utils/apparmor/common.py: adjust for python3 (ie, make bi-lingual)
utils/apparmor/sandbox.py:
- set reasonable default template
- gen_policy_name() uses full pathname
- adjust for python3
http://thread.gmane.org/gmane.linux.kernel/1289986
This allows for drivers that support poll to prevent suspend. Adjust
utils/severity.db for this.

This patch moves the generation of file rules from apparmor.vim.in to
create-apparmor.vim.py. It also adds support for
- filenames in quotes
- reverse syntax (permissions first)
The patch also removes an outdated $Id header in apparmor.vim.in and
updates the copyright year.

* 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.

When writing out a profile, aa-logprof incorrectly converts PUx execute
permission modes to the syntactically invalid UPx mode, because the
function that converts the internal representation of permissions to
a string emits the U(nconfined) mode bit before the P bit.
This patch corrects this by reordering the way the exec permissions
are emitted, so that P and C modes come before U and i. Based on
http://wiki.apparmor.net/index.php/AppArmor_Core_Policy_Reference#Execute_rules
this should emit the modes correctly in all combined exec modes.
Other approaches to fixing this would require adjusting the data
structure that contains the permission modes, resulting in a more
invasive patch.

manpages (and adjust it so that it's one rule instead of eight). It
also fixes the above problem and a similar problem in the aa-exec
manpage.

This patch calls autodep on the 'exec'ed binary when the user selects
to place that execution in a child profile. Previously, logprof would
create an entirely empty child profile in complain mode (this fix
still leaves the child profile in complain mode).
This patch fixes a couple of issue with autodep:
1) The initial profile construction had not been adjusted to include
the 'allow' or 'deny' hash prefixing the path elements. This
fixes it by eliminating the path portion entirely and pushing
the path based accesses to the later analysis section of code.
2) the mode of the original binary was accidentally getting reset
to 0, when it was intended to initialize the audit field to 0.
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.
This patch adds several missing capabilities to the utils/
severity.db file as detected by the newly added make check target,
along with corresponding severity levels that I believe :re appropriate
(discussion welcome):
CAP_MAC_ADMIN 10
CAP_MAC_OVERRIDE 10
CAP_SETFCAP 9
CAP_SYSLOG 8
CAP_WAKE_ALARM 8
The latter two are undocumented in the capabilities(7) man page
provided in Ubuntu 12.04; the syslog one is the separation out of
accessing the dmesg buffer from CAP_SYSADMIN, and the CAP_WAKE_ALARM
allows setting alarms that would wake a system from a suspended state,
if my reading is correct.
This also fixes a trailing whitespace on CAP_CHOWN, moves
CAP_DAC_READ_SEARCH to the end of the section of capabilities it's
in due to its lower priority level (7).
