I am unlikely to be there, but I have a feature request / food for thought: Using a mandatory userspace daemon (e.g. trousers) for TPM access sucks. Might it be possible to teach the kernel to handle context save and restore and let multiple processes open the device at once? Then a daemon wouldn't be necessary. There would still be a need for some policy (e.g. who can clear the SRK), but that should be manageable. Maybe there should be two device nodes. /dev/tpm_unpriv would be fully virtualized for access by multiple processes, but it would only allow use of the key hierarchy and read access to PCRs. /dev/tpm_priv would allow NV access, PCR writes, SRK clears, etc. --Andy > > Please register your interest by filling out this doodle > http://doodle.com/q9ezcrivhqrktw6u > > I'm not sure if I can get any funding for the summit... but maybe I can > arrange something. > > > Also I'm trying to bring along some TPM samples from my employer if possible. > > > Thanks > Peter > > p.s.: experienced kernel developers welcome :) > _______________________________________________ > Ksummit-discuss mailing list > ksummit-disc...@lists.linuxfoundation.org > https://lists.linuxfoundation.org/mailman/listinfo/ksummit-discuss -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
