Bug Description

from source, I'm running the tests and the makefile fails at the end with:

running stackprofile
Makefile:303: recipe for target 'tests' failed
make: *** [tests] Error 1

No idea why that is happening. It's breaking on our kernel team regression tests runs, so can this be investigated? The source was fetched using "apt-get source apparmor".

A full run is below:

Hi Colin,

stackprofile is just the last test in the for-loop, it's the make tests target failing as a whole. It looks like for some reason the environ test is failing.

What kernel are you running this on?

Thanks.

Okay, thanks to jj for providing kernels, I've now reproduced this in zesty with his patch set applied.

It's failing in the 'confined/complain' tests. There's a bug in the environ.c test that prevents the test harness from detecting/reporting the failure correctly. When that's fixed, the output looks like:

Examining the individual test, the environ program is attempting to run the env_check program while confined by a complain mode profile, but is not permitted to do so. From strace output:

[pid 5706] execve("/home/ubuntu/tmp/apparmor-2.10.95/tests/regression/apparmor/env_check", ["/home/ubuntu/tmp/apparmor-2.10.9"..., "FOO=BAR"], [/* 24 vars */]) = -1 EACCES (Permission denied)

The apparmor audit message is correctly claiming that its allowing it (but isn't permitted by the loaded policy):

[ 1726.404464] audit: type=1400 audit(1485991672.366:348): apparmor="ALLOWED" operation="exec" profile="/home/ubuntu/tmp/apparmor-2.10.95/tests/regression/apparmor/environ" name="/home/ubuntu/tmp/apparmor-2.10.95/tests/regression/apparmor/env_check" pid=5700 comm="environ" requested_mask="x" denied_mask="x" fsuid=1000 ouid=1000 target="/home/ubuntu/tmp/apparmor-2.10.95/tests/regression/apparmor/environ//null-/home/ubuntu/tmp/apparmor-2.10.95/tests/regression/apparmor/env_check"

but that doesn't seem to be the case. So I think there's something wonky in John's patch set.

John, can you take a look at what's going on?

The zesty 4.9.0 kernel (once I hacked around a problem I was having the
kernel modules not generating a working initrd) is solving the issue for
me, too.

Thanks John!
