* rt2x00: Fix TX short preamble detectionIvo van Doorn2009-01-121-11/+0
| | | | | | | | | | | | The short preamble mode was not correctly detected during TX, rt2x00 used the rate->hw_value_short field but mac80211 is not using this field that way. Instead the flag IEEE80211_TX_RC_USE_SHORT_PREAMBLE should be used to determine if the frame should be send out using short preamble or not.

* rt2x00: Move crypto TX descriptor handling to rt2x00crypto.cIvo van Doorn2008-12-051-1/+8
| | | | | | | | | | | | | | | Move all code which determines the right TX descriptor fields specific to crypto support into rt2x00crypto.c. This makes the code in rt2x00queue more simpler and better concentrates all crypto code into a single location. With this we can also remove some ifdefs in rt2x00queue.c since the code inside the ifdef is either very small, or only calling empty functions (see empty function definitions in rt2x00lib.h).

* rt2x00: Cleanup TX/RX entry handlingIvo van Doorn2008-11-211-2/+10
| | | | | | | | | | | | | | | | Merge the callback functions init_txentry() and init_rxentry(). This makes life in rt2x00lib a lot simpler and we can cleanup several functions. rt2x00pci contained "fake" FIELD definitions for descriptor words. This is not flexible since it assumes the driver will always have the same field to indicate if a driver is available or not. This should be dependent on the driver, and we should add a callback function for this. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* rt2x00: Fix BUG_ON() with antenna handlingIvo van Doorn2008-11-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | 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: Implement HW encryptionIvo van Doorn2008-08-221-0/+47
| | | | | | | | | | | | | | | Various rt2x00 devices support hardware encryption. Most of them require the IV/EIV to be generated by mac80211, but require it to be provided seperately instead of within the frame itself. This means that rt2x00lib should extract the data from the frame and place it in the frame descriptor. During RX the IV/EIV is provided in the descriptor by the hardware which means that it should be inserted into the frame by rt2x00lib.

This patch will move the function to the TX handlers, and move all duplicate code into rt2x00queue.c. After this change the descriptor helper functions from rt2x00queue.c no longer need to be exported outside of rt2x00lib and can be declared static.

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.

Change data_len and desc_len to unsigned short to save another 4 bytes in skb_frame_desc. Note that this was the only location where the data_len and desc_len was not yet treated as unsigned short. This trim is required to help mac80211 with adding the TX control and TX status informtation into the skb->cb structure. When that happens, drivers will have approximately 40 bytes left to use freely. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

This could lead to a NULL pointer fault when rt2x00 suspended, but polldev send a request, because the csr_addr is NULL.

This can be enabled through a per-driver configuration option which will automatically enable the generic handler in rt2x00lib. This has been enabled for rt2500usb and rt73usb for the moment since the led class will call set_brightness in irq context which will not work correctly with the usb drivers who need to sleep.

* | rt2x00: Rate structure overhaulIvo van Doorn2008-02-291-0/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent changes to the rate structure registration broke rt2x00, the hw_value was reduced from 32bits to 16bits while rt2x00 used the full 32bits. However the way rt2x00 used the value was inflexible and needed to be changed anyway. This patch creates a array containing information for each rate, the hw_value passed to mac80211 is the index value for that array including a field to indicate if short preamble should be enabled.

Delete the interface structure and replace it with a per-interface structure. 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: Queue handling overhaulIvo van Doorn2008-02-291-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] rt2x00: Fix rfkill handlingIvo van Doorn2007-10-101-8/+2
| | | | | | | | | | | | | | | | | | | | | | 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 configurationJohannes Berg2007-10-101-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
