remoteDeserializeTypedParameters can now be called with either
preallocated params array (size of which is announced by nparams) or it
can allocate params array according to the number of parameters received
from the server.
Refactored the interface device type identification to make it more
clear about the operations. Add support for udev devtype to detect
VLANs on Linux 3.7 and newer. Move VLAN detection based on device
name to fallback case.
Mechanical move to break up udevIfaceGetIfaceDef() into different
helpers for each of the interface types to hopefully make the code
easier to follow. This moves the vlan code to
udevIfaceGetIfaceDefVlan().
Based on feedback from Laine Stump, improve a number of the error
handling cases to report the issue to the user instead of not generating
data or giving vague errors. Added the bridge device name to every error
message as well to make it clear which bridge failed.

https://bugzilla.redhat.com/show_bug.cgi?id=896685 points out
a regression caused by commit 38c4a9c - libvirt only labels
the backing chain if the backing chain cache is populated, but
the code to populate the cache was only conditionally performed
if cgroup labeling was necessary.
* src/qemu/qemu_cgroup.c (qemuSetupCgroup): Hoist cache setup...
* src/qemu/qemu_process.c (qemuProcessStart): ...earlier into
caller, where it is now unconditional.
To avoid having to hold the qemu driver lock while iterating through
close callbacks and calling them. This fixes a real deadlock when a
domain which is being migrated from another host gets autodestoyed as a
result of broken connection to the other host.
The max value of number of cpus to compute(id) should not
be equal or greater than max cpu number.
The bug ocurrs when id value is equal to max cpu number which
leads to the off-by-one error in the following for loop.
# virsh cpu-stats guest --start 1
error: Failed to virDomainGetCPUStats()
error: internal error cpuacct parse error
Don't allow interval to be > MAX_INT/1000 in virKeepAliveStart()
Guard against possible overflow in virKeepAliveTimeout() by setting the
timeout to be MAX_INT/1000 since the math following will multiply it by 1000.
Currently, if lzop decompression binary produces a warning, it
doesn't exit with zero status but 2 instead. Terrifying, but
true. However, warnings may be ignored using '--ignore-warn'
command line argument. Moreover, in which case, the exit status
will be zero.
For both AttachDevice and UpdateDevice APIs, if the disk device
is 'cdrom' or 'floppy', the operations could be ejecting, updating,
and inserting. For either ejecting or updating, the shared disk
entry of the original disk src has to be removed, because it's
not useful anymore.
And since the original disk def will be changed, new disk def passed
as argument will be free'ed in qemuDomainChangeEjectableMedia, so
we need to copy the orignal disk def before
qemuDomainChangeEjectableMedia, to use it for qemuRemoveSharedDisk.
The disk def could be free'ed by qemuDomainChangeEjectableMedia,
which can thus cause crash if we reference the disk pointer. On
the other hand, we have to remove the added shared disk entry from
the table on error codepath.
The hash entry is changed from "ref" to {ref, @domains}. With this, the
caller can simply call qemuRemoveSharedDisk, without afraid of removing
the entry belongs to other domains. qemuProcessStart will obviously
benifit from it on error codepath (which calls qemuProcessStop to do
the cleanup).
Based on moving various checking into qemuAddSharedDisk, this
avoids the caller using it in wrong ways. Also this adds two
new checking for qemuCheckSharedDisk (disk device not 'lun'
and kernel doesn't support unpriv_sgio simply returns 0).
Automating a sorting check is the only way to ensure we don't
regress. Suggested by Dan Berrange.
* src/check-symsorting.pl (check_sorting): Add a parameter,
validate that groups are in order, and that files exist.
* src/Makefile.am (check-symsorting): Adjust caller.

Due to "feature"/"features" nasty typo, any features marked as mandatory
by one side of a migration are silently considered optional by the other
side. The following is the code that formats mandatory features in
migration cookie:
for (i = 0 ; i < QEMU_MIGRATION_COOKIE_FLAG_LAST ; i++) {
if (mig->flagsMandatory & (1 << i))
virBufferAsprintf(buf, " <feature name='%s'/>\n",
qemuMigrationCookieFlagTypeToString(i));
}
Some functions were using virDomainDeviceInfo where virDevicePCIAddress
would suffice. Some were only using integers for slots and functions,
assuming the bus numbers are always 0.
Switch from virDomainDeviceInfoPtr to virDevicePCIAddressPtr:
qemuPCIAddressAsString
qemuDomainPCIAddressCheckSlot
qemuDomainPCIAddressReserveAddr
qemuDomainPCIAddressReleaseAddr
Switch from int slot to virDevicePCIAddressPtr:
qemuDomainPCIAddressReserveSlot
qemuDomainPCIAddressReleaseSlot
qemuDomainPCIAddressGetNextSlot
Deleted functions (they would take the same parameters
as ReserveAddr/ReleaseAddr do now.)
qemuDomainPCIAddressReserveFunction
qemuDomainPCIAddressReleaseFunction
Recent renames were not reflected into the comments of
libvirt_private.syms; furthermore, since we mix private headers from
several directories into this file, knowing where the file lives
can be helpful.
* src/libvirt_private.sym: Reflect recent names.
We pass over the address/port start/end values many times so we put
them in structs.
