'recoff' is read from disk and used for an argument to memcpy, so if
the value read from disk is larger than the page size, it result to
"general protection fault". This patch add additional range check for

Private rx_csum flags are now duplicate of netdev->features &
NETIF_F_RXCSUM. We remove those duplicates and now use the net_device_ops
ndo_set_features. This was based on the original patch submitted by
Michal Miroslaw . I also removed the special
case not requiring a reset for X540 hardware. It is needed just as it is
in 82599 hardware.Signed-off-by: Don Skidmore

Martin Wilck reported that systems using
the ixgbe-driver that were capable of WoL were rebooting almost as soon
as they were shut down. This is because the default WoL settings
enabled magic packet, broadcast, unicast, and multicast.Other Intel devices seem to use the stored eeprom value for initial WoL
capabilities. The 82578DM (e1000e) and 82576 (igb) the devices I looked
at had only the magic packet enabled in the eeprom, so that seems
appropriate on ixgbe-based devices as well. I set the WoL options on my
82578DM to be the same default as the ixgbe devices (umbg) and saw the
same as Martin -- almost as soon as my box shutdown, it booted again.This patch changes the default to only be the magic packet. This is the
same as the default for most Intel and non-Intel hardware currently
upstream.Signed-off-by: Andy Gospodarek

This change is meant to address possible race conditions from the status
and error bits on the RX descriptors being re-read by multiple functions in
the RX cleanup path. To resolve this I have added code that will pass the
staterr value to those functions.Signed-off-by: Alexander Duyck

This change moves work_limit, total_packets, and total_bytes into the ring
container struct of the q_vector. The advantage of this is that it should
reduce the size of memory used in the event of multiple rings being
assigned to a single q_vector. In addition it should help to reduce the
total workload for calculating itr since now total_packets and total_bytes
will be the total work done of the interrupt instead of for the ring.Signed-off-by: Alexander Duyck

Signed-off-by: Jeff Kirsher -
This patch adds support for a ring container structure to be used within
the q_vector. The basic idea is to provide a means of separating the RX
and TX rings while maintaining a common structure for their containment.
The advantage to this is that later we should be able to pass this
structure to the update_itr functions without needing to pass individual
rings.Signed-off-by: Alexander Duyck

This change is meant to update ATR so that it will use the recorded RX

We used to notify the Host every time we updated a device's status. However,
it only really needs to know when we're resetting the device, or failed to
initialize it, or when we've finished our feature negotiation.In particular, we used to wait for VIRTIO_CONFIG_S_DRIVER_OK in the
status byte before starting the device service threads. But this
corresponds to the successful finish of device initialization, which
might (like virtio_blk's partition scanning) use the device. So we
had a hack, if they used the device before we expected we started the
threads anyway.Now we hook into the finalize_features hook in the Guest: at that
point we tell the Launcher that it can rely on the features we have
acked. On the Launcher side, we look at the status at that point, and
start servicing the device.Signed-off-by: Rusty Russell

We switch back from using vmcall in 091ebf07a2408f9a56634caa0f86d9360e9af23b
because it was unreliable under kvm, but I missed one (rarely-used) place.Signed-off-by: Rusty Russell

The Host used to create some page tables for the Guest to use at the
top of Guest memory; it would then tell the Guest where this was. In
particular, it created linear mappings for 0 and 0xC0000000 addresses
because lguest used to switch to its real page tables quite late in
boot.However, since d50d8fe19 Linux initialized boot page tables in
head_32.S even before the "are we lguest?" boot jump. So, now we can
simplify things: the Host pagetable code assumes 1:1 linear mapping
until it first calls the LHCALL_NEW_PGTABLE hypercall, which we now do
before we reach C code.This also means that the Host doesn't need to know anything about the
Guest's PAGE_OFFSET. (Non-Linux guests might not even have such a
thing).Signed-off-by: Rusty Russell
