commit f9279c968c257ee39b0d7bd2571a4d231a67bcc1 upstream.
The addition of the STARGET_REMOVE state had the side effect of
introducing a race condition that can cause a crash.
scsi_target_reap_ref_release() checks the starget->state to
see if it still in STARGET_CREATED, and if so, skips calling
transport_remove_device() and device_del(), because the starget->state
is only set to STARGET_RUNNING after scsi_target_add() has called
device_add() and transport_add_device().
However, if an rport loss occurs while a target is being scanned,
it can happen that scsi_remove_target() will be called while the
starget is still in the STARGET_CREATED state. In this case, the
starget->state will be set to STARGET_REMOVE, and as a result,
scsi_target_reap_ref_release() will take the wrong path. The end
result is a panic:

commit 440aeca4b9858248d8f16d724d9fa87a4f65fa33 upstream.
The functions igb_read_phy_reg_gs40g/igb_write_phy_reg_gs40g (which were
removed in 2a3cdea) explicitly selected the required page at every phy_reg
access. Currently, igb_get_phy_id_82575 relays on the fact that page 0 is
already selected. The assumption is not fulfilled for my Lex 3I380CW
motherboard with integrated dual i211 based gigabit ethernet. This leads to igb
initialization failure and network interfaces are not working:
igb: Intel(R) Gigabit Ethernet Network Driver - version 5.4.0-k
igb: Copyright (c) 2007-2014 Intel Corporation.
igb: probe of 0000:01:00.0 failed with error -2
igb: probe of 0000:02:00.0 failed with error -2
In order to fix it, we explicitly select page 0 before first access to phy
registers.

commit 4a4274bf2dbbd1c7a45be0c89a1687c9d2eef4a0 upstream.
In the stable linux-3.16 branch, I ran into a warning in the
wlcore driver:
drivers/net/wireless/ti/wlcore/spi.c: In function 'wl12xx_spi_raw_write':
drivers/net/wireless/ti/wlcore/spi.c:315:1: error: the frame size of 12848 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
Newer kernels no longer show the warning, but the bug is still there,
as the allocation is based on the CPU page size rather than the
actual capabilities of the hardware.
This replaces the PAGE_SIZE macro with the SZ_4K macro, i.e. 4096 bytes
per buffer.

commit 45dd39b974f6632222dd5cdcbea7358a077ab0b0 upstream.
The nci-device was never deregistered in the event that
fw-initialisation failed.
Fix this by moving the firmware initialisation before device
registration since the firmware work queue should be available before
registering.
Note that this depends on a recent fix that moved device-name
initialisation back to to nci_allocate_device() as the
firmware-workqueue name is now derived from the nfc-device name.

commit e5834ac22948169bbd7c45996d8d4905edd20f5e upstream.
Use the nfc- rather than phy-device in firmware-management code that
needs a valid struct device.
This specifically fixes a NULL-pointer dereference in
nfcmrvl_fw_dnld_init() during registration when the underlying tty is
one end of a Unix98 pty.
Note that the driver still uses the phy device for any debugging, which
is fine for now.

commit 0cbe40112f42cf5e008f9127f6cd5952ba3946c7 upstream.
This specifically fixes resource leaks in the registration error paths.
Device-managed resources is a bad fit for this driver as devices can be
registered from the n_nci line discipline. Firstly, a tty may not even
have a corresponding device (should it be part of a Unix98 pty)
something which would lead to a NULL-pointer dereference when
registering resources.
Secondly, if the tty has a class device, its lifetime exceeds that of
the line discipline, which means that resources would leak every time
the line discipline is closed (or if registration fails).
Currently, the devres interface was only being used to request a reset
gpio despite the fact that it was already explicitly freed in
nfcmrvl_nci_unregister_dev() (along with the private data), something
which also prevented the resource leak at close.
Note that the driver treats gpio number 0 as invalid despite it being
perfectly valid. This will be addressed in a follow-up patch.

commit 07246c115801c27652700e3679bb58661ef7ed65 upstream.
The bug was triggered when do suspend/resuming continuously
on Dell XPS L322X/0PJHXN version 9333 (2013) with kernel
4.12.0-041200rc4-generic. But can't reproduce on DELL
E5440 + AR9300 PCIE chips.
The warning is caused by accessing invalid pointer sc->rng_task.
sc->rng_task is not be cleared after kthread_stop(sc->rng_task)
be called in ath9k_rng_stop(). Because the kthread is stopped
before ath9k_rng_kthread() be scheduled.
So set sc->rng_task to null after kthread_stop(sc->rng_task) to
resolve this issue.

commit cf8ce1ea61b75712a154c93e40f2a5af2e4dd997 upstream.
One scenario that could lead to UAF is two threads writing
simultaneously to the "tx99" debug file. One of them would
set the "start" value to true and follow to ath9k_tx99_init().
Inside the function it would set the sc->tx99_state to true
after allocating sc->tx99skb. Then, the other thread would
execute write_file_tx99() and call ath9k_tx99_deinit().
sc->tx99_state would be freed. After that, the first thread
would continue inside ath9k_tx99_init() and call
r = ath9k_tx99_send(sc, sc->tx99_skb, &txctl);
that would make use of the freed sc->tx99_skb memory.

commit c592fafbdbb6b1279b76a54722d1465ca77e5bde upstream.
The thermal child device reuses the parent MFD-device device-tree node
when registering a thermal zone, but did not take a reference to the
node.
This leads to a reference imbalance, and potential use-after-free, when
the node reference is dropped by the platform-bus device destructor
(once for the child and later again for the parent).
Fix this by dropping any reference already held to a device-tree node
and getting a reference to the parent's node which will be balanced on
reprobe or on platform-device release, whichever comes first.
Note that simply clearing the of_node pointer on probe errors and on
driver unbind would not allow the use of device-managed resources as
specifically thermal_zone_of_sensor_unregister() claims that a valid
device-tree node pointer is needed during deregistration (even if it
currently does not seem to use it).

commit ea0212f40c6bc0594c8eff79266759e3ecd4bacc upstream.
The wakeirq infrastructure uses RCU to protect the list of wakeirqs. That
breaks the irq bus locking infrastructure, which is allows sleeping
functions to be called so interrupt controllers behind slow busses,
e.g. i2c, can be handled.
The wakeirq functions hold rcu_read_lock and call into irq functions, which
in case of interrupts using the irq bus locking will trigger a
might_sleep() splat.
Convert the wakeirq infrastructure to Sleepable RCU and unbreak it.

commit 7459e1d25ffefa2b1be799477fcc1f6c62f6cec7 upstream.
Driver does not properly handle the case when signals interrupt
wait_for_completion_interruptible():
-it does not check for return value
-completion structure is allocated on stack; in case a signal interrupts
the sleep, it will go out of scope, causing the worker thread
(caam_jr_dequeue) to fail when it accesses it
wait_for_completion_interruptible() is replaced with uninterruptable
wait_for_completion().
We choose to block all signals while waiting for I/O (device executing
the split key generation job descriptor) since the alternative - in
order to have a deterministic device state - would be to flush the job
ring (aborting *all* in-progress jobs).

commit 854b06f768794cd664886ec3ba3a5b1c58d42167 upstream.
Certain cipher modes like CTS expect the IV (req->info) of
ablkcipher_request (or equivalently req->iv of skcipher_request) to
contain the last ciphertext block when the {en,de}crypt operation is done.
This is currently not the case for the CAAM driver which in turn breaks
e.g. cts(cbc(aes)) when the CAAM driver is enabled.
This patch fixes the CAAM driver to properly set the IV after the
{en,de}crypt operation of ablkcipher finishes.
This issue was revealed by the changes in the SW CTS mode in commit
0605c41cc53ca ("crypto: cts - Convert to skcipher")

commit 03d2c5114c95797c0aa7d9f463348b171a274fd4 upstream.
An updated patch that also handles the additional key length requirements
for the AEAD algorithms.
The max keysize is not 96. For SHA384/512 it's 128, and for the AEAD
algorithms it's longer still. Extend the max keysize for the
AEAD size for AES256 + HMAC(SHA512).

commit 3360acdf839170b612f5b212539694c20e3f16d0 upstream.
Make sure to deregister and release the nvmem device and underlying
memory on registration errors.
Note that the private data must be freed using put_device() once the
struct device has been initialised.
Also note that there's a related reference leak in the deregistration
function as reported by Mika Westerberg which is being fixed separately.

commit 6987dc8a70976561d22450b5858fc9767788cc1c upstream.
Only read access is checked before this call.
Actually, at the moment this is not an issue, as every in-tree arch does
the same manual checks for VERIFY_READ vs VERIFY_WRITE, relying on the MMU
to tell them apart, but this wasn't the case in the past and may happen
again on some odd arch in the future.
If anyone cares about 3.7 and earlier, this is a security hole (untested)
on real 80386 CPUs.

[ Upstream commit c70d68150f71b84cea6997a53493e17bf18a54db ]
If we have more than 32 unicast MAC addresses assigned to an interface
we will read beyond the end of the address table in the driver when
adding filters. The next 256 entries store multicast addresses, so we
will end up attempting to insert duplicate filters, which is mostly
harmless. If we add more than 288 unicast addresses we will then read
past the multicast address table, which is likely to be more exciting.

commit 5ea59db8a375216e6c915c5586f556766673b5a7 upstream.
An earlier change to this function (3bdae810721b) fixed a leak in the
case of an unsuccessful call to brcmf_sdiod_buffrw(). However, the
glom_skb buffer, used for emulating a scattering read, is never used
or referenced after its contents are copied into the destination
buffers, and therefore always needs to be freed by the end of the
function.

only BRCMF_FIL_ACTION_FRAME_SIZE (1800) bytes long so this memcpy() can

commit f630c38ef0d785101363a8992bbd4f302180f86f upstream.
When destroying a VRF device we cleanup the slaves in its ndo_uninit()
function, but that causes packets to be switched (skb->dev == vrf being
destroyed) even though we're pass the point where the VRF should be
receiving any packets while it is being dismantled. This causes a BUG_ON
to trigger if we have raw sockets (trace below).
The reason is that the inetdev of the VRF has been destroyed but we're
still sending packets up the stack with it, so let's free the slaves in
the dellink callback as David Ahern suggested.
Note that this fix doesn't prevent packets from going up when the VRF
device is admin down.

The code that detects a failed soft reset of Octeon is comparing the wrong

commit db9d8b29d19d2801793e4419f4c6272bf8951c62 upstream.
The function, skb_complete_tx_timestamp(), used to allow passing in a
NULL pointer for the time stamps, but that was changed in commit
62bccb8cdb69051b95a55ab0c489e3cab261c8ef ("net-timestamp: Make the
clone operation stand-alone from phy timestamping"), and the existing
call sites, all of which are in the dp83640 driver, were fixed up.
Even though the kernel-doc was subsequently updated in commit
7a76a021cd5a292be875fbc616daf03eab1e6996 ("net-timestamp: Update
skb_complete_tx_timestamp comment"), still a bug fix from Manfred
Rudigier came into the driver using the old semantics. Probably
Manfred derived that patch from an older kernel version.
This fix should be applied to the stable trees as well.

commit b866203d872d5deeafcecd25ea429d6748b5bd56 upstream.
The commit ("net/phy: micrel: Add workaround for bad autoneg") fixes an
autoneg failure case by resetting the hardware. This turns off
intterupts. Things will work themselves out if the phy polls, as it will
figure out it's state during a poll. However if the phy uses only
intterupts, the phy will stall, since interrupts are off. This patch
fixes the issue by calling config_intr after resetting the phy.

commit 538d92912d3190a1dd809233a0d57277459f37b2 upstream.
The commit 90c311b0eeea ("xen-netfront: Fix Rx stall during network
stress and OOM") caused the refill timer to be triggerred almost on
all invocations of xennet_alloc_rx_buffers for certain workloads.
This reworks the fix by reverting to the old behaviour and taking into
consideration the skb allocation failure. Refill timer is now triggered
on insufficient requests or skb allocation failure.

commit 5a91206ff0d0548939f3e85a65fb76b400fb0e89 upstream.
When saa7134 module driving a Medion 7134 card is reloaded reads of this
card EEPROM (required for automatic detection of tuner model) will be
corrupted due to I2C gate in DVB-T demod being left closed.
This sometimes also happens on first saa7134 module load after a warm
reboot.
Fix this by opening this I2C gate before doing EEPROM read during i2c
initialization.

commit 42cfcafb91dabb0f9d9e08396c39824535948c67 upstream.
Changes in the SW cts (ciphertext stealing) code in
commit 0605c41cc53ca ("crypto: cts - Convert to skcipher")
revealed a problem in the CAAM driver:
when cts(cbc(aes)) is executed and cts runs in SW,
cbc(aes) is offloaded in CAAM; cts encrypts the last block
in atomic context and CAAM incorrectly decides to use GFP_KERNEL
for memory allocation.
Fix this by allowing GFP_KERNEL (sleeping) only when MAY_SLEEP flag is
set, i.e. remove MAY_BACKLOG flag.
We split the fix in two parts - first is sent to -stable, while the
second is not (since there is no known failure case).

commit a9332e9ad09c2644c99058fcf6ae2f355e93ce74 upstream.
There is a clean-up bug in the core comedi module initialization
functions, `comedi_init()`. If the `comedi_num_legacy_minors` module
parameter is non-zero (and valid), it creates that many "legacy" devices
and registers them in SysFS. A failure causes the function to clean up
and return an error. Unfortunately, it fails to destroy the "comedi"
class that was created earlier. Fix it by adding a call to
`class_destroy(comedi_class)` at the appropriate place in the clean-up
sequence.

commit d1bd4a792d3961a04e6154118816b00167aad91a upstream.
If a TPM2 loses power without a TPM2_Shutdown command being issued (a
"disorderly reboot"), it may lose some state that has yet to be
persisted to NVRam, and will increment the DA counter. After the DA
counter gets sufficiently large, the TPM will lock the user out.
NOTE: This only changes behavior on TPM2 devices. Since TPM1 uses sysfs,
and sysfs relies on implicit locking on chip->ops, it is not safe to
allow this code to run in TPM1, or to add sysfs support to TPM2, until
that locking is made explicit.
