Sasha,
There's a hack in the SM to deal with TopSpin's non-compliant
join compmask for IPoIB v4 multicast group ff12:401b:<pkey>::1
The group is pre-defined and maintained as a well-known multicast
group.
opensm/osm_prtn.c:
232 /* workaround for TS */
233 /* FIXME: remove this upon TS fixes */
234 mc_rec.mgid = osm_ts_ipoib_mgid;
235 memcpy(&mc_rec.mgid.raw[4], &pkey, sizeof(pkey));
236 /* Scope in MCMemberRecord (if present) needs to be consistent
with MGID */
237 mc_rec.scope_state = ib_member_set_scope_state(scope,
IB_MC_REC_STATE_FULL_MEMBER);
238 ib_mgid_set_scope(&mc_rec.mgid, scope);
239
240 status = osm_mcmr_rcv_find_or_create_new_mgrp(p_sa, comp_mask,
&mc_rec,
241 &p_mgrp);
242 if (p_mgrp) {
243 p_mgrp->well_known = TRUE;
244 if (!p->mgrp)
245 p->mgrp = p_mgrp;
246 }
As far as I can tell, this was added before git history.
Any idea if it's still needed?
