The ZFS update to onnv_141 brought with it support for a
security label attribute called mlslabel. This feature
depends on zones to work correctly and while I originally
added minimal support for this in libspl that was a mistake.
Supporting this under Linux is not required and this is
just additional troublesome code to support. Long term
something like this could be supported under Linux but it
will need to be clearly thought through them an implemented.
Added print_timestamp() compatibility function, this will be needed
long term but it's a simply enough addition.
Added Solaris style label functions. This was done simply to aid in
the initial update to onnv_141. I'm hopeful that after more careful
inspection all of this can be removed and we can integrate with a
more Linux friendly Solution without breaking any compatibility.
Added several missing headers which are required by the updated
version of ZFS. As usual I just add empty headers if needed because
it's easier than tracking the change against the core ZFS code.
Added SEC, MILLISEC, MICROSEC defines if unavailable.
Added missing xuio structure and typedefs. I'm hopeful these can
be removed as well once we crack the zero-copy nut under Linux.
These changes lay some of the ground work for supporting something
similar to FMA event under Solaris. In particular these changes
add or modify the following areas.
First off an implementation of the gethrestime() function is added
to libspl. Secondly, the missing type processorid_t has been added.
And finally the lib/libspl/include/sys/fm/{protocol.h|util.h} stub
headers have been removed in favor of updating the full versions
in module/zfs/include/sys/fm/{protocol.h|util.h} to work cleanly
in both user and kernel space.
- Add 64-bit user space atomic support obtained from an old version
of OpenSolaris which supported ppc. They are not all 100% fully
implemented by they are a good first step.
- Add powerpc ISA type.
- Strip out unused ISA defines to prevent any confusion.
