libceph: revamp subs code, switch to SUBSCRIBE2 protocol

2016-03-25T17:51:38+00:00

It is currently hard-coded in the mon_client that mdsmap and monmap
subs are continuous, while osdmap sub is always "onetime".  To better
handle full clusters/pools in the osd_client, we need to be able to
issue continuous osdmap subs.  Revamp subs code to allow us to specify
for each sub whether it should be continuous or not.

Although not strictly required for the above, switch to SUBSCRIBE2
protocol while at it, eliminating the ambiguity between a request for
"every map since X" and a request for "just the latest" when we don't
have a map yet (i.e. have epoch 0).  SUBSCRIBE2 feature bit is now
required - it's been supported since pre-argonaut (2010).

Move "got mdsmap" call to the end of ceph_mdsc_handle_map() - calling
in before we validate the epoch and successfully install the new map
can mess up mon_client sub state.

libceph: advertise support for keepalive2

2015-09-17T17:14:27+00:00

We are the client, but advertise keepalive2 anyway - for consistency,
if nothing else.  In the future the server might want to know whether
its clients support keepalive2.
