Add support for parsing sink/source pin binding array
per widget from topology. The pin binding arrays will
be used to determine the source and sink queue IDs during
widget binding for widget that requires special pin binding.
An example of widget that requires special pin binding is
the smart amplifier widget, its feedback sink pin has to be
connected to a capture DAI copier for codec feedback, while
the other sink pin has to be connected to a host DAI copier.
Pin ID is required during widget binding for correct route setup.
Conversely, the pin ID for 'generic' pins is not defined in the
topology and will be allocated by the kernel dynamically. When
only one pin is supported, the pin ID shall always be zero. When
more than one pin is supported, the pin ID is determined with the
ID allocation mechanism in the kernel.

aspeed supports differential jpeg format which only compress the parts
which are changed. In this way, it reduces both the amount of data to be
transferred by network and those to be decoded on the client side.
2 new ctrls are added:
* Aspeed HQ Mode: to control aspeed's high quality(2-pass) compression mode
This only works with yuv444 subsampling.
* Aspeed HQ Quality: to control the quality of aspeed's HQ mode
only useful if Aspeed HQ mode is enabled
Aspeed JPEG Format requires an additional buffer, called bcd, to store
the information about which macro block in the new frame is different
from the previous one.
To have bcd correctly working, we need to swap the buffers for src0/1 to
make src1 refer to previous frame and src0 to the coming new frame.

This introduces support for the Aspeed JPEG format, where the new frame
can refer to previous frame to reduce the amount of compressed data.
The concept is similar to I/P frame of video compression. It will
compare the new frame with previous one to decide which macroblock's
data is changed, and only the changed macroblocks will be compressed.
This Aspeed JPEG format is used by the video engine on Aspeed platforms,
which is generally adapted for remote KVM.

Hosts that support 802.1X authentication are able to authenticate
themselves by exchanging EAPOL frames with an authenticator (Ethernet
bridge, in this case) and an authentication server. Access to the
network is only granted by the authenticator to successfully
authenticated hosts.
The above is implemented in the bridge using the "locked" bridge port
option. When enabled, link-local frames (e.g., EAPOL) can be locally
received by the bridge, but all other frames are dropped unless the host
is authenticated. That is, unless the user space control plane installed
an FDB entry according to which the source address of the frame is
located behind the locked ingress port. The entry can be dynamic, in
which case learning needs to be enabled so that the entry will be
refreshed by incoming traffic.
There are deployments in which not all the devices connected to the
authenticator (the bridge) support 802.1X. Such devices can include
printers and cameras. One option to support such deployments is to
unlock the bridge ports connecting these devices, but a slightly more
secure option is to use MAB. When MAB is enabled, the MAC address of the
connected device is used as the user name and password for the
authentication.
For MAB to work, the user space control plane needs to be notified about
MAC addresses that are trying to gain access so that they will be
compared against an allow list. This can be implemented via the regular
learning process with the sole difference that learned FDB entries are
installed with a new "locked" flag indicating that the entry cannot be
used to authenticate the device. The flag cannot be set by user space,
but user space can clear the flag by replacing the entry, thereby
authenticating the device.
Locked FDB entries implement the following semantics with regards to
roaming, aging and forwarding:
1. Roaming: Locked FDB entries can roam to unlocked (authorized) ports,
in which case the "locked" flag is cleared. FDB entries cannot roam
to locked ports regardless of MAB being enabled or not. Therefore,
locked FDB entries are only created if an FDB entry with the given {MAC,
VID} does not already exist. This behavior prevents unauthenticated
devices from disrupting traffic destined to already authenticated
devices.
2. Aging: Locked FDB entries age and refresh by incoming traffic like
regular entries.
3. Forwarding: Locked FDB entries forward traffic like regular entries.
If user space detects an unauthorized MAC behind a locked port and
wishes to prevent traffic with this MAC DA from reaching the host, it
can do so using tc or a different mechanism.
Enable the above behavior using a new bridge port option called "mab".
It can only be enabled on a bridge port that is both locked and has
learning enabled. Locked FDB entries are flushed from the port once MAB
is disabled. A new option is added because there are pure 802.1X
deployments that are not interested in notifications about locked FDB
entries.

Add new apptrust extension attributes to the 8021Qaz APP managed object.
Two new attributes, DCB_ATTR_DCB_APP_TRUST_TABLE and
DCB_ATTR_DCB_APP_TRUST, has been added. Trusted selectors are passed in
the nested attribute DCB_ATTR_DCB_APP_TRUST, in order of precedence.
The new attributes are meant to allow drivers, whose hw supports the
notion of trust, to be able to set whether a particular app selector is
trusted - and in which order.

Add new PCP selector for the 8021Qaz APP managed object.
As the PCP selector is not part of the 8021Qaz standard, a new non-std
extension attribute DCB_ATTR_DCB_APP has been introduced. Also two
helper functions to translate between selector and app attribute type
has been added. The new selector has been given a value of 255, to
minimize the risk of future overlap of std- and non-std attributes.
The new DCB_ATTR_DCB_APP is sent alongside the ieee std attribute in the
app table. This means that the dcb_app struct can now both contain std-
and non-std app attributes. Currently there is no overlap between the
selector values of the two attributes.
The purpose of adding the PCP selector, is to be able to offload
PCP-based queue classification to the 8021Q Priority Code Point table,
see 6.9.3 of IEEE Std 802.1Q-2018.
PCP and DEI is encoded in the protocol field as 8*dei+pcp, so that a
mapping of PCP 2 and DEI 1 to priority 3 is encoded as {255, 10, 3}.

Extend packet socket option PACKET_IGNORE_OUTGOING to fanout groups.
The socket option sets ptype.ignore_outgoing, which makes
dev_queue_xmit_nit skip the socket.
When the socket joins a fanout group, the option is not reflected in
the struct ptype of the group. dev_queue_xmit_nit only tests the
fanout ptype, so the flag is ignored once a socket joins a
fanout group.
Inheriting the option from a socket would change established behavior.
Different sockets in the group can set different flags, and can also
change them at runtime.
Testing in packet_rcv_fanout defeats the purpose of the original
patch, which is to avoid skb_clone in dev_queue_xmit_nit (esp. for
MSG_ZEROCOPY packets).
Instead, introduce a new fanout group flag with the same behavior.

We want to leverage keyring to store sensitive keys, and then use those
keys for symmetric encryption via the crypto API. Among the key types we
wish to support are: user, logon, encrypted, and trusted.
User key types are already able to have their data copied to user space,
but logon does not support this. Further, trusted and encrypted keys will
return their encrypted data back to user space on read, which does not
make them ideal for symmetric encryption.
To support symmetric encryption for these key types, add a new
ALG_SET_KEY_BY_KEY_SERIAL setsockopt() option to the crypto API. This
allows users to pass a key_serial_t to the crypto API to perform
symmetric encryption. The behavior is the same as ALG_SET_KEY, but
the crypto key data is copied in kernel space from a keyring key,
which allows for the support of logon, encrypted, and trusted key types.
Keyring keys must have the KEY_(POS|USR|GRP|OTH)_SEARCH permission set
to leverage this feature. This follows the asymmetric_key type where key
lookup calls eventually lead to keyring_search_rcu() without the
KEYRING_SEARCH_NO_CHECK_PERM flag set.

====================
Netfilter updates for net-next
1) Move struct nft_payload_set definition to .c file where it is
only used.
2) Shrink transport and inner header offset fields in the nft_pktinfo
structure to 16-bits, from Florian Westphal.
3) Get rid of nft_objref Kbuild toggle, make it built-in into
nf_tables. This expression is used to instantiate conntrack helpers
in nftables. After removing the conntrack helper auto-assignment
toggle it this feature became more important so move it to the nf_tables
core module. Also from Florian.
4) Extend the existing function to calculate payload inner header offset
to deal with the GRE and IPIP transport protocols.
6) Add inner expression support for nf_tables. This new expression
provides a packet parser for tunneled packets which uses a userspace
description of the expected inner headers. The inner expression
invokes the payload expression (via direct call) to match on the
inner header protocol fields using the inner link, network and
transport header offsets.
An example of the bytecode generated from userspace to match on
IP source encapsulated in a VxLAN packet:
# nft --debug=netlink add rule netdev x y udp dport 4789 vxlan ip saddr 1.2.3.4
netdev x y
[ meta load l4proto => reg 1 ]
[ cmp eq reg 1 0x00000011 ]
[ payload load 2b @ transport header + 2 => reg 1 ]
[ cmp eq reg 1 0x0000b512 ]
[ inner type vxlan hdrsize 8 flags f [ meta load protocol => reg 1 ] ]
[ cmp eq reg 1 0x00000008 ]
[ inner type vxlan hdrsize 8 flags f [ payload load 4b @ network header + 12 => reg 1 ] ]
[ cmp eq reg 1 0x04030201 ]
7) Store inner link, network and transport header offsets in percpu
area to parse inner packet header once only. Matching on a different
tunnel type invalidates existing offsets in the percpu area and it
invokes the inner tunnel parser again.
8) Add support for inner meta matching. This support for
NFTA_META_PROTOCOL, which specifies the inner ethertype, and
NFT_META_L4PROTO, which specifies the inner transport protocol.
9) Extend nft_inner to parse GENEVE optional fields to calculate the
link layer offset.
10) Update inner expression so tunnel offset points to GRE header
to normalize tunnel header handling. This also allows to perform
different interpretations of the GRE header from userspace.

OA reports in the OA buffer contain an OA timestamp field that helps
user calculate delta between 2 OA reports. The calculation relies on the
CS timestamp frequency to convert the timestamp value to nanoseconds.
The CS timestamp frequency is a function of the CTC_SHIFT value in
RPM_CONFIG0.
In DG2, OA unit assumes that the CTC_SHIFT is 3, instead of using the
actual value from RPM_CONFIG0. At the user level, this results in an
error in calculating delta between 2 OA reports since the OA timestamp
is not shifted in the same manner as CS timestamp. Also the periodicity
of the reports is different from what the user configured because of
mismatch in the CS and OA frequencies.
The issue also affects MI_REPORT_PERF_COUNT command.
To resolve this, return actual OA timestamp frequency to the user in
i915_getparam_ioctl, so that user can calculate the right OA exponent as
well as interpret the reports correctly.

Similar to sk/inode/task storage, implement similar cgroup local storage.
There already exists a local storage implementation for cgroup-attached
bpf programs. See map type BPF_MAP_TYPE_CGROUP_STORAGE and helper
bpf_get_local_storage(). But there are use cases such that non-cgroup
attached bpf progs wants to access cgroup local storage data. For example,
tc egress prog has access to sk and cgroup. It is possible to use
sk local storage to emulate cgroup local storage by storing data in socket.
But this is a waste as it could be lots of sockets belonging to a particular
cgroup. Alternatively, a separate map can be created with cgroup id as the key.
But this will introduce additional overhead to manipulate the new map.
A cgroup local storage, similar to existing sk/inode/task storage,
should help for this use case.
The life-cycle of storage is managed with the life-cycle of the
cgroup struct. i.e. the storage is destroyed along with the owning cgroup
with a call to bpf_cgrp_storage_free() when cgroup itself
is deleted.
The userspace map operations can be done by using a cgroup fd as a key
passed to the lookup, update and delete operations.
Typically, the following code is used to get the current cgroup:
struct task_struct *task = bpf_get_current_task_btf();
... task->cgroups->dfl_cgrp ...
and in structure task_struct definition:
struct task_struct {
....
struct css_set __rcu *cgroups;
....
}
With sleepable program, accessing task->cgroups is not protected by rcu_read_lock.
So the current implementation only supports non-sleepable program and supporting
sleepable program will be the next step together with adding rcu_read_lock
protection for rcu tagged structures.
Since map name BPF_MAP_TYPE_CGROUP_STORAGE has been used for old cgroup local
storage support, the new map name BPF_MAP_TYPE_CGRP_STORAGE is used
for cgroup storage available to non-cgroup-attached bpf programs. The old
cgroup storage supports bpf_get_local_storage() helper to get the cgroup data.
The new cgroup storage helper bpf_cgrp_storage_get() can provide similar
functionality. While old cgroup storage pre-allocates storage memory, the new
mechanism can also pre-allocate with a user space bpf_map_update_elem() call
to avoid potential run-time memory allocation failure.
Therefore, the new cgroup storage can provide all functionality w.r.t.
the old one. So in uapi bpf.h, the old BPF_MAP_TYPE_CGROUP_STORAGE is alias to
BPF_MAP_TYPE_CGROUP_STORAGE_DEPRECATED to indicate the old cgroup storage can
be deprecated since the new one can provide the same functionality.

This new expression allows you to match on the inner headers that are
encapsulated by any of the existing tunneling protocols.
This expression parses the inner packet to set the link, network and
transport offsets, so the existing expressions (with a few updates) can
be reused to match on the inner headers.
The inner expression supports for different tunnel combinations such as:
- ethernet frame over IPv4/IPv6 packet, eg. VxLAN.
- IPv4/IPv6 packet over IPv4/IPv6 packet, eg. IPIP.
- IPv4/IPv6 packet over IPv4/IPv6 + transport header, eg. GRE.
- transport header (ESP or SCTP) over transport header (usually UDP)
The following fields are used to describe the tunnel protocol:
- flags, which describe how to parse the inner headers:
NFT_PAYLOAD_CTX_INNER_TUN, the tunnel provides its own header.
NFT_PAYLOAD_CTX_INNER_ETHER, the ethernet frame is available as inner header.
NFT_PAYLOAD_CTX_INNER_NH, the network header is available as inner header.
NFT_PAYLOAD_CTX_INNER_TH, the transport header is available as inner header.
For example, VxLAN sets on all of these flags. While GRE only sets on
NFT_PAYLOAD_CTX_INNER_NH and NFT_PAYLOAD_CTX_INNER_TH. Then, ESP over
UDP only sets on NFT_PAYLOAD_CTX_INNER_TH.
The tunnel description is composed of the following attributes:
- header size: in case the tunnel comes with its own header, eg. VxLAN.
- type: this provides a hint to userspace on how to delinearize the rule.
This is useful for VxLAN and Geneve since they run over UDP, since
transport does not provide a hint. This is also useful in case hardware
offload is ever supported. The type is not currently interpreted by the
kernel.
- expression: currently only payload supported. Follow up patch adds
also inner meta support which is required by autogenerated
dependencies. The exthdr expression should be supported too
at some point. There is a new inner_ops operation that needs to be
set on to allow to use an existing expression from the inner expression.
This patch adds a new NFT_PAYLOAD_TUN_HEADER base which allows to match
on the tunnel header fields, eg. vxlan vni.
The payload expression is embedded into nft_inner private area and this
private data area is passed to the payload inner eval function via
direct call.

Internally the control framework handles such arrays just fine, but

The internal union v4l2_ctrl_ptr which the control framework uses already
