The same file in libdrm is, as is the tradition with the rest of libdrm,

Extend the bpf(2) syscall by two new commands, BPF_PROG_ATTACH and
BPF_PROG_DETACH which allow attaching and detaching eBPF programs
to a target.
On the API level, the target could be anything that has an fd in
userspace, hence the name of the field in union bpf_attr is called
'target_fd'.
When called with BPF_ATTACH_TYPE_CGROUP_INET_{E,IN}GRESS, the target is
expected to be a valid file descriptor of a cgroup v2 directory which
has the bpf controller enabled. These are the only use-cases
implemented by this patch at this point, but more can be added.
If a program of the given type already exists in the given cgroup,
the program is swapped automically, so userspace does not have to drop
an existing program first before installing a new one, which would
otherwise leave a gap in which no program is attached.
For more information on the propagation logic to subcgroups, please
refer to the bpf cgroup controller implementation.
The API is guarded by CAP_NET_ADMIN.

This program type is similar to BPF_PROG_TYPE_SOCKET_FILTER, except that
it does not allow BPF_LD_[ABS|IND] instructions and hooks up the

NBD can become contended on its single connection. We have to serialize all

allowing userspace to provide multiple connections to a single nbd device. This
coupled with block-mq drastically increases performance in multi-process cases.

All conflicts were simple overlapping changes except perhaps
for the Thunder driver.
That driver has a change_mtu method explicitly for sending
a message to the hardware. If that fails it returns an
error.
Normally a driver doesn't need an ndo_change_mtu method becuase those
are usually just range changes, which are now handled generically.
But since this extra operation is needed in the Thunder driver, it has
to stay.
However, if the message send fails we have to restore the original
MTU before the change because the entire call chain expects that if
an error is thrown by ndo_change_mtu then the MTU did not change.
Therefore code is added to nicvf_change_mtu to remember the original
MTU, and to restore it upon nicvf_update_hw_max_frs() failue.

This patch just adds a 'failfast' per-device flag which can be stored
in v0.90 or v1.x metadata.
The flag is not used yet but the intent is that it can be used for
mirrored (raid1/raid10) arrays where low latency is more important
than keeping all devices on-line.
Setting the flag for a device effectively gives permission for that
device to be marked as Faulty and excluded from the array on the first
error. The underlying driver will be directed not to retry requests
that result in failures. There is a proviso that the device must not
be marked faulty if that would cause the array as a whole to fail, it
may only be marked Faulty if the array remains functional, but is
degraded.
Failures on read requests will cause the device to be marked
as Faulty immediately so that further reads will avoid that
device. No attempt will be made to correct read errors by
over-writing with the correct data.
It is expected that if transient errors, such as cable unplug, are
possible, then something in user-space will revalidate failed
devices and re-add them when they appear to be working again.

This driver creates a userspace leds driver similar to uinput.
New LEDs are created by opening /dev/uleds and writing a uleds_user_dev
struct. A new LED class device is registered with the name given in the
struct. Reading will return a single byte that is the current brightness.
The poll() syscall is also supported. It will be triggered whenever the
brightness changes. Closing the file handle to /dev/uleds will remove
the leds class device.

It has been suggested that having per-plane modifiers is making life
more difficult for userspace, so let's just retire modifier[1-3] and
use modifier[0] to apply to the entire framebuffer.
Obviosuly this means that if individual planes need different tiling
layouts and whatnot we will need a new modifier for each combination
of planes with different tiling layouts.
For a bit of extra backwards compatilbilty the kernel will allow
non-zero modifier[1+] but it require that they will match modifier[0].
This in case there's existing userspace out there that sets
modifier[1+] to something non-zero with planar formats.
Mostly a cocci job, with a bit of manual stuff mixed in.

Add picture aspect ratio information, the CEA-861 VIC (Video Identification
Code) and the HDMI VIC to struct v4l2_bt_timings.
The picture aspect was chosen rather than the pixel aspect since 1) the
CEA-861 standard uses picture aspect, and 2) pixel aspect ratio can become
tricky when dealing with pixel repeat timings. While we don't support those
yet at the moment, this might become necessary. And in that case using
picture aspect ratio makes more sense. And converting picture aspect ratio
to pixel aspect ratio is easy enough.

This reverts commit a68362fe3e.
Adding new mode flags willy nilly breaks existing userspace. We need to
coordinate this better, potentially with a new client cap that only
exposes the aspect ratio flags when userspace is prepared for them
(similar to what we do with stereo 3D modes).

Netfilter updates for net-next
The following patchset contains a second batch of Netfilter updates for
your net-next tree. This includes a rework of the core hook
infrastructure that improves Netfilter performance by ~15% according to
synthetic benchmarks. Then, a large batch with ipset updates, including
a new hash:ipmac set type, via Jozsef Kadlecsik. This also includes a
couple of assorted updates.
Regarding the core hook infrastructure rework to improve performance,
using this simple drop-all packets ruleset from ingress:
nft add table netdev x
nft add chain netdev x y { type filter hook ingress device eth0 priority 0\; }
nft add rule netdev x y drop
And generating traffic through Jesper Brouer's
samples/pktgen/pktgen_bench_xmit_mode_netif_receive.sh script using -i
option. perf report shows nf_tables calls in its top 10:
17.30% kpktgend_0 [nf_tables] [k] nft_do_chain
15.75% kpktgend_0 [kernel.vmlinux] [k] __netif_receive_skb_core
10.39% kpktgend_0 [nf_tables_netdev] [k] nft_do_chain_netdev
I'm measuring here an improvement of ~15% in performance with this
patchset, so we got +2.5Mpps more. I have used my old laptop Intel(R)
Core(TM) i5-3320M CPU @ 2.60GHz 4-cores.
This rework contains more specifically, in strict order, these patches:
1) Remove compile-time debugging from core.
2) Remove obsolete comments that predate the rcu era. These days it is
well known that a Netfilter hook always runs under rcu_read_lock().
3) Remove threshold handling, this is only used by br_netfilter too.
We already have specific code to handle this from br_netfilter,
so remove this code from the core path.
4) Deprecate NF_STOP, as this is only used by br_netfilter.
5) Place nf_state_hook pointer into xt_action_param structure, so
this structure fits into one single cacheline according to pahole.
This also implicit affects nftables since it also relies on the
xt_action_param structure.
6) Move state->hook_entries into nf_queue entry. The hook_entries
pointer is only required by nf_queue(), so we can store this in the
queue entry instead.
7) use switch() statement to handle verdict cases.
8) Remove hook_entries field from nf_hook_state structure, this is only
required by nf_queue, so store it in nf_queue_entry structure.
9) Merge nf_iterate() into nf_hook_slow() that results in a much more
simple and readable function.
10) Handle NF_REPEAT away from the core, so far the only client is
nf_conntrack_in() and we can restart the packet processing using a
simple goto to jump back there when the TCP requires it.
This update required a second pass to fix fallout, fix from
Arnd Bergmann.
11) Set random seed from nft_hash when no seed is specified from
userspace.
12) Simplify nf_tables expression registration, in a much smarter way
to save lots of boiler plate code, by Liping Zhang.
13) Simplify layer 4 protocol conntrack tracker registration, from
Davide Caratti.
14) Missing CONFIG_NF_SOCKET_IPV4 dependency for udp4_lib_lookup, due
to recent generalization of the socket infrastructure, from Arnd
Bergmann.
15) Then, the ipset batch from Jozsef, he describes it as it follows:
* Cleanup: Remove extra whitespaces in ip_set.h
* Cleanup: Mark some of the helpers arguments as const in ip_set.h
* Cleanup: Group counter helper functions together in ip_set.h
* struct ip_set_skbinfo is introduced instead of open coded fields
in skbinfo get/init helper funcions.
* Use kmalloc() in comment extension helper instead of kzalloc()
because it is unnecessary to zero out the area just before
explicit initialization.
* Cleanup: Split extensions into separate files.
* Cleanup: Separate memsize calculation code into dedicated function.
* Cleanup: group ip_set_put_extensions() and ip_set_get_extensions()
together.
* Add element count to hash headers by Eric B Munson.
* Add element count to all set types header for uniform output
across all set types.
* Count non-static extension memory into memsize calculation for
userspace.
* Cleanup: Remove redundant mtype_expire() arguments, because
they can be get from other parameters.
* Cleanup: Simplify mtype_expire() for hash types by removing
one level of intendation.
* Make NLEN compile time constant for hash types.
* Make sure element data size is a multiple of u32 for the hash set
types.
* Optimize hash creation routine, exit as early as possible.
* Make struct htype per ipset family so nets array becomes fixed size
and thus simplifies the struct htype allocation.
* Collapse same condition body into a single one.
* Fix reported memory size for hash:* types, base hash bucket structure
was not taken into account.
* hash:ipmac type support added to ipset by Tomasz Chilinski.
* Use setup_timer() and mod_timer() instead of init_timer()
by Muhammad Falak R Wani, individually for the set type families.
16) Remove useless connlabel field in struct netns_ct, patch from
Florian Westphal.
17) xt_find_table_lock() doesn't return ERR_PTR() anymore, so simplify
{ip,ip6,arp}tables code that uses this.

This patch adds the necessary functions to compute and check the HMAC signature
of an SR-enabled packet. Two HMAC algorithms are supported: hmac(sha1) and
hmac(sha256).
In order to avoid dynamic memory allocation for each HMAC computation,
a per-cpu ring buffer is allocated for this purpose.
A new per-interface sysctl called seg6_require_hmac is added, allowing a
user-defined policy for processing HMAC-signed SR-enabled packets.
A value of -1 means that the HMAC field will always be ignored.
A value of 0 means that if an HMAC field is present, its validity will
be enforced (the packet is dropped is the signature is incorrect).
Finally, a value of 1 means that any SR-enabled packet that does not
contain an HMAC signature or whose signature is incorrect will be dropped.

This patch creates a new type of interfaceless lightweight tunnel (SEG6),
enabling the encapsulation and injection of SRH within locally emitted
packets and forwarded packets.
>From a configuration viewpoint, a seg6 tunnel would be configured as follows:
ip -6 ro ad fc00::1/128 encap seg6 mode encap segs fc42::1,fc42::2,fc42::3 dev eth0
Any packet whose destination address is fc00::1 would thus be encapsulated
within an outer IPv6 header containing the SRH with three segments, and would
actually be routed to the first segment of the list. If `mode inline' was
specified instead of `mode encap', then the SRH would be directly inserted
after the IPv6 header without outer encapsulation.
The inline mode is only available if CONFIG_IPV6_SEG6_INLINE is enabled. This
feature was made configurable because direct header insertion may break
several mechanisms such as PMTUD or IPSec AH.

This patch adds the necessary hooks and structures to provide support
for SR-IPv6 control plane, essentially the Generic Netlink commands
that will be used for userspace control over the Segment Routing
kernel structures.
The genetlink commands provide control over two different structures:
tunnel source and HMAC data. The tunnel source is the source address
that will be used by default when encapsulating packets into an
outer IPv6 header + SRH. If the tunnel source is set to :: then an
address of the outgoing interface will be selected as the source.
The HMAC commands currently just return ENOTSUPP and will be implemented
in a future patch.

Implement minimal support for processing of SR-enabled packets
as described in
https://tools.ietf.org/html/draft-ietf-6man-segment-routing-header-02.
This patch implements the following operations:
- Intermediate segment endpoint: incrementation of active segment and rerouting.
- Egress for SR-encapsulated packets: decapsulation of outer IPv6 header + SRH
and routing of inner packet.
- Cleanup flag support for SR-inlined packets: removal of SRH if we are the
penultimate segment endpoint.
A per-interface sysctl seg6_enabled is provided, to accept/deny SR-enabled
packets. Default is deny.
This patch does not provide support for HMAC-signed packets.

Rename the ABI struct and type because they are for configuring physical
DAIs, not only backend DAIs since users may not need DPCM:
- Rename struct snd_soc_tplg_be_dai to snd_soc_tplg_dai.
- Rename type SND_SOC_TPLG_TYPE_BE_DAI to SND_SOC_TPLG_TYPE_DAI.
This code refactoring is backward compatible because:
- Both layout of the struct and type value has no change. Kernel can
find the same type value and map to same data layout.
- This struct is not in ABI v4 at all. Now the user space uses ABI v4.

The following fields are added to physical link configuration struct
(snd_soc_tplg_link_config) in ABI v5:
- name and stream name
Topology will use them to find an existing physical link and configure
it.
- HW configurations
Define the types and ABI struct for runtime supported hardware configs
of physical DAI links, e.g. audio hardware formats. The default HW
config ID will help topology to find the DAI format to set on init.
Topology provides this as a fallback if such HW settings are not
available in ACPI or device tree, to avoid hard code in drivers. It's
only for config items that can be programmed by SW or FW, not for
physical things like link connections or GPIO used for HP etc.
- flags and private data
The flags will be used to configure an existing physical DAI link.
The private data is reserved for future extension.
NOTE: Current kernel has no support for physical links. A later patch
will add support for configuring physical links and make the support
backward compatible for ABI v4.

we also need to add a flag so that the userspace GL driver can easily

When reading a datagram or raw packet that arrived fragmented, expose
the maximum fragment size if recorded to allow applications to
estimate receive path MTU.
At this point, the field is only recorded when ipv6 connection
tracking is enabled. A follow-up patch will record this field also
in the ipv6 input path.

Netfilter updates for net-next
The following patchset contains Netfilter updates for your net-next
tree. This includes better integration with the routing subsystem for
nf_tables, explicit notrack support and smaller updates. More
specifically, they are:
1) Add fib lookup expression for nf_tables, from Florian Westphal. This
new expression provides a native replacement for iptables addrtype
and rp_filter matches. This is more flexible though, since we can
populate the kernel flowi representation to inquire fib to
accomodate new usecases, such as RTBH through skb mark.
2) Introduce rt expression for nf_tables, from Anders K. Pedersen. This
new expression allow you to access skbuff route metadata, more
specifically nexthop and classid fields.
3) Add notrack support for nf_tables, to skip conntracking, requested by
many users already.
4) Add boilerplate code to allow to use nf_log infrastructure from
nf_tables ingress.
5) Allow to mangle pkttype from nf_tables prerouting chain, to emulate
the xtables cluster match, from Liping Zhang.
6) Move socket lookup code into generic nf_socket_* infrastructure so
we can provide a native replacement for the xtables socket match.
7) Make sure nfnetlink_queue data that is updated on every packets is
placed in a different cache from read-only data, from Florian Westphal.
8) Handle NF_STOLEN from nf_tables core, also from Florian Westphal.
9) Start round robin number generation in nft_numgen from zero,
instead of n-1, for consistency with xtables statistics match,
patch from Liping Zhang.
10) Set GFP_NOWARN flag in skbuff netlink allocations in nfnetlink_log,
given we retry with a smaller allocation on failure, from Calvin Owens.
11) Cleanup xt_multiport to use switch(), from Gao feng.

Introduces an nftables rt expression for routing related data with support
for nexthop (i.e. the directly connected IP address that an outgoing packet
is sent to), which can be used either for matching or accounting, eg.
# nft add rule filter postrouting \
ip daddr 192.168.1.0/24 rt nexthop != 192.168.0.1 drop
This will drop any traffic to 192.168.1.0/24 that is not routed via
192.168.0.1.
# nft add rule filter postrouting \
flow table acct { rt nexthop timeout 600s counter }
# nft add rule ip6 filter postrouting \
flow table acct { rt nexthop timeout 600s counter }
These rules count outgoing traffic per nexthop. Note that the timeout
releases an entry if no traffic is seen for this nexthop within 10 minutes.
# nft add rule inet filter postrouting \
ether type ip \
flow table acct { rt nexthop timeout 600s counter }
# nft add rule inet filter postrouting \
ether type ip6 \
flow table acct { rt nexthop timeout 600s counter }
Same as above, but via the inet family, where the ether type must be
specified explicitly.
"rt classid" is also implemented identical to "meta rtclassid", since it
is more logical to have this match in the routing expression going forward.

Add FIB expression, supported for ipv4, ipv6 and inet family (the latter
just dispatches to ipv4 or ipv6 one based on nfproto).
Currently supports fetching output interface index/name and the
rtm_type associated with an address.
This can be used for adding path filtering. rtm_type is useful
to e.g. enforce a strong-end host model where packets
are only accepted if daddr is configured on the interface the
packet arrived on.
The fib expression is a native nftables alternative to the
xtables addrtype and rp_filter matches.
FIB result order for oif/oifname retrieval is as follows:
- if packet is local (skb has rtable, RTF_LOCAL set, this
will also catch looped-back multicast packets), set oif to
the loopback interface.
- if fib lookup returns an error, or result points to local,
store zero result. This means '--local' option of -m rpfilter
is not supported. It is possible to use 'fib type local' or add
explicit saddr/daddr matching rules to create exceptions if this
is really needed.
- store result in the destination register.
In case of multiple routes, search set for desired oif in case
strict matching is requested.
ipv4 and ipv6 behave fib expressions are supposed to behave the same.

Each socket operates in a network namespace where it has been created,
so if we want to dump and restore a socket, we have to know its network
namespace.
We have a socket_diag to get information about sockets, it doesn't
report sockets which are not bound or connected.
This patch introduces a new socket ioctl, which is called SIOCGSKNS
and used to get a file descriptor for a socket network namespace.
A task must have CAP_NET_ADMIN in a target network namespace to
use this ioctl.

According to USB Specification 2.0 table 9-4,
wMaxPacketSize is a bitfield. Endpoint's maxpacket
is laid out in bits 10:0. For high-speed,
high-bandwidth isochronous endpoints, bits 12:11
contain a multiplier to tell us how many
transactions we want to try per uframe.
This means that if we want an isochronous endpoint
to issue 3 transfers of 1024 bytes per uframe,
wMaxPacketSize should contain the value:
1024 | (2 << 11)
or 5120 (0x1400). In order to make Host and
Peripheral controller drivers' life easier, we're
adding a helper which returns bits 12:11. Note that
no care is made WRT to checking endpoint type and
gadget's speed. That's left for drivers to handle.

Since generic netlink family IDs are small integers, allocated
densely, IDR is an ideal match for lookups. Replace the existing
hand-written hash-table with IDR for allocation and lookup.
This lets the families only be written to once, during register,
since the list_head can be removed and removal of a family won't
cause any writes.
It also slightly reduces the code size (by about 1.3k on x86-64).

Static family IDs have never really been used, the only
use case was the workaround I introduced for those users
that assumed their family ID was also their multicast
group ID.
Additionally, because static family IDs would never be
reserved by the generic netlink code, using a relatively
low ID would only work for built-in families that can be
registered immediately after generic netlink is started,
which is basically only the control family (apart from
the workaround code, which I also had to add code for so
it would reserve those IDs)
Thus, anything other than GENL_ID_GENERATE is flawed and
luckily not used except in the cases I mentioned. Move
those workarounds into a few lines of code, and then get
rid of GENL_ID_GENERATE entirely, making it more robust.

Add the ability to configure if an AP (and associated VLANs) will
do multicast-to-unicast conversion for ARP, IPv4 and IPv6 frames
(possibly within 802.1Q). If enabled, such frames are to be sent
to each station separately, with the DA replaced by their own MAC
address rather than the group address.
Note that this may break certain expectations of the receiver,
such as the ability to drop unicast IP packets received within
multicast L2 frames, or the ability to not send ICMP destination
unreachable messages for packets received in L2 multicast (which
is required, but the receiver can't tell the difference if this
new option is enabled.)
This also doesn't implement the 802.11 DMS (directed multicast

duplicate that implementation. Rename that attribute to more generic
NL80211_ATTR_AUTH_DATA (with backwards compatibility define for
NL80211_SAE_DATA).
Also document the special rules related to the Authentication
transaction number and Status code fiels.

Fair number of outreachy related patches in here. Some of these may well
have already been picked up by Greg but git will sort that out for us.
Also some good staging cleanup work from other sources. Thanks Brian and Lars
in particular for this.
New device support
* ACCES 104-quad-8
- New driver for this 8 channel encoder input board. Lots of new ABI with
this one.
* AD7766
- New driver supporting AD7766, AD7766-1, AD7766-2, AD7767, AD7767-1 and
AD7767-2 24 bit ADCs.
* dmard 10
- New driver for this 3 axis accelerometer.
* Honeywell ABP pressure sensors.
- New driver covering 56 parts in this series (too many to list here!)
* HTS221
- New driver to support this relative humidiy and temperature device.
* LMP91000
- New driver for this potentiostat (form of chemical sensor). Nice example
of use of the buffered consumer interfaces and the use of a consumer
provided trigger.
* MiraMEMS DA311
- New driver for this 3 axis accelerometer.
* MiraMEMS DA280
- New driver for this 3 axis accelerometer. Follow up caught up with
vendor prefixes for these.
Staging graduations
* isl29018 light sensor
- Fixes and cleanups listed below (thanks for your hard work on this Brian!)
* sca3000
- Fixes and cleanups listed below. This was one of the small set of drivers
that went into staging when IIO was first added. Turns out it had a few
bugs and needed to be brought into the modern era! Not clear if I am
the only person who actually has one of these still wired to a board.
New features (Core)
- Add an iio_trigger_validate_own_device helper which relies on the device
and trigger having the same parent. Convenient to have this for some
of the more complex trigger / device interactions. Was hand rolled in
a few drivers already so good to bring it into the core.
- Add an iio_read_channel_offset in kernel access helper (similar to
the existing one for scale).
- IIO_ATTR_{RO, WO, RW} and IIO_DEVICE_ATTR_{RO, WO, RW} macros. These
lead some rather contrived function naming, but there is no denying they
do reduced boilerplate. I'm going to resist their introduction in
drivers 'unless' they form part of a larger set of cleanups.
- Counter channel type and index type.
New features (Drivers)
* hdc100x
- Triggered buffer support.
* mcp4725
- Device tree bindings and support.
- Voltage reference selection.
* ti-adc0832
- Triggered buffer support.
* ti-adc161s626
- Add regulator support allowing _scale and _offset values to be established
and exported.
New features (Tools)
* iio_generic_buffer
- -A option to force enable all channels rather than faulting if some are
already enabled (like -a does). Followup patches tidied this support up.
Cleanups (Core)
- Use kmalloc_array in iio_scan_mask_set.
- Take event_attrs field of iio_info structure constant
- Staging todo list updates. Most of it was long done.
- MAINTAINERS had a wrong directory listing.
Cleanups (Drivers)
* Missing i2c trivial devices entries.
* ad5592r
- Fix an endian type related sparse warnings.
* ad7150
- Constify the event attribute_group structures.
* ad7152
- Add some blank lines to improve readability.
- Sampling frequency control via chan-info element rather than hand rolled
attributes.
- add a new lock to avoid use of mlock for non state change related locking.
* ad7280
- Constify atrribute_group structure (second patch covers the event ones)
* ad7606 (Lars is driving most of the cleanup on this with some additions from
Eva)
- Fix improper setting of oversampling pins. This has been broken a very
long time in this staging driver, so not going to push this back to stable.
- Implement oversampling configuration via the chan_info mask element.
- Remove an unused int_vref_mv field.
- Remove a reundant name field from ad7606_chip_info.
- Remove default device configuration from platform_data in favour of
whatever the power on defaults are.
- Remove out of band error reporting in the kernel log as not providing
much information.
- Fix oversampling ratio by having 1 be the value for no oversampling.
- Avoid allocating buffer for each data capture.
- Factor out common code between periodic and one-shot capture.
- Move set_drvdat into common code.
- Let the common probe function return int rather than jumping through
an ERR_PTR.
- Pass struct device * into common remove to simplify code.
- Always run trigger handler only once per event (no one can remember why
it was being possibly done twice).
- Move over to the GPIO descriptor API to shorten and clarify code.
- Move the buffer code into the main file as it's not optional and is
now rather short in this driver.
- Fix the naming of the supply regulator.
- Rework regulator handling to handle errors including deferred probing.
- Tidy up a ptr_err or 0 return.
* ad7746
- Sampling frequency control via info_mask element rather than hand rolled
* ad7758
- Sampling frequency control via info_mask element rather than hand rolled
attributes.
* ad7816
- Constify the event attribute_group structure.
* adt7316
- Constify the event attribute group structures.
* ak8974
- Cleanup some sparse warnings about endian types.
* ak8975
- Cleanup some sparse warnings about endian types.
* bmi160
- Spare endian warning cleanups.
* isl29018 (towards staging graduation)
- Remove unusedvariables and defines.
- Improve consistency of error handling.
- Signed / unsigned comparison fixes.
- Use the IIO_DEVICE_ATTR_{RO, RW} macros
- Fix a race in in_illuminance_scale_available_show.
- Cleanup exit points of _read_raw
- Sanity check if in suspended state during a write_raw call as was already
done for read_raw.
- Document device tree bidnings.
- Document infrared supression controls.
- Add some newlines to improve readability and drop one that shouldn't be
there.
- Fix a poorly named functions name.
- Fix multiline coment syntax.
- Tidy up a pair or return statements by unifying them.
- Rename description in Kconfig for consistency with similar drivers.
* lidar
- cleanup power management by dropping unnecessary call.
* ltr501
- Use the claim_direct_mode helpers. Fix a race condition along the way.
* max1027
- Fix a dubious x | !y sparse warning.
- Use the new iio_trigger_validate_own_device helper.
* max440000
- Clean up some sparse warnings about endian types.
* mcp4725
- Use the regulator framework to establish the reference voltage rather than
getting it from platform data.
- Tidy up a comment typo.
- Fix a wrong PTR_ERR query (wrong regulator).
* mma7660
- Take a mma7660_nscale static.
* mma8452
- Use the new iio_trigger_validate_own_device helper.
- Use claim_direct_mode helpers - fix a race condition along the way.
* mpl3115
- Use claim_direct_mode helpers - fix a race condition along the way.
* ms65611
- Tidy up regulator error handling and clean out a static warning in the mix.
* sca3000
- Avoid a potential unitialized variable if a hardware read returns a value
that isn't actually supported (mostly warning supression).
- Fix a use before setting of the indio_dev->buffer pointer. Broken for
a very long time so not going to rush this into stable.
- Merge buffer file with core file. We used to always split these.
Sometimes it's just not worth the hassle. In this case the device's main
feature is it's hardware fifos so unlikely anyone would want to run it
without.
- Drop the sca3000_register_ring_funcs function as it's a pointless wrapper
once we have only one file.
- Fix cleaning of flag + setting of size of scan. Without this you can't
start the buffer twice and expect sensible (or any) results. Again,
broken for a long time so not heading for stable.
- Drop the custom watershed setting ABI - for now we'll just support one
value.
- Move to a hybrid hard / soft buffer design (how we've been doing it
for similar devices for a while now!)
- Cleanup some unusued variables.
- Use a fake channel to support core handling of freefall event registration.
- Cleanup the register defines.
- Fix an off by one error in axis due to IIO_NO_MOD taking up the 0 value.
Been broken since first admission of IIO to the staging tree.
- Add readback of the 3db low pass filter frequency and later writing
allowing droppign of custom measurement mode attributes as they can
be represented by the filter choices that is their main characteristic.
- Drop non standard revision attr and replace with dev_info on probe.
- Avoid a race in probe.
- Various formatting fixes.
- Kernel-docify docs that were very nearly in the write format.
* tsl2583
- Constify attribute_group structure.
* zpa2326
- Drop a redundant DEBUG ifdef.
Cleanups (Tools)
* iio_generic_buffer
- Fix the ? arguement. Previously it sort of worked as you got the help
message as a result of it not recognising the arguement.

In criu we are actively using diag interface to collect sockets
present in the system when dumping applications. And while for
unix, tcp, udp[lite], packet, netlink it works as expected,
the raw sockets do not have. Thus add it.
v2:
- add missing sock_put calls in raw_diag_dump_one (by eric.dumazet@)
- implement @destroy for diag requests (by dsa@)
v3:
- add export of raw_abort for IPv6 (by dsa@)
- pass net-admin flag into inet_sk_diag_fill due to
changes in net-next branch (by dsa@)
v4:
- use @pad in struct inet_diag_req_v2 for raw socket
protocol specification: raw module carries sockets
which may have custom protocol passed from socket()
syscall and sole @sdiag_protocol is not enough to
match underlied ones
- start reporting protocol specifed in socket() call
when sockets are raw ones for the same reason: user
space tools like ss may parse this attribute and use
it for socket matching
v5 (by eric.dumazet@):
- use sock_hold in raw_sock_get instead of atomic_inc,
we're holding (raw_v4_hashinfo|raw_v6_hashinfo)->lock
when looking up so counter won't be zero here.
v6:
- use sdiag_raw_protocol() helper which will access @pad
structure used for raw sockets protocol specification:
we can't simply rename this member without breaking uapi
v7:
- sine sdiag_raw_protocol() helper is not suitable for
uapi lets rather make an alias structure with proper
names. __check_inet_diag_req_raw helper will catch
if any of structure unintentionally changed.

These formats store the color information of the image
in a geometrical representation. The colors are mapped into a
cylinder, where the angle is the HUE, the height is the VALUE
and the distance to the center is the SATURATION. This is a very

Somehow, I missed a healthy number of ethernet drivers in the last pass.
Most of these drivers either were in need of an updated max_mtu to make
jumbo frames possible to enable again. In a few cases, also setting a
different min_mtu to match previous lower bounds. There are also a few
drivers that had no upper bounds checking, so they're getting a brand new

fix them before actually submitting them. That technique worked,
but later than I would have liked.

Pull XFS support for shared data extents from Dave Chinner:
"This is the second part of the XFS updates for this merge cycle. This
pullreq contains the new shared data extents feature for XFS.
Given the complexity and size of this change I am expecting - like the
addition of reverse mapping last cycle - that there will be some
follow-up bug fixes and cleanups around the -rc3 stage for issues that
I'm sure will show up once the code hits a wider userbase.
What it is:
At the most basic level we are simply adding shared data extents to
XFS - i.e. a single extent on disk can now have multiple owners. To do
this we have to add new on-disk features to both track the shared
extents and the number of times they've been shared. This is done by
the new "refcount" btree that sits in every allocation group. When we
share or unshare an extent, this tree gets updated.
Along with this new tree, the reverse mapping tree needs to be updated
to track each owner or a shared extent. This also needs to be updated
ever share/unshare operation. These interactions at extent allocation
and freeing time have complex ordering and recovery constraints, so
there's a significant amount of new intent-based transaction code to
ensure that operations are performed atomically from both the runtime
and integrity/crash recovery perspectives.
We also need to break sharing when writes hit a shared extent - this
is where the new copy-on-write implementation comes in. We allocate
new storage and copy the original data along with the overwrite data
into the new location. We only do this for data as we don't share
metadata at all - each inode has it's own metadata that tracks the
shared data extents, the extents undergoing CoW and it's own private
extents.
Of course, being XFS, nothing is simple - we use delayed allocation
for CoW similar to how we use it for normal writes. ENOSPC is a
significant issue here - we build on the reservation code added in
4.8-rc1 with the reverse mapping feature to ensure we don't get
spurious ENOSPC issues part way through a CoW operation. These
mechanisms also help minimise fragmentation due to repeated CoW
operations. To further reduce fragmentation overhead, we've also
introduced a CoW extent size hint, which indicates how large a region
we should allocate when we execute a CoW operation.
With all this functionality in place, we can hook up .copy_file_range,
.clone_file_range and .dedupe_file_range and we gain all the
capabilities of reflink and other vfs provided functionality that
enable manipulation to shared extents. We also added a fallocate mode
that explicitly unshares a range of a file, which we implemented as an
explicit CoW of all the shared extents in a file.
As such, it's a huge chunk of new functionality with new on-disk
format features and internal infrastructure. It warns at mount time as
an experimental feature and that it may eat data (as we do with all
new on-disk features until they stabilise). We have not released
userspace suport for it yet - userspace support currently requires
download from Darrick's xfsprogs repo and build from source, so the
access to this feature is really developer/tester only at this point.
Initial userspace support will be released at the same time the kernel
with this code in it is released.
The new code causes 5-6 new failures with xfstests - these aren't
serious functional failures but things the output of tests changing
slightly due to perturbations in layouts, space usage, etc. OTOH,
we've added 150+ new tests to xfstests that specifically exercise this
new functionality so it's got far better test coverage than any
functionality we've previously added to XFS.
Darrick has done a pretty amazing job getting us to this stage, and
special mention also needs to go to Christoph (review, testing,
improvements and bug fixes) and Brian (caught several intricate bugs
during review) for the effort they've also put in.
Summary:
- unshare range (FALLOC_FL_UNSHARE) support for fallocate
- copy-on-write extent size hints (FS_XFLAG_COWEXTSIZE) for fsxattr
interface
- shared extent support for XFS
- copy-on-write support for shared extents

With centralized MTU checking, there's nothing productive done by
eth_change_mtu that isn't already done in dev_set_mtu, so mark it as
deprecated and remove all usage of it in the kernel. All callers have been
audited for calls to alloc_etherdev* or ether_setup directly, which means
they all have a valid dev->min_mtu and dev->max_mtu. Now eth_change_mtu
prints out a netdev_warn about being deprecated, for the benefit of
out-of-tree drivers that might be utilizing it.
Of note, dvb_net.c actually had dev->mtu = 4096, while using
eth_change_mtu, meaning that if you ever tried changing it's mtu, you
couldn't set it above 1500 anymore. It's now getting dev->max_mtu also set
to 4096 to remedy that.

This commit provides a mechanism for the host drivers to advertise the
support for different beacon intervals among the respective interface
combinations in a group, through NL80211_IFACE_COMB_BI_MIN_GCD (u32).
This value will be compared against GCD of all beaconing interfaces of
matching combinations.
If the driver doesn't advertise this value, the old behaviour where
all beacon intervals must be identical is retained.
If it is specified, then any beacon interval for an interface in the
interface combination as well as the GCD of all active beacon intervals
in the combination must be greater or equal to this value.

* PMEM sub-division support: Allow a single PMEM region to be divided
into multiple namespaces. Originally, ~2 years ago, it was thought that
partitions of a /dev/pmemX block device could handle sub-allocations of
persistent memory for different use cases. With the decision to not
support DAX mappings of raw block-devices, and the genesis of
device-dax, the need for having multiple pmem-namespace per region has
grown.
* Device-DAX unified inode: In support of dynamic-resizing of a
device-dax instance the kernel arranges for all mappings of a
device-dax node to share the same inode. This allows unmap / truncate /
invalidation events to affect all instances of the device similar to the
behavior of mmap on block devices.
* Hardware error scrubbing reworks: The original address-range-scrub +
badblocks tracking solution allowed clearing entries at the individual
namespace level, but it failed to clear the internal list of media
errors maintained at the bus level. The result was that the next scrub
or namespace disable/re-enable event would restore the cleared
badblocks, but now that is fixed. The v4.8 kernel introduced an
auto-scrub-on-machine-check behavior to repopulate the badblocks list.
Now, in v4.9, the auto-scrub behavior can be disabled and simply arrange
for the error reported in the machine-check to be added to the list.
* DIMM health-event notification support: ACPI 6.1 defines a
notification event code that can be send to ACPI NVDIMM devices. A
poll(2) capable file descriptor for these events can be obtained from
the nmemX/nfit/flags sysfs-attribute of a libnvdimm memory device.
* Miscellaneous fixes: NVDIMM-N probe error, device-dax build error, and
a change to dedup the flush hint list to not flush the memory controller
more than necessary.

Pull libnvdimm updates from Dan Williams:
"Aside from the recently added pmem sub-division support these have
been in -next for several releases with no reported issues. The sub-
division support was included in next-20161010 with no reported
issues. It passes all unit tests including new tests for all the new
functionality below.
Summary:
- PMEM sub-division support: Allow a single PMEM region to be divided
into multiple namespaces. Originally, ~2 years ago, it was thought

We had inserted a #error into the topology UAPI code to ensure that the
ABI was not adopted by userspace while final review and testing was
ongoing. The idea was that some finishing touches would be made to the
ABI before declaring it stable and suitable for use in production but
this has not yet happened as more than a year later revisions to the ABI
are still onging.
The reality however is that people are shipping topology files in
production and these ABI changes are causing practical issues for users
and we can't break userspace. This makes this error pointless so we
should remove it.
