Comment 13 for bug 1690485

OK, I think I've followed instructions here.

I built with the '#define SANDBOX_SECCOMP_FILTER_DEBUG 1'
uncommented. Recalling at long last that Ubuntu is Debian
(I use Red Hat/CentOS at work and get them confused), I
used 'dpkg-buildpackage -rfakeroot -uc -b' to do the build;
hope that's OK. I also found that I needed to comment away
the four'#include' lines that follow the
SANDBOX_SECCOMP_FILTER_DEBUG definition, or else I got
many errors relating to conflicting structure definitions.

Attached tarball 'ssd-test-20171025.tar.gz' contains 'sshd.log',
the result of running 'sudo sshd -p 2222 -ddd'. It also contains
an etc/ hierarchy that includes the current /etc/ssh/sshd_config
and the relevant files from /etc/pam.d. I also threw in the result
of 'strace -f' applied to that command, in case it helps narrow
the point of failure further. I took a quick troll through the
output, and I don't *think* I see it revealing more than a
few bytes of a private key.

Thanks for responding! I hope this stuff helps to move the walls
in on the problem.
