Description Xin Long 2022-07-04 16:56:59 UTC

There are new chunks added in Linux SCTP not being traced by iptables, and we're planning to support them in iptables xt_sctp.

The patch has been posted by Yuxuan on: https://lore.kernel.org/all/20220629200545.75362-1-yuluo@redhat.com/T/

Will do, thanks again for your work upstream!

We're late for features in RHEL9.2, will postpone. Also one follow-up upstream:

    xt_sctp: add the missing chunk types in sctp_help
    
    Add the missing chunk types in sctp_help(), so that the help cmd can
    display these chunk types as below:
    
      # iptables -p sctp --help
    
      chunktypes - ... I_DATA RE_CONFIG PAD ... I_FORWARD_TSN ALL NONE
