67 * In FreeBSD, we implement the KVP functionality in two components:
68 * 1) The kernel component which is packaged as part of the hv_utils driver
69 * is responsible for communicating with the host and responsible for
70 * implementing the host/guest protocol. 2) A user level daemon that is
71 * responsible for data gathering.
72 *
73 * Host/Guest Protocol: The host iterates over an index and expects the guest
74 * to assign a key name to the index and also return the value corresponding to
75 * the key. The host will have atmost one KVP transaction outstanding at any
76 * given point in time. The host side iteration stops when the guest returns
77 * an error. Microsoft has specified the following mapping of key names to
78 * host specified index:
79 *
80 * Index Key Name
81 * 0 FullyQualifiedDomainName
82 * 1 IntegrationServicesVersion
83 * 2 NetworkAddressIPv4
84 * 3 NetworkAddressIPv6
85 * 4 OSBuildNumber
86 * 5 OSName
87 * 6 OSMajorVersion
88 * 7 OSMinorVersion
89 * 8 OSVersion
90 * 9 ProcessorArchitecture
91 *
92 * The Windows host expects the Key Name and Key Value to be encoded in utf16.
93 *
94 * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
95 * data gathering functionality in a user mode daemon. The user level daemon
96 * is also responsible for binding the key name to the index as well. The
97 * kernel and user-level daemon communicate using a connector channel.
98 *
99 * The user mode component first registers with the
100 * the kernel component. Subsequently, the kernel component requests, data
101 * for the specified keys. In response to this message the user mode component
102 * fills in the value corresponding to the specified key. We overload the
103 * sequence field in the cn_msg header to define our KVP message types.
104 *
105 *
106 * The kernel component simply acts as a conduit for communication between the
107 * Windows host and the user-level daemon. The kernel component passes up the
108 * index received from the Host to the user-level daemon. If the index is
109 * valid (supported), the corresponding key as well as its
110 * value (both are strings) is returned. If the index is invalid
111 * (not supported), a NULL key string is returned.
