Backport of http://review.gluster.org/12451
In replicate volumes, when a brick is added to a replicate
group, heal to the new brick should be triggered.
Also, the new brick should not be considered as source for
healing till it is up to date.
Previously, extended attributes had to be set manually on
the bricks for this to happen. This patch is part 1 patch
to automate this process.

tiering volfiles may contain afr and disperse together
or multiple time based on configuration. And the
informations for those configurations are stored in
tier_info. So most of the volgen code generation
need to be changed to make compatible with it.

problem : Reset/set commands were not working properly. reset command returns
success but it not sending notification to svcs if corresponding graph modified.
Fix: Whenever reset/set command issued, generate the temp graph and compare
with original graph and do the fallowing actions
1.) If both graph are identical nothing to do with svcs.
2.) If any changes in graph topology restart/stop service by calling
svc manager.
3) If changes in options send notify signal by calling glusterd_fetchspec_notify.

Volume-reset shouldn't remove quota-deem-statfs, unless
explicitly specified, when quota is enabled.
1) glusterd_op_stage_reset_volume ()
'gluster volume set/reset <VOLNAME>' features.quota/
features.inode-quota' should not be allowed as it is deprecated.
Setting and resetting quota/inode-quota features should be allowed
only through 'gluster volume quota <VOLNAME> enable/disable'.
2) glusterd_enable_default_options ()
Option 'features.quota-deem-statfs' should not be turned off
with 'gluster volume reset <VOLNAME>', since quota features
can be set/reset only with 'gluster volume quota <VOLNAME>
enable/disable'.
But, 'gluster volume set features.quota-deem-statfs'
can be turned on/off when quota is enabled.

inode quota is a new feature implemented in glusterfs-3.7
if quota is enabled in the older version and is upgraded
to a new version, we can hit setxattr spike during self-heal
of inode quotas. So, when a quota is enabled, turn off
inode-quotas with a xlator option.
With this patch, we still account for inode quotas but only
when a write operation is performed for a particular file.
User will be able to query inode quotas once the Inode-quota
xlator option is enabled.

A generic and extensible framework, used to maintain states in
the glusterfsd process for each of the files accessed
(including the clients info doing the fops) and send
notifications to the respective glusterfs clients incase of
any change in that state.
This patch handles "Inode Update/Invalidation" upcall event.

This commit does the following:
1. Adds several new functions for generation of brick xlator units
in a volgen. Each such function takes care of generation of only
one xlator in volgen.
2. A new table, server_graph_table, links all individual graph generation
functions together. The order of xlator function generators in the
table determines the topology of the brick graph.
3. server_graph_builder() invokes individual graph generators by walking
through server_graph_table. Addition of debug xlators into the brick
graph is also handled by this walk. As a result, a lot of cruft that
is present in the exisiting implementation of this function gets
cleaned up.
4. get_server_xlator() now makes use of server_graph_table to determine
whether a xlator key corresponds to a server xlator or not.

For volumes with replicate, disperse xlators, self-heal daemon should do
healing. This patch provides enable/disable functionality for the xlators to be
part of self-heal-daemon. Replicate already had this functionality with
'gluster volume set cluster.self-heal-daemon on/off'. But this patch makes it
uniform for both types of volumes. Internally it still does 'volume set' based
on the volume type.

Implement reconfigure() for NFS xlator so that volume set/reset wont
restart the NFS server process. But few options can not be reconfigured
dynamically e.g. nfs.mem-factor, nfs.port etc which needs NFS to be

Current BD xlator (block backend) has a few limitations such as
* Creation of directories not supported
* Supports only single brick
* Does not use extended attributes (and client gfid) like posix xlator
* Creation of special files (symbolic links, device nodes etc) not
supported
Basic limitation of not allowing directory creation is blocking
oVirt/VDSM to consume BD xlator as part of Gluster domain since VDSM
creates multi-level directories when GlusterFS is used as storage
backend for storing VM images.
To overcome these limitations a new BD xlator with following
improvements is suggested.
* New hybrid BD xlator that handles both regular files and block device
files
* The volume will have both POSIX and BD bricks. Regular files are
created on POSIX bricks, block devices are created on the BD brick (VG)
* BD xlator leverages exiting POSIX xlator for most POSIX calls and
hence sits above the POSIX xlator
* Block device file is differentiated from regular file by an extended
attribute
* The xattr 'user.glusterfs.bd' (BD_XATTR) plays a role in mapping a
posix file to Logical Volume (LV).
* When a client sends a request to set BD_XATTR on a posix file, a new
LV is created and mapped to posix file. So every block device will
have a representative file in POSIX brick with 'user.glusterfs.bd'
(BD_XATTR) set.
* Here after all operations on this file results in LV related
operations.
For example opening a file that has BD_XATTR set results in opening
the LV block device, reading results in reading the corresponding LV
block device.
When BD xlator gets request to set BD_XATTR via setxattr call, it
creates a LV and information about this LV is placed in the xattr of the
posix file. xattr "user.glusterfs.bd" used to identify that posix file
is mapped to BD.
Usage:
Server side:
[root@host1 ~]# gluster volume create bdvol host1:/storage/vg1_info?vg1 host2:/storage/vg2_info?vg2
It creates a distributed gluster volume 'bdvol' with Volume Group vg1
using posix brick /storage/vg1_info in host1 and Volume Group vg2 using
/storage/vg2_info in host2.
[root@host1 ~]# gluster volume start bdvol
Client side:
[root@node ~]# mount -t glusterfs host1:/bdvol /media
[root@node ~]# touch /media/posix
It creates regular posix file 'posix' in either host1:/vg1 or host2:/vg2 brick
[root@node ~]# mkdir /media/image
[root@node ~]# touch /media/image/lv1
It also creates regular posix file 'lv1' in either host1:/vg1 or
host2:/vg2 brick
[root@node ~]# setfattr -n "user.glusterfs.bd" -v "lv" /media/image/lv1
[root@node ~]#
Above setxattr results in creating a new LV in corresponding brick's VG
and it sets 'user.glusterfs.bd' with value 'lv:<default-extent-size'
[root@node ~]# truncate -s5G /media/image/lv1
It results in resizig LV 'lv1'to 5G
New BD xlator code is placed in xlators/storage/bd directory.
Also add volume-uuid to the VG so that same VG can't be used for other
bricks/volumes. After deleting a gluster volume, one has to manually
remove the associated tag using vgchange <vg-name> --deltag
<trusted.glusterfs.volume-id:<volume-id>>
Changes from previous version V5:
* Removed support for delayed deleting of LVs
Changes from previous version V4:
* Consolidated the patches
* Removed usage of BD_XATTR_SIZE and consolidated it in BD_XATTR.
Changes from previous version V3:
* Added support in FUSE to support full/linked clone
* Added support to merge snapshots and provide information about origin
* bd_map xlator removed
* iatt structure used in inode_ctx. iatt is cached and updated during
fsync/flush
* aio support
* Type and capabilities of volume are exported through getxattr
Changes from version 2:
* Used inode_context for caching BD size and to check if loc/fd is BD or
not.
* Added GlusterFS server offloaded copy and snapshot through setfattr
FOP. As part of this libgfapi is modified.
* BD xlator supports stripe
* During unlinking if a LV file is already opened, its added to delete
list and bd_del_thread tries to delete from this list when a last
reference to that file is closed.
Changes from previous version:
* gfid is used as name of LV
* ? is used to specify VG name for creating BD volume in volume
create, add-brick. gluster volume create volname host:/path?vg
* open-behind issue is fixed
* A replicate brick can be added dynamically and LVs from source brick
are replicated to destination brick
* A distribute brick can be added dynamically and rebalance operation
distributes existing LVs/files to the new brick
* Thin provisioning support added.
* bd_map xlator support retained
* setfattr -n user.glusterfs.bd -v "lv" creates a regular LV and
setfattr -n user.glusterfs.bd -v "thin" creates thin LV
* Capability and backend information added to gluster volume info (and
--xml) so
that management tools can exploit BD xlator.
* tracing support for bd xlator added
TODO:
* Add support to display snapshots for a given LV
* Display posix filename for list-origin instead of gfid

This is required by Geo-Replication that does auxillary mount
with client-pid as -1 (which has special treatment at specific
places in GlusterFS), to trigger xtime updates on the intermediate
master in a cascading setup.
Marker too had a check to "not" mark updates for geo-replication's
auxillary mounts. With the new geo-replication design, xtimes are
not set by the master on the slave for all entities. Due to this
cascading setups were broken.
This patch introduces "geo-replication.ignore-pid-check" option
as a "override" for the client-pid check for gsyncd's client-pid.
When this options is enabled, marker start "marking" even if the
updates are from the special client.
Geo-Replication on the detection of itself being an intermediate
master, enables this option.

Each volume is now associated with two op-versions,
* op_version - the op-version of the highest op-versioned feature enabled
* client_op_version - the op-version of the highest op-versioned feature
enabled which affects the clients only.
These two op-versions are generated dynamically and kept updated during
runtime. Glusterd now uses the respective volumes' client-op-version during
getspec requests.
To achieve the above a new field in the vme table is introduced,
client_option, this boolean field tells if the option is a client side
option.

* PROBLEM:
When address-based authentication is enabled on a volume,
the gNfs server, self-heal daemon (shd), and other operations
such as quota, rebalance, replace-brick and geo-replication
either stop working or the services are not started if all
the peers' ipv{4,6} addresses or hostnames are not added in
the "set auth.allow" operation, breaking the functionality
of several operations.
E.g:
volume vol in a cluster of two peers:
/mnt/brick1 in 192.168.1.4
/mnt/brick2 in 192.168.1.5
option auth.allow 192.168.1.6
(allow connection requests only from 192.168.1.6)
This will disrupt the nfs servers on 192.168.1.{4,5}.
brick server processes reject connection requests from both
nfs servers (on 4,5), because the peer addresses are not in
the auth.allow list.
Same holds true for local mounts (on peer machines),
self-heal daemon, and other operations which perform
a glusterfs mount on one of the peers.
* SOLUTION:
Login-based authentication (username/password pairs,
henceforth referred to as "keys") for gluster services and
operations.
These *per-volume* keys can be used to by-pass the addr-based
authentication, provided none of the peers' addresses are put
in the auth.reject list, to enable gluster services like gNfs,
self-heal daemon and internal operations on volumes when
auth.allow option is exercised.
* IMPLEMENTATION:
1. Glusterd generates keys for each volume and stores it in
memory as well as in respective volfiles.
A new TRUSTED-FUSE volfile is generated which is
fuse volfile + keys in protocol/client,
and is named trusted-<volname>-fuse.vol.
This is used by all local mounts. ANY local mount (on any peer)
is granted the trusted-fuse volfile instead of fuse volfile
via getspec. non-local mounts are NOT granted the trusted fuse
volfile.
2. The keys generated for the volume is written to each server
volfile telling servers to allow users with these keys.
3. NFS, self-heal daemon and replace-brick volfiles are updated
with the volume's authentication keys.
4. The keys are NOT written to fuse volfiles for obvious reasons.
5. The ownership of volfiles and logfiles is restricted to root users.
6. Merging two identical definitions of peer_info_t in auth/addr
and rpc-lib, throwing away the one in auth/addr.
7. Code cleanup in numerous places as appropriate.
* IMPORTANT NOTES:
1. One SHOULD NOT put any of the peer addresses in the auth.reject
list if one wants any of the glusterd services and features
such as gNfs, self-heal, rebalance, geo-rep and quota.
2. If one wants to use username/password based authentication
to volumes, one shall append to the server, nfs and shd volfiles,
the keys one wants to use for authentication, *while_retaining
those_generated_by_glusterd*.
See doc/authentication.txt file for details.

Replace-brick didn't support transport types other than tcp.
Test case: replace-brick should work with tcp and rdma.
