>Synopsis: ssh anoncvs regression: Connection closed
>Category: user
>Environment:
System : OpenBSD 7.0
Details : OpenBSD 7.0-current (GENERIC) #198: Sat Dec 25 16:22:02
MST 2021
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC
Architecture: OpenBSD.amd64
Machine : amd64
>Description:
I have an anoncvs instance that stopped working upon upgrading to
-current. This looks like a regression with openssh, which closes the
connection.
$ cvs -d [email protected]:/cvs checkout -P nvi/
Connection closed by 45.77.165.128 port 22
cvs [checkout aborted]: end of file from server (consult above messages if any)
I expect something like:
$ cvs -d [email protected]:/cvs checkout -P nvi/
cvs server: /cvs/CVSROOT/config: unrecognized keyword 'UseNewInfoFmtStrings'
cvs server: Updating nvi
U nvi/exrc
U nvi/nexrc
cvs server: Updating nvi/snippets
U nvi/snippets/bsd.c
U nvi/snippets/for1.c
U nvi/snippets/for2.c
U nvi/snippets/inc.pl
...
>How-To-Repeat:
1. Host anoncvs following: https://www.openbsd.org/anoncvs.shar
2. 7.0 -stable works.
3. Update to 7.0 -current and existing setup stops working.
More minimal:
1. Create a passwordless account (e.g., puffy) similar to:
anoncvs::32766:32766::0:0:Anonymous CVS User:/open/anoncvs:/open/anoncvssh
2. usermod -p "" puffy
3. /etc/ssh/sshd_config
Match User puffy
PermitEmptyPasswords yes
AllowTcpForwarding no
AllowAgentForwarding no
X11Forwarding no
PermitTTY no
>Fix:
I found a workaround by downgrading with cvs -qD dates of revision 578-582 of
sshd.c. Then, use the sshd binary in /etc/rc.d/sshd as the daemon (e.g.,
daemon="/usr/sbin/sshd.581").
I am not sure how to bisect further because I probably have to update
/usr/libexec/ssh-*, /usr/sbin/sshd and /usr/bin/ssh* to do it correctly.
Two verbose logs with ssh follow along with dmesg/usbdevs at the end.
