Getting op context in 'glusterd_op_gsync_set' is no longer
valid as it is expected that 'rsp_dict' sent from caller is
filled. It was fine till now as no one was setting the op
context. The introduction of volume locks sets it,
consequently breaking geo-rep status command. Hence the
code that gets dict from op context if present is removed.
Also corrected some indentation issues in 'glusterd_op_gsync_set'

New function 'glusterd_gsync_op_already_set' is written which compares
the geo-rep configuration value in gsync.conf with the one sent from
cli. The generic function is written to compare op_value for any
op_name sent from cli as this issue can happen with any configuration
setting other than use-tarssh also. This routine is used to avoid
restart of gsyncd if the configuration value is set to same as in
gsyncd.conf.
Also added error checking when glusterd_gsync_configure fails.
Earlier, eventhough 'glusterd_gsync_configure' fails, error
was not getting catched and success message was shown.

In staging phase of volume stop, code is added to read the state_file
for each slave of the master to which the volume belongs. If any of the
geo-rep session is active with at least one slave, volume is not
allowed to stop else it is allowed.

Slave's xtime is now stored on the master itself (and that too only on
the root), which implies it cannot be propogated to the cascaded slave.
Thus the intermediate master now makes use of it's own volume information
to propogate volume-mark and xtime.
On starting Geo-Replication "geo-replication.ignore-pid-check" marker
option is enabled, which is an override for the client-pid check in
marker. This options triggers marker update only for geo-replication
auxillary mount (client-pid == -1). Since gsyncd not does setxattr()
directly on the bricks, this option won't trigger a chain of spurious
metadata updates that would need to be processed by gsyncd.

Performing statefile check in case of geo-rep stop, so as to provide
proper error message in case session is not created.
However in case of geo-rep stop force, we allow the command to succeed
even in case that the session is not created, because the stop command
is a failsafe command to stop running geo-rep sessions on any nodes.

gsyncd was already running on that node, then all gsyncd
processes running on that node, for that particular master
and any slave sessions will be restarted

brick, the user has to perform the following steps:
1. gluster system:: execute gsec_create
2. gluster volume geo-replication <master-vol> <slave-vol> create push-pem force

message if the slave verification fails.
However it will not return true if the config file is deleted, ot corrupted,
so as not to get the state_file's path. It will also fail if the slave url
is invalid. If the push-pem option is given and
/var/lib/glusterd/geo-replication/common_secret.pem.pub is not present, then
also the create force command will fail.

There are primarily three lists that are part of glusterd process,
that are concurrently accessed. Namely, priv->volumes, priv->peers
and volinfo->bricks_list.
Big-lock approach
-----------------
WHAT IS IT?
Big lock is a coarse-grained lock which protects all three
lists, mentioned above, from racy access.
HOW DOES IT WORK?
At any given point in time, glusterd's thread(s) are in execution
_iff_ there is a preceding, inbound network event. Of course, the
sigwaiter thread and timer thread are exceptions.
A network event is an external trigger to glusterd, via the epoll
thread, in the form of POLLIN and POLLERR.
As long as we take the big-lock at all such entry points and yield
it when we are done, we are guaranteed that all the network events,
accessing the global lists, are serialised.
This amounts to holding the big lock at
- all the handlers of all the actors in glusterd. (POLLIN)
- all the cbks in glusterd. (POLLIN)
- rpc_notify (DISCONNECT event), if we access/modify
one of the three lists. (POLLERR)
In the case of synctask'ized volume operations, we must remember that,
if we held the big lock for the entire duration of the handler,
we may block other non-synctask rpc actors from executing.
For eg, volume-start would block in PMAP SIGNIN, if done incorrectly.
To prevent this, we need to yield the big lock, when we yield the
synctask, and reacquire on waking up of the synctask.

Users are still using geo-rep with the old, deprecated, insecure, unsupported
ssh setup. Not their fault -- the implementation of the new method had the
following charasteristics:
- old method is possible, but with default settings it's not working
- it can be made operational by fiddling with "remote-gsyncd" tunable
- with default setting, an unhelpful, actually misleading error message is
produced
- the UI gave no hint to the changes in the ssh setup
http://review.gluster.org/4392 tried to fix these; what it accomplished was
unrestricted support to the bad practice (by making the default old setup
operational).
From this on:
- we disable the old method by reserving the "remote-gsyncd" tunable
- if the old method is attempted, give a hint what to do

PROBLEM:
When a transaction is already in progress, and the user tries to
execute another glusterd operation, the second operation fails as
glusterd fails to acquire lock. But to the user, a message like
"Operation failed" does not give ample information about why the
operation failed.
FIX:
Made glusterd_op_txn_begin use and initialise error string, which is
needed to capture failure in the "lock" phase.
Also made gd_sync_task_begin set error string appropriately when
locking fails.
In the process, I had to introduce error string in some glusterd_handle_*
functions. And because I introduced error string in these handlers, I
decided to also set them in places where these handlers could possibly
fail.
HOW I TESTED IT:
For want of a better idea, I "commented out" the call to
"glusterd_unlock", recompiled glusterd and ran two glusterd volume
operations, one after the other. The second operation fails with the
message "Another transaction is in progress. Please try again after
sometime." as expected.
The tests were performed on two volume ops : one of them
synctask'ized (volume start) and the other NOT (volume create).

PROBLEM:
In the existing implementation, the success/failure of
execution of a command is decided (and logged) in glusterd
handler functions. Strictly speaking, the logging mechanism
must take into account what course the command takes within
the state machine before concluding whether it succeeded or
failed.
FIX:
This patch attempts to fix the above issue for vol commands.
The format of the log message is as follows:
for failure:
<command string> : FAILED : <cause of failure>
for success:
<command string> : SUCCESS
APPROACH (in a nutshell):
* The command string is packed into dict at cli and sent to
glusterd.
* glusterd logs the command status just before doing a
"submit_reply", which is called (either directly or
indirectly via a call to glusterd_op_cli_send_response)
at 2 places for every vol command:
i. in handler functions, and
ii. in glusterd_op_txn_complete
In short, the failure of a command in the handler implies the
command has indeed failed. However, its success in the handler
does NOT necessarily mean the command succeeded/will succeed.

In glusterd_urltransform, a failed GF_REALLOC would clobber
the would-be-realloc'd buffer, linearr, with a NULL pointer,
(thus leaking that memory) and then control would pass to the
error-handling code that would attempt to free
(via glusterd_urltransform_free) linearr[i], which is almost
guaranteed to segfault when linearr is NULL.

glusterd_gsync_read_frm_status reads what is expected to be a NUL-
terminated status string from the specified file, but makes two
mistakes when trying to do the favor of trimming trailing spaces.
Do not let a leading NUL byte of status cause us to read buf[-1]
and possibly to clear that and any preceding "trailing" spaces.
Do not let a blen-byte input (with no NUL byte) cause our use of
strlen to access beyond the end of non-NUL-terminated buffer.
I looked at this code because coverity reported that it was
assuming a read-provided buffer to be NUL-terminated.

- gluster vol geo-rep M S conf checkpoint <LABEL|now>
sets a checkpoint with LABEL (the keyword "now" is special,
it's rendered to the label "as of <timestamp of current time>")
that's used to refer to the checkpoint in the sequel.
(Technically, gsyncd makes a note of the xtime of master's root
as of setting the checkpoint, called the "checkpoint target".)
- gluster vol geo-rep M S conf \!checkpoint
deletes the checkpoint.
- gluster vol geo-rep M S stat
if status is OK, and there is a checkpoint configured, the checkpoint
info is appended to status (either "not yet reached", or
"completed at <timestamp of completion>").
(Technically, the worker runs a thread that monitors / serializes /
verifies checkpoint status, and answers checkpoint status requests
through a UNIX socket; monitoring boils down to querying the xtime
of slave's root and comparing with the target.)
- gluster vol geo-rep M S conf log-file | xargs grep checkpoint
displays the checkpoint history. Set, delete and completion events
are logged properly.

A commonly faced problem among glusterfs users is: after a fresh
installation of glusterfs in a virtual machine, the VM image is
cloned to make multiple instances of the server. This breaks
glusterd because right after glusterfs installation on the first
boot glusterd would have created the node UUID and this gets
inherited into the clone. The result is wierd behavior at the time
of peer probe where glusterd does not (yet) deal with UUID
collisions in a user friendly way.
This patch is for the 'prevention' of the issue. The approach here
is to avoid generating a UUID on the first start of glusterd, but
instead generate a node UUID only when a node UUID is found to be
necessary. This naturally avoids the creation of node UUID on first
boot and prevents the issue to a large extent.
This issue also needs a 'cure' patch, which gives more meaningful
error messages to the user and provides CLI to recover from the
situations (gluster peer reset?)

- fix the hilarious fd leak of "geo-rep status"
- instead of "corrupt", which can trip up users to think their
data is in danger, use the term "defunct" to describe the
condition when gsyncd is dead/unresponsive
- don't use buffered I/O when unnecessary
- stop using PATH_MAX for sizing buffers that don't hold paths
- some cleanups wrt. memory management
