The receive tasklet was not disabled on port close, which could lead to corruption of receive lists on consecutive port open. In particular, read urbs could be re-submitted before port open, added to free list in open, and then added a second time to the free list in the completion handler. cdc-acm.c: Entering acm_tty_open. cdc-acm.c: acm_control_msg: rq: 0x22 val: 0x3 len: 0x0 result: 0 cdc-acm.c: Entering acm_rx_tasklet cdc-acm.c: acm_rx_tasklet: sending urb 0xf50da280, rcv 0xf57fbc24, buf 0xf57fbd64 cdc-acm.c: set line: 115200 0 0 8 cdc-acm.c: acm_control_msg: rq: 0x20 val: 0x0 len: 0x7 result: 7 cdc-acm.c: acm_tty_close cdc-acm.c: acm_port_down cdc-acm.c: acm_control_msg: rq: 0x22 val: 0x0 len: 0x0 result: 0 cdc-acm.c: acm_ctrl_irq - urb shutting down with status: -2 cdc-acm.c: acm_rx_tasklet: sending urb 0xf50da300, rcv 0xf57fbc10, buf 0xf57fbd50 cdc-acm.c: Entering acm_read_bulk with status -2 cdc_acm 4-1:1.1: Aborting, acm not ready cdc-acm.c: Entering acm_read_bulk with status -2 cdc_acm 4-1:1.1: Aborting, acm not ready cdc-acm.c: acm_rx_tasklet: sending urb 0xf50da380, rcv 0xf57fbbfc, buf 0xf57fbd3c cdc-acm.c: acm_rx_tasklet: sending urb 0xf50da400, rcv 0xf57fbbe8, buf 0xf57fbd28 cdc-acm.c: acm_rx_tasklet: sending urb 0xf50da480, rcv 0xf57fbbd4, buf 0xf57fbd14 cdc-acm.c: acm_rx_tasklet: sending urb 0xf50da900, rcv 0xf57fbbc0, buf 0xf57fbd00 cdc-acm.c: acm_rx_tasklet: sending urb 0xf50da980, rcv 0xf57fbbac, buf 0xf57fbcec cdc-acm.c: acm_rx_tasklet: sending urb 0xf50daa00, rcv 0xf57fbb98, buf 0xf57fbcd8 cdc-acm.c: acm_rx_tasklet: sending urb 0xf50daa80, rcv 0xf57fbb84, buf 0xf57fbcc4 cdc-acm.c: acm_rx_tasklet: sending urb 0xf50dab00, rcv 0xf57fbb70, buf 0xf57fbcb0 cdc-acm.c: acm_rx_tasklet: sending urb 0xf50dab80, rcv 0xf57fbb5c, buf 0xf57fbc9c cdc-acm.c: acm_rx_tasklet: sending urb 0xf50dac00, rcv 0xf57fbb48, buf 0xf57fbc88 cdc-acm.c: acm_rx_tasklet: sending urb 0xf50dac80, rcv 0xf57fbb34, buf 0xf57fbc74 cdc-acm.c: acm_rx_tasklet: sending urb 0xf50dad00, rcv 0xf57fbb20, buf 0xf57fbc60 cdc-acm.c: acm_rx_tasklet: sending urb 0xf50dad80, rcv 0xf57fbb0c, buf 0xf57fbc4c cdc-acm.c: acm_rx_tasklet: sending urb 0xf50da880, rcv 0xf57fbaf8, buf 0xf57fbc38 cdc-acm.c: Entering acm_tty_open. cdc-acm.c: acm_control_msg: rq: 0x22 val: 0x3 len: 0x0 result: 0 cdc-acm.c: Entering acm_rx_tasklet cdc-acm.c: acm_rx_tasklet: sending urb 0xf50da280, rcv 0xf57fbc24, buf 0xf57fbd64 cdc-acm.c: Entering acm_tty_write to write 3 bytes, cdc-acm.c: Get 3 bytes... cdc-acm.c: acm_write_start susp_count: 0 cdc-acm.c: Entering acm_read_bulk with status 0 ------------[ cut here ]------------ WARNING: at /home/johan/src/linux/linux-2.6/lib/list_debug.c:57 list_del+0x10c/0x120() Hardware name: Vostro 1520 list_del corruption. next->prev should be f57fbc10, but was f57fbaf8 Modules linked in: cdc_acm Pid: 3, comm: ksoftirqd/0 Not tainted 2.6.37+ #39 Call Trace: [<c103c7e2>] warn_slowpath_common+0x72/0xa0 [<c11dd8ac>] ?

| * USB: Fix 'bad dma' problem on WDM device disconnectRobert Lukassen2011-03-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the WDM class driver a disconnect event leads to calls to usb_free_coherent to put back two USB DMA buffers allocated earlier. The call to usb_free_coherent uses a different size parameter (desc->wMaxCommand) than the corresponding call to usb_alloc_coherent (desc->bMaxPacketSize0). When a disconnect event occurs, this leads to 'bad dma' complaints from usb core because the USB DMA buffer is being pushed back to the 'buffer-2048' pool from which it has not been allocated. This patch against the most recent linux-2.6 kernel ensures that the parameters used by usb_alloc_coherent & usb_free_coherent calls in cdc-wdm.c match.

| * ehci-hcd: Bug fix: don't set a QH's Halt bitAlan Stern2011-03-231-12/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1453) fixes a long-standing bug in the ehci-hcd driver. There is no need to set the Halt bit in the overlay region for an unlinked or blocked QH. Contrary to what the comment says, setting the Halt bit does not cause the QH to be patched later; that decision (made in qh_refresh()) depends only on whether the QH is currently pointing to a valid qTD. Likewise, setting the Halt bit does not prevent completions from activating the QH while it is "stopped"; they are prevented by the fact that qh_completions() temporarily changes qh->qh_state to QH_STATE_COMPLETING. On the other hand, there are circumstances in which the QH will be reactivated _without_ being patched; this happens after an URB beyond the head of the queue is unlinked. Setting the Halt bit will then cause the hardware to see the QH with both the Active and Halt bits set, an invalid combination that will prevent the queue from advancing and may even crash some controllers. Apparently the only reason this hasn't been reported before is that unlinking URBs from the middle of a running queue is quite uncommon. However Test 17, recently added to the usbtest driver, does exactly this, and it confirms the presence of the bug. In short, there is no reason to set the Halt bit for an unlinked or blocked QH, and there is a very good reason not to set it. Therefore the code that sets it is removed.

* USB: Move runtime PM callbacks to usb_device_pm_opsRafael J. Wysocki2011-03-183-12/+11Star
| | | | | | | | | | | | USB defines usb_device_type pointing to usb_device_pm_ops that provides system-wide PM callbacks only and usb_bus_type pointing to usb_bus_pm_ops that provides runtime PM callbacks only. However, the USB runtime PM callbacks may be defined in usb_device_pm_ops which makes it possible to drop usb_bus_pm_ops and will allow us to consolidate the handling of subsystems by the PM core code.

Add USB_SS_MULT macro to access Mult field of bmAttributes, at Sarah's suggestion. This patch should be queued for the 2.6.36 and 2.6.37 stable trees, since those were the first kernels to have isochronous support for SuperSpeed devices.

Eliminate a check for the link TRB type in find_trb_seg(). We know that there will always be a link TRB at the end of a segment, so xhci_segment->trbs[TRBS_PER_SEGMENT - 1] will always have a link TRB type.

This includes updating the cycle bit (TRB ownership bit) if we have moved the dequeue pointer past a link TRB with the toggle cycle bit set. When we're trying to find the new dequeue segment, find_trb_seg() is supposed to keep track of whether we've passed any link TRBs with the toggle cycle bit set. However, this while loop's body while (cur_seg->trbs > trb || &cur_seg->trbs[TRBS_PER_SEGMENT - 1] < trb) { Will never get executed if the ring only contains one segment. find_trb_seg() will return immediately, without updating the new cycle bit. Since find_trb_seg() has no idea where in the segment the TD that stalled was, make the caller, xhci_find_new_dequeue_state(), check for this special case and update the cycle bit accordingly. This patch should be queued to kernels all the way back to 2.6.31. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com> Tested-by: Takashi Iwai <tiwai@suse.de> Cc: stable@kernel.org

To do that, the driver issues a Set TR Dequeue Pointer command, which will complete some time later. Takashi was having issues with USB 1.1 audio devices that stalled, and his analysis of the code was that the old code would not update the xHCI driver's ring dequeue pointer after the command completes. However, the dequeue pointer is set in xhci_find_new_dequeue_state(), just before the set command is issued to the hardware. Setting the dequeue pointer before the Set TR Dequeue Pointer command completes is a dangerous thing to do, since the xHCI hardware can fail the command. Instead, store the new dequeue pointer in the xhci_virt_ep structure, and update the ring's dequeue pointer when the Set TR dequeue pointer command completes. While we're at it, make sure we can't queue another Set TR Dequeue Command while the first one is still being processed. This just won't work with the internal xHCI state code. I'm still not sure if this is the right thing to do, since we might have a case where a driver queues multiple URBs to a control ring, one of the URBs Stalls, and then the driver tries to cancel the second URB. There may be a race condition there where the xHCI driver might try to issue multiple Set TR Dequeue Pointer commands, but I would have to think very hard about how the Stop Endpoint and cancellation code works. Keep the fix simple until when/if we run into that case. This patch should be queued to kernels all the way back to 2.6.31.

There isn't support for USB 3.0 device suspend yet, so make khubd leave autosuspend disabled for USB 3.0 hubs. Make sure that USB 3.0 roothubs still have autosuspend enabled, since that path in the xHCI driver works fine. Signed-off-by: Sarah Sharp <sarah.a.sharp@linux.intel.com>
