* iwlagn: use PCI_DMA_* for pci_* operationsJohn W. Linville2011-06-281-6/+6
| | | | | | | | | "iwlagn: map command buffers BIDI" uses the DMA_* enumerations for DMA directions, even though the pci_* DMA API is still in use.

* libertas_sdio: handle spurious interruptsDaniel Drake2011-06-031-5/+16
| | | | | | | | | | | | | | | | | | | Commit 06e8935febe687e2a561707d4c7ca4245d261dbe adds an IRQ handling optimization for single-function SDIO cards like this one, but at the same time exposes a small hardware bug. During hardware init, an interrupt is generated with (apparently) no source. Previously, mmc threw this interrupt away, but now (due to the optimization), the mmc layer passes this onto libertas, before it is ready (and before it has enabled interrupts), causing a crash. Work around this hardware bug by registering the IRQ handler later and making it capable of handling interrupts with no cause. The change that makes the IRQ handler registration happen later actually eliminates the spurious interrupt as well. Signed-off-by: Daniel Drake <dsd@laptop.org> Signed-off-by: John W.

Problem here is that usb_bulk_msg() on interrupt endpoint selfcorrects the call and changes requested pipe to interrupt type (see usb_bulk_msg). However with usb_interrupt_msg() on bulk endpoint does not correct the pipe type to bulk, but instead URB is submitted with interrupt type pipe. So pre-2.6.39 used usb_bulk_msg() and therefore worked with both endpoint types, however in 2.6.39 usb_interrupt_msg() with bulk endpoint causes ohci_hcd to fail submitted URB instantly with -ENOSPC and preventing zd1211rw from working with OHCI. Fix this by detecting endpoint type and using correct endpoint/pipe types for URB. Also fix asynchronous zd_usb_iowrite16v_async() to use right URB type on 'EP 4 OUT'.

| | | | | | | | | | | | | | | | Fix kernel oops when trying to use passive scheduled scans. The reason was that in passive scans there are no SSIDs, so there was a NULL pointer dereference. To solve the problem, we now check the number of SSIDs provided in the sched_scan request and only access the list if there's one or more (ie. passive scan is not forced).

| | | | | | | | | | | | | | | | | Before this patch, the command sequence number is being set before lbs_queue_cmd() adds the command to the queue. However, lbs_queue_cmd() sometimes forces commands to queue-jump (e.g. CMD_802_11_WAKEUP_CONFIRM). It currently does this without considering that sequence numbers might need adjusting to keep things running in order.

| * ath9k: set 40 Mhz rate only if hw is configured in ht40Rajkumar Manoharan2011-05-261-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Whenever there is a channel width change from 40 Mhz to 20 Mhz, the hardware is reconfigured to ht20. Meantime before doing the rate control updation, the packets are being transmitted are selected rate with IEEE80211_TX_RC_40_MHZ_WIDTH. While transmitting ht40 rate packets in ht20 mode is causing baseband panic with AR9003 based chips. ==== BB update: BB status=0x02001109 ==== ath: ** BB state: wd=1 det=1 rdar=0 rOFDM=1 rCCK=1 tOFDM=0 tCCK=0 agc=2 src=0 ** ath: ** BB WD cntl: cntl1=0xffff0085 cntl2=0x00000004 ** ath: ** BB mode: BB_gen_controls=0x000033c0 ** ath: ** BB busy times: rx_clear=99%, rx_frame=0%, tx_frame=0% ** ath: ==== BB update: done ==== Cc: stable@kernel.org Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.

| | | | | | | | | | | | | | | | | | | | While receiving unsupported rate frame rx state machine gets into a state 0xb and if phy_restart happens in that state, BB would go hang. If RXSM is in 0xb state after first bb panic, ensure to disable the phy_restart. Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

| * rtlwifi: Use order 2 RX buffer allocation only if necessaryLarry Finger2011-05-261-0/+7
| | | | | | | | | | | | | | | | | | | | Although a previous fix handles the kernel panics that result from failure to allocate a new RX buffer, memory fragmentation can be reduced if the amsdu_8k capability is disabled as new buffers need only be of O(0), not O(2).

| * rtlwifi: Fix kernel panic resulting from RX buffer allocation failureLarry Finger2011-05-261-13/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To handle amsdu_8k capability, the PCI routine of this driver must allocate receive buffers of order 2. Under heavy load, this causes fragmentation of memory. The present code releases the current buffer before checking to see if a new one is availble. Recovery from allocation failures is not possible, which results in kernel panics. The fix is to reorder the code to check that a new buffer can be allocated before the old one is released. If not possible, the received frame is dropped and the old one is reused. Without this change, it is impossible to transfer a 2 GB file without a kernel panic.

| * mwifiex: correct event header lengthYogesh Ashok Powar2011-05-261-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While decoding received event packet from firmware, 4 bytes of interface header are already removed unconditionally. So for handling event only 4 more bytes needs to be pulled. This is achieved by changing event header length to 4. Almost all the events, except BA stream related and AMSDU aggregation control events, do not have the payload in their event skb. Such events handling depends only on the event ID. This event ID is the first four bytes of the event skb, which is copied to a separate variable before pulling the skb header. Hence event handling worked only for those events that didn't have payload in event skb. This patch fixes the broken event path of the events with payload in their event skb without harming existing working event path for the events without payload.
