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.

awge: fix issue that caused rx packets to be corrupt with DIAGNOSTIC kernel

It seems the hardware can only reliably do rx DMA to addresses that are
dcache size aligned. This is hinted at by some GMAC data sheets but hard to
find an authoritative source.

on non-DIAGNOSTIC kernels we always implicitly get MCLBYTES-aligned mbuf
data pointers, but with the reintroduction of POOL_REDZONE for DIAGNOSTIC
we can get 8-byte alignment due to redzone padding. So align rx pointers to
64 bytes which should be good for both arm32 and aarch64.
While here change some bus_dmamap_load() to bus_dmamap_load_mbuf() and add
one missing bus_dmamap_sync(). Also fixes the code to not assume that
MCLBYTES == AWGE_MAX_PACKET. User may override MCLSHIFT in kernel config.
correct pointer arithmetics

mcl_cache: align items to COHERENCY_UNIT

Because we do cache incoherent DMA to/from mbufs we cannot safely share
share cache lines with adjacent items that may be concurrently accessed.

awge: drop redundant m_adj(). Handled via uipc_mbuf.c r1.235 instead.

Mask all the MMC counter interrupts if the MMC module is present.

change m_defrag() to coalesce the chain to single mbuf if it's short enough
and first mbuf doesn't use external storage

most fragmented packets end up with first short mbuf containing
frame + protocol header only, and second mbuf containing the data;
m_defrag() previously always returned chain of at least two mbufs,
now it should actually return all data in single mbuf for typical
mbuf chain with length < MCLBYTES

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!)

Revert my rev1.190, remove the M_READONLY check. The initial code was
correct: what is read-only is the mbuf storage, not the mbuf itself. The
storage contains the packet payload, and never has anything related to
mbufs. So it is fine to remove M_PKTHDR on mbufs that have a read-only
storage.

In fact it was kind of obvious, since several places already manually
remove M_PKTHDR without taking care of the external storage.

Modify m_defrag, so that it never frees the first mbuf of the chain. While
here use the given 'flags' argument, and not M_DONTWAIT.

We have a problem with several drivers: they poll an mbuf chain from their
queues and call m_defrag on them, but m_defrag could update the mbuf
pointer, so the mbuf in the queue is no longer valid. It is not easy to
fix each driver, because doing pop+push will reorder the queue, and we
don't really want that to happen.

This problem was independently spotted by me, Kengo, Masanobu, and other
people too it seems (perhaps PR/53218).

Now m_defrag leaves the first mbuf in place, and compresses the chain
only starting from the second mbuf in the chain.

It is important not to compress the first mbuf with hacks, because the
storage of this first mbuf may be shared with other mbufs.

Introduce a m_verify_packet function, that verifies the mbuf chain of a
packet to ensure it is not malformed. Call this function in "points of
interest", that are the IPv4/IPv6/IPsec entry points. There could be more.

We use M_VERIFY_PACKET(m), declared under DIAGNOSTIC only.

This function should not be called everywhere, especially not in places
that temporarily manipulate (and clobber) the mbuf structure; once they're
done they put the mbuf back in a correct format.

Remove M_PKTHDR from secondary mbufs when reassembling packets.

This is a real problem, because I found at least one component that relies
on the fact that only the first mbuf has M_PKTHDR: far from here, in
m_splithdr, we don't update m->m_pkthdr.len if M_PKTHDR is found in a
secondary mbuf. (The initial intention there was to avoid updating
m_pkthdr.len twice, the assumption was that if M_PKTHDR is set then we're
dealing with the first mbuf.) Therefore, when handling fragmented IPsec
packets (in particular IPv6, IPv4 is a bit more complicated), we may end
up with an incorrect m_pkthdr.len after authentication or decryption. In
the case of ESP, this can lead to a remote crash on this instruction:
        m_copydata(m, m->m_pkthdr.len - 3, 3, lastthree);
m_pkthdr.len is bigger than the actual mbuf chain.

It seems possible to me to trigger this bug even if you don't have the ESP
key, because the fragmentation part is outside of the encrypted ESP
payload.

So if you MITM the target, and intercept an incoming ESP packet (which you
can't decrypt), you should be able to forge a new specially-crafted,
fragmented packet and stuff the ESP payload (still encrypted, as you
intercepted it) into it. The decryption succeeds and the target crashes.

Allow only one pending call to a pool's backing allocator at a time.
Candidate fix for problems with hanging after kva fragmentation related
to PR kern/45718.

Proposed on tech-kern:
https://mail-index.NetBSD.org/tech-kern/2017/10/23/msg022472.html
Tested by bouyer@ on i386.

This makes one small change to the semantics of pool_prime and
pool_setlowat: they may fail with EWOULDBLOCK instead of ENOMEM, if
there is a pending call to the backing allocator in another thread but
we are not actually out of memory.  That is unlikely because nearly
always these are used during initialization, when the pool is not in
use.

Define the new flag too for previous commit.

pool_grow can now fail even when sleeping is ok. Catch this case in pool_get
and retry.

Assert that pool_get failure happens only with PR_NOWAIT.
This would have caught the mistake I made last week leading to null
pointer dereferences all over the place, a mistake which I evidently
poorly scheduled alongside maxv's change to the panic message on x86
for null pointer dereferences.

Since pr_lock is now used to wait for two things now (PR_GROWING and
PR_WANTED) we need to loop for the condition we wanted.
make the KASSERTMSG/panic strings consistent as '%s: [%s], __func__, wchan'
Handle the ERESTART case from pool_grow()

don't pass 0 to the pool flags
Guess pool_cache_get(pc, 0) means PR_WAITOK here.
Earlier on in the same context we use kmem_alloc(sz, KM_SLEEP).

use PR_WAITOK everywhere.
use PR_NOWAIT.

Don't use 0 for PR_NOWAIT

use PR_NOWAIT instead of 0

panic ex nihilo -- PR_NOWAITing for zerot

Add assertions that either PR_WAITOK or PR_NOWAIT are set.
- fix an assert; we can reach there if we are nowait or limitfail.
- when priming the pool and failing with ERESTART, don't decrement the number
  of pages; this avoids the issue of returning an ERESTART when we get to 0,
  and is more correct.
- simplify the pool_grow code, and don't wakeup things if we ENOMEM.

In pmap_enter_ma(), only try to allocate pves if we might need them,
and even if that fails, only fail the operation if we later discover
that we really do need them.  This implements the requirement that
pmap_enter(PMAP_CANFAIL) must not fail when replacing an existing
mapping with the first mapping of a new page, which is an unintended
consequence of the changes from the rmind-uvmplock branch in 2011.

The problem arises when pmap_enter(PMAP_CANFAIL) is used to replace an existing
pmap mapping with a mapping of a different page (eg. to resolve a copy-on-write).
If that fails and leaves the old pmap entry in place, then UVM won't hold
the right locks when it eventually retries.  This entanglement of the UVM and
pmap locking was done in rmind-uvmplock in order to improve performance,
but it also means that the UVM state and pmap state need to be kept in sync
more than they did before.  It would be possible to handle this in the UVM code
instead of in the pmap code, but these pmap changes improve the handling of
low memory situations in general, and handling this in UVM would be clunky,
so this seemed like the better way to go.

This somewhat indirectly fixes PR 52706, as well as the failing assertion
about "uvm_page_locked_p(old_pg)".  (but only on x86, various other platforms
will need their own changes to handle this issue.)
In uvm_fault_upper_enter(), if pmap_enter(PMAP_CANFAIL) fails, assert that
the pmap did not leave around a now-stale pmap mapping for an old page.
If such a pmap mapping still existed after we unlocked the vm_map,
the UVM code would not know later that it would need to lock the
lower layer object while calling the pmap to remove or replace that
stale pmap mapping.  See PR 52706 for further details.
hopefully workaround the irregularly "fork fails in init" problem.
if a pool is growing, and the grower is PR_NOWAIT, mark this.
if another caller wants to grow the pool and is also PR_NOWAIT,
busy-wait for the original caller, which should either succeed
or hard-fail fairly quickly.

implement the busy-wait by unlocking and relocking this pools
mutex and returning ERESTART.  other methods (such as having
the caller do this) were significantly more code and this hack
is fairly localised.
ok chs@ riastradh@

Don't release the lock in the PR_NOWAIT allocation. Move flags setting
after the acquiring the mutex. (from Tobias Nygren)
apply the change from arch/x86/x86/pmap.c rev. 1.266 commitid vZRjvmxG7YTHLOfA:

In pmap_enter_ma(), only try to allocate pves if we might need them,
and even if that fails, only fail the operation if we later discover
that we really do need them.  If we are replacing an existing mapping,
reuse the pv structure where possible.

This implements the requirement that pmap_enter(PMAP_CANFAIL) must not fail
when replacing an existing mapping with the first mapping of a new page,
which is an unintended consequence of the changes from the rmind-uvmplock
branch in 2011.

The problem arises when pmap_enter(PMAP_CANFAIL) is used to replace an existing
pmap mapping with a mapping of a different page (eg. to resolve a copy-on-write).
If that fails and leaves the old pmap entry in place, then UVM won't hold
the right locks when it eventually retries.  This entanglement of the UVM and

instead of in the pmap code, but these pmap changes improve the handling of
low memory situations in general, and handling this in UVM would be clunky,
so this seemed like the better way to go.

This somewhat indirectly fixes PR 52706 on the remaining platforms where
this problem existed.

Don't use macros, rather inline, much clearer.

For the record, I was partly mistaken in my previous commit: even though
the macros were local, the function names were still the ones of the real
callers.

However, setting the name in m_data was not a good thing; this was a
valid pointer, and the kernel could execute a long time before figuring
out the mbuf was already freed - therefore making debugging more difficult.
And information on the caller can be obtained via ddb anyway.

code is fast, with an nonexistent overhead - and we already take care of
setting MT_FREE, so why not check it.

In addition, stop registering the function name, that's not helpful since
the MBUFFREE macro is local. Instead, set m_data to NULL, so that any
access to a freed mbuf's data after mtod() or similar will page fault.

The combination of these two changes provides a fast and efficient way of
detecting use-after-frees in the network stack.

Avoid storing a pointer of an interface in a mbuf

Having a pointer of an interface in a mbuf isn't safe if we remove big
kernel locks; an interface object (ifnet) can be destroyed anytime in any
packet processing and accessing such object via a pointer is racy. Instead
we have to get an object from the interface collection (ifindex2ifnet) via
an interface index (if_index) that is stored to a mbuf instead of an
pointer.

The change provides two APIs: m_{get,put}_rcvif_psref that use psref(9)
for sleep-able critical sections and m_{get,put}_rcvif that use
pserialize(9) for other critical sections. The change also adds another
API called m_get_rcvif_NOMPSAFE, that is NOT MP-safe and for transition
moratorium, i.e., it is intended to be used for places where are not
planned to be MP-ified soon.

The change adds some overhead due to psref to performance sensitive paths,
however the overhead is not serious, 2% down at worst.

Proposed on tech-kern and tech-net.

Introduce m_set_rcvif and m_reset_rcvif

The API is used to set (or reset) a received interface of a mbuf.
They are counterpart of m_get_rcvif, which will come in another
commit, hide internal of rcvif operation, and reduce the diff of
the upcoming change.

No functional change.

Protect ifnet list with psz and psref

The change ensures that ifnet objects in the ifnet list aren't freed during
list iterations by using pserialize(9) and psref(9).

Note that the change adds a pslist(9) for ifnet but doesn't remove the
original ifnet list (ifnet_list) to avoid breaking kvm(3) users. We
shouldn't use the original list in the kernel anymore.

Add init function for mbuf.

some functions use mbuf as stack variable instead of allocating by m_get().
They should use this function(s) to prevent access to uninitialized fields.

Currently, the mbuf stack allocating functions are the following.

      - bwi_rxeof()
      - bwi_encap()
    + sys/dev/ic/dp8390.c

- Rework NPF's nbuf interface: use advancing and ensuring as a main method.
  Eliminate unnecessary copy and simplify.  Adapt regression tests.
- Simplify ICMP ALG a little.  While here, handle ICMP ECHO for traceroute.
- Minor fixes, misc cleanup.
Silence gcc in npf_recache().
Add m_ensure_contig() routine, which is equivalent to m_pullup, but does not
destroy the mbuf chain on failure (it is kept valid).
- nbuf_ensure_contig: rework to use m_ensure_contig(9), which will not free
  the mbuf chain on failure.  Fixes some corner cases.  Improve regression
  test and sprinkle some asserts.
- npf_reassembly: clear nbuf on IPv6 reassembly failure path (partial fix).
  The problem was found and fix provided by Anthony Mallet.

Remove the unused 'struct malloc_type' args to kern_malloc/realloc/free
The M_xxx arg is left on the calls to malloc() and free(),
  maybe they could be converted to an enumeration and just saved in
  the malloc header (for deep diag use).
Remove the malloc_type from mbuf extension.
Fixes rump build as well.

Remove separate mb_map. The nmbclusters is computed at boot time based
on the amount of physical memory and limited by NMBCLUSTERS if present.
Architectures without direct mapping also limit it based on the kmem_map
size, which is used as backing store. On i386 and ARM, the maximum KVA
used for mbuf clusters is limited to 64MB by default.

The old default limits and limits based on GATEWAY have been removed.
key_registered_sb_max is hard-wired to a value derived from 2048
clusters.

Dynamic sysctl.

Gone are the old kern_sysctl(), cpu_sysctl(), hw_sysctl(),
vfs_sysctl(), etc, routines, along with sysctl_int() et al.  Now all
nodes are registered with the tree, and nodes can be added (or
removed) easily, and I/O to and from the tree is handled generically.

Since the nodes are registered with the tree, the mapping from name to
number (and back again) can now be discovered, instead of having to be
hard coded.  Adding new nodes to the tree is likewise much simpler --
the new infrastructure handles almost all the work for simple types,
and just about anything else can be done with a small helper function.

All existing nodes are where they were before (numerically speaking),
so all existing consumers of sysctl information should notice no
difference.

PS - I'm sorry, but there's a distinct lack of documentation at the
moment.  I'm working on sysctl(3/8/9) right now, and I promise to
watch out for buses.

* m_getptr(), which returns a pointer to the mbuf, as well as

  the beginning of an mbuf chain.

* Use a pool_cache constructor to record the physical address of mbufs
  in the mbuf header.
* Use the new cached paddr feature of the pool_cache API to record
  the physical address of mbuf clusters.  (We cannot use a ctor for
  clusters, since clusters have no constructed form; they are merely
  buffers).

Bus_dma back-ends may use the cached physical addresses to save having to
extract the physical address from virtual.

* Provide space in m_ext recording the vm_page *'s for an SOSEND_LOAN_CHUNK-
  sized non-cluster external buffer.  Use this in the sosend_loan code to
  save having to extract the physical address from virtual and then look
  up the vm_page *'s.

* Provide an indication that an external buffer is mapped read-only at
  the MMU.  Set this flag for the external buffer in the sosend_loan
  case, since loaned pages are always mapped read-only.  Bus_dma back-ends
  may use this information to save cache flushing, since a cache flush of
  a read-only mapping is redundant on some architectures (the cache would
  have already been flushed when making the mapping read-only).

Changes to allow the IPv4 and IPv6 layers to align headers themseves,
as necessary:
* Implement a new mbuf utility routine, m_copyup(), is is like
  m_pullup(), except that it always prepends and copies, rather
  than only doing so if the desired length is larger than m->m_len.
  m_copyup() also allows an offset into the destination mbuf, which
  allows space for packet headers, in the forwarding case.
* Add *_HDR_ALIGNED_P() macros for IP, IPv6, ICMP, and IGMP.  These
  macros expand to 1 if __NO_STRICT_ALIGNMENT is defined, so that
  architectures which do not have strict alignment constraints don't
  pay for the test or visit the new align-if-needed path.
* Use the new macros to check if a header needs to be aligned, or to
  assert that it already is, as appropriate.

Note: This code is still somewhat experimental.  However, the new
code path won't be visited if individual device drivers continue
to guarantee that packets are delivered to layer 3 already properly
aligned (which are rules that are already in use).

Pool deals fairly well with physical memory shortage, but it doesn't
deal with shortages of the VM maps where the backing pages are mapped
(usually kmem_map).  Try to deal with this:

* Group all information about the backend allocator for a pool in a
  separate structure.  The pool references this structure, rather than
  the individual fields.
* Change the pool_init() API accordingly, and adjust all callers.
* Link all pools using the same backend allocator on a list.
* The backend allocator is responsible for waiting for physical memory
  to become available, but will still fail if it cannot callocate KVA
  space for the pages.  If this happens, carefully drain all pools using
  the same backend allocator, so that some KVA space can be freed.
* Change pool_reclaim() to indicate if it actually succeeded in freeing
  some pages, and use that information to make draining easier and more
  efficient.
* Get rid of PR_URGENT.  There was only one use of it, and it could be
  dealt with by the caller.

a whole bunch of changes to improve performance and robustness under load:

 - remove special treatment of pager_map mappings in pmaps.  this is
   required now, since I've removed the globals that expose the address range.
   pager_map now uses pmap_kenter_pa() instead of pmap_enter(), so there's
   no longer any need to special-case it.
 - eliminate struct uvm_vnode by moving its fields into struct vnode.
 - rewrite the pageout path.  the pager is now responsible for handling the
   high-level requests instead of only getting control after a bunch of work
   has already been done on its behalf.  this will allow us to UBCify LFS,
   which needs tighter control over its pages than other filesystems do.
   writing a page to disk no longer requires making it read-only, which
   allows us to write wired pages without causing all kinds of havoc.
 - use a new PG_PAGEOUT flag to indicate that a page should be freed
   on behalf of the pagedaemon when it's unlocked.  this flag is very similar
   to PG_RELEASED, but unlike PG_RELEASED, PG_PAGEOUT can be cleared if the
   pageout fails due to eg. an indirect-block buffer being locked.
   this allows us to remove the "version" field from struct vm_page,
   and together with shrinking "loan_count" from 32 bits to 16,
   struct vm_page is now 4 bytes smaller.
 - no longer use PG_RELEASED for swap-backed pages.  if the page is busy
   because it's being paged out, we can't release the swap slot to be
   reallocated until that write is complete, but unlike with vnodes we
   don't keep a count of in-progress writes so there's no good way to
   know when the write is done.  instead, when we need to free a busy
   swap-backed page, just sleep until we can get it busy ourselves.
 - implement a fast-path for extending writes which allows us to avoid
   zeroing new pages.  this substantially reduces cpu usage.
 - encapsulate the data used by the genfs code in a struct genfs_node,
   which must be the first element of the filesystem-specific vnode data
   for filesystems which use genfs_{get,put}pages().
 - eliminate many of the UVM pagerops, since they aren't needed anymore
   now that the pager "put" operation is a higher-level operation.
 - enhance the genfs code to allow NFS to use the genfs_{get,put}pages
   instead of a modified copy.
 - clean up struct vnode by removing all the fields that used to be used by
   the vfs_cluster.c code (which we don't use anymore with UBC).
 - remove kmem_object and mb_object since they were useless.
   instead of allocating pages to these objects, we now just allocate
   pages with no object.  such pages are mapped in the kernel until they
   are freed, so we can use the mapping to find the page to free it.
   this allows us to remove splvm() protection in several places.

The sum of all these changes improves write throughput on my
decstation 5000/200 to within 1% of the rate of NetBSD 1.5
and reduces the elapsed time for "make release" of a NetBSD 1.5
source tree on my 128MB pc to 10% less than a 1.5 kernel took.

Use pool_cache_*() for mbufs and clusters.  While we don't use the
ctor/dtor feature, it's still faster to allocate from the cache groups
than it is from the pool (cache groups are analogous to "magazines"

introduce m->m_pkthdr.aux to hold random data which needs to be passed
between protocol handlers.

ipsec socket pointers, ipsec decryption/auth information, tunnel
decapsulation information are in my mind - there can be several other usage.
at this moment, we use this for ipsec socket pointer passing.  this will
avoid reuse of m->m_pkthdr.rcvif in ipsec code.

due to the change, MHLEN will be decreased by sizeof(void *) - for example,
for i386, MHLEN was 100 bytes, but is now 96 bytes.
we may want to increase MSIZE from 128 to 256 for some of our architectures.

take caution if you use it for keeping some data item for long period
of time - use extra caution on M_PREPEND() or m_adj(), as they may result
in loss of m->m_pkthdr.aux pointer (and mbuf leak).

this will bump kernel version.

More improvements to mbuf and mbuf cluster allocation:

- Initialize mbpool and mclpool with msize and mclbytes, respectively,
so that those values may be patched and have an actual affect on the
next system reboot.

- Set low water marks on mbpool (default: 16) and mclpool (default: 8).
This should be of great help for diskless systems, which need to allocate
mbufs in order to clean dirty pages; the low water marks increase the
chances of this being possible to do in memory starvation situations.

- Add support for getting/setting some mbuf-related parameters via sysctl.
* msize and mclsize (read-only)
* nmbclusters (read-only unless the platform has direct-mapped pool pages,
in which case the value can be increased).
* mblowat and mcllowat (read/write)

Set a hard limit (rather than an advisory high water mark for pages) of
NMBCLUSTERS for the mbuf cluster pool.  On platforms which use direct-mapped
segments for pool pages (MIPS and Alpha), this makes NMBCLUSTERS actually
meaningful (such ports don't even allocate mb_map, as it is not used to
map mbuf cluster pages).

Improve the message logged at a maximum rate of once per second.  The
new message: "WARNING: mclpool limit reached; increase NMBCLUSTERS".

In the back-end pool page allocator, remove the message about mb_map
being full.  The message was not necessarily correct as the allocator
may have been starved for pages, rather than for space in the map.  Also,
the hard limit on the mbuf cluster pool will be reached before the map
fills (the last cluster will always fit into the map), so the message
is redundant.

Add a comment in mbinit() about considering setting low water marks on
the mbuf and mbuf cluster pools.

Don't call the protocol drain routines if how == M_NOWAIT, which typically
means we're in interrupt context.  Since we can be called from a network

If we fail to allocate a cluster to hold a large packet, simply
drop it rather than using a chain of tiny mbufs.

Update and enhancement to the mbuf code, to support use of non-cluster
external storage.  Highlights:

	- additional "void *" argument to (*ext_free)(), an opaque
	  cookie for use by the free function.
	- MCLALLOC() and MCLFREE() calls are gone.  They are replaced
	  by MEXTADD() (add external storage to mbuf), MEXTMALLOC()
	  (malloc() external storage and attach to mbuf), and
	  MEXTREMOVE() (remove external storage from mbuf).
	- completely new external storage reference counting
	  mechanism; mclrefcnt[] is gone.

These changes will eventually be used to pass driver DMA buffers up
the network stack, and reduce/eliminate copies in certain code paths
(e.g. NFS writes).

From Matt Thomas <matt@3am-software.com> and myself <thorpej@nas.nasa.gov>,
with some input from Chris Demetriou <cgd@cs.cmu.edu> and review by
Charles Hannum <mycroft@mit.edu>.

if kmem_malloc() fails while trying to allocate an mbuf cluster, try
and free some space by calling m_reclaim().  Also, log the "mb_map full"
error message (at most) every 60-seconds.  The old code would log it
once over the lifetime of the system, but that's not a useful diagnostic.
(More useful is the new behaviour, which roughly indicates how often
periods of heavy load occur, without spamming the console and system
