and only then proceed to processing each request.
Add a KAUTH_PROCESS_CANSEE call right after pfind(). This should really
be done differently, so mark it with XXX.
requests and centralizing them all. The result is that some of these
are not used on some architectures, but the documentation was updated
to reflect that.
- makes sysctl_proc_find() just lookup the process,
- use KAUTH_PROCESS_CANSEE requests to determine if the caller is
allowed to view the target process' corename, stop flags, and
rlimits,
- use explicit kauth(9) calls with KAUTH_PROCESS_CORENAME,
KAUTH_REQ_PROCESS_RESOURCE_NICE, KAUTH_REQ_PROCESS_RESOURCE_RLIMIT,
and KAUTH_PROCESS_STOPFLAG when modifying the aforementioned.
- sync man-page and example skeleton secmodel with reality.

this is a pullup candidate.
First, remove process_checkioperm() calls from MD code. Similar checks
using kauth(9) routines (on the process scope, using appropriate action)
are done in the callers.
Add secmodel back-end to handle each subsystem.

allowed. It takes three int * arguments indicating domain, type, and
protocol. Replace previous KAUTH_REQ_NETWORK_SOCKET_RAWSOCK with it (but
keep it still).
Places that used to explicitly check for privileged context now don't
need it anymore, so I replaced these with XXX comment indiacting it for
future reference.
Documented and updated examples as well.
used to manage network interfaces.
Add four sub-actions to fulfill generic needs for now, until a more
carefully defined usage of the interface is documented: get, set,
getpriv, and setpriv.
credentials on sockets, at least not anytime soon, this is a way to check
if we can "look" at a socket. Later on when (and if) we do have socket
credentials, the interface usage remains the same because we pass the
socket.
This also fixes sysctl for inet/inet6 pcblist.
It uses an authorization wrapper per device class on the system to
ensure type-safety.
For now, it supports only terminal (TTY) devices, and has two actions
for them: "open terminal" and "privileged set". Sample usage has been
added to i386 and hp300 code for reference.
Update documentation.
to do with the security model used. Move back the call to spec_open(),
which can now return the real return value from vfs_mountedon() (EBUSY)
and not EPERM, changing semantics.
