There are several instances where a pskb_copy or __pskb_copy is
immediately followed by an skb_clone.
Add a couple of new functions to allow the copy skb to be allocated
from the fclone cache and thus speed up subsequent skb_clone calls.

-[0x01 Introduction
We have found a programming error causing a deadlock in Bluetooth subsystem
of Linux kernel. The problem is caused by missing release_sock() call when
L2CAP connection creation fails due full accept queue.
The issue can be reproduced with 3.15-rc5 kernel and is also present in
earlier kernels.
-[0x02 Details
The problem occurs when multiple L2CAP connections are created to a PSM which
contains listening socket (like SDP) and left pending, for example,
configuration (the underlying ACL link is not disconnected between
connections).
When L2CAP connection request is received and listening socket is found the
l2cap_sock_new_connection_cb() function (net/bluetooth/l2cap_sock.c) is called.
This function locks the 'parent' socket and then checks if the accept queue
is full.
1178 lock_sock(parent);
1179
1180 /* Check for backlog size */
1181 if (sk_acceptq_is_full(parent)) {
1182 BT_DBG("backlog full %d", parent->sk_ack_backlog);
1183 return NULL;
1184 }
If case the accept queue is full NULL is returned, but the 'parent' socket
is not released. Thus when next L2CAP connection request is received the code
blocks on lock_sock() since the parent is still locked.
Also note that for connections already established and waiting for
configuration to complete a timeout will occur and l2cap_chan_timeout()
(net/bluetooth/l2cap_core.c) will be called. All threads calling this
function will also be blocked waiting for the channel mutex since the thread
which is waiting on lock_sock() alread holds the channel mutex.
We were able to reproduce this by sending continuously L2CAP connection
request followed by disconnection request containing invalid CID. This left
the created connections pending configuration.
After the deadlock occurs it is impossible to kill bluetoothd, btmon will not
get any more data etc. requiring reboot to recover.
-[0x03 Fix
Releasing the 'parent' socket when l2cap_sock_new_connection_cb() returns NULL
seems to fix the issue.

Due to recent changes to the way that the MITM requirement is set for
outgoing pairing attempts we can no longer rely on the hcon->auth_type
variable (which is actually good since it was formed from BR/EDR
concepts that don't really exist for SMP).
To match the logic that BR/EDR now uses simply rely on the local IO
capability and/or needed security level to set the MITM requirement for
outgoing pairing requests.

The universal/local bit handling was incorrectly done in the code.
So when setting EUI address from BD address we do this:
- If BD address type is PUBLIC, then we clear the universal bit
in EUI address. If the address type is RANDOM, then the universal
bit is set (BT 6lowpan draft chapter 3.2.2)
- After this we invert the universal/local bit according to RFC 2464
When figuring out BD address we do the reverse:
- Take EUI address from stateless IPv6 address, invert the
universal/local bit according to RFC 2464
- If universal bit is 1 in this modified EUI address, then address
type is set to RANDOM, otherwise it is PUBLIC
Note that 6lowpan_iphc.[ch] does the final toggling of U/L bit
before sending or receiving the network packet.

On the mgmt level we have a key type parameter which currently accepts
two possible values: 0x00 for unauthenticated and 0x01 for
authenticated. However, in the internal struct smp_ltk representation we
have an explicit "authenticated" boolean value.
To make this distinction clear, add defines for the possible mgmt values
and do conversion to and from the internal authenticated value.

our own code to call smp_failure().

When the SMP code was initially created (mid-2011) parts of the
Bluetooth subsystem were still not converted to use workqueues. This
meant that the crypto calls, which could sleep, couldn't be called
directly. Because of this the "confirm" and "random" work structs were
introduced.
These days the entire Bluetooth subsystem runs through workqueues which
makes these structs unnecessary. This patch removes them and converts
the calls to queue them to use direct function calls instead.

There are no users of the smp_chan struct outside of smp.c so move it
away from smp.h. The addition of the l2cap.h include to hci_core.c,
hci_conn.c and mgmt.c is something that should have been there already
previously to avoid warnings of undeclared struct l2cap_conn, but the
compiler warning was apparently shadowed away by the mention of
l2cap_conn in the struct smp_chan definition.

When we're performing reauthentication (in order to elevate the
security level from an unauthenticated key to an authenticated one) we
do not need to issue any encryption command once authentication
completes. Since the trigger for the encryption HCI command is the
ENCRYPT_PEND flag this flag should not be set in this scenario.
Instead, the REAUTH_PEND flag takes care of all necessary steps for
reauthentication.

Commit 1c2e004183178 introduced an event handler for the encryption key
refresh complete event with the intent of fixing some LE/SMP cases.
However, this event is shared with BR/EDR and there we actually want to
act only on the auth_complete event (which comes after the key refresh).
If we do not do this we may trigger an L2CAP Connect Request too early
and cause the remote side to return a security block error.

Several spots in the kernel perform a sequence like:
skb_queue_tail(&sk->s_receive_queue, skb);
sk->sk_data_ready(sk, skb->len);
But at the moment we place the SKB onto the socket receive queue it
can be consumed and freed up. So this skb->len access is potentially
to freed up memory.
Furthermore, the skb->len can be modified by the consumer so it is
possible that the value isn't accurate.
And finally, no actual implementation of this callback actually uses
the length argument. And since nobody actually cared about it's
value, lots of call sites pass arbitrary values in such as '0' and
even '1'.
So just remove the length argument from the callback, that way there
is no confusion whatsoever and all of these use-after-free cases get
fixed as a side effect.
Based upon a patch by Eric Dumazet and his suggestion to audit this
issue tree-wide.

The GAP Specification gives the flexibility to decide whether MITM
Protection is requested or not (Bluetooth Core Specification v4.0
Volume 3, part C, section 6.5.3) when replying to an
HCI_EV_IO_CAPA_REQUEST event.
The recommendation is *not* to set this flag "unless the security
policy of an available local service requires MITM Protection"
(regardless of the bonding type). However, the kernel doesn't
necessarily have this information and therefore the safest choice is
to always use MITM Protection, also for General Bonding.
This patch changes the behavior for the General Bonding initiator
role, always requesting MITM Protection even if no high security level
is used. Depending on the remote capabilities, the protection might
not be actually used, and we will accept this locally unless of course
a high security level was originally required.
Note that this was already done for Dedicated Bonding. No-Bonding is
left unmodified because MITM Protection is normally not desired in
these cases.

When responding to a remotely-initiated pairing procedure, a MITM
protected SSP associaton model can be used for pairing if both local
and remote IO capabilities are set to something other than
NoInputNoOutput, regardless of the bonding type (Dedicated or
General).
This was already done for Dedicated Bonding but this patch proposes to
use the same policy for General Bonding as well.
The GAP Specification gives the flexibility to decide whether MITM
Protection is used ot not (Bluetooth Core Specification v4.0 Volume 3,
part C, section 6.5.3).
Note however that the recommendation is *not* to set this flag "unless
the security policy of an available local service requires MITM
Protection" (for both Dedicated and General Bonding). However, as we are
already requiring MITM for Dedicated Bonding, we will follow this
behaviour also for General Bonding.

Do not always set the MITM protection requirement by default in the

When sending out a device found event caused by an advertising report in
the situation where we couldn't store the report as a pending one, the
code was incorrectly trying to use the address and address type from the
pending data. Since the pending data is cleared in the previous line
this causes a potentially incorrect address type and an address of
BDADDR_ANY. This patch fixes the call to use the address information
correctly from the received advertising report.
