Hannes Frederic Sowa 787d7ac308 udp: restrict offloads to one namespace ... udp tunnel offloads tend to aggregate datagrams based on inner headers. gro engine gets notified by tunnel implementations about possible offloads. The match is solely based on the port number. Imagine a tunnel bound to port 53, the offloading will look into all DNS packets and tries to aggregate them based on the inner data found within. This could lead to data corruption and malformed DNS packets. While this patch minimizes the problem and helps an administrator to find the issue by querying ip tunnel/fou, a better way would be to match on the specific destination ip address so if a user space socket is bound to the same address it will conflict.
