-stable review patch. If anyone has any objections, please let us know. --------------------- From: Patrick McHardy Upstream commit: 3480c63bdf008e9289aab94418f43b9592978fff LLC currently allows users to inject raw frames, including IP packets encapsulated in SNAP. While Linux doesn't handle IP over SNAP, other systems do. Restrict LLC sockets to root similar to packet sockets.
