This driver has a potential issue which this driver is possible to cause superfluous irqs after usb_pkt_pop() is called. So, after the commit 3af32605 ("usb: renesas_usbhs: fix error return code of usbhsf_pkt_handler()") had been applied, we could observe the following error happened when we used g_audio. renesas_usbhs e6590000.usb: irq_ready run_error 1 : -22 To fix the issue, disable the tx or rx interrupt in usb_pkt_pop(). Fixes: 2743e7f9 ("usb: renesas_usbhs: fix the usb_pkt_pop()") Cc: <stable@vger.kernel.org> # v4.4+ Signed-off-by:

Because of dwc2_hsotg_ep_stop_xfr() function uses poll mode, first need to mask GINTSTS_GOUTNAKEFF interrupt. In Slave mode GINTSTS_GOUTNAKEFF interrupt will be aserted only after pop OUT NAK status packet from RxFIFO. In dwc2_hsotg_ep_sethalt() function before setting DCTL_SGOUTNAK need to unmask GOUTNAKEFF interrupt. Tested by USBCV CH9 and MSC tests set in Slave, BDMA and DDMA. All tests are passed. Fixes: a4f82771 ("usb: dwc2: gadget: Disable enabled HW endpoint in dwc2_hsotg_ep_disable") Fixes: 6070636c ("usb: dwc2: Fix Stalling a Non-Isochronous OUT EP") Cc: stable <stable@vger.kernel.org> Signed-off-by:

When the dwc2 platform device is removed, it unregisters the generic phy. usb_remove_phy() is called and the dwc2 usb_phy is removed from the "phy_list", but the uevent may still attempt to get the usb_phy from the list, resulting in a page fault bug. Currently we can't access the usb_phy from the "phy_list" after the device is removed. As a fix check to make sure that we can get the usb_phy before moving forward with the uevent.

Commit a66d21d7 ("usb: xhci: Add support for Renesas controller with memory") added renesas_usb_fw.mem firmware reference to xhci-pci. Thus modinfo indicates xhci-pci.ko has "firmware: renesas_usb_fw.mem". But the firmware is only actually used with CONFIG_USB_XHCI_PCI_RENESAS. An unusable firmware reference can trigger safety checkers which look for drivers with unmet firmware dependencies. Avoid referring to renesas_usb_fw.mem in circumstances when it cannot be loaded (when CONFIG_USB_XHCI_PCI_RENESAS isn't set).

we found crash in dwc3_disconnect_gadget(), it is because dwc->gadget_driver become NULL before async access. 7dc0c55e ('USB: UDC core: Add udc_async_callbacks gadget op') suggest a common way to avoid such kind of issue. this change implment the callback in dwc3 and change related functions which have callback to usb gadget driver.

The MAX-3421 USB driver remembers the state of the USB toggles for a device/endpoint. To save SPI writes, this was only done when a new device/endpoint was being used. Unfortunately, if the old device was removed, this would cause writes to freed memory. To fix this, a simpler scheme is used. The toggles are read from hardware when a URB is completed, and the toggles are always written to hardware when any URB transaction is started. This will cause a few more SPI transactions, but no causes kernel panics. Fixes: 2d53139f ("Add support for using a MAX3421E chip as a host driver.")

During interrupt registration, attach state is checked. If attached, then the Type-C state is updated with typec_set_xxx functions and role switch is set with usb_role_switch_set_role(). If the usb_role_switch parameter is error or null, the function simply returns 0. So, to update usb_role_switch role if a device is attached before the irq is registered, usb_role_switch must be registered before irq registration.

When MSI is used by the ehci-hcd driver, it can cause lost interrupts which results in EHCI only continuing to work due to a polling fallback. But the reliance of polling drastically reduces performance of any I/O through EHCI. Interrupts are lost as the EHCI interrupt handler does not safely handle edge-triggered interrupts. It fails to ensure all interrupt status bits are cleared, which works with level-triggered interrupts but not the edge-triggered interrupts typical from using MSI. To fix this problem, check if the driver may have raced with the hardware setting additional interrupt status bits and clear status until it is in a stable state. Fixes: 306c54d0 ("usb: hcd: Try MSI interrupts on PCI devices") Tested-by:

The device initiated link power management U1/U2 states should not be enabled in case the system exit latency plus one bus interval (125us) is greater than the shortest service interval of any periodic endpoint. This is the case for both U1 and U2 sytstem exit latencies and link states. See USB 3.2 section 9.4.9 "Set Feature" for more details Note, before this patch the host and device initiated U1/U2 lpm states were both enabled with lpm. After this patch it's possible to end up with only host inititated U1/U2 lpm in case the exit latencies won't allow device initiated lpm. If this case we still want to set the udev->usb3_lpm_ux_enabled flag so that sysfs users can see the link may go to U1/U2. Signed-off-by:

Maximum Exit Latency (MEL) value is used by host to know how much in advance it needs to start waking up a U1/U2 suspended link in order to service a periodic transfer in time. Current MEL calculation only includes the time to wake up the path from U1/U2 to U0. This is called tMEL1 in USB 3.1 section C 1.5.2 Total MEL = tMEL1 + tMEL2 +tMEL3 + tMEL4 which should additinally include: - tMEL2 which is the time it takes for PING message to reach device - tMEL3 time for device to process the PING and submit a PING_RESPONSE - tMEL4 time for PING_RESPONSE to traverse back upstream to host. Add the missing tMEL2, tMEL3 and tMEL4 to MEL calculation. Cc: <stable@kernel.org> # v3.5 Signed-off-by:

There's a small window where a USB 2 remote wake may be left unhandled due to a race between hub thread and xhci port event interrupt handler. When the resume event is detected in the xhci interrupt handler it kicks the hub timer, which should move the port from resume to U0 once resume has been signalled for long enough. To keep the hub "thread" running we set a bus_state->resuming_ports flag. This flag makes sure hub timer function kicks itself. checking this flag was not properly protected by the spinlock. Flag was copied to a local variable before lock was taken. The local variable was then checked later with spinlock held. If interrupt is handled right after copying the flag to the local variable we end up stopping the hub thread before it can handle the USB 2 resume. CPU0 CPU1 (hub thread) (xhci event handler) xhci_hub_status_data() status = bus_state->resuming_ports; <Interrupt> handle_port_status() spin_lock() bus_state->resuming_ports = 1 set_flag(HCD_FLAG_POLL_RH) spin_unlock() spin_lock() if (!status) clear_flag(HCD_FLAG_POLL_RH) spin_unlock() Fix this by taking the lock a bit earlier so that it covers the resuming_ports flag copy in the hub thread Cc: <stable@vger.kernel.org> Signed-off-by:

When the user submits a control URB via usbfs, the user supplies the bRequestType value and the kernel uses it to compute the pipe value. However, do_proc_control() performs this computation incorrectly in the case where the bRequestType direction bit is set to USB_DIR_IN and the URB's transfer length is 0: The pipe's direction is also set to IN but it should be OUT, which is the direction the actual transfer will use regardless of bRequestType. Commit 5cc59c41 ("USB: core: WARN if pipe direction != setup packet direction") added a check to compare the direction bit in the pipe value to a control URB's actual direction and to WARN if they are different. This can be triggered by the incorrect computation mentioned above, as found by syzbot. This patch fixes the computation, thus avoiding the WARNing.

The kernel recovers in due course from missing Mlocked pages: but there was no point in calling page_mlock() (formerly known as try_to_munlock()) on a THP, because nothing got done even when it was found to be mapped in another VM_LOCKED vma. It's true that we need to be careful: Mlocked accounting of pte-mapped THPs is too difficult (so consistently avoided); but Mlocked accounting of only-pmd-mapped THPs is supposed to work, even when multiple mappings are mlocked and munlocked or munmapped. Refine the tests. There is already a VM_BUG_ON_PAGE(PageDoubleMap) in page_mlock(), so page_mlock_one() does not even have to worry about that complication. (I said the kernel recovers: but would page reclaim be likely to split THP before rediscovering that it's VM_LOCKED? I've not followed that up) Fixes: 9a73f61b ("thp, mlock: do not mlock PTE-mapped file huge pages") Signed-off-by:

Pull more s390 updates from Vasily Gorbik: - Fix preempt_count initialization. - Rework call_on_stack() macro to add proper type handling and avoid possible register corruption. - More error prone "register asm" removal and fixes. - Fix syscall restarting when multiple signals are coming in. This adds minimalistic trampolines to vdso so we can return from signal without using the stack which requires pgm check handler hacks when NX is enabled. - Remove HAVE_IRQ_EXIT_ON_IRQ_STACK since this is no longer true after switch to generic entry. - Fix protected virtualization secure storage access exception handling. - Make machine check C handler always enter with DAT enabled and move register validation to C code. - Fix tinyconfig boot problem by avoiding MONITOR CALL without CONFIG_BUG. - Increase asm symbols alignment to 16 to make it consistent with compilers. - Enable concurrent access to the CPU Measurement Counter Facility. - Add support for dynamic AP bus size limit and rework ap_dqap to deal with messages greater than recv buffer. * tag 's390-5.14-2' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linux: (41 commits) s390: preempt: Fix preempt_count initialization s390/linkage: increase asm symbols alignment to 16 s390: rename CALL_ON_STACK_NORETURN() to call_on_stack_noreturn() s390: add type checking to CALL_ON_STACK_NORETURN() macro s390: remove old CALL_ON_STACK() macro s390/softirq: use call_on_stack() macro s390/lib: use call_on_stack() macro s390/smp: use call_on_stack() macro s390/kexec: use call_on_stack() macro s390/irq: use call_on_stack() macro s390/mm: use call_on_stack() macro s390: introduce proper type handling call_on_stack() macro s390/irq: simplify on_async_stack() s390/irq: inline do_softirq_own_stack() s390/irq: simplify do_softirq_own_stack() s390/ap: get rid of register asm in ap_dqap() s390: rename PIF_SYSCALL_RESTART to PIF_EXECVE_PGSTE_RESTART s390: move restart of execve() syscall s390/signal: remove sigreturn on stack s390/signal: switch to using vdso for sigreturn and syscall restart ...
