There is a possibility that 'frame' could have been
destroyed in dht_selfheal_dir_setattr() which can
lead to local->mds_heal_fresh_lookup showing junk
non-zero number. That will lead to double
STACK_DESTROY. Remembered the value of the variable
before the call to fix the access.

Problem: Selfheal as part of directory does not return an error if
the layout setxattr fails. This is because the actual lookup fop
must have been successful to proceed for layout heal. Hence, we could
not tell if fix-layout failed in rebalance.
Solution: We can check this information in the layout structure that
whether all the xlators have returned error.

This patch is removing some of the "tier" code in dht xlator, as it is no longer
being used.
Not all of the not-needed code is removed at once, so reviewing is easier.
Follow up patches removing additional unused code will follow.
This is based in the work done in https://review.gluster.org/#/c/glusterfs/+/23935/

When bringing back a downed brick and performing lookup from the client
side, the permission on said brick aren't updated on the first lookup,
but only on the second.
This patch modifies permission update logic so the first lookup will
trigger a permission update on the downed brick.
LIMITATIONS OF THE PATCH:
As the choice of source depends on whether the directory has layout or not.
Even the directories on the newly added brick will have layout xattr[zeroed], but the same is not true for a root directory.
Hence, in case in the entire cluster only the newly added bricks are up [and others are down], then any change in permission during this time will be overwritten by the older permissions when the cluster is restarted.

Problem: With lookup-optimize set to on by default, a client with
stale-layout can create a new file on a wrong subvol. This will lead to
possible duplicate files if two different clients attempt to create the
same file with two different layouts.
Solution: Send in-memory layout to be cross checked at posix before
commiting a "create". In case of a mismatch, sync the client layout with
that of the server and attempt the create fop one more time.
test: Manual, testcase(attached)

problem: Geo-rep gsyncd process mounts the master and slave volume
on master nodes and slave nodes respectively and starts
the sync. But it doesn't wait for the mount to be in ready
state to accept I/O. The gluster mount is considered to be
ready when all the distribute sub-volumes is up. If the all
the distribute subvolumes are not up, it can cause ENOTCONN
error, when lookup on file comes and file is on the subvol
that is down.
solution: Added a Virtual Xattr "dht.subvol.status" which returns "1"
if all subvols are up and "0" if all subvols are not up.
Geo-rep then uses this virtual xattr after a fresh mount, to
check whether all subvols are up or not and then starts the
I/O.

Problem : When a file is migrated, dht attempts to re-open all open
fds on the new cached subvol. Earlier, if dht had not opened the fd,
the client xlator would be unable to find the remote fd and would
fall back to using an anon fd for the fop. That behavior changed with
https://review.gluster.org/#/c/glusterfs/+/15804, causing fops to fail
with EBADFD if the fd was not available on the cached subvol.
The client xlator returns EBADFD if the remote fd is not found but
dht only checks for EBADF before re-opening fds on the new cached subvol.
Solution: Handle EBADFD at dht code path to avoid the issue

In many places we use it, compare to it, etc. It could be a static variable,
as it really doesn't change. I think it's better than initializing to 0
and then doing gfid[15] = 1 or other tricks.
I think there are additional oppportunuties to make more variables static.
This is an attempt at an easy one.

After add-brick and rebalance, the ctime xattr is not present
on rebalanced directories on new brick. This patch fixes the
same.
Note that ctime still doesn't support consistent time across
distribute sub-volume.
This patch also fixes the in-memory inconsistency of time attributes
when metadata is self healed.

There are two ways to fetch node-uuid information from dht.
1 - #define GF_XATTR_LIST_NODE_UUIDS_KEY "trusted.glusterfs.list-node-uuids"
This key is used by AFR.
2 - #define GF_REBAL_FIND_LOCAL_SUBVOL "glusterfs.find-local-subvol"
This key is used for non-afr volume type.
We do two getxattr operations. First on the #1 key followed by on #2 if
getxattr on #1 key fails.
Since the parent function "dht_init_local_subvols_and_nodeuuids" logs failure,
moving the log-level to DEBUG in dht_find_local_subvol_cbk.

get_real_filename is implemented as a virtual extended attribute to help
Samba implement the case-insensitive but case preserving SMB protocol
more efficiently. It is implemented as a getxattr call on the parent directory
with the virtual key of "get_real_filename:<entryname>" by looking for a
spelling with different case for the provided file/dir name (<entryname>)
and returning this correct spelling as a result if the entry is found.
Originally (05aaec645a6262d431486eb5ac7cd702646cfcfb), the
implementation used the ENOENT errno to return the authoritative answer
that <entryname> does not exist in any case folding.
Now this implementation is actually a violation or misuse of the defined
API for the getxattr call which returns ENOENT for the case that the dir
that the call is made against does not exist and ENOATTR (or the synonym
ENODATA) for the case that the xattr does not exist.
This was not a problem until the gluster fuse-bridge was changed
to do map ENOENT to ESTALE in 59629f1da9dca670d5dcc6425f7f89b3e96b46bf,
after which we the getxattr call for get_real_filename returned an
ESTALE instead of ENOENT breaking the expectation in Samba.
It is an independent problem that ESTALE should not leak out to user
space but is intended to trigger retries between fuse and gluster.
But nevertheless, the semantics seem to be incorrect here and should
be changed.
This patch changes the implementation of the get_real_filename virtual
xattr to correctly return ENOATTR instead of ENOENT if the file/directory
being looked up is not found.
The Samba glusterfs_fuse vfs module which takes advantage of the
get_real_filename over a fuse mount will receive a corresponding change
to map ENOATTR to ENOENT. Without this change, it will still work
correctly, but the performance optimization for nonexisting files is
lost. On the other hand side, this change removes the distinction
between the old not-implemented case and the implemented case.
So Samba changed to treat ENOATTR like ENOENT will not work correctly
any more against old servers that don't implement get_real_filename.
I.e. existing files will be reported as non-existing

There are many include statements that are not needed.
A previous more ambitious attempt failed because of *BSD plafrom
(see https://review.gluster.org/#/c/glusterfs/+/21929/ )
Now trying a more conservative reduction.
It does not solve all circular deps that we have, but it
does reduce some of them. There is just too much to handle
reasonably (dht-common.h includes dht-lock.h which includes
dht-common.h ...), but it does reduce the overall number of lines
of include we need to look at in the future to understand and fix
the mess later one.

If parallel-readdir is enabled, the rda xlator is loaded
below dht in the graph and proactively lists and caches
entries when an opendir is performed. dht_rmdir checks if
the directory being deleted contains stale linkto files by
performing a readdirp on its child subvols. However, as
the entries are actually read in during the opendir operation
which does not request the linkto xattr,no linkto xattrs are
present for the entries causing dht to incorrectly identify
them as data files and fail the rmdir operation with ENOTEMPTY.
DHT now always adds the linkto xattr in the list of xattrs
requested in the opendir.

Fuse sets a random gfid-req value for a fresh lookup. Posix
lookup will set this gfid on entries with missing gfids causing
a GFID mismatch for directories.
DHT will now ignore the Fuse provided gfid-req and use the GFID

Mostly, unlock before logging.
In some cases, moved different code that was not needed
to be under lock (for example, taking time, or malloc'ing)
to be executed before taking the lock.
Note: logging might be slightly less accurate in order, since it may
not be done now under the lock, so order of logs is racy. I think
it's a reasonable compromise.
Compile-tested only!

libglusterfs devel package headers are referenced in code using
include semantics for a program, this while it works can be better
especially when dealing with out of tree xlator builds or in
general out of tree devel package usage.
Towards this, the following changes are done,
- moved all devel headers under a glusterfs directory
- Included these headers using system header notation <> in all
code outside of libglusterfs
- Included these headers using own program notation "" within
libglusterfs
This change although big, is just moving around the headers and
making it correct when including these headers from other sources.
This helps us correctly include libglusterfs includes without
namespace conflicts.

If a single brick is added to the volume and the
newly added brick is the first to respond to a
dht_revalidate call, its stbuf will not be merged
into local->stbuf as the brick does not yet have
a layout. The is_permission_different check therefore
fails to detect that an attr heal is required as it
only considers the stbuf values from existing bricks.
To fix this, merge all stbuf values into local->stbuf
and use local->prebuf to store the correct directory
attributes.

If unlinking of an invalid linkto file failed in lookup-everywhere
codepath, lookup was failed with EIO. The rational as per the comment
was,
<snip>
/* When dht_lookup_everywhere is performed, one cached
*and one hashed file was found and hashed file does
*not point to the above mentioned cached node. So it
*was considered as stale and an unlink was performed.
*But unlink fails. So may be rebalance is in progress.
*now ideally we have two data-files. One obtained during
*lookup_everywhere and one where unlink-failed. So
*at this point in time we cannot decide which one to

*as cached node, application will fail. So return EIO.
*/
</snip>
However, this reasoning is only valid when
* op_errno is EBUSY, indicating rebalance is in progress
* op_errno is ENOTCONN as wecannot determine what was the status of
file on brick.
Hence this patch doesn't fail lookup unless unlink fails with an
either EBUSY or ENOTCONN

When compiling in other architectures there appear many warnings. Some
of them are actual problems that prevent gluster to work correctly on
those architectures.

Also fixes the issue caused due to not converting back the fn function
to after getting its address. We wanted the value of the field, not
the address of the pt_fop field.
With this patch, DHT will always be started in pass-through
mode if the number of subvols is just 1.
Fixes some tests to make sure DHT is in full config (ie, subvols > 1).
- increased timeout of brick-mux test as it was bordering on 300 seconds.
- Also change the volume type to supported 'replica 3' from 'replica 2'.
- also no DHT tests should assume presence of DHT when there is
just 1 brick in volume

Using the dht_filter_loc_subvol_key to create
files on specific subvols did not create a linkto
file. This can make the file inaccessible as
lookup-optimize is now enabled by default.

The earlier implementation required the file to already exist
when trying to get the hashed subvol. The reworked implementation
allows a user to get the hashed subvol for any filename, whether
it exists or not.
Usage: getfattr -n "dht.file.hashed-subvol.<filename>" <parent dir>
Eg:To get the hashed subvol for file-1 inside dir-1
getfattr -n "dht.file.hashed-subvol.file-1" /mnt/gluster/dir1

GF_CALLOC() when
It doesn't make sense to calloc (allocate and clear) memory
when the code right away fills that memory with data.
It may be optimized by the compiler, or have a microscopic
performance improvement.
Please review carefully, especially for string allocation, with the
terminating NULL string (added another byte to ensure it's there).
Only compile-tested!

strncpy may not be very efficient for short strings copied into
a large buffer: If the length of src is less than n,
strncpy() writes additional null bytes to dest to ensure
that a total of n bytes are written.
Instead, use snprintf().
Also:
- save the result of strlen() and re-use it when possible.
- move from strlen to SLEN (sizeof() ) for const strings.
Compile-tested only!

It doesn't make sense to calloc (allocate and clear) memory
when the code right away fills that memory with data.
It may be optimized by the compiler, or have a microscopic
performance improvement.
In some cases, also changed allocation size to be sizeof some
struct or type instead of a pointer - easier to read.
In some cases, removed redundant strlen() calls by saving the result
into a variable.
1. Only done for the straightforward cases. There's room for improvement.
2. Please review carefully, especially for string allocation, with the
terminating NULL string.
Only compile-tested!
