[PATCH net-next v2 4/5] net: dsa: mv88e6xxx: exclude all ports in new VLAN
Now that the DSA core adds the CPU and DSA ports itself to the new VLAN entry, there is no need to include them as members of this VLAN when initializing a new VTU entry. As of now, initialize a new VTU entry with all ports excluded.

[PATCH net-next v2 0/5] net: dsa: add cross-chip VLAN support
The current code in DSA does not support cross-chip VLAN. This means
that in a multi-chip environment such as this one (similar to ZII Rev B)
[CPU] (mdio)
(eth0) | : : :
_|_______
[__sw0__]--[__sw1__]--[__sw2__]
| | || | || | |
v v vv v vv v v
p1 p2 p3 p4 p5 p6 p7 p8 p9
adding a VLAN to p9 won't be enough to reach the CPU, until at least one
port of sw0 and sw1 join the VLAN as well and become aware of the VID.
This patchset makes the DSA core program the VLAN on the CPU and DSA
links itself, which brings seamlessly cross-chip VLAN support to DSA.
With this series applied*, the hardware VLAN tables of a 3-switch setup
look like this after adding a VLAN to only one port of the end switch:
# cat /sys/class/net/br0/bridge/default_pvid
42
# cat /sys/kernel/debug/mv88e6xxx/sw{0,1,2}/vtu
# ip link set up master br0 dev lan6

4210 x x x x x = =

4210 u x x x x x x x x =
('x' is excluded, 'u' is untagged, '=' is unmodified DSA and CPU ports.)
Completely removing a VLAN entry (which is currently the responsibility
of drivers anyway) is not supported yet since it requires some caching.

In a multi-chip switch fabric, it is currently the responsibility of the

We want the DSA drivers to be stupid and the DSA core being the one

Make the DSA core program the CPU and DSA ports as part of the VLAN.
This makes all chips of the data path to be aware of VIDs spanning the

[PATCH net-next v2 2/5] net: dsa: check VLAN capability of every switch
Now that the VLAN object is propagated to every switch chip of the
switch fabric, we can easily ensure that they all support the required
VLAN operations before modifying an entry on a single switch.
To achieve that, remove the condition skipping other target switches,
and add a bitmap of VLAN members, eventually containing the target port,
if we are programming the switch target.
This will allow us to easily add other VLAN members, such as the DSA or
CPU ports (to introduce cross-chip VLAN support) or the other port
members if we want to reduce hardware accesses later.

[PATCH net-next v2 5/5] net: dsa: mv88e6xxx: do not skip ports on VLAN del
The mv88e6xxx driver currently tries to be smart and remove by itself a
VLAN entry from the VTU when the driven switch sees no user ports as
members of the VLAN.
This is bad in a multi-chip switch fabric, since a chip in between
others may have no bridge port members, but still needs to be aware of
the VID in order to correctly pass frames in the data path.
Now that the DSA core explicitly manages DSA and CPU ports, do not skip
them when checking remaining VLAN members.

Hum there is a small functional change though: if one interconnected switch of the fabric does not support the VLAN operations, -EOPNOTSUPP is returned (even though the target switch is VLAN capable.)

I can remove only the dsa_is_{cpu,dsa}_port condition above, this will

[PATCH net-next 2/5] net: dsa: check VLAN capability of every switch
Now that the VLAN object is propagated to every switch chip of the
switch fabric, we can easily ensure that they all support the required
VLAN operations before modifying an entry on a single switch.
To achieve that, remove the condition skipping other target switches,
and add a bitmap of VLAN members, eventually containing the target port,
if we are programming the switch target.
This will allow us to easily add other VLAN members, such as the DSA or
CPU ports (to introduce cross-chip VLAN support) or the other port
members if we want to reduce hardware accesses later.

[PATCH net-next] net: dsa: mv88e6xxx: fix 6085 frame mode masking
The register bits used for the frame mode were masked with DSA (0x1)
instead of the mask value (0x3) in the 6085 implementation of
port_set_frame_mode. Fix this.

[PATCH net-next 1/5] net: dsa: mv88e6xxx: rename chip header
The mv88e6xxx.h is meant to contains the chip structures and data.
Rename it to chip.h, as for other source/header pairs of the driver.
At the same time, ensure that relative header inclusions are separated
by a newline and sorted alphabetically.

[PATCH net-next v3 5/5] net: dsa: factor skb freeing on xmit
As of a86d8becc3f0 ("net: dsa: Factor bottom tag receive functions"),
the rcv caller frees the original SKB in case or error.
Be symmetric with that and make the xmit caller do the same.
At the same time, fix the checkpatch NULL comparison check:
CHECK: Comparison to NULL could be written "!nskb"

[PATCH net-next v3 3/5] net: dsa: remove dsa_uses_tagged_protocol
Since dev->dsa_ptr is a pointer to a dsa_switch_tree, there is no need
to have another inline helper just to check rcv.
Remove dsa_uses_tagged_protocol and check dsa_ptr && dsa_ptr->rcv
together at the same time.

The rcv caller frees the original SKB on error, as of a86d8becc3f0
("net: dsa: Factor bottom tag receive functions").
It'd be nice if we could make both xmit and rcv symmetric, and limit the
tagging implementations to only do their real job: tag/untag an SKB with
the destination/source port.
Thanks,
Vivien

This looks confusing to me. What DSA calls an "upstream" port for the
moment is the port which goes to the CPU interface.
CPU0 (eth0)
|
| sw0 sw1 sw2
[p0 p1 p2]--[p0 p1 p2]--[p0 p1 p2]
| | | |
eth1 eth2eth3 eth4
So in the example above, sw1p0 is an upstream port, but sw1p2 is not.
This is why dsa_upstream_port makes use of ds->rtable.

I'm a bit confused why we need all these references to net devices. We
now have ds->master_netdev, dst->master_netdev, dp->ethernet and
p->master...
Wouldn't it be simpler if we only had dp->ethernet (or whichever more
explicit name) for the conduit interface used to send/receive frames?
Maybe I am missing something, in which case I'm sorry in advance.
Thanks,

[PATCH net-next v2 6/6] net: dsa: factor skb freeing on xmit
The taggers are currently responsible to free the original SKB if they
made a copy of it, or in case of error.
This patch simplifies this by freeing the original SKB in the
dsa_slave_xmit caller, but only if an error (NULL) is returned.
It is still the responsibility of the tagger to free the original SKB if
it returned a copy of it.
At the same time, fix the checkpatch NULL comparison check:
CHECK: Comparison to NULL could be written "!nskb"

[PATCH net-next v2 3/6] net: dsa: remove dsa_uses_tagged_protocol
Since dev->dsa_ptr is a pointer to a dsa_switch_tree, there is no need
to have another inline helper just to check rcv.
Remove dsa_uses_tagged_protocol and check dsa_ptr && dsa_ptr->rcv
together at the same time.

OK! That was interesting. I'm dropping the first 2 patches.

Thanks for the explanation, this wasn't obvious to me at all. So inline
is mandatory here. Would a dereference like "!!dst->tag_ops->rcv" have
an significant impact on performance?

It felt weird to copy structure members like this and not at least reusing the dsa_device_ops structure. Thanks, Vivien

I think it was written such way to be symmetrical with the xmit implementation, where the trailer tagger does reallocate the skb. I would say that keeping the symmetry is simpler from the point of view of the tagging implementations, but I don't have strong opinion here. Thanks, Vivien
[PATCH net-next 7/7] net: dsa: factor skb freeing on xmit
The taggers are currently responsible to free the original SKB if they
made a copy of it, or in case of error.
This patch simplifies this by freeing the original SKB in the
dsa_slave_xmit caller if it differs from the return SKB (copy or NULL.)
At the same time, fix the checkpatch NULL comparison check:
CHECK: Comparison to NULL could be written "!nskb"

[PATCH net-next 3/7] net: dsa: remove unused arguments of tagger rcv
The struct dsa_device_ops defines the rcv function with 2 unused
arguments struct packet_type *pt, and struct net_device *orig_dev.
This patch removes them from the definition and implementations.

[PATCH net-next 0/7] net: dsa: tagger simplification
The DSA layer has a dsa_device_ops structure containing two members to tag and untag the proprietary switch header, called xmit and rcv. The switch tree and slave private structures respectively hold a useless copy of the rcv and xmit functions. The tagging implementations use useless goto labels and only the rcv caller (partially) handles the SKB freeing. The rcv function also contains unused arguments. This patchset removes the copy of rcv and xmit functions, the unused arguments of the rcv signature and the useless labels, and handles freeing of the SKB in the xmit caller. Vivien Didelot (7): net: dsa: hide dsa_uses_tagged_protocol code net: dsa: remove useless rcv copy in DSA tree net: dsa: remove unused arguments of tagger rcv net: dsa: free orig skb on rcv if reallocated net: dsa: remove useless goto label in tagger rcv net: dsa: remove useless copy of tagger xmit net: dsa: factor skb freeing on xmit include/net/dsa.h | 9 + net/dsa/dsa.c | 12 +--- net/dsa/dsa2.c| 2 -- net/dsa/dsa_priv.h| 7 +-- net/dsa/legacy.c | 2 -- net/dsa/slave.c | 6 +++--- net/dsa/tag_brcm.c| 21 ++--- net/dsa/tag_dsa.c | 25 - net/dsa/tag_edsa.c| 25 - net/dsa/tag_lan9303.c | 8 ++-- net/dsa/tag_mtk.c | 19 +-- net/dsa/tag_qca.c | 21 ++--- net/dsa/tag_trailer.c | 18 +- 13 files changed, 54 insertions(+), 121 deletions(-) -- 2.13.0

[PATCH net-next] net: dsa: mv88e6xxx: handle SERDES error appropriately
mv88e6xxx_serdes_power returns an error, so no need to print an error
message inside of it. Rather print it in its caller when the error is
ignored, which is in the mv88e6xxx_port_disable void function.
Catch and return its error in the counterpart mv88e6xxx_port_enable.
Fixes: 04aca9938255 ("dsa: mv88e6xxx: Enable/Disable SERDES on port

Similarly to the VTU, PVT and ATU setup, provide a mv88e6xxx_phy_setup
helper which wraps mv88e6xxx_ppu_enable, so that no more PPU-related
functions are exposed outside of phy.c.
Thus make mv88e6xxx_ppu_enable static.

[PATCH net-next 0/3] net: dsa: mv88e6xxx: PHY nitpicks
This patchset isolates more PPU code into phy.c and makes distinction between PHY Registers read and write implementations vs. generic PHY routines.

[PATCH net-next 2/3] net: dsa: mv88e6xxx: rename PHY PPU accessors
Make it clear that mv88e6xxx_phy_ppu_{read,write} are an implementation
of the .phy_{read,write} operations, by renaming them with the mv88e6185
prefix, since 88E6185 it is the reference switch model supported in an
upstream board (ZII Dev Rev B), which makes use of them.
Distinguish the signatures of implementation specific and generic PHY
functions in the phy.h header.

Respect the implicit naming convention used in all register sets
specific files, by renaming the mv88e6xxx_ppu_* functions with the
mv88e6xxx_phy_* prefix.
This is simply a s/xxx_ppu/xxx_phy_ppu/ substitution.

[PATCH net-next] net: dsa: remove dev arg of dsa_register_switch
The current dsa_register_switch function takes a useless struct device
pointer argument, which always equals ds->dev.
Drivers either call it with ds->dev, or with the same device pointer
passed to dsa_switch_alloc, which ends up being assigned to ds->dev.
This patch removes the second argument of the dsa_register_switch and
_dsa_register_switch functions.

[PATCH net-next] net: dsa: support cross-chip ageing time
Now that the switchdev bridge ageing time attribute is propagated to all
switch chips of the fabric, each switch can check if the requested value
is valid and program itself, so that the whole fabric shares a common
ageing time setting.
This is especially needed for switch chips in between others, containing
no bridge port members but evidently used in the data path.
To achieve that, remove the condition which skips the other switches. We
also don't need to identify the target switch anymore, thus remove the
sw_index member of the dsa_notifier_ageing_time_info notifier structure.
On ZII Dev Rev B (with two 88E6352 and one 88E6185) and ZII Dev Rev C
(with two 88E6390X), we have the following hardware configuration:
# ip link add name br0 type bridge
# ip link set master br0 dev lan6
br0: port 1(lan6) entered blocking state
br0: port 1(lan6) entered disabled state
# echo 2000 > /sys/class/net/br0/bridge/ageing_time
Before this patch:
zii-rev-b# cat /sys/kernel/debug/mv88e6xxx/sw*/age_time
30

15000
zii-rev-c# cat /sys/kernel/debug/mv88e6xxx/sw*/age_time

[PATCH net-next 06/20] net: dsa: change scope of VLAN handlers
Change the scope of the switchdev VLAN object handlers from the DSA
slave device to the generic DSA port, so that the future port-wide API
can also be used for other port types, such as CPU and DSA links.

[PATCH net-next 07/20] net: dsa: change scope of VLAN filtering setter
Change the scope of the switchdev VLAN filtering attribute setter from
the DSA slave device to the generic DSA port, so that the future
port-wide API can also be used for other port types, such as CPU and DSA
links.

Add two new DSA_NOTIFIER_MDB_ADD and DSA_NOTIFIER_MDB_DEL events to
notify not only a single switch, but all switches of a the fabric when
an MDB entry is added or removed.
For the moment, keep the current behavior and ignore other switches.

[PATCH net-next 16/20] net: dsa: move notifier info to private header
The DSA notifier events and info structure definitions are not meant for
DSA drivers and users, but only used internally by the DSA core files.
Move them from the public net/dsa.h file to the private dsa_priv.h file.
Also use this opportunity to turn the events into an anonymous enum,
because we don't care about the values, and this will prevent future
conflicts when adding (and sorting) new events.

[PATCH net-next 17/20] net: dsa: add notifier for ageing time
This patch keeps the port-wide ageing time handling code in
dsa_port_ageing_time, pushes the requested ageing time value in a new
switch fabric notification, and moves the switch-wide ageing time
handling code in dsa_switch_ageing_time.
This has the effect that now not only the switch that the target port
belongs to can be programmed, but all switches composing the switch
fabric. For the moment, keep the current behavior and ignore other
switches.

[PATCH net-next 00/20] net: dsa: distribute switch events
DSA is by nature the support for a switch fabric, which can be composed of a single, or multiple interconnected Ethernet switch chips. The current DSA core behavior is to identify the slave port targeted by a request (e.g. adding a VLAN entry), and program the switch chip to which it belongs accordingly. This is problematic in a multi-chip environment, since all chips of a fabric must be aware of most configuration changes. Here are some concrete examples in a 3-chip environment: [CPU] (mdio) (eth0) | : : : _|_______ [__sw0__]--[__sw1__]--[__sw2__] | | || | || | | v v vv v vv v v p1 p2 p3 p4 p5 p6 p7 p8 p9 If you add a VLAN entry on p7, sw2 gets programmed, but frames won't reach the CPU interface in a VLAN filtered setup. sw0 and sw1 also need to be programmed. The same problem comes with MAC addresses (FDB, MDB), or ageing time changes for instance. This patch series uses the notification chain introduced for bridging, to notify not only bridge, but switchdev attributes and objects events to all switch chips of the fabric. An ugly debug message printing the ignored event and switch info in the code handling the switch VLAN events would give us: # bridge vlan add dev p7 vid 42 sw0: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (prepare phase) sw1: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (prepare phase) sw0: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (commit phase) sw1: ignoring DSA_NOTIFIER_VLAN_ADD for sw2 (commit phase) To achieve that, patches 1-8 change the scope of the bridge and switchdev callbacks from the DSA slave device to the generic DSA port, so that the port-wide API can be used later for switch ports not exposed to userspace, such as CPU and DSA links. Patches 9-15 move the DSA port specific functions in a new port.c file. Patches 16-20 introduce new events to notify the fabric about switchdev attributes and objects manipulation. This patch series only adds the plumbing to support a distributed configuration, but for the moment, each switch chip ignores events from other chips of the fabric, to keep the current behavior. The next patch series will add support for cross-chip configuration of bridge ageing time, VLAN and MAC address databases operations, etc. Vivien Didelot (20): net: dsa: change scope of STP state setter net: dsa: change scope of notifier call chain net: dsa: change scope of bridging code net: dsa: change scope of FDB handlers net: dsa: change scope of MDB handlers net: dsa: change scope of VLAN handlers net: dsa: change scope of VLAN filtering setter net: dsa: change scope of ageing time setter net: dsa: move port state setters net: dsa: move bridging routines net: dsa: move VLAN filtering setter net: dsa: move ageing time setter net: dsa: move FDB handlers net: dsa: move MDB handlers net: dsa: move VLAN handlers net: dsa: move notifier info to private header net: dsa: add notifier for ageing time net: dsa: add FDB notifier net: dsa: add MDB notifier net: dsa: add VLAN notifier include/net/dsa.h | 10 -- net/dsa/Makefile | 2 +- net/dsa/dsa_priv.h | 83 + net/dsa/port.c | 260 +++ net/dsa/slave.c| 354 + net/dsa/switch.c | 175 ++ 6 files changed, 547 insertions(+), 337 deletions(-) create mode 100644 net/dsa/port.c -- 2.13.0
[PATCH net-next 01/20] net: dsa: change scope of STP state setter
Instead of having multiple STP state helpers scoping a slave device
supporting both the DSA logic and the switchdev binding, provide a
single dsa_port_set_state helper scoping a DSA port, as well as its
dsa_port_set_state_now wrapper which skips the prepare phase.
This allows us to better separate the DSA logic from the slave device
handling.

an VLAN entry is added or removed.

Change the scope of the switchdev bridge ageing time attribute setter
from the DSA slave device to the generic DSA port, so that the future
port-wide API can also be used for other port types, such as CPU and DSA
links.
Also ds->ports is now a contiguous array of dsa_port structures, thus
their addresses cannot be NULL. Remove the useless check in
dsa_fastest_ageing_time.

But factorizing br_mdb_do still makes sense. I'll come up with something. Thanks, Vivien

OK good to know. That intention wasn't obvious. I can make __br_mdb_del
return void instead? What about the rest of the patchset if I do so?
Thanks,

[PATCH net-next 6/6] net: bridge: add br_mdb_do
Now that the two functions br_mdb_add and br_mdb_del are identical, keep

__br_mdb_del and notify the message type on success.
Factorize this in a new __br_mdb_do function which add or delete a
br_mdb_entry depending on the message type, then notify it.
Note that the dev argument is p->br->dev, so no need to pass it twice.

[PATCH net-next] net: dsa: store CPU port pointer in the tree
A dsa_switch_tree instance holds a dsa_switch pointer and a port index
to identify the switch port to which the CPU is attached.
Now that the DSA layer has a dsa_port structure to hold this data, use
it to point the switch CPU port.
This patch simply substitutes s/dst->cpu_switch/dst->cpu_dp->ds/ and
s/dst->cpu_port/dst->cpu_dp->index/.
