2008-06-14rt2x00: Fix double usage of skb->cb in USB RX path.Gertjan van Wingerde
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. Fix it by copying the rxd to a small buffer on the stack. Signed-off-by: Gertjan van Wingerde <gwingerde@kpnplanet.nl> Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-06-14rt2x00: Centralize RX packet alignment handling in rt2x00lib.Gertjan van Wingerde
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.

2008-06-14rt2x00: Don't kick TX queue after each frameIvo van Doorn
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.

2008-06-14rt2x00: Move generic TX frame writing code into rt2x00queueIvo van Doorn

2008-06-14rt2x00: Implement rt2x00usb_kick_tx_queue()Ivo van Doorn
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.

2008-06-14rt2x00: Fix queue initializationIvo van Doorn
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.

2008-06-14rt2x00: Calculate register offset during compile timeIvo van Doorn
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.

2008-06-09tg3: Fix 5761 WOLMatt Carlson
On 5761 non-e devices, two problems prevent the administrator from overriding the WOL settings in the device's NVRAM. The first problem is that GPIO 0 and GPIO 2 have been swapped. This change prevented the administrator from turning on WOL when it is disabled in NVRAM. The fix is to add a new path for the 5761 that swaps the two GPIOs in the code as well. The second problem is that GPIO 1 could not be toggled by the driver because the GPIO is shared with the debug UART GPIO. This will prevent the administrator from being able to turn WOL off if it was enabled in NVRAM. The fix is to always disable the debug UART after a GRC reset.

The problem is that the added flow control check will always fail if flow control is set to autoneg and either RX or TX (or both) flow control is enabled. The driver defaults to setting flow control to autoneg and advertises both RX and TX flow control. The fix is to remove the errant check.

This fixes an issus that made "iwconfig eth1 power on" non-working. When we get a "PS sleep" event, we have to confirm this to the firmware. The confirm happens with a command, but this command is special: the firmware won't send us a response. if_cs_host_to_card() is setting priv->dnld_sent anyway, so this variable stayed at DNLD_DATA_SENT and was never cleared back. Now I put the special knowledge that the CMD_802_11_PS_MODE with CMD_SUBCMD_SLEEP_CONFIRMED doesn't need to need a response by directly clearing the dnld_sent state in lbs_send_confirmsleep().

Make sure the direct scan happens eventually, and as a bonus ensure that the passive scan worker is cleaned up when appropriate. The change of request_passive_scan form a struct work to struct delayed_work is only to make the set_wx_scan() code a bit simpler, it's still only used with a delay of 0 to match previous behavior.

2008-06-04l2tp: Fix possible oops if transmitting or receiving when tunnel goes downJames Chapman
Some problems have been experienced in the field which cause an oops in the pppol2tp driver if L2TP tunnels fail while passing data. The pppol2tp driver uses private data that is referenced via the sk->sk_user_data of its UDP and PPPoL2TP sockets. This patch makes sure that the driver uses sock_hold() when it holds a reference to the sk pointer. This affects its sendmsg(), recvmsg(), getname(), [gs]etsockopt() and ioctl() handlers. Tested by ISP where problem was seen. System has been up 10 days with no oops since running this patch. Without the patch, an oops would occur every 1-2 days.
