Harald Arnesen reported [1] a deadlock at reboot time, and after he captured a stack trace a picture developed of what's going on: The distribution he's using is using iwd (not wpa_supplicant) to manage wireless. iwd will usually use the "socket owner" option when it creates new interfaces, so that they're automatically destroyed when it quits (unexpectedly or otherwise). This is also done by wpa_supplicant, but it doesn't do it for the normal one, only for additional ones, which is different with iwd. Anyway, during shutdown, iwd quits while the netdev is still UP, i.e. IFF_UP is set. This causes the stack trace that Linus so nicely transcribed from the pictures: cfg80211_destroy_iface_wk() takes wiphy_lock -> cfg80211_destroy_ifaces() ->ieee80211_del_iface ->ieeee80211_if_remove ->cfg80211_unregister_wdev ->unregister_netdevice_queue ->dev_close_many ->__dev_close_many ->raw_notifier_call_chain ->cfg80211_netdev_notifier_call and that last call tries to take wiphy_lock again. In commit a05829a7 ("cfg80211: avoid holding the RTNL when calling the driver") I had taken into account the possibility of recursing from cfg80211 into cfg80211_netdev_notifier_call() via the network stack, but only for NETDEV_UNREGISTER, not for what happens here, NETDEV_GOING_DOWN and NETDEV_DOWN notifications. Additionally, while this worked still back in commit 78f22b6a ("cfg80211: allow userspace to take ownership of interfaces"), it missed another corner case: unregistering a netdev will cause dev_close() to be called, and thus stop wireless operations (e.g. disconnecting), but there are some types of virtual interfaces in wifi that don't have a netdev - for that we need an additional call to cfg80211_leave(). So, to fix this mess, change cfg80211_destroy_ifaces() to not require the wiphy_lock(), but instead make it acquire it, but only after it has actually closed all the netdevs on the list, and then call cfg80211_leave() as well before removing them from the driver, to fix the second issue. The locking change in this requires modifying the nl80211 call to not get the wiphy lock passed in, but acquire it by itself after flushing any potentially pending destruction requests.

Pull spi updates from Mark Brown: "The only core work for SPI this time around is the completion of the conversion to the new style method for specifying transfer delays, meaning we can cope with what most controllers support more directly using conversions in the core rather than open coding in drivers. Otherwise it's a good stack of cleanups and fixes plus a few new drivers. Summary: - Completion of the conversion to new style transfer delay configuration - Introduction and use of module_parport_driver() helper, merged here as there's no parport tree - Support for Altera SoCs on DFL buses, NXP i.MX8DL, HiSilicon Kunpeng, MediaTek MT8195" * tag 'spi-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi: (113 commits) spi: Rename enable1 to activate in spi_set_cs() spi: Convert Freescale QSPI binding to json schema spi: stm32-qspi: fix debug format string spi: tools: make a symbolic link to the header file spi.h spi: fsi: add a missing of_node_put spi: Make error handling of gpiod_count() call cleaner spidev: Add Micron SPI NOR Authenta device compatible spi: brcm,spi-bcm-qspi: convert to the json-schema spi: altera: Add DFL bus driver for Altera API Controller spi: altera: separate core code from platform code spi: stm32-qspi: Fix compilation warning in ARM64 spi: Handle SPI device setup callback failure. spi: sync up initial chipselect state spi: stm32-qspi: Add dirmap support spi: stm32-qspi: Trigger DMA only if more than 4 bytes to transfer spi: stm32-qspi: fix pm_runtime usage_count counter spi: spi-zynqmp-gqspi: return -ENOMEM if dma_map_single fails spi: spi-zynqmp-gqspi: fix use-after-free in zynqmp_qspi_exec_op spi: spi-zynqmp-gqspi: Resolved slab-out-of-bounds bug spi: spi-zynqmp-gqspi: fix hang issue when suspend/resume ...

Pull hwmon updates from Guenter Roeck: "The most notable change is the removal of the amd_energy driver. It was rendered all but unusable by making its attributes privileged-only to work around a security issue. A suggested remedy was rejected by AMD, so the only real solution was to remove the driver. For the future, we'll have to make sure that no privileged-access-only drivers are accepted into the hwmon subsystem in the first place. The hwmon ABI document was updated accordingly. Other changes: PMBus drivers: - Added driver for MAX15301 - Added driver for BluTek BPA-RS600 - Added driver for fsp-3y PSUs and PDUs - Added driver for Infineon IR36021 - Added driver for ST STPDDC60 - Added support for TI TPS53676 to tps53679 driver - Introduced PMBUS symbol namespace. This was made necessary by a suggestion to use its exported functions from outside the hwmon subsystem. - Minor improvements and bug fixes New drivers: - Driver for NZXT Kraken X42/X52/X62/X72 Driver enhancements: - Added support for Intel D5005 to intel-m10-bmc-hwmon driver - Added support for NCT6686D to nct6683 driver Other: - Converted sch5627 and amd9240 drivers to hwmon_device_register_with_info() - Added support for fan drawers capability and present registers to mlxreg-fan driver - Added Dell Latitude E7440 to fan control whitelist in dell-smm driver - Replaced snprintf in show functions with sysfs_emit.

Pull ARM devicetree updates from Arnd Bergmann: "There are six new SoCs added this time. Apple M1 and Nuvoton WPCM450 have separate branches because they are new SoC families that require changes outside of device tree files. The other four are variations of already supported chips and get merged through this branch: - STMicroelectronics STM32H750 is one of many variants of STM32 microcontrollers based on the Cortex-M7 core. This is particularly notable since we rarely add support for new MMU-less chips these days. In this case, the board that gets added along with the platform is not a SoC reference platform but the "Art Pi" (https://art-pi.gitee.io/website/) machine that was originally design for the RT-Thread RTOS. - NXP i.MX8QuadMax is a variant of the growing i.MX8 embedded/industrial SoC family, using two Cortex-A72 and four Cortex-A53 cores. It gets added along with its reference board, the "NXP i.MX8QuadMax Multisensory Enablement Kit". - Qualcomm SC7280 is a Laptop SoC following the SC7180 (Snapdragon 7c) that is used in some Chromebooks and Windows laptops. Only a reference board is added for the moment. - TI AM64x Sita4ra is a new version of the K3 SoC family for industrial control, motor control, remote IO, IoT gateway etc., similar to the older AM65x family. Two reference machines are added alongside. Among the newly added machines, there is a very clear skew towards 64-bit machines now, with 12 32-bit machines compared to 23 64-bit machines.

Pull staging/IIO driver updates from Greg KH: "Here is the big set of staging and IIO driver updates for 5.13-rc1. Lots of little churn in here, and some larger churn as well. Major things are: - removal of wimax drivers, no one has this hardware anymore for this failed "experiment". - removal of the Google gasket driver, turns out no one wanted to maintain it or cares about it anymore, so they asked for it to be removed. - comedi finally moves out of the staging directory into drivers/comedi This is one of the oldest kernel subsystems around, being created in the 2.0 kernel days, and was one of the first things added to drivers/staging/ when that was created over 15 years ago. It should have been moved out of staging a long time ago, it's well maintained and used by loads of different devices in the real world every day. Nice to see this finally happen. - so many tiny coding style cleanups it's not funny. Perfect storm of at least 2 different intern project application deadlines combined to provide a huge number of new contributions in this area from people learning how to do kernel development. Great job to everyone involved here. There's also the normal updates for IIO drivers with new IIO drivers and updates all over that subsystem.

Pull x86 bus lock detection updates from Thomas Gleixner: "Support for enhanced split lock detection: Newer CPUs provide a second mechanism to detect operations with lock prefix which go accross a cache line boundary. Such operations have to take bus lock which causes a system wide performance degradation when these operations happen frequently. The new mechanism is not using the #AC exception. It triggers #DB and is restricted to operations in user space. Kernel side split lock access can only be detected by the #AC based variant. Contrary to the #AC based mechanism the #DB based variant triggers _after_ the instruction was executed. The mechanism is CPUID enumerated and contrary to the #AC version which is based on the magic TEST_CTRL_MSR and model/family based enumeration on the way to become architectural" * tag 'x86-splitlock-2021-04-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: Documentation/admin-guide: Change doc for split_lock_detect parameter x86/traps: Handle #DB for bus lock x86/cpufeatures: Enumerate #DB for bus lock detection

Pull entry code update from Thomas Gleixner: "Provide support for randomized stack offsets per syscall to make stack-based attacks harder which rely on the deterministic stack layout. The feature is based on the original idea of PaX's RANDSTACK feature, but uses a significantly different implementation. The offset does not affect the pt_regs location on the task stack as this was agreed on to be of dubious value. The offset is applied before the actual syscall is invoked. The offset is stored per cpu and the randomization happens at the end of the syscall which is less predictable than on syscall entry. The mechanism to apply the offset is via alloca(), i.e. abusing the dispised VLAs. This comes with the drawback that stack-clash-protection has to be disabled for the affected compilation units and there is also a negative interaction with stack-protector. Those downsides are traded with the advantage that this approach does not require any intrusive changes to the low level assembly entry code, does not affect the unwinder and the correct stack alignment is handled automatically by the compiler. The feature is guarded with a static branch which avoids the overhead when disabled. Currently this is supported for X86 and ARM64" * tag 'x86-entry-2021-04-26' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: arm64: entry: Enable random_kstack_offset support lkdtm: Add REPORT_STACK for checking stack offsets x86/entry: Enable random_kstack_offset support stack: Optionally randomize kernel stack offset each syscall init_on_alloc: Optimize static branches jump_label: Provide CONFIG-driven build state defaults
