nfs: add permission checking for mounting over WebNFS

2017-07-09T09:14:22+00:00

Solaris 10 uses WebNFS and not the MOUNT protocol. All permission checks
for allowing/denying clients to mount are done through the MNT handlers.
These handlers will not give out a filehandle to the NFS-client when
mounting is denied. This prevents clients from successful mounting.
However, over WebNFS a well known 'root-filehandle' is used directly
with the NFSv3 protocol.

When WebNFS was used, no permission checks (the "nfs.export-dir" option)
were applied. Now the WebNFS mount-handler in Gluster/NFS calls the
mnt3_parse_dir_exports() function that takes care of the permission
checking.

build: do not #include "config.h" in each file

2015-05-29T12:43:17+00:00

Instead of including config.h in each file, and have the additional
config.h included from the compiler commandline (-include option).

When a .c file tests for a certain #define, and config.h was not
included, incorrect assumtions were made. With this change, it can not
happen again.

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.

gNFS: Export / Netgroup authentication on Gluster NFS mount

2015-03-15T14:01:38+00:00

* Parses linux style export file/netgroups file into a structure that
  can be lookedup.

* This parser turns each line into a structure called an "export
  directory". Each of these has a dictionary of hosts and netgroups
  which can be looked up during the mount authentication process.
  (See Change-Id Ic060aac and I7e6aa6bc)

* A string beginning withan '@' is treated as a netgroup and a string
  beginning without an @ is a host.
  (See Change-Id Ie04800d)

* This parser does not currently support all the options in the man page
  ('man exports'), but we can easily add them.

nfs: more fine grained authentication for the MOUNT protocol

2015-03-15T08:37:22+00:00

The /etc/exports format for NFS-exports (see Change-Id I7e6aa6b) allows
a more fine grained control over the authentication. This change adds
the functions and structures that will be used in by Change-Id I181e8c1.

gNFS: Fix multi-homed m/c issue in NFS subdir auth

2014-06-25T07:41:52+00:00

NFS subdir authentication doesn't correctly handle multi-homed
(host with multiple NIC having multiple IP addr) OR multi-protocol
(IPv4 and IPv6) network addresses.

When user/admin sets HOSTNAME in gluster CLI for NFS subdir auth,
mnt3_verify_auth() routine does not iterate over all the resolved
n/w addrs returned by getaddrinfo() n/w API. Instead, it just tests
with the one returned first.

1. Iterate over all the n/w addrs (linked list) returned by getaddrinfo().
2. Move the n/w mask calculation part to mnt3_export_fill_hostspec()
   instead of doing it in mnt3_verify_auth() i.e. calculating for each
   mount request. It does not change for MOUNT req.
3. Integrate "subnet support code rpc-auth.addr..allow"
   and "NFS subdir auth code" to remove code duplication.

gNFS: RFE for NFS connection behavior

2013-11-15T00:07:02+00:00

Implement reconfigure() for NFS xlator so that volume set/reset wont
restart the NFS server process. But few options can not be reconfigured
dynamically e.g. nfs.mem-factor, nfs.port etc which needs NFS to be
restarted.

dual license: update remaining files with correct license text

Sayan Saha has previously approved changing everthing to dual license
but somehow we have missed changing these files.

I am explicitly not updating the copyright dates as nothing else that's
copyrightable has changed in these files with the license change
