Bug description:
Nvidia desktop users need the following AppArmor permissions to avoid denials:
owner /tmp/gl* mrw,
But this rule breaks application confinement such that apps are able
to tamper with each other. Interestingly, apps still run without the
rule, so we can explicitly deny it for now.
The use of /tmp is apparently hardcoded and does not honor TMPDIR
(application confinement will setup TMPDIR to a private area for the app).
strace confirms this:
24603 mkdir("/tmp", 0777) = -1 EEXIST (File exists)
24603 open("/tmp/glBRPYmm", O_RDWR|O_CREAT|O_EXCL, 0600) = -1 EACCES
(Permission denied)
While the use of O_EXCL is safe however, we don't allow access to /tmp
for confined apps and libraries/applications should always honor
TMPDIR.
