mlxsw: Support for shared buffers in Spectrum-2
Petr says:
Spectrum-2 will be configured with a different set of pools than
Spectrum-1, their sizes will be larger, and the individual quotas will
be different as well. It is therefore necessary to make the shared
buffer module aware of this dependence on chip type, and adjust the
individual tables.
In patch #1, introduce a structure for keeping per-chip immutable and
default values.
In patch #2, structures for keeping current values of SBPM and SBPR
(pool configuration and port-pool quota) are allocated dynamically to
support varying pool counts.
In patches #3 to #7, uses of individual shared buffer configuration
tables are migrated from global definitions to fields in struct
mlxsw_sp_sb_vals, which was introduced above.
Up until this point, the actual configuration is still the one suitable
for Spectrum-1. In patch #8 Spectrum-2 configuration is added.
In patch #9, port headroom configuration is changed to take into account
current recommended value for a 100-Gbps port, and the split factor.
In patch #10, requests for overlarge headroom are rejected. This avoids
potential chip freeze should such overlarge requests be made.

This patch series splits the removal of the switchdev_ops that was

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:

- rebased against net-next/master after Russell's IPv6 changes to DSA
- ignore prepare/commit phase for PRE_BRIDGE_FLAGS since we don't

phase

- differentiate callers not supporting switchdev_port_attr_set() from

====================
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.

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.

net_sched: fix a memory leak in cls_tcindex
(cherry picked from commit
033b228e7f26b29ae37f8bfa1bc6b209a5365e9f)
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.

net_sched: fix a race condition in tcindex_destroy()
(cherry picked from commit
8015d93ebd27484418d4952284fd02172fa4b0b2)
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.

net/mlx5e: Remove wrong and superfluous tc pedit header type check
With recent introduction of flow_rule infrastructure drivers no longer
directly include action headers, so it is no longer possible to use
constants defined in them. Instead, one of flow_rule patches substituted
pedit action header constant with hardcoded value '2' in mlx5
set_pedit_val() function conditional which verifies that header type is in
range of values allowed by pedit action. That conditional is now both
wrong (hardcoded value is '2' but __PEDIT_HDR_TYPE_MAX is 6 in current
version) and superfluous (pedit action already verifies that header type is
in allowed range during init). Remove the described check from mlx5 code.
