sys: Use membar_release/acquire around reference drop.

This just goes through my recent reference count membar audit and
changes membar_exit to membar_release and membar_enter to
membar_acquire -- this should make everything cheaper on most CPUs
without hurting correctness, because membar_acquire is generally
cheaper than membar_enter.

sys: Membar audit around reference count releases.

If two threads are using an object that is freed when the reference
count goes to zero, we need to ensure that all memory operations
related to the object happen before freeing the object.

Using an atomic_dec_uint_nv(&refcnt) == 0 ensures that only one
thread takes responsibility for freeing, but it's not enough to
ensure that the other thread's memory operations happen before the
freeing.

Consider:

	  Thread A			  Thread B
	obj->foo = 42;			obj->baz = 73;
	mumble(&obj->bar);		grumble(&obj->quux);
	/* membar_exit(); */		/* membar_exit(); */
	atomic_dec -- not last		atomic_dec -- last
					/* membar_enter(); */
					KASSERT(invariant(obj->foo,
					    obj->bar));
					free_stuff(obj);

The memory barriers ensure that

	obj->foo = 42;
	mumble(&obj->bar);

in thread A happens before

	KASSERT(invariant(obj->foo, obj->bar));
	free_stuff(obj);

in thread B.  Without them, this ordering is not guaranteed.

So in general it is necessary to do

	membar_exit();
	if (atomic_dec_uint_nv(&obj->refcnt) != 0)
		return;
	membar_enter();

to release a reference, for the `last one out hit the lights' style
of reference counting.  (This is in contrast to the style where one
thread blocks new references and then waits under a lock for existing
ones to drain with a condvar -- no membar needed thanks to mutex(9).)

I searched for atomic_dec to find all these.  Obviously we ought to
have a better abstraction for this because there's so much copypasta.
This is a stop-gap measure to fix actual bugs until we have that.  It
would be nice if an abstraction could gracefully handle the different
styles of reference counting in use -- some years ago I drafted an
API for this, but making it cover everything got a little out of hand
(particularly with struct vnode::v_usecount) and I ended up setting
it aside to work on psref/localcount instead for better scalability.

I got bored of adding #ifdef __HAVE_ATOMIC_AS_MEMBAR everywhere, so I
only put it on things that look performance-critical on 5sec review.
We should really adopt membar_enter_preatomic/membar_exit_postatomic
or something (except they are applicable only to atomic r/m/w, not to
atomic_load/store_*, making the naming annoying) and get rid of all
the ifdefs.

Rename min/max -> uimin/uimax for better honesty.

These functions are defined on unsigned int.  The generic name
min/max should not silently truncate to 32 bits on 64-bit systems.
This is purely a name change -- no functional change intended.

HOWEVER!  Some subsystems have

	#define min(a, b)	((a) < (b) ? (a) : (b))
	#define max(a, b)	((a) > (b) ? (a) : (b))

even though our standard name for that is MIN/MAX.  Although these
may invite multiple evaluation bugs, these do _not_ cause integer
truncation.

To avoid `fixing' these cases, I first changed the name in libkern,
and then compile-tested every file where min/max occurred in order to
confirm that it failed -- and thus confirm that nothing shadowed
min/max -- before changing it.

I have left a handful of bootloaders that are too annoying to
compile-test, and some dead code:

cobalt ews4800mips hp300 hppa ia64 luna68k vax
acorn32/if_ie.c (not included in any kernels)
macppc/if_gm.c (superseded by gem(4))

It should be easy to fix the fallout once identified -- this way of
doing things fails safe, and the goal here, after all, is to _avoid_
silent integer truncations, not introduce them.

Maybe one day we can reintroduce min/max as type-generic things that
never silently truncate.  But we should avoid doing that for a while,
so that existing code has a chance to be detected by the compiler for
conversion to uimin/uimax without changing the semantics until we can
properly audit it all.  (Who knows, maybe in some cases integer
truncation is actually intended!)

  kmem_alloc() with KM_SLEEP
  kmem_zalloc() with KM_SLEEP
  percpu_alloc()
  pserialize_create()
  psref_class_create()

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

C99 section 6.7.2.3 (Tags) Note 3 states that:

  A type specifier of the form

	enum identifier

  without an enumerator list shall only appear after the type it
  specifies is complete.

which means that we cannot pass an "enum vtype" argument to
kauth_access_action() without fully specifying the type first.
Unfortunately there is a complicated include file loop which
makes that difficult, so convert this minimal function into a
macro (and capitalize it).

Implement the register/deregister/evaluation API for secmodel(9). It
allows registration of callbacks that can be used later for
cross-secmodel "safe" communication.

When a secmodel wishes to know a property maintained by another
secmodel, it has to submit a request to it so the other secmodel can
proceed to evaluating the request. This is done through the
secmodel_eval(9) call; example:

    bool isroot;
    error = secmodel_eval("org.netbsd.secmodel.suser", "is-root",
        cred, &isroot);
    if (error == 0 && !isroot)
            result = KAUTH_RESULT_DENY;

This one asks the suser module if the credentials are assumed to be root
when evaluated by suser module. If the module is present, it will
respond. If absent, the call will return an error.

Args and command are arbitrarily defined; it's up to the secmodel(9) to
document what it expects.

Typical example is securelevel testing: when someone wants to know
whether securelevel is raised above a certain level or not, the caller
has to request this property to the secmodel_securelevel(9) module.
Given that securelevel module may be absent from system's context (thus
making access to the global "securelevel" variable impossible or
unsafe), this API can cope with this absence and return an error.

We are using secmodel_eval(9) to implement a secmodel_extensions(9)
module, which plugs with the bsd44, suser and securelevel secmodels
to provide the logic behind curtain, usermount and user_set_cpu_affinity
modes, without adding hooks to traditional secmodels. This solves a
real issue with the current secmodel(9) code, as usermount or
user_set_cpu_affinity are not really tied to secmodel_suser(9).

The secmodel_eval(9) is also used to restrict security.models settings
when securelevel is above 0, through the "is-securelevel-above"
evaluation:
- curtain can be enabled any time, but cannot be disabled if
securelevel is above 0.
- usermount/user_set_cpu_affinity can be disabled any time, but cannot
be enabled if securelevel is above 0.

Regarding sysctl(7) entries:
curtain and usermount are now found under security.models.extensions
tree. The security.curtain and vfs.generic.usermount are still
accessible for backwards compat.

Documentation is incoming, I am proof-reading my writings.

XXX might consider va0 mapping too.

XXX Having a secmodel(9) specific printf (like aprint_*) for reporting
secmodel(9) errors might be a good idea, but I am not sure on how
to design such a function right now.

Merge proc::p_mutex and proc::p_smutex into a single adaptive mutex, since
we no longer need to guard against access from hardware interrupt handlers.

Additionally, if cloning a process with CLONE_SIGHAND, arrange to have the
child process share the parent's lock so that signal state may be kept in
sync. Partially addresses PR kern/37437.

Simplify the interfaces needed for sys_setgroups() and sys_getgroups().
Exposed that the kauth code holds groups in an array, but removes some

Allows the syscall code to copyin/out directly to/from the cred structure,
this save a lot of faffing about with malloc/free even when compat code
has to use 16bit groups.

Add a new scope, the credentials scope, which is internal to the kauth(9)
implementation and meant to be used by security models to hook credential
related operations (init, fork, copy, free -- hooked in kauth_cred_alloc(),
kauth_proc_fork(), kauth_cred_clone(), and kauth_cred_free(), respectively)
and document it.

Add specificdata to credentials, and routines to register/deregister new
"keys", as well as set/get routines. This allows security models to add
their own private data to a kauth_cred_t.

The above two, combined, allow security models to control inheritance of
their own private data in credentials which is a requirement for doing
stuff like, I dunno, capabilities?

Introduce a new flag we mark as TRUE when we load listeners, and change
the logic in kauth_authorize_action() to use it.

When we try to authorize a request and the flag is FALSE, it means a
kernel was compiled with no listeners (or we're in very early boot stages),
and we always allow the request because it's likely to be coming from the
kernel itself or from loading an LKM with the security model (later on).

Assert that if the "listeners have been loaded" flag is FALSE, there are
really no listeners for the scope we're authorizing on.

When the flag is TRUE (ie., listeners have been loaded) but they were
later removed, creating a scope with no listeners, the request will be
denied further down.

This allows us to have the security model compiled outside the NetBSD
kernel and later loaded as an LKM, without fearing an attack will just
remove listeners we loaded earlier to create a "fail open" situation.

First take at security model abstraction.

- Add a few scopes to the kernel: system, network, and machdep.

- Add a few more actions/sub-actions (requests), and start using them as
  opposed to the KAUTH_GENERIC_ISSUSER place-holders.

- Introduce a basic set of listeners that implement our "traditional"
  security model, called "bsd44". This is the default (and only) model we
  have at the moment.

- Update all relevant documentation.

- Add some code and docs to help folks who want to actually use this stuff:

  * There's a sample overlay model, sitting on-top of "bsd44", for
    fast experimenting with tweaking just a subset of an existing model.

    This is pretty cool because it's *really* straightforward to do stuff
    you had to use ugly hacks for until now...

  * And of course, documentation describing how to do the above for quick
    reference, including code samples.

All of these changes were tested for regressions using a Python-based
testsuite that will be (I hope) available soon via pkgsrc. Information
about the tests, and how to write new ones, can be found on:

	http://kauth.linbsd.org/kauthwiki

NOTE FOR DEVELOPERS: *PLEASE* don't add any code that does any of the
following:

  - Uses a KAUTH_GENERIC_ISSUSER kauth(9) request,
  - Checks 'securelevel' directly,
  - Checks a uid/gid directly.

(or if you feel you have to, contact me first)

This is still work in progress; It's far from being done, but now it'll
be a lot easier.

Many thanks to YAMAMOTO Takashi, Matt Thomas, and Christos Zoulas for help
stablizing kauth(9).

Full credit for the regression tests, making sure these changes didn't break
anything, goes to Matt Fleming and Jaime Fournier.

Happy birthday Randi! :)

Short-circuit calls to kauth_authorize_action() for a scope withtout any
listeners to always return "allow".

The idea is that it's not entirely unlikely that some vendors, or users,
will decide to load the security model as an LKM, and that can only
happen after at least mounting local file-systems. If we would not have
this fast-path, all authorization requests would be denied.

The UID_MAX limit is not enforced by syscalls such as setreuid(2),
so I remove the assertion uid >= 0 && uid <= UID_MAX.  This squashes
a bug where Quagga would panic my machine by passing a UID outside
the range [0, UID_MAX].

AFAICT, this restores the historical (pre-kauth) behavior.

It is likely that GIDs do not satisfy the assertion gid >= 0 &&
gid <= GID_MAX, so remove that, too.

Patch from elad.
