RHBA-2010:0292 - Bug Fix Advisory

Topic

Updated openib packages that fix various bugs and add various enhancements
are now available.

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:

• this update brings a number of packages in line with their latest

upstream versions. (BZ#518218)

Also, these updated packages fix the following bugs:

• even simple test code could not be compiled using mvapich if mvapich was

installed but certain other libraries were not. To correct this, the
mvapich rpm now Requires all libraries necessary to build an mpi program.
(BZ#479940, BZ#568449)

• when running openmpi jobs, many warnings would present related to udapl.

The issue is corrected by removing udapl support from openmpi. (BZ#479941,
BZ#526138, BZ#543453)

• openmpi did not support the latest Chelsio devices. This release corrects

that. (BZ#515567)

• a bug in IPoIB bonding could cause the kernel to panic during the reboot

of a system. The openibd init script has been modified to correct this bug.
(BZ#540992)

• in the update to openmpi-1.3.2, upstream changed the default value of SGE

support from enabled to disabled, which caused Red Hat's version of the
openmpi package to regress. These updated packages restore SGE support in
Red Hat's openmpi packages. (BZ#541660)

• the srp_daemon.conf configuration file was not in the "/etc" directory

where srp_daemon requires it to be. During installation the srp_daemon.conf
file was being placed in the incorrect directory of "/etc/ofed". This issue
is fixed by ensuring the srp_daemon.conf file is placed in the "/etc"
directory during installation. (BZ#552915)

• a regression was introduced in openmpi-1.3.3-6 that caused allreduce to

hang. This regression is now corrected with these updated packages and
allreduce functions as expected. (BZ#555159)

• a pseudo requirement has been added to the libibverbs package so that it

will automatically pull in the various libibverbs driver packages when
using yum to install libibverbs. (BZ#559789)

• Libmlx4 was missing device IDs that were present in the Red Hat

Enterprise Linux kernel. The missing device IDs have now been added to
libmlx4. These IDs are for MT26438 and MT26488. (BZ#569175)

the following enhancements were also added:

• Openmpi now supports iWARP devices. (BZ#515565)
• the OpenFabrics Alliance (OFED) drivers which support Mellanox MT25408

ConnectX series Infiniband devices were added. (BZ#511190)

All openib users should upgrade to these updated packages which resolves
these issues and adds these enhancements.
