9.6p1 test suite help
Hi OpenSSH,
I'm working on updating Guix's openssh package definition to the latest 
release. So far, I have only changed the version (and checksum) and left 
the build/test/install recipe the same. However, the test suite now fails. 
I could use some pointers to find out what exactly is going wrong with the 
failing test or how to fix it. I'm happy to provide more information about

Enforcing sha2 algorithm in ssh-keygen.c
Dear colleagues,
ssh-keygen uses SHA1 algorithm (default) when verifying that the key is
usable. It causes problems on recent systems where SHA1 is disabled for use
with signatures (at least, RHEL 9+).
The proposed patch enforces using a sha2 algorithm for key verification.

diffie-hellman-group-exchange-sha256 group size concerns and request
Hello all,
I have recently had cause to dig a little into the specifics of how 
diffie-hellman-group-exchange-sha256 group sizes work.
The belief in the wild, perpetuated by multiple sources of logjam 
mediation papers and also Andras Stribnik's very influential piece 
"Secure Secure Shell", is that server operators can force the use of a 
minimum group size by removing moduli

Defend against user enumeration timing attacks - overkill
Dear Peter,
I'm trying to balance the original problem statement (protection from
users enumeration) and avoid doubling time here if the process has
already taken a long time to provide faster auth method iteration.
I believe that a better solution is to set some arbitrary (probably
configurable) timeout and, in case when we spend more time than that
value, avoid doubling it.

Defend against user enumeration timing attacks - overkill
Dear colleagues,
I have a question about this commit:
https://github.com/openssh/openssh-portable/commit/e9d910b0289c820852f7afa67f584cef1c05fe95#diff-a25e40214ca9c9f78abce22f23bf2abdb2a24384c6610d60bbb314aed534eb48R216
The function ensure_minimum_time_since effectively doubles the time
spent in the input_userauth_request (mostly presumably in PAM). So if
PAM processing is really slow, it will
