Allow calling puffs_mount(3) before puffs_daemon(3)

puffs_daemon(3) creates a pipe before forking, and the parent process
waits for the child to either complete puffs_mount(3) or fail. If a
user calls puffs_daemon(3) after puffs_mount(3), the function
deadlocks. While this error-reporting functionality is really a nice
thing to have, deadlocking is not great. If the filesystem has already
been mounted, puffs_mount(3) should just daemonize the process and
return.

This became an issue because fuse_daemonize(3) in FUSE API had no such
requirement and some FUSE filesystems in the wild suffered deadlocks.

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.

Add PUFFS_KFLAG_NOFLUSH_META to prevent sending metadata flush to FUSE
FUSE filesystems do not expect to get metadata updates for [amc]time
and size, they updates the value on their own after operations.

The PUFFS PUFFS_KFLAG_NOFLUSH_META option prevents regular metadata cache
flushes to the filesystem , and libperfuse uses it to match Linux FUSE
behavior.

While there, fix a bug in SETATTR: do not update kernel metadata cache
from SETATTR reply when the request is asynchronous, as we do not have
the reply yet.

Update file size after write without metadata flush
If we do not use metadata flush, we must make sure the size is updated
in the filesystem after a write, otherwise the next GETATTR will get us
a stale value and the file will be truncated.

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.

have been extended so that attributes and their TTL can be provided
by the filesytem. lookup, create, mknod, mkdir, and symlink messages

Add PUFFS_KFLAG_CACHE_FS_TTL flag to puffs_init(3) to use name and

have been extended so that attributes and their TTL can be provided

are also extended so that the filesystem can provide name TTL.
The filesystem updates attributes and TTL using
puffs_pn_getvap(3), puffs_pn_getvattl(3), and puffs_pn_getcnttl(3)
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;.

- 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

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.

Introduce puffs_daemon(), which works like daemon(3) except that it

parent process until the file system has been mounted.  This makes

Pull the daemonizing code out of the library mainloop into the file

Step 3 and currently final step of a more general purpose event loop:
support removal and addition of i/o file descriptors on the fly.

* detect closed file descriptors
* automatically free waiters of a dead file descriptor
* give the file server the possibility to specify a callback which
  notifies of a dead file descriptor
* move loop function to be a property of the mainloop instead of
  framebuf (doesn't change effective behaviour)
* add the possibility to configure a timespec parameter which
  attempts to call the loop function periodically
* move the event loop functions from the puffs_framebuf namespace
  to puffs_framev to differential between pure memory management
  functions
