This fixes an issue that a gadget driver (usb_f_fs) is possible to stop rx transactions after the usb-dmac is used because the following functions missed to set/check the "running" flag. - usbhsf_dma_prepare_pop_with_usb_dmac() - usbhsf_dma_pop_done_with_usb_dmac() So, if next transaction uses pio, the usbhsf_prepare_pop() can not start the transaction because the "running" flag is 0.

Patch "usb: gadget: f_fs: Use config_ep_by_speed()" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled usb: gadget: f_fs: Use config_ep_by_speed() to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: usb-gadget-f_fs-use-config_ep_by_speed.patch and it can be found in the queue-4.14 subdirectory.

In commit 2bfa0719ac2a ("usb: gadget: function: f_fs: pass companion descriptor along") there is a pointer arithmetic bug where the comp_desc is obtained as follows: comp_desc = (struct usb_ss_ep_comp_descriptor *)(ds + USB_DT_ENDPOINT_SIZE); Since ds is a pointer to usb_endpoint_descriptor, adding 7 to it ends up going out of bounds (7 * sizeof(struct usb_endpoint_descriptor), which is actually 7*9 bytes) past the SS descriptor. As a result the maxburst value will be read incorrectly, and the UDC driver will also get a garbage comp_desc (assuming it uses it). Since Felipe wrote, "Eventually, f_fs.c should be converted to use config_ep_by_speed() like all other functions, though", let's finally do it. This allows the other usb_ep fields to be properly populated, such as maxpacket and mult. It also eliminates the awkward speed-based descriptor lookup since config_ep_by_speed() does that already using the ones found in struct usb_function.

During _ffs_func_bind(), the received descriptors are evaluated to prepare for binding with the gadget in order to allocate endpoints and optionally set up OS descriptors. However, the high- and super-speed descriptors are only parsed based on whether the gadget_is_dualspeed() and gadget_is_superspeed() calls are true, respectively. This is a problem in case a userspace program always provides all of the {full,high,super,OS} descriptors when configuring a function. Then, for example if a gadget device is not capable of SuperSpeed, the call to ffs_do_descs() for the SS descriptors is skipped, resulting in an incorrect offset calculation for the vla_ptr when moving on to the OS descriptors that follow. This causes ffs_do_os_descs() to fail as it is now looking at the SS descriptors' offset within the raw_descs buffer instead. _ffs_func_bind() should evaluate the descriptors unconditionally, so remove the checks for gadget speed.

There are 2 control endpoint structures for DWC3. However, the driver only updates the OUT direction control endpoint structure during ConnectDone event. DWC3 driver needs to update the endpoint max packet size for control IN endpoint as well. If the max packet size is not properly set, then the driver will incorrectly calculate the data transfer size and fail to send ZLP for HS/FS 3-stage control read transfer.

The fcp_rsp_info structure as defined in the FC spec has an initial 3 bytes reserved field. The ibmvfc driver mistakenly defined this field as 4 bytes resulting in the rsp_code field being defined in what should be the start of the second reserved field and thus always being reported as zero by the driver. Ideally, we should wire ibmvfc up with libfc for the sake of code deduplication, and ease of maintaining standardized structures in a single place. However, for now simply fixup the definition in ibmvfc for backporting to distros on older kernels. Wiring up with libfc will be done in a followup patch.
