2025-12-10x86/boot/Documentation: Fix htmldocs build warning due to malformed table in ↵Swaraj Gaikwad
boot.rst Sphinx reports htmldocs warnings: Documentation/arch/x86/boot.rst:437: ERROR: Malformed table. Text in column margin in table line 2. The table header defined the first column width as 2 characters ("=="), which is too narrow for entries like "0x10" and "0x13". This caused the text to spill into the margin, triggering a docutils parsing failure. Fix it by extending the first column of assigned boot loader ID to 4 characters ("====") to fit the widest entries.

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 ...

Pull nfsd updates from Chuck Lever: - Mike Snitzer's mechanism for disabling I/O caching introduced in v6.18 is extended to include using direct I/O. The goal is to further reduce the memory footprint consumed by NFS clients accessing large data sets via NFSD. - The NFSD community adopted a maintainer entry profile during this cycle. See Documentation/filesystems/nfs/nfsd-maintainer-entry-profile.rst - Work continues on hardening NFSD's implementation of the pNFS block layout type. This type enables pNFS clients to directly access the underlying block devices that contain an exported file system, reducing server overhead and increasing data throughput. - The remaining patches are clean-ups and minor optimizations. Many thanks to the contributors, reviewers, testers, and bug reporters who participated during the v6.19 NFSD development cycle. * tag 'nfsd-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux: (38 commits) NFSD: nfsd-io-modes: Separate lists NFSD: nfsd-io-modes: Wrap shell snippets in literal code blocks NFSD: Add toctree entry for NFSD IO modes docs NFSD: add Documentation/filesystems/nfs/nfsd-io-modes.rst NFSD: Implement NFSD_IO_DIRECT for NFS WRITE NFSD: Make FILE_SYNC WRITEs comply with spec NFSD: Add trace point for SCSI fencing operation.

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 ...
