2bb520c802 qemu: Support mountpoints option of guest-fsfreeze-freeze
With this patch, virDomainFSFreeze will pass the mountpoints argument
to qemu guest agent. For example,

  virDomainFSFreeze(dom, {"/mnt/vol1", "/mnt/vol2"}, 2, 0)

will issue qemu guest agent command:

  {"execute":"guest-fsfreeze-freeze",
   "arguments":{"mountpoints":["/mnt/vol1","/mnt/vol2"]}}

f3be5f0c50 Add support for timestamping QEMU logs
QEMU commit 5e2ac51 added a boolean '-msg timestamp=[on|off]'
option, which can enable timestamps on errors:
$ qemu-system-x86_64 -msg timestamp=on zghhdorf
2014-04-09T13:25:46.779484Z qemu-system-x86_64: -msg timestamp=on: could
not open disk image zghhdorf: Could not open 'zghhdorf': No such file or
directory

Enable this timestamp if the QEMU binary supports it.

Add a 'log_timestamp' option to qemu.conf for disabling this behavior.

1e947cf7d8 qemu: specify domain in host-side PCI addresses when needed/supported
This uses the new QEMU_CAPS_HOST_PCI_MULTIDOMAIN capability when
present, for -devivce pci-assign, -device vfio-pci, and -pcidevice.

While creating tests for this new functionality, I noticed that the
xmls for two existing tests had erroneously specified an
until-now-ignored domain="0x0002", so I corrected those two tests, and
also added two failure tests to be sure that we alert users who
attempt to use a non-zero domain with a qemu that doesn't support it.

17133e3702 qemu: add host-pci-multidomain capability
Quite a long time ago, (apparently between qemu 0.12 and 0.13) qemu
quietly began supporting the optional specification of a domain in the
host-side address of all pci passthrough commands (by simply
prepending it to the bus:slot.function format, as
"dddd:bb:ss.f"). Since machines with multiple PCI domains are very
rare, this never came up in practice, so libvirt was never updated to
support it.

This patch takes the first step to supporting specification of a non-0
domain in the host-side address of PCI devices being assigned to a
domain, by adding a capability bit to indicate support
"QEMU_CAPS_HOST_PCI_MULTIDOMAIN", and detect it. Since this support
was added in a version prior to the minimum version required for
QMP-style capabilities detection, the capability is always enabled for
any qemu that uses QMP for capabilities detection. For older qemus,
the only clue that a domain can be specified in the host pci address
is the presence of the string "[seg:]" in the help string for
-pcidevice. (Ironically, libvirt will not be modified to support
specification of domain for -pcidevice, since any qemu new enough for
us to care about also supports "-device pci-assign" or "-device
vfio-pci", which are greatly preferred).

gnutls-3.3.0 and newer leaves 2 FDs open in order to be backwards

7b045c8ce9 util: new stricter unsigned int parsing
strtoul() is required to parse negative numbers as their
twos-complement positive counterpart.  But sometimes we want

The 'p' suffix is a mnemonic for 'positive' (technically it

nice one-letter suffix).

f18c02ec22 util: fix uint parsing on 64-bit platforms
Commit f22b7899 called to light a long-standing latent bug: the
behavior of virStrToLong_ui was different on 32-bit platforms
than on 64-bit platforms.  Curse you, C type promotion and
narrowing rules, and strtoul specification.  POSIX says that for
a 32-bit long, strtol handles only 2^32 values [LONG_MIN to
LONG_MAX] while strtoul handles 2^33 - 1 values [-ULONG_MAX to
ULONG_MAX] with twos-complement wraparound for negatives.  Thus,
parsing -1 as unsigned long produces ULONG_MAX, rather than a
range error.  We WANT[1] this same shortcut for turning -1 into
UINT_MAX when parsing to int; and get it for free with 32-bit
long.  But with 64-bit long, ULONG_MAX is outside the range
of int and we were rejecting it as invalid; meanwhile, we were
silently treating -18446744073709551615 as 1 even though it
textually exceeds INT_MIN.  Too bad there's not a strtoui() in
libc that does guaranteed parsing to int, regardless of the size
of long.

The bug has been latent since 2007, introduced by Jim Meyering
in commit 5d25419 in the attempt to eradicate unsafe use of
strto[u]l when parsing ints and longs.  How embarrassing that we
are only discovering it now - so I'm adding a testsuite to ensure
that it covers all the corner cases we care about.

[1] Ideally, we really want the caller to be able to choose whether
to allow negative numbers to wrap around to their 2s-complement
counterpart, as in strtoul, or to force a stricter input range
of [0 to UINT_MAX] by rejecting negative signs; this will be added
in a later patch for all three int types.

This patch is tested on both 32- and 64-bit; the enhanced
virstringtest passes on both platforms, while virstoragetest now
reliably fails on both platforms instead of just 32-bit platforms.
That test will be fixed later.

* src/util/virstring.c (virStrToLong_ui): Ensure same behavior
regardless of platform long size.
* tests/virstringtest.c (testStringToLong): New function.
(mymain): Comprehensively test string to long parsing.

3a0ca7de51 Introduce an object for managing firewall rulesets
The network and nwfilter drivers both have a need to update
firewall rules. The currently share no code for interacting
with iptables / firewalld. The nwfilter driver is fairly
tied to the concept of creating shell scripts to execute
which makes it very hard to port to talk to firewalld via
DBus APIs.

This patch introduces a virFirewallPtr object which is able
to represent a complete sequence of rule changes, with the
ability to have multiple transactional checkpoints with
rollbacks. By formally separating the definition of the rules
to be applied from the mechanism used to apply them, it is
also possible to write a firewall engine that uses firewalld
DBus APIs natively instead of via the slow firewalld-cmd.

f22b7899a8 Add support for addressing backing stores by index
Each backing store of a given disk is associated with a unique index
(which is also formatted in domain XML) for easier addressing of any
particular backing store. With this patch, any backing store can be
addressed by its disk target and the index. For example, "vdc[4]"
addresses the backing store with index equal to 4 of the disk identified
by "vdc" target. Such shorthand can be used in any API in place for a
backing file path:

546154e3d4 conf: Format and parse backing chains in domain XML
This patch implements formating and parsing code for the backing store
schema defined and documented by the previous patch.

This patch does not aim at providing full persistent storage of disk
backing chains yet. The formatter is supposed to provide the backing
chain detected when starting a domain and thus it is not formatted into
an inactive domain XML. The parser is implemented mainly for the purpose
of testing the XML generated by the formatter and thus it does not
distinguish between no backingStore element and an empty backingStore
element. This will have to change once we fully implement support for
user-supplied backing chains.

  </disk>

Various disk types and formats can be mixed in one chain. The
<backingStore/> empty element marks the end of the backing chain and it
is there mostly for future support of parsing the chain provided by a
user. If it's missing, we are supposed to probe for the rest of the
chain ourselves, otherwise complete chain was provided by the user. The
index attributes of backingStore elements can be used to unambiguously
identify a specific part of the image chain.

8823272d41 util: storage: Invert the way recursive metadata retrieval works
To avoid having the root of a backing chain present twice in the list we
need to invert the working of virStorageFileGetMetadataRecurse.

Until now the recursive worker created a new backing chain element from
the name and other information passed as arguments. This required us to
pass the data of the parent in a deconstructed way and the worker
created a new entry for the parent.

This patch converts this function so that it just fills in metadata
about the parent and creates a backing chain element from those. This
removes the duplication of the first element.

To avoid breaking the test suite, virstoragetest now calls a wrapper
that creates the parent structure explicitly and pre-fills it with the
test data with same function signature as previously used.

7b6b9d3863 PPC64 prefers to set pci-ohci controller as default USB controller.
Currently, libvirt is using legacy USB controller as default. There
are problems with VGA which can't work correctly with USB Keyboard and
USB Mouse.

While providing -nodefaults, ppc64 should be specifying the usb
controller explicitly in place of using the legacy
controller(-usb). Qemu spapr initialization code when sees "-usb" adds a
USB Keyboard and USB Mouse by default. And libvirt has added a USB
keyboard and USB mouse.

A recent fix in the in qemu VGA code uncoverd this problem, which
resulted in addition of extra keyboard and mouse to the qemu machine.

This patch is to set pci-ohci as USB default controller.

8fb446754d conf: fix omission of <driver> in domain dumpxml
I noticed that depending on the <driver> attributes the user passed
in, the output may omit the <driver> element altogether.  For example,
the rerror_policy has had this problem since commit 4bb4109 in Oct
2011.  But in adding testsuite coverage to expose it, I found another
problem: the C code is just fine without a driver name, but the
XML validator required either a name or a cache mode.

* src/conf/domain_conf.c (virDomainDiskDefFormat): Update
conditional.
* docs/schemas/domaincommon.rng (diskDriver): Simplify.
* tests/qemuxml2argvdata/qemuxml2argv-disk-drive-copy-on-read.xml:
* tests/qemuxml2argvdata/qemuxml2argv-disk-drive-copy-on-read.args:
New files.
* tests/qemuxml2argvdata/qemuxml2argv-disk-drive-discard.xml:
Enhance test.
* tests/qemuxml2xmloutdata/qemuxml2xmlout-disk-drive-discard.xml:
Likewise.
* tests/qemuxml2argvtest.c (mymain): New test.
* tests/qemuxml2xmltest.c (mymain): Likewise.

fec1a93927 conf: split <disk> schema into more pieces
To make <disk> schema more maintainable and to allow for moving the
pieces to a common file in the future. It relies on the ability to
override definitions as part of an include, set up in the previous
patch.

The diff is a bit hard to read, because it mixes reindentation
with refactoring; 'git diff -b --patience' may help.

* docs/schemas/domaincommon.rng (disk): Refactor into pieces.
(diskSource, diskSourceFile, diskSourceBlock, diskSourceDir)
(diskSourceVolume: New defines.
(diskSourceNetwork): Revise scope.
* docs/schemas/domainsnapshot.rng (disksnapshot): Adjust.
* tests/domainsnapshotxml2xmlin/disk-seclabel-invalid.xml,
tests/domainsnapshotxml2xmlin/disk-network-seclabel-invalid.xml: New
tests to check seclabel is forbidden in domain snapshot by schema.

369cdfa8f5 conf: set up for per-grammar overrides in schemas
This patch is my first experience playing with nested grammars,
as documented in http://relaxng.org/tutorial-20011203.html#IDA3PZR.
I plan on doing more overrides in order to make the RelaxNG
grammar mirror the C code refactoring into a common
virStorageSource, but where different clients of that source do
not support the same subset of functionality.  By starting with
something fairly easy to validate, I can make sure my later
patches will be possible.

This patch adds a use of the no-op <ref
name='sourceStartupPolicy'/> to the disksnapshot definition, so
that the snapshot version of a type='file' <source> more closely
resembles the version in domaincommon.  A future patch will merge
the two files into using a common define, but this patch is
sufficient for testing that adding <source
startupPolicy='optional'/> in any of the
tests/domainsnapshotxml2xmlin/*.xml files still gets rejected
unless it occurs within the <domain> subelement, because the
definition of startupPolicy is empty outside of domain.rng.

* docs/schemas/storagecommon.rng (storageStartupPolicy)
(storageSourceExtra): Create no-op defaults.
* docs/schemas/domainsnapshot.rng (domain): Use nested grammar
to avoid restricting <domain>.
(storageSourceExtra): Create new override.
(disksnapshot): Access overrides through common names.
* docs/schemas/domaincommon.rng (disk): Access overrides through
common names.
* docs/schemas/domain.rng (storageStartupPolicy)
(storageSourceExtra): Create new overrides.
