Title:
PCI RoCe IB perftest Aborted (core dumped)

Status in perftest package in Ubuntu:
Fix Released
Status in perftest source package in Xenial:
Confirmed
Status in perftest source package in Yakkety:
Confirmed
Bug description:
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 ...
