[libvirt] [PATCH 0/3] Fix examples/ under mingw
by Eric Blake 09 Jan '19

09 Jan '19

My recent patch to make all of the examples work independently of gnulib worked fine on Linux, but failed on mingw: https://travis-ci.org/libvirt/libvirt/jobs/476898635 The whole point of gnulib is to work around portability pitfalls so we don't have to bend over backwards thinking about it in our code; and it would be possible to fix this bug by linking the problematic example binaries against gnulib after all. But since the examples are still small and self-contained enough that using manual workarounds wasn't too daunting, that's the approach I took here. I'm pushing this series as a build-breaker fix in a couple of hours, or sooner if I get a review.

[libvirt] [PATCH] qemu: Use ULL instead of uint64_t for RDMA GID event
by Michal Privoznik 09 Jan '19

09 Jan '19

In the previous commit we are using uint64_t for storing subnet prefix and interface id that qemu reports in RDMA_GID_STATUS_CHANGED event. We also report them in some debug messages. This poses a problem because uint64_t can be UL or ULL depending on the host architecture and hence we wouldn't know which format to use. Switch to ULL which is big enough and doesn't suffer from the issue.

[libvirt] [PATCH v3 RESEND] qemu: Process RDMA GID state change event
by Yuval Shaia 09 Jan '19

09 Jan '19

This event is emitted on the monitor when a GID table in pvrdma device is modified and the change needs to be propagate to the backend RDMA device's GID table. The control over the RDMA device's GID table is done by updating the device's Ethernet function addresses. Usually the first GID entry is determine by the MAC address, the second by the first IPv6 address and the third by the IPv4 address. Other entries can be added by adding more IP addresses. The opposite is the same, i.e. whenever an address is removed, the corresponding GID entry is removed. The process is done by the network and RDMA stacks. Whenever an address is added the ib_core driver is notified and calls the device driver's add_gid function which in turn update the device. To support this in pvrdma device we need to hook into the create_bind and destroy_bind HW commands triggered by pvrdma driver in guest. Whenever a changed is made to the pvrdma device's GID table a special QMP messages is sent to be processed by libvirt to update the address of the backend Ethernet device.

I noticed from IRC that Travis has been failing builds since our Jan 1 update of gnulib. I'm not sure what changed in the gnulib files to trip up clang, and I'm not really set up to test that this fixes the problem seen by Travis (it works locally for me using gcc - but gcc wasn't seeing the failure), but the ideas in the patch make sense. So, unless there is an easy way to make Travis run on candidate patches, I'll wait for a review rather than pushing this as a build-breaker.
