Updated rdma packages that fix several bugs and add various enhancements are now available for Red Hat Enterprise Linux 6.
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)
- 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.
- 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.
- 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.
- 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.
Users of rdma are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.
