[Test Case] * To have IPoIB devices (2 if possible) * Try to acquire IP using either DHCPv4 or DHCPv6 [Regression Potential] * DHCP for InfiniBand was not working * Based on already implemented code (Fedora) * Mellanox has tested it [Other Info] Original BUG description: Release: Ubuntu 14.04.1 LTS Version: 4.2.4-7ubuntu12 The current DHCP package in Ubuntu can't handle IPoIB clients. For IB, Mellanox uses IPoIB, which is “Eth emulator” for the control path. DHCP is not working in this mode without a patch for DHCP server. ISC-DHCP-SERVER Missing GPXE patch. After applying GPXE patch only we faced the following problems: After apply 1. dhcp ipoib, does not write in the log on which interface the dhcp work upon when starting the dhcp server using “/etc/init.d/isc-dhcp-server start” we don’t see the line that tells on which interfaces the dhcpd is listening on the /var/log/syslog when running it with “dhcpd –d” command – we do see it. 2. dhcp ipoib ipv6, it did not provide ip6 when we start 2 ib interfaces in a parallel using the following setup: HOST_A: acting as a dhcp server, listening on one of its ipoib (ib0) interfaces. HOST_B: running dhcp clients on two ipoib interfaces (ib1, ib2) ib1 and ib2 are two ports onf the same HCA both interfaces are configured in /etc/interfaces such as: auto ib1 iface ib1 inet6 dhcp both interfaces are configured in /etc/dhcp/dhclient.conf with their dhcp-client-identifier Ib0@HOST_A, Ib1@HOST_B and Ib2@HOST_B are connected to an infiniband switch. We are running on the client (HOST_B) the following: $ ifup ib1 -> ib1 get configured as expected but then when we run on the other interface: $ ifup ib2 -> ib2 get configured, but ib1 is losing its configuration To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/isc-dhcp/+bug/1401141/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
