The EHCI driver does some bounds checking when it's scheduling an iTD for an active endpoint. It sets the local variable start to stream->next_uframe and moves that variable further in the schedule if necessary. However, the driver fails to do anything with start before jumping to the ready label and setting the URB's starting frame to stream->next_uframe. Alan Stern confirms the EHCI driver should set stream->next_uframe to start before jumping. Signed-off-by:

Alan Stern authored
This patch (as1294) fixes a problem that has plagued users for several kernel releases. Some USB mass-storage devices don't return any sense data when they encounter certain kinds of errors. The SCSI layer interprets this to mean that the operation should be retried, and the same thing happens -- over and over again with no limit. In some circumstances (such as when a bus reset occurs) that is the right thing to do, but not here. The patch checks for this condition (a transport failure with no sense data) and changes the result code to DID_ERROR and the sense code to Hardware Error. This does get only a limited number of retries, and so the command will fail relatively quickly instead of getting stuck in an infinite loop. This fixes a large part of Bugzilla #14118.

The generic usbserial driver in Linux 2.6.31 halts its receiving channel in response to throttle requests from the line discipline. Unfortunately it drops the contents of the first URB received after throttling takes effect. This patch corrects that problem. Signed-off-by:

This patch (as1293) fixes a problem with the ipaq serial driver. It tries to bind to all the interfaces, even those that don't have enough endpoints. The symptom is an invalid memory reference and oops when the device is plugged in. Signed-off-by:

When the host controller dies or is removed while a device is plugged in, the USB core will attempt to deallocate the struct usb_device. That will call into xhci_free_dev(). This function used to attempt to submit a disable slot command to the host controller and clean up the device structures when that command returned. Change xhci_free_dev() to skip the command submission and just free the memory if the host controller died. Signed-off-by:

When the host controller dies (e.g. it is removed from a PCI card slot), the xHCI driver cannot expect commands to complete. The buggy code this patch fixes would mark an URB as canceled and then expect the URB to be completed when the stop endpoint command completed. That would never happen if the host controller was dead, so the USB core would just hang in the disconnect code. If the host controller died, and the driver asks to cancel an URB, free any structures associated with that URB and immediately give it back. Signed-off-by:

This patch (as1295) fixes a recently-added bug in the USB serial core. If certain kinds of errors occur during probing, the core may call a serial driver's release method without previously calling the attach method. This causes some drivers (io_ti in particular) to perform an invalid memory access. The patch adds a new flag to keep track of whether or not attach has been called. Signed-off-by:

Remove superfluous error checks in completion handler: - No need to check private data and urb pointers as we check urb-status before dereferencing priv (which is not freed until urb has been killed on close). - No need to check tty as it is checked again when processing. - No need to check urb->number_of_packets on bulk urb. Note that both private data and tty are checked again before processing (possibly from work queue which also is cancelled on close). Signed-off-by:
