RHBA-2015:1415 - 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.

The user space libcxgb4 driver has been upgraded to upstream version 1.3.1,
which provides a number of bug fixes and enhancements over the previous version.
(BZ#1165842)

The user space library infinipath-psm has been upgraded to upstream version 3.3,
which provides a number of bug fixes and enhancements over the previous version.
(BZ#1138643)

This update also fixes the following bugs:

• When shutting down a system with InfiniBand (IB) modules loaded, the system

displayed a "Failed to unload ib_addr" error message during the shutdown
process. This update corrects the order in which IB modules are unloaded, and
the error message no longer appears. (BZ#1159331)

• Prior to this update, shutting down the nfs-rdma service failed and printed

the following message in the console:

Please stop the nfs-rdma service before stopping the rdma service.

The order of nfs-rdma shutdown steps has been corrected, and nfs-rdma now stops
correctly. (BZ#1151159)

• Previously, the mstvpd program failed with a segmentation fault when used.

With this update, the underlying code has been fixed, and the problem no longer
occurs. (BZ#1006988)

In addition, this update adds this enhancement:

• The ifup-ib script artificially limited the maximum transmission unit (MTU)

amount of IP over InfiniBand (IPoIB) devices running in datagram mode to 2044.
This has been fixed, and the new limit now depends on the underlying MTU of the
InfiniBand fabric. As a result, IPoIB devices can now have MTU up to 4092 if the
InfiniBand fabric MTU is also 4092. (BZ#1186498)

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