RHEA-2011:1639 - Product Enhancement Advisory

Topic

Updated RDMA packages that fix various bugs and add various enhancements
are now available for Red Hat Enterprise Linux 6.

Description

Red Hat Enterprise Linux includes a collection of InfiniBand and iWARP
utilities, libraries and development packages for writing applications that use
Remote Direct Memory Access (RDMA) technology.

The following general upgrade has been performed:

• The InfiniBand/iWARP/RDMA stack components have been upgraded to more recent

upstream versions.

Also, these updated packages fix numerous bugs, including but not limited to the
following:

• The perftest, qperf, and srptool packages spec files erroneously limited the

32 bit Intel build to just the i386 architecture while Red Hat Enterprise Linux
6 now defaults 32 bit Intel builds to the i686 architecture. As a consequence
these packages failed to build on the i686 architecture. With this update the
error has been corrected and the packages build as expected. (BZ#724896,
BZ#724899, BZ#724900)

• In Red Hat Enterprise Linux 6.1 changes to network functions to support

multiple IP addresses on an interface were made. This caused the ifup-ib script
to fail to start IPoIB interfaces depending on how the ifcfg-ib[n] (where [n] is
0 or greater) file was written. Erroneous error messages, "Error: an inet prefix
is expected rather than" or "Error, some other host already uses address" were
logged. With this update, the ifup-ib script has been changed to handle an array
of multiple IP addresses and the error no longer occurs in the scenario
described. (BZ#721101)

In addition, these updated packages provide the following enhancements:

• This update provides support in OpenSM for Single Root I/O Virtualization

(SRIOV) using SRIOV ports exposed on Mellanox SRIOV capable devices. (BZ#633392)

• An OpenSM update was required in order to provide SRIOV support and the update

changed the names of the libraries exported by OpenSM and the rest of the
InfiniBand management stack. Therefore a new package, "compat-opensm-libs", that
provides a copy of the original libraries, was added to the stack to prevent
this upgrade from breaking installed applications. (BZ#725106)

All RDMA users should upgrade to these updated packages which fix these bugs and
add these enhancements.
