94f8205359 linuxNodeGetCPUStats: Correctly handle cpu prefix
To retrieve node cpu statistics on Linux system, the
linuxNodeGetCPUstats function simply uses STRPREFIX() to match the cpuid
with the one read from /proc/stat. However, as the file is read line by
line it may happen, that some CPUs share the same prefix. So if user
requested stats for the first CPU, which is offline, then there's no
cpu1 in the stats file so the one that we match is cpu10. Which is
obviously wrong. Fortunately, the IDs are terminated by a space, so we
can utilize that.

9d6f26e57c Honour prefix in wireshark install dir
Trying to run

  $ ./configure --prefix=$HOME/usr/libvirt-git
  $ make install

results in libvirt trying to install in /usr/lib/wireshark/plugins/....
with predictable amounts of fail. The configure script should not be
hardcoding /usr/lib by default but rather honour $libdir

3d1e9e4779 qemu: snapshot: Forbid snapshots when backing is a scsi passthrough disk
https://bugzilla.redhat.com/show_bug.cgi?id=1034993

SCSI passthrough disks (<disk .. device="lun">) can't be used as backing
for snapshots. Currently with upstream qemu the vm crashes on such
attempt.

This patch adds a early check to catch an attempt to do such a snapshot
and rejects it right away. qemu will fix the issue but this will let us
control the error message.

00e9d6071b build: add $(prefix) to SYSTEMD_UNIT_DIR
I noticed this problem when adding systemd support to netcf, because I
setup the configure.ac to automatically prefer using systemd over
initscripts when possible - although I had copied the
install-data-local target from the example of libvirt's
"libvirt-guests" service more or less verbatim, "make distcheck" would
fail because it was trying to install the service file directly into
/lib/systemd/system rather than into
/home/user/some/unimportant/name/lib/systemd/system.

This is caused by the install/uninstall rules for the systemd unit
files relying on $(DESTDIR) pointing the installed files to the right
place, but in reality $(DESTDIR) is empty during this part of make
distcheck - it instead sets $(prefix) with the toplevel directory used
for its test build/install/uninstall cycle.

(This problem hasn't been seen when running "make distcheck" in
libvirt because libvirt will never build/install systemd support
unless explicitly told to do so on the configure commandline, and
"make distcheck" doesn't put the "--with-initscript=..." option on the
configure commandline.)

I verified that the same problem does exist in libvirt by modifying
libvirt's configure.ac to set:

  init_systemd=yes
  with_init_script=systemd+redhat

This forces a build/install of the systemd unit files during
distcheck, which yields an error like this:

/usr/bin/install -c -m 644 virtlockd.service \
  /lib/systemd/system/
libtool: install: warning: relinking `libvirt-qemu.la'
/usr/bin/install: cannot remove '/lib/systemd/system/virtlockd.service': Permission denied
make[4]: *** [install-systemd] Error 1

After adding $(prefix) to all the definitions of SYSTEMD_UNIT_DIR,
make distcheck now completes successfully with the modified
configure.ac, and the above lines change to something like this:

/usr/bin/install -c -m 644 virtlockd.service \
  /home/laine/devel/libvirt/libvirt-1.2.1/_inst/lib/systemd/system/

55bbb011b9 qemu: snapshot: Avoid libvirtd crash when qemu crashes while snapshotting
We shouldn't access the domain definition while we are in the monitor
section as the domain is unlocked. Additionally after we exit from the
monitor we need to check if the VM is still alive. Not doing so resulted
in a crash if qemu exits while attempting to do an external VM snapshot.

08d07e5fd8 spice: expose the QEMU disable file transfer option
spice-server offers an API to disable file transfer messages
on the agent channel between the client and the guest.
This is supported in qemu through the disable-agent-file-xfer option.

This patch exposes this option to libvirt.
Adds a new element 'filetransfer', with one property,
'enable', which accepts a boolean.
Default is enabled, for backward compatibility.

d8ab981bdd pci: Fix failure paths in detach
https://bugzilla.redhat.com/show_bug.cgi?id=1046919

Since commit v0.9.0-47-g4e8969e (released in 0.9.1) some failures during
device detach were reported to callers of virPCIDeviceBindToStub as
success. For example, even though a device seemed to be detached

    virsh # nodedev-detach pci_0000_07_05_0 --driver vfio
    Device pci_0000_07_05_0 detached

one could find similar message in libvirt logs:

    Failed to bind PCI device '0000:07:05.0' to vfio-pci: No such device

This patch fixes these paths and also avoids overwriting real errors
with errors encountered during a cleanup phase.

didn't do so. Thus callers could not distinguish unbound devices from

d1fdecb624 virSecuritySELinuxSetFileconHelper: Don't fail on read-only NFS
https://bugzilla.redhat.com/show_bug.cgi?id=996543

When starting up a domain, the SELinux labeling is done depending on
current configuration. If the labeling fails we check for possible
causes, as not all labeling failures are fatal. For example, if the
labeled file is on NFS which lacks SELinux support, the file can still
be readable to qemu process. These cases are distinguished by the errno
code: NFS without SELinux support returns EOPNOTSUPP. However, we were
missing one scenario. In case there's a read-only disk on a read-only
NFS (and possibly any FS) and the labeling is just optional (not
explicitly requested in the XML) there's no need to make the labeling
error fatal. In other words, read-only file on read-only NFS can fail to
be labeled, but be readable at the same time.

25221a1b21 maint: avoid nested use of virConnect{Ref,Close}
The public virConnectRef and virConnectClose API are just thin
wrappers around virObjectRef/virObjectRef, with added object
validation and an error reset.  Within our backend drivers, use
of the object validation is just an inefficiency since we always
pass valid objects.  More important to think about is what
happens with the error reset; our uses of virConnectRef happened
to be safe (since we hadn't encountered any earlier errors), but
in several cases the use of virConnectClose could lose a real
error.

Ideally, we should also avoid calling virConnectOpen() from
within backend drivers - but that is a known situation that
needs much more design work.

c05aebfd65 maint: don't leave garbage on early API exit
Several APIs clear out a user input buffer before attempting to
populate it; but in a few cases we missed this memset if we
detect a reason for an early exit.  Note that these APIs
check for non-NULL arguments, and exit early with an error
message when NULL is passed in; which means that we must be
careful to avoid a NULL deref in order to get to that error
message.  Also, we were inconsistent on the use of
sizeof(virType) vs. sizeof(expression); the latter is more
robust if we ever change the type of the expression (although
such action is unlikely since these types are part of our
public API).

f9f5634053 event: filter global events by domain:getattr ACL [CVE-2014-0028]
Ever since ACL filtering was added in commit 7639736 (v1.1.1), a
user could still use event registration to obtain access to a
domain that they could not normally access via virDomainLookup*
or virConnectListAllDomains and friends.  We already have the
framework in the RPC generator for creating the filter, and
previous cleanup patches got us to the point that we can now
wire the filter through the entire object event stack.

Furthermore, whether or not domain:getattr is honored, use of
global events is a form of obtaining a list of networks, which
is covered by connect:search_domains added in a93cd08 (v1.1.0).
Ideally, we'd have a way to enforce connect:search_domains when
doing global registrations while omitting that check on a
per-domain registration.  But this patch just unconditionally
requires connect:search_domains, even when no list could be
obtained, based on the following observations:
1. Administrators are unlikely to grant domain:getattr for one
or all domains while still denying connect:search_domains - a
user that is able to manage domains will want to be able to
manage them efficiently, but efficient management includes being
able to list the domains they can access.  The idea of denying
connect:search_domains while still granting access to individual
domains is therefore not adding any real security, but just
serves as a layer of obscurity to annoy the end user.
2. In the current implementation, domain events are filtered
on the client; the server has no idea if a domain filter was
requested, and must therefore assume that all domain event
requests are global.  Even if we fix the RPC protocol to
allow for server-side filtering for newer client/server combos,
making the connect:serach_domains ACL check conditional on
whether the domain argument was NULL won't benefit older clients.
Therefore, we choose to document that connect:search_domains
is a pre-requisite to any domain event management.

Network events need the same treatment, with the obvious
change of using connect:search_networks and network:getattr.
