fuse: accept the -s option to allow automounting

2016-07-03T11:17:23+00:00

autofs passes the -s option when mounting. All /sbin/mount. helpers
accept this, except mount.glusterfs. Because the helper fails when -s is
passed accessing the mountpoint through autofs gives the following
error:

  $ ls /lan/storage.lan.example.net/repos
  ls: cannot open directory /lan/storage.lan.example.net/repos: Too many levels of symbolic links

dht: add "nuke" functionality for efficient server-side deletion

2016-04-26T08:21:47+00:00

This is a backport of the following two patches (of which the second is a
trivial adjustment to a timeout for a test added by the first).

	http://review.gluster.org/13878
	http://review.gluster.org/13935

This turns a special xattr into an rmdir with flags set.  When that hits
the posix translator on the server side, that causes the file/directory
to be moved into the special "landfill" directory.  From there, the
posix janitor thread will take care of deleting it entirely on the
server side - traversing it recursively if necessary.  A couple of
secondary issues were fixed to make this effective.

 * FUSE now ensures that setxattr values are NUL terminated.

 * The janitor thread now gets woken up immediately when something is
   placed in 'landfill' instead of only when file descriptors need to be
   closed.

 * The default landfill-emptying interval was reduced to 10s.

To use the feature, issue a setxattr something like this:

   setfattr -n glusterfs.dht.nuke -v "" /mnt/glusterfs/vol/some_dir

The value doesn't actually matter; the mere receipt of a request with
this key is sufficient.  Some day it might be useful to allow setting a
required value as a sort of password, so that only those who know it can
access the underlying special functionality.

mount/fuse: report ESTALE as ENOENT

2016-04-21T02:56:11+00:00

When the inode/gfid is missing, brick report back as an ESTALE
error. However, most of the applications don't accept ESTALE as an
error for a file-system object missing, changing their behaviour.

For eg., rm -rf ignores ENOENT errors during unlink of
files/directories. But with ESTALE error it doesn't send rmdir on a
directory if unlink had failed with ESTALE for any of the files or
directories within it.

Revert "glusterd: Bug fixes for IPv6 support"

2016-04-16T02:18:23+00:00

This reverts commit b33f3c95ec9c8112e6677e09cea05c4c462040d0.

This commit exposes some issues with management encryption that prevents
GlusterFS from operating properly. This will be added again once
problems with management encryption are fixed.

glusterd: Bug fixes for IPv6 support

2016-03-21T17:52:50+00:00

Backport of http://review.gluster.org/#/c/11988/

Problem:
Glusterd not working using ipv6 transport. The idea is with proper glusterd.vol configuration,
1. glusterd needs to listen on default port (240007) as IPv6 TCP listner.
2. Volume creation/deletion/mounting/add-bricks/delete-bricks/peer-probe
needs to work using ipv6 addresses.
3. Bricks needs to listen on ipv6 addresses.
All the above functionality is needed to say that glusterd supports ipv6 transport and this is broken.

Fix:
When "option transport.address-family inet6" option is present in glusterd.vol
file, it is made sure that glusterd creates listeners using ipv6 sockets only and also the same information is saved
inside brick volume files used by glusterfsd brick process when they are starting.

Tests Run:
Regression tests using ./run-tests.sh
IPv4: Regression tests using ./run-tests.sh for release-3.7 branch verified by comparing with clean repo.
IPv6: (Need to add the above mentioned config and also add an entry for "hostname ::1" in /etc/hosts)
    Started failing at ./tests/basic/glusterd/arbiter-volume-probe.t and ran successfully till here

mount/fuse: cleanup an additional inode_ref()

2016-03-17T20:05:20+00:00

commit ca515db0127 introduced a check in
fuse_resolve_inode_simple(). This results in an additional
ref being held on inodes which were obtained through readdirp.
As a result, the inode table keeps growing and entries remain in
the active list even after deletion of such inodes from the volume.

fuse: Add a new mount option capability

2016-03-10T03:09:43+00:00

Originally all security.* xattrs were forbidden if selinux is disabled,
which was causing Samba's acl_xattr module to not work, as it would
store the NTACL in security.NTACL. To fix this http://review.gluster.org/#/c/12826/
was sent, which forbid only security.selinux. This opened up a getxattr
call on security.capability before every write fop and others.

Capabilities can be used without selinux, hence if selinux is disabled,
security.capability cannot be forbidden. Hence adding a new mount
option called capability.

Only when "--capability" or "--selinux" mount option is used,
security.capability is sent to the brick, else it is forbidden.

no-mtab (-n) mount option ignore next mount option

2016-03-08T19:09:28+00:00

The -n option does not take any arguments. It seems like this shift is
removing the next option. On my CentOS 7 system, automount calls
mount.glusterfs with the parameters:
 host:/volume /mountpoint -n -o rw,acl,_netdev
This causes the -o option to be siliently ignored.

fuse: send lookup if inode_ctx is not set

During resolving of an entry or inode, if inode ctx
was not set, we will send a lookup.

This patch also make sure that inode_ctx will be created
after every inode_link
