When netdev events happen, a rtnetlink_event() handler will send
messages for every event in it's white list. These messages contain
current information about a particular device, but they do not include
the iformation about which event just happened. So, it is impossible
to tell what just happend for these events.
This patch adds a new extension to RTM_NEWLINK message called IFLA_EVENT
that would have an encoding of event that triggered this
message. This would allow the the message consumer to easily determine
if it needs to perform certain actions.

Add SOF_TIMESTAMPING_OPT_TX_SWHW option to allow an outgoing packet to
be looped to the socket's error queue with a software timestamp even
when a hardware transmit timestamp is expected to be provided by the
driver.
Applications using this option will receive two separate messages from
the error queue, one with a software timestamp and the other with a
hardware timestamp. As the hardware timestamp is saved to the shared skb
info, which may happen before the first message with software timestamp
is received by the application, the hardware timestamp is copied to the
SCM_TIMESTAMPING control message only when the skb has no software
timestamp or it is an incoming packet.
While changing sw_tx_timestamp(), inline it in skb_tx_timestamp() as
there are no other users.

Add SOF_TIMESTAMPING_OPT_PKTINFO option to request a new control message
for incoming packets with hardware timestamps. It contains the index of
the real interface which received the packet and the length of the
packet at layer 2.
The index is useful with bonding, bridges and other interfaces, where
IP_PKTINFO doesn't allow applications to determine which PHC made the
timestamp. With the L2 length (and link speed) it is possible to
transpose preamble timestamps to trailer timestamps, which are used in
the NTP protocol.
While this information could be provided by two new socket options
independently from timestamping, it doesn't look like they would be very
useful. With this option any performance impact is limited to hardware
timestamping.
Use dev_get_by_napi_id() to get the device and its index. On kernels
with disabled CONFIG_NET_RX_BUSY_POLL or drivers not using NAPI, a zero
index will be returned in the control message.

Instead of having only one filter per block, introduce a list of chains
for every block. Create chain 0 by default. UAPI is extended so the user
can specify which chain he wants to change. If the new attribute is not
specified, chain 0 is used. That allows to maintain backward
compatibility. If chain does not exist and user wants to manipulate with
it, new chain is created with specified index. Also, when last filter is

using TTY subsystem instead. Currently synths access serial ports, directly
poking standard ISA ports by trying to steal them from serial driver. Some ISA
cards actually need this way of doing it, but most other synthesizers don't,
and can actually work by using the proper TTY subsystem through a new N_SPEAKUP

While working on the iproute2 generic XDP frontend, I noticed that
as of right now it's possible to have native *and* generic XDP
programs loaded both at the same time for the case when a driver
supports native XDP.
The intended model for generic XDP from b5cdae3291 ("net: Generic
XDP") is, however, that only one out of the two can be present at
once which is also indicated as such in the XDP netlink dump part.
The main rationale for generic XDP is to ease accessibility (in
case a driver does not yet have XDP support) and to generically
provide a semantical model as an example for driver developers
wanting to add XDP support. The generic XDP option for an XDP
aware driver can still be useful for comparing and testing both
implementations.
However, it is not intended to have a second XDP processing stage
or layer with exactly the same functionality of the first native
stage. Only reason could be to have a partial fallback for future
XDP features that are not supported yet in the native implementation
and we probably also shouldn't strive for such fallback and instead
encourage native feature support in the first place. Given there's
currently no such fallback issue or use case, lets not go there yet
if we don't need to.
Therefore, change semantics for loading XDP and bail out if the
user tries to load a generic XDP program when a native one is
present and vice versa. Another alternative to bailing out would
be to handle the transition from one flavor to another gracefully,
but that would require to bring the device down, exchange both
types of programs, and bring it up again in order to avoid a tiny
window where a packet could hit both hooks. Given this complicates
the logic for just a debugging feature in the native case, I went
with the simpler variant.
For the dump, remove IFLA_XDP_FLAGS that was added with b5cdae3291
and reuse IFLA_XDP_ATTACHED for indicating the mode. Dumping all
or just a subset of flags that were used for loading the XDP prog
is suboptimal in the long run since not all flags are useful for
dumping and if we start to reuse the same flag definitions for
load and dump, then we'll waste bit space. What we really just
want is to dump the mode for now.
Current IFLA_XDP_ATTACHED semantics are: nothing was installed (0),
a program is running at the native driver layer (1). Thus, add a
mode that says that a program is running at generic XDP layer (2).
Applications will handle this fine in that older binaries will
just indicate that something is attached at XDP layer, effectively
this is similar to IFLA_XDP_FLAGS attr that we would have had
modulo the redundancy.

The verifier, in this mode, will also use a fixed value of "2" in

Pull TEE driver infrastructure and OP-TEE drivers from Arnd Bergmann:
"This introduces a generic TEE framework in the kernel, to handle
trusted environemtns (security coprocessor or software implementations
such as OP-TEE/TrustZone). I'm sending it separately from the other
arm-soc driver changes to give it a little more visibility, once the
subsystem is merged, we will likely keep this in the arm₋soc drivers
branch or have the maintainers submit pull requests directly,
depending on the patch volume.
I have reviewed earlier versions in the past, and have reviewed the
latest version in person during Linaro Connect BUD17.
Here is my overall assessment of the subsystem:
- There is clearly demand for this, both for the generic
infrastructure and the specific OP-TEE implementation.
- The code has gone through a large number of reviews, and the review
comments have all been addressed, but the reviews were not coming
up with serious issues any more and nobody volunteered to vouch for
the quality.
- The user space ioctl interface is sufficient to work with the
OP-TEE driver, and it should in principle work with other TEE
implementations that follow the GlobalPlatform[1] standards, but it
might need to be extended in minor ways depending on specific
requirements of future TEE implementations
- The main downside of the API to me is how the user space is tied to
the TEE implementation in hardware or firmware, but uses a generic
way to communicate with it. This seems to be an inherent problem
with what it is trying to do, and I could not come up with any
better solution than what is implemented here.

Pull more rdma updates from Doug Ledford:
"As mentioned in my first pull request, this is the subsequent pull
requests I had. This is all I have, and in fact this cleans out the
RDMA subsystem's entire patchworks queue of kernel changes that are
ready to go (well, it did for the weekend anyway, a few new patches
are in, but they'll be coming during the -rc cycle).
The first tag contains a single patch that would have conflicted if
taken from my tree or DaveM's tree as it needed our trees merged to
come cleanly.
The second tag contains the patch series from Intel plus three other
stragllers that came in late last week. I took them because it allowed
me to legitimately claim that the RDMA patchworks queue was, for a
short time, 100% cleared of all waiting kernel patches, woohoo! :-).
I have it under my for-next tag, so it did get 0day and linux- next
over the end of last week, and linux-next did show one minor conflict.

Pull libnvdimm updates from Dan Williams:
"The bulk of this has been in multiple -next releases. There were a few
late breaking fixes and small features that got added in the last
couple days, but the whole set has received a build success
notification from the kbuild robot.
Change summary:
- Region media error reporting: A libnvdimm region device is the
parent to one or more namespaces. To date, media errors have been
reported via the "badblocks" attribute attached to pmem block
devices for namespaces in "raw" or "memory" mode. Given that
namespaces can be in "device-dax" or "btt-sector" mode this new
interface reports media errors generically, i.e. independent of
namespace modes or state.
This subsequently allows userspace tooling to craft "ACPI 6.1
Section 9.20.7.6 Function Index 4 - Clear Uncorrectable Error"
requests and submit them via the ioctl path for NVDIMM root bus
devices.
- Introduce 'struct dax_device' and 'struct dax_operations': Prompted
by a request from Linus and feedback from Christoph this allows for
dax capable drivers to publish their own custom dax operations.
This fixes the broken assumption that all dax operations are
related to a persistent memory device, and makes it easier for
other architectures and platforms to add customized persistent
memory support.
- 'libnvdimm' core updates: A new "deep_flush" sysfs attribute is
available for storage appliance applications to manually trigger
memory controllers to drain write-pending buffers that would
otherwise be flushed automatically by the platform ADR
(asynchronous-DRAM-refresh) mechanism at a power loss event.
Support for "locked" DIMMs is included to prevent namespaces from
surfacing when the namespace label data area is locked. Finally,
fixes for various reported deadlocks and crashes, also tagged for
-stable.
- ACPI / nfit driver updates: General updates of the nfit driver to
add DSM command overrides, ACPI 6.1 health state flags support, DSM
payload debug available by default, and various fixes.

"Highlights include:
- Larger virtual address space on 64-bit server CPUs. By default we
use a 128TB virtual address space, but a process can request access
to the full 512TB by passing a hint to mmap().
- Support for the new Power9 "XIVE" interrupt controller.
- TLB flushing optimisations for the radix MMU on Power9.
- Support for CAPI cards on Power9, using the "Coherent Accelerator
Interface Architecture 2.0".
- The ability to configure the mmap randomisation limits at build and
runtime.
- Several small fixes and cleanups to the kprobes code, as well as
support for KPROBES_ON_FTRACE.
- Major improvements to handling of system reset interrupts,
correctly treating them as NMIs, giving them a dedicated stack and
using a new hypervisor call to trigger them, all of which should
aid debugging and robustness.
- Many fixes and other minor enhancements.

Lots of good stuff here, after many many many attempts, the kernel

wasn't an easy path for them at all.
There's also a staging driver that uses this new api, which is why
it's coming in through this tree.
Along with that, there's the usual huge number of changes for gadget
drivers, xhci, and other stuff. Johan also finally refactored pretty
much every driver that was looking at USB endpoints to do it in a
common way, which will help prevent any "badly-formed" devices from
causing problems in drivers. That too wasn't a simple task.

Per the latest version of the "NVDIMM DSM Interface Example" [1], the
label data retrieval routine can report a "locked" status. In this case
all regions associated with that DIMM are disabled until the label area
is unlocked. Provide generic libnvdimm enabling for NVDIMMs with label
data area locking capabilities.

1) The wireless rate info fix from Johannes Berg.
2) When a RAW socket is in hdrincl mode, we need to make sure that the
user provided at least a minimally sized ipv4/ipv6 header. Fix from
Alexander Potapenko.
3) We must emit IFLA_PHYS_PORT_NAME netlink attributes using
nla_put_string() so that it is NULL terminated.
4) Fix a bug in TCP fastopen handling, wherein child sockets
erroneously inherit the fastopen_req from the parent, and later can
end up derefencing freed memory or doing a double free. From Eric
Dumazet.
5) Don't clear out netdev stats at close time in tg3 driver, from
YueHaibing.
6) Fix refcount leak in xt_CT, from Gao Feng.
7) In nft_set_bitmap() don't leak dummy elements, from Liping Zhang.
8) Fix deadlock due to taking the expectation lock twice, also from
Liping Zhang.
9) Make xt_socket work again with ipv6, from Peter Tirsek.
10) Don't allow IPV6 to be used with IPVS if ipv6.disable=1, from Paolo
Abeni.
11) Make the BPF loader more flexible wrt. changes to the bpf MAP entry
layout. From Jesper Dangaard Brouer.
12) Fix ethtool reported device name in aquantia driver, from Pavel
Belous.
13) Fix build failures due to the compile time size test not working in
netfilter conntrack. From Geert Uytterhoeven.

Pull rdma updates from Doug Ledford:
"More exchaustive description of primary updates in this release:
- Lots of driver fixes and misc fixes across the board.
- I had to base on a net-next tree because the IPoIB Accelorator
patches needed it.
Unfortunately, it was known to Mellanox that there would need to be
an IPoIB accelorator patch to the net tree (which left some
functions turned off by an #ifdef construct to avoid warnings about
defined but unused functions), then one to the RDMA tree, then a
fixup that went back and re-enabled the functions in the net tree
and enabled their use in the rdma tree
Also, a sparse fix was sent to the net tree after I did my pull,
and the fixup patch conflicts quite directly with that sparse fix,
so I'm going to submit the fixup patch towards the end of the merge
window by itself and based upon your master branch at the time.
- Two separate rounds of hfi1 fixes, one that got dropped from last
release because it came in just a day or two before the end of the
merge window and then the one from this release cycle.
Of note is that I now have a third series that just landed from
Intel yesterday. It is not included in this pull request, but I may
submit it by the end of the week. I'll talk to Intel about
improving the timing of thier submissions for my workflow.
- Changes to our idr usage in the RDMA subsystem that will tie into
our cgroup management and also into the upcoming changes for the
RDMA kernel<->userspace API.
- Addition of support for a netdev to be tied to an RDMA device at
the core level
- Addition of the VNIC driver from Intel.
While IPoIB provides IP over InfiniBand (and *only* IP, no lower
layer protocol headers are allowed or supported), the VNIC driver
presents a virtual Ethernet device with support for things like
varying Ethertypes, VLANs, priorities and other features of
Ethernet.
The virtual devices are centrally managed by the OPA fabric
manager, making this (for the time being) a strictly OPA specific
feature.
- Improvements to the On-Demand Paging support in the RDMA subsystem.
- Addition of three significant OPA changes.
While we added OPA support some time ago (via the hfi1 driver), the
RDMA subsystem has so far glossed over the areas where OPA and
InfiniBand differ.
With this release we are starting to add support for the OPA
extensions into the RDMA core in the following area: Extended port
information for OPA is now supported, extended Address Handle
attributes for OPA are now supported, and extended SA Queries to
get OPA specific subnet information is now supported.
Concise summary from the tag:
- idr usage and locking changes
- build fix for hns
- ipoib debug path record file fix
- hfi1 updates
- core RDMA netdev addition
- Intel VNIC driver addition
- Enhanced accelerators for IPoIB addition
- Debug cleanups in cxgb3/4

- Misc rxe fixes from Mellanox
- Misc ipoib fixes from Mellanox
- Lots of mlx4/mlx5 changes from Mellanox
- Misc fixes across the RDMA subsystem
- ODP paging fixes and improvements
- qedr updates
- hfi1 updates
