    <pinotree> basically, i'm trying to implement socket credentials for local
      sockets, and i guessed doing it in pflocal would be the appropriate place
    <pinotree> what i thought was filling the cmsg data for MSG_CRED at
      S_socket_recv() call
    <pinotree> in case i missed it, would there be a way to "identify" the
      other side of the port associated to the sock_user of that call?
    <pochu> pinotree: that's needed by dbus right? cool! (and I don't know)
    <pinotree> (yes, and gamin)
    <youpi> pinotree: you have them already, they're just not stored
    <youpi> see S_io_reauthenticate
    <youpi> Throw away the ids we went through all that trouble to get...
    <youpi> (comment)
    * pinotree looks
    <pinotree> hm, and who calls that rpc?
    <youpi> everybody
    <youpi> since that's how ext2fs knows the permission to apply, for instance
    <pinotree> ah, i was referring to the reauthenticate of pflocal, not
      auth_server_authenticate()
    <youpi> that's what I'm saying
    <youpi> see __hurd_file_name_lookup_retry, which is the very internal part
      of open()
    <youpi> it calls io_reauthenticate()
    <youpi> to authenticate itself to the underlying translator of the opened
      node
    <pinotree> youpi: so, hm, could be an option make the result of pflocal's
      S_io_reauthenticate cached in the sock_user struct?
    <youpi> yes
    <pinotree> nice thanks, i will try that change first
