Subject: Disable hgfsServer plugin when not running in a VMware VM.
X-Git-Tag: stable-11.0.0~442
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ebf08325adf874723c86aa313954492101117934;p=thirdparty%2Fopen-vm-tools.git

Disable hgfsServer plugin when not running in a VMware VM.

VmCheck_GetVersion() accesses Backdoor in an unsafe manner
which is not expected to work on non-VMware environments
including physical machines. So, we need to make sure that
VmCheck_GetVersion() is called only when we are running in
a VMware VM.
