mbuf: avoid assertion failure when splitting mbuf cluster
From OpenBSD:
commit 7b4d35e0a60ba1dd4daf4b1c2932020a22463a89
Author: bluhm <bluhm@openbsd.org>
Date: Fri Oct 20 16:25:15 2023 +0000
Avoid assertion failure when splitting mbuf cluster.
m_split() calls m_align() to initialize the data pointer of newly
allocated mbuf. If the new mbuf will be converted to a cluster,
this is not necessary. If additionally the new mbuf is larger than
MLEN, this can lead to a panic.
Only call m_align() when a valid m_data is needed. This is the
case if we do not refecence the existing cluster, but memcpy() the
data into the new mbuf.

mbuf(9): New m_get_n, m_gethdr_n. m_get_n(how, type, alignbytes, nbytes) returns an mbuf with no packet header having space for nbytes, with an internal buffer pointer aligned by alignbytes (typically ETHER_ALIGN or similar, if not zero). m_gethdr_n(how, type, alignbytes, nbytes) does the same but for an mbuf with a packet header. These return NULL on failure, which can happen either: (a) because how is M_DONTWAIT and allocating memory would sleep, or (b) because alignbytes + nbytes > MCLBYTES. On exit, m_len is set to nbytes, as is m_pkthdr.len for m_gethdr_n. These should be used to systematically replace all calls to m_get, m_gethdr, MGET, MGETHDR, and m_getcl. Most calls to m_clget and MCLGET will probably evaporate as a consequence. Proposed on tech-net last year: https://mail-index.netbsd.org/tech-net/2022/07/16/msg008285.html

kern: Eliminate most __HAVE_ATOMIC_AS_MEMBAR conditionals. I'm leaving in the conditional around the legacy membar_enters (store-before-load, store-before-store) in kern_mutex.c and in kern_lock.c because they may still matter: store-before-load barriers tend to be the most expensive kind, so eliding them is probably worthwhile on x86. (It also may not matter; I just don't care to do measurements right now, and it's a single valid and potentially justifiable use case in the whole tree.) However, membar_release/acquire can be mere instruction barriers on all TSO platforms including x86, so there's no need to go out of our way with a bad API to conditionalize them. If the procedure call overhead is measurable we just could change them to be macros on x86 that expand into __insn_barrier.

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.

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.

Move m_align() back into the kernel, and switch M_ALIGN and MH_ALIGN to it. Forcing a distinction between M_ALIGN and MH_ALIGN is too bug-friendly and serves no particular purpose.

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!)

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.

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.

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.

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).

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.

Check MT_FREE by default, and not just under DEBUG (or DIAGNOSTIC). This 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.

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.

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 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.

Pull up following revision(s) (requested by bouyer in ticket #674): sys/kern/uipc_mbuf.c: revision 1.132 m_split0(): If the newly allocated mbuf holds only the header, don't forget to set m_len to 0. Otherwise whatever will compute the size of this chain (including s_split() itself if called again on this chain) will get it wrong, leading to various issues. Bug exposed by the NFS server code with linux clients using TCP mounts.

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.

Add two new mbuf routines: * m_apply(), which applies a function to each mbuf in chain starting at a specified offset, for a specified length. * m_getptr(), which returns a pointer to the mbuf, as well as the offset into that mbuf, corresponding to an offset from the beginning of an mbuf chain. From OpenBSD, cleaned up slightly by me.

* 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). Part 2 in a series of simple patches contributed by Wasabi Systems to improve network performance.

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. From art@openbsd.org.

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" in the Solaris SLAB allocator).

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.

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>.
