  "It's mostly small bugfixes and cleanups, mostly around x86 nested
   virtualization.  One important change, not related to nested
   virtualization, is that the ability for the guest kernel to trap
   CPUID instructions (in Linux that's the ARCH_SET_CPUID arch_prctl) is
   now masked by default.  This is because the feature is detected
   through an MSR; a very bad idea that Intel seems to like more and
   more.  Some applications choke if the other fields of that MSR are
   not initialized as on real hardware, hence we have to disable the
   whole MSR by default, as was the case before Linux 4.12."

e013477bc2 usb: usbtmc: Add ioctl USBTMC_IOCTL_API_VERSION
Add ioctl USBTMC_IOCTL_API_VERSION to get current API version
of usbtmc driver.

This is to allow an instrument library to determine whether
the driver API is compatible with the implementation.

The API may change in future versions. Therefore the macro
USBTMC_API_VERSION should be incremented when changing tmc.h
with new flags, ioctls or when changing a significant behavior
of the driver.

8409e96f01 usb: usbtmc: add ioctl USBTMC_IOCTL_MSG_IN_ATTR
add ioctl USBTMC_IOCTL_MSG_IN_ATTR that returns the specific
bmTransferAttributes field of the last DEV_DEP_MSG_IN Bulk-IN
header. This header is received by the read() function. The
meaning of the (u8) bitmap bmTransferAttributes is:

Bit 0 = EOM flag is set when the last transfer of a USBTMC
message is received.

Bit 1 = is set when the last byte is a termchar (e.g. '\n').
Note that this bit is always zero when the device does not support
the termchar feature or when termchar detection is not enabled
(see ioctl USBTMC_IOCTL_CONFIG_TERMCHAR).

bb99794a47 usb: usbtmc: Add ioctl for vendor specific read
The USBTMC_IOCTL_READ call provides for generic synchronous and
asynchronous reads on bulk IN to implement vendor specific library
routines.

Depending on transfer_size the function submits one or more urbs (up
to 16) each with a size of up to 4kB.

The flag USBTMC_FLAG_IGNORE_TRAILER can be used when the transmission
size is already known. Then the function does not truncate the
transfer_size to a multiple of 4 kB, but does reserve extra space
to receive the final short or zero length packet. Note that the
instrument is allowed to send up to wMaxPacketSize - 1 bytes at the
end of a message to avoid sending a zero length packet.

With flag USBTMC_FLAG_ASYNC the ioctl is non blocking. When no
received data is available, the read function submits as many urbs as
needed to receive transfer_size bytes. However the number of flying
urbs (=4kB) is limited to 16 even with subsequent calls of this ioctl.

Returns -EAGAIN when non blocking and no data is received.
Signals EPOLLIN | EPOLLRDNORM when asynchronous urbs are ready to
be read.

In non blocking mode the usbtmc_message.message pointer may be NULL
and the ioctl just submits urbs to initiate receiving data. However if
data is already available due to a previous non blocking call the ioctl
will return -EINVAL when the message pointer is NULL.

This ioctl does not support compatibility for 32 bit
applications running on 64 bit systems. However all other
convenient ioctls of the USBTMC driver can still be used in 32
bit applications as well. Note that 32 bit applications running
on 32 bit target systems are not affected by this limitation.

4ddc645f40 usb: usbtmc: Add ioctl for vendor specific write
The new ioctl USBTMC_IOCTL_WRITE sends a generic message to bulk OUT.
This ioctl is used for vendor specific or asynchronous I/O as well.

The message is split into chunks of 4k (page size).
Message size is aligned to 32 bit boundaries.

With flag USBTMC_FLAG_ASYNC the ioctl is non blocking.
With flag USBTMC_FLAG_APPEND additional urbs are queued and
out_status/out_transfer_size is not reset. EPOLLOUT | EPOLLWRNORM
is signaled when all submitted urbs are completed.

Flush flying urbs when file handle is closed or device is
suspended or reset.

6fbbde9a19 KVM: x86: Control guest reads of MSR_PLATFORM_INFO
Add KVM_CAP_MSR_PLATFORM_INFO so that userspace can disable guest access
to reads of MSR_PLATFORM_INFO.

Disabling access to reads of this MSR gives userspace the control to "expose"
this platform-dependent information to guests in a clear way. As it exists
today, guests that read this MSR would get unpopulated information if userspace
hadn't already set it (and prior to this patch series, only the CPUID faulting
information could have been populated). This existing interface could be
confusing if guests don't handle the potential for incorrect/incomplete
information gracefully (e.g. zero reported for base frequency).

9a59739bd0 IB/rxe: Revise the ib_wr_opcode enum
This enum has become part of the uABI, as both RXE and the
ib_uverbs_post_send() command expect userspace to supply values from this
enum. So it should be properly placed in include/uapi/rdma.

In userspace this enum is called 'enum ibv_wr_opcode' as part of
libibverbs.h. That enum defines different values for IB_WR_LOCAL_INV,
IB_WR_SEND_WITH_INV, and IB_WR_LSO. These were introduced (incorrectly, it
turns out) into libiberbs in 2015.

The kernel has changed its mind on the numbering for several of the IB_WC
values over the years, but has remained stable on IB_WR_LOCAL_INV and
below.

Based on this we can conclude that there is no real user space user of the
values beyond IB_WR_ATOMIC_FETCH_AND_ADD, as they have never worked via
rdma-core. This is confirmed by inspection, only rxe uses the kernel enum
and implements the latter operations. rxe has clearly never worked with
these attributes from userspace. Other drivers that support these opcodes
implement the functionality without calling out to the kernel.

To make IB_WR_SEND_WITH_INV and related work for RXE in userspace we
choose to renumber the IB_WR enum in the kernel to match the uABI that
userspace has bee using since before Soft RoCE was merged. This is an
overall simpler configuration for the whole software stack, and obviously
can't break anything existing.

15033f0457 ipv6: Add sockopt IPV6_MULTICAST_ALL analogue to IP_MULTICAST_ALL
The socket option will be enabled by default to ensure current behaviour
is not changed. This is the same for the IPv4 version.

A socket bound to in6addr_any and a specific port will receive all traffic
on that port. Analogue to IP_MULTICAST_ALL, disable this behaviour, if
one or more multicast groups were joined (using said socket) and only
pass on multicast traffic from groups, which were explicitly joined via
this socket.

Without this option disabled a socket (system even) joined to multiple
multicast groups is very hard to get right. Filtering by destination
address has to take place in user space to avoid receiving multicast
traffic from other multicast groups, which might have traffic on the same
port.

The extension of the IP_MULTICAST_ALL socketoption to just apply to ipv6,
too, is not done to avoid changing the behaviour of current applications.

435f2e7cc0 net: bridge: add support for sticky fdb entries
Add support for entries which are "sticky", i.e. will not change their port
if they show up from a different one. A new ndm flag is introduced for that
purpose - NTF_STICKY. We allow to set it only to non-local entries.

a7ee18bdee RDMA/mlx5: Allow creating a matcher for a NIC TX flow table
Currently a matcher can only be created and attached to a NIC RX flow
table. Extend it to allow it on NIC TX flow tables as well.

In order to achieve that, we:

1) Expose a new attribute: MLX5_IB_ATTR_FLOW_MATCHER_FLOW_FLAGS.
   enum ib_flow_flags is used as valid flags. Only
   IB_FLOW_ATTR_FLAGS_EGRESS is supported.

2) Remove the requirement to have a DEVX or QP destination when creating a
   flow. A flow added to NIC TX flow table will forward the packet outside
   of the vport (Wire or E-Switch in the SR-iOV case).

Methods sometimes need to get a flexible set of IDRs and not a strict set
as can be achieved today by the conventional IDR attribute. Add a new
IDRS_ARRAY attribute to the generic uverbs ioctl layer.

IDRS_ARRAY points to array of idrs of the same object type and same access
rights, only write and read are supported.

fa788d986a packet: add sockopt to ignore outgoing packets
Currently, the only way to ignore outgoing packets on a packet socket is
via the BPF filter.  With MSG_ZEROCOPY, packets that are looped into
AF_PACKET are copied in dev_queue_xmit_nit(), and this copy happens even
if the filter run from packet_rcv() would reject them.  So the presence
of a packet socket on the interface takes away the benefits of
MSG_ZEROCOPY, even if the packet socket is not interested in outgoing
packets.  (Even when MSG_ZEROCOPY is not used, the skb is unnecessarily
cloned, but the cost for that is much lower.)

Add a socket option to allow AF_PACKET sockets to ignore outgoing
packets to solve this.  Note that the *BSDs already have something
similar: BIOCSSEESENT/BIOCSDIRECTION and BIOCSDIRFILT.

The first intended user is lldpd.

2b815b04df nl80211: Add CAN_REPLACE_PTK0 API
Drivers able to correctly replace a in-use key should set
@NL80211_EXT_FEATURE_CAN_REPLACE_PTK0 to allow the user space (e.g.
hostapd or wpa_supplicant) to rekey PTK keys.

The user space must detect a PTK rekey attempt and only go ahead with it
when the driver has set this flag. If the driver is not supporting the
feature the user space either must not replace the PTK key or perform a
full re-association instead.

Ignoring this flag and continuing to rekey the connection can still work
but has to be considered insecure and broken. Depending on the driver it
can leak clear text packets or freeze the connection and is only
supported to allow the user space to be updated.
