ibdev2netdev now skips InfiniBand net device bonding interfaces, and always matches InfiniBand devices to the underlying InfiniBand net device interfaces.

Keywords: ibdev2netdev Bonding

Discovered in Release: 5.0-1.0.0.0

Fixed in Release: 5.4-3.1.0.0

2687643

Fixed in Release: 5.4-3.1.0.0

2691081

Description: Removed metadata from the rpm package mlnx-ofa_kernel where it claimed to Provide an older version of rdma-core. This made sense in older versions where we needed to avoid installing rdma-core. But does not make sense anymore. And caused problems to some users installing rdma-core-devel through meta-packages.

Keywords: Installation

Discovered in Release: 5.4-1.0.3.0

Fixed in Release: 5.4-3.1.0.0

2727062

Description: Removed manual build-time file list generation in mlnx-tools. Only keep it for python-installed files. And avoid guessing the version of python we use and the directory to which we install.

Keywords: Installation

Discovered in Release: 5.4-1.0.3.0

Fixed in Release: 5.4-3.1.0.0

2708220

Description: Removed useless build-time editing of uninstall.sh in ofed-scripts that caused the build to fail (in the case of --add-kernel-support) in some rare cases.

Keywords: Installation

Discovered in Release: 5.4-1.0.3.0

Fixed in Release: 5.4-3.1.0.0

2699662

Description: MLNX_OFED build scripts fixed to also build hcoll with CUDA support on RHEL8 x86_64 platforms.

Keywords: Installation, CUDA

Discovered in Release: 5.4-1.0.3.0

Fixed in Release: 5.4-3.1.0.0

2686877

Keywords: mtu, synchronize_net

Discovered in Release: 5.4-1.0.3.0

Fixed in Release: 5.4-3.1.0.0

2748328

Description: When trying to upgrade a kmp package, it conflicts and needs user help to choose whether to replace it or not. The fix avoids conflicts from /usr/lib/rpm/kernel-module-subpackage script which was changed in the builder. Building the packages with kmp enabled on the other image will cause the issue to reproduce.

Keywords: Upgrade, kmp Package, Installation

Discovered in Release: 5.4-1.0.3.0

Fixed in Release: 5.4-3.1.0.0

2707023

Description: On Ubuntu and Debian systems for openvswitch-switch (in case installing using e.g. --ovs-dpdk or --with-openvswitch), the installer misses a run-time dependency of libpcap0.8.

Keywords: Installation, Ubuntu, Debian

Discovered in Release: 5.4-1.0.3.0

Fixed in Release: 5.4-3.1.0.0
