When binding RFCOMM socket with non-zero channel we're checking if
there is already any other socket which has the same channel number
assigned and then fail. This check does not consider situation where
we have another socket connected to remote device on given channel
number in which case we still should be able to bind local socket.
This patch changes __rfcomm_get_sock_by_addr() to return only sockets
in either BT_BOUND or BT_LISTEN states, also name is updated to better
describe what this function does now.

In current implementation it is possible to reach PF state from unconfirmed.
We can interpret sctp-failover-02 in a way that PF state is meant to be reached
only from active state, in the end, this is when entering PF state makes sense.
Here are few quotes from sctp-failover-02, but regardless of these, same
understanding can be reached from whole section 5:
Section 5.1, quickfailover guide:
"The PF state is an intermediate state between Active and Failed states."
"Each time the T3-rtx timer expires on an active or idle
destination, the error counter of that destination address will
be incremented. When the value in the error counter exceeds
PFMR, the endpoint should mark the destination transport address as PF."
There are several concrete reasons for such interpretation. For start, rfc4960
does not take into concern quickfailover algorithm. Therefore, quickfailover
must comply to 4960. Point where this compliance can be argued is following
behavior:
When PF is entered, association overall error counter is incremented for each
missed HB. This is contradictory to rfc4960, as address, while in unconfirmed
state, is subjected to probing, and while it is probed, it should not increment
association overall error counter. This has as a consequence that we might end
up in situation in which we drop association due path failure on unconfirmed
address, in case we have wrong configuration in a way:
Association.Max.Retrans == Path.Max.Retrans.
Another reason is that entering PF from unconfirmed will cause a loss of address
confirmed event when address is once (if) confirmed. This is fine from failover
guide point of view, but it is not consistent with behavior preceding failover
implementation and recommendation from 4960:
5.4. Path Verification
Whenever a path is confirmed, an indication MAY be given to the upper
layer.

While framing the TDLS Setup Confirmation frame, the driver needs to
know if the TDLS peer is VHT/HT/WMM capable and thus shall construct
the VHT/HT operation / WMM parameter elements accordingly. Supplicant
determines if the TDLS peer is VHT/HT/WMM capable based on the
presence of the respective IEs in the received TDLS Setup Response frame.
The host driver should not need to parse the received TDLS Response
frame and thus, should be able to rely on the supplicant to indicate
the capability of the peer through additional flags while transmitting
the TDLS Setup Confirmation frame through tdls_mgmt operations.

Consider the following (relatively unlikely) scenario:
1) station goes to sleep while frames are buffered in driver
2) driver blocks wakeup (until no more frames are buffered)
3) station wakes up again
4) driver unblocks wakeup
In this case, the current mac80211 code will do the following:
1) WLAN_STA_PS_STA set
2) WLAN_STA_PS_DRIVER set
3) - nothing -
4) WLAN_STA_PS_DRIVER cleared
As a result, no frames will be delivered to the client, even
though it is awake, until it sends another frame to us that
triggers ieee80211_sta_ps_deliver_wakeup() in sta_ps_end().
Since we now take the PS spinlock, we can fix this while at
the same time removing the complexity with the pending skb
queue function. This was broken since my commit 50a9432daeec
("mac80211: fix powersaving clients races") due to removing
the clearing of WLAN_STA_PS_STA in the RX path.
While at it, fix a cleanup path issue when a station is
removed while the driver is still blocking its wakeup.

There's a race condition in mac80211 because we add stations
to the internal lists after adding them to the driver, which
means that (for example) the following can happen:
1. a station connects and is added
2. first, it is added to the driver
3. then, it is added to the mac80211 lists
If the station goes to sleep between steps 2 and 3, and the
firmware/hardware records it as being asleep, mac80211 will
never instruct the driver to wake it up again as it never
realized it went to sleep since the RX path discarded the
frame as a "spurious class 3 frame", no station entry was
present yet.
Fix this by adding the station in software first, and only
then adding it to the driver. That way, any state that the
driver changes will be reflected properly in mac80211's
station state. The problematic part is the roll-back if the
driver fails to add the station, in that case a bit more is
needed. To not make that overly complex prevent starting BA
sessions in the meantime.

There is a race between the TX path and the STA wakeup: while
a station is sleeping, mac80211 buffers frames until it wakes
up, then the frames are transmitted. However, the RX and TX
path are concurrent, so the packet indicating wakeup can be
processed while a packet is being transmitted.
This can lead to a situation where the buffered frames list
is emptied on the one side, while a frame is being added on
the other side, as the station is still seen as sleeping in
the TX path.
As a result, the newly added frame will not be send anytime
soon. It might be sent much later (and out of order) when the
station goes to sleep and wakes up the next time.
Additionally, it can lead to the crash below.
Fix all this by synchronising both paths with a new lock.
Both path are not fastpath since they handle PS situations.
In a later patch we'll remove the extra skb queue locks to
reduce locking overhead.

Currently the kernel tries to announce a zero window when free_space
is below the current receiver mss estimate.
When a sender is transmitting small packets and reader consumes data
slowly (or not at all), receiver might be unable to shrink the receive
win because
a) we cannot withdraw already-commited receive window, and,
b) we have to round the current rwin up to a multiple of the wscale
factor, else we would shrink the current window.
This causes the receive buffer to fill up until the rmem limit is hit.
When this happens, we start dropping packets.
Moreover, tcp_clamp_window may continue to grow sk_rcvbuf towards rmem[2]
even if socket is not being read from.
As we cannot avoid the "current_win is rounded up to multiple of mss"
issue [we would violate a) above] at least try to prevent the receive buf
growth towards tcp_rmem[2] limit by attempting to move to zero-window
announcement when free_space becomes less than 1/16 of the current
allowed receive buffer maximum. If tcp_rmem[2] is large, this will
increase our chances to get a zero-window announcement out in time.
Reproducer:
On server:
$ nc -l -p 12345
<suspend it: CTRL-Z>
Client:
#!/usr/bin/env python
import socket
import time
sock = socket.socket()
sock.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1)
sock.connect(("192.168.4.1", 12345));
while True:
sock.send('A' * 23)
time.sleep(0.005)
socket buffer on server-side will grow until tcp_rmem[2] is hit,
at which point the client rexmits data until -EDTIMEOUT:
tcp_data_queue invokes tcp_try_rmem_schedule which will call
tcp_prune_queue which calls tcp_clamp_window(). And that function will
grow sk->sk_rcvbuf up until it eventually hits tcp_rmem[2].

When a message could not be sent out because the destination node
or link could not be found, the full message size is returned from
sendmsg() as if it had been sent successfully. An application will
then get a false indication that it's making forward progress. This
problem has existed since the initial commit in 2.6.16.
We change this to return -ENETUNREACH if the message cannot be
delivered due to the destination node/link being unavailable. We
also get rid of the redundant tipc_reject_msg call since freeing
the buffer and doing a tipc_port_iovec_reject accomplishes exactly
the same thing.

The only place this is used outside rtnetlink.c is veth. So provide
wrapper function for this usage.

It's slightly smaller/faster for some architectures.
Make sure def_multicast_addr is __aligned(2)

These include are here since kernel 2.2.7, but probably never used.

phy_set_csma_params has a redundant (and impossible) check for
"retries", found by smatch. The check was supposed to be for
frame_retries, but wasn't moved during development when
phy_set_frame_retries was introduced. Also, maxBE >= 3 as required by
the standard is not enforced.
Remove the redundant check, assure max_be >= 3 and check -1 <=
frame_retries <= 7 in the correct function.

At first glance it looks like there is a missing curly brace but
actually the code works the same either way. I have adjusted the
indenting but left the code the same.
