ufs: fixed signed/unsigned bugs affecting large file systems

Apply these commits from FreeBSD:
  commit e870d1e6f97cc73308c11c40684b775bcfa906a2
  Author: Kirk McKusick <mckusick@FreeBSD.org>
  Date:   Wed Feb 10 20:10:35 2010 +0000
    This fix corrects a problem in the file system that treats large
    inode numbers as negative rather than unsigned. For a default
    (16K block) file system, this bug began to show up at a file system
    size above about 16Tb.
    To fully handle this problem, newfs must be updated to ensure that
    it will never create a filesystem with more than 2^32 inodes. That
    patch will be forthcoming soon.

the UFS_EXTATTR option was supposed to affect only UFS1 file systems,
but when the UFS2 extattr code was merged, the UFS_EXTATTR option was
mistakenly changed to affect UFS2 file systems as well.  this commit
changes UFS_EXTATTR back to affecting only UFS1 file systems as originally
intended.  in UFS2 (or rather UFS2ea in NetBSD), extattrs are a
native feature and are always supported.

Disentangle buffer-cached I/O from page-cached I/O in UFS.

Page-cached I/O is used for regular files, and is initiated by VFS
users such as userland and NFS.

Buffer-cached I/O is used for directories and symlinks, and is issued
only internally by UFS.

New UFS routine ufs_bufio replaces vn_rdwr for internal use.
ufs_bufio is implemented by new UFS operations uo_bufrd/uo_bufwr,
which sit in ufs_readwrite.c alongside the VOP_READ/VOP_WRITE
implementations.

I preserved the code as much as possible and will leave further
simplification for future commits.  I kept the ulfs_readwrite.c
copypasta close to ufs_readwrite.c in case we ever want to merge them
back; likewise ext2fs_readwrite.c.

No externally visible semantic change.  All atf fs tests still pass.

Cleanup ffs fsync and make devices on wapbl enabled file systems work here:

- Replace the ugly sync loop in ffs_full_fsync() and ffs_vfs_fsync() with
  vflushbuf().  This loop is a relic of softdeps and not needed anymore.

- Add ffs_spec_fsync() for device nodes on ffs file systems that calls
  spec_fsync() like all other file systems do and then updates the ctime.

Discussed on tech-kern.

option QUOTA2 (added where QUOTA was enabled in kernel config files),
turned on with tunefs(8) on a per-filesystem

  (in plistref format) describing commands and arguments.
  For each command, status and data are returned as a prop_dictionary.
  quota commands features will be added to take advantage of this,
  exporting quota data or getting quota commands as plists.

- new on disk-format storage (all 64bit wide), integrated to metadata for
  ffs (and playing nicely with wapbl).
  Quotas are enabled on a ffs filesystem via superblock flags.
  tunefs(8) can enable or disable quotas.
  On a quota-enabled filesystem, fsck_ffs(8) will track per-uid/gid
  block and inode usages, and will check and update quotas in Pass 6.
  quota usage and limits are stored in unliked files (one for users,
  one for groups)l fsck_ffs(8) will create the files if needed, or
  free them if needed. This means that after enabling or disabling
  quotas on a filesystem; a fsck_ffs(8) run is required.
  quotacheck(8) is not needed any more, on a unclean shutdown
  fsck or journal replay will take care of fixing quotas.
  newfs(8) can create a ready-to-mount quota-enabled filesystem
  (superblock flags are set and quota inodes are created).
  Other new features or semantic changes:
  - default quota datas, applied to users or groups which don't already
    have a quota entry
  - per-user/group grace time (instead of a filesystem global one)
  - 0 really means "nothing allowed at all", not "no limit".
    If you want "no limit", set the limit to UQUAD_MAX (tools will
    understand "unlimited" and "-")

  A quota file is structured as follow:
  it starts with a header, containing a few per-filesystem values,
  and the default quota limits.
  Quota entries are linked together as a simple list, each entry has a
  pointer (as an offset withing the file) to the next.
  The header has a pointer to a list of free quota entries, and
  a hash table of in-use entries. The size of the hash table depends
  on the filesystem block size (header+hash table should fit in the
  first block). The file is not sparse and is a multiple of
  filesystem block size (when the free quota entry list is empty a new
  filesystem block is allocated). quota entries to not cross
  filesystem block boundaries.

  In memory, the kernel keeps a cache of recently used quota entries
  as a reference to the block number, and offset withing the block.
  The quota entry itself is keept in the buf cache.

fsck_ffs(8), tunefs(8) and newfs(8) supports are completed (with
related atf tests :)
The kernel can update disk usage and report it via quotactl(2).

Todo: enforce quotas limits (limits are not checked by kernel yet)
      update repquota, edquota and rpc.rquotad to the new world
      implement compat_50_quotactl ioctl.
      update quotactl(2) man page

fsck_ffs required fixes so that allocating new blocks or inodes will
properly update the superblock and cg sumaries. This was not an issue up
to now because superblock and cg sumaries check happened last, but now
allocations or frees can happen in pass 6.

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

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.

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).

- access the ffs and ext2fs itimes functions through a pointer, so that
  if the filesystem is not compiled in the kernel still links. Probably
  a better solution is to use weak symbols.
- move the filesystem-specific itime macros to the filesystem header files.

Use nanotime() to update the time fields in filesystems. Convert the code
from macros to real functions. Original patch and review from chuq.
Note: ext2fs only keeps seconds in the on-disk inode, and msdosfs does not
have enough precision for all fields, so this is not very useful for those
two.

Experimental support for extended attributes on UFS1 file systems, using a
backing file per attribute type indexed by inode number to hold the extended
attributes.

This is working pretty well on my test systems, except for the "autostart"
feature.  I need someone with a better handle on the VFS locking protocol
to go over that.

This is a work-in-progress.  There are parts of this that could be re-factored
allowing this approach to be used on other types of file systems.

- 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.

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.

Add code to UBCify LFS.  This is still behind "#ifdef LFS_UBC" for now
(there are still some details to work out) but expect that to go
away soon.  To support these basic changes (creation of lfs_putpages,
lfs_gop_write, mods to lfs_balloc) several other changes were made, to
wit:

* Create a writer daemon kernel thread whose purpose is to handle page
  writes for the pagedaemon, but which also takes over some of the
  functions of lfs_check().  This thread is started the first time an
  LFS is mounted.

* Add a "flags" parameter to GOP_SIZE.  Current values are
  GOP_SIZE_READ, meaning that the call should return the size of the
  in-core version of the file, and GOP_SIZE_WRITE, meaning that it
  should return the on-disk size.  One of GOP_SIZE_READ or
  GOP_SIZE_WRITE must be specified.

* Instead of using malloc(...M_WAITOK) for everything, reserve enough
  resources to get by and use malloc(...M_NOWAIT), using the reserves if
  necessary.  Use the pool subsystem for structures small enough that
  this is feasible.  This also obsoletes LFS_THROTTLE.

And a few that are not strictly necessary:

* Moves the LFS inode extensions off onto a separately allocated
  structure; getting closer to LFS as an LKM.  "Welcome to 1.6O."

* Unified GOP_ALLOC between FFS and LFS.

* Update LFS copyright headers to correct values.

* Actually cast to unsigned in lfs_shellsort, like the comment says.

* Keep track of which segments were empty before the previous
  checkpoint; any segments that pass two checkpoints both dirty and
  empty can be summarily cleaned.  Do this.  Right now lfs_segclean
  still works, but this should be turned into an effectless
  compatibility syscall.

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.

remove third argument (`int ns') from ffs_sb_swap(), and let ffs_sb_swap()
determine the endianness of the `struct fs *o' superblock from o->fs_magic
and set needswap as necessary, rather than trusting the caller to get
it right.  invariably, almost every caller of ffs_sb_swap() was calling it
with ns set to the wrong value for ns anyway!
ansi KNF ffs_bswap.c declarations whilst here.

this fixes all sorts of problems when trying to use other-endian file systems,
notably the kernel trying to access memory *way* off, possibly corrupting or
panicing, and userland programs SEGVing and/or corrupting things (e.g,
"fsck_ffs -B"  to swap a file system endianness).

whilst the previous rev of ffs_bswap.c (1.10, 2000/12/23) made this problem
worse, i suspect that the problem was always there and previous versions
just happened not to trash things at the wrong time.

FFS_EI should now be a lot more stable.

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.

For each leaf filesystem, add appropriate vfs_done routine.

Also remember how many times ffs_init() was called and do
the appropriate initialization on first call only. In ffs_done(),
destroy the resources when called by the last user of ffs code.
Change mfs to call ffs_init()/ffs_done() appropriately.
