirtied for metadata operations, as we skip the
mark_inode_dirty call during teardown. Fix this by setting i_update_core
nanually in that case, so that the inode gets flushed during inode reclaim.
Alternatively we could enable calling mark_inode_dirty for inodes in
I_WILL_FREE state, and let the VFS dirty tracking handle this. I decided
against this as we will get better I/O patterns from reclaim compared to
the synchronous writeout in write_inode_now, and always marking the inode
dirty in some way from xfs_mark_inode_dirty is a better safetly net in
either case.

USB: EHCI: fix HUB TT scheduling issue with iso transfer
commit
811c926c538f7e8d3c08b630dd5844efd7e000f6 upstream.
The current TT scheduling doesn't allow to play and then record on a
full-speed device connected to a high speed hub.
The IN iso stream can only start on the first uframe (0-2 for a 165 us)
because of CSPLIT transactions.
For the OUT iso stream there no such restriction. uframe 0-5 are possible.
The idea of this patch is that the first uframe are precious (for IN TT iso
stream) and we should allocate the last uframes first if possible.
For that we reverse the order of uframe allocation (last uframe first).
Here an example :
hid interrupt stream
----------------------------------------------------------------------
uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
----------------------------------------------------------------------
max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 |
----------------------------------------------------------------------
used usecs on a frame | 13 | 0 | 0 | 0 | 0 | 0 | 0 | 0 |
----------------------------------------------------------------------
iso OUT stream
----------------------------------------------------------------------
uframe | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
----------------------------------------------------------------------
max_tt_usecs | 125 | 125 | 125 | 125 | 125 | 125 | 30 | 0 |
----------------------------------------------------------------------
used usecs on a frame | 13 | 125 | 39 | 0 | 0 | 0 | 0 | 0 |
----------------------------------------------------------------------
There no place for iso IN stream (uframe 0-2 are used) and we got "cannot
submit datapipe for urb 0, error -28: not enough bandwidth" error.
With the patch this become.
iso OUT stream
----------------------------------------------------------------------

usb-storage: Accept 8020i-protocol commands longer than 12 bytes
commit
2f640bf4c94324aeaa1b6385c10aab8c5ad1e1cf upstream.
The 8020i protocol (also 8070i and QIC-157) uses 12-byte commands;
shorter commands must be padded. Simon Detheridge reports that his
3-TB USB disk drive claims to use the 8020i protocol (which is
normally meant for ATAPI devices like CD drives), and because of its
large size, the disk drive requires the use of 16-byte commands.
However the usb_stor_pad12_command() routine in usb-storage always
sets the command length to 12, making the drive impossible to use.
Since the SFF-8020i specification allows for 16-byte commands in
future extensions, we may as well accept them. This patch (as1490)
changes usb_stor_pad12_command() to leave commands larger than 12
bytes alone rather than truncating them.

USB: Fix Corruption issue in USB ftdi driver ftdi_sio.c
commit
b1ffb4c851f185e9051ba837c16d9b84ef688d26 upstream.
Fix for ftdi_set_termios() glitching output
ftdi_set_termios() is constantly setting the baud rate, data bits and parity
unnecessarily on every call, . When called while characters are being
transmitted can cause the FTDI chip to corrupt the serial port bit stream
output by stalling the output half a bit during the output of a character.
Simple fix by skipping this setting if the baud rate/data bits/parity are
unchanged.

USB: workaround for bug in old version of GCC
commit
97ff22ee3b4cb3a334f7385e269773141aed702f upstream.
This patch (as1491) works around a bug in GCC-3.4.6, which is still
supposed to be supported. The number of microseconds in the udelay()
call in quirk_usb_disable_ehci() is fixed at 100, but the compiler
doesn't understand this and generates a link-time error. So we
replace the otherwise unused variable "delta" with a simple constant
100. This same pattern is already used in other delay loops in that
source file.

USB: cdc-acm: Fix disconnect() vs close() race
commit
5dc2470c602da8851907ec18942cd876c3b4ecc1 upstream.
There's a race between the USB disconnect handler and the TTY close
handler which may cause the acm object to be freed while it's still
being used. This may lead to things like
http://article.gmane.org/gmane.linux.usb.general/54250
and
https://lkml.org/lkml/2011/5/29/64
This is the simplest fix I could come up with. Holding on to open_mutex
while closing the TTY device prevents acm_disconnect() from freeing the
acm object between acm->port.count drops to 0 and the TTY side of the
cleanups are finalized.

USB: XHCI: resume root hubs when the controller resumes
commit
f69e3120df82391a0ee8118e0a156239a06b2afb upstream.
This patch (as1494) fixes a problem in xhci-hcd's resume routine.
When the controller is runtime-resumed, this can only mean that one of
the two root hubs has made a wakeup request and therefore needs to be
resumed as well. Rather than try to determine which root hub requires
attention (which might be difficult in the case where a new
non-SuperSpeed device has been plugged in), the patch simply resumes
both root hubs.
Without this change, there is a race: The controller might be put back
to sleep before it can activate its IRQ line, and the wakeup condition
might never get handled.
The patch also simplifies the logic in xhci_resume a little, combining
some repeated flag settings into a single pair of statements.

Basically what is happening is in xhci_stop_endpoint_command_watchdog()
the xhci->lock is grabbed with just spin_lock. What lockdep deduces is
that if an interrupt occurred while in this function it would deadlock
with xhci_irq because that function also grabs the xhci->lock.
Fixing it is trivial by using spin_lock_irqsave instead.
This should be queued to stable kernels as far back as 2.6.33.

usb, xhci: Clear warm reset change event during init
commit
79c3dd8150fd5236d95766a9e662e3e932b462c9 upstream.
I noticed on my Panther Point system that I wasn't getting hotplug events
for my usb3.0 disk on a usb3 port. I tracked it down to the fact that the
system had the warm reset change bit still set. This seemed to block future
events from being received, including a hotplug event.
Clearing this bit during initialization allowed the hotplug event to be
received and the disk to be recognized correctly.
This patch should be backported to kernels as old as 2.6.39.

[ 223.701992] xhci_hcd 0000:03:00.0: Setup ERROR: address device command for slot 1.
The xHCI spec says that both flags must be set to one for the Address
Device command. When the device is first enumerated,
xhci_setup_addressable_virt_dev() does set those flags. However, when
the device is addressed after it has been reset in the configured state,
xhci_setup_addressable_virt_dev() is not called, and
xhci_copy_ep0_dequeue_into_input_ctx() is called instead. That function
relies on the flags being set up by previous commands, which apparently
isn't a good assumption.
Move the setting of the flags into the common parent function.
This should be queued for stable kernels as old as 2.6.35, since that
was the first introduction of xhci_copy_ep0_dequeue_into_input_ctx.

nfs: when attempting to open a directory, fall back on normal lookup (try #5)
commit
1788ea6e3b2a58cf4fb00206e362d9caff8d86a7 upstream.
commit
d953126 changed how nfs_atomic_lookup handles an -EISDIR return
from an OPEN call. Prior to that patch, that caused the client to fall
back to doing a normal lookup. When that patch went in, the code began
returning that error to userspace. The d_revalidate codepath however
never had the corresponding change, so it was still possible to end up
with a NULL ctx->state pointer after that.
That patch caused a regression. When we attempt to open a directory that
does not have a cached dentry, that open now errors out with EISDIR. If
you attempt the same open with a cached dentry, it will succeed.
Fix this by reverting the change in nfs_atomic_lookup and allowing
attempts to open directories to fall back to a normal lookup
Also, add a NFSv4-specific f_ops->open routine that just returns
-ENOTDIR. This should never be called if things are working properly,
but if it ever is, then the dprintk may help in debugging.
To facilitate this, a new file_operations field is also added to the
nfs_rpc_ops struct.

TTY: ldisc, wait for ldisc infinitely in hangup
commit
0c73c08ec73dbe080b9ec56696ee21d32754d918 upstream.
For /dev/console case, we do not kill all ldisc users. It's due to
redirected_tty_write test in __tty_hangup. In that case there still
might be a process waiting e.g. in n_tty_read for input.
We wait for such processes to disappear. The problem is that we use a
timeout. After this timeout, we continue closing the ldisc and start
freeing tty resources. It obviously leads to crashes when the other
process is woken.
So to fix this, we wait infinitely before reiniting the ldisc. (The
tiocsetd remains untouched -- times out after 5s.)
This is nicely reproducible with this run from shell:
exec 0<>/dev/console 1<>/dev/console 2<>/dev/console
and stopping a getty like:
systemctl stop serial-getty@ttyS0.service
The crash proper may be produced only under load or with constified
timing the same as for
92f6fa09b.

commit
c2a3e84f950e7ddba1f3914b005861d46ae60359 upstream.
Reading from the DCC grabs a character from the buffer and
clears the status bit. Since this is a context-changing
operation, instructions following the character read that rely on
the status bit being accurate need to be synchronized with an
ISB.
In this case, the status bit check needs to execute after the
character read otherwise we run the risk of reading the character
and checking the status bit before the read can clear the status
bit in the first place. When this happens, the user will see the
same character they typed twice, instead of once.
Add an ISB after the read and the write, so that the status check
is synchronized with the read/write operations.

pch_uart: Fix DMA resource leak issue
commit
90f04c2926cfb5bf74533b0a7766bc896f6a0c0e upstream.
Changing UART mode PIO->DMA->PIO->DMA like below, pch_uart driver can't get
DMA channel resource.
setserial /dev/ttyPCH0 ^low_latency
setserial /dev/ttyPCH0 low_latency
CAUSE:
Changing mode using setserial command, ".startup" function which gets DMA
channel is called before ".verify_port" function which sets
dma-flag(use_dma/use_dma_flag) as 1.
PIO->DMA
.startup: Since dma-flag is 0, DMA channel is not requested.
.verify_port: dma-flag is set as 1.
.shutdown: N/A
DMA->PIO
.startup: Since dma-flag is 1, DMA channel is requested.
.verify_port: dma-flag is set as 0.
.shutdown: Since dma-flag is 0, DMA channel is not released.
This means DMA channel resource leak occurs.
Next time, this driver can't get DMA channel resource forever.
MODIFICATION:
Currently, when release DMA channel resource, this driver checks dma-flag.
However, this specification occurs the above issue.
This driver must check whether dma_request_channel is executed or not.
The values are saved in private data variable "chan_tx/chan_tx".
These variables mean if the value is NULL, DMA channel is not requested,
if not NULL, DMA channel is requested.
This patch fixes the issue.

I ran out this issue using an auto-suspend supported USB devices, like

after the usb controller has been shut down, and the usb runtime suspend
routine will try to suspend its roothub(controller), it will access

ip6_tunnel: copy parms.name after register_netdevice
commit
731abb9cb27aef6013ce60808a04e04a545f3f4e upstream.
Commit
1c5cae815d removed an explicit call to dev_alloc_name in ip6_tnl_create
because register_netdevice will now create a valid name. This works for the
net_device itself.
However the tunnel keeps a copy of the name in the parms structure for the
ip6_tnl associated with the tunnel. parms.name is set by copying the net_device
name in ip6_tnl_dev_init_gen. That function is called from ip6_tnl_dev_init in
ip6_tnl_create, but it is done before register_netdevice is called so the name
is set to a bogus value in the parms.name structure.
This shows up if you do a simple tunnel add, followed by a tunnel show:
[root@localhost ~]# ip -6 tunnel add remote fec0::100 local fec0::200
[root@localhost ~]# ip -6 tunnel show
ip6tnl0: ipv6/ipv6 remote :: local :: encaplimit 0 hoplimit 0 tclass 0x00 flowlabel 0x00000 (flowinfo 0x00000000)

Fix this by moving the strcpy out of ip6_tnl_dev_init_gen, and calling it after
register_netdevice has successfully returned.

Commit
4d9d88d1 by Scott James Remnant <keybuk@google.com> added
the .uevent() callback for the regulatory device used during
the platform device registration. The change was done to account
for queuing up udev change requests through udevadm triggers.
The change also meant that upon regulatory core exit we will now
send a uevent() but the uevent() callback, reg_device_uevent(),
also accessed last_request. Right before commiting device suicide
we free'd last_request but never set it to NULL so
platform_device_unregister() would lead to bogus kernel paging
request. Fix this and also simply supress uevents right before
we commit suicide as they are pointless.
This fix is required for kernels >= v2.6.39
$ git describe --contains

Since the NL80211_ATTR_HT_CAPABILITY attribute is

potentially lead to reading after the buffer.

When receiving failed PLCP frames is enabled, there

not assuming the rate pointer is always valid. It's
still always valid for frames that have good PLCP

rt2x00: Fix sleep-while-atomic bug in powersaving code.
commit
ed66ba472a742cd8df37d7072804b2111cdb1014 upstream.
The generic powersaving code that determines after reception of a frame
whether the device should go back to sleep or whether is could stay
awake was calling rt2x00lib_config directly from RX tasklet context.
On a number of the devices this call can actually sleep, due to having
to confirm that the sleeping commands have been executed successfully.
Fix this by moving the call to rt2x00lib_config to a workqueue call.

This also happens to fix DP displays re-lighting on resume. I'm quite

aacraid: controller hangs if kernel uses non-default ASPM policy
commit
cf16123c9c8e346ed1dd171295a678d77648d7f8 upstream.
Aacraid controller can hang on some nodes if kernel uses non-default
(powersave) ASPM policy. Controller hangs shortly after successful load and
hardware detection. Scsi error handler detects this hang and tries to restart
hardware but it does not help.
Initially it was noticed on RHEL6-based openVZ kernel after backporting
aacraid driver from mainline (RHEL6 kernel with original driver works well)
http://bugzilla.openvz.org/show_bug.cgi?id=2043
This issue happens because default ASPM policy was changed in Red Hat
kernels. Therefore guys from Red Hat have noticed this problem long time ago:
on Fedora 12
https://bugzilla.redhat.com/show_bug.cgi?id=540478
on Fedora 14
https://bugzilla.redhat.com/show_bug.cgi?id=679385
In RHEL6 kernel this issue was fixed, ASPM was disabled in aacraid driver. In
kernel changelog I've found that seems it was done by Matthew Garrett: -
[scsi] aacraid: Disable ASPM by default (Matthew Garrett) [599735]
However seems this patch was not submitted to mainline. I've reproduced this
issue on vanilla 3.1.0 kernel booted with "pcie_aspm.policy=powersave" option,
So I believe it makes sense to do it now.

genirq: Fix irqfixup, irqpoll regression
commit
c75d720fca8a91ce99196d33adea383621027bf2 upstream.
commit
d05c65fff0 ("genirq: spurious: Run only one poller at a time")
introduced a regression, leaving the boot options 'irqfixup' and
'irqpoll' non-functional. The patch placed tests in each function, to
exit if the function is already running. The test in 'misrouted_irq'
exited when it should have proceeded, effectively disabling
'misrouted_irq' and 'poll_spurious_irqs'.
The check for an already running poller needs to be "!= 1" not "== 1"
as "1" is the value when the first poller starts running.

backing-dev: ensure wakeup_timer is deleted
commit
7a401a972df8e184b3d1a3fc958c0a4ddee8d312 upstream.
bdi_prune_sb() in bdi_unregister() attempts to removes the bdi links
from all super_blocks and then del_timer_sync() the writeback timer.
However, this can race with __mark_inode_dirty(), leading to
bdi_wakeup_thread_delayed() rearming the writeback timer on the bdi
we're unregistering, after we've called del_timer_sync().
This can end up with the bdi being freed with an active timer inside it,
as in the case of the following dump after the removal of an SD card.
Fix this by redoing the del_timer_sync() in bdi_destory().

powerpc: Copy down exception vectors after feature fixups
commit

kdump fails because we try to execute an HV only instruction. Feature
fixups are being applied after we copy the exception vectors down to 0
so they miss out on any updates.
We have always had this issue but it only became critical in v3.0
when we added CFAR support (breaks POWER5) and v3.1 when we added
POWERNV (breaks everyone).

powerpc/ps3: Fix lost SMP IPIs

Fixes the PS3 bootup hang introduced in 3.0-rc1 by:
commit
317f394160e9beb97d19a84c39b7e5eb3d7815a
sched: Move the second half of ttwu() to the remote cpu
Move the PS3's LV1 EOI call lv1_end_of_interrupt_ext() from ps3_chip_eoi()
to ps3_get_irq() for IPI messages.
If lv1_send_event_locally() is called between a previous call to
lv1_send_event_locally() and the coresponding call to
lv1_end_of_interrupt_ext() the second event will not be delivered to the
target cpu.
The PS3's SMP IPIs are implemented using lv1_send_event_locally(), so if two
IPI messages of the same type are sent to the same target in a relatively
short period of time the second IPI event can become lost when
lv1_end_of_interrupt_ext() is called from ps3_chip_eoi().

SFI tables reside in RAM and should not be modified once they are
written. Current code went to set pentry->irq to zero which causes
subsequent reads to fail with invalid SFI table checksum. This will
break kexec as the second kernel fails to validate SFI tables.
To fix this we use temporary variable for irq number.

ALSA: usb-audio - Fix the missing volume quirks at delayed init
commit
dcaaf9f2c16b56f8bb316881fcd3f15c18fc71e7 upstream.
In the recent usb-audio driver, the initialization of volume ranges
may be delayed when the device doesn't respond well at the probing time.
But the volume quirks for certain devices are applied only in
mixer_ctl_feature_info() thus only at the very first probe and will be
missing when the volume range is initialized later.
This patch moves the volume quirk code to be always called from the
volume-range extraction (get_min_max()), so that the quirks are properly
applied in the later init time.

virtio-pci: fix use after free
commit
72103bd1285211440621f2c46f4fce377584de54 upstream.
Commit
31a3ddda166cda86d2b5111e09ba4bda5239fae6 introduced
a use after free in virtio-pci. The main issue is
that the release method signals removal of the virtio device,
while remove signals removal of the pci device.
For example, on driver removal or hot-unplug,
virtio_pci_release_dev is called before virtio_pci_remove.
We then might get a crash as virtio_pci_remove tries to use the
device freed by virtio_pci_release_dev.
We allocate/free all resources together with the
pci device, so we can leave the release method empty.

ALSA: hda - Don't add elements of other codecs to vmaster slave
commit
aeb4b88ec0a948efce8e3a23a8f964d3560a7308 upstream.
When a virtual mater control is created, the driver looks for slave
elements from the assigned card instance. But this may include the
elements of other codecs when multiple codecs are on the same HD-audio
bus. This works at the first time, but it'll give Oops when it's once
freed and re-created via reconfig sysfs.
This patch changes the element-look-up strategy to limit only to the
mixer elements of the same codec.

hid/apple: modern macbook airs use the standard apple function key translations

This removes the use of the special "macbookair_fn_keys" keyboard
translation table for the MacBookAir4,x models (ie the 2011 refresh).
They use the standard apple_fn_keys[] translation. Apparently only the
old MacBook Air's need a different translation table.
This mirrors the change that commit

MacbookAir 4,1 mappings") did for the WELLSPRING6A ones, but does it for
the WELLSPRING6 model used on the MacBookAir4,2.
