[bisected] Forwarded packets occasionally has loopback output interface in Netfilter

2017-12-26 Thread Anders K. Pedersen | Cohaesio
Hello, On one of our border routers, Netfilter is occasionally logging packets with "OUT=lo" (output interface lo) even though the packet should be going out via a regular interface. This behavior is present on Linux 4.13.0 to 4.14.9, and a bisection of the problem points to [95c47f9cf5e028d1ae77

general protection fault in dst_destroy() - 4.13.9

Hello, A few days ago, one of our routers (running Linux 4.13.9) crashed due to a general protection fault in dst_destroy(). At the time, it had run for several weeks without any problems, but then crashed three times in a row within a few minutes - all due to a general protection fault at dst_des
