Sage Weil dbad185d49 ceph: drop src address(es) from message header [new protocol feature]
The CEPH_FEATURE_NOSRCADDR protocol feature avoids putting the full source
address in each message header (twice).  This patch switches the client to
the new scheme, and _requires_ this feature on the server.  The server
will support both the old and new schemes.  That means an old client will
work with a new server, but a new client will not work with an old server.

Sage Weil ac8839d7b2 ceph: include type in ceph_entity_addr, filepath
Include a type/version in ceph_entity_addr and filepath.  Include extra
byte in filepath encoding as necessary.

Sage Weil 103e2d3ae5 ceph: remove unused erank field
The ceph_entity_addr erank field is obsolete; remove it.  Get rid of
trivial addr comparison helpers while we're at it.

Sage Weil 04a419f908 ceph: add feature bits to connection handshake (protocol change)
Define supported and required feature set.  Fail connection if the server
requires features we do not support (TAG_FEATURES), or if the server does
not support features we require.

Sage Weil 6df058c025 ceph: include transaction id in ceph_msg_header (protocol change)
Many (most?) message types include a transaction id.  By including it in
the fixed size header, we always have it available even when we are unable
to allocate memory for the (larger, variable sized) message body.  This
will allow us to error out the appropriate request instead of (silently)
dropping the reply.

Sage Weil 4e7a5dcd1b ceph: negotiate authentication protocol; implement AUTH_NONE protocol
When we open a monitor session, we send an initial AUTH message listing
the auth protocols we support, our entity name, and (possibly) a previously
assigned global_id.  The monitor chooses a protocol and responds with an
initial message.

Initially implement AUTH_NONE, a dummy protocol that provides no security,
but works within the new framework.  It generates 'authorizers' that are
used when connecting to (mds, osd) services that simply state our entity
name and global_id.

This is a wire protocol change.

Sage Weil 63f2d21195 ceph: use fixed endian encoding for ceph_entity_addr
We exchange struct ceph_entity_addr over the wire and store it on disk.
The sockaddr_storage.ss_family field, however, is host endianness.  So,
fix ss_family endianness to big endian when sending/receiving over the
wire.

Sage Weil 535bbb5307 ceph: add version field to message header
This makes it easier for individual message types to indicate
their particular encoding, and make future changes backward
compatible.

Sage Weil 0dee3c28af ceph: on-wire types
These headers describe the types used to exchange messages between the
Ceph client and various servers.  All types are little-endian and
packed.  These headers are shared between the kernel and userspace, so
all types are in terms of e.g. __u32.

Additionally, we define a few magic values to identify the current
version of the protocol(s) in use, so that discrepancies to be
detected on mount.
