All,
I=E2=80=99m running jails and bhyve using netgraph bridge. The jails are =
using Devin Teske=E2=80=99s jng and I have adapted iohyve to use the =
same netgraph bridge.
I haven=E2=80=99t had any panic=E2=80=99s after applying revisions =
306684, 312943, 315131, 315469, 307235, 313001, 315136 and 315741.
Can someone please MFC them to 11-stable?
I=E2=80=99m starting and stopping jails in a continous loop. I have =
added some extra code to track an occasional panic in =
pf_purge_expired_states, but so far no luck.
I also have a change in zone_release to fix another panic and leak in =
slab_free_item. The issue is that zone_release tries to release a keg =
that never belonged to the zone it is trying to release. With my limited =
knowledge, i think that should not happen.
