USB: CDC ACM: Fix NULL pointer dereference

2012-09-12T02:37:13Z

commit 99f347caa4568cb803862730b3b1f1942639523f upstream. 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: emi62: remove __devinit* from the struct usb_device_id table

2012-09-12T02:37:13Z

commit 83957df21dd94655d2b026e0944a69ff37b83988 upstream. This structure needs to always stick around, even if CONFIG_HOTPLUG is disabled, otherwise we can oops when trying to probe a device that was added after the structure is thrown away. Thanks to Fengguang Wu and Bjørn Mork for tracking this issue down.

usb: gadget: u_ether: fix kworker 100% CPU issue with still used interfaces in eth_stop

2012-09-12T02:36:56Z

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 ; ifconfig down; ifconfig up - ping 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().

usb: serial: mos7840: Fixup mos7840_chars_in_buffer()

2012-09-12T02:36:55Z

commit 5c263b92f828af6a8cf54041db45ceae5af8f2ab upstream. * Use the buffer content length as opposed to the total buffer size. This can be a real problem when using the mos7840 as a usb serial-console as all kernel output is truncated during boot.

xhci: Add Etron XHCI_TRUST_TX_LENGTH quirk.

2012-09-12T02:36:53Z

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."

xhci: Increase reset timeout for Renesas 720201 host.

2012-09-12T02:36:52Z

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."

USB: echi-dbgp: increase the controller wait time to come out of halt.

2012-08-09T23:25:07Z

commit f96a4216e85050c0a9d41a41ecb0ae9d8e39b509 upstream. The default 10 microsecond delay for the controller to come out of halt in dbgp_ehci_startup is too short, so increase it to 1 millisecond. This is based on emperical testing on various USB debug ports on modern machines such as a Lenovo X220i and an Ivybridge development platform that needed to wait ~450-950 microseconds.
