Merge tag 'tsm-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/devsec/tsmPull 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 It also turns out that all architectures, save for one, do not publish a mechanism for an OS to establish keys in the root port.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 ...

Tue, 02 Dec 2025 03:44:49 +0100

crypto/ccp: Implement SEV-TIO PCIe IDE (phase1)Implement the SEV-TIO (Trusted I/O) firmware interface for PCIe TDISP(Trust Domain In-Socket Protocol). This enables secure communicationbetween trusted domains and PCIe devices through the PSP (PlatformSecurity Processor).The implementation includes:- Device Security Manager (DSM) operations for establishing secure links- SPDM (Security Protocol and Data Model) over DOE (Data Object Exchange)- IDE (Integrity Data Encryption) stream management for secure PCIeThis module bridges the SEV firmware stack with the generic PCIe TSMframework.This is phase1 as described in Documentation/driver-api/pci/tsm.rst.On AMD SEV, the AMD PSP firmware acts as TSM (manages the security/trust).The CCP driver provides the interface to it and registers in the TSMsubsystem.Detect the PSP support (reported via FEATURE_INFO + SNP_PLATFORM_STATUS)and enable SEV-TIO in the SNP_INIT_EX call if the hardware supports TIO.Implement SEV TIO PSP command wrappers in sev-dev-tio.c and storethe data in the SEV-TIO-specific structs.Implement TSM hooks and IDE setup in sev-dev-tsm.c.Signed-off-by: Alexey Kardashevskiy Link: https://patch.msgid.link/692f506bb80c9_261c11004@dwillia2-mobl4.notmuchAcked-by: Tom Lendacky Signed-off-by: Dan Williams List of files: /linux/drivers/crypto/ccp/Kconfig
