Sorry New York Comic-Con started last Thursday, but now that it is
done, a compressed tar tree for SVMLS, System V/Multi-Level Security, the
Orange Book changes by Bell Labs' Whippany Federal Systems from mid 1988
has somehow appeared in the wild at
https://www.mediafire.com/file/7b5hp5gyl8k6uk4/svmls.tgz/file
But act fast, as it will only be available for the next 14 days and then
will be auto-deleted. It's small at under 200K, as it was intentionally
kept lean, with the kernel changes under uts/ (the orig files are there
too for an easy diff) and the security audit trail (sat) utilities
under cmd/
