The functionality to keep the device awake until it is done with the rx of any mcast/bcast frames which are pending on AP should also be added to the hardwares which support auto sleep feature. This patch fixes frequent failures in ARP resolution when it is initiated by the other end. Currently auto sleep is enabled only for ar9003 in ath9k. Signed-off-by:

The intent here is to test that "sta_id_r" is a valid pointer. We do this same test later on in the function. Btw iwl_add_bssid_station() is called from two places and "sta_id_r" is a valid pointer from both callers. Signed-off-by:

We should use the same buffer size we set up for DMA also in the hardware descriptor. Previously we used common->rx_bufsize for setting up the DMA mapping, but used skb_tailroom(skb) for the size we tell to the hardware in the descriptor itself. The problem is that skb_tailroom(skb) can give us a larger value than the size we set up for DMA before. This allows the hardware to write into memory locations not set up for DMA. In practice this should rarely happen because all packets should be smaller than the maximum 802.11 packet size. On the tested platform rx_bufsize is 2528, and we allocated an skb of 2559 bytes length (including padding for cache alignment) but sbk_tailroom() was 2592. Just consistently use rx_bufsize for all RX DMA memory sizes. Also use the return value of the descriptor setup function. Cc: stable@kernel.org Signed-off-by:

We tried to squeeze as much AR9003 support into this kernel release cycle but there are a few features which are still being tested and developed. Some of these features are critical to the stable operation of AR9003 so for now disable AR9003 support all together. This will get re-enabled once all necessary features are in place but very likely will not happen for 2.6.35. Reviewed-by:

The current frame length used by the driver for RX frames is the SPI bus transfer length. This length has padding bytes, which do not belong to the WLAN frame. As there is no other length information in the WLAN frame except the skb length this problem caused for instance extra ESSID's to be listed at the end of scan results (IE id 0) with zero length. Fix the frame length by removing padding. Signed-off-by:

It is possible for internal scan to race against itself if the device is not returning the scan results from first requests. What happens in this case is the cleanup done during the abort of the first internal scan also cleans up part of the new scan, causing it to access memory it shouldn't. Here are details: * First internal scan is triggered and scan command sent to device. * After seven seconds there is no scan results so the watchdog timer triggers a scan abort. * The scan abort succeeds and a SCAN_COMPLETE_NOTIFICATION is received for failed scan. * During processing of SCAN_COMPLETE_NOTIFICATION we clear STATUS_SCANNING and queue the "scan_completed" work. ** At this time, since the problem that caused the internal scan in first place is still present, a new internal scan is triggered. The behavior at this point is a bit different between 2.6.34 and 2.6.35 since 2.6.35 has a lot of this synchronized. The rest of the race description will thus be generalized. ** As part of preparing for the scan "is_internal_short_scan" is set to true. * At this point the completion work for fist scan is run. As part of this there is some locking missing around the "is_internal_short_scan" variable and it is set to "false". ** Now the second scan runs and it considers itself a real (not internal0 scan and thus causes problems with wrong memory being accessed. The fix is twofold. * Since "is_internal_short_scan" should be protected by mutex, fix this in scan completion work so that changes to it can be serialized. * Do not queue a new internal scan if one is in progress.

Fix some issues introduced in batch skb dequeuing for input_pkt_queue. The primary issue it that the queue head must be incremented only after a packet has been processed, that is only after __netif_receive_skb has been called. This is needed for the mechanism to prevent OOO packet in RFS. Also when flushing the input_pkt_queue and process_queue, the process queue should be done first to prevent OOO packets. Because the input_pkt_queue has been effectively split into two queues, the calculation of the tail ptr is no longer correct. The correct value would be head+input_pkt_queue->len+process_queue->len. To avoid this calculation we added an explict input_queue_tail in softnet_data. The tail value is simply incremented when queuing to input_pkt_queue. Signed-off-by:

When GRO produces fraglist entries, and the resulting skb hits an interface that is incapable of TSO but capable of FRAGLIST, we end up producing a bogus packet with gso_size non-zero.

This adds support for a new copper device for 82599, device id 0x151c. This 82599 10GBase-T device uses the PHY's internal temperature sensor to guard against over-temp conditions. In this scenario the PHY will be put in a low power mode and link will no longer be able to transmit or receive any data. When this occurs, the over-temp interrupt is latched and driver logs this error message. A HW reset or power cycle is required to clear this status. Signed-off-by:
