This resolves the issue that prompted the filing of
https://bugzilla.redhat.com/show_bug.cgi?id=928638
(although the request there is for something much larger and more
general than this patch).
commit f3868259ca disabled the
forwarding to upstream DNS servers of unresolved DNS requests for
names that had no domain, but were just simple host names (no "."
character anywhere in the name). While this behavior is frowned upon
by DNS root servers (that's why it was changed in libvirt), it is
convenient in some cases, and since dnsmasq can be configured to allow
it, it must not be strictly forbidden.
This patch restores the old behavior, but since it is usually
undesirable, restoring it requires specification of a new option in
the network config. Adding the attribute "forwardPlainNames='yes'" to
the <dns> elemnt does the trick - when that attribute is added to a
network config, any simple hostnames that can't be resolved by the
network's dnsmasq instance will be forwarded to the DNS servers listed
in the host's /etc/resolv.conf for an attempt at resolution (just as
any FQDN would be forwarded).
When that attribute *isn't* specified, unresolved simple names will
*not* be forwarded to the upstream DNS server - this is the default
behavior.
The description for <permissions> was copied from the storage volume
section to the storage pool section, but the semantics are different:
1. Currently only the "dir", "fs" and "netfs" storage pools use it.
2. They use it only to build the final directory.
3. A default for the storage volumes can't be set.

The gnulib testsuite is relatively stable - the only times it is
likely to have a test change from pass to fail is on a gnulib
submodule update or a major system change (such as moving from
Fedora 18 to 19, or other large change to libc). While it is an
important test for end users on arbitrary machines (to make sure
that the portability glue works for their machine), it mostly
wastes time for development testing (as most developers aren't
making any of the major changes that would cause gnulib tests
to alter behavior). Thus, it pays to make the tests optional
at configure time, defaulting to off for development, on for
tarballs, with autobuilders requesting it to be on. It also
helps to allow a make-time override, via VIR_TEST_EXPENSIVE=[01]
(much the way automake sets up V=[01] for overriding the configure
time default of how verbose to be).
Automake has some pretty hard-coded magic with regards to the
TESTS variable; I had quite a job figuring out how to keep
'make distcheck' passing regardless of the configure option
setting in use, while still disabling the tests at runtime
when I did not configure them on and did not use the override
variable. Thankfully, we require GNU make, which lets me
hide some information from Automake's magic handling of TESTS.

This adds two new pages to the website, acl.html describing
the general access control framework and permissions models,
and aclpolkit.html describing the use of polkit as an
access control driver.
page.xsl is modified to support a new syntax
<div id="include" filename="somefile.htmlinc"/>
which will cause the XSL transform to replace that <div>
with the contents of 'somefile.htmlinc'. We use this in
the acl.html.in file, to pull the table of permissions
for each libvirt object. This table is autogenerated
from the enums in src/access/viraccessperms.h by the
genaclperms.pl script.
newapi.xsl is modified so that the list of permissions
checks shown against each API will link to the description
of the permissions in acl.html
Signed-off-by: Daniel P. Berrange <berrange@redhat.com>
So that app developers / admins know what access control checks
are performed for each API, this patch extends the API docs
generator to include details of the ACLs for each.
The gendispatch.pl script is extended so that it generates
a simple XML describing ACL rules, eg.
<aclinfo>
...
<api name='virConnectNumOfDomains'>
<check object='connect' perm='search_domains'/>
<filter object='domain' perm='getattr'/>
</api>
<api name='virDomainAttachDeviceFlags'>
<check object='domain' perm='write'/>
<check object='domain' perm='save' flags='!VIR_DOMAIN_AFFECT_CONFIG|VIR_DOMAIN_AFFECT_LIVE'/>
<check object='domain' perm='save' flags='VIR_DOMAIN_AFFECT_CONFIG'/>
</api>
...
</aclinfo>
The newapi.xsl template loads the XML files containing the ACL
rules and generates a short block of HTML for each API describing
the parameter checks and return value filters (if any).

This PCI controller, named "dmi-to-pci-bridge" in the libvirt config,
and implemented with qemu's "i82801b11-bridge" device, connects to a
PCI Express slot (e.g. one of the slots provided by the pcie-root
controller, aka "pcie.0" on the qemu commandline), and provides 31
*non-hot-pluggable* PCI (*not* PCIe) slots, numbered 1-31.
Any time a machine is defined which has a pcie-root controller
(i.e. any q35-based machinetype), libvirt will automatically add a
dmi-to-pci-bridge controller if one doesn't exist, and also add a
pci-bridge controller. The reasoning here is that any useful domain
will have either an immediate (startup time) or eventual (subsequent
hot-plug) need for a standard PCI slot; since the pcie-root controller
only provides PCIe slots, we need to connect a dmi-to-pci-bridge
controller to it in order to get a non-hot-plug PCI slot that we can
then use to connect a pci-bridge - the slots provided by the
pci-bridge will be both standard PCI and hot-pluggable.
Since pci-bridge devices themselves can not be hot-plugged into a
running system (although you can hot-plug other devices into a
pci-bridge's slots), any new pci-bridge controller that is added can
(and will) be plugged into the dmi-to-pci-bridge as long as it has
empty slots available.
This patch is also changing the qemuxml2xml-pcie test from a "DO_TEST"
to a "DO_DIFFERENT_TEST". This is so that the "before" xml can omit
the automatically added dmi-to-pci-bridge and pci-bridge devices, and
the "after" xml can include it - this way we are testing if libvirt is
properly adding these devices.
This controller is implicit on q35 machinetypes. It provides 31 PCIe
(*not* PCI) slots as controller 0.
Currently there are no devices that can connect to pcie-root, and no
implicit pci controller on a q35 machine, so q35 is still
unusable. For a usable q35 system, we need to add a
"dmi-to-pci-bridge" pci controller, which can connect to pcie-root,
and provides standard pci slots that can be used to connect other
devices.
The outbound/@peak is ignored (since QoS was introduced). This is due to
kernel limitation of know allowing ingress filters to have peak just
average rate. However, we should document this limitation to not confuse
users.
Interestingly, we had <code>floor<code> ... </code>outbound</code> which
results in much larger block of text to be written in code style that
intended.
There are two ways to use a iSCSI LUN as disk source for qemu.
* The LUN's path as it shows up on host, e.g.
/dev/disk/by-path/ip-$ip:3260-iscsi-$iqn-fc18:iscsi.iscsi0-lun-1
* The libiscsi URI from the storage pool source element host attribute, e.g.
iscsi://demo.org:6000/iqn.1992-01.com.example/1
For a "volume" type disk, if the specified "pool" is of iscsi
type, we should support to use the LUN in either of above 2 ways.
That's why to introduce a new XML tag "mode" for the disk source
(libvirt should support iscsi pool with libiscsi, but it's another
new feature, which should be done later).
The "mode" can be either of "host" or "direct". Use "host" to indicate
use of the LUN with the path as it shows up on host. Use "direct" to
indicate to use it with the source pool host URI (future patches may support
to use network type libvirt storage too, e.g. Ceph)
Makefiles are another easy file to enforce line limits.
Mostly straightforward; interesting tricks worth noting:
src/Makefile.am: $(confdir) was already defined, use it in more places
tests/Makefile.am: path_add and VG required some interesting compression
* cfg.mk (sc_prohibit_long_lines): Add another test.
* Makefile.am: Fix offenders.

On systems where git cannot access the outside world, a developer
can instead arrange to get a copy of gnulib at the right commit

then use ./autogen.sh --no-git. In this setup, we will now
avoid direct use of git. Of course, this means no automatic

Historically security issues in libvirt have been primarily
triaged & fixed by the Red Hat libvirt members & Red Hat
security team, who then usually notify other vendors via
appropriate channels. There have been a number of times
when vendors have not been properly notified ahead of
announcement. It has also disadvantaged community members
who have to backport fixes to releases for which there are
no current libvirt stable branches.
To address this, we want to make the libvirt security process
entirely community focused / driven. To this end I have setup
a new email address "libvirt-security@redhat.com" for end
users to report bugs which have (possible) security implications.
This email addr is backed by an invitation only, private
archive, mailing list. The intent is for the list membership
to comprise a subset of the libvirt core team, along with any
vendor security team engineers who wish to participate in a
responsible disclosure process for libvirt. Members of the
list will be responsible for analysing the problem to determine
if a security issue exists and then issue fixes for all current
official stable branches & git master.
I am proposing the following libvirt core team people as
members of the security team / list (all cc'd):
Daniel Berrange (Red Hat)
Eric Blake (Red Hat)
Jiri Denemar (Red Hat)
Daniel Veillard (Red Hat)
Jim Fehlig (SUSE)
Doug Goldstein (Gentoo)
Guido Günther (Debian)
We don't have anyone from Ubuntu on the libvirt core team.
Serge Hallyn is the most frequent submitter of patches from
Ubuntu in recent history, so I'd like to invite him to join.
Alternatively, Serge, feel free to suggest someone else to
represent Ubuntu's interests.
If any other vendors/distros have security people who are
responsible for dealing with libvirt security issues, and
want to join to get early disclosure of issues, they can
suggest people. Existing security team members will vet /
approve such requests to ensure they are genuine.
Anyone on the team / list will be **required** to honour any
embargo period agreed between members for non-public issues
that are reported. The aim will be to have a maximum 2 week
embargo period in the common case, extendable to 1 month if
there is sufficient justification made. If anyone feels they
are unable to follow such an embargo process for whatever
reason, please decline membership of the security list/team.
The patch which follows puts up some docs on the website
about all of this....
Document how to report security bugs and the process that
will be used for addressing them.

The XML tag is same with what we used internally for old RHEL.
network: static route support for <network>
This patch adds the <route> subelement of <network> to define a static
route. the address and prefix (or netmask) attribute identify the
destination network, and the gateway attribute specifies the next hop
address (which must be directly reachable from the containing
<network>) which is to receive the packets destined for
"address/(prefix|netmask)".
These attributes are translated into an "ip route add" command that is
executed when the network is started. The command used is of the
following form:
ip route add <address>/<prefix> via <gateway> \
dev <virbr-bridge> proto static metric <metric>
Tests are done to validate that the input data are correct. For
example, for a static route ip definition, the address must be a
network address and not a host address. Additional checks are added
to ensure that the specified gateway is directly reachable via this
network (i.e. that the gateway IP address is in the same subnet as one
of the IP's defined for the network).
prefix='0' is supported for both family='ipv4' address='0.0.0.0'
netmask='0.0.0.0' or prefix='0', and for family='ipv6' address='::',
prefix=0', although care should be taken to not override a desired
system default route.
Anytime an attempt is made to define a static route which *exactly*
duplicates an existing static route (for example, address=::,
prefix=0, metric=1), the following error message will be sent to
syslog:
RTNETLINK answers: File exists
This can be overridden by decreasing the metric value for the route
that should be preferred, or increasing the metric for the route that
shouldn't be preferred (and is thus in place only in anticipation that
the preferred route may be removed in the future). Caution should be
used when manipulating route metrics, especially for a default route.
Note: The use of the command-line interface should be replaced by
direct use of libnl so that error conditions can be handled better. But,
that is being left as an exercise for another day.

The rule generating the HTML docs passing the --html flag
to xsltproc. This makes it use the legacy HTML parser, which
either ignores or tries to fix all sorts of broken XML tags.
There's no reason why we should be writing broken XML in
the first place, so removing --html and adding the XHTML
doctype to all files forces us to create good XML.
This adds the XHTML doc type and fixes many, many XML tag
problems it exposes.

It's not desired to force users imagine path for a socket they
are not even supposed to connect to. On the other hand, we
already have a release where the qemu agent socket path is
exposed to XML, so we cannot silently drop it from there.
The new path is generated in form:
$LOCALSTATEDIR/lib/libvirt/qemu/channel/target/$domain.$name
for qemu system mode, and
$XDG_CONFIG_HOME/qemu/lib/channel/target/$domain.$name
for qemu session mode.
Commit cc6d19f3 added text containing "<code>snapshot<code>" to
formatsnapshot.html.in. The closing tag is missing '/' which causes
the documentation to misrender.
A domain's <interface> or <hostdev>, as well as a <network>'s
<forward>, can now have an optional <driver name='kvm|vfio'/>
element. As of this patch, there is no functionality behind this new
knob - this patch adds support to the domain and network
formatter/parser, and to the RNG and documentation.
When the backend is added, legacy KVM PCI device assignment will
continue to be used when no driver name is specified (or if <driver
name='kvm'/> is specified), but if driver name is 'vfio', the new UEFI
Secure Boot compatible VFIO device assignment will be used.
Note that the parser doesn't automatically insert the current default
value of this setting. This is done on purpose because the two
possibilities are functionally equivalent from the guest's point of
view, and we want to be able to automatically start using vfio as the
default (even for existing domains) at some time in the future. This
is similar to what was done with the "vhost" driver option in
<interface>.
For pSeries guest in QEMU, NVRAM is one kind of spapr-vio device.
Users are allowed to specify spapr-vio devices'address.
But NVRAM is not supported in libvirt. So this patch is to
add NVRAM device to allow users to specify its address.
In QEMU, NVRAM device's address is specified by
"-global spapr-nvram.reg=xxxxx".
In libvirt, XML file is defined as the following:
<nvram>
<address type='spapr-vio' reg='0x3000'/>
</nvram>
