+Highlights:
+.Pp
+.Bl -hyphen -compact
+.It
+Very competitive performance, with logarithmic time complexity on average.
+.It
+Lookups are lock-free and inserts/deletes are using fine-grained locking.
+.It
+Incremental growth of the data structure (no large resizing/rehashing).
+.It
+Optional support for use with shared memory, e.g. memory-mapped file.
+.El
+.Pp
+Delete operations (the key/data destruction) must be synchronized with
+the readers using some reclamation mechanism.
+.\" -
+.Sh FUNCTIONS
+.Bl -tag -width thmap_create
+.It Fn thmap_create
+Construct a new trie-hash map.
+The optional
+.Fa ops
+parameter can
+used to set the custom allocate/free operations (see the description of
+.Vt thmap_ops_t
+below).
+In such case, the
+.Fa baseptr
+is the base (start) address of the address space mapping (it must be
+word-aligned).
+If
+.Fa ops
+is set to
+.Dv NULL ,
+then
+.Xr malloc 3

+should be set to zero.
+Currently, the supported
+.Fa flags
+are:
+.Bl -tag -width THMAP_NOCOPY
+.It Dv THMAP_NOCOPY
+The keys on insert will not be copied and the given pointers to them will
+be expected to be valid and the values constant until the key is deleted;
+by default, the put operation will make a copy of the key.
+.It Dv THMAP_SETROOT

 /*
  * BPF byte-code generation for NPF rules.
+ *
+ * Overview
+ *
+ *	Each NPF rule is compiled into BPF micro-program.  There is a
+ *	BPF byte-code fragment for each higher-level filtering logic,
+ *	e.g. to match L4 protocol, IP/mask, etc.  The generation process
+ *	combines multiple BPF-byte code fragments into one program.
+ *
+ * Basic case
+ *
+ *	Consider a basic case, where all filters should match.  They
+ *	are expressed as logical conjunction, e.g.:
+ *
+ *		A and B and C and D
+ *
+ *	Each test (filter) criterion can be evaluated to true (match) or
+ *	false (no match) and the logic is as follows:
+ *
+ *	- If the value is true, then jump to the "next" test (offset 0).
+ *
+ *	- If the value is false, then jump to the JUMP_MAGIC value (0xff).
+ *	This "magic" value is used to indicate that it will have to be
+ *	patched at a later stage.
+ *
+ *	Once all byte-code fragments are combined into one, then there
+ *	are two additional steps:
+ *
+ *	- Two instructions are appended at the end of the program: return
+ *	"success" followed by return "failure".
+ *
+ *	- All jumps with the JUMP_MAGIC value are patched to point to the
+ *	"return failure" instruction.
+ *
+ *	Therefore, if all filter criteria will match, then the first
+ *	instruction will be reached, indicating a successful match of the
+ *	rule.  Otherwise, if any of the criteria will not match, it will
+ *	take the failure path and the rule will not matching.
+ *
+ * Grouping
+ *
+ *	Filters can have groups, which are have a meaning of logical
+ *	disjunction, e.g.:
+ *
+ *		A and B and (C or D)
+ *
+ *	In such case, the logic inside the group has to be inverted i.e.
+ *	the jump values swapped.  If the test value is true, then jump
+ *	out of the group; if false, then jump "next".  At the end of the
+ *	group, an addition failure path is appended and the JUMP_MAGIC
+ *	uses within the group are patched to jump past the said path.

Added Files:

src/usr.sbin/npf: npf-params.7

Log Message:
NPF improvements:
- Add support for dynamic NETMAP algorithm (stateful net-to-net).
- Add most of the support for the dynamic NAT rules; a little bit more
  userland work is needed to finish this up and enable.
- Replace 'stateful-ends' with more permissive 'stateful-all'.

Well, I did run libnv tests as well as NPF tests and they both passed,
just not on NetBSD. :)  Turns out NetBSD libnv and Github libnv code
bases deviated a little bit, causing a bug in NetBSD (but not upstream).
Anyway, I committed the fix.  As for the NetBSD tests: it takes forever
to recompile and rerun them, so it is not really practical for me.

Thanks for discovering and fixing this.  I think this is the first
serious remote vulnerability in NPF, although limited to IPv6 only.

A minor aspect, but promoting npf_hlen to uint32_t results in wasteful
padding in the struct, so it is better to re-order the struct members
in this case.

If the npc_hlen value is beyond the packet length, NPF's nbuf interface
will catch that, since it performs the bounds check.  However, I think
we should implement some sanity check for the npc_hlen value.  RFC 7112
suggests that the IPv6 header chain should not exceed the MTU size (and
thus fit in the first fragment, in case of fragmentation).  Some value
along these lines could be the basis for a sanity check..

I can just echo this part.  It is completely unrealistic that NetBSD can
maintain its own 802.11 stack these days.  A better approach would be to
sync the code with FreeBSD and treat is as an upstream, trying to merge
the fixes back there.  Not sure if diverging will help syncing the code.

IMO, 802.11n (and there is some FreeBSD code for 802.11ac) is much more
useful feature, as it would allow NetBSD users to use decent WiFI speeds.
Currently supported throughput is pretty miserable for these days..

 Please revert this. You can't make a mechanical change
 (s/kmem_/kmem_intr_/g and so on) to enable lua in softintr
 context. You need to design it.
 
 What if GC kicks-in in softintr? What if the code tries to
 load a chunk of new code in softintr? And there are other
 questions.

I have explained to Lourival that softint context is a very constrained
environment and he should seek for a better design, e.g. have per-CPU
Lua state while keeping such Lua programs mostly stateless and sharing no
global state.  Ideally, we should have deterministic behaviour and memory
pre-allocation with such programs (whether it is Lua or not).

This is tricky with Lua, but I think he understands the implications and
issues.  The change is more of an initial step to (inefficiently) support
the capability.  Meanwhile, those interested can research and experiment
with NPF+Lua.  Such use of Lua is not really meant to be production-ready
at this point.

 Hopefully a vnode lock is needed to access tn_links -- otherwise the
 VOP_LOCK/UNLOCK in tmpfs_reclaim() didn't protect it ...

Yes, tn_links is modified with the vnode lock held.  Unlocked access in
VOP_RECLAIM() racing with the release of the last last reference, used to
cause crashes due to premature reclamation attempts.  Given that VOP_LOCK()
acquires the vnode node, can you explain why this didn't protect it?

 As this commit prevents other threads from obtaining a lock while
 VOP_RECLAIM() is running the protection should be the same as before.

You mean VOP_RECLAIM() is now called with the vnode lock held?  Can you
please add an assert in tmpfs_reclaim() which demonstrates that?

 Is it really a good idea to allocate 528 bytes on the kernel stack?
 File systems nest and already use much stack space.

It is harmless in this case since we get a few or more pages for the stack.

 Looks better to use a pool_cache.

It is worth to create a separate pool_cache(9) only if the allocations can
potentially be very intensive.

 Log Message:
 Fix a race where thread1 runs VOP_REMOVE() and gets preempted in
 tmpfs_reclaim() before the call to tmpfs_free_node().  Thread2
 runs VFS_FHTOVP() and gets a new vnode attached to the node thread1
 is about to destroy.
 
 Change tmpfs_alloc_node() to always assign non-zero generation number
 and tmpfs_inactive() to set the generation number of unlinked nodes
 to zero.

Can you explain how does this help?  It still seems racy to me.
Why not just check for tn_links == 0 in tmpfs_fhtovp()?

 The err vs. errx may be debatable, but since this is usual called via
 other programs the name of the program (and thus the man page to look
 up details) may be usefull.

I mean you have them other way round:

+   len = sizeof(ram);
+   if (sysctlbyname(hw.physmem64, ram, len, NULL, 0))
+   err(EXIT_FAILURE, can't get \hw.physmem64\: %s,

err() already appends the error string for you, while in in ram_fract()
and ram_percent() you want errx().

 I think it was provided so that the macros look the same across different
 ADT's. Don't shoot the messenger, I did not add it. But I will fix the

 The point (as I understand it) is so that if you want to change to another
 ADT where end != NULL (are there any now, that we have banned CIRCLEQ?)
 using the END macro lets you s/FOOQ/BARQ/ and have it mostly work.

Since 1990s (or even earlier) none of the lists in queue(3) had _END(),
apart from the circle queue (for a very obvious reason it makes sense).
Now that CIRCLEQ is banned - you added _END() for LIST and TAILQ.  I do
not follow the logic. :)

I would remove _END() macros to keep the way it always was.  If the goal
is to improve the interface, then now is a good time to design a new API,
but we already have a long thread on tech-userlevel for this..

 There are a number of issues with this. First of all, it pollutes the
 global namespace and can't be used safely from libc the way it is done.

How do you suggest to do it?

 Second, I don't really like adding a special purpose name of a hash
 function which is explicitly not designed to be endian neutral. We
 should provide a fast hash function and be able to change it without
 breaking assumptions, which this is not doing.

Well, the added function is endian-neutral and is generic implementation.
Idea is to provide optimised functions per architecture.  They would
merely override the generic one, but produce the same result regardless
of endianess.  Do you want to do it differently?

 just putting each variant in a separate .c file.  Eg:

 Next opportunity will be with NCQ support, which I hope to look at soon.

 Erm... looking at the file the locking in there looks decidedly dubious.
 
 1) There doesn't seem to be any locking on the hash table.
 2) It isn't clear why the KERNEL_LOCK was acquired in one specific path.
 3) If fileassoc_file_delete() is expected to remove all references for
a vnode, something external must have forced the state of the vnode.
(otherwise the stuff might be added - inc. global init - while this

Yes, locking issues are known in this code (see e.g. PR/35351) and I would
say fileassoc(9) should be disabled by default while this is resolved.

However, I do not really have much interest in fixing fileassoc(9), so my

visible or e.g. PR/45734.

This is cool, thanks!  Can you add an entry to src/doc/CHANGES?  Also,
just wondering - did you try any benchmarks?  I would expect reasonable
improvement.

 IMHO non-atf tests are just as useless as the whole src/regress hierachy
 always was. BUT: finding someone to pick this new tests up and embed them
 in atf should be easy.

They are not useless at all.  Actually, I still use them.

 With this change in place core dumps from ddb (reboot 104) no longer work
 on MP machines.
 
 Before pmap_tlb_shootnow() always returned on the `tp-tp_count == 0'
 check.
 
 Now it goes into the `remote' case and hangs hard trying to reach other
 CPUs.

We could check for panicstr.  Not sure if that is desirable, though.

 Change getnewvnode() to always allocate a fresh vnode and add a helper
 thread (vdrain) to keep the number of allocated vnodes within
 desiredvnodes.
 
 Rename getcleanvnode() to cleanvnode() and let it take a vnode from the
 lists, clean and free it.

Not that I object to the change, but such approach was already discussed in
the past on tech-kern@ and rejected.  See the follow ups of this thread:

http://mail-index.netbsd.org/tech-kern/2009/08/17/msg005861.html

This significantly changes the dynamics of vnode cache and reclamation,
apart from making it single-threaded.  Given the current locking scheme
with its issues (and thus reclamation complexity), the change is probably
good enough for the medium term.  However, in the long term, I would say
that getnewvnode() behaviour should be restored.

 Can you brief on what is the difference between membar_ops(3) and mb(9)?
 

mb(9) predates membar_ops(3).  I do not know why it was left when the
later interface was added.  It seems to me that mb(9) should be removed.
Some good notes from mb(9) man page can be moved to membar_ops(9) though.

  Looks good?
 
 i don't understand what it solves.  can you explain a little?

Here is the updated patch after your changes:

http://www.netbsd.org/~rmind/uvm_anon_freelst2.diff

As you noted, uvm_anfree() can temporarily release the amap lock - that can
happen in amap_copy().  Patch closes the race by moving uvm_anfree() further,
and changes the semantics of the function, now called uvm_anon_freelst(), to
return with amap lock released (plus free anons without lock held).

Thanks for enabling this, however you have ignored points raised on
tech-kern@.  In such case, at least DEBUG and DDB on panic (plus trace
command) should be re-enabled as well.

And, most importantly, this is not communicated to -current users who
will get performance decrease after kernel update.  Apart from updating
motd, I was thinking about some printf()ed warning in the kernel..

 DEBUG is not as usefull as DIAGNOSTIC, and is very verbose.
 My main point is to get KASSERT() back again.
 
 DEBUG and LOCKDEBUG were mentionned, but I don't remmeber a clear

  and DDB on panic (plus trace
  command) should be re-enabled as well.
 
 I also don't think we did reach a consensus about this either.

Well, I object on adding only DIAGNOSTIC, without DEBUG and DDB trace
enabled, as it is counter productive to the idea to gather more info.
LOCKDEBUG would be useful as well, but its very significant effect to
performance can be understood.

Also, it seems that nobody disagreed on enabling DDB trace (as well as
adding DEBUG option).  What makes you think that we did not reach the
consensus?

 With DDB on panic you don't get a core dump, you just see the system
 hang if running X11.
 With trace (assuming you're not running X11), you have the usefull panic
 message scroll away on a standard VGA screen.

Again, call ddb_vgapost was proposed.  You can still coredump, either
manually or just by adding another command.  Also, if automatic coredump
fails (to me it is often the case) - then info is left uncollected.
