[LU-3617] configure incorrectly finds no for RDMA events 14 and 15 on latest RHEL5

Description

We ran into an issue at Yale recently where the Lustre servers all got RDMA_CM_EVENT_TIMEWAIT_EXIT, which the servers didn't recognize and LBUGed on. There are two problems here. The first is that configure clearly doesn't do the right thing anymore, and the second is that Lustre shouldn't LBUG if it gets those events, even if configure doesn't find them.

I double checked on your build systems to make sure it wasn't just ours:
http://build.whamcloud.com/job/lustre-b1_8/arch=x86_64,build_type=server,distro=el5,ib_stack=inkernel/258/consoleFull

That's the official 1.8.9 build console if I'm not mistaken, and you can see:
checking if OFED has RDMA_CM_EVENT_ADDR_CHANGE... no
checking if OFED has RDMA_CM_EVENT_TIMEWAIT_EXIT... no

While the symptoms are the same, this is not the same issue. LU-3166 is configuration issues with OFED-3.5, this one is for RHEL's in-kernel OFED. I think it should be reopened as the solution is going to be different.

This is a duplicate of 3166, which tracks the same issue for release 2.5

Both test fail from the same thing.

So yes vlan_dev_vlan_id is located in fc_compact.h

James, can you please look at the questions I just posted on Gerrit?

[James A Simmons]

I'm seeing Lustre initialization errors in Maloo. The logs are not very informative so does anyone know what is going wrong?

[James A Simmons]

We just ran into this problem on our production systems. No detecting certain features can cause a Oops. I have a patch that fixes this problem at

Sorry the patch points to the original ticket I filed.

[Kit Westneat (Inactive)]

That is correct. It is RHEL 5.9, with the in-kernel RDMA.

[Andreas Dilger]

It looks like this is RBEL 5. What version of RHEL, and what version of OFED?
