+ * Thu Apr 20 2023 Dmitry Belyavskiy <dbelyavs@redhat.com> - 8.7p1-30

+ - Some non-terminating processes were listening on ports.

+   Resolves: rhbz#2177768

+ - On sshd startup, we check whether signing using the SHA1 for signing is

+   available and don't use it when it isn't.

+ - On ssh private key conversion we explicitly use SHA2 for testing RSA keys.

+ - In sshd, when SHA1 signatures are unavailable, we fallback (fall forward :) )

+   to SHA2 on host keys proof confirmation.

+ - On a client side we permit SHA2-based proofs from server when requested SHA1

+   proof (or didn't specify the hash algorithm that implies SHA1 on the client

+   side). It is aligned with already present exception for RSA certificates.

+ - We fallback to SHA2 if SHA1 signatures is not available on the client side

+   (file sshconnect2.c).

+ - We skip dss-related tests (they don't work without SHA1).
