selinux: vsock: Set SID for socket returned by accept()
[ Upstream commit1f935e8e72
] For AF_VSOCK, accept() currently returns sockets that are unlabelled. Other socket families derive the child's SID from the SID of the parent and the SID of the incoming packet. This is typically done as the connected socket is placed in the queue that accept() removes from. Reuse the existing 'security_sk_clone' hook to copy the SID from the parent (server) socket to the child. There is no packet SID in this case. Fixes:d021c34405
