Subject: [PATCH] [FEAT VS2038] pvattest: Improve error reporting
From: Steffen Eiden <seiden@linux.ibm.com>

Summary:     pvattest: Create, perform, and verify attestation measurements
Description: pvattest is a tool to attest an IBM Secure Execution guest.
             
             In a trusted environment, one can create a request using
             `pvattest create`. To get a measurement of an untrusted
             IBM Secure Execution guest call 'pvattest perform'.
             Again in a trusted environment, call 'pvattest verify'
             to verify that the measurement is the expected one.
             
             The tool runs on s390 and x86.
             It has the same requirements like libpv and therefore
             requires openssl v1.1.1+, glib2.56+, and libcurl.
             Additionally, to measure, the linux kernel must provide
             the Ultravisor userspace interface `uvdevice` at /dev/uv
             and must be executed  on an IBM Secure Execution guest on
             hardware with Ultravisor attestation support,
             like IBM z16 or later.

Upstream-Description:

pvattest: Improve error reporting

Map the Ultravisor return code 0x2 to "Invalid UV command" string. This
             results in better error messages.
