https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=283426 --- Comment #16 from Kristof Provost <kp@freebsd.org> --- Thanks for that test case, it was extremely helpful. I see what's happening here now. The if_ovpn filter function calls m_unshare(), which allocates a new mbuf, but then decides it doesn't want the packet after all. That's normally fine, but we can't tell the caller that we've messed with the m pointer, so the caller continues with a now invalid mbuf pointer. I hope to propose a fix later today. -- You are receiving this mail because: You are the assignee for the bug.help
