When VXLAN offloading is enabled, be_features_check() tries to check if
an encapsulated packet is indeed a VXLAN packet. The check is not strict
enough, and considers any UDP-encapsulated ethernet frame with a 8-byte
tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE
have a 8-byte header, so they get through this check.

Force the UDP destination port to be the one that has been offloaded to
hardware.

Without this, GENEVE-encapsulated packets can end up having an incorrect
checksum when both a GENEVE and a VXLAN (offloaded) tunnel are
configured.

5.2. Action on Reception of a Query

 When a system receives a Query, it does not respond immediately.
 Instead, it delays its response by a random amount of time, bounded
 by the Max Resp Time value derived from the Max Resp Code in the
 received Query message.  A system may receive a variety of Queries on
 different interfaces and of different kinds (e.g., General Queries,
 Group-Specific Queries, and Group-and-Source-Specific Queries), each
 of which may require its own delayed response.

 Before scheduling a response to a Query, the system must first
 consider previously scheduled pending responses and in many cases
 schedule a combined response.  Therefore, the system must be able to
 maintain the following state:

 o A timer per interface for scheduling responses to General Queries.

 o A per-group and interface timer for scheduling responses to Group-
   Specific and Group-and-Source-Specific Queries.

 o A per-group and interface list of sources to be reported in the
   response to a Group-and-Source-Specific Query.

 When a new Query with the Router-Alert option arrives on an
 interface, provided the system has state to report, a delay for a
 response is randomly selected in the range (0, [Max Resp Time]) where
 Max Resp Time is derived from Max Resp Code in the received Query
 message.  The following rules are then used to determine if a Report
 needs to be scheduled and the type of Report to schedule.  The rules
 are considered in order and only the first matching rule is applied.

 1. If there is a pending response to a previous General Query
    scheduled sooner than the selected delay, no additional response
    needs to be scheduled.

 2. If the received Query is a General Query, the interface timer is
    used to schedule a response to the General Query after the
    selected delay.  Any previously pending response to a General
    Query is canceled.
--8<--

Currently the timer is rearmed with new random expiration time for
every incoming query regardless of possibly already pending report.
Which is not aligned with the above RFE.
It also might happen that higher rate of incoming queries can
postpone the report after the expiration time of the first query
causing group membership loss.

Now the per interface general query timer is rearmed only
when there is no pending report already scheduled on that interface or
the newly selected expiration time is before the already pending
scheduled report.

A single fix to avoid loading an skb->cb pointer too early.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

In ieee80211_xmit_fast(), 'info' is initialized to point to the skb
that's passed in, but that skb may later be replaced by a clone (if
it was shared), leading to an invalid pointer.

This can lead to use-after-free and also later crashes since the
real SKB's info->hw_queue doesn't get initialized properly.

Fix this by assigning info only later, when it's needed, after the
skb replacement (may have) happened.

l2tp: socket lookup fixes for l2tp_ip and l2tp_ip6

There are still some cases that aren't correctly handled in the socket

connected sockets and for sockets bound to the IPv6 unspecified
address.

bind() and connect() should now work as expected on IPPROTO_L2TP
sockets. Extra features, like SO_REUSEADDR, remain unsupported.

The matching conditions in __l2tp_ip6_bind_lookup() and
__l2tp_ip_bind_lookup() are getting hard to read. I've kept the single

updating their prototype, as these functions aren't used.

->setattr() was recently implemented for socket files to sync the socket
inode's uid to the new 'sk_uid' member of struct sock.  It does this by
copying over the ia_uid member of struct iattr.  However, ia_uid is
actually only valid when ATTR_UID is set in ia_valid, indicating that
the uid is being changed, e.g. by chown.  Other metadata operations such
as chmod or utimes leave ia_uid uninitialized.  Therefore, sk_uid could
be set to a "garbage" value from the stack.

Fix this by only copying the uid over when ATTR_UID is set.

Demoting simple flow steering rule priority (for DPDK) was achieved by
wrapping FW commands MLX4_QP_FLOW_STEERING_ATTACH/DETACH for the PF
as well, and forcing the priority to MLX4_DOMAIN_NIC in the wrapper
function for the PF and all VFs.

In function mlx4_ib_create_flow(), this change caused the main rule
creation for the PF to be wrapped, while it left the associated
tunnel steering rule creation unwrapped for the PF.

This mismatch caused rule deletion failures in mlx4_ib_destroy_flow()
for the PF when the detach wrapper function did not find the associated
tunnel-steering rule (since creation of that rule for the PF did not
go through the wrapper function).

Fix this by setting MLX4_QP_FLOW_STEERING_ATTACH/DETACH to be "native"
(so that the PF invocation does not go through the wrapper), and perform
the required priority demotion for the PF in the mlx4_ib_create_flow()
code path.

mlx4_QP_FLOW_STEERING_DETACH_wrapper first removes the steering
rule (which results in freeing the rule structure), and then
references a field in this struct (the qp number) when releasing the
busy-status on the rule's qp.

Since this memory was freed, it could reallocated and changed.
Therefore, the qp number in the struct may be incorrect,
so that we are releasing the incorrect qp. This leaves the rule's qp
in the busy state (and could possibly release an incorrect qp as well).

Fix this by saving the qp number in a local variable, for use after

ipv6: Should use consistent conditional judgement for ip6 fragment between __ip6_append_data and ip6_finish_output

There is an inconsistent conditional judgement between __ip6_append_data

just include the length of application's payload and udp6 header, don't
include the length of ipv6 header, but in ip6_finish_output use
(skb->len > ip6_skb_dst_mtu(skb)) as judgement, and skb->len include the
length of ipv6 header.

That causes some particular application's udp6 payloads whose length are
between (MTU - IPv6 Header) and MTU were fragmented by ip6_fragment even
though the rst->dev support UFO feature.

Disable netdev should come after it was closed, although no harm of doing it
before -hence the MLX5E_STATE_DESTROYING bit- but it is more natural this way.

Skip setting netdev vxlan ports and netdev rx_mode on driver load
when netdev is not yet registered.

Synchronizing with netdev state is needed only on reset flow where the
netdev remains registered for the whole reset period.

This also fixes an access before initialization of net_device.addr_list_lock
- which for some reason initialized on register_netdev - where we queued
set_rx_mode work on driver load before netdev registration.

During the initial setup, the ets command is sent to firmware
without checking if the HCA supports ets. This causes the invalid
command error. Add the ets capiblity check before sending firmware
command to initialize ets settings.
