kernel/linux.git/security/apparmor/nulldfa.in, branch v4.14.60 Linux kernel stable tree (mirror) https://git.radix-linux.su/kernel/linux.git/atom?h=v4.14.60 2017-01-16T09:18:34+00:00 apparmor: add a default null dfa 2017-01-16T09:18:34+00:00 John Johansen john.johansen@canonical.com 2017-01-16T08:42:42+00:00 urn:sha1:11c236b89d7c26d58c55d5613a858600a4d2ab3a Instead of testing whether a given dfa exists in every code path, have a default null dfa that is used when loaded policy doesn't provide a dfa. This will let us get rid of special casing and avoid dereference bugs when special casing is missed. Signed-off-by: John Johansen <john.johansen@canonical.com>
