From 71c265816dd2772f89ebb377381c836dfca09d70 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Tue, 15 Mar 2016 19:34:30 +0100 Subject: ivshmem: Don't destroy the chardev on version mismatch MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Yes, the chardev is commonly useless after we read a bad version from it, but destroying it is inappropriate anyway: the user created it, so the user should be able to hold on to it as long as he likes. We don't destroy it on other errors. Screwed up in commit 5105b1d. Stop reading instead. Also note QEMU's behavior in ivshmem-spec.txt.
