build: make contrib/uuid dependency optional

2015-04-10T11:39:52+00:00

On Linux systems we should use the libuuid from the distribution and not
bundle and statically link the contrib/uuid/ bits.

libglusterfs/src/compat-uuid.h has been introduced and should become an
abstraction layer for different UUID APIs. Non-Linux operating systems
should implement their compatibility layer there.

Once all operating systems have an implementation in compat-uuid.h, we
can remove contrib/uuid/ from the repository completely.

Avoid conflict between contrib/uuid and system uuid

2015-04-04T17:48:35+00:00

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.

nfs: do not fail to start when optional RPC-programs fail to register

2015-03-26T10:05:56+00:00

Some RPC-programs are not strictly required for the NFS-server. When
these optional protocols fail to get registered at the portmapper, there
is no need to fail the starting of the NFS-server.

Required RPC-programs:
 - NFS
 - MNT

Optional RPC-programs:
 - NLM
 - ACL

glusterfsd: add "print-netgroups" and "print-exports" command

2015-03-19T05:16:34+00:00

NFS now has the ability to use a separate file for "netgroups" and
"exports". An administrator should have the ability to check the
validity of the files before applying the configuration.

The "glusterfsd" command now has the following additional arguments that
can be used to check the configuration:

   --print-netgroups: Validate the netgroups file and print it out
   --print-exports: Validate the exports file and print it out

NFS-Ganesha: Volume set option for managing NFS-Ganesha exports.

2015-03-18T08:53:22+00:00

A dummy translator has been introduced as a place
holder for functions related to managing NFS-Ganesha
exports. A volume set option is introduced to
manage volume level exports.

gluster vol set  ganesha.enable ON/OFF

1. gluster volume set  ganesha.enable ON

It creates the export config file with a unique export ID.
Sends a DBus signal to export this volume dynamically.

2. gluster vol set  ganesha.enable OFF

Unexports the specific volume. Deletes the specfic
config file related to the volume.

This change also removes the handling of the older
keys "nfs-ganesha.enable" and "nfs-ganesha.host"
