ceph: factor out libceph from Ceph file system

2010-10-20T22:37:28Z

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: messenger and osdc changes for rbd

2010-10-20T22:37:18Z

Allow the messenger to send/receive data in a bio. This is added so that we wouldn't need to copy the data into pages or some other buffer when doing IO for an rbd block device. We can now have trailing variable sized data for osd ops. Also osd ops encoding is more modular. Signed-off-by: Yehuda Sadeh Signed-off-by: Sage Weil

ceph: specify supported features in super.h

2010-08-02T03:11:41Z

Specify the supported/required feature bits in super.h client code instead of using the definitions from the shared kernel/userspace headers (which will go away shortly). Signed-off-by: Sage Weil

ceph: fix creation of ipv6 sockets

2010-07-09T22:00:20Z

Use the address family from the peer address instead of assuming IPv4. Signed-off-by: Sage Weil

ceph: fix parsing of ipv6 addresses

2010-07-09T22:00:18Z

Check for brackets around the ipv6 address to avoid ambiguity with the port number. Signed-off-by: Sage Weil

ceph: fix printing of ipv6 addrs

2010-07-08T23:49:53Z

The buffer was too small. Make it bigger, use snprintf(), put brackets around the ipv6 address to avoid mixing it up with the :port, and use the ever-so-handy %pI[46] formats. Signed-off-by: Sage Weil

ceph: fix message revocation

2010-07-05T19:16:23Z

A message can be on a queue (pending or sent), or out_msg (sending), or both. We were assuming that if it's not on a queue it couldn't be out_msg, but that was false in the case of lossy connections like the OSD. Fix ceph_con_revoke() to treat these cases independently. Also, fix the out_kvec_is_message check to only trigger if we are currently sending _this_ message. This fixes a GPF in tcp_sendpage, triggered by OSD restarts. Signed-off-by: Sage Weil

ceph: fix message memory leak, uninitialized variable

2010-06-13T17:34:36Z

We need to properly initialize skip, as not all alloc_msg op instances set it. Also, BUG if someone says skip but also allocates a message. Signed-off-by: Sage Weil
