Add two new security label types
Curently security labels can be of type 'dynamic' or 'static'.
If no security label is given, then 'dynamic' is assumed. The
current code takes advantage of this default, and avoids even
saving <seclabel> elements with type='dynamic' to disk. This
means if you temporarily change security driver, the guests
can all still start.
With the introduction of sVirt to LXC though, there needs to be
a new default of 'none' to allow unconfined LXC containers.
This patch introduces two new security label types
- default: the host configuration decides whether to run the
guest with type 'none' or 'dynamic' at guest start
- none: the guest will run unconfined by security policy
The 'none' label type will obviously be undesirable for some
deployments, so a new qemu.conf option allows a host admin to
mandate confined guests. It is also possible to turn off default
confinement

seclabel: extend XML to allow per-disk label overrides
When doing security relabeling, there are cases where a per-file
override might be appropriate. For example, with a static label
and relabeling, it might be appropriate to skip relabeling on a
particular disk, where the backing file lives on NFS that lacks
the ability to track labeling. Or with dynamic labeling, it might
be appropriate to use a custom (non-dynamic) label for a disk
specifically intended to be shared across domains.
The new XML resembles the top-level <seclabel>, but with fewer
options (basically relabel='no', or <label>text</label>):
<domain ...>
...
<devices>
<disk type='file' device='disk'>
<source file='/path/to/image1'>
<seclabel relabel='no'/> <!-- override for just this disk -->
</source>
...
</disk>
<disk type='file' device='disk'>
<source file='/path/to/image1'>
<seclabel relabel='yes'> <!-- override for just this disk -->
<label>system_u:object_r:shared_content_t:s0</label>
</seclabel>
</source>
...
</disk>
...
</devices>
<seclabel type='dynamic' model='selinux'>
<baselabel>text</baselabel> <!-- used for all devices without override -->
</seclabel>
</domain>
This patch only introduces the XML and documentation; future patches
will actually parse and make use of it. The intent is that we can
further extend things as needed, adding a per-device <seclabel> in
more places (such as the source of a console device), and possibly
allowing a <baselabel> instead of <label> for labeling where we want
to reuse the cNNN,cNNN pair of a dynamically labeled domain but a
different base label.

selinux: distinguish failure to label from request to avoid label
https://bugzilla.redhat.com/show_bug.cgi?id=924153
Commit 904e05a2 (v0.9.9) added a per-<disk> seclabel element with
an attribute relabel='no' in order to try and minimize the
impact of shutdown delays when an NFS server disappears. The idea
was that if a disk is on NFS and can't be labeled in the first
place, there is no need to attempt the (no-op) relabel on domain
shutdown. Unfortunately, the way this was implemented was by
modifying the domain XML so that the optimization would survive
libvirtd restart, but in a way that is indistinguishable from an
explicit user setting. Furthermore, once the setting is turned
on, libvirt avoids attempts at labeling, even for operations like
snapshot or blockcopy where the chain is being extended or pivoted
onto non-NFS, where SELinux labeling is once again possible. As
a result, it was impossible to do a blockcopy to pivot from an
NFS image file onto a local file.
The solution is to separate the semantics of a chain that must
not be labeled (which the user can set even on persistent domains)
vs. the optimization of not attempting a relabel on cleanup (a
live-only annotation), and using only the user's explicit notation
rather than the optimization as the decision on whether to skip
a label attempt in the first place. When upgrading an older
libvirtd to a newer, an NFS volume will still attempt the relabel;
but as the avoidance of a relabel was only an optimization, this
shouldn't cause any problems.
In the ideal future, libvirt will eventually have XML describing
EVERY file in the backing chain, with each file having a separate
<seclabel> element. At that point, libvirt will be able to track
more closely which files need a relabel attempt at shutdown. But
until we reach that point, the single <seclabel> for the entire
<disk> chain is treated as a hint - when a chain has only one
file, then we know it is accurate; but if the chain has more than
one file, we have to attempt relabel in spite of the attribute,
in case part of the chain is local and SELinux mattered for that
portion of the chain.

Commit 904e05a2 (v0.9.9) added a per-<disk> seclabel element with
an attribute relabel='no' in order to try and minimize the
impact of shutdown delays when an NFS server disappears. The idea
was that if a disk is on NFS and can't be labeled in the first
place, there is no need to attempt the (no-op) relabel on domain
shutdown. Unfortunately, the way this was implemented was by
modifying the domain XML so that the optimization would survive
libvirtd restart, but in a way that is indistinguishable from an
explicit user setting. Furthermore, once the setting is turned
on, libvirt avoids attempts at labeling, even for operations like
snapshot or blockcopy where the chain is being extended or pivoted
onto non-NFS, where SELinux labeling is once again possible. As
a result, it was impossible to do a blockcopy to pivot from an
NFS image file onto a local file.
The solution is to separate the semantics of a chain that must
not be labeled (which the user can set even on persistent domains)
vs. the optimization of not attempting a relabel on cleanup (a
live-only annotation), and using only the user's explicit notation
rather than the optimization as the decision on whether to skip
a label attempt in the first place. When upgrading an older
libvirtd to a newer, an NFS volume will still attempt the relabel;
but as the avoidance of a relabel was only an optimization, this
shouldn't cause any problems.
In the ideal future, libvirt will eventually have XML describing
EVERY file in the backing chain, with each file having a separate
<seclabel> element. At that point, libvirt will be able to track
more closely which files need a relabel attempt at shutdown. But
until we reach that point, the single <seclabel> for the entire
<disk> chain is treated as a hint - when a chain has only one
file, then we know it is accurate; but if the chain has more than
one file, we have to attempt relabel in spite of the attribute,
in case part of the chain is local and SELinux mattered for that
portion of the chain.

seclabel: extend XML to allow per-disk label overrides
When doing security relabeling, there are cases where a per-file
override might be appropriate. For example, with a static label
and relabeling, it might be appropriate to skip relabeling on a
particular disk, where the backing file lives on NFS that lacks
the ability to track labeling. Or with dynamic labeling, it might
be appropriate to use a custom (non-dynamic) label for a disk
specifically intended to be shared across domains.
The new XML resembles the top-level <seclabel>, but with fewer
options (basically relabel='no', or <label>text</label>):
<domain ...>
...
<devices>
<disk type='file' device='disk'>
<source file='/path/to/image1'>
<seclabel relabel='no'/> <!-- override for just this disk -->
</source>
...
</disk>
<disk type='file' device='disk'>
<source file='/path/to/image1'>
<seclabel relabel='yes'> <!-- override for just this disk -->
<label>system_u:object_r:shared_content_t:s0</label>
</seclabel>
</source>
...
</disk>
...
</devices>
<seclabel type='dynamic' model='selinux'>
<baselabel>text</baselabel> <!-- used for all devices without override -->
</seclabel>
</domain>
This patch only introduces the XML and documentation; future patches
will actually parse and make use of it. The intent is that we can
further extend things as needed, adding a per-device <seclabel> in
more places (such as the source of a console device), and possibly
allowing a <baselabel> instead of <label> for labeling where we want
to reuse the cNNN,cNNN pair of a dynamically labeled domain but a
different base label.

numad: Set memory policy from numad advisory nodeset
Though numad will manage the memory allocation of task dynamically,
it wants management application (libvirt) to pre-set the memory
policy according to the advisory nodeset returned from querying numad,
(just like pre-bind CPU nodeset for domain process), and thus the
performance could benefit much more from it.
This patch introduces new XML tag 'placement', value 'auto' indicates
whether to set the memory policy with the advisory nodeset from numad,
and its value defaults to the value of <vcpu> placement, or 'static'
if 'nodeset' is specified. Example of the new XML tag's usage:
<numatune>
<memory placement='auto' mode='interleave'/>
</numatune>
Just like what current "numatune" does, the 'auto' numa memory policy
setting uses libnuma's API too.
If <vcpu> "placement" is "auto", and <numatune> is not specified
explicitly, a default <numatume> will be added with "placement"
set as "auto", and "mode" set as "strict".
The following XML can now fully drive numad:
1) <vcpu> placement is 'auto', no <numatune> is specified.
<vcpu placement='auto'>10</vcpu>
2) <vcpu> placement is 'auto', no 'placement' is specified for
<numatune>.
<vcpu placement='auto'>10</vcpu>
<numatune>
<memory mode='interleave'/>
</numatune>
And it's also able to control the CPU placement and memory policy
independently. e.g.
1) <vcpu> placement is 'auto', and <numatune> placement is 'static'
<vcpu placement='auto'>10</vcpu>
<numatune>
<memory mode='strict' nodeset='0-10,^7'/>
</numatune>
2) <vcpu> placement is 'static', and <numatune> placement is 'auto'
<vcpu placement='static' cpuset='0-24,^12'>10</vcpu>
<numatune>
<memory mode='interleave' placement='auto'/>
</numatume>
A follow up patch will change the XML formatting codes to always output
'placement' for <vcpu>, even it's 'static'.

(just like pre-bind CPU nodeset for domain process), and thus the
performance could benefit much more from it.
This patch introduces new XML tag 'placement', value 'auto' indicates
whether to set the memory policy with the advisory nodeset from numad,
and its value defaults to the value of <vcpu> placement, or 'static'
if 'nodeset' is specified. Example of the new XML tag's usage:
<numatune>
<memory placement='auto' mode='interleave'/>
</numatune>
Just like what current "numatune" does, the 'auto' numa memory policy
setting uses libnuma's API too.
If <vcpu> "placement" is "auto", and <numatune> is not specified
explicitly, a default <numatume> will be added with "placement"
set as "auto", and "mode" set as "strict".
The following XML can now fully drive numad:
1) <vcpu> placement is 'auto', no <numatune> is specified.
<vcpu placement='auto'>10</vcpu>
2) <vcpu> placement is 'auto', no 'placement' is specified for
<numatune>.
<vcpu placement='auto'>10</vcpu>
<numatune>
<memory mode='interleave'/>
</numatune>
And it's also able to control the CPU placement and memory policy
independently. e.g.
1) <vcpu> placement is 'auto', and <numatune> placement is 'static'
<vcpu placement='auto'>10</vcpu>
<numatune>
<memory mode='strict' nodeset='0-10,^7'/>
</numatune>
2) <vcpu> placement is 'static', and <numatune> placement is 'auto'
<vcpu placement='static' cpuset='0-24,^12'>10</vcpu>
<numatune>
<memory mode='interleave' placement='auto'/>
</numatume>
A follow up patch will change the XML formatting codes to always output
'placement' for <vcpu>, even it's 'static'.

blockjob: enhance xml to track mirrors across libvirtd restart
In order to track a block copy job across libvirtd restarts, we
need to save internal XML that tracks the name of the file
holding the mirror. Displaying this name in dumpxml might also
be useful to the user, even if we don't yet have a way to (re-)
start a domain with mirroring enabled up front. This is done
with a new <mirror> sub-element to <disk>, as in:
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/var/lib/libvirt/images/original.img'/>
<mirror file='/var/lib/libvirt/images/copy.img' format='qcow2' ready='yes'/>
...
</disk>
For now, the element is output-only, in live domains; it is ignored
when defining a domain or hot-plugging a disk (since those contexts
use VIR_DOMAIN_XML_INACTIVE in parsing). The 'ready' attribute appears
when libvirt knows that the job has changed from the initial pulling
phase over to the mirroring phase, although absence of the attribute
is not a sure indicator of the current phase. If we come up with a way
to make qemu start with mirroring enabled, we can relax the xml
restriction, and allow <mirror> (but not attribute 'ready') on input.
Testing active-only XML meant tweaking the testsuite slightly, but it
was worth it.

seclabel: extend XML to allow per-disk label overrides
When doing security relabeling, there are cases where a per-file
override might be appropriate. For example, with a static label
and relabeling, it might be appropriate to skip relabeling on a
particular disk, where the backing file lives on NFS that lacks
the ability to track labeling. Or with dynamic labeling, it might
be appropriate to use a custom (non-dynamic) label for a disk
specifically intended to be shared across domains.
The new XML resembles the top-level <seclabel>, but with fewer
options (basically relabel='no', or <label>text</label>):
<domain ...>
...
<devices>
<disk type='file' device='disk'>
<source file='/path/to/image1'>
<seclabel relabel='no'/> <!-- override for just this disk -->
</source>
...
</disk>
<disk type='file' device='disk'>
<source file='/path/to/image1'>
<seclabel relabel='yes'> <!-- override for just this disk -->
<label>system_u:object_r:shared_content_t:s0</label>
</seclabel>
</source>
...
</disk>
...
</devices>
<seclabel type='dynamic' model='selinux'>
<baselabel>text</baselabel> <!-- used for all devices without override -->
</seclabel>
</domain>
This patch only introduces the XML and documentation; future patches
will actually parse and make use of it. The intent is that we can
further extend things as needed, adding a per-device <seclabel> in
more places (such as the source of a console device), and possibly
allowing a <baselabel> instead of <label> for labeling where we want
to reuse the cNNN,cNNN pair of a dynamically labeled domain but a
different base label.

snapshot: also support disks by path
I got confused when 'virsh domblkinfo dom disk' required the
path to a disk (which can be ambiguous, since a single file
can back multiple disks), rather than the unambiguous target
device name that I was using in disk snapshots. So, in true
developer fashion, I went for the best of both worlds - all
interfaces that operate on a disk (aka block) now accept
either the target name or the unambiguous path to the backing
file used by the disk.

blockjob: enhance xml to track mirrors across libvirtd restart
In order to track a block copy job across libvirtd restarts, we
need to save internal XML that tracks the name of the file
holding the mirror. Displaying this name in dumpxml might also
be useful to the user, even if we don't yet have a way to (re-)
start a domain with mirroring enabled up front. This is done
with a new <mirror> sub-element to <disk>, as in:
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/var/lib/libvirt/images/original.img'/>
<mirror file='/var/lib/libvirt/images/copy.img' format='qcow2' ready='yes'/>
...
</disk>
For now, the element is output-only, in live domains; it is ignored
when defining a domain or hot-plugging a disk (since those contexts
use VIR_DOMAIN_XML_INACTIVE in parsing). The 'ready' attribute appears
when libvirt knows that the job has changed from the initial pulling
phase over to the mirroring phase, although absence of the attribute
is not a sure indicator of the current phase. If we come up with a way
to make qemu start with mirroring enabled, we can relax the xml
restriction, and allow <mirror> (but not attribute 'ready') on input.
Testing active-only XML meant tweaking the testsuite slightly, but it
was worth it.

rng: tighten up domain <controller> schema
The rng schema for <controller> had been non-specific about which
types of controllers allowed which models, and also allowed the
num_queues attribute (since that hasn't been released yet, should we
rename it to "numQueues"?) and <master> subelement to be included for
any controller type. In reality, half of the models are allowed only
for type='scsi', and the other half only for type='usb', num_queues is
allowed only for type='scsi', and <master> only for type='usb'.
This patch makes a separate <group> for type='scsi' and type='usb',
with each group allowing only the appropriate model values, and
allowing num_queue and <master> only when appropriate.
<interleave> also hadn't been specified, forcing a specific order of
subelements, which should never be done. (Note that the <interleave>
had to surround the main element attributes that are in the <group>
subelements, due to one of the <group>s containing a subelement).

LXC: Fix handling of RAM filesystem size units
Since 76b644c when the support for RAM filesystems was introduced,
libvirt accepted the following XML:
<source usage='1024' unit='KiB'/>
This was parsed correctly and internally stored in bytes, but it
was formatted as (with an extra 's'):
<source usage='1024' units='KiB'/>
When read again, this was treated as if the units were missing,
meaning libvirt was unable to parse its own XML correctly.
The usage attribute was documented as being in KiB, but it was not
scaled if the unit was missing. Transient domains still worked,
because this was balanced by an extra 'k' in the mount options.
This patch:
Changes the parser to use 'units' instead of 'unit', as the latter
was never documented (fixing persistent domains) and some programs
(libvirt-glib, libvirt-sandbox) already parse the 'units' attribute.
Removes the extra 'k' from the tmpfs mount options, which is needed
because now we parse our own XML correctly.
Changes the default input unit to KiB to match documentation, fixing:

blockjob: enhance xml to track mirrors across libvirtd restart
In order to track a block copy job across libvirtd restarts, we
need to save internal XML that tracks the name of the file
holding the mirror. Displaying this name in dumpxml might also
be useful to the user, even if we don't yet have a way to (re-)
start a domain with mirroring enabled up front. This is done
with a new <mirror> sub-element to <disk>, as in:
<disk type='file' device='disk'>
<driver name='qemu' type='raw'/>
<source file='/var/lib/libvirt/images/original.img'/>
<mirror file='/var/lib/libvirt/images/copy.img' format='qcow2' ready='yes'/>
...
</disk>
For now, the element is output-only, in live domains; it is ignored
when defining a domain or hot-plugging a disk (since those contexts
use VIR_DOMAIN_XML_INACTIVE in parsing). The 'ready' attribute appears
when libvirt knows that the job has changed from the initial pulling
phase over to the mirroring phase, although absence of the attribute
is not a sure indicator of the current phase. If we come up with a way
to make qemu start with mirroring enabled, we can relax the xml
restriction, and allow <mirror> (but not attribute 'ready') on input.
Testing active-only XML meant tweaking the testsuite slightly, but it
was worth it.
