sfc: don't update stats on VF when called in atomic context
The ifenslave command to set up a bond runs in an atomic
context, and it queries the stats on the devices that are
being enslaved. A VF needs to make an MCDI call to update
its stats, which is not allowed in atomic context.
The releasing of the stats_lock is moved to the beginning of
the VF stats update function so that in_interrupt() can be
used; it must be taken again before returning from this
function.

sfc: suppress vadaptor stats when EVB is not present
The raw_mask array is not initialised, so it needs to be

If the EVB capability is not present, a port cannot have multiple

the corresponding vadaptor stats, so this redundancy can be
removed from the ethtool stats output.

Now, on port probe, we install untagged VLAN (vid=0) support for each port
as the default. This is equivalent to the command:
bridge vlan add vid 0 dev DEV self
Accepting untagged VLAN pkts is a reasonable default, but the user could
override this with:
bridge vlan del vid 0 dev DEV self
With this, we no longer need 8021q module to install vid=0 when port interface
opens. In fact, we don't need support for legacy VLAN ndo ops at all since
they're superseded by bridge_setlink/dellink. So remove legacy VLAN ndo ops
support in driver. (The legacy VLAN ndo ops are supported by bonding/team
drivers, but don't fit into the transaction model offered by switchdev, so
switching all VLAN functions to bridge_setlink/dellink switchdev support gets
us stacked driver + transaction model support).

The legacy ops are needed if using 8021q driver module to setup VLANs on
the port. But an alternative exists in using bridge_setlink/delink to
setup VLANs, which doesn't depend on 8021q module. So rocker will switch
to the newer setlink/dellink ops. VLANs can added/delete from the port,
regardless if port is bridged or not, using the bridge commands:
bridge vlan [add|del] vid VID dev DEV self
(Yes, I agree it's confusing to use the "bridge" command to set a VLAN on a
non-bridged port).
Using setlink/dellink over legacy ops let's us handle the stacked driver
case automatically. It's built-in. setlink also pass additional flags
(PVID, egress untagged) that aren't available with the legacy ops.

rocker: install/remove router MAC for untagged VLAN when joining/leaving bridge
When the port joins a bridge, the port's internal VLAN ID needs to change
to the bridge's internal VLAN ID. Likewise, when leaving the bridge, the
internal VLAN ID reverts back the port's original internal VLAN ID. (The
internal VLAN ID is used by device to internally mark untagged pkts with
some VLAN, which will eventually be removed on egress...think PVID). When
the internal VLAN ID changes, we need to update the VLAN table entries and
the router MAC entries for IP/IPv6 to reflect the new internal VLAN ID.
This patch makes use of the common rocker_port_vlan_add/del functions to
make sure the tables are updated for the current internal VLAN ID.

bnx2x: Alloc 4k fragment for each rx ring buffer element

xen: netback: read hotplug script once at start of day.
When we come to tear things down in netback_remove() and generate the
uevent it is possible that the xenstore directory has already been
removed (details below).
In such cases netback_uevent() won't be able to read the hotplug
script and will write a xenstore error node.
A recent change to the hypervisor exposed this race such that we now
sometimes lose it (where apparently we didn't ever before).
Instead read the hotplug script configuration during setup and use it
for the lifetime of the backend device.
The apparently more obvious fix of moving the transition to
state=Closed in netback_remove() to after the uevent does not work
because it is possible that we are already in state=Closed (in
reaction to the guest having disconnected as it shutdown). Being
already in Closed means the toolstack is at liberty to start tearing
down the xenstore directories. In principal it might be possible to
arrange to unregister the device sooner (e.g on transition to Closing)
such that xenstore would still be there but this state machine is
fragile and prone to anger...
A modern Xen system only relies on the hotplug uevent for driver
domains, when the backend is in the same domain as the toolstack it
will run the necessary setup/teardown directly in the correct sequence
wrt xenstore changes.

This is a problem for its caler: dsa_switch_setup() which uses IS_ERR()

to proceed with dsa_switch_setup() and operate on invalid memory
addresses. This can be easily reproduced by having e.g: the bcm_sf2

tcp: fix child sockets to use system default congestion control if not set
Linux 3.17 and earlier are explicitly engineered so that if the app
doesn't specifically request a CC module on a listener before the SYN
arrives, then the child gets the system default CC when the connection
is established. See tcp_init_congestion_control() in 3.17 or earlier,
which says "if no choice made yet assign the current value set as
default". The change ("net: tcp: assign tcp cong_ops when tcp sk is
created") altered these semantics, so that children got their parent
listener's congestion control even if the system default had changed
after the listener was created.
This commit returns to those original semantics from 3.17 and earlier,
since they are the original semantics from 2007 in
4d4d3d1e8 ("[TCP]:
Congestion control initialization."), and some Linux congestion
control workflows depend on that.
In summary, if a listener socket specifically sets TCP_CONGESTION to
"x", or the route locks the CC module to "x", then the child gets
"x". Otherwise the child gets current system default from
net.ipv4.tcp_congestion_control. That's the behavior in 3.17 and
earlier, and this commit restores that.

net/rds: SOL_RDS socket option to explicitly select transport
Today the underlying transport (TCP or IB) for a PF_RDS socket is
implicitly selected based on the local address used to bind(2) the
PF_RDS socket. This results in some non-deterministic behavior when
there are un-numbered and IPoIB interfaces sharing the same IP address.
It also places the constraint that the IB interface must have an IP
address (and thus, IPoIB) configured on it.
The non-determinism may be avoided by providing the user-space application
a socket option that allows it to explicitly select the transport
prior to bind(2).

bpf: add missing rcu protection when releasing programs from prog_array
Normally the program attachment place (like sockets, qdiscs) takes
care of rcu protection and calls bpf_prog_put() after a grace period.
The programs stored inside prog_array may not be attached anywhere,
so prog_array needs to take care of preserving rcu protection.
Otherwise bpf_tail_call() will race with bpf_prog_put().
To solve that introduce bpf_prog_put_rcu() helper function and use
it in 3 places where unattached program can decrement refcnt:
closing program fd, deleting/replacing program in prog_array.

net: systemport: rewrite bcm_sysport_rx_refill
Currently, bcm_sysport_desc_rx() calls bcm_sysport_rx_refill() at the end of Rx
packet processing loop, after the current Rx packet has already been passed to
napi_gro_receive(). However, bcm_sysport_rx_refill() might fail to allocate a new
Rx skb, thus leaving a hole on the Rx queue where no valid Rx buffer exists.
To eliminate this situation:
1. Rewrite bcm_sysport_rx_refill() to retain the current Rx skb on the
Rx queue if a new replacement Rx skb can't be allocated and DMA-mapped.
In this case, the data on the current Rx skb is effectively dropped.
2. Modify bcm_sysport_desc_rx() to call bcm_sysport_rx_refill() at the
top of Rx packet processing loop, so that the new replacement Rx skb is
already in place before the current Rx skb is processed.

It seems impossible to get this driver to work on most 32-bit
hardware, so it's better to add an explicit dependency, in
order to let us keep building 'allmodconfig' kernels on
all architectures.
As the driver is meant for the internal hardware on an arm64 SoC, this
is not a problem for usability. Allowing the build on all 64-bit
architectures rather than just CONFIG_ARM64 on the other hand means that
we get the benefit of build testing on x86.
