at least, if the xHC halts on a particular TRB due to an error then
the DCS field in the Out Endpoint Context maintained by the hardware
is not updated with the current cycle state.

Using the quirk XHCI_EP_CTX_BROKEN_DCS and instead fetch the DCS bit
from the TRB that the xHC stopped on.

usb: musb: dsps: Fix the probe error path 2021-10-20T09:45:00+00:00 Miquel Raynal miquel.raynal@bootlin.com 2021-10-05T22:16:31+00:00 9d89e287116796bf987cc48f5c8632ef3048f8eb commit c2115b2b16421d93d4993f3fe4c520e91d6fe801 upstream. Commit 7c75bde329d7 ("usb: musb: musb_dsps: request_irq() after initializing musb") has inverted the calls to dsps_setup_optional_vbus_irq() and dsps_create_musb_pdev() without updating correctly the error path. dsps_create_musb_pdev() allocates and registers a new platform device which must be unregistered and freed with platform_device_unregister(), and this is missing upon dsps_setup_optional_vbus_irq() error. While on the master branch it seems not to trigger any issue, I observed a kernel crash because of a NULL pointer dereference with a v5.10.70 stable kernel where the patch mentioned above was backported. With this kernel version, -EPROBE_DEFER is returned the first time dsps_setup_optional_vbus_irq() is called which triggers the probe to error out without unregistering the platform device. Unfortunately, on the Beagle Bone Black Wireless, the platform device still living in the system is being used by the USB Ethernet gadget driver, which during the boot phase triggers the crash. My limited knowledge of the musb world prevents me to revert this commit which was sent to silence a robot warning which, as far as I understand, does not make sense. The goal of this patch was to prevent an IRQ to fire before the platform device being registered. I think this cannot ever happen due to the fact that enabling the interrupts is done by the ->enable() callback of the platform musb device, and this platform device must be already registered in order for the core or any other user to use this callback. Hence, I decided to fix the error path, which might prevent future errors on mainline kernels while also fixing older ones.

Commit 7c75bde329d7 ("usb: musb: musb_dsps: request_irq() after
initializing musb") has inverted the calls to
dsps_setup_optional_vbus_irq() and dsps_create_musb_pdev() without
updating correctly the error path. dsps_create_musb_pdev() allocates and
registers a new platform device which must be unregistered and freed
with platform_device_unregister(), and this is missing upon

While on the master branch it seems not to trigger any issue, I observed
a kernel crash because of a NULL pointer dereference with a v5.10.70
stable kernel where the patch mentioned above was backported. With this
kernel version, -EPROBE_DEFER is returned the first time
dsps_setup_optional_vbus_irq() is called which triggers the probe to
error out without unregistering the platform device. Unfortunately, on
the Beagle Bone Black Wireless, the platform device still living in the
system is being used by the USB Ethernet gadget driver, which during the

My limited knowledge of the musb world prevents me to revert this commit
which was sent to silence a robot warning which, as far as I understand,

xhci: Fix command ring pointer corruption while aborting a command 2021-10-20T09:45:00+00:00 Pavankumar Kondeti pkondeti@codeaurora.org 2021-10-08T09:25:46+00:00 dec944bb7079b37968cf69c8a438f91f15c4cc61 commit ff0e50d3564f33b7f4b35cadeabd951d66cfc570 upstream. The command ring pointer is located at [6:63] bits of the command ring control register (CRCR). All the control bits like command stop, abort are located at [0:3] bits. While aborting a command, we read the CRCR and set the abort bit and write to the CRCR. The read will always give command ring pointer as all zeros. So we essentially write only the control bits. Since we split the 64 bit write into two 32 bit writes, there is a possibility of xHC command ring stopped before the upper dword (all zeros) is written. If that happens, xHC updates the upper dword of its internal command ring pointer with all zeros. Next time, when the command ring is restarted, we see xHC memory access failures. Fix this issue by only writing to the lower dword of CRCR where all control bits are located.

commit 880de403777376e50bdf60def359fa50a722006f upstream.

Make sure to allocate resources before registering the tty device to
avoid having a racing open() and write() fail to enable rx or
dereference a NULL pointer when accessing the uninitialised fifo.
