      net/mlx4_core: Fix slave id computation for single port VF · 0254bc82
      Matan Barak authored 
      The code that deals with computing the slave id based on a given GID
gave wrong results when the number of single port VFs wasn't the
same for port 1 vs. port 2 and the relevant VF is single ported on
port 2. As a result, incoming CM MADs were dispatched to the wrong VF.
Fixed that and added documentation to clarify the computation steps.

      net/mlx4_core: Adjust port number in qp_attach wrapper when detaching · 531d9014
      Jack Morgenstein authored 
      When using single ported VFs and the VF is using port 2, we need
to adjust the port accordingly (change it from 1 to 2).

      net: cdc_ncm: fix buffer overflow · 9becd707
      Bjørn Mork authored 
      Commit 4d619f62 ("net: cdc_ncm: no point in filling up the NTBs
if we send ZLPs") changed the padding logic for devices with the ZLP
flag set.  This meant that frames of any size will be sent without
additional padding, except for the single byte added if the size is
a multiple of the USB packet size. But if the unpadded size is
identical to the maximum frame size, and the maximum size is a
multiplum of the USB packet size, then this one-byte padding will
overflow the buffer.

Prevent padding if already at maximum frame size, letting usbnet
transmit a ZLP instead in this case.

Fixes: 4d619f62 ("net: cdc_ncm: no point in filling up the NTBs if we send ZLPs")

      vsock: Make transport the proto owner · 2c4a336e
      Andy King authored 
      Right now the core vsock module is the owner of the proto family. This
means there's nothing preventing the transport module from unloading if
there are open sockets, which results in a panic. Fix that by allowing
the transport to be the owner, which will refcount it properly.

Includes version bump to 1.0.1.0-k

Passes checkpatch this time, I swear...

      John W. Linville says:

====================
pull request: wireless 2014-05-01

Please pull the following batch of fixes intended for the 3.15 stream!

For the Bluetooth bits, Gustavo says:

"Some fixes for 3.15. There is a revert for the intel driver, a new
device id, and two important SSP fixes from Johan."

On top of that...

Ben Hutchings gives us a fix for an unbalanced irq enable in an
rtl8192cu error path.

Colin Ian King provides an rtlwifi fix for an uninitialized variable.

Felix Fietkau brings a pair of ath9k fixes, one that corrects a
hardware initialization value and another that removes an (unnecessary)
flag that was being used in a way that led to a software tx queue
hang in ath9k.

Gertjan van Wingerde pushes a MAINTAINERS change to remove himself
from the rt2x00 maintainer team.

Hans de Goede fixes a brcmfmac firmware load hang.

Larry Finger changes rtlwifi to use the correct queue for V0 traffic
on rtl8192se.

Rajkumar Manoharan corrects a race in ath9k driver initialization.

Stanislaw Gruszka fixes an rt2x00 bug in which disabling beaconing
once on USB devices led to permanently disabling beaconing for those
devices.

Tim Harvey provides fixes for a pair of ath9k issues that can lead
to soft lockups in that driver.

Please let me know if there are problems!

      sctp: reset flowi4_oif parameter on route lookup · 85350871
      Xufeng Zhang authored 
      commit 813b3b5d (ipv4: Use caller's on-stack flowi as-is
in output route lookups.) introduces another regression which
is very similar to the problem of commit e6b45241 (ipv4: reset
flowi parameters on route connect) wants to fix:
Before we call ip_route_output_key() in sctp_v4_get_dst() to
get a dst that matches a bind address as the source address,
we have already called this function previously and the flowi
parameters have been initialized including flowi4_oif, so when
we call this function again, the process in __ip_route_output_key()
will be different because of the setting of flowi4_oif, and we'll
get a networking device which corresponds to the inputted flowi4_oif
as the output device, this is wrong because we'll never hit this
place if the previously returned source address of dst match one
of the bound addresses.

To reproduce this problem, a vlan setting is enough:
  # ifconfig eth0 up
  # route del default
  # vconfig add eth0 2
  # vconfig add eth0 3
  # ifconfig eth0.2 10.0.1.14 netmask 255.255.255.0
  # route add default gw 10.0.1.254 dev eth0.2
  # ifconfig eth0.3 10.0.0.14 netmask 255.255.255.0
  # ip rule add from 10.0.0.14 table 4
  # ip route add table 4 default via 10.0.0.254 src 10.0.0.14 dev eth0.3
  # sctp_darn -H 10.0.0.14 -P 36422 -h 10.1.4.134 -p 36422 -s -I
You'll detect that all the flow are routed to eth0.2(10.0.1.254).
