           Summary: [ssh] [patch] Extra IP number information for failed

log ip-numbers for failed socket connect attempts

Running ssh, logfiles are swamped with lines like:
fatal: Read from socket failed: Connection reset by peer [preauth]

Which is rather useless for tools like sshguard and/or fail2ban

But this patch changes this info to:
Aug  2 19:37:32 zfs sshd[19444]: Read from socket failed: 218.2.22.36 [preauth]
Aug  2 19:37:32 zfs sshd[19444]:fatal: Read from socket failed: Connection
reset by peer [preauth]

I decided to keep the older log line as well, to keep consistent what was there
already. I do not know if any logfile analysers care about this line.

Thus giving other tools to opportunity to act on (now) known abuse ip-numbers.

PS: not sure if the patch goes to FreeBSd, or perhaps upstream to openssh?
