Subject: [PATCH v1] tpm2: add longer timeout for verify signature command
Date: Mon, 10 May 2021 17:27:19 +0300 [thread overview]
Message-ID: <20210510142719.48153-2-amirmizi6@gmail.com> (raw)
In-Reply-To: <20210510142719.48153-1-amirmizi6@gmail.com>
From: Amir Mizinski <amirmizi6@gmail.com>
TPM2_CC_VERIFY_SIGNATURE(0x177) Current timeout does not apply to usage with
RSA 3070-bit keys.
Additional time may be required for usage with RSA 3070-bit keys. Therefore, the
timeout of TPM2_CC_VERIFY_SIGNATURE is set to 3 minutes (TPM_LONG_LONG).
