Commit Message

Ioana Ciornei Nov. 4, 2020, 4:57 p.m. UTC
From: Ioana Ciornei <ioana.ciornei@nxp.com>

Until now, the DPAA2 switch was not capable to properly setup it's
switching domains depending on the existence, or lack thereof, of a
upper bridge device. This meant that all switch ports of a DPSW object
were switching by default even though they were not under the same
bridge device.

Another issue was the inability to actually add the CPU in the flooding
domains (broadcast, unknown unicast etc) of a particular switch port.
This meant that a simple ping on a switch interface was not possible
since no broadcast ARP frame would actually reach the CPU queues.

This patch tries to fix exactly these problems by:

* Creating and managing a FDB table for each flooding domain. This means
  that when a switch interface is not bridged it will use it's own FDB
  table. While in bridged mode all DPAA2 switch interfaces under the
  same upper will use the same FDB table, thus leverage the same FDB
  entries.

* Adding a new MC firmware command - dpsw_set_egress_flood() - through
  which the driver can setup the flooding domains as needed. For
  example, when the switch interface is standalone, thus not in a
  bridge with any other DPAA2 switch port, it will setup it's broadcast
  and unknown unicast flooding domains to only include the control
  interface (the queues that reach the CPU and the driver can dequeue
  from). This flooding domain changes when the interface joins a bridge
  and is configured to include, beside the control interface, all other
  DPAA2 switch interfaces.

None of the occurrences of "it's" in the commit message is grammatically
correct. So please s/it's/its/g.

netdev_for_each_lower_dev calls netdev_lower_get_next which has this in
the comments:

 * The caller must hold RTNL lock or
 * its own locking that guarantees that the neighbour lower
 * list will remain unchanged.

Does that hold true for all callers, if you put ASSERT_RTNL() here?

And this is the reason why VLAN-unaware mode is unsupported, right? No
hit on any VLAN rule => no FDB table selected for the packet. What is
the default action for misses on VLAN rules? Drop or some default FDB
ID?

Hmmm, so in dpaa2_switch_port_get_fdb_id you say:

	/* If part of a bridge, use the FDB of the first dpaa2 switch interface
	 * to be present in that bridge
	 */

So let's say there is a br0 with swp3 and swp2, and a br1 with swp4.
IIUC, br0 interfaces (swp3 and swp2) will have an fdb_id of 3 (due to
swp3 being added first) and br1 will have an fdb_id of 4 (due to swp4).

When swp3 leaves br0, will this cause the fdb_id of swp2 to change?
I expect the answer is yes, since otherwise swp2 and swp3 would keep
forwarding packets to one another. Is this change graceful?

For example, if you add a static FDB entry to swp2 prior to removing
swp3, I would expect the fdb_id of swp2 to preserve that static FDB
entry, even if swp2 now gets moved to a different fdb_id. Similarly,
flooding settings, everything is preserved when the fdb_id changes?

The flip side of that is: what happens if you add an FDB entry to swp2,
then you remove swp2 from br0 and move it to br1? Will swp4 (which was
already in br1) see that static FDB entry in hardware, even if the
software bridge br1 hasn't notified you about it?

Basically, my question boils down to: why is there so little activity in
dpaa2_switch_port_bridge_leave.

No, not for all. The probe path uses this as well and is not protected
by the rtnl lock.

Good point, I'll add an explicit lock/unlock. Thanks.

Yes, exactly.

The default action for misses on the VLAN table is drop. For example, if
a VLAN tagged packet is received on a switch interface which does not
have an upper VLAN interface with that VLAN id (thus the
.ndo_vlan_rx_add_vid() is not called) , the packet will get dropped
immediately.

The learning flag is per FDB table, thus it's configuration now has to
take into account the corresponding FDB of an interface.

Actually, being able to configure the learning flag is somewhat of an
inconvenience since this would also change the learning behavior of all
the other switch ports under the same bridge, all this without the
bridge actually learning of this change.

I think I will just remove the code that handles changing the learning
status at the moment, until I can make changes in the MC firmware so
that this flag is indeed per port.

Yes, the fdb_id of swp2 will change but, as the code is now, it will
only change for new FDB static entries added or any new VLANs
installed.

No, moving static FDB entries on a bridge leave/join does not happen
now.

As you said, moving any FDB entry from one FDB table to another one
would be a problem since the software bridge br1 would not be notified
of any of these new entries.

Taking all the above into account, what I think the code should do if
swp2, for example, leaves a bridge is to:
 - update all VLAN entries installed for swp2 so that on a hit it would
   lead the packet into the new FDB table.
 - all static FDB entries already installed on swp2 should be removed
   from the FDB table corresponding to the previous bridge that the port
   was under.
