This deviate double bufferring design that expect to trigger interrupt at half and full. If interrupt is trggered at 0 and 5, when upper layer pass through data faster then u_ether driver can free up, then the data flow start clogging from g_len=6 till g_len=9 and no interrupt is triggered to free up memory to consume data from upper layer as illustrated below.

in eth_stop commit b1b552a69b8805e7e338074a9e8b670b4a795218 upstream. This patch fixes an issue introduced by patch: 72c973d usb: gadget: add usb_endpoint_descriptor to struct usb_ep Without this patch we see a kworker taking 100% CPU, after this sequence: - Connect gadget to a windows host - load g_ether - ifconfig up <ip>; ifconfig down; ifconfig up - ping <windows host> The "ifconfig down" results in calling eth_stop(), which will call usb_ep_disable() and, if the carrier is still ok, usb_ep_enable(): usb_ep_disable(link->in_ep); usb_ep_disable(link->out_ep); if (netif_carrier_ok(net)) { usb_ep_enable(link->in_ep); usb_ep_enable(link->out_ep); } The ep should stay enabled, but will not, as ep_disable set the desc pointer to NULL, therefore the subsequent ep_enable will fail. This leads to permanent rescheduling of the eth_work() worker as usb_ep_queue() (called by the worker) will fail due to the unconfigured endpoint. We fix this issue by saving the ep descriptors and re-assign them before usb_ep_enable().

2012-08-26xhci: Fix bug after deq ptr set to link TRB.Sarah Sharp
commit 50d0206fcaea3e736f912fd5b00ec6233fb4ce44 upstream. This patch fixes a particularly nasty bug that was revealed by the ring expansion patches. The bug has been present since the very beginning of the xHCI driver history, and could have caused general protection faults from bad memory accesses. The first thing to note is that a Set TR Dequeue Pointer command can move the dequeue pointer to a link TRB, if the canceled or stalled transfer TD ended just before a link TRB. The function to increment the dequeue pointer, inc_deq, was written before cancellation and stall support was added. It assumed that the dequeue pointer could never point to a link TRB. It would unconditionally increment the dequeue pointer at the start of the function, check if the pointer was now on a link TRB, and move it to the top of the next segment if so. This means that if a Set TR Dequeue Point command moved the dequeue pointer to a link TRB, a subsequent call to inc_deq() would move the pointer off the segment and into la-la-land. It would then read from that memory to determine if it was a link TRB. Other functions would often call inc_deq() until the dequeue pointer matched some other pointer, which means this function would quite happily read all of system memory before wrapping around to the right pointer value. Often, there would be another endpoint segment from a different ring allocated from the same DMA pool, which would be contiguous to the segment inc_deq just stepped off of. inc_deq would eventually find the link TRB in that segment, and blindly move the dequeue pointer back to the top of the correct ring segment. The only reason the original code worked at all is because there was only one ring segment. With the ring expansion patches, the dequeue pointer would eventually wrap into place, but the dequeue segment would be out-of-sync. On the second TD after the dequeue pointer was moved to a link TRB, trb_in_td() would fail (because the dequeue pointer and dequeue segment were out-of-sync), and this message would appear: ERROR Transfer event TRB DMA ptr not part of current TD This fixes bugzilla entry 4333 (option-based modem unhappy on USB 3.0 port: "Transfer event TRB DMA ptr not part of current TD", "rejecting I/O to offline device"), https://bugzilla.kernel.org/show_bug.cgi?id=43333 and possibly other general protection fault bugs as well. This patch should be backported to kernels as old as 2.6.31. A separate patch will be created for kernels older than 3.4, since inc_deq was modified in 3.4 and this patch will not apply.

2012-08-26xhci: Switch PPT ports to EHCI on shutdown.Sarah Sharp
commit e95829f474f0db3a4d940cae1423783edd966027 upstream. The Intel desktop boards DH77EB and DH77DF have a hardware issue that can be worked around by BIOS. If the USB ports are switched to xHCI on shutdown, the xHCI host will send a spurious interrupt, which will wake the system. Some BIOS will work around this, but not all. The bug can be avoided if the USB ports are switched back to EHCI on shutdown. The Intel Windows driver switches the ports back to EHCI, so change the Linux xHCI driver to do the same. Unfortunately, we can't tell the two effected boards apart from other working motherboards, because the vendors will change the DMI strings for the DH77EB and DH77DF boards to their own custom names. One example is Compulab's mini-desktop, the Intense-PC. Instead, key off the Panther Point xHCI host PCI vendor and device ID, and switch the ports over for all PPT xHCI hosts. The only impact this will have on non-effected boards is to add a couple hundred milliseconds delay on boot when the BIOS has to switch the ports over from EHCI to xHCI. This patch should be backported to kernels as old as 3.0, that contain the commit 69e848c2090aebba5698a1620604c7dccb448684 "Intel xhci: Support EHCI/xHCI port switching."

2012-08-26xhci: Increase reset timeout for Renesas 720201 host.Sarah Sharp
commit 22ceac191211cf6688b1bf6ecd93c8b6bf80ed9b upstream. The NEC/Renesas 720201 xHCI host controller does not complete its reset within 250 milliseconds. In fact, it takes about 9 seconds to reset the host controller, and 1 second for the host to be ready for doorbell rings. Extend the reset and CNR polling timeout to 10 seconds each. This patch should be backported to kernels as old as 2.6.31, that contain the commit 66d4eadd8d067269ea8fead1a50fe87c2979a80d "USB: xhci: BIOS handoff and HW initialization."

2012-08-26xhci: Add Etron XHCI_TRUST_TX_LENGTH quirk.Sarah Sharp
commit 5cb7df2b2d3afee7638b3ef23a5bcb89c6f07bd9 upstream. Gary reports that with recent kernels, he notices more xHCI driver warnings: xhci_hcd 0000:03:00.0: WARN Successful completion on short TX: needs XHCI_TRUST_TX_LENGTH quirk? We think his Etron xHCI host controller may have the same buggy behavior as the Fresco Logic xHCI host. When a short transfer is received, the host will mark the transfer as successfully completed when it should be marking it with a short completion. Fix this by turning on the XHCI_TRUST_TX_LENGTH quirk when the Etron host is discovered. Note that Gary has revision 1, but if Etron fixes this bug in future revisions, the quirk will have no effect. This patch should be backported to kernels as old as 2.6.36, that contain a backported version of commit 1530bbc6272d9da1e39ef8e06190d42c13a02733 "xhci: Add new short TX quirk for Fresco Logic host."
