This is intended to be used by people upgrading from single-IP jails to multi-IP jails but not having to change firewall rules, application ACLs, ... but to force their connections (unless otherwise changed) to the primry jail IP they had been used for years, as well as for people prefering to implement similar policies. Note that for IPv6, if configured incorrectly, this might lead to scope violations, which single-IPv6 jails could as well, as by the design of jails. [1] Note that in contrast to FreeBSD 8.x and newer, where we have per-jail options, the sysctls are global for all jails.

New Revision: 203047
URL: http://svn.freebsd.org/changeset/base/203047

Log:
  MFC 195820, 195940, 196643, 197663, 199067, 199215, and 199253:
  Optimize the cache flushing done when changing caching attributes of pages
  by doing nothing for CPUs that support self-snooping and using CLFLUSH
  instead of a full cache invalidate when possible.
  - On i386 take care of possible mappings of the page by sf buffer by
    utilizing the mapping for clflush, otherwise map the page transiently.
    Amd64 uses the direct map.
  - Do not use CLFLUSH on Intel CPUs due to problems with flushing the local
    APIC range by default.  This can be further controlled via the
    hw.clflush_disable loader tunable.  A setting of 1 disables the
    use of CLFLUSH.  A setting of 0 allows CLFLUSH to be used for Intel
    CPUs when CPUID_SS is not present.

Log:
  Synch with head: avoid namespace collisions (r177447), plug resource leak
  in FTP code (r199801), add support for HTTP (r202613, r202623, r203028).
  Also record mergeinfo for previously merged patches (r174752, r174588).
