6f1695d876 When giving examples of how to use extattrctl(8) to configure UFS1
attributes, use the current convention for attribute directory names
so that UFS_EXTATTR_AUTOSTART will work with them.

6afa779308 Make it clear that this applies only to UFS1 file systems, as UFS2 will
have native extended attributes rather than stacked extended attributes.
While I'm at it, make sure UFS_EXTATTR is not spelt FFS_EXTATTR.

8970738b86 o extattrctl initattr, when pre-allocating store for extended attributes,
computed a a chunksize that didn't include the extended attribute
  header.  This was a non-fatal error, in that it was just writing out
  zeros anyway, but did have the effect of not pre-allocating the
  right amount of disk space.  This fix calculates chunksize to include
  the attribute header.

1fec210a69 o Add a ``-o'' argument to initattr, which causes extattrctl to overwrite
the existing attribute file rather than aborting with an error.
o Useful if you want to reset the state of attributes on the system without
  allocating different disk blocks through deletion and recreation,
  for example, if you're doing benchmarks of extended attribute code. :-)

bbf0607700 Modify extended attribute protection model to authorize based on
attribute namespace and DAC protection on file:
	- Attribute names beginning with '$' are in the system namespace
	- The attribute name "$" is reserved
	- System namespace attributes may only be read/set by suser()
	  or by kernel (cred == NULL)
	- Other attribute names are in the application namespace
	- The attribute name "" is reserved
	- Application namespace attributes are protected in the manner
	  of the target file permission

o Kernel changes
	- Add ufs_extattr_valid_attrname() to check whether the requested
	  attribute "set" or "enable" is appropriate (i.e., non-reserved)
	- Modify ufs_extattr_credcheck() to accept target file vnode, not
	  to take inode uid
	- Modify ufs_extattr_credcheck() to check namespace, then enforce
	  either kernel/suser for system namespace, or vaccess() for
	  application namespace
o EA backing file format changes
	- Remove permission fields from extended attribute backing file
	  header
	- Bump extended attribute backing file header version to 3
o Update extattrctl.c and extattrctl.8
	- Remove now deprecated -r and -w arguments to initattr, as
	  permissions are now implicit
	- (unrelated) fix error reporting and unlinking during failed
	  initattr to remove duplicate/inaccurate error messages, and to
	  only unlink if the failure wasn't in the backing file open()

3b88d2796e o Correct getopt() argument so that initattr -r and -w take an additional
argument via optarg.  This corrects a segfault when initattr is invoked
  with either of these two arguments.  Not sure how this got broken given
  that in the original patches it was fine -- presumably a merging
  mistake.

6c50ada1bd o Update extattrctl.8 to reflect new initattr -p, -r, and -w options.
o Update extattrctl.c to default new attributes to readable and writable
  only by the kernel and root user.  Previously the default was to allow
  the file owner to directory view and manipulate the attributes, which
  is probably an inappropriate default.

2a60effdd8 o Allow the ``-p'' argument to be specified to initattr, which indicates
that space for extended attributes should be preallocated, instead of
  using a sparse attribute file.  NOTE: This can result in a really
  large file full of zeros.  However, it can prevent a low disk condition
  from causing an attribute write to fail, which is good for security and
  consistency attributes.

o Unlink the attribute file during initattr if an error occurs -- this is
  alright, as we specify O_CREAT when opening the file.

9754f5b65b Introduced /usr/sbin/extattrctl, a utility for managing UFS/FFS extended
attributes (recently committed).  Using extattrctl, the extended attribute
service may be started and stopped for specific file systems; specific
attributes may be enabled or disabled, and the backing file for each
attribute configured.  Also, backing files may be initialized.
