[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

[merged mm-hotfixes-stable] mm-memcontrol-respect-zswapwriteback-setting-from-parent-cg-too.patch removed from -mm tree

The quilt patch titled Subject: mm/memcontrol: respect zswap.writeback setting from parent cg too has been removed from the -mm tree. Its filename was mm-memcontrol-respect-zswapwriteback-setting-from-parent-cg-too.patch This patch was dropped because it was merged into the mm-hotfixes-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Mike Yuan <me(a)yhndnzj.com> Subject: mm/memcontrol: respect zswap.writeback setting from parent cg too Date: Fri, 23 Aug 2024 16:27:06 +0000 Currently, the behavior of zswap.writeback wrt. the cgroup hierarchy seems a bit odd. Unlike zswap.max, it doesn't honor the value from parent cgroups. This surfaced when people tried to globally disable zswap writeback, i.e. reserve physical swap space only for hibernation [1] - disabling zswap.writeback only for the root cgroup results in subcgroups with zswap.writeback=1 still performing writeback. The inconsistency became more noticeable after I introduced the MemoryZSwapWriteback= systemd unit setting [2] for controlling the knob. The patch assumed that the kernel would enforce the value of parent cgroups. It could probably be workarounded from systemd's side, by going up the slice unit tree and inheriting the value. Yet I think it's more sensible to make it behave consistently with zswap.max and friends.

[PATCH] x86/topology: Tolerate lack of APIC when booting as Xen domU

by Ariadne Conill

Xen domU instances do not boot on x86 with ACPI enabled, so the entire ACPI subsystem is ultimately disabled. This causes acpi_mps_check() to trigger a warning that the ACPI MPS table is not present, which then disables APIC support on domU, breaking the CPU topology detection for all vCPUs other than the boot vCPU.
