RHBA-2014:1551 - Bug Fix Advisory

Topic

Updated rdma packages that fix several 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.

Several components provided by the rdma packages have been upgraded to newer
upstream versions that provide a number of bug fixes and enhancements. The
following components have been upgraded: infiniband-diags, libmlx4, libmlx5,
libibverbs, libibverbs-utils, librdmacm, librdmacm-utils, ibutils, libibmad,
libibumad, libipathverbs, libmthca, infiniband-diags, libibcommon, mstflint,
mvapich2, openmpi, opensm, osu-micro-benchmarks, perftest, qperf, and srptools.
(BZ#1053488, BZ#1087968, BZ#1093468, BZ#1087968, BZ#1053500, BZ#1051290,
BZ#1051211, BZ#1055654, BZ#1053391, BZ#1059093, BZ#1056662, BZ#1059093,
BZ#1059094, BZ#1059095, BZ#102730, BZ#1082730)

This update also fixes the following bugs:

• Prior to this update, the rping utility from the librdmacm-utils package

failed to establish an RDMA connection after accepting a connection request from
the client. This bug has been fixed and rping now creates connections as
expected in the described case. (BZ#828074)

• Under certain circumstances, the udaddy utility from the librdmacm-utils

package became unresponsive while receiving data transfers. This bug has been
fixed and udaddy no longer hangs in the aforementioned scenario. (BZ#828082)

• Previously, the ib_qib kernel module initialized certain mezzanine cards using

a kernel module parameter. However, the support for this method of
initialization has been deprecated and removed upstream, and was therefore
removed from the Red Hat kernel in a previous update. As a consequence, the
initialization of certain mezzanine cards no longer succeeded. With this update,
a modprobe configuration file is provided by the libipathverbs library that
enables the proper configuration of the ib_qib module from user space. As a
result, the affected mezzanine cards now initialize as expected. (BZ#1024903)

• Previously, the shared OpenType font library “libotf.so.0” was provided by

both the openmpi package and the libotf package. Consequently, when an RPM spec
file requested libotf.so.0 in order to operate properly, Yum could install
either openmpi or libotf to satisfy the dependency. However, as these two
packages do
not provide compatible libotf.so.0 libraries, the program either worked or not
depending on whether or not the right provider was selected. The libotf.so.0 in
openmpi is not intended for other applications to link against, it is an
internal library. With this update, libotf.so.0 in openmpi is excluded from RPM
library identification searches. As a result, applications linking
against libotf will get the right libotf, and openmpi will not accidentally be
installed to satisfy the need for libotf. (BZ#1097290)

In addition, this update adds the following enhancements:

• This update adds XRC support to InfiniBand stack and ConnectX devices from the

libibverbs package. (BZ#854655)

• This update adds support for the InfiniBand specification to the openmpi

package. (BZ#1005352)

• This update adds a libocrdma package that provides a device-specific userspace

driver for Emulex One Command RoCE Adapters to be used with the libibverbs
library.
(BZ#1080183)

• This update adds the mpich package that provides a high-performance and

widely portable implementation of the MPI standard (MPI-1, MPI-2 and MPI-3).
(BZ#1091537, BZ#1100557, BZ#1130083)

Users of rdma are advised to upgrade to these updated packages, which fix these
bugs and add these enhancements.
