Mikulas Patocka 5c1eabe685 percpu-rw-semaphores: use light/heavy barriers
This patch introduces new barrier pair light_mb() and heavy_mb() for
percpu rw semaphores.

This patch fixes a bug in percpu-rw-semaphores where a barrier was
missing in percpu_up_write.

This patch improves performance on the read path of
percpu-rw-semaphores: on non-x86 cpus, there was a smp_mb() in
percpu_up_read. This patch changes it to a compiler barrier and removes
the "#if defined(X86) ..." condition.

Jon Hunter c9c55d9211 gpio/omap: fix off-mode bug: clear debounce settings on free/reset
This change was originally titled "gpio/omap: fix off-mode bug: clear debounce
clock enable mask on free/reset". The title has been updated slightly to
reflect (what should be) the final fix.

When a GPIO is freed or shutdown, we need to ensure that any debounce settings
are cleared and if the GPIO is the only GPIO in the bank that is currently
using debounce, then disable the debounce clock as well to save power.

Currently, the debounce settings are not cleared on a GPIO free or shutdown and
so during a context restore on subsequent off-mode transition, the previous
debounce values are restored from the shadow copies (bank->context.debounce*)
leading to mismatch state between driver state and hardware state.

This was discovered when board code was doing

  gpio_request_one()
  gpio_set_debounce()
  gpio_free()

which was leaving the GPIO debounce settings in a confused state.  If that GPIO
bank is subsequently used with off-mode enabled, bogus state would be restored,
leaving GPIO debounce enabled which then prevented the CORE powerdomain from
transitioning.

To fix this, introduce a new function called _clear_gpio_debounce() to clear
any debounce settings when the GPIO is freed or shutdown. If this GPIO is the
last debounce-enabled GPIO in the bank, the debounce will also be cut.

Please note that we cannot use _gpio_dbck_disable() to disable the debounce
clock because this has been specifically created for the gpio suspend path
and is intended to shutdown the debounce clock while debounce is enabled.

Special thanks to Kevin Hilman for root causing the bug. This fix is a
collaborative effort with inputs from Kevin Hilman, Grazvydas Ignotas and
Santosh Shilimkar.

Testing:
- This has been unit tested on an OMAP3430 Beagle board, by requesting a gpio,
  enabling debounce and then freeing the gpio and checking the register
  contents, the saved register context and the debounce clock state.
- Kevin Hilman tested on 37xx/EVM board which configures GPIO debounce for the
  ads7846 touchscreen in its board file using the above sequence, and so was
  failing off-mode tests in dynamic idle. Verified that off-mode tests are
  passing with this patch.

Bernhard Kohl 1a1ff38c4c target: reintroduce some obsolete SCSI-2 commands
With kernel 3.6 some obsolete SCSI-2 commands including SEEK_10 have
have been removed by commit 1fd032ee10
"target: move code for CDB emulation".

There are still clients out there which use these old SCSI-2 commands.
This mainly happens when running VMs with legacy guest systems,
connected via SCSI command pass-through to iSCSI targets. Make them
happy and return status GOOD.

Many real SCSI disks or external iSCSI storage devices still support
these old commands. So let's make LIO backward compatible as well.

This patch adds support for the previously removed SEEK_10 and
additionally the SEEK_6 and REZERO_UNIT commands.

Nicholas Bellinger e13d5fef88 target: Fix double-free of se_cmd in target_complete_tmr_failure
Fabric drivers currently expect to internally release se_cmd in the event
of a TMR failure during target_submit_tmr(), which means the immediate call
to transport_generic_free_cmd() after TFO->queue_tm_rsp() from within
target_complete_tmr_failure() workqueue context is wrong.

This is done as some fabrics expect TMR operations to be acknowledged
before releasing the descriptor, so the assumption that core is releasing
se_cmd associated TMR memory is incorrect.  This fixes a OOPs where
transport_generic_free_cmd() was being called more than once.

This bug was originally observed with tcm_qla2xxx fabric ports.

Roland Dreier c8292d1da5 qla2xxx: Update target lookup session tables when a target session changes
It is possible for the target code to change the loop_id or s_id of a
target session in reaction to an FC fabric change.  However, the
session structures are stored in tables that are indexed by these two
keys, and if we just change the session structure but leave the
pointers to it in the old places in the table, havoc can ensue.  For
example, a new session might come along that should go in the old slot
in the table and overwrite the old session pointer.

To handle this, add a new tgt_ops->update_sess() method that also
updates the "by loop_id" and "by s_id" lookup tables when a session
changes, so that the keys where a session pointer is stored in these
tables always matches the keys in the session structure itself.

(nab: Drop unnecessary double inversion with FCF_CONF_COMP_SUPPORTED
      usage)

Roland Dreier c046aa0f0f tcm_qla2xxx: Format VPD page 83h SCSI name string according to SPC
My draft of SPC-4 says the following about the SCSI name string in
inquiry VPD page 83h:

    The SCSI NAME STRING field starts with either:

    a) the four UTF-8 characters 'eui.' concatenated with 16, 24, or
       32 hexadecimal digits (i.e., the UTF-8 characters 0 through 9
       and A through F) for an EUI-64 based identifier (see
       7.8.6.5). The first hexadecimal digit shall be the most
       significant four bits of the first byte (i.e., most significant
       byte) of the EUI-64 based identifier;
    b) the four UTF-8 characters 'naa.' concatenated with 16 or 32
       hexadecimal digits for an NAA identifier (see 7.8.6.6). The
       first hexadecimal digit shall be the most significant four bits
       of the first byte (i.e., most significant byte) of the NAA
       identifier; or
    c) the four UTF-8 characters 'iqn.' concatenated with an iSCSI
       Name for an iSCSI-name based identifier (see iSCSI).

However, the .tpg_get_wwn method for tcm_qla2xxx formats the WWN so
the SCSI name string looks like "52:4a:93:7d:24:5f:b2:12,t,0x0001".
This patch corrects the code so that VPD 83h gives a SPC-compliant
SCSI name string like "naa.524a937d245fb212,t,0x0001" while leavig
other uses alone (so configfs will still work with ':' separated WWNs).

Linus Torvalds 1d47091ac6 USB fixes for 3.7-rc3
Here are a bunch of USB fixes for the 3.7-rc tree.
 
 There's a lot of small USB serial driver fixes, and one larger one (the mos7840
 driver changes are mostly just moving code around to fix problems.)  Thanks to
 Johan Hovold for finding the problems and fixing them all up.
 
 Other than those, there is the usual new device ids, xhci bugfixes, and gadget
 driver fixes, nothing out of the ordinary.

Linus Torvalds 561ec64ae6 VFS: don't do protected {sym,hard}links by default
In commit 800179c9b8 ("This adds symlink and hardlink restrictions to
the Linux VFS"), the new link protections were enabled by default, in
the hope that no actual application would care, despite it being
technically against legacy UNIX (and documented POSIX) behavior.

However, it does turn out to break some applications.  It's rare, and
it's unfortunate, but it's unacceptable to break existing systems, so
we'll have to default to legacy behavior.

In particular, it has broken the way AFD distributes files, see

  http://www.dwd.de/AFD/

along with some legacy scripts.

Distributions can end up setting this at initrd time or in system
scripts: if you have security problems due to link attacks during your
early boot sequence, you have bigger problems than some kernel sysctl
setting. Do:

	echo 1 > /proc/sys/fs/protected_symlinks
	echo 1 > /proc/sys/fs/protected_hardlinks

to re-enable the link protections.

Alternatively, we may at some point introduce a kernel config option
that sets these kinds of "more secure but not traditional" behavioural
options automatically.

Dan Williams f8295ec22c qmi_wwan/cdc_ether: move Novatel 551 and E362 to qmi_wwan
These devices provide QMI and ethernet functionality via a standard CDC
ethernet descriptor.  But when driven by cdc_ether, the QMI
functionality is unavailable because only cdc_ether can claim the USB
interface.  Thus blacklist the devices in cdc_ether and add their IDs to
qmi_wwan, which enables both QMI and ethernet simultaneously.

Hemant Kumar 39707c2a3b net: usb: Fix memory leak on Tx data path
Driver anchors the tx urbs and defers the urb submission if
a transmit request comes when the interface is suspended.
Anchoring urb increments the urb reference count. These
deferred urbs are later accessed by calling usb_get_from_anchor()
for submission during interface resume. usb_get_from_anchor()
unanchors the urb but urb reference count remains same.
This causes the urb reference count to remain non-zero
after usb_free_urb() gets called and urb never gets freed.
Hence call usb_put_urb() after anchoring the urb to properly
balance the reference count for these deferred urbs. Also,
unanchor these deferred urbs during disconnect, to free them
up.

Jack Morgenstein 7208ca3007 net/mlx4_en: Fix double-release-range in tx-rings
The QP range is reserved as a single block. However, when freeing the
en resources, the tx-ring QPs are released both in mlx4_en_destroy_tx_ring
(one at a time) and in mlx4_en_free_resources (as a block release).

Fix by eliminating the one-at-a-time release in mlx4_en_destroy_tx_ring.

Tilman Schmidt c6fdd8e5d0 bas_gigaset: fix pre_reset handling
The delayed work function int_in_work() may call usb_reset_device()
and thus, indirectly, the driver's pre_reset method. Trying to
cancel the work synchronously in that situation would deadlock.
Fix by avoiding cancel_work_sync() in the pre_reset method.

If the reset was NOT initiated by int_in_work() this might cause
int_in_work() to run after the post_reset method, with urb_int_in
already resubmitted, so handle that case gracefully.
