Add a policy in ec to performs reads from same bricks as long as they
are good. Based on the gfid of the file/directory it determines the
bricks to be considered for reading.

Only server is the required argument for glfs_set_volfile_server
and both transport and port are optional. When glfs_set_volfile_server
is invocated multiple times, only on the first invocation we replace
port 0 with 24007 and transport NULL with "tcp".
Hence, replacing the parameters at the entry function is the right way.

The @owner argument tells RPC layer the xlator that owns
the connection and to which xlator THIS needs be set during
network notifications like CONNECT and DISCONNECT.
Code paths that originate from the head of a (volume) graph and use
STACK_WIND ensure that the RPC local endpoint has the right xlator saved
in the frame of the call (callback pair). This guarantees that the
callback is executed in the right xlator context.
The client handshake process which includes fetching of brick ports from
glusterd, setting lk-version on the brick for the session, don't have
the correct xlator set in their frames. The problem lies with RPC
notifications. It doesn't have the provision to set THIS with the xlator
that is registered with the corresponding RPC programs. e.g,
RPC_CLNT_CONNECT event received by protocol/client doesn't have THIS set
to its xlator. This implies, call(-callbacks) originating from this
thread don't have the right xlator set too.
The fix would be to save the xlator registered with the RPC connection
during rpc_clnt_new. e.g, protocol/client's xlator would be saved with
the RPC connection that it 'owns'. RPC notifications such as CONNECT,
DISCONNECT, etc inherit THIS from the RPC connection's xlator.

If it is provided, EDH ciphers are available.
- Introduce ssl.ec-curve option to specify an elliptic curve name. If
unspecified, ECDH ciphers are available using the prime256v1 curve.
- Introduce ssl.crl-path option to specify the directory where the
CRL hash file can be found. Setting to NULL disable CRL checking,
just like the default.
- Make all ssl.* options accessible through gluster volume set.
- In default cipher list, exclude weak ciphers instead of listing
the strong ones.
- Enforce server cipher preference.
- introduce RPC_SET_OPT macro to factor repetitive code in glusterd-volgen.c
- Add ssl-ciphers.t test to check all the features touched by this change.

This reverses the changes done by the commit
7fba3a88f1ced610eca0c23516a1e720d75160cd.
* Change the key from "memory-accounting" to "no-memory-accounting", as by
default all the glusterfs process enable memory accounting now. So to
disable memory accounting for some process, "no-mem-accounting" argument has
to be passed.

Till now, the op-version was an incrementing integer that was
incremented by 1 for every Y release (when using the X.Y.Z release
numbering). This is not flexible enough to handle backports of features
into Z releases.
Going forward, from the upcoming 3.6.0 release, the op-versions will be
multi-digit integer values composed of the version numbers, instead of a
simple incrementing integer. An X.Y.Z release will have XYZ as its
op-version. Y and Z will always be 2 digits wide and will be padded with
0 if required. This way of bumping op-versions allows for gaps in
between the subsequent Y releases. These gaps will allow backporting
features from new Y releases into old Z releases.

cluster op-version must be atleast 4 for add/remove brick to proceed.
This change is required for the new afr-changelog xattr changes that
will be done for glusterFS 3.6 (http://review.gluster.org/#/c/7155/).
In add-brick, the check is done only when replica count is increased
because only that will affect the AFR xattrs.
In remove-brick, the check is unconditional failing which there will be
inconsistencies in the client xlator names amongst the volfiles of
different peers.

With this patch we are replacing the existing cluster-wide
lock taken on glusterds across the cluster, with volume locks
which are also taken on glusterds across the cluster, but are
volume specific. So with the volume locks we are able to perform
more than one gluster operation at the same time, as long as the
operations are being performed on different volumes.
We maintain a global list of volume-locks (using a dict for a list)
where the key is the volume name, and which saves the uuid of the
originator glusterd. These locks are held and released per volume
transaction.
In order to acheive multiple gluster operations occuring at the
same time, we also separate opinfos in the op-state-machine, as a
part of this patch. To do so, we generate a unique transaction-id
(uuid) per gluster transaction. An opinfo is then associated with
this transaction id, which is used throughout the transaction. We
maintain a run-time global list(using a dict) of transaction-ids,
and their respective opinfos to achieve this.

There is an ongoing effort to integrate NFS Ganesha (
https://github.com/nfs-ganesha/nfs-ganesha/wiki ) with GlusterFS as one of
the file system back ends.
Towards this we need extensions to gfapi that can handle object based
operations. Meaning, instead of using full paths or relative paths from
cwd, it is required that we can work with APIs, like the *at POSIX
variants, to be able to create, lookup, open etc. files and directories.
Hence the objects are the files or directories themselves and we give out
handles to these objects that can be used for further operations.
This code drop is an initial implementation of the proposed APIs.
The new APIs are implemented as glfs_h_XXX variants in the file
glfs-handleops.c to mirror glfs-fops.c style. The code leverages holding
onto inode references and doling these out as opaque/cookie type objects to
the callers, to enable them to be used as handles in other operations.
An fd based approach was considered, but due to the extra footprint that
the fd structure and its counterparts would incur, this was dropped to take
the approach of holding inode references themselves.
Tested by extending glfsxmp.c to invoke and exercise the added APIs, and
further tested with a reference integration of the same as an FSAL with NFS
Ganesha.

This patch introduces op-version support for glusterfs clients.
Now, a client sends its supported op-versions during the volfile fetch request
and glusterd will return the volfile only if the client can support the current

So far there has been a global glusterfs_ctx_t object which
represents the running instance of the filesystem (client or server).
It contains the various graphs, connection to the management daemon
over which new graphs are obtained, calls stacks issued on this
filesystem, and a bunch of such things.
With the introduction of libgfapi, it is no more true that there will
be only one filesystem context in a process. Applications can
be written to use libgfapi and obtain serveral instances of different
filesystems/volumes in the same process.
This involves messy untangling of assumptions inside libglusterfs that
there would only be one global glusterfs_ctx_t and offload that
assumption to glusterfsd/ and cli/ (where it is true).

Resending Avati's syncop patch with a few bug fixes.
(please do not skip the IMPORTANT NOTES section)
* Framework for SYNChronous OPerations
--------------------------------------
This patch provides a framework for performing synchronous operations
over the underlying actual asynchronous GlusterFS FOPS.
* Use cases
-----------
1. Convenient implementation of crawler thread in replicate/pump
2. Convenient implementation of high level control flow in DVM
* Background
------------
All (almost) threads in GlusterFS are hosts for executing aysnchronous
file operations using the STACK_WIND and STACK_UNWIND primitives - as calls
and callbacks.
While the STACK_WIND and STACK_UNWIND macros provide high control for
efficiently implementing file operations in a clustered/parallel environment,
there are tasks where the nature of the task itself is sequential and
the execution performance of the task is not critical. In these cases the
complexity to implement the task with STACK_WIND/STACK_UNWIND based operations
as calls and callbacks is an overkill.
* Introduction
---------------
syncop: are wrappers around the STACK_WIND/STACK_UNWIND based asynchronous fops.
synctask: a sequential task (a C function) which uses syncops.
syncenv: an environement to schedule and execute synctasks.
The synchronicity is implemented via ucontext.h based continuations.
Execution of synchronous tasks is possible only in a synchronous environment.
Therefore, the first step is to create such an environment -
struct syncenv *env = syncenv_new (0);
This creates a synchronous environment, with a thread (scheduler) to host the
synchronous tasks. Creation of this environment is generally to be done at the
time of process initialization. Next is to spawn a synchronous task in this
environment -
int slow_self_heal (void *data);
int completion_func (int ret, void *data);
ret = synctask_new (env, slow_self_heal, completion_func, data);
Here slow_self_heal is a task which is implemented using synchronous operations.
When slow_self_heal() completes, completion_func() is called with the first
parameter as the return value of slow_self_heal(). Both these functions get
the @data argument as the same value passed to synctask_new().
int
slow_self_heal (void *data)
{
xlator_t *child = FIRST_CHILD (THIS);
fd_t *dir = NULL;
...
dir = syncop_opendir (child, loc);
entry = syncop_readdir (dir);
...
return ret;
}
* IMPORTANT NOTES
-----------------
- calling syncops in code executing outside the synchronous environment will
very likely cause and undesired blocking of the executing thread leading to
deadlocks!!
The synchronous environment is a special thread where such sleeps are safe,
and these sleeps result in the scheduler to 'swap in' other synctasks.
- syncops can put the task to sleep. DO NOT issue syncops while holding mutexes.
This is very similar to the blunder of holding a mutex and doing STACK_WIND.
- It works best when synctasks use only syncops. If a call_frame is created and
STACK_WIND'ed, the callback would very likely happen in a thread outside the
synchronous enviroment, at an undefined time - as expected. So note that the
synchronous environment does not tame the notorious behaviour of STACK_WIND.
