Use GLIBC xattr for attr tools and acl tools and library

[William Harrington]

Chris mentioned to use xattr.h from Glibc to build ACL. We don't need the ATTR package in the book.

Reference: ​http://lists.gnu.org/archive/html/acl-devel/2014-05/msg00001.html

I've edited some files and have attached a patch to apply to ACL.

Allows acl to use xattr from libc

[William Harrington]

Actually, we probably can't remove the ATTR package as we need the attr, getfattr, and setfattr programs and man-pages.

[William Harrington]

For ATTR, we can build the tools attr, getfattr, setfattr and install the man pages for them and skip installing the headers and libraries.

The tests will work fine. All 114 passed for me.

I've attached a patch for ATTR. This will make intallation of ATTR in all books much shorter and simpler. No need to install libraries. Just have one install of ATTR in each book.

With my server build the following tools link to libattr and means that they may need edits to use <sys/xattr.h> and not attempt to link to libattr with -lattr.

libcap will need an edit:

sed -i 's/-lattr//' libcap/Makefile

[William Harrington]

Shadow needs to be hacked for this. I don't think it is worth all of the effort to edit a bunch of source to use <sys/xattr.h> and change all the configure scripts which are looking for libattr.

[Martin Ward]

Yes have to agree with your last comment, checked gentoo, arch, fedora, all use stand alone attr lib
