ffb079be0c Implement user-setable promiscuous mode (a new `promisc' flag for ifconfig(8)).
Also, for all interfaces in this mode pass all ethernet frames to upper layer,
even those not addressed to our own MAC, which allows packets encapsulated
in those frames be processed with packet filters (ipfw(8) et al).

62f7648682 Increase size of ifnet.if_flags from 16 bits (short) to 32 bits (int). To avoid
breaking application ABI use unused ifreq.ifru_flags[1] for upper 16 bits in
SIOCSIFFLAGS and SIOCGIFFLAGS ioctl's.

8f293a63ce Introduce support for Mandatory Access Control and extensible
kernel access control.

Introduce two ioctls, SIOCGIFMAC, SIOCSIFMAC, which permit user
processes to manage the MAC labels on network interfaces.  Note
that this is part of the user process API/ABI that will be revised
prior to 5.0-RELEASE.

e70cd26366 Introduce support for Mandatory Access Control and extensible
kernel access control.

Instrument the interface management code so that MAC labels are
properly maintained on network interfaces (struct ifnet).  In
particular, invoke entry points when interfaces are created and
removed.  MAC policies may initialized the label interface based
on a variety of factors, including the interface name.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

b2c08f43d0 When the local link address is changed, send out gratuitous ARPs
to notify other nodes about the address change. Otherwise, they
might try and keep using the old address until their arp table
entry times out and the address is refreshed.

Maybe this ought to be done for INET6 addresses as well but i have
no idea how to do it. It should be pretty straightforward though.

8071913df2 Pull post-4.4BSD change to sys/net/route.c from BSD/OS 4.2.
Have sys/net/route.c:rtrequest1(), which takes ``rt_addrinfo *''
as the argument.  Pass rt_addrinfo all the way down to rtrequest1
and ifa->ifa_rtrequest.  3rd argument of ifa->ifa_rtrequest is now
``rt_addrinfo *'' instead of ``sockaddr *'' (almost noone is
using it anyways).

Benefit: the following command now works.  Previously we needed
two route(8) invocations, "add" then "change".
# route add -inet6 default ::1 -ifp gif0

Remove unsafe typecast in rtrequest(), from ``rtentry *'' to
``sockaddr *''.  It was introduced by 4.3BSD-Reno and never
corrected.

There are many many changes since last KAME merge.

TODO:
  - The definitions of SADB_* in sys/net/pfkeyv2.h are still different
    from RFC2407/IANA assignment because of binary compatibility
    issue.  It should be fixed under 5-CURRENT.
  - ip6po_m member of struct ip6_pktopts is no longer used.  But, it
    is still there because of binary compatibility issue.  It should
    be removed under 5-CURRENT.

91421ba234 o Move per-process jail pointer (p->pr_prison) to inside of the subject
credential structure, ucred (cr->cr_prison).
o Allow jail inheritence to be a function of credential inheritence.
o Abstract prison structure reference counting behind pr_hold() and
  pr_free(), invoked by the similarly named credential reference
  management functions, removing this code from per-ABI fork/exit code.
o Modify various jail() functions to use struct ucred arguments instead
  of struct proc arguments.
o Introduce jailed() function to determine if a credential is jailed,
  rather than directly checking pointers all over the place.
o Convert PRISON_CHECK() macro to prison_check() function.
o Move jail() function prototypes to jail.h.
o Emulate the P_JAILED flag in fill_kinfo_proc() and no longer set the
  flag in the process flags field itself.
o Eliminate that "const" qualifier from suser/p_can/etc to reflect
  mutex use.

Notes:

o Some further cleanup of the linux/jail code is still required.
o It's now possible to consider resolving some of the process vs
  credential based permission checking confusion in the socket code.
o Mutex protection of struct prison is still not present, and is
  required to protect the reference count plus some fields in the
  structure.
