Sean Hefty is upstream for librdmacm and he should have a git repo under his name. OFED pretty much takes his stuff unmodified, so there is no specific OFED repo for librdmacm. There are other things OFED pulls unmodified too, so it's not that they change all the packages they include, just some. However, there are actually a few things that only come from OFED and don't have their own repo or tarball release outside of their tarball in the larger OFED tarball. In those cases I have to grab it from OFED, sometimes modify it to work with pristine upstream, then package that up (qperf is an example, it's written to work with OFED libibverbs and assumes that is what it's compiled against, so I had to back out XRC support from day one to make it work with upstream libibverbs...they didn't even bother to conditionalize XRC support in qperf prior to it being accepted upstream in libibverbs). -- Doug Ledford <dledford@xxxxxxxxxx> GPG KeyID: CFBFF194 http://people.redhat.com/dledford Infiniband specific RPMs available at http://people.redhat.com/dledford/Infiniband
