DragonFlyBSD

If someone has spare cycles to tackle this, I'd really appreciate it. I won't bore you with the details, but it's forcing me to run a builder process that I have no control over in a DF instance on a VM and I'd like to move it to a dedicated physical machine.

The getfsstat() count problem as you reported can be seen from the different counts shown by mount(8) and lsvfs(1), and the main reason is due to the chroot from the initrd temporary root into the real root.

Please see more information in my email: http://lists.dragonflybsd.org/pipermail/users/2018-June/335759.html

Cheers,
Aaron

I think the problem is this commit: https://gitweb.dragonflybsd.org/dragonfly.git/commit/75ffff0d6f3520361771d057b364af7f81ebb36f

It checks for mount visibility when sfsp is uaf->buf, but doesn't when sfsp is null.

Issue #2926 has been updated by t_dfbsd.

I think the problem is this commit: https://gitweb.dragonflybsd.org/dragonfly.git/commit/75ffff0d6f3520361771d057b364af7f81ebb36f

Not related this issue itself, but none of the filesystems added to
DragonFly after this commit (hammer1, devfs, tmpfs, hammer2, autofs,
etc) do what this commit says filesystems should do.
It's not a must anyway.

It checks for mount visibility when sfsp is uaf->buf, but doesn't when sfsp is null.
