Samba 4.8.x in Ubuntu Cosmic 18.10

[Andreas Hasenack]

We are approaching feature freeze, and I wanted to highlight again the
issue we have with samba 4.8.x in Ubuntu.

This forum post has details:
https://discourse.ubuntu.com/t/samba-4-8-x-in-ubuntu-cosmic-18-10/7276

I'm going to paste its contents here as well:

I have a samba-4.8.2 build for cosmic in my PPA
(https://launchpad.net/~ahasenack/+archive/ubuntu/samba-merge-4.8-1778125)
that went through review and almost all was good, except for a
regression that one of our test suites caught:
https://bugzilla.samba.org/show_bug.cgi?id=134862 (also filed with
debian at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=9024311).

The bug has a test case attached, and it’s simple to reproduce.
Basically a guest connection cannot read the file it created itself if
its mode is 0600 (much less write to it). That’s the case with a file
created with mkstemp(), for example (or mktemp in the shell).

This is what is holding updating samba to 4.8.x in Ubuntu Cosmic at
the moment, and I was wondering if others would be hit by this
problem, or if you have seen this already after you upgraded to 4.8.x
by yourself.

I could upload it with this bug, but it would be bad if all of a
sudden I had to revert it and downgrade the package again.

If you are willing to give those packages in the PPA a try, that would
also be appreciated.

Thanks
