Subject: [PATCH net-next 0/3] sctp: add support for some msg_control options from RFC6458

From: Xin Long <[email-masked]>

This patchset is to add support for 3 msg_control options described
in RFC6458:

    5.3.7.  SCTP PR-SCTP Information Structure (SCTP_PRINFO)
    5.3.9.  SCTP Destination IPv4 Address Structure (SCTP_DSTADDRV4)
    5.3.10. SCTP Destination IPv6 Address Structure (SCTP_DSTADDRV6)

one send flag described in RFC6458:

    SCTP_SENDALL:  This flag, if set, will cause a one-to-many
    style socket to send the message to all associations that
    are currently established on this socket.  For the one-to-
    one style socket, this flag has no effect.

Note there is another msg_control option:

    5.3.8.  SCTP AUTH Information Structure (SCTP_AUTHINFO)

It's a little complicated, I will post it in another patchset after
this.

Xin Long (3):
  sctp: add support for PR-SCTP Information for sendmsg
  sctp: add support for SCTP_DSTADDRV4/6 Information for sendmsg
  sctp: add support for snd flag SCTP_SENDALL process in sendmsg
