      ipv4: Rearrange how ip_route_newports() gets port keys. · dca8b089
      由 David S. Miller 提交于 
      ip_route_newports() is the only place in the entire kernel that
cares about the port members in the routing cache entry's lookup
flow key.

Therefore the only reason we store an entire flow inside of the
struct rtentry is for this one special case.

Rewrite ip_route_newports() such that:

1) The caller passes in the original port values, so we don't need
   to use the rth->fl.fl_ip_{s,d}port values to remember them.

2) The lookup flow is constructed by hand instead of being copied
   from the routing cache entry's flow.

      netfilter: tproxy: do not assign timewait sockets to skb->sk · d503b30b
      由 Florian Westphal 提交于 
      Assigning a socket in timewait state to skb->sk can trigger
kernel oops, e.g. in nfnetlink_log, which does:

if (skb->sk) {
        read_lock_bh(&skb->sk->sk_callback_lock);
        if (skb->sk->sk_socket && skb->sk->sk_socket->file) ...

in the timewait case, accessing sk->sk_callback_lock and sk->sk_socket
is invalid.

Either all of these spots will need to add a test for sk->sk_state != TCP_TIME_WAIT,
or xt_TPROXY must not assign a timewait socket to skb->sk.

This does the latter.

If a TW socket is found, assign the tproxy nfmark, but skip the skb->sk assignment,
thus mimicking behaviour of a '-m socket .. -j MARK/ACCEPT' re-routing rule.

The 'SYN to TW socket' case is left unchanged -- we try to redirect to the
listener socket.

      Bluetooth: Send LE Connection Update Command · 2ce603eb
      由 Claudio Takahasi 提交于 
      If the new connection update parameter are accepted, the LE master
host sends the LE Connection Update Command to its controller informing
the new requested parameters.

      Bluetooth: Use proper timer for hci command timout · 6bd32326
      由 Ville Tervo 提交于 
      Use proper timer instead of hci command flow control to timeout
failed hci commands. Otherwise stack ends up sending commands
when flow control is used to block new commands.

      Bluetooth: Add connection parameter update response · de73115a
      由 Claudio Takahasi 提交于 
      Implements L2CAP Connection Parameter Update Response defined in
the Bluetooth Core Specification, Volume 3, Part A, section 4.21.
Address the LE Connection Parameter Procedure initiated by the slave.

Connection Interval Minimum and Maximum have the same range: 6 to
3200. Time = N * 1.25ms. Minimum shall be less or equal to Maximum.
The Slave Latency field shall have a value in the range of 0 to
((connSupervisionTimeout / connIntervalMax) - 1). Latency field shall
be less than 500. connSupervisionTimeout = Timeout Multiplier * 10 ms.
Multiplier field shall have a value in the range of 10 to 3200.

      Bluetooth: Add LE signaling commands handling · 3300d9a9
      由 Claudio Takahasi 提交于 
      This patch splits the L2CAP command handling function in order to
have a clear separation between the commands related to BR/EDR and
LE. Commands and responses in the LE signaling channel are not being
handled yet, command reject is sent to all received requests. Bluetooth
Core Specification, Volume 3, Part A, section 4 defines the signaling
packets formats and allowed commands/responses over the LE signaling
channel.
