1bc2362e07 o To support new EA interface with explicit namespaces, introduce two
utility functions which convert between string namespace names and
  numeric constants used by the interface.  Right now, two namespaces
  are supported, EXTATTR_NAMESPACE_SYSTEM ("system") and
  EXTATTR_NAMESPACE_USER ("user").  These functions are used by
  various userland EA utilities, rather than hard coding the routines
  all over the place.

70f3685105 o Change the API and ABI of the Extended Attribute kernel interfaces to
introduce a new argument, "namespace", rather than relying on a first-
  character namespace indicator.  This is in line with more recent
  thinking on EA interfaces on various mailing lists, including the
  posix1e, Linux acl-devel, and trustedbsd-discuss forums.  Two namespaces
  are defined by default, EXTATTR_NAMESPACE_SYSTEM and
  EXTATTR_NAMESPACE_USER, where the primary distinction lies in the
  access control model: user EAs are accessible based on the normal
  MAC and DAC file/directory protections, and system attributes are
  limited to kernel-originated or appropriately privileged userland
  requests.

o These API changes occur at several levels: the namespace argument is
  introduced in the extattr_{get,set}_file() system call interfaces,
  at the vnode operation level in the vop_{get,set}extattr() interfaces,
  and in the UFS extended attribute implementation.  Changes are also
  introduced in the VFS extattrctl() interface (system call, VFS,
  and UFS implementation), where the arguments are modified to include
  a namespace field, as well as modified to advoid direct access to
  userspace variables from below the VFS layer (in the style of recent
  changes to mount by adrian@FreeBSD.org).  This required some cleanup
  and bug fixing regarding VFS locks and the VFS interface, as a vnode
  pointer may now be optionally submitted to the VFS_EXTATTRCTL()
  call.  Updated documentation for the VFS interface will be committed
  shortly.

o In the near future, the auto-starting feature will be updated to
  search two sub-directories to the ".attribute" directory in appropriate
  file systems: "user" and "system" to locate attributes intended for
  those namespaces, as the single filename is no longer sufficient
  to indicate what namespace the attribute is intended for.  Until this
  is committed, all attributes auto-started by UFS will be placed in
  the EXTATTR_NAMESPACE_SYSTEM namespace.

o The default POSIX.1e attribute names for ACLs and Capabilities have
  been updated to no longer include the '$' in their filename.  As such,
  if you're using these features, you'll need to rename the attribute
  backing files to the same names without '$' symbols in front.

o Note that these changes will require changes in userland, which will
  be committed shortly.  These include modifications to the extended
  attribute utilities, as well as to libutil for new namespace
  string conversion routines.  Once the matching userland changes are
  committed, a buildworld is recommended to update all the necessary
  include files and verify that the kernel and userland environments
  are in sync.  Note: If you do not use extended attributes (most people
  won't), upgrading is not imperative although since the system call
  API has changed, the new userland extended attribute code will no longer
  compile with old include files.

o Couple of minor cleanups while I'm there: make more code compilation
  conditional on FFS_EXTATTR, which should recover a bit of space on
  kernels running without EA's, as well as update copyright dates.

fff8dac495 Fix make(1) bug: nested comments may be placed in .if, .else .if, and
.endif statements but can't be placed in .elif.  Basically, the problem
was that ParseSkipLine() didn't handle comments the same way that
ParseReadLine() did, and thus you had errors with comments that are on a
conditional line (i.e. "^.") rather than a non-conditional line.

b823bbd6be Fix a lock reversal problem in the VM subsystem related to threaded
programs.   There is a case during a fork() which can cause a deadlock.

From Tor -
The workaround that consists of setting a flag in the vm map that
indicates that a fork is in progress and using that mark in the page
fault handling to force a revalidation failure.  That change will only
affect (pessimize) page fault handling during fork for threaded
(linuxthreads style) applications and applications using aio_*().

f5161237ad o Implement "options FFS_EXTATTR_AUTOSTART", which depends on
"options FFS_EXTATTR".  When extended attribute auto-starting
  is enabled, FFS will scan the .attribute directory off of the
  root of each file system, as it is mounted.  If .attribute
  exists, EA support will be started for the file system.  If
  there are files in the directory, FFS will attempt to start
  them as attribute backing files for attributes baring the same
  name.  All attributes are started before access to the file
  system is permitted, so this permits race-free enabling of
  attributes.  For attributes backing support for security
  features, such as ACLs, MAC, Capabilities, this is vital, as
  it prevents the file system attributes from getting out of
  sync as a result of file system operations between mount-time
  and the enabling of the extended attribute.  The userland
  extattrctl tool will still function exactly as previously.
  Files must be placed directly in .attribute, which must be
  directly off of the file system root: symbolic links are
  not permitted.  FFS_EXTATTR will continue to be able
  to function without FFS_EXTATTR_AUTOSTART for sites that do not
  want/require auto-starting.  If you're using the UFS_ACL code
  available from www.TrustedBSD.org, using FFS_EXTATTR_AUTOSTART
  is recommended.

o This support is implemented by adding an invocation of
  ufs_extattr_autostart() to ffs_mountfs().  In addition,
  several new supporting calls are introduced in
  ufs_extattr.c:

    ufs_extattr_autostart(): start EAs on the specified mount
    ufs_extattr_lookup(): given a directory and filename,
                          return the vnode for the file.
    ufs_extattr_enable_with_open(): invoke ufs_extattr_enable()
                          after doing the equililent of vn_open()
                          on the passed file.
    ufs_extattr_iterate_directory(): iterate over a directory,
                          invoking ufs_extattr_lookup() and
                          ufs_extattr_enable_with_open() on each
                          entry.

o This feature is not widely tested, and therefore may contain
  bugs, caution is advised.  Several changes are in the pipeline
  for this feature, including breaking out of EA namespaces into
  subdirectories of .attribute (this is waiting on the updated
  EA API), as well as a per-filesystem flag indicating whether
  or not EAs should be auto-started.  This is required because
  administrators may not want .attribute auto-started on all
  file systems, especially if non-administrators have write access
  to the root of a file system.
