wl18xx: show rx_frames_per_rates as an array as it really is

2015-05-06T20:02:04+00:00

commit a3fa71c40f1853d0c27e8f5bc01a722a705d9682 upstream.

In struct wl18xx_acx_rx_rate_stat, rx_frames_per_rates field is an
array, not a number.  This means WL18XX_DEBUGFS_FWSTATS_FILE can't be
used to display this field in debugfs (it would display a pointer, not
the actual data).  Use WL18XX_DEBUGFS_FWSTATS_FILE_ARRAY instead.

This bug has been found by adding a __printf attribute to
wl1271_format_buffer.  gcc complained about "format '%u' expects
argument of type 'unsigned int', but argument 5 has type 'u32 *'".

rtlwifi: rtl8192ee: Fix handling of new style descriptors

2015-04-29T08:23:47+00:00

commit d0311314d00298f83aa5450a1d4a92889e7cc2ea upstream.

The hardware and firmware for the RTL8192EE utilize a FIFO list of
descriptors. There were some problems with the initial implementation.
The worst of these failed to detect that the FIFO was becoming full,
which led to the device needing to be power cycled. As this condition
is not relevant to most of the devices supported by rtlwifi, a callback
routine was added to detect this situation. This patch implements the
necessary changes in the pci handler, and the linkage into the appropriate
rtl8192ee routine.

rtlwifi: Fix IOMMU mapping leak in AP mode

2015-04-19T08:10:23+00:00

commit be0b5e635883678bfbc695889772fed545f3427d upstream.

Transmission of an AP beacon does not call the TX interrupt service routine,
which usually does the cleanup. Instead, cleanup is handled in a tasklet
completion routine. Unfortunately, this routine has a serious bug in that it does
not release the DMA mapping before it frees the skb, thus one IOMMU mapping is
leaked for each beacon. The test system failed with no free IOMMU mapping slots
approximately one hour after hostapd was used to start an AP.

This issue was reported and tested at https://github.com/lwfinger/rtlwifi_new/issues/30.

brcmfmac: disable MBSS feature for BCM43362

2015-04-19T08:10:23+00:00

commit f93a25b38cbd840f26c9fd2dd8a6611a57b259b7 upstream.

The BCM43362 firmware falsely reports it is capable of providing
MBSS. As a result AP mode no longer works for this device. Therefor
disable MBSS in the driver for this chipset.

ath9k: fix tracking of enabled AP beacons

2015-04-19T08:10:20+00:00

commit 1cf48f22c98ae24a49a3f1b6900e4c9a9a0fcc62 upstream.

sc->nbcnvifs tracks assigned beacon slots, not enabled beacons.
Therefore, it cannot be used to decide if cur_conf->enable_beacon (bool)
should be updated, or if beacons have been enabled already.
With the current code (depending on the order of calls), beacons often
do not get enabled in an AP+STA setup.
To fix tracking of enabled beacons, convert cur_conf->enable_beacon to a
bitmask of enabled beacon slots.

iwlwifi: dvm: run INIT firmware again upon .start()

2015-04-19T08:10:16+00:00

commit 9c8928f5176766bec79f272bd47b7124e11cccbd upstream.

The assumption before this patch was that we don't need to
run again the INIT firmware after the system booted. The
INIT firmware runs calibrations which impact the physical
layer's behavior.
Users reported that it may be helpful to run these
calibrations again every time the interface is brought up.
The penatly is minimal, since the calibrations run fast.

rtlwifi: Improve handling of IPv6 packets

2015-04-13T12:03:53+00:00

commit c8f0345586694a33f828bc6b177fb21eb1702325 upstream.

Routine rtl_is_special_data() is supposed to identify packets that need to
use a low bit rate so that the probability of successful transmission is
high. The current version has a bug that causes all IPv6 packets to be
labelled as special, with a corresponding low rate of transmission. A
complete fix will be quite intrusive, but until that is available, all
IPv6 packets are identified as regular.

This patch also removes a magic number.
