This series cleans up tpm timeouts setting and handling. First motivation was to fix failures coming from too short timeouts for commands that creates keys. Key generation may take significant time depending on the underlying hardware. Rather than increasing default timeout a new constant is added, to not stall too long on regular commands failures. Second is to define timeouts for new tpm2 commands defined in TCG 1.36 spec.Probably a typo, since the latest TCG spec version is the 1.38 [0].quoted
Where can we get that specification? I don't have that new version and couldn't find it from the public internet. /Jarkko[0]: https://trustedcomputinggroup.org/tpm-library-specification/
I already have that version of the specifications but I thought that we were speaking about PC Client Platform spefication, which is at version 1.30. TCG spec is an ambiguous term so that is where the confusion started from. The only spec I've seen some timeouts is the PC Client Specification but I guess I've then missed the list in TPM 2.0 spefication. Where are they listed? I worked with Will Arthur durations based on PC Client Specification when TPM 2.0 support was first implemented. /Jarkko -- To unsubscribe from this list: send the line "unsubscribe linux-security-module" in the body of a message to majordomo at vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
