From: "Hans J. Schultz" <netdev@kapio-technology.com>
Add an intermediate state for clients behind a locked port to allow for
possible opening of the port for said clients. The clients mac address
will be added with the locked flag set, denying access through the port
for the mac address, but also creating a new FDB add event giving
userspace daemons the ability to unlock the mac address. This feature
corresponds to the Mac-Auth and MAC Authentication Bypass (MAB) named
features. The latter defined by Cisco.
Only the kernel can set this FDB entry flag, while userspace can read
the flag and remove it by replacing or deleting the FDB entry.
Locked entries will age out with the set bridge ageing time.

From: "Hans J. Schultz" <netdev@kapio-technology.com>
Add a 'blackhole' fdb flag, ensuring that no forwarding from any port
to a destination MAC that has a FDB entry with this flag on will occur.
The packets will thus be dropped.
When the blackhole fdb flag is set, the 'local' flag will also be enabled
as blackhole entries are not associated with any port.
Thus the command will be alike to:
bridge fdb add MAC dev br0 self local blackhole

From: "Hans J. Schultz" <netdev@kapio-technology.com>
The FID is needed to get hold of which VID was involved in a violation,
thus the need to be able to read the FID.
For convenience the function mv88e6xxx_g1_atu_op() has been used to read
ATU violations, but the function invalidates reading the fid, so to both
read ATU violations without zeroing the fid, and read the fid, functions
have been added to ensure both are done correctly.

From: "Hans J. Schultz" <netdev@kapio-technology.com>
This implementation for the Marvell mv88e6xxx chip series,
is based on handling ATU miss violations occurring when packets
ingress on a port that is locked. The mac address triggering
the ATU miss violation will be added to the ATU with a zero-DPV,
and is then communicated through switchdev to the bridge module,
which adds a fdb entry with the fdb locked flag set. The entry
is kept according to the bridges ageing time, thus simulating a
dynamic entry.
Additionally the driver will set the sticky and masked flags, as
the driver does not support roaming and forwarding from any port
to a locked entry.
As this is essentially a form of CPU based learning, the amount
of locked entries will be limited by a hardcoded value for now,
so as to prevent DOS attacks.

FYI: I have already made updates to this part to use mv88e6xxx_vtu_get()
instead of the walk, which also fixes a problem when vid=0 in this
implementation.

From: "Hans J. Schultz" <netdev@kapio-technology.com>
Verify that the MAC-Auth mechanism works by adding a FDB entry with the
locked flag set, denying access until the FDB entry is replaced with a
FDB entry without the locked flag set.
Add test of blackhole fdb entries, verifying that there is no forwarding
to a blackhole entry from any port, and that the blackhole entry can be
replaced.
Also add a test that verifies that sticky FDB entries cannot roam (this
is not needed for now, but should in general be present anyhow for future
applications).

The sticky selftests are not related to this set and need to be posted
separately.

There are indentation problems in this file. The coding style is to
indent using tabs that are 8 characters deep, not spaces.

This is not how the selftests are usually constructed. We have
h1_create(), h2_create() and switch_create() and the hosts use VRFs via
simple_if_init(). Look at bridge_locked_port.sh, for example.

Move this check to the beginning of the test and instead do:
bridge link set dev $swp1 locked on mab on

Use "bridge fdb get" like in the blackhole test instead of dumping the

It is quite pointless to check that an entry cannot roam to a port that
has learning disabled... Need:

First check that the entry roamed to $swp2 using "bridge fdb get", then
check that the locked flag is not set on it.

Need to delete the FBD entry from $swp2.

Why this helper needs a device, but check_locked_port_support() does
not? Please change this helper to work like check_locked_port_support().

It seems that the output of 'bridge fdb get' does not respect the dev it
is given as input and outputs the (MAC,vlan) when found on another
dev...

Try a allmodconfig build on latest net-next, seems broken.

I have all different switch drivers enabled and I see no compile
warnings or errors. I guess I will get a robot update if that is the
case, but please be specific as to what does not build.

Just do what I told you - rebase on net-next, allmodconfig.

The maintainers simply don't have time to hold everyone by the hand.
Sometimes I wish it was still okay to yell at people who post code
which does not build. Oh well.

Obviously my method of selecting all switchcore drivers with sub-options
under menuconfig was not sufficient, and I didn't know of the
allmodconfig option, otherwise I would have used it.
So the question is if I should repost the fixed patch-set or I need to
make a new version?
Anyhow I hope that there will not be problems when running the
selftests, as I have not been able to do so with my system, so there can
be more that needs to be changed.
If anyone needs it, here is the compile fix patch:

You can see build issues on patchwork:

A new fixed version (v7) is required, but wait for this version to be
reviewed first.

It's not really acceptable to post tests that you haven't run... What
exactly is the issue? You should be able to run the tests with veth
pairs in a VM.

Do not point people to patchwork checks, please. It will only encourage
people to post stuff they haven't build tested themselves.
It's documented:

Only people who helped write the code and maintain the infra can decide
how to use it which means me, Kees, or Hangbin. Please and thank you :S

Did you read my reply? I specifically included this link so that you
won't tell me I'm encouraging people to build test their patches by
posting to netdev.

Yeah, I noticed the link after, but I think my point stands.
You show someone the patchwork checks and then at the end of the "also"
section put a link on how it's not okay to abuse it. Not a clear enough
instruction.
*never* point people to the patchwork checks, *please*

It is only the blackhole test that I have not been able to run as is,
but I have stepped it manually as far as I could.
My environment has changed lately and in that context the building of
the selftests fails and I don't know why,I just get some error
messagesabout missing header files, and setting up a whole system like
f.ex. linuxfromscratch with the necessary libs and tools to run it in a
VM is too time consuming a task at the moment.
If there is some freely available system for the purpose out there
besides my own system based on Buildroot that does not work now, please
let me know...

First there is an issue with alsa missing for some mixer tests, then
there is several reports of sys/capability.h missing, and then just
really many obscure problems that look like wrong lib versions are in
place. Here is some of the long log of errors etc... :(
