This is an automated email from the git hooks/post-receive script.
djm pushed a commit to branch master
in repository openssh.
commit 95d41e90eafcd1286a901e8e361e4a37b98aeb52
Author: dtucker at openbsd.org <dtucker at openbsd.org>
Date: Thu Jul 19 10:28:47 2018 +0000
upstream: Deprecate UsePrivilegedPort now that support for running
ssh(1) setuid has been removed, remove supporting code and clean up
references to it in the man pages
We have not shipped ssh(1) the setuid bit since 2002. If ayone
really needs to make connections from a low port number this can
be implemented via a small setuid ProxyCommand.
