git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity Pull integrity subsystem updates from Mimi Zohar: "The few changes are all kexec related: - The MOK keys are loaded onto the .platform keyring in order to verify the kexec kernel image signature. However, the MOK keys should only be trusted when secure boot is enabled. Before loading the MOK keys onto the .platform keyring, make sure the system is booted in secure boot mode. - When carrying the IMA measurement list across kexec, limit dumping the measurement list to when dynamic debug or CONFIG_DEBUG is enabled. - kselftest: add kexec_file_load selftest support for PowerNV and other cleanup" * tag 'integrity-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/zohar/linux-integrity: selftests/kexec: Enable secureboot tests for PowerPC ima: silence measurement list hexdump during kexec selftests/kexec: update searching for the Kconfig selftest/kexec: fix "ignored null byte in input" warning integrity: Do not load MOK and MOKx when secure boot be disabled ima: Fix undefined arch_ima_get_secureboot() and co

git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux Pull gpio updates from Bartosz Golaszewski: "The gpio-sim module is back, this time without any changes to configfs. This results in a less elegant user-space interface but I never got any follow-up on the committable items and didn't want to delay this module for several more months. Other than that we have support for several new models and some support going away. We started working on converting GPIO drivers to using fwnode exclusively in order to limit references to OF symbols to gpiolib-of.c exclusively. We also have regular tweaks and improvements all over the place. Summary: - new testing module: gpio-sim that is scheduled to replace gpio-mockup - initial changes aiming at converting all GPIO drivers to using the fwnode interface and limiting any references to OF symbols to gpiolib-of.c - add support for Tegra234 and Tegra241 to gpio-tegra186 - add support for new models (SSD201 and SSD202D) to gpio-msc313 - add basic support for interrupts to gpio-aggregator - add support for AMDIF031 HID device to gpio-amdpt - drop support for unused platforms in gpio-xlp - cleanup leftovers from the removal of the legacy Samsung Exynos GPIO driver - use raw spinlocks in gpio-aspeed and gpio-aspeed-sgpio to make PREEMPT_RT happy - generalize the common 'ngpios' device property by reading it in the core gpiolib code so that we can remove duplicate reads from drivers - allow line names from device properties to override names set by drivers - code shrink in gpiod_add_lookup_table() - add new model to the DT bindings for gpio-vf610 - convert DT bindings for tegra devices to YAML - improvements to interrupt handling in gpio-rcar and gpio-rockchip - updates to intel drivers from Andy (details in the merge commit) - some minor tweaks, improvements and coding-style fixes all around the subsystem" * tag 'gpio-updates-for-v5.17' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: (59 commits) gpio: rcar: Propagate errors from devm_request_irq() gpio: rcar: Use platform_get_irq() to get the interrupt gpio: ts5500: Use platform_get_irq() to get the interrupt gpio: dwapb: Switch to use fwnode instead of of_node gpiolib: acpi: make fwnode take precedence in struct gpio_chip dt-bindings: gpio: samsung: drop unused bindings gpio: max3191x: Use bitmap_free() to free bitmap gpio: regmap: Switch to use fwnode instead of of_node gpio: tegra186: Add support for Tegra241 dt-bindings: gpio: Add Tegra241 support gpio: brcmstb: Use local variable to access OF node gpio: Remove unused local OF node pointers gpio: sim: add missing fwnode_handle_put() in gpio_sim_probe() gpio: msc313: Add support for SSD201 and SSD202D gpio: msc313: Code clean ups dt-bindings: gpio: msc313: Add offsets for ssd20xd dt-bindings: gpio: msc313: Add compatible for ssd20xd gpio: sim: fix uninitialized ret variable gpio: Propagate firmware node from a parent device gpio: Setup parent device and get rid of unnecessary of_node assignment ...

Frederic fixed both early December and the fixes were sitting in for-5.16-fixes which I forgot to push. They are here now. I'll forward them to stable after they land. - The scheduler hook reorganization has more implicatoins for workqueue code in that the hooks are now more strictly synchronized and thus the interacting operations can become more straight-forward.

2022-01-11select: Fix indefinitely sleeping task in poll_schedule_timeout()Jan Kara1-30/+33
A task can end up indefinitely sleeping in do_select() -> poll_schedule_timeout() when the following race happens: TASK1 (thread1) TASK2 TASK1 (thread2) do_select() setup poll_wqueues table with 'fd' write data to 'fd' pollwake() table->triggered = 1 closes 'fd' thread1 is waiting for poll_schedule_timeout() - sees table->triggered table->triggered = 0 return -EINTR loop back in do_select() But at this point when TASK1 loops back, the fdget() in the setup of poll_wqueues fails. So now so we never find 'fd' is ready for reading and sleep in poll_schedule_timeout() indefinitely. Treat an fd that got closed as a fd on which some event happened. This makes sure cannot block indefinitely in do_select(). Another option would be to return -EBADF in this case but that has a potential of subtly breaking applications that excercise this behavior and it happens to work for them. So returning fd as active seems like a safer choice.

2022-01-11gfs2: dump inode object for iopen glocksBob Peterson1-0/+1
Before this patch, glock dumps would not dump the gl_object for iopen glocks. This information can help us debug problems related to eviction: when AN iopen glock is blocked we can see the status of its underlying inode and its flags, etc. Signed-off-by: Bob Peterson <[email protected]> Signed-off-by: Andreas Gruenbacher <[email protected]>
2022-01-11parisc: Default to 16 CPUs on 32-bit kernelHelge Deller1-1/+2
Qemu currently supports up to 16 CPUs, so increase the default from 4 to 16. Bload-o-meter shows only an increase of 800 bytes with this change. Signed-off-by: Helge Deller <[email protected]>
2022-01-11sections: Fix __is_kernel() to include init rangesHelge Deller1-3/+7
With CONFIG_KALLSYMS_ALL=y, the function is_ksym_addr() is used to determine if a symbol is from inside the kernel range. For that the given symbol address is checked if it's inside the _stext to _end range. Although this is correct, some architectures (e.g. parisc) may have the init area before the _stext address and as such the check in is_ksym_addr() fails. By extending the range check to include the init section, __is_kernel() will now detect symbols in this range as well. This fixes an issue on parisc where addresses of kernel functions in init sections aren't resolved to their symbol names. Signed-off-by: Helge Deller <[email protected]>
