- * In Linux, we implement the KVP functionality in two components:
- * 1) The kernel component which is packaged as part of the hv_utils driver
- * is responsible for communicating with the host and responsible for
- * implementing the host/guest protocol. 2) A user level daemon that is
- * responsible for data gathering.
- *
- * Host/Guest Protocol: The host iterates over an index and expects the guest
- * to assign a key name to the index and also return the value corresponding to
- * the key. The host will have atmost one KVP transaction outstanding at any
- * given point in time. The host side iteration stops when the guest returns
- * an error. Microsoft has specified the following mapping of key names to
- * host specified index:
- *
- * Index Key Name
- * 0 FullyQualifiedDomainName
- * 1 IntegrationServicesVersion
- * 2 NetworkAddressIPv4
- * 3 NetworkAddressIPv6
- * 4 OSBuildNumber
- * 5 OSName
- * 6 OSMajorVersion
- * 7 OSMinorVersion
- * 8 OSVersion
- * 9 ProcessorArchitecture
- *
- * The Windows host expects the Key Name and Key Value to be encoded in utf16.
- *
- * Guest Kernel/KVP Daemon Protocol: As noted earlier, we implement all of the
- * data gathering functionality in a user mode daemon. The user level daemon
- * is also responsible for binding the key name to the index as well. The
- * kernel and user-level daemon communicate using a connector channel.
- *
- * The user mode component first registers with the
- * the kernel component. Subsequently, the kernel component requests, data
- * for the specified keys. In response to this message the user mode component
- * fills in the value corresponding to the specified key. We overload the
- * sequence field in the cn_msg header to define our KVP message types.
- *
- *
- * The kernel component simply acts as a conduit for communication between the
- * Windows host and the user-level daemon. The kernel component passes up the
- * index received from the Host to the user-level daemon. If the index is
- * valid (supported), the corresponding key as well as its
- * value (both are strings) is returned. If the index is invalid
- * (not supported), a NULL key string is returned.

- * As we look at expanding the KVP functionality to include

- * compatibility with older daemons.
- *
- * The KVP opcodes are defined by the host and it was unfortunate
- * that I chose to treat the registration operation as part of the
- * KVP operations defined by the host.
- * Here is the level of compatibility
- * (between the user level daemon and the kernel KVP driver) that we
- * will implement:
- *
- * An older daemon will always be supported on a newer driver.
- * A given user level daemon will require a minimal version of the
- * kernel driver.
- * If we cannot handle the version differences, we will fail gracefully
- * (this can happen when we have a user level daemon that is more
- * advanced than the KVP driver.
- *
- * We will use values used in this handshake for determining if we have
- * workable user level daemon and the kernel driver. We begin by taking the
- * registration opcode out of the KVP opcode namespace. We will however,
- * maintain compatibility with the existing user-level daemon code.
