            Bug ID: 189385
           Summary: [iOS] Move default mach-lookup deny to after common.sb
                    is imported
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit2
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: bfulgham at webkit.org

The default deny rule in our iOS sandboxes happens before we import common.sb, which potentially allows more things than we would prefer in the WebContent, Storage, or Network processes.

Instead, we should first import 'common.sb', then deny all lookups so we can be sure we only enable the items we absolutely need to function.
