Subject: AF_UNIX shutdown
Date: Fri, 16 Oct 2020 08:55:19 -0400	[thread overview]
Message-ID: <a7166f01-7508-d097-96d8-7aa3b94c17b9@cornell.edu> (raw)

Hi Corinna,

I'm about to add some code to handle shutdown info, and I want to make sure that 
I understand how this is supposed to work.  fhandler_socket_unix::shutdown 
contains the following comment:

/* Send shutdown info to peer.  Note that it's not necessarily fatal
    if the info isn't sent here.  The info will be reproduced by any
    followup package sent to the peer. */

Does that mean that sendmsg should send its shutdown state as part of every 
packet it sends?

And I guess recvmsg should call grab_admin_pkg at every opportunity and should 
also check the shutdown state in every regular packet it reads?

Thanks.

Ken
