commit 2ca30331c156ca9e97643ad05dd8930b8fe78b01 upstream.
In the current code, if the user accidentally writes a bogus command to
this sysfs file, then we set the latency tolerance to an uninitialized
variable.

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.
Fixes: 4990d4fe327b (PM / Wakeirq: Add automated device wake IRQ handling)

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.

commit 866d7c1b0a3c70387646c4e455e727a58c5d465a upstream.

[ 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.

"len" so thats's max of 2280. However, the action_frame->data[] buffer is
only BRCMF_FIL_ACTION_FRAME_SIZE (1800) bytes long so this memcpy() can
overflow.

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.

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.

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 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.

commit da6c2addf66d7ff7d0b090d6267d4292f951e4e6 upstream.
To set the mux mode of a pin two bits must be set. Up to now this is
implemented using the following idiom:
writel(mask, reg + CLR);
writel(value, reg + SET);
. This however results in the mux mode being 0 between the two writes.
On my machine there is an IC's reset pin connected to LCD_D20. The
bootloader configures this pin as GPIO output-high (i.e. not holding the
IC in reset). When Linux reconfigures the pin to GPIO the short time
LCD_D20 is muxed as LCD_D20 instead of GPIO_1_20 is enough to confuse
the connected IC.
The same problem is present for the pin's drive strength setting which is
reset to low drive strength before using the right value.
So instead of relying on the hardware to modify the register setting
using two writes implement the bit toggling using read-modify-write.

commit 3908632fb829d73317c64c3d04f584b49f62e4ae upstream.
The R8A7791 PFC driver was apparently based on the preliminary revisions
of the user's manual, which omitted the DVC_MUTE signal altogether in
the PFC section. The modern manual has the signal described, so just add
the necassary data to the driver...

commit 58439280f84e6b39fd7d61f25ab30489c1aaf0a9 upstream.
PINMUX_IPSR_MSEL() macro invocation for the TX2 signal has apparently wrong
1st argument -- most probably a result of cut&paste programming...

commit 5f4c8cafe1148f8a91287072815df8f0b66f0e5c upstream.
All R8A7794 manuals I have here (0.50 and 1.10) agree that the PFC driver
has ATAG0# and ATAWR0# signals in IPSR12 swapped -- fix this.

commit 7036502783729c2aaf7a3c24c89087c58721430f upstream.
After commit 47c950d10202 ("pinctrl: cherryview: Do not add all
southwest and north GPIOs to IRQ domain") the driver does not add all
GPIOs to the irqdomain. The reason for that is that those GPIOs cannot
generate IRQs at all, only GPEs (General Purpose Events). This causes
Linux virtual IRQ numbering to change.
However, it seems some CYAN Chromebooks, including Acer Chromebook
hardcodes these Linux IRQ numbers in the ACPI tables of the machine.
Since the numbering is different now, the IRQ meant for keyboard does
not match the Linux virtual IRQ number anymore making the keyboard
non-functional.
Work this around by adding special quirk just for these machines where
we add back all GPIOs to the irqdomain. Rest of the Cherryview/Braswell
based machines will not be affected by the change.

commit d7402de48efae57bbb0072e53d3800c30de57ea5 upstream.
This patch adds the missing PINGROUP for GPIO70-99.
This fixes a crash that happens in pinctrl-msm, if any
of the GPIO70-99 are accessed.
