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.

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.

When we introduced GSO support, if using auth the auth chunk was being
left queued on the packet even after the final segment was generated.
Later on sctp_transmit_packet it calls sctp_packet_reset, which zeroed
the packet len while not accounting for this left-over. This caused more
space to be used the next packet due to the chunk still being queued,
but space which wasn't allocated as its size wasn't accounted.
The fix is to only queue it back when we know that we are going to
generate another segment.

====================
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.

hfsc_sched is huge (size: 920, cachelines: 15), but we can get it to 14
cachelines by placing level after filter_cnt (covering 4 byte hole) and
reducing period/nactive/flags to u32 (period is just a counter,
incremented when class becomes active -- 2**32 is plenty for this
purpose, also, long is only 32bit wide on 32bit platforms anyway).
cl_vtperiod is exported to userspace via tc_hfsc_stats, but its period
member is already u32, so no precision is lost there either.

1. the requested block size is smaller than SDIO_BLOCK_SIZE, and/or

Netfilter updates for net-next
The following patchset contains Netfilter updates for net-next,
they are:
1) Don't use userspace datatypes in bridge netfilter code, from
Tobin Harding.
2) Iterate only once over the expectation table when removing the
helper module, instead of once per-netns, from Florian Westphal.
3) Extra sanitization in xt_hook_ops_alloc() to return error in case
we ever pass zero hooks, xt_hook_ops_alloc():
4) Handle NFPROTO_INET from the logging core infrastructure, from
Liping Zhang.
5) Autoload loggers when TRACE target is used from rules, this doesn't
change the behaviour in case the user already selected nfnetlink_log
as preferred way to print tracing logs, also from Liping Zhang.
6) Conntrack slabs with SLAB_HWCACHE_ALIGN to allow rearranging fields
by cache lines, increases the size of entries in 11% per entry.
From Florian Westphal.
7) Skip zone comparison if CONFIG_NF_CONNTRACK_ZONES=n, from Florian.
8) Remove useless defensive check in nf_logger_find_get() from Shivani
Bhardwaj.
9) Remove zone extension as place it in the conntrack object, this is
always include in the hashing and we expect more intensive use of
zones since containers are in place. Also from Florian Westphal.
10) Owner match now works from any namespace, from Eric Bierdeman.
11) Make sure we only reply with TCP reset to TCP traffic from
nf_reject_ipv4, patch from Liping Zhang.
12) Introduce --nflog-size to indicate amount of network packet bytes
that are copied to userspace via log message, from Vishwanath Pai.
This obsoletes --nflog-range that has never worked, it was designed
to achieve this but it has never worked.
13) Introduce generic macros for nf_tables object generation masks.
14) Use generation mask in table, chain and set objects in nf_tables.
This allows fixes interferences with ongoing preparation phase of
the commit protocol and object listings going on at the same time.
This update is introduced in three patches, one per object.
15) Check if the object is active in the next generation for element
deactivation in the rbtree implementation, given that deactivation
happens from the commit phase path we have to observe the future
status of the object.
16) Support for deletion of just added elements in the hash set type.
17) Allow to resize hashtable from /proc entry, not only from the
obscure /sys entry that maps to the module parameter, from Florian
Westphal.
18) Get rid of NFT_BASECHAIN_DISABLED, this code is not exercised
anymore since we tear down the ruleset whenever the netdevice
goes away.
19) Support for matching inverted set lookups, from Arturo Borrero.
20) Simplify the iptables_mangle_hook() by removing a superfluous
extra branch.
21) Introduce ether_addr_equal_masked() and use it from the netfilter
codebase, from Joe Perches.
22) Remove references to "Use netfilter MARK value as routing key"
from the Netfilter Kconfig description given that this toggle
doesn't exists already for 10 years, from Moritz Sichert.
23) Introduce generic NF_INVF() and use it from the xtables codebase,
from Joe Perches.
24) Setting logger to NONE via /proc was not working unless explicit
nul-termination was included in the string. This fixes seems to
leave the former behaviour there, so we don't break backward.

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

Continuing the workaround implemented in commit 23665aaf91
("mac80211: Interoperability workaround for 80+80 and 160 MHz channels")
use the same code to parse the Wide Bandwidth Channel Switch element
by converting to VHT Operation element since the spec also just refers
to that for parsing semantics, particularly with the workaround.
While at it, remove some dead code - the IEEE80211_STA_DISABLE_40MHZ
flag can never be set at this point since it's checked earlier and the
wide_bw_chansw_ie pointer is set to NULL if it's set.

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 radar_detect_widths to the interface combination that allows
concurrent P2P Device dedicated interface and AP interfaces, to enable
testing of radar detection when P2P Device interface is used.
Clear the radar_detect_widths in case of multi channel contexts
as this is not currently supported.
As radar_detect_widths are now supported in all combinations,
remove the hwsim_if_dfs_limits definition since it is no longer
needed.
