ceph: factor out libceph from Ceph file system

2010-10-20T22:37:28+00:00

This factors out protocol and low-level storage parts of ceph into a separate libceph module living in net/ceph and include/linux/ceph. This is mostly a matter of moving files around. However, a few key pieces of the interface change as well: - ceph_client becomes ceph_fs_client and ceph_client, where the latter captures the mon and osd clients, and the fs_client gets the mds client and file system specific pieces. - Mount option parsing and debugfs setup is correspondingly broken into two pieces. - The mon client gets a generic handler callback for otherwise unknown messages (mds map, in this case). - The basic supported/required feature bits can be expanded (and are by ceph_fs_client). No functional change, aside from some subtle error handling cases that got cleaned up in the refactoring process. Signed-off-by: Sage Weil

ceph: negotiate authentication protocol; implement AUTH_NONE protocol

2009-11-19T00:19:57+00:00

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. Signed-off-by: Sage Weil

ceph: on-wire types

2009-10-06T18:31:06+00:00

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. Signed-off-by: Sage Weil
