+Subject: [PATCH 4/4] Smack: Assign smack_known_web label for kernel thread's
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Assign smack_known_web label for kernel thread's socket in the sk_alloc_security hook
+
+Creating struct sock by sk_alloc function in various kernel subsystems
+like bluetooth dosen't call smack_socket_post_create(). In such case,
+received sock label is the floor('_') label and makes access deny.
+
+Refers-to: https://review.tizen.org/gerrit/#/c/80717/4
