[Xen-devel] [PATCH v5 00/12] vTPM updates for 4.3

[Daniel De Graaf <dgdegra@xxxxxxxxxxxxx>]

This series contains a bit of reworking from v4: command cancellation is
now supported in the protocol, although not yet exposed through the API.
Since the TPM emulator used by Xen doesn't support cancellation anyway,
this is not currently an important requirement.

The xenbus name for the interface has been changed back to "vtpm" -
renaming it to vtpm2 requires changing libxl to only support the new
device name with mismatches between the use of vtpm in the API it
exposes and vtpm2 in the values used internally. Using feature nodes to
denote the protocol change allows also libxl to wire up both the old
interface and the new interface.

Automatic vTPM shutdown is removed by patch #9; however, since patch #8
makes it safe to destroy the vTPM at any point, the cleanup of a vTPM
upon guest shutdown can be relocated to the layer that starts the vTPM.
This is necessary even without these patches because vTPMs have never
automatically shut down if a guest encoutners an error in early boot or
simply does not load (or have) the frontend driver.

Locality-5 PCRs have been dropped since v4: this patch is not really
suited for upstreaming until there is a domain using the extra PCRs.
