vmci: read overrun bug in dg_dispatch_as_host() (drivers/misc/vmw_vmci/vmci_datagram.c)
...sed for local communication.
The bug occurs for the IOCTL_VMCI_DATAGRAM_SEND ioctl, and our tool reports the following partial backtrace:

#3 vmci_host_do_send_datagram () at drivers/misc/vmw_vmci/vmci_host.c:404
Here?s the relevant code snippet from dg_dispatch_as_host():
171: dg_size = VMCI_DG_SIZE(dg);
...
235: dg_info = kmalloc(sizeof(*dg_info) +
236: (size_t) dg->payload_size, GFP_ATOMIC);

[PATCH 00/12] VMCI for Linux upstreaming
..., vmci_privilege_flags.
Use C99 style initialization for struct VMCI_INVALID_HANDLE.
Use inline function instead of macro for VMCI_HANDLE_INVALID.
No change for vmw_vmci_api.h location (under include/linux/ directory).
No change for macros VMCI_CONTEXT_IS_VM, VMCI_HOST_CONTEXT_ID,
VMCI_RESERVED_CID_LIMIT, VMCI_HYPERVISOR_CONTEXT_ID and
VMCI_WELL_KNOWN_CONTEXT_ID. Still in header file include/linux/vmw_vmci_defs.h
This addresses Greg's several comments on Thu, 15 Nov 2012 16:01:18 -0800
