MFC: Use mount interlock to protect all changes to mnt_flag and

2006-10-09T19:47:17+00:00

     mnt_kern_flag. This eliminates a race where MNT_UPDATE flag could be
     lost when nmount() raced against sync(), sync_fsync() or quotactl().

  Remove calls to vfs_export() for exporting a filesystem for NFS mounting
  from individual filesystems.  Call it instead in vfs_mount.c,
  after we call VFS_MOUNT() for a specific filesystem.

MFC rev. 1.3: repair ext2fs writes.

Work around the shortness of the size argument to

2006-02-20T00:53:15+00:00

vnode_create_vobject() while preserving the binary ABI
to filesystem modules in RELENG_6: introduce a new function
vnode_create_vobject_off() that takes the size argument
as off_t; move all stock file systems to it; re-implement
the old vnode_create_vobject() using vnode_create_vobject_off()
so that old or binary-only FS modules can work w/o hitting the
bug.  The trick is to pass a size of 0 to vnode_create_vobject_off()
so that it will call VOP_GETATTR() and thus get the actual,
untruncated file size even if the calling module still uses
the old vnode_create_vobject().

Original commit message:
  Log:
  Apply the same fix to a potential race in the ISDOTDOT code in
  ext2_lookup() that was used to fix an actual race in ufs_lookup.c:1.78.
  This is not currently a hazard, but the bug would be activated by
  marking ext2fs as MPSAFE.

kern/87959      cracauer        ext2fs: no cp(1) possible, mmap returns EINVAL

ext2fs was missing vnode_create_vobject.

(Reisefs probably has the same problem but I want to get this in quick
for 6-release)
