Merge tag 'for-next-tpm-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmddPull TPM updates from Jarkko Sakkinen: "The bulk of this is Ross Philipson's TPM enablement for Trenchboot. That exposes TPM constants, and decouple and improve robustness of tpm_buf a bit in order to implement a minimal early TPM driver. Early boot code will call either SKINIT on AMD or GETSEC[SENTER] on Intel before jumping into kernel's entry point. They re-initalize TPM PCRs but leave up to the early boot code measure initrd, boot_params and Trenchboot associated metadata. The motivation here is just that we would want in future iterations of the series put our full focus to the x86 part of the review, and call it a day as per TPM changes. Further, even if Trenchboot turned out to be empty lottery the worst possible outcome for TPM driver is that things get cleaned up a bit"* tag 'for-next-tpm-7.3' of git://git.kernel.org/pub/scm/linux/kernel/git/jarkko/linux-tpmdd: tpm-buf: Add TPM buffer support header for standalone reuse tpm-buf: Memory-safe allocations tpm-buf: Remove chip parameter from tpm_buf_append_handle() tpm-buf: Merge TPM_BUF_BOUNDARY_ERROR and TPM_BUF_OVERFLOW tpm: Remove main TPM header from TPM event log header tpm: Move platform specific definitions to the new PTP header tpm: Move TPM common base definitions to the command header tpm: Move TPM2 specific definitions to the command header tpm: Move TPM1 specific definitions to the command header tpm: Initial step to reorganize TPM public headers tpm: st33zp24: Validate locality read result tpm: st33zp24: Return zero on status read failure tpm: tpm_tis_spi: fix nodef CR50 tpm_tis_spi_resume is null tpm: atmel: depend on X86 tpm: Remove redundant dev_err() tpm: tpm_i2c_nuvoton: disable IRQ on wait timeout List of files: /linux/drivers/char/tpm/Kconfig

TCG_ATMEL nevertheless dependsonly on HAS_IOPORT_MAP/HAS_IOPORT, which arm and arm64 also satisfy.There the probe is useless, and on platforms whose unbacked I/O accessfaults it oopses in init_atmel() at boot (e.g. arm/versatile): Unable to handle kernel paging request at virtual address fee0004e PC is at init_atmel+0x34/0x244TCG_NSC and TCG_TIS already "depends on X86" (commit 2f592f2a7d74 ("TPM:NSC and TIS drivers X86 dependency fix")); TCG_ATMEL was missed.

2c2615c8423890b5ef8e0a186b65607ef5fdeda1 - tpm: Compare HMAC values in constant time

Fri, 01 Aug 2025 23:24:21 +0200

tpm: Compare HMAC values in constant timeIn tpm_buf_check_hmac_response(), compare the HMAC values in constanttime using crypto_memneq() instead of in variable time using memcmp().This is worthwhile to follow best practices and to be consistent withMAC comparisons elsewhere in the kernel. However, in this driver theside channel seems to have been benign: the HMAC input data isguaranteed to always be unique, which makes the usual MAC forgery viatiming side channel not possible. Specifically, the HMAC input data intpm_buf_check_hmac_response() includes the "our_nonce" field, which wasgenerated by the kernel earlier, remains under the control of thekernel, and is unique for each call to tpm_buf_check_hmac_response().Signed-off-by: Eric Biggers Signed-off-by: Jarkko Sakkinen List of files: /linux/drivers/char/tpm/Kconfig
