Date: Mon, 20 Aug 2007 18:34:12 +0300 From: Moni Shoua <monis@...taire.com> To: rdreier@...co.com, davem@...emloft.net, fubar@...ibm.com CC: netdev@...r.kernel.org, general@...ts.openfabrics.org Subject: [PATCH V4 0/10] net/bonding: ADD IPoIB support for the bonding driver This patch series is the fourth version (see below link to V3) of the suggested changes to the bonding driver so it would be able to support non ARPHRD_ETHER netdevices for its High-Availability (active-backup) mode. The motivation is to enable the bonding driver on its HA mode to work with the IP over Infiniband (IPoIB) driver. With these patches I was able to enslave IPoIB netdevices and run TCP, UDP, IP (UDP) Multicast and ICMP traffic with fail-over and fail-back working fine. The working environment was the net-2.6 git. More over, as IPoIB is also the IB ARP provider for the RDMA CM driver which is used by native IB ULPs whose addressing scheme is based on IP (e.g. iSER, SDP, Lustre, NFSoRDMA, RDS), bonding support for IPoIB devices **enables** HA for these ULPs. This holds as when the ULP is informed by the IB HW on the failure of the current IB connection, it just need to reconnect, where the bonding device will now issue the IB ARP over the active IPoIB slave. This series also includes patches to the IPoIB driver that fix some fix some neighboring related issues. Major changes from the previous version: 1) Addressing the issue of safety when unloading the IPoIB module before the bonding module 2) style changes Links to earlier discussion: 1. A discussion in netdev about bonding support for IPoIB. http://lists.openwall.net/netdev/2006/11/30/46 2. A discussion in openfabrics regarding changes in the IPoIB that enable using it as a slave for bonding. http://lists.openfabrics.org/pipermail/general/2007-July/038914.html - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
