The restarting of bricks has been deffered until the cluster 'stabilizes'
itself volumes' view. Since glusterd_spawn_daemons is executed everytime
a peer 'joins' the cluster, it may inadvertently restart bricks that
were taken offline for say, maintenance purposes. This fix avoids that.

Before Anonymous fds are available, afr had to queue up
transactions if the file is not opened on one of its
subvolumes. This happens until the attempt to open the
file either succeeds or fails. These attempts happen
until the file is successfully opened on the subvolume.
Now client xlator uses anonymous fds to perform the fops
if the fd used for the fop is not 'opened'.
Fops will be successful even when the file is not opened
so there is no need to queue up the transactions anymore in afr.
Open is attempted on the subvolume where it is not
opened independent of the fop.

posix_fill_readdir() is a multi-step function which performs many
readdir() calls, and expects the directory cursor to have not
"seeked away" elsewhere between two successive iterations. Usually
this is not a problem as each opendir() from an application has its
own backend fd, and there is nobody else to "seek away" the directory
cursor. However in case of NFS's use of anonymous fd, the same fd_t
is shared between all NFS readdir requests, and two readdir loops can
be executing in parallel on the same dir dragging away the cursor in
a chaotic manner.
The fix in this patch is to lock on the fd around the loop. Another
approach could be to reimplement posix_fill_readdir() with a single
getdents() call, but that's for another day.

Historic bug - posix_writev() has been inspecting pfd->flushwrites for
performing fsync() after write, instead of @flags for O_SYNC|O_DSYNC.
pfd->flushwrites was never set anywhere and is unused completely. This
is behavior from the time before anonymous FD where open() had @wbflags
param. This is a leftover from that cleanup.

Problem:
With the present implementation, eager-lock is issued for
any fd fop. eager-lock is being transferred to metadata
transactions. But the lk-owner is set to local->fd address
only for DATA transactions, but for METADATA transactions
it is frame->root. Because of this unlock on the eager-lock fails
and rebalance hangs.
Fix:
Enable eager-lock for fd DATA transactions

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.

glusterd syncops perform a barrier_wake whenever rpc_clnt_submit returned -1.
This is based on the wrong assumption that the cbkfn wasn't called.
This would result in one more wakeup than there ought to be.

If for some reason glusterd_get_brick_root() fails,
it frees the gf_strdup'ed *mount_point in its own error path,
and returns -1.
Unfortunately it already had assigned that pointer value
to the output argument, the caller function
glusterd_add_brick_detail() sees a non-NULL pointer,
and free() again: segfault.
Could be fixed with a one-liner (*mount_point = NULL)
in the error path, but I think glusterd_get_brick_root()
should only assign to the output argument once all checks passed,
so I use a local temporary pointer, which increases the patch a bit.

This is needed to support automated testing of cluster-communication
features such as probing and quorum. In order to use this, you need to
do the following preparatory steps.
* Copy /var/lib/glusterd to another directory for each virtual host
* Ensure that each virtual host has a different UUID in its glusterd.info
Now you can start each copy of glusterd with the following xlator-options.
* management.transport.socket.bind-address=$ip_address
* management.working-directory=$unique_working_directory
You can use 127.x.y.z addresses for binding without needing to assign
them to interfaces explicitly. Note that you must use addresses, not
names, because of some stuff in the socket code that's not worth fixing
just for this usage, but after that you can use names in /etc/hosts
instead.
At this point you can issue CLI commands to a specific glusterd using
the --remote-host option. So far probe, volume create/start/stop,
mount, and basic I/O all seem to work as expected with multiple
instances.

Problem:
Data self-heal may choose sink iatt to set mtimes.
This happens because after syncing of data is done
self-heal does one more xattrops/fstat to determine
sources sinks to set the inode-ctx. Since this is done
after data syncing and erase of xattrs, old source and
old sink are now sources, but the mtimes of them differ.
Old code just takes the first source from the list and
update mtimes, which could be sink before the self-heal
started.
Fix:
Set mtime from 'sources before syncing'.

Backporting fix http://review.gluster.org/#/c/4668/
When subvols-per-directory is < available subvols, then there are layouts
which are not populated. This leads to incorrect identification of holes or
overlaps. We need to ignore layouts, which have err == 0, and start == stop.
In the current scenario (start == stop == 0).
Additionally, in layout-merge, treat missing xattrs as err = 0. In case of
missing layouts, anomalies will reset them.
For any other valid subvoles, err != 0 in case of layouts being zeroed out.
Also reverted back dht_selfheal_dir_xattr, which does layout calculation only
on subvols which have errors.

Backporting Avati's fix http://review.gluster.org/4711
The scheme to encode brick d_off and brick id into global d_off has
two approaches. Since both brick d_off and global d_off are both 64-bit
wide, we need to be careful about how the brick id is encoded.
Filesystems like XFS always give a d_off which fits within 32bits. So
we have another 32bits (actually 31, in this scheme, as seen ahead) to
encode the brick id - which is typically plenty.
Filesystems like the recent EXT4 utilize the upto 63 low bits in d_off,
as the d_off is calculated based on a hash function value. This leaves
us no "unused" bits to encode the brick id.
However both these filesystmes (EXT4 more importantly) are "tolerant" in
terms of the accuracy of the value presented back in seekdir(). i.e, a
seekdir(val) actually seeks to the entry which has the "closest" true
offset.
This "two-prong" scheme exploits this behavior - which seems to be the
best middle ground amongst various approaches and has all the advantages
of the old approach:
- Works against XFS and EXT4, the two most common filesystems out there.
(which wasn't an "advantage" of the old approach as it is borken against
EXT4)
- Probably works against most of the others as well. The ones which would
NOT work are those which return HUGE d_offs _and_ NOT tolerant to
seekdir() to "closest" true offset.
- Nothing to "remember in memory" or evict "old entries".
- Works fine across NFS server reboots and also NFS head failover.
- Tolerant to seekdir() to arbitrary locations.
Algorithm:
Each d_off can be encoded in either of the two schemes. There is no
requirement to encode all d_offs of a directory or a reply-set in
the same scheme.
The topmost bit of the 64 bits is used to specify the "type" of encoding
of this particular d_off. If the topmost bit (bit-63) is 1, it indicates
that the encoding scheme holds a HUGE d_off. If the topmost bit is is 0,
it indicates that the "small" d_off encoding scheme is used.
The goal of the "small" d_off encoding is to stay as dense as possible
towards the lower bits even in the global d_off.
The goal of the HUGE d_off encoding is to stay as accurate (close) as
possible to the "true" d_off after a round of encoding and decoding.
If DHT has N subvolumes, we need ROOF(Log2(N)) "bits" to encode the brick
ID (call it "n").
SMALL d_off
===========
Encoding
--------
If the top n + 1 bits are free in a brick offset, then we leave the
top bit as 0 and set the remaining bits based on the old formula:
hi_mask = 0xffffffffffffffff
hi_mask = ~(hi_mask >> (n + 1))
if ((hi_mask & d_off_brick) != 0)
do_large_d_off_encoding ()
d_off_global = (d_off_brick * N) + brick_id
Decoding
--------
If the top bit in the global offset is 0, it indicates that this
is the encoding formula used. So decoding such a global offset will
be like the old formula:
if ((d_off_global & 0x8000000000000000) != 0)
do_large_d_off_decoding()
d_off_brick = (d_off_global % N)
brick_id = d_off_global / N
HUGE d_off
==========
Encoding
--------
If the top n + 1 bits are NOT free in a given brick offset, then we
set the top bit as 1 in the global offset. The low n bits are replaced
by brick_id.
low_mask = 0xffffffffffffffff << n // where n is ROOF(Log2(N))
d_off_global = (0x8000000000000000 | d_off_brick & low_mask) + brick_id
if (d_off_global == 0xffffffffffffffff)
discard_entry();
Decoding
--------
If the top bit in the global offset is set 1, it indicates that
the encoding formula used is above. So decoding would look like:
hi_mask = (0xffffffffffffffff << n)
low_mask = ~(hi_mask)
d_off_brick = (global_d_off & hi_mask & 0x7fffffffffffffff)
brick_id = global_d_off & low_mask
If "losing" the low n bits in this decoding of d_off_brick looks
"scary", we need to realize that till recently EXT4 used to only
return what can now be expressed as (d_off_global >> 32). The extra
31 bits of hash added by EXT recently, only decreases the probability
of a collision, and not eliminate it completely, anyways. In a way,
the "lost" n bits are made up by decreasing the probability of
collision by sharding the files into N bricks / EXT directories
-- call it "hash hedging", if you will :-)

We needed to zero out the layout range, before we re-calculate the range.
When spread-count is issued, we would end up with stale ranges in the layout.
Replaced dht_selfheal_dir_xattr with dht_fix_dir_xattr, which correctly resets
the un-used (after re-cal) layouts.

Maintain a list of writes (either written behind or SYNC) which are
currently "in progress" (i.e, STACK_WIND'ed towards server) and hold
off any new STACK_WIND of write (either written behind or SYNC) which
overlaps with any of the "in progress" writes.
This is a guarantee which AFR's eager-lock depends upon (though not
strictly a write-behind requirement)

Brick processes listen on all the interfaces on a given port.
When multiple glusterds run on one machine, glusterd assumes
that it 'owns' the ports on that machine. This can lead to the
different glusterd instances to step on each other's ports.
This fix ensures that brick processes listen only on the its
host IP when glusterd has bind-address option set.

fd based operations such as readv checked only for data split brain
instead of complete split-brain (i.e both data + metadata) assuming that
open would have done the complete split-brain check. However open-behind
would have unwound open, without winding to afr thus preventing the complete
split-brain check and some appliations will be able to read the contents
of the file even though the file has metadata split-brain. So let all
the fd based fops do a defensive check of complete split-brain.

This fixes the issue of task-id tests failing randomly. The condition used to
check rebalance/remove-brick was running was wrong, which could lead to the
task-id for these tasks to not be displayed even when the actual commit hadn't

* requests coming in as root are converted to nfsnobody
* with open-behind some acl checks wont happen and nfsnobody
can read the file "whose owner is root and other users do not
have permission to read the file". This is becasue open-behind
does not send the open to the brick and sends success to the
application, thus the acl related tests on the file wont happen
which would have prevented the file from being opened.

In dht_notify, we used to create a thread to start defrag
crawls after we had heard from all child subvols.
This was in-correct, as a later event, could also trigger the
crawl again(due to the fact that all subvols had responded).
The fix is to make sure, the thread is started only once after
all subvols have responded the first time

If holes are encountered, then we do not write these to the dst,
which sometimes causes file size to be lesser than src. Data is not
corrupted, as when non-zero reads are received, we do write that data.
Calling a truncrate to give file size to prevent it from being
truncated to less than src in case the file end has holes.
Thanks to Brian Foster for providing the test case

PROBLEM:
When the brick directory of a volume is absent on any of the servers,
AND an attempt is made to start the volume, commit fails ONLY on the
node where the brick dir is absent, leading to a split-brain like
situation.
FIX:
Harden 'volume start' to check for the presence of brick directories
at the time of staging, thereby preventing commit failure.

Since directories have presence on all subvolumes there is
no definite meaning of ->hashed_subvol or ->cached_subvol.
getxattr() code path chooses ->cached_subvol for pathinfo
extended attribute. While this makes sense of files, it makes
less sense for directories. Further if a hashed or a cached
subvolume is down, and there's a getxattr request for a
directory, we return with an errno.
This patch changes pathinfo extended attribute contents by
aggregating information from all subvolumes that are up.
