The next patch needs 8 bytes in there. sctp_ulpevent has a hole due to
bad alignment; msg_flags is using 4 bytes while it actually uses only 2, so
we shrink it, and iif member (4 bytes) which can be easily fetched from
another place once the next patch is there, so we remove it and thus
creating space for 8 bytes.

We process input path in other files too and having access to it is
nice, so move it to a header where it's shared.

If link is disconnected due to Authentication Failure (PIN or Key
Missing status) userspace will be notified about this with proper error
code. Many LE profiles define "PIN or Key Missing" status as indication
of remote lost bond so this allows userspace to take action on this.

The HCI_BREDR naming is confusing since it actually stands for Primary
Bluetooth Controller. Which is a term that has been used in the latest
standard. However from a legacy point of view there only really have
been Basic Rate (BR) and Enhanced Data Rate (EDR). Recent versions of
Bluetooth introduced Low Energy (LE) and made this terminology a little
bit confused since Dual Mode Controllers include BR/EDR and LE. To
simplify this the name HCI_PRIMARY stands for the Primary Controller
which can be a single mode or dual mode controller.

The RIOT-OS stack does send intra-pan frames but don't set the intra pan
flag inside the mac header. It seems this is valid frame addressing but
inefficient. Anyway this patch adds a new function for intra pan
addressing, doesn't matter if intra pan flag or source and destination
are the same. The newly introduction function will be used to check on
intra pan addressing for 6lowpan.

prsctp PRIO policy is a policy to abandon lower priority chunks when
asoc doesn't have enough snd buffer, so that the current chunk with
higher priority can be queued successfully.
Similar to TTL/RTX policy, we will set the priority of the chunk to
prsctp_param with sinfo->sinfo_timetolive in sctp_set_prsctp_policy().
So if PRIO policy is enabled, msg->expire_at won't work.
asoc->sent_cnt_removable will record how many chunks can be checked to
remove. If priority policy is enabled, when the chunk is queued into
the out_queue, we will increase sent_cnt_removable. When the chunk is
moved to abandon_queue or dequeue and free, we will decrease
sent_cnt_removable.
In sctp_sendmsg, we will check if there is enough snd buffer for current
msg and if sent_cnt_removable is not 0. Then try to abandon chunks in
sctp_prune_prsctp when sendmsg from the retransmit/transmited queue, and
free chunks from out_queue in right order until the abandon+free size >
msg_len - sctp_wfree. For the abandon size, we have to wait until it
sends FORWARD TSN, receives the sack and the chunks are really freed.

prsctp TTL policy is a policy to abandon chunks when they expire
at the specific time in local stack. It's similar with expires_at
in struct sctp_datamsg.
This patch uses sinfo->sinfo_timetolive to set the specific time for
TTL policy. sinfo->sinfo_timetolive is also used for msg->expires_at.
So if prsctp_enable or TTL policy is not enabled, msg->expires_at
still works as before.

This patch adds SCTP_PR_ASSOC_STATUS to sctp sockopt, which is used
to dump the prsctp statistics info from the asoc. The prsctp statistics
includes abandoned_sent/unsent from the asoc. abandoned_sent is the
count of the packets we drop packets from retransmit/transmited queue,
and abandoned_unsent is the count of the packets we drop from out_queue
according to the policy.
Note: another option for prsctp statistics dump described in rfc is
SCTP_PR_STREAM_STATUS, which is used to dump the prsctp statistics
info from each stream. But by now, linux doesn't yet have per stream
statistics info, it needs rfc6525 to be implemented. As the prsctp
statistics for each stream has to be based on per stream statistics,
we will delay it until rfc6525 is done in linux.

This patch adds SCTP_DEFAULT_PRINFO to sctp sockopt. It is used
to set/get sctp Partially Reliable Policies' default params,
which includes 3 policies (ttl, rtx, prio) and their values.
Still, if we set policy params in sndinfo, we will use the params
of sndinfo against chunks, instead of the default params.
In this patch, we will use 5-8bit of sp/asoc->default_flags
to store prsctp policies, and reuse asoc->default_timetolive
to store their values. It means if we enable and set prsctp
policy, prior ttl timeout in sctp will not work any more.

According to section 4.5 of rfc7496, prsctp_enable should be per asoc.
We will add prsctp_enable to both asoc and ep, and replace the places
where it used net.sctp->prsctp_enable with asoc->prsctp_enable.
ep->prsctp_enable will be initialized with net.sctp->prsctp_enable, and
asoc->prsctp_enable will be initialized with ep->prsctp_enable. We can
also modify it's value through sockopt SCTP_PR_SUPPORTED.

As was suggested this patch adds support for the different versions of MLD
and IGMP query types. Since the user visible structure is still in net-next
we can augment it instead of adding netlink attributes.
The distinction between the different IGMP/MLD query types is done as
suggested in Section 7.1, RFC 3376 [1] and Section 8.1, RFC 3810 [2] based
on query payload size and code for IGMP. Since all IGMP packets go through
multicast_rcv() and it uses ip_mc_check_igmp/ipv6_mc_check_mld we can be
sure that at least the ip/ipv6 header can be directly used.

over time there were multiple requests to access different data
structures and fields of task_struct current, so finally add
the helper to access 'current' as-is. Tracing bpf programs will do
the rest of walking the pointers via bpf_probe_read().
Note that current can be null and bpf program has to deal it with,
but even dumb passing null into bpf_probe_read() is still safe.

The routing table of every switch in a tree is currently initialized to
all zeros. This is an issue since 0 is a valid port number.
Add a DSA_RTABLE_NONE=-1 constant to initialize the signed values of the
routing table pointing to other switches.
This fixes the device mapping of the mv88e6xxx driver where the port
pointing to the switch itself and to non-existent switches was wrongly
configured to be 0. It is now set to the expected 0xf value.

rxrpc: Improve conn/call lookup and fix call number generation [ver #3]
I've fixed a couple of patch descriptions and excised the patch that
duplicated the connections list for reconsideration at a later date.
For reference, the excised patch is sitting on the rxrpc-experimental
branch of my git tree, based on top of the rxrpc-rewrite branch. Diffing
it against yesterday's tag shows no differences.
Would you prefer the patch set to be emailed afresh instead of a git-pull
request?

---
Here's the next part of the AF_RXRPC rewrite. The two main purposes of
this set are to fix the call number handling and to make use of RCU when
looking up the connection or call to pass a received packet to.
Important changes in this set include:
(1) Avoidance of placing stack data into SG lists in rxkad so that kernel
stacks can become vmalloc'd (Herbert Xu).
(2) Calls cease pinning the connection they used as soon as possible,
which allows the connection to be discarded sooner and allows the call
channel on that connection to be reused earlier.
(3) Make each call channel on a connection have a separate and independent
call number space rather than having a shared number space for the
connection. Call numbers should increment monotonically per channel
on the client, and the server should ignore a call with a lower call
number for that channel than the latest it has seen. The RESPONSE
packet sets the minimum values of each call ID counter on a
connection.
(4) Look up calls by indexing the channel array on a connection rather
than by keeping calls in an rbtree on that connection. Also look up
calls using the channel array rather than using a hashtable.
The call hashtable can then be removed.
(5) Call terminal statuses are cached in the channel array for the last
call. It is assumed that if we the server have seen call N, then the
client no longer cares about call N-1 on the same channel.
This will allow retransmission of the terminal status in future
without the need to keep the rxrpc_call struct around.
(6) Peer lookups are moved out of common connection handling code and into
service connection handling code as client connections (a) must point
to a peer before they can be used and (b) are looked up by a
machine-unique connection ID directly, so we only need to look up the
peer first if we're going to deal with a service call.
(7) The reference count on a connection is held elevated by 1 whilst it is
alive (ie. idle unused connections have a refcount of 1). The reaper
will attempt to change the refcount from 1->0 and skip if this cannot
be done, whilst look ups only increment the refcount if it's non-zero.
This makes the implementation of RCU lookups easier as we don't have
to get a ref on the connection or a lock on the connection list to
prevent a connection being reaped whilst we're contemplating queueing
a packet that initiates a new service call upon it.
If we need to get a connection, but there's a dead connection in the
tree, we use rb_replace_node() to replace the dead one with a new one.
(8) Use a seqlock to validate the walk over the service connection rbtree
attached to a peer when it's being walked in RCU mode.
(9) Make the incoming call/connection packet handling code use RCU mode
and locks and make it only take a reference if the call/connection
gets queued on a workqueue.
The intention is that the next set will introduce the connection lifetime
management and capacity limits to prevent clients from overloading the
server.
There are some fixes too:
(1) Verifying that a packet coming in to a client connection came from the
expected source.
(2) Fix handling of connection failure in client call creation where we
don't reinitialise the list linkage block and a second attempt to
unlink the failed connection oopses and also we don't set the state
correctly, which causes an assertion failure.
(3) New service calls were being added to the socket's accept queue under
the wrong lock.
Changes:
(V2) In rxrpc_find_service_conn_rcu() initialised the sequence number to 0.
Fixed the RCU handling in conn_service.c by introducing and using
rb_replace_node_rcu() as an RCU-safe alternative in
rxrpc_publish_service_conn().
Modified and used rcu_dereference_raw() to avoid RCU sparse warnings
in rxrpc_find_service_conn_rcu().
Added in some missing RCU dereference wrappers. It seems to be
necessary to turn on CONFIG_PROVE_RCU_REPEATEDLY as well as
CONFIG_SPARSE_RCU_POINTER to get the static __rcu annotation checking
to happen.
Fixed some other sparse warnings, including a missing ntohs() in
jumbo packet processing.
(V3) Fixed some commit descriptions.
Excised the patch that duplicated the connection list to separate out
the procfs list for reconsideration at a later date.

Data structures that are used both with and without RCU protection
are difficult to write in a sparse-clean manner. If you mark the
relevant pointers with __rcu, sparse will complain about all non-RCU
uses, but if you don't mark those pointers, sparse will complain about
all RCU uses.
This commit therefore suppresses sparse warnings for rcu_dereference_raw(),
allowing mixed-protection data structures to avoid these warnings.

Previously, mesh power management functionality works only with kernel
MPM. Because user space MPM did not report mesh peer AID to kernel,
the kernel could not identify the bit in TIM element. So this patch
adds mesh peer AID setting API.

Add the following to support beacon report radio measurement
with the measurement mode field set to passive or active:
1. Propagate the required scan duration to the device
2. Report the scan start time (in terms of TSF)
3. Report each BSS's detection time (also in terms of TSF)
TSF times refer to the BSS that the interface that requested the
scan is connected to.

Beacon report radio measurement requires reporting observed BSSs
on the channels specified in the beacon request. If the measurement
mode is set to passive or active, it requires actually performing a
scan (passive or active, accordingly), and reporting the time that
the scan was started and the time each beacon/probe was received
(both in terms of TSF of the BSS of the requesting AP). If the
request mode is table, this information is optional.
In addition, the radio measurement request specifies the channel
dwell time for the measurement.
In order to use scan for beacon report when the mode is active or
passive, add a parameter to scan request that specifies the
channel dwell time, and add scan start time and beacon received time
to scan results information.
Supporting beacon report is required for Multi Band Operation (MBO).

add API to support VHT MU-MIMO air sniffer.
in MU-MIMO there are parallel frames on the air while the HW
has only one RX.
add the capability to sniff one of the MU-MIMO parallel frames by
giving the sniffer additional information so it'll know which
of the parallel frames it shall follow.
Add attribute - NL80211_ATTR_MU_MIMO_GROUP_DATA - for getting
a MU-MIMO groupID in order to monitor packets from that group
using VHT MU-MIMO.
And add attribute -NL80211_ATTR_MU_MIMO_FOLLOW_ADDR - for passing
MAC address to monitor mode.
that option will be used by VHT MU-MIMO air sniffer to follow a
station according to it's MAC address using VHT MU-MIMO.

Previously, the action frames to group address was not encrypted. But
[1] "Table 8-38 Category values" indicates "Mesh" and "Multihop" category
action frames should be encrypted (Group addressed privacy == yes). And the

People who use PACKET_FANOUT_HASH want a symmetric hash, meaning that
they want packets going in both directions on a flow to hash to the
same bucket.
The core kernel SKB hash became non-symmetric when the ipv6 flow label
and other entities were incorporated into the standard flow hash order
to increase entropy.
But there are no users of PACKET_FANOUT_HASH who want an assymetric
hash, they all want a symmetric one.
Therefore, use the flow dissector to compute a flat symmetric hash
over only the protocol, addresses and ports. This hash does not get
installed into and override the normal skb hash, so this change has
no effect whatsoever on the rest of the stack.

The current implementation does not handle timeout in case of command
with callback request, and this can lead to deadlock if the command
doesn't get fw response.
Add delayed callback timeout work before posting the command to fw.
In case of real fw command completion we will cancel the delayed work.
In case of fw command timeout the callback timeout handler will be
called and it will simulate fw completion with timeout error.

ip_skb_dst_mtu uses skb->sk, assuming it is an AF_INET socket (e.g. it
calls ip_sk_use_pmtu which casts sk as an inet_sk).
However, in the case of UDP tunneling, the skb->sk is not necessarily an
inet socket (could be AF_PACKET socket, or AF_UNSPEC if arriving from
tun/tap).
OTOH, the sk passed as an argument throughout IP stack's output path is
the one which is of PMTU interest:
- In case of local sockets, sk is same as skb->sk;
- In case of a udp tunnel, sk is the tunneling socket.
Fix, by passing ip_finish_output's sk to ip_skb_dst_mtu.
This augments 7026b1ddb6 'netfilter: Pass socket pointer down through okfn().'

This is unusual. Usually IDs listed on early stages of platform

However these IDs here are not listed anymore in any of steppings
and devices IDs tables for Kabylake on configurations overview

So it is better removing them before they become used in any
other future platform.

the hostpc field in struct ehci_regs should be declared as a

When CONFIG_ARM_PMU is disabled, we get the following build error:
arch/arm64/kvm/sys_regs.c: In function 'pmu_counter_idx_valid':
arch/arm64/kvm/sys_regs.c:564:27: error: 'ARMV8_PMU_CYCLE_IDX' undeclared (first use in this function)
if (idx >= val && idx != ARMV8_PMU_CYCLE_IDX)

write_sysreg(ARMV8_PMU_USERENR_MASK, pmuserenr_el0);
This patch fixes the build with CONFIG_ARM_PMU disabled.
