[libvirt] [PATCH] Don't chown qemu saved image back to root after save if dynamic_ownership=0
by Laine Stump
When dynamic_ownership=0, saved images must be owned by the same uid
as is used to run the qemu process, otherwise restore won't work. To
accomplish this, qemuSecurityDACRestoreSavedStateLabel() needs to
simply return when it's called.
This fix is in response to:
https://bugzilla.redhat.com/show_bug.cgi?id=661720
---
Note that this still leaves open the issue discovered in this bug - if
the saved image file already exists when it is "created" for the new
save, whatever mode it has will be maintained, rather than forcing
0600. It would be simple to force the mode to 0600 (just add a flag to
virFileOperation(), but I'm not sure if it would be safe to do so
right now without a *lot* of testing (I'm concerned about possible
scenarios where the chmod() that's done when the FORCE_PERMISSIONS
flag is set might fail, making a previously working case fail). Any
opinions on that? (At any rate, it should be done in a separate patch
if we decide to do it).

[libvirt] [PATCH] wrong if-condition in bridge_driver.c, networkBuildDnsmasqArgv, dhcp host definition
by Kay Schubert
I added a host definition to a network definition:

<name>Lokal</name>

<host mac='23:74:00:03:42:02' name='somevm' ip='192.168.180.10' />
</dhcp>
</ip>
</network>
But due to the wrong if-statement the argument --dhcp-hostsfile doesn't get
added to the dnsmasq command. The patch below fixes it for me.

[libvirt] [PATCH] Device reattach: Check if device is assigned to guest before reattaching
by Yufang Zhang
Reattaching pci device back to host without destroying guest or detaching
device from guest would cause host to crash. This patch adds a check before
doing device reattach. If the device is being assigned to guest, libvirt
refuses to reattach device to host. Note that the patch only works for Xen,
for it just checks xenstore to get pci device information.

[libvirt] commandtest fails when executed with preloaded libraries
by Diego Elio Pettenò
In Gentoo we sandbox software installation with a software called
sandbox, which basically is a preloaded library that wraps around a
number of file access functions.
This method seems to break commandtest because the environment now has a
LD_PRELOAD variable in it, which is not accounted for in the
pre-generated log files.
Any idea how I should go about to solve this beside adding LD_PRELOAD to
the log files themselves for Gentoo?

[libvirt] [00/15] Re-factoring XDR RPC code v2
by Daniel P. Berrange
A followup to
http://www.redhat.com/archives/libvir-list/2010-December/msg00051.html
Since that time
- The SASL/TLS I/O code has been integrated into the virNetSocket
class directly to remove duplication between client&servers
- libvirtd has been converted to use the new APIs
- Error handling has been sanitized across libvirtd to use the
normal virReportError APIs
- A couple of test cases have been written
- Many locking, ref counting & ramdom crash bugs fixed
- Some basic interoperability testing against previous code
This is still not quite functionally complete, so not ready to
apply. The missing pieces are
- Make the client side streams code work again
- Re-integrate DTrace probes in libvirtd

[libvirt] [PATCH] schema: tighten <serial><protocol type=...> relaxNG
by Eric Blake
virDomainChrTcpProtocol only accepts particular <protocol type=...>
values, but we weren't enforcing that in the RelaxNG. The valid
types are also already documented in docs/formatdomain.html.in.
* docs/schemas/domain.rng (qemucdevSrcDef): Restrict list of
supported <protocol type=> values.
---
Noticed this while working on <smartcard>, but it is an independent
issue worth fixing whenever it gets an ack.

Re: [libvirt] adding smartcard support to libvirt
by Eric Blake
[adding the public list for feedback on new XML. Background: Alon is
working on adding some new command line arguments to qemu to make it
possible to share smartcard access between a host and its virtual
guests; while this is not upstream yet, libvirt should be prepared to
handle the new command line options]

Just to restate (to make sure I'm understanding you correctly),
smartcard support in qemu requires that you enable two things: the
usb-ccid device, and your choice of the ccid-card-emulated device or the
ccid-card-passthru device. The ccid-card-emulated device operates in
two modes, and the ccid-card-passthru device uses a protocol to talk
through a required associated chardev (where the other end of the
chardev can operate in two modes, but that's outside of what the guest
can see; and where two particular chardevs make the most sense).

Picking the right mode names is probably the hardest part of writing new
XML in a way that can be reused across other hypervisor technologies if
similar approaches are adopted there, as well as allowing reasonable XML
additions in the future, which is why I'm opening the feedback to make
sure it all looks good.

Then <source> isn't quite the right terminology for this. If we ever do
come up with a future qemu device that can replace usb-ccid while still
providing everything needed for the ccid-card-emulated device to work,
then we can augment the XML at that point for choosing how to replace
the usb-ccid device, but I don't think we need to tie it to <source> for
the current proposal.
So, this mode can be simplified. In other words, requesting mode='host'
implies turning on anything in the hypervisor necessary to let the
hypervisor use NSS access to the host's smartcard support (in qemu's
case, turning on both the usb-ccid device and the ccid-card-emulated
device with no arguments). Therefore, mode='host' wouldn't need any
sub-elements for now.
<domain...>
<devices>
<smartcard mode='host'/>
</devices>
</domain>

So, here's the updated proposal (again, dropping a <source> element, and
picking a better mode name):
<domain...>
<devices>
<smartcard mode='host-certificates'>
<certificate id='1' path='cert1'/>
<certificate id='2' path='cert2'/>
<certificate id='3' path='cert3'/>
</smartcard>
</devices>
</domain>

So the key point here is that use of the ccid-card-passthru device
requires a chardev=xyz argument that maps to another existing -chardev
device. And given that the chardev device in use is essential to the
smartcard support, I'm proposing that the <smartcard> element require
the paired chardev device as a sub-element, rather than as a sibling
element.
Right now, the XML for <devices> allows the following <serial> types:
dev, file, pipe, unix, tcp, udp, null, stdio, vc, pty
so there's no notion of a type='smartcard'. It looks more like the new
serial type is 'spicevmc'. And back to my idea of omitting mention of
usb-ccid in the XML, and refactoring things to avoid dupicate use of
strings (to make it a bit more obvious which XML aspects impact which
command-line aspects), that leaves us with:
<domain...>
<devices>
<smartcard mode='passthrough' name='xyz'>
<serial type='spicevmc'/>
</smartcard>
</devices>
</domain>
maps to qemu -chardev spicevmc,id=smartcard,name=xyz -usb -device
usb-ccid -device ccid-card-passthru,chardev=xyz
Am I correct that a spicevmc -chardev has to use a fixed id=smartcard
but an arbitrary name, and that ccid-card-passthru has to have a
chardev=name that maps to the same name= used for a -chardev? Or is it
that ccid-card-passthru has to have a chardev=name that maps to the same
name as a -chardev id=name?
And, given the goal that <smartcard mode='passthrough'> then has a child
element that describes the passthrough device, it also means that I
would be adding support for a top-level spicevmc chardev device,
unrelated to smartcards; would this need any additional XML parameters?
<domain...>
<devices>
<serial type='spicevmc'>
<!-- anything else needed for a top-level spicevmc chardev? -->
</serial>
</devices>
</domain>

My thoughts were that the name attribute of the <smartcard> element
becomes the string that get reused twice in the qemu command line (once
in the -chardev name, once I figure out whether that is by the id= or
the name= field, and once in the -ccid-card-passthru chardev= field).
This one is a bit easier, since top-level <serial type='tcp'> already
exists, so I think this one remains:
<domain...>
<devices>
<smartcard mode='passthrough' name='ccid'>
<serial type='tcp'>
<source host='0.0.0.0' port='2001'/>
<protocol type='tcp'/>
</serial>
</smartcard>
</devices>

In summary, this is my proposal for the new XML; feedback welcome to
correct anything:
<devices> modifies one existing sub-element (<serial> learns a new
type='spicevmc' to match qemu's new spicevmc chardev), and adds a new
sub-element <smartcard>. The new <smartcard> element has a required
mode attribute, that takes on one of three strings:
<smartcard mode='host'/>
no other attributes, no sub-elements. Implies that the hypervisor
exposes whatever devices necessary to the guest to see a smartcard, and
feeds the smartcard implementation by communicating natively with the
host smartcard for all needed information (maps to qemu -usb -device
usb-ccid -device ccid-card-emulated)
<smartcard mode='host-certificates'>
<certificate id='1' path='cert1'/>
<certificate id='2' path='cert2'/>
<certificate id='3' path='cert3'/>
</smartcard>
no other attributes, but requires three <certificate> sub-elements.
Implies that the hypervisor exposes whatever devices necessary to the
guest to see a smartcard, and that it feeds the smartcard implementation
with three certificate files living in the host rather than trying to
talk to a host smartcard (maps to qemu -usb -device usb-ccid -device
ccid-card-emulated,backend=certificates,cert1=cert1,cert2=cert2,cert3=cert3)
<smartcard mode='passthrough' name='xyz'>
<serial .../>
</smartcard>
name attribute is optional but recommended (assuming libvirt can create
a unique name if none is provided). <serial> sub-element is required,
with the same form as a normal <serial> sub-element of <devices>, but
the common uses will be <serial type='tcp'> (existing) or <serial
type='spicevmc'> (new). Implies that the hypervisor exposes whatever
devices necessary to the guest to see a smartcard, and that it feeds the
smartcard implementation via the associated char device (maps to qemu
-chardev ...,name=xyz -usb -device usb-ccid -device
ccid-card-passthru,chardev-xyz)

[libvirt] [PATCH] qemu-monitor-command: hide the low level protocol
by Lai Jiangshan
When qmp protocol is available, the libvirt will use this protocol
to communicates with qemu. And when we use "virsh qemu-monitor-command",
we need:
virsh qemu-monitor-command dom '{ "execute": "eject", \
"arguments": { "device": "ide1-cd0" } }'
But virsh is typical a human command line interface, it is not comfortable
that a human user has to construct such commands. This patch makes
human user can use
virsh qemu-monitor-command dom 'eject ide1-cd0'
in any time(qmp protocol is available or not).
The result string is also converted to the same as non-qmp-protocol version.
The user do not need to concern about the low level protocol now.

[libvirt] [PATCH] bridge_driver: use conffile for dnsmasq if it exists
by Paweł Krześniak
By default dnsmasq is spawned with option --conf-file="" which disables
reading of global configuration file -- this is fine for most situations.
This patch adds possibility to run customized DNS/DHCP environment, by
spawning dnsmasq with alternative configuration file if such file exists.
This allows you to set any parameter described in dnsmasq(8).
Configuration file is expected to be located in file named
"<network_name>-dnsmasq.conf" in DNSMASQ_STATE_DIR directory.
If configuration file doesn't exists dnsmasq is spawned as before.
Patch should be applied after my earlier one.
