This patch creates a new utility, with the code previously used in the
init script 'restart' action, that removes unknown profiles which are
not found in /etc/apparmor.d/. The functionality was removed from the
common init script code in the fix for CVE-2017-6507.
The new utility prints a message containing the name of each unknown
profile before the profiles are removed. It also supports a dry run mode
so that an administrator can check which profiles will be removed before
unloading any unknown profiles.
If you backport this utility with the fix for CVE-2017-6507 to an
apparmor 2.10 release and your backported aa-remove-unknown utility is
sourcing the upstream rc.apparmor.functions file, you'll want to include
the following bug fix to prevent the aa-remove-unknown utility from
removing child profiles that it shouldn't remove:

The latex based techdoc in the parser/ tree adds a number of build
dependencies for downstreams to create it; it also is the primary
element to make the builds unrepeatable. Creating the techdoc and other
documentation when generating a tarball for distribution avoids all
that.
* Makefile: build documentation as part of the tarball creation. Skip
the libraries/libapparmor directory as it needs to have configure run
before the manpages can be made.
* changehat/mod_apparmor/Makefile, changehat/mod_apparmor/Makefile,
utils/Makefile, profiles/Makefile: create separate docs target,
some of them dummies.
* parser/Makefile: pull the techdoc out of the default build target, add
an extra_docs target to create it.

Remove the Perl aa-exec implementation, move the aa-exec(8) man page to
binutils/, and point the regression test to the C based aa-exec in
binutils/.
Note that the new C aa-exec does not implement the --file option which
was present in the Perl aa-exec. It encouraged running programs as root,
since root privileges were required to load the specified profile.
All other features of the Perl aa-exec are present in the C aa-exec.

Since the Makefile cleanup, the _clean target is only used to delete
manpages etc. generated from *.pod files.
This patch renames the _clean target to pod_clean to make it obvious
what it does.

- drop the symlink magic of the common/ directory, and just include
files directly from there.
- update comments indicating required steps to take when including
common/Make.rules
- drop make clean steps that refer to no longer generated tarballs,
specfiles, and symlinks to the common directory/Make.rules.
- don't silence clean steps if VERBOSE is set

utils/Makefile contains a grep -v "undefined name _". Some manual
testing shows that pyflakes doesn't print any warning about "_", so
this grep is superfluous.
Removing the grep also means we don't need a tempfile for the pyflakes
output anymore, which simplifies the pyflakes call a lot.

This patch adds a 'check_pod_files' make target to the common make
rules, and then fixes the errors it highlighted as well as most of
the warnings. It will cause 'make check' in most of the directories to
fail if there are errors in a pod file (but not if there are warnings).
Common issues were:
- using an '=over/=back' pair for code-like snippets that did not
contain any =items therein; the =over keyword is intended for
indenting lists of =item entries, and generates a warning if
there isn't any.
- not escaping '<' or '>'
- blank lines that contained spaces or tabs
The second -warnings flag passed to podchecker is to add additional
warnings, un-escaped '<' and '>' being of them.
I did not fix all of the warnings in apparmor.d.pod, as I have not come
up with a good warning-free way to express the BNF of the language
similar in format to what is currently generated. The existing
libapparmor warnings (complaints about duplicate =item definition
names) are actually a result of passing the second -warnings flag.
The integration into libapparmor is suboptimal due to automake's
expectation that there will be a test driver program(s) for make check
targets; that's why I added the podchecker call to the manpage
generation point.

In the conversion from perl to python, it got overlooked to add the
python-apparmor modules to the set of things to search for translatable
strings in. This patch addresses the issue.

With the conversion of the python utils, aa-easyprof got added to the
list of tools to be installed (in /usr/sbin/), but is already installed
(in /usr/bin) by the python-tools-setup.py distutils script, leaving two
copies of the tool in place. This patch filters out aa-easyprof from the
list of tools for the makefile to install itself, leaving it to
(continue to) be installed by the distutils script.

* 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.

This patch adds a make install target for the generated apparmor.vim
file, installing by default into /usr/share/apparmor based on IRC
discussions; alternate suggestions welcome. (Installing directly
into the vim syntax tree is difficult as the system path by default
contains the vim version number.)
This patch replaces the apparmor.vim generating script with a python
version that eliminates the need for using the replace tool from the
mysql-server package. It makes use of the automatically generated
lists of capabilities and network protocols provided by the build
infrastructure. I did not capture all the notes and TODOs that
Christian had in the shell script; I can do so if desired.
It also hooks the generation of the apparmor.vim file into the utils/
build and clean stages.
capabilities
This patch adds a new make target, check_severity_db, to the
utils/Makefile. It greps the severity.db for the presence of each
capability, as computed by the newly abstracted out variable in
common/Make.rules, and issues a build time error if it finds any
missing.
It also silences the check targets, so that only the output from them
will be emitted.
The aa-exec command can be used to launch an application under a specified
confinement, which may be different for what regular profile attachment
would apply.

This also refactors the manpage generation slightly since we no longer
need special cases for the manpages, and drops aa-eventd from the default

This eliminates the need to manually add a lang to the Makefile when a
new translation is submitted (svn add will still be necessary).
