... instead of keeping an own version of it witht the exact same code
and a TODO note to use the one from common.
Also adjust the aa-easyprof tests to directly import AppArmorException
from apparmor.common.
The test-aa-easyprof.py script was attempting to do its own special
setup to import the in-tree easyprof module. However, this proved to be
very flaky and resulted in the test periodically failing due to an
AttributeError the first time easyprof.parse_args() was called.
This patch removes the flakiness by trusting that PYTHONPATH is set up
appropriately before the test script is ran. PYTHONPATH is already
initialized appropriately by utils/test/Makefile according to the
USE_SYSTEM make variable.

if USE_SYSTEM is not set, the utils make check target will instruct
test-aa-easyprof.py to provide the path of the in-tree parser executable
to aa-easyprof.
If USE_SYSTEM is set, the default parser path (/sbin/apparmor_parser or
the result of `which apparmor_parser`) is used.
The test-aa-easyprof.py script receives the parser path by checking the
__AA_PARSER environment variable. This environment variable is strictly
used by the test script and not any user-facing code so two leading
underscores were used.

https://launchpad.net/bugs/1521031
aa-easyprof accepts a list of abstractions to include and, by default,
execs apparmor_parser to verify the generated profile including any
abstractions. However, aa-easyprof didn't provide the same flexibility
as apparmor_parser when it came to where in the filesystem the
abstraction files could exist.
The parser supports --base (defaulting to /etc/apparmor.d) and --Include
(defaulting to unset) options to specify the search paths for
abstraction files. This patch adds the same options to aa-easyprof to
aide in two different situations:
1) Some Ubuntu packages use aa-easyprof to generate AppArmor profiles
at build time. Something that has been previously needed is a way
for those packages to ship their own abstractions file(s) that are
#included in the easyprof-generated profile. That's not been
possible since the abstraction file(s) have not yet been installed
during the package build.
2) The test-aa-easyprof.py script contains some tests that specify
abstractions that should be #included. Without the ability to
specify a different --base or --Include directory, the abstractions
were required to be present in /etc/apparmor.d/abstractions/ or the
tests would fail. This prevents the Python utils from being able to
strictly test against in-tree code/profiles/etc.
I don't like the names of the command line options --base and --Include.
They're not particularly descriptive and the capital 'I' is not user
friendly. However, I decided to preserve the name of the options from
apparmor_parser.

As discussed a while ago, switch the utils (including their tests) to
use python3 by default. While on it, drop usage of "env" to always get
the system python3 instead of a random one that happens to live
somewhere in $PATH.
In practise, this patch doesn't change much - AFAIK openSUSE, Debian and
Ubuntu already patch aa-* to use python3.
Also add a note to README to officially deprecate Python 2.x.
(I won't break Python 2.x support intentionally - unless some future
change gives me a very good reason to finally drop Python 2.x support.)

This patch fixes the testsuite for aa-easyprof when the easyprof
utilities and configuration files are not installed in the system.
What was happening was that verify_manifest was calling parse_args()
without the synthetic arguments created by the test case and passing
the result to AppArmorEasyProfile(). Because parse_args() didn't
have the synthetic arguments, it would parse the actual command line
arguments passed to the testscript, which of course didn't specify the
alternate configuration file location. This would work when easyprof
had been installed in the system, because the fallback configuration
file in /etc/apparmor/easyprof.conf would exist and specify template
and policy group locations. Without that, though, the tests would abort
due to not knowing the location of the templates and policy groups.
This patch fixes the issue by passing the synthetic argument list
to verify_manifest, which uses that when calling parse_args(). A
debugging statement that states which conffile is being used when
AppArmorEasyProfile is being instantiated.

The relative directory tests in test-aa-easyprof.py were failing when
TMPDIR pointed to a directory that was a symlink, because the generated
tmpdir path was not the same as the realpath that easyprof resolved to.
This patch sets the tmpdir to the realpath of the result of the
tempfile.mkdtemp() to avoid the issue.

The test-aa-easyprof.py script has '/bin/ls' hardcoded as a path;
however, on systems that have undergone UsrMove, this is a symlink to
/usr/bin/ls. This patch fixes the issue by getting the realpath of
/bin/ls and storing it as an instance field.

* the application, library, documentation and installation script
* the initial templates and policy groups. This will undoubtedly need
refinement as we get feedback from users. Initial policy is based on Ubuntu's
Application Review Board (ARB) requirements[2].
* tests for the library
* Makefile integration
Templates are stored in /usr/share/apparmor/easyprof/templates and policy
groups in /usr/share/apparmor/easyprof/policygroups. This can be adjusted via
/etc/apparmor/easyprof.conf.
The aa-easyprof.pod has complete documentation on usage with some
additional information in utils/easyprof/README (mostly duplicated
here).
Testing can be performed in a number of ways:
$ cd utils ; make check # runs unit tests and pyflakes
Unit tests manually:
$ ./test/test-aa-easyprof.py
In source manual testing:
$ ./aa-easyprof --templates-dir=./easyprof/templates \
--policy-groups-dir=./easyprof/policygroups \
... \
/opt/foo/bin/foo
Post-install manual testing:
$ make DESTDIR=/tmp/test PERLDIR=/tmp/test/usr/share/perl5/Immunix install
$ cd /tmp/test
$ PYTHONPATH=/tmp/test/usr/local/.../dist-packages ./usr/bin/aa-easyprof \
--templates-dir=/tmp/test/usr/share/apparmor/easyprof/templates \
--policy-groups-dir=/tmp/test/usr/share/apparmor/easyprof/policygroups \
/opt/bin/foo
(you may also adjust /tmp/test/etc/apparmor/easyprof.conf to avoid
specifying --templates-dir and --policy-groups-dir).
Committing this now based on conversation with John and Steve.
