	sys/ufs/ffs/ffs_snapshot.c: revision 1.155

ffs: apply the remaining ffs_snapshot.c part of this FreeBSD commit:
  commit 364ed814e7285c8216d8a201d3ab3674eb34ce29
  Author: Kirk McKusick <mckusick@FreeBSD.org>
  Date:   Thu Dec 9 21:24:00 2004 +0000
    Fixes a bug that caused UFS2 filesystems bigger than 2TB to
    prematurely report that they were full and/or to panic the kernel
    with the message ``ffs_clusteralloc: allocated out of group''.
    Submitted by:   Henry Whincup <henry@jot.to>
    MFC after:      1 week

all the other changes in that commit were applied previously by others:
 - sborrill commmitted ffs_alloc.c rev 1.123 in 2009
 - simonb committed ffs_alloc.c rev 1.110 in 2008
 - the ffs_clusteralloc() part is not needed because we no longer have
   that function.

UVM locking changes, proposed on tech-kern:

- Change the lock on uvm_object, vm_amap and vm_anon to be a RW lock.
- Break v_interlock and vmobjlock apart.  v_interlock remains a mutex.
- Do partial PV list locking in the x86 pmap.  Others to follow later.

remove checks for failure after memory allocation calls that cannot fail:

  kmem_alloc() with KM_SLEEP
  kmem_zalloc() with KM_SLEEP
  percpu_alloc()
  pserialize_create()
  psref_class_create()

all of these paths include an assertion that the allocation has not failed,
so callers should not assert that again.

reorganize ffs_truncate()/ffs_indirtrunc() to be able to partially
succeed; change wapbl_register_deallocation() to return EAGAIN
rather than panic when code hits the limit

callers changed to either loop calling ffs_truncate() using new
utility ufs_truncate_retry() if their semantics requires it, or
just ignore the failure; remove ufs_wapbl_truncate()

this fixes possible user-triggerable panic during truncate, and
resolves WAPBL performance issue with truncates of large files

Stick ffs_ in front of the following macros:
   fragstoblks()
   blkstofrags()
   fragnum()
   blknum()

to finish the job of distinguishing them from the lfs versions, which
Christos renamed the other day.

I believe this is the last of the overtly ambiguous exported symbols
from ffs... or at least, the last of the ones that conflicted with lfs.
ffs still pollutes the C namespace very broadly (as does ufs) and this
needs quite a bit more cleanup.

XXX: boo on macros with lowercase names. But I'm not tackling that just yet.

- Try to keep snapshot indirect blocks contiguous.  This speeds up snapshot
  creation by a factor of ~3 and reduces the file system suspension time by
  a factor of ~5.

- Refine the scope of WAPBL transactions and the limit for deallocations in
  one transaction so we should no longer get a "wapbl_flush: current
  transaction too big to flush" panic when creating or removing snapshots
  on larger logging disks.

- fss(4): Allow FSSIOCSET to set the initial flags.  Add a new flag
  "FSS_UNLINK_ON_CREATE" to unlink the backing store before the snapshot
  gets created.  With this change dump(8) no longer dumps the zero-sized,
  but named snapshot it is working on.

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.

Revert previous commit.  Locking the snapshot vnode while the file system
is suspended extends the suspension until the vnode gets unlocked by
the caller of ffs_snapshot().

Resuming the file system before expunging all snapshots and syncing the
snapshot creates races and deadlocks with journaling file systems at least.

merge the bouyer-quota2 branch. This adds a new on-disk format
to store disk quota usage and limits, integrated with ffs
metadata. Usage is checked by fsck_ffs (no more quotacheck)
and is covered by the WAPBL journal. Enabled with kernel
option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem
basis. mount_mfs(8) can also turn quotas on.

Change the snapshot lock:
- No need to take the snapshot lock while the file system is suspended.
- Allow ffs_copyonwrite() one level of recursion with snapshots locked.
- Do the block address lookup with snapshots locked.
- Take the snapshot lock while removing a snapshot from the list.

While hunting deadlocks change the transaction scope for ffs_snapremove().
We could deadlock from UFS_WAPBL_BEGIN() with a buffer held.

Add a new inode flag, SF_SNAPINVAL, to be set on SF_SNAPSHOT inodes when
the snapshot is invalid.
Set SF_SNAPSHOT | SF_SNAPINVAL early when initializing a snapshot indode,
so that quota are bypassed for allocations on this inode.
Set SF_SNAPSHOT | SF_SNAPINVAL (instead of clearing SF_SNAPSHOT) when
expuge()ing a snapshot inode, so that userland tools working on the
snapshot (e.g. fsck or dump) can properly handle this inode.

The main point at this time is to have fsck_ffs -X properly compute quotas;
as a bonus persistent snapshots files won't show up in a dump(8) from a
snapshot.

This may also help speeding up taking snapshots, by bypassing expuge()
for snapshot inodes completely (but this needs more thoughs).


Briefly discussed with hannken@ in private mail.

Don't count snapshot files in inode quota too.
At umount time, chk?q may be called after quota have been shutdown,
as there is a final vflush pass after quota?_umount(); so skip quota
checks if the quota vnode is not there any more.

Do not update disk quotas for snapshot inodes, as this may require a

which will trigger another update to the same block.
Set SF_SNAPSHOT just after truncating the snapshot inode, so that this

Split ffs_freefile into a frontend for normal cylinder group and for
snapshot use. Adjust ffs_blkfree_common to get the fs instance passed
in, the original commit didn't account blocks in the snapshots
correctly. Assert that ffs_blkfree is used with the primary fs instance
and that ffs_checkfreefile is only used for snapshots. Move the bdwrite
from ffs_blkfree_common into the caller for symmetry. This creates a
redundant write of unmodified data for ffs_blkfree_snap if a double free
of a block happens.

ffs_blkfree is used in two different ways. The normal usage is to free a
block in the cylinder groups of the filesystem. The other user is the
snapshot code, which wants to modify the copied cylinder groups. Use
different frontends to distinguish the cases in preparation for fine
grained locking for cylinder groups.

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.

- Use async/delayed writes for snapshot creation and sync/uncache these buffers

- Remove um_snaplistsize. Was a duplicate of um_snapblklist[0].
- Byte swap the list of preallocated blocks on read/write instead of access.
- Always keep this list on ip->i_snapblklist so it may be rolled back when the
  newest snapshot gets removed. Fixes a rare snapshot corruption when using
  more than one snapshot on a file system.
ufs/ufsmount.h:
  - Make TAILQ_LAST() possible on member um_snapshots.

- Add flag L_COWINPROGRESS to struct lwp to avoid recursion when
  doing copy-on-write.

- Change VFS_SNAPSHOT() to return the snapshot vnode locked.

- Make the IO path for copy-on-write and snapshot-read more lightweight.
  Avoids deadlocks where vn_rdwr(...READ...) has a shared lock and needs
  to copy-on-write.
  Avoids deadlocks/panics where to clean pages the copy-on-write needs
  to allocate pages for its VOP_PUTPAGES().

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.
