mon: ConfigKeyService: stash config keys on the monitor
Building up on the Single-Paxos and our existing k/v store that backs
the monitor, we now introduce a simple service so that the monitors
act as a generic k/v store available to the cluster, in which a user
can stash (and later obtain) configuration keys at his own discretion.
Users can put, get, delete, list and check for values using the
following commands:
- ceph config-key put <key> [<value>]
or
- ceph config-key put <key> [-i <in-file>]
with 'value' and 'in-file' being optional; if these are not specified,
'put' will act as 'touch' if 'key' does not exist, or will overwrite
the value of 'key' with a zero byte value (i.e., truncates the
contents of the value to zero)
- ceph config-key get <key>
or
- ceph config-key get <key> -o <out-file>
- ceph config-key delete <key>
- ceph config-key list [-o <out-file]
- ceph config-key exists <key>

ceph.spec.in: Move four scripts from sbin to usr/bin
The ceph-create-keys, ceph-disk, ceph-disk-activate, and

them into usr/bin, and several utilities look for them there.
This commit changes the RPM to install them in /usr/bin. (Bug #3921)

ceph: propagate do_command()'s return value to user space
We were returning '1' regardless of what do_command() returned in case

short of useless, and forced them to rely instead on error messages.

client: Don't signal requests already handled
The assertion failure reported in #4530 is triggered
by the following:
1. client sends request
2. mds sends unsafe reply
3. before request gets journaled, mds is killed
4. mds restarts
5. client receives session close (from close request before restart)
6. session close does kick_requests()
7. kick_requests tries to signal caller that doesn't exist.
This fix avoids signaling a caller if the unsafe reply
has been received and the make_request() function has completed.
We do this by setting the caller_cond to null once the caller
is woken up, and only signal the caller in kick_requests if
caller_cond is non-null. This avoids trying to resend requests
listed in mds_request but that have already received unsafe replies.
The unsafe requests are handled by resend_unsafe_requests() code,
so skipping those requests is allowable.

fix append to uninitialized buffer in FlatIndex::created
The long_name variable is not initialized. When the append_oname
function is called, it will strlen(long_name) and get a result
that depends on the stack content. The long_name is truncated to a
zero length string to prevent this unexpected behavior.
There is no sure way to trigger the problem by writing a unit
test. Unit tests are added for all public methods of the FlatIndex
class. Most of the time the tests fail if the long_name variable is
not properly initialized.
* uint32_t collection_version()
* coll_t coll() const
* void set_ref(std::tr1::shared_ptr<CollectionIndex> ref)
* int cleanup()
* int init()
* int created(const hobject_t &hoid, const char *path)
* int unlink(const hobject_t &hoid)
* int lookup(const hobject_t &hoid, IndexedPath *path, int *exist)
* int collection_list(vector<hobject_t> *ls)
* int collection_list_partial(const hobject_t &start, int min_count, int max_count, snapid_t seq, vector<hobject_t> *ls, hobject_t *next)
There are a number of border cases that cannot be tested, such as the
logic of the lfn_get static function. Since FlatIndex code is designed
to transition from older namespace conventions, it is difficult to
figure out.
The tests rely on xattr(2) and their availability is checked before
running them.
