The parameter for the qemuMonitorDeviceDel() is a device alias,
not a device config string. Rename the parameter reflect this
and avoid confusion to readers.
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h,
src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h,
src/qemu/qemu_monitor_text.c, src/qemu/qemu_monitor_text.h:
Rename devicestr to devalias in qemuMonitorDeviceDel()
The QEMU developers have stated that they will not be porting
the commands 'pci_add', 'pci_del', 'usb_add', 'usb_del' to the
JSON mode monitor, since they're obsoleted by 'device_add'
and 'device_del'. libvirt has (untested) code that would have
supported those commands in theory, but since we already use
device_add/del where available, there's no need to keep the
legacy stuff anymore.
The text mode monitor keeps support for all commands for sake
of historical compatability.
* src/qemu/qemu_monitor_json.c: Remove 'pci_add', 'pci_del',
'usb_add', 'usb_del' commands
To ensure that patches in the RPM don't break any functionality
it is neccessary to run the test suites during build. It currently
has 3 tests disabled
- daemon-conf: this is totally broken, since it relies on
being able to resolve the 'libvirt' group & being able to
resolve hostnames at daemon startup. This isn't possible
in a mock build root
- seclabeltest: fails to initialize selinux in the mock
build root. Possibly fixable
- nodeinfotest: broken on s390 + ppc - this is a real bug
* libvirt.spec.in: Add a %check section, with 3 tests
temporarily disabled
The QEMU driver is mistakenly calling directly into the text
mode monitor for the domain memory stats query.
* src/qemu/qemu_driver.c: Replace qemuMonitorTextGetMemoryStats with
qemuMonitorGetMemoryStats
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Add the new
wrapper for qemuMonitorGetMemoryStats
* src/qemu/qemu_monitor_json.c, src/qemu/qemu_monitor_json.h: Add
qemuMonitorJSONGetMemoryStats implementation
Instead of reporting VIR_ERR_INTERNAL_ERROR use the more specific
VIR_ERR_CONFIG_UNSUPPORTED
* src/qemu/qemu_conf.c: Report VIR_ERR_CONFIG_UNSUPPORTED for
unsupported video adapters
To avoid race-conditions, the tear down of a filter has to happen before
the tap interface disappears and another tap interface with the same
name can re-appear. This patch tries to fix this. In one place, where
communication with the qemu monitor may fail, I am only tearing the
filters down after knowing that the function did not fail.
I am also moving the tear down functions into an include file for other
drivers to reuse.
* This patch implements a memory allocator to obtain memory for
structures whose last member is a variable length array. C99 refers
to these variable length objects as structs containing flexible
array members.
* Fixed macro parentheses per Eric Blake
* src/xen/xend_internal.c (xend_parse_sexp_desc_char): Add three
uses of sa_assert, each preceding a strchr(value,... to assure
clang that "value" is non-NULL.
* src/qemu/qemu_driver.c (qemudDomainAttachSCSIDisk):
Initialize "cont" to NULL, so clang knows it's set.
Add an sa_assert so it knows it's non-NULL when dereferenced.
* src/nwfilter/nwfilter_ebiptables_driver.c (ebiptablesApplyNewRules):
Don't dereference a NULL or uninitialized pointer when given
an empty list of rules. Add an sa_assert(inst) in each loop to
tell clang that the uses of "inst[i]" are valid.
* configure.ac (STATIC_ANALYSIS): Define when run via clang's
scan-build or coverity-prevent's cov-build.
Use the CLANG_CC and COVERITY_BUILD_COMMAND envvars as witnesses.
Among some here, there is a strong aversion to the use of "assert", yet
some others think it is essential (when applied judiciously) even --
perhaps "especially" -- at the heart of libraries and core hypervisor-
related code.
Here is a compromise that lets us make assertions about the code (e.g.,
to tell static analyzers about invariants) without even a hint of risk
of an abort.
* src/internal.h [STATIC_ANALYSIS]: Include <assert.h>.
(sa_assert): Define. A no-op most of the time, but equivalent
to classical assert when STATIC_ANALYSIS is nonzero.
* src/storage/storage_backend_fs.c (virStorageBackendFileSystemMount):
Clang was not smart enough, and mistakenly reported that "options"
could be used uninitialized. Initialize it.
Somehow the backend of this function was never implemented in
libvirt's netcf driver, and nobody noticed until now. (The required
netcf function was already in place, so nothing needs to change
there.)
* src/interface/netcf_driver.c: add in the backend function, and point
to it from the table of driver functions.
* src/openvz/openvz_driver.c (openvzGetProcessInfo): Reorganize
so that unexpected /proc/vz/vestat content cannot make us use
uninitialized variables. Without this change, an input line with
a matching "readvps", but fewer than 4 numbers would result in our
using at least "systime" uninitialized.
* tools/virsh.c (vshCommandRun): Test only the initial value of
ctl->timing, so that static analyzers don't have to consider that
it might be changed by cmd->def->handler.
I am getting rid of determining the path to necessary CLI tools at
compile time. Instead, now the firewall driver has an initialization
function that uses virFindFileInPath() to determine the path to
necessary CLI tools and a shutdown function to free allocated memory.
The rest of the patch mostly deals with availability of the CLI tools
and to not call certain code blocks if a tool is not available and that
strings now have to be built slightly differently.
Generate almost all SOAP method mapping code.
Update the driver code to use the complete paramater list of some methods
that had parameters skipped before.
Improve the ESX_VI__METHOD marco to do automatic output deserialization
based on output occurrence. Also incorporate automatic _this binding and
output pointer check.
* src/esx/esx_vmx.c (esxVMX_GatherSCSIControllers): Do not dereference
a NULL disk->driverName. We already detect this condition in another
case. Check for it here, too.
When building libvirt on RHEL-5, I saw this error:
cc1: warnings being treated as errors
openvz/openvz_conf.c: In function 'openvzGetVPSUUID':
openvz/openvz_conf.c:835: warning: 'saveptr' may be used uninitialized in this function
make[3]: *** [libvirt_driver_openvz_la-openvz_conf.lo] Error 1
gcc in RHEL-5 gets upset about this usage of strtok_r (even though
it is perfectly valid). Just set *saveptr to NULL at the
start to quiet it down.

Changes from v1 to v2:
- changed function name prefixes to 'iface' from previous 'Iface'
- Further to make make syntax-check pass:
- indentation fix in interface.h
- added entry to POTFILES.in
I am consolidating network interface related functions used in nwfilter
and macvtap code in utils/interface.c. All function names are prefixed
with 'Iface'. The following functions are now available through
interface.h:
int ifaceCtrl(const char *name, bool up);
int ifaceUp(const char *name);
int ifaceDown(const char *name);
int ifaceCheck(bool reportError, const char *ifname,
const unsigned char *macaddr, int ifindex);
int ifaceGetIndex(bool reportError, const char *ifname, int *ifindex);
I added 'int ifindex' as parameter to ifaceCheck to the original
function and modified the code accordingly.
The nodeinfotest was reliant on the host NUMA topology, but all
the test data files assumed 1 single NUMA node. This test thus
failed on any NUMA machine with > 1 node
* tests/nodeinfotest.c: Hardcode 1 single numa node
With Eric Blake's spelling corrections applied.
Unfortunately after the 0.8.0 release, but here's a beginning of the
documentation of the nwfilter functionality.
* configure.ac docs/news.html.in libvirt.spec.in src/libvirt_public.syms:
updates for release of 0.8.0
* po/*.po po/libvirt.pot: updated a lar set of localizations, and merge
the messages
I mistakenly took the op field in the DHCP message as the DHCP_OFFER
type. Rather than basing the decision to read the VM's IP address on
that field, process the appended DHCP options where option 53 indicates
the actual type of the packet. I am also reading the broadcast address
of the VM, but don't use it so far.
In a couple of cases typos meant we were firing the wrong type
of event. In the python code my previous commit accidentally
missed some chunks of the code.
* python/libvirt-override-virConnect.py: Add missing python glue
accidentally left out of previous commit
* src/conf/domain_event.c, src/qemu/qemu_monitor_json.c: Fix typos
in event name / method name to invoke
