From: Petr Vorel <petr.vorel@xxxxxxxxx> Hi Mimi, all, I fixed 2 regressions I found in the previous implementation. I'm planning to solve problem with ima_measurements.sh (second commit). There is also other problem with loading kexec.policy and then running ima_measurements.sh on SUT with ima_policy=tcb. The latest line in ascii_runtime_measurements_sha1 was made by ima_kexec.sh: 10 b3c3b7b9da36d5cd992272d3384a783b450ce304 ima-buf sha256:ac8bd67bdaded63be9231c495585fd88edce0812d9b677e1e1e219e2dd3bcd60 key_import_test 30820286308201efa00302010202145be0234ff3adf050349b33 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 #
