commit 09778e09 switched from using ioctl(SIOCBRDELBR) for bridge
device deletion to using a netlink RTM_DELLINK message, which is the
more modern way to delete a bridge (and also doesn't require the
bridge to be ~IFF_UP to succeed). However, although older kernels
(e.g. 2.6.32, in RHEL6/CentOS6) support deleting *some* link types
with RTM_NEWLINK, they don't support deleting bridges, and there is no
compile-time way to figure this out.
This patch moves the body of the SIOCBRDELBR version of
virNetDevBridgeDelete() into a static function, calls the new function
from the original, and also calls the new function from the
RTM_DELLINK version if the RTM_DELLINK message generates an EOPNOTSUPP
error. Since RTM_DELLINK is done from the subordinate function
virNetlinkDelLink, which is also called for other purposes (deleting a
macvtap interface), a function pointer called "fallback" has been
added to the arglist of virNetlinkDelLink() - if that arg != NULL, the
provided function will be called when (and only when) RTM_DELLINK
fails with EOPNOTSUPP.

When we set the MAC address of a network device as a part of setting
up macvtap "passthrough" mode (where the domain has an emulated netdev
connected to a host macvtap device that has exclusive use of the
physical device, and sets the device MAC address to match its own,
i.e. "<interface type='direct'> <source mode='passthrough' .../>"), we
use ioctl(SIOCSIFHWADDR) giving it the name of that device. This is
true even if it is an SRIOV Virtual Function (VF).
But, when we are setting the MAC address / vlan ID of a VF in
preparation for "hostdev network" passthrough (this is where we set
the MAC address and vlan id of the VF after detaching the host net
driver and before assigning the device to the domain with PCI
passthrough, i.e. "<interface type='hostdev'>", we do the setting via
a netlink RTM_SETLINK message for that VF's Physical Function (PF),
telling it the VF# we want to change. This sets an "administratively
changed MAC" flag for that VF in the PF's driver, and from that point
on (until the PF driver is reloaded, *not* merely the VF driver) that
VF's MAC address can't be changed using ioctl(SIOCSIFHWADDR) - the
only way to change it is via the PF with RTM_SETLINK.
This means that if a VF is used for hostdev passthrough, it will have
the admin flag set, and future attempts to use that VF for macvtap
passthrough will fail.
The solution to this problem is to check if the device being used for
macvtap passthrough is actually a VF; if so, we use the netlink
RTM_SETLINK message to the PF to set the VF's mac address instead of
ioctl(SIOCSIFHWADDR) directly to the VF; if not, behavior does not
change from previously.
There are three pieces to making this work:
1) virNetDevMacVLan(Create|Delete)WithVPortProfile() now call
virNetDev(Replace|Restore)NetConfig() rather than
virNetDev(Replace|Restore)MacAddress() (simply passing -1 for VF#
and vlanid).
2) virNetDev(Replace|Restore)NetConfig() check to see if the device is
a VF. If so, they find the PF's name and VF#, allowing them to call
virNetDev(Replace|Restore)VfConfig().
3) To prevent mixups when detaching a macvtap passthrough device that
had been attached while running an older version of libvirt,
virNetDevRestoreVfConfig() is potentially given the preserved name
of the VF, and if the proper statefile for a VF can't be found in
the stateDir (${stateDir}/${pfname}_vf${vfid}),
virNetDevRestoreMacAddress() is called instead (which will look in
the file named ${stateDir}/${vfname}).
This problem has existed in every version of libvirt that has both
macvtap passthrough and interface type='hostdev'. Fortunately people
seem to use one or the other though, so it hasn't caused any real
world problem reports.
Throughout the code, we have several places need to construct a path
somewhere in /sys/class/net/... They are not consistent and nearly
each code piece invents its own way how to do it. So unify this by:
1) use virNetDevSysfsFile() wherever possible
2) At least use common macro SYSFS_NET_DIR declared in virnetdev.h at
the rest of places which can't go with 1)

These two functions are identical, so no sense in having the
duplication. I resisted the temptation to replace calls to
virNetDevMacVLanDelete() with calls to virNetlinkDelLink() just in
case some mythical future platform has macvtap devices that aren't
managed with netlink (or in case we some day need to do more than just
tell the kernel to delete the device).
Investigation of a problem with creating passthrough macvtap devices
(https://bugzilla.redhat.com/show_bug.cgi?id=1185501) has shown that
this slightly more verbose failure message is useful. In particular,
the mac address can be used to determine the domain. You could also
figure this out by looking at preceding messages in a debug log, but
this gets it in a single place.
When compiling without WITH_MACVTAP, we can get:
'unsupported flags (0x1) in function
virNetDevMacVLanCreateWithVPortProfile'
on an attempt to start a domain.
Remove the flag check to reach the more helpful error:
Cannot create macvlan devices on this platform

Currently, MAC registration occurs during device creation, which is
early enough that, during live migration, you end up with duplicate
MAC addresses on still-running source and target devices, even though
the target device isn't actually being used yet.
This patch proposes to defer MAC registration until right before
the guest can actually use the device -- In other words, right
before starting guest CPUs.

The source code base needs to be adapted as well. Some files
include virutil.h just for the string related functions (here,
the include is substituted to match the new file), some include
virutil.h without any need (here, the include is removed), and
some require both.
The virNetlinkCommand() method takes an 'unsigned char **'
parameter to be filled with the received netlink message.
The callers then immediately cast this to 'struct nlmsghdr',
triggering (bogus) warnings about increasing alignment
requirements
util/virnetdev.c: In function 'virNetDevLinkDump':
util/virnetdev.c:1300:12: warning: cast increases required alignment of target type [-Wcast-align]

Since all callers cast to 'struct nlmsghdr' we can avoid
the warning problem entirely by simply changing the
signature of virNetlinkCommand to return a 'struct nlmsghdr **'
instead of 'unsigned char **'. The way we do the cast inside
virNetlinkCommand does not have any alignment issues.

Currently, after we removed the qemu driver lock, it may happen
that two or more threads will start up a machine with macvlan and
race over virNetDevMacVLanCreateWithVPortProfile(). However,
there's a racy section in which we are generating a sequence of
possible device names and detecting if they exits. If we found
one which doesn't we try to create a device with that name.
However, the other thread is doing just the same. Assume it will
succeed and we must therefore fail. If this happens more than 5
times (which in massive parallel startup surely will) we return
-1 without any error reported. This patch is a simple hack to
both of these problems. It introduces a mutex, so only one thread
will enter the section, and if it runs out of possibilities,
error is reported. Moreover, the number of retries is raised to 20.
These classes can borrow unused bandwidth. Basically,
only egress qdsics can have classes, therefore we can
do this kind of traffic shaping only on host's outgoing,
that is domain's incoming traffic.
When failing to create a macvlan interface, make sure the
error message contains the name of the host interface

Until now, virNetlinkCommand has assumed that the nl_pid in the source
address of outgoing netlink messages should always be the return value
of getpid(). In most cases it actually doesn't matter, but in the case
of communication with lldpad, lldpad saves this info and later uses it
to send netlink messages back to libvirt. A recent patch to fix Bug
816465 changed the order of the universe such that the netlink event
service socket is no longer bound with nl_pid == getpid(), so lldpad
could no longer send unsolicited messages to libvirtd. Adding src_pid
as an argument to virNetlinkCommand() is the first step in notifying
lldpad of the proper address of the netlink event service socket.

There are several functions that call virNetlinkCommand, and they all
follow a common pattern, with three exit labels: err_exit (or
cleanup), malformed_resp, and buffer_too_small. All three of these
labels do their own cleanup and have their own return. However, the
malformed_resp label usually frees the same items as the
cleanup/err_exit label, and the buffer_too_small label just doesn't
free recvbuf (because it's known to always be NULL at the time we goto
buffer_too_small.
In order to simplify and standardize the code, I've made the following
changes to all of these functions:
1) err_exit is replaced with the more libvirt-ish "cleanup", which
makes sense because in all cases this code is also executed in the
case of success, so labelling it err_exit may be confusing.
2) rc is initialized to -1, and set to 0 just before the cleanup
label. Any code that currently sets rc = -1 is made to instead goto
cleanup.
3) malformed_resp and buffer_too_small just log their error and goto
cleanup. This gives us a single return path, and a single place to
free up resources.
4) In one instance, rather then logging an error immediately, a char*
msg was pointed to an error string, then goto cleanup (and cleanup
would log an error if msg != NULL). It takes no more lines of code
to just log the message as we encounter it.
This patch should have 0 functional effects.
This patch includes the following changes to virnetdevmacvlan.c and

For 802.1Qbh devices, the port profile calls can use a vf argument if
passed by the caller. If the vf argument is -1 it will try to derive the vf
if the device passed is a virtual function.
For 802.1Qbg devices, This patch introduces a null check for the device
argument because during port profile assignment on a hostdev, this argument
can be null.

the interface actually *has* a virtPortProfile, otherwise the event

- if it's NULL, this triggers a segv.
This patch just qualifies the code that adds the client - if
virtPortProfile is NULL, it's skipped.
