Pull audit updates from Paul Moore:
"After the small number of patches for v4.9, we've got a much bigger
pile for v4.10.
The bulk of these patches involve a rework of the audit backlog queue
to enable us to move the netlink multicasting out of the task/thread
that generates the audit record and into the kernel thread that emits
the record (just like we do for the audit unicast to auditd).
While we were playing with the backlog queue(s) we fixed a number of
other little problems with the code, and from all the testing so far
things look to be in much better shape now. Doing this also allowed us
to re-enable disabling IRQs for some netns operations ("netns: avoid
disabling irq for netns id").
The remaining patches fix some small problems that are well documented
in the commit descriptions, as well as adding session ID filtering
support"

This patch series adds a driver for a paravirtual RDMA device. The
device is developed for VMware's Virtual Machines and allows existing RDMA
applications to continue to use existing Verbs API when deployed in VMs
on ESXi. We recently did a presentation in the OFA Workshop [1] regarding
this device.
Description and RDMA Support
============================
The virtual device is exposed as a dual function PCIe device. One part
is a virtual network device (VMXNet3) which provides networking properties
like MAC, IP addresses to the RDMA part of the device. The networking
properties are used to register GIDs required by RDMA applications to
communicate.
These patches add support and the all required infrastructure for
letting applications use such a device. We support the mandatory Verbs API as
well as the base memory management extensions (Local Inv, Send with Inv and
Fast Register Work Requests). We currently support both Reliable Connected
and Unreliable Datagram QPs but do not support Shared Receive Queues
(SRQs).
Also, we support the following types of Work Requests:
o Send/Receive (with or without Immediate Data)
o RDMA Write (with or without Immediate Data)
o RDMA Read
o Local Invalidate
o Send with Invalidate
o Fast Register Work Requests
This version only adds support for version 1 of RoCE. We will add RoCEv2
support in a future patch. We do support registration of both MAC-based
and IP-based GIDs. I have also created a git tree for our user-level driver
[2].
Testing
=======
We have tested this internally for various types of Guest OS - Red Hat,
Centos, Ubuntu 12.04/14.04/16.04, Oracle Enterprise Linux, SLES 12
using backported versions of this driver. The tests included several
runs of the performance tests (included with OFED), Intel MPI PingPong
benchmark on OpenMPI, krping for FRWRs. Mellanox has been kind enough
to test the backported version of the driver internally on their hardware
using a VMware provided ESX build. I have also applied and tested this
with Doug's k.o/for-4.9 branch (commit 5603910b). Note, that this patch
series should be applied all together. I split out the commits so that
it may be easier to review.

No dramatic changes are found in this development cycle, but as usual,
many commits are applied in a wide range of drivers.
Most of big changes are in ASoC, where a few bits of framework work
and quite a lot of cleanups and improvements to existing code have
been done. The rest are usual stuff, a few HD-audio and USB-audio
quirks and fixes, as well as the drop of kthread usages in the whole
subsystem.
Below are some highlights:
ASoC:
- Support for stereo DAPM controls
- Some initial work on the of-graph sound card
- regmap conversions of the remaining AC'97 drivers
- A new version of the topology ABI; this should be backward compatible
- Updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
Intel skylake, atom-sst
- New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
Realtek RT5665
USB-audio:
- Yet another race fix at disconnection
- Tolerated packet size calculation for some Android devices
- Quirks for Axe-Fx II, QuickCam, TEAC 501/503
HD-audio:
- Improvement of Dell pin fixup mapping
- Quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic
Misc:
- Replace all kthread usages with simple works

Pull MD updates from Shaohua Li:
- a raid5 writeback cache feature.
The goal is to aggregate writes to make full stripe write and reduce
read-modify-write. It's helpful for workload which does sequential
write and follows fsync for example. This feature is experimental and
off by default right now.
- FAILFAST support.
This fails IOs to broken raid disks quickly, so can improve latency.
It's mainly for DASD storage, but some patches help normal raid array
too.
- support bad block for raid array with external metadata
- AVX2 instruction support for raid6 parity calculation

Here's the "big" staging/iio pull request for 4.10-rc1.
Not as big as 4.9 was, but still just over a thousand changes. We
almost broke even of lines added vs. removed, as the slicoss driver was
removed (got a "clean" driver for the same hardware through the netdev
tree), and some iio drivers were also dropped, but I think we ended up
adding a few thousand lines to the source tree in the end. Other than
that it's a lot of minor fixes all over the place, nothing major stands
out at all.
All of these have been in linux-next for a while. There will be a merge

Pull block layer updates from Jens Axboe:
"This is the main block pull request this series. Contrary to previous
release, I've kept the core and driver changes in the same branch. We
always ended up having dependencies between the two for obvious
reasons, so makes more sense to keep them together. That said, I'll
probably try and keep more topical branches going forward, especially
for cycles that end up being as busy as this one.
The major parts of this pull request is:
- Improved support for O_DIRECT on block devices, with a small
private implementation instead of using the pig that is
fs/direct-io.c. From Christoph.
- Request completion tracking in a scalable fashion. This is utilized
by two components in this pull, the new hybrid polling and the
writeback queue throttling code.
- Improved support for polling with O_DIRECT, adding a hybrid mode
that combines pure polling with an initial sleep. From me.
- Support for automatic throttling of writeback queues on the block
side. This uses feedback from the device completion latencies to
scale the queue on the block side up or down. From me.
- Support from SMR drives in the block layer and for SD. From Hannes
and Shaun.
- Multi-connection support for nbd. From Josef.
- Cleanup of request and bio flags, so we have a clear split between
which are bio (or rq) private, and which ones are shared. From
Christoph.
- A set of patches from Bart, that improve how we handle queue
stopping and starting in blk-mq.
- Support for WRITE_ZEROES from Chaitanya.
- Lightnvm updates from Javier/Matias.
- Supoort for FC for the nvme-over-fabrics code. From James Smart.
- A bunch of fixes from a whole slew of people, too many to name
here"

- VFIO updates for v4.10 primarily include a new Mediated Device
interface, which essentially allows software defined devices to be
exposed to users through VFIO. The host vendor driver providing
this virtual device polices, or mediates user access to the device.
These devices often incorporate portions of real devices, for
instance the primary initial users of this interface expose vGPUs
which allow the user to map mediated devices, or mdevs, to a
portion of a physical GPU. QEMU composes these mdevs into PCI
representations using the existing VFIO user API. This enables
both Intel KVM-GT support, which is also expected to arrive into
Linux mainline during the v4.10 merge window, as well as NVIDIA
vGPU, and also Channel I/O devices (aka CCW devices) for s390
virtualization support. (Kirti Wankhede, Neo Jia)
- Drop unnecessary uses of pcibios_err_to_errno() (Cao Jin)
- Fixes to VFIO capability chain handling (Eric Auger)

Merge tag 'vfio-v4.10-rc1' of git://github.com/awilliam/linux-vfio
Pull VFIO updates from Alex Williamson:
- VFIO updates for v4.10 primarily include a new Mediated Device
interface, which essentially allows software defined devices to be
exposed to users through VFIO. The host vendor driver providing this
virtual device polices, or mediates user access to the device.
These devices often incorporate portions of real devices, for
instance the primary initial users of this interface expose vGPUs
which allow the user to map mediated devices, or mdevs, to a portion
of a physical GPU. QEMU composes these mdevs into PCI representations
using the existing VFIO user API. This enables both Intel KVM-GT
support, which is also expected to arrive into Linux mainline during
the v4.10 merge window, as well as NVIDIA vGPU, and also Channel I/O
devices (aka CCW devices) for s390 virtualization support. (Kirti
Wankhede, Neo Jia)

NL80211_ATTR_MAC was used to set both the specific BSSID to be scanned
and the random MAC address to be used when privacy is enabled. When both
the features are enabled, both the BSSID and the local MAC address were
getting same value causing Probe Request frames to go with unintended
DA. Hence, this has been fixed by using a different NL80211_ATTR_BSSID
attribute to set the specific BSSID (which was the more recent addition
in cfg80211) for a scan.
Backwards compatibility with old userspace software is maintained to
some extent by allowing NL80211_ATTR_MAC to be used to set the specific
BSSID when scanning without enabling random MAC address use.
Scanning with random source MAC address was introduced by commit
ad2b26abc1 ("cfg80211: allow drivers to support random MAC addresses
for scan") and the issue was introduced with the addition of the second
user for the same attribute in commit 818965d391 ("cfg80211: Allow a
scan request for a specific BSSID").

This patch allows XDP prog to extend/remove the packet
data at the head (like adding or removing header). It is
done by adding a new XDP helper bpf_xdp_adjust_head().
It also renames bpf_helper_changes_skb_data() to
bpf_helper_changes_pkt_data() to better reflect
that XDP prog does not work on skb.
This patch adds one "xdp_adjust_head" bit to bpf_prog for the
XDP-capable driver to check if the XDP prog requires
bpf_xdp_adjust_head() support. The driver can then decide
to error out during XDP_SETUP_PROG.

====================
Netfilter/IPVS updates for net-next
The following patchset contains a large Netfilter update for net-next,
to summarise:
1) Add support for stateful objects. This series provides a nf_tables
native alternative to the extended accounting infrastructure for
nf_tables. Two initial stateful objects are supported: counters and
quotas. Objects are identified by a user-defined name, you can fetch
and reset them anytime. You can also use a maps to allow fast lookups
using any arbitrary key combination. More info at:
http://marc.info/?l=netfilter-devel&m=148029128323837&w=2
2) On-demand registration of nf_conntrack and defrag hooks per netns.
Register nf_conntrack hooks if we have a stateful ruleset, ie.
state-based filtering or NAT. The new nf_conntrack_default_on sysctl
enables this from newly created netnamespaces. Default behaviour is not
modified. Patches from Florian Westphal.
3) Allocate 4k chunks and then use these for x_tables counter allocation
requests, this improves ruleset load time and also datapath ruleset
evaluation, patches from Florian Westphal.
4) Add support for ebpf to the existing x_tables bpf extension.
From Willem de Bruijn.
5) Update layer 4 checksum if any of the pseudoheader fields is updated.
This provides a limited form of 1:1 stateless NAT that make sense in
specific scenario, eg. load balancing.
6) Add support to flush sets in nf_tables. This series comes with a new
set->ops->deactivate_one() indirection given that we have to walk
over the list of set elements, then deactivate them one by one.
The existing set->ops->deactivate() performs an element lookup that
we don't need.
7) Two patches to avoid cloning packets, thus speed up packet forwarding
via nft_fwd from ingress. From Florian Westphal.
8) Two IPVS patches via Simon Horman: Decrement ttl in all modes to
prevent infinite loops, patch from Dwip Banerjee. And one minor
refactoring from Gao feng.
9) Revisit recent log support for nf_tables netdev families: One patch
to ensure that we correctly handle non-ethernet packets. Another
patch to add missing logger definition for netdev. Patches from
Liping Zhang.
10) Three patches for nft_fib, one to address insufficient register
initialization and another to solve incorrect (although harmless)
byteswap operation. Moreover update xt_rpfilter and nft_fib to match
lbcast packets with zeronet as source, eg. DHCP Discover packets
(0.0.0.0 -> 255.255.255.255). Also from Liping Zhang.
11) Built-in DCCP, SCTP and UDPlite conntrack and NAT support, from
Davide Caratti. While DCCP is rather hopeless lately, and UDPlite has
been broken in many-cast mode for some little time, let's give them a
chance by placing them at the same level as other existing protocols.
Thus, users don't explicitly have to modprobe support for this and
NAT rules work for them. Some people point to the lack of support in
SOHO Linux-based routers that make deployment of new protocols harder.
I guess other middleboxes outthere on the Internet are also to blame.
Anyway, let's see if this has any impact in the midrun.
12) Skip software SCTP software checksum calculation if the NIC comes
with SCTP checksum offload support. From Davide Caratti.
13) Initial core factoring to prepare conversion to hook array. Three
patches from Aaron Conole.
14) Gao Feng made a wrong conversion to switch in the xt_multiport
extension in a patch coming in the previous batch. Fix it in this
batch.
15) Get vmalloc call in sync with kmalloc flags to avoid a warning
and likely OOM killer intervention from x_tables. From Marcelo
Ricardo Leitner.
16) Update Arturo Borrero's email address in all source code headers.

This patch adds a new flag that signals the kernel to update layer 4
checksum if the packet field belongs to the layer 4 pseudoheader. This
implicitly provides stateless NAT 1:1 that is useful under very specific
usecases.
Since rules mangling layer 3 fields that are part of the pseudoheader
may potentially convey any layer 4 packet, we have to deal with the
layer 4 checksum adjustment using protocol specific code.
This patch adds support for TCP, UDP and ICMPv6, since they include the
pseudoheader in the layer 4 checksum calculation. ICMP doesn't, so we
can skip it.

When loading a BPF program via bpf(2), calculate the digest over
the program's instruction stream and store it in struct bpf_prog's
digest member. This is done at a point in time before any instructions
are rewritten by the verifier. Any unstable map file descriptor
number part of the imm field will be zeroed for the hash.
fdinfo example output for progs:
# cat /proc/1590/fdinfo/5
pos: 0
flags: 02000002
mnt_id: 11
prog_type: 1
prog_jited: 1
prog_digest: b27e8b06da22707513aa97363dfb11c7c3675d28
memlock: 4096
When programs are pinned and retrieved by an ELF loader, the loader
can check the program's digest through fdinfo and compare it against
one that was generated over the ELF file's program section to see
if the program needs to be reloaded. Furthermore, this can also be
exposed through other means such as netlink in case of a tc cls/act
dump (or xdp in future), but also through tracepoints or other
facilities to identify the program. Other than that, the digest can
also serve as a base name for the work in progress kallsyms support
of programs. The digest doesn't depend/select the crypto layer, since
we need to keep dependencies to a minimum. iproute2 will get support
for this facility.

Implemented RFC7527 Enhanced DAD.
IPv6 duplicate address detection can fail if there is some temporary
loopback of Ethernet frames. RFC7527 solves this by including a random
nonce in the NS messages used for DAD, and if an NS is received with the
same nonce it is assumed to be a looped back DAD probe and is ignored.
RFC7527 is enabled by default. Can be disabled by setting both of

2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix

3) In 'net' we had several probe error path bug fixes to the

and reorganized in 'net-next'.
4) The cls_flower classifier obtained a helper function in
'net-next' called __fl_delete() and this overlapped with
Daniel Borkamann's bug fix to use RCU for object destruction
in 'net'. It also overlapped with Jiri's change to guard
the rhashtable_remove_fast() call with a check against
tc_skip_sw().
5) In mlx4, a revert bug fix in 'net' overlapped with some
unrelated changes in 'net-next'.
6) In geneve, a stale header pointer after pskb_expand_head()
bug fix in 'net' overlapped with a large reorganization of
the same code in 'net-next'. Since the 'net-next' code no
longer had the bug in question, there was nothing to do

Add new cgroup based program type, BPF_PROG_TYPE_CGROUP_SOCK. Similar to
BPF_PROG_TYPE_CGROUP_SKB programs can be attached to a cgroup and run
any time a process in the cgroup opens an AF_INET or AF_INET6 socket.
Currently only sk_bound_dev_if is exported to userspace for modification
by a bpf program.
This allows a cgroup to be configured such that AF_INET{6} sockets opened
by processes are automatically bound to a specific device. In turn, this
enables the running of programs that do not support SO_BINDTODEVICE in a

Registers new BPF program types which correspond to the LWT hooks:
- BPF_PROG_TYPE_LWT_IN => dst_input()
- BPF_PROG_TYPE_LWT_OUT => dst_output()
- BPF_PROG_TYPE_LWT_XMIT => lwtunnel_xmit()
The separate program types are required to differentiate between the
capabilities each LWT hook allows:
* Programs attached to dst_input() or dst_output() are restricted and
may only read the data of an skb. This prevent modification and
possible invalidation of already validated packet headers on receive
and the construction of illegal headers while the IP headers are
still being assembled.
* Programs attached to lwtunnel_xmit() are allowed to modify packet
content as well as prepending an L2 header via a newly introduced
helper bpf_skb_change_head(). This is safe as lwtunnel_xmit() is
invoked after the IP header has been assembled completely.
All BPF programs receive an skb with L3 headers attached and may return
one of the following error codes:
BPF_OK - Continue routing as per nexthop
BPF_DROP - Drop skb and return EPERM
BPF_REDIRECT - Redirect skb to device as per redirect() helper.
(Only valid in lwtunnel_xmit() context)
The return codes are binary compatible with their TC_ACT_
relatives to ease compatibility.

is working. I've been working through deqp, and I've got a couple more
things to fix (but we've gone from 70% to 80+% pass in last day, and
current deqp run that is going should pick up another 5-10%). I expect
to push the mesa patches today or tomorrow.
There are a couple more a5xx related patches to take the gpu out of
secure mode (for the devices that come up in secure mode, like the hw
I have), but those depend on an scm patch that would come in through
another tree. If that can land in the next day or two, there might
be a second late pull request for drm/msm.
In addition to the new-shiny, there have also been a lot of overlay/
plane related fixes for issues found using drm-hwc2 (in the process of
testing/debugging the atomic/kms fence patches), resulting in rework
to assign hwpipes to kms planes dynamically (as part of global atomic
state) and also handling SMP (fifo) block allocation atomically as
part of the ->atomic_check() step. All those patches should also help
out atomic weston (when those patches eventually land).

Add an IFLA_XDP_FLAGS attribute that can be passed for setting up
XDP along with IFLA_XDP_FD, which eventually allows user space to
implement typical add/replace/delete logic for programs. Right now,
calling into dev_change_xdp_fd() will always replace previous programs.
When passed XDP_FLAGS_UPDATE_IF_NOEXIST, we can handle this more
graceful when requested by returning -EBUSY in case we try to
attach a new program, but we find that another one is already
attached. This will be used by upcoming front-end for iproute2 as
well.

This patch exports the sender chronograph stats via the socket
SO_TIMESTAMPING channel. Currently we can instrument how long a
particular application unit of data was queued in TCP by tracking
SOF_TIMESTAMPING_TX_SOFTWARE and SOF_TIMESTAMPING_TX_SCHED. Having
these sender chronograph stats exported simultaneously along with
these timestamps allow further breaking down the various sender
limitation. For example, a video server can tell if a particular
chunk of video on a connection takes a long time to deliver because
TCP was experiencing small receive window. It is not possible to
tell before this patch without packet traces.
To prepare these stats, the user needs to set
SOF_TIMESTAMPING_OPT_STATS and SOF_TIMESTAMPING_OPT_TSONLY flags
while requesting other SOF_TIMESTAMPING TX timestamps. When the
timestamps are available in the error queue, the stats are returned
in a separate control message of type SCM_TIMESTAMPING_OPT_STATS,
in a list of TLVs (struct nlattr) of types: TCP_NLA_BUSY_TIME,
TCP_NLA_RWND_LIMITED, TCP_NLA_SNDBUF_LIMITED. Unit is microsecond.

This patch exports all the sender chronograph measurements collected
in the previous patches to TCP_INFO interface. Note that busy time
exported includes all the other sending limits (rwnd-limited,
sndbuf-limited). Internally the time unit is jiffy but externally
the measurements are in microseconds for future extensions.

It is used for limitation of buffer size during IOCTL such as FFU.
However, eMMC FW size is bigger than (512L*256).
(For instance, currently, Samsung eMMC FW size is over 300KB.)
So, it needs to increase to execute FFU.

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.
