    ss: support closing inet sockets via SOCK_DESTROY. · fb2594c1
    Lorenzo Colitti authored
    This patch adds a -K / --kill option to ss that attempts to
    forcibly close matching sockets using SOCK_DESTROY.
    
    Because ss typically prints sockets instead of acting on them,
    and because the kernel only supports forcibly closing some types
    of sockets, the output of -K is as follows:
    
    - If closing the socket succeeds, the socket is printed.
    - If the kernel does not support forcibly closing this type of
      socket (e.g., if it's a UDP socket, or a TIME_WAIT socket),
      the socket is silently skipped.
    - If an error occurs (e.g., permission denied), the error is
      reported and ss exits.
