openssh unix dev - Jun 2023 - [feature suggestion] sshd should log the listening port number while logging errors/warnings

I have sshd listening on several ports for various reasons.


sshd periodically logs errors like these:

 > Jun? 4 22:52:52 xx sshd[30708]: error: 
Fssh_kex_exchange_identification: banner line contains invalid characters


This message would be a lot more helpful if it would contain the port 
number for this connection.

It would be easier to figure out where offending connections come from.


Thanks,

Yuri

The subsequent log line from sshpkt_fatal contains the source address
and port of that connection:

$ sudo `pwd`/sshd -ddd -p 2022
[...]
kex_exchange_identification: banner line contains invalid characters
banner exchange: Connection from 127.0.0.1 port 52410: invalid format
