40GbE Intel Wired LAN Driver Updates 2018-05-22

This series contains updates to i40e only.

Jake provides all the changes in this series starting with making it
consistent in how we approach the bit lock.  Fixed the reporting of the
VEB statistics and the queue statistics to always return every queue
even if it is not currently in use.  Use WARN_ONCE() so that the first
time we end up with an incorrect size we will dump a stack trace and a
message to help highlight the issue early in testing.  Folded the fixed
string prefix into the stat string definition.  Instead of using a
separate char *p pointer when copying strings, use the data pointer
directly.  Added code comments for several of the statistic functions to
better explain the number and ordering of statistics.

tcp: reduce quickack pressure for ECN

Small patch series changing TCP behavior vs quickack and ECN

First patch is a refactoring, adding parameter to tcp_incr_quickack()
and tcp_enter_quickack_mode() helpers.

Second patch implements the change, lowering number of ACK packets
sent after an ECN event.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

ECN signals currently forces TCP to enter quickack mode for
up to 16 (TCP_MAX_QUICKACKS) following incoming packets.

We believe this is not needed, and only sending one immediate ack
for the current packet should be enough.

This should reduce the extra load noticed in DCTCP environments,
after congestion events.

This is part 2 of our effort to reduce pure ACK packets.

Initial net_device implementation used ingress_lock spinlock to synchronize
ingress path of device. This lock was used in both process and bh context.
In some code paths action map lock was obtained while holding ingress_lock.
Commit e1e992e5 ("[NET_SCHED] protect action config/dump from irqs")
modified actions to always disable bh, while using action map lock, in
order to prevent deadlock on ingress_lock in softirq. This lock was removed
from net_device, so disabling bh, while accessing action map, is no longer
necessary.

Replace all action idr spinlock usage with regular calls that do not
disable bh.

net/ipv6: Fix route append and replace use cases

This patch set fixes a few append and replace uses cases for IPv6 and
adds test cases that codifies the expectations of how append and replace
are expected to work. In paricular it allows a multipath route to have
a dev-only nexthop, something Thomas tried to accomplish with commit
edd7ceb7 ("ipv6: Allow non-gateway ECMP for IPv6") which had to be
reverted because of breakage, and to replace an existing FIB entry
with a reject route.

There are a number of inconsistent and surprising aspects to the Linux
API for adding, deleting, replacing and changing FIB entries. For example,
with IPv4 NLM_F_APPEND means insert the route after any existing entries
with the same key (prefix + priority + TOS for IPv4) and NLM_F_CREATE
without the append flag inserts the new route before any existing entries.

IPv6 on the other hand attempts to guess whether a new route should be
appended to an existing one, possibly creating a multipath route, or to
add a new entry after any existing ones. This applies to both the 'append'
(NLM_F_CREATE + NLM_F_APPEND) and 'prepend' (NLM_F_CREATE only) cases
meaning for IPv6 the NLM_F_APPEND is basically ignored. This guessing
whether the route should be added to a multipath route (gateway routes)
or inserted after existing entries (non-gateway based routes) means a
multipath route can not have a dev only nexthop (potentially required in
some cases - tunnels or VRF route leaking for example) and route 'replace'
is a bit adhoc treating gateway based routes and dev-only / reject routes
differently.

This has led to frustration with developers working on routing suites
such as FRR where workarounds such as delete and add are used instead of
replace.

After this patch set there are 2 differences between IPv4 and IPv6:
1. 'ip ro prepend' = NLM_F_CREATE only
    IPv4 adds the new route before any existing ones
    IPv6 adds new route after any existing ones

2. 'ip ro append' = NLM_F_CREATE|NLM_F_APPEND
   IPv4 adds the new route after any existing ones
   IPv6 adds the nexthop to existing routes converting to multipath

For the former, there are cases where we want same prefix routes added
after existing ones (e.g., multicast, prefix routes for macvlan when used
for virtual router redundancy). Requiring the APPEND flag to add a new
route to an existing one helps here but is a slight change in behavior
since prepend with gateway routes now create a separate entry.

For the latter IPv6 behavior is preferred - appending a route for the same
prefix and metric to make a multipath route, so really IPv4 not allowing an
existing route to be updated is the limiter. This will be fixed when
nexthops become separate objects - a future patch set.

Thank you to Thomas and Ido for testing earlier versions of this set, and
to Ido for providing an update to the mlxsw driver.

Bring consistency to ipv6 route replace and append semantics.

Remove rt6_qualify_for_ecmp which is just guess work. It fails in 2 cases:
1. can not replace a route with a reject route. Existing code appends
   a new route instead of replacing the existing one.

2. can not have a multipath route where a leg uses a dev only nexthop

Existing use cases affected by this change:
1. adding a route with existing prefix and metric using NLM_F_CREATE
   without NLM_F_APPEND or NLM_F_EXCL (ie., what iproute2 calls
   'prepend'). Existing code auto-determines that the new nexthop can
   be appended to an existing route to create a multipath route. This
   change breaks that by requiring the APPEND flag for the new route
   to be added to an existing one. Instead the prepend just adds another
   route entry.

2. route replace. Existing code replaces first matching multipath route
   if new route is multipath capable and fallback to first matching
   non-ECMP route (reject or dev only route) in case one isn't available.
   New behavior replaces first matching route. (Thanks to Ido for spotting
   this one)

Note: Newer iproute2 is needed to display multipath routes with a dev-only
      nexthop. This is due to a bug in iproute2 and parsing nexthops.

A future patch is going to add a helper function i40e_add_ethtool_stats
that will help lower the amount of boiler plate code in the
i40e_get_ethtool_stats function.

This conversion will take place over many patches, and the helper
function will work by directly updating a reference to the data pointer.

Since this would not work combined with the current method of accessing
data like an array, update all the code that copies stats into the data
buffer to use direct updates to the pointer instead of array accesses.

This will prevent incorrect stat updates for patches in between the
conversion.

Similarly, when copying strings, we used a separate char *p pointer.
Instead, use the data pointer directly as it's already a (u8 *) type
which is the same size.

The ethtool API for obtaining device statistics is not intended to allow
runtime changes in the number of statistics reported. It may *appear*
this way, as there is an ability to request the number of stats using
ethtool_get_set_count(). However, it is expected that this must always
return the same value for invocations of the same device.

If we don't satisfy this contract, and allow the number of stats to
change during run time, we could cause invalid memory accesses or report
the stat strings incorrectly. This is because the API for obtaining
stats is to (1) get the size, (2) get the strings and finally (3) get
the stats. Since these are each separate ethtool op commands, it is not
possible to maintain consistency by holding the RTNL lock over the whole
operation. This results in the potential for a race condition to occur
where the size changed between any of the 3 calls.

Avoid this issue by requiring that we always return the same value for
a given device. We can check any values which remain constant for the
life of the device, but must not report different sizes depending on
runtime attributes.

This patch specifically fixes the queue statistics to always return
every queue even if it's not currently in use.

TLS data structures split the TX and RX components in 'net-next',
put the new struct members from the bug fix in 'net' into the RX
part.

The 'net-next' tree had some reworking of how the ERSPAN code works in
the GRE tunneling code, overlapping with a one-line headroom
calculation fix in 'net'.

Overlapping changes in __sock_map_ctx_update_elem(), keep the bits
that read the prog members via READ_ONCE() into local variables
before using them.

Fix below build warning:

WARNING: vmlinux.o(.text+0x422bb8): Section mismatch in reference from
the function vmcore_add_device_dump() to the function
.init.text:get_vmcore_size.constprop.5()

The function vmcore_add_device_dump() references
the function __init get_vmcore_size.constprop.5().
This is often because vmcore_add_device_dump lacks a __init
annotation or the annotation of get_vmcore_size.constprop.5 is wrong.

immdlen field of FW_ETH_TX_PKT_WR is filled in a wrong way,
we must copy the length of all the cpls encapsulated in fw
work request. In the xmit path we missed adding the length
of CPL_TX_PKT_CORE but we added the length of WR_HDR and it
worked because WR_HDR and CPL_TX_PKT_CORE are of same length.
Add the length of cpl_tx_pkt_core not WR_HDR's. This also
fixes the lso cpl errors for udp tunnels

If CONFIG_GPIOLIB is disabled, gpiod_put() becomes a stub that produces a
warning, this helped identify that we could be attempting to release a NULL
pl->link_gpio GPIO descriptor, so guard against that.
