2008-08-22rt2x00: Implement HW encryptionIvo van Doorn
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.

2008-08-22replace net_device arguments with ieee80211_{local,sub_if_data} as appropriateJasper Bryant-Greene
This patch replaces net_device arguments to mac80211 internal functions with ieee80211_{local,sub_if_data} as appropriate. It also does the same for many 802.11s mesh functions, and changes the mesh path table to be indexed on sub_if_data rather than net_device. If the mesh part needs to be a separate patch let me know, but since mesh uses a lot of mac80211 functions which were being converted anyway, the changes go hand-in-hand somewhat. This patch probably does not convert all the functions which could be converted, but it is a large chunk and followup patches will be provided.

2008-08-22rfkill: introduce RFKILL_STATE_MAXHenrique de Moraes Holschuh
While it is interesting to not add last-enum-markers because it allows gcc to warn us of switch() statements missing a valid state, we really should be handling memory corruption on a rfkill state with default clauses, anyway. So add RFKILL_STATE_MAX and use it where applicable. It makes for safer code in the long run.

2008-08-22rfkill: add __must_check annotationsHenrique de Moraes Holschuh
rfkill is not a small, mere detail in wireless support. Once it starts supporting rfkill and users start counting on that support, a wireless device is at risk of operating in dangerous conditions should rfkill support fail to properly activate. Therefore, add the required __must_check annotations on some key functions of the rfkill API, for which the wireless drivers absolutely MUST handle the failure mode safely in order to avoid a potentially dangerous situation where the wireless transmitter is left enabled when the user don't want it to.

2008-08-22rfkill: add default global states (v2)Henrique de Moraes Holschuh
Add a second set of global states, "rfkill_default_states", to track the state that will be used when the first rfkill class of a given type is registered, and also to save "undo" information when rfkill_epo is called. Add a new exported function, rfkill_set_default(), which can be used by platform drivers to restore radio state saved by the platform across reboots or shutdown. Also, fix rfkill_epo to properly update rfkill_states, but still preserve a copy of the state so that we can undo the effect of rfkill_epo later if we want to. Add rfkill_restore_states() to restore rfkill_states from the copy. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-08-22ath5k: rates cleanupBruno Randolf
cleanup the rates structures used by ath5k. instead of separate driver and mac80211 rate structures we now setup a static ieee80211_rate array and use it directly. no conversion between two different rate structures has to be done any more. a lot of unused and confusing junk was deleted. renamed ath5k_getchannels into ath5k_setup_bands because this is what it does. rewrote it to copy the bitrates correctly for each band. this is necessary for running different hardware with the same driver (e.g. 5211 and 5212 based cards). add special handling of rates for AR5211 chipsets: it uses different rate codes for CCK rates (which are actually like the other chips but with a 0xF mask). setup a hardware code to rate index reverse mapping table for getting the rate index of received frames. the rates for control frames which have to be set in ath5k_hw_write_rate_duration are now in one single array. drivers/net/wireless/ath5k/ath5k.h: Changes-licensed-under: ISC drivers/net/wireless/ath5k/base.c: Changes-licensed-under: 3-Clause-BSD drivers/net/wireless/ath5k/base.h: Changes-licensed-under: 3-Clause-BSD drivers/net/wireless/ath5k/hw.c: Changes-licensed-under: ISC Signed-off-by: Bruno Randolf <br1@einfach.org> Signed-off-by: John W.

2008-08-20mm: xip/ext2 fix block allocation raceNick Piggin
XIP can call into get_xip_mem concurrently with the same file,offset with create=1. This usually maps down to get_block, which expects the page lock to prevent such a situation. This causes ext2 to explode for one reason or another. Serialise those calls for the moment. For common usages today, I suspect get_xip_mem rarely is called to create new blocks. In future as XIP technologies evolve we might need to look at which operations require scalability, and rework the locking to suit.
