The main item is the addition of the Power9 Machine Check handler. This was
delayed to make sure some details were correct, and is as minimal as possible.
The rest is small fixes, two for the Power9 PMU, two dealing with obscure
toolchain problems, two for the PowerNV IOMMU code (used by VFIO), and one to
fix a crash on 32-bit machines with macio devices due to missing dma_ops.

The previous idea was to check whether a net namespace is in
net_exit_list or not. It doesn't work, because net->exit_list is used in
__register_pernet_operations and __unregister_pernet_operations where
all namespaces are added to a temporary list to make cleanup in a error
case, so list_empty(&net->exit_list) always returns false.

This patch advances the qed* drivers into using the newer firmware -
This solves several firmware bugs, mostly related [but not limited to]
various init/deinit issues in various offloaded protocols.
It also introduces a major 4-Cached SGE change in firmware, which can be
seen in the storage drivers' changes.
In addition, this firmware is required for supporting the new QL41xxx
series of adapters; While this patch doesn't add the actual support,
the firmware contains the necessary initialization & firmware logic to
operate such adapters [actual support would be added later on].

Provide the ability to control on a per-route basis whether the TTL
value from an MPLS packet is propagated to an IPv4/IPv6 packet when
the last label is popped as per the theoretical model in RFC 3443
through a new route attribute, RTA_TTL_PROPAGATE which can be 0 to
mean disable propagation and 1 to mean enable propagation.
In order to provide the ability to change the behaviour for packets
arriving with IPv4/IPv6 Explicit Null labels and to provide an easy
way for a user to change the behaviour for all existing routes without
having to reprogram them, a global knob is provided. This is done
through the addition of a new per-namespace sysctl,
"net.mpls.ip_ttl_propagate", which defaults to enabled. If the
per-route attribute is set (either enabled or disabled) then it

gtp: misc improvements
This is a resent of last series that missed the merge window. There
are no changes compared to v4.
v4: Compared to v3 it contains mostly smallish naming and spelling fixes.
It also drops the documentation patch, Harald did a better job with the
documentation and the some things I described do not yet match the implementation.
I'll readd the relevant parts with a follow up series.
This series lays the groundwork for removing the socket references from
the GTP netdevice by removing duplicate code and simplifying the logic on
some code paths.
It slighly changes the GTP genl API by making the socket parameters optional
(though one of them is still required).
The removal of the socket references will break the 1:1 releation between
GTP netdevice and GTP socket that prevents us to support multiple VRFs with
overlapping IP addresse spaces attached to the same GTP-U entity (needed for
multi APN support, coming a follow up series).
Pablo found a socket hold problem in v2. In order to solve that I had to
switch the socket references from the struct socket to the internal
struct sock. This should have no functionl impact, but we can now hang
on to the reference without blocking user space from closing the GTP socket.
v4->v5:
* resent for new merge window
v3->v4:
* drop the documentation patch
* spelling fixes
* pass nlattr instead of genl_info into gtp_find_dev,
makes the code slightly more compact and readable
v2->v3:
* add documentation to explain the goal of all these changes
* incorporate review comments
* switch from struct socket to struct sock

Having both GTPv0-U and GTPv1-U is not always desirable.

from listening on the v0 port (see 3GPP TS 29.281, Sect. 1).
A future change will completely decouple the sockets from the
network device. Till then, at least one of the sockets needs to
be specified (either v0 or v1), the other is optional.

After enabling the UDP encapsulation, only the sk member is used.

Andreas reports kernel oops during rmmod of the br_netfilter module.
Hannes debugged the oops down to a NULL rt6info->rt6i_indev.
Problem is that br_netfilter has the nasty concept of adding a fake
rtable to skb->dst; this happens in a br_netfilter prerouting hook.
A second hook (in bridge LOCAL_IN) is supposed to remove these again
before the skb is handed up the stack.
However, on module unload hooks get unregistered which means an
skb could traverse the prerouting hook that attaches the fake_rtable,
while the 'fake rtable remove' hook gets removed from the hooklist
immediately after.

ip6_fragment, in case skb has a fraglist, checks if the
skb is cloned. If it is, it will move to the 'slow path' and allocates
new skbs for each fragment.
However, right before entering the slowpath loop, it updates the
nexthdr value of the last ipv6 extension header to NEXTHDR_FRAGMENT,
to account for the fragment header that will be inserted in the new
ipv6-fragment skbs.
In case original skb is cloned this munges nexthdr value of another
skb. Avoid this by doing the nexthdr update for each of the new fragment
skbs separately.
This was observed with tcpdump on a bridge device where netfilter ipv6
reassembly is active: tcpdump shows malformed fragment headers as
the l4 header (icmpv6, tcp, etc). is decoded as a fragment header.

Commit 27596472473a ("ipv6: fix ECMP route replacement") introduced a
loop that removes all siblings of an ECMP route that is being
replaced. However, this loop doesn't stop when it has replaced
siblings, and keeps removing other routes with a higher metric.
We also end up triggering the WARN_ON after the loop, because after
this nsiblings < 0.
Instead, stop the loop when we have taken care of all routes with the
same metric as the route being replaced.

Karel Rericha reported that in his test case, ICMP packets going through
boxes had normally about 5ms latency. But when running nft, actually
listing the sets with interval flags, latency would go up to 30-100ms.
This was observed when router throughput is from 600Mbps to 2Gbps.
This is because we use a single global spinlock to protect the whole
rbtree sets, so "dumping sets" will race with the "key lookup" inevitably.
But actually they are all _readers_, so it's ok to convert the spinlock
to rwlock to avoid competition between them. Also use per-set rwlock since
each set is independent.

this allows to assign connection tracking helpers to
connections via nft objref infrastructure.
The idea is to first specifiy a helper object:
table ip filter {
ct helper some-name {
type "ftp"
protocol tcp
l3proto ip
}
}
and then assign it via
nft add ... ct helper set "some-name"
helper assignment works for new conntracks only as we cannot expand the
conntrack extension area once it has been committed to the main conntrack
table.
ipv4 and ipv6 protocols are tracked stored separately so
we can also handle families that observe both ipv4 and ipv6 traffic.

net: dsa: mv88e6xxx: rework ATU support
The purpose of this patch series is to rework the code related to the
Address Translation Unit (ATU), and bring support for it to the 88E6390
family of switch chips.
All Global (1) ATU related code have been reworked and moved to its own
file. Some port related bits used for ATU configuration (such as the
Learn2All and MessagePort feature) have also been taken care of.
The ports' mode and egress flooding mode have been refactored to fix the
egress of frames with unknown unicast or multicast destination address,
and write all these bits regardless the port mode (Normal, DSA, etc.)
Finally remove the eth_addr_greater which was only used by mv88e6xxx.
Changes in v2:
- add Reviewed-by tags
- split mv88e6xxx_g1_atu_set_age_time and mv88e6xxx_atu_setup addition
- remove DSA_TAG_PROTO_TRAILER check
- split Message Port and Learn2All addition
- remove unused MV88E6XXX_FLAG_G1_ATU_FID flag
- add dsa_is_normal_port helper

eth_addr_greater() was introduced for the mv88e6xxx driver, but is not
used anymore. There is no other user, thus remove this function.

Add a new operation to disable the DA, SA and VTU priority override.
Setting such limit is not likely to be used soon, so provide a
port_disable_pri_override operation directly. This can be changed later
for port_set_pri_override when we'll need it.
Also remove the now obsolete mv88e6xxx_6320_family helper.

The Marvell switch ports can be configured to allow or prevent egress of
frames with an unknown unicast or multicast destination address.
Some switch chips such as 88E6095 and 88E6185 have two disjoint bits in
Port Control Register (0x04) bit 2 "Forward Unknown" (for unicast) and
Port Control 2 Register (0x08) bit 6 "Default Forward" (for multicast).
Other chips such as 88E6085, 88E6123, 88E6352, and 88E6390 have a 2-bit
value in Port Control Register (0x04) bits 3:2 "EgressFloods".
The current code does not fully implement the disjoint bits variant and
assigns incorrect ones to some chip models. Fix that with two
implementation references (6185 and 6352 that I currently have) of a
port_set_egress_floods operation (as named in datasheets).
Old chips such as 88E6060 don't have egress flooding mode, so don't
error out if the operation is not provided.

A switch port mode is defined by the association of its egress mode, its
frame mode and if supported or required, the ether type value.
Pack all this in a mv88e6xxx_set_port_mode function and provide helpers
for the Normal Network mode, the DSA mode, and the Ether Type DSA mode,
as well as an helper to setup a port's mode depending on its nature.
Define PORT_ETH_TYPE_DEFAULT for the 0x9100 reset value of port E Type.
