TPM2_CC_Create(0x153) and TPM2_CC_CreatePrimary (0x131) involve generation of crypto keys which can be a computationally intensive task. The timeout is set to 3min. Rather than increasing default timeout a new constant is added, to not stall for too long on regular commands failures. Signed-off-by: Tomas Winkler <redacted>
Why are you radically chaging the default timeout? The commit message does not tell anything about that change. Why couldn't we just have two timeouts: one default and one long that would be at least as long as the longest timeout defined in the spec? Then we would not have to ever update LAST_CC constant, we could actually remove it completely. /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
