Furthermore, on module removal the udc data is accessed although the release function is already triggered by usb_del_gadget_udc() early in the function. Fix by rewriting the release and remove functions, basically moving all the cleanup into the release function, and doing the completion only in the module removal case. The patch fixes omap_udc module probe with a failing gadged, and also allows the removal of omap_udc. Tested by running "modprobe omap_udc; modprobe -r omap_udc" in a loop.

This is fine for diag transfers because the read/write function is not waiting for completion. But in case of IPC transfers, the read/write function waits for completion. If the transfer fails for some reason, then it will do a kref_put as well, along with the completion callback. This leads to double put of kref counter leading to null pointer dereference from diag_bridge_disconnect(on cable disconnect). Fix this by doing kref_put in the completion callback only if the URB is submitted successfully. Else do it from the error handling in read/write functions.

As a side effect the change also removes a potential division by zero in u_audio_iso_complete() function, if there is a race with uac_pcm_hw_free(), which sets prm->period_size to 0.

Comparing to legacy f_uac1 function implementation it doesn't require any real Audio codec to be present on the device. In f_uac1 audio streams are simply sinked to and sourced from a virtual ALSA sound card created using u_audio API. Legacy f_uac1 approach is to write audio samples directly to existing ALSA sound card f_uac1 approach is more generic/flexible one - create an ALSA sound card that represents USB Audio function and allows to be used by userspace application that may choose to do whatever it wants with the data received from the USB Host and choose to provide whatever it wants as audio data to the USB Host. f_uac1 also has capture support (gadget->host) thanks to easy implementation via u_audio. By default, capture interface has 48000kHz/2ch configuration, same as playback channel has. f_uac1 descriptors naming convention uses f_uac2 driver naming convention that makes it more common and meaningful. Comparing to f_uac1_legacy, the f_uac1 doesn't have volume/mute functionality. This is because the f_uac1 volume/mute feature unit was dummy implementation since that driver creation (2009) and never had any real volume control or mute functionality, so there is no any difference here. Since f_uac1 functionality, exposed interface to userspace (virtual ALSA card), input parameters are so different comparing to f_uac1_legacy, that there is no any reason to keep them in the same file/module, and separate function was created.

Visible changes: - add uac_params structure to pass audio paramteres for g_audio_setup - make ALSA sound card's name configurable - add [in/out]_ep_maxpsize - allocate snd_uac_chip structure during g_audio_setup - add u_audio_[start/stop]_[capture/playback] functions This change differs from opensource patch in that it does not modify the UAC2 driver to use u_audio helper file for ALSA sound card support.

On host site it looks like: [424339.017711] 21:1:1: usb_set_interface failed (-32) Since host can't set altsetting 1, it can't start playing audio. In order to fix it implemented get_alt along with minor improvements (error conditions checking) similar to what existing f_uac2 has.

Don't allow USB3 U1 or U2 if the latency to wake up from the U-state reaches the service interval for a periodic endpoint. This is according to xhci 1.1 specification section 4.23.5.2 extra note: "Software shall ensure that a device is prevented from entering a U-state where its worst case exit latency approaches the ESIT." Allowing too long exit latencies for periodic endpoint confuses xHC internal scheduling, and new devices may fail to enumerate with a "Not enough bandwidth for new device state" error from the host.

Some lower volume SanDisk Ultra Flair in 16GB, which the VID:PID is in 0781:5591, will aggressively request LPM of U1/U2 during runtime, when using this thumb drive as the OS installation key we found the device will generate failure during U1 exit path making it dropped from the USB bus, this causes a corrupted installation in system at the end. i.e., [ 166.918296] hub 2-0:1.0: state 7 ports 7 chg 0000 evt 0004 [ 166.918327] usb usb2-port2: link state change [ 166.918337] usb usb2-port2: do warm reset [ 166.970039] usb usb2-port2: not warm reset yet, waiting 50ms [ 167.022040] usb usb2-port2: not warm reset yet, waiting 200ms [ 167.276043] usb usb2-port2: status 02c0, change 0041, 5.0 Gb/s [ 167.276050] usb 2-2: USB disconnect, device number 2 [ 167.276058] usb 2-2: unregistering device [ 167.276060] usb 2-2: unregistering interface 2-2:1.0 [ 167.276170] xhci_hcd 0000:00:15.0: shutdown urb ffffa3c7cc695cc0 ep1in-bulk [ 167.284055] sd 0:0:0:0: [sda] tag#0 FAILED Result: hostbyte=DID_NO_CONNECT driverbyte=DRIVER_OK [ 167.284064] sd 0:0:0:0: [sda] tag#0 CDB: Read(10) 28 00 00 33 04 90 00 01 00 00 ... Analyzed the USB trace in the link layer we realized it is because of the 6-ms timer of tRecoveryConfigurationTimeout which documented on the USB 3.2 Revision 1.0, the section 7.5.10.4.2 of "Exit from Recovery.Configuration"; device initiates U1 exit -> Recovery.Active -> Recovery.Configuration, then the host timer timeout makes the link transits to eSS.Inactive -> Rx.Detect follows by a Warm Reset. Interestingly, the other higher volume of SanDisk Ultra Flair sharing the same VID:PID, such as 64GB, would not request LPM during runtime, it sticks at U0 always, thus disabling LPM does not affect those thumb drives at all. The same odd occures in SanDisk Ultra Fit 16GB, VID:PID in 0781:5583.

Realtek USB3.0 Card Reader [0bda:0328] reports wrong port status on Cannon lake PCH USB3.1 xHCI [8086:a36d] after resume from S3, after clear port reset it works fine. Since this device is registered on USB3 roothub at boot, when port status reports not superspeed, xhci_get_port_status will call an uninitialized completion in bus_state[0]. Kernel will hang because of NULL pointer. Restrict the USB2 resume status check in USB2 roothub to fix hang issue.

USB3 roothub might autosuspend before a plugged USB3 device is detected, causing USB3 device enumeration failure. USB3 devices don't show up as connected and enabled until USB3 link trainig completes. On a fast booting platform with a slow USB3 link training the link might reach the connected enabled state just as the bus is suspending. If this device is discovered first time by the xhci_bus_suspend() routine it will be put to U3 suspended state like the other ports which failed to suspend earlier. The hub thread will notice the connect change and resume the bus, moving the port back to U0 This U0 -> U3 -> U0 transition right after being connected seems to be too much for some devices, causing them to first go to SS.Inactive state, and finally end up stuck in a polling state with reset asserted Fix this by failing the bus suspend if a port has a connect change or is in a polling state in xhci_bus_suspend(). Don't do any port changes until all ports are checked, buffer all port changes and only write them in the end if suspend can proceed Cc: stable@vger.kernel.org Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This will clear the USB_PORT_FEAT_C_CONNECTION bit in case of a hub port reset only if a device is was attached to the hub port before resetting the hub port. Using a Lenovo T480s attached to the ultra dock it was not possible to detect some usb-c devices at the dock usb-c ports because the hub_port_reset code will clear the USB_PORT_FEAT_C_CONNECTION bit after the actual hub port reset. Using this device combo the USB_PORT_FEAT_C_CONNECTION bit was set between the actual hub port reset and the clear of the USB_PORT_FEAT_C_CONNECTION bit. This ends up with clearing the USB_PORT_FEAT_C_CONNECTION bit after the new device was attached such that it was not detected. This patch will not clear the USB_PORT_FEAT_C_CONNECTION bit if there is currently no device attached to the port before the hub port reset. This will avoid clearing the connection bit for new attached devices.

In case gadget speed changes (i.e from super speed plus to super speed) after driver unbind only upto super speed descriptor pointers get populated. Super speed plus desc still holds the stale (already freed) pointer. As a result next composition switch results into double free of super speed plus descriptor. Fix this issue by setting all descriptor pointers to NULL after freeing them in usb_free_all_descriptors(). Also clean up gsi_unbind() which is setting up descriptor pointers to NULL already.
