pppoe: drop PPPOX_ZOMBIEs in pppoe_release

2012-10-12T20:47:03+00:00

[ Upstream commit 2b018d57ff18e5405823e5cb59651a5b4d946d7b ]

When PPPOE is running over a virtual ethernet interface (e.g., a
bonding interface) and the user tries to delete the interface in case
the PPPOE state is ZOMBIE, the kernel will loop forever while
unregistering net_device for the reference count is not decreased to
zero which should have been done with dev_put().

sierra_net: Endianess bug fix.

2012-10-12T20:47:01+00:00

[ Upstream commit 2120c52da6fe741454a60644018ad2a6abd957ac ]

I discovered I couldn't get sierra_net to work on a powerpc.  Turns out
the firmware attribute check assumes the system is little endian and
hence fails because the attributes is a 16 bit value.

netxen: check for root bus in netxen_mask_aer_correctable

2012-10-12T20:47:00+00:00

[ Upstream commit e4d1aa40e363ed3e0486aeeeb0d173f7f822737e ]

Add a check if pdev->bus->self == NULL (root bus). When attaching
a netxen NIC to a VM it can be on the root bus and the guest would
crash in netxen_mask_aer_correctable() because of a NULL pointer
dereference if CONFIG_PCIEAER is present.

ixp4xx_hss: fix build failure due to missing linux/module.h inclusion

2012-10-12T20:47:00+00:00

[ Upstream commit 0b836ddde177bdd5790ade83772860940bd481ea ]

Commit 36a1211970193ce215de50ed1e4e1272bc814df1 (netprio_cgroup.h:
dont include module.h from other includes) made the following build
error on ixp4xx_hss pop up:

This was previously hidden because ixp4xx_hss includes linux/hdlc.h which
includes linux/netdevice.h which includes linux/netprio_cgroup.h which
used to include linux/module.h. The real issue was actually present since
the initial commit that added this driver since it uses macros from
linux/module.h without including this file.

net: ethernet: davinci_cpdma: decrease the desc count when cleaning up the remaining packets

2012-10-12T20:47:00+00:00

[ Upstream commit ffb5ba90017505a19e238e986e6d33f09e4df765 ]

chan->count is used by rx channel. If the desc count is not updated by
the clean up loop in cpdma_chan_stop, the value written to the rxfree
register in cpdma_chan_start will be incorrect.

bnx2x: fix rx checksum validation for IPv6

2012-10-12T20:46:57+00:00

[ Upstream commit e488921f44765e8ab6c48ca35e3f6b78df9819df ]

Commit d6cb3e41 "bnx2x: fix checksum validation" caused a performance
regression for IPv6. Rx checksum offload does not work. IPv6 packets
are passed to the stack with CHECKSUM_NONE.

The hardware obviously cannot perform IP checksum validation for IPv6,
because there is no checksum in the IPv6 header. This should not prevent
us from setting CHECKSUM_UNNECESSARY.

Tested on BCM57711.

rapidio/rionet: fix multicast packet transmit logic

2012-10-12T20:46:56+00:00

commit 7c4a6106d6451fc03c491e61df37c044505d843a upstream.

Fix multicast packet transmit logic to account for repetitive transmission
of single skb:
- correct check for available buffers (this bug may produce NULL pointer
  crash dump in case of heavy traffic);
- update skb user count (incorrect user counter causes a warning dump from
  net_tx_action routine during multicast transfers in systems with three or
  more rionet participants).

ixgbe: fix PTP ethtool timestamping function

commit 1cc92eb871d6cbb1da038b4bcd89eec3c73b9781 upstream.

This patch fixes a development issue that occurred due to invalid modes reported
in the ethtool get_ts_info function. The issue is resolved by removing
unsupported modes from the Rx supported list.

can: mscan-mpc5xxx: fix return value check in mpc512x_can_get_clock()

2012-10-07T15:35:56+00:00

commit f61bd0585dfc7d99db4936d7467de4ca8e2f7ea0 upstream.

In case of error, the function clk_get() returns ERR_PTR()
and never returns NULL pointer. The NULL test in the error
handling should be replaced with IS_ERR().

ath9k: Disable ASPM only for AR9285

2012-10-07T15:35:54+00:00

commit 046b6802c8d3c8a57448485513bf7291633e0fa3 upstream.

Currently, ASPM is disabled for all WLAN+BT combo chipsets
when BTCOEX is enabled. This is incorrect since the workaround
is required only for WB195, which is a AR9285+AR3011 combo
solution. Fix this by checking for the HW version when enabling
the workaround.
