b43: Fix firmware loading when driver is built into the kernel · 5e20a4b5

由 Larry Finger 提交于 12月 20, 2012

Recent versions of udev cause synchronous firmware loading from the
probe routine to fail because the request to user space would time
out. The original fix for b43 (commit 6b6fa586) moved the firmware
load from the probe routine to a work queue, but it still used synchronous
firmware loading. This method is OK when b43 is built as a module;
however, it fails when the driver is compiled into the kernel.

This version changes the code to load the initial firmware file
using request_firmware_nowait(). A completion event is used to
hold the work queue until that file is available. This driver
reads several firmware files - the remainder can be read synchronously.
On some test systems, the async read fails; however, a following synch
read works, thus the async failure falls through to the sync try.

wireless: add new wil6210 802.11ad 60GHz driver · 2be7d22f

由 Vladimir Kondratiev 提交于 12月 20, 2012

This adds support for the 60 GHz 802.11ad Wilocity card
through a new driver, wil6210. Wilocity implemented the
firmware, QCA maintains the device driver.

Currently supported:

- STA: with security
- AP: limited to 1 connected STA, security disabled
- Monitor: due to a hardware/firmware limitation
  either control or non-control frames are monitored

Using a STA and AP with this drive, one can assemble
a fully functional BSS. Throughput of 1.2Gbps is achieved
with iperf.

The wil6210 cards have on-board flash memory for the
firmware, the cards comes pre-flashed and no firmware
download is required.

mwifiex: check wait_event_interruptible return value · 9c969d8c

由 Bing Zhao 提交于 1月 02, 2013

wait_event_interruptible function returns -ERESTARTSYS if it's
interrupted by a signal. Driver should check the return value
and handle this case properly.

In mwifiex_wait_queue_complete() routine, as we are now checking
wait_event_interruptible return value, the condition check is not
required. Also, we have removed mwifiex_cancel_pending_ioctl()
call to avoid a chance of sending second command to FW by other path
as soon as we clear current command node. FW can not handle two
commands simultaneously.

ath9k: Fix Kconfig for ATH9K_HTC · 9a6f7347

由 Vladimir Kondratiev 提交于 1月 03, 2013

Ath9k consists of 2 different sub-modules: ATH9K and ATH9K_HTC.
Both uses common Atheros code from ath.ko and need ATH_COMMON.

However, while ATH9K selects ATH_COMMON, ATH9K_HTC does not.
As result, if ATH9K_HTC is the only Atheros card selected, compilation fails with
unresolved symbols.

This patch moves ATH_COMMON selection to the common part for both
ATH9K and ATH9K_HTC

mac80211: fix dtim_period in hidden SSID AP association · 826262c3

由 Johannes Berg 提交于 12月 10, 2012

When AP's SSID is hidden the BSS can appear several times in
cfg80211's BSS list: once with a zero-length SSID that comes
from the beacon, and once for each SSID from probe reponses.

Since the mac80211 stores its data in ieee80211_bss which
is embedded into cfg80211_bss, mac80211's data will be
duplicated too.

This becomes a problem when a driver needs the dtim_period
since this data exists only in the beacon's instance in
cfg80211 bss table which isn't the instance that is used
when associating.

Remove the DTIM period from the BSS table and track it
explicitly to avoid this problem.

mac80211: use del_timer_sync for final sta cleanup timer deletion · a56f992c

This is a very old bug, but there's nothing that prevents the
timer from running while the module is being removed when we

The timer should normally not be running at this point, but
it's not clearly impossible (or we could just remove this.)

mac80211: fix station destruction in AP/mesh modes · 97f97b1f

由 Johannes Berg 提交于 12月 13, 2012

Unfortunately, commit b22cfcfc, intended to speed up roaming
by avoiding the synchronize_rcu() broke AP/mesh modes as it moved
some code into that work item that will still call into the driver
at a time where it's no longer expected to handle this: after the
AP or mesh has been stopped.

To fix this problem remove the per-station work struct, maintain a
station cleanup list instead and flush this list when stations are
flushed. To keep this patch smaller for stable, do this when the
stations are flushed (sta_info_flush()). This unfortunately brings
back the original roaming delay; I'll fix that again in a separate
patch.

Also, Ben reported that the original commit could sometimes (with
many interfaces) cause long delays when an interface is set down,
due to blocking on flush_workqueue(). Since we now maintain the
cleanup list, this particular change of the original patch can be
reverted.
