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.

Implement sharing of vnode_t::v_interlock amongst vnodes:
- Lock is shared amongst UVM objects using uvm_obj_setlock() or getnewvnode().
- Adjust vnode cache to handle unsharing, add VI_LOCKSHARE flag for that.
- Use sharing in tmpfs and layerfs for underlying object.
- Simplify locking in ubc_fault().
- Sprinkle some asserts.

Discussed with ad@.

PR/40936: Frederik Sausmikat: ext2fs: add support for inodes > 128 bytes
Support variable inode sizes.
catch up with variable inode size.
Don't use e2fs_inode_size in superblock on E2FS_REV0 file system.
- accept only EXT2_REV0_DINODE_SIZE inodesize on -O 0
- use inodesize to get offset of inode, not struct ext2fs_dinode array
Replace a magic number with a new EXT2_REV0_DINODE_SIZE macro.
Use EXT2_DINODE_SIZE() to get offset of inode, not struct ext2fs_dinode array.
Fix botched logic in inodesize check.
Use inodesize to get offset of inode in one more place.
- add a sanity check for e2fs_inode_size in readsb()
- use EXT2_DINODE_SIZE() rather than sizeof(struct ext2fs_dinode) or
  struct ext2fs_dinode array/pointer to see e2fs_ipb and inode offsets
Sort options.
New sentence, new line.
Sort options in usage.
- unsigned -> unsigned int
- remove unnecessary casts from malloc(3) and free(3)
- fix a bogus indent
Use "size > INT32_MAX" rather than "size >= 0x80000000U" to check 2GB limit.
Add missed byteswap ops against ext2fs_dinode members.
Handle 32 bit uid field on E2FS_REV1.

The VATTR_NULL/VREF/VHOLD/HOLDRELE() macros lost their will to live
years ago when the kernel was modified to not alter ABI based on
DIAGNOSTIC, and now just call the respective function interfaces
(in lowercase).  Plenty of mix'n match upper/lowercase has creeped
into the tree since then.  Nuke the macros and convert all callsites
to lowercase.

Proposed with no objections on tech-kern@:

The vnode is always expected to be locked, so no locking is done outside

Make sure all cached buffers with valid, not yet written data have been
run through copy-on-write.  Call fscow_run() with valid data where possible.

The LP_UFSCOW hack is no longer needed to protect ffs_copyonwrite() against
endless recursion.

- Add a flag B_MODIFY to bread(), breada() and breadn().  If set the caller
  intends to modify the buffer returned.

- Always run copy-on-write on buffers returned from ffs_balloc().

- Add new function ffs_getblk() that gets a buffer, assigns a new blkno,
  may clear the buffer and runs copy-on-write.  Process possible errors
  from getblk() or fscow_run().  Part of PR kern/38664.

PR kern/38141 lookup/vfs_busy acquire rwlock recursively

Simplify the mount locking. Remove all the crud to deal with recursion on
the mount lock, and crud to deal with unmount as another weirdo lock.

Hopefully this will once and for all fix the deadlocks with this. With this
commit there are two locks on each mount:

- krwlock_t mnt_unmounting. This is used to prevent unmount across critical
  sections like getnewvnode(). It's only ever read locked with rw_tryenter(),
  and is only ever write locked in dounmount(). A write hold can't be taken
  on this lock if the current LWP could hold a vnode lock.

- kmutex_t mnt_updating. This is taken by threads updating the mount, for
  example when going r/o -> r/w, and is only present to serialize updates.
  In order to take this lock, a read hold must first be taken on
  mnt_unmounting, and the two need to be held across the operation.

One effect of this change: previously if an unmount failed, we would make a
half hearted attempt to back out of it gracefully, but that was unlikely to
work in a lot of cases. Now while an unmount that will be aborted is in
progress, new file operations within the mount will fail instead of being
delayed. That is unlikely to be a problem though, because if the admin
requests unmount of a file system then s(he) has made a decision to deny
access to the resource.

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.

Remove the "struct lwp *" argument from all VFS and VOP interfaces.
The general trend is to remove it from all kernel interfaces and

Change the VFS_MOUNT() interface so that the 'data' buffer passed to the
fs code is a kernel buffer, pass though the length of the buffer as well.
Since the length of the userspace buffer isn'it (yet) passed through the mount
system call, add a field to the vfsops structure containing the default length.
Split sys_mount() for calls from compat code.
Ride one of the recent kernel version changes - old fs LKMs will load, but
sys_mount() will reject any attempt to use them.

Using POOL_INIT here makes no sense, since file systems always have

init in the init method.  Give malloc types the same treatment.
Makes file systems nicer to work with in linksetless environments
and fixes a few LKM discrepancies.

New file system suspension API to replace vn_start_write and vn_finished_write.
The suspension helpers are now put into file system specific operations.
This means every file system not supporting these helpers cannot be suspended
and therefore snapshots are no longer possible.

Implemented for file systems of type ffs.

The new API is enabled on a kernel option NEWVNGATE.  This option is
not enabled by default in any kernel config.

Presented and discussed on tech-kern with much input from
Bill Studenmund <wrstuden@netbsd.org> and YAMAMOTO Takashi <yamt@netbsd.org>.

Welcome to 4.99.9 (new vfs op vfs_suspendctl).

Replace the LIST structure mp->mnt_vnodelist to a TAILQ structure since all
vnodes were synced and processed backwards. This meant that the last
accessed node was processed first and the earlierst last.

An extra benefit is the removal of the ugly hack from the Berkly days on
LFS.

In the proces, i've also replaced the various variations hand written loops
by the TAILQ_FOREACH() macro's.

Apply the NFS exports list rototill patch:

- Remove all NFS related stuff from file system specific code.
- Drop the vfs_checkexp hook and generalize it in the new nfs_check_export
  function, thus removing redundancy from all file systems.
- Move all NFS export-related stuff from kern/vfs_subr.c to the new
  file sys/nfs/nfs_export.c.  The former was becoming large and its code
  is always compiled, regardless of the build options.  Using the latter,
  the code is only compiled in when NFSSERVER is enabled.  While doing this,
  also make some functions in nfs_subs.c conditional to NFSSERVER.
- Add a new command in nfssvc(2), called NFSSVC_SETEXPORTSLIST, that takes a
  path and a set of export entries.  At the moment it can only clear the
  exports list or append entries, one by one, but it is done in a way that
  allows setting the whole set of entries atomically in the future (see the
  comment in mountd_set_exports_list or in doc/TODO).
- Change mountd(8) to use the nfssvc(2) system call instead of mount(2) so
  that it becomes file system agnostic.  In fact, all this whole thing was
  done to remove a 'XXX' block from this utility!
- Change the mount*, newfs and fsck* userland utilities to not deal with NFS
  exports initialization; done internally by the kernel when initializing
  the NFS support for each file system.
- Implement an interface for VFS (called VFS hooks) so that several kernel
  subsystems can run arbitrary code upon receipt of specific VFS events.
  At the moment, this only provides support for unmount and is used to
  destroy NFS exports lists from the file systems being unmounted, though it
  has room for extension.

Thanks go to yamt@, chs@, thorpej@, wrstuden@ and others for their comments
and advice in the development of this patch.

Add support for large files (>2GB).
Like Linux, automagically convert old filesystem to use this,
if they are already at revision 1.
For revision 0, just punt (unlike Linux; makes me a bit too nervous.)

There should be an option to fsck_ext2fs to upgrade revision 0 to revision 1.

Add a new VNODE_LOCKDEBUG option, which enables checks in the VOP_*()
calls to ensure that the vnode lock state is as expected when the VOP
call is made.  Modify vnode_if.src to set the expected state according
to the documenting lock table for each VOP.  Modify vnode_if.sh to emit
the checks.

Notes:
- The checks are only performed if the vnode has the VLOCKSWORK bit
  set.  Some file systems (e.g. specfs) don't even bother with vnode
  locks, so of course the checks will fail.
- We can't actually run with VNODE_LOCKDEBUG because there are so many
  vnode locking problems, not the least of which is the "use SHARED for
  VOP_READ()" issue, which screws things up for the entire call chain.

Inspired by similar changes in OpenBSD, but implemented differently.

Fixing age old cruft:
* Rather than using mnt_maxsymlinklen to indicate that a file systems returns
  d_type fields(!), add a new internal flag, IMNT_DTYPE.

Add 3 new elements to ufsmount:
* um_maxsymlinklen, replaces mnt_maxsymlinklen (which never should have existed
  in the first place).
* um_dirblksiz, which tracks the current directory block size, eliminating the
  FS-specific checks littered throughout the code.  This may be used later to
  make the block size variable.
* um_maxfilesize, which is the maximum file size, possibly adjusted lower due
  to implementation issues.

Add a new flag, IN_MODIFY.  This is like IN_UPDATE|IN_CHANGE, but unlike
setting those flags, it does not cause the inode to be written in the periodic
sync.  This is used for writes to special files (devices and named pipes) and
FIFOs.

Do not preemptively sync updates to access times and modification times.  They
are now updated in the inode only opportunistically, or when the file or device
is closed.  (Really, it should be delayed beyond close, but this is enough to
help substantially with device nodes.)

And the most amusing part:
Trickle sync was broken on both FFS and ext2fs, in different ways.  In FFS, the
periodic call to VFS_SYNC(MNT_LAZY) was still causing all file data to be
synced.  In ext2fs, it was causing the metadata to *not* be synced.  We now
only call VOP_UPDATE() on the node if we're doing MNT_LAZY.  I've confirmed
that we do in fact trickle correctly now.

Add ffs internal snapshots. Written by Marshall Kirk McKusick for FreeBSD.

- Not enabled by default. Needs kernel option FFS_SNAPSHOT.
- Change parameters of ffs_blkfree.
- Let the copy-on-write functions return an error so spec_strategy
    may fail if the copy-on-write fails.
- Change genfs_*lock*() to use vp->v_vnlock instead of &vp->v_lock.
- Add flag B_METAONLY to VOP_BALLOC to return indirect block buffer.
- Add a function ffs_checkfreefile needed for snapshot creation.
- Add special handling of snapshot files:
    Snapshots may not be opened for writing and the attributes are read-only.
    Use the mtime as the time this snapshot was taken.
    Deny mtime updates for snapshot files.
- Add function transferlockers to transfer any waiting processes from
  one lock to another.
- Add vfsop VFS_SNAPSHOT to take a snapshot and make it accessible through
  a vnode.
- Add snapshot support to ls, fsck_ffs and dump.

This adds pools to the list of things that lkms must do manually

lkms are second class citizens.  Of a sort.

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.

- While was there, fixed a bug in ext2fs, locking problems with vfs_getfsstat(),
  and factored out some of the vfsop statfs() code to copy_statfs_info(). This
  fixes the problem where some filesystems forgot to set fsid.

- All device switches is defined as a constant structure in device drivers.

- The new grammer ``device-major'' is introduced to ``files''.

	device-major <prefix> char <num> [block <num>] [<rules>]

- All device major numbers must be listed up in port dependent majors.<arch>
  by using this grammer.

- Added the new naming convention.
  The name of the device switch must be <prefix>_[bc]devsw for auto-generation
  of device switch tables.

- The backward compatibility of loading block/character device
  switch by LKM framework is broken. This is necessary to convert
  from block/character device major to device name in runtime and vice versa.

- The restriction to assign device major by LKM is completely removed.
  We don't need to reserve LKM entries for dynamic loading of device switch.

- In compile time, device major numbers list is packed into the kernel and
  the LKM framework will refer it to assign device major number dynamically.

Curproc->curlwp renaming.

Change uses of "curproc->l_proc" back to "curproc", which is more like the
original use. Bare uses of "curproc" are now "curlwp".

"curproc" is now #defined in proc.h as ((curlwp) ? (curlwp)->l_proc) : NULL)
so that it is always safe to reference curproc (*de*referencing curproc
is another story, but that's always been true).

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.

* rename REVOKEALL to REVOKEALIAS, and add a REVOKECLONE flag, to pass

* the revoke system call will revoke all aliases, as before, but not the

  clone vnode (access and getattr)
* add a copy of the vnode vattr structure of the original 'master' vnode
  to the specinfo of a cloned vnode. could possibly redirect getattr to
  the 'master' vnode, but this has issues with revoke
* add a vdev_reassignvp function that disassociates a vnode from its
  original device, and reassociates it with the specified dev_t. to be
  used by cloning devices only, in case a new minor is allocated.
* change all direct references in drivers to v_devcookie and v_rdev
  to vdev_privdata(vp) and vdev_rdev(vp). for diagnostic purposes
  when debugging race conditions that still exist wrt. locking and
  revoking vnodes.

Various changes to make cloning devices possible:

	* Add an extra argument (struct vnode **) to VOP_OPEN. If it is
	  not NULL, specfs will create a cloned (aliased) vnode during
	  the call, and return it there. The caller should release and
	  unlock the original vnode if a new vnode was returned. The
	  new vnode is returned locked.

	* Add a flag field to the cdevsw and bdevsw structures.
	  DF_CLONING indicates that it wants a new vnode for each
	  open (XXX is there a better way? devprop?)

	* If a device is cloning, always call the close entry
	  point for a VOP_CLOSE.


Also, rewrite cons.c to do the right thing with vnodes. Use VOPs
rather then direct device entry calls. Suggested by mycroft@

Light to moderate testing done an i386 system (arch doesn't matter
though, these are MI changes).

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.

add a new VFS op, vfs_reinit, which is called when desiredvnodes is
adjusted via sysctl.  file systems that have hash tables which are
sized based on the value of this variable now resize those hash tables
using the new value.  the max number of FFS softdeps is also recalculated.

convert various file systems to use the <sys/queue.h> macros for
their hash tables.

Add new VFS op routine - vfs_done and call it on filesystem detach
in vfs_detach(). vfs_done may free global filesystem's resources,
typically those allocated in respective filesystem's init function.
Needed so those filesystems which went in via LKM have a chance to
clean after themselves before unloading. This fixes random panics
when LKM for filesystem using pools was loaded and unloaded several
times.

For each leaf filesystem, add appropriate vfs_done routine.

Initial commit of recent changes to make DEV_BSIZE go away.

Runs on i386, needs work on other arch's. Main kernel routines should be
fine, but a number of the stand programs need help.

cd, fd, ccd, wd, and sd have been updated. sd has been tested with non-512
byte block devices. vnd, raidframe, and lfs need work.

Non 2**n block support is automatic for LKM's and conditional for kernels
on "options NON_PO2_BLOCKS".

pull up rev 1.28 from trunk (requested by wrstuden):
  In spec_close(), call the device's close routine with the vnode
  unlocked if the call might block. Force a non-blocking close if
  VXLOCK is set.  This eliminates a potential deadlock situation, and
  should eliminate the dirty buffers on reboot issue.

In spec_close(), if we're not doing a non-blocking close and VXLOCK is
not set, unlock the vnode before calling the device's close routine and
relock it after it returns. tty close routines will sleep waiting for
buffers to drain, which won't happen often times as the other side needs
to grab the vnode lock first.

Make all unmount routines lock the device vnode before calling VOP_CLOSE().

Add support for reading/writing FFS in non-native byte order, conditioned
to "options FFS_EI". The superblock and inodes (without blk addr) are
byteswapped at disk read/write time, other metadatas are byteswapped
when used (as they are acceeded directly in the buffer cache).
This required the addition of a "um_flags" field to struct ufsmount.
ffs_bswap.c contains superblock and inode byteswap routines also used
by userland utilities.
