pimd: STAR inherited Flag not properly set in certain scenarios
Problem Statement:
==================
Mroutes are not recovered after shut/no shut of DUT to RP links
One interface is not added in OIL List in intermediate router,
hence traffic never received at LHR and mroutes not created for (S,G).
Root Cause Analysis:
====================
Generally (*,G) PIM Join is received first and then (S,G) joins are received.
This issue occurs when (S,G) join comes first and then the (*,G) Join.
When (S,G) PIM Join is received, ifchannel is created and channel_oil
OIF flag is set to PIM_OIF_FLAG_PROTO_PIM. Now when (*,G) join is received
the flag PIM_OIF_FLAG_PROTO_STAR is not inherited due to wrong check present in
function pim_upstream_inherited_olist_decide.
Fix:
===================
When (*,G) PIM Join is received, it should always add PIM_OIF_FLAG_PROTO_STAR
flag for all the (S,G) channel oils no matter what order the (*,G) or (S,G)
is received.
Fixes: #9918
