2022-10-04ACPI: APEI: do not add task_work to kernel thread to avoid memory leakShuai Xue1-1/+1
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.

Commit d60cd06331a3 ("PM: ACPI: reboot: Use S5 for reboot") caused Dell PowerEdge r440 hangs at reboot. 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 Rangel1-0/+15
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 <[email protected]> Signed-off-by: Rafael J.

2022-10-04i2c: acpi: Use ACPI wake capability bit to set wake_irqRaul E Rangel3-13/+37
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.

2022-10-04powerpc/64: Fix msr_check_and_set/clear MSR[EE] raceNicholas Piggin2-2/+26
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.

When CONFIG_ARM_UNWIND=y, unwind annotations have been added to the exception entry and save_trace() will repeatedly save the exception PC: [0x7f000090] hrtimer_hander+0x8/0x10 [hrtimer] [0x8019ec50] __hrtimer_run_queues+0x18c/0x394 [0x8019f760] hrtimer_run_queues+0xbc/0xd0 [0x8019def0] update_process_times+0x34/0x80 [0x801ad2a4] tick_periodic+0x48/0xd0 [0x801ad3dc] tick_handle_periodic+0x1c/0x7c [0x8010f2e0] twd_handler+0x30/0x40 [0x80177620] handle_percpu_devid_irq+0xa0/0x23c [0x801718d0] generic_handle_domain_irq+0x24/0x34 [0x80502d28] gic_handle_irq+0x74/0x88 [0x8085817c] generic_handle_arch_irq+0x58/0x78 [0x80100ba8] __irq_svc+0x88/0xc8 [0x80108114] arch_cpu_idle+0x38/0x3c [0x80108114] arch_cpu_idle+0x38/0x3c <==== duplicate saved exception PC [0x80861bf8] default_idle_call+0x38/0x130 [0x8015d5cc] do_idle+0x150/0x214 [0x8015d978] cpu_startup_entry+0x18/0x1c [0x808589c0] rest_init+0xd8/0xdc [0x80c00a44] arch_post_acpi_subsys_init+0x0/0x8 We can move the special handling of the exception PC in save_trace() to the unwind_frame() of the frame pointer unwinder.

2022-10-04ARM: 9233/1: stacktrace: Skip frame pointer boundary check for call_with_stack()Li Huafei2-7/+35
When using the frame pointer unwinder, it was found that the stack trace output of stack_trace_save() is incomplete if the stack contains call_with_stack(): [0x7f00002c] dump_stack_task+0x2c/0x90 [hrtimer] [0x7f0000a0] hrtimer_hander+0x10/0x18 [hrtimer] [0x801a67f0] __hrtimer_run_queues+0x1b0/0x3b4 [0x801a7350] hrtimer_run_queues+0xc4/0xd8 [0x801a597c] update_process_times+0x3c/0x88 [0x801b5a98] tick_periodic+0x50/0xd8 [0x801b5bf4] tick_handle_periodic+0x24/0x84 [0x8010ffc4] twd_handler+0x38/0x48 [0x8017d220] handle_percpu_devid_irq+0xa8/0x244 [0x80176e9c] generic_handle_domain_irq+0x2c/0x3c [0x8052e3a8] gic_handle_irq+0x7c/0x90 [0x808ab15c] generic_handle_arch_irq+0x60/0x80 [0x8051191c] call_with_stack+0x1c/0x20 For the frame pointer unwinder, unwind_frame() checks stackframe::fp by stackframe::sp. Since call_with_stack() switches the SP from one stack to another, stackframe::fp and stackframe: :sp will point to different stacks, so we can no longer check stackframe::fp by stackframe::sp. Skip checking stackframe::fp at this point to avoid this problem.

2022-10-04alpha: add full ioread64/iowrite64 implementationArnd Bergmann13-23/+175
The previous patch introduced ioread64/iowrite64 declarations, but this means we no longer get the io-64-nonatomic variant, and run into a long error when someone actually wants to use these: ERROR: modpost: "ioread64" [drivers/net/ethernet/freescale/enetc/fsl-enetc.ko] undefined! Add the (hopefully) correct implementation for each machine type, based on the 32-bit accessor. Since the 32-bit return type does not work for ioread64(), change the internal implementation to use the correct width consistently, but leave the external interface to match the asm-generic/iomap.h header that uses 32-bit or 64-bit return values.

This provides a generic interface for userspace programs to determine whether a file supports DIO, and if so with what alignment restrictions. Specifically, STATX_DIOALIGN works on block devices, and on regular files when their containing filesystem has implemented support. An interface like this has been requested for years, since the conditions for when DIO is supported in Linux have gotten increasingly complex over time. Today, DIO support and alignment requirements can be affected by various filesystem features such as multi-device support, data journalling, inline data, encryption, verity, compression, checkpoint disabling, log-structured mode, etc. Further complicating things, Linux v6.0 relaxed the traditional rule of DIO needing to be aligned to the block device's logical block size; now user buffers (but not file offsets) only need to be aligned to the DMA alignment. The approach of uplifting the XFS specific ioctl XFS_IOC_DIOINFO was discarded in favor of creating a clean new interface with statx().

Pull nfsd updates from Chuck Lever: "This release is mostly bug fixes, clean-ups, and optimizations. One notable set of fixes addresses a subtle buffer overflow issue that occurs if a small RPC Call message arrives in an oversized RPC record. This is only possible on a framed RPC transport such as TCP. Because NFSD shares the receive and send buffers in one set of pages, an oversized RPC record steals pages from the send buffer that will be used to construct the RPC Reply message. NFSD must not assume that a full-sized buffer is always available to it; otherwise, it will walk off the end of the send buffer while constructing its reply. In this release, we also introduce the ability for the server to wait a moment for clients to return delegations before it responds with NFS4ERR_DELAY. This saves a retransmit and a network round- trip when a delegation recall is needed. This work will be built upon in future releases. The NFS server adds another shrinker to its collection. Because courtesy clients can linger for quite some time, they might be freeable when the server host comes under memory pressure. A new shrinker has been added that releases courtesy client resources during low memory scenarios. Lastly, of note: the maximum number of operations per NFSv4 COMPOUND that NFSD can handle is increased from 16 to 50. There are NFSv4 client implementations that need more than 16 to successfully perform a mount operation that uses a pathname with many components" * tag 'nfsd-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux: (53 commits) nfsd: extra checks when freeing delegation stateids nfsd: make nfsd4_run_cb a bool return function nfsd: fix comments about spinlock handling with delegations nfsd: only fill out return pointer on success in nfsd4_lookup_stateid NFSD: fix use-after-free on source server when doing inter-server copy NFSD: Cap rsize_bop result based on send buffer size NFSD: Rename the fields in copy_stateid_t nfsd: use DEFINE_SHOW_ATTRIBUTE to define nfsd_file_cache_stats_fops nfsd: use DEFINE_SHOW_ATTRIBUTE to define nfsd_reply_cache_stats_fops nfsd: use DEFINE_SHOW_ATTRIBUTE to define client_info_fops nfsd: use DEFINE_SHOW_ATTRIBUTE to define export_features_fops and supported_enctypes_fops nfsd: use DEFINE_PROC_SHOW_ATTRIBUTE to define nfsd_proc_ops NFSD: Pack struct nfsd4_compoundres NFSD: Remove unused nfsd4_compoundargs::cachetype field NFSD: Remove "inline" directives on op_rsize_bop helpers NFSD: Clean up nfs4svc_encode_compoundres() SUNRPC: Fix typo in xdr_buf_subsegment's kdoc comment NFSD: Clean up WRITE arg decoders NFSD: Use xdr_inline_decode() to decode NFSv3 symlinks NFSD: Refactor common code out of dirlist helpers ...
