Tested this on master without the patch. A config with two "local"
statements, one UDP, one TCP, and "port-share" will always fail with
Jun 9 10:26:19 gentoo tun-tcp-p2mp[19994]: Options error: --port-share only
works in TCP server mode (--proto values of tcp-server, tcp4-server, or
tcp6-server)
(the order of "local" statements does not matter). With the patch, it
will happily bind both ports and portshare works...

tcp6-server:[2001:608:4:0:62e9:965e:fba9:3fef]:50046 Non-OpenVPN client
protocol detected
The code change is also quite straightforward - instead of checking only
"ce->proto" (which might be anything here), we need to walk list of
sockets and see if there is "any tcp socket". I also tested "2 TCP
sockets", and port-share works on either of them. Good :-)
Your patch has been applied to the master and release/2.7 branch (bugfix).
