[LU-5732] hsm: sanity check for sane progress extent value

• Type: Bug
• Resolution: Fixed
• Priority: Critical

Description

During an HSM archive or restore, the progress is reported by the copytool, in userspace. That value may be bogus. For
instance, this will crash the MDS in interval_set():

he.offset = -1;
he.length = 10;
rc = llapi_hsm_action_progress(hcp, &he, length, 0);

So check that userspace is giving a sane progress extent value.
