From d64072c0ac6f73413026695bb33a4aa232e69617 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Thu, 23 Jul 2020 13:58:44 +0200 Subject: Revert "tpm: Clean up error reporting in tpm_init_tpmdev()" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts commit d10e05f15d5c3dd5e5cc59c5dfff460d89d48580. We report some -tpmdev failures, but then continue as if all was fine. Reproducer: $ qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -chardev null,id=tpm0 -tpmdev emulator,id=tpm0,chardev=chrtpm -device tpm-tis,tpmdev=tpm0 qemu-system-x86_64: -tpmdev emulator,id=tpm0,chardev=chrtpm: tpm-emulator: tpm chardev 'chrtpm' not found. qemu-system-x86_64: -tpmdev emulator,id=tpm0,chardev=chrtpm: tpm-emulator: Could not cleanly shutdown the TPM: No such file or directory QEMU 5.0.90 monitor - type 'help' for more information (qemu) qemu-system-x86_64: -device tpm-tis,tpmdev=tpm0: Property 'tpm-tis.tpmdev' can't find value 'tpm0' $ echo $? 1 This is a regression caused by commit d10e05f15d "tpm: Clean up error reporting in tpm_init_tpmdev()". It's incomplete: be->create(opts) continues to use error_report(), and we don't set an error when it fails. I figure converting the create() methods to Error would make some sense, but I'm not sure it's worth the effort right now. Revert the broken commit instead, and add a comment to tpm_init_tpmdev(). Straightforward conflict in tpm.c resolved.
