The consequence is that assembling an array which contains a

GPIO: mvebu-gpio: Don't initialize the mask_cache
Due to the SMP nature of some of the chips, which have per CPU
registers, the driver does not use the generic irq_gc_mask_set_bit() &
irq_gc_mask_clr_bit() functions, which only support a single register.
The driver has its own implementation of these functions, which can
pick the correct register depending on the CPU being used. The
functions do however use the gc->mask_cache value.
The call to irq_setup_generic_chip() was passing
IRQ_GC_INIT_MASK_CACHE, which caused the gc->mask_cache to be
initialized to the contents of some random register. This resulted in
unexpected interrupts been delivered from random GPIO lines.

ath9k: Test for TID only in BlockAcks while checking tx status
The ath9k xmit functions for AMPDUs can send frames as non-aggregate in case
only one frame is currently available. The client will then answer using a
normal Ack instead of a BlockAck. This acknowledgement has no TID stored and
therefore the hardware is not able to provide us the corresponding TID.
The TID set by the hardware in the tx status descriptor has to be seen as
undefined and not as a valid TID value for normal acknowledgements. Doing
otherwise results in a massive amount of retransmissions and stalls of
connections.
Users may experience low bandwidth and complete connection stalls in
environments with transfers using multiple TIDs.

loop: Make explicit loop device destruction lazy
xfstests has always had random failures of tests due to loop devices
failing to be torn down and hence leaving filesytems that cannot be
unmounted. This causes test runs to immediately stop.
Over the past 6 or 7 years we've added hacks like explicit unmount
-d commands for loop mounts, losetup -d after unmount -d fails, etc,
but still the problems persist. Recently, the frequency of loop
related failures increased again to the point that xfstests 259 will
reliably fail with a stray loop device that was not torn down.
That is despite the fact the test is above as simple as it gets -
loop 5 or 6 times running mkfs.xfs with different paramters:
lofile=$(losetup -f)
losetup $lofile "$testfile"
"$MKFS_XFS_PROG" -b size=512 $lofile >/dev/null || echo "mkfs failed!"
sync
losetup -d $lofile
And losteup -d $lofile is failing with EBUSY on 1-3 of these loops
every time the test is run.
Turns out that blkid is running simultaneously with losetup -d, and
so it sees an elevated reference count and returns EBUSY. But why
is blkid running? It's obvious, isn't it? udev has decided to try
and find out what is on the block device as a result of a creation
notification. And it is racing with mkfs, so might still be scanning
the device when mkfs finishes and we try to tear it down.
So, make losetup -d force autoremove behaviour. That is, when the
last reference goes away, tear down the device. xfstests wants it
*gone*, not causing random teardown failures when we know that all
the operations the tests have specifically run on the device have
completed and are no longer referencing the loop device.

ext4: fix unjournaled inode bitmap modification
commit
119c0d4460b001e44b41dcf73dc6ee794b98bd31 changed
ext4_new_inode() such that the inode bitmap was being modified
outside a transaction, which could lead to corruption, and was
discovered when journal_checksum found a bad checksum in the
journal during log replay.
Nix ran into this when using the journal_async_commit mount
option, which enables journal checksumming. The ensuing
journal replay failures due to the bad checksums led to
filesystem corruption reported as the now infamous
"Apparent serious progressive ext4 data corruption bug"
[ Changed by tytso to only call ext4_journal_get_write_access() only
when we're fairly certain that we're going to allocate the inode. ]
I've tested this by mounting with journal_checksum and
running fsstress then dropping power; I've also tested by
hacking DM to create snapshots w/o first quiescing, which
allows me to test journal replay repeatedly w/o actually
power-cycling the box. Without the patch I hit a journal
checksum error every time. With this fix it survives
many iterations.

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.

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
1fd032ee10d2816c947f5d5b9abda95e728f0a8f
"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.

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.

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.

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.

other uses alone (so configfs will still work with ':' separated WWNs).

VFS: don't do protected {sym,hard}links by default
In commit
800179c9b8a1 ("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.
