Hi:

I found a formatting bug in the 4.1.1 ss command. The following line was
incorrectly output due to passing a negative length to printf() when
displaying the local address. In this instance hostapd does a "bind to
device" on cdreth0 and then does a udp "in address any" port 67 bind.
Please note the whitespace between the '*' and ' %cdreth0:67'

    'udp UNCONN 0 0 ** %cdreth0:67* *:* users:(("hostapd",pid=19241,fd=5))'

Attached is my patch for the bug fix, it might be prudent to add more
guard code looking for negative length format codes.

Sincerely, Mike
