glusterd: Use volume op-versions during volgen

2013-09-13T19:11:35+00:00

  Backport of '3af61d6 glusterd: Use volume op-versions during volgen'
  from master

Instead of using the cluster op-version, volume op-version is used to
enable open-behind during volgen. For doing this, the volume op-versions
are updated before regenerating the volfiles.

glusterd-volgen: Improve volume op-versions calculation

2013-06-05T12:27:10+00:00

Backport of patch on master branch, under review at
        http://review.gluster.org/4952

Volume op-versions calculations now take into account if an option,
 a. enables/disables an xlator, or
 b. is a boolean option.

This prevents op-versions from being updated when a feature is disabled.

glusterd-volgen: Enable open-behind based on op-version

2013-06-05T12:26:55+00:00

Backport of patch on master branch, under review at
        http://review.gluster.org/4866

This patch enables the open-behind by default only when the op-version
allows it. Also the volume op-version calculations take account of this
enablement.

glusterd: Introduce volume op-versions

2013-06-05T12:24:59+00:00

This is a backport of change
        9153855 glusterd: Introduce volume op-versions
from master.

Each volume is now associated with two op-versions,
 * op_version - the op-version of the highest op-versioned feature enabled
 * client_op_version - the op-version of the highest op-versioned feature
   enabled which affects the clients only.

These two op-versions are generated dynamically and kept updated during
runtime. Glusterd now uses the respective volumes' client-op-version during
getspec requests.

To achieve the above a new field in the vme table is introduced,
client_option, this boolean field tells if the option is a client side
option.

volgen: Use bind-address option for bricks when option set on glusterd

2013-03-07T06:05:38+00:00

Brick processes listen on all the interfaces on a given port.
When multiple glusterds run on one machine, glusterd assumes
that it 'owns' the ports on that machine. This can lead to the
different glusterd instances to step on each other's ports.
This fix ensures that brick processes listen only on the its
host IP when glusterd has bind-address option set.

rpc: bring in root-squashing behavior in rpc

2013-03-05T07:44:04+00:00

* requests coming in as root are converted to nfsnobody

* with open-behind some acl checks wont happen and nfsnobody
  can read the file "whose owner is root and other users do not
  have permission to read the file". This is becasue open-behind
  does not send the open to the brick and sends success to the
  application, thus the acl related tests on the file wont happen
  which would have prevented the file from being opened.

open-behind: translator to perform open calls in background

2013-02-06T21:16:08+00:00

This is functionality peeled out of quick-read into a separate
translator.

Fops which modify the file (where it is required to perform the
operation on the true fd) will trigger and wait for the backend
open to succeed and use that fd.

Fops like fstat() readv() etc. will use anonymous FD (configurable)
when original fd is unopened at the backend.

glusterd: log changes in volume create and delete codepath

2013-02-05T03:21:59+00:00

Making log changes involving two commands as they both share sections
of code (like the part where the volume metadata is cleaned up in vol
delete in case of success; and in vol create in case of failure).

* Most of the changes are of the 's/THIS/this' kind.

* Changed some of the log messages to give as much information as
  available in case of failure.

* Changed log levels in some of the log messages.
