linux.git/fs/ceph/Makefile, branch v2.6.34 Linux kernel source tree ceph: add support for auth_x authentication protocol 2010-02-11T19:48:45+00:00 Sage Weil sage@newdream.net 2010-02-03T00:25:35+00:00 ec0994e48ea2aebf62ff08376227f3a9ccf46262 The auth_x protocol implements support for a kerberos-like mutual authentication infrastructure used by Ceph. We do not simply use vanilla kerberos because of scalability and performance issues when dealing with a large cluster of nodes providing a single logical service. Auth_x provides mutual authentication of client and server and protects against replay and man in the middle attacks. It does not encrypt the full session over the wire, however, so data payload may still be snooped. Signed-off-by: Yehuda Sadeh <yehuda@hq.newdream.net> Signed-off-by: Sage Weil <sage@newdream.net>

ceph: support ceph_pagelist for message payload 2009-12-23T20:12:31+00:00 Sage Weil sage@newdream.net 2009-12-23T20:12:31+00:00 58bb3b374b07a2a43315213f00a48a5ffd6d0915 The ceph_pagelist is a simple list of whole pages, strung together via their lru list_head. It facilitates encoding to a "buffer" of unknown size. Allow its use in place of the ceph_msg page vector. This will be used to fix the huge buffer preallocation woes of MDS reconnection.

ceph: negotiate authentication protocol; implement AUTH_NONE protocol 2009-11-19T00:19:57+00:00 Sage Weil sage@newdream.net 2009-11-19T00:19:57+00:00 4e7a5dcd1bbab6560fbc8ada29a840e7a20ed7bc 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.
