Updated libibverbs-rocee and libmlx4-rocee packages that fix one bug are now available for Red Hat Enterprise Linux High Performance Network.
The libibverbs-rocee packages provide a library to enable userspace processes to use RDMA over Converged Ethernet (RoCE) "verbs" acording to the InfiniBand Architecture Specification and the RoCE Protocol Verbs Specification. The libmlx4-rocee packages provide a device-specific driver for Mellanox ConnectX InfiniBand host channel adapters (HCAs) for the libibverbs-rocee library.
Prior to this update, running modprobe could, under certain circumstances, cause an infinite loop. As a consequence, the system ran out of processes and required a restart to recover. This update modifies the underlying code so that an incorrect configuration of options in the /etc/modprobe.d/libmlx4.conf file no longer requires to restart the system.
This package is a dependency of the RDMA package and both packages have to be updated together.
All users who require RDMA are advised to upgrade to these updated packages which fix this bug.
