First set of new device support, features and cleanups for IIO in the 5.11 cycle
Usual mixed bag of new drivers / device support + cleanups etc with the
addition of a fairly big set of yaml conversions.
Txt to yaml format conversions.
In some cases dropped separate binding and moved to trivial devices (drop).

New device support
* adi,ad5685
- Add support for AD5338R dual output 10-bit DAC
- Add DT-binding doc.
* mediatek,mt6360
- New driver for this SoC ADC with bindings and using new channel label
support in the IIO core.
* st,lsm6dsx
- Add support for LSM6DST
Core:
* Add "label" to device channels, provided via a new core callback. Including
DT docs for when that is the source, and ABI docs.
* Add devm_iio_triggered_buffer_setup_ext to take extra attributes.
* dmaengine, unwrap use of iio_buffer_set_attrs()
* Drop iio_buffer_set_attrs()
* Centralize ioctl call handling. Later fix to ensure -EINVAL returned if
no handler has run.
* Fix an issue with IIO_VAL_FRACTIONAL and negative values - doesn't affect
any known existing drivers, but will impact a future one.
* kernel-doc fix in trigger.h
* file-ops ordering cleanup
Features
* semtech,sx9310
- Add control of hardware gain, proximity thresholds, hysteresis and
debounce.
- Increase what information on hardware configuration can be provided
via DT.

A couple of scheduler fixes:
- Make the conditional update of the overutilized state work correctly by
caching the relevant flags state before overwriting them and checking
them afterwards.
- Fix a data race in the wakeup path which caused loadavg on ARM64
platforms to become a random number generator.
- Fix the ordering of the iowaiter accounting operations so it can't be
decremented before it is incremented.
- Fix a bug in the deadline scheduler vs. priority inheritance when a
non-deadline task A has inherited the parameters of a deadline task B
and then blocks on a non-deadline task C.
The second inheritance step used the static deadline parameters of task
A, which are usually 0, instead of further propagating task B's
parameters. The zero initialized parameters trigger a bug in the
deadline scheduler.

mm: fix readahead_page_batch for retry entries
Both btrfs and fuse have reported faults caused by seeing a retry entry
instead of the page they were looking for. This was caused by a missing
check in the iterator.
As can be seen in the below panic log, the accessing 0x402 causes a
panic. In the xarray.h, 0x402 means RETRY_ENTRY.

mm: fix phys_to_target_node() and memory_add_physaddr_to_nid() exports
The core-mm has a default __weak implementation of phys_to_target_node()
to mirror the weak definition of memory_add_physaddr_to_nid(). That
symbol is exported for modules. However, while the export in
mm/memory_hotplug.c exported the symbol in the configuration cases of:
CONFIG_NUMA_KEEP_MEMINFO=y
CONFIG_MEMORY_HOTPLUG=y
...and:
CONFIG_NUMA_KEEP_MEMINFO=n
CONFIG_MEMORY_HOTPLUG=y
...it failed to export the symbol in the case of:
CONFIG_NUMA_KEEP_MEMINFO=y
CONFIG_MEMORY_HOTPLUG=n
Not only is that broken, but Christoph points out that the kernel should
not be exporting any __weak symbol, which means that
memory_add_physaddr_to_nid() example that phys_to_target_node() copied
is broken too.
Rework the definition of phys_to_target_node() and
memory_add_physaddr_to_nid() to not require weak symbols. Move to the
common arch override design-pattern of an asm header defining a symbol
to replace the default implementation.
The only common header that all memory_add_physaddr_to_nid() producing
architectures implement is asm/sparsemem.h. In fact, powerpc already
defines its memory_add_physaddr_to_nid() helper in sparsemem.h.
Double-down on that observation and define phys_to_target_node() where
necessary in asm/sparsemem.h. An alternate consideration that was
discarded was to put this override in asm/numa.h, but that entangles
with the definition of MAX_NUMNODES relative to the inclusion of
linux/nodemask.h, and requires powerpc to grow a new header.
The dependency on NUMA_KEEP_MEMINFO for DEV_DAX_HMEM_DEVICES is invalid
now that the symbol is properly exported / stubbed in all combinations
of CONFIG_NUMA_KEEP_MEMINFO and CONFIG_MEMORY_HOTPLUG.

compiler-clang: remove version check for BPF Tracing
bpftrace parses the kernel headers and uses Clang under the hood.
Remove the version check when __BPF_TRACING__ is defined (as bpftrace
does) so that this tool can continue to parse kernel headers, even with
older clang sources.

iio: triggered-buffer: add {devm_}iio_triggered_buffer_setup_ext variants
This change adds a parameter to the {devm_}iio_triggered_buffer_setup()
functions to assign the extra sysfs buffer attributes that are typically
assigned via iio_buffer_set_attrs().
The functions also get renamed to iio_triggered_buffer_setup_ext() &
devm_iio_triggered_buffer_setup_ext().
For backwards compatibility the old {devm_}iio_triggered_buffer_setup()
functions are now macros wrap the new (renamed) functions with NULL for the
buffer attrs.
The aim is to remove iio_buffer_set_attrs(), so in the
iio_triggered_buffer_setup_ext() function the attributes are assigned
directly to 'buffer->attrs'.
When adding multiple IIO buffers per IIO device, it can be pretty
cumbersome to first allocate a set of buffers, then to dig them out of IIO
to assign extra attributes (with iio_buffer_set_attrs()).
Naturally, the best way would be to provide them at allocation time, which
is what this change does.
At this moment, buffers allocated with {devm_}iio_triggered_buffer_setup()
are the only ones in mainline IIO to call iio_buffer_set_attrs().

spi: Fixes for v5.10
This is a relatively large set of fixes, the bulk of it being a series from Lukas Wunner which fixes confusion with the lifetime of driver data allocated along with the SPI controller structure that's been created as part of the conversion to devm APIs. The simplest fix, explained in detail in Lukas' commit message, is to move to a devm_ function for allocation of the controller and hence driver data in order to push the free of that after anything tries to reference the driver data in the remove path. This results in a relatively large diff due to the addition of a new function but isn't particularly complex. There's also a fix from sven van Asbroeck which fixes yet more fallout from the conflicts between the various different places one can configure the polarity of GPIOs in modern systems.

iommu/vt-d: Avoid panic if iommu init fails in tboot system
"intel_iommu=off" command line is used to disable iommu but iommu is force
enabled in a tboot system for security reason.
However for better performance on high speed network device, a new option
"intel_iommu=tboot_noforce" is introduced to disable the force on.
By default kernel should panic if iommu init fail in tboot for security
reason, but it's unnecessory if we use "intel_iommu=tboot_noforce,off".
Fix the code setting force_on and move intel_iommu_tboot_noforce
from tboot code to intel iommu code.

net/tls: Fix wrong record sn in async mode of device resync
In async_resync mode, we log the TCP seq of records until the async request
is completed. Later, in case one of the logged seqs matches the resync
request, we return it, together with its record serial number. Before this
fix, we mistakenly returned the serial number of the current record
instead.

Problem is that boosted entities (Priority Inheritance) use static DEADLINE parameters of the top priority waiter. However, there might be cases where top waiter could be a non-DEADLINE entity that is currently boosted by a DEADLINE entity from a different lock chain (i.e., nested priority chains involving entities of non-DEADLINE classes). In this case, top waiter static DEADLINE parameters could be null (initialized to 0 at fork()) and replenish_dl_entity() would hit a BUG(). Fix this by keeping track of the original donor and using its parameters when a task is boosted.

sched: Fix data-race in wakeup
Mel reported that on some ARM64 platforms loadavg goes bananas and
Will tracked it down to the following race:
CPU0 CPU1
schedule()
prev->sched_contributes_to_load = X;
deactivate_task(prev);
try_to_wake_up()
if (p->on_rq &&) // false
if (smp_load_acquire(&p->on_cpu) && // true
ttwu_queue_wakelist())
p->sched_remote_wakeup = Y;
smp_store_release(prev->on_cpu, 0);
where both p->sched_contributes_to_load and p->sched_remote_wakeup are
in the same word, and thus the stores X and Y race (and can clobber
one another's data).

scsi: libiscsi: Fix NOP race condition
iSCSI NOPs are sometimes "lost", mistakenly sent to the user-land iscsid daemon instead of handled in the kernel, as they should be, resulting in a message from the daemon like: iscsid: Got nop in, but kernel supports nop handling. This can occur because of the new forward- and back-locks, and the fact that an iSCSI NOP response can occur before processing of the NOP send is complete. This can result in "conn->ping_task" being NULL in iscsi_nop_out_rsp(), when the pointer is actually in the process of being set. To work around this, we add a new state to the "ping_task" pointer. In addition to NULL (not assigned) and a pointer (assigned), we add the state "being set", which is signaled with an INVALID pointer (using "-1").

So we add a function to deal with the usage counter for better coding.

iio: core: centralize ioctl() calls to the main chardev
The aim of this is to improve a bit the organization of ioctl() calls in IIO core. Currently the chardev is split across IIO core sub-modules/files. The main chardev has to be able to handle ioctl() calls, and if we need to add buffer ioctl() calls, this would complicate things. The 'industrialio-core.c' file will provide a 'iio_device_ioctl()' which will iterate over a list of ioctls registered with the IIO device. These can be event ioctl() or buffer ioctl() calls, or something else. Each ioctl() handler will have to return a IIO_IOCTL_UNHANDLED code (which is positive 1), if the ioctl() did not handle the call in any. This eliminates any potential ambiguities about negative error codes, which should fail the call altogether. If any ioctl() returns 0, it was considered that it was serviced successfully and the loop will exit. This change also moves the handling of the IIO_GET_EVENT_FD_IOCTL command inside 'industrialio-event.c', where this is better suited. This patch is a combination of 2 other patches from an older series: Patch 1: iio: core: add simple centralized mechanism for ioctl() handlers Link: https://lore.kernel.org/linux-iio/20200427131100.50845-6-alexandru.ardelean@analog.com/ Patch 2: iio: core: use new common ioctl() mechanism Link: https://lore.kernel.org/linux-iio/20200427131100.50845-7-alexandru.ardelean@analog.com/ Signed-off-by: Alexandru Ardelean <alexandru.ardelean@analog.com> Link: https://lore.kernel.org/r/20200924084155.99406-1-alexandru.ardelean@analog.com Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> |

ip_tunnels: Set tunnel option flag when tunnel metadata is present
Currently, we may set the tunnel option flag when the size of metadata

no matter the geneve option is present or not. As this may result in
issues on the tunnel flags consumers, this patch fixes the issue.

Pull fs freeze fix and cleanups from Darrick Wong:
"A single vfs fix for 5.10, along with two subsequent cleanups.
A very long time ago, a hack was added to the vfs fs freeze protection
code to work around lockdep complaints about XFS, which would try to
run a transaction (which requires intwrite protection) to finalize an
xfs freeze (by which time the vfs had already taken intwrite).
Fast forward a few years, and XFS fixed the recursive intwrite problem
on its own, and the hack became unnecessary. Fast forward almost a
decade, and latent bugs in the code converting this hack from freeze
flags to freeze locks combine with lockdep bugs to make this reproduce
frequently enough to notice page faults racing with freeze.
Since the hack is unnecessary and causes thread race errors, just get
rid of it completely. Making this kind of vfs change midway through a
cycle makes me nervous, but a large enough number of the usual
VFS/ext4/XFS/btrfs suspects have said this looks good and solves a
real problem vector.
And once that removal is done, __sb_start_write is now simple enough
that it becomes possible to refactor the function into smaller,
simpler static inline helpers in linux/fs.h. The cleanup is
straightforward.
Summary:
- Finally remove the "convert to trylock" weirdness in the fs freezer
code. It was necessary 10 years ago to deal with nested
transactions in XFS, but we've long since removed that; and now
this is causing subtle race conditions when lockdep goes offline
and sb_start_* aren't prepared to retry a trylock failure.
- Minor cleanups of the sb_start_* fs freeze helpers"
* tag 'vfs-5.10-fixes-2' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux:
vfs: move __sb_{start,end}_write* to fs.h

spi: Introduce device-managed SPI controller allocation
SPI driver probing currently comprises two steps, whereas removal
comprises only one step:
spi_alloc_master()
spi_register_controller()
spi_unregister_controller()
That's because spi_unregister_controller() calls device_unregister()
instead of device_del(), thereby releasing the reference on the
spi_controller which was obtained by spi_alloc_master().
An SPI driver's private data is contained in the same memory allocation
as the spi_controller struct. Thus, once spi_unregister_controller()
has been called, the private data is inaccessible. But some drivers
need to access it after spi_unregister_controller() to perform further
teardown steps.
Introduce devm_spi_alloc_master() and devm_spi_alloc_slave(), which
release a reference on the spi_controller struct only after the driver
has unbound, thereby keeping the memory allocation accessible. Change
spi_unregister_controller() to not release a reference if the
spi_controller was allocated by one of these new devm functions.
The present commit is small enough to be backportable to stable.
It allows fixing drivers which use the private data in their ->remove()
hook after it's been freed. It also allows fixing drivers which neglect
to release a reference on the spi_controller in the probe error path.
Long-term, most SPI drivers shall be moved over to the devm functions
introduced herein. The few that can't shall be changed in a treewide
commit to explicitly release the last reference on the controller.
That commit shall amend spi_unregister_controller() to no longer release
a reference, thereby completing the migration.
As a result, the behaviour will be less surprising and more consistent
with subsystems such as IIO, which also includes the private data in the
allocation of the generic iio_dev struct, but calls device_del() in
iio_device_unregister().
