            Bug ID: 2792
           Summary: regress/authinfo.sh fails when tester's login shell is
                    not /bin/sh or compatible
           Product: Portable OpenSSH
           Version: 7.6p1
          Hardware: ix86
                OS: NetBSD
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Regression tests
          Assignee: unassigned-bugs at mindrot.org
          Reporter: openssh at vega.pgw.jp

Created attachment 3065

patch for authinfo.sh

In regression tests, regress/authinfo.sh assumes that
tester's login shell is /bin/sh or compatible.
The test tries
    ssh 127.0.0.1 'test -z "$SSH_USER_AUTH"'
but this will always fail when tester's login shell is /bin/csh,
emitting "SSH_USER_AUTH: Undefined variable.".

The attached patch will explicitly invoke "sh -c '....'",
which fixed the problem.

--- Comment #1 from Damien Miller <djm at mindrot.org> ---
We fixed this (twice!) before 7.7 was released. The current code looks
like:

env SSH_USER_AUTH=blah ${SSH} -F $OBJ/ssh_proxy x \
        'env | grep SSH_USER_AUTH >/dev/null' && fail
"SSH_USER_AUTH
present"
