... and self.pid which is also unused.
This simple change also means to adjust all the code that uses ReadLog.
We get rid of log_pid in aa.py, and have to change lots of test-*
This parameter is always [], so we can simplify the ReadLog __init__()
parameters.
Note that some tests handed over '' instead of []. This was a bug, but
didn't matter because those tests only use a small portion of ReadLog.

Storing these event details depending on the operation type only makes
things more difficult because it's hard to differenciate between file
and network events.
Note that this happens at the first log parsing stage (libapparmor log
event -> temporary python array) and therefore doesn't add a serious
memory footprint. The event tree will still only contain the elements
relevant for the actual event type.
This change means that lots of testcases now get 3 more fields (all
None) when testing parse_event(), so update all affected testcases.
(test-network doesn't need a change for probably obvious reasons.)
Also rename a misnamed test in test-change_profile.
Acked-by: Seth Arnold <seth.arnold@canonical.com> for trunk and 2.10.
Add a testcase with exec-only permissions (which get ignored by
get_perms_for_path()) to increase FileRule test coverage to 100%.

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.)

(since 2016-08-23, but the commit had to wait for the FileRule series
because it touches test-file.py)
Adding a rule to *Ruleset means it simply gets added. This also means
that then-superfluous rules will be kept.
This patch adds an optional cleanup flag to add(). If set, rules covered
by the new rule will be deleted. The difference to delete_duplicates()
is that cleanup only deletes rules that are covered by the new rule, but
keeps other, unrelated superfluous rules.
Also return the number of deleted rules to give the UI a chance to
report this number.
Finally, adjust the existing tests for FileRuleset to ensure default
mode (without cleanup) doesn't delete any rules, and add a test using
the cleanup flag.

get_exec_rules_for_path() returns a FileRuleset with all rules matching
the given path.
get_exec_conflict_rules() returns a FileRuleset with all exec rules that
conflict with the given oldrule. This will be used by aa-mergeprof to
ask the user which rule he wants to keep.
Also add tests for both functions.

Merge the existing and requested permissions into a nice set of headers
that can be displayed by aa-logprof. This will look like:
Path: /foo
Old Mode: r + owner w
New Mode: rw
Also split off a _join_given_perms() function off _joint_perms() so that
we can use the permission string merging for things not stored in self.*.
Finally add some tests for logprof_header().

- get_rules_for_path() returns all rules matching the given path
(both exact matches and AARE matches)
- get_perms_for_path() returns the merged permissions for the given
path and a list of paths used in the matching rules
Also add tests for these two functions.

Also add a rank_path() function to severity.py and change rank() to call
rank_path() for paths.
Long-term goal: get rid of the type "guessing" in rank()
Finally add some tests, mostly based on test-severity.py SeverityTest

This means adding
- self.can_edit - True if editing via '(N)ew' should be possible (will
be False for bare file rules)
- edit_header() - returns the prompt text and the current path
- validate_edit() - checks if the new path matches the original one
- store_edit() - changes the path to the new one (even if it doesn't
match the old one)
self.can_edit and the 3 functions are also added to BaseRule:
- can_edit is False by default
- the functions raise a NotImplementedError
Also add tests for the added code.

Add the glob() and glob_ext() functions to FileRule, and set
self.can_glob and self.can_glob_ext. Also add some tests (just enough to
make sure the FileRule integration works - the globbing is handled
inside AARE,and the AARE tests contain more testcases).
Note that the implementation differs from the original plan (which was
to have globbing in *Ruleset). Therefore add can_glob and can_glob_ext
to BaseRule (both default to False), and add a comment to BaseRuleset
that globbing needs to be removed from all *Ruleset classes.

As discussed, I added a pointer to the test-aare.py globbing tests in
test-file.py.
aa-logprof needs to check if an exec rule for a given path exists.
This patch adds a __FileAnyExec class to FileRule, as well as ANY_EXEC
(which should be used externally, similar to ALL), and adjusts several
checks to allow it as a special execute mode.
This will allow to use is_covered() (or aa.py is_known_rule()) to find
out if execute is permitted, which replaces aa.py profile_known_exec()
in one of the following patches.
As usual, also add some tests.
Acked-by: Steve Beattie <steve@nxnw.org>
Note: as discussed, I adjusted the comment for 'pass' around line 240.
The parser accepts duplicated execute permissions as long as they don't
conflict. For example,
/bin/foo pxpxpxpx,
is a valid rule.
This patch changes FileRule to also accept those duplicated permissions,
even if it's unlikely to hit them outside of the parser tests ;-)
Also add some tests to make sure the parsing works as expected.
