Summary: mld6_leavegroup does not send ICMP6_TYPE_MLD, even
if last reporter
Project: lwIP - A Lightweight TCP/IP stack
Submitted by: lrevardel
Submitted on: Fri 03 Feb 2017 02:14:14 PM GMT
Severity: 3 - Normal
Item Group: Faulty Behaviour
Assigned to: None
Discussion Lock: Any
Planned Release: None
lwIP version: 2.0.0
mld6_leavegroup() should generate an ICMP6 packet (ICMP6_TYPE_MLD) when the
host is the last one that reported ICMP6_TYPE_MLR for the specified group.
This packet is never sent, even when the host is the last reporter.
group->last_reporter_flag is never set to one.
As done for IGMP, this flag could be set to one in mld6_send(), when the sent
packet is ICMP6_TYPE_MLR.
Tested version: STABLE-2_0_0_RC2
Behavior observed while attempting a group leave on FF15::1, after successful
group add and no other host on the network.
