            Bug ID: 296550
           Summary: resvport/noresvport /etc/export  options
           Product: Base System
           Version: Unspecified
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: lionelcons1972@gmail.com

I would be preferable to have a resvport (and noresvport) export
option on a per-export basis to choose whether mounts from UDP/TCP
ports >= 1024 are allowed or not, overriding any kernel default.

While it is desired to keep the current default, it might be useful to
allow UDP/TCP ports on a per-export basis to make access from systems
behind NAT (e.g. VMs) easier.

This mirrors the same "resvport" export option as found in
Solaris/Illumos, and the "insecure" export option as found in Linux.
