<title>storage/posix: Don't allow gfid/volume-id xattr to be removed</title>

<id>11eb8ba870457337c6067284dde4277e09764c0a</id>
<content type='text'>
Problem:
Bulk xattr removal doesn't check if the xattrs that are coming in xdata
have gfid/volume-id xattrs, so there is potential for bulkremovexattr
removing gfid/volume-id.
I also observed that bulkremovexattr is not available for fremovexattr.

Fix:
Do proper checks in bulk removexattr to remove gfid/volume-id.
Refactor [f]removexattr to reduce the differences.

Problem: sometime brick process is getting crash after stop the volume
         while brick mux is enabled and no. of volumes are high

Solution: In posix notify at the time close mount_lock dir , dir handle
          needs to set NULL to avoid the reuse of same dir handle.

<title>cluster/ec: Get size of file in EC [f]xattrop</title>

Problem:
For allowing parallel writes we shouldn't depend on ia_size to be same for
all the bricks in each write_cbk(). But we need to make sure backend size
is correct on all the bricks and no crashes/manual modifications happened.

Fix:
At the time of get_size_version() we do 1 check to make sure size of the file
is same across the bricks. From then on the FOPs will give the status of the
fop, so we rely on this information to keep which bricks are good/bad.

Updates #251

With this infra, a new xattr is stored on each entry
creation as below.

trusted.gfid2path.&lt;xxhash&gt; = &lt;pargfid&gt;/&lt;basename&gt;

If there are hardlinks, multiple xattrs would be present.

Fops which are impacted:
create, mknod, link, symlink, rename, unlink

Option to enable:
gluster vol set &lt;VOLNAME&gt; storage.gfid2path on

<title>posix: Avoid one extra call of l(get|list)xattr call after use buffer in posix_getxattr</title>

Problem: In posix xlator posix_(f)getxattr is calling system call(sys_lgetxattr)
         two times to fetch the xattr value.

Solution: After use the extra buffer for first time calling we can avoid second
          attempt of system call(sys_lgetxattr) calling in posix_getxattr for most
          of the xattrs.

<title>dht/hardlink : Remove stale linkto file incase of failure</title>

<id>237648780336d41cd6d820c337b38dd13f4d9e72</id>
<content type='text'>
This is a similar issue fixed for rename in https://review.gluster.org/#/c/16016/
For hardlinks, if cached and hashed subvolumes are different, then it will first
create linkto file in hashed using root permission, but actually hardlink creation
fails with EACESS and stale linkto file is never removed.All the followup hardlink
calls with file name will result ESTALE because linktofile creation fails with EEXIST
and follow up lookup on linkto file returns gfid-mismatching(old linkto file) and
finally fails with ESTALE

Steps to produce :
(From link/00.t test from posix-testsuite)
Steps executed in script
 * create a file "abc" using root
 * change the ownership of file to a non root user
 * create hardlink "link" for "abc" using a non root user, it fails with EACESS
 * delete "abc"
 * create directory "abc" using root
 * again try to create hadrlink "link" for "abc" using non root user, fails with ESTALE

Also tried to fix other bugs in dht_linkfile_create_cbk() and posix_lookup.

Thanks Susant for the help in debugging the issue and suggestion for this patch.
