2023-04-20usb: typec: altmodes/displayport: Fix configure initial pin assignmentRD Babiera1-1/+5
commit eddebe39602efe631b83ff8d03f26eba12cfd760 upstream. While determining the initial pin assignment to be sent in the configure message, using the DP_PIN_ASSIGN_DP_ONLY_MASK mask causes the DFP_U to send both Pin Assignment C and E when both are supported by the DFP_U and UFP_U. The spec (Table 5-7 DFP_U Pin Assignment Selection Mandates, VESA DisplayPort Alt Mode Standard v2.0) indicates that the DFP_U never selects Pin Assignment E when Pin Assignment C is offered. Update the DP_PIN_ASSIGN_DP_ONLY_MASK conditional to intially select only Pin Assignment C if it is available.

2023-04-05usb: gadget: u_audio: don't let userspace block driver unbindAlvin Šipraga1-1/+1
commit 6c67ed9ad9b83e453e808f9b31a931a20a25629b upstream. In the unbind callback for f_uac1 and f_uac2, a call to snd_card_free() via g_audio_cleanup() will disconnect the card and then wait for all resources to be released, which happens when the refcount falls to zero. Since userspace can keep the refcount incremented by not closing the relevant file descriptor, the call to unbind may block indefinitely. This can cause a deadlock during reboot, as evidenced by the following blocked task observed on my machine: task:reboot state:D stack:0 pid:2827 ppid:569 flags:0x0000000c Call trace: __switch_to+0xc8/0x140 __schedule+0x2f0/0x7c0 schedule+0x60/0xd0 schedule_timeout+0x180/0x1d4 wait_for_completion+0x78/0x180 snd_card_free+0x90/0xa0 g_audio_cleanup+0x2c/0x64 afunc_unbind+0x28/0x60 ... kernel_restart+0x4c/0xac __do_sys_reboot+0xcc/0x1ec __arm64_sys_reboot+0x28/0x30 invoke_syscall+0x4c/0x110 ... The issue can also be observed by opening the card with arecord and then stopping the process through the shell before unbinding: # arecord -D hw:UAC2Gadget -f S32_LE -c 2 -r 48000 /dev/null Recording WAVE '/dev/null' : Signed 32 bit Little Endian, Rate 48000 Hz, Stereo ^Z[1]+ Stopped arecord -D hw:UAC2Gadget -f S32_LE -c 2 -r 48000 /dev/null # echo gadget.0 > /sys/bus/gadget/drivers/configfs-gadget/unbind (observe that the unbind command never finishes) Fix the problem by using snd_card_free_when_closed() instead, which will still disconnect the card as desired, but defer the task of freeing the resources to the core once userspace closes its file descriptor.

2023-03-03USB: core: Don't hold device lock while reading the "descriptors" sysfs fileAlan Stern2-8/+2
commit 45bf39f8df7f05efb83b302c65ae3b9bc92b7065 upstream. Ever since commit 83e83ecb79a8 ("usb: core: get config and string descriptors for unauthorized devices") was merged in 2013, there has been no mechanism for reallocating the rawdescriptors buffers in struct usb_device after the initial enumeration. Before that commit, the buffers would be deallocated when a device was deauthorized and reallocated when it was authorized and enumerated. This means that the locking in the read_descriptors() routine is not needed, since the buffers it reads will never be reallocated while the routine is running. This locking can interfere with user programs trying to read a hub's descriptors via sysfs while new child devices of the hub are being initialized, since the hub is locked during this procedure. Since the locking in read_descriptors() hasn't been needed for over nine years, we can remove it.

commit 54e5c00a4eb0a4c663445b245f641bbfab142430 upstream. While checking Pin Assignments of the port and partner during probe, we don't take into account whether the peripheral is a plug or receptacle. This manifests itself in a mode entry failure on certain docks and dongles with captive cables. For instance, the Startech.com Type-C to DP dongle (Model #CDP2DP) advertises its DP VDO as 0x405. This would fail the Pin Assignment compatibility check, despite it supporting Pin Assignment C as a UFP. Update the check to use the correct DP Pin Assign macros that take the peripheral's receptacle bit into account.

[ Upstream commit 6a19da111057f69214b97c62fb0ac59023970850 ] While performing fast composition switch, there is a possibility that the process of ffs_ep0_write/ffs_ep0_read get into a race condition due to ep0req being freed up from functionfs_unbind. Consider the scenario that the ffs_ep0_write calls the ffs_ep0_queue_wait by taking a lock &ffs->ev.waitq.lock. However, the functionfs_unbind isn't bounded so it can go ahead and mark the ep0req to NULL, and since there is no NULL check in ffs_ep0_queue_wait we will end up in use-after-free.

commit 7171b0e261b17de96490adf053b8bb4b00061bcf upstream. The Texas Instruments TUSB8041 has an autosuspend problem at high temperature. If there is not USB traffic, after a couple of ms, the device enters in autosuspend mode. In this condition the external clock stops working, to save energy. When the USB activity turns on, ther hub exits the autosuspend state, the clock starts running again and all works fine. At ambient temperature all works correctly, but at high temperature, when the USB activity turns on, the external clock doesn't restart and the hub disappears from the USB bus. Disabling the autosuspend mode for this hub solves the issue.

2023-01-24xhci: Detect lpm incapable xHC USB3 roothub ports from ACPI tablesMathias Nyman1-0/+34
commit 74622f0a81d0c2bcfc39f9192b788124e8c7f0af upstream. USB3 ports on xHC hosts may have retimers that cause too long exit latency to work with native USB3 U1/U2 link power management states. For now only use usb_acpi_port_lpm_incapable() to evaluate if port lpm should be disabled while setting up the USB3 roothub. Other ways to identify lpm incapable ports can be added here later if ACPI _DSM does not exist. Limit this to Intel hosts for now, this is to my knowledge only an Intel issue.

2023-01-24usb: acpi: add helper to check port lpm capability using acpi _DSMMathias Nyman1-0/+65
commit cd702d18c882d5a4ea44bbdb38edd5d5577ef640 upstream. Add a helper to evaluate ACPI usb device specific method (_DSM) provided in case the USB3 port shouldn't enter U1 and U2 link states. This _DSM was added as port specific retimer configuration may lead to exit latencies growing beyond U1/U2 exit limits, and OS needs a way to find which ports can't support U1/U2 link power management states. This _DSM is also used by windows: Link: https://docs.microsoft.com/en-us/windows-hardware/drivers/bringup/usb-device-specific-method---dsm- Some patch issues found in testing resolved by Ron Lee Cc: stable@vger.kernel.org Tested-by: Ron Lee <ron.lee@intel.com> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20230116142216.1141605-7-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2023-01-24xhci: Add a flag to disable USB3 lpm on a xhci root port level.Mathias Nyman2-0/+9
commit 0522b9a1653048440da5f21747f21e498b9220d1 upstream. One USB3 roothub port may support link power management, while another root port on the same xHC can't due to different retimers used for the ports. This is the case with Intel Alder Lake, and possible future platforms where retimers used for USB4 ports cause too long exit latecy to enable native USB3 lpm U1 and U2 states. Add a flag in the xhci port structure to indicate if the port is lpm_incapable, and check it while calculating exit latency.

2023-01-24xhci: Add update_hub_device override for PCI xHCI hostsMathias Nyman3-1/+17
commit 23a3b8d5a2365653fd9bc5a9454d1e7f4facbf85 upstream. Allow PCI hosts to check and tune roothub and port settings before the hub is up and running. This override is needed to turn off U1 and U2 LPM for some ports based on per port ACPI _DSM, _UPC, or possibly vendor specific mmio values for Intel xHC hosts. Usb core calls the host update_hub_device once it creates a hub. Entering U1 or U2 link power save state on ports with this limitation will cause link to fail, turning the usb device unusable in that setup.

Usb core may call xhci_free_dev() which frees the xhci->devs[slot_id] virt device at the same time that xhci_kill_endpoint_urbs() tries to loop through all the device's endpoints, checking if there are any cancelled urbs left to give back. hold the xhci spinlock while freeing the virt device Cc: stable@vger.kernel.org Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Link: https://lore.kernel.org/r/20230116142216.1141605-4-mathias.nyman@linux.intel.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

commit e8fb5bc76eb86437ab87002d4a36d6da02165654 upstream. When the host controller is not responding, all URBs queued to all endpoints need to be killed. This can cause a kernel panic if we dereference an invalid endpoint. Fix this by using xhci_get_virt_ep() helper to find the endpoint and checking if the endpoint is valid before dereferencing it.
