[Qemu-devel] [PATCH 01/99] tests: fix tpm-crb tpm-tis tests race

From: Michael Roth
Subject: [Qemu-devel] [PATCH 01/99] tests: fix tpm-crb tpm-tis tests race
Date: Mon, 23 Jul 2018 15:16:10 -0500

From: Marc-André Lureau <address@hidden>

No need to close the TPM data socket on the emulator end, qemu will
close it after a SHUTDOWN. This avoids a race between close() and
read() in the TPM data thread.
