[PATCH net] xen-netback: fix fragment detection in checksum setup
The code to detect fragments in checksum_setup() was missing for IPv4 and
too eager for IPv6. (It transpires that Windows seems to send IPv6 packets
with a fragment header even if they are not a fragment - i.e. offset is zero,
and M bit is not set).

[PATCH net-next v3 5/5] xen-netback: enable IPv6 TCP GSO to the guest
This patch adds code to handle SKB_GSO_TCPV6 skbs and construct appropriate
extra or prefix segments to pass the large packet to the frontend. New
xenstore flags, feature-gso-tcpv6 and feature-gso-tcpv6-prefix, are sampled
to determine if the frontend is capable of handling such packets.

Resetting the devices during driver initialization can be a costly
operation in terms of time (especially scsi devices). This option can be

[PATCH v2] xen-netback: add a pseudo pps rate limit
VM traffic is already limited by a throughput limit, but there is no
control over the maximum packet per second (PPS).
In DDOS attack the major issue is rather PPS than throughput.
With provider offering more bandwidth to VMs, it becames easy to
coordinate a massive attack using VMs. Example: 100Mbits ~ 200kpps using
64B packets.
This patch provides a new option to limit VMs maximum packets per

[PATCH net V2] xen-netback: use jiffies_64 value to calculate credit timeout
time_after_eq() only works if the delta is < MAX_ULONG/2.
For a 32bit Dom0, if netfront sends packets at a very low rate, the time
between subsequent calls to tx_credit_exceeded() may exceed MAX_ULONG/2
and the test for timer_after_eq() will be incorrect. Credit will not be
replenished and the guest may become unable to send packets (e.g., if
prior to the long gap, all credit was exhausted).

[PATCH RFC] stubdom: Change vTPM shared page ABI
Since the vTPM implementations are being incorproated into Xen and
possibly upstream Linux, I would like to see if this protocol change
could be added before we have significant legacy implementations. If
not, I still think it would be useful as either a v2 or negotiated
protocol change.
The current vTPM protocol is a copy of the network protocol. This was
likely done for ease of implementation,

[PATCH v3 REPOST] xen-netfront: delay gARP until backend switches to Connected
After a guest is live migrated, the xen-netfront driver emits a gratuitous
ARP message, so that networking hardware on the target host's subnet can
take notice, and public routing to the guest is re-established. However,
if the packet appears on the backend interface before the backend is added
to the target host's bridge, the packet is lost, and the migrated guest's

[PATCH 7/8] netback: split event channels support
Netback and netfront only use one event channel to do tx / rx notification.
This may cause unnecessary wake-up of process routines. This patch adds a new
feature called feautre-split-event-channel to netback, enabling it to handle
Tx and Rx event separately.
Netback will use tx_irq to notify guest for tx completion, rx_irq for rx
notification.
If frontend doesn''t support this feature,
