[openib-general] IPoIB still not working

[Eitan Zahavi]

Hi Woody,

ERR 1B11 means as it says:
The expected component mask for the join is not sufficient.
Quoting from your mail:
>> osm_mcmr_rcv_join_mgrp: ERR 1B11: method = SubnAdmSet,scope_state = 0x1, 
>> component mask =0x0000000000010083, expected comp mask =
0x00000000000130c7.

Seems the component mask being sent is missing bits: 12,13 (starting from
0).
These are the 2^12 = SL and 2^13 = FlowLabel.
Please see the following spec quote:
o15-0.2.2: If SA supports UD multicast, then SA shall create a multicast
group if it receives a SubnAdmSet() method for a MCMemberRecord, with
the MGID set to 0 and the MCMemberRecord:JoinState.FullMember bit
set to 1. The required components in the MCMemberRecord for the group
to be created are P_Key, Q_Key, SL, FlowLabel, TClass, JoinState and
PortGID (see o15-0.1.3:) with the corresponding bits in the Component-
Mask set. All other components may be wildcarded. This results in an
implicit
join for the port specified by PortGID.

In osm_sa-mcmember_record.h you can find:
#define REQUIRED_MC_CREATE_COMP_MASK	|\
(IB_MCR_COMPMASK_MGID		| \
IB_MCR_COMPMASK_PORT_GID	| \	
IB_MCR_COMPMASK_JOIN_STATE	| \		
IB_MCR_COMPMASK_QKEY		| \		
IB_MCR_COMPMASK_TCLASS		| \
IB_MCR_COMPMASK_PKEY		| \
IB_MCR_COMPMASK_FLOW		| \
IB_MCR_COMPMASK_SL)

I found the problem with parsing of ScopeState. It appears that there
was a bug
in ib_types.h in the sourceforge code base. This was already fixed in
the latest Mellanox code base. However, with that fixed, I still get the
following
error from opensm when ipoib tries to join the multicast group. 
This is the dump from the latest mellanox opensm.
