commit 730f23b66095a700e2f0786abda6bca011b31558 upstream.
In p8_aes_xts_init() we do a printk(KERN_INFO ...) to report the
fallback implementation we're using. However with a slow console this
can significantly affect the speed of crypto operations. So remove it.

commit 1411b5218adbcf1d45ddb260db5553c52e8d917c upstream.
In the vmx AES init routines we do a printk(KERN_INFO ...) to report
the fallback implementation we're using.
However with a slow console this can significantly affect the speed of
crypto operations. Using 'cryptsetup benchmark' the removal of the
printk() leads to a ~5x speedup for aes-cbc decryption.
So remove them.

commit c782a8c43e94ba6c09e9de2d69b5e3a5840ce61c upstream.
After issuing a request an endless loop was used to read the
completion state from memory which is asynchronously updated
by the ZIP coprocessor.
Add an upper bound to the retry attempts to prevent a CPU getting stuck
forever in case of an error. Additionally, add a read memory barrier
and a small delay between the reading attempts.

commit 37ff02acaa3d7be87ecb89f198a549ffd3ae2403 upstream.
Enabling virtual mapped kernel stacks breaks the thunderx_zip
driver. On compression or decompression the executing CPU hangs
in an endless loop. The reason for this is the usage of __pa
by the driver which does no longer work for an address that is
not part of the 1:1 mapping.
The zip driver allocates a result struct on the stack and needs
to tell the hardware the physical address within this struct
that is used to signal the completion of the request.
As the hardware gets the wrong address after the broken __pa
conversion it writes to an arbitrary address. The zip driver then
waits forever for the completion byte to contain a non-zero value.
Allocating the result struct from 1:1 mapped memory resolves this
bug.

commit 3a488aaec6f343b5dc6d94529847a840bbeaf009 upstream.
There are two IV-related issues:
(1) crypto API does not guarantee to provide an IV buffer that is DMAable,
thus it's incorrect to DMA map it
(2) for in-place decryption, since ciphertext is overwritten with
plaintext, updated IV (req->info) will contain the last block of plaintext
(instead of the last block of ciphertext)
While these two issues could be fixed separately, it's straightforward
to fix both in the same time - by using the {ablkcipher,aead}_edesc
extended descriptor to store the IV that will be fed to the crypto engine;
this allows for fixing (2) by saving req->src[last_block] in req->info
directly, i.e. without allocating yet another temporary buffer.
A side effect of the fix is that it's no longer possible to have the IV
contiguous with req->src or req->dst.
Code checking for this case is removed.

commit 4a7e625ce50412a7711efa0f2ef0b96ce3826759 upstream.
Commit 9b96fbacda34 ("serial: PL011: clear pending interrupts")
clears the RX and receive timeout interrupts on pl011 startup, to
avoid a screaming-interrupt scenario that can occur when the
firmware or bootloader leaves these interrupts asserted.
This has been noted as an issue when running Linux on qemu [1].
Unfortunately, the above fix seems to lead to potential
misbehaviour if the RX FIFO interrupt is asserted _non_ spuriously
on driver startup, if the RX FIFO is also already full to the
trigger level.
Clearing the RX FIFO interrupt does not change the FIFO fill level.
In this scenario, because the interrupt is now clear and because
the FIFO is already full to the trigger level, no new assertion of
the RX FIFO interrupt can occur unless the FIFO is drained back
below the trigger level. This never occurs because the pl011
driver is waiting for an RX FIFO interrupt to tell it that there is
something to read, and does not read the FIFO at all until that
interrupt occurs.
Thus, simply clearing "spurious" interrupts on startup may be
misguided, since there is no way to be sure that the interrupts are
truly spurious, and things can go wrong if they are not.
This patch instead clears the interrupt condition by draining the
RX FIFO during UART startup, after clearing any potentially
spurious interrupt. This should ensure that an interrupt will
definitely be asserted if the RX FIFO subsequently becomes
sufficiently full.
The drain is done at the point of enabling interrupts only. This
means that it will occur any time the UART is newly opened through
the tty layer. It will not apply to polled-mode use of the UART by
kgdboc: since that scenario cannot use interrupts by design, this
should not matter. kgdboc will interact badly with "normal" use of
the UART in any case: this patch makes no attempt to paper over
such issues.
This patch does not attempt to address the case where the RX FIFO
fills faster than it can be drained: that is a pathological
hardware design problem that is beyond the scope of the driver to
work around. As a failsafe, the number of poll iterations for
draining the FIFO is limited to twice the FIFO size. This will
ensure that the kernel at least boots even if it is impossible to
drain the FIFO for some reason.
[1] [Qemu-devel] [Qemu-arm] [PATCH] pl011: do not put into fifo
before enabled the interruption

commit b23220fe054e92f616b82450fae8cd3ab176cc60 upstream.
The balloon.page field is used for two different purposes if batching is
on or off. If batching is on, the field point to the page which is used
to communicate with with the hypervisor. If it is off, balloon.page
points to the page that is about to be (un)locked.
Unfortunately, this dual-purpose of the field introduced a bug: when the
balloon is popped (e.g., when the machine is reset or the balloon driver
is explicitly removed), the balloon driver frees, unconditionally, the
page that is held in balloon.page. As a result, if batching is
disabled, this leads to double freeing the last page that is sent to the
hypervisor.
The following error occurs during rmmod when kernel checkers are on, and
the balloon is not empty:

commit 13dc04d0e5fdc25c8f713ad23fdce51cf2bf96ba upstream.
I noticed that unused UARTs won't necessarily idle properly always
unless at least one byte tx transfer is done first.
After some debugging I narrowed down the problem to the scr register
dma configuration bits that need to be set before softreset for the
clocks to idle. Unless we do this, the module clkctrl idlest bits
may be set to 1 instead of 3 meaning the clock will never idle and
is blocking deeper idle states for the whole domain.
This might be related to the configuration done by the bootloader
or kexec booting where certain configurations cause the 8250 or
the clkctrl clock to jam in a way where setting of the scr bits
and reset is needed to clear it. I've tried diffing the 8250
registers for the various modes, but did not see anything specific.
So far I've only seen this on omap4 but I'm suspecting this might
also happen on the other clkctrl using SoCs considering they
already have a quirk enabled for UART_ERRATA_CLOCK_DISABLE.
Let's fix the issue by configuring scr before reset for basic dma
even if we don't use it. The scr register will be reset when we do
softreset few lines after, and we restore scr on resume. We should
do this for all the SoCs with UART_ERRATA_CLOCK_DISABLE quirk flag
set since the ones with UART_ERRATA_CLOCK_DISABLE are all based
using clkctrl similar to omap4.
Looks like both OMAP_UART_SCR_DMAMODE_1 | OMAP_UART_SCR_DMAMODE_CTL
bits are needed for the clkctrl to idle after a softreset.
And we need to add omap4 to also use the UART_ERRATA_CLOCK_DISABLE
for the related workaround to be enabled. This same compatible
value will also be used for omap5.

commit 9594b5be7ec110ed11acec58fa94f3f293668c85 upstream.
I was puzzled while looking at /proc/interrupts and random things showed
up between reboots. This occurred more often but I realised it later. The
"correct" output should be:
|38: 11861 atmel-aic5 2 Level ttyS0
but I saw sometimes
|38: 6426 atmel-aic5 2 Level tty1
and accounted it wrongly as correct. This is use after free and the
former example randomly got the "old" pointer which pointed to the same
content. With SLAB_FREELIST_RANDOM and HARDENED I even got
|38: 7067 atmel-aic5 2 Level E=Started User Manager for UID 0
or other nonsense.
As it turns out the tty, pointer that is accessed in atmel_startup(), is
freed() before atmel_shutdown(). It seems to happen quite often that the
tty for ttyS0 is allocated and freed while ->shutdown is not invoked. I
don't do anything special - just a systemd boot :)
Use dev_name(&pdev->dev) as the IRQ name for request_irq(). This exists
as long as the driver is loaded so no use-after-free here.

commit d63c16f8e1ab761775275adcf54f4bef7c330295 upstream.
Printk format "%pCr" will be removed soon, as clk_get_rate() must not be
called in atomic context.
Replace it by open-coding the operation. This is safe here, as the code
runs in task context.

commit bd6bce004d78b867ba0c6d3712f1c5b50398af9a upstream.
This patch fixes an issue that reconnection is possible to fail
because unexpected state handling happens by the irqs. To fix the issue,
the driver disables the controller's irqs when disconnected.

commit 0259068f63f23a665ded28647f2f9cdb6b20dc72 upstream.
This patch fixes an issue that this driver ignores errors other than
the non-existence of the device, f.e. a memory allocation failure
in devm_phy_get(). So, this patch replaces devm_phy_get() with
devm_phy_optional_get().

commit 4a014a7339f441b0851ce012f469c0fadac61c81 upstream.
When printer_write() calls usb_ep_queue(), a udc driver (e.g.
renesas_usbhs driver) may call usb_gadget_giveback_request() in
the udc .queue ops immediately. Then, printer_write() calls
list_add(&req->list, &dev->tx_reqs_active) wrongly. After that,
if we do unbind the printer driver, WARN_ON() happens in
printer_func_unbind() because the list entry is not removed.
So, this patch moves list_add(&req->list, &dev->tx_reqs_active)
calling before usb_ep_queue().

commit 05826ff135ee083d28c006fbde6e810f17437166 upstream.
The USB Type-C PHY in Intel WhiskeyCove PMIC has build-in
USB Type-C state machine which we were relying on to
configure the CC lines correctly. This patch removes that
dependency and configures the CC line according to commands
from the port manager (tcpm.c) in wcove_set_cc().
This fixes an issue where USB devices attached to the USB
Type-C port do not get enumerated. When acting as
source/host, the HW FSM sometimes fails to configure the PHY
correctly.

The proposed patch adds compatibility quirks. Because the drive requires two
quirks (one to work with UAS, and another to work with usb-storage), adding this
under unusual_devs.h and not just unusual_uas.h so kernels compiled without UAS
receive the quirk. With the patch, the drive works reliably on UAS and usb-
storage.
(tested on NEC Corporation uPD720200 USB 3.0 host controller).

commit a0d6ec88090d7b1b008429c44532a388e29bb1bd upstream.
pdev_nr and rhport can be controlled by user-space, hence leading to
a potential exploitation of the Spectre variant 1 vulnerability.
This issue was detected with the help of Smatch:
drivers/usb/usbip/vhci_sysfs.c:238 detach_store() warn: potential spectre issue 'vhcis'
drivers/usb/usbip/vhci_sysfs.c:328 attach_store() warn: potential spectre issue 'vhcis'
drivers/usb/usbip/vhci_sysfs.c:338 attach_store() warn: potential spectre issue 'vhci->vhci_hcd_ss->vdev'
drivers/usb/usbip/vhci_sysfs.c:340 attach_store() warn: potential spectre issue 'vhci->vhci_hcd_hs->vdev'
Fix this by sanitizing pdev_nr and rhport before using them to index
vhcis and vhci->vhci_hcd_ss->vdev respectively.
Notice that given that speculation windows are large, the policy is
to kill the speculation on the first load and not worry if it can be
completed with a dependent load/store [1].

commit dbafc28955fa6779dc23d1607a0fee5e509a278b upstream.
It's amazing that this driver ever worked, but now that x86 doesn't
allow USB data to be sent off of the stack, it really does not work at
all. Fix this up by properly allocating the data for the small
"commands" that get sent to the device off of the stack.
We do this for one command by having a whole urb just for ack messages,
as they can be submitted in interrupt context, so we can not use
usb_bulk_msg(). But the poweron command can sleep (and does), so use
usb_bulk_msg() for that transfer.

This is catching that a buffer was freed with an existing kernel mapping

DMA_BUF_SYNC_START without calling DMA_BUF_SYNC_END. Switch to a single

[ Upstream commit 5040cc990cbac98733df4d58fdeac5bbdab15b49 ]
In the Broadcom Cygnus SoC, the brcm tag needs to be inserted
in between the mac address and the ether type (should use
'DSA_PROTO_TAG_BRCM') for the packets sent to the internal
b53 switch.
Since the Cygnus was added with the BCM58XX device id and the
BCM58XX uses 'DSA_PROTO_TAG_BRCM_PREPEND', the data path is
broken, due to the incorrect brcm tag location.
Add a new b53 device id (BCM583XX) for Cygnus family to fix the
issue. Add the new device id to the BCM58XX family as Cygnus
is similar to the BCM58XX in most other functionalities.

Pull char/misc driver fixes from Greg KH:
"Here are four small bugfixes for some char/misc drivers. Well, really
three fixes and one fix for one of those fixes due to problems found
by 0-day.
This resolves some reported issues with the hwtracing drivers, and a
reported regression for the thunderbolt subsystem. All of these have
been in linux-next for a while now with no reported problems"

Pull rdma fixes from Jason Gunthorpe:
"Just three small last minute regressions that were found in the last
week. The Broadcom fix is a bit big for rc7, but since it is fixing
driver crash regressions that were merged via netdev into rc1, I am
sending it.
- bnxt netdev changes merged this cycle caused the bnxt RDMA driver
to crash under certain situations
- Arnd found (several, unfortunately) kconfig problems with the
patches adding INFINIBAND_ADDR_TRANS. Reverting this last part,
will fix it more fully outside -rc.
- Subtle change in error code for a uapi function caused breakage in
userspace. This was bug was subtly introduced cycle"
* tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma:
IB/core: Fix error code for invalid GID entry
IB: Revert "remove redundant INFINIBAND kconfig dependencies"

Bisection by Amadeusz Sławiński implicates this commit leading to bad
page state issues after VM shutdown, likely due to unbalanced page
references. The original commit was intended only as a performance
improvement, therefore revert for offline rework.
