Remember to test on the Mac build. About a year ago I moved the host side
tools over to upstream libselinux, but had to revert because it broke the
Mac build in multiple places. Since then Richard Haines has done a lot of
work to reduce the diff between upstream and the Android fork. Hopefully
that will reduce your effort.

Yeah I'm quite concerned about the Mac build, does anyone on here have
access to a Mac for testing?

I do, let me know when you have a branch you need looked at and I'll try to get to it.

So I have been working the last couple of days to understand what it
would take to kill external/libselinux (the Android Fork) and fixup
upstream so most of the delta is in. The only thing we would keep on
the Android side, is android.c and .h. Since those files are self
contained, we should just be able to merge upstream without concerns
of conflict. If we really wanted to, we could spin off a separate
libselinux-android that builds those two files and links to
libselinux, but that seems overkill IMHO.

The work is available here:
https://github.com/williamcroberts/selinux/tree/fork-kill

Currently to Build:
1. remove external/libselinux
2. apply this patch to bionic if not present:
https://android-review.googlesource.com/#/c/276918
3. either set external/selinux to my fork-kill branch or merge selinux
upstream master into external/selinux and apply the two patches listed
below:

Patches that matter ( I don't know how to make pretty little git
summaries):
commit e017f48acd2791a6aa62b4ed0c0b44256b26651f

libselinux: add The Android fork files

commit f40d7facbcaf1337f37b5630b98806fd25b1dbf9
Author: William Roberts<william.c.roberts@xxxxxxxxx>

libselinux: rectify the Android fork

The goal would be to upstream commit f40d7facb and leave
commit e017f48ac on the Android tree.

I am going to do some further testing tomorrow, and plan on submitting
the upstream patch f40d7facbc on Monday. If anyone wants to leave
preliminary feedback, or has a specific thing they want tested, let me
know.
Currently tested on the emulator and checked that the digest mechanism
for
last restorecon value is working.

FYI I may rebase that branch at anytime... you have been warned :-P
