David Ahern 0f457a3662 ipv4: Move cached routes to fib_nh_common
While the cached routes, nh_pcpu_rth_output and nh_rth_input, are IPv4
specific, a later patch wants to make them accessible for IPv6 nexthops
with IPv4 routes using a fib6_nh. Move the cached routes from fib_nh to
fib_nh_common and update references.

Initialization of the cached entries is moved to fib_nh_common_init,
and free is moved to fib_nh_common_release.

Change in location only, from fib_nh up to fib_nh_common; no functional
change intended.

Gustavo A. R. Silva 825f0a4eb7 i40e: Use struct_size() in kzalloc()
One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
    int stuff;
    struct boo entry[];
};

size = sizeof(struct foo) + count * sizeof(struct boo);
instance = kzalloc(size, GFP_KERNEL)

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL)

Notice that, in this case, variable size is not necessary, hence it
is removed.

This code was detected with the help of Coccinelle.

Jesse Brandeburg 0437f1a98a ice: Use bitfields where possible
The driver was converted to not use bool, but it was
neglected that the bools should have been converted to bit fields
as bit fields in software structures are ok, as long as they
use the correct kinds of unsigned types. This avoids
wasting lots of storage space to store single bit values.

One of the change hunks moves a variable lport out of
a group of "combinable" bit fields because all bits of
the u8 lport are valid and the variable can be packed in the
struct in struct holes.

Brett Creeley e40c899a64 ice: Refactor getting/setting coalesce
Currently if the driver has an uneven amount of Rx/Tx queues
setting the coalesce settings through ethtool will result in
an error. This is happening because in the setting coalesce
flow we are reporting an error if either Rx or Tx fails.

Also, the flow for setting/getting per_q_coalesce and
setting/getting coalesce settings for the entire device
is different.

Fix these issues by adding one function, ice_set_q_coalesce(),
and another, ice_get_q_coalesce(), that both getting/setting
per_q and entire device coalesce can use. This makes handling
the error cases generic between the two flows and simplifies
__ice_set_coalesce() and __ice_get_coalesce().

Also, add a header comment to __ice_set_coalesce().

netlink: strict attribute checking follow-up

Three follow-up patches for recent strict netlink validation series.

Patch 1 fixes dump handling for genetlink families which validate and parse
messages themselves (e.g. because they need different policies for diferent
commands).

Patch 2 sets bad_attr in extack in one place where this was omitted.

Patch 3 adds new NL_VALIDATE_NESTED flags for strict validation to enable
checking that NLA_F_NESTED value in received messages matches expectations
and includes this flag in NL_VALIDATE_STRICT. This would change userspace
visible behavior but the previous switching to NL_VALIDATE_STRICT for new
code is still only in net-next at the moment.

Michal Kubecek 05d7f547be genetlink: do not validate dump requests if there is no policy
Unlike do requests, dump genetlink requests now perform strict validation
by default even if the genetlink family does not set policy and maxtype
because it does validation and parsing on its own (e.g. because it wants to
allow different message format for different commands). While the null
policy will be ignored, maxtype (which would be zero) is still checked so
that any attribute will fail validation.

The solution is to only call __nla_validate() from genl_family_rcv_msg()
if family->maxtype is set.

mlxsw: Firmware version update

This patchset updates mlxsw to use a new firmware version and adds
support for split into two ports on Spectrum-2 based systems.

Patch #1 updates the firmware version to 13.2000.1122

Patch #2 queries new resources from the firmware.

Patch #3 makes use of these resources in order to support split into two
ports on Spectrum-2 based systems. The need for these resources is
explained by Shalom:

When splitting a port, different local ports need to be mapped on different
systems. For example:

SN3700 (local_ports_in_2x=2):
  * Without split:
      front panel 1   --> local port 1
      front panel 2   --> local port 5
  * Split to 2:
      front panel 1s0 --> local port 1
      front panel 1s1 --> local port 3
      front panel 2   --> local port 5

SN3800 (local_ports_in_2x=1):
  * Without split:
      front panel 1 --> local port 1
      front panel 2 --> local port 3
  * Split to 2:
      front panel 1s0 --> local port 1
      front panel 1s1 --> local port 2
      front panel 2   --> local port 3

local ports according to which the new local ports can be calculated.

Tuong Lien c0b14a0854 tipc: fix missing Name entries due to half-failover
TIPC link can temporarily fall into "half-establish" that only one of
the link endpoints is ESTABLISHED and starts to send traffic, PROTOCOL
messages, whereas the other link endpoint is not up (e.g. immediately
when the endpoint receives ACTIVATE_MSG, the network interface goes
down...).

This is a normal situation and will be settled because the link
endpoint will be eventually brought down after the link tolerance time.

However, the situation will become worse when the second link is
established before the first link endpoint goes down,
For example:

   1. Both links <1A-2A>, <1B-2B> down
   2. Link endpoint 2A up, but 1A still down (e.g. due to network
      disturbance, wrong session, etc.)
   3. Link <1B-2B> up
   4. Link endpoint 2A down (e.g. due to link tolerance timeout)
   5. Node B starts failover onto link <1B-2B>

   ==> Node A does never start link failover.

When the "half-failover" situation happens, two consequences have been
observed:

a) Peer link/node gets stuck in FAILINGOVER state;
b) Traffic or user messages that peer node is trying to failover onto
the second link can be partially or completely dropped by this node.

The consequence a) was actually solved by commit c140eb166d ("tipc:
fix failover problem"), but that commit didn't cover the b). It's due
to the fact that the tunnel link endpoint has never been prepared for a
failover, so the 'l->drop_point' (and the other data...) is not set
correctly. When a TUNNEL_MSG from peer node arrives on the link,
depending on the inner message's seqno and the current 'l->drop_point'
value, the message can be dropped (- treated as a duplicate message) or
processed.
At this early stage, the traffic messages from peer are likely to be
NAME_DISTRIBUTORs, this means some name table entries will be missed on
the node forever!

The commit resolves the issue by starting the FAILOVER process on this
node as well. Another benefit from this solution is that we ensure the
link will not be re-established until the failover ends.

Heiner Kallweit f24098f807 net: phy: improve resuming from hibernation
I got an interesting report [0] that after resuming from hibernation
the link has 100Mbps instead of 1Gbps. Reason is that another OS has
been used whilst Linux was hibernated. And this OS speeds down the link
due to WoL. Therefore, when resuming, we shouldn't expect that what
the PHY advertises is what it did when hibernating.
Easiest way to do this is removing state PHY_RESUMING. Instead always
go via PHY_UP that configures PHY advertisement.

Heiner Kallweit 22c0ef6b14 net: phy: improve pause handling
When probing the phy device we set sym and asym pause in the "supported"
bitmap (unless the PHY tells us otherwise). However we don't know yet
whether the MAC supports pause. Simply copying phy->supported to
phy->advertising will trigger advertising pause, and that's not
what we want. Therefore add phy_advertise_supported() that copies all
modes but doesn't touch the pause bits.

In phy_support_(a)sym_pause we shouldn't set any bits in the supported
bitmap because we may set a bit the PHY intentionally disabled.
Effective pause support should be the AND-combined PHY and MAC pause
capabilities. If the MAC supports everything, then it's only relevant
what the PHY supports. If MAC supports sym pause only, then we have to
clear the asym bit in phydev->supported.
Copy the pause flags only and don't touch the modes, because a driver
may have intentionally removed a mode from phydev->advertising.

Cong Wang 141b6b2ad7 net: add a generic tracepoint for TX queue timeout
Although devlink health report does a nice job on reporting TX
timeout and other NIC errors, unfortunately it requires drivers
to support it but currently only mlx5 has implemented it.
Before other drivers could catch up, it is useful to have a
generic tracepoint to monitor this kind of TX timeout. We have
been suffering TX timeout with different drivers, we plan to
start to monitor it with rasdaemon which just needs a new tracepoint.

Sample output:

  ksoftirqd/1-16    [001] ..s2   144.043173: net_dev_xmit_timeout: dev=ens3 driver=e1000 queue=0

====================
100GbE Intel Wired LAN Driver Updates 2019-05-02

This series contains updates to the ice driver only.

Anirudh introduces the framework to store queue specific information in
the VSI queue contexts.  This will allow future changes to update the
structure to hold queue specific information.

Akeem adds additional check so that if there is no queue to disable when
attempting to disable a queue, return a configuration error without
acquiring the lock.  Fixed an issue with non-trusted VFs being able to
add more than the permitted number of VLANs.

Bruce removes unreachable code and updated the function to return void
since it would never return anything but success.

Brett provides most of the changes in the series, starting with reducing
the scope of the error variable used and improved the debug message if
we fail to configure the receive queue.  Updates the driver to use a
macro instead of using the same 'for' loop throughout the driver which
helps with readability.  Fixed an issue where users were led to believe
they could set rx-usecs-high value, yet the changes to this value would
not stick because it was not yet implemented to allow changes to this
value, so implement the missing code to change the value.  Found we had
unnecessary wait when disabling queues, so remove it.  I,proved a
wasteful addition operation in our hot path by adding a member to the
ice_q_vector structure and the necessary changes to use the member which
stores the calculated vector hardware index.  Refactored the link event
flow to make it cleaner and more clear.

Maciej updates the array index when stopping transmit rings, so that
process every ring the VSI, not just the rings in a given transmit
class.

Paul adds support for setting 52 byte RSS hash keys.

Md Fahad cleaned up a runtime change to the PFINT_OICR_ENA register,
since the interrupt handlers will handle resetting the bit, if
necessary.

Tony adds a missing PHY type, which was causing warning message about an
unrecognized PHY.

Previously, we can only identify copper and fiber type, the
supported link modes of port information are always showing
SR type. This patch adds support for multiple media types,
include SR, LR CR, KR. Driver needs to query the media type
from firmware periodicly, and updates the port information.

The new port information looks like this:
Settings for eth0:
        Supported ports: [ FIBRE ]
        Supported link modes:   25000baseCR/Full
                                25000baseSR/Full

                               probe link ifdown ifup
        Link detected: yes

In order to be compatible with old firmware which only support
sfp speed, we remained using the same query command, and kept
the former logic.
