Debian-only, Ubuntu-only, SLES-only, and pre-Enterprise Linux 8 public drops are not listed because this script targets RPM source packages for Enterprise Linux 8 or 9.

Usage:

Just run patch-mlnxofed.sh on a machine where MLNX OFED is already installed, and you should be fine.

The script will execute dnf to install the new packages, but it's up to you to install it or not. The resulting RPMs will be available by default on PATCHED-MLNX-OFED directory inside $HOME

Verification

You can verify expected source markers and patched output lines against upstream rdma-core source RPMs with:

tests/verify-releases.sh 25.01-0.6.0.0 24.10-4.1.4.0 24.04-0.6.5.0 23.04-0.5.3.3 5.8-7.0.6.1 5.3-1.0.5.0 4.7-3.2.9.0

You can check for new upstream Enterprise Linux MLNX OFED releases with:

tests/check-upstream-releases.sh

The scheduled GitHub Actions workflow runs the same check weekly. If NVIDIA publishes a new RPM-backed Enterprise Linux release, it opens or updates one upstream-update issue.
