54264e7ea0 brcmfmac: use const char * for interface name in brcmf_add_if
This function can work just fine with const pointer, it only calls
alloc_netdev which take const as well. Moreover it makes this function
more flexible as some cfg80211 callback may provide const char * as
well, e.g. add_virtual_intf. This will be needed for more advanced
interface management.

b50ddfa853 brcmfmac: fix lockup when removing P2P interface after event timeout
Removing P2P interface is handled by sending a proper request to the
firmware. On success firmware triggers an event and driver's handler
removes a matching interface.

However on event timeout we remove interface directly from the cfg80211
callback. Current code doesn't handle this case correctly as it always
assumes rtnl to be unlocked.

Fix it by adding an extra rtnl_locked parameter to functions and calling
unregister_netdevice when needed.

452fa86e98 libertas_tf: Remove create_workqueue
alloc_workqueue replaces deprecated create_workqueue().

A dedicated workqueue has been used since the workitem (viz
&priv->cmd_work per priv, which maps to lbtf_cmd_work) is involved in
actual command processing and may be used on a memory reclaim path.
The workitems require forward progress under memory pressure and hence,
WQ_MEM_RECLAIM has been set. Since there are only a fixed number of work
items, explicit concurrency limit is unnecessary here.

f568adac7d brcmfmac: slightly simplify building interface combinations
This change reorders some operations in brcmf_setup_ifmodes in hope to
make it simpler:
1) It allocates arrays right before filling them. This way it's easier
   to follow requested array length as it's immediately followed by
   code filling it. It's easier to check e.g. why we need 4 entries for
   P2P. Other than that it deduplicates some checks (e.g. for P2P).
2) It reorders code to first prepare limits and then define a new combo.
   Previously this was mixed (e.g. we were setting num of channels
   before preparing limits).
3) It modifies mbss code to use i variable just like other combos do.

40GbE Intel Wired LAN Driver Updates 2016-06-27

This series contains updates to i40e and i40evf only.

Mitch provides several changes, first adds functions to enable and disable
VSI on a VEB, which allows for configuration of limited promiscuous mode
specifically for bridging purposes.  Sets the RSS Hash Enable registers by
default now that VF RSS is configured by the PF driver.  Fixed a issue
where we could overflow the buffer, by checking the address count and bail
out of the loop at the appropriate time.  Removed the need for a reset
when the device enters limited promiscuous mode, since this was causing
heartburn for people who were using VFs and bridging.

Catherine adds a call to set the client interface down when we put the VSI
down.  Fixed an issue where RSS queues was being limited to the number
of CPUs, so if a user wants to use more queues than CPUs, we want to
trust they know what they are doing and let them.

Greg cleans up the driver suspend routine to ensure we are calling
synchronize_irq() before freeing IRQ vectors and explicitly free the other
causes interrupt resources and shut down the MSIX interrupt.

Serey fixes i40e_set_settings() to not fail when a Direct Attach (DA)
cable is used.

Avinash fixes a supported link bug by removing code which was not allowing
100BaseT to show up in the supported link modes for 10GBaseT PHYs.

Shannon adds a bit of information to the error messages to help determine
the source of error by adding VSI info to macaddr messages.

Tushar Dave fixes error received when turning off TSO on some systems,
which was caused by enabling FD_SB without checking availability of
MSIx vectors, so add the check.

Neerav fixes a possible panic when LLDP/DCBX change happens and the
driver tried to notify the client(s) for each of the PF VSIs, which would
panic when it reached a VSI that did not have any netdev associated with
it.

d913d3a763 openvswitch: fix conntrack netlink event delivery
Only the first and last netlink message for a particular conntrack are
actually sent. The first message is sent through nf_conntrack_confirm when
the conntrack is committed. The last one is sent when the conntrack is
destroyed on timeout. The other conntrack state change messages are not
advertised.

When the conntrack subsystem is used from netfilter, nf_conntrack_confirm
is called for each packet, from the postrouting hook, which in turn calls
nf_ct_deliver_cached_events to send the state change netlink messages.

This commit fixes the problem by calling nf_ct_deliver_cached_events in the
non-commit case as well.

b560f03ddf neigh: Explicitly declare RCU-bh read side critical section in neigh_xmit()
neigh_xmit() expects to be called inside an RCU-bh read side critical
section, and while one of its two current callers gets this right, the
other one doesn't.

More specifically, neigh_xmit() has two callers, mpls_forward() and
mpls_output(), and while both callers call neigh_xmit() under
rcu_read_lock(), this provides sufficient protection for neigh_xmit()
only in the case of mpls_forward(), as that is always called from
softirq context and therefore doesn't need explicit BH protection,
while mpls_output() can be called from process context with softirqs
enabled.

When mpls_output() is called from process context, with softirqs
enabled, we can be preempted by a softirq at any time, and RCU-bh
considers the completion of a softirq as signaling the end of any
pending read-side critical sections, so if we do get a softirq
while we are in the part of neigh_xmit() that expects to be run inside
an RCU-bh read side critical section, we can end up with an unexpected
RCU grace period running right in the middle of that critical section,
making things go boom.

This patch fixes this impedance mismatch in the callee, by making
neigh_xmit() always take rcu_read_{,un}lock_bh() around the code that
expects to be treated as an RCU-bh read side critical section, as this
seems a safer option than fixing it in the callers.

889ad45666 e1000e: keep VLAN interfaces functional after rxvlan off
I've got a bug report about an e1000e interface, where a VLAN interface is
set up on top of it:

$ ip link add link ens1f0 name ens1f0.99 type vlan id 99
$ ip link set ens1f0 up
$ ip link set ens1f0.99 up
$ ip addr add 192.168.99.92 dev ens1f0.99

At this point, I can ping another host on vlan 99, ip 192.168.99.91.
However, if I do the following:

$ ethtool -K ens1f0 rxvlan off

Then no traffic passes on ens1f0.99. It comes back if I toggle rxvlan on
again. I'm not sure if this is actually intended behavior, or if there's a
lack of software VLAN stripping fallback, or what, but things continue to
work if I simply don't call e1000e_vlan_strip_disable() if there are
active VLANs (plagiarizing a function from the e1000 driver here) on the
interface.

Also slipped a related-ish fix to the kerneldoc text for
e1000e_vlan_strip_disable here...

c041778c96 cfg80211: fix proto in ieee80211_data_to_8023 for frames without LLC header
The PDU length of incoming LLC frames is set to the total skb payload size
in __ieee80211_data_to_8023() of net/wireless/util.c which incorrectly
includes the length of the IEEE 802.11 header.

The resulting LLC frame header has a too large PDU length, causing the
llc_fixup_skb() function of net/llc/llc_input.c to reject the incoming
skb, effectively breaking STP.

Solve the problem by properly substracting the IEEE 802.11 frame header size
from the PDU length, allowing the LLC processor to pick up the incoming
control messages.

Special thanks to Gerry Rozema for tracking down the regression and proposing
a suitable patch.

ceb5607035 bpf, perf: delay release of BPF prog after grace period
Commit dead9f29dd ("perf: Fix race in BPF program unregister") moved
destruction of BPF program from free_event_rcu() callback to __free_event(),
which is problematic if used with tail calls: if prog A is attached as
trace event directly, but at the same time present in a tail call map used
by another trace event program elsewhere, then we need to delay destruction
via RCU grace period since it can still be in use by the program doing the
tail call (the prog first needs to be dropped from the tail call map, then
trace event with prog A attached destroyed, so we get immediate destruction).

a3d2e9f8eb tcp: do not send too big packets at retransmit time
Arjun reported a bug in TCP stack and bisected it to a recent commit.

In case where we process SACK, we can coalesce multiple skbs
into fat ones (tcp_shift_skb_data()), to lower write queue
overhead, because we do not expect to retransmit these packets.

However, SACK reneging can happen, forcing the sender to retransmit
all these packets. If skb->len is above 64KB, we then send buggy
IP packets that could hang TSO engine on cxgb4.

Neal suggested to use tcp_tso_autosize() instead of tp->gso_segs
so that we cook packets of optimal size vs TCP/pacing.

Thanks to Arjun for reporting the bug and running the tests !

6b9dc6a474 drm/i915: Removing PCI IDs that are no longer listed as Kabylake.
This is unusual. Usually IDs listed on early stages of platform
definition are kept there as reserved for later use.

However these IDs here are not listed anymore in any of steppings
and devices IDs tables for Kabylake on configurations overview
section of BSpec.

So it is better removing them before they become used in any
other future platform.
