Please review, it's not always just the comments that were fixed.
I've had to revert of course all calls to creat() that were changed
to create() ...

Only compile-tested!

2017-12-08T22:33:20+00:00

Export items are used in the auth cache and need to be reference
counted to avoid use-after free bugs.

nfs: allow hostnames with dashes in exports/netgroups files

2016-06-28T20:29:13+00:00

Hostnames with dashes (like "vagrant-testVM") are not correctly parsed
when reading the exports/netgroups files. This bacomes obvious when
running ./run-tests-in-vagrant.sh because it causes
tests/basic/mount-nfs-auth.t and tests/basic/netgroup_parsing.t to fail.

The regex for hostname (in exports) and the entry and hostname
(netgroups) parsing does not include the "-" sign, and hence the
hostnames are splitted at it.

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.

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: add support for separate 'exports' file

2015-03-15T07:45:50+00:00

The Linux kernel NFS server uses /etc/exports to manage permissions for
the NFS-clients. Extending the Gluster/NFS server to support a similar
scheme is needed for many deployments in enterprise environments.
