2012-04-11ath9k: add DFS pattern detectorZefir Kurtisi
This adds a DFS pattern detector to ath9k. It is fed with pulse events by the radar pulse detector and reports in place whether a pattern was detected. On detection, the result is reported as radar event to the DFS management component in the upper layer. Currently the ETSI DFS domain is supported with detector lines for the patterns defined by EN-301-893 v1.5.1. Support for FCC and JP will be added gradually. To include the pattern detector, ath9k must be built with support for DFS certified config flag set (CONFIG_ATH9K_DFS_CERTIFIED).

2012-04-11mac80211: add explicit monitor interface if neededJohannes Berg
The queue mapping redesign that I'm planning to do will break pure injection unless we handle monitor interfaces explicitly. One possible option would be to have the driver tell mac80211 about monitor mode queues etc., but that would duplicate the API since we already need to have queue assignments handled per virtual interface. So in order to solve this, have a virtual monitor interface that is added whenever all active vifs are monitors. We could also use the state of one of the monitor interfaces, but managing that would be complicated, so allocate separate state.

2012-04-11rtlwifi: Add missing DMA buffer unmapping for PCI driversLarry Finger
In https://bugzilla.kernel.org/show_bug.cgi?id=42976, a system with driver rtl8192se used as an AP suffers from "Out of SW-IOMMU space" errors. These are caused by the DMA buffers used for beacons never being unmapped.

2012-04-11rtlwifi: Preallocate USB read buffers and eliminate kalloc in read routineLarry Finger
The current version of rtlwifi for USB operations uses kmalloc to acquire a 32-bit buffer for each read of the device. When _usb_read_sync() is called with the rcu_lock held, the result is a "sleeping function called from invalid context" BUG. This is reported for two cases in https://bugzilla.kernel.org/show_bug.cgi?id=42775. The first case has the lock originating from within rtlwifi and could be fixed by rearranging the locking; however, the second originates from within mac80211. The kmalloc() call is removed from _usb_read_sync() by creating a ring buffer pointer in the private area and allocating the buffer data in the probe routine.

2012-04-10mac80211_hwsim: Fill timestamp beacon at the time it is transmittedJavier Cardona
Generate more acurate tsf values in hwsim by setting the tsf value on trasmitted beacons immediately before they are moved to the rx path. Also, adjust the beacon timestamp to be the time at which the first byte of the timestamp is transmitted. With these changes the observed tsf offset between two hwsim/mesh peers is 0 (unless the offset is modified via debugfs) Signed-off-by: Javier Cardona <javier@cozybit.com> Signed-off-by: John W.

2012-04-10mac80211: remove antenna_sel_tx TX info fieldJohannes Berg
This field is never set to anything non-zero in mac80211, so we should be able to remove it. Unfortunately though, the iwlwifi and iwlegacy drivers use it for their internal TX status processing (which shouldn't be using the rate control API to start with), so add a new field "status.antenna" for them, at least for now. In the future, I plan to use the new field to hold the hardware queue, while the SKB's queue mapping holds the AC. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.

2012-04-10mac80211: notify driver of rate control updatesJohannes Berg
Devices that have internal rate control need to be notified when the bandwidth or SMPS state changes just like external rate control algorithms get a notification now.

Linville <linville@tuxdriver.com>
2012-04-10mac80211: remove channel type argument from rate_updateJohannes Berg
The channel type argument to the rate_update() callback isn't really the correct way to give the rate control algorithm about the desired RX bandwidth of the peer. Remove this argument, and instead update the STA capabilities with 20/40 appropriately. The SMPS update done by this callback works in the same way, so this makes the callback cleaner.

2012-04-10mwifiex: don't use IEEE80211_MAX_QUEUESJohannes Berg
IEEE80211_MAX_QUEUES is an internal mac80211 value, it is not guaranteed to be always 4. The firmware API in mwifiex almost certainly doesn't care about mac80211 changing though, so mwifiex shouldn't use this value. Maybe it should use IEEE80211_NUM_ACS instead and that is what I'm doing here as at least that value will probably never change, but maybe it should have its own define instead.

2012-04-10mac80211: don't always advertise remain-on-channelJohannes Berg
Not all devices are really capable of implementing remain-on-channel, even if it is implemented in SW, as they can't necessarily deal with channel changes while associated. Remove the WIPHY_FLAG_HAS_REMAIN_ON_CHANNEL and add it only if either the driver has remain_on_channel implemented in the driver/device. Also add it to all drivers that advertise P2P right now since those definitely have to have it working.

2012-04-10bcma: fix build error on MIPS; implicit pcibios_enable_devicePaul Gortmaker
The following is seen during allmodconfig builds for MIPS: drivers/bcma/driver_pci_host.c:518:2: error: implicit declaration of function 'pcibios_enable_device' [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors make[3]: *** [drivers/bcma/driver_pci_host.o] Error 1 Most likey introduced by commit 49dc9577155576b10ff79f0c1486c816b01f58bf "bcma: add PCIe host controller" Add the header instead of implicitly assuming it will be present. Sounds like a good idea, but that alone doesn't fix anything. The real problem is that the Kconfig has settings related to whether PCI is possible, i.e. config BCMA_HOST_PCI_POSSIBLE bool depends on BCMA && PCI = y default y config BCMA_HOST_PCI bool "Support for BCMA on PCI-host bus" depends on BCMA_HOST_PCI_POSSIBLE ...but what is missing is that BCMA_DRIVER_PCI_HOSTMODE doesn't have any dependencies on the above.

Error log reporting does not belong to the transport layer, but to the op_mode loading the ucode, as it is the entity which knows about the ucode loaded, and what the error information means. Move device logging pointers from the transport layer to op_mode. With this change, transport layer only reports an error to the op_mode, which will figure out what to do with the error. This causes the driver to now dump out error logs when the command queue is stuck as well. Also, move the debugfs entry for event logs out of the transport layer and into op_mode.
