  "message": "tpm: Use HMAC-SHA256 library instead of open-coded HMAC\n\nNow that there are easy-to-use HMAC-SHA256 library functions, use these\nin tpm2-sessions.c instead of open-coding the HMAC algorithm.\n\nNote that the new implementation correctly handles keys longer than 64\nbytes (SHA256_BLOCK_SIZE), whereas the old implementation handled such\nkeys incorrectly.  But it doesn\u0027t appear that such keys were being used.\n\nSigned-off-by: Eric Biggers \u003cebiggers@kernel.org\u003e\nReviewed-by: Jarkko Sakkinen \u003cjarkko@kernel.org\u003e\nSigned-off-by: Jarkko Sakkinen \u003cjarkko@kernel.org\u003e\n",
