This is an adjustment to the fix for https://bugzilla.redhat.com/show_bug.cgi?id=889319 to account for two bonehead mistakes I made. commit ac2797cf2af2fd0e64c58a48409a8175d24d6f86 attempted to fix a problem with netlink in newer kernels requiring an extra attribute with a filter flag set in order to receive an IFLA_VFINFO_LIST from netlink. Unfortunately, the #ifdef that protected against compiling it in on systems without the new flag went a bit too far, assuring that the new code would *never* be compiled, and even if it had, the code was incorrect. The first problem was that, while some IFLA_* enum values are also their existence at compile time, IFLA_EXT_MASK *isn't* #defined, so checking to see if it's #defined is not a valid method of determining whether or not to add the attribute. Fortunately, the flag that is being set (RTEXT_FILTER_VF) *is* #defined, and it is never present if IFLA_EXT_MASK isn't, so it's sufficient to just check for that flag. And to top it off, due to the code not actually compiling when I thought it did, I didn't realize that I'd been given the wrong arglist to nla_put() - you can't just send a const value to nla_put, you have to send it a pointer to memory containing what you want to add to the message, along with the length of that memory. This time I've actually sent the patch over to the other machine that's experiencing the problem, applied it to the branch being used (0.10.2) and verified that it works properly, i.e. it does fix the problem it's supposed to fix. :-/ (cherry picked from commit 7c36650699f33e54361720f824efdf164bc6e65d)
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
