2021-01-26usb: dwc2: Do not update data length if it is 0 on inbound transfersGuenter Roeck1-7/+8
The DWC2 documentation states that transfers with zero data length should set the number of packets to 1 and the transfer length to 0. This is not currently the case for inbound transfers: the transfer length is set to the maximum packet length. This can have adverse effects if the chip actually does transfer data as it is programmed to do. Follow chip documentation and keep the transfer length set to 0 in that situation.

2021-01-26usb/c67x00: Replace tasklet with workDavidlohr Bueso2-6/+8
Tasklets have long been deprecated as being too heavy on the system by running in irq context - and this is not a performance critical path. If a higher priority process wants to run, it must wait for the tasklet to finish before doing so. c67x00_do_work() will now run in process context and have further concurrency (tasklets being serialized among themselves), but this is done holding the c67x00->lock, so it should be fine. Furthermore, this patch fixes the usage of the lock in the callback as otherwise it would need to be irq-safe.

2021-01-26usb: xhci-mtk: fix unreleased bandwidth dataIkjoon Jang5-39/+111
xhci-mtk needs XHCI_MTK_HOST quirk functions in add_endpoint() and drop_endpoint() to handle its own sw bandwidth management. It stores bandwidth data into an internal table every time add_endpoint() is called, and drops those in drop_endpoint(). But when bandwidth allocation fails at one endpoint, all earlier allocation from the same interface could still remain at the table. This patch moves bandwidth management codes to check_bandwidth() and reset_bandwidth() path. To do so, this patch also adds those functions to xhci_driver_overrides and lets mtk-xhci to release all failed endpoints in reset_bandwidth() path.

Add support for MaxLinear/Exar USB to Serial converters. This driver only supports XR21V141X series but it can be extended to other series from Exar as well in future. This driver is inspired from the initial one submitted by Patong Yang: https://lore.kernel.org/r/20180404070634.nhspvmxcjwfgjkcv@advantechmxl-desktop While the initial driver was a custom tty USB driver exposing whole new serial interface ttyXRUSBn, this version is completely based on USB serial core thus exposing the interfaces as ttyUSBn. This will avoid the overhead of exposing a new USB serial interface which the userspace tools are unaware of. The Exar XR21V141X can be used in either ACM mode using the cdc-acm driver or in "custom driver" mode in which further features such as hardware and software flow control, GPIO control and in-band line-status reporting are available. In ACM mode the device always enables RTS/CTS flow control, something which could prevent transmission in case the CTS input isn't wired up corrently.

As per the kernel doc for usb_ep_dequeue(), it states that "this routine is asynchronous, that is, it may return before the completion routine runs". And indeed since v5.0 the dwc3 gadget driver updated its behavior to place dequeued requests on to a cancelled list to be given back later after the endpoint is stopped. The free_ep() was incorrectly assuming that a request was ready to be freed after calling dequeue which results in a use-after-free in dwc3 when it traverses its cancelled list. Fix this by moving the usb_ep_free_request() call to the callback itself in case the ep is disabled.
