Merge tag 'tsm-for-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/devsec/tsmPull trusted security manager (TSM) updates from Dan Williams: - Add a general sysfs scheme for publishing "Measurement" values provided by the architecture's TEE Security Manager. Use it to publish TDX "Runtime Measurement Registers" ("RTMRs") that either maintain a hash of stored values (similar to a TPM PCR) or provide statically provisioned data. These measurements are validated by a relying party. - Reorganize the drivers/virt/coco/ directory for "host" and "guest" shared infrastructure. - Fix a configfs-tsm-report unregister bug - With CONFIG_TSM_MEASUREMENTS joining CONFIG_TSM_REPORTS and in anticipation of more shared "TSM" infrastructure arriving, rename the maintainer entry to "TRUSTED SECURITY MODULE (TSM) INFRASTRUCTURE".* tag 'tsm-for-6.16' of git://git.kernel.org/pub/scm/linux/kernel/git/devsec/tsm: tsm-mr: Fix init breakage after bin_attrs constification by scoping non-const pointers to init phase sample/tsm-mr: Fix missing static for sample_report virt: tdx-guest: Transition to scoped_cond_guard for mutex operations virt: tdx-guest: Refactor and streamline TDREPORT generation virt: tdx-guest: Expose TDX MRs as sysfs attributes x86/tdx: tdx_mcall_get_report0: Return -EBUSY on TDCALL_OPERAND_BUSY error x86/tdx: Add tdx_mcall_extend_rtmr() interface tsm-mr: Add tsm-mr sample code tsm-mr: Add TVM Measurement Register support configfs-tsm-report: Fix NULL dereference of tsm_ops coco/guest: Move shared guest CC infrastructure to drivers/virt/coco/guest/ configfs-tsm: Namespace TSM report symbols List of files: /linux/drivers/virt/coco/tdx-guest/Kconfig

Sun, 05 Nov 2023 02:58:13 +0100

Merge tag 'tsm-for-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/linuxPull unified attestation reporting from Dan Williams: "In an ideal world there would be a cross-vendor standard attestation report format for confidential guests along with a common device definition to act as the transport. In the real world the situation ended up with multiple platform vendors inventing their own attestation report formats with the SEV-SNP implementation being a first mover to define a custom sev-guest character device and corresponding ioctl(). Later, this configfs-tsm proposal intercepted an attempt to add a tdx-guest character device and a corresponding new ioctl(). It also anticipated ARM and RISC-V showing up with more chardevs and more ioctls(). The proposal takes for granted that Linux tolerates the vendor report format differentiation until a standard arrives. From talking with folks involved, it sounds like that standardization work is unlikely to resolve anytime soon. It also takes the position that kernfs ABIs are easier to maintain than ioctl(). The result is a shared configfs mechanism to return per-vendor report-blobs with the option to later support a standard when that arrives. Part of the goal here also is to get the community into the "uncomfortable, but beneficial to the long term maintainability of the kernel" state of talking to each other about their differentiation and opportunities to collaborate. Think of this like the device-driver equivalent of the common memory-management infrastructure for confidential-computing being built up in KVM. As for establishing an "upstream path for cross-vendor confidential-computing device driver infrastructure" this is something I want to discuss at Plumbers. At present, the multiple vendor proposals for assigning devices to confidential computing VMs likely needs a new dedicated repository and maintainer team, but that is a discussion for v6.8. For now, Greg and Thomas have acked this approach and this is passing is AMD, Intel, and Google tests. Summary: - Introduce configfs-tsm as a shared ABI for confidential computing attestation reports - Convert sev-guest to additionally support configfs-tsm alongside its vendor specific ioctl() - Added signed attestation report retrieval to the tdx-guest driver forgoing a new vendor specific ioctl() - Misc cleanups and a new __free() annotation for kvfree()"* tag 'tsm-for-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/djbw/linux: virt: tdx-guest: Add Quote generation support using TSM_REPORTS virt: sevguest: Add TSM_REPORTS support for SNP_GET_EXT_REPORT mm/slab: Add __free() support for kvfree virt: sevguest: Prep for kernel internal get_ext_report() configfs-tsm: Introduce a shared ABI for attestation reports virt: coco: Add a coco/Makefile and coco/Kconfig virt: sevguest: Fix passing a stack buffer as a scatterlist target List of files: /linux/drivers/virt/coco/tdx-guest/Kconfig
