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

2012-08-26T22:00:45Z

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()

2012-08-26T22:00:44Z

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. Signed-off-by: Mark Ferrell Signed-off-by: Greg Kroah-Hartman

IB/srp: Fix a race condition

2012-08-26T22:00:44Z

commit 220329916c72ee3d54ae7262b215a050f04a18fc upstream. Avoid a crash caused by the scmnd->scsi_done(scmnd) call in srp_process_rsp() being invoked with scsi_done == NULL. This can happen if a reply is received during or after a command abort.

pmac_zilog,kdb: Fix console poll hook to return instead of loop

2012-08-26T22:00:43Z

commit 38f8eefccf3a23c4058a570fa2938a4f553cf8e0 upstream. kdb <-> kgdb transitioning does not work properly with this UART driver because the get character routine loops indefinitely as opposed to returning NO_POLL_CHAR per the expectation of the KDB I/O driver API. The symptom is a kernel hang when trying to switch debug modes. Signed-off-by: Jason Wessel Cc: Alan Cox Signed-off-by: Greg Kroah-Hartman Signed-off-by: Greg Kroah-Hartman

USB: add USB_VENDOR_AND_INTERFACE_INFO() macro

2012-08-26T22:00:43Z

commit d81a5d1956731c453b85c141458d4ff5d6cc5366 upstream. A lot of Broadcom Bluetooth devices provides vendor specific interface class and we are getting flooded by patches adding new device support. This change will help us enable support for any other Broadcom with vendor specific device that arrives in the future. Only the product id changes for those devices, so this macro would be perfect for us: { USB_VENDOR_AND_INTERFACE_INFO(0x0a5c, 0xff, 0x01, 0x01) } Signed-off-by: Marcel Holtmann Signed-off-by: Gustavo Padovan Acked-by: Henrik Rydberg Signed-off-by: Greg Kroah-Hartman
