Use size_t in place of voff_t in puffs_setrootinfo(3)

Chuck Silvers pointed out that voff_t was also supposed to be
kernel-only. The correct type to use in userland would be off_t, but
since changing vsize_t to either voff_t or off_t is an ABI change on
32-bit platforms, we use size_t knowing that it is technically
incorrect.

Avoid using register_t or vsize_t in <puffs.h>

<puffs.h> is a user-space header, and should not use any of
kernel-only types. It's not reasonable to require user-land
filesystems to #define _KERNTYPES.

Fix regression that has been introduced when the lookup/reclaim race
condition was addressed in libpuffs by counting lookups.
The fix assumes that cookies map to struct puffs_cookie, which has not
been documented as a requirement for filesystems using libpuffs. As an
example, we got burnt by this assumption in libp2k (kern/46734), and
we fixed bit by actually mapping libp2k cookies to struct puffs_node.
It is unlikely, but there may be third party filesystems that use cookies
unmapped to struct puffs_node, and they were left broken for now.
- we introduce a puffs_init() flag PUFFS_FLAG_PNCOOKIE that let filesystems
inform libpuffs that they map cookies to struct puffs_node. Is that flag
is used, the lookup/reclaim race condition fix is enabled. We enable the
flag for libp2k.
- filesystems that use puffs_pn_new() obviouslty use struct puffs_node
and gain PUFFS_FLAG_PNCOOKIE automatically even if they did not specify
it in puffs_init(). This include all our PUFFS filesystem in-tree except
libp2k.
- for filesystems not willing to use struct puffs_node, we introduce a
reclaim2 vnop, which is reclaim with an additionnal lookup count argument.
This vnop let the filesystem implement the lookup/reclaim race fix on
its own.

- Fix same vnodes associated with multiple cookies
The scheme used to retreive known nodes on lookup was flawed, as it only
used parent and name. This produced a different cookie for the same file
if it was renamed, when looking up ../ or when dealing with multiple files
associated with the same name through link(2).
We therefore abandon the use of node name and introduce hashed lists of
inodes. This causes a huge rewrite of reclaim code, which do not attempt
to keep parents allocated until all their children are reclaimed
- Fix race conditions in reclaim
There are a few situations where we issue multiple FUSE operations for
a PUFFS operation. On reclaim, we therefore have to wait for all FUSE
operation to complete, not just the current exchanges. We do this by
introducing node reference count with node_ref() and node_rele().
- Detect data loss caused by FAF
VOP_PUTPAGES causes FAF writes where the kernel does not check the
operation result. At least issue a warning on error.
- Enjoy FAF shortcut on setattr
No need to wait for the result if the kernel does not want it. There is
however an exception for setattr that touch the size, we need to wait
for completion because we have other operations queued for after the
resize.
- Fix fchmod() on write-open file
fchmod() on a node open with write privilege will send setattr with both mode
and size set. This confuses some FUSE filesystem. Therefore we send two FUSE
operations, one for mode, and one for size.
- Remove node TTL handling for netbsd-5 for simplicity sake. The code
still builds on netbsd-5 but does not have the node TTL feature anymore.
It works fine with kernel support on netbsd-6.
- Improve PUFFS_KFLAG_CACHE_FS_TTL by reclaiming older inactive nodes.
The normal kernel behavior is to retain inactive nodes in the freelist
until it runs out of vnodes. This has some merit for local filesystems,
where the cost of an allocation is about the same as the cost of a
lookup. But that situation is not true for distributed filesystems.
On the other hand, keeping inactive nodes for a long time hold memory
in the file server process, and when the kernel runs out of vnodes, it
produce reclaim avalanches that increase lattency for other operations.
We do not reclaim inactive vnodes immediatly either, as they may be
looked up again shortly. Instead we introduce a grace time and we
reclaim nodes that have been inactive beyond the grace time.
- Fix lookup/reclaim race condition.
The above improvement undercovered a race condition between lookup and
reclaim. If we reclaimed a vnode associated with a userland cookie while
a lookup returning that same cookiewas inprogress, then the kernel ends
up with a vnode associated with a cookie that has been reclaimed in
userland. Next operation on the cookie will crash (or at least confuse)
the filesystem.
We fix this by introducing a lookup count in kernel and userland. On
reclaim, the kernel sends the count, which enable userland to detect
situation where it initiated a lookup that is not completed in kernel.
In such a situation, the reclaim must be ignored, as the node is about
to be looked up again.
Fix hang unmount bug introduced by last commit.
We introduced a slow queue for delayed reclaims, while the existing
queue for unmount, flush and exist has been renamed fast queue. Both
queues had timestamp for when an operation should be done, but it was
useless for the fast queue, which is always used to run an operation
ASAP. And the timestamp test had an error that turned ASAP into "at next
tick", but nobody what there to wake the thread at next tick, hence
the hang. The fix is to remove the useless and buggy timestamp test for
fast queue.
Rename slow sopreq queue into node sopreq queue, to refet the fact that
is only intended for postponed node reclaims.
When purging the node sopreq queue, do not call puffs_msg_sendresp(), as
it makes no sense.
Fix race condition between (create|mknod|mkdir|symlino) and reclaim, just
like we did it between lookup and reclaim.
Missing bit in previous commit (prevent race between create|mknod|mkdir|symlink
and reclaim)
Bump date for previous.
New sentence, new line; remove trailing whitespace; fix typos;
punctuation nits.
Add PUFFS_KFLAG_CACHE_DOTDOT so that vnodes hold a reference on their
parent, keeping them active, and allowing to lookup .. without sending
a request to the filesystem.
Enable the featuure for perfused, as this is how FUSE works.
Missing bit in previous commit (PUFFS_KFLAG_CACHE_DOTDOT option to avoid
looking up ..)

Use new PUFFS_KFLAG_CACHE_FS_TTL option to puffs_init(3) so that
FUSE TTL on name and attributes are used. This save many PUFFS
operations and improves performances.
PUFFS_KFLAG_CACHE_FS_TTL is #ifdef'ed in many places for now so that
libperfuse can still be used on netbsd-5.
Split file system.
Comma fixes.
Remove dangling &quot;and&quot;.
Bump date for previous.
- Makesure update_va does not change vnode size when it should not. For
instance when doing a fault-issued VOP_GETPAGES within VOP_WRITE, changing
size leads to panic: genfs_getpages: past eof.
-Handle ticks wrap around for vnode name andattribute timeout
- When using PUFFS_KFLAG_CACHE_FS_TTL, do not use puffs_node to carry
  attribute and TTL fora newly created node. Instead extend puffs_newinfo
  and add puffs_newinfo_setva() and puffs_newinfo_setttl()
- Remove node_mk_common_final in libperfuse. It used to set uid/gid for
  a newly created vnode but has been made redundant along time ago since
  uid and gid are properly set in FUSE header.
- In libperfuse, check for corner case where opc = 0 on INACTIVE and   RECLAIM
(how is it possible? Check for it to avoid a crash anyway)
- In libperfuse, make sure we unlimit RLIMIT_AS and RLIMIT_DATA so that
  we do notrun out of memory because the kernel is lazy at reclaiming vnodes.
- In libperfuse, cleanup style of perfuse_destroy_pn()
Do not set PUFFS_KFLAG_CACHE_FS_TTL for PUFFS tests

* support extended attributes
* bump major due to structure growth
* add some spare space
* remove ABI sillyness
Support extended attributes.
Fix multiple non compliances in our Linux-like extattr API, and make it
public so that it can be used.
Improve a bit listxattr(2). It attemps to list both system and user
extended attributes, and it faled if calling user did not have privilege
for reading system EA. Now we just lise user EA and skip system EA in
reading them is not allowed.
Fix bug introduced in previous commuit: Do not vrele() a vnode we did not
obtained.
Improve UFS1 extended attributes usability
- autocreate attribute backing file for new attributes
- autoload attributes when issuing extattrctl start
- when autoloading attributes, do not display garbage warning when looking
up entries that got ENOENT
Add a flag to VOP_LISTEXTATTR(9) so that the vnode interface can tell the
filesystem in which format extended attribute shall be listed.
There are currently two formats:
- NUL-terminated strings, used for listxattr(2), this is the default.
- one byte length-pprefixed, non NUL-terminated strings, used for
  extattr_list_file(2), which is obtanined by setting the
  EXTATTR_LIST_PREFIXLEN flag to VOP_LISTEXTATTR(9)
This approach avoid the need for converting the list back and forth, except
in libperfuse, since FUSE uses NUL-terminated strings, and the kernel may
have requested EXTATTR_LIST_PREFIXLEN.

This makes the size the same on 64bit archs.  Don't bother bumping
any version, since you'd have explicitly had to jump through some
hoops to use pathconf before.

Implement lazy contexts for file systems using puffs_mainloop().
Previously each request was executed on its own callcontext and
switched to every time the request was being processed.  Now requests
borrow the mainloop context and switch only if/when they yield.
This takes two context switches away from a file system request
bringing down the typical amounts 2->0 (e.g. dtfs) and 4->2 (e.g.
psshfs).

The interfaces for manually executing requests changed a bit:
puffs_dispatch_create() and puffs_dispatch_exec() must now be used.
They are not tested, as nothing in-tree wants them and I doubt
anyone else is really interested in them either.

Also do some misc code cleanup related to execution contexts.  The
"work-in-progress checkpoint" committed over a year ago was starting
to look slightly weed-infested.

Part 3/n of extensive changes to message handling:

Get rid of the original puffs_req(3) framework and use puffs_framebuf(3)
instead for file system requests.  It has the advantage of being
suitable for transporting a distributed message passing protocol
and therefore us being able to run the file system server on any
host.

Ok, puffs is not quite here yet: libpuffs needs to grow request
routing support and the message contents need to be munged into a
host independent format.  Saying which format would be telling,
but it might begin with an X, end in an L and have the 13th character
in the middle.  Keep an eye out for the sequels: Parts 3+m/n.

Rototill.

Ok, ok, a few more words about it: stop holding puffs_cc as a holy
value and passing it around to almost every possible place (popquiz:
which kernel variable does this remind you of?).  Instead, pass
the natural choice, puffs_usermount, and fetch puffs_cc via
puffs_cc_getcc() only in routines which actually need it.  This
not only simplifies code, but (thanks to the introduction of
puffs_cc_getcc()) enables constructs which weren't previously sanely
possible, say layering as a curious example.

There's still a little to do on this front, but this was the major
fs interface blast.

Part 1/n of some pretty extensive changes to how the kernel module
interacts with the userspace file server:

  * since the kernel-user communication is not purely request-response
    anymore (hasn't been since 2006), try to rename some "request" to
    "message".  more similar mangling will take place in the future.

  * completely rework how messages are allocated.  previously most of
    them were borrowed from the stack (originally *all* of them),
    but now always allocate dynamically.  this makes the structure
    of the code much cleaner.  also makes it possible to fix a
    locking order violation.  it enables plenty of future enhancements.

  * start generalizing the transport interface to be independent of puffs

  * move transport interface to read/write instead of ioctl.  the
    old one had legacy design problems, and besides, ioctl's suck.
    implement a very generic version for now; this will be
    worked on later hopefully some day reaching "highly optimized".

  * implement libpuffs support behind existing library request
    interfaces.  this will change eventually (I hate those interfaces)

Add puffs "frame buffers", which are an abstraction of the buffering
and event handling mechanisms required in file servers with blocking
I/O backends.  puffs_framebuf is built on the concept of puffs_cc
and uses those to multiplex execution where needed.

File systems are required to implement three methods:
  * read frame
  * write frame
  * compare if frame is a response to the given one

Memory management is provided by puffs_framebuf, but the file
systems must still, of course, interpret the protocol and do e.g.
byte order conversion.

As always, puffs_framebuf is work in progress.  Current users are
mount_psshfs and mount_9p.

Instead of keeping on adding parameters to puffs_mount(), make it
only take the bare essentials, which currently means removing
"maxreqlen" from the argument list (all current callers I'm aware
of set it as 0 anyway).  Introduce puffs_init(), which provides a
context for setting various parameters and puffs_domount(), which
can be used to mount the file system.  Keep puffs_mount() as a
shortcut for the above two for simple file systems.

add libpuffs - the userspace programming interface for puffs

This work was initially started and completed for Google SoC 2005
and tweaked to work a bit better in the past few weeks.  While
being far from complete, it is functional enough to be able and
stable to host a fairly general-purpose in-memory file system in
userspace.  Even so, puffs should be considered experimental and
no binary compatibility for interfaces or crash-freedom or zero
security implications should be relied upon just yet.

The GSoC project was mentored by William Studenmund and the final
review for the code was done by Christos.
