build: add --without-server option

2018-02-21T18:08:14+00:00

With Gluster 4.0 we will not provide the server components for EL6 and
older. At one point Gluster 4.x will get GlusterD2, which requires
Golang tools in the distribution. EL6 does not contain these at the
moment.

With this change, it is possible to `./configure --without-server` which
prevents building glusterd and the xlators for the bricks. Building RPMs
can pass `--without server` and the glusterfs-server sub-package will
not be created.

build: out-of-tree builds generates files in the wrong directory

2016-09-18T16:34:37+00:00

And minor cleanup of a few of the Makefile.am files while we're
at it.

Rewrite the make rules to do what xdrgen does. Now we can get rid
of xdrgen.

Note 1. netbsd6's sed doesn't do -i. Why are we still running
smoke tests on netbsd6 and not netbsd7? We barely support netbsd7
as it is.

Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with
libglusterfs? A cut-and-paste mistake? It has no references to
symbols in libglusterfs.

Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_
regex that matches the same lines as the _extended_ regex
"/#(ifndef|define|endif)/". To match the extended regex sed needs to
be run with -r on Linux; with -E on *BSD. However NetBSD's and
FreeBSD's sed helpfully also provide -r for compatibility. Using a
basic regex avoids having to use a kludge in order to run sed with
the correct option on OS X.

Note 4. Not copying the bit of xdrgen that inserts copyright/license
boilerplate. AFAIK it's silly to pretend that machine generated
files like these can be copyrighted or need license boilerplate.
The XDR source files have their own copyright and license; and
their copyrights are bound to be more up to date than old
boilerplate inserted by a script. From what I've seen of other
Open Source projects -- e.g. gcc and its C parser files generated
by yacc and lex -- IIRC they don't bother to add copyright/license
boilerplate to their generated files.

It appears that it's a long-standing feature of make (SysV, BSD,
gnu) for out-of-tree builds to helpfully pretend that the source
files it can find in the VPATH "exist" as if they are in the $cwd.
rpcgen doesn't work well in this situation and generates files
with "bad" #include directives.

E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`,
you get an #include directive in the generated .c file like this:

  ...
  #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h"
  ...

which (obviously) results in compile errors on out-of-tree build
because the (generated) header file doesn't exist at that location.
Compared to `rpcgen ./glusterfs3-xdr.x` where you get:

  ...
  #include "glusterfs3-xdr.h"
  ...

Which is what we need. We have to resort to some Stupid Make Tricks
like the addition of various .PHONY targets to work around the VPATH
"help".

Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/...
looks exactly like -I$(top_srcdir)/rpc/xdr/...  Don't be fooled though.
And don't delete the -I$(top_builddir)/rpc/xdr/... bits

build: export minimum symbols from xlators for correct resolution

2015-09-24T14:37:42+00:00

We've been lucky that we haven't had any symbol collisions until now.
Now we have a collision between the snapview-client's svc_lookup() and
libntirpc's svc_lookup() with nfs-ganesha's FSAL_GLUSTER and libgfapi.

As a short term solution all the snapview-client's FOP methods were
changed to static scope. See http://review.gluster.org/11805. This
works in snapview-client because all the FOP methods are defined in
a single source file. This solution doesn't work for other xlators
with FOP methods defined in multiple source files.

To address this we link with libtool's '-export-symbols $symbol-file'
(a wrapper around `ld --version-script ...` --- on linux anyway) and
only export the minimum required symbols from the xlator sharedlib.

N.B. the libtool man page says that the symbol file should be named
foo.sym, thus the rename of *.exports to *.sym. While foo.exports
worked, we will follow the documentation.

nfs: add auth-cache for the MOUNT protocol

2015-03-15T13:40:22+00:00

Authentication cache for the new fine grained contol for the MOUNT
protocol. The extended authentication (see Change-Id Ic060aac) benefits
from caching the access/permission checks that are done when an
NFS-client mounts an export.

This auth-cache will be used by Change-Id I181e8c1.

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.

nfs: add structures and functions for parsing netgroups

2015-03-11T16:27:50+00:00

Netgroups are often used by enterprises to group a set of systems. The
NFS /etc/exports file support the @netgroup notation, and Gluster/NFS
will get extended to support this notation as well. For this, it is
needed that Gluster/NFS learns to parse the netgroup format.

A change to glusterfsd (Change-Id I24c40d5) will add test cases where
the parsing is used for regression testing.

gNFS: Subdir mount does not work on UDP proto

2014-10-07T07:51:29+00:00

After enabling nfs.mount-udp, mounting a subdir on a volume over
NFS fails. Because mountudpproc3_mnt_3_svc() invokes nfs3_rootfh()
which internally calls mnt3_mntpath_to_export() to resolve the
mount path. mnt3_mntpath_to_export() just works if the mount path
requested is volume itself. It is not able to resolve, if the path
is a subdir inside the volume.

MOUNT over TCP uses mnt3_find_export() to resolve subdir path but
UDP can't use this routine because mnt3_find_export() needs the
req data (of type rpcsvc_request_t) and it's available only for
TCP version of RPC.

FIX:
(1) Use syncop_lookup() framework to resolve the MOUNT PATH by
    breaking it into components and resolve component-by-component.
    i.e. glfs_resolve_at () API from libgfapi shared object.
(2) If MOUNT PATH is subdir, then make sure subdir export is not
    disabled.
(3) Add auth mechanism to respect nfs.rpc-auth-allow/reject and
    subdir auth i.e. nfs.export-dir
(4) Enhanced error handling for MOUNT over UDP

build: make GLUSTERD_WORKDIR rely on localstatedir

2014-08-07T08:17:29+00:00

- Break-way from '/var/lib/glusterd' hard-coded previously,
  instead rely on 'configure' value from 'localstatedir'
- Provide 's/lib/db' as default working directory for gluster
  management daemon for BSD and Darwin based installations
- loff_t is really off_t on Darwin
- fix-off the warnings generated by clang on FreeBSD/Darwin
- Now 'tests/*' use GLUSTERD_WORKDIR a common variable for all
  platforms.
- Define proper environment for running tests, define correct PATH
  and LD_LIBRARY_PATH when running tests, so that the desired version
  of glusterfs is used, regardless where it is installed.
