When I corrected the profiles/Makefile to automatically find files to
install, I converted one variable name but missed a later location where
that variable was used, which broke the 'make check' target, because
directories would be handed to the apparmor parser. This patch corrects
that and also makes the VERBOSE flag report each profile name as it's
being handed to the parser.

fix a nasty little bug that can surface in apparmor 2.8 when
Hats/children profiles are used.
the matchflags in the dfa backend are not getting properly reset, which
results in a previously processed profiles match flags being used. This is
not a problem for most permissions but can result in x conflict errors.
Note: this should not result in profiles with the wrong x transitions loaded
as it causes compilation to file with an x conflict.
This is a minimal patch targeted at the 2.8 release. As such I have just
updated the delete_ruleset routine to clear the flags as it is already
being properly called for every rule set.
Apparmor 2.9/3.0 will have a different approach where it is not possible
to reuse the flags.

whether or not the filesystem has a fine enough timestamp resolution.
Occasionally even on filesystems like ext3, the two files' creation
dates would differ when created less than a second apart, which would
typically cause the 'Cache is used when cache is newer' test to fail
because the cached file would have the same timestamp as the profile.
The fix creates 10 files 0.1 seconds apart and ensures that all ten
have distinct timestamps.

to the apparmor_api subtree not getting added in the Makefile. Rather
Rather than require every sub-directory that gets added to be
enumerated, it uses find to determine what directories and files to
install, to avoid future breakage. It is admittedly slower than the
original code because install(1) is being invoked for every file in
the apparmor.d tree, rather than acting on wildcard globs. That said,
I think it's an acceptable tradeoff.

This patch adds a test script/driver for the aa-decode utility. The only
change from the previous versions is to support overriding the location
of the aa-decode to test via the APPARMOR_DECODE environment variable
and documenting the utils/ tests in the top level README.
The aa-decode test can be run directly from the commandline in the utils
directory like so:
test/test-aa-decode.py -v

This patch fixes two issue with the simple test driver. The first is
that child exec that actually ran the parser was located inside the
eval statement. This meant that if the exec failed for some reason
(like the parser didn't exist), the child wouldn't actually die,
but would pop out of the eval and continue running through the loop
of test profiles (while the parent process does the same). This meant
that if the script ran on the full testsuite with a misconfiguration,
it would explode creating O(n^2) processes, where n is the number of
testcase files -- with over 25k testcases, that's a lot. The fis is to
lift the child exec outside the eval{}, then an exec() failure causes
the child process to die correctly.
The second fix is that several of the testcases were added with the
DESCRIPTION field added in lower case (i.e. #=Description blah blah).
This fix makes the regex that pulls out the description not be
case-sensitive.

This patch replaces the hardcoded path to the in-tree apparmor parser
in several of the script based test scripts with the APPARMOR_PARSER
environment variable, keeping the hardcoded location as the default.
It also adds support for overriding the location of the parser via the
same environment variable. The make infrastructure is updated to use
this, though uses a different variable (PARSER) to drive it.
Thus 'make check PARSER=/some/path/to/an/alternate/apparmor_parser'
will run all the parser tests on that binary. This is useful for
running the testsuite in an automated post-install environment.
(It should be noted that doing so will still build and run the unit
test binaries based on the source tree.)

Handling stdin was totally broken (= no output) with the current log
format because aa-decode expected name= to be the last entry in the
log line.
This patch for stdin handling
- fixes the pattern to match the current log format (name= is NOT the
last part in the log entry)
- uses bash replacement to avoid some sed calls (which also means the
script now needs an explicit "#!/bin/bash")
- prints decoded filenames in double instead of single quotes to be
consistent with filenames that were not encoded
- also prints lines that do not contain an encoded filename (instead of
grepping them away)
- replace tr calls by perl's uc() (also for non-stdin mode)
- also handle encoded profile names (introduced by Steve)
- don't fail if a file or profile name contains a '
In other words: you can pipe your audit.log through aa-decode, and the
only difference to the raw audit.log is that filenames are decoded.

- It failed to remove coredump files named "core"
- It failed to properly detect "core.<pid>" files
- And it would fail if the coredump_pattern had been modified to
a different location.
This lead one of the tests to report it was passing when it
wasn't because it was detecting the previous tests core file.
- Fix the test to set the coredump_pattern, to dump into the
tmpdir used for the test.
- Make it so it will only detect the core file for the pid of
the last test run.
- And extend the test to have a couple of extra test cases.
