      conf: Remove NONNULL(1,2) for virNetDevBandwidthFormat · 5b93aa57
      由 John Ferlan 提交于 
      Since the code checks and handles NULL parameters, remove the NONNULL
from the prototype.

Also fix the comment in the source to reference the right name.

      conf: Remove NONNULL(2) for virNetDevBandwidthParse · 273e71e7
      由 John Ferlan 提交于 
      Since the code checks and handles a NULL 'node' before proceeding
there's no need for the prototype with the NONNULL(2).

      util: Remove NONNULL(1) for virNetDevGetName · 91d28d99
      由 John Ferlan 提交于 
      The 'ifindex' argument is not a pointer, so no need for NONNULL in prototype

      qemu: Always format formatStr for blockdev-snapshot-sync · f2a76a26
      由 John Ferlan 提交于 
      The qemuDomainSnapshotPrepare should always set a > 0 format value anyway,
so remove the check.

Found by Coverity.

      network: reconnect tap devices during networkNotifyActualDevice · 85bcc022
      由 Laine Stump 提交于 
      If a network is destroyed and restarted, or its bridge is changed, any
tap devices that had previously been connected to the bridge will no
longer be connected. As a first step in automating a reconnection of
all tap devices when this happens, this patch modifies
networkNotifyActualDevice() (which is called once for every
<interface> of every active domain whenever libvirtd is restarted) to
reconnect any tap devices that it finds disconnected.

With this patch in place, you will need to restart libvirtd to
reconnect all the taps to their proper bridges. A future patch will
add a callback that hypervisor drivers can register with the network
driver to that the network driver can trigger this behavior
automatically whenever a network is started.

      util: new function virNetDevTapAttachBridge() · a4541349
      由 Laine Stump 提交于 
      This patch splits out the part of virNetDevTapCreateInBridgePort()
that would need to be re-done if an existing tap device had to be
re-attached to a bridge, and puts it into a separate function. This
can be used both when an existing domain interface config is updated
to change its connection, and also to re-attach to the "same" bridge
when a network has been stopped and restarted. So far it is used for
nothing.

      util: new function virNetDevGetMaster() · e75f5bfb
      由 Laine Stump 提交于 
      This function provides the bridge/bond device that the given network
device is attached to. The return value is 0 or -1, and the master
device is a char** argument to the function - this is needed in order
to allow for a "success" return from a device that has no master.

      util: allow retrieving ethtool features when unprivileged · 549fe5a8
      由 Laine Stump 提交于 
      The only reason that the ethtool features weren't being retrieved in
an unprivileged libvirtd was because they required ioctl(), and the
ioctl was using an AF_PACKET socket, which requires root. Now that we
are using AF_UNIX for ioctl(), this restriction can be removed.

      util: use AF_UNIX family (not AF_PACKET) for ioctl sockets · 1c9a8746
      由 Laine Stump 提交于 
      The exact family of the socket created for the fd used by ioctl(7)
doesn't matter, it just needs to be a socket and not a file. But for
some reason when macvtap support was added, it used
AF_PACKET/SOCK_DGRAM sockets for its ioctls; we later used the same
AF_PACKET/SOCK_DGRAM socket for new ioctls we added, and eventually
modified the other pre-existing ioctl sockets (for creating/deleting
bridges) to also use AF_PACKET/SOCK_DGRAM (that code originally used
AF_UNIX/SOCK_STREAM).

The problem with using AF_PACKET (intended for sending/receiving "raw"
packets, i.e. packets that can be some protocol other than TCP or UDP)
is that it requires root privileges. This meant that none of the
ioctls in virnetdev.c or virnetdevip.c would work when running
libvirtd unprivileged.

This packet solves that problem by changing the family to AF_UNIX when
creating the socket used for any ioctl().
