Header-less cloned skbs with sufficient headroom need not be cloned
unless the tailroom is going to be modified.
Fix ieee80211_skb_resize so it would only resize cloned skbs if either
the header isn't released or the tailroom is going to be modified.
Some drivers might have assumed that skbs are never cloned, so add a HW
flag that explicitly permits cloned TX skbs. Drivers which do not modify
TX skbs should set this flag to avoid copying skbs.

In the cfg80211_rx_mgmt(), parameter @gfp was used for the memory allocation.
But, memory get allocated under spin_lock_bh(), this implies atomic context.
So, one can't use GFP_KERNEL, only variants with no __GFP_WAIT. Actually, in all
occurrences GFP_ATOMIC is used (wil6210 use GFP_KERNEL by mistake),
and it should be this way or warning triggered in the memory allocation code.
Remove @gfp parameter as no actual choice exist, and use hard coded
GFP_ATOMIC for memory allocation.

The 802.11 standard says when processing a plink confirm
frame:
"If the peerLinkID in the mesh peering instance has not been
set, the Local Link ID field of the Mesh Peering Confirm
request shall be copied into the peerLinkID in the mesh
peering instance."
We were only doing this when receiving an open peering frame,
but it could happen that the open frame gets lost and so we
should handle this case rather than rejecting the confirm and
failing the whole peering process.

This reverts commit 24aa11ab8ae03292d38ec0dbd9bc2ac49fe8a6dd.
That commit was wrong since it uses data that hasn't even been set
up yet, but might be a hold-over from a previous connection.
Additionally, it seems like a driver-specific workaround that
shouldn't have been in mac80211 to start with.

- check for net_ns before creating / deleting symlink.
for now only netdev_adjacent_rename_links and

__netdev_adjacent_dev_insert implies both net_devs

Drivers, and perhaps other entities we have not yet considered,
sometimes want to know how deep the protocol headers go before
deciding how large of an SKB to allocate and how much of the packet to
place into the linear SKB area.
For example, consider a driver which has a device which DMAs into
pools of pages and then tells the driver where the data went in the
DMA descriptor(s). The driver can then build an SKB and reference
most of the data via SKB fragments (which are page/offset/length
triplets).
However at least some of the front of the packet should be placed into
the linear SKB area, which comes before the fragments, so that packet
processing can get at the headers efficiently. The first thing each
protocol layer is going to do is a "pskb_may_pull()" so we might as
well aggregate as much of this as possible while we're building the
SKB in the driver.
Part of supporting this is that we don't have an SKB yet, so we want
to be able to let the flow dissector operate on a raw buffer in order
to compute the offset of the end of the headers.
So now we have a __skb_flow_dissect() which takes an explicit data
pointer and length.

In previous commits we have reduced usage of port_lock to a minimum,
and complemented it with usage of bh_lock_sock() at the remaining
locations. The purpose has been to remove this lock altogether, since
it largely duplicates the role of bh_lock_sock. We are now ready to do
this.
However, we still need to protect the BH callers from inadvertent
release of the socket while they hold a reference to it. We do this by
replacing port_lock by a combination of a rw-lock protecting the
reference table as such, and updating the socket reference counter while
the socket is referenced from BH. This technique is more standard and
comprehensible than the previous approach, and turns out to have a
positive effect on overall performance.

In order to make tipc_sock the only entity referencable from other
parts of the stack, we add a tipc_sock pointer instead of a tipc_port
pointer to the registry. As a consequence, we also let the function
tipc_port_lock() return a pointer to a tipc_sock instead of a tipc_port.
We keep the function's name for now, since the lock still is owned by
the port.
This is another step in the direction of eliminating port_lock, replacing
its usage with lock_sock() and bh_lock_sock().

The functions tipc_port_get_ports() and tipc_port_reinit() scan over
all sockets/ports to access each of them. This is done by using a
dedicated linked list, 'tipc_socks' where all sockets are members. The
list is in turn protected by a spinlock, 'port_list_lock', while each
socket is locked by using port_lock at the moment of access.
In order to reduce complexity and risk of deadlock, we want to get
rid of the linked list and the accompanying spinlock.
This is what we do in this commit. Instead of the linked list, we use
the port registry to scan across the sockets. We also add usage of
bh_lock_sock() inside the scope of port_lock in both functions, as a
preparation for the complete removal of port_lock.
Finally, we move the functions from port.c to socket.c, and rename them
to tipc_sk_sock_show() and tipc_sk_reinit() repectively.

After the latest changes to the socket/port layer the existence of
the functions tipc_port_init() and tipc_port_destroy() cannot be
justified. They are both called only once, from tipc_sk_create() and
tipc_sk_delete() respectively, and their functionality can better be
merged into the latter two functions.
This also entails that all remaining references to port_lock now are
made from inside socket.c, something that will make it easier to remove
this lock.

The function tipc_acknowledge() is a remnant from the obsolete native

message and sending it to the peer.
Since all access to socket members now is protected by the socket lock,
it has become unnecessary to grab port_lock here.

tipc_port_connect()/tipc_port_disconnect() are remnants of the obsolete
native API. Their only task is to grab port_lock and call the functions
__tipc_port_connect()/__tipc_port_disconnect() respectively, which will
perform the actual state change.
Since socket/port exection now is single-threaded the use of port_lock
is not needed any more, so we can safely replace the two functions with
their lock-free counterparts.
In this commit, we remove the two functions. Furthermore, the contents
of __tipc_port_disconnect() is so trivial that we choose to eliminate
that function too, expanding its functionality into tipc_shutdown().
__tipc_port_connect() is simplified, moved to socket.c, and given the
more correct name tipc_sk_finish_conn(). Finally, we eliminate the
function auto_connect(), and expand its contents into filter_connect().

tipc_port_shutdown() is a remnant from the now obsolete native
interface. As such it grabs port_lock in order to protect itself
from concurrent BH processing.
However, after the recent changes to the port/socket upcalls, sockets
are now basically single-threaded, and all execution, except the read-only
tipc_sk_timer(), is executing within the protection of lock_sock(). So
the use of port_lock is not needed here.
In this commit we eliminate the whole function, and merge it into its
only caller, tipc_shutdown().

The last remaining BH upcall to the socket, apart for the message
reception function tipc_sk_rcv(), is the timer function.
We prefer to let this function continue executing in BH, since it only
does read-acces to semi-permanent data, but we make three changes to it:
1) We introduce a bh_lock_sock()/bh_unlock_sock() inside the scope
of port_lock. This is a preparation for replacing port_lock with
bh_lock_sock() at the locations where it is still used.
2) We move the function from port.c to socket.c, as a further step
of eliminating the port code level altogether.
3) We let it make use of the newly introduced tipc_msg_create()
