commit 7db0e0c8190a086ef92ce5bb960836cde49540aa upstream.
According to ZBC and SPC specifications, the unit of ALLOCATION LENGTH
field of REPORT ZONES command is byte. However, current scsi_debug
implementation handles it as number of zones to calculate buffer size to
report zones. When the ALLOCATION LENGTH has a large number, this results
in too large buffer size and causes memory allocation failure. Fix the
failure by handling ALLOCATION LENGTH as byte unit.

commit a74c313aca266fab0d1d1a72becbb8b7b5286b6e upstream.
Maxime points out that the polling code in mpc_i2c_isr should use the
_atomic API because it is called in an irq context and that the
behaviour of the MCF bit is that it is 1 when the byte transfer is
complete. All of this means the original code was effectively a
udelay(100).
Fix this by using readb_poll_timeout_atomic() and removing the negation
of the break condition.

commit a880b28a71e39013e357fd3adccd1d8a31bc69a8 upstream.
wake_up_poll() uses nr_exclusive=1, so it's not guaranteed to wake up
all exclusive waiters. Yet, POLLFREE *must* wake up all waiters. epoll
and aio poll are fortunately not affected by this, but it's very
fragile. Thus, the new function wake_up_pollfree() has been introduced.
Convert binder to use wake_up_pollfree().

commit b19926d4f3a660a8b76e5d989ffd1168e619a5c4 upstream.
dma_fence_chain_find_seqno only ever returns the top fence in the
chain or an unsignalled fence. Hence if we request a seqno that
is already signalled it returns a NULL fence. Some callers are
not prepared to handle this, like the syncobj transfer functions
for example.
This behavior is "new" with timeline syncobj and it looks like
not all callers were updated. To fix this behavior make sure
that a successful drm_sync_find_fence always returns a non-NULL
fence.
v2: Move the fix to drm_syncobj_find_fence from the transfer
functions.

commit 9a61f813fcc8d56d85fcf9ca6119cf2b5ac91dd5 upstream.
The function mux_get_parent() uses qcom_find_src_index() to find the
parent clock index, which is incorrect: qcom_find_src_index() uses src
enum for the lookup, while mux_get_parent() should use cfg field (which
corresponds to the register value). Add qcom_find_cfg_index() function
doing this kind of lookup and use it for mux parent lookup.

commit a2ca752055edd39be38b887e264d3de7ca2bc1bb upstream.
Before commit 86585c61972f ("hwmon: (pwm-fan) stop using legacy
PWM functions and some cleanups") pwm_apply_state() was called
unconditionally in pwm_fan_probe(). In this commit this direct
call was replaced by a call to __set_pwm(ct, MAX_PWM) which
however is a noop if ctx->pwm_value already matches the value to
set.
After probe the fan is supposed to run at full speed, and the
internal driver state suggests it does, but this isn't asserted
and depending on bootloader and pwm low-level driver, the fan
might just be off.
So drop setting pwm_value to MAX_PWM to ensure the check in
__set_pwm doesn't make it exit early and the fan goes on as
intended.

commit a50e659b2a1be14784e80f8492aab177e67c53a2 upstream.
The registration of XDP queue information is incorrect because the
RX queue id we use is invalid. When port->id == 0 it appears to works
as expected yet it's no longer the case when port->id != 0.
The problem arised while using a recent kernel version on the
MACCHIATOBin. This board has several ports:
* eth0 and eth1 are 10Gbps interfaces ; both ports has port->id == 0;
* eth2 is a 1Gbps interface with port->id != 0.
Code from xdp-tutorial (more specifically advanced03-AF_XDP) was used
to test packet capture and injection on all these interfaces. The XDP
kernel was simplified to:
SEC("xdp_sock")
int xdp_sock_prog(struct xdp_md *ctx)
{
int index = ctx->rx_queue_index;
/* A set entry here means that the correspnding queue_id
* has an active AF_XDP socket bound to it. */
if (bpf_map_lookup_elem(&xsks_map, &index))
return bpf_redirect_map(&xsks_map, index, 0);
return XDP_PASS;
}
Starting the program using:
./af_xdp_user -d DEV
Gives the following result:
* eth0 : ok
* eth1 : ok
* eth2 : no capture, no injection
Investigating the issue shows that XDP rx queues for eth2 are wrong:
XDP expects their id to be in the range [0..3] but we found them to be
in the range [32..35].
Trying to force rx queue ids using:
./af_xdp_user -d eth2 -Q 32
fails as expected (we shall not have more than 4 queues).
When we register the XDP rx queue information (using
xdp_rxq_info_reg() in function mvpp2_rxq_init()) we tell it to use
rxq->id as the queue id. This value is computed as:
rxq->id = port->id * max_rxq_count + queue_id
where max_rxq_count depends on the device version. In the MACCHIATOBin
case, this value is 32, meaning that rx queues on eth2 are numbered
from 32 to 35 - there are four of them.
Clearly, this is not the per-port queue id that XDP is expecting:
it wants a value in the range [0..3]. It shall directly use queue_id
which is stored in rxq->logic_rxq -- so let's use that value instead.
rxq->id is left untouched ; its value is indeed valid but it should
not be used in this context.
This is consistent with the remaining part of the code in
mvpp2_rxq_init().
With this change, packet capture is working as expected on all the
MACCHIATOBin ports.

commit 1a1aa356ddf3f16539f5962c01c5f702686dfc15 upstream.
iavf_set_ringparams doesn't communicate to the user that
1. The user requested descriptor count is out of range. Instead it
just quietly sets descriptors to the "clamped" value and calls it
done. This makes it look an invalid value was successfully set as
the descriptor count when this isn't actually true.
2. The user provided descriptor count needs to be inflated for alignment
reasons.
This behavior is confusing. The ice driver has already addressed this
by rejecting invalid values for descriptor count and
messaging for alignment adjustments.
Do the same thing here by adding the error and info messages.

commit 7e4dcc13965c57869684d57a1dc6dd7be589488c upstream.
If the PF experiences an FLR, the VF's MSI and MSI-X configuration will
be conveniently and silently removed in the process. When this happens,
reset recovery will appear to complete normally but no traffic will
pass. The netdev watchdog will helpfully notify everyone of this issue.
To prevent such public embarrassment, restore MSI configuration at every
reset. For normal resets, this will do no harm, but for VF resets
resulting from a PF FLR, this will keep the VF working.

If the hardware is constantly receiving unicast or broadcast packets
during driver load, the device previously counted many GLV_RDPC (VSI
dropped packets) events during init. This causes confusing dropped
packet statistics during driver load. The dropped packets counter
incrementing does stop once the driver finishes loading.
Avoid this problem by baselining our statistics at the end of driver
open instead of the end of probe.

commit d43b75fbc23f0ac1ef9c14a5a166d3ccb761a451 upstream.
After the below patch, the conntrack attached to skb is set to "notrack" in
the context of vrf device, for locally generated packets.
But this is true only when the default qdisc is set to the vrf device. When
changing the qdisc, notrack is not set anymore.
In fact, there is a shortcut in the vrf driver, when the default qdisc is
set, see commit dcdd43c41e60 ("net: vrf: performance improvements for
IPv4") for more details.
This patch ensures that the behavior is always the same, whatever the qdisc
is.
To demonstrate the difference, a new test is added in conntrack_vrf.sh.

commit 49201b90af818654c5506a0decc18e111eadcb66 upstream.
On some AMD hardware laptops, the system fails communicating with the
PMC when entering s2idle and the machine is battery powered.
Hardware description: HP Pavilion Aero Laptop 13-be0097nr
CPU: AMD Ryzen 7 5800U with Radeon Graphics
GPU: 03:00.0 VGA compatible controller [0300]: Advanced Micro Devices,
Inc. [AMD/ATI] Device [1002:1638] (rev c1)
Detailed description of the problem (and investigation) here:
https://gitlab.freedesktop.org/drm/amd/-/issues/1799
Patch is a single line: reduce the polling delay in half, from 100uSec
to 50uSec when waiting for a change in state from the PMC after a
write command operation.
After changing the delay, I did not see a single failure on this
machine (I have this fix for now more than one week and s2idle worked
every single time on battery power).

commit 04ec4e6250e5f58b525b08f3dca45c7d7427620e upstream.
Martyn Welch reports that his CPU port is unable to link where it has
been necessary to use one of the switch ports with an internal PHY for
the CPU port. The reason behind this is the port control register is
left forcing the link down, preventing traffic flow.
This occurs because during initialisation, phylink expects the link to
be down, and DSA forces the link down by synthesising a call to the
DSA drivers phylink_mac_link_down() method, but we don't touch the
forced-link state when we later reconfigure the port.
Resolve this by also unforcing the link state when we are operating in
PHY mode and the PPU is set to poll the PHY to retrieve link status
information.

commit 2b29cb9e3f7f038c7f50ad2583b47caf5cb1eaf2 upstream.
This commit fixes a misunderstanding in commit 4a3e0aeddf09 ("net: dsa:
mv88e6xxx: don't use PHY_DETECT on internal PHY's").
For Marvell DSA switches with the PHY_DETECT bit (for non-6250 family
devices), controls whether the PPU polls the PHY to retrieve the link,
speed, duplex and pause status to update the port configuration. This
applies for both internal and external PHYs.
For some switches such as 88E6352 and 88E6390X, PHY_DETECT has an
additional function of enabling auto-media mode between the internal
PHY and SERDES blocks depending on which first gains link.
The original intention of commit 5d5b231da7ac (net: dsa: mv88e6xxx: use
PHY_DETECT in mac_link_up/mac_link_down) was to allow this bit to be
used to detect when this propagation is enabled, and allow software to
update the port configuration. This has found to be necessary for some
switches which do not automatically propagate status from the SERDES to
the port, which includes the 88E6390. However, commit 4a3e0aeddf09
("net: dsa: mv88e6xxx: don't use PHY_DETECT on internal PHY's") breaks
this assumption.
Maarten Zanders has confirmed that the issue he was addressing was for
an 88E6250 switch, which does not have a PHY_DETECT bit in bit 12, but
instead a link status bit. Therefore, mv88e6xxx_port_ppu_updates() does
not report correctly.
This patch resolves the above issues by reverting Maarten's change and
instead making mv88e6xxx_port_ppu_updates() indicate whether the port
is internal for the 88E6250 family of switches.
Yes, you're right, I'm targeting the 6250 family. And yes, your
suggestion would solve my case and is a better implementation for
the other devices (as far as I can see).

commit f58ac1adc76b5beda43c64ef359056077df4d93a upstream.
With the design of this driver, this condition is often triggered.
However, the counter that this interrupt indicates an overflow is never
read either, so overflowing is harmless.
On my system, when a CAN bus starts flapping up and down, this locks up
the whole system with lots of interrupts and printks.
Specifically, this interrupt indicates the CEL field of ECR has
overflowed. All reads of ECR mask out CEL.

When testing the CAN controller on our Ekhart Lake hardware, we

this. Intel's support has confirmed to us that 200MHz is indeed the
correct clock rate.

commit 31cb32a590d62b18f69a9a6d433f4e69c74fdd56 upstream.
In m_can_read_fifo(), if the second call to m_can_fifo_read() fails,
the function jump to the out_fail label and returns without calling
m_can_receive_skb(). This means that the skb previously allocated by
alloc_can_skb() is not freed. In other terms, this is a memory leak.
This patch adds a goto label to destroy the skb if an error occurs.

commit 27a030e8729255b2068f35c1cd609b532b263311 upstream.
Commit 5fa6863ba692 ("spi: Check we have a spi_device_id for each DT
compatible") added a test to check that every SPI driver has a
spi_device_id for each DT compatiable string defined by the driver
and warns if the spi_device_id is missing. The spi_device_ids are
missing for the dataflash driver and the following warnings are now
seen.
WARNING KERN SPI driver mtd_dataflash has no spi_device_id for atmel,at45
WARNING KERN SPI driver mtd_dataflash has no spi_device_id for atmel,dataflash
Fix this by adding the necessary spi_device_ids.

commit 93020953d0fa7035fd036ad87a47ae2b7aa4ae33 upstream.
Many HID drivers assume that the HID device assigned to them is a USB
device as that was the only way HID devices used to be able to be
created in Linux. However, with the additional ways that HID devices
can be created for many different bus types, that is no longer true, so
properly check that we have a USB device associated with the HID device
before allowing a driver that makes this assumption to claim it.

commit 720ac467204a70308bd687927ed475afb904e11b upstream.
The wacom driver accepts devices of more than just USB types, but some
code paths can cause problems if the device being controlled is not a
USB device due to a lack of checking. Add the needed checks to ensure
that the USB device accesses are only happening on a "real" USB device,
and not one on some other bus.

commit 918aa1ef104d286d16b9e7ef139a463ac7a296f0 upstream.
When emulating the device through uhid, there is a chance we don't have
output reports and so report_field is null.

commit f237d9028f844a86955fc9da59d7ac4a5c55d7d5 upstream.
Some HID drivers are only for USB drivers, yet did not depend on
CONFIG_USB_HID. This was hidden by the fact that the USB functions were
stubbed out in the past, but now that drivers are checking for USB
devices properly, build errors can occur with some random
configurations.

The chicony HID driver only controls USB devices, yet did not have a
dependancy on USB_HID. This causes build errors on some configurations
like sparc when building due to new changes to the chicony driver.

commit f83baa0cb6cfc92ebaf7f9d3a99d7e34f2e77a8a upstream.
A number of HID drivers already call hid_is_using_ll_driver() but only
for the detection of if this is a USB device or not. Make this more
obvious by creating hid_is_usb() and calling the function that way.
Also converts the existing hid_is_using_ll_driver() functions to use the
new call.

commit 086e81f6b90e41a07a1a885bb11e93daa6915747 upstream.
Fixes spurious wakeups from s0ix on Lenovo ThinkPad X1 Cargon Gen 9 on
lid close.
These wakeups are generated by interrupts from the ISH on changes to the
lid status.
By disabling the wake IRQ from the ISH we inhibit these spurious
wakeups while keeping the resume from LID open through the ACPI
interrupt.
Reports on the Lenovo forums indicate that Lenovo ThinkPad X1 Yoga Gen6
is also affected.
