git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq Pull workqueue [delayed_]work_pending() cleanups from Tejun Heo: "This is part of on-going cleanups to remove / minimize usages of workqueue interfaces which are deprecated and/or misleading. This round drops a number of usages of [delayed_]work_pending(), which are dangerous as they lack any form of synchronization and thus often lead to buggy / unnecessary code. There are a couple legitimate use cases in kernel. Hopefully, they can be converted and [delayed_]work_pending() can be removed completely. Even if not, removing most of misuses should make it more difficult to find examples of misuses and thus slow down growth of them. These changes are independent from other workqueue changes." * 'for-3.9-cleanups' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq: wimax/i2400m: fix i2400m->wake_tx_skb handling kprobes: fix wait_for_kprobe_optimizer() ipw2x00: simplify scan_event handling video/exynos: don't use [delayed_]work_pending() tty/max3100: don't use [delayed_]work_pending() x86/mce: don't use [delayed_]work_pending() rfkill: don't use [delayed_]work_pending() wl1251: don't use [delayed_]work_pending() thinkpad_acpi: don't use [delayed_]work_pending() mwifiex: don't use [delayed_]work_pending() sja1000: don't use [delayed_]work_pending()

2013-02-11mwl8k: fix band for supported channelsJonas Gorski
The band field for the supported channels were left unpopulated, making them default to 0 == IEEE80211_BAND_2GHZ, even for the 5GHz channels. This resulted in null pointer accesses if anything tries to access wiphy->bands[channel->band] of a 5GHz channel on 5GHz only cards, since wiphy->bands[2GHZ] is NULL for them (e.g. cfg80211_chandef_usable does).

2013-02-04brcmsmac: rework of mac80211 .flush() callback operationArend van Spriel
This patch addresses a long standing issue of the driver with the mac80211 .flush() callback. Since implementing the .flush() callback a number of issues have been fixed, but a WARN_ON_ONCE() was still triggered because the timeout on the flush could still occur. This patch changes the awkward design using msleep() into one using a waitqueue. The waiting flush() context will kick the transmit dma when it is idle and the timeout used waiting for the event is set to 500 ms. Worst case there can be 64 frames outstanding for transmit in the driver. At a rate of 1Mbps that would take 1.5 seconds assuming MTU is 1500 bytes and ignoring retries. The WARN_ON_ONCE() is also removed as this was put in to indicate the flush timeout as a reason for the driver to stall. That was not happening since fixing endless AMPDU retries with following upstream commit: commit 85091fc0a75653e239dc8379658515e577544927 Author: Arend van Spriel <arend@broadcom.com> Date: Thu Feb 23 18:38:22 2012 +0100 brcm80211: smac: fix endless retry of A-MPDU transmissions bugzilla: 42840 <https://bugzilla.kernel.org/show_bug.cgi?id=42840> bugzilla@redhat: <https://bugzilla.redhat.com/show_bug.cgi?id=799168> bugzilla@redhat: <https://bugzilla.redhat.com/show_bug.cgi?id=787649> Cc: Jonathan Nieder <jrnieder@gmail.com> Cc: Stanislaw Gruszka <sgruszka@redhat.com> Cc: Camaleón <noelamac@gmail.com> Cc: Milan Bouchet-Valat <nalimilan@club-internet.fr> Cc: Seth Forshee <seth.forshee@canonical.com> Reviewed-by: Pieter-Paul Giesberts <pieterpg@broadcom.com> Reviewed-by: Hante Meuleman <meuleman@broadcom.com> Reviewed-by: Piotr Haber <phaber@broadcom.com> Signed-off-by: Arend van Spriel <arend@broadcom.com> Acked-by: Seth Forshee <seth.forshee@canonical.com> Signed-off-by: John W.

2013-02-04rtlwifi: Fix scheduling while atomic bugLarry Finger
Kernel commits 41affd5 and 6539306 changed the locking in rtl_lps_leave() from a spinlock to a mutex by doing the calls indirectly from a work queue to reduce the time that interrupts were disabled. This change was fine for most systems; however a scheduling while atomic bug was reported in https://bugzilla.redhat.com/show_bug.cgi?id=903881. The backtrace indicates that routine rtl_is_special(), which calls rtl_lps_leave() in three places was entered in atomic context. These direct calls are replaced by putting a request on the appropriate work queue.

2013-01-30mwifiex: fix incomplete scan in case of IE parsing errorBing Zhao
A scan request is split into multiple scan commands queued in scan_pending_q. Each scan command will be sent to firmware and its response is handlded one after another. If any error is detected while parsing IE in command response buffer the remaining data will be ignored and error is returned. We should check if there is any more scan commands pending in the queue before returning error. This ensures that we will call cfg80211_scan_done if this is the last scan command, or send next scan command in scan_pending_q to firmware.

2013-01-16iwlwifi: audit single frames from AGG queue in RSEmmanuel Grumbach
The rate scaling won't treat the information in a frame with IEEE80211_TX_CTL_AMPDU set if IEEE80211_TX_STAT_AMPDU is cleared. But all the frames coming from an AGG tx queue have IEEE80211_TX_CTL_AMPDU set, and IEEE80211_TX_STAT_AMPDU is set only if the frame was sent in an AMPDU. This means that all the data in frames in AGG tx queues that aren't sent as an AMPDU is thrown away. This is even more harmful when in bad link conditions, the frames are sent in an AMPDU and then finally sent as single frame. So a lot of failures weren't reported and the rate scaling got stuck in high rates leading to very poor connectivity. Fix that by clearing IEEE80211_TX_CTL_AMPDU when the frame isn't part of an AMPDU. This bug was introduced by 2eb81a40aa521035ff9c8c8309e482dff523f8c9 iwlwifi: don't clear CTL_AMPDU on frame status This fix basically reverts the aforementioned commit.

2013-01-11ath9k: fix rx flush handlingFelix Fietkau
Right now the rx flush is not doing anything useful on AR9003+, as it only works if the buffers in the rx FIFO have not been purged yet, as is done by ath_stoprecv. To fix this, always call ath_flushrecv from within ath_stoprecv before the FIFO is emptied, but still after the hw receive path has been stopped. This ensures that frames received (and ACKed by the hardware) shortly before a reset will be seen by the software, which should improve A-MPDU session stability.

2013-01-07b43: Fix firmware loading when driver is built into the kernelLarry Finger
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 6b6fa58) 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.

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.

2013-01-04mwifiex: check wait_event_interruptible return valueBing Zhao
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.

2013-01-04ath9k: Fix Kconfig for ATH9K_HTCVladimir Kondratiev
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 Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.

There's a bug in the currently released firmware version, the sequence control in the Tx response isn't updated in all cases. Take it from the packet as a workaround.

2013-01-03iwlwifi: fix PCIe interrupt handle return valueJohannes Berg
By accident, commit eb6476441bc2fecf6232a87d0313a85f8e3da7f4 ("iwlwifi: protect use_ict with irq_lock") changed the return value of the iwl_pcie_isr() function in case it handles an interrupt -- it now returns IRQ_NONE instead of IRQ_HANDLED. Put back the correct return value. Cc: stable@vger.kernel.org Reviewed-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
