563d336e44 Don't immediately return in ffs_fsync if there appears to be no data
to flush if it's a vnode on a softdep filesystem. softdep_sync_metadata
may still need to do some work.

31a775880b lfs_truncate: handle synlinks with length > maxsymlink_len as regular files.
For symlinks > 60 chars we were bzero'ing part of (struct inode) past the
actual inode struct, corrupting memory following the current (struct inode)
resuling in a 'panic: pool_get(lfsinopl): free list modified' later.
This could also be the cause of random panics. With this fix LFS seems to be
useable for me now.

61fa9e1409 Move vinvalbuf's check for dirty blocks into ffs_fsync, to ensure that
mode and ownership bits are flushed to disk before the vnode is
reclaimed.

The check, introduced in the softdep merge, assumes that if no blocks
are dirty, no file data *or metadata* needs to be flushed to disk.  This
is true of ffs, but is not true of lfs, and may not be true of other
filesystems.

Tested by myself and Bill Squier <groo@cs.stevens-tech.edu>.

dac789be22 Changes to stabilize LFS. The first two of these should also apply to the
1.4 branch.

* Use a separate per-fs lock, instead of ufs_hashlock, to protect the Inode
  free list.  This seems to prevent the "lockmgr: %d, not exclusive lock holder
  %d, unlocking" message I was mis-attributing last night to an unlocked vnode
  being passed to vrele.

* Change calling semantics of lfs_ifind, to give better error reporting:
  If fed a struct buf, it can report the block number of the offending inode
  block as well as the inode number.

* Back out rev 1.10 of lfs_subr.c, since the replacement code was slightly
  uglier while being functionally identical.

* Make lfs_vunref use the same free list convention as vrele/vput, so that
  vget does not remove vnodes from a hash list they are not on.

26c34e715f If ifile blocks were written before dirops were complete, and then the
system crashed, inodes could be allocated that were not referenced.  (Though
not a serious problem, it evidences itself in phase 4 of fsck_lfs.)  Fix
this by marking if_daddr with UNASSIGNED before the inodes are actually
written; at mount time the ifile is checked for UNASSIGNED entries and
any that are found are linked back into the free list.  (The latter
functionality should move into the roll-forward agent when it materializes.)

f058684b7f lfs_truncate calls vinvalbuf to invalidate all currently-hald buffers, which
in turn forces a flush of the vnode, whether or not it is involved in a dirop.
(This can happen during a remove or rmdir, when the directory is shrunk.)
Because of the nature of dirops, however, flushing a vnode involved in a dirop
is disallowed (and was marked with a panic).  This patch has lfs_truncate
call a specialized vinvalbuf that only invalidates buffers following the new
end-of-file, and thus does not require a flush.  Also the panic is demoted,
in case I missed any other path to lfs_vflush.

cffa290130 Since dirop vnodes can't be flushed, they hold a reference until their

if we are short on vnodes, lfs_vflush from another process can grab a
vnode that lfs_markv has already processed but not yet written; but
lfs_markv holds the seglock.  When lfs_vflush gets around to writing it,
the context for copyin is gone.  So, now lfs_markv calls copyin itself,

1b8f5ea3c3 New sources should leave the LFS in a more-or-less working state. Changes
include:

	- DIROP segregation is enabled, and greater care is taken
	  to make sure that a checkpoint completes.  Fsck is not
	  needed to remount the filesystem.
	- Several checks to make sure that the LFS subsystem does not
	  overuse various resources (memory, in particular).
	- The cleaner routines, lfs_markv in particular, are completely
	  rewritten.  A buffer overflow is removed.  Greater care is taken
	  to ensure that inodes come from where lfs_cleanerd say they come
	  from (so we know nothing has changed since lfs_bmapv was called).
	- Fragment allocation is fixed, so that writes beyond end-of-file
	  do the right thing.

651b44e211 Rework the way kernel include files are installed. In the new method,
as with user-land programs, include files are installed by each directory
in the tree that has includes to install.  (This allows more flexibility
as to what gets installed, makes 'partial installs' easier, and gives us
more options as to which machines' includes get installed at any given
time.)  The old SYS_INCLUDES={symlinks,copies} behaviours are _both_
still supported, though at least one bug in the 'symlinks' case is
fixed by this change.  Include files can't be build before installation,
so directories that have includes as targets (e.g. dev/pci) have to move
those targets into a different Makefile.

091dafd39f 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.

by userland utilities.

8c0a9bab00 Don't cast 64bit (off_t) file sizes to vm_offset_t (32bit on many
architectures), truncate them intelligently instead.
The truncation is done centralized in vnode_pager.c.
This prevents from wrap-over effects when parts of large (>2^32 byte) files
are mmapped.
Don't allow to mmap above the numerical range of vm_offset_t.
This is considered a temporary solution until the vm system handles the
object sizes/offsets more cleanly.

76c414a957 Add support for ext2fs, this needed a few modifications to ufs/ufs/inode.h:
- added an "union inode_ext" to struct inode, for the per-fs extentions.
  For now only ext2fs uses it.
- i_din is now an union:
	union {
		struct  dinode ffs_din; /* 128 bytes of the on-disk dinode. */
		struct ext2fs_dinode e2fs_din; /* 128 bytes of the on-disk dinode. */
	} i_din
  Added a lot of #define i_ffs_* and i_e2fs_* to access the fields.
- Added two macros: FFS_ITIMES and EXT2FS_ITIMES. ITIMES calls the rigth
  macro, depending on the time of the inode. ITIMES is used where necessary,
  FFS_ITIMES and EXT2FS_ITIMES in other places.

90688fce27 Change the second and third args to struct vfsops' (*vfs_mount)() to
'const char *', and 'void *', respectively.  The second arg is taken directly
from user arguments, and is const there, so must be const in the prototypes
and functions.  The third arg is also taken directly from user arguments.
It doesn't have to be changed, but since it's cleaner to keep the type
the same as the user arg's type, and I'm already making the 'const char *'
change...

ebe1c82eda Make the struct lfs 512 bytes long on 32bit machines whose compiler doesn't
align 32bit integers. Use explicit sized typing at some other places.

XXX This still won't fix lfs for 64bit machines, as we have some
assumptions about sizeof(pointer)=sizeof(u_int32_t) in here, and (if I
looked right) a misaligned u_int64_t. The right fix (to cite cgd) will
be to seperate on-disk-representation from in-core, but I don't have
the time (at the moment) to do this.

f6e4567c57 cast int64_t-sized types to "long long" before printing them with %qd.
gcc thinks that the 'q' modifier describes a "long long", and so -Wformat
whines when printing with 'q' on the alpha, since int64_t-sized types are
done with variations on "long" rather than "long long".
