GF_CONTENT_KEY aggregation requires that the fragments on the bricks belong to
same data i.e. no operations are modifying the content while lookup is
performed on it. The only way to know it is to get at least ec->fragments+1
number of responses and see that two different sets of ec->fragments number of
fragments give same data. But at the moment we feel that this slows down
ec-lookup. So removing handling of this for now.

Problem:
1) ec_access/ec_readlink_/ec_readdir[p] _cbks are trying to recover only from
ENOTCONN.
2) When the fop succeeds it unwinds right away. But when its
ec_fop_manager resumes, if the number of bricks that are up is less than
ec->fragments, the the state machine will resume with -EC_STATE_REPORT which
unwinds again. This will lead to crashes.
Fix:
- If fop fails retry on other subvols, as ESTALE/ENOENT/EBADFD etc are also
recoverable.
- unwind success/failure in _cbks

Problem:
ec_update_size_version expects all the keys it did xattrop with to come in
response so that it can set the values again in ec_update_size_version_done.
But EC_XATTR_DIRTY is not combined so the value won't be present in the
response. So ctx->post/pre_dirty are not updated in
ec_update_size_version_done. So these values are still non-zero. When
ec_unlock_now is called as part of flush's unlock phase it again tries to
perform same xattrop for EC_XATTR_DIRTY. But ec_update_size_version is not
expected to be called in unlock phase of flush because ec_flush_size_version
should have reset everything to zero and unlock is never invoked from
ec_update_size_version_done for flush/fsync/fsyncdir. This leads to stale lock
which leads to hang.
Fix:
EC_XATTR_DIRTY is removed in ex_xattrop_cbk and is never combined with other
answers. So remove handling of this in the response.

A previous patch (http://review.gluster.org/10974) introduced a
bug that caused that some metadata differences could not be
detected in some circumstances. This could cause that self-heal
is not triggered and the file not repaired.
We also need to consider all differences for lookup requests, even
if there isn't any lock. Special handling of differences in lookup
is already done in lookup specific code.

When ec combines iatt structures from multiple bricks, it checks
for equality in important fields. This is ok for iatt related to
inodes involved in the operation that have been locked before
starting execution. However some fops return iatt information
from other inodes. For example a rename locks source and destination
parent directories, but it also returns an iatt from the entry
itself.
In these cases we ignore differences in some fields to avoid false
detection of inconsistencies and trigger unnecessary self-heals.
Another issue is solved in this patch that caused that the real
size of the file stored into the inode context was lost during
self-heal.

If a file is under migration, any xattrs created on it
are lost post migration of the file. This is because
the xattrs are set only on the cached subvol of the source
and as the source is under migration, it becomes a linkto file
post migration.

EC uses an eager lock mechanism to optimize multiple read/write
requests on the same entry or inode. This increases performance
but can have adverse results when other clients try to access the
same entry/inode.
To solve this, this patch adds a functionality to detect when this
happens and force an earlier release to not block other clients.
The method consists on requesting GF_GLUSTERFS_INODELK_COUNT and
GF_GLUSTERFS_ENTRYLK_COUNT for all fops that take a lock. When this
count is greater than one, the lock is marked to be released. All
fops already waiting for this lock will be executed normally before
releasing the lock, but new requests that also require it will be
blocked and restarted after the lock has been released and reacquired
again.
Another problem was that some operations did correctly lock the
parent of an entry when needed, but got the size and version xattrs
from the entry instead of the parent.
This patch solves this problem by binding all queries of size and
version to each lock and replacing all entrylk calls by inodelk ones
to remove concurrent updates on directory metadata. This also allows
rename to correctly update source and destination directories.

ec_heal creates ec_fop_data but doesn't run ec_manager. ec_fop_data_allocate
adds this fop to ec->pending_fops, because ec_manager is not run on this heal
fop it is never removed from ec->pending_fops. When it is accessed after free
it leads to crash. It is better to not to add HEAL fops to ec->pending_fops
because we don't want graph switch to hang the mount because of a BIG
file/directory heal.

When a blocking lock is requested, lock request is succeeded even when
ec->fragment number of locks are acquired successfully in non-blocking locking
phase. This will lead to fop succeeding only on the bricks where the locks are
acquired, leading to the necessity of self-heals. To prevent these un-necessary
self-heals, if the remaining locks fail with EAGAIN in non-blocking lock phase
try blocking locking phase instead.

When a file does not exist on a brick but it does on others, there
could be problems trying to access it because there was some loc_t
structures with null 'pargfid' but 'name' was set. This forced
inode resolution based on <pargfid>/name instead of <gfid> which
would be the correct one. To solve this problem, 'name' is always
set to NULL when 'pargfid' is not present.
Another problem was caused by an incorrect management of errors
while doing incremental locking. The only allowed error during an
incremental locking was ENOTCONN, but missing files on a brick can
be returned as ESTALE. This caused an EIO on the operation.
This patch doesn't care of errors during an incremental locking. At
the end of the operation it will check if there are enough successfully
locked bricks to continue or not.

- 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)

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.

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 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.

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.

glusterfs relies on Linux uuid implementation, which
API is incompatible with most other systems's uuid. As
a result, libglusterfs has to embed contrib/uuid,
which is the Linux implementation, on non Linux systems.
This implementation is incompatible with systtem's
built in, but the symbols have the same names.
Usually this is not a problem because when we link
with -lglusterfs, libc's symbols are trumped. However
there is a problem when a program not linked with
-lglusterfs will dlopen() glusterfs component. In
such a case, libc's uuid implementation is already
loaded in the calling program, and it will be used
instead of libglusterfs's implementation, causing
crashes.
A possible workaround is to use pre-load libglusterfs
in the calling program (using LD_PRELOAD on NetBSD for
instance), but such a mechanism is not portable, nor
is it flexible. A much better approach is to rename
libglusterfs's uuid_* functions to gf_uuid_* to avoid
any possible conflict. This is what this change attempts.

position in the graph rather than relative (local) to a particular
translator.
Encoding the volume in this way allows a single translator to manage
which brick is currently being scanned for directory entries. Using a
single translator minimizes allocated bits in the d_off. It also allows
multiple DHT translators in the same graph to have a common frame of
reference (the graph position) for which brick is being read. Multiple
DHT translators are needed for the Tiering feature.
The fix builds off a previous change (9332) which removed subvolume
encoding from AFR. The fix makes an equivalent change to the EC
translator.
More background can be found in fix 9332 and gluster-dev discussions [1].
DHT and AFR/EC are responsibile (as before) for choosing which brick to
enumerate directory entries in over the readdir lifecycle.
The client translator receiving the readdir fop encodes the dht_t. It
is referred to as the "leaf node" in the graph and corresponds to the
brick being scanned.
When DHT decodes the d_off, it translates the leaf node to a local
subvolume, which represents the next node in the graph leading to
the brick.
Tracking of leaf nodes is done in common utility functions. Leaf nodes
counts and positional information are updated on a graph switch.

This patch introduces the changes required in ec xlator to handle
index/full heal.
Index healer threads:
Ec xlator start an index healer thread per local brick. This thread keeps
waking up every minute to check if there are any files to be healed based on
the indices kept in index directory. Whenever child_up event comes, then also
this index healer thread wakes up and crawls the indices and triggers heal.
When self-heal-daemon is disabled on this particular volume then the healer
thread keeps waiting until it is enabled again to perform heals.
Full healer threads:
Ec xlator starts a full healer thread for the local subvolume provided by
glusterd to perform full crawl on the directory hierarchy to perform heals.
Once the crawl completes the thread exits if no more full heals are issued.
Changed xl-op prefix GF_AFR_OP to GF_SHD_OP to make it more generic.
