Client fails kex after c38ea634893a1975dbbec798fb968c9488013f4a
I have a Putty variant that works well with openSSH up until 7.4. After
git bisecting I found that after the application of
c38ea634893a1975dbbec798fb968c9488013f4a the client fails with host key
mismatch. The commit in question appears to remove vestiges of ssh-1
support but my client is using 2.0. I am trying to work out what in that
commit would lead to the symptoms. I have been through the

Damien,
Thank you; that was an absolutely golden recommendation. Turning on SANDBOX_SECCOMP_FILTER_DEBUG was the magic, that did, in fact, uncover an unexpected system call violation:

[Bug 1487] New: Race condition between monitor and unprivileged child in sshd
...tted request 6
Damien Miller proposed setting up a pipe shared between the monitor and
child, and making the child wait until the monitor end closes, which
it should do after permitting the monitor calls.
I believe the pipe close (granting permission to continue) should be at
the end of monitor.c:mm_answer_sign, right after the line:
monitor_permit(mon_dispatch, MONITOR_REQ_PWNAM, 1);
Of course, I could be wrong. On the other hand, I have not been able to
figure out where to place the pipe read (waiting for permission) call.

Cisco vs. 6.9
After upgrading a Linux system from OpenSSH 6.7 to 6.9, Cisco
switches/routers can no longer scp config files to/from the system. The
last debug entry before the Cisco device closes the connection is "debug1:
server_input_channel_open: confirm session". The next line is "Connection
closed by x.x.x.x". Anyone else seen this or know of a fix? The Cisco
device gives
