The member subscribe in sctp_sock is used to indicate to which of
the events it is subscribed, more like a group of flags. So it's
better to be defined as __u16 (2 bytpes), instead of struct
sctp_event_subscribe (13 bytes).
Note that sctp_event_subscribe is an UAPI struct, used on sockopt
calls, and thus it will not be removed. This patch only changes
the internal storage of the flags.

This patch extends the ncsi-netlink interface with two new commands and
three new attributes to configure multiple packages and/or channels at
once, and configure specific failover modes.
NCSI_CMD_SET_PACKAGE mask and NCSI_CMD_SET_CHANNEL_MASK set a whitelist
of packages or channels allowed to be configured with the
NCSI_ATTR_PACKAGE_MASK and NCSI_ATTR_CHANNEL_MASK attributes
respectively. If one of these whitelists is set only packages or
channels matching the whitelist are considered for the channel queue in
ncsi_choose_active_channel().
These commands may also use the NCSI_ATTR_MULTI_FLAG to signal that
multiple packages or channels may be configured simultaneously. NCSI
hardware arbitration (HWA) must be available in order to enable
multi-package mode. Multi-channel mode is always available.
If the NCSI_ATTR_CHANNEL_ID attribute is present in the
NCSI_CMD_SET_CHANNEL_MASK command the it sets the preferred channel as
with the NCSI_CMD_SET_INTERFACE command. The combination of preferred
channel and channel whitelist defines a primary channel and the allowed
failover channels.
If the NCSI_ATTR_MULTI_FLAG attribute is also present then the preferred
channel is configured for Tx/Rx and the other channels are enabled only
for Rx.

Allow users to set and dump RED flags (ECN enabled and harddrop)
on per-virtual queue basis. Validation of attributes is split
from changes to make sure we won't have to undo previous operations
when we find out configuration is invalid.
The objective is to allow changing per-Qdisc parameters without
overwriting the per-vq configured flags.
Old user space will not pass the TCA_GRED_VQ_FLAGS attribute and
per-Qdisc flags will always get propagated to the virtual queues.
New user space which wants to make use of per-vq flags should set
per-Qdisc flags to 0 and then configure per-vq flags as it
sees fit. Once per-vq flags are set per-Qdisc flags can't be
changed to non-zero. Vice versa - if the per-Qdisc flags are
non-zero the TCA_GRED_VQ_FLAGS attribute has to either be omitted
or set to the same value as per-Qdisc flags.
Update per-Qdisc parameters:
per-Qdisc | per-VQ | result
0 | 0 | all vq flags updated
0 | non-0 | error (vq flags in use)
non-0 | 0 | -- impossible --
non-0 | non-0 | all vq flags updated
Update per-VQ state (flags parameter not specified):
no change to flags
Update per-VQ state (flags parameter set):
per-Qdisc | per-VQ | result
0 | any | per-vq flags updated
non-0 | 0 | -- impossible --
non-0 | non-0 | error (per-Qdisc flags in use)

error -1 is returned to userspace.

Add a new field called fence_fd that will be used by userspace to send
in-fences to the kernel and receive out-fences created by the kernel.
This uapi enables virtio to take advantage of explicit synchronization of
dma-bufs.
There are two new flags:
* VIRTGPU_EXECBUF_FENCE_FD_IN to be used when passing an in-fence fd.
* VIRTGPU_EXECBUF_FENCE_FD_OUT to be used when requesting an out-fence fd
The execbuffer IOCTL is now read-write to allow the userspace to read the
out-fence.
On error -1 should be returned in the fence_fd field.

A new event mask FAN_OPEN_EXEC_PERM has been defined. This allows users
to receive events and grant access to files that are intending to be
opened for execution. Events of FAN_OPEN_EXEC_PERM type will be
generated when a file has been opened by using either execve(),
execveat() or uselib() system calls.
This acts in the same manner as previous permission event mask, meaning
that an access response is required from the user application in order
to permit any further operations on the file.

Similar to 80ba92fa1a92 ("codel: add ce_threshold attribute")
After EDT adoption, it became easier to implement DCTCP-like CE marking.
In many cases, queues are not building in the network fabric but on
the hosts themselves.
If packets leaving fq missed their Earliest Departure Time by XXX usec,
we mark them with ECN CE. This gives a feedback (after one RTT) to
the sender to slow down and find better operating mode.
Example :
tc qd replace dev eth0 root fq ce_threshold 2.5ms

The PTP_SYS_OFFSET ioctl, which can be used to measure the offset
between a PHC and the system clock, includes the total time that the
driver needs to read the PHC timestamp.
This typically involves reading of multiple PCI registers (sometimes in
multiple iterations) and the register that contains the lowest bits of
the timestamp is not read in the middle between the two readings of the
system clock. This asymmetry causes the measured offset to have a
significant error.
Introduce a new ioctl, driver function, and helper functions, which
allow the reading of the lowest register to be isolated from the other
readings in order to reduce the asymmetry. The ioctl returns three
timestamps for each measurement:
- system time right before reading the lowest bits of the PHC timestamp
- PHC time
- system time immediately after reading the lowest bits of the PHC
timestamp

Add a new "peer measurement" API, that can be used to measure
certain things related to a peer. Right now, only implement
FTM (flight time measurement) over it, but the idea is that
it'll be extensible to also support measuring the necessary
things to calculate e.g. angle-of-arrival for WiGig.
The API is structured to have a generic list of peers and
channels to measure with/on, and then for each of those a
set of measurements (again, only FTM right now) to perform.
Results are sent to the requesting socket, including a final
complete message.
Closing the controlling netlink socket will abort a running
measurement.
v3:
- add a bit to report "final" for partial results
- remove list keeping etc. and just unicast out the results
to the requester (big code reduction ...)
- also send complete message unicast, and as a result
remove the multicast group
- separate out struct cfg80211_pmsr_ftm_request_peer
from struct cfg80211_pmsr_request_peer
- document timeout == 0 if no timeout
- disallow setting timeout nl80211 attribute to 0,
must not include attribute for no timeout
- make MAC address randomization optional
- change num bursts exponent default to 0 (1 burst, rather
rather than the old default of 15==don't care)
v4:
- clarify NL80211_ATTR_TIMEOUT documentation
v5:
- remove unnecessary nl80211 multicast/family changes
- remove partial results bit/flag, final is sufficient
- add max_bursts_exponent, max_ftms_per_burst to capability
- rename "frames per burst" -> "FTMs per burst"
v6:
- rename cfg80211_pmsr_free_wdev() to cfg80211_pmsr_wdev_down()
and call it in leave, so the device can't go down with any
pending measurements

on incoming packet to find the corresponding socket that will
receive this packet. Current support for this BPF API is

draft-ietf-nvo3-geneve-08 says:
It is strongly RECOMMENDED that Path MTU Discovery ([RFC1191],
[RFC1981]) be used by setting the DF bit in the IP header when Geneve
packets are transmitted over IPv4 (this is the default with IPv6).
Now that ICMP error handling is working for GENEVE, we can comply with
this recommendation.
Make this configurable, though, to avoid breaking existing setups. By
default, DF won't be set. It can be set or inherited from inner IPv4
packets. If it's configured to be inherited and we are encapsulating IPv6,
it will be set.
This only applies to non-lwt tunnels: if an external control plane is
used, tunnel key will still control the DF flag.

setting only if (!geneve->collect_md) in geneve_xmit_skb()

Allow users to set the IPv4 DF bit in outgoing packets, or to inherit its
value from the IPv4 inner header. If the encapsulated protocol is IPv6 and
DF is configured to be inherited, always set it.
For IPv4, inheriting DF from the inner header was probably intended from
the very beginning judging by the comment to vxlan_xmit(), but it wasn't
actually implemented -- also because it would have done more harm than
good, without handling for ICMP Fragmentation Needed messages.
According to RFC 7348, "Path MTU discovery MAY be used". An expired RFC
draft, draft-saum-nvo3-pmtud-over-vxlan-05, whose purpose was to describe
PMTUD implementation, says that "is a MUST that Vxlan gateways [...]
SHOULD set the DF-bit [...]", whatever that means.
Given this background, the only sane option is probably to let the user
decide, and keep the current behaviour as default.
This only applies to non-lwt tunnels: if an external control plane is
used, tunnel key will still control the DF flag.
v2:
- DF behaviour configuration only applies for non-lwt tunnels, move DF
setting to if (!info) block in vxlan_xmit_one() (Stephen Hemminger)

This is the RX counterpart of commit bec1f6f69736 ("udp: generate gso
with UDP_SEGMENT"). When UDP_GRO is enabled, such socket is also
eligible for GRO in the rx path: UDP segments directed to such socket
are assembled into a larger GSO_UDP_L4 packet.
The core UDP GRO support is enabled with setsockopt(UDP_GRO).
Initial benchmark numbers:
Before:
udp rx: 1079 MB/s 769065 calls/s
After:
udp rx: 1466 MB/s 24877 calls/s
This change introduces a side effect in respect to UDP tunnels:
after a UDP tunnel creation, now the kernel performs a lookup per ingress
UDP packet, while before such lookup happened only if the ingress packet
carried a valid internal header csum.
rfc v2 -> rfc v3:
- fixed typos in macro name and comments
- really enforce UDP_GRO_CNT_MAX, instead of UDP_GRO_CNT_MAX + 1
- acquire socket lock in UDP_GRO setsockopt
rfc v1 -> rfc v2:
- use a new option to enable UDP GRO
- use static keys to protect the UDP GRO socket lookup

We get a headers_check warning about the newly defined ioctl command
structures:
./usr/include/linux/v4l2-controls.h:1105: found __[us]{8,16,32,64} type without #include <linux/types.h>
This is resolved by including linux/types.h, as suggested by the
warning, but there is another problem: Three of the four structures
have an odd number of __u8 headers, but are aligned to 32 bit in the
v4l2_ctrl_mpeg2_slice_params, so we get an implicit padding byte
for each one. To solve that, let's add explicit padding that can
be set to zero and verified in the kernel.

Netfilter fixes for net
The following patchset contains the first batch of Netfilter fixes for
your net tree:
1) Fix splat with IPv6 defragmenting locally generated fragments,
from Florian Westphal.
2) Fix Incorrect check for missing attribute in nft_osf.
3) Missing INT_MIN & INT_MAX definition for netfilter bridge uapi
header, from Jiri Slaby.
4) Revert map lookup in nft_numgen, this is already possible with
the existing infrastructure without this extension.
5) Fix wrong listing of set reference counter, make counter
synchronous again, from Stefano Brivio.
6) Fix CIDR 0 in hash:net,port,net, from Eric Westbrook.
7) Fix allocation failure with large set, use kvcalloc().
From Andrey Ryabinin.
8) No need to disable BH when fetch ip set comment, patch from
Jozsef Kadlecsik.
9) Sanity check for valid sysfs entry in xt_IDLETIMER, from
Taehee Yoo.
10) Fix suspicious rcu usage via ip_set() macro at netlink dump,
from Jozsef Kadlecsik.
11) Fix setting default timeout via nfnetlink_cttimeout, this
comes with preparation patch to add nf_{tcp,udp,...}_pernet()
helper.
12) Allow ebtables table nat to be of filter type via nft_compat.
From Florian Westphal.
13) Incorrect calculation of next bucket in early_drop, do no bump
hash value, update bucket counter instead. From Vasily Khoruzhick.

[Why]
Hardware support for Delta Color Compression (DCC) decompression is
available in DC for GFX9 but there's no way for userspace to enable
the feature.
Enabling the feature can provide improved GFX performance and
power savings in many situations.
[How]
Extend the GFX9 tiling flags to include DCC parameters. These are
logically grouped together with tiling flags even if they are
technically distinct.
This trivially maintains backwards compatibility with existing
users of amdgpu_gem_metadata. No new IOCTls or data structures are
needed to support DCC.
This patch helps expose DCC attributes to both libdrm and amdgpu_dm.

As defined in rfc6525#section-6.1.3, SCTP_STREAM_CHANGE_DENIED
and SCTP_STREAM_CHANGE_FAILED should be used instead of
SCTP_ASSOC_CHANGE_DENIED and SCTP_ASSOC_CHANGE_FAILED.
To keep the compatibility, fix it by adding two macros.

Mali-DP implements a number of tiled yuv formats which are not
currently described in drm_fourcc.h.
This adds those definitions and describes their memory layout by
using the newly added char_per_block, block_w, block_h.

Pull keys updates from James Morris:
"Provide five new operations in the key_type struct that can be used to
provide access to asymmetric key operations. These will be implemented
for the asymmetric key type in a later patch and may refer to a key
retained in RAM by the kernel or a key retained in crypto hardware.
int (*asym_query)(const struct kernel_pkey_params *params,
struct kernel_pkey_query *info);
int (*asym_eds_op)(struct kernel_pkey_params *params,
const void *in, void *out);
int (*asym_verify_signature)(struct kernel_pkey_params *params,
const void *in, const void *in2);
Since encrypt, decrypt and sign are identical in their interfaces,
they're rolled together in the asym_eds_op() operation and there's an
operation ID in the params argument to distinguish them.
Verify is different in that we supply the data and the signature
instead and get an error value (or 0) as the only result on the
expectation that this may well be how a hardware crypto device may
work"
