* [PATCH net-next] net: ethernet: ti: cpsw: enable HWTSTAMP_FILTER_PTP_V1_L4_EVENT filter
From: Grygorii Strashko @ 2017-06-08 18:51 UTC (permalink / raw)
To: David S. Miller, netdev, Sekhar Nori
Cc: linux-kernel, linux-omap, Grygorii Strashko
CPSW driver supports PTP v1 messages, but for unknown reasons this filter
is not advertised. As result,
./tools/testing/selftests/networking/timestamping/timestamping utility
can't be used for testing of CPSW RX timestamping with option
SOF_TIMESTAMPING_RX_HARDWARE, because it uses
HWTSTAMP_FILTER_PTP_V1_L4_SYNC filter.
Hence, fix it by advertising HWTSTAMP_FILTER_PTP_V1_L4_XXX filters
in CPSW driver.

This patchset brings no functional changes. It is a first step in a
bigger cosmetics change to the driver. It provides macros and polishes
data types and chip operations.
The next patchs will only prefix and document the port registers macros.
Vivien Didelot (7):
net: dsa: mv88e6xxx: provide printing macros
net: dsa: mv88e6xxx: add egress mode enumeration
net: dsa: mv88e6xxx: use bridge state values
net: dsa: mv88e6xxx: do not prefix ops with g1
net: dsa: mv88e6xxx: rework pause limit operation
net: dsa: mv88e6xxx: rework jumbo size operation

* [PATCH net-next 1/7] net: dsa: mv88e6xxx: provide printing macros
From: Vivien Didelot @ 2017-06-08 19:04 UTC (permalink / raw)
To: netdev
Cc: linux-kernel, kernel, David S. Miller, Florian Fainelli,

In-Reply-To: <20170608190445.24443-1-vivien.didelot@savoirfairelinux.com>
The mv88e6xxx driver accesses a port's netdev mostly for printing.
This is bad for 2 reasons: DSA and CPU ports do not have a netdev
pointer; it doesn't give us a correct picture of why a DSA driver might
need to access a port's netdev.
Introduce mv88e6xxx_{dbg,err,warn} macros to print messages with a
prefix containing the real switch name (not the compatible one),
as well as the switch and port indexes.
These are examples of output in dmesg with this patch:
[ 103.488407] Marvell 88E6352 1.6: DefaultVID set to 42
[ 103.562586] Marvell 88E6185 2.0: 802.1QMode set to Secure
[ 103.559690] Marvell 88E6390X 1.2: PortState set to Forwarding

* [PATCH net-next 2/7] net: dsa: mv88e6xxx: add egress mode enumeration
From: Vivien Didelot @ 2017-06-08 19:04 UTC (permalink / raw)
To: netdev

Andrew Lunn, Vivien Didelot
In-Reply-To: <20170608190445.24443-1-vivien.didelot@savoirfairelinux.com>
As for the frame mode, add a mv88e6xxx_egress_mode enumeration instead
of a 16-bit register mask.

Reuse the BR_STATE_* values to abstract a port STP state value.
This provides shorter names and better control over the DSA switch
operation call.

The mv88e6xxx_ops describe functionalities, regardless their locations
(which can be Global1, Global2, or whatever register set.)
Rename the g1_set_cpu_port and g1_set_egress_port ops to set_cpu_port
and set_egress_port. No functional changes.

* [PATCH net-next 5/7] net: dsa: mv88e6xxx: rework pause limit operation
From: Vivien Didelot @ 2017-06-08 19:04 UTC (permalink / raw)
To: netdev
Cc: linux-kernel, kernel, David S. Miller, Florian Fainelli,
Andrew Lunn, Vivien Didelot
In-Reply-To: <20170608190445.24443-1-vivien.didelot@savoirfairelinux.com>
All Marvell chips supporting Pause frames limiting use 1-byte value for
input and output.
Old chips have both bytes adjacent in a 16-bit register. New ones have
an indirect table using 8-bit data.
The mv88e6xxx library functions (such as in port.c) must not contain
driver logic, but only generic helpers. This patch changes the
port_pause_config operation for port_pause_limit taking two u8 arguments
for input and output limits. There is no functional changes.

* [PATCH net-next 6/7] net: dsa: mv88e6xxx: rework jumbo size operation
From: Vivien Didelot @ 2017-06-08 19:04 UTC (permalink / raw)
To: netdev
Cc: linux-kernel, kernel, David S. Miller, Florian Fainelli,
Andrew Lunn, Vivien Didelot
In-Reply-To: <20170608190445.24443-1-vivien.didelot@savoirfairelinux.com>
Marvell chips have a Jumbo Mode to set the maximum frame size (MTU).
The mv88e6xxx_ops structure is meant to contain generic functionalities,
no driver logic. Change port_jumbo_config to port_set_jumbo_size setting
the mode from a given maximum size value.
There is no functional changes since we still use 10240 bytes.
At the same time, correctly clear all Jumbo Mode bits before writing.

What could it prevent us from doing, though? It's basically equivalent to giving
BPF an opcode that casts a pointer to a u64, which of course is only allowed if
allow_ptr_leaks is true. And since we don't feed any knowledge about the pointer
into the verifier, it's just like any other way of filling a register with
arbitrary, unknown bits.
I can fully appreciate why you're being cautious, what with uapi and all. But I
don't think there's any actual problem here. Open to being convinced, though.

Don't we though?

(Thinking out loud...)
What would be really nice is a way to propagate limits backwards as well as
forwards, so that the verifier can say "when I tested this branch, I used
this part of the state, I read four bytes past this pointer". Then when it
wants to prune, it can say "well, the state this time isn't as strong, but
it still satisfies everything I actually used".
But that sounds like it would be very hard indeed to do.
Maybe with the basic-block DAG stuff David's been talking about, we could
find all the paths that reach a block, and take the union of their states,
and then run through the block feeding it that combined state. But that
could reject code that relies on correlation of the state (i.e. if r1 != 0
then r2 is valid ptr I can access, etc) so would still need the 'walk with
each individual state' as a fallback. Though at least you'd have all the
states at once so you could find out which ones were subsumed, instead of
hoping you get to them in the right order.

Hi Florian
I don't like this, on multiple levels.
My wan port typically never has more than 40Mbps of traffic on it. So
dedicating a whole 1Gbps ethernet to it makes no sense. I want to
share eth1 bandwidth with the wan port, and some of the other
ports. Meaning i would have to add eth1 to br-lan as well as
br-wan. Does the bridge allow that? And what sort of hacks do you have
to allow a port to be added to a bridge, but not used by the bridge?
And what is the point of br-wan? It only has one real port in it. So
i'm adding per-packet overhead which i don't need, just in order to
signal to the hardware how it should statically route cpu traffic for
a port.
Now say i have one of the bigger marvell switches, with 11 ports, in
an industrial application. I setup 3 or 4 bridges. I then need to add
eth0 and eth1 to two different bridges. And say i use some ports
without a bridge. How do i configure them?
And how do i dump the current mapping?
For me, this is the wrong architecture. What CPU port is used should
be a port property, not a bridge property. I think we should use
devlink. Add commands to dump the current mapping, and set it.

Hi Vivien
I agree with the principle, but wonder about the naming. We have some
stuff which is not per port, but at the chip level. It would be nice
to have a similar set of helpers, but which only take chip. So maybe
we want to call these mv88e6xxx_port_{dbg, err, warn} and later add
mv88e6xxx_chip_{dbg, err, warn}.

Yes, we could check every byte of the stack within the range [buf, buf+63]
is a STACK_MISC and if so allow it. But since this is not supported by the
existing code (so it's not a regression), I'd prefer to leave that for a
future patch - this one is quite big enough already ;-)

In the end I settled on adding a helper
struct tnum tnum_cast(struct tnum a, u8 size);
since I have a bunch of other places that cast things to 32 bits.

Good idea, I'll do that.

It looks like the only place this gets recorded is as "processed %d insns"
in the log_buf. Is there a convenient way to get at this, or am I going
to have to make bpf_verify_program grovel through the log sscanf()ing for
a matching line?

This is AN example of how to configure a port grouping based on John's
example and use case, not THE only example ;) The idea is obviously that
you can define association between user-facing ports and CPU ports as
you see fit, the idea is to use bridge to do that association because
that's already what controls VLAN membership and forwarding.

No, it has two ports in it, adding eth1 is necessary do define the VLAN
membership and forwarding rules, when eth1 is added we resolve the CPU
port this corresponds to in the switch and we use that to define the
forwarding decision between ports.
The overhead per-packet is extremely limited because the first thing
br_handle_frame() will do is see that eth1 is a DSA master network
device and pass packets back up the stack for processing through dst->rcv().

If you don't add your conduit interface to the bridge, then the default
CPU interface (which could be left to the driver to decide which one is
relevant) gets used and things work as expected. When you add a DSA
master network device to the bridge, only then do we use that
information to refine the forwarding decision and map to the appropriate
port vectors. Doing this becomes necessary if you create a second (or
more) bridge to isolate a group of ports.

You look at both (or more) bridges' members, what's wrong or even any
different from what happens today?

In premise I agree, although just like we need a bridge today to
configure VLAN memberships, it did not seem to me like a big stretch to
use a bridge to configure which CPU port you want.
