Starting with version 4.5, GCC has a new built-in function
__builtin_unreachable() that can be used in places like the kernel's
BUG() where inline assembly is used to transfer control flow. This
eliminated the need for an endless loop in these places.

monitor interfaces ("mac80211: reduce the amount of unnecessary traffic
on cooked monitor interfaces ") ended up removing quite a bit more
than just unnecessary traffic. It was not supposed to remove TX status
reporting for injected frames, but ended up doing it by checking the
injected flag in skb->cb only after that field had been cleared with
memset.. Fix this by taking a local copy of the injected flag before
skb->cb is cleared.
This broke user space applications that depend on getting TX status
notifications for injected data frames. For example, STA inactivity
poll from hostapd did not work and ended up kicking out stations even
if they were still present.

b43legacy: avoid PPC fault during resume
For PPC architecture with PHY Revision < 3, a read of the register

After TCP RCU conversion, tw->tw_refcnt should not be set to 1 in

Only choice we have is to set tw_refcnt to 0 in inet_twsk_alloc(),

Its currently possible that several threads issuing a connect() find

To fix this problem, we could unhash timewait socket while holding

net: fib_rules: allow to delete local rule
Allow to delete the local rule and recreate it with a higher priority. This
can be used to force packets with a local destination out on the wire instead
of routing them to loopback. Additionally this patch allows to recreate rules
with a priority of 0.
Combined with the previous patch to allow oif classification, a socket can
be bound to the desired interface and packets routed to the wire like this:
# move local rule to lower priority
ip rule add pref 1000 lookup local
ip rule del pref 0
# route packets of sockets bound to eth0 to the wire independant
# of the destination address
ip rule add pref 100 oif eth0 lookup 100
ip route add default dev eth0 table 100

net: fib_rules: add oif classification
Support routing table lookup based on the flow's oif. This is useful to
classify packets originating from sockets bound to interfaces differently.
The route cache already includes the oif and needs no changes.

net: fib_rules: rearrange struct fib_rule
The ifname member is only used to resolve interface names and is not needed
during rule lookups. The target and ctarget members however are used during
rule lookups and are currently located in a second cacheline.
Move ifname further to the end to make sure both target and ctarget are
located in the same cacheline as other members used during rule lookups.
The layout on 64 bit changes from:
struct fib_rule {
...
u32 table; /* 56 4 */
u8 action; /* 60 1 */
/* XXX 3 bytes hole, try to pack */
/* --- cacheline 1 boundary (64 bytes) --- */
u32 target; /* 64 4 */
/* XXX 4 bytes hole, try to pack */
struct fib_rule * ctarget; /* 72 8 */
struct rcu_head rcu; /* 80 16 */
struct net * fr_net; /* 96 8 */
};
to:
struct fib_rule {
...
u32 table; /* 40 4 */
u8 action; /* 44 1 */
/* XXX 3 bytes hole, try to pack */
u32 target; /* 48 4 */

Bluetooth: Fix 'SendRRorRNR' to send the ReqSeq value
SendRRorRNR needs to acknowledge received I-frames (actually every packet
needs to acknowledge received I-frames by sending the proper packet
sequence number), so ReqSeq is set to the next I-frame number sequence to
be pulled by the reassembly function.
SendRRorRNR tells the remote side about local busy conditions, it sends
a Receiver Ready frame if local busy is false or a Receiver Not Ready
if local busy is true.
ReqSeq is the packet's field to send the number of the acknowledged
packets.

Bluetooth: Implement RejActioned flag
RejActioned is used to prevent retransmission when a entity is on the
WAIT_F state, i.e., waiting for a frame with F-bit set due local busy
condition or a expired retransmission timer. (When these two events raise
they send a frame with the Poll bit set and enters in the WAIT_F state to
wait for a frame with the Final bit set.)
The local entity doesn't send I-frames(the data frames) until the receipt
of a frame with F-bit set. When that happens it also set RejActioned to false.
RejActioned is a mandatory feature of ERTM spec.

Bluetooth: Fix sending ReqSeq on I-frames
As specified by ERTM spec an ERTM channel can acknowledge received
I-frames(the data frames) by sending an I-frame with the proper ReqSeq
value (i.e. ReqSeq is set to BufferSeq). Until now we aren't setting the
ReqSeq value on I-frame control bits. That way we can save sending
S-frames(Supervise frames) only to acknowledge receipt of I-frames. It
is very helpful to the full-duplex channel.
ReqSeq is the packet sequence number sent in an acknowledgement frame to
acknowledge receipt of frames up to (ReqSeq - 1).
BufferSeq controls the receiver buffer, it is used to delay
acknowledgement of new frames to not cause buffer overflow. BufferSeq
value is not increased until frames are pulled by reassembly function.

Bluetooth: Fix unset of SrejActioned flag
SrejActioned is a flag that when set prevents local side to retransmit a
I-frame(the data frame) already retransmitted. The local entity can
retransmit again only when it receives a SREJ frame with the F-bit set.
SREJ frame - Selective Reject frame - is sent when an entity wants the
retransmission of a specific I-frame that was lost or corrupted.
This bug can put ERTM in an unknown state once the entity can't
retransmit.
A frame with the Final bit set is expected when the local side sends a
frame with the Poll bit set due to a local busy condition or a
retransmission timer expired. (Receipt of P-bit shall always be replied by
a frame with the F-bit set).
pi->conn_state keeps informations about many ERTM flags including
SrejActioned.
