From 3bbb7b2e9bbcd22e539e23034da753898fe3b4dc Mon Sep 17 00:00:00 2001 From: John Johansen Date: Sat, 26 Mar 2022 01:52:06 -0700 Subject: [PATCH] apparmor: fix setting unconfined mode on a loaded profile When loading a profile that is set to unconfined mode, that label flag is not set when it should be. Ensure it is set so that when used in a label the unconfined check will be applied correctly. Fixes: 038165070aa5 ("apparmor: allow setting any profile into the unconfined state") Signed-off-by: John Johansen --- security/apparmor/policy_unpack.c | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) diff --git a/security/apparmor/policy_unpack.c b/security/apparmor/policy_unpack.c index df4033db0e0f..302fecf9b197 100644 --- a/security/apparmor/policy_unpack.c +++ b/security/apparmor/policy_unpack.c @@ -750,16 +750,18 @@ static struct aa_profile *unpack_profile(struct aa_ext *e, char **ns_name) profile->label.flags |= FLAG_HAT; if (!unpack_u32(e, &tmp, NULL)) goto fail; - if (tmp == PACKED_MODE_COMPLAIN || (e->version & FORCE_COMPLAIN_FLAG)) + if (tmp == PACKED_MODE_COMPLAIN || (e->version & FORCE_COMPLAIN_FLAG)) { profile->mode = APPARMOR_COMPLAIN; - else if (tmp == PACKED_MODE_ENFORCE) + } else if (tmp == PACKED_MODE_ENFORCE) { profile->mode = APPARMOR_ENFORCE; - else if (tmp == PACKED_MODE_KILL) + } else if (tmp == PACKED_MODE_KILL) { profile->mode = APPARMOR_KILL; - else if (tmp == PACKED_MODE_UNCONFINED) + } else if (tmp == PACKED_MODE_UNCONFINED) { profile->mode = APPARMOR_UNCONFINED; - else + profile->label.flags |= FLAG_UNCONFINED; + } else { goto fail; + } if (!unpack_u32(e, &tmp, NULL)) goto fail; if (tmp)
