** Description changed: + SRU: + ==== + + [Impact] + + * the perftest tools (ib_*) incl. in the perftest package cannot be used at all, they all always core dump on all platforms + * a backport is required for getting again a working perftest package / tool set + * the fix was officially provided by Mellanox and fixes the version comparison that was broken before (partly using int, partly string compares) + + [Test Case] + + * the bug can easily be reproduced on two systems both with RoCE cards installed + and by starting a perftest run like this: + on one machine as 'server': sudo ./ib_read_bw -d mlx4_0 -a + and on a second machine as 'client', pointing to the servers IP address: sudo ./ib_read_bw <server IP> -d mlx4_0 + + detailed instructions how to reproduce the bug + + * install the perftest package including all dependencies + * configure the RoCE devices as network devices using a private network range in /etc/network/interfaces like this + # The 1st RoCE interface configuration + auto enP1p0s0 + iface enP1p0s0 inet static + address 192.168.1.141 + netmask 255.255.255.0 + network 192.168.1.0 + broadcast 192.168.1.255 + * test if the network is okay, with ping (or rping, udaddy rdma_client/rdma_server) + * and run the Test Case above + + [Regression Potential] + + * the regression is low due to the fact that the current tools that are part of the perftest package just segfault and are unusable + * the target for this patched perftest package is Zesty (and higher), because only Zesty has the depending packages in an up-to-date version + + * people may ask to SRU that to Xenial as well, but that would require + the update of several other packages ... + + --------%<----------------%<----------------%<----------------%<-------- + == Comment: #0 -
