IPoIB: Clear ipoib_neigh.dgid in ipoib_neigh_alloc()

IPoIB can miss a change in destination GID under some conditions. The problem is caused when ipoib_neigh->dgid contains a stale address. The fix is to set ipoib_neigh->dgid to zero in ipoib_neigh_alloc().

This can happen when a system using bonding on its IPoIB interfaces has switched its active interface from interface A to B and back to A. The system that fails over will not correctly processes the 2nd address change, as described below.

When an address has changed neighbor->ha is updated with the new address. Each neighbor has an associated ipoib_neigh. ipoib_neigh->dgid also holds a copy of the remote node's hardware address. When an address changes neighbor->ha is updated by the network layer (arp code) with the new address. IPoIB detects this change in ipoib_start_xmit() by comparing neighbor->ha with ipoib_neigh->dgid. The bug is that ipoib_neigh->dgid may already contain the new address (A) thus the change from B to A is missed by ipoib. Here is the sequence of events:

ipoib_neigh->dgid = A and neighbor->ha = A

The address is switched to B (the first switch)

neighbor->ha = B

The change is seen in ipoib_start_xmit() -- neighbor->ha != ipoib_neigh->dgid so ipoib_neigh is released, and a new one is allocated.

The allocator may return the same chunk of memory that was just released, therefore ipoib_neigh->dgid still contains A at this point.

ipoib_neigh->dgid should be updated in neigh_add_path(), but if the following conditions are true dgid is not updated:

1) __path_find() returns a path
2) path->ah is NULL

The remote system now switches from address B to A, neighbor->ha is updated to A.

Now we have again : ipoib_neigh->dgid = A and neighbor->ha = A Since the addresses are the same ipoib won't process the change in address. Fix this by zeroing out the dgid field when allocating a new struct ipoib_neigh.

I've tried to download RC6, but openfabrics.org seems to be down. Will try again later today...

You can download it using scp if you have a user on the OFA server:
scp <username>@69.55.231.180:/var/www/openfabrics.org/downloads/OFED/ofed-1.5/OFED-1.5-rc6.tgz .

There is a problem with primary network interface of the OFA server (eth0 69.55.231.195). Other three virtual interfaces work well (eth0:1 69.55.231.178, eth0:2 69.55.231.179, eth0:3 69.55.231.180). So, bugzilla, wiki and svn web pages are working.

Jeff,
Can you check this issue?

Regards,
Vladimir
