There are only 2 callers of scif_get_new_port() and both appear to get the error handling wrong. Both treat zero returns as error, but it actually returns negative error codes and >= 0 on success.

There is a bug in regards to deferred probing within the drivers core that causes GPIO-driver to suspend after its users. The bug appears if GPIO-driver probe is getting deferred, which happens after introducing dependency on PINCTRL-driver for the GPIO-driver by defining "gpio-ranges" property in device-tree. The bug in the drivers core is old (more than 4 years now) and is well known, unfortunately there is no easy fix for it. The good news is that we can workaround the deferred probe issue by changing GPIO / PINCTRL drivers registration order and hence by moving PINCTRL driver registration to the arch_init level and GPIO to the subsys_init.

The USB completion callback does not disable interrupts while acquiring the lock. We want to remove the local_irq_disable() invocation from __usb_hcd_giveback_urb() and therefore it is required for the callback handler to disable the interrupts while acquiring the lock. The callback may be invoked either in IRQ or BH context depending on the USB host controller. Use the _irqsave() variant of the locking primitives.

During raid5 replacement, the stripes can be marked with R5_NeedReplace flag. Data can be read from being-replaced devices and written to replacing spares without reading all other devices. (It's 'replace' mode. s.replacing = 1) If a being-replaced device is dropped, the replacement progress will be interrupted and resumed with pure recovery mode. However, existing stripes before being interrupted cannot read from the dropped device anymore. It prints lots of WARN_ON messages. And it results in data corruption because existing stripes write problematic data into its replacement device and update the progress.
# Erase disks (1MB + 2GB) dd if=/dev/zero of=/dev/sda bs=1MB count=2049 dd if=/dev/zero of=/dev/sdb bs=1MB count=2049 dd if=/dev/zero of=/dev/sdc bs=1MB count=2049 dd if=/dev/zero of=/dev/sdd bs=1MB count=2049 mdadm -C /dev/md0 -amd -R -l5 -n3 -x0 /dev/sd[abc] -z 2097152 # Ensure array stores non-zero data dd if=/root/data_4GB.iso of=/dev/md0 bs=1MB # Start replacement mdadm /dev/md0 -a /dev/sdd mdadm /dev/md0 --replace /dev/sda
Then, Hot-plug out /dev/sda during recovery, and wait for recovery done. echo check > /sys/block/md0/md/sync_action cat /sys/block/md0/md/mismatch_cnt # it will be greater than 0.
Soon after you hot-plug out /dev/sda, you will see many WARN_ON messages. The replacement recovery will be interrupted shortly. After the recovery finishes, it will result in data corruption.
Actually, it's just an unhandled case of replacement. In commit <f94c0b6658c7> (md/raid5: fix interaction of 'replace' and 'recovery'.), if a NeedReplace device is not UPTODATE then that is an error, the commit just simply print WARN_ON but also mark these corrupted stripes with R5_WantReplace. (it means it's ready for writes.)
To fix this case, we can leverage 'sync and replace' mode mentioned in commit <9a3e1101b827> (md/raid5: detect and handle replacements during recovery.). We can add logics to detect and use 'sync and replace' mode for these stripes.

[ Upstream commit 3f259111583801013cb605bb4414aa529adccf1c ]
The QCA4019 hw1.0 firmware 10.4-3.2.1-00050 and 10.4-3.5.3-00053 (and most likely all other) seem to ignore the WMI_CHAN_FLAG_DFS flag during the scan. This results in transmission (probe requests) on channels which are not "available" for transmissions.
Since the firmware is closed source and nothing can be done from our side to fix the problem in it, the driver has to work around this problem. The WMI_CHAN_FLAG_PASSIVE seems to be interpreted by the firmware to not scan actively on a channel unless an AP was detected on it. Simple probe requests will then be transmitted by the STA on the channel.
ath10k must therefore also use this flag when it queues a radar channel for scanning. This should reduce the chance of an active scan when the channel might be "unusable" for transmissions.

When receiving a beacon or probe response, we should update the boottime_ns field which is the timestamp the frame was received at. (cf mac80211.h)
This fixes a scanning issue with Android since it relies on this timestamp to determine when the AP has been seen for the last time (via the nl80211 BSS_LAST_SEEN_BOOTTIME parameter).

isa_virt_to_bus() & isa_bus_to_virt() claim to treat ISA bus addresses as being identical to physical addresses, but they fail to do so in the presence of a non-zero PHYS_OFFSET.
Correct this by having them use virt_to_phys() & phys_to_virt(), which consolidates the calculations to one place & ensures that ISA bus addresses do indeed match physical addresses.

[ Upstream commit 673bc519c55843c68c3aecff71a4101e79d28d2b ]
The tx completion of multiple mgmt frames can be bundled in a single event and sent by the firmware to host, if this capability is not disabled explicitly by the host. If the host cannot handle the bundled mgmt tx completion, this capability support needs to be disabled in the wmi init cmd, sent to the firmware.
Add the host capability indication flag in the wmi ready command, to let firmware know the features supported by the host driver. This field is ignored if it is not supported by firmware.
Set the host capability indication flag(i.e. host_capab) to zero, for disabling the support of bundle mgmt tx completion. This will indicate the firmware to send completion event for every mgmt tx completion, instead of bundling them together and sending in a single event.

Fuzzing the PTI-x86-32 code with trinity showed unhandled kernel paging request oops-messages that looked a lot like silent data corruption.
Lot's of debugging and testing lead to the kexec-32bit code, which is still allocating 4k PGDs when PTI is enabled. But since it uses native_set_pud() to build the page-table, it will unevitably call into __pti_set_user_pgtbl(), which writes beyond the allocated 4k page.

Locking the root adapter for __i2c_transfer will deadlock if the device sits behind a mux-locked I2C mux. Switch to the finer-grained i2c_lock_bus with the I2C_LOCK_SEGMENT flag. If the device does not sit behind a mux-locked mux, the two locking variants are equivalent.

A sysfs write callback function needs to either return the number of consumed characters or an error.
The ad952x_store() function currently returns 0 if the input value was "0", this will signal that no characters have been consumed and the function will be called repeatedly in a loop indefinitely. Fix this by returning number of supplied characters to indicate that the whole input string has been consumed.

The function dcb_app_lookup walks the list of specified DCB APP entries, looking for one that matches a given criteria: ifindex, selector, protocol ID and optionally also priority. The "don't care" value for priority is set to 0, because that priority has not been allowed under CEE regime, which predates the IEEE standardization.
Under IEEE, 0 is a valid priority number. But because dcb_app_lookup considers zero a wild card, attempts to add an APP entry with priority 0 fail when other entries exist for a given ifindex / selector / PID triplet.
Fix by changing the wild-card value to -1.

The driver only registers one input device, which uses the screen parameters from the first T9 instance. The first T63 instance also uses those parameters.
It is incorrect to send input reports from the second instances of these objects if they are enabled: the input scaling will be wrong and the positions will be mashed together.
This also causes problems on Android if the number of slots exceeds 32.
In the future, this could be handled by looking for enabled touch object instances and creating an input device for each one.

So, make sure the partition name string used in pr_warn() has the null terminating character.

The if-block that sets a successful return value in aix_partition() uses 'lvip[].pps_per_lv' and 'n[].name' potentially uninitialized.
For example, if 'numlvs' is zero or alloc_lvn() fails, neither is initialized, but are used anyway if alloc_pvd() succeeds after it.
So, make the alloc_pvd() call conditional on their initialization.
This has been hit when attaching an apparently corrupted/stressed AIX LUN, misleading the kernel to pr_warn() invalid data and hang.

[ Upstream commit 46583e8c48c5a094ba28060615b3a7c8c576690f ]
When attaching a device to an IOMMU group with CONFIG_DEBUG_ATOMIC_SLEEP=y:
BUG: sleeping function called from invalid context at mm/slab.h:421 in_atomic(): 1, irqs_disabled(): 128, pid: 61, name: kworker/1:1 ... Call trace: ... arm_lpae_alloc_pgtable+0x114/0x184 arm_64_lpae_alloc_pgtable_s1+0x2c/0x128 arm_32_lpae_alloc_pgtable_s1+0x40/0x6c alloc_io_pgtable_ops+0x60/0x88 ipmmu_attach_device+0x140/0x334
ipmmu_attach_device() takes a spinlock, while arm_lpae_alloc_pgtable() allocates memory using GFP_KERNEL. Originally, the ipmmu-vmsa driver had its own custom page table allocation implementation using GFP_ATOMIC, hence the spinlock was fine.
Fix this by replacing the spinlock by a mutex, like the arm-smmu driver does.

Buffer overrun happens when doing memcpy. I suspect there is missing (inconsistent) checks on bitmap_size.

asihpi driver treats -1 as an own invalid PCM format, but this needs a proper cast with __force prefix since PCM format type is __bitwise. Define a constant with the proper type and use it allover.
This fixes sparse warnings like: sound/pci/asihpi/asihpi.c:315:9: warning: incorrect type in initializer (different base types)

Currently if the cm_id is not bound to any netdevice, than for such cm_id, net namespace is ignored; which is incorrect.
Regardless of cm_id bound to a netdevice or not, net namespace must match. When a cm_id is bound to a netdevice, in such case net namespace and netdevice both must match.
