Make with_packager and with_packager_version default to "no". This way
--without-packager-version (as shorthand for --with-packager(-version)=no)
works correctly too.
Prior to this patch libvirt outputs a line like this when
--with-packager(-version) was not specified
# ./daemon/libvirtd
14:11:15.018: 31796: info : libvirt version: 0.8.8, package: ()
Now the unspecified parts are correctly omitted.

clang had 5 reports against virCommand; three were false positives
(a NULL deref in ProcessIO solved by sa_assert, and two uninitialized
memory operations solved by adding an initializer), but two were real.
* src/util/command.c (virCommandProcessIO): Fix real bug of
possible NULL dereference. Teach clang that buf is never NULL.
(virCommandRun): Teach clang that infd is only ever accessed when
initialized.
The processWatchdogEvent fix is real, although it can only trigger
on OOM, since bad things happen if doCoreDump is called with a NULL
pathname argument. The other fixes silence clang, but aren't a real
bug because virReportErrorHelper tolerates a NULL format string even
though *printf does not.
* src/qemu/qemu_driver.c (processWatchdogEvent): Exit on OOM.
(qemuDomainIsActive, qemuDomainIsPersistent, qemuDomainIsUpdated):
Provide valid message.
The SCSI storage backend leaks a string containing the pathname
for each block device it discovers
* src/storage/storage_backend_scsi.c: Free the device name
When creating the virDomain::snapshots hash table, virGetDomain
wasn't checking if the creation was successful. This would then
lead to failures in the vir*DomainSnapshot functions. Better to
report this error early and make virGetDomain fail if the
snapshots hash couldn't be created.
* src/datatypes.c: report failure to make a hash table
A couple of allocation were not calling virReportOOMError on allocation
errors
* src/util/hash.c: add the needed call in virHashCreate and
virHashAddOrUpdateEntry
"virStorageBackendCreateVols":
"names->next" serves as condition expression for "do...while",
however, "names" was shifted before, it then results in one less
loop, and thus, one less volume will be created for mpath pool,
the patch is to fix it.
* src/storage/storage_backend_mpath.c
clang complained that STREQ(group->controllers[i].mountPoint,...) was
a NULL dereference when i==VIR_CGROUP_CONTROLLER_CPUSET, because it
assumes the worst about virCgroupPathOfController. Marking the
argument const doesn't yet have an effect, per this clang bug:
http://llvm.org/bugs/show_bug.cgi?id=7758
So, we use sa_assert, which was designed to shut up false positives
from tools like clang.
* src/util/cgroup.c (virCgroupMakeGroup): Teach clang that there
is no NULL dereference.
This patch reorders the connlimit and comment match extensions relative to the state match (-m state); connlimit being most useful if found after a -m state --state NEW and not before it.
When formatting XML for smartcard device with mode=host, libvirt
generates invalid XML if the device has address info associated:
<smartcard mode='host' <address type='ccid' controller='0' slot='1'/>
Commit 9962e406c6 introduced a
problem where if the VM failed to startup, it would not be
correctly cleaned up. Amongst other things the SELinux
security label would not be removed, which prevents the VM
from ever starting again.
The virDomainIsActive() check at the start of qemudShutdownVMDaemon
checks for vm->def->id not being -1. By moving the assignment of the
VM id to the start of qemudStartVMDaemon, we can ensure cleanup will
occur on failure
* src/qemu/qemu_driver.c: Move initialization of 'vm->def->id'
so that qemudShutdownVMDaemon() will process the shutdown
Compilation on mingw was warning about %lld use in fprintf, and
in the gnulib strptime module about dead labels.
* tools/virsh.c (vshPrint): Change redirect.
(vshPrintExtra): Allow use within vshPrint. Avoid fprintf on
arbitrary formats, since we aren't using gnulib module; instead,
use virVasprintf to pre-format.
(vshError): Likewise.
* .gnulib: Update to latest, for mingw strptime warning fix.
Reported by Matthias Bolte.
Introduced by commit fac97c65c distributing cfg.mk, which
previously could blindly assume it was in a git checkout.
* cfg.mk (_update_required): Also check for .git.
* autogen.sh: Don't run bootstrap from a tarball.
Reported by Daniel Veillard.
When attaching a device that already exists, xend driver updates
the device with "device_configure", it causes problems (e.g. for
disk device, 'device_configure' only can be used to update device
like CDROM), on the other hand, we provide additional API
(virDomainUpdateDevice) to update device, this fix is to raise up
errors instead of updating the existed device which is not CDROM
device.
Changes from v1 to v2:
- allow to update CDROM
* src/xen/xend_internal.c
Building the 0.8.8 release candidate on cygwin produced this compiler
warning, which is indicative of catastrophic failure on any attempt to
print an error message with errno turned to a string:
CC strerror_r.lo
strerror_r.c: In function 'rpl_strerror_r':
strerror_r.c:67: warning: assignment makes integer from pointer without a cast
This has been fixed in gnulib.
* .gnulib: Update to latest, for strerror_r fix.
* src/util/memory.c (includes): Satisfy 'make syntax-check'.
Suspending a VM which contains shell meta characters doesn't work with
libvirt-0.8.7:
/var/log/libvirt/qemu/andreas_231-ne\ doch\ nicht.log:
sh: -c: line 0: syntax error near unexpected token `doch'
sh: -c: line 0: `cat | { dd bs=4096 seek=1 if=/dev/null && dd bs=1048576; }
Although target="andreas_231-ne doch nicht" contains shell meta
characters (here: blanks), they are not properly escaped by
src/qemu/qemu_monitor_{json,text}.c#qemuMonitor{JSON,Text}MigrateToFile()
First, the filename needs to be properly escaped for the shell, than
this command line has to be properly escaped for qemu again.
For this to work, remove the old qemuMonitorEscapeArg() wrapper, rename
qemuMonitorEscape() to it removing the handling for shell=TRUE, and
implement a new qemuMonitorEscapeShell() returning strings using single
quotes.
Using double quotes or escaping special shell characters with backslashes
would also be possible, but the set of special characters heavily
depends on the concrete shell (dsh, bash, zsh) and its setting (history
expansion, interactive use, ...)

The logging functions are enhanced so that immediately prior to
the first log message being printed to any output channel, the
libvirt package version will be printed.
eg
$ LIBVIRT_DEBUG=1 virsh
18:13:28.013: 17536: info : libvirt version: 0.8.7
18:13:28.013: 17536: debug : virInitialize:361 : register drivers
...
The 'configure' script gains two new arguments which can be
used as
--with-packager="Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10"
--with-packager-version="1.fc14"
to allow distros to append a custom string with package specific
data.
The RPM specfile is modified so that it appends the RPM version,
the build host, the build date and the packager name.
eg
$ LIBVIRT_DEBUG=1 virsh
18:14:52.086: 17551: info : libvirt version: 0.8.7, package: 1.fc13 (Fedora Project, x86-01.phx2.fedoraproject.org, 01-27-2011-18:00:10)
18:14:52.086: 17551: debug : virInitialize:361 : register drivers
Thus when distro packagers receive bug reports they can clearly
see what version was in use, even if the bug reporter mistakenly
or intentionally lies about version/builds
* src/util/logging.c: Output version data prior to first log message
* libvirt.spec.in: Include RPM release, date, hostname & packager
* configure.ac: Add --with-packager & --with-packager-version args
QEMUD_CMD_FLAG_PCI_MULTIBUS should be set in the function
qemuCapsExtractVersionInfo()
The flag QEMUD_CMD_FLAG_PCI_MULTIBUS is used in the function
qemuBuildDeviceAddressStr(). All callers get qemuCmdFlags
by the function qemuCapsExtractVersionInfo() except that
testCompareXMLToArgvFiles() in qemuxml2argvtest.c.
So we should set QEMUD_CMD_FLAG_PCI_MULTIBUS in the function
qemuCapsExtractVersionInfo() instead of qemuBuildCommandLine()
because the function qemuBuildCommandLine() does not be called
when we attach a pci device.
tests: set QEMUD_CMD_FLAG_PCI_MULTIBUS in testCompareXMLToArgvFiles()
set QEMUD_CMD_FLAG_PCI_MULTIBUS before calling qemuBuildCommandLine()
as the flags is not set by qemuCapsExtractVersionInfo().

Win32 doesn't have a concept of signal masks so disable that
code. It is unclear how SIGINT is delivered (if at all) on
Win32, so this might further work to provide an alternative
to pthread_sigmask
* tools/virsh.c: Avoid pthread_sigmask on Win32
Quite a few hosts don't have cgroups mounted and so see warnings
from libvirt logged, which then cause bug reports, etc. Reduce
the log level to INFO so they're not visible by default
* src/qemu/qemu_driver.c: Reduce log level for cgroups
When run non-root the nwfilter driver logs error messages about
being unable to find iptables/ebtables commands (they are in
/sbin which isn't in $PATH). The nwfilter driver can't ever work
as non-root, so simply skip it entirely thus avoiding the error
messages
* src/conf/nwfilter_conf.h, src/nwfilter/nwfilter_driver.c,
src/nwfilter/nwfilter_gentech_driver.c,
src/nwfilter/nwfilter_gentech_driver.h: Pass 'bool privileged'
flag down to final driver impl
* src/nwfilter/nwfilter_ebiptables_driver.c: Skip initialization

A typo s/spice/vnc/ caused parsing of the spice 'auth' data
to write into the wrong part of the struct, blowing away
other unrelated data.
* src/conf/domain_conf.c: s/vnc/spice/ in parsing spice auth
Most of te VIR_INFO calls in the udev driver are only relevant
to developers so can switch to VIR_DEBUG. Failure to initialize
libpciaccess though is a fatal error
* src/node_device/node_device_udev.c: Adjust log levels
When probing machine types if the QEMU binary does not exist
we get a hard to diagnose error, due to the execve() in the
child failing
error: internal error Child process exited with status 1.
Add an explicit check so that we get
error: Cannot find QEMU binary /usr/libexec/qem3u-kvm: No such file or directory
* src/qemu/qemu_capabilities.c: Check for QEMU binary
To make it easier to investigate problems with async event
delivery, add two more debugging lines
* daemon/remote.c: Debug when an event is queued for dispatch
* src/remote/remote_driver.c: Debug when an event is received
for processing
When built as modules, the connection drivers live
in $LIBDIR/libvirt/drivers. Now we add lock manager
drivers, we need to distinguish. So move the existing
modules to 'connection-driver'
* src/Makefile.am: Move module install dir
* src/driver.c: Move module search dir
Some functionality run in virExec hooks may do I/O which
can trigger SIGPIPE. Renable SIGPIPE blocking around the
hook function
* src/util/util.c: Block SIGPIPE around hooks
The Linux kernel headers don't have a value for SCSI type 12,
but HAL source code shows this to be a 'raid'. Add workaround
for this type. Lower log level for unknown types since
this is not a fatal error condition. Include the device sysfs
path in the log output to allow identification of which device
has problems.
* src/node_device/node_device_udev.c: Add SCSI RAID type
libpciaccess has many bugs in its pci_system_init/cleanup
functions that makes calling them multiple times unwise.
eg it will double close() FDs, and leak other FDs.
* src/node_device/node_device_udev.c: Only initialize
libpciaccess once
