[Bug 302230] [NEW] vsock module does not load

[Adar Dembo]

Public bug reported:

Binary package hint: open-vm-source

The vsock module depends on the vmci module, and in recent kernels
(including those of Intrepid and Jaunty) such dependencies are validated
at build-time by the modpost utility. If one module is built without
seeing the Modpost.symvers of the other, the resulting module cannot be
loaded by the kernel. In vsock's case, the failure looks like this:

[  390.548696] vsock: no symbol version for VMCIMemcpyToQueueV
[  390.548696] vsock: Unknown symbol VMCIMemcpyToQueueV

This was fixed in open-vm-tools upstream as part of the 2008.11.18
release, and as such, is fixed in Jaunty. However, Intrepid's vsock
module is affected and as such cannot load in Intrepid.

I've created and attached a patch that fixes this, against the open-vm-
source package version 2008.08.08-109361-1ubuntu2.1. It's essentially a
backport of the patch found upstream.
