While trying to debug/test some vbutil_kernel changes (coming in a different CL) it was noticed that this utility is not covered by tests, and the script which runs it to set up further testing (tests/gen_fuzz_test_cases.sh) fails because of the key format mismatch. Some investigation has shown that this was left behind when vboot_reference key storage format was changed. To make gen_fuzz_test_cases.sh work again a new set of test keys is required, the keys are generated by tests/gen_test_keys.sh. This utility had to be changed to generate the proper set of wrapped public and private keys. Actually code in tests/gen_test_keys.shgenerate_keys() is copied in pasted in many scripts in this tree, this has to be refactored, but under a different CL. Once the changes were made, two scripts were run: ./tests/gen_test_keys.sh ./gen_test_cases.sh resulting in the new and updated keys generated. firmware/stub/tpm_lite_stub.c was edited to fix compilation warning issued when compiling with debugging enabled. Change-Id: I26a45cbad00d21a29195f2a89b4df7d3559133fe BUG=chromium-os:7178 TEST=described below The following commands succeed: vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv make make runtests ./tests/gen_fuzz_test_cases.sh ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ note that ./tests/gen_fuzz_test_cases.sh was failing before this change. The upcoming CL modifying vbutil_kernel will make sure gen_fuzz_test_cases.sh is executed when tests are run and will enhance it to cover vbutil_kernel testing.
