| * USB: CDC ACM: Fix NULL pointer dereferenceSven Schnelle2012-08-171-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | If a device specifies zero endpoints in its interface descriptor, the kernel oopses in acm_probe(). Even though that's clearly an invalid descriptor, we should test wether we have all endpoints. This is especially bad as this oops can be triggered by just plugging a USB device in.

| * USB: qcserial: fix port handling on Gobi 1K and 2K+Dan Williams2012-08-161-18/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bjorn's latest patchset does break Gobi 1K and 2K because on both devices as it claims usb interface 0. That's because usbif 0 is not handled in the switch statement, and thus the if0 gets claimed when it should not. So let's just make things even simpler yet, and handle both the 1K and 2K+ cases separately. This patch should not affect the new Sierra device support, because those devices are matched via interface-specific matching and thus should never hit the composite code.

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().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Existing implementation of tegra_ehci_remove() calls usb_put_hcd(hcd) first and then iounmap(hcd->regs). usb_put_hcd() implementation calls hcd_release() which frees up memory allocated for hcd. As iounmap is trying to unmap hcd->regs, after hcd getting freed up, warning messages were observed during unload of USB. Hence fixing it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We cannot unconditionally access any usb-serial port specific data from the interface driver. Both supending and resuming may happen after the port has been removed and portdata is freed. Treat ports with no portdata as closed ports to avoid a NULL pointer dereference on resume. No need to kill URBs for removed ports on suspend, avoiding the same NULL pointer reference there.

| * usb: serial: prevent suspend/resume from racing against probe/removeBjørn Mork2012-08-101-2/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some usb-serial drivers may access port data in their suspend/ resume functions. Such drivers must always verify the validity of the data as both suspend and resume can be called both before usb_serial_device_probe and after usb_serial_device_remove. But the port data may be invalidated during port_probe and port_remove. This patch prevents the race against suspend and resume by disabling suspend while port_probe or port_remove is running.

| * usb: usb_wwan: replace release and disconnect with a port_remove hookBjørn Mork2012-08-105-48/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Doing port specific cleanup in the .port_remove hook is a lot simpler and safer than doing it in the USB driver .release or .disconnect methods. The removal of the port from the usb-serial bus will happen before the USB driver cleanup, so we must be careful about accessing port specific driver data from any USB driver functions. This problem surfaced after the commit 0998d0631 device-core: Ensure drvdata = NULL when no driver is bound which turned the previous unsafe access into a reliable NULL pointer dereference.

This affects the core retention too. The same commit logic needs to be revisted adhering to hwmod and device tree framework. for now, this commit id 354ab8567ae3107a8cbe7228c3181990ba598aac titled "Fix OMAP EHCI suspend/resume failure (i693)" reverted. This patch is validated on BeagleXM with NFS support over usb ethernet and USB mass storage and other device detection.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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."

Hi Greg, Here's four patches for 3.6. Most are marked for stable as well. The first one makes the xHCI driver load properly on newer Rensas hosts. The next two fix issues with the Etron host incorrectly marking short transfers as successful, and avoiding log warning spam for hosts that make the same mistake. The last patch fixes a really nasty xHCI driver bug that could cause general protection faults when devices stall transfers. Sarah Sharp
| | * xhci: Fix bug after deq ptr set to link TRB.Sarah Sharp2012-08-081-14/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

If page splitting is used, it is possible that pages will be allocated from the PFMEMALLOC reserve without propagating this information to the skb. This patch propagates page->pfmemalloc from pages allocated for fragments to the skb. It works by reintroducing and expanding the skb_alloc_page() API to take an skb. If the page was allocated from pfmemalloc reserves, it is automatically copied. If the driver allocates the page before the skb, it should call skb_propagate_pfmemalloc() after the skb is allocated to ensure the flag is copied properly. Failure to do so is not critical. The resulting driver may perform slower if it is used for swap-over-NBD or swap-over-NFS but it should not result in failure.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the changes in the random tree, IRQF_SAMPLE_RANDOM is now a no-op; interrupt randomness is now collected unconditionally in a very low-overhead fashion; see commit 775f4b297b. The IRQF_SAMPLE_RANDOM flag was scheduled to be removed in 2009 on the feature-removal-schedule, so this patch is preparation for the final removal of this flag.
