Michal Privoznik 75597f022a qemu: Warn verbosely if using old loader:nvram pairs
There are two ways for specifying loader:nvram pairs:

  1) --with-loader-nvram configure option
  2) nvram variable in qemu.conf

Since we have FW descriptors, using this old style is
discouraged, but not as strong as one would expect. Produce more
warnings:

  1) produce a warning if somebody tries the configure option
  2) produce a warning if somebody sets nvram variable and at
     least on FW descriptor was found

The reason for producing warning in case 1) is that package
maintainers, who set the configure option in the first place
should start moving towards FW descriptors and abandon the
configure option. After all, the warning is printed into config
output only in this case.

Libvirtd has set SIGPIPE to ignored, and virFork resets all signal
handlers to the defaults. But child process may write logs to
stderr/stdout, that may generate SIGPIPE if journald has stopped.

So set SIGPIPE to a dummy no-op handler before unmask signals in
virFork(), and the handler will get reset to SIG_DFL when execve()
runs. Now we can delete sigaction() call entirely in virExec().

Laine Stump 13ec827052 util: set bridge device MAC address explicitly during virNetDevBridgeCreate
When libvirt first implemented a stable and configurable MAC address
for the bridges created for libvirt virtual networks (commit
5754dbd56d, in libvirt v0.8.8) most distro stable releases didn't
support explicitly setting the MAC address of a bridge; the bridge
just always assumed the lowest numbered MAC of all attached
interfaces. Because of this, we stabilized the bridge MAC address by
creating a "dummy" tap interface with a MAC address guaranteed to be
lower than any of the guest tap devices' MACs (which all started with
0xFE, so it's not difficult to do) and attached it to the bridge -
this was the inception of the "virbr0-nic" device that has confused so
many people over the years.

Even though the linux kernel had recently gained support for
explicitly setting a bridge MAC, we deemed it unnecessary to set the
MAC that way, because the other (indirect) method worked everywhere.

But recently there have been reports that the bridge MAC address was
not following the setting in the network config, and mismatched the
MAC of the dummy tap device (which was still correct). It turns out
that this is due to a change in systemd-242 that persists whatever MAC
address is set for a bridge when it's initially started. According to
the systemd NEWS file entry for version 242
(https://github.com/systemd/systemd/blob/master/NEWS):

  "if a bridge interface is created without any slaves, and gains
   a slave later, then now the bridge does not inherit slave's MAC."

This change was the result of:

  https://github.com/systemd/systemd/issues/3374

(apparently if there is no MAC saved for a bridge by the name of a
bridge being created, the random MAC generated during creation is
saved, and then that same MAC is used to explicitly set the MAC each
time it is created). Once a bridge has an explicitly set MAC, the "use
the lowest numbered MAC of attached devices" rule is ignored, so our
dummy tap device is like the goggles - it does nothing! (well, almost).

We could whine about changes in default behavior, etc. etc., but
because the change was in response to actual user problems, that seems
likely a fruitless task. Fortunately, time has marched on, and even
distro releases that are old enough that they are no longer supported
by upstream libvirt (e.g. RHEL6) have support for explicitly setting a
bridge device MAC address, either during creation or with a separate
ioctl after creation, so we can now do that.

To enable explicitly setting the mac during bridge creation, we add a
mac arg to virNetDevBridgeCreate().  In the case of platforms where
the bridge is created with a netlink RTM_NEWLINK message, we just add
that mac to the message. For platforms that still use an ioctl (either
SIOCBRADDBR or SIOCIFCREATE2), we make a separate call to
virNetDevSetMAC() after creating the bridge.

(NB: I was unable to test the calling of virNetDevSetMAC() from the
SIOCIFCREATE2 (BSD) version of virNetDevBridgeCreate(); even though I
managed to get a FreeBSD system setup and libvirt built there, when I
tried to start the default network the SIOCIFCREATE2 ioctl itself
failed, so it never even got to the virNetDevSetMAC(). That leaves the
FreeBSD implementation untested.)

This makes the dummy tap pointless for purposes of setting the MAC
address, but it is still useful for IPv6 DAD initialization (which
apparently requires at least one interface to be attached to the
bridge and online), as well as for setting an initial MTU for the
bridge, so it hasn't been removed.

(NB: we can safely *always* call virNetDevBridgeCreate() with
&def->mac from the network driver because, in spite of the existence
of a "mac_specified" bool in the config suggesting that it may not
always be present, in reality a mac address will always be added to
any network that doesn't have one - this is guaranteed in all cases by
commit a47ae7c004)

Although until now, any use of the extra_args argument (a pointer to a
struct containing extra attributes to add the the RTM_NEWLINK message)
would always have the ifindex and mac set, so the code could assume it
was safe to add both to the message if extra_args != NULL. There is
now a use for setting a MAC address in the RTM_NEWLINK without setting
the ifindex, so we should check each of these separately.

Laine Stump 47a7b8a96b qemu: avoid double reservation of PCI address for interface type='hostdev'
Commit 01ca4010d8 (libvirt v5.1.0) moved address reservation for
hotplugged interface devices up to an earlier point in
qemuDomainAttachNetDevice(), because that function calls
qemuDomainSupportsNicdev() (in the case of
VIR_DOMAIN_NET_TYPE_VHOSTUSER), and qemuDomainSupportsNicdev() needs
to know the address type (for ARM machinetypes) and returns incorrect
results when the address type is "none".

This bugfix unfortunately caused a regression, because it also made PCI
address reservation happen before we noticed that the device was a
*hostdev* interface. Those interfaces are hotplugged by just calling
out to qemuDomainAttachHostdevDevice() - that function would then also
attempt to reserve the *same PCI address* that had just been reserved
in qemuDomainAttachNetDevice().

The solution is to move the bit of code that short-circuits out to
virDomainHostdevAttach() up *even earlier* so that no PCI address has
been allocated by the time it's called.

Peter Krempa 5fdad0db2c util: buffer: Properly URLencode strings
According to rfc3986:

2.3.  Unreserved Characters

   Characters that are allowed in a URI but do not have a reserved
   purpose are called unreserved.  These include uppercase and lowercase
   letters, decimal digits, hyphen, period, underscore, and tilde.

      unreserved  = ALPHA / DIGIT / "-" / "." / "_" / "~"

   URIs that differ in the replacement of an unreserved character with
   its corresponding percent-encoded US-ASCII octet are equivalent: they
   identify the same resource.  However, URI comparison implementations
   do not always perform normalization prior to comparison (see Section
   6).  For consistency, percent-encoded octets in the ranges of ALPHA
   (%41-%5A and %61-%7A), DIGIT (%30-%39), hyphen (%2D), period (%2E),
   underscore (%5F), or tilde (%7E) should not be created by URI
   producers and, when found in a URI, should be decoded to their
   corresponding unreserved characters by URI normalizers.

Thus we must not include few other characters which don't match
c_isalpha to conform to the rules.

can't be changed or that the target is unique, so limiting the search to
disks with same bus makes no sense.

Peter Krempa 2c37dc7bda conf: Reset disk type if <source> element is completely missing
The disk type is not part of source and thus it's parsed earlier. This
bypasses the checks when parsing a disk type='network' if it's
completely missing the source.

Since there are possible active users of this (it was reported as a
problem with openstack) fix it by resetting the disk type to '_FILE' for
an empty cdrom which is handled correctly.

only restricts traffic on the INPUT and/or FORWARD rules,
some users might have custom firewalls that restrict the
OUTPUT rules too.

These can prevent DHCP/DNS/TFTP responses from dnsmasq

Daniel P. Berrangé 9b80e0c12a util: drop support for stack traces with logging
The log filters have supported the use of a "+" before the source match
string to request that a stack trace be emitted for every log message:

  commit 548563956e
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Wed May 9 15:18:56 2012 +0100

    Allow stack traces to be included with log messages

    Sometimes it is useful to see the callpath for log messages.
    This change enhances the log filter syntax so that stack traces
    can be show by setting '1:+NAME' instead of '1:NAME'.

With the huge & ever increasing number of logging statements per file,
this will be incredibly verbose and have a major performance penalty.
This makes the feature impractical to use widely and as such it is not
worth the code maint cost.

Removing this seldom used feature allows us to drop the 'execinfo'
module in gnulib which provides the backtrace() function which doesn't
exist on non-Linux.

Users who want to get stack traces of parts of libvirt can use GDB,
or systemtap for live tracing with minimal perf impact.

Julio Faracco 71519d4638 qemu: Generate 'xres' and 'yres' for QEMU video devices
This commit let QEMU command line define 'xres' and 'yres' properties
if XML contains both properties from video model: based on resolution
fields 'x' and 'y'. There is a conditional structure inside
qemuDomainDeviceDefValidateVideo() that validates if video model
supports this feature. This commit includes the necessary changes to
cover resolution for 'video-qxl-resolution' test cases too.

Julio Faracco 7286279797 conf: Add 'x' and 'y' resolution into video XML definition
This commit adds resolution element with parameters 'x' and 'y' into video
XML domain group definition. Both, properties were added into an element
called 'resolution' and it was added inside 'model' element. They are set
as optional. This element does not follow QEMU properties 'xres' and
'yres' format. Both HTML documentation and schema were changed too. This
commit includes a simple test case to cover resolution for QEMU video
models. The new XML format for resolution looks like:

    <model ...>
      <resolution x='800' y='600'/>
    </model>

Cole Robinson fbf7c23c2d qemu: caps: Use unique key for domCaps caching
When searching qemuCaps->domCapsCache for existing domCaps data,
we check for a matching pair of arch+virttype+machine+emulator. However
for the hash table key we only use the machine string. So if the
cache already contains:

  x86_64 + kvm + pc + /usr/bin/qemu-kvm

But a new VM is defined with

  x86_64 + qemu + pc + /usr/bin/qemu-kvm

We correctly fail to find matching cached domCaps, but then attempt
to use a colliding key with virHashAddEntry

Fix this by building a hash key from the 4 values, not just machine

The reason this is being sent separately is because these are not

used, allowing us to erase VIR_FREE() calls that were made inside
the loop and in 'cleanup' labels.

Laine Stump 382c762c45 conf: remove parse code for long-extinct "<state devaddr='d🅱️s'/>
Back in July 2009, in the days before libvirt supported explicitly
assigning a PCI address to every device, code was added to save the
PCI addresses of hotplugged network, disk, and hostdevs in the domain
status with this XML element:

   <state devaddr='domain🚌slot'/>

This was added in commits 4e21a95a, 01654107, in v0.7.0, and 0c5b7b93
in v0.7.1.

Then just a few months later, in November 2009, The code that actually
formatted the "devaddr='blah'" into the status XML was removed by
commit 1b0cce7d3 (which "introduced a standardized data structure for
device addresses"). The code to *parse* the devaddr from the status
was left in for backward compatibility though (it just parses it into
the "standard" PCI address).

At the time the devaddr attribute was added, a few other attributes
already existed in the <state> element for network devices, and these
were removed over time (I haven't checked the exact dates of this),
but 10 years later, in libvirt v5.8.0, we *still* maintain code to
parse <state devaddr='blah'/> from the domain status.

In the meantime, even distros so old that we no longer support them in
upstream libvirt are using a libvirt new enough that it doesn't ever
write <state devaddr='blah'/> to the domain status XML.

Since the only way a current libvirt would ever encounter this element
would be if someone was upgrading directly from libvirt <= v0.7.5 with
running guests, it seems safe to finally remove the code that parses it.

Pavel Mores b5308a1205 qemu: fix EFI nvram removal on domain undefine
When undefining a UEFI domain its nvram file has to be properly handled as
well.  It's mandatory to use one of --nvram and --keep-nvram options when
'virsh undefine <domain>' is issued for a UEFI domain.  To fix the bug as
reported, virsh should return an error message if neither option is used
and the nvram file should be removed when --nvram is given.

The cause of the problem is that when qemuDomainUndefineFlags() is invoked
on an inactive domain the path to its nvram file is empty.  This commit
aims to fix this by formatting and filling in the path in time for the
nvram removal code to run properly.
