Intel Wired LAN Driver Updates 2018-05-11

This series contains fixes to the ice, ixgbe and ixgbevf drivers.

Jeff Shaw provides a fix to ensure rq_last_status gets set, whether or
not the hardware responds with an error in the ice driver.

Emil adds a check for unsupported module during the reset routine for
ixgbe.

Luc Van Oostenryck fixes ixgbevf_xmit_frame() where it was not using the
correct return value (int).

Colin Ian King fixes a potential resource leak in ixgbe, where we were
not freeing ipsec in our cleanup path.

rxrpc: Fixes

Here are three fixes for AF_RXRPC and two tracepoints that were useful for
finding them:

 (1) Fix missing start of expect-Rx-by timeout on initial packet
     transmission so that calls will time out if the peer doesn't respond.

 (2) Fix error reception on AF_INET6 sockets by using the correct family of
     sockopts on the UDP transport socket.

 (3) Fix setting the minimum security level on kernel calls so that they
     can be encrypted.

 (4) Add a tracepoint to log ICMP/ICMP6 and other error reports from the
     transport socket.

 (5) Add a tracepoint to log UDP sendmsg failure so that we can find out if
     transmission failure occurred on the UDP socket.

The caller calls action's ->init() and passes pointer to "struct tc_action *a",
which later may be initialized to point at the existing action, otherwise
"struct tc_action *a" is still invalid, and therefore dereferencing it is an
error as happens in tcf_idr_release, where refcnt is decremented.

So in case of missing flags tcf_idr_release must be called only for
existing actions.

  first added to git;
* ping_v4_sendmsg one was copy/pasted in c319b4d7.

Whenever return happens in udp_sendmsg() or ping_v4_sendmsg() IP options
have to be freed if they were allocated previously.

bonding: bug fixes and regressions

Fixes to bonding driver for balance-alb mode, suitable for stable.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

There was a regression at some point from the intended functionality of
commit f60c3704 ("bonding: Fix alb mode to only use first level
vlans.")

Given the return value vlan_get_encap_level() we need to store the nest
level of the bond device, and then compare the vlan's encap level to
this. Without this, this check always fails and learning packets are
never sent.

In addition, this same commit caused a regression in the behavior of
balance_alb, which requires learning packets be sent for all interfaces
using the slave's mac in order to load balance properly. For vlan's
that have not set a user mac, we can send after checking one bit.
Otherwise we need send the set mac, albeit defeating rx load balancing
for that vlan.

AF_RXRPC tries to turn on IP_RECVERR and IP_MTU_DISCOVER on the UDP socket

socket is of the AF_INET6 family.

The expect_rx_by call timeout is supposed to be set when a call is started
to indicate that we need to receive a packet by that point.  This is
currently put back every time we receive a packet, but it isn't started
when we first send a packet.  Without this, the call may wait forever if
the server doesn't deign to reply.

Fix this by setting the timeout upon a successful UDP sendmsg call for the
first DATA packet.  The timeout is initiated only for initial transmission
and not for subsequent retries as we don't want the retry mechanism to
extend the timeout indefinitely.

Change type of sample-interval and adaptive_rx_coal parameters in mlx4
driver to u32 as the ethtool holds them as u32 and these parameters are
not limited due to mlx4 HW.

Damir reported a breakage of SO_BINDTODEVICE for UDP sockets.
In absence of VRF devices, after commit fb74c277 ("net:
ipv4: add second dif to udp socket lookups") the dif mismatch
isn't fatal anymore for UDP socket lookup with non null
sk_bound_dev_if, breaking SO_BINDTODEVICE semantics.

This changeset addresses the issue making the dif match mandatory
again in the above scenario.

After route cache is flushed via ipv4_sysctl_rtcache_flush(), we forget
to reset fnhe_mtu_locked in rt_bind_exception(). When pmtu is updated
in __ip_rt_update_pmtu(), it will return directly since the pmtu is
still locked. e.g.

+ ip netns exec client ping 10.10.1.1 -c 1 -s 1400 -M do
PING 10.10.1.1 (10.10.1.1) 1400(1428) bytes of data.

On older windows hosts the net_device instance is returned to
the caller of rndis_filter_device_add() without having the presence
bit set first. This would cause any subsequent calls to network device
operations (e.g. MTU change, channel change) to fail after the device
is detached once, returning -ENODEV.

Instead of returning the device instabce, we take the exit path where
we call netif_device_attach()

Since commit 29a5dcae ("nfp: flower: offload phys port MTU change") we
take encapsulation headroom into account when calculating the max allowed
MTU.  This is unnecessary as the max MTU advertised by firmware should have
already accounted for encap headroom.

Subtracting headroom twice brings the max MTU below what's necessary for
some deployments.

====================
qed*: Rdma fixes

This patch series include two fixes for bugs related to rdma.
The first has to do with loading the driver over an iWARP
device.
The second fixes a previous commit that added proper link
indication for iWARP / RoCE.
