When accepting a pairing request which fulfills the SSP auto-accept
criteria we need to push the request all the way to the user for
confirmation. This patch adds a new hint to the user_confirm_request
management event so user space can know when to show a numeric
comparison dialog and when to show a simple yes/no confirmation dialog.

Some test systems require an arbitrary delay to the auto-accept test
cases for Secure Simple Pairing in order for the tests to pass.
Previously when this was handled in user space it was worked around by
code modifications and recompilation, but now that it's on the kernel
side it's more convenient if there's a debugfs interface for it.

This patch adds automated negative and positive (auto-accept) responses
for Secure Simple Pairing user confirmation requests. The responses are
only sent if the HCI_MGMT flag is set in order not to confuse older user

In xmit path, devices that do full hardware crypto (including
TKIP MMIC) need no tailroom. For such devices, tailroom
reservation can be skipped if all the keys are programmed into
the hardware (i.e software crypto is not used for any of the
keys) and none of the keys wants software to generate Michael
MIC.

High security level for pre v2.1 devices requires combination link key
authenticated by at least 16 digit PIN code.
It's also necessary to update key_type and pin_length when the key
exists and is sufficently secured for the connection as there will be
no link key notify event in that case.

If authentication fails the security level should stay as it was set
before the process has started. Setting BT_SECURITY_LOW can hide real
security level on a link eg. having BT_SECURITY_MEDIUM on the link,
re-authenticate with failure to get BT_SECURITY_HIGH, as a result we
get BT_SECURITY_LOW on the link while the real security is still medium.

In order to speedup packet filtering, here is an implementation of a
JIT compiler for x86_64
It is disabled by default, and must be enabled by the admin.
echo 1 >/proc/sys/net/core/bpf_jit_enable
It uses module_alloc() and module_free() to get memory in the 2GB text
kernel range since we call helpers functions from the generated code.
EAX : BPF A accumulator
EBX : BPF X accumulator
RDI : pointer to skb (first argument given to JIT function)
RBP : frame pointer (even if CONFIG_FRAME_POINTER=n)
r9d : skb->len - skb->data_len (headlen)
r8 : skb->data
To get a trace of generated code, use :
echo 2 >/proc/sys/net/core/bpf_jit_enable
Example of generated code :
# tcpdump -p -n -s 0 -i eth1 host 192.168.20.0/24

Output route resolution never returns a route with rt_src set to zero
(which is INADDR_ANY).
Even if the flow key for the output route lookup specifies INADDR_ANY
for the source address, the output route resolution chooses a real
source address to use in the final route.
This test has existed forever in igmp_send_report() and David Stevens
simply copied over the erroneous test when implementing support for
IGMPv3.

These functions are used together as a unit for route resolution
during connect(). They address the chicken-and-egg problem that
exists when ports need to be allocated during connect() processing,
yet such port allocations require addressing information from the
routing code.
It's currently more heavy handed than it needs to be, and in
particular we allocate and initialize a flow object twice.
Let the callers provide the on-stack flow object. That way we only
need to initialize it once in the ip_route_connect() call.
Later, if ip_route_newports() needs to do anything, it re-uses that
flow object as-is except for the ports which it updates before the
route re-lookup.
Also, describe why this set of facilities are needed and how it works
in a big comment.

The ipv6 routing lookup does give us a source address,
but instead of filling it into the dst, it's stored in
the flowi. We can use that instead of going through the
entire source address selection again.

root cause:
Node-A and Node-B use the source address routing, and
at begining, source address will be NULL,sctp will
search the routing table by the destination address,
because using the source address routing table, and
the result dst_entry will be NULL.
solution:
walk through the bind address list to get the source
address and then lookup the routing table again to get
the correct dst_entry.

The patch "cfg80211: add a timer for invalid user reg hints"
introduced a regression for the case where a secondary identical
regulatory hint from a user is sent. What would happen is the
second hint would schedule delayed work in to catch a timeout
but since we are never processing it given that the hint was already
applied we'd always hit the timeout and and restore regulatory
settings back to world regulatory domain. This is fixed by simply
avoiding sheduling work if the hint was already applied.

Since now when bonding uses rx_handler, all traffic going into bond
device goes thru bond_handle_frame. So there's no need to go back into
bonding code later via ptype handlers. This patch converts
original ptype handlers into "bonding receive probes". These functions
are called from bond_handle_frame and they are registered per-mode.
Note that vlan packets are also handled because they are always untagged
thanks to vlan_untag()
Note that this also allows arpmon for eth-bond-bridge-vlan topology.

The oops happens in dst_metrics_write_ptr()
include/net/dst.h:124: return dst->ops->cow_metrics(dst, p);
dst->ops->cow_metrics is NULL and causes the oops.
Provide cow_metrics() methods, like we did in commit 214f45c91bb
(net: provide default_advmss() methods to blackhole dst_ops)

Currently mac80211 uses ieee80211_disable_40mhz_24ghz module
parameter to allow disabling 40MHz operation in the 2.4GHz band.
Move this handling from mac80211 to cfg80211 so that the feature
will be more generic.

Currently, the code to tear down BA sessions will
execute after queues are stopped, but attempt to
send frames, so those frames will just get queued,
which isn't intended. Move this code to before to
tear down the sessions properly.
Additionally, after stopping queues, flush the TX
queues in the driver driver to make sure all the
frames went out.
