* iwlwifi: add bad length check for WEP keysEmmanuel Grumbach2008-06-14
| | | | | | | | | | | This patch adds a check for bad length in set key flow. This solves the Oops reported by Thomas Backlund, Joonwoo Park and Ian Schram. It also adds some debug printing that can be useful.

* iwlwifi: Fix mode changes (ad-hoc <--> managed)Assaf Krauss2008-06-14
| | | | | | | | | | | | This fix allows to move between modes (ad-hoc to managed, and vice versa). Since mode changes can only be done while driver is down, check for ibss support can only be made when the channel is set (afte the driver goes up).

* iwlwifi enabling IBSS (Ad-Hoc) modeAssaf Krauss2008-06-14
| | | | | | | | | | | | | | | | | | | This patch enables ibss mode. It consists of two changes upon entering ibss mode: 1. Removing the redundant line which clears the driver's station table. This line creates a discrepancy between the driver and the FW's station table. This prevented the generation of beacons. 2. Assigning a default value to priv's assoc_id. Normally given by an AP in STA mode, this field is used as an indication for association. Being 0, it prevented normal TX flow. 3. Remove a redundant ADD_STA command that cause uCode error. 4. Delay the set_mode until after the uCode is ready.

* rt2x00: Rework alignment check.Gertjan van Wingerde2008-06-14
| | | | | | | | | | | | | | Rework the alignment check in rt2x00dev.c to be independent of any potential alignment measures that may be taken before. Just check whether the payload is aligned based on the pointer addresses. Note: This is preparatory for the dynamically mapped skb buffers for the PCI drivers, as these need 4-byte alignment instead of the currently enforced offset by 2 bytes.

* rt2x00: Fix double usage of skb->cb in USB RX path.Gertjan van Wingerde2008-06-14
| | | | | | | | | | | | | | It is not safe to use the skb->cb area for both the rxd and skb_frame_desc data at the same time, while they occupy an overlapping piece of memory. This can lead to hard to trace crashes as pointers within skb_frame_desc are pointing into nowhere, or the rxd data is overwritten with non-sense.

* rt2x00: Centralize RX packet alignment handling in rt2x00lib.Gertjan van Wingerde2008-06-14
| | | | | | | | | | | | | | | | 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 frameIvo van Doorn2008-06-14
| | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | rt2x00usb_kick_tx_queue() will loop over all entries within the INDEX_DONE->INDEX range and kick each entry which is pending to be kicked. This makes the kick_tx_queue approach work the same as with the PCI drivers which will allow for more code generalisation into rt2x00lib.

| | | | | | | | | | | | | qid should be initialized to QID_BEACON and QID_ATIM for the beacon and atim quue. This makes checking for a particular queue much saner, and it shouldn't harm, because the only places where the value is send to the hardware, we are allowed to send any value we want since it is only used as argument in the TX done register.

* rt2x00: Calculate register offset during compile timeIvo van Doorn2008-06-14
| | | | | | | | | | | | | | | | | | | | | By using __ffs() the register offsets were always calculated at run-time which all FIELD32/FIELD16 definitions were builtin constants. This means we can heavily optimize the register handling by allowing GCC to do all the work during compilation. Add some compile_ffs() macros to perform the calculation at compile time. After this each rt2x00 module size is reduced by ~2500 bytes. And the stack size of several functions is reduced as well which further limits the number of rt2x00 results in 'make checkstack'. v2: Merge GertJan's bugfix of patch [1/11] directly into this patch       instead of providing it as seperate patch. v3: Add extra parentheses when bitshifting __x Signed-off-by: Gertjan van Wingerde <gwingerde@kpnplanet.nl> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
