Some distros in Travis CI (e.g. Debian and Ubuntu) have problems with
downloading from sourceforge.net due unknown certificate issuer:

Running the "boot_aggregate" test without a physical TPM, requires
installing and initializing a software TPM. For now, use the same
method of initializing the TPM, based on the IBM tss, for both the
IBM and Intel's tss.
Build both the IBM and INTEL's tss.

Verifying the "boot_aggregate" requires reading the TPM PCRs for each of
the TPM banks. In test environments without a physical TPM, a software
TPM may be used, but requires initializing the TPM PCRs. By walking and
replaying the TPM event log, a software TPM may be properly initialized.

boot_aggregate test make use of a software TPM 2.0 in case it doesn't find
any /dev/tpm0 in the system or if the test is ran as a normal user. However,
when the system has a discrete TPM 1.2 and the user runs the test with a
non-root user evmctl fails to return the software TPM 2.0 boot aggregate
value because it tries to access TPM 1.2 the sysfs PCRs file and,
consequently, the test fails. Thus TPM 2.0 log test is not supported on
systems with a discrete TPM 1.2

display_pcrs() should include PCRS 8 - 9 as they are non-zeros on some
systems. boot_aggregate may span PCRs 0 - 9 so check()'s info message

For each kexec, an additional "boot_aggregate" will appear in the
measurement list, assuming the previous measurement list is carried
across kexec.
Verify that the last "boot_aggregate" record in the IMA measurement list
matches. The "boot_aggregate" is either the last field (e.g. "ima-ng")
or the second to last field (e.g. "ima-sig") in the measurement list
record.

Calculate the boot_aggregate for each TPM bank and verify that the
boot_aggregate in the IMA measurement list matches one of them.
A software TPM may be used to verify the boot_aggregate. If a
software TPM is not already running on the system, this test
starts one and initializes the TPM PCR banks by walking the sample
binary_bios_measurements event log, included in this directory, and
extending the TPM PCRs. The associated ascii_runtime_measurements
for verifying the calculated boot_aggregate is included in this
directory as well.
