From: John Johansen <john.johansen@xxxxxxxxxxxxx> This patch has been added to the 3.12 stable tree. If you have any objections, please let us know. =============== commit 3d40658c977769ce2138f286cf131537bf68bdfe upstream. After a policy replacement, the task cred may be out of date and need to be updated. However change_hat is using the stale profiles from the out of date cred resulting in either: a stale profile being applied or, incorrect failure when searching for a hat profile as it has been migrated to the new parent profile. Fixes: 01e2b670aa898a39259bc85c78e3d74820f4d3b6 (failure to find hat) Fixes: 898127c34ec03291c86f4ff3856d79e9e18952bc (stale policy being applied) Bugzilla: https://bugzilla.suse.com/show_bug.cgi?id=1000287 Signed-off-by: John Johansen <john.johansen@xxxxxxxxxxxxx> Signed-off-by: James Morris <james.l.morris@xxxxxxxxxx> Signed-off-by: Jiri Slaby <jslaby@xxxxxxx> --- security/apparmor/domain.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/security/apparmor/domain.c b/security/apparmor/domain.c index 26c607c971f5..0c23888b9816 100644 --- a/security/apparmor/domain.c +++ b/security/apparmor/domain.c @@ -629,8 +629,8 @@ int aa_change_hat(const char *hats[], int count, u64 token, bool permtest) /* released below */ cred = get_current_cred(); cxt = cred_cxt(cred); - profile = aa_cred_profile(cred); - previous_profile = cxt->previous; + profile = aa_get_newest_profile(aa_cred_profile(cred)); + previous_profile = aa_get_newest_profile(cxt->previous); if (unconfined(profile)) { info = "unconfined"; @@ -726,6 +726,8 @@ audit: out: aa_put_profile(hat); kfree(name); + aa_put_profile(profile); + aa_put_profile(previous_profile); put_cred(cred); return error; -- 2.11.0 -- To unsubscribe from this list: send the line "unsubscribe stable" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
