fib has two modes:
1. Obtain output device according to source or destination address
2. Obtain the type of the address, e.g. local, unicast, multicast.
'fib daddr type' should return 'local' if the address is configured
in this netns or unicast otherwise.
'fib daddr . iif type' should return 'local' if the address is configured
on the input interface or unicast otherwise, i.e. more restrictive.
However, if the interface is part of a VRF, then 'fib daddr type'
returns unicast even if the address is configured on the incoming
interface.
This is broken for both ipv4 and ipv6.
In the ipv4 case, inet_dev_addr_type must only be used if the
'iif' or 'oif' (strict mode) was requested.
Else inet_addr_type_dev_table() needs to be used and the correct
dev argument must be passed as well so the correct fib (vrf) table
is used.
In the ipv6 case, the bug is similar, without strict mode, dev is NULL
so .flowi6_l3mdev will be set to 0.
Add a new 'nft_fib_l3mdev_master_ifindex_rcu()' helper and use that
to init the .l3mdev structure member.
For ipv6, use it from nft_fib6_flowi_init() which gets called from
both the 'type' and the 'route' mode eval functions.
This provides consistent behaviour for all modes for both ipv4 and ipv6:
If strict matching is requested, the input respectively output device
of the netfilter hooks is used.
Otherwise, use skb->dev to obtain the l3mdev ifindex.
Without this, most type checks in updated nft_fib.sh selftest fail:
FAIL: did not find veth0 . 10.9.9.1 . local in fibtype4
FAIL: did not find veth0 . dead:1::1 . local in fibtype6
FAIL: did not find veth0 . dead:9::1 . local in fibtype6

FAIL: did not find tvrf . dead:1::1 . local in fibtype6
FAIL: did not find tvrf . dead:9::1 . local in fibtype6
FAIL: fib expression address types match (iif in vrf)
(fib errounously returns 'unicast' for all of them, even
though all of these addresses are local to the vrf).

In struct usb_function, the struct usb_function_instance pointer
variable "fi" is listed as const, but it is written to in numerous
places, making the const marking of it a total lie. Fix this up by just
removing the const pointer attribute as this is modified in numerous
places.

As long as recvmsg() or recvmmsg() is used with cmsg, it is not
possible to avoid receiving file descriptors via SCM_RIGHTS.
This behaviour has occasionally been flagged as problematic, as
it can be (ab)used to trigger DoS during close(), for example, by
passing a FUSE-controlled fd or a hung NFS fd.
For instance, as noted on the uAPI Group page [0], an untrusted peer
could send a file descriptor pointing to a hung NFS mount and then
close it. Once the receiver calls recvmsg() with msg_control, the
descriptor is automatically installed, and then the responsibility
for the final close() now falls on the receiver, which may result
in blocking the process for a long time.
Regarding this, systemd calls cmsg_close_all() [1] after each
recvmsg() to close() unwanted file descriptors sent via SCM_RIGHTS.
However, this cannot work around the issue at all, because the final
fput() may still occur on the receiver's side once sendmsg() with
SCM_RIGHTS succeeds. Also, even filtering by LSM at recvmsg() does
not work for the same reason.
Thus, we need a better way to refuse SCM_RIGHTS at sendmsg().
Let's introduce SO_PASSRIGHTS to disable SCM_RIGHTS.
Note that this option is enabled by default for backward
compatibility.

As explained in the next patch, SO_PASSRIGHTS would have a problem
if we assigned a corresponding bit to socket->flags, so it must be
managed in struct sock.
Mixing socket->flags and sk->sk_flags for similar options will look
confusing, and sk->sk_flags does not have enough space on 32bit system.
Also, as mentioned in commit 16e572626961 ("af_unix: dont send
SCM_CREDENTIALS by default"), SOCK_PASSCRED and SOCK_PASSPID handling
is known to be slow, and managing the flags in struct socket cannot
avoid that for embryo sockets.
Let's move SOCK_PASS{CRED,PIDFD,SEC} to struct sock.
While at it, other SOCK_XXX flags in net.h are grouped as enum.
Note that assign_bit() was atomic, so the writer side is moved down
after lock_sock() in setsockopt(), but the bit is only read once
in sendmsg() and recvmsg(), so lock_sock() is not needed there.

SCM_CREDENTIALS and SCM_SECURITY can be recv()ed by calling
scm_recv() or scm_recv_unix(), and SCM_PIDFD is only used by
scm_recv_unix().
scm_recv() is called from AF_NETLINK and AF_BLUETOOTH.
scm_recv_unix() is literally called from AF_UNIX.
Let's restrict SO_PASSCRED and SO_PASSSEC to such sockets and
SO_PASSPIDFD to AF_UNIX only.
Later, SOCK_PASS{CRED,PIDFD,SEC} will be moved to struct sock
and united with another field.

scm_recv() has been placed in scm.h since the pre-git era for no
particular reason (I think), which makes the file really fragile.
For example, when you move SOCK_PASSCRED from include/linux/net.h to
enum sock_flags in include/net/sock.h, you will see weird build failure
due to terrible dependency.
To avoid the build failure in the future, let's move scm_recv(_unix())?
and its callees to scm.c.
Note that only scm_recv() needs to be exported for Bluetooth.
scm_send() should be moved to scm.c too, but I'll revisit later.

On cifs, "DIO reads" (specified by O_DIRECT) need to be differentiated from
"unbuffered reads" (specified by cache=none in the mount parameters). The
difference is flagged in the protocol and the server may behave
differently: Windows Server will, for example, mandate that DIO reads are
block aligned.
Fix this by adding a NETFS_UNBUFFERED_READ to differentiate this from
NETFS_DIO_READ, parallelling the write differentiation that already exists.
cifs will then do the right thing.

Originally, the file pages collapse was intended for tmpfs/shmem to merge
into THP in the background. However, now not only tmpfs/shmem can support
large folios, but some other file systems (such as XFS, erofs ...) also
support large folios. Therefore, it is time to decouple the support of
file folios collapse from SHMEM.

The "try_" prefix is confusing, since it made people believe that
try_alloc_pages() is analogous to spin_trylock() and NULL return means
EAGAIN. This is not the case. If it returns NULL there is no reason to
call it again. It will most likely return NULL again. Hence rename it to
alloc_pages_nolock() to make it symmetrical to free_pages_nolock() and
document that NULL means ENOMEM.

Having encountered a trinity report in linux-next (Linked in the 'Closes'
tag) it appears that there are legitimate situations where a file-backed
mapping can be acquired but no file->f_op->mmap or
file->f_op->mmap_prepare is set, at which point do_mmap() should simply
error out with -ENODEV.
Since previously we did not warn in this scenario and it appears we rely
upon this, restore this situation, while retaining a WARN_ON_ONCE() for
the case where both are set, which is absolutely incorrect and must be
addressed and thus always requires a warning.
If further work is required to chase down precisely what is causing this,
then we can later restore this, but it makes no sense to hold up this
series to do so, as this is existing and apparently expected behaviour.

In do_set_pmd(), we always use the folio->page to build PMD mappings for
the entire folio. Since all callers of do_set_pmd() already hold a stable
folio, converting do_set_pmd() to take a folio is safe and more
straightforward.
In addition, to ensure the extensibility of do_set_pmd() for supporting
larger folios beyond PMD size, we keep the 'page' parameter to specify
which page within the folio should be mapped.
No functional changes expected.

We've already gotten the stable locked folio in collapse_pte_mapped_thp(),
so just use folio for set_huge_pmd() to set the PMD entry, which is more
straightforward.
Moreover, we will check the folio size in do_set_pmd(), so we can remove
the unnecessary VM_BUG_ON() in set_huge_pmd(). While we are at it, we can
also remove the PageTransHuge(), as it currently has no callers.

Let's use our new interface. In remap_pfn_range(), we'll now decide
whether we have to track (full VMA covered) or only lookup the cachemode
(partial VMA covered).
Remember what we have to untrack by linking it from the VMA. When
duplicating VMAs (e.g., splitting, mremap, fork), we'll handle it similar
to anon VMA names, and use a kref to share the tracking.
Once the last VMA un-refs our tracking data, we'll do the untracking,
which simplifies things a lot and should sort our various issues we saw
recently, for example, when partially unmapping/zapping a tracked VMA.
This change implies that we'll keep tracking the original PFN range even
after splitting + partially unmapping it: not too bad, because it was not
working reliably before. The only thing that kind-of worked before was
shrinking such a mapping using mremap(): we managed to adjust the
reservation in a hacky way, now we won't adjust the reservation but leave
it around until all involved VMAs are gone.
If that ever turns out to be an issue, we could hook into VM splitting
code and split the tracking; however, that adds complexity that might not
be required, so we'll keep it simple for now.

replacement for track_pfn_insert().
For PMDs/PUDs, we keep checking a single pfn only. Add some
documentation, and also document why it is valid to not check the whole
pfn range.
We'll reuse pfnmap_setup_cachemode() from core MM next.

acpi_parse_cfmws() currently adds empty CFMWS ranges to numa_meminfo with
the expectation that numa_cleanup_meminfo moves them to
numa_reserved_meminfo. There is no need for that indirection when it is
known in advance that these unpopulated ranges are meant for
numa_reserved_meminfo in support of future hotplug / CXL provisioning.
Introduce and use numa_add_reserved_memblk() to add the empty CFMWS ranges
directly.

Other subsystems may make use of the cgroup hierarchy with the cgroup_bpf
support being one such example. For such a feature, it's useful to be able
to hook into cgroup creation and destruction paths to perform
feature-specific initializations and cleanups.
Add cgroup_lifetime_notifier which generates CGROUP_LIFETIME_ONLINE and
CGROUP_LIFETIME_OFFLINE events whenever cgroups are created and destroyed,
respectively.
The next patch will convert cgroup_bpf to use the new notifier and other
uses are planned.

ASoC: Updates for v6.16
The changes in this release are quite large, mainly in drivers rather
than the core. This is partly due to cleanups that touch a lot of
drivers and partly due to several relatively large new drivers.
- Support for automatically enumerating DAIs from standards conforming
SoundWire SDCA devices, further work is required for these to be
useful in an actual card.
- Conversion of quite a few drivers to newer GPIO APIs.
- More helpers and cleanups from Mormimoto-san.
- Support for a wider range of AVS platforms.
- Support for AMD ACP 7.x platforms, Cirrus Logic CS35L63 and CS48L32,
Everest Semiconductor ES8389, Longsoon-1 AC'97 controllers, nVidia
Tegra264, Richtek ALC203 and RT9123 and Rockchip SAI controllers.

In commit d69d80484598 ("driver core: have match() callback in struct
bus_type take a const *"), the match bus callback was changed to have
the driver be a const pointer. Unfortunately that const attribute was
thrown away when container_of() is called, which is not correct and was
not caught by the compiler due to how container_of() is implemented.
Fix this up by correctly preserving the const attribute of the driver
passed to the bus match function which requires the hdac_driver match
function to also take a const pointer for the driver structure.

to_cxlfs() was declared 'inline' in the header but only defined in
drivers/cxl/core/features.c. This has worked because features.c was
the only file using the function and the definition happened to be
available in the same compilation unit.
However, in preparation for a second .c file using the header and
needing to call the function, the inline specifier became an issue.
Sparse flagged the declaration as invalid since 'inline' requires a
visible definition at the point of use.
Defining the function in the header was considered but rejected, as
it depends on internal symbols not visible at that level.
Remove the inline specifier to correct the linkage violation.

IIO: New device support, features and cleanup for 6.16 - take 2
Note - last minute rebase was to drop a typo patch that I'd accidentally
picked up (in the microblaze arch Kconfig)
Take 2 is due to that rebase messing up some fixes tags that were
referring to patches after that point.
There is a known merge conflict due to changes in neighbouring lines.
Stephen's resolution in linux-next is:
https://lore.kernel.org/linux-next/20250506155728.65605bae@canb.auug.org.au/
Added 3 named IIO reviewers to MAINTAINERS. This is a reflection of those
who have been doing much of this work for some time. Lars-Peter is
removed from the entry having moved on to other topics. Thanks
Nuno, David and Andy for stepping up and Lars-Peter for all your
hard work in the past!
Includes the usual mix of new device support, features and general
cleanup.
This time we also have some tree wide changes.
- Rip out the iio_device_claim_direct_scoped() as it proved hard to work
with. This series includes quite a few related cleanups such as use
of guard or factoring code out to allow direct returns.
- Switch from iio_device_claim/release_direct_mode() to new
iio_device_claim/release_direct() which is structured so that sparse
can warn on failed releases. There were a few false positives but
those were mostly in code that benefited from being cleaned up as part
of this process.
- Introduce iio_push_to_buffers_with_ts() to replace the _timestamp()
version over time. This version takes the size of the supplied buffer
which the core checks is at least as big as expected by calculation
from channel descriptions of those channels enabled. Use this in
an initial set of drivers.
- Add macros for IIO_DECLARE_BUFFER_WITH_TS() and
IIO_DECLARE_DMA_BUFFER_WITH_TS() to avoid lots of fiddly code to ensure
correctly aligned buffers for timestamps being added onto the end of
channel data.
New device support
------------------
adi,ad3530r
- New driver for AD3530, AD3530R, AD3531 and AD3531R DACs with
programmable gain controls. R variants have internal references.
adi,ad7476
- Add support (dt compatible only) for the Rohm BU79100G ADC which is
fully compatible with the ti,ads7866.
adi,ad7606
- Support ad7606c-16 and ad7606c-18 devices. Includes switch to dynamic
channel information allocation.
adi,ad7380
- Add support for the AD7389-4
dfrobot,sen0322
- New driver for this oxygen sensor.
mediatek,mt2701-auxadc
- Add binding for MT6893 which is fully compatible with already supported
MT8173.
meson-saradc
- Support the GXLX SoCs. Mostly this is a workaround for some unrelated
clock control bits found in the ADC register map.
nuvoton,nct7201
- New driver for NCT7201 and NCT7202 I2C ADCs.
rohm,bd79124
- New driver for this 12-bit, 8-channel SAR ADC.
- Switch to new set_rv etc gpio callbacks that were added in 6.15.
rohm,bd79703
- Add support for BD79700, BD79701 and BD79702 DACs that have subsets of
functionality of the already supported bd79703. Included making this
driver suitable for support device variants.
st,stm32-lptimer
- Add support for stm32pm25 to this trigger.
Features
--------
Beyond IIO
- Property iterator for named children.
core
- Enable writes for 64 bit integers used for standard IIO ABI elements.
Previously these could be read only.
- Helper library that should avoid code duplication for simpler ADC
bindings that have a child node per channel.
- Enforce that IIO_DMA_MINALIGN is always at least 8 (almost always true
and simplifies code on all significant architectures)
core/backend
- Add support to control source of data - useful when the HDL includes
things like generated ramps for testing purposes. Enable this for
adi-axi-dac
adi,ad3552-hs
- Add debugfs related callbacks to allow debug access to register contents.
adi,ad4000
- Support SPI offload with appropriate FPGA firmware along with improving
documentation.
adi,ad7293
- Add support for external reference voltage.
adi,ad7606
- Support SPI offload.
adi,ad7768-1
- Support reset GPIO.
adi,admv8818
- Support filter frequencies beyond 2^32.
adi,adxl345
- Add single and double tap events.
hid-sensor-prox
- Support 16-bit report sizes as seen on some Intel platforms.
invensense,icm42600
- Enable use of named interrupts to avoid problems with some wiring choices.
Get the interrupt by name, but fallback to previous assumption on the first
being INT1 if no names are supplied.
microchip,mcp3911
- Add reset gpio support.
rohm,bh7150
- Add reset gpio support.
st,stm32
- Add support to control oversampling.
ti,adc128s052
- Add support for ROHM BD79104 which is early compatible with the TI
parts already supported by this driver. Includes some general driver
cleanup and a separate dt binding.
- Simplify reference voltage handling by assuming it is fixed after enabling
the supply.
winsen,mhz19b
- New driver for this C02 sensor.
Cleanup and minor fixes
-----------------------
dt-bindings
- Correct indentation and style for DTS examples.
- Use unevalutateProperties for SPI devices instead of additionalProperties
to allow generic SPI properties from spi-peripheral-props.yaml
ABI Docs
- Add missing docs for sampling_frequency when it applies only to events.
Treewide
- Various minor tweaks, comment fixes and similar.
- Sort TI ADCs in Kconfig that had gotten out of order.
- Switch various drives that provide GPIO chip functionality to the new
callbacks with return values.
- Standardize on { } formatting for all array sentinels.
- Make use of aligned_s64 in a few places to replace either wrong types
or manually defined equivalents.
- Drop places where spi bits_per_word is set to 8 because that is the
default anyway.
adi,ad_sigma_delta library
- Avoid a potential use of uninitialized data if reg_size has a value
that is not supported (no drivers hit this but it is reasonable hardening)
adi,ad4030
- Add error checking for scan types and no longer store it in state.
- Rework code to reduce duplication.
- Move setting the mode from buffer preenable() to update_scan_mode(),
better matching expected semantics of the two different callbacks.
- Improve data marshalling comments.
adi,ad4695
- Use u16 for buffer elements as oversampling is not yet supported except
with SPI offload (which doesn't use this path).
adi,ad5592r
- Clean up destruction of mutexes.
- Use lock guards to simplify code (later patch fixes a missed unlock)
adi,ad5933
- Correct some incorrect settling times.
adi,ad7091
- Deduplicate handling of writable vs volatile registers as they are the
inverse of each other for this device.
adi,ad7124
- Fix 3db Filter frequency.
- Remove ability to directly write the filter frequency (which was broken)
- Register naming improvements.
adi,ad7606
- Add a missing return value check.
- Fill in max sampling rates for all chips.
- Use devm_mutex_init()
- Fix up some kernel-doc formatting issues.
- Remove some camel case that snuck in.
- Drop setting address field in channels as easily established from other
fields.
- Drop unnecessary parameter to ad76060_scale_setup_cb_t.
adi,ad7768-1
- Convert to regmap.
- Factor out buffer allocation.
- Tidy up headers.
adi,ad7944
- Stop setting bits_per_word in SPI xfers with no data.
adi,ad9832
- Add of_device_id table rather than just relying on fallbacks.
- Use FIELD_PREP() to set values of fields.
adi,admv1013
- Cleanup a pointless ternary.
adi,admv8818
- Fix up LPF Band 5 frequency which was slightly wrong.
- Fix an integer overflow.
- Fix range calculation
adi,adt7316
- Replace irqd_get_trigger_type(irq_get_irq_data()) with simpler
irq_get_trigger_type()
adi,adxl345
- Use regmap cache instead of various state variables that were there to
reduce bus accesses.
- Make regmap return value checking consistent across all call sites.
adi,axi-dac
- Add a check on number of channels (0 to 15 valid)
allwinner,sun20i
- Use new adc-helpers to replace local parsing code for channel nodes.
bosch,bmp290
- Move to local variables for sensor data marshalling removing the need
for a messy definition that has to work for all supported parts.
Follow up fix adds a missing initialization.
dynaimage,al3010 and dynaimage,al3320a
- Various minor cleanup to bring these drivers inline with reviewed feedback
given on a new driver.
- Fix an error path in which power down is not called when it should be.
- Switch to regmap.
google,cros_ec
- Fix up a flexible array in middle of structure warning.
- Flush fifo when changing the timeout to avoid potential long wait
for samples.
hid-sensor-rotation
- Remove an __aligned(16) marking that doesn't seem to be justified.
kionix,kxcjk-1013
- Deduplicate code for setting up interrupts.
microchip,mcp3911
- Fix handling of conversion results register which differs across supported
devices.
idt,zopt2201
- Avoid duplicating register lists as all volatile registers are the
inverse of writeable registers on this device.
renesas,rzg2l
- Use new adc-helpers to replace local parsing code for channel nodes.
ti,ads1298
- Fix a missing Kconfig dependency.
