commit a72b69dc083a931422cc8a5e33841aff7d5312f2 upstream. The vhost_vsock->guest_cid field is uninitialized when /dev/vhost-vsock is opened until the VHOST_VSOCK_SET_GUEST_CID ioctl is called. kvmalloc(..., GFP_KERNEL | __GFP_RETRY_MAYFAIL) does not zero memory. All other vhost_vsock fields are initialized explicitly so just initialize this field too. Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Michael S.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
