so I did a quick skim and I am mostly happy with it. What I would like is a test if dbus support is available and to bail out if it isn't. I know we haven't done this before, but it is something that has been missing and I find I am really wanting with these new features. I have kicked out a proposed patch that should provide what is needed for dbus, and we can expand it if needed later I'll try to get a little more time with the patch later, currently its at the tentative Acked-by stage. > --- > tests/regression/apparmor/Makefile | 15 +- > tests/regression/apparmor/dbus.conf | 27 +++ > tests/regression/apparmor/dbus.inc | 96 ++++++++ > tests/regression/apparmor/dbus_common.c | 267 ++++++++++++++++++++++ > tests/regression/apparmor/dbus_common.h | 28 +++ > tests/regression/apparmor/dbus_message.c | 364 > ++++++++++++++++++++++++++++++ > tests/regression/apparmor/dbus_message.sh | 125 ++++++++++ > tests/regression/apparmor/dbus_service.c | 316 ++++++++++++++++++++++++++ > tests/regression/apparmor/dbus_service.sh | 136 +++++++++++ > 9 files changed, 1373 insertions(+), 1 deletion(-) > create mode 100644 tests/regression/apparmor/dbus.conf > create mode 100644 tests/regression/apparmor/dbus.inc > create mode 100644 tests/regression/apparmor/dbus_common.c > create mode 100644 tests/regression/apparmor/dbus_common.h > create mode 100644 tests/regression/apparmor/dbus_message.c > create mode 100755 tests/regression/apparmor/dbus_message.sh > create mode 100644 tests/regression/apparmor/dbus_service.c > create mode 100755 tests/regression/apparmor/dbus_service.sh > > diff --git a/tests/regression/apparmor/Makefile > b/tests/regression/apparmor/Makefile > index 2021f51..0a05655 100644 > --- a/tests/regression/apparmor/Makefile > +++ b/tests/regression/apparmor/Makefile > @@ -23,6 +23,8 @@ SRC=access.c \ > chown.c \ > clone.c \ > coredump.c \ > + dbus_message.c \ > + dbus_service.c \ > deleted.c \ > environ.c \ > env_check.c \ > @@ -118,6 +120,8 @@ TESTS=access \ > chdir \ > clone \ > coredump \ > + dbus_message \ > + dbus_service \ > deleted \ > environ \ > exec \ > @@ -161,6 +165,15 @@ all: $(EXEC) changehat.h > changehat_pthread: changehat_pthread.c changehat.h > ${CC} ${CFLAGS} ${LDFLAGS} $< -o $@ ${LDLIBS} -pthread > > +dbus_common.o: dbus_common.c dbus_common.h > + ${CC} ${CFLAGS} ${LDFLAGS} $^ -c ${LDLIBS} $(shell pkg-config --cflags > --libs dbus-1) > + > +dbus_message: dbus_message.c dbus_common.o > + ${CC} ${CFLAGS} ${LDFLAGS} $^ -o dbus_message ${LDLIBS} $(shell > pkg-config --cflags --libs dbus-1) > + > +dbus_service: dbus_message dbus_service.c dbus_common.o > + ${CC} ${CFLAGS} ${LDFLAGS} $(filter-out dbus_message, $^) -o > dbus_service ${LDLIBS} $(shell pkg-config --cflags --libs dbus-1) > + > tests: all > @if [ `whoami` = "root" ] ;\ > then \ > @@ -200,6 +213,6 @@ alltests: all > fi > > clean: > - rm -f $(EXEC) > + rm -f $(EXEC) dbus_common.o > > regex.sh: open exec > diff --git a/tests/regression/apparmor/dbus.conf > b/tests/regression/apparmor/dbus.conf > new file mode 100644 > index 0000000..96b88fb > --- /dev/null > +++ b/tests/regression/apparmor/dbus.conf > @@ -0,0 +1,27 @@ > +<!-- This configuration file controls the per-user-login-session message bus. > + Add a session-local.conf and edit that rather than changing this > + file directly. --> > + > +<!DOCTYPE busconfig PUBLIC "-//freedesktop//DTD D-Bus Bus Configuration > 1.0//EN" > + "http://www.freedesktop.org/standards/dbus/1.0/busconfig.dtd"> > +<busconfig> > + <!-- Our well-known bus type, don't change this --> > + <type>session</type> > + > + <!-- If we fork, keep the user's original umask to avoid affecting > + the behavior of child processes. --> > + <keep_umask/> > + > + <listen>unix:tmpdir=/tmp</listen> > + > + <standard_session_servicedirs /> > + > + <policy context="default"> > + <!-- Allow everything to be sent --> > + <allow send_destination="*" eavesdrop="true"/> > + <!-- Allow everything to be received --> > + <allow eavesdrop="true"/> > + <!-- Allow anyone to own anything --> > + <allow own="*"/> > + </policy> > +</busconfig> > diff --git a/tests/regression/apparmor/dbus.inc > b/tests/regression/apparmor/dbus.inc > new file mode 100644 > index 0000000..ecf9488 > --- /dev/null > +++ b/tests/regression/apparmor/dbus.inc > @@ -0,0 +1,96 @@ > +# vim:syntax=sh > +# > +# Copyright (C) 2013 Canonical, Ltd. > +# > +# This program is free software; you can redistribute it and/or > +# modify it under the terms of the GNU General Public License as > +# published by the Free Software Foundation, version 2 of the > +# License. > + > +gendbusprofile() > +{ > + genprofile --stdin <<EOF > +$test { > + @{gen $test} > + $@ > +} > +EOF > +} > + > +start_bus() > +{ > + out=$(dbus-daemon --fork --print-pid --print-address > --config-file=dbus.conf) > + if [ $?
