Eric Van Hensbergen 8a0dc95fd9 9p: transport API reorganization
This merges the mux.c (including the connection interface) with trans_fd
in preparation for transport API changes.  Ultimately, trans_fd will need
to be rewritten to clean it up and simplify the implementation, but this
reorganization is viewed as the first step.

Eric Van Hensbergen f39335453f 9p: add remove function to trans_virtio
Request from rusty:
Just cleaning up patches for 2.6.25 merge, and noticed that
net/9p/trans_virtio.c doesn't have a remove function.  This will crash when
removing the module (console doesn't have one because it can't really be
removed).

Anthony Liguori dea7bbb603 9p: Convert semaphore to spinlock for p9_idpool
When booting from v9fs, down_interruptible in p9_idpool_get() triggered a BUG
as it was being called with IRQs disabled.  A spinlock seems like the right
thing to be using since the idr functions go out of their way not to sleep.

This patch eliminates the BUG by converting the semaphore to a spinlock.

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.

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


This patch fix this probleam to treat AUTH chunk as unknow chunk if peer 
has initialized with no auth capable.
