2025-12-08Merge tag 'clk-for-linus' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This is entirely SoC clk drivers. The majority diff wise is for the new Rockchip and Qualcomm clk drivers which is mostly lines and lines of data structures to describe the clk hardware in these SoCs. Beyond those two, Renesas continues to incrementally add clks to their SoC drivers, causing them to show up higher in the diffstat this time because they added quite a few clks all over the place. Overall it is a semi-quiet release that has some new clk drivers and the usual fixes for clock data that was wrong or missing and non-critical cleanups that plug error paths or fix typos.

2025-12-06ocfs2: fix xattr array entry __counted_by errorLinus Torvalds
Commit 2f26f58df041 ("ocfs2: annotate flexible array members with __counted_by_le()") started annotating the flexible arrays used by ocfs2, and now gcc complains about ocfs2_reflink_xattr_header(): In function ‘fortify_memset_chk’, inlined from ‘ocfs2_reflink_xattr_header’ at fs/ocfs2/xattr.c:6365:5: include/linux/fortify-string.h:480:25: error: call to ‘__write_overflow_field’ declared with attribute warning: detected write beyond size of field (1st parameter); maybe use struct_group()? [-Werror=attribute-warning] and it looks like the complaint is valid - even if the actual error message is somewhat confusing. The 'last' pointer points to past the end of the counted flex array, but is used as an actual 'last' entry rather than a 'one-past-last'. It looks like the code copied and cleared an extra entry (which is likely harmless in practice), but I don't know ocfs2 at all. Because it's also possible that the counted-by annotations are off-by-one, and so this needs checking by somebody who actually knows ocfs2. But in the meantime this fixes the build error, and certainly _looks_ sane.

Also preparation for LUO - "Live Update Orchestrator" (Pasha Tatashin) is a major new feature targeted at cloud environments. Quoting the cover letter: This series introduces the Live Update Orchestrator, a kernel subsystem designed to facilitate live kernel updates using a kexec-based reboot. This capability is critical for cloud environments, allowing hypervisors to be updated with minimal downtime for running virtual machines. LUO achieves this by preserving the state of selected resources, such as memory, devices and their dependencies, across the kernel transition. As a key feature, this series includes support for preserving memfd file descriptors, which allows critical in-memory data, such as guest RAM or any other large memory region, to be maintained in RAM across the kexec reboot. Mike Rappaport merits a mention here, for his extensive review and testing work. - "kexec: reorganize kexec and kdump sysfs" (Sourabh Jain) moves the kexec and kdump sysfs entries from /sys/kernel/ to /sys/kernel/kexec/ and adds back-compatibility symlinks which can hopefully be removed one day - "kho: fixes for vmalloc restoration" (Mike Rapoport) fixes a BUG which was being hit during KHO restoration of vmalloc() regions * tag 'mm-nonmm-stable-2025-12-06-11-14' of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm: (139 commits) calibrate: update header inclusion Reinstate "resource: avoid unnecessary lookups in find_next_iomem_res()" vmcoreinfo: track and log recoverable hardware errors kho: fix restoring of contiguous ranges of order-0 pages kho: kho_restore_vmalloc: fix initialization of pages array MAINTAINERS: TPM DEVICE DRIVER: update the W-tag init: replace simple_strtoul with kstrtoul to improve lpj_setup KHO: fix boot failure due to kmemleak access to non-PRESENT pages Documentation/ABI: new kexec and kdump sysfs interface Documentation/ABI: mark old kexec sysfs deprecated kexec: move sysfs entries to /sys/kernel/kexec test_kho: always print restore status kho: free chunks using free_page() instead of kfree() selftests/liveupdate: add kexec test for multiple and empty sessions selftests/liveupdate: add simple kexec-based selftest for LUO selftests/liveupdate: add userspace API selftests docs: add documentation for memfd preservation via LUO mm: memfd_luo: allow preserving memfd liveupdate: luo_file: add private argument to store runtime state mm: shmem: export some functions to internal.h ...

On file release, it checks if stop_count is set, and if so it decrements it. Since this code was originally written, the stop_count can be incremented by other use cases. This makes just checking the stop_count not enough to know if it should be decremented. Add a new iterator flag called "PAUSE" and have it set if the open disables tracing and only decrement the stop_count if that flag is set on close. - Remove length field in trace_seq_printf() of print_synth_event() When printing the synthetic event that has a static length array field, the vsprintf() of the trace_seq_printf() triggered a "(efault)" in the output. That's because the print_fmt replaced the "%.*s" with "%s" causing the arguments to be off. - Fix a bunch of typos * tag 'trace-v6.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: tracing: Fix typo in trace_seq.c tracing: Fix typo in trace_probe.c tracing: Fix multiple typos in trace_osnoise.c tracing: Fix multiple typos in trace_events_user.c tracing: Fix typo in trace_events_trigger.c tracing: Fix typo in trace_events_hist.c tracing: Fix typo in trace_events_filter.c tracing: Fix multiple typos in trace_events.c tracing: Fix multiple typos in trace.c tracing: Fix typo in ring_buffer_benchmark.c tracing: Fix multiple typos in ring_buffer.c tracing: Fix typo in fprobe.c tracing: Fix typo in fpgraph.c tracing: Fix fixed array of synthetic event tracing: Fix enabling of tracing on file release

git://git.kernel.org/pub/scm/linux/kernel/git/devsec/tsm Pull PCIe Link Encryption and Device Authentication from Dan Williams: "New PCI infrastructure and one architecture implementation for PCIe link encryption establishment via platform firmware services. This work is the result of multiple vendors coming to consensus on some core infrastructure (thanks Alexey, Yilun, and Aneesh!), and three vendor implementations, although only one is included in this pull. The PCI core changes have an ack from Bjorn, the crypto/ccp/ changes have an ack from Tom, and the iommu/amd/ changes have an ack from Joerg. PCIe link encryption is made possible by the soup of acronyms mentioned in the shortlog below. Link Integrity and Data Encryption (IDE) is a protocol for installing keys in the transmitter and receiver at each end of a link. That protocol is transported over Data Object Exchange (DOE) mailboxes using PCI configuration requests. The aspect that makes this a "platform firmware service" is that the key provisioning and protocol is coordinated through a Trusted Execution Envrionment (TEE) Security Manager (TSM). That is either firmware running in a coprocessor (AMD SEV-TIO), or quasi-hypervisor software (Intel TDX Connect / ARM CCA) running in a protected CPU mode. Now, the only reason to ask a TSM to run this protocol and install the keys rather than have a Linux driver do the same is so that later, a confidential VM can ask the TSM directly "can you certify this device?". That precludes host Linux from provisioning its own keys, because host Linux is outside the trust domain for the VM. It also turns out that all architectures, save for one, do not publish a mechanism for an OS to establish keys in the root port. So "TSM-established link encryption" is the only cross-architecture path for this capability for the foreseeable future. This unblocks the other arch implementations to follow in v6.20/v7.0, once they clear some other dependencies, and it unblocks the next phase of work to implement the end-to-end flow of confidential device assignment. The PCIe specification calls this end-to-end flow Trusted Execution Environment (TEE) Device Interface Security Protocol (TDISP). In the meantime, Linux gets a link encryption facility which has practical benefits along the same lines as memory encryption. It authenticates devices via certificates and may protect against interposer attacks trying to capture clear-text PCIe traffic. Summary: - Introduce the PCI/TSM core for the coordination of device authentication, link encryption and establishment (IDE), and later management of the device security operational states (TDISP). Notify the new TSM core layer of PCI device arrival and departure - Add a low level TSM driver for the link encryption establishment capabilities of the AMD SEV-TIO architecture - Add a library of helpers TSM drivers to use for IDE establishment and the DOE transport - Add skeleton support for 'bind' and 'guest_request' operations in support of TDISP" * tag 'tsm-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/devsec/tsm: (23 commits) crypto/ccp: Fix CONFIG_PCI=n build virt: Fix Kconfig warning when selecting TSM without VIRT_DRIVERS crypto/ccp: Implement SEV-TIO PCIe IDE (phase1) iommu/amd: Report SEV-TIO support psp-sev: Assign numbers to all status codes and add new ccp: Make snp_reclaim_pages and __sev_do_cmd_locked public PCI/TSM: Add 'dsm' and 'bound' attributes for dependent functions PCI/TSM: Add pci_tsm_guest_req() for managing TDIs PCI/TSM: Add pci_tsm_bind() helper for instantiating TDIs PCI/IDE: Initialize an ID for all IDE streams PCI/IDE: Add Address Association Register setup for downstream MMIO resource: Introduce resource_assigned() for discerning active resources PCI/TSM: Drop stub for pci_tsm_doe_transfer() drivers/virt: Drop VIRT_DRIVERS build dependency PCI/TSM: Report active IDE streams PCI/IDE: Report available IDE streams PCI/IDE: Add IDE establishment helpers PCI: Establish document for PCI host bridge sysfs attributes PCI: Add PCIe Device 3 Extended Capability enumeration PCI/TSM: Establish Secure Sessions and Link Encryption ...

2025-12-06sched/core: Fix psi_dequeue() for Proxy ExecutionJohn Stultz
Currently, if the sleep flag is set, psi_dequeue() doesn't change any of the psi_flags. This is because psi_task_switch() will clear TSK_ONCPU as well as other potential flags (TSK_RUNNING), and the assumption is that a voluntary sleep always consists of a task being dequeued followed shortly there after with a psi_sched_switch() call. Proxy Execution changes this expectation, as mutex-blocked tasks that would normally sleep stay on the runqueue. But in the case where the mutex-owning task goes to sleep, or the owner is on a remote cpu, we will then deactivate the blocked task shortly after. In that situation, the mutex-blocked task will have had its TSK_ONCPU cleared when it was switched off the cpu, but it will stay TSK_RUNNING. Then if we later dequeue it (as currently done if we hit a case find_proxy_task() can't yet handle, such as the case of the owner being on another rq or a sleeping owner) psi_dequeue() won't change any state (leaving it TSK_RUNNING), as it incorrectly expects a psi_task_switch() call to immediately follow. Later on when the task get woken/re-enqueued, and psi_flags are set for TSK_RUNNING, we hit an error as the task is already TSK_RUNNING: psi: inconsistent task state! task=188:kworker/28:0 cpu=28 psi_flags=4 clear=0 set=4 To resolve this, extend the logic in psi_dequeue() so that if the sleep flag is set, we also check if psi_flags have TSK_ONCPU set (meaning the psi_task_switch is imminent) before we do the shortcut return. If TSK_ONCPU is not set, that means we've already switched away, and this psi_dequeue call needs to clear the flags.

2025-12-06sched/fair: Fix unfairness caused by stalled tg_load_avg_contrib when the ↵xupengbo
last task migrates out When a task is migrated out, there is a probability that the tg->load_avg value will become abnormal. The reason is as follows: 1. Due to the 1ms update period limitation in update_tg_load_avg(), there is a possibility that the reduced load_avg is not updated to tg->load_avg when a task migrates out. 2. Even though __update_blocked_fair() traverses the leaf_cfs_rq_list and calls update_tg_load_avg() for cfs_rqs that are not fully decayed, the key function cfs_rq_is_decayed() does not check whether cfs->tg_load_avg_contrib is null.

2025-12-06sched/rt: Remove a preempt-disable section in rt_mutex_setprio()Sebastian Andrzej Siewior
rt_mutex_setprio() has only one caller: rt_mutex_adjust_prio(). It expects that task_struct::pi_lock and rt_mutex_base::wait_lock are held. Both locks are raw_spinlock_t and are acquired with disabled interrupts. Nevertheless rt_mutex_setprio() disables preemption while invoking __balance_callbacks() and raw_spin_rq_unlock(). Even if one of the balance callbacks unlocks the rq then it must not enable interrupts because rt_mutex_base::wait_lock is still locked. Therefore interrupts should remain disabled and disabling preemption is not needed. Commit 4c9a4bc89a9cc ("sched: Allow balance callbacks for check_class_changed()") adds a preempt-disable section to rt_mutex_setprio() and __sched_setscheduler(). In __sched_setscheduler() the preemption is disabled before rq is unlocked and interrupts enabled but I don't see why it makes a difference in rt_mutex_setprio(). Remove the preempt_disable() section from rt_mutex_setprio().

2025-12-06sched/hrtick: Fix hrtick() vs. scheduling contextPeter Zijlstra
The sched_class::task_tick() method is called on the donor sched_class, and sched_tick() hands it rq->donor as argument, which is consistent. However, while hrtick() uses the donor sched_class, it then passes rq->curr, which is inconsistent. Fix it.

2025-12-05nfs/localio: fix regression due to out-of-order __put_credMike Snitzer
Commit f2060bdc21d7 ("nfs/localio: add refcounting for each iocb IO associated with NFS pgio header") inadvertantly reintroduced the same potential for __put_cred() triggering BUG_ON(cred == current->cred) that commit 992203a1fba5 ("nfs/localio: restore creds before releasing pageio data") fixed. Fix this by saving and restoring the cred around each {read,write}_iter call within the respective for loop of nfs_local_call_{read,write} using scoped_with_creds(). NOTE: this fix started by first reverting the following commits: 94afb627dfc2 ("nfs: use credential guards in nfs_local_call_read()") bff3c841f7bd ("nfs: use credential guards in nfs_local_call_write()") 1d18101a644e ("Merge tag 'kernel-6.19-rc1.cred' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs") followed by narrowly fixing the cred lifetime issue by using scoped_with_creds(). In doing so, this commit's changes appear more extensive than they really are (as evidenced by comparing to v6.18's fs/nfs/localio.c).
