davinci_emac.c: Fix IFF_ALLMULTI setup

2013-11-04T12:23:41+00:00

[ Upstream commit d69e0f7ea95fef8059251325a79c004bac01f018 ]

When IFF_ALLMULTI flag is set on interface and IFF_PROMISC isn't,
emac_dev_mcast_set should only enable RX of multicasts and reset
MACHASH registers.

It does this, but afterwards it either sets up multicast MACs
filtering or disables RX of multicasts and resets MACHASH registers
again, rendering IFF_ALLMULTI flag useless.

This patch fixes emac_dev_mcast_set, so that multicast MACs filtering and
disabling of RX of multicasts are skipped when IFF_ALLMULTI flag is set.

Tested with kernel 2.6.37.

wanxl: fix info leak in ioctl

2013-11-04T12:23:41+00:00

[ Upstream commit 2b13d06c9584b4eb773f1e80bbaedab9a1c344e1 ]

The wanxl_ioctl() code fails to initialize the two padding bytes of
struct sync_serial_settings after the ->loopback member. Add an explicit
memset(0) before filling the structure to avoid the info leak.

bnx2x: record rx queue for LRO packets

2013-11-04T12:23:41+00:00

[ Upstream commit 60e66fee56b2256dcb1dc2ea1b2ddcb6e273857d ]

RPS support is kind of broken on bnx2x, because only non LRO packets
get proper rx queue information. This triggers reorders, as it seems
bnx2x like to generate a non LRO packet for segment including TCP PUSH
flag : (this might be pure coincidence, but all the reorders I've
seen involve segments with a PUSH)

We must call skb_record_rx_queue() to properly give to RPS (and more
generally for TX queue selection on forward path) the receive queue
information.

Similar fix is needed for skb_mark_napi_id(), but will be handled
in a separate patch to ease stable backports.

net: mv643xx_eth: fix orphaned statistics timer crash

2013-11-04T12:23:40+00:00

[ Upstream commit f564412c935111c583b787bcc18157377b208e2e ]

The periodic statistics timer gets started at port _probe() time, but
is stopped on _stop() only. In a modular environment, this can cause
the timer to access already deallocated memory, if the module is unloaded
without starting the eth device. To fix this, we add the timer right
before the port is started, instead of at _probe() time.

[ Upstream commit 041b4ddb84989f06ff1df0ca869b950f1ee3cb1c ]

Each port driver installs a periodic timer to update port statistics
by calling mib_counters_update. As mib_counters_update is also called
from non-timer context, we should not reschedule the timer there but
rather move it to timer-only context.

rtlwifi: Align private space in rtl_priv struct

commit 60ce314d1750fef843e9db70050e09e49f838b69 upstream.

The private array at the end of the rtl_priv struct is not aligned.
On ARM architecture, this causes an alignment trap and is fixed by aligning
that array with __align(sizeof(void *)). That should properly align that
space according to the requirements of all architectures.

ll_temac: Reset dma descriptors indexes on ndo_open

2013-10-13T22:42:48+00:00

[ Upstream commit 7167cf0e8cd10287b7912b9ffcccd9616f382922 ]

The dma descriptors indexes are only initialized on the probe function.

If a packet is on the buffer when temac_stop is called, the dma
descriptors indexes can be left on a incorrect state where no other
package can be sent.

So an interface could be left in an usable state after ifdow/ifup.

This patch makes sure that the descriptors indexes are in a proper
status when the device is open.
