Created attachment 689373 [details, diff] keep_moving_auth_get_canonical_hostname_to_canohost.patch patch attached. summary of problem from comment at top of patch: # 20210304 can't build net-misc/openssh-8.5_p1 without patching -- # /usr/portage/net-misc/openssh/files/openssh-8.2_p1-GSSAPI-dns.patch moved remote_hostname() and auth_get_canonical_hostname() # from auth.c to canohost.c, so that they are included in libssh.a, but # /usr/portage/net-misc/openssh/files/openssh-8.5_p1-GSSAPI-dns.patch leaves them in auth.c, # which isn't part of libssh.a, so that linking ssh-keysign fails.
