[libvirt] [PATCH] qemu: remove memset params array to zero in qemuDomainGetPercpuStats
by Gao feng 16 Jan '14

16 Jan '14

the array params is allocated by VIR_ALLOC_N in cmdCPUStats. it had been set to zero. No need to reset it to zero again, and this reset here is incorrect too, nparams * ncpus is the array length not the size of params array.

[libvirt] [PATCH 0/4] CVE-2014-0028: domain events vs. ACL filtering
by Eric Blake 15 Jan '14

15 Jan '14

I have pushed the following series to the master branch, as well as the the backport of patch 4 to all branches impacted by the CVE (v1.1.0 onwards). Basically, when ACLs permit fine-grained control of what domains a user can manage, a user that was denied domain:getattr for a particular domain, or denied connect:search_domains in general, could use the event registration API to gain access to domains that should have been hidden from that user. The patch was reviewed offlist during the time when the vulnerability was under embargo. In the process of fixing this, I made quite a few improvements to the underlying mechanisms for events. Among other things, I want to switch libvirt over to using server-side filtering rather than the current implementation of client-side filtering, for increased efficiency in the case where a hypervisor hosts many guests but the client only cares about events on a small subset of those guests. The existing RPC calls for domain events did not allow this, but the brand new network events had not yet had their RPC baked with a formal release. At one point, I had tried making the use of connect:search_networks conditional on whether a non-NULL network had been requested, which requires server-side filtering. The final incarnation of the CVE fix no longer bypasses connect:search_networks for a NULL network, so the first three patches are now technically unrelated to the CVE fix; but as the work is already done and reviewed and as it is easier to avoid bloat in the RPC protocol by getting it right from the beginning, I still pushed those patches to the master branch. NOTE: if you were testing network events with libvirt.git or with the 1.2.1 release candidates, you must ensure that you match your client's use of libvirt.so with the libvirtd - early users of network events are unable to communicate with the RPC wire representation that will actually be in 1.2.1 as a result of this series. I will also be posting a followup series, for application after 1.2.1 is released, which adds server-side filtering of domain events, as the counterpart of the network event filtering added in this series. There, we already have existing RPC code baked into releases, so there is no longer a rush to get the patches in before a release freezes a mistake.

[libvirt] [PATCH 0/5] server-side filtering of domain events
by Eric Blake 15 Jan '14

15 Jan '14

This work was originally done with the thought that the fix for CVE-2014-0028 would require server-side filtering to make the check of connect:search_domains conditional on whether the user passed NULL or a domain when registering for an event. The final version of the CVE fix no longer needs the conditional behavior, so there is no longer a rush to get this in to 1.2.1; but for 1.2.2, the code changes offer a nice efficiency gain for the use case of libvirtd managing lots of domains while a client only cares about events from a small subset of domains. While this will not be in 1.2.1 proper, I also tested that the entire series can be backported without breaking the .so versioning, if any downstream distro wants to include the efficiency gain as part of their value added maintenance of an older version.

[libvirt] [PATCH] BSD: implement nodeGetCPUStats
by Roman Bogorodskiy 15 Jan '14

15 Jan '14

I had doubts how to implement that. Looks like the current implementation is tied to Linux CPU metrics: user nice system idle iowait That list is hardcoded into virsh-host.c. FreeBSD has a slightly different set of metrics: user nice system intr idle I.e. it's interrupt time instead of i/o time. I decided to go without virsh-host.c modification and used VIR_NODE_CPU_STATS_UTILIZATION. If you know better way of doing that, I'm open for suggestions.

[libvirt] [PATCHv2] tests: be more explicit on qcow2 versions in virstoragetest
by Eric Blake 15 Jan '14

15 Jan '14

While working on v1.0.5-maint (the branch in use on Fedora 19) with the host at Fedora 20, I got a failure in virstoragetest. I traced it to the fact that we were using qemu-img to create a qcow2 file, but qemu-img changed from creating v2 files by default in F19 to creating v3 files in F20. Rather than leaving it up to qemu-img, it is better to write the test to force testing of BOTH file formats (better code coverage and all). This patch alone does not fix all the failures in v1.0.5-maint; for that, we must decide to either teach the older branch to understand v3 files, or to reject them outright as unsupported. But for upstream, making the test less dependent on changing qemu-img defaults is always a good thing. * tests/virstoragetest.c (testPrepImages): Simplify creation of raw file; check if qemu supports compat and if so use it.
