Since global parts appeared to be only mutex initializations, just abandon them and use MTX_SYSINIT() instead. Kill my incorrect VNET_FOREACH() iterator and instead use correct approach with VNET_SYSINIT().

The 3 commits apply cleanly to stable/10 and seem to work (but I have only tested it lightly so far) (In reply to darius from comment #18) I'm OK with merging this to stable/10, but I would like to get some feedback from PF users on the state of things in CURRENT before merging. What is your experience with this patch? Herbert Skuhra has provided good feedback, but getting a few more people to try it and report would be great. Herbert found another bug in CURRENT: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195859 That is a bug in the bridge code, and not part of the VIMAGE + PF fixes. However, all this stuff is interrelated. It would be nice to get a fix in for PR 195859, so provide a consistent testing environment for VIMAGE in CURRENT. That will make it easier to backport patches to stable/10. Updated 10.1-BETA and 10.1-RC versioned bugs to 10.1-STABLE. Is there any update on these fixes? I've just happened to bump my 10.1-RELEASE into 10-STABLE and created few VIMAGE based jails. As soon as I stop any of them, and I can reproduce it every time, the host OS crashes. That makes the entire VIMAGE completely unusable... The commits done under https://svnweb.freebsd.org/changeset/base/276756 were backed out in https://svnweb.freebsd.org/changeset/base/277519 . Nikos is working on another patch https://reviews.freebsd.org/D1944 It seems the problem was fixed with r302156 before stable/11 was branched but never merged to stable/10. vnet is now supported in 12.0 (but not in earlier releases). Many vent-related problems were fixed in pf (and pf-in-vnet-jails is now part of our automated tests). Please re-open it if you're still having issues on 12 or later. |
