Formatting a thin-provisioned (ESE) device that is part of a PPRC copy
relation might fail with the following error:
dasd-eckd 0.0.f500: An error occurred in the DASD device driver, reason=09
[...]
24 Byte: 0 MSG 4, no MSGb to SYSOP
During format of an ESE disk the Release Allocated Space command is used.
A bit in the payload of the command is set that is not allowed to be set
for devices in a copy relation. This bit is set to allow the partial
release of an extent.
Check for the existence of a copy relation before setting the respective
bit.

When class_dev_iter is initialized, the reference count for the subsys
private structure is incremented, but never decremented, causing a
memory leak over time. To resolve this, save off a pointer to the
internal structure into the class_dev_iter structure and then when the
iterator is finished, drop the reference count.

Two dma_wmb() are added in the XDP TX path to ensure proper ordering of
descriptor and buffer updates:
1. A dma_wmb() is added after updating the last BD to make sure
the updates to rest of the descriptor are visible before
transferring ownership to FEC.
2. A dma_wmb() is also added after updating the bdp to ensure these
updates are visible before updating txq->bd.cur.
3. Start the xmit of the frame immediately right after configuring the
tx descriptor.

Avoid early devlink info return if errors arise with MCDI commands
executed for getting the required info from the device. The rationale
is some commands can fail but later ones could still give useful data.
Moreover, some nvram partitions could not be present which needs to be
handled as a non error.
The specific errors are reported through system messages and if any
error appears, it will be reported generically through extack.

NAPI gets called with budget of 0 from netpoll, which has interrupts
disabled. We should try to free some space on Tx rings and nothing
else.
Specifically do not try to handle XDP TX or try to refill Rx buffers -
we can't use the page pool from IRQ context. Don't check if IRQs moved,
either, that makes no sense in netpoll. Netpoll calls _all_ the rings
from whatever CPU it happens to be invoked on.
In general do as little as possible, the work quickly adds up when
there's tens of rings to poll.
The immediate stack trace I was seeing is:
__do_softirq+0xd1/0x2c0
__local_bh_enable_ip+0xc7/0x120
</IRQ>

AFAIU page pool takes a BH lock, releases it and since BH is now

Currently in cdc_ncm_check_tx_max(), if dwNtbOutMaxSize is lower than
the calculated "min" value, but greater than zero, the logic sets
tx_max to dwNtbOutMaxSize. This is then used to allocate a new SKB in
cdc_ncm_fill_tx_frame() where all the data is handled.
For small values of dwNtbOutMaxSize the memory allocated during
alloc_skb(dwNtbOutMaxSize, GFP_ATOMIC) will have the same size, due to
how size is aligned at alloc time:
size = SKB_DATA_ALIGN(size);
size += SKB_DATA_ALIGN(sizeof(struct skb_shared_info));
Thus we hit the same bug that we tried to squash with
commit 2be6d4d16a084 ("net: cdc_ncm: Allow for dwNtbOutMaxSize to be unset or zero")
Low values of dwNtbOutMaxSize do not cause an issue presently because at
alloc_skb() time more memory (512b) is allocated than required for the
SKB headers alone (320b), leaving some space (512b - 320b = 192b)
for CDC data (172b).
However, if more elements (for example 3 x u64 = [24b]) were added to
one of the SKB header structs, say 'struct skb_shared_info',
increasing its original size (320b [320b aligned]) to something larger
(344b [384b aligned]), then suddenly the CDC data (172b) no longer
fits in the spare SKB data area (512b - 384b = 128b).
Consequently the SKB bounds checking semantics fails and panics:
skbuff: skb_over_panic: text:ffffffff831f755b len:184 put:172 head:ffff88811f1c6c00 data:ffff88811f1c6c00 tail:0xb8 end:0x80 dev:<NULL>

Display Fixes:
+ Catalog fixes:
- fix the programmable fetch lines and qos settings of msm8998
to match what is present downstream
- fix the LM pairs for msm8998 to match what is present downstream.
The current settings are not right as LMs with incompatible
connected blocks are paired
- remove unused INTF0 interrupt mask from SM6115/QCM2290 as there
is no INTF0 present on those chipsets. There is only one DSI on
index 1
- remove TE2 block from relevant chipsets because this is mainly
used for ping-pong split feature which is not supported upstream
and also for the chipsets where we are removing them in this
change, that block is not present as the tear check has been moved
to the intf block
- relocate non-MDP_TOP INTF_INTR offsets from dpu_hwio.h to
dpu_hw_interrupts.c to match where they belong
- fix the indentation for REV_7xxx interrupt masks
- fix the offset and version for dither blocks of SM8[34]50/SC8280XP
chipsets as it was incorrect
- make the ping-pong blk length 0 for appropriate chipsets as those
chipsets only have a dither ping-pong dither block but no other
functionality in the base ping-pong
- remove some duplicate register defines from INTF
+ Fix the log mask for the writeback block so that it can be enabled
correctly via debugfs
+ unregister the hdmi codec for dp during unbind otherwise it leaks
audio codec devices
+ Yaml change to fix warnings related to 'qcom,master-dsi' and
'qcom,sync-dual-dsi'

When handling UBLK_IO_FETCH_REQ, ctx->uring_lock is grabbed first, then
ub->mutex is acquired.
When handling UBLK_CMD_STOP_DEV or UBLK_CMD_DEL_DEV, ub->mutex is
grabbed first, then calling io_uring_cmd_done() for canceling uring
command, in which ctx->uring_lock may be required.
Real deadlock only happens when all the above commands are issued from
same uring context, and in reality different uring contexts are often used
for handing control command and IO command.
Fix the issue by using io_uring_cmd_complete_in_task() to cancel command
in ublk_cancel_dev(ublk_cancel_queue).

If a userspace application performes a "delete_controller" command

Fix the crash by checking the NVME_CTRL_STARTED_ONCE bit;
if it's not set it means that the nvme controller is still
in the process of getting initialized and the kernel
will return an -EBUSY error to userspace.
Set the NVME_CTRL_STARTED_ONCE later in the nvme_start_ctrl()
function, after the controller start operation is completed.

These don't do anything anymore, the only user of the symbol was
VFIO_CCW/AP which already "depends on VFIO" and VFIO itself selects
IOMMU_API.
When this was added VFIO was wrongly doing "depends on IOMMU_API" which
required some contortions like this to ensure IOMMU_API was turned on.

Use "a" constraint instead of "d" constraint to pass the state parameter to
the do_sqbs() inline assembly. This prevents that general purpose register
zero is used for the state parameter.
If the compiler would select general purpose register zero this would be
problematic for the used instruction in rsy format: the register used for
the state parameter is a base register. If the base register is general
purpose register zero the contents of the register are unexpectedly ignored
when the instruction is executed.
This only applies to z/VM guests using QIOASSIST with dedicated (pass through)
QDIO-based devices such as FCP [zfcp driver] as well as real OSA or
HiperSockets [qeth driver].
A possible symptom for this case using zfcp is the following repeating kernel
message pattern:
zfcp <devbusid>: A QDIO problem occurred
zfcp <devbusid>: A QDIO problem occurred
zfcp <devbusid>: qdio: ZFCP on SC <sc> using AI:1 QEBSM:1 PRI:1 TDD:1 SIGA: W
zfcp <devbusid>: A QDIO problem occurred
zfcp <devbusid>: A QDIO problem occurred
Each of the qdio problem message can be accompanied by the following entries
for the affected subchannel <sc> in
/sys/kernel/debug/s390dbf/qdio_error/hex_ascii for zfcp or qeth:
<sc> ccq: 69....
<sc> SQBS ERROR.

The XPCS expects clause 73 (copper backplane) autoneg to follow the
ethtool autoneg bit. It actually did that until the blamed
commit inaptly replaced state->an_enabled (coming from ethtool) with
phylink_autoneg_inband() (coming from the device tree or struct
phylink_config), as part of an unrelated phylink_pcs API conversion.
Russell King suggests that state->an_enabled from the original code was
just a proxy for the ethtool Autoneg bit, and that the correct way of
restoring the functionality is to check for this bit in the advertising
mask.

In suspend and resume cycle, the removal and rescan of device ends
up in NULL pointer dereference.
During driver initialization, if the ipc_imem_wwan_channel_init()
fails to get the valid device capabilities it returns an error and
further no resource (wwan struct) will be allocated. Now in this
situation if driver removal procedure is initiated it would result
in NULL pointer exception since unallocated wwan struct is dereferenced
inside ipc_wwan_deinit().
ipc_imem_run_state_worker() to handle the called functions return value
and to release the resource in failure case. It also reports the link
down event in failure cases. The user space application can handle this
event to do a device reset for restoring the device communication.
