libvirt-guests init script should be started as late as possible during
host startup and stopped as early as possible during host shutdown to
make sure required services are already/still up and running at the time
libvirt-guests runs.
The addrToString methods were not coping with UNIX domain sockets
which have no normal host+port address. Hardcode special handling
for these so that SASL routines can work over UNIX sockets. Also
fix up SSF logic in remote client so that it presumes that a UNIX
socket is secure
* daemon/remote.c: Fix addrToString for UNIX sockets.
* src/remote/remote_driver.c: Fix addrToString for UNIX sockets
and fix SSF logic to work for TLS + UNIX sockets in the same
manner
Refactor some daemon code to facilitate the introductioin of static
probes, sanitizing function exit paths in many places
* daemon/libvirtd.c: Pass the dname string into remoteCheckDN
to let caller deal with failure paths. Add separate exit paths
to remoteCheckCertificate for auth failure vs denial. Merge
all exit paths in qemudDispatchServer to one cleanup block
* daemon/remote.c: Add separate exit paths to SASL & PolicyKit
functions for auth failure vs denial
Before this patch, the testsuite was noisy:
TEST: qemuargv2xmltest
........................................ 40
................20:41:28.046: warning : qemuParseCommandLine:6565 : unknown QEMU argument '-unknown', adding to the qemu namespace
20:41:28.046: warning : qemuParseCommandLine:6565 : unknown QEMU argument 'parameter', adding to the qemu namespace
. 57 OK
PASS: qemuargv2xmltest
It's not a real failure (which is why the test was completing
successfully), so much as an intentional warning to the user that use
of the qemu namespace has the potential for undefined effects that
leaked through the default logging behavior. After this patch series,
all tests can access any logged data, and this particular test can
explicitly check for the presence or absence of the warning, such that
the test output becomes:
TEST: qemuargv2xmltest
........................................ 40
................. 57 OK
PASS: qemuargv2xmltest
* tests/testutils.h (virtTestLogContentAndReset): New prototype.
* tests/testutils.c (struct virtTestLogData): New struct.
(virtTestLogOutput, virtTestLogClose, virtTestLogContentAndReset):
New functions.
(virtTestMain): Always capture log data emitted during tests.
* tests/qemuargv2xmltest.c (testCompareXMLToArgvHelper, mymain):
Use flag to mark which tests expect noisy stderr.
(testCompareXMLToArgvFiles): Add parameter to test whether stderr
was appropriately silent.
Tweaked the PolicyKit documentation improvement patch submitted
by Patrick Dignan.
Additionally, removed the reference to PolicyKit.conf, which is
no longer used by PolicyKit, plus added a link to the expanded
PolicyKit example page on the wiki.
I got tired of seeing this.
config.status: executing libtool commands
/bin/rm: cannot remove `libtoolT': No such file or directory
config.status: executing po-directories commands
While I was at it, there were a couple other unused variables.
* configure.ac (RM, MV, TAR): Drop; nothing in libvirt directly uses
this, and assigning RM interferes with libtool.
When nwfilter support was added to UML, I didn't realise the UML driver
needed instrumentation to make updating nwfilters on the fly work. This
patch adds this bit of glue.

cmdAttachInterface and cmdAttachDisk still used vshRealloc and sprintf
for generating XML, which is hardly maintainable. Let's get rid of this
old code.
* src/Makefile.am (libvirt.def, libvirt_qemu.def): '\}' and '\t'
are not required by POSIX. Use '}' and literal tab instead.
(install-data-local): Avoid sed -i.
* tests/read-bufsiz: Likewise.

Added a workable initial page for the libvirt Application
Development Guide, giving the online viewable options +
the available download ones (pdf, epub, srpm).
Added a link to the PDF to the main Downloads page, plus
neatened the html tags throughout the page as they
were a bit of a mess.
Added --enable-compile-warnings=error to the autogen line,
as suggested by Eric Blake.
The current code will go into an infinite loop if the printf generated
string is >= 1000, AND exactly 1 character smaller than the amount of free
space in the buffer. When this happens, we are dropped into the loop body,
but nothing will actually change, because count == (buf->size - buf->use - 1),
and virBufferGrow returns unchanged if count < (buf->size - buf->use)
Fix this by removing the '- 1' bit from 'size'. The *nprintf functions handle
the NULL byte for us anyways, so we shouldn't need to manually accommodate
for it.
Here's a bug where we are actually hitting this issue:
https://bugzilla.redhat.com/show_bug.cgi?id=602772
v2: Eric's improvements: while -> if (), remove extra va_list variable,
make sure we report buffer error if snprintf fails
v3: Add tests/virbuftest which reproduces the infinite loop before this
patch, works correctly after
Apparently the xen block device statistics moved from
"/sys/devices/xen-backend/vbd-%d-%d/statistics/%s"
to
"/sys/bus/xen-backend/devices/vbd-%d-%d/statistics/%s"
* src/xen/block_stats.c: try the extra path in case of failure to
find the statistics in /sys
Unless --driver tap|file option was given to attach-disk, virsh would
generate <disk type='block'> XML which might be fine for Xen but not for
other hypervisors. This patch introduces a new option --sourcetype which
can be used to explicitly set the type of disk source. The option
accepts either "file" or "block" types.
Very occasionally during a parallel make, dispatch.c would
be compiled before the generated remote headers had been
fully written. This would cause it to compile an empty
union, and result in really wierd runtime bugs that are
near impossible to diagnose.
* daemon/Makefile.am: Fix remote build deps
If the remote daemon args/ret unions ever become zero length
(due to a build / Makefile bug) then bad stuff happens at
runtime. Add a compile time assertion to check for this kind
of problem
* daemon/remote.h: Ensure non-zero length unions
A QEMU guest can have upto VIR_DOMAIN_BOOT_LAST boot entries
defined. When building the QEMU arg, each entry takes a
single byte. This means the array must be declared to be
VIR_DOMAIN_BOOT_LAST+1 bytes in length to allow for the
trailing null
* src/qemu/qemu_conf.c: Fix off-by-1 boot arg array size
For static-only DHCP, i.e. with no <range> but at least one <host>
element within <dhcp> element, we have to add "--dhcp-range IP,static"
option to dnsmasq to actually enable the service. Without this option,
dnsmasq will not respond to DHCP requests.

Before this commit SessionIsActive was not used because ESX(i)
doesn't implement it. vCenter supports SessionIsActive, so use
it here, but keep the fall back mechanism for ESX(i) and GSX.
QueryVirtualDiskUuid is only available on an ESX(i) server. vCenter
returns an NotImplemented fault and a GSX server is missing the
VirtualDiskManager completely. Therefore only use QueryVirtualDiskUuid
with an ESX(i) server and fall back to path as storage volume key for
vCenter and GSX server.
VirtualDisks are .vmdk file based. Other files in a datastore
like .iso or .flp files don't have a UUID attached, fall back
to the path as key for them.
This patch adds support for ethernet interface type to OpenVZ domains
as stated in this previous message: http://www.redhat.com/archives/libvir-
list/2010-July/msg00658.html
Instead of splitting the path part of a datastore path into
directory and file name, keep this in one piece. An example:
"[datastore] directory/file"
was split into this before:
datastoreName = "datastore"
directoryName = "directory"
fileName = "file"
Now it's split into this:
datastoreName = "datastore"
directoryName = "directory"
directoryAndFileName = "directory/file"
This simplifies code using esxUtil_ParseDatastorePath, because
directoryAndFileName is used more often than fileName. Also the
old approach expected the datastore path to reference an actual
file, but this isn't always correct, especially when listing
volumes. In that case esxUtil_ParseDatastorePath is used to parse
a path that references a directory. This fails for a vpx://
connection because the vCenter returns directory paths with a
trailing '/'. The new approach is robust against this and the
actual decision if the datastore path should reference a file or
a directory is up to the caller of esxUtil_ParseDatastorePath.
Update the tests accordingly.
snprintf is currently implicitly picked up by getaddrinfo, but we
might as well make it explicit so that mingw doesn't break if
getaddrinfo changes to drop the dependency.
func doesn't matter for gcc compilation, but may help other compilers
cope with our use of __func__.
* bootstrap.conf (gnulib_modules): Add snprintf and func.
