f26eb42862 Add paxcheck make lint target
This uses scanelf (from pax-utils) to check for any issues with the
binaries. It currently checks for executable stacks and textrels.
The checks are in a script so can be extended easily in the future for
more checks.

Executable stacks and textrels are frequently caused by issues in asm
files and lead to security and perf problems.

6bb24f4dc7 Add the ZFS Test Suite
Add the ZFS Test Suite and test-runner framework from illumos.
This is a continuation of the work done by Turbo Fredriksson to
port the ZFS Test Suite to Linux.  While this work was originally
conceived as a stand alone project integrating it directly with
the ZoL source tree has several advantages:

  * Allows the ZFS Test Suite to be packaged in zfs-test package.
    * Facilitates easy integration with the CI testing.
    * Users can locally run the ZFS Test Suite to validate ZFS.
      This testing should ONLY be done on a dedicated test system
      because the ZFS Test Suite in its current form is destructive.
  * Allows the ZFS Test Suite to be run directly in the ZoL source
    tree enabled developers to iterate quickly during development.
  * Developers can easily add/modify tests in the framework as
    features are added or functionality is changed.  The tests
    will then always be in sync with the implementation.

Full documentation for how to run the ZFS Test Suite is available
in the tests/README.md file.

Warning: This test suite is designed to be run on a dedicated test
system.  It will make modifications to the system including, but
not limited to, the following.

  * Adding new users
  * Adding new groups
  * Modifying the following /proc files:
    * /proc/sys/kernel/core_pattern
    * /proc/sys/kernel/core_uses_pid
  * Creating directories under /

Notes:
  * Not all of the test cases are expected to pass and by default
    these test cases are disabled.  The failures are primarily due
    to assumption made for illumos which are invalid under Linux.
  * When updating these test cases it should be done in as generic
    a way as possible so the patch can be submitted back upstream.
    Most existing library functions have been updated to be Linux
    aware, and the following functions and variables have been added.
    * Functions:
      * is_linux          - Used to wrap a Linux specific section.
      * block_device_wait - Waits for block devices to be added to /dev/.
    * Variables:            Linux          Illumos
      * ZVOL_DEVDIR         "/dev/zvol"    "/dev/zvol/dsk"
      * ZVOL_RDEVDIR        "/dev/zvol"    "/dev/zvol/rdsk"
      * DEV_DSKDIR          "/dev"         "/dev/dsk"
      * DEV_RDSKDIR         "/dev"         "/dev/rdsk"
      * NEWFS_DEFAULT_FS    "ext2"         "ufs"
  * Many of the disabled test cases fail because 'zfs/zpool destroy'
    returns EBUSY.  This is largely causes by the asynchronous nature
    of device handling on Linux and is expected, the impacted test
    cases will need to be updated to handle this.
  * There are several test cases which have been disabled because
    they can trigger a deadlock.  A primary example of this is to
    recursively create zpools within zpools.  These tests have been
    disabled until the root issue can be addressed.
  * Illumos specific utilities such as (mkfile) should be added to
    the tests/zfs-tests/cmd/ directory.  Custom programs required by
    the test scripts can also be added here.
  * SELinux should be either is permissive mode or disabled when
    running the tests.  The test cases should be updated to conform
    to a standard policy.
  * Redundant test functionality has been removed (zfault.sh).
  * Existing test scripts (zconfig.sh) should be migrated to use
    the framework for consistency and ease of testing.
  * The DISKS environment variable currently only supports loopback
    devices because of how the ZFS Test Suite expects partitions to
    be named (p1, p2, etc).  Support must be added to generate the
    correct partition name based on the device location and name.
  * The ZFS Test Suite is part of the illumos code base at:
    https://github.com/illumos/illumos-gate/tree/master/usr/src/test

47a4a6fd5f Support parallel build trees (VPATH builds)
Build products from an out of tree build should be written
relative to the build directory.  Sources should be referred
to by their locations in the source directory.

This is accomplished by adding the 'src' and 'obj' variables
for the module Makefile.am, using relative paths to reference
source files, and by setting VPATH when source files are not
co-located with the Makefile.  This enables the following:

  $ mkdir build
  $ cd build
  $ ../configure \
    --with-spl=$HOME/src/git/spl/ \
    --with-spl-obj=$HOME/src/git/spl/build
  $ make -s

This change also has the advantage of resolving the following
warning which is generated by modern versions of automake.

  Makefile.am:00: warning: source file 'xxx' is in a subdirectory,
  Makefile.am:00: but option 'subdir-objects' is disabled

a35beedfb3 Add cstyle.pl utility and cstyle.1 man page
Cstyle is the C source style checker used by Illumos.  Since the
original ZFS source was written using these style guidelines they
must also be followed by ZoL for consistency.

The checker has been added to the scripts directory and may be
run on a per file basis.  New patches should be careful to avoid
introducing new style warnings.

Additionally, the 'checkstyle' target has been added to the top
level Makefile and can be used to check the entire source tree.
While Zol has historically attempted to follow the SunOS style
guide the lack of a rigorous style checker has allowed various
warning to be introduced.  Currently there are 2211 reported
style violations and we want to gradually eliminate these from
the tree.

Note the cstyle.1 man page is provided under man/man1/cstyle.1
but since it is a developer utility it is not installed along
with the other man pages.

f6fb7651a0 Use 'git describe' for working builds
When building from an arbitrary commit in the git tree it's useful
for the resulting packages to be uniquely identifiable.  Therefore,
the build system has been updated to detect if your compiling in
git tree.

If you are building in a git tree, and there are commits after the
last annotated tag.  Then the <id>-<hash> component of 'git describe'
will be used to overwrite the 'Release:' field in the META file.

The only tricky part is that to ensure the 'make dist' tarball is
built using the correct release.  A dist-hook was added to the top
level make file to rewrite the META file using the correct release.

f3757573a6 Refresh RPM packaging
Refresh the existing RPM packaging to conform to the 'Fedora
Packaging Guidelines'.  This includes adopting the kmods2
packaging standard which is used fod kmods distributed by
rpmfusion for Fedora/RHEL.

  http://fedoraproject.org/wiki/Packaging:Guidelines
  http://rpmfusion.org/Packaging/KernelModules/Kmods2

While the spec files have been entirely rewritten from a
user perspective the only major changes are:

* The Fedora packages now have a build dependency on the
  rpmfusion repositories.  The generic kmod packages also
  have a new dependency on kmodtool-1.22 but it is bundled
  with the source rpm so no additional packages are needed.

* The kernel binary module packages have been renamed from
  zfs-modules-* to kmod-zfs-* as specificed by kmods2.

* The is now a common kmod-zfs-devel-* package in addition
  to the per-kernel devel packages.  The common package
  contains the development headers while the per-kernel
  package contains kernel specific build products.

26e08952e6 Support building a zfs-modules-dkms sub package
This commit adds support for building a zfs-modules-dkms sub package
built around Dynamic Kernel Module Support. This is to allow building
packages using the DKMS infrastructure which is intended to ease the
burden of kernel version changes, upgrades, etc.

By default zfs-modules-dkms-* sub package will be built as part of
the 'make rpm' target.  Alternately, you can build only the DKMS
module package using the 'make rpm-dkms' target.

Examples:

    # To build packaged binaries as well as a dkms packages
    $ ./configure && make rpm

    # To build only the packaged binary utilities and dkms packages
    $ ./configure && make rpm-utils rpm-dkms

Note: Only the RHEL 5/6, CHAOS 5, and Fedora distributions are
      supported for building the dkms sub package.

This is slightly problematic when the file is needed without running

6ba3b44614 Add make rule for building Arch Linux packages
Added the necessary build infrastructure for building packages
compatible with the Arch Linux distribution. As such, one can now run:

    $ ./configure
    $ make pkg     # Alternatively, one can run 'make arch' as well

on the Arch Linux machine to create two binary packages compatible with
the pacman package manager, one for the zfs userland utilities and
another for the zfs kernel modules. The new packages can then be
installed by running:

    # pacman -U $package.pkg.tar.xz

In addition, source-only packages suitable for an Arch Linux chroot
environment or remote builder can also be build using the 'sarch' make
rule.

NOTE: Since the source dist tarball is created on the fly from the head
of the build tree, it's MD5 hash signature will be continually influx.
As a result, the md5sum variable was intentionally omitted from the
PKGBUILD files, and the '--skipinteg' makepkg option is used. This may
or may not have any serious security implications, as the source tarball
is not being downloaded from an outside source.

12d06bac9b Move udev rules from /etc/udev to /lib/udev
This change moves the default install location for the zfs udev
rules from /etc/udev/ to /lib/udev/.  The correct convention is
for rules provided by a package to be installed in /lib/udev/.
The /etc/udev/ directory is reserved for custom rules or local
overrides.

Additionally, this patch cleans up some abuse of the bindir install
location by adding a udevdir and udevruledir install directories.
This allows us to revert to the default bin install location.  The
udev install directories can be set with the following new options.

ae26d0465a Add dracut support
To simplify the process of using zfs as your root filesystem a
zfs-drucat sub-package has been added.  This sub-package adds a zfs
dracut module which allows your initramfs to be rebuilt with zfs
support.  The process for doing this is still complicated but there
is clearly interest from the community about getting this working
well and documented.  This should help lay some of the groundwork.

Longer term these changes should be pushed in the upstream dracut
package.  Once that occurs this subpackage will no longer be
required for new systems, however we may want to conditionally
build this package in the future for systems running older
dracut versions.

6283f55ea1 Support custom build directories and move includes
One of the neat tricks an autoconf style project is capable of
is allow configurion/building in a directory other than the
source directory.  The major advantage to this is that you can
build the project various different ways while making changes
in a single source tree.

For example, this project is designed to work on various different
Linux distributions each of which work slightly differently.  This
means that changes need to verified on each of those supported
distributions perferably before the change is committed to the
public git repo.

Using nfs and custom build directories makes this much easier.
I now have a single source tree in nfs mounted on several different
systems each running a supported distribution.  When I make a
change to the source base I suspect may break things I can
concurrently build from the same source on all the systems each
in their own subdirectory.

wget -c http://github.com/downloads/behlendorf/zfs/zfs-x.y.z.tar.gz
tar -xzf zfs-x.y.z.tar.gz
cd zfs-x-y-z

------------------------- run concurrently ----------------------
<ubuntu system>  <fedora system>  <debian system>  <rhel6 system>
mkdir ubuntu     mkdir fedora     mkdir debian     mkdir rhel6
cd ubuntu        cd fedora        cd debian        cd rhel6
../configure     ../configure     ../configure     ../configure
make             make             make             make
make check       make check       make check       make check

This change also moves many of the include headers from individual
incude/sys directories under the modules directory in to a single
top level include directory.  This has the advantage of making
the build rules cleaner and logically it makes a bit more sense.

Fix type in lib/libzpool/Makefile.am which was preventing

I simply had the name wrong in the Makefile.am.

Regenerated autogen.sh build products.
