manu | Fix PUFFS node use-after-reclaim
When puffs_cookie2vnode() misses an entry, vcache_get()
creates a new node (puffs_vfsop_loadvnode being called to
initialize the PUFFS part), then it discovers it is VNON,
and tries to vrele() it. vrele() calls VOP_INACTIVE(),
which led us in puffs_vnop_inactive() where we sent a
request to the filesystem for a node that already had been
reclaimed.
The fix is to check for VNON nodes in puffs_vnop_inactive()
and to return without doing anyting. This is suboptimal, but
a better workaround would probably need to modify vcache API,
with an impact on other filesystems. Let us keep it simple.

hannken | Fix the puffs_sop_thread -> puffs_cookie2vnode path:
- pass the cookie by reference
- add missing mutex_exit()
- update assertion for VNON typed vnodes

otherwise the updated ctime/mtime appears after the cached entry expire.

- field "pa_nhashbuckets" of struct "puffs_kargs" becomes a no-op.
and should be removed on the next protocol version bump.

dholland | Excise struct componentname from the namecache.
This uglifies the interface, because several operations need to be
passed the namei flags and cache_lookup also needs for the time being
to be passed cnp->cn_nameiop. Nonetheless, it's a net benefit.
The glop should be able to go away eventually but requires structural
cleanup elsewhere first.
This change requires a kernel bump.

manu | Add name and atttribute cache with filesytem provided TTL.
lookup, create, mknod, mkdir, symlink, getattr and setattr messages
have been extended so that attributes and their TTL can be provided
by the filesytem. lookup, create, mknod, mkdir, and symlink messages
are also extended so that the filesystem can provide name TTL.

manu | Make sure pagedaemon does not sleep for memory in puffs_vnop_sleep.
Add KASSERT on any sleeping memory allocation to check it cannot happen again.
|
| 1.20 |
| 29-Aug-2011 |
manu | Add a mutex for operations that touch size (setattr, getattr, write, fsync).
This is required to avoid data corruption bugs, where a getattr slices
itself within a setattr operation, and sets the size to the stall value
it got from the filesystem. That value is smaller than the one set by
setattr, and the call to uvm_vnp_setsize() trigged a spurious truncate.
The result is a chunk of zeroed data in the file.
Such a situation can easily happen when the ioflush thread issue a
VOP_FSYNC/puffs_vnop_sync/flushvncache/dosetattrn while andother process
do a sys_stat/VOP_GETATTR/puffs_vnop_getattr.
This mutex on size operation can be removed the day we decide VOP_GETATTR
has to operated on a locked vnode, since the other operations that touch
size already require that.

rmind | Welcome to 5.99.53! Merge rmind-uvmplock branch:
- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.
- Simplify locking in some pmap(9) modules by removing P->V locking.
- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).
- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.
- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.
Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.

pooka | * fix a race i introduced almost two years ago in rev 1.116:
operations creating a node cannot be considered outgoing operations,
since after return from userspace they modify file system state
by creating a new node. if we do not protect the file system by
holding the directory lock, a lookup operation might race us into
the kernel and create the node earlier.
* remove pnode from hashlish before sending the reclaim faf off to
userspace. also, hold pmp_lock while frobbing the list.

Welcome to 4.99.55:
- Add a lot of missing selinit() and seldestroy() calls.
- Merge selwakeup() and selnotify() calls into a single selnotify().
- Add an additional 'events' argument to selnotify() call. It will
indicate which event (POLL_IN, POLL_OUT, etc) happen. If unknown,
zero may be used.
Note: please pass appropriate value of 'events' where possible.

ad | specfs changes for PR kern/37717 (raidclose() is no longer called on
shutdown). There are still problems with device access and a PR will be
filed.
- Kill checkalias(). Allow multiple vnodes to reference a single device.
- Don't play dangerous tricks with block vnodes to ensure that only one
vnode can describe a block device. Instead, prohibit concurrent opens of
block devices. As a bonus remove the unreliable code that prevents
multiple file system mounts on the same device. It's no longer needed.
- Track opens by vnode and by device. Issue cdev_close() when the last open
goes away, instead of abusing vnode::v_usecount to tell if the device is
open.

pooka | Restructure the messaging interface a bit more: make all interfacing
with the file server happen through puffs_msg_enqueue() and
puffs_msg_wait() instead of having a billion different routines.
Build the existing system upon these two. Most importantly though,
decouple insertation into the op queue from the actual wait. This
is useful for a number of reasons coming soon to a cvs repo near you.

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)

If kernel resource allocation fails after the file server has
committed something, issue an abort. The abort is done through
the regular op channel, e.g. failed mkdir leads to regular rmdir,
inactive and reclaim. No internal interface is planned currently
for the one file system out of a million which would implement it
to benefit from the one case in a billion where kernel resource
allocation actually does fail and out of that one case in a trillion
where internal vs. external would make a difference.

Make sure ioflush does not sleep in PUFFS code path, waiting for a mutex,
a memory allocation, or a response from the filesystem.
This avoids deadlocks in the following situations:
1) when memory is low: ioflush waits the fileystem, the fielsystem waits
for memory
2) when the filesystem does not respond (e.g.: network outage ona
distributed filesystem)
Fix the build that was broken by struct lwp *updateproc reference in
RUMP-visible code. Instead of checking that updateproc (aka ioflush,
aka syncer) will not sleep in PUFFS code, I check for any kernel thread:
after all none of them are designed to hang awaiting for a remote filesystem
operation to complete.
Roll back the change that forced kernel threads to not sleep in PUFFS.
The change does not make consensus, since only pagedaemon should need it.
Other threads will tolerate sleeping, and problems here are only symptoms
that something is going wrong in memory management. The cause, not the
symptoms, need to be fixed.
Make sure pagedaemon does not sleep for memory in puffs_vnop_sleep.
Add KASSERT on any sleeping memory allocation to check it cannot happen again.
Remove #ifdef DIAGNOSTIC guards around KASSERT, as the macro contains them

Add a mutex for operations that touch size (setattr, getattr, write, fsync).
This is required to avoid data corruption bugs, where a getattr slices
itself within a setattr operation, and sets the size to the stall value
it got from the filesystem. That value is smaller than the one set by
setattr, and the call to uvm_vnp_setsize() trigged a spurious truncate.
The result is a chunk of zeroed data in the file.
Such a situation can easily happen when the ioflush thread issue a
VOP_FSYNC/puffs_vnop_sync/flushvncache/dosetattrn while andother process
do a sys_stat/VOP_GETATTR/puffs_vnop_getattr.
This mutex on size operation can be removed the day we decide VOP_GETATTR
has to operated on a locked vnode, since the other operations that touch
size already require that.

Use C89 function definition
Add name and atttribute cache with filesytem provided TTL.
lookup, create, mknod, mkdir, symlink, getattr and setattr messages
have been extended so that attributes and their TTL can be provided
by the filesytem. lookup, create, mknod, mkdir, and symlink messages
are also extended so that the filesystem can provide name TTL.
Add PUFFS_KFLAG_CACHE_FS_TTL flag to puffs_init(3) to use name and
attribute cache with filesystem provided TTL.
lookup, create, mknod, mkdir, symlink, getattr and setattr messages
have been extended so that attributes and their TTL can be provided
by the filesytem. lookup, create, mknod, mkdir, and symlink messages
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 "and".
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

sys/fs/puffs/puffs_vnops.c: revision 1.197
sys/fs/puffs/puffs_node.c: revision 1.35
Fix PUFFS node use-after-reclaim
When puffs_cookie2vnode() misses an entry, vcache_get()
creates a new node (puffs_vfsop_loadvnode being called to
initialize the PUFFS part), then it discovers it is VNON,
and tries to vrele() it. vrele() calls VOP_INACTIVE(),
which led us in puffs_vnop_inactive() where we sent a
request to the filesystem for a node that already had been
reclaimed.
The fix is to check for VNON nodes in puffs_vnop_inactive()
and to return without doing anyting. This is suboptimal, but
a better workaround would probably need to modify vcache API,
with an impact on other filesystems. Let us keep it simple.

Change puffs from hashlist to vcache.
- field "pa_nhashbuckets" of struct "puffs_kargs" becomes a no-op.
and should be removed on the next protocol version bump.
