https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D238870 --- Comment #7 from Kristof Provost <kp@freebsd.org> --- Created attachment 205530 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D205530&action= =3Dedit ifp_dying.patch A second experimental patch. This solves a different problem, that also manifests during the pf tests. It looks like there's a race, where the epair deletes its ifp while the jail shuts down. The jail shutdown moves the ifp back into its original vnet, wh= ile the epair delete is causing it to be deleted. As a result we end up with a freed ifp in V_ifnet, and when we run into it later the box panics. I think this is likely fallout from the epoch-ification, so mmacy@ should t= ake a look at this. --=20 You are receiving this mail because: You are the assignee for the bug.=
