Tue, 14 Apr 2026 02:31:39 +0200

Merge tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linuxPull crypto library updates from Eric Biggers: - Migrate more hash algorithms from the traditional crypto subsystem to lib/crypto/ Like the algorithms migrated earlier (e.g. SHA-*), this simplifies the implementations, improves performance, enables further simplifications in calling code, and solves various other issues: - AES CBC-based MACs (AES-CMAC, AES-XCBC-MAC, and AES-CBC-MAC) - Support these algorithms in lib/crypto/ using the AES library and the existing arm64 assembly code - Reimplement the traditional crypto API's "cmac(aes)", "xcbc(aes)", and "cbcmac(aes)" on top of the library - Convert mac80211 to use the AES-CMAC library. Note: several other subsystems can use it too and will be converted later - Drop the broken, nonstandard, and likely unused support for "xcbc(aes)" with key lengths other than 128 bits - Enable optimizations by default - GHASH - Migrate the standalone GHASH code into lib/crypto/ - Integrate the GHASH code more closely with the very similar POLYVAL code, and improve the generic GHASH implementation to resist cache-timing attacks and use much less memory - Reimplement the AES-GCM library and the "gcm" crypto_aead template on top of the GHASH library. Remove "ghash" from the crypto_shash API, as it's no longer needed - Enable optimizations by default - SM3 - Migrate the kernel's existing SM3 code into lib/crypto/, and reimplement the traditional crypto API's "sm3" on top of it - I don't recommend using SM3, but this cleanup is worthwhile to organize the code the same way as other algorithms - Testing improvements: - Add a KUnit test suite for each of the new library APIs - Migrate the existing ChaCha20Poly1305 test to KUnit - Make the KUnit all_tests.config enable all crypto library tests - Move the test kconfig options to the Runtime Testing menu - Other updates to arch-optimized crypto code: - Optimize SHA-256 for Zhaoxin CPUs using the Padlock Hash Engine - Remove some MD5 implementations that are no longer worth keeping - Drop big endian and voluntary preemption support from the arm64 code, as those configurations are no longer supported on arm64 - Make jitterentropy and samples/tsm-mr use the crypto library APIs* tag 'libcrypto-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux: (66 commits) lib/crypto: arm64: Assume a little-endian kernel arm64: fpsimd: Remove obsolete cond_yield macro lib/crypto: arm64/sha3: Remove obsolete chunking logic lib/crypto: arm64/sha512: Remove obsolete chunking logic lib/crypto: arm64/sha256: Remove obsolete chunking logic lib/crypto: arm64/sha1: Remove obsolete chunking logic lib/crypto: arm64/poly1305: Remove obsolete chunking logic lib/crypto: arm64/gf128hash: Remove obsolete chunking logic lib/crypto: arm64/chacha: Remove obsolete chunking logic lib/crypto: arm64/aes: Remove obsolete chunking logic lib/crypto: Include instead of lib/crypto: aesgcm: Don't disable IRQs during AES block encryption lib/crypto: aescfb: Don't disable IRQs during AES block encryption lib/crypto: tests: Migrate ChaCha20Poly1305 self-test to KUnit lib/crypto: sparc: Drop optimized MD5 code lib/crypto: mips: Drop optimized MD5 code lib: Move crypto library tests to Runtime Testing menu crypto: sm3 - Remove 'struct sm3_state' crypto: sm3 - Remove the original "sm3_block_generic()" crypto: sm3 - Remove sm3_base.h ...

6bc9effb4cbf9b6eba0f51aba1c8893dfd4c8100 - coco/guest: Remove unneeded selection of CRYPTO

Thu, 04 Dec 2025 06:55:12 +0100

coco/guest: Remove unneeded selection of CRYPTOAll that's needed here is CRYPTO_HASH_INFO. It used to be the case thatCRYPTO_HASH_INFO was visible only when CRYPTO, but that was fixed bycommit aacb37f597d0 ("lib/crypto: hash_info: Move hash_info.c intolib/crypto/"). Now CRYPTO_HASH_INFO can be selected directly.Acked-by: Dan Williams Link: https://lore.kernel.org/r/20251204055512.494013-1-ebiggers@kernel.orgSigned-off-by: Eric Biggers List of files: /linux/drivers/virt/coco/guest/Kconfig

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/guest/Kconfig

7515f45c165269b72ee739e6fc26cc2ef928fc1b - coco/guest: Move shared guest CC infrastructure to drivers/virt/coco/guest/

Tue, 04 Mar 2025 08:14:26 +0100

coco/guest: Move shared guest CC infrastructure to drivers/virt/coco/guest/In preparation for creating a new drivers/virt/coco/host/ directory tohouse shared host driver infrastructure for confidential computing, moveconfigfs-tsm to a guest/ sub-directory. The tsm.ko module is renamed totsm_reports.ko. The old tsm.ko module was only ever demand loaded bykernel internal dependencies, so it should not affect existing userspacemodule install scripts.The new drivers/virt/coco/guest/ is also a preparatory landing spot fornew / optional TSM Report mechanics like a TCB stability enumeration /watchdog mechanism. To be added later.Cc: Wu Hao Cc: Yilun Xu Cc: Samuel Ortiz Cc: Tom Lendacky Reviewed-by: Alexey Kardashevskiy Reviewed-by: Kuppuswamy Sathyanarayanan Link: https://patch.msgid.link/174107246641.1288555.208426916259466774.stgit@dwillia2-xfh.jf.intel.comSigned-off-by: Dan Williams List of files: /linux/drivers/virt/coco/guest/Kconfig
