git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit Pull audit updates from Paul Moore: "Six audit patches for v6.1, most are pretty trivial, but a quick list of the highlights are below: - Only free the audit proctitle information on task exit. This allows us to cache the information and improve performance slightly. - Use the time_after() macro to do time comparisons instead of doing it directly and potentially causing ourselves problems when the timer wraps. - Convert an audit_context state comparison from a relative enum comparison, e.g. (x < y), to a not-equal comparison to ensure that we are not caught out at some unknown point in the future by an enum shuffle. - A handful of small cleanups such as tidying up comments and removing unused declarations" * tag 'audit-pr-20221003' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/audit: audit: remove selinux_audit_rule_update() declaration audit: use time_after to compare time audit: free audit_proctitle only on task exit audit: explicitly check audit_context->context enum value audit: audit_context pid unused, context enum comment fix audit: fix repeated words in comments

2022-10-04ceph: fail the open_by_handle_at() if the dentry is being unlinkedXiubo Li
When unlinking a file the kclient will send a unlink request to MDS by holding the dentry reference, and then the MDS will return 2 replies, which are unsafe reply and a deferred safe reply. After the unsafe reply received the kernel will return and succeed the unlink request to user space apps. Only when the safe reply received the dentry's reference will be released. Or the dentry will only be unhashed from dcache. But when the open_by_handle_at() begins to open the unlinked files it will succeed. The inode->i_count couldn't be used to check whether the inode is opened or not.

2022-10-04ceph: no need to wait for transition RDCACHE|RD -> RDXiubo Li
For write when trying to get the Fwb caps we need to keep waiting on transition from WRBUFFER|WR -> WR to avoid a new WR sync write from going before a prior buffered writeback happens. While for read there is no need to wait on transition from RDCACHE|RD -> RD, and we can just exclude the revoking caps and force to sync read.

2022-10-04xen-pcifront: Handle missed Connected stateJason Andryuk
An HVM guest with linux stubdomain and 2 PCI devices failed to start as libxl timed out waiting for the PCI devices to be added. It happens intermittently but with some regularity. libxl wrote the two xenstore entries for the devices, but then timed out waiting for backend state 4 (Connected) - the state stayed at 7 (Reconfiguring). (PCI passthrough to an HVM with stubdomain is PV passthrough to the stubdomain and then HVM passthrough with the QEMU inside the stubdomain.) The stubdomain kernel never printed "pcifront pci-0: Installing PCI frontend", so it seems to have missed state 4 which would have called pcifront_try_connect() -> pcifront_connect_and_init_dma() Have pcifront_detach_devices() special-case state Initialised and call pcifront_connect_and_init_dma(). Don't use pcifront_try_connect() because that sets the xenbus state which may throw off the backend. After connecting, skip the remainder of detach_devices since none have been initialized yet. When the backend switches to Reconfigured, pcifront_attach_devices() will pick them up again.

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.

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.

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.
