rt2x00: fix rfkill regression on rt2500pci As reported by Niels, starting rfkill polling during device probe (commit e2bc7c5, generally sane change) broke rfkill on rt2500pci device. I considered that bug as some initalization issue, which should be fixed on rt2500pci specific code. But after several attempts (see bug report for details) we fail to find working solution. Hence I decided to revert to old behaviour on rt2500pci to fix regression. Additionally patch also unregister rfkill on device remove instead of ifconfig down, what was another issue introduced by bad commit. Bug report: https://bugzilla.kernel.org/show_bug.cgi?id=73821 Fixes: e2bc7c5f3cb8 ("rt2x00: Fix rfkill_polling register function.")

rt2x00: add rt2x00_has_cap_* helpers The rt2x00 code directly accesses the 'cap_flags' field of 'struct rt2x00_dev' when checking presence of a given capability flag. The direct access needs long expressions which lowers readability of the code. Add a few helper functions which can be used to test device capabilities without directly accessing the cap_flags filed.

rt2x00: add queue_init callback to rt2x00_ops The driver uses static data structures for initializing specific fields of a given data queue. These static queue data descriptor structures are containing values which related to a given chipset. Even though the values are chip specific, the actual selection of the used structure is based on device specific vendor/product identifiers. This approach works, but it is not always reliable. Sometimes the vendor and/or device IDs of the PCI and USB devices contains improper values which makes it impossible to select the correct structure for such devices. The patch adds a new callback to tr2x00_ops which is called after the chipset detection is finished. This allows the drivers to do dynamic initialization of the data_queue structure for a given queue based on the actual chipset. After each driver implements the queue_init callback, the data_queue_desc structure will be removed.

rt2x00: Improve TX status handling for BlockAckReq frames Since rt2800 hardware isn't capable of reporting the TX status of BlockAckReq frames implement the TX status handling of BARs in rt2x00lib. We keep track of all BARs that are send out and try to match incoming BAs to the appropriate BARs. This allows us to report a more or less accurate TX status for BAR frames which in turn improves BA session stability. This is loosley based on Christian Lamparter's patch for carl9170 "carl9170: fix HT peer BA session corruption". We have to walk the list of pending BARs for every rx'red BA even though most BAs don't belong to any of these BARs as they are just acknowledging an AMPDU. To keep that overhead low use RCU which allows us to walk the list of pending BARs without the need to acquire a lock. This however requires us to _copy_ relevant information from the BAR (RA, TA, control field, start sequence number) into our BAR list entry.

rt2x00: rt2800usb: rework txstatus code Currently we read tx status register after each urb data transfer. As callback procedure also trigger reading, that causing we have many "threads" of reading status. To prevent that introduce TX_STATUS_READING flags, and check if we are already in process of sequential reading TX_STA_FIFO, before requesting new reads. Change timer to hrtimer, that make TX_STA_FIFO overruns less possible. Use 200 us for initial timeout, and then reschedule in 100 us period, this values probably have to be tuned. Make changes on txdone work. Schedule it from rt2800usb_tx_sta_fifo_read_completed() callback when first valid status show up. Check in callback if tx status timeout happens, and schedule work on that condition too. That make possible to remove tx status timeout from generic watchdog. I moved that to rt2800usb. Loop in txdone work, that should prevent situation when we queue work, which is already processed, and after finish work is not rescheduled again.

rt2x00: Fix sleep-while-atomic bug in powersaving code. The generic powersaving code that determines after reception of a frame whether the device should go back to sleep or whether is could stay awake was calling rt2x00lib_config directly from RX tasklet context. On a number of the devices this call can actually sleep, due to having to confirm that the sleeping commands have been executed successfully. Fix this by moving the call to rt2x00lib_config to a workqueue call.

To best support the set_antenna callback some modifications are needed in the diversity handling. We should never look at the default antenna settings to determine if software diversity is enabled. Instead we should set the diversity flag when possible, which will allow the link_tuner to automatically pick up the tuning.

rt2x00: Decrease association time for USB devices When powersaving is enabled, assocaition times are very high (for WPA2 networks, the time can easily be around the 3 seconds). This is caused, because the flushing of the queues takes too much time. Without the flushing callback mac80211 assumes a timeout of 100ms while scanning. Limit all flush waiting loops to the same maximum. We can apply this maximum by passing the drop status to the driver, which makes sure the driver performs extra actions during the waiting for the queue to become empty. After these changes, association times fall within the healthy range of ~0.6 seconds with powersaving enabled. The difference between association time between powersaving enabled and disabled is now only ~0.1 second (which can also be due to the measuring method).

rt2800usb: read TX_STA_FIFO asynchronously Trying to fix the "TX status report missed" warnings by reading the TX_STA_FIFO entries as quickly as possible. The TX_STA_FIFO is too small in hardware, thus reading it only from the workqueue is too slow and entries get lost. Start an asynchronous read of the TX_STA_FIFO directly from the TX URB completion callback (atomic context, thus it cannot use the blocking rt2800_register_read()). If the async read returns a valid FIFO entry, it is pushed into a larger FIFO inside struct rt2x00_dev, until rt2800_txdone() picks it up. A .tx_dma_done callback is added to struct rt2x00lib_ops to trigger the async read from the URB completion callback.

rt2x00: Split rt2x00dev->flags The number of flags defined for the rt2x00dev->flags field, has been growing over the years. Currently we are approaching the maximum number of bits which are available in the field. A secondary problem, is that one part of the field are initialized only during boot, because the driver requirements are initialized or device requirements are loaded from the EEPROM. In both cases, the flags are fixed and will not change during device operation. The other flags are the device state, and will change frequently. So far this resulted in the fact that for some flags, the atomic bit accessors are used, while for the others the non-atomic variants are used. By splitting the flags up into a "flags" and "cap_flags" we can put all flags which are fixed inside "cap_flags". This field can then be read non-atomically. In the "flags" field we keep the device state, which is going to be read atomically. This adds more room for more flags in the future, and sanitizes the field access methods.

rt2x00: Implement tx power temperature compensation rt2800 devices should adjust their tx power in accordance with the eeproms temperature calibration values. Add a new driver callback gain_calibration that is called every 4 seconds. The rt2800 gain calibration routine simply runs the tx power configuration that takes care of calculating the temperature compensation delta. We don't need to synchronize the calls to rt2800_config_txpower as they should all happen from mac80211's single threaded workqueue.

All drivers will drop frames if they fail to TX the frame, and they must also properly manage the queues (if they didn't, mac80211 would already warn). Removing the ability for drivers to return a BUSY value also allows significant cleanups of the TX TX handling code in mac80211.

rt2x00: Refactor beacon code to make use of start- and stop_queue This patch allows to dynamically remove beaconing interfaces without shutting beaconing down on all interfaces. The only place to start and stop beaconing are now the start- and stop_queue callbacks. Hence, we can remove some register writes during interface bring up (config_intf) and only write the correct sync mode to the register there. When multiple beaconing interfaces are present we should enable beaconing as soon as mac80211 enables beaconing on at least one of them. The beacon queue gets stopped when the last beaconing interface was stopped by mac80211. Therefore, introduce another interface counter to keep track ot the number of enabled beaconing interfaces and start or stop the beacon queue accordingly. To allow single interfaces to stop beaconing, add a new driver callback clear_beacon to clear a single interface's beacon without affecting the other interfaces. Don't overload the clear_entry callback for clearing beacons as that would introduce additional overhead (check for each TX queue) into the clear_entry callback which is used on the drivers TX/RX hotpaths. Furthermore, the write beacon callback doesn't need to enable beaconing anymore but since beaconing should be disabled while a new beacon is written or cleared we still disable beacon generation and enable it afterwards again in the driver specific callbacks. However, beacon related interrupts should not be disabled/enabled here, that's solely done from the start- and stop queue callbacks. It would be nice to stop the beacon queue just before the beacon update and enable it afterwards in rt2x00queue itself instead of the current implementation that relies on the driver doing the right thing. However, since start- and stop_queue are mutex protected we cannot use them for atomic beacon updates.

rt2x00: Move watchdog work to kernel work_queue The watchdog function must run on a work_queue which is independent of any other work inside rt2x00. The main reasons, being that a broken work on the mac80211 work_queue can otherwise prevent the watchdog to run (while in fact the watchdog could fix the issue). And on the other hand because the watchdog relies on the completion of the completion handlers for RX/TX which for the USB case, occur on the mac80211 workqueue. This fixes some "Queue %d failed to flush" errors, which were caused by the watchdog function waiting on the completion handler which was scheduled to run right after the watchdog.

rt2x00: Simplify Queue function arguments A lot of functions accept a struct rt2x00_dev combined with either a struct queue_entry or struct data_queue argument. This can be simplified by only passing on the queue/entry argument. In cases where rt2x00_dev and a sk_buff are send together, we can send the queue_entry instead. rt2x00usb_alloc_urb and rt2x00usb_free_urb have a bit of vague naming. Instead they allocate all the data which belongs to a rt2x00 data queue entry.

rt2x00: rework tx status handling in rt2800pci This patch changes the way tx status reports are handled by rt2800pci. Previously rt2800pci would sometimes lose tx status reports as the TX_STA_FIFO register is a fifo of 16 entries that can overflow in case we don't read it often/fast enough. Since interrupts are disabled in the device during the execution of the interrupt thread it happend sometimes under high network and CPU load that processing took too long and a few tx status reports were dropped by the hw. To fix this issue the TX_STA_FIFO register is read directly in the interrupt handler and stored in a kfifo which is large enough to hold all status reports of all used tx queues. To process the status reports a new tasklet txstatus_tasklet is used. Using the already used interrupt thread is not possible since we don't want to disable the TX_FIFO_STATUS interrupt while processing them and it is not possible to schedule the interrupt thread multiple times for execution. A tasklet instead can be scheduled multiple times which allows to leave the TX_FIFO_STATUS interrupt enabled while a previously scheduled tasklet is still executing. In short: All other interrupts are handled in the interrupt thread as before. Only the TX_FIFO_STATUS interrupt is partly handled in the interrupt handler and finished in the according tasklet. One drawback of this patch is that it duplicates some code from rt2800lib. However, that can be cleaned up in the future once the rt2800usb and rt2800pci tx status handling converge more. Using this patch on a Ralink RT3052 embedded board gives me a reliable wireless connection even under high CPU and network load. I've transferred several gigabytes without any queue lockups.

rt2x00: Check for specific changed flags when updating the erp config Previously rt2x00 was always updating all erp related config variables even though mac80211 might only have changed one. Hence, pass the changed flags to the config_erp driver callback so that the driver can limit the changes to the correct values. This fixes an issue in AP mode where the beacon interval is not initialized (and thus zero) but still sent to the hardware causing an interrupt storm on rt2800pci hanging the system.

rt2x00: Split watchdog check into a DMA and STATUS timeout The watchdog for rt2800usb triggers frequently causing all URB's to be canceled often enough to interrupt the normal TX flow. More research indicated that not the URB upload to the USB host were hanging, but instead the TX status reports. To correctly detect what is going on, we introduce Q_INDEX_DMA_DONE which is an index counter between Q_INDEX_DONE and Q_INDEX and indicates if the frame has been transfered to the device. This also requires the rt2x00queue timeout functions to be updated to differentiate between a DMA timeout (time between Q_INDEX and Q_INDEX_DMA_DONE timeout) and a STATUS timeout (time between Q_INDEX_DMA_DONE and Q_INDEX_DONE timeout) All Q_INDEX_DMA_DONE code was taken from the RFC from Helmut Schaa <helmut.schaa@googlemail.com> for the implementation for watchdog for rt2800pci.

rt2x00: Fix max TX power settings During initialization each driver reads the default TX power for each individual channel. However mac80211 only accepts the maximum value (which is also handled as default value). As a result, the TX power of the device was being limited to the default value, which is often quite low compared to the real maximum acceptable value. This patch allows each driver to set the maximum value on a per-channel basis which is forwarded to mac80211. The default value will be preserved for now, in case we want to update mac80211 to differentiate between the maximum and default txpower. This fixes bug complaining about limited TX power values like: https://bugzilla.kernel.org/show_bug.cgi?id=16358 Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Acked-by: Helmut Schaa <helmut.schaa@googlemail.com> Signed-off-by: John W.

rt2x00: Simplify arguments to rt2x00 driver callback functions write_tx_desc shouldn't pass a rt2x00dev and skb pointer, instead it should use the same format as other TX frame callback functions, which is passing the data_entry pointer which contains all the information which is needed to work on a TX frame. Most callers of the kick_tx_queue and kill_tx_queue already have the data_queue pointer, so rather then sending the QID with the given function, when the driver requests a new pointer to the data_queue, it is more efficient to just send the data_queue pointer directly.

Whereas the band was already provided directly within the rt2x00_dev structure.

rt2x00: Move USB tx/rx done handling to workqueue Move all TX and RX completion handling into a work structure, which is handeled on the mac80211 workqueue. This simplifies the code in rt2x00lib since it no longer needs to check if the device is USB or PCI to decide which mac80211 function should be used. In the watchdog some changes are needed since it can no longer rely on the TX completion function to be run while looping through the entries. (Both functions now work on the same workqueue, so this would deadlock). So the watchdog now waits for the URB to return, and handle the TX status report directly. As a side-effect, the debugfs entry for the RX queue now correctly displays the positions of the INDEX and INDEX_DONE counters. This also implies that it is not possible to perform checks like queue_empty() and queue_full() on the RX queue. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

rt2x00: Hardcode TX ack timeout and consume time The calculated values for the ACK timeout and ACK consume time are different then the values as used by the Legacy drivers. After testing from James Ledwith it appeared that the calculated values caused a high amount of TX failures, and the values from the Legacy drivers were the most optimal to prevent TX failure due to excessive retries. The symptoms of this problem: - Rate control module always falls back to 1Mbs - Low throughput when bitrate was fixed Possible side-effects (not confirmed but highly likely) - Problems with DHCP - Broken connections due to lack of probe response This should fix at least: Kernel bugzilla reports: [13362], [13009], [9273] Fedora bugzilla reports: [443203] but possible some additional bugs as well.

mac80211: allow configure_filter callback to sleep Over time, a whole bunch of drivers have come up with their own scheme to delay the configure_filter operation to a workqueue. To be able to simplify things, allow configure_filter to sleep, and add a new prepare_multicast callback that drivers that need the multicast address list implement. This new callback must be atomic, but most drivers either don't care or just calculate a hash which can be done atomically and then uploaded to the hardware non-atomically. A cursory look suggests that at76c50x-usb, ar9170, mwl8k (which is actually very broken now), rt2x00, wl1251, wl1271 and zd1211 should make use of this new capability.

rt2x00: Fix for race condition while update beacon The patch "Implement set_tim callback for all drivers" can cause kernel oops in rt73usb_write_beacon. The oops is caused by one of the following race conditions: * In case of two near calls to set_tim: rt2x00lib_beacondone_iter is cleaning the beacon skb, whereas rt73usb_write_beacon is still using it. * In case of two near updates of beacon: first as the result of set_tim and second as the result of a call from an application (e.g. hostapd). This patch fixes the race condition by rearranging the update logic and guarding rt2x00_intf->beacon->skb with a mutex.

rt2x00: Restrict interface between rt2x00link and drivers Restrict drivers to only access link_qual structure during link tuning. The contents of these fields are for the drivers and all fields are allowed to be changed to values the driver considers correct. This means that some fields need to be moved outside of this structure to restrict access only to rt2x00link itself. This allows some code to be moved outside of the rt2x00.h header and into rt2x00link.c. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

rt2x00: Reduce calls to bbp_read() The link_tuner() function will always call bbp_read() at the start of the function. Because this is an indirect register access has some costs attached to it (especially for USB hardware). We already store the value read from the register into the vgc_level value inside the link structure. Instead of reading from the register we can read that field directly and base the tuner on that value. This reduces the time the registers are locked with the csr_mutex and speeds up the link_tuner processing. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

rt2x00: Detect USB BULK in/out endpoints Instead of hardcoding the used in/out endpoints we should detect them by walking through all available endpoints. rt2800usb will gain the most out of this, because the legacy drivers indicate that there are multiple endpoints available. However this code might benefit at least rt73usb as well for the MIMO queues, and if we are really lucky rt2500usb will benefit because for the TX and PRIO queues. Even if rt2500usb and rt73usb do not get better performance after this patch, the endpoint detection still belongs to rt2x00usb, and it shouldn't hurt to always try to detect the available endpoints.

rt2x00: Fix race condition when using inderect registers Indirect registers require multiple calls to the CSR register in order to access the indirect registers. This must be protected under a lock to prevent race conditions which could cause invalid data to be returned when reading from the indirect register or silent failures when writing data to the indirect register. USB drivers where already protected under a mutex, so rename the mutex and make PCI drivers use the mutex as well. This now means that BBP and RF registers are no longer accessible in interrupt context. That is not a bad situation since the slow behavior of accessing those registers means we don't _want_ to access them in interrupt context either.

rt2x00: Fix BUG_ON() with antenna handling With the new configuration handling, and more specifically splitting the configuration of the antenna from the normal configuration steps allowed a BUG_ON() to be triggered in the driver because the SW_DIVERSITY was send to the driver. This fixes that by catching the value early in rt2x00config.c and replacing it with a sensible value. This also fixes a problem where the antenna is not being initialized at all when the radio is enabled. Since it no longer is part of the mac80211 configuration the only place where rt2x00 configured it was the SW diversity handler. Obviously this is broken for all non-diversity hardware and breaks SW diversity due to a broken initialization. When the radio is enabled the antenna will be configured once as soon as the config() callback function is called. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

rt2x00: Only configure hardware when radio is enabled Some hardware configuration registers such as antenna and channel configuration can only be written when the radio is enabled. Previously, we didn't consider this, so some configuration items could be set inconsistently after reenabling the radio. This patch changes the config() handler to only reprogram the hardware when the radio is enabled. Configuration changes that are made while the radio is off are postponed until the radio is switched back on. We also leave the radio turned off during initialization and only enable it when requested by mac80211. This allows us to get rid of the DIRTY_CONFIG flag, because the device is now guaranteed to be completely initialized when brought up by mac80211.

rt2x00: Force full register config after start() rt2x00 will only perform configuration changes from mac80211 when the configuration option has changed. This means it keeps track of the current active configuration and will check these values when the config() callback function is used. However this causes breakage when the interface has been brought down and up again, since all stored active values aren't reset while the registers might have. This is for example the case with rt61pci antenna registers which will jump to invalid values when the interface has been started. To make sure a full configuration takes place after the start() callback function, a new flag is added which will be checked during config() and skips the "what's changed" phase.

It also removes the old sequence number code because we noticed that only the driver or hardware can assign sequence numbers to non-QoS-data and especially management frames in a race-free manner because beacons aren't passed through mac80211's TX path. This patch also adds temporary code to the rt2x00 drivers to not break them completely, that code will have to be reworked for proper sequence numbers on beacons.

rt2x00: Fix lock dependency errror This fixes a circular locking dependency in the workqueue handling. The interface work task uses the mac80211 function ieee80211_iterate_active_interfaces() which grabs the RTNL lock. However when the interface is brough down, this happens under the RTNL lock as well, this causes problems because mac80211 will flush the workqueue during the ifdown event. This causes mac80211 to wait until the driver has completed all work which can't finish because it is waiting on the RTNL lock. This is fixed by moving rt2x00 workqueue tasks on a different workqueue, this workqueue can be flushed when the ieee80211_hw structure is removed by the driver (when the driver is unloaded) which does not happen under the RTNL lock.

rt2x00: Cleanup symbol exports With a bit of code moving to rt2x00lib within the TX and RX paths we can now remove a lot of EXPORT_SYMBOL_GPL() statements. This cleans up the interface between rt2x00lib and the drivers and has the additional benefit that rt2x00pci and rt2x00usb are trimmed down in size as well since they have less to do.

rt2x00: Replace statically allocated DMA buffers with mapped skb's. The current PCI drivers require a lot of pre-allocated DMA buffers. Reduce this by using dynamically mapped skb's (using pci_map_single) instead of the pre- allocated DMA buffers that are allocated at device start-up time. At the same time move common RX path code into rt2x00lib from rt2x00pci and rt2x00usb, as the RX paths now are now almost the same.

rt2x00: Centralize RX packet alignment handling in rt2x00lib. When rt2x00pci will be switched over to dynamically mapped skb's instead of statically allocated DMA buffers, it no longer can handle alignment of RX packets in a copy step, and needs to implement the same scheme as rt2x00usb does. In order to make the patch on dynamically mapped skb's smaller, already centralize the alignment handling into rt2x00lib. This allows us to move more code in rt2x00lib, and thus remove code duplication between rt2x00usb and rt2x00pci.

rt2x00: Don't kick TX queue after each frame TX queues shouldn't be kicked after each frame that is put into the queue. This could cause problems during RTS and CTS-to-self as well as with fragmentation. In all those cases you want all frames to be send out in a single burst. Off course we shouldn't let the queue fill up entirely, thus we introduce a 10% threshold which, when reached, will force the frames to be send out regardless of the frame. In addition we should prevent queues to become full in such a way that the tx() handler can fail. Instead of stopping the queue when it is full, we should stop it when it is below the threshold.

This split is required to properly allow mac80211 to move its tx_control structure into the skb->cb array. The rt2x00queue_create_tx_descriptor() function will read all tx control information and convert it into a rt2x00 TX descriptor information structure. After that function is complete, we have all information we needed from the tx control structure and are free to start writing into the skb->cb array for our own purposes. rt2x00queue_write_tx_descriptor() will be in charge of really sending the TX descriptor to the hardware and kicking the TX queue.

rt2x00: Fix queue related oops in case of deselected mac80211 multi-queue feature. With the integration of the mac80211 multiqueue patches it has become possible that the mac80211 layer modifies the number of TX queues that is stored inside the ieee80211_hw structure, especially when multi-queue is not selected. The rt2x00 drivers are not well suited to handle that situation, as they allocate the queue structures before mac80211 has modified the number of queues it is going to use, and also expect the number of allocated queues to match the hardware implementation. Hence, ensure that rt2x00 maintains by itself the number of queues that the hardware supports, and, at the same time, making is not dependent on the preservation of contents inside a mac80211 structure.

cfg80211 API for channels/bitrates, mac80211 and driver conversion This patch creates new cfg80211 wiphy API for channel and bitrate registration and converts mac80211 and drivers to the new API. The old mac80211 API is completely ripped out. All drivers (except ath5k) are updated to the new API, in many cases I expect that optimisations can be done. Along with the regulatory code I've also ripped out the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be unnecessary if the hardware simply gives us whatever channels it wants to support and we then enable/disable them as required, which is pretty much required for travelling. Additionally, the patch adds proper "basic" rate handling for STA mode interface, AP mode interface will have to have new API added to allow userspace to set the basic rate set, currently it'll be empty... However, the basic rate handling will need to be moved to the BSS conf stuff. I do expect there to be bugs in this, especially wrt. transmit power handling where I'm basically clueless about how it should work.

This changes the way rt2x00 handles the active interface drastically. Copy ieee80211_bss_conf to the this rt2x00_intf structure during the bss_info_changed() callback function. This will allow us to reference it later, and removes the requirement for the device flag SHORT_PREAMBLE flag which is interface specific. Drivers receive the option to give the maximum number of virtual interfaces the device can handle. Virtual interface support: rt2400pci: 1 sta or 1 ap, * monitor interfaces rt2500pci: 1 sta or 1 ap, * monitor interfaces rt2500usb: 1 sta or 1 ap, * monitor interfaces rt61pci: 1 sta or 4 ap, * monitor interfaces rt73usb: 1 sta or 4 ap, * monitor interfaces At the moment none of the drivers support AP and STA interfaces simultaneously, this is a hardware limitation so future support will be very unlikely. Each interface structure receives its dedicated beacon entry, with this we can easily work with beaconing while multiple master mode interfaces are currently active. The configuration handlers for the MAC, BSSID and type are often called together since they all belong to the interface configuration. Merge the 3 configuration calls and cleanup the API between rt2x00lib and the drivers. While we are cleaning up the interface configuration anyway, we might as well clean up the configuration handler as well. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

rt2x00: Driver requiring firmware should select crc algo The driver should select what CRC algorithm is required when performing a checksum on the firmware. rt61pci & rt73usb require crc-itu-t rt2800pci & rt2800usb require crc-ccitt Legacy 2800pci/usb driver uses crc-itu-t + bit order reversion, but that is just inefficient especially since the end result is the same as a different algorithm which is also available as library. ;) Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

rt2x00: Queue handling overhaul This introduces a big queue handling overhaul, this also renames "ring" to "queues". Move queue handling into rt2x00queue.c and the matching header, use Kerneldoc to improve rt2x00 library documentation. Access to the queues is now protected under a spinlock, this to prevent race conditions which could corrupt the indexing system of the queue. Each queue entry allocates x bytes for driver/device specific data, this cleans up the queue structure significantly and improves code readability. rt2500usb no longer needs 2 entries in the beacon queue to correctly send out the guardian byte. This is now handled in the entry specific structure. rt61 and rt73 now use the correct descriptor size for beacon frames, since this data is written into the registers not the entire TXD descriptor was used but instead of a subset of it named TXINFO. Finally this also fixes numerous other bugs related to incorrect beacon handling or beacon related code. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

mac80211: add unified BSS configuration This patch (based on Ron Rindjunsky's) creates a framework for a unified way to pass BSS configuration to drivers that require the information, e.g. for implementing power save mode. This patch introduces new ieee80211_bss_conf structure that is passed to the driver via the new bss_info_changed() callback when the BSS configuration changes. This new BSS configuration infrastructure adds the following new features: * drivers are notified of their association AID * drivers are notified of association status and replaces the erp_ie_changed() callback. The patch also does the relevant driver updates for the latter change.

mac80211: dont use interface indices in drivers This patch gets rid of the if_id stuff where possible in favour of a new per-virtual-interface structure "struct ieee80211_vif". This structure is located at the end of the per-interface structure and contains a variable length driver-use data area. This has two advantages: * removes the need to look up interfaces by if_id, this is better for working with network namespaces and performance * allows drivers to store and retrieve per-interface data without having to allocate own lists/hash tables Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

[PATCH] rt2x00: Fix rfkill handling As reported by Modestas Vainius, enabling rkfill in 1 driver and disabling it in a second could cause a NULL pointer exception when the rfkill-disabled driver still sets the CONFIG_SUPPORT_HW_BUTTON flag. Furthermore, rfkill expects the timeout as a value in milliseconds instead of jiffies. Also increase the timeout to a second, since this 250ms would be overkill. Also the flag DEVICE_ENABLED_RADIO_HW is causing problems for devices which do not support the hardware button while rfkill is enabled in the driver. To remidy this we should inverse the flag and its meaning, rename the flag to DEVICE_DISABLED_RADIO_HW this means that by default the radio is enabled by the hardware button (if present) and can only be disabled explicitely.

[PATCH] mac80211: revamp interface and filter configuration Drivers are currently supposed to keep track of monitor interfaces if they allow so-called "hard" monitor, and they are also supposed to keep track of multicast etc. This patch changes that, replaces the set_multicast_list() callback with a new configure_filter() callback that takes filter flags (FIF_*) instead of interface flags (IFF_*). For a driver, this means it should open the filter as much as necessary to get all frames requested by the filter flags. Accordingly, the filter flags are named "positively", e.g. FIF_ALLMULTI. Multicast filtering is a bit special in that drivers that have no multicast address filters need to allow multicast frames through when either the FIF_ALLMULTI flag is set or when the mc_count value is positive. At the same time, drivers are no longer notified about monitor interfaces at all, this means they now need to implement the start() and stop() callbacks and the new change_filter_flags() callback. Also, the start()/stop() ordering changed, start() is now called *before* any add_interface() as it really should be, and stop() after any remove_interface(). The patch also changes the behaviour of setting the bssid to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed and the filter flag FIF_BCN_PRBRESP_PROMISC introduced. This is a lot more efficient for hardware like b43 that supports it and other hardware can still set the BSSID to all-ones.
