Florian Fainelli says:

====================
net: Get rid of switchdev_port_attr_get()

This patch series splits the removal of the switchdev_ops that was
proposed a few times before and first tackles the easy part which is the
removal of the single call to switchdev_port_attr_get() within the
bridge code.

As suggestd by Ido, this patch series adds a
SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS which is used in the same
context as the caller of switchdev_port_attr_set(), so not deferred, and
then the operation is carried out in deferred context with setting a
support bridge port flag.

Follow-up patches will do the switchdev_ops removal after introducing
the proper helpers for the switchdev blocking notifier to work across
stacked devices (unlike the previous submissions).

David this does depend on Russell's "[PATCH net-next v5 0/3] net: dsa:
mv88e6xxx: fix IPv6".

Changes in v3:

- rebased against net-next/master after Russell's IPv6 changes to DSA
- ignore prepare/commit phase for PRE_BRIDGE_FLAGS since we don't
  want to trigger the WARN() in net/switchdev/switchdev.c in the commit
  phase

Changes in v2:

- differentiate callers not supporting switchdev_port_attr_set() from
  the driver not being able to support specific bridge flags

- pass "mask" instead of "flags" for the PRE_BRIDGE_FLAGS check

- skip prepare phase for PRE_BRIDGE_FLAGS

- corrected documentation a bit more

- tested bridge_vlan_aware.sh with veth/VRF

010c8f01aa net: Get rid of switchdev_port_attr_get()
With the bridge no longer calling switchdev_port_attr_get() to obtain
the supported bridge port flags from a driver but instead trying to set
the bridge port flags directly and relying on driver to reject
unsupported configurations, we can effectively get rid of
switchdev_port_attr_get() entirely since this was the only place where
it was called.

cc0c207a5d net: Remove SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS_SUPPORT
Now that we have converted the bridge code and the drivers to check for
bridge port(s) flags at the time we try to set them, there is no need
for a get() -> set() sequence anymore and
SWITCHDEV_ATTR_ID_PORT_BRIDGE_FLAGS_SUPPORT therefore becomes unused.

db088ca3c1 Merge branch 'net-dsa-mv88e6xxx-fix-IPv6'
Florian Fainelli says:

====================
net: dsa: mv88e6xxx: fix IPv6

We have had some emails in private over this issue, this is my current
patch set rebased on top of net-next which provides working IPv6 (and
probably other protocols as well) over mv88e6xxx DSA switches.

The problem comes down to mv88e6xxx defaulting to not flood unknown
unicast and multicast datagrams, as they would be by dumb switches,
and as the Linux bridge code does by default.

There is also the issue of IPv6 over a vlan that is transparent to the
bridge; the multicast querier will not reach inside the vlan, and so
the switch can not learn about multicast routing within the vlan.

These flood settings can be disabled via the Linux bridge code if it's
desired to make the switch behave more like a managed switch, eg, by
enabling the multicast querier.  However, the multicast querier
defaults to being disabled which effectively means that by default,
mv88e6xxx switches block all multicast traffic.  This is at odds with
the Linux bridge documentation, and the defaults that the Linux bridge
code adopts.

So, this patch set adds DSA support for Linux bridge flags, adds
mv88e6xxx support for the unicast and multicast flooding flags, and
lastly enables flooding of these frames by default to match the
Linux bridge defaults.

c138806344 net: dsa: enable flooding for bridge ports
Switches work by learning the MAC address for each attached station by
monitoring traffic from each station.  When a station sends a packet,
the switch records which port the MAC address is connected to.

With IPv4 networking, before communication commences with a neighbour,
an ARP packet is broadcasted to all stations asking for the MAC address
corresponding with the IPv4.  The desired station responds with an ARP
reply, and the ARP reply causes the switch to learn which port the
station is connected to.

With IPv6 networking, the situation is rather different.  Rather than
broadcasting ARP packets, a "neighbour solicitation" is multicasted
rather than broadcasted.  This multicast needs to reach the intended
station in order for the neighbour to be discovered.

Once a neighbour has been discovered, and entered into the sending
stations neighbour cache, communication can restart at a point later
without sending a new neighbour solicitation, even if the entry in
the neighbour cache is marked as stale.  This can be after the MAC
address has expired from the forwarding cache of the DSA switch -
when that occurs, there is a long pause in communication.

Our DSA implementation for mv88e6xxx switches disables flooding of
multicast and unicast frames for bridged ports.  As per the above
description, this is fine for IPv4 networking, since the broadcasted
ARP queries will be sent to and received by all stations on the same
network.  However, this breaks IPv6 very badly - blocking neighbour
solicitations and later causing connections to stall.

The defaults that the Linux bridge code expect from bridges are for
unknown unicast and unknown multicast frames to be flooded to all ports
on the bridge, which is at odds to the defaults adopted by our DSA
implementation for mv88e6xxx switches.

This commit enables by default flooding of both unknown unicast and
unknown multicast frames whenever a port is added to a bridge, and
disables the flooding when a port leaves the bridge.  This means that
mv88e6xxx DSA switches now behave as per the bridge(8) man page, and
IPv6 works flawlessly through such a switch.

ca8d4794f6 ipmr: ip6mr: Create new sockopt to clear mfc cache or vifs
Currently the only way to clear the forwarding cache was to delete the
entries one by one using the MRT_DEL_MFC socket option or to destroy and
recreate the socket.

Create a new socket option which with the use of optional flags can
clear any combination of multicast entries (static or not static) and
multicast vifs (static or not static).

Calling the new socket option MRT_FLUSH with the flags MRT_FLUSH_MFC and
MRT_FLUSH_VIFS will clear all entries and vifs on the socket except for
static entries.

If a device does not have a pnetid, users can set a temporary pnetid for
said device in the pnet table. This patch reworks the pnet table to make
it more flexible. Multiple entries with the same pnetid but differing
devices are now allowed. Additionally, the netlink interface now sends
each mapping from pnetid to device separately to the user while
maintaining the message format existing applications might expect. Also,
the SMC data structure for ib devices already has a pnetid attribute.
So, it is used to store the user defined pnetids. As a result, the pnet
table entries are only used for netdevs.

51dcb69de6 net_sched: fix a memory leak in cls_tcindex
(cherry picked from commit 033b228e7f)

When tcindex_destroy() destroys all the filter results in
the perfect hash table, it invokes the walker to delete
each of them. However, results with class==0 are skipped
in either tcindex_walk() or tcindex_delete(), which causes
a memory leak reported by kmemleak.

This patch fixes it by skipping the walker and directly
deleting these filter results so we don't miss any filter
result.

As a result of this change, we have to initialize exts->net
properly in tcindex_alloc_perfect_hash(). For net-next, we
need to consider whether we should initialize ->net in
tcf_exts_init() instead, before that just directly test
CONFIG_NET_CLS_ACT=y.

3d210534cc net_sched: fix a race condition in tcindex_destroy()
(cherry picked from commit 8015d93ebd)

tcindex_destroy() invokes tcindex_destroy_element() via
a walker to delete each filter result in its perfect hash
table, and tcindex_destroy_element() calls tcindex_delete()
which schedules tcf RCU works to do the final deletion work.
Unfortunately this races with the RCU callback
__tcindex_destroy(), which could lead to use-after-free as
reported by Adrian.

Fix this by migrating this RCU callback to tcf RCU work too,
as that workqueue is ordered, we will not have use-after-free.

Note, we don't need to hold netns refcnt because we don't call
tcf_exts_destroy() here.

418e897e07 gso: validate gso_type on ipip style tunnels
Commit 121d57af30 ("gso: validate gso_type in GSO handlers") added
gso_type validation to existing gso_segment callback functions, to
filter out illegal and potentially dangerous SKB_GSO_DODGY packets.

Convert tunnels that now call inet_gso_segment and ipv6_gso_segment
directly to have their own callbacks and extend validation to these.

Another platform requires even longer delay to make the device work

Also shinks the object code size:
