I have a samba-4.8.2 build for cosmic in my PPA 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=13486 (also filed with debian at https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=902431).
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
