commit 3a29b84cf7fbf912a6ab1b9c886746f02b74ea25 upstream.
If hid_sensor_set_report_latency() fails, the error code should be returned
instead of a value likely to be interpreted as 'success'.

commit c0ec082f10b7a1fd25e8c1e2a686440da913b7a3 upstream.
Before this patch, if multiple BO_HANDLES chunks were submitted,
the error -EINVAL would be correctly set but could be overwritten
by the return value from amdgpu_cs_p1_bo_handles(). This patch
ensures that if there are multiple BO_HANDLES, we stop.

commit 26498b8d54373d31a621d7dec95c4bd842563b3b upstream.
Currently if condition (!bo and !vmw_kms_srf_ok()) was met
we go to err_out with ret == 0.
err_out dereferences vfb if ret == 0, but in our case vfb is still NULL.
Fix this by assigning sensible error to ret.

Fixes basic 2d kms setup on configurations without 3d. There's little

commit 28127dba64d8ae1a0b737b973d6d029908599611 upstream.
Include the encoder itself in its possible_clones bitmask.
In the past nothing validated that drivers were populating
possible_clones correctly, but that changed in commit
74d2aacbe840 ("drm: Validate encoder->possible_clones").
Looks like radeon never got the memo and is still not
following the rules 100% correctly.
This results in some warnings during driver initialization:
Bogus possible_clones: [ENCODER:46:TV-46] possible_clones=0x4 (full encoder mask=0x7)

commit 8fa075804cb3b00960dd5c06554308175c834530 upstream.
After the SQ cleanup fix, the CQ will receive a response with the
corresponding tag marked as OCS: ABORTED. To align with the behavior of
Legacy SDB mode, the handling of OCS: ABORTED has been changed to match
that of OCS_INVALID_COMMAND_STATUS (SDB), with both returning a SCSI
result of DID_REQUEUE.
Furthermore, the workaround implemented before the SQ cleanup fix can be
removed.

commit 19a198b67767d952c8f3d0cf24eb3100522a8223 upstream.
There is a history of deadlock if reboot is performed at the beginning
of booting. SDEV_QUIESCE was set for all LU's scsi_devices by UFS
shutdown, and at that time the audio driver was waiting on
blk_mq_submit_bio() holding a mutex_lock while reading the fw binary.
After that, a deadlock issue occurred while audio driver shutdown was
waiting for mutex_unlock of blk_mq_submit_bio(). To solve this, set
SDEV_OFFLINE for all LUs except WLUN, so that any I/O that comes down
after a UFS shutdown will return an error.

commit b9e63d6c7c0e94a99e1af7c9c0c7fad13a2f2453 upstream.
A sanity check on phy_mask was added in commit 3668651def2c ("scsi:
mpi3mr: Sanitise num_phys"). This causes warning messages when more than
64 phys are detected and devices connected to phys greater than 64 are
dropped.
The phy_mask bitmap is only needed for controller phys and not required
for expander phys. Controller phys can go up to a maximum of 64 and
therefore u64 is good enough to contain phy_mask bitmap.
To suppress those warnings and allow devices to be discovered as before
the offending commit, restrict the phy_mask setting and lowest phy
setting only to the controller phys.

commit dee3df68ab4b00fff6bdf9fc39541729af37307c upstream.
According to the VT220 specification the possible character combinations
sent on RETURN are only CR or CRLF [0].
The Return key sends either a CR character (0/13) or a CR
character (0/13) and an LF character (0/10), depending on the
set/reset state of line feed/new line mode (LNM).
The sclp/vt220 driver however uses LFCR. This can confuse tools, for
example the kunit runner.

commit 0d9dc27df22d9b5c8dc7185c8dddbc14f5468518 upstream.
On reboot the SCLP interface is deactivated through a reboot notifier.
This happens before other components using SCLP have the chance to run
their own reboot notifiers.
Two of those components are the SCLP console and tty drivers which try
to flush the last outstanding messages.
At that point the SCLP interface is already unusable and the messages
are discarded.
Execute sclp_deactivate() as late as possible to avoid this issue.

commit 6e02a277f1db24fa039e23783c8921c7b0e5b1b3 upstream.
Previously, the domain_context_clear() function incorrectly called
pci_for_each_dma_alias() to set up context entries for non-PCI devices.
This could lead to kernel hangs or other unexpected behavior.
Add a check to only call pci_for_each_dma_alias() for PCI devices. For
non-PCI devices, domain_context_clear_one() is called directly.

fixed-link PHY
commit d0c3601f2c4e12e7689b0f46ebc17525250ea8c3 upstream.
A boot delay was introduced by commit 79540d133ed6 ("net: macb: Fix
handling of fixed-link node"). This delay was caused by the call to
`mdiobus_register()` in cases where a fixed-link PHY was present. The
MDIO bus registration triggered unnecessary PHY address scans, leading
to a 20-second delay due to attempts to detect Clause 45 (C45)
compatible PHYs, despite no MDIO bus being attached.
The commit 79540d133ed6 ("net: macb: Fix handling of fixed-link node")
was originally introduced to fix a regression caused by commit
7897b071ac3b4 ("net: macb: convert to phylink"), which caused the driver
to misinterpret fixed-link nodes as PHY nodes. This resulted in warnings
like:
mdio_bus f0028000.ethernet-ffffffff: fixed-link has invalid PHY address
mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 0
...
mdio_bus f0028000.ethernet-ffffffff: scan phy fixed-link at address 31
This patch reworks the logic to avoid registering and allocation of the
MDIO bus when:
- The device tree contains a fixed-link node.
- There is no "mdio" child node in the device tree.
If a child node named "mdio" exists, the MDIO bus will be registered to
support PHYs attached to the MACB's MDIO bus. Otherwise, with only a
fixed-link, the MDIO bus is skipped.
Tested on a sama5d35 based system with a ksz8863 switch attached to
macb0.

commit 6b58fadd44aafbbd6af5f0b965063e1fd2063992 upstream.
When running "xdp-bench tx eno0" to test the XDP_TX feature of ENETC
on LS1028A, it was found that if the command was re-run multiple times,
Rx could not receive the frames, and the result of xdp-bench showed
that the rx rate was 0.
root@ls1028ardb:~# ./xdp-bench tx eno0
Hairpinning (XDP_TX) packets on eno0 (ifindex 3; driver fsl_enetc)
Summary 2046 rx/s 0 err,drop/s
Summary 0 rx/s 0 err,drop/s
Summary 0 rx/s 0 err,drop/s
Summary 0 rx/s 0 err,drop/s
By observing the Rx PIR and CIR registers, CIR is always 0x7FF and
PIR is always 0x7FE, which means that the Rx ring is full and can no
longer accommodate other Rx frames. Therefore, the problem is caused
by the Rx BD ring not being cleaned up.
Further analysis of the code revealed that the Rx BD ring will only
be cleaned if the "cleaned_cnt > xdp_tx_in_flight" condition is met.
Therefore, some debug logs were added to the driver and the current
values of cleaned_cnt and xdp_tx_in_flight were printed when the Rx
BD ring was full. The logs are as follows.
[ 178.762419] [XDP TX] >> cleaned_cnt:1728, xdp_tx_in_flight:2140
[ 178.771387] [XDP TX] >> cleaned_cnt:1941, xdp_tx_in_flight:2110
[ 178.776058] [XDP TX] >> cleaned_cnt:1792, xdp_tx_in_flight:2110
From the results, the max value of xdp_tx_in_flight has reached 2140.
However, the size of the Rx BD ring is only 2048. So xdp_tx_in_flight
did not drop to 0 after enetc_stop() is called and the driver does not
clear it. The root cause is that NAPI is disabled too aggressively,
without having waited for the pending XDP_TX frames to be transmitted,
and their buffers recycled, so that xdp_tx_in_flight cannot naturally
drop to 0. Later, enetc_free_tx_ring() does free those stale, unsent
XDP_TX packets, but it is not coded up to also reset xdp_tx_in_flight,
hence the manifestation of the bug.
One option would be to cover this extra condition in enetc_free_tx_ring(),
but now that the ENETC_TX_DOWN exists, we have created a window at
the beginning of enetc_stop() where NAPI can still be scheduled, but
any concurrent enqueue will be blocked. Therefore, enetc_wait_bdrs()
and enetc_disable_tx_bdrs() can be called with NAPI still scheduled,
and it is guaranteed that this will not wait indefinitely, but instead
give us an indication that the pending TX frames have orderly dropped
to zero. Only then should we call napi_disable().
This way, enetc_free_tx_ring() becomes entirely redundant and can be
dropped as part of subsequent cleanup.
The change also refactors enetc_start() so that it looks like the
mirror opposite procedure of enetc_stop().

commit 0a93f2ca4be6c4616d371f18a3fabad2df7f8d55 upstream.
The Tx BD rings are disabled first in enetc_stop() and the driver
waits for them to become empty. This operation is not safe while
the ring is actively transmitting frames, and will cause the ring
to not be empty and hardware exception. As described in the NETC
block guide, software should only disable an active Tx ring after
all pending ring entries have been consumed (i.e. when PI = CI).
Disabling a transmit ring that is actively processing BDs risks
a HW-SW race hazard whereby a hardware resource becomes assigned
to work on one or more ring entries only to have those entries be
removed due to the ring becoming disabled.
When testing XDP_REDIRECT feautre, although all frames were blocked
from being put into Tx rings during ring reconfiguration, the similar
warning log was still encountered:
fsl_enetc 0000:00:00.2 eno2: timeout for tx ring #6 clear
fsl_enetc 0000:00:00.2 eno2: timeout for tx ring #7 clear
The reason is that when there are still unsent frames in the Tx ring,
disabling the Tx ring causes the remaining frames to be unable to be
sent out. And the Tx ring cannot be restored, which means that even
if the xdp program is uninstalled, the Tx frames cannot be sent out
anymore. Therefore, correct the operation order in enect_start() and
enect_stop().

commit c728a95ccf2a8ba544facfc30a4418d4c68c39f0 upstream.
When testing the XDP_REDIRECT function on the LS1028A platform, we
found a very reproducible issue that the Tx frames can no longer be
sent out even if XDP_REDIRECT is turned off. Specifically, if there
is a lot of traffic on Rx direction, when XDP_REDIRECT is turned on,
the console may display some warnings like "timeout for tx ring #6
clear", and all redirected frames will be dropped, the detailed log
is as follows.

By analyzing the XDP_REDIRECT implementation of enetc driver, the
driver will reconfigure Tx and Rx BD rings when a bpf program is
installed or uninstalled, but there is no mechanisms to block the
redirected frames when enetc driver reconfigures rings. Similarly,
XDP_TX verdicts on received frames can also lead to frames being
enqueued in the Tx rings. Because XDP ignores the state set by the
netif_tx_wake_queue() API, so introduce the ENETC_TX_DOWN flag to
suppress transmission of XDP frames.

commit 412950d5746f7aa139e14fe95338694c1f09b595 upstream.
The xdp_drops statistic indicates the number of XDP frames dropped in
the Rx direction. However, enetc_xdp_drop() is also used in XDP_TX and
XDP_REDIRECT actions. If frame loss occurs in these two actions, the
frames loss count should not be included in xdp_drops, because there
are already xdp_tx_drops and xdp_redirect_failures to count the frame
loss of these two actions, so it's better to remove xdp_drops statistic
from enetc_xdp_drop() and increase xdp_drops in XDP_DROP action.

commit 0cca961a026177af69044f10d6ae76d8ce043764 upstream.
The pci_bus_release_domain_nr() API is supposed to free the domain
number allocated by pci_bus_find_domain_nr(). Most of the callers of
pci_bus_find_domain_nr(), store the domain number in pci_bus::domain_nr.
As such, the pci_bus_release_domain_nr() implicitly frees the domain
number by dereferencing 'struct pci_bus'. However, one of the callers
of this API, the PCI endpoint subsystem, doesn't have 'struct pci_bus',
so it only passes NULL. Due to this, the API will end up dereferencing
the NULL pointer.
To fix this issue, pass the domain number to this API explicitly. Since
'struct pci_bus' is not used for anything else other than extracting the
domain number, it makes sense to pass the domain number directly.

commit 640f70063e6d3a76a63f57e130fba43ba8c7e980 upstream.
When a mailbox message is received, the driver is checking for a non 0
datalen in the controlq descriptor. If it is valid, the payload is
attached to the ctlq message to give to the upper layer. However, the
payload response size given to the upper layer was taken from the buffer
metadata which is _always_ the max buffer size. This meant the API was
returning 4K as the payload size for all messages. This went unnoticed
since the virtchnl exchange response logic was checking for a response
size less than 0 (error), not less than exact size, or not greater than
or equal to the max mailbox buffer size (4K). All of these checks will
pass in the success case since the size provided is always 4K. However,
this breaks anyone that wants to validate the exact response size.
Fetch the actual payload length from the value provided in the
descriptor data_len field (instead of the buffer metadata).
Unfortunately, this means we lose some extra error parsing for variable
sized virtchnl responses such as create vport and get ptypes. However,
the original checks weren't really helping anyways since the size was
_always_ 4K.

commit 7738568885f2eaecfc10a3f530a2693e5f0ae3d0 upstream.
The dev_pm_domain_attach|detach_list() functions are not resource managed,
hence they should not use devm_* helpers to manage allocation/freeing of
data. Let's fix this by converting to the traditional alloc/free functions.

successfully.

copy push command will be sent via t |
