Commit 207696b17f38 ("tpm: use a map for tpm2_calc_ordinal_duration()")
inadvertently reduced the timeout for TPM2 key creation commands
(`CREATE_PRIMARY`, `CREATE`, `CREATE_LOADED`) from 300 seconds to 30
seconds.
This causes intermittent timeout failures, with several failures observed
across hundreds of test runs on some Intel platforms using Infineon
SLB9670 and SLB9672 TPM modules. Restore the timeout to 300 seconds to
avoid spurious failures.
Is this a production case?
I'm not sure if there is anything to fix tbh. I mean it is
pretty much the same as "maintaining compatibility to OTT driver"
to addresses issues on undisclosed hardware.
Please correct me if I'm wrong. Otherwise, I'd carry out internal patch
to tweak this for pre-production hardware (presumably).
Hi Jarkko, this is indeed a production case. We discovered this issue during
validation testing for the sustaining release.
OK, it can be considered as a backwards compatibility issue then I
guess.
I applied the patch, thank you.
BR, Jarkko
Thanks Jarkko and you all for your kindly review and help.
