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

4bddf4587c131d7b8ce8952cd32b284dcda0dd1f - tpm: Disable TPM2_TCG_HMAC by default

Mon, 25 Aug 2025 22:32:23 +0200

tpm: Disable TPM2_TCG_HMAC by defaultAfter reading all the feedback, right now disabling the TPM2_TCG_HMACis the right call.Other views discussed:A. Having a kernel command-line parameter or refining the feature otherwise. This goes to the area of improvements. E.g., one example is my own idea where the null key specific code would be replaced with a persistent handle parameter (which can be *unambigously* defined as part of attestation process when done correctly).B. Removing the code. I don't buy this because that is same as saying that HMAC encryption cannot work at all (if really nitpicking) in any form. Also I disagree on the view that the feature could not be refined to something more reasoable.Also, both A and B are worst options in terms of backporting.Thuss, this is the best possible choice.Cc: stable@vger.kernel.or # v6.10+Fixes: d2add27cf2b8 ("tpm: Add NULL primary creation")Suggested-by: Chris Fenner Signed-off-by: Jarkko Sakkinen List of files: /linux/drivers/char/tpm/Kconfig

Merge tag 'mfd-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfdPull MFD updates from Lee Jones: "This round of updates contains a fair amount of new device support, a couple of fixes and some refactoring. The most notable additions include new drivers for Loongson's Security Engine, RNG and TPM, new drivers for TI's TPS6594 Power Button and BQ257xx Charger ICs. The rest of the set provides a return value check fix and a refactoring to use a more modern GPIO API for the VEXPRESS sysreg driver, the removal of a deprecated IRQ ACK function from the MC13xxx RTC driver and a new DT binding for the aforementioned TI BQ257xx charger. New Support & Features: - Add a suite of drivers for the Loongson Security Engine, including the core controller, a Random Number Generator (RNG) and Trusted Platform Module (TPM) support. - Introduce support for the TI TPS6594 PMIC's power button, including the input driver, MFD cell registration, and a system power-off handler. - Add comprehensive support for the TI BQ257xx series of charger ICs, including the core MFD driver and a power supply driver for the charger functionality. Improvements & Fixes: - Check the return value of devm_gpiochip_add_data() in the VEXPRESS sysreg driver to prevent potential silent failures. Cleanups & Refactoring: - Add a MAINTAINERS entry for the new Loongson Security Engine drivers. - Convert the VEXPRESS sysreg driver to use the modern generic GPIO chip API. Removals: - Remove the deprecated and unused mc13xxx_irq_ack() function from the MC13xxx RTC, input and touchscreen drivers. Device Tree Bindings Updates: - Add device tree bindings for the TI BQ25703A charger"* tag 'mfd-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd: (69 commits) mfd: simple-mfd-i2c: Add compatible string for LX2160ARDB mfd: simple-mfd-i2c: Keep compatible strings in alphabetical order dt-bindings: mfd: twl: Add missing sub-nodes for TWL4030 & TWL603x dt-bindings: watchdog: Add SMARC-sAM67 support dt-bindings: mfd: tps6594: Allow gpio-line-names mfd: intel-lpss: Add Intel Wildcat Lake LPSS PCI IDs mfd: 88pm886: Add GPADC cell mfd: vexpress-sysreg: Use more common syntax for compound literals mfd: rz-mtu3: Fix MTU5 NFCR register offset mfd: max77705: Setup the core driver as an interrupt controller mfd: cs42l43: Remove IRQ masking in suspend mfd: cs42l43: Move IRQ enable/disable to encompass force suspend mfd: ls2kbmc: Add Loongson-2K BMC reset function support mfd: ls2kbmc: Introduce Loongson-2K BMC core driver mfd: bd71828, bd71815: Prepare for power-supply support dt-bindings: mfd: aspeed: Add AST2700 SCU compatibles dt-bindings: mfd: Convert aspeed,ast2400-p2a-ctrl to DT schema dt-bindings: mfd: fsl,mc13xxx: Add buttons node dt-bindings: mfd: fsl,mc13xxx: Convert txt to DT schema mfd: macsmc: Add "apple,t8103-smc" compatible ...

tpm: Add a driver for Loongson TPM deviceLoongson Security Engine supports random number generation, hash,symmetric encryption and asymmetric encryption. Based on theseencryption functions, TPM2 have been implemented in the LoongsonSecurity Engine firmware. This driver is responsible for copying datainto the memory visible to the firmware and receiving data from thefirmware.Co-developed-by: Yinggang Gu Signed-off-by: Yinggang Gu Signed-off-by: Qunqin Zhao Reviewed-by: Huacai Chen Reviewed-by: Jarkko Sakkinen Link: https://lore.kernel.org/r/20250705072045.1067-4-zhaoqunqin@loongson.cnSigned-off-by: Lee Jones List of files: /linux/drivers/char/tpm/Kconfig
