In cops_probe1(), there is a write to dev->base_addr after requesting an
interrupt line and registering the interrupt handler cops_interrupt().
The handler might be called in parallel to handle an interrupt.
cops_interrupt() tries to read dev->base_addr leading to a potential
data race. So write to dev->base_addr before calling request_irq().

The shared frame buffer of the SJA1110 is larger than that of SJA1105,
which is natural due to the fact that there are more ports.
Introduce yet another property in struct sja1105_info which encodes the
maximum number of 128 byte blocks that can be used for frame buffers.

The SJA1110 policer array is similar in layout with SJA1105, except it
contains one multicast policer per port at the end.
Detect the presence of multicast policers based on the maximum number of
supported L2 Policing Table entries, and make those policers have a
shared index equal to the port's default policer. Letting the user
configure these policers is not supported at the moment.

Due to the fact that the port count is different, some static config
tables have a different number of elements in SJA1105 compared to
SJA1110. Such an example is the L2 Policing table, which has 45 entries
in SJA1105 (one per port x traffic class, and one broadcast policer per
port) and 110 entries in SJA1110 (one per port x traffic class, one
broadcast and one multicast policer per port).
Similarly, the MAC Configuration Table, the L2 Forwarding table, all
have a different number of elements simply because the port count is
different, and although this can be accounted for by looking at
ds->ports, the policing table can't because of the presence of the extra
multicast policers.
The common denominator for the static config initializers for these
tables is that they must set up all the entries within that table.
So the simplest way to account for these differences in a uniform manner
is to look at struct sja1105_table_ops::max_entry_count. For the sake of
uniformity, this patch makes that change also for tables whose number of
elements did not change in SJA1110, like the xMII Mode Parameters, the
L2 Lookup Parameters, General Parameters, AVB Parameters (all of these
are singleton tables with a single entry).

There are two distinct code paths which enter sja1105_clocking.c, one
through sja1105_clocking_setup() and the other through
sja1105_clocking_setup_port():
sja1105_static_config_reload sja1105_setup
| |
| +------------------+
| |
v v
sja1105_clocking_setup sja1105_adjust_port_config
| |
v |
sja1105_clocking_setup_port <------------------+
As opposed to SJA1105, the SJA1110 does not need any configuration of
the Clock Generation Unit in order for xMII ports to work. Just RGMII
internal delays need to be configured, and that is done inside
sja1105_clocking_setup_port for the RGMII ports.
So this patch introduces the concept of a "reserved address", which the
CGU configuration functions from sja1105_clocking.c must check before
proceeding to do anything. The SJA1110 will have reserved addresses for
the CGU PLLs for MII/RMII/RGMII.
Additionally, make sja1105_clocking_setup() a function pointer so it can
be overridden by the SJA1110. Even though nothing port-related needs to
be done in the CGU, there are some operations such as disabling the
watchdog clock which are unique to the SJA1110.

The sja1105 driver will gain support for the next-gen SJA1110 switch,
which is very similar except for the fact it has more than 5 ports.
So we need to replace the hardcoded SJA1105_NUM_PORTS in this driver
with ds->num_ports. This patch is as mechanical as possible (save for
the fact that ds->num_ports is not an integer constant expression).

When running this sequence of operations:
ip link add br0 type bridge vlan_filtering 1
ip link set swp4 master br0
bridge vlan add dev swp4 vid 1
We observe the traffic sent on swp4 is still untagged, even though the
bridge has overwritten the existing VLAN entry:
port vlan ids
swp4 1 PVID
br0 1 PVID Egress Untagged
This happens because we didn't consider that the 'bridge vlan add'
command just overwrites VLANs like it's nothing. We treat the 'vid 1
pvid untagged' and the 'vid 1' as two separate VLANs, and the first
still has precedence when calling sja1105_build_vlan_table. Obviously
there is a disagreement regarding semantics, and we end up doing
something unexpected from the PoV of the bridge.
Let's actually consider an "existing VLAN" to be one which is on the
same port, and has the same VLAN ID, as one we already have, and update
it if it has different flags than we do.
The first blamed commit is the one introducing the bug, the second one
is the latest on top of which the bugfix still applies.

One thing became visible when writing the blamed commit, and that was
that STP and PTP frames injected by net/dsa/tag_sja1105.c using the
deferred xmit mechanism are always classified to the pvid of the CPU
port, regardless of whatever VLAN there might be in these packets.
So a decision needed to be taken regarding the mechanism through which
we should ensure that delivery of STP and PTP traffic is possible when
we are in a VLAN awareness mode that involves tag_8021q. This is because
tag_8021q is not concerned with managing the pvid of the CPU port, since
as far as tag_8021q is concerned, no traffic should be sent as untagged
from the CPU port. So we end up not actually having a pvid on the CPU
port if we only listen to tag_8021q, and unless we do something about it.
The decision taken at the time was to keep VLAN 1 in the list of
priv->dsa_8021q_vlans, and make it a pvid of the CPU port. This ensures
that STP and PTP frames can always be sent to the outside world.
However there is a problem. If we do the following while we are in
the best_effort_vlan_filtering=true mode:
ip link add br0 type bridge vlan_filtering 1
ip link set swp2 master br0
bridge vlan del dev swp2 vid 1
Then untagged and pvid-tagged frames should be dropped. But we observe
that they aren't, and this is because of the precaution we took that VID
1 is always installed on all ports.
So clearly VLAN 1 is not good for this purpose. What about VLAN 0?
Well, VLAN 0 is managed by the 8021q module, and that module wants to
ensure that 802.1p tagged frames are always received by a port, and are
always transmitted as VLAN-tagged (with VLAN ID 0). Whereas we want our
STP and PTP frames to be untagged if the stack sent them as untagged -
we don't want the driver to just decide out of the blue that it adds
VID 0 to some packets.
So what to do?
Well, there is one other VLAN that is reserved, and that is 4095:
$ ip link add link swp2 name swp2.4095 type vlan id 4095
Error: 8021q: Invalid VLAN id.
$ bridge vlan add dev swp2 vid 4095
Error: bridge: Vlan id is invalid.
After we made this change, VLAN 1 is indeed forwarded and/or dropped
according to the bridge VLAN table, there are no further alterations
done by the sja1105 driver.

Unlike other drivers which pretty much end their .probe() execution with
dsa_register_switch(), the sja1105 does some extra stuff. When that
fails with -ENOMEM, the driver is quick to return that, forgetting to

At the beginning of the sja1105_dynamic_config.c file there is a diagram
of the dynamic config interface layout:
packed_buf
|
V
+-----------------------------------------+------------------+
| ENTRY BUFFER | COMMAND BUFFER |
+-----------------------------------------+------------------+
<----------------------- packed_size ------------------------>
So in order to pack/unpack the command bits into the buffer,
sja1105_vl_lookup_cmd_packing must first advance the buffer pointer by
the length of the entry. This is similar to what the other *cmd_packing
functions do.
This bug exists because the command packing function for P/Q/R/S was
copied from the E/T generation, and on E/T, the command was actually
embedded within the entry buffer itself.

The current internal sja1105 driver API is optimized for retrieving many
statistics counters at once. But the switch does not do atomic snapshotting
for them anyway.
In case we start reporting the hardware port counters through
ndo_get_stats64 as well, not just ethtool, it would be good to be able
to read individual port counters and not all of them.
Additionally, since Arnd Bergmann's commit ae1804de93f6 ("dsa: sja1105:
dynamically allocate stats structure"), sja1105_get_ethtool_stats
allocates memory dynamically, since struct sja1105_port_status was
deemed to consume too much stack memory. That is not ideal.
The large structure is only needed because of the burst read.
If we read statistics one by one, we can consume less memory, and
we can avoid dynamic allocation.
Additionally, latency-sensitive interfaces such as PTP operations (for
phc2sys) might suffer if the SPI mutex is being held for too long, which
happens in the case of SPI burst reads. By reading counters one by one,
we give a chance for higher priority processes to preempt and take the
SPI bus mutex for accessing the PTP clock.
