2022-12-12Merge tag 'printk-for-6.2' of ↵Linus Torvalds1-1/+1
git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux Pull printk updates from Petr Mladek: - Add NMI-safe SRCU reader API. It uses atomic_inc() instead of this_cpu_inc() on strong load-store architectures. - Introduce new console_list_lock to synchronize a manipulation of the list of registered consoles and their flags. This is a first step in removing the big-kernel-lock-like behavior of console_lock(). This semaphore still serializes console->write() calbacks against: - each other. It primary prevents potential races between early and proper console drivers using the same device. - suspend()/resume() callbacks and init() operations in some drivers. - various other operations in the tty/vt and framebufer susbsystems. It is likely that console_lock() serializes even operations that are not directly conflicting with the console->write() callbacks here. This is the most complicated big-kernel-lock aspect of the console_lock() that will be hard to untangle. - Introduce new console_srcu lock that is used to safely iterate and access the registered console drivers under SRCU read lock. This is a prerequisite for introducing atomic console drivers and console kthreads. It will reduce the complexity of serialization against normal consoles and console_lock(). Also it should remove the risk of deadlock during critical situations, like Oops or panic, when only atomic consoles are registered. - Check whether the console is registered instead of enabled on many locations. It was a historical leftover. - Cleanly force a preferred console in xenfb code instead of a dirty hack. - A lot of code and comment clean ups and improvements. * tag 'printk-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux: (47 commits) printk: htmldocs: add missing description tty: serial: sh-sci: use setup() callback for early console printk: relieve console_lock of list synchronization duties tty: serial: kgdboc: use console_list_lock to trap exit tty: serial: kgdboc: synchronize tty_find_polling_driver() and register_console() tty: serial: kgdboc: use console_list_lock for list traversal tty: serial: kgdboc: use srcu console list iterator proc: consoles: use console_list_lock for list iteration tty: tty_io: use console_list_lock for list synchronization printk, xen: fbfront: create/use safe function for forcing preferred netconsole: avoid CON_ENABLED misuse to track registration usb: early: xhci-dbc: use console_is_registered() tty: serial: xilinx_uartps: use console_is_registered() tty: serial: samsung_tty: use console_is_registered() tty: serial: pic32_uart: use console_is_registered() tty: serial: earlycon: use console_is_registered() tty: hvc: use console_is_registered() efi: earlycon: use console_is_registered() tty: nfcon: use console_is_registered() serial_core: replace uart_console_enabled() with uart_console_registered() ...

2022-12-05soc: fsl: qe: request pins non-exclusivelyDmitry Torokhov1-1/+1
Commit 84582f9ed090 ("soc: fsl: qe: Avoid using gpio_to_desc()") changed qe_pin_request() to request and hold GPIO corresponding to a given pin. Unfortunately this does not work, as fhci-hcd requests these GPIOs first, befor calling qe_pin_request() (see drivers/usb/host/fhci-hcd.c::of_fhci_probe()). To fix it change qe_pin_request() to request GPIOs non-exclusively, and free them once the code determines GPIO controller and offset for each GPIO/pin. Also reaching deep into gpiolib implementation is not the best idea. We should either export gpio_chip_hwgpio() or keep converting to the global gpio numbers space until we fix the driver to implement proper pin control.

2022-11-22usb: dwc3: gadget: Disable GUSB2PHYCFG.SUSPHY for End TransferThinh Nguyen1-1/+2
If there's a disconnection while operating in eSS, there may be a delay in VBUS drop response from the connector. In that case, the internal link state may drop to operate in usb2 speed while the controller thinks the VBUS is still high. The driver must make sure to disable GUSB2PHYCFG.SUSPHY when sending endpoint command while in usb2 speed. The End Transfer command may be called, and only that command needs to go through at this point. Let's keep it simple and unconditionally disable GUSB2PHYCFG.SUSPHY whenever we issue the command. This scenario is not seen in real hardware. In a rare case, our prototype type-c controller/interface may have a slow response triggerring this issue.

2022-11-09usb: add NO_LPM quirk for Realforce 87U KeyboardNicolas Dumazet1-0/+3
Before adding this quirk, this (mechanical keyboard) device would not be recognized, logging: new full-speed USB device number 56 using xhci_hcd unable to read config index 0 descriptor/start: -32 chopping to 0 config(s) It would take dozens of plugging/unpuggling cycles for the keyboard to be recognized. Keyboard seems to simply work after applying this quirk. This issue had been reported by users in two places already ([1], [2]) but nobody tried upstreaming a patch yet. After testing I believe their suggested fix (DELAY_INIT + NO_LPM + DEVICE_QUALIFIER) was probably a little overkill. I assume this particular combination was tested because it had been previously suggested in [3], but only NO_LPM seems sufficient for this device.

There is a deadlock in ci_otg_del_timer(), the process is shown below: (thread 1) | (thread 2) ci_otg_del_timer() | ci_otg_hrtimer_func() ... | spin_lock_irqsave() //(1) | ... ... | hrtimer_cancel() | spin_lock_irqsave() //(2) (block forever) We hold ci->lock in position (1) and use hrtimer_cancel() to wait ci_otg_hrtimer_func() to stop, but ci_otg_hrtimer_func() also need ci->lock in position (2). As a result, the hrtimer_cancel() in ci_otg_del_timer() will be blocked forever. This patch extracts hrtimer_cancel() from the protection of spin_lock_irqsave() in order that the ci_otg_hrtimer_func() could obtain the ci->lock. What`s more, there will be no race happen. Because the "next_timer" is always under the protection of spin_lock_irqsave() and we only check whether "next_timer" equals to NUM_OTG_FSM_TIMERS in the following code.

2022-11-08usb: typec: mux: Enter safe mode only when pins need to be reconfiguredRajat Khandelwal1-2/+13
There is no point to enter safe mode during DP/TBT configuration if the DP/TBT was already configured in mux. This is because safe mode is only applicable when there is a need to reconfigure the pins in order to avoid damage within/to port partner. In some chrome systems, IOM/mux is already configured before OS comes up. Thus, when driver is probed, it blindly enters safe mode due to PD negotiations but only after gfx driver lowers dp_phy_ownership, will the IOM complete safe mode and send an ack to PMC. Since, that never happens, we see IPC timeout. Hence, allow safe mode only when pin reconfiguration is not required, which makes sense.

2022-11-08Revert "usb: dwc3: disable USB core PHY management"Johan Hovold1-10/+0
This reverts commit 6000b8d900cd5f52fbcd0776d0cc396e88c8c2ea. The offending commit disabled the USB core PHY management as the dwc3 already manages the PHYs in question. Unfortunately some platforms have started relying on having USB core also controlling the PHY and this is specifically currently needed on some Exynos platforms for PHY calibration or connected device may fail to enumerate. The PHY calibration was previously handled in the dwc3 driver, but to work around some issues related to how the dwc3 driver interacts with xhci (e.g. using multiple drivers) this was moved to USB core by commits 34c7ed72f4f0 ("usb: core: phy: add support for PHY calibration") and a0a465569b45 ("usb: dwc3: remove generic PHY calibrate() calls"). The same PHY obviously should not be controlled from two different places, which for example do no agree on the PHY mode or power state during suspend, but as the offending patch was backported to stable, let's revert it for now.

2022-11-08USB: bcma: Make GPIO explicitly optionalLinus Walleij1-4/+6
What the code does is to not check the return value from devm_gpiod_get() and then avoid using an erroneous GPIO descriptor with IS_ERR_OR_NULL(). This will miss real errors from the GPIO core that should not be ignored, such as probe deferral. Instead request the GPIO as explicitly optional, which means that if it doesn't exist, the descriptor returned will be NULL. Then we can add error handling and also avoid just doing this on the device tree path, and simplify the site where the optional GPIO descriptor is used. There were some problems with cleaning up this GPIO descriptor use in the past, but this is the proper way to deal with it.

When servicing a transfer completion event, the dwc3 driver will reclaim TRBs of started requests up to the request associated with the interrupt event. Currently we don't check for interrupt due to missed isoc, and the driver may attempt to reclaim TRBs beyond the associated event. This causes invalid memory access when the hardware still owns the TRB. If there's a missed isoc TRB with IMI (interrupt on missed isoc), make sure to stop servicing further. Note that only the last TRB of chained TRBs has its status updated with missed isoc.

Endpoints are normally deleted from the bandwidth list when they are dropped, before the virt device is freed. If xHC host is dying or being removed then the endpoints aren't dropped cleanly due to functions returning early to avoid interacting with a non-accessible host controller.

Solves a list_del corruption kernel crash when unbinding xhci-pci, caused by xhci_mem_cleanup() when it later tried to delete already freed endpoints from the bandwidth list.

2022-10-25xhci-pci: Set runtime PM as default policy on all xHC 1.2 or later devicesMario Limonciello1-28/+4
For optimal power consumption of USB4 routers the XHCI PCIe endpoint used for tunneling must be in D3. Historically this is accomplished by a long list of PCIe IDs that correspond to these endpoints because the xhci_hcd driver will not default to allowing runtime PM for all devices. As both AMD and Intel have released new products with new XHCI controllers this list continues to grow. In reviewing the XHCI specification v1.2 on page 607 there is already a requirement that the PCI power management states D3hot and D3cold must be supported. In the quirk list, use this to indicate that runtime PM should be allowed on XHCI controllers.

Since commit fc274c1e9973 ("USB: gadget: Add a new bus for gadgets"), the gadget devices are proper driver core devices, which caused each device to request pinmux settings: aspeed_vhub 1e6a0000.usb-vhub: Initialized virtual hub in USB2 mode aspeed-g5-pinctrl 1e6e2080.pinctrl: pin A7 already requested by 1e6a0000.usb-vhub; cannot claim for gadget.0 aspeed-g5-pinctrl 1e6e2080.pinctrl: pin-232 (gadget.0) status -22 aspeed-g5-pinctrl 1e6e2080.pinctrl: could not request pin 232 (A7) from group USB2AD on device aspeed-g5-pinctrl g_mass_storage gadget.0: Error applying setting, reverse things back The vhub driver has already claimed the pins, so prevent the gadgets from requesting them too by setting the magic of_node_reused flag. This causes the driver core to skip the mux request.

2022-10-22usb: gadget: uvc: fix sg handling during video encodeJeff Vanhoof1-2/+2
In uvc_video_encode_isoc_sg, the uvc_request's sg list is incorrectly being populated leading to corrupt video being received by the remote end. When building the sg list the usage of buf->sg's 'dma_length' field is not correct and instead its 'length' field should be used.

2022-10-22usb: gadget: uvc: fix sg handling in error caseDan Vacura2-7/+19
If there is a transmission error the buffer will be returned too early, causing a memory fault as subsequent requests for that buffer are still queued up to be sent. Refactor the error handling to wait for the final request to come in before reporting back the buffer to userspace for all transfer types (bulk/isoc/isoc_sg). This ensures userspace knows if the frame was successfully sent.

With the re-use of the previous completion status in 0d1c407b1a749 ("usb: dwc3: gadget: Return proper request status") it could be possible that the next frame would also get dropped if the current frame has a missed isoc error. Ensure that an interrupt is requested for the start of a new frame.

2022-10-22usb: dwc3: gadget: Don't delay End Transfer on delayed_statusThinh Nguyen1-1/+11
The gadget driver may wait on the request completion when it sets the USB_GADGET_DELAYED_STATUS. Make sure that the End Transfer command can go through if the dwc->delayed_status is set so that the request can complete. When the delayed_status is set, the Setup packet is already processed, and the next phase should be either Data or Status. It's unlikely that the host would cancel the control transfer and send a new Setup packet during End Transfer command. But if that's the case, we can try again when ep0state returns to EP0_SETUP_PHASE.

git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm Pull MM updates from Andrew Morton: - Yu Zhao's Multi-Gen LRU patches are here. They've been under test in linux-next for a couple of months without, to my knowledge, any negative reports (or any positive ones, come to that). - Also the Maple Tree from Liam Howlett. An overlapping range-based tree for vmas. It it apparently slightly more efficient in its own right, but is mainly targeted at enabling work to reduce mmap_lock contention. Liam has identified a number of other tree users in the kernel which could be beneficially onverted to mapletrees. Yu Zhao has identified a hard-to-hit but "easy to fix" lockdep splat at [1]. This has yet to be addressed due to Liam's unfortunately timed vacation. He is now back and we'll get this fixed up. - Dmitry Vyukov introduces KMSAN: the Kernel Memory Sanitizer. It uses clang-generated instrumentation to detect used-unintialized bugs down to the single bit level. KMSAN keeps finding bugs. New ones, as well as the legacy ones. - Yang Shi adds a userspace mechanism (madvise) to induce a collapse of memory into THPs. - Zach O'Keefe has expanded Yang Shi's madvise(MADV_COLLAPSE) to support file/shmem-backed pages. - userfaultfd updates from Axel Rasmussen - zsmalloc cleanups from Alexey Romanov - cleanups from Miaohe Lin: vmscan, hugetlb_cgroup, hugetlb and memory-failure - Huang Ying adds enhancements to NUMA balancing memory tiering mode's page promotion, with a new way of detecting hot pages. - memcg updates from Shakeel Butt: charging optimizations and reduced memory consumption. - memcg cleanups from Kairui Song. - memcg fixes and cleanups from Johannes Weiner. - Vishal Moola provides more folio conversions - Zhang Yi removed ll_rw_block() :( - migration enhancements from Peter Xu - migration error-path bugfixes from Huang Ying - Aneesh Kumar added ability for a device driver to alter the memory tiering promotion paths. For optimizations by PMEM drivers, DRM drivers, etc. - vma merging improvements from Jakub Matěn. - NUMA hinting cleanups from David Hildenbrand. - xu xin added aditional userspace visibility into KSM merging activity. - THP & KSM code consolidation from Qi Zheng. - more folio work from Matthew Wilcox. - KASAN updates from Andrey Konovalov. - DAMON cleanups from Kaixu Xia. - DAMON work from SeongJae Park: fixes, cleanups. - hugetlb sysfs cleanups from Muchun Song. - Mike Kravetz fixes locking issues in hugetlbfs and in hugetlb core.
