• d0e5d8328   net: xen-netback: correctly restart Tx after a VM restore/migrate ... Browse Code »

  If a VM is saved and restored (or migrated) the netback driver will no
  longer process any Tx packets from the frontend. xenvif_up() does not
  schedule the processing of any pending Tx requests from the front end
  because the carrier is off. Without this initial kick the frontend
  just adds Tx requests to the ring without raising an event (until the
  ring is full).

  This was caused by 47103041e91794acdbc6165da0ae288d844c820b (net:
  xen-netback: convert to hw_features) which reordered the calls to
  xenvif_up() and netif_carrier_on() in xenvif_connect().

• f942dc255   xen network backend driver ... Browse Code »

  netback is the host side counterpart to the frontend driver in
  drivers/net/xen-netfront.c. The PV protocol is also implemented by
  frontend drivers in other OSes too, such as the BSDs and even Windows.

  The patch is based on the driver from the xen.git pvops kernel tree but
  has been put through the checkpatch.pl wringer plus several manual
  cleanup passes and review iterations. The driver has been moved from
  drivers/xen/netback to drivers/net/xen-netback.

  One major change from xen.git is that the guest transmit path (i.e. what
  looks like receive to netback) has been significantly reworked to remove
  the dependency on the out of tree PageForeign page flag (a core kernel
  patch which enables a per page destructor callback on the final
  put_page). This page flag was used in order to implement a grant map
  based transmit path (where guest pages are mapped directly into SKB
  frags). Instead this version of netback uses grant copy operations into
  regular memory belonging to the backend domain. Reinstating the grant
  map functionality is something which I would like to revisit in the
  future.

  Note that this driver depends on 2e820f58f7ad "xen/irq: implement
  bind_interdomain_evtchn_to_irqhandler for backend drivers" which is in
  linux next via the "xen-two" tree and is intended for the 2.6.39 merge
  window:
  git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen.git stable/backends
  this branch has only that single commit since 2.6.38-rc2 and is safe for
  cross merging into the net branch.
