To decrypt the dump of a PV guest, the comm-key (CCK) is required. Until now, no comm-key was provided to genprotimg, therefore decrypting the dump of a kvm-unit-test under PV was not possible. This patch makes sure that we create a random CCK if there's no $(TEST_DIR)/comm.key file. Also allow dumping of PV tests by passing the appropriate PCF to genprotimg (bit 34). --x-pcf is used to be compatible with older genprotimg versions, which don't support --enable-dump. 0xe0 is the default PCF value and only bit 34 is added. Unfortunately, recent versions of genprotimg removed the --x-comm-key argument which was used by older versions to specify the CCK. To support these versions, we need to parse the genprotimg help output and decide which argument to use. Signed-off-by: Nico Boehr <nrb@xxxxxxxxxxxxx>
