ASPM is disabled completely because we've seen different types of
problems in the past. However it seems these problems occurred with
L1 or L1 sub-states only. On all the chip versions I've seen the
acceptable L0s exit latency is 512ns. This should be short enough not
to cause problems. If the actual L0s exit latency of the PCIe link
is bigger than 512ns then the PCI core will disable L0s anyway.
So let's give it a try and disable L1 and L1 sub-states only.

====================
Plug holes in DSA's software bridging support

Changes in v2:
- Make sure that leaving an unoffloaded bridge works well too
- Remove a set but unused variable
- Tweak a commit message

This series addresses some oddities reported by Alvin while he was
working on the new rtl8365mb driver (a driver which does not implement
bridge offloading for now, and relies on software bridging).

First is that DSA behaves, in the lack of a .port_bridge_join method, as
if the operation succeeds, and does not kick off its internal procedures
for software bridging (the same procedures that were written for indirect
software bridging, meaning bridging with an unoffloaded software LAG).

Second is that even after being patched to treat ports with software
bridging as standalone, we still don't get rid of bridge VLANs, even
though we have code to ignore them, that code manages to get bypassed.
This is in fact a recurring issue which was brought up by Tobias
Waldekranz a while ago, but the solution never made it to the git tree.

After debugging with Florian the last time:
https://patchwork.kernel.org/project/netdevbpf/patch/20210320225928.2481575-3-olteanv@gmail.com/
I became very concerned about sending these patches to stable kernels.
They are relatively large reworks, and they are only tested properly on
net-next.

A few commands on my test vehicle which has ds->vlan_filtering_is_global
set to true:

| Nothing is committed to hardware when we add VLAN 100 on a standalone
| port
$ ip link add link sw0p2 name sw0p2.100 type vlan id 100
| When a neighbor port joins a VLAN-aware bridge, VLAN filtering gets
| enabled globally on the switch. This replays the VLAN 100 from
| sw0p2.100 and also installs VLAN 1 from the bridge on sw0p0.
$ ip link add br0 type bridge vlan_filtering 1 && ip link set sw0p0 master br0

| We can see that sw0p2, the standalone port, is now filtering because
| of the bridge
$ ethtool -k sw0p2 | grep vlan
rx-vlan-filter: on [fixed]
| When we make the bridge VLAN-unaware, the 8021q upper sw0p2.100 is
| uncomitted from hardware. The VLANs managed by the bridge still remain
| committed to hardware, because they are managed by the bridge.
$ ip link set br0 type bridge vlan_filtering 0

| And now the standalone port is not filtering anymore.
ethtool -k sw0p2 | grep vlan
rx-vlan-filter: off [fixed]

The same test with .port_bridge_join and .port_bridge_leave commented
out from this driver:

| Not a flinch

$ ip link add br0 type bridge vlan_filtering 1 && ip link set sw0p0 master br0

As explained in commit e358bef7 ("net: dsa: Give drivers the chance
to veto certain upper devices"), the hellcreek driver uses some tricks
to comply with the network stack expectations: it enforces port
separation in standalone mode using VLANs. For untagged traffic,
bridging between ports is prevented by using different PVIDs, and for
VLAN-tagged traffic, it never accepts 8021q uppers with the same VID on
two ports, so packets with one VLAN cannot leak from one port to another.

That is almost fine*, and has worked because hellcreek relied on an
implicit behavior of the DSA core that was changed by the previous
patch: the standalone ports declare the 'rx-vlan-filter' feature as 'on
[fixed]'. Since most of the DSA drivers are actually VLAN-unaware in
standalone mode, that feature was actually incorrectly reflecting the
hardware/driver state, so there was a desire to fix it. This leaves the
hellcreek driver in a situation where it has to explicitly request this
behavior from the DSA framework.

We configure the ports as follows:

- Standalone: 'rx-vlan-filter' is on. An 8021q upper on top of a
  standalone hellcreek port will go through dsa_slave_vlan_rx_add_vid
  and will add a VLAN to the hardware tables, giving the driver the
  opportunity to refuse it through .port_prechangeupper.

- Bridged with vlan_filtering=0: 'rx-vlan-filter' is off. An 8021q upper
  on top of a bridged hellcreek port will not go through
  dsa_slave_vlan_rx_add_vid, because there will not be any attempt to
  offload this VLAN. The driver already disables VLAN awareness, so that
  upper should receive the traffic it needs.

- Bridged with vlan_filtering=1: 'rx-vlan-filter' is on. An 8021q upper
  on top of a bridged hellcreek port will call dsa_slave_vlan_rx_add_vid,
  and can again be vetoed through .port_prechangeupper.

*It is not actually completely fine, because if I follow through
correctly, we can have the following situation:

ip link add br0 type bridge vlan_filtering 0
ip link set lan0 master br0 # lan0 now becomes VLAN-unaware
ip link set lan0 nomaster # lan0 fails to become VLAN-aware again, therefore breaking isolation

This patch fixes that corner case by extending the DSA core logic, based
on this requested attribute, to change the VLAN awareness state of the
switch (port) when it leaves the bridge.

There have been multiple independent reports about
dsa_slave_vlan_rx_add_vid being called (and consequently calling the
drivers' .port_vlan_add) when it isn't needed, and sometimes (not
always) causing problems in the process.

Case 1:
mv88e6xxx_port_vlan_prepare is stubborn and only accepts VLANs on
bridged ports. That is understandably so, because standalone mv88e6xxx
ports are VLAN-unaware, and VTU entries are said to be a scarce
resource.

Otherwise said, the following fails lamentably on mv88e6xxx:

ip link add br0 type bridge vlan_filtering 1
ip link set lan3 master br0
ip link add link lan10 name lan10.1 type vlan id 1
[485256.724147] mv88e6085 d0032004.mdio-mii:12: p10: hw VLAN 1 already used by port 3 in br0
RTNETLINK answers: Operation not supported

This has become a worse issue since commit 9b236d2a ("net: dsa:
Advertise the VLAN offload netdev ability only if switch supports it").
Up to that point, the driver was returning -EOPNOTSUPP and DSA was
reconverting that error to 0, making the 8021q upper think all is ok
(but obviously the error message was there even prior to this change).
After that change the -EOPNOTSUPP is propagated to vlan_vid_add, and it
is a hard error.

Case 2:
Ports that don't offload the Linux bridge (have a dp->bridge_dev = NULL
because they don't implement .port_bridge_{join,leave}). Understandably,
a standalone port should not offload VLANs either, it should remain VLAN
unaware and any VLAN should be a software VLAN (as long as the hardware
is not quirky, that is).

In fact, dsa_slave_port_obj_add does do the right thing and rejects
switchdev VLAN objects coming from the bridge when that bridge is not
offloaded:

	case SWITCHDEV_OBJ_ID_PORT_VLAN:
		if (!dsa_port_offloads_bridge_port(dp, obj->orig_dev))
			return -EOPNOTSUPP;

		err = dsa_slave_vlan_add(dev, obj, extack);

But it seems that the bridge is able to trick us. The __vlan_vid_add
from br_vlan.c has:

	/* Try switchdev op first. In case it is not supported, fallback to
	 * 8021q add.
	 */
	err = br_switchdev_port_vlan_add(dev, v->vid, flags, extack);
	if (err == -EOPNOTSUPP)
		return vlan_vid_add(dev, br->vlan_proto, v->vid);

So it says "no, no, you need this VLAN in your life!". And we, naive as
we are, say "oh, this comes from the vlan_vid_add code path, it must be
an 8021q upper, sure, I'll take that". And we end up with that bridge
VLAN installed on our port anyway. But this time, it has the wrong flags:
if the bridge was trying to install VLAN 1 as a pvid/untagged VLAN,
failed via switchdev, retried via vlan_vid_add, we have this comment:

	/* This API only allows programming tagged, non-PVID VIDs */

So what we do makes absolutely no sense.

Backtracing a bit, we see the common pattern. We allow the network stack
to think that our standalone ports are VLAN-aware, but they aren't, for
the vast majority of switches. The quirky ones should not dictate the
norm. The dsa_slave_vlan_rx_add_vid and dsa_slave_vlan_rx_kill_vid
methods exist for drivers that need the 'rx-vlan-filter: on' feature in
ethtool -k, which can be due to any of the following reasons:

1. vlan_filtering_is_global = true, and some ports are under a
   VLAN-aware bridge while others are standalone, and the standalone
   ports would otherwise drop VLAN-tagged traffic. This is described in
   commit 061f6a50 ("net: dsa: Add ndo_vlan_rx_{add, kill}_vid
   implementation").

2. the ports that are under a VLAN-aware bridge should also set this
   feature, for 8021q uppers having a VID not claimed by the bridge.
   In this case, the driver will essentially not even know that the VID
   is coming from the 8021q layer and not the bridge.

3. Hellcreek. This driver needs it because in standalone mode, it uses
   unique VLANs per port to ensure separation. For separation of untagged
   traffic, it uses different PVIDs for each port, and for separation of
   VLAN-tagged traffic, it never accepts 8021q uppers with the same vid
   on two ports.

If a driver does not fall under any of the above 3 categories, there is
no reason why it should advertise the 'rx-vlan-filter' feature, therefore
no reason why it should offload the VLANs added through vlan_vid_add.

This commit fixes the problem by removing the 'rx-vlan-filter' feature
from the slave devices when they operate in standalone mode, and when
they offload a VLAN-unaware bridge.

The way it works is that vlan_vid_add will now stop its processing here:

vlan_add_rx_filter_info:
	if (!vlan_hw_filter_capable(dev, proto))
		return 0;

So the VLAN will still be saved in the interface's VLAN RX filtering
list, but because it does not declare VLAN filtering in its features,
the 8021q module will return zero without committing that VLAN to
hardware.

This gives the drivers what they want, since it keeps the 8021q VLANs
away from the VLAN table until VLAN awareness is enabled (point at which
the ports are no longer standalone, hence in the mv88e6xxx case, the
check in mv88e6xxx_port_vlan_prepare passes).

Since the issue predates the existence of the hellcreek driver, case 3
will be dealt with in a separate patch.

The main change that this patch makes is to no longer set
NETIF_F_HW_VLAN_CTAG_FILTER unconditionally, but toggle it dynamically
(for most switches, never).

The second part of the patch addresses an issue that the first part
introduces: because the 'rx-vlan-filter' feature is now dynamically
toggled, and our .ndo_vlan_rx_add_vid does not get called when
'rx-vlan-filter' is off, we need to avoid bugs such as the following by
replaying the VLANs from 8021q uppers every time we enable VLAN
filtering:

ip link add link lan0 name lan0.100 type vlan id 100
ip addr add 192.168.100.1/24 dev lan0.100
ping 192.168.100.2 # should work
ip link add br0 type bridge vlan_filtering 0
ip link set lan0 master br0
ping 192.168.100.2 # should still work
ip link set br0 type bridge vlan_filtering 1
ping 192.168.100.2 # should still work but doesn't

As reported by Florian, some drivers look at ds->vlan_filtering in
their .port_vlan_add() implementation. So this patch also makes sure
that ds->vlan_filtering is committed before calling the driver. This is
the reason why it is first committed, then restored on the failure path.

If the driver does not implement .port_bridge_{join,leave}, then we must
fall back to standalone operation on that port, and trigger the error
path of dsa_port_bridge_join. This sets dp->bridge_dev = NULL.

In turn, having a non-NULL dp->bridge_dev when there is no offloading
support makes the following things go wrong:

- dsa_default_offload_fwd_mark make the wrong decision in setting
  skb->offload_fwd_mark. It should set skb->offload_fwd_mark = 0 for
  ports that don't offload the bridge, which should instruct the bridge
  to forward in software. But this does not happen, dp->bridge_dev is
  incorrectly set to point to the bridge, so the bridge is told that
  packets have been forwarded in hardware, which they haven't.

- switchdev objects (MDBs, VLANs) should not be offloaded by ports that
  don't offload the bridge. Standalone ports should behave as packet-in,
  packet-out and the bridge should not be able to manipulate the pvid of
  the port, or tag stripping on egress, or ingress filtering. This
  should already work fine because dsa_slave_port_obj_add has:

	case SWITCHDEV_OBJ_ID_PORT_VLAN:
		if (!dsa_port_offloads_bridge_port(dp, obj->orig_dev))
			return -EOPNOTSUPP;

		err = dsa_slave_vlan_add(dev, obj, extack);

  but since dsa_port_offloads_bridge_port works based on dp->bridge_dev,
  this is again sabotaging us.

All the above work in case the port has an unoffloaded LAG interface, so
this is well exercised code, we should apply it for plain unoffloaded
bridge ports too.

For ports that have a NULL dp->bridge_dev, dsa_port_to_bridge_port()
also returns NULL as expected.

Issue #1 is that we are performing a NULL pointer dereference on brport_dev.

Issue #2 is that these are ports on which switchdev_bridge_port_offload
has not been called, so we should not call switchdev_bridge_port_unoffload
on them either.

Both issues are addressed by checking against a NULL brport_dev in
dsa_port_pre_bridge_leave and exiting early.

advertisements. The information used to populate outgoing advertisement
option headers is now stored separately to avoid rare cases where a more
recent request would overwrite something that had not been sent
yet. While the peers would recover from this, it's better to avoid the
problem in the first place.

Patch 1 moves an advertisement option check under a lock so the changes
made in the next several patches will not introduce a race.

Patches 2-4 make sure ADD_ADDR, ADD_ADDR echo, and RM_ADDR options use

According to the MPTCP_ADD_ADDR_SIGNAL or MPTCP_ADD_ADDR_ECHO flag, build
the ADD_ADDR/ADD_ADDR_ECHO option.

In mptcp_pm_add_addr_signal(), use opts->addr to save the announced
ADD_ADDR or ADD_ADDR_ECHO address.

ADD_ADDR shares pm.addr_signal with RM_ADDR, so after RM_ADDR/ADD_ADDR
has done, we should not clean ADD_ADDR/RM_ADDR's addr_signal.

Use MPTCP_ADD_ADDR_SIGNAL only for the action of sending ADD_ADDR, and
use MPTCP_ADD_ADDR_ECHO only for the action of sending ADD_ADDR echo.

Use msk->pm.local to save the announced ADD_ADDR address only, and reuse
msk->pm.remote to save the announced ADD_ADDR_ECHO address.

To prepare for the next patch.

This patch moved the drop_other_suboptions check from
mptcp_established_options_add_addr() into mptcp_pm_add_addr_signal(), do
it under the PM lock to avoid the race between this check and
mptcp_pm_add_addr_signal().

For this, added a new parameter for mptcp_pm_add_addr_signal() to get
the drop_other_suboptions value. And drop the other suboptions after the
option length check if drop_other_suboptions is true.

Additionally, always drop the other suboption for TCP pure ack:
that makes both the code simpler and the MPTCP behaviour more
consistent.

The ip_options_fragment() only called when iter->offset is equal to zero,
so move it out of loop, and inline 'Copy the flags to each fragment.'
As also, remove the unused parameter in ip_frag_ipcb().

Currently the interface name and PCI address are printed twice, because
netdev_info() is printing this information implicitly already. This results
in messages like the following. remove the duplicated information.

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below.

It has been hand modified to use 'dma_set_mask_and_coherent()' instead of
'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable.
This is less verbose.

It has been compile tested.

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below.

It has been hand modified to use 'dma_set_mask_and_coherent()' instead of
'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable.
This is less verbose.

A message split on 2 lines has been merged.

It has been compile tested.

Merge tag 'wireless-drivers-next-2021-08-22' of git://git.kernel.org/pub/scm/linux/kernel/git/kvalo/wireless-drivers-next

Kalle Valo says:

====================
wireless-drivers-next patches for v5.15

First set of patches for v5.15. This got delayed as I have been mostly
offline for the last few weeks. The biggest change is removal of
prism54 driver, otherwise just smaller changes.

Major changes:

ath5k, ath9k, ath10k, ath11k:

* switch from 'pci_' to 'dma_' API

brcmfmac

* allow per-board firmware binaries

* add support 43752 SDIO device

prism54

* remove the obsoleted driver, everyone should be using p54 driver instead
====================

The usage of these macros has been removed in commit db1a8611
("sunhme: Convert to pure OF driver."). So they can be removed.

This simplifies code and helps for removing the wrappers in
include/linux/pci-dma-compat.h.

The wrappers in include/linux/pci-dma-compat.h should go away.

The patch has been generated with the coccinelle script below.

It has been hand modified to use 'dma_set_mask_and_coherent()' instead of
'pci_set_dma_mask()/pci_set_consistent_dma_mask()' when applicable.
This is less verbose.

A useless "!= 0" has also been removed in a test.

It has been compile tested.
