This fix adds support to view the number of promoted or demoted
files from the cli. The mechanism is isolmorphic to checking
the status of volumes being rebalanced.

- With this change, the xattr will represent if the file needs to be healed or
not. It will have different values for data/entry and metadata changes.
- inode ref leaks and dict_set_dynstr related leaks fixed
- Added support for trylock/lock based on heal-cmd execution or not
in data heal.
- Made fixes to pass regression runs

Data self-heal:
1) Take inode lock in domain 'this->name:self-heal' on 0-0 range (full file),
So that no other processes try to do self-heal at the same time.
2) Take inode lock in domain 'this->name' on 0-0 range (full file),
3) perform fxattrop+fstat and get the xattrs on all the bricks
3) Choose the brick with ec->fragment number of same version as source
4) Truncate sinks
5) Unlock lock taken in 2)
5) For each block take full file lock, Read from sources write to the sinks, Unlock
6) Take full file lock and see if the file is still sane copy i.e. File didn't become unusable while the bricks are offline.
Update mtime to before healing
7) xattrop with -ve values of 'dirty' and difference of highest and its own
version values for version xattr
8) unlock lock acquired in 6)
9) unlock lock acquired in 1)

Metadata self-heal:
1) Take inode lock in domain 'this->name' on 0-0 range (full file)
2) perform lookup and get the xattrs on all the bricks
3) Choose the brick with highest version as source
4) Setattr uid/gid/permissions
5) removexattr stale xattrs
6) Setxattr existing/new xattrs
7) xattrop with -ve values of 'dirty' and difference of highest and its own
version values for version xattr
8) unlock lock acquired in 1)
Entry self-heal:
1) take directory lock in domain 'this->name:self-heal' on 'NULL' to prevent
more than one self-heal
2) we take directory lock in domain 'this->name' on 'NULL'
3) Perform lookup on version, dirty and remember the values
4) unlock lock acquired in 2)
5) readdir on all the bricks and trigger name heals
6) xattrop with -ve values of 'dirty' and difference of highest and its own
version values for version xattr
7) unlock lock acquired in 1)
Name heal:
1) Take 'name' lock in 'this->name' on 'NULL'
2) Perform lookup on 'name' and get stat and xattr structures
3) Build gfid_db where for each gfid we know what subvolumes/bricks have
a file with 'name'
4) Delete all the stale files i.e. the file does not exist on more than
ec->redundancy number of bricks
5) On all the subvolumes/bricks with missing entry create 'name' with same
type,gfid,permissions etc.
6) Unlock lock acquired in 1)
Known limitation: At the moment with present design, it conservatively
preserves the 'name' in case it can not decide whether to delete it. this can
happen in the following scenario:
1) we have 3=2+1 (bricks: A, B, C) ec volume and 1 brick is down (Lets say A)
2) rename d1/f1 -> d2/f2 is performed but the rename is successful only on one
of the bricks (Lets say B)
3) Now name self-heal on d1 and d2 would re-create the file on both d1 and d2
resulting in d1/f1 and d2/f2.
Because we wanted to prevent data loss in the case above, the following
scenario is not healable, i.e. it needs manual intervention:
1) we have 3=2+1 (bricks: A, B, C) ec volume and 1 brick is down (Lets say A)
2) We have two hard links: d1/a, d2/b and another file d3/c even before the
brick went down
3) rename d3/c -> d2/b is performed
4) Now name self-heal on d2/b doesn't heal because d2/b with older gfid will
not be deleted. One could think why not delete the link if there is
more than 1 hardlink, but that leads to similar data loss issue I described
earlier:
Scenario:
1) we have 3=2+1 (bricks: A, B, C) ec volume and 1 brick is down (Lets say A)
2) We have two hard links: d1/a, d2/b
3) rename d1/a -> d3/c, d2/b -> d4/d is performed and both the operations are
successful only on one of the bricks (Lets say B)
4) Now name self-heal on the 'names' above which can happen in parallel can
decide to delete the file thinking it has 2 links but after all the
self-heals do unlinks we are left with data loss.

This change broke the build on NetBSD, FreeBSD, and MacOS X:
http://review.gluster.org/10526/
We restore the build with two fixes:
- Use POSIX-compliant sysconf(_SC_NPROCESSORS_ONLN) to get the
number of processors, instead of Linux specific get_nprocs().
That let us remove Linux-specific #include <sys/sysinfo.h>
- Only define MAX() if it is not already defined. NetBSD defines
it in <sys/param.h> which is already included

The NFS-server sets EOF only in the READ reply when op_errno is set to
ENOENT. Xlators are expected to set op_errno to ENOENT when EOF is
reached, op_ret will contain the number of bytes returned by the READ.
When an NFS-client (like VMware ESXi) do a READ that exceeds the size of
the file, errno should be set to EOF and the return value contains the
number of bytes that are read (from the requested offset, until the end
of the file). Not setting EOF on a correct short READ, can result in
errors on the NFS-client.
This is not an issue with the Linux NFS-client (or VFS). Linux is smart
enough to not try to read more bytes than the file contains.

choice.
2) If split-brain inspection/resolution is being done
from the mount for a file, ref the inode when
split-brain-choice is set.
This inode will be unconditionally unref-ed after timeout
seconds set by the user/default otherwise.
3) Updated the doc and testcase to reflect the changes.

Adding 64 bits in "version" key of extended attributes. First 64 bits (Left)
represents Data version. Last 64 bits (right) represents Meta Data version.
Note: 3.7 and 3.6 version ec can't co-exist with this change because xattrop in
3.6 will fail with ERANGE as the buffer passed to it will be '8' bytes where as
the value will be 16 bytes in 3.7. Where as 3.7 version clients can work with
old version files. For upgrades we need to tell users to complete heals and
then upgrade

If a read IO occurs against a file that has reached rebalance
phase 2, we redirect the IO to the destination. For tiered
volumes, when we try to reopen the file (on the destination),
the lower level DHT receives the open call and fails; it does
not have a "cached subvol". Fix is to "teach" the lower level
DHT of the new location by sending a locate before the open.

Background:
Glusterfs changelogs are stored in each brick, which records the changes
happened in that brick. Georep will run in all the nodes of master and
processes changelogs "independently".
Processing changelogs is in brick level, but all the fops will be replayed
on "slave mount" point.
Problem:
With a DHT volume, in changelog "internal fops" are NOT recorded.
For Rename case, Rename is recorded in "hashed" brick changelog.
(DHT's internal fops like creating linkto file, unlink is NOT recorded).
This lead us to inconsistent rename operations.
For example,
Distribute volume created with Two bricks B1, B2.
//Consider master volume mounted @ /mnt/master
and following operations executed:
cd /mnt/master
touch f1 // f1 falls on B1 Hash
mv f1 f2 // f2 falls on B2 Hash
// Here, Changelogs are recorded as below:
@B1
CREATE f1
@B2
RENAME f1 f2
Here, race exists between Brick B1 and B2, say B2 will get executed first.
Source file f1 itself is "NOT PRESENT", so it will go ahead and create
f2 (Current implementation).
We have this problem When rename falls in another brick and
file is unlinked in Master.
Similar kind of issue exists in following case too(multiple rename):
CREATE f1
RENAME f1 f2
RENAME f2 f1
Solution:
Instead of carrying out "changelogging" at "HASHED volume",
carry out at the "CACHED volume".
This way we have rename operations carried out where actual files are present.
So,Changelog recorded as :
@B1
CREATE f1
RENAME f1 f2
credit: sarumuga@redhat.com
PS: Some of the races as the one below are _NOT_ fixed by this patch
* f1 and f2 exist. B1 and B2 are their respective cached subvols. For
both files hashed-subvol == cached-subvol
* mv f1 f2 on master.
* B1 has change-log entry of rename f1 f2
* rebalance migrates f2 from B1 and B2
* mv f2 f1 on master.
* B2 has change-log entry of rename f2 f1
Since changelog entries (rename f1 f2) and (rename f2 f1) are processed
independently by gsyncds, which of either f1 and f2 survives on slave
is subject to race. Note that on master its file f1 with name f1 which
survived. On slave it can be either file f1 with name f1 or file f2
with name f2 based on who wins the race of processing changelog.

When we attach a tier, the hot tier becomes the hashed
subvolume. But directories may not yet have been replicated by
the fix layout process. Hence lookups to those directories
will fail on the hot subvolume. We should only go to the hashed
subvolume once the layout has been fixed. This is known if the
layout for the parent directory does not have an error. If
there is an error, the cold tier is considered the hashed
subvolume. The exception to this rules is ENOCON, in which
case we do not know where the file is and must abort.
Note we may revalidate a lookup for a directory even if the
inode has not yet been populated by FUSE. This case can
happen in tiering (where one tier has completed a lookup
but the other has not, in which case we revalidate one tier
when we call lookup the second time). Such inodes are
still invalid and should not be consulted for validation.

Add logic in afr to work in conjunction with the arbiter xlator when a
replica 3 arbiter volume is created. More specifically, this patch:
* Enables full locks for afr data transaction for such volumes.
* Removes the upfront marking of pending xattrs at the time of pre-op
and defer it to post-op. (This is an arbiter independent change and is made for all afr transactions.)
* After pre-op stage, check if we can proceed with the fop stage without
ending up in split-brain by examining the changelog xattrs.
* Unwinds the fop with failure if only one source was available at the
time of pre-op and the fop happened to fail on particular source brick.
* Skips data self-heal if arbiter brick is the only source available.
* Adds the arbiter-count option to the shd graph.
This patch is a part of the arbiter logic implementation for 3 way AFR
details of which can be found at http://review.gluster.org/#/c/9656/

When calling dlopen() for libgfdb, do not specify the library version
number "libgfdb.so.0.0.1", since libtool will not always create libraries
or link with that name with the full 3-digit version. For instance on
NetBSD only up to the 2-digit version is available and "libgfdb.so.0.0.1"
does not exist.
Instead, just specify "libgfdb.so" and rely on smymlinks installed by

This is a follow up patch for http://review.gluster.org/#/c/10080
In the above, the suggested change in
http://review.gluster.org/#/c/10080/7/xlators/cluster/dht/src/dht-rebalance.c
doesnot work. The reason it doesnt work is promotion and demotion are done in
a multithread way. Whenever a promotion or demotion thread is called, the frame
of the old sync_op thread is not carried with it. As a result the frame->root->pid
is not set.
Solution:
When the file is getting migrated, we get a tiering.migration key_value in the
xattr dict, so that we pass this dic key-value when we do syncop_setxattr()
to do data migration and set the frame->root->pid GF_CLIENT_PID_TIER_DEFRAG
in dht_setxattr() just before calling dht_start_rebalance_task().

problem:
1. When two threads execute in parallel in dht_getxattr_cbk
it may so happen that, both may find local->xattr to be NULL. As
a result dht_aggregate_xattr may not get executed.
2. In dht_getxattr_cbk,
thread1 thread2
T1 this_call_cnt = 2 -1
T2 this_call_cnt = 1 - 1
T3 fills local_xattr
T4 DHT_STACK_UNWIND -> local_wipe
T5 tries to dereference local
which is already freed,
leading to crash.
Solution:
for problem1: Execute critical section inside frame lock
to resolve race.
for problem2: Calculate this_call_count just before out section.

The current patch address two part of the design proposed.
1. Rebalance multiple files in parallel
2. Crawl only bricks that belong to the current node
Brief design explanation for the above two points.
1. Rebalance multiple files in parallel:
-------------------------------------
The existing rebalance engine is single threaded. Hence, introduced
multiple threads which will be running parallel to the crawler. The
current rebalance migration is converted to a "Producer-Consumer"
frame work.
Where Producer is : Crawler
Consumer is : Migrating Threads
Crawler: Crawler is the main thread. The job of the crawler is now
limited to fix-layout of each directory and add the files which are
eligible for the migration to a global queue in a round robin manner
so that we will use all the disk resources efficiently. Hence, the
crawler will not be "blocked" by migration process.
Producer: Producer will monitor the global queue. If any file is
added to this queue, it will dqueue that entry and migrate the file.
Currently 20 migration threads are spawned at the beginning of the
rebalance process. Hence, multiple file migration happens in parallel.
2. Crawl only bricks that belong to the current node:
--------------------------------------------------
As rebalance process is spawned per node, it migrates only the files
that belongs to it's own node for the sake of load balancing. But it
also reads entries from the whole cluster, which is not necessary as
readdir hits other nodes.
New Design:
As part of the new design the rebalancer decides the subvols
that are local to the rebalancer node by checking the node-uuid of
root directory prior to the crawler starts. Hence, readdir won't hit
the whole cluster as it has already the context of local subvols and
also node-uuid request for each file can be avoided. This makes the
rebalance process "more scalable".

UUID strings are UUID_CANONICAL_FORM_LEN (36) bytes long
plus the trailing nul character that various function (e.g.:
uuid_unparse) will add. As a consequence, UUID strings must
be declared as UUID_CANONICAL_FORM_LEN+1 long, otherwise
we get a off-by-one overrun that corrupts the next variable
on stack.

If the version numbers do not match, then writes are performed only on at least
N-R bricks which have same version. But if we want to do healing of files which
are constantly modified we need to allow writes on subvols that are undergoing
heal. Data healing will mark 62nd bit while the heal is going on. When the data
transaction sees that this bit is set it needs to perform the fop on that
subvol irrespective of whether the versions match or do not match. Fop is
considered successful only if N-R non-healing bricks succeed.

These commands work in a manner analagous to rebalancing when removing a
brick. The existing migration daemon detects "detach start" and switches
to moving data off the hot tier. While in this state all lookups are
directed to the cold tier.

Problem:
gf_deitransform returns the glbal client-id in the complete graph. So except
for the first disperse subvolume under dht, all the other disperse subvolumes
will return a client-id greater than ec->nodes, so readdir will always error
out in those subvolumes.
Fix:
Get the client subvolume whose client-id matches the client-id returned by
gf_deitransform of offset.

This patch adds support for xdata in both the
request and response path of syncops.
Few calls like lookup already had the support;
have renamed variables in few places to maintain
uniformity.
xdata passed downwards is known as xdata_in
and xdata passed upwards is known as xdata_out.
There is an old patch by Jeff Darcy at
http://review.gluster.org/#/c/8769/3 which does the
same for some selected calls. It also brings in
xdata support at gfapi level.
xdata support at gfapi level would be introduced
in subsequent patches.

This fix will solve the heating of the files during the promotion
or demotion.
Promotion:
~~~~~~~~~
When a file gets promoted it get the current time stamp
during creation only, but following writes or reads during the
migration wont heat the file.
Demotion:
~~~~~~~~
When a file gets demoted it get the wind/unwind time stamp is set to
zero. The following writes or reads during the migration wont heat
the file.
What is remaining ?
~~~~~~~~~~~~~~~~~
Bug 1209129 ( https://bugzilla.redhat.com/show_bug.cgi?id=1209129 )
Inspite of this fix there is still a issue remaining, i.e the heat of
the file is not keep intact during a internal rebalance activity i.e
a rebalance within a tier.

1. Expected behavior of get_real_filename feature.
A getxattr on a existing dir with glusterfs.get_real_filename:<filename>
as key should result in one of the following things.
a. A value returned for that key having the real filename (a file whose
match is a case insensitive match to the filename passed in key).
b. op_ret = -1 and errno set to ENOENT meaning that no such file exists
under the specified dir in any case.
c. op_ret = -1 and errno set to ENODATA. This is a case assuming no
xlator interprets the glusterfs.get_real_filename key and it get
passed down to the posix xlator. Naturally, posix xlator would not
find any xattr with this key and would return ENODATA. This will be
interpreted specially by the caller as the feature not being supported
by underlying glusterfs.
2. What assumptions are wrong?
Initially the key used to be user.glusterfs.get_real_filename.
In that case, when posix xlator did a getxattr call it would have
received ENODATA as error. However, the key has now changed to
glusterfs.get_real_filename. This leads to a EOPNOTSUPP error instead.
Considering the above information, this is a rewrite of
get_real_filename logic in dht.

There is smoke test failure due to implici declaration of function
"uuid_parse" and "uuid_compare".
Fix is to change these function caller name to "gf_uuid_parse" and
"gf_uuid_compare."
