commit 23584c1ed3e15a6f4bfab8dc5a88d94ab929ee12 upstream.
The Power Fault Detected bit in the Slot Status register differs from
all other hotplug events in that it is sticky: It can only be cleared
after turning off slot power. Per PCIe r5.0, sec. 6.7.1.8:
If a power controller detects a main power fault on the hot-plug slot,
it must automatically set its internal main power fault latch [...].
The main power fault latch is cleared when software turns off power to
the hot-plug slot.
The stickiness used to cause interrupt storms and infinite loops which
were fixed in 2009 by commits 5651c48cfafe ("PCI pciehp: fix power fault
interrupt storm problem") and 99f0169c17f3 ("PCI: pciehp: enable
software notification on empty slots").
Unfortunately in 2020 the infinite loop issue was inadvertently
reintroduced by commit 8edf5332c393 ("PCI: pciehp: Fix MSI interrupt
race"): The hardirq handler pciehp_isr() clears the PFD bit until
pciehp's power_fault_detected flag is set. That happens in the IRQ
thread pciehp_ist(), which never learns of the event because the hardirq
handler is stuck in an infinite loop. Fix by setting the
power_fault_detected flag already in the hardirq handler.

[ Upstream commit 2f61353cd2f789a4229b6f5c1c24a40a613357bb ]
Since some interrupt states may be cleared by hardware, the driver
may receive an empty interrupt. Currently, the VF driver directly
disables the vector0 interrupt in this case. As a result, the VF
is unavailable. Therefore, the vector0 interrupt should be enabled
in this case.

[ Upstream commit 9ff5549b1d1d3c3a9d71220d44bd246586160f1d ]
In the WIN10 version of the Synthetic Video protocol with Hyper-V,
Hyper-V reports a list of supported resolutions as part of the protocol
negotiation. The driver calculates the maximum width and height from
the list of resolutions, and uses those maximums to validate any screen
resolution specified in the video= option on the kernel boot line.
This method of validation is incorrect. For example, the list of
supported resolutions could contain 1600x1200 and 1920x1080, both of
which fit in an 8 Mbyte frame buffer. But calculating the max width
and height yields 1920 and 1200, and 1920x1200 resolution does not fit
in an 8 Mbyte frame buffer. Unfortunately, this resolution is accepted,
causing a kernel fault when the driver accesses memory outside the
frame buffer.
Instead, validate the specified screen resolution by calculating
its size, and comparing against the frame buffer size. Delete the
code for calculating the max width and height from the list of
resolutions, since these max values have no use. Also add the
frame buffer size to the info message to aid in understanding why
a resolution might be rejected.

[ Upstream commit 48079e7fdd0269d66b1d7d66ae88bd03162464ad ]
ibmvnic_tasklet() continuously spins waiting for responses to all
capability requests. It does this to avoid encountering an error
during initialization of the vnic. However if there is a bug in the
VIOS and we do not receive a response to one or more queries the
tasklet ends up spinning continuously leading to hard lock ups.
If we fail to receive a message from the VIOS it is reasonable to
timeout the login attempt rather than spin indefinitely in the tasklet.

[ Upstream commit 151b6a5c06b678687f64f2d9a99fd04d5cd32b72 ]
We use ->running_cap_crqs to determine when the ibmvnic_tasklet() should
send out the next protocol message type. i.e when we get back responses
to all our QUERY_CAPABILITY CRQs we send out REQUEST_CAPABILITY crqs.
Similiary, when we get responses to all the REQUEST_CAPABILITY crqs, we
send out the QUERY_IP_OFFLOAD CRQ.
We currently increment ->running_cap_crqs as we send out each CRQ and
have the ibmvnic_tasklet() send out the next message type, when this
running_cap_crqs count drops to 0.
This assumes that all the CRQs of the current type were sent out before
the count drops to 0. However it is possible that we send out say 6 CRQs,
get preempted and receive all the 6 responses before we send out the
remaining CRQs. This can result in ->running_cap_crqs count dropping to
zero before all messages of the current type were sent and we end up
sending the next protocol message too early.
Instead initialize the ->running_cap_crqs upfront so the tasklet will
only send the next protocol message after all responses are received.
Use the cap_reqs local variable to also detect any discrepancy (either
now or in future) in the number of capability requests we actually send.
Currently only send_query_cap() is affected by this behavior (of sending
next message early) since it is called from the worker thread (during
reset) and from application thread (during ->ndo_open()) and they can be
preempted. send_request_cap() is only called from the tasklet which
processes CRQ responses sequentially, is not be affected. But to
maintain the existing symmtery with send_query_capability() we update
send_request_capability() also.

PF forwards its VF messages to AF and corresponding

checks the error codes in replies and sends invalid

changes that such that PF simply forwards AF replies
so that VF can handle error codes.

[ Upstream commit d15c7e875d44367005370e6a82e8f3a382a04f9b ]
A problem was encountered with the Bel-Fuse 1GBT-SFP05 SFP module (which
is a 1 Gbps copper module operating in SGMII mode with an internal
BCM54616S PHY device) using the Xilinx AXI Ethernet MAC core, where the
module would work properly on the initial insertion or boot of the
device, but after the device was rebooted, the link would either only
come up at 100 Mbps speeds or go up and down erratically.
I found no meaningful changes in the PHY configuration registers between
the working and non-working boots, but the status registers seemed to
have a lot of error indications set on the SERDES side of the device on
the non-working boot. I suspect the problem is that whatever happens on
the SGMII link when the device is rebooted and the FPGA logic gets
reloaded ends up putting the module's onboard PHY into a bad state.
Since commit 6e2d85ec0559 ("net: phy: Stop with excessive soft reset")
the genphy_soft_reset call is not made automatically by the PHY core
unless the callback is explicitly specified in the driver structure. For
most of these Broadcom devices, there is probably a hardware reset that
gets asserted to reset the PHY during boot, however for SFP modules
(where the BCM54616S is commonly found) no such reset line exists, so if
the board keeps the SFP cage powered up across a reboot, it will end up
with no reset occurring during reboots.
Hook up the genphy_soft_reset callback for BCM54616S to ensure that a
PHY reset is performed before the device is initialized. This appears to
fix the issue with erratic operation after a reboot with this SFP
module.

[ Upstream commit a66c5ed539277b9f2363bbace0dba88b85b36c26 ]
According to its datasheet, G781 supports a maximum conversion rate value
of 8 (62.5 ms). However, chips labeled G781 and G780 were found to only
support a maximum conversion rate value of 7 (125 ms). On the other side,
chips labeled G781-1 and G784 were found to support a conversion rate value
of 8. There is no known means to distinguish G780 from G781 or G784; all
chips report the same manufacturer ID and chip revision.
Setting the conversion rate register value to 8 on chips not supporting
it causes unexpected behavior since the real conversion rate is set to 0
(16 seconds) if a value of 8 is written into the conversion rate register.
Limit the conversion rate register value to 7 for all G78x chips to avoid
the problem.

commit 7a534ae89e34e9b51acb5a63dd0f88308178b46a upstream.
struct rpmsg_eptdev contains a struct cdev. The current code frees
the rpmsg_eptdev struct in rpmsg_eptdev_destroy(), but the cdev is
a managed object, therefore its release is not predictable and the
rpmsg_eptdev could be freed before the cdev is entirely released.
The cdev_device_add/del() API was created to address this issue
(see commit '233ed09d7fda ("chardev: add helper function to register
char devs with a struct device")'), use it instead of cdev add/del().

This was caused by PF queue pile fragmentation due to
flow director VSI queue being placed right after main VSI.
Because of this main VSI was not able to resize its
queue allocation for XDP resulting in no queues allocated
for main VSI when XDP was turned on.
Fix this by always allocating last queue in PF queue pile
for a flow director VSI.

commit d701658a50a471591094b3eb3961b4926cc8f104 upstream.
Before this patch VF interface vanished when
maximum queue number was exceeded. Driver tried
to add next queues even if there was not enough
space. PF sent incorrect number of queues to
the VF when there were not enough of them.
Add an additional condition introduced to check
available space in 'qp_pile' before proceeding.
This condition makes it impossible to add queues
if they number is greater than the number resulting
from available space.
Also add the search for free space in PF queue
pair piles.
Without this patch VF interfaces are not seen
when available space for queues has been
exceeded and following logs appears permanently
in dmesg:
"Unable to get VF config (-32)".
"VF 62 failed opcode 3, retval: -5"
"Unable to get VF config due to PF error condition, not retrying"

commit 825911492eb15bf8bb7fb94bc0c0421fe7a6327d upstream.
CCGx clears Bit 0:Device Interrupt in the INTR_REG
if CCGx is reset successfully. However, there might
be a chance that other bits in INTR_REG are not
cleared due to internal data queued in PPM. This case
misleads the driver that CCGx reset failed.
The commit checks bit 0 in INTR_REG and ignores other
bits. The ucsi driver would reset PPM later.

commit 90b8aa9f5b09edae6928c0561f933fec9f7a9987 upstream.
With some chargers, vbus might momentarily raise above VSAFE5V and fall
back to 0V before tcpm gets to read port->tcpc->get_vbus. This will
will report a VBUS off event causing TCPM to transition to
SNK_UNATTACHED where it should be waiting in either SNK_ATTACH_WAIT
or SNK_DEBOUNCED state. This patch makes TCPM avoid vbus off events
while in SNK_ATTACH_WAIT or SNK_DEBOUNCED state.

commit 26fbe9772b8c459687930511444ce443011f86bf upstream.
The syzbot fuzzer has identified a bug in which processes hang waiting
for usb_kill_urb() to return. It turns out the issue is not unlinking
the URB; that works just fine. Rather, the problem arises when the
wakeup notification that the URB has completed is not received.
The reason is memory-access ordering on SMP systems. In outline form,
usb_kill_urb() and __usb_hcd_giveback_urb() operating concurrently on
different CPUs perform the following actions:
CPU 0 CPU 1
---------------------------- ---------------------------------
usb_kill_urb(): __usb_hcd_giveback_urb():
... ...
atomic_inc(&urb->reject); atomic_dec(&urb->use_count);
... ...
wait_event(usb_kill_urb_queue,
atomic_read(&urb->use_count) == 0);
if (atomic_read(&urb->reject))
wake_up(&usb_kill_urb_queue);
Confining your attention to urb->reject and urb->use_count, you can
see that the overall pattern of accesses on CPU 0 is:
write urb->reject, then read urb->use_count;
whereas the overall pattern of accesses on CPU 1 is:
write urb->use_count, then read urb->reject.
This pattern is referred to in memory-model circles as SB (for "Store
Buffering"), and it is well known that without suitable enforcement of
the desired order of accesses -- in the form of memory barriers -- it
is entirely possible for one or both CPUs to execute their reads ahead
of their writes. The end result will be that sometimes CPU 0 sees the
old un-decremented value of urb->use_count while CPU 1 sees the old
un-incremented value of urb->reject. Consequently CPU 0 ends up on
the wait queue and never gets woken up, leading to the observed hang
in usb_kill_urb().
The same pattern of accesses occurs in usb_poison_urb() and the
failure pathway of usb_hcd_submit_urb().
The problem is fixed by adding suitable memory barriers. To provide
proper memory-access ordering in the SB pattern, a full barrier is
required on both CPUs. The atomic_inc() and atomic_dec() accesses
themselves don't provide any memory ordering, but since they are
present, we can use the optimized smp_mb__after_atomic() memory
barrier in the various routines to obtain the desired effect.
This patch adds the necessary memory barriers.

commit 2e3dd4a6246945bf84ea6f478365d116e661554c upstream.
Commit 7495af930835 ("ARM: multi_v7_defconfig: Enable drivers for
DragonBoard 410c") enables the CONFIG_PHY_QCOM_USB_HS for the ARM
multi_v7_defconfig. Enabling this Kconfig is causing the kernel to crash
on the Tegra20 Ventana platform in the ulpi_match() function.
The Qualcomm USB HS PHY driver that is enabled by CONFIG_PHY_QCOM_USB_HS,
registers a ulpi_driver but this driver does not provide an 'id_table',
so when ulpi_match() is called on the Tegra20 Ventana platform, it
crashes when attempting to deference the id_table pointer which is not
valid. The Qualcomm USB HS PHY driver uses device-tree for matching the
ULPI driver with the device and so fix this crash by using device-tree
for matching if the id_table is not valid.

__device_suspend+0x108/0x3c0
The basic flow:
1. run time suspend call xhci_suspend, xhci parent devices gate the clock.
2. echo mem >/sys/power/state, system _device_suspend call xhci_suspend
3. xhci_suspend call xhci_disable_hub_port_wake, which access register,
but clock already gated by run time suspend.
This problem was hidden by power domain driver, which call run time resume before it.
But the below commit remove it and make this issue happen.
commit c1df456d0f06e ("PM: domains: Don't runtime resume devices at genpd_prepare()")
This patch call run time resume before suspend to make sure clock is on
before access register.

commit 5b67b315037250a61861119683e7fcb509deea25 upstream.
Two people have reported (and mentioned numerous other reports on the
web) that VIA's VL817 USB-SATA bridge does not work with the uas
driver. Typical log messages are:
[ 3606.232149] sd 14:0:0:0: [sdg] tag#2 uas_zap_pending 0 uas-tag 1 inflight: CMD
[ 3606.232154] sd 14:0:0:0: [sdg] tag#2 CDB: Write(16) 8a 00 00 00 00 00 18 0c c9 80 00 00 00 80 00 00
[ 3606.306257] usb 4-4.4: reset SuperSpeed Plus Gen 2x1 USB device number 11 using xhci_hcd
[ 3606.328584] scsi host14: uas_eh_device_reset_handler success
Surprisingly, the devices do seem to work okay for some other people.
The cause of the differing behaviors is not known.
In the hope of getting the devices to work for the most users, even at
the possible cost of degraded performance for some, this patch adds an
unusual_devs entry for the VL817 to block it from binding to the uas
driver by default. Users will be able to override this entry by means
of a module parameter, if they want.
