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: buffer decoding helpers

2010-02-10T23:04:39+00:00

Helper for decoding into a ceph_buffer, and other misc decoding helpers we will need. Signed-off-by: Yehuda Sadeh Signed-off-by: Sage Weil

ceph: include type in ceph_entity_addr, filepath

2010-01-29T20:41:09+00:00

Include a type/version in ceph_entity_addr and filepath. Include extra byte in filepath encoding as necessary. 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: use fixed endian encoding for ceph_entity_addr

2009-11-03T23:17:56+00:00

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. Signed-off-by: Sage Weil

ceph: convert encode/decode macros to inlines

2009-10-14T16:59:09+00:00

This avoids the fugly pass by reference and makes the code a bit easier to read. Signed-off-by: Sage Weil

ceph: messenger library

2009-10-06T18:31:13+00:00

A generic message passing library is used to communicate with all other components in the Ceph file system. The messenger library provides ordered, reliable delivery of messages between two nodes in the system. This implementation is based on TCP. Signed-off-by: Sage Weil
