[libvirt] [PATCH] libvirtd: fix potential deadlock when reloading
by Jim Fehlig
It is possible to deadlock libvirtd when concurrently starting a domain
and restarting the daemon. Threads involved in the deadlock are

Reloading of the nwfilter driver is stuck waiting for a write lock, which
already has a reader (from qemuDomainCreateXML) in the critical section.
Since the reload occurs in the context of the main event loop thread,
libvirtd becomes deadlocked. The deadlock can be avoided by offloading
the reload work to a thread.

[libvirt] [PATCH] Update to latest gnulib
by Daniel P. Berrangé
GnuLib has now fixed the incompatibility with latest GLibC
that was affecting builds on Fedora rawhide. We can thus
update and drop our local workaround.

Pushed to git since we don't review trivial gnulib updates.

[libvirt] [PATCH go-xml] fix type tag for rdp and destkop graphics devices
by Ryan Goodfellow
The current behavior is to generate a type="vnc" tag in the <graphics>
element generated from either a DomainGrapicRDP or DomainGraphicDesktop.
The correct tags should be type="rdp" and type="desktop" respectively.
This commit emits the correct tags and adds a test for correct graphics
device tagging.

[libvirt] [PATCH] util, remote: Fixing the sending of stream when length is defined.
by Julio Faracco
When a length of a file is defined, the responsible thread to send
stream is finishing inappropriately. It is happening because there is
wrong conditional which compares an offset with the length and because
of that the code throws ENOSPC error.
To test it:

[libvirt] [PATCH 0/3] Update the virsh pool define/create for vHBA/NPIV
by John Ferlan
Looks like when adding support in commit 78be2e8b (and the 3 just
before it), I neglected to update the virsh command allow command
line usage of the fields. This series updates virsh in order to
allow adding the fields (as ugly as they are) to make it easier
to define/create the pool with the fields.
John Ferlan (3):
tools: Add the wwnn/wwpn to the man page for storage pool fields
tools: Update the help description of the adapter-parent field
tools: Add support for additional adapter parent options

This patch conflicts with Michal's persistent reservations series. I'll
need the code in the place this patch places it later so I'm sending
this to avoid having to move this again very soon.

[libvirt] libvirt-snmp status
by Michael Corcoran
Hi All,
I'd like to enquire about the status of libvirt-snmp. It hasn't had any
commits for a couple of years and no longer compiles against recent
versions of net-snmp. As I understand it, upstream net-snmp deprecated
and then removed the C type "U64" as it conflicts with Perl.
Fortunately this is the only issue and the patch required to get
libvirt-snmp building again simply replaces the C type "U64" with the
type "struct counter64" in a few places. I tried to submit a patch but
was unable to configure authentication/encryption correctly for git
send-email and I'm unwilling to spend more time on it. Is there any way
to accept patches directly from Github (or anywhere else I can push a
commit)?
My second enquiry relates to the org OID used in the LIBVIRT-MIB. It
currently uses a (presumably) placeholder of 12345. I check the OID
register[1] and found an entry for libvirt (see end of email). I am
guessing that registration didn't go through until after libvirt-snmp
maintenance stopped. I'd like to submit a patch to replace the
placeholder with this org id also.
BR,
Michael Corcoran

[libvirt] [PATCH v7 00/11] qemu: Validate PCI controller options
by Andrea Bolognani
Applies cleanly on top of b932ed69f6664f42e211bdde84c8ab04e1f19033.
Patches 2/11 and 4/11 are the only ones missing R-bs, everything
else hasn't been significantly altered since [v5].
Changes from [v6]:
* don't special-case the default PHB when checking capabilities.
Changes from [v5]:
* patch 1 has been pushed;
* add virReportController*() functions to cut down on redundant
error reporting, as suggested by laine;
* report index and modelName along with model in error messages.
Changes from [v4]:
* patch 1/12 is new;
* use virReportEnumRangeError(), as suggested by laine.
Changes from [v3]:
* don't introduce new test cases that won't be able to provide
full test coverage anyway, as suggested by laine.
Changes from [v2]:
* replace the old implementation bit by bit using a clever trick
suggested by pkrempa;
* don't move QEMU capability validation;
* add a default: label to all switch statements as recommended
by danpb.
Changes from [v1]:
* error out instead of silently accept invalid options;
* shave quite a lot of yaks.
