These are WIP taken from git@github.com:stefanha/linux.git#vsock (==4c9d2a6be1c6, using "cherry-pick -x") and correspond to RFC v5 of the frontend patches posted in http://thread.gmane.org/gmane.linux.kernel.virtualization/27455 There is no corresponding spec proposal update yet, but this set of patches correspond (roughly) to addressing the feedback on v4 of the spec proposal http://thread.gmane.org/gmane.comp.emulators.virtio.devel/1062. kernel_config.arm modifications copied from x86, not tested. Added /etc/kernel-patches/ directory to the image to be consumed by the licensing. Signed-off-by: Ian Campbell <ian.campbell@docker.com>

Subject: [PATCH 9/9] VSOCK: Only allow host network namespace to use AF_VSOCK.
|
|
|
|
The VSOCK addressing schema does not really lend itself to simply creating an
|
|
alternative end point address within a namespace.
