Replace RE_PROFILE_START with RE_PROFILE_START_2 and adjust all
code sections that used RE_PROFILE_START_2.
The only real change is that test_get_flags_invalid_01 and
test_get_flags_invalid_02 now expect AppArmorException instead of
AppArmorBug.

This patch implements attachment handling - aa-logprof now works with
profiles that have an attachment defined, instead of ignoring audit.log
entries for those profiles.
Changes:
- parse_profile_start_line(): remove workaround that merged the
attachment into the profile name
- parse_profile_data(): store attachment when parsing a profile
- update test_parse_profile_start_03, test_serialize_parse_profile_start_03,
test_set_flags_nochange_09 and some parse_profile_start_line() tests -
they now expect correct attachment handling

this patch makes set_profile_flags more strict:
- raise AppArmorBug if newflags contains only whitespace
- raise AppArmorBug if the file doesn't contain the specified profile or
no profile at all
The tests are adjusted to expect AppArmorBug instead of a silent
failure. Also, some tests are added for profile=None, which means to
change the flags for all profiles in a file.
- test_set_flags_08 is now test_set_flags_invalid_04
- test_set_flags_invalid_03 is changed to only contain one reason for a
failure, not two ;-)

Changes in set_profile_flags():
- rewrite set_profile_flags to use parse_profile_start_line() and
write_header().
- replace the silent failure for non-existing files with a proper
exception (using lazy programming - the check is done by removing the
"if os.path.isfile()" check, open_file_read then raises the
exception ;-)
- comment out regex_hat_flag and the code that was supposed to handle
hat flags, which were totally broken. We'll need another patch to fix
it, and we also need to decide if we want to do that because it
introduces a behaviour change (currently, aa-complain etc. don't
change hat flags).
The tests for set_profile_flags() are also updated:
- prepend a space to comments because write_header always adds a space
between '{' and the comment
- remove a test with superfluous quotes that are no longer kept (that's
just a profile cleanup, so dropping that test is the easiest way)
- update test_set_flags_10 and test_set_flags_12 to use the correct
profile name
- enable the tests for invalid (empty) flags
- update the test for a non-existing file
Note: test_set_flags_10, test_set_flags_12 and test_set_flags_nochange_09
will fail with this patch applied. The next patch will fix that.

Change the write_header tests so that the 'profile_keyword' and
'header_comment' parameters can be (and are) tested:
- add a None for both to the existing tests
- add some tests that come with the profile keyword and/or a comment
Acked-by: Steve Beattie <steve@nxnw.org>
- add support for prof_data['header_comment'] (comment after '{')
and prof_data['profile_keyword'] (to force the 'profile' keyword, even
if it isn't needed) to write_header().
(set_profile_flags() will be the only user of these two for now)
- fix a crash if depth is not an integer - for example,
len(' ')/2 # 3 spaces = 1.5
would cause a crash.
Also add a test for 1.5 and 1.3 spaces.
- rewrite the handling of flags to avoid we have to maintain two
different template lines.
- update the tests to set 'profile_keyword' and 'header_comment' to None.
This avoids big changes in the test code. I'll send another patch that
makes sure profile_keyword and header_comment are tested ;-)

Add the attachment to the parse_profile_start() and
serialize_parse_profile_start() return values, and adjust the functions
calling the *parse_profile_start() functions to save the attachment in
the "attachment" variable (which isn't used yet).
Also adjust the tests for the added return value.
(Sorry for not getting the resultset right from the beginning!)

Also fix a little bug that added the profile keyword if the path needed
quotes (profile "/foo bar" - but "/foo bar" is enough). This was caused
by a regex that always matched on quoted paths (hint: "/ matches
^[^/] ;-)
Also add some tests with attachments and update the test for the bugfix
mentioned above.
Now the remaining part is to make sure that prof_data['attachment'] gets
set when parsing the profiles :-)

Also add loop support to test-aa.py.
BTW: In case you wonder - the need to replace unittest.TestCase with
AATest is intentional. It might look annoying, but it makes sure that
a test-*.py file doesn't contain a test class where tests = [...] is
ignored because it's still unittest.TestCase.
(Technically, setup_all_tests() will error out if a test class doesn't
contain tests = [...] - either explicit or via its parent AATest.)

Add various tests for set_profile_flags, and document various
interesting[tm] things I discovered while writing the tests (see
the inline comments for details).
Also adds a read_file() function to common_test.py.
The most interesting[tm] thing I found is:
regex_hat_flag = re.compile('^([a-z]*)\s+([A-Z]*)\s*(#.*)?$')
which matches various unexpected things - but not a hat :-/
(see mailinglist for all funny details)

Convert serialize_parse_profile_start() to use
parse_profile_start_line(), and adjust a test to expect an AppArmorBug
instead of an AttributeError exception.
Also add two tests (they succeed with the old and the new code).
Note that these tests document interesting[tm] behaviour - I tend to
think that those cases should raise an exception, but I'm not sure about
this because serialize_profile_from_old_profile() is a good example for
interesting[tm] code :-/
I couldn't come up with a real-world test profile that would hit those
cases without erroring out aa-logprof earlier - maybe the (more
sane-looking) parse_profiles() / serialize_parse_profile_start()
protects us from hitting this interesting[tm] behaviour.

The previous patch slightly changed the behaviour of parse_profile_start()
and get_profile_flags() - they raise AppArmorBug instead of
AppArmorException when specifying a line that is not the start of a
profile and therefore doesn't match RE_PROFILE_START_2.
This patch updates test-aa.py to expect the correct exceptions, and adds
another test with quoted profile name to ensure that stripping the
quotes works as expected.

Move the code for parsing the profile start ("/foo {") from aa.py
parse_profile_data() to a separate function parse_profile_start().
Most of the changes are just moving around code, with some small
exceptions:
- instead of handing over profile_data to parse_profile_start() to
modify it, it sets two variables (pps_set_profile and
pps_set_hat_external) as part of its return value, which are then
used in parse_profile_data() to set the flags in profile_data.
- existing_profiles[profile] = file is executed later, which means
it used the strip_quotes() version of profile now
- whitespace / tab level changes
The patch also adds some tests for the parse_profile_start() function.

Also adds a check to get_profile_flags() to catch an invalid syntax:
/foo ( ) {
was accepted by get_profile_flags, while
/foo () {
failed.
When testing with the parser, both result in a syntax error, therefore
the patch makes sure it also fails in get_profile_flags().

libapparmor _aa_is_blacklisted() - some extensions were missing in the
python code.
Also make the code more readable and add some testcases.
Notes:
- the original code additionally ignored *.swp. I didn't include that -
*.swp looks like vim swap files which are also dot files
- the python code ignores README files, but the C code doesn't
(do we need to add README in the C code?)

Also change check_for_apparmor() to allow easier testing by optionally
specifying alternative locations for /proc/filesystems and /proc/mounts
as parameter.
Note that the code in check_for_apparmor() differs from what the comment
says - valid_path() only does syntax checks, but doesn't check if the
directory exists. I added a comment saying exactly that.
