Pavel Emelyanov 5d8c0aa943 [INET]: Fix accidentally broken inet(6)_hash_connect's port offset calculations.
The port offset calculations depend on the protocol family, but, as
Adrian noticed, I broke this logic with the commit

	5ee31fc1ec
	[INET]: Consolidate inet(6)_hash_connect.

Return this logic back, by passing the port offset directly into the
consolidated function.

Dave Young eff001e35a bluetooth: hidp_process_hid_control remove unnecessary parameter dealing
According to the bluetooth HID spec v1.0 chapter 7.4.2

"This code requests a major state change in a BT-HID device.  A HID_CONTROL
request does not generate a HANDSHAKE response."

"A HID_CONTROL packet with a parameter of VIRTUAL_CABLE_UNPLUG is the only
HID_CONTROL packet a device can send to a host.  A host will ignore all other
packets."

So in the hidp_precess_hid_control function, we just need to deal with the
UNLUG packet.

Nathaniel Filardo a26af1e08a tun: impossible to deassert IFF_ONE_QUEUE or IFF_NO_PI
From: "Nathaniel Filardo" <nwfilardo@gmail.com>

Taken from http://bugzilla.kernel.org/show_bug.cgi?id=9806

The TUN/TAP driver only permits one-way transitions of IFF_NO_PI or
IFF_ONE_QUEUE during the lifetime of a tap/tun interface.  Note that
tun_set_iff contains

 541         if (ifr->ifr_flags & IFF_NO_PI)
 542                 tun->flags |= TUN_NO_PI;
 543 
 544         if (ifr->ifr_flags & IFF_ONE_QUEUE)
 545                 tun->flags |= TUN_ONE_QUEUE;

This is easily fixed by adding else branches which clear these bits.

Steps to reproduce:

This is easily reproduced by setting an interface persistant using tunctl then
attempting to open it as IFF_TAP or IFF_TUN, without asserting the IFF_NO_PI
flag.  The ioctl() will succeed and the ifr.flags word is not modified, but the
interface remains in IFF_NO_PI mode (as it was set by tunctl).

Wei Yongjun 7cc08b55fc [SCTP]: Fix kernel panic while received AUTH chunk with BAD shared key identifier
If SCTP-AUTH is enabled, received AUTH chunk with BAD shared key 
identifier will cause kernel panic.

Test as following:
step1: enabled /proc/sys/net/sctp/auth_enable
step 2:  connect  to SCTP server with auth capable. Association is 
established between endpoints. Then send a AUTH chunk with a bad 
shareid, SCTP server will kernel panic after received that AUTH chunk.

SCTP client                   SCTP server
  INIT         ---------->  
    (with auth capable)
               <----------    INIT-ACK
                              (with auth capable)
  COOKIE-ECHO  ---------->
               <----------    COOKIE-ACK
  AUTH         ---------->


AUTH chunk is like this:
  AUTH chunk
    Chunk type: AUTH (15)
    Chunk flags: 0x00
    Chunk length: 28
    Shared key identifier: 10
    HMAC identifier: SHA-1 (1)
    HMAC: 0000000000000000000000000000000000000000

The assignment of NULL to key can safely be removed, since key_for_each 
(which is just list_for_each_entry under the covers does an initial 
assignment to key anyway).

If the endpoint_shared_keys list is empty, or if the key_id being 
requested does not exist, the function as it currently stands returns 
the actuall list_head (in this case endpoint_shared_keys.  Since that 
list_head isn't surrounded by an actuall data structure, the last 
iteration through list_for_each_entry will do a container_of on key, and 
we wind up returning a bogus pointer, instead of NULL, as we should.

Wei Yongjun d2f19fa13e [SCTP]: Fix kernel panic while received AUTH chunk while enabled auth
If STCP is started while /proc/sys/net/sctp/auth_enable is set 0 and
association is established between endpoints. Then if
/proc/sys/net/sctp/auth_enable is set 1, a received AUTH chunk will
cause kernel panic.

Test as following:
step 1: echo 0> /proc/sys/net/sctp/auth_enable
step 2:

   SCTP client                  SCTP server

      COOKIE-ECHO   --------->
                    <---------   COOKIE-ACK
step 3:
    echo 1> /proc/sys/net/sctp/auth_enable
step 4:
   SCTP client                  SCTP server
       AUTH        ----------->  Kernel Panic

Rami Rosen 0aead54347 [NET_SCHED]: Add #ifdef CONFIG_NET_EMATCH in net/sched/cls_flow.c (latest git broken build)
The 2.6 latest git build was broken when using the following
configuration options:
CONFIG_NET_EMATCH=n
CONFIG_NET_CLS_FLOW=y

with the following error:
net/sched/cls_flow.c: In function 'flow_dump':
net/sched/cls_flow.c:598: error: 'struct tcf_ematch_tree' has no
member named 'hdr'
make[2]: *** [net/sched/cls_flow.o] Error 1
make[1]: *** [net/sched] Error 2
make: *** [net] Error 2


see the recent post by Li Zefan:
  http://www.spinics.net/lists/netdev/msg54434.html

The reason for this crash is that struct tcf_ematch_tree
(net/pkt_cls.h) is empty when CONFIG_NET_EMATCH is not defined.

When CONFIG_NET_EMATCH is defined, the tcf_ematch_tree structure
indeed holds a struct tcf_ematch_tree_hdr (hdr) as flow_dump()
expects.

This patch adds #ifdef CONFIG_NET_EMATCH in flow_dump to avoid this.

Christoph Lameter 7c2e132c54 Add parameter to add_partial to avoid having two functions
Add a parameter to add_partial instead of having separate functions.  The
parameter allows a more detailed control of where the slab pages is placed in
the partial queues.

If we put slabs back to the front then they are likely immediately used for
allocations.  If they are put at the end then we can maximize the time that
the partial slabs spent without being subject to allocations.

When deactivating slab we can put the slabs that had remote objects freed (we
can see that because objects were put on the freelist that requires locks) to
them at the end of the list so that the cachelines of remote processors can
cool down.  Slabs that had objects from the local cpu freed to them (objects
exist in the lockless freelist) are put in the front of the list to be reused
ASAP in order to exploit the cache hot state of the local cpu.

Patch seems to slightly improve tbench speed (1-2%).

Catalin Marinas 41579f49da [ARM] 4822/1: RealView: Change the REALVIEW_MPCORE configuration option
This patch changes the REALVIEW_MPCORE configuration option to
REALVIEW_EB_ARM11MP since this is only specific to RealView/EB.

Catalin Marinas 39e823e35b [ARM] 4821/1: RealView: Remove the platform dependencies from localtimer.c
This patch removes the TWD_BASE macro used to set up and configure the
local timers on ARM11MPCore. The twd_base_addr and twd_size variables
are defined in localtimer.c and set from the realview_eb_init function.

Catalin Marinas 8cc4c5488a [ARM] 4820/1: RealView: Select the timer IRQ at run-time
This patch sets the timer IRQ at run-time by moving the sys_timer
structure and the timer_init function to the realview_eb.c file. This
allows multiple RealView platforms to be compiled in the same kernel
image.

Catalin Marinas c4057f5260 [ARM] 4819/1: RealView: Fix entry-macro.S to work with multiple platforms
This patch modifies the get_irqnr_preamble macro to work with multiple
platforms at run-time by reading the address of the GIC controller from
the gic_cpu_base_addr variable. This variable is defined in core.c and
intialised in realview_eb.c (gic_init_irq).

Catalin Marinas 7dd19e755d [ARM] 4818/1: RealView: Add core-tile detection
This patch adds the core-tile detection and only enables devices if the
corresponding tile is present. It currently detects the ARM11MPCore via
the core_tile_eb11mp() macro.

Catalin Marinas 0fc2a1616f [ARM] 4817/1: RealView: Move the AMBA resource definitions to realview_eb.c
This patch moves the IRQ and DMA definitions from core.h into
realview_eb.c since they are platform-specific. It adds a
realview_eb11mp_fixup function to adjust the IRQ numbers if the
ARM11MPCore tile is fitted. The realview_smc91x_device is also moved
from core.c into realview_eb.c.

Catalin Marinas 356cb470b8 [ARM] 4816/1: RealView: Move the platform-specific definitions into board-eb.h
This patch moves the platform specific definitions from platform.h into
the board-eb.h file. It drops the INT_* definitions as they are no
longer used in irqs.h (moved to board-eb.h). It renames REALVIEW_*
macros to REALVIEW_EB_* or REALVIEW_EB11MP_* to distinguish between
standard EB and EB + the ARM11MPCore tile. The platform.h file contains
common definitions to the RealView platforms and it is only directly
included in board-*.h files.

Catalin Marinas 93c2904d50 [ARM] 4815/1: RealView: Add clockevents suport for the local timers

Catalin Marinas a8655e83fc [ARM] 4814/1: RealView: Add broadcasting clockevents support for ARM11MPCore
This patch adds dummy local timers for each CPU so that the board clock
device is used to broadcast events to the other CPUs. The patch also
adds the declaration for the dummy_timer_setup function (the equivalent
of local_timer_setup when CONFIG_LOCAL_TIMERS is not set).

Due to the way clockevents work, the dummy timer on the first CPU has to
be registered before the board timer.
