2022-10-05security/keys: Remove inconsistent __user annotationVincenzo Frascino
The declaration of keyring_read does not match the definition (security/keys/keyring.c). In this case the definition is correct because it matches what defined in "struct key_type::read" (linux/key-type.h). Fix the declaration removing the inconsistent __user annotation.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "Core: - Introduce and use a single page frag cache for allocating small skb heads, clawing back the 10-20% performance regression in UDP flood test from previous fixes. - Run packets which already went thru HW coalescing thru SW GRO. This significantly improves TCP segment coalescing and simplifies deployments as different workloads benefit from HW or SW GRO. - Shrink the size of the base zero-copy send structure. - Move TCP init under a new slow / sleepable version of DO_ONCE(). BPF: - Add BPF-specific, any-context-safe memory allocator. - Add helpers/kfuncs for PKCS#7 signature verification from BPF programs. - Define a new map type and related helpers for user space -> kernel communication over a ring buffer (BPF_MAP_TYPE_USER_RINGBUF). - Allow targeting BPF iterators to loop through resources of one task/thread. - Add ability to call selected destructive functions. Expose crash_kexec() to allow BPF to trigger a kernel dump. Use CAP_SYS_BOOT check on the loading process to judge permissions. - Enable BPF to collect custom hierarchical cgroup stats efficiently by integrating with the rstat framework. - Support struct arguments for trampoline based programs. Only structs with size <= 16B and x86 are supported. - Invoke cgroup/connect{4,6} programs for unprivileged ICMP ping sockets (instead of just TCP and UDP sockets). - Add a helper for accessing CLOCK_TAI for time sensitive network related programs. - Support accessing network tunnel metadata's flags. - Make TCP SYN ACK RTO tunable by BPF programs with TCP Fast Open. - Add support for writing to Netfilter's nf_conn:mark. Protocols: - WiFi: more Extremely High Throughput (EHT) and Multi-Link Operation (MLO) work (802.11be, WiFi 7). - vsock: improve support for SO_RCVLOWAT. - SMC: support SO_REUSEPORT. - Netlink: define and document how to use netlink in a "modern" way. Support reporting missing attributes via extended ACK. - IPSec: support collect metadata mode for xfrm interfaces. - TCPv6: send consistent autoflowlabel in SYN_RECV state and RST packets. - TCP: introduce optional per-netns connection hash table to allow better isolation between namespaces (opt-in, at the cost of memory and cache pressure). - MPTCP: support TCP_FASTOPEN_CONNECT. - Add NEXT-C-SID support in Segment Routing (SRv6) End behavior. - Adjust IP_UNICAST_IF sockopt behavior for connected UDP sockets. - Open vSwitch: - Allow specifying ifindex of new interfaces. - Allow conntrack and metering in non-initial user namespace. - TLS: support the Korean ARIA-GCM crypto algorithm. - Remove DECnet support. Driver API: - Allow selecting the conduit interface used by each port in DSA switches, at runtime. - Ethernet Power Sourcing Equipment and Power Device support. - Add tc-taprio support for queueMaxSDU parameter, i.e. setting per traffic class max frame size for time-based packet schedules. - Support PHY rate matching - adapting between differing host-side and link-side speeds. - Introduce QUSGMII PHY mode and 1000BASE-KX interface mode. - Validate OF (device tree) nodes for DSA shared ports; make phylink-related properties mandatory on DSA and CPU ports. Enforcing more uniformity should allow transitioning to phylink. - Require that flash component name used during update matches one of the components for which version is reported by info_get(). - Remove "weight" argument from driver-facing NAPI API as much as possible. It's one of those magic knobs which seemed like a good idea at the time but is too indirect to use in practice. - Support offload of TLS connections with 256 bit keys.

2022-10-04RISC-V: Increase range and default value of NR_CPUSAnup Patel
Currently, the range and default value of NR_CPUS is too restrictive for high-end RISC-V systems with large number of HARTs. The latest QEMU virt machine supports upto 512 CPUs so the current NR_CPUS is restrictive for QEMU as well. Other major architectures (such as ARM64, x86_64, MIPS, etc) have a much higher range and default value of NR_CPUS. This patch increases NR_CPUS range to 2-512 and default value to XLEN (i.e. 32 for RV32 and 64 for RV64).

2022-10-04x86/mm: Ease W^X enforcement back to just a warningDave Hansen
Currently, the "change_page_attr" (CPA) code refuses to create W+X mappings on 64-bit kernels. There have been reports both from 32-bit[1] and from BPF[2] users where this change kept the system from booting. These reports are showing up even after about a month of soak time in -next. To avoid breaking anything, never enforce W^X. Always warn and return the requested permissions even if a problem is detected. 1. https://lore.kernel.org/all/CAMj1kXHcF_iK_g0OZSkSv56Wmr=eQGQwNstcNjLEfS=mm7a06w@mail.gmail.com/ 2. https://lore.kernel.org/bpf/c84cc27c1a5031a003039748c3c099732a718aec.camel@kernel.org/T/#u Signed-off-by: Dave Hansen <dave.hansen@linux.intel.com> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: Borislav Petkov <bp@alien8.de> Cc: x86@kernel.org Cc: "H.

2022-10-04PM: Improve EXPORT_*_DEV_PM_OPS macrosPaul Cercueil
Update the _EXPORT_DEV_PM_OPS() internal macro. It was not used anywhere outside pm.h and pm_runtime.h, so it is safe to update it. Before, this macro would take a few parameters to be used as sleep and runtime callbacks. This made it unsuitable to use with different callbacks, for instance the "noirq" ones. It is now semantically different: instead of creating a conditionally exported dev_pm_ops structure, it only contains part of the definition. This macro should however never be used directly (hence the trailing underscore). Instead, the following four macros are provided: - EXPORT_DEV_PM_OPS(name) - EXPORT_GPL_DEV_PM_OPS(name) - EXPORT_NS_DEV_PM_OPS(name, ns) - EXPORT_NS_GPL_DEV_PM_OPS(name, ns) For instance, it is now possible to conditionally export noirq suspend/resume PM functions like this: EXPORT_GPL_DEV_PM_OPS(foo_pm_ops) = { NOIRQ_SYSTEM_SLEEP_PM_OPS(suspend_fn, resume_fn) }; The existing helper macros EXPORT_*_SIMPLE_DEV_PM_OPS() and EXPORT_*_RUNTIME_DEV_PM_OPS() have been updated to use these new macros.

2022-10-04ACPI: APEI: do not add task_work to kernel thread to avoid memory leakShuai Xue
If an error is detected as a result of user-space process accessing a corrupt memory location, the CPU may take an abort. Then the platform firmware reports kernel via NMI like notifications, e.g. NOTIFY_SEA, NOTIFY_SOFTWARE_DELEGATED, etc. For NMI like notifications, commit 7f17b4a121d0 ("ACPI: APEI: Kick the memory_failure() queue for synchronous errors") keep track of whether memory_failure() work was queued, and make task_work pending to flush out the queue so that the work is processed before return to user-space. The code use init_mm to check whether the error occurs in user space: if (current->mm != &init_mm) The condition is always true, becase _nobody_ ever has "init_mm" as a real VM any more. In addition to abort, errors can also be signaled as asynchronous exceptions, such as interrupt and SError. In such case, the interrupted current process could be any kind of thread. When a kernel thread is interrupted, the work ghes_kick_task_work deferred to task_work will never be processed because entry_handler returns to call ret_to_kernel() instead of ret_to_user(). Consequently, the estatus_node alloced from ghes_estatus_pool in ghes_in_nmi_queue_one_entry() will not be freed. After around 200 allocations in our platform, the ghes_estatus_pool will run of memory and ghes_in_nmi_queue_one_entry() returns ENOMEM. As a result, the event failed to be processed. sdei: event 805 on CPU 113 failed with error: -2 Finally, a lot of unhandled events may cause platform firmware to exceed some threshold and reboot. The condition should generally just do if (current->mm) as described in active_mm.rst documentation. Then if an asynchronous error is detected when a kernel thread is running, (e.g. when detected by a background scrubber), do not add task_work to it as the original patch intends to do.

The issue is fixed by commit 2ca1c94ce0b6 ("tg3: Disable tg3 device on system reboot to avoid triggering AER"), so use the new sysoff API to reinstate S5 for reboot on ACPI-based systems. Using S5 for reboot is default behavior under Windows: "A full shutdown (S5) occurs when a system restart is requested" [1].

2022-10-04ACPI: PM: Take wake IRQ into consideration when entering suspend-to-idleRaul E Rangel
This change adds support for ACPI devices that use ExclusiveAndWake or SharedAndWake in their _CRS GpioInt definition (instead of using _PRW), and also provide power resources. Previously the ACPI subsystem had no idea if the device had a wake capable interrupt armed. This resulted in the ACPI device PM system placing the device into D3Cold, and thus cutting power to the device. With this change we will now query the _S0W method to figure out the appropriate wake capable D-state. Signed-off-by: Raul E Rangel <rrangel@chromium.org> Signed-off-by: Rafael J.

2022-10-04i2c: acpi: Use ACPI wake capability bit to set wake_irqRaul E Rangel
Device tree already has a mechanism to pass the wake_irq. It does this by looking for the wakeup-source property and setting the I2C_CLIENT_WAKE flag. This CL adds the ACPI equivalent. It uses the ACPI interrupt wake flag to determine if the interrupt can be used to wake the system. Previously the i2c drivers had to make assumptions and blindly enable the wake IRQ. This can cause spurious wake events. e.g., If there is a device with an Active Low interrupt and the device gets powered off while suspending, the interrupt line will go low since it's no longer powered and wakes the system. For this reason we should respect the board designers wishes and honor the wake bit defined on the interrupt.

2022-10-04ACPI: resources: Add wake_capable parameter to acpi_dev_irq_flagsRaul E Rangel
ACPI IRQ/Interrupt resources contain a bit that describes if the interrupt should wake the system. This change exposes that bit via a new IORESOURCE_IRQ_WAKECAPABLE flag. Drivers should check this flag before arming an IRQ to wake the system.

2022-10-04gpiolib: acpi: Add wake_capable variants of acpi_dev_gpio_irq_getRaul E Rangel
The ACPI spec defines the SharedAndWake and ExclusiveAndWake share type keywords. This is an indication that the GPIO IRQ can also be used as a wake source. This change exposes the wake_capable bit so drivers can correctly enable wake functionality instead of making an assumption.

2022-10-04powerpc/64: Fix msr_check_and_set/clear MSR[EE] raceNicholas Piggin
irq soft-masking means that when Linux irqs are disabled, the MSR[EE] value can change from 1 to 0 asynchronously: if a masked interrupt of the PACA_IRQ_MUST_HARD_MASK variety fires while irqs are disabled, the masked handler will return with MSR[EE]=0. This means a sequence like mtmsr(mfmsr() | MSR_FP) is racy if it can be called with local irqs disabled, unless a hard_irq_disable has been done.
