libceph: update ceph_features.h

2013-12-31T18:32:09Z

This updates ceph_features.h so that it has all feature bits defined in ceph.git. In the interim since the last update, ceph.git crossed the "32 feature bits" point, and, the addition of the 33rd bit wasn't handled correctly. The work-around is squashed into this commit and reflects ceph.git commit 053659d05e0349053ef703b414f44965f368b9f0. Signed-off-by: Ilya Dryomov Reviewed-by: Sage Weil

libceph: implement RECONNECT_SEQ feature

2013-05-02T04:17:09Z

This is an old protocol extension that allows the client and server to avoid resending old messages after a reconnect (following a socket error). Instead, the exchange their sequence numbers during the handshake. This avoids sending a bunch of useless data over the socket. It has been supported in the server code since v0.22 (Sep 2010).

libceph: add support for HASHPSPOOL pool flag

2013-02-26T23:03:06Z

The legacy behavior adds the pgid seed and pool together as the input for CRUSH. That is problematic because each pool's PGs end up mapping to the same OSDs: 1.5 == 2.4 == 3.3 == ... Instead, if the HASHPSPOOL flag is set, we has the ps and pool together and feed that into CRUSH. This ensures that two adjacent pools will map to an independent pseudorandom set of OSDs. Advertise our support for this via a protocol feature flag. Signed-off-by: Sage Weil Reviewed-by: Alex Elder

ceph: update support for PGID64, PGPOOL3, OSDENC protocol features

2013-02-26T23:02:25Z

Support (and require) the PGID64, PGPOOL3, and OSDENC protocol features. These have been present in ceph.git since v0.42, Feb 2012. Require these features to simplify support; nobody is running older userspace. Note that the new request and reply encoding is still not in place, so the new code is not yet functional.
