[ewg] NFS/RDMA backport for OFED 4.8-1 part 3

[David Z. Dai]

Hi, Vlad, Jeff:
Today I got the latest daily build from:
http://downloads.openfabrics.org/OFED/ofed-4.8-1-daily/OFED-4.8-1-20170905-0757.tgz 
This latest daily build includes the NFSoRDMA functionality now.

I did a full install on RHEL 7.3 LE OS:
[root at rhel73_host1_guest1_local_htx OFED-4.8-1-20170905-0757]# uname -a
Linux rhel73_host1_guest1_local_htx 3.10.0-514.el7.ppc64le #1 SMP Wed Oct 19
11:27:06 EDT 2016 ppc64le ppc64le ppc64le GNU/Linux

[root at rhel73_host1_guest1_local_htx OFED-4.8-1-20170905-0757]# ./install.pl  --all

The installation finished successfully.

They are not in "nfsrdma" rpm any more. They are now in "compat-rdma" rpm:
[root at rhel73_host1_guest1_local_htx OFED-4.8-1-20170905-0757]# rpm -qf
/lib/modules/3.10.0-514.el7.ppc64le/updates/net/sunrpc/xprtrdma/rpcrdma.ko

[root at rhel73_host1_guest1_local_htx OFED-4.8-1-20170905-0757]# rpm -qf

[root at rhel73_host1_guest1_local_htx OFED-4.8-1-20170905-0757]# ls -al /lib/modules/3.10.0-514.el7.ppc64le/updates/net/sunrpc/xprtrdma/rpcrdma.ko
-rw-r--r--. 1 root root 6031120 Sep  5 14:24 /lib/modules/3.10.0-514.el7.ppc64le/updates/net/sunrpc/xprtrdma/rpcrdma.ko
[root at rhel73_host1_guest1_local_htx OFED-4.8-1-20170905-0757]# ls -al /lib/modules/3.10.0-514.el7.ppc64le/updates/net/sunrpc/xprtrdma/rpcrdma.ko

However I see the error during module load time:
[root at rhel73_host1_guest1_local_htx OFED-4.8-1-20170905-0757]# modprobe xprtrdma
modprobe: ERROR: could not insert 'rpcrdma': Exec format error
[root at rhel73_host1_guest1_local_htx OFED-4.8-1-20170905-0757]# modprobe svcrdma
modprobe: ERROR: could not insert 'rpcrdma': Exec format error


NOTE:
1) Both xprtrdma and svcrdma are using same "rpcrdma.ko"  (see modinfo output above)
2) The mode of "rpcrdma.ko" is 644. Should it be at least 744?

Could you please check on this?

Thanks! - David
