Sun, 19 Apr 2026 00:13:09 +0200

smb: client: Remove obsolete cmac(aes) allocationSince the crypto library API is now being used instead of crypto_shash,the "cmac(aes)" crypto_shash that is being allocated and stored in'struct cifs_secmech' is no longer used. Remove it.That makes the kconfig selection of CRYPTO_CMAC and the module softdepon "cmac" unnecessary. So remove those too.Finally, since this removes the last use of crypto_shash from the smbclient, also remove the remaining crypto_shash-related helper functions.Note: cifs_unicode.c was relying on being includedtransitively via . Since the latter include isremoved, make cifs_unicode.c include explicitly.Reviewed-by: Ard Biesheuvel Signed-off-by: Eric Biggers Signed-off-by: Steve French List of files: /linux/fs/smb/client/Kconfig

3a4580e71371dc5d323ac1fb4af80316838aca14 - smb: client: Use AES-CMAC library for SMB3 signature calculation

Sun, 19 Apr 2026 00:13:08 +0200

smb: client: Use AES-CMAC library for SMB3 signature calculationConvert smb3_calc_signature() to use the AES-CMAC library instead of a"cmac(aes)" crypto_shash.The result is simpler and faster code. With the library there's no needto allocate memory, no need to handle errors except for key preparation,and the AES-CMAC code is accessed directly without inefficient indirectcalls and other unnecessary API overhead.For now a "cmac(aes)" crypto_shash is still being allocated in'struct cifs_secmech'. Later commits will remove that, simplifying thecode even further.Reviewed-by: Ard Biesheuvel Signed-off-by: Eric Biggers Signed-off-by: Steve French List of files: /linux/fs/smb/client/Kconfig

82f78acd5a9270370ef4aa3f032ede25f3dc91ee - Merge patch series "Add OP-TEE based RPMB driver for UFS devices"

Thu, 20 Nov 2025 16:26:13 +0100

Merge patch series "Add OP-TEE based RPMB driver for UFS devices"Bean Huo says:This patch series introduces OP-TEE based RPMB (Replay ProtectedMemory Block) support for UFS devices, extending the kernel-levelsecure storage capabilities that are currently available for eMMCdevices.Previously, OP-TEE required a userspace supplicant to access RPMBpartitions, which created complex dependencies and reliability issues,especially during early boot scenarios. Recent work by Linaro hasmoved core supplicant functionality directly into the Linux kernel foreMMC devices, eliminating userspace dependencies and enablingimmediate secure storage access. This series extends the same approachto UFS devices, which are used in enterprise and mobile applicationsthat require secure storage capabilities.Benefits: - Eliminates dependency on userspace supplicant for UFS RPMB access - Enables early boot secure storage access (e.g., fTPM, secure UEFI variables) - Provides kernel-level RPMB access as soon as UFS driver is initialized - Removes complex initramfs dependencies and boot ordering requirements - Ensures reliable and deterministic secure storage operations - Supports both built-in and modular fTPM configurations.Prerequisites:--------------This patch series depends on commit 7e8242405b94 ("rpmb: move structrpmb_frame to common header") which has been merged into mainlinev6.18-rc2.Link: https://patch.msgid.link/20251107230518.4060231-1-beanhuo@iokpp.deSigned-off-by: Martin K.
