usb: usbip: set buffer pointers to NULL after free 2017-07-12T13:01:03+00:00 Michael Grzeschik m.grzeschik@pengutronix.de 2017-05-22T11:02:44+00:00 19adf93ccd555ac499ec160b4c4e181185b0c1c3 commit b3b51417d0af63fb9a06662dc292200aed9ea53f upstream. The usbip stack dynamically allocates the transfer_buffer and setup_packet of each urb that got generated by the tcp to usb stub code. As these pointers are always used only once we will set them to NULL after use. This is done likewise to the free_urb code in vudc_dev.c. This patch fixes double kfree situations where the usbip remote side added the URB_FREE_BUFFER.

USB: usbip: fix nonconforming hub descriptor 2017-06-24T05:11:15+00:00 Johan Hovold johan@kernel.org 2017-05-10T16:18:26+00:00 9ae5dac225e28ce165464d8880ecbc147708e12b commit ec963b412a54aac8e527708ecad06a6988a86fb4 upstream. Fix up the root-hub descriptor to accommodate the variable-length DeviceRemovable and PortPwrCtrlMask fields, while marking all ports as removable (and leaving the reserved bit zero unset). Also add a build-time constraint on VHCI_HC_PORTS which must never be greater than USB_MAXCHILDREN (but this was only enforced through a KConfig constant). This specifically fixes the descriptor layout whenever VHCI_HC_PORTS is greater than seven (default is 8).
