Now when bond-related code is moved from net/core/dev.c into bonding
code, multiple priv_flags are not needed anymore. So let them rot.

Register slave pointer as rx_handler data. That would eventually prevent
need to loop over slave devices to find the right slave.

9 years agoxen network backend driver
Ian Campbell [Tue, 15 Mar 2011 00:06:18 +0000]
xen network backend driver

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.

9 years agobonding: Improve syslog message at device creation time
Phil Oester [Mon, 14 Mar 2011 06:22:06 +0000]
bonding: Improve syslog message at device creation time

When the bonding module is loaded, it creates bond0 by default.
Then, when attempting to create bond0, the following messages
are printed to syslog:

    kernel: bonding: bond0 is being created...
    kernel: bonding: Bond creation failed.

Which seems to indicate a problem, when in reality there is no
problem.  Since the actual error code is passed down from bond_create,
make use of it to print a bit less ominous message:

    kernel: bonding: bond0 is being created...
    kernel: bond0 already exists.

bonding: Call netif_carrier_off after register_netdevice

Bringing up a bond interface with all network cables disconnected
does not properly set the interface as DOWN because the call to
netif_carrier_off occurs too early in bond_init.  The call needs
to occur after register_netdevice has set dev->reg_state to
NETREG_REGISTERED, so that netif_carrier_off will trigger the

9 years agobonding: Incorrect TX queue offset
Phil Oester [Mon, 14 Mar 2011 06:22:04 +0000]
bonding: Incorrect TX queue offset

When packets come in from a device with >= 16 receive queues
headed out a bonding interface, syslog gets filled with this:

    kernel: bond0 selects TX queue 16, but real number of TX queues is 16

because queue_mapping is offset by 1.  Adjust return value
to account for the offset.

This is a revision of my earlier patch (which did not use the
skb_rx_queue_* helpers - thanks to Ben for the suggestion).
Andy submitted a similar patch which emits a pr_warning on
invalid queue selection, but I believe the log spew is
not useful.  We can revisit that question in the future,
but in the interim I believe fixing the core problem is
worthwhile.

IPVS: Minimise ip_vs_leave when CONFIG_SYSCTL is undefined

Much of ip_vs_leave() is unnecessary if CONFIG_SYSCTL is undefined.

I tried an approach of breaking the now #ifdef'ed portions out
into a separate function. However this appeared to grow the
compiled code on x86_64 by about 200 bytes in the case where
CONFIG_SYSCTL is defined. So I have gone with the simpler though
less elegant #ifdef'ed solution for now.

Julian Anastasov [Sun, 13 Mar 2011 23:37:49 +0000]
ipvs: properly zero stats and rates

  Currently, the new percpu counters are not zeroed and
the zero commands do not work as expected, we still show the old
sum of percpu values. OTOH, we can not reset the percpu counters
from user context without causing the incrementing to use old
and bogus values.

  So, as Eric Dumazet suggested fix that by moving all overhead
to stats reading in user context. Do not introduce overhead in
timer context (estimator) and incrementing (packet handling in
softirqs).

  The new ustats0 field holds the zero point for all
counter values, the rates always use 0 as base value as before.
When showing the values to user space just give the difference
between counters and the base values. The only drawback is that
percpu stats are not zeroed, they are accessible only from /proc
and are new interface, so it should not be a compatibility problem
as long as the sum stats are correct after zeroing.

macvlan : fix checksums error when we are in bridge mode

When the lower device has offloading capabilities, the packets checksums
are not computed. That leads to have any macvlan port in bridge mode to
not work because the packets are dropped due to a bad checksum.

If the macvlan is in bridge mode, the packet is forwarded to another
macvlan port and reach the network stack where it looks for a checksum
but this one was not computed due to the offloading of the lower device.
In this case, we have to set the packet with CHECKSUM_UNNECESSARY
when it is forwarded to a bridged port and restore the previous value of
ip_summed when the packet goes to the lowerdev.

9 years agobridge: skip forwarding delay if not using STP
stephen hemminger [Thu, 10 Mar 2011 05:57:04 +0000]
bridge: skip forwarding delay if not using STP

If Spanning Tree Protocol is not enabled, there is no good reason for
the bridge code to wait for the forwarding delay period before enabling
the link. The purpose of the forwarding delay is to allow STP to
learn about other bridges before nominating itself.

The only possible impact is that when starting up a new port
the bridge may flood a packet now, where previously it might have
seen traffic from the other host and preseeded the forwarding table.

Includes change for local variable br already available in that func.

9 years agobridge: control carrier based on ports online
stephen hemminger [Mon, 7 Mar 2011 08:34:06 +0000]
bridge: control carrier based on ports online

This makes the bridge device behave like a physical device.
In earlier releases the bridge always asserted carrier. This
changes the behavior so that bridge device carrier is on only
if one or more ports are in the forwarding state. This
should help IPv6 autoconfiguration, DHCP, and routing daemons.

I did brief testing with Network and Virt manager and they
seem fine, but since this changes behavior of bridge, it should
wait until net-next (2.6.39).

The headers of pktgen were incorrectly added in a pktgen packet
without frags (frags=0). There was an offset in the pktgen headers.

The cause was in reusing the pgh variable as a return variable in skb_put
