wireless: cw1200: acquire hwbus lock around cw1200_irq_handler() call.

2013-11-04T12:35:21+00:00

commit 4978705d26149a629b9f50ff221caed6f1ae3048 upstream.

This fixes "lost interrupt" problems that occurred on SPI-based systems.
cw1200_irq_handler() expects the hwbus to be locked, but on the
SPI-path, that lock wasn't taken (unlike in the SDIO-path, where the
generic SDIO-code takes care of acquiring the lock).

davinci_emac.c: Fix IFF_ALLMULTI setup

2013-11-04T12:35:18+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.

be2net: pass if_id for v1 and V2 versions of TX_CREATE cmd

2013-11-04T12:35:17+00:00

[ Upstream commit 0fb88d61bc60779dde88b0fc268da17eb81d0412 ]

It is a required field for all TX_CREATE cmd versions > 0.
This fixes a driver initialization failure, caused by recent SH-R Firmwares
(versions > 10.0.639.0) failing the TX_CREATE cmd when if_id field is
not passed.

wanxl: fix info leak in ioctl

2013-11-04T12:35:17+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.

virtio-net: refill only when device is up during setting queues

2013-11-04T12:35:16+00:00

[ Upstream commit 35ed159bfd96a7547ec277ed8b550c7cbd9841b6 ]

We used to schedule the refill work unconditionally after changing the
number of queues. This may lead an issue if the device is not
up. Since we only try to cancel the work in ndo_stop(), this may cause
the refill work still work after removing the device. Fix this by only
schedule the work when device is up.

The bug were introduce by commit 9b9cd8024a2882e896c65222aa421d461354e3f2.

virtio-net: don't respond to cpu hotplug notifier if we're not ready

2013-11-04T12:35:16+00:00

[ Upstream commit 3ab098df35f8b98b6553edc2e40234af512ba877 ]

We're trying to re-configure the affinity unconditionally in cpu hotplug
callback. This may lead the issue during resuming from s3/s4 since

- virt queues haven't been allocated at that time.
- it's unnecessary since thaw method will re-configure the affinity.

Fix this issue by checking the config_enable and do nothing is we're not ready.

The bug were introduced by commit 8de4b2f3ae90c8fc0f17eeaab87d5a951b66ee17
(virtio-net: reset virtqueue affinity when doing cpu hotplug).

bnx2x: record rx queue for LRO packets

2013-11-04T12:35:16+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/mlx4_en: Fix pages never dma unmapped on rx

2013-11-04T12:35:14+00:00

[ Upstream commit 021f1107ffdae7a82af6c53f4c52654062e365c6 ]

This patch fixes a bug introduced by commit 51151a16 (mlx4: allow
order-0 memory allocations in RX path).

dma_unmap_page never reached because condition to detect last fragment
in page is wrong. offset+frag_stride can't be greater than size, need to
make sure no additional frag will fit in page => compare offset +
frag_stride + next_frag_size instead.
next_frag_size is the same as the current one, since page is shared only
with frags of the same size.
