usb(4): Fix for use after free in combination with EVDEV_SUPPORT.

2021-11-03T17:39:23Z

When EVDEV_SUPPORT was introduced, the USB transfers may be running after the main FIFO is closed. In connection to this a race may appear which can lead to use-after-free scenarios. Fix this for all FIFO consumers by initializing and resetting the FIFO queues under the lock used by the client. Then the client driver will see an empty queue in all cases a race may appear.

Fix busdma resource leak on usb device detach.

2021-10-06T16:08:34Z

When a usb device is detached, usb_pc_dmamap_destroy() called bus_dmamap_destroy() while the map was still loaded. That's harmless on x86 architectures, but on all other platforms it causes bus_dmamap_destroy() to return EBUSY and leak away any memory resources (including bounce buffers) associated with the mapping, as well as any allocated map structure itself. This change introduces a new is_loaded flag to the usb_page_cache struct to track whether a map is loaded or not. If the map is loaded, bus_dmamap_unload() is called before bus_dmamap_destroy() to avoid leaking away resources.

Refactor CTL datamove KPI.

2021-03-15T02:45:05Z

- Make frontends call unified CTL core method ctl_datamove_done() to report move completion. It allows to reduce code duplication in differerent backends by accounting DMA time in common code. - Add to ctl_datamove_done() and be_move_done() callback samethr argument, reporting whether the callback is called in the same context as ctl_datamove(). It allows for some cases like iSCSI write with immediate data or camsim frontend write save one context switch, since we know that the context is sleepable. - Remove data_move_done() methods from struct ctl_backend_driver, unused since forever.
