[PATCH RFC] driver core: bus: Correct return value for storing bus attribute drivers_probe

by Zijun Hu

From: Zijun Hu <quic_zijuhu(a)quicinc.com> drivers_probe_store() regards bus_rescan_devices_helper()'s returned value 0 as success when find driver for a single device user specify that is wrong since the following 3 failed cases also return 0: (1) the device is dead (2) bus fails to match() the device with any its driver (3) bus fails to probe() the device with any its driver Fixed by only regarding successfully attaching the device to a driver as success.

[PATCH] usb: gadget: dummy_hcd: execute hrtimer callback in softirq context

by andrey.konovalov＠linux.dev

From: Andrey Konovalov <andreyknvl(a)gmail.com> Commit a7f3813e589f ("usb: gadget: dummy_hcd: Switch to hrtimer transfer scheduler") switched dummy_hcd to use hrtimer and made the timer's callback be executed in the hardirq context. With that change, __usb_hcd_giveback_urb now gets executed in the hardirq context, which causes problems for KCOV and KMSAN. One problem is that KCOV now is unable to collect coverage from the USB code that gets executed from the dummy_hcd's timer callback, as KCOV cannot collect coverage in the hardirq context. Another problem is that the dummy_hcd hrtimer might get triggered in the middle of a softirq with KCOV remote coverage collection enabled, and that causes a WARNING in KCOV, as reported by syzbot. (I sent a separate patch to shut down this WARNING, but that doesn't fix the other two issues.) Finally, KMSAN appears to ignore tracking memory copying operations that happen in the hardirq context, which causes false positive kernel-infoleaks, as reported by syzbot. Change the hrtimer in dummy_hcd to execute the callback in the softirq context.

If we wanted to keep the hardirq hrtimer, we would need teach KCOV to collect coverage in the hardirq context (or disable it, which would be unfortunate) and also fix whatever is wrong with KMSAN, but all that requires some work. --- drivers/usb/gadget/udc/dummy_hcd.c | 14 ++++++++------ 1 file changed, 8 insertions(+), 6 deletions(-) diff --git a/drivers/usb/gadget/udc/dummy_hcd.c b/drivers/usb/gadget/udc/dummy_hcd.c index f37b0d8386c1a..ff7bee78bcc49 100644 --- a/drivers/usb/gadget/udc/dummy_hcd.c +++ b/drivers/usb/gadget/udc/dummy_hcd.c @@ -1304,7 +1304,8 @@ static int dummy_urb_enqueue( /* kick the scheduler, it'll do the rest */ if (!hrtimer_active(&dum_hcd->timer)) - hrtimer_start(&dum_hcd->timer, ns_to_ktime(DUMMY_TIMER_INT_NSECS), HRTIMER_MODE_REL); + hrtimer_start(&dum_hcd->timer, ns_to_ktime(DUMMY_TIMER_INT_NSECS), + HRTIMER_MODE_REL_SOFT); done: spin_unlock_irqrestore(&dum_hcd->dum->lock, flags); @@ -1325,7 +1326,7 @@ static int dummy_urb_dequeue(struct usb_hcd *hcd, struct urb *urb, int status) rc = usb_hcd_check_unlink_urb(hcd, urb, status); if (!rc && dum_hcd->rh_state != DUMMY_RH_RUNNING && !list_empty(&dum_hcd->urbp_list)) - hrtimer_start(&dum_hcd->timer, ns_to_ktime(0), HRTIMER_MODE_REL); + hrtimer_start(&dum_hcd->timer, ns_to_ktime(0), HRTIMER_MODE_REL_SOFT); spin_unlock_irqrestore(&dum_hcd->dum->lock, flags); return rc; @@ -1995,7 +1996,8 @@ static enum hrtimer_restart dummy_timer(struct hrtimer *t) dum_hcd->udev = NULL; } else if (dum_hcd->rh_state == DUMMY_RH_RUNNING) { /* want a 1 msec delay here */ - hrtimer_start(&dum_hcd->timer, ns_to_ktime(DUMMY_TIMER_INT_NSECS), HRTIMER_MODE_REL); + hrtimer_start(&dum_hcd->timer, ns_to_ktime(DUMMY_TIMER_INT_NSECS), + HRTIMER_MODE_REL_SOFT); } spin_unlock_irqrestore(&dum->lock, flags); @@ -2389,7 +2391,7 @@ static int dummy_bus_resume(struct usb_hcd *hcd) dum_hcd->rh_state = DUMMY_RH_RUNNING; set_link_state(dum_hcd); if (!list_empty(&dum_hcd->urbp_list)) - hrtimer_start(&dum_hcd->timer, ns_to_ktime(0), HRTIMER_MODE_REL); + hrtimer_start(&dum_hcd->timer, ns_to_ktime(0), HRTIMER_MODE_REL_SOFT); hcd->state = HC_STATE_RUNNING; } spin_unlock_irq(&dum_hcd->dum->lock); @@ -2467,7 +2469,7 @@ static DEVICE_ATTR_RO(urbs); static int dummy_start_ss(struct dummy_hcd *dum_hcd) { - hrtimer_init(&dum_hcd->timer, CLOCK_MONOTONIC, HRTIMER_MODE_REL); + hrtimer_init(&dum_hcd->timer, CLOCK_MONOTONIC, HRTIMER_MODE_REL_SOFT); dum_hcd->timer.function = dummy_timer; dum_hcd->rh_state = DUMMY_RH_RUNNING; dum_hcd->stream_en_ep = 0; @@ -2497,7 +2499,7 @@ static int dummy_start(struct usb_hcd *hcd) return dummy_start_ss(dum_hcd); spin_lock_init(&dum_hcd->dum->lock); - hrtimer_init(&dum_hcd->timer, CLOCK_MONOTONIC, HRTIMER_MODE_REL); + hrtimer_init(&dum_hcd->timer, CLOCK_MONOTONIC, HRTIMER_MODE_REL_SOFT); dum_hcd->timer.function = dummy_timer; dum_hcd->rh_state = DUMMY_RH_RUNNING; -- 2.25.1

[PATCH] ASoC: rt5682: Return devm_of_clk_add_hw_provider to transfer the error

[PATCH v2] usb: xhci: fixes lost of data for xHCI Cadence Controllers

by Pawel Laszczak

Stream endpoint can skip part of TD during next transfer initialization after beginning stopped during active stream data transfer. The Set TR Dequeue Pointer command does not clear all internal transfer-related variables that position stream endpoint on transfer ring. USB Controller stores all endpoint state information within RsvdO fields inside endpoint context structure. For stream endpoints, all relevant information regarding particular StreamID is stored within corresponding Stream Endpoint context. Whenever driver wants to stop stream endpoint traffic, it invokes Stop Endpoint command which forces the controller to dump all endpoint state-related variables into RsvdO spaces into endpoint context and stream endpoint context. Whenever driver wants to reinitialize endpoint starting point on Transfer Ring, it uses the Set TR Dequeue Pointer command to update dequeue pointer for particular stream in Stream Endpoint Context. When stream endpoint is forced to stop active transfer in the middle of TD, it dumps an information about TRB bytes left in RsvdO fields in Stream Endpoint Context which will be used in next transfer initialization to designate starting point for XDMA. This field is not cleared during Set TR Dequeue Pointer command which causes XDMA to skip over transfer ring and leads to data loss on stream pipe. Patch fixes this by clearing out all RsvdO fields before initializing new transfer via that StreamID. Field Rsvd0 is reserved field, so patch should not have impact for other xHCI controllers.
