rtlwifi: rtl_usb: Fix missing entry in USB driver's private data

2017-01-15T12:42:58+00:00

commit 60f59ce0278557f7896d5158ae6d12a4855a72cc upstream.

These drivers need to be able to reference "struct ieee80211_hw" from
the driver's private data, and vice versa. The USB driver failed to
store the address of ieee80211_hw in the private data. Although this
bug has been present for a long time, it was not exposed until
commit ba9f93f82aba ("rtlwifi: Fix enter/exit power_save").

rtlwifi: Fix enter/exit power_save

2017-01-15T12:42:57+00:00

commit ba9f93f82abafe2552eac942ebb11c2df4f8dd7f upstream.

In commit a5ffbe0a1993 ("rtlwifi: Fix scheduling while atomic bug") and
commit a269913c52ad ("rtlwifi: Rework rtl_lps_leave() and rtl_lps_enter()
to use work queue"), an error was introduced in the power-save routines
due to the fact that leaving PS was delayed by the use of a work queue.

This problem is fixed by detecting if the enter or leave routines are
in interrupt mode. If so, the workqueue is used to place the request.
If in normal mode, the enter or leave routines are called directly.

net: vrf: do not allow table id 0

2017-01-15T12:42:56+00:00

[ Upstream commit 24c63bbc18e25d5d8439422aa5fd2d66390b88eb ]

Frank reported that vrf devices can be created with a table id of 0.
This breaks many of the run time table id checks and should not be
allowed. Detect this condition at create time and fail with EINVAL.

net: ipv4: Fix multipath selection with vrf

2017-01-15T12:42:55+00:00

[ Upstream commit 7a18c5b9fb31a999afc62b0e60978aa896fc89e9 ]

fib_select_path does not call fib_select_multipath if oif is set in the
flow struct. For VRF use cases oif is always set, so multipath route
selection is bypassed. Use the FLOWI_FLAG_SKIP_NH_OIF to skip the oif
check similar to what is done in fib_table_lookup.

Add saddr and proto to the flow struct for the fib lookup done by the
VRF driver to better match hash computation for a flow.

net/mlx5e: Remove WARN_ONCE from adaptive moderation code

2017-01-15T12:42:55+00:00

[ Upstream commit 0bbcc0a8fc394d01988fe0263ccf7fddb77a12c3 ]

When trying to do interface down or changing interface configuration
under heavy traffic, some of the adaptive moderation corner cases can
occur and leave a WARN_ONCE call trace in the kernel log.

Those WARN_ONCE are meant for debug only, and should have been inserted
only under debug. We avoid such call traces by removing those WARN_ONCE.

r8152: fix rx issue for runtime suspend

2017-01-15T12:42:55+00:00

[ Upstream commit 75dc692eda114cb234a46cb11893a9c3ea520934 ]

Pause the rx and make sure the rx fifo is empty when the autosuspend
occurs.

If the rx data comes when the driver is canceling the rx urb, the host
controller would stop getting the data from the device and continue
it after next rx urb is submitted. That is, one continuing data is
split into two different urb buffers. That let the driver take the
data as a rx descriptor, and unexpected behavior happens.

net: dsa: bcm_sf2: Do not clobber b53_switch_ops

[ Upstream commit a4c61b92b3a4cbda35bb0251a5063a68f0861b2c ]

We make the bcm_sf2 driver override ds->ops which points to
b53_switch_ops since b53_switch_alloc() did the assignent. This is all
well and good until a second b53 switch comes in, and ends up using the
bcm_sf2 operations. Make a proper local copy, substitute the ds->ops
pointer and then override the operations.
