UVC defines a method of handling asynchronous controls, which sends a
USB packet over the interrupt pipe. This patch implements support for
such packets by sending a control event to the user. Since this can
involve USB traffic and, therefore, scheduling, this has to be done
in a work queue.

The use of 'DTV' is very confusing since it normally refers to Digital
TV e.g. DVB etc.
Instead use 'DV' (Digital Video), which nicely corresponds to the
DV Timings API used to configure such receivers and transmitters.
We keep an alias to avoid breaking userspace applications.
Since this alias is only available if __KERNEL__ is *not* defined
(i.e. it is only available for userspace, not kernelspace), any
drivers that use it also have to be converted to the new define.
These drivers are adv7604, adv7842 and tda1997x.

And where the previous unwinder only needed BP,SP ORC also requires
IP. But we cannot spoof IP because then the sample will get displaced,
entirely negating the point of PEBS.
So cure the whole thing differently by doing the unwind early; this
does however require a means to communicate we did the unwind early.
We (ab)use an unused sample_type bit for this, which we set on events
that fill out the data->callchain before the normal
perf_prepare_sample().

Skbprio (SKB Priority Queue) is a queueing discipline that prioritizes packets
according to their skb->priority field. Under congestion, already-enqueued lower
priority packets will be dropped to make space available for higher priority
packets. Skbprio was conceived as a solution for denial-of-service defenses that
need to route packets with different priorities as a means to overcome DoS
attacks.

*Drop max_limit parameter in struct skbprio_sched_data and instead use

*Reference qdisc_dev(sch)->tx_queue_len only once, during initialisation for
qdisc (previously being referenced every time qdisc changes).
*Move qdisc's detailed description from in-code to Documentation/networking.
*When qdisc is saturated, enqueue incoming packet first before dequeueing
lowest priority packet in queue - improves usage of call stack registers.
*Introduce and use overlimit stat to keep track of number of dropped packets.
v2
*Use skb->priority field rather than DS field. Rename queueing discipline as
SKB Priority Queue (previously Gatekeeper Priority Queue).
*Queueing discipline is made classful to expose Skbprio's internal priority
queues.

There are many data structures (RDS socket options) used by RDS apps
which use a 32 bit integer to store IP address. To support IPv6,
struct in6_addr needs to be used. To ensure backward compatibility, a
new data structure is introduced for each of those data structures
which use a 32 bit integer to represent an IP address. And new socket
options are introduced to use those new structures. This means that
existing apps should work without a problem with the new RDS module.
For apps which want to use IPv6, those new data structures and socket
options can be used. IPv4 mapped address is used to represent IPv4
address in the new data structures.

This patch adds a new port attribute - IFLA_BRPORT_BACKUP_PORT, which
allows to set a backup port to be used for known unicast traffic if the
port has gone carrier down. The backup pointer is rcu protected and set
only under RTNL, a counter is maintained so when deleting a port we know
how many other ports reference it as a backup and we remove it from all.
Also the pointer is in the first cache line which is hot at the time of
the check and thus in the common case we only add one more test.
The backup port will be used only for the non-flooding case since
it's a part of the bridge and the flooded packets will be forwarded to it
anyway. To remove the forwarding just send a 0/non-existing backup port.
This is used to avoid numerous scalability problems when using MLAG most
notably if we have thousands of fdbs one would need to change all of them
on port carrier going down which takes too long and causes a storm of fdb
notifications (and again when the port comes back up). In a Multi-chassis
Link Aggregation setup usually hosts are connected to two different
switches which act as a single logical switch. Those switches usually have
a control and backup link between them called peerlink which might be used
for communication in case a host loses connectivity to one of them.
We need a fast way to failover in case a host port goes down and currently
none of the solutions (like bond) cannot fulfill the requirements because
the participating ports are actually the "master" devices and must have the
same peerlink as their backup interface and at the same time all of them
must participate in the bridge device. As Roopa noted it's normal practice
in routing called fast re-route where a precalculated backup path is used
when the main one is down.
Another use case of this is with EVPN, having a single vxlan device which
is backup of every port. Due to the nature of master devices it's not
currently possible to use one device as a backup for many and still have
all of them participate in the bridge (which is master itself).
More detailed information about MLAG is available at the link below.
https://docs.cumulusnetworks.com/display/DOCS/Multi-Chassis+Link+Aggregation+-+MLAG
Further explanation and a diagram by Roopa:
Two switches acting in a MLAG pair are connected by the peerlink
interface which is a bridge port.
the config on one of the switches looks like the below. The other
switch also has a similar config.
eth0 is connected to one port on the server. And the server is
connected to both switches.

Add ioctls USBTMC_IOCTL_GET_TIMEOUT / USBTMC_IOCTL_SET_TIMEOUT to
get/set I/O timeout for specific file handle.
Different operations on an instrument can take different lengths of
time thus it is important to be able to set the timeout slightly
longer than the expected duration of each operation to optimise the
responsiveness of the application. As the instrument may be shared by
multiple applications the timeout should be settable on a per file
descriptor basis.

This patch shrinks the BTF_INT_BITS() mask. The current
btf_int_check_meta() ensures the nr_bits of an integer
cannot exceed 64. Hence, it is mostly an uapi cleanup.
The actual btf usage (i.e. seq_show()) is also modified
to use u8 instead of u16. The verification (e.g. btf_int_check_meta())
path stays as is to deal with invalid BTF situation.

Define an NT_MIPS_DSP core file note type and implement a corresponding
regset holding the DSP ASE register context, following the layout of the
`mips_dsp_state' structure, except for the DSPControl register stored as
a 64-bit rather than 32-bit quantity in a 64-bit note.
The lack of DSP ASE register saving to core files can be considered a
design flaw with commit e50c0a8fa6 ("Support the MIPS32 / MIPS64 DSP
ASE."), leading to an incomplete state being saved. Consequently no DSP
ASE regset has been created with commit 7aeb753b53 ("MIPS: Implement
task_user_regset_view."), when regset support was added to the MIPS
port.
Additionally there is no way for ptrace(2) to correctly access the DSP
accumulator registers in n32 processes with the existing interfaces.
This is due to 32-bit truncation of data passed with PTRACE_PEEKUSR and
PTRACE_POKEUSR requests, which cannot be avoided owing to how the data
types for ptrace(3) have been defined. This new NT_MIPS_DSP regset
fills the missing interface gap.

introduced by commit 2724273e8f ("vmcore: add API to collect

be considered a flaw in earlier DSP ASE support, it's still new
functionality which doesn't meet up to the requirements set out in

Add new TCP-BPF callback that is called on listen(2) right after socket
transition to TCP_LISTEN state.
It fills the gap for listening sockets in TCP-BPF. For example BPF
program can set BPF_SOCK_OPS_STATE_CB_FLAG when socket becomes listening
and track later transition from TCP_LISTEN to TCP_CLOSE with
BPF_SOCK_OPS_STATE_CB callback.
Before there was no way to do it with TCP-BPF and other options were
much harder to work with. E.g. socket state tracking can be done with
tracepoints (either raw or regular) but they can't be attached to cgroup
and their lifetime has to be managed separately.

This patch adds support for IGMPMSG_WRVIFWHOLE which is used to pass
full packet and real vif id when the incoming interface is wrong.
While the RP and FHR are setting up state we need to be sending the
registers encapsulated with all the data inside otherwise we lose it.
The RP then decapsulates it and forwards it to the interested parties.
Currently with WRONGVIF we can only be sending empty register packets
and will lose that data.
This behaviour can be enabled by using MRT_PIM with
val == IGMPMSG_WRVIFWHOLE. This doesn't prevent IGMPMSG_WRONGVIF from
happening, it happens in addition to it, also it is controlled by the same
throttling parameters as WRONGVIF (i.e. 1 packet per 3 seconds currently).
Both messages are generated to keep backwards compatibily and avoid
breaking someone who was enabling MRT_PIM with val == 4, since any
positive val is accepted and treated the same.

sch_cake targets the home router use case and is intended to squeeze the
most bandwidth and latency out of even the slowest ISP links and routers,
while presenting an API simple enough that even an ISP can configure it.
Example of use on a cable ISP uplink:
tc qdisc add dev eth0 cake bandwidth 20Mbit nat docsis ack-filter
To shape a cable download link (ifb and tc-mirred setup elided)
tc qdisc add dev ifb0 cake bandwidth 200mbit nat docsis ingress wash
CAKE is filled with:
* A hybrid Codel/Blue AQM algorithm, "Cobalt", tied to an FQ_Codel
derived Flow Queuing system, which autoconfigures based on the bandwidth.
* A novel "triple-isolate" mode (the default) which balances per-host
and per-flow FQ even through NAT.
* An deficit based shaper, that can also be used in an unlimited mode.
* 8 way set associative hashing to reduce flow collisions to a minimum.
* A reasonable interpretation of various diffserv latency/loss tradeoffs.
* Support for zeroing diffserv markings for entering and exiting traffic.
* Support for interacting well with Docsis 3.0 shaper framing.
* Extensive support for DSL framing types.
* Support for ack filtering.
* Extensive statistics for measuring, loss, ecn markings, latency
variation.
A paper describing the design of CAKE is available at
https://arxiv.org/abs/1804.07617, and will be published at the 2018 IEEE
International Symposium on Local and Metropolitan Area Networks (LANMAN).
This patch adds the base shaper and packet scheduler, while subsequent
commits add the optional (configurable) features. The full userspace API
and most data structures are included in this commit, but options not
understood in the base version will be ignored.
Various versions baking have been available as an out of tree build for
kernel versions going back to 3.10, as the embedded router world has been
running a few years behind mainline Linux. A stable version has been
generally available on lede-17.01 and later.
sch_cake replaces a combination of iptables, tc filter, htb and fq_codel
in the sqm-scripts, with sane defaults and vastly simpler configuration.
CAKE's principal author is Jonathan Morton, with contributions from
Kevin Darbyshire-Bryant, Toke Høiland-Jørgensen, Sebastian Moeller,
Ryan Mounce, Tony Ambardar, Dean Scarff, Nils Andreas Svee, Dave Täht,
and Loganaden Velvindron.

Declaring the rseq_cs field as a union between __u64 and two __u32
allows both 32-bit and 64-bit kernels to read the full __u64, and
therefore validate that a 32-bit user-space cleared the upper 32
bits, thus ensuring a consistent behavior between native 32-bit
kernels and 32-bit compat tasks on 64-bit kernels.
Check that the rseq_cs value read is < TASK_SIZE.
The asm/byteorder.h header needs to be included by rseq.h, now
that it is not using linux/types_32_64.h anymore.
Considering that only __32 and __u64 types are declared in linux/rseq.h,
the linux/types.h header should always be included for both kernel and
user-space code: including stdint.h is just for u64 and u32, which are
not used in this header at all.
Use copy_from_user()/clear_user() to interact with a 64-bit field,
because arm32 does not implement 64-bit __get_user, and ppc32 does not
64-bit get_user. Considering that the rseq_cs pointer does not need to
be loaded/stored with single-copy atomicity from the kernel anymore, we
can simply use copy_from_user()/clear_user().

Change the rseq ABI so rseq_cs start_ip, post_commit_offset and abort_ip
fields are seen as 64-bit fields by both 32-bit and 64-bit kernels rather
that ignoring the 32 upper bits on 32-bit kernels. This ensures we have a
consistent behavior for a 32-bit binary executed on 32-bit kernels and in
compat mode on 64-bit kernels.
Validating the value of abort_ip field to be below TASK_SIZE ensures the
kernel don't return to an invalid address when returning to userspace
after an abort. I don't fully trust each architecture code to consistently
deal with invalid return addresses.
Validating the value of the start_ip and post_commit_offset fields
prevents overflow on arithmetic performed on those values, used to
check whether abort_ip is within the rseq critical section.
If validation fails, the process is killed with a segmentation fault.
When the signature encountered before abort_ip does not match the expected
signature, return -EINVAL rather than -EPERM to be consistent with other
input validation return codes from rseq_get_rseq_cs().

Use the socket error queue for reporting dropped packets if the
socket has enabled that feature through the SO_TXTIME API.
Packets are dropped either on enqueue() if they aren't accepted by the
qdisc or on dequeue() if the system misses their deadline. Those are
reported as different errors so applications can react accordingly.
Userspace can retrieve the errors through the socket error queue and the
corresponding cmsg interfaces. A struct sock_extended_err* is used for
returning the error data, and the packet's timestamp can be retrieved by
adding both ee_data and ee_info fields as e.g.:
((__u64) serr->ee_data << 32) + serr->ee_info
This feature is disabled by default and must be explicitly enabled by
applications. Enabling it can bring some overhead for the Tx cycles
of the application.

Add infra so etf qdisc supports HW offload of time-based transmission.
For hw offload, the time sorted list is still used, so packets are
dequeued always in order of txtime.
Example:
$ tc qdisc replace dev enp2s0 parent root handle 100 mqprio num_tc 3 \
map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 queues 1@0 1@1 2@2 hw 0
$ tc qdisc add dev enp2s0 parent 100:1 etf offload delta 100000 \
clockid CLOCK_REALTIME
In this example, the Qdisc will use HW offload for the control of the
transmission time through the network adapter. The hrtimer used for
packets scheduling inside the qdisc will use the clockid CLOCK_REALTIME
as reference and packets leave the Qdisc "delta" (100000) nanoseconds
before their transmission time. Because this will be using HW offload and
since dynamic clocks are not supported by the hrtimer, the system clock
and the PHC clock must be synchronized for this mode to behave as
expected.

The ETF (Earliest TxTime First) qdisc uses the information added
earlier in this series (the socket option SO_TXTIME and the new
role of sk_buff->tstamp) to schedule packets transmission based
on absolute time.
For some workloads, just bandwidth enforcement is not enough, and
precise control of the transmission of packets is necessary.
Example:
$ tc qdisc replace dev enp2s0 parent root handle 100 mqprio num_tc 3 \
map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 queues 1@0 1@1 2@2 hw 0
$ tc qdisc add dev enp2s0 parent 100:1 etf delta 100000 \
clockid CLOCK_TAI
In this example, the Qdisc will provide SW best-effort for the control
of the transmission time to the network adapter, the time stamp in the
socket will be in reference to the clockid CLOCK_TAI and packets
will leave the qdisc "delta" (100000) nanoseconds before its transmission
time.
The ETF qdisc will buffer packets sorted by their txtime. It will drop
packets on enqueue() if their skbuff clockid does not match the clock
reference of the Qdisc. Moreover, on dequeue(), a packet will be dropped
if it expires while being enqueued.
The qdisc also supports the SO_TXTIME deadline mode. For this mode, it
will dequeue a packet as soon as possible and change the skb timestamp
to 'now' during etf_dequeue().
Note that both the qdisc's and the SO_TXTIME ABIs allow for a clockid
to be configured, but it's been decided that usage of CLOCK_TAI should
be enforced until we decide to allow for other clockids to be used.
The rationale here is that PTP times are usually in the TAI scale, thus
no other clocks should be necessary. For now, the qdisc will return
EINVAL if any clocks other than CLOCK_TAI are used.

struct sock_txtime {

};
Note that new fields were added to struct sock by filling a 2-bytes

Add a menu control V4L2_CID_MPEG_VIDEO_VP8_PROFILE for VP8 profile and make
V4L2_CID_MPEG_VIDEO_VPX_PROFILE an alias of it. This new control is used to
select the desired profile for VP8 encoder and query for supported profiles by
VP8 encoder/decoder.
Though we have originally a control V4L2_CID_MPEG_VIDEO_VPX_PROFILE and its name
contains 'VPX', it works only for VP8 because supported profiles usually differ
between VP8 and VP9. In addition, this control cannot be used for querying since
it is not a menu control but an integer control, which cannot return an
arbitrary set of supported profiles.
The new control V4L2_CID_MPEG_VIDEO_VP8_PROFILE is a menu control as with
controls for other codec profiles. (e.g. H264)
In addition, this patch also fixes the use of V4L2_CID_MPEG_VIDEO_VPX_PROFILE in

spp_ipv6_flowlabel and spp_dscp are added in sctp_paddrparams in
this patch so that users could set sctp_sock/asoc/transport dscp
and flowlabel with spp_flags SPP_IPV6_FLOWLABEL or SPP_DSCP by
SCTP_PEER_ADDR_PARAMS , as described section 8.1.12 in RFC6458.
As said in last patch, it uses '| 0x100000' or '|0x1' to mark
flowlabel or dscp is set, so that their values could be set
to 0.
Note that to guarantee that an old app built with old kernel
headers could work on the newer kernel, the param's check in
sctp_g/setsockopt_peer_addr_params() is also improved, which
follows the way that sctp_g/setsockopt_delayed_ack() or some
other sockopts' process that accept two types of params does.

pull-request: bpf 2018-07-01
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) A bpf_fib_lookup() helper fix to change the API before freeze to
return an encoding of the FIB lookup result and return the nexthop
device index in the params struct (instead of device index as return
code that we had before), from David.
2) Various BPF JIT fixes to address syzkaller fallout, that is, do not
reject progs when set_memory_*() fails since it could still be RO.
Also arm32 JIT was not using bpf_jit_binary_lock_ro() API which was
an issue, and a memory leak in s390 JIT found during review, from
Daniel.
3) Multiple fixes for sockmap/hash to address most of the syzkaller
triggered bugs. Usage with IPv6 was crashing, a GPF in bpf_tcp_close(),
a missing sock_map_release() routine to hook up to callbacks, and a
fix for an omitted bucket lock in sock_close(), from John.
4) Two bpftool fixes to remove duplicated error message on program load,
and another one to close the libbpf object after program load. One
additional fix for nfp driver's BPF offload to avoid stopping offload
completely if replace of program failed, from Jakub.
5) Couple of BPF selftest fixes that bail out in some of the test
scripts if the user does not have the right privileges, from Jeffrin.
6) Fixes in test_bpf for s390 when CONFIG_BPF_JIT_ALWAYS_ON is set
where we need to set the flag that some of the test cases are expected
to fail, from Kleber.
7) Fix to detangle BPF_LIRC_MODE2 dependency from CONFIG_CGROUP_BPF
since it has no relation to it and lirc2 users often have configs
without cgroups enabled and thus would not be able to use it, from Sean.
8) Fix a selftest failure in sockmap by removing a useless setrlimit()
call that would set a too low limit where at the same time we are
already including bpf_rlimit.h that does the job, from Yonghong.
9) Fix BPF selftest config with missing missing NET_SCHED, from Anders.

A PCIe endpoint carries the process address space identifier (PASID) in
the TLP prefix as part of the memory read/write transaction. The address
information in the TLP is relevant only for a given PASID context.
An IOMMU takes PASID value and the address information from the
TLP to look up the physical address in the system.
PASID is an End-End TLP Prefix (PCIe r4.0, sec 6.20). Sec 2.2.10.2 says
It is an error to receive a TLP with an End-End TLP Prefix by a
Receiver that does not support End-End TLP Prefixes. A TLP in
violation of this rule is handled as a Malformed TLP. This is a
reported error associated with the Receiving Port (see Section 6.2).
Prevent error condition by proactively requiring End-End TLP prefix to be
supported on the entire data path between the endpoint and the root port
before enabling PASID.

This feature is actually already supported by sk->sk_reuse which can be
set by socket level opt SO_REUSEADDR. But it's not working exactly as
RFC6458 demands in section 8.1.27, like:
- This option only supports one-to-one style SCTP sockets
- This socket option must not be used after calling bind()
or sctp_bindx().
Besides, SCTP_REUSE_PORT sockopt should be provided for user's programs.
Otherwise, the programs with SCTP_REUSE_PORT from other systems will not
work in linux.
To separate it from the socket level version, this patch adds 'reuse' in
sctp_sock and it works pretty much as sk->sk_reuse, but with some extra
setup limitations that are needed when it is being enabled.
"It should be noted that the behavior of the socket-level socket option
to reuse ports and/or addresses for SCTP sockets is unspecified", so it
leaves SO_REUSEADDR as is for the compatibility.
Note that the name SCTP_REUSE_PORT is somewhat confusing, as its
functionality is nearly identical to SO_REUSEADDR, but with some
extra restrictions. Here it uses 'reuse' in sctp_sock instead of
'reuseport'. As for sk->sk_reuseport support for SCTP, it will be
added in another patch.
Thanks to Neil to make this clear.
v1->v2:
- add sctp_sk->reuse to separate it from the socket level version.
v2->v3:
- improve changelog according to Marcelo's suggestion.

For ACLs implemented using either FIB rules or FIB entries, the BPF
program needs the FIB lookup status to be able to drop the packet.
Since the bpf_fib_lookup API has not reached a released kernel yet,
change the return code to contain an encoding of the FIB lookup
result and return the nexthop device index in the params struct.
In addition, inform the BPF program of any post FIB lookup reason as
to why the packet needs to go up the stack.
The fib result for unicast routes must have an egress device, so remove
the check that it is non-NULL.

The poll() changes were not well thought out, and completely
unexplained. They also caused a huge performance regression, because
"->poll()" was no longer a trivial file operation that just called down
to the underlying file operations, but instead did at least two indirect
calls.
Indirect calls are sadly slow now with the Spectre mitigation, but the
performance problem could at least be largely mitigated by changing the
"->get_poll_head()" operation to just have a per-file-descriptor pointer
to the poll head instead. That gets rid of one of the new indirections.
But that doesn't fix the new complexity that is completely unwarranted
for the regular case. The (undocumented) reason for the poll() changes
was some alleged AIO poll race fixing, but we don't make the common case
slower and more complex for some uncommon special case, so this all
really needs way more explanations and most likely a fundamental
redesign.

Extend slotting with support for non-uniform distributions. This is
similar to netem's non-uniform distribution delay feature.
Commit f043efeae2f1 ("netem: support delivering packets in delayed
time slots") added the slotting feature to approximate the behaviors
of media with packet aggregation but only supported a uniform
distribution for delays between transmission attempts. Tests with TCP
BBR with emulated wifi links with non-uniform distributions produced
more useful results.
Syntax:
slot dist DISTRIBUTION DELAY JITTER [packets MAX_PACKETS] \
[bytes MAX_BYTES]
The syntax and use of the distribution table is the same as in the
non-uniform distribution delay feature. A file DISTRIBUTION must be
present in TC_LIB_DIR (e.g. /usr/lib/tc) containing numbers scaled by
NETEM_DIST_SCALE. A random value x is selected from the table and it
takes DELAY + ( x * JITTER ) as delay. Correlation between values is not
supported.
Examples:
Normal distribution delay with mean = 800us and stdev = 100us.
> tc qdisc add dev eth0 root netem slot dist normal 800us 100us
Optionally set the max slot size in bytes and/or packets.
> tc qdisc add dev eth0 root netem slot dist normal 800us 100us \
bytes 64k packets 42

The flag IN_MASK_CREATE is introduced as a flag for inotiy_add_watch()
which prevents inotify from modifying any existing watches when invoked.
If the pathname specified in the call has a watched inode associated
with it and IN_MASK_CREATE is specified, fail with an errno of EEXIST.
Use of IN_MASK_CREATE with IN_MASK_ADD is reserved for future use and
will return EINVAL.
RATIONALE
In the current implementation, there is no way to prevent
inotify_add_watch() from modifying existing watch descriptors. Even if
the caller keeps a record of all watch descriptors collected, this is
only sufficient to detect that an existing watch descriptor may have
been modified.
The assumption that a particular path will map to the same inode over
multiple calls to inotify_add_watch() cannot be made as files can be
renamed or deleted. It is also not possible to assume that two distinct
paths do no map to the same inode, due to hard-links or a dereferenced
symbolic link. Further uses of inotify_add_watch() to revert the change
may cause other watch descriptors to be modified or created, merely
compunding the problem. There is currently no system call such as
inotify_modify_watch() to explicity modify a watch descriptor, which
would be able to revert unwanted changes. Thus the caller cannot
guarantee to be able to revert any changes to existing watch decriptors.
Additionally the caller cannot assume that the events that are
associated with a watch descriptor are within the set requested, as any
future calls to inotify_add_watch() may unintentionally modify a watch
descriptor's mask. Thus it cannot currently be guaranteed that a watch
descriptor will only generate events which have been requested. The
program must filter events which come through its watch descriptor to
within its expected range.

The usual mixed bunch. Particular good to see is the generic
touch screen driver. Will be interesting to see if this works
for other ADCs without major changes.
Core features
* Channel types
- New position relative channel type primarily for touch screen
sensors to feed the generic touchscreen driver.
New device support
* ad5586
- Add support for the AD5311R DAC.
* Generic touch screen driver as an IIO consumer.
- Note this is in input, but due to dependencies is coming through
the IIO tree.
- Specific support for this added to the at91-sama5d2 ADC.
- Various necessary DT bindings added.
Staging Drops
* ADIS16060 gyro
- A device with a very odd interface that was never cleanly supported.
It's now very difficult to get, so unlikely it'll ever be fixed up.
Cleanups and minor features and fixes
* core
- Fix y2038 timestamp issues now the core support is in place.
* 104-quad-8
- Provide some defines for magic numbers to help readability.
- Fix an off by one error in register selection
* ad7606
- Put in a missing function parameter name in a prototype.
* adis16023
- Use generic sign_extend function rather than local version.
* adis16240
- Use generic sign_extend funciton rather than local version.
* at91-sama5d2
- Drop dependency on HAS_DMA now this is handled elsewhere. Will
improve build test coverage.
- Add oversampling ratio control. Note there is a minor ABI change
here to increase the apparent depth to 14 bits so as to allow
for transparent provision of different oversampling ratios that
drop the actual bit depth to 13 or 12 bits.
* hx711
- Add a MAINTAINERS entry for this device.
* inv_mpu6050
- Replace the timestamp fifo 'special' code with generic timestamp
handling.
- Switch to using local store of timestamp divider rather than rate
as that is more helpful for accurate time measurement.
- Fix an unaligned access that didn't seem to be causing any trouble.
- Use the fifo overflow bit to track the overflow status rather than
a software counter.
- New timestamping mechanism to deal with missed sample interrupts.
* stm32-adc
- Drop HAS_DMA build dependency.
* sun4i-gpadc
- Select REGMAP_IRQ a very rarely hit build issue fix.

First set of IIO new device support, features and cleanups in the 4.19 cycle
The usual mixed bunch. Particular good to see is the generic
touch screen driver. Will be interesting to see if this works
for other ADCs without major changes.
Core features
* Channel types
- New position relative channel type primarily for touch screen
sensors to feed the generic touchscreen driver.
New device support
* ad5586
- Add support for the AD5311R DAC.
* Generic touch screen driver as an IIO consumer.
- Note this is in input, but due to dependencies is coming through
the IIO tree.
- Specific support for this added to the at91-sama5d2 ADC.
- Various necessary DT bindings added.
Staging Drops
* ADIS16060 gyro
- A device with a very odd interface that was never cleanly supported.
It's now very difficult to get, so unlikely it'll ever be fixed up.
Cleanups and minor features and fixes
* core
- Fix y2038 timestamp issues now the core support is in place.
* 104-quad-8
- Provide some defines for magic numbers to help readability.
- Fix an off by one error in register selection
* ad7606
- Put in a missing function parameter name in a prototype.
* adis16023
- Use generic sign_extend function rather than local version.
* adis16240
- Use generic sign_extend funciton rather than local version.
* at91-sama5d2
- Drop dependency on HAS_DMA now this is handled elsewhere. Will
improve build test coverage.
- Add oversampling ratio control. Note there is a minor ABI change
here to increase the apparent depth to 14 bits so as to allow
for transparent provision of different oversampling ratios that
drop the actual bit depth to 13 or 12 bits.
* hx711
- Add a MAINTAINERS entry for this device.
* inv_mpu6050
- Replace the timestamp fifo 'special' code with generic timestamp
handling.
- Switch to using local store of timestamp divider rather than rate
as that is more helpful for accurate time measurement.
- Fix an unaligned access that didn't seem to be causing any trouble.
- Use the fifo overflow bit to track the overflow status rather than
a software counter.
- New timestamping mechanism to deal with missed sample interrupts.
* stm32-adc
- Drop HAS_DMA build dependency.
* sun4i-gpadc
- Select REGMAP_IRQ a very rarely hit build issue fix.
struct itimerspec is not y2038-safe.
Introduce a new struct __kernel_itimerspec based on the kernel internal
y2038-safe struct itimerspec64.
The definition of struct __kernel_itimerspec includes two struct
__kernel_timespec.
Since struct __kernel_timespec has the same representation in native and
compat modes, so does struct __kernel_itimerspec. This helps have a common
entry point for syscalls using struct __kernel_itimerspec.
New y2038-safe syscalls will use this new type. Since most of the new
syscalls are just an update to the native syscalls with the type update,
place the new definition under CONFIG_64BIT_TIME. This helps architectures
that do not support the above config to keep using the old definition of
struct itimerspec.
Also change the get/put_itimerspec64 to use struct__kernel_itimerspec.
This will help 32 bit architectures to use the new syscalls when
architectures select CONFIG_64BIT_TIME.

This patch adds support for virtual xfrm interfaces.
Packets that are routed through such an interface
are guaranteed to be IPsec transformed or dropped.
It is a generic virtual interface that ensures IPsec
transformation, no need to know what happens behind
the interface. This means that we can tunnel IPv4 and
IPv6 through the same interface and support all xfrm
modes (tunnel, transport and beet) on it.

We already support setting an output mark at the xfrm_state,
unfortunately this does not support the input direction and
masking the marks that will be applied to the skb. This change
adds support applying a masked value in both directions.
The existing XFRMA_OUTPUT_MARK number is reused for this purpose
and as it is now bi-directional, it is renamed to XFRMA_SET_MARK.
An additional XFRMA_SET_MARK_MASK attribute is added for setting the
mask. If the attribute mask not provided, it is set to 0xffffffff,
keeping the XFRMA_OUTPUT_MARK existing 'full mask' semantics.

The AUDIT_FILTER_TYPE name is vague and misleading due to not describing
where or when the filter is applied and obsolete due to its available
filter fields having been expanded.
Userspace has already renamed it from AUDIT_FILTER_TYPE to
AUDIT_FILTER_EXCLUDE without checking if it already exists. The
userspace maintainer assures that as long as it is set to the same value
it will not be a problem since the userspace code does not treat
compiler warnings as errors. If this policy changes then checks if it
already exists can be added at the same time.

Generally target core and TCMUser seem to work fine for tape devices and
media changers. But there is at least one situation where TCMUser is not
able to support sequential access device emulation correctly.
The situation is when an initiator sends a SCSI READ CDB with a length that
is greater than the length of the tape block to read. We can distinguish
two subcases:
A) The initiator sent the READ CDB with the SILI bit being set.
In this case the sequential access device has to transfer the data from
the tape block (only the length of the tape block) and transmit a good
status. The current interface between TCMUser and the userspace does
not support reduction of the read data size by the userspace program.
The patch below fixes this subcase by allowing the userspace program to
specify a reduced data size in read direction.
B) The initiator sent the READ CDB with the SILI bit not being set.
In this case the sequential access device has to transfer the data from
the tape block as in A), but additionally has to transmit CHECK
CONDITION with the ILI bit set and NO SENSE in the sensebytes. The
information field in the sensebytes must contain the residual count.
With the below patch a user space program can specify the real read data
length and appropriate sensebytes. TCMUser then uses the se_cmd flag
SCF_TREAT_READ_AS_NORMAL, to force target core to transmit the real data
size and the sensebytes. Note: the flag SCF_TREAT_READ_AS_NORMAL is
introduced by Lee Duncan's patch "[PATCH v4] target: transport should
handle st FM/EOM/ILI reads" from Tue, 15 May 2018 18:25:24 -0700.

This is mostly updates to the usual drivers: ufs, qedf, mpt3sas, lpfc,
xfcp, hisi_sas, cxlflash, qla2xxx. In the absence of Nic, we're also
taking target updates which are mostly minor except for the tcmu
refactor. The only real core change to worry about is the removal of
high page bouncing (in sas, storvsc and iscsi). This has been well
tested and no problems have shown up so far.
