Adding this feature will allow users to easily attach a hostdev network
interface using PCI passthrough.
The interface can be attached using --type=hostdev and PCI address or
as --source. This command also allows you to tell, whether the interface
should be managed.

tests: handle backspace-newline pairs in test input files
all the test argv files were line wrapped so that the args
were less than 80 characters.
The way the line wrapping was done turns out to be quite
undesirable, because it often leaves multiple parameters
on the same line. If we later need to add or remove
individual parameters, then it leaves us having to redo
line wrapping.
This commit changes the line wrapping so that every
single "-param value" is one its own new line. If the
"value" is still too long, then we break on ',' or ':'
or ' ' as needed.
This means that when we come to add / remove parameters
from the test files line, the patch diffs will only
ever show a single line added/removed which will greatly
simplify review work.

Use virNetDevSetupControl instead of open coding using socket(AF_LOCAL...)
and clearing virIfreq.
By using virNetDevSetupControl, the socket is then opened using
AF_PACKET which requires being privileged (effectively root) in
order to complete successfully. Since that's now a requirement,
then the ioctl(SIOCETHTOOL) should not fail with EPERM, thus it
is removed from the filtered listed of failure codes.
Signed-off-by: John Ferlan <jferlan@redhat.com>
Since the SIOCETHTOOL ioctl only works for privileged daemons, if called
when not root, then virNetDevGetFeatures will VIR_DEBUG a message and
return 0 as if the functions were not available for the architecture.
This effectively returns an empty bitmap indicating no features available.

Signed-off-by: John Ferlan <jferlan@redhat.com>
In commit id 'c9027d8f4' when updating the posted patch to generate
a bitmap instead of an array of named feature bits, adjustment of
the args was missed
Recently reverted commit id '6f2a0198' showed a need to add extra
comments when dealing with filtering of potential "non-issues".
Scanning through upstream patch postings indicates early on the
reasons for the filtering of specific ioctl failures were provided;
however, when converted from causing an error to VIR_DEBUG's the
reasons were missing. A future read/change of the code incorrectly
assumed they could or should be removed.
This reverts commit 6f2a0198e9.
This commit removed error reporting from virNetDevSendEthtoolIoctl
pushing responsibility onto the callers. This is wrong, however,
since virNetDevSendEthtoolIoctl calls virNetDevSetupControl
which can still report errors. So as a result virNetDevSendEthtoolIoctl
may or may not report errors depending on which bit of it fails, and as
a result callers now overwrite some errors.
It also introduced a regression causing unprivileged libvirtd to
spew error messages to the console due to inability to query the
NIC features, an error which was previously ignored.

Looking back at the original posting I see no explanation of why
thsi refactoring was needed, so reverting the clearly broken
error reporting logic looks like the best option.

The code reported that a migration flag is unsupported but didn't jump
to the error label. Probably an oversight in commit f88af9dc that
introduced the flag checking.
Since the flag was not enabled when 'eating' the migration cookie,
libvirt reported a bogus error when memory hotplug was enabled:
unsupported migration cookie feature memory-hotplug
The error was ignored though due to a bug in the code so it slipped
through testing.

Commit id '0f7436ca' added virNetDevWaitDadFinish using ATTRIBUTE_NONNULL
for both arguments, although one is a non-null argument. A Coverity build
balks at that.
Rather than "if (virNetDevFeatureAvailable(ifname, &cmd))" change the
success criteria to "if (virNetDevFeatureAvailable(ifname, &cmd) == 1)".
The called helper returns -1 on failure, 0 on not found, and 1 on found.
Thus a failure was setting bits.

values without adjusting its callers

Commit id 'fdda3760' only managed a symptom where it was possible to
create a file in a pool without libvirt's knowledge, so it was reverted.
The real fix is to have all the createVol API's which actually create
a volume (disk, logical, zfs) and the buildVol API's which handle the
real creation of some volume file (fs, rbd, sheepdog) manage deleting
any volume which they create when there is some sort of error in
processing the volume.
This way the onus isn't left up to the storage_driver to determine whether
the buildVol failure was due to some failure as a result of adjustments
made to the volume after creation such as getting sizes, changing ownership,
changing volume protections, etc. or simple a failure in creation.
Without needing to consider that the volume has to be removed, the
buildVol failure path only needs to remove the volume from the pool.
This way if a creation failed due to duplicate name, libvirt wouldn't
remove a volume that it didn't create in the pool target.
This reverts commit fdda37608a.
This commit only manages a symptom of finding a buildRet failure
where a volume was not listed in the pool, but someone created the
volume outside of libvirt in the pool being managed by libvirt.
After successfully returning from virFileOpenAs, if subsequent calls fail,
then we need to remove the file since our caller expects that failures after
creation will remove the created file.
After a successful qemu-img/qcow-create of the backing file, if we
fail to stat the file, change it owner/group, or mode, then the
cleanup path should remove the file.
Currently the code does not handle the NFS root squash environment
properly since if the file gets created, then the subsequent chmod
will fail in a root squash environment where we're creating a file
in the pool with qemu tools, such as seen via:
$ virsh vol-create-from $pool $file.xml file.img --inputpool $pool
assuming $file.xml is creating a file of "<format type='qcow2'"> from
an existing file.img in the pool of "<format type='raw'>".
This patch will utilize the virCommandSetUmask when creating the file
in the NETFS pool. The virCommandSetUmask API was added in commit id
'0e1a1a8c4', which was after the original code was developed in commit
id 'e1f27784' to attempt to handle the root squash environment.
Also, rather than blindly attempting to chmod, check to see if the
st_mode bits from the stat match what we're trying to set and only
make the chmod if they don't.
Also, a slight adjustment to the fallback algorithm to move the
virCommandSetUID/virCommandSetGID inside the if (!filecreated) since
they're only useful if we need to attempt to create the file again.
VIR_DEBUG and VIR_WARN will automatically add a new line to the message,
having "\n" at the end or at the beginning of the message results in
empty lines.
