[dpdk-dev] [PATCH 7/7] net/i40e: enable cloud filter for GTP-C and GTP-U

[Beilei Xing]

GTP-C & GTP-U are not supported by cloud filter due
to limited resource of HW, this patch enables GTP-C
and GTP-U cloud filter by replacing inner_mac and
TUNNEL_KEY.
This configuration will be set when adding GTP-C or
GTP-U filter rules, and it will be invalid only by
NIC core reset.

Missing space after "flag", this line is also too long, you should add a
line break after the last comma.

Missing "." (pedantic mode enabled).

Wrong structure, should be rte_flow_item_gtp.

No need to capitalize everything, only the first one. Several missing spaces
betwen name and bit widths ("foo(42b)" => "foo (42b)").

There's also a typo on "Sequqnce".

These comments lack ending ".".

This field lack a comment, even if obvious, please add it for
consistency. You can use this opportunity to expand the acronym as well.

It's not a problem if you want to keep them separate, however note that you
could make the testpmd update part of this commit. The API change can be
considered useless without an implementation counterpart.

No need to repeat "GTP". You may also expand the TEID acronym.

Thanks for all the comments, will update them in V2.

[dpdk-dev] [PATCH v2 0/6] GPT-C and GTP-U enabling

[Beilei Xing]

This patch set enables RSS/FDIR/cloud filter for
GPT-C and GTP-U.
It depends on Kirill's patch:
http://www.dpdk.org/dev/patchwork/patch/28294/

v2 changes:
 - Enable RSS/FDIR/cloud filter dinamicly by checking profile
 - Add GTPC and GTPU items to distinguish rule for GTP-C or GTP-U
 - Rework FDIR/cloud filter enabling function

Beilei Xing (6):
  net/i40e: support RSS for GTP-C and GTP-U
  ethdev: add GTPC and GTPU items
  net/i40e: finish integration FDIR with generic flow API
  net/i40e: add FDIR support for GTP-C and GTP-U
  net/i40e: add cloud filter parsing function for GTP
  net/i40e: enable cloud filter for GTP-C and GTP-U

[dpdk-dev] [PATCH v2 6/6] net/i40e: enable cloud filter for GTP-C and GTP-U

[Beilei Xing]

GTP-C & GTP-U are not supported by cloud filter due
to limited resource of HW, this patch enables GTP-C
and GTP-U cloud filter by replacing inner_mac and
TUNNEL_KEY.
This configuration will be set when adding GTP-C or
GTP-U filter rules, and it will be invalid only by
NIC core reset.

Re: [dpdk-dev] [PATCH v2 2/6] ethdev: add GTPC and GTPU items

[Adrien Mazarguil]

Hi Beilei,

I assume this patch supersedes [1]?

[1] http://dpdk.org/ml/archives/dev/2017-August/073501.html

Thanks for merging testpmd and the API change as a single patch, I still
have a few comments, see below.

(please add "flow API" somewhere in the title by the way)

Won't there be a need to match nonspecific GTP traffic as well (both GTP-C
and GTP-U a once), since they use the same structure?

I'm not familiar with the protocol at all so I wonder if you should maybe
leave the GTP item in addition to those two.

You could refactor the TEID parameter since they use the same
structure. Might be useful if you add nonspecific GTP:

 ITEM_GTP,
 ITEM_GTP_TEID,
 ITEM_GTPC,
 ITEM_GTPU,

You can use a single section to describe all three items at once since they
map to a common structure:

 Item: ``GTP``, ``GTPC``, ``GTPU``:
 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Then elaborate a bit on the the differences between them.

Similarly:

The above field is not necessary since you're not initializing the entire

Thanks for all your comments.
Yes, http://dpdk.org/ml/archives/dev/2017-August/073501.html is superseded and did merging testpmd and API change.
I will update title in next version.

Agree, I will leave the GTP item in next version.

GTP-C and GTP-U use the same structure, the difference between them is UDP port, 2123 is for GTP-C, and 2152 is for GTP-U.
Add GTP-C and GTP -U item since I want to design a user-friendly CLI.

For example, if user wants to add such flow: assign GTP-U packets with TEID 0x123456 to queue 14. 
Then use can use following CLI:
flow create 0 ingress pattern eth / ipv4 / udp / gtpu teid is 0x123456 / end actions queue index 14 / end
instead of below CLI to distinguish GTP-C and GTP-U with UDP port:
flow create 0 ingress pattern eth / ipv4 / udp dst spec 2125 dst mask 0 / gtp teid is 0x123456 / end actions queue index 14 / end

And all your other comments will be addressed in next version, thanks.

I agree with you from a usability standpoint it's much nicer. I have one
question though, could one send GTP-C / GTP-U traffic using nondefault UDP
ports and expect hardware to match it without explicitly specifying a port
in the UDP item, that is, is there some property in GTP-C / GTP-U traffic
outside the UDP port that would theoretically allow a host (even a stateful
one) to tell them apart?

If it really depends on the UDP port only, not specifying one will use
hardware defaults regardless of the item (GTP / GTP-U / GTP-C). However if
like VXLAN, this default value can be modified outside of rte_flow, most
users will have to specify it regardless in order to get consistent results
across various vendors/adapters.

In any case I don't mind three items. GTP encompasses both GTP-U and GTP-C
(possibly two different UDP ports at once), while GTP-U and GTP-C match
exactly one. You only have to describe this properly in the documentation.

Thanks.

As far as I know, there's no other property in GTP-C / GTP-U traffic outside the UDP port to distinguish GTP-C and GTP-U. And I don't think the value can be modified by user just like VXLAN.

[dpdk-dev] [PATCH v3 0/8] GPT-C and GTP-U enabling

[Beilei Xing]

This patch set enables RSS/FDIR/cloud filter for GPT-C and GTP-U.
It depends on Kirill's patch:
http://dpdk.org/ml/archives/dev/2017-September/076035.html

v3 changes:
 - Rework implementation to support the new profile.
 - Add GTPC and GTPU tunnel type in software packet type parser.
 - Update ptype info when loading profile.
 - Fix bug of updating pctype info.


v2 changes:
 - Enable RSS/FDIR/cloud filter dinamicly by checking profile
 - Add GTPC and GTPU items to distinguish rule for GTP-C or GTP-U
 - Rework FDIR/cloud filter enabling function

[dpdk-dev] [PATCH v3 8/8] net/i40e: enable cloud filter for GTP-C and GTP-U

[Beilei Xing]

GTP-C & GTP-U are not supported by cloud filter due
to limited resource of HW, this patch enables GTP-C
and GTP-U cloud filter by replacing inner_mac and
TUNNEL_KEY.
This configuration will be set when adding GTP-C or
GTP-U filter rules, and it will be invalid only by
NIC core reset.

The index is I40E_PERSONALIZED_XXX right? Why not define it like
enum i40e_new_proto index? Or you can just use #define to define
personalized pctype instead of enum.

[dpdk-dev] [PATCH v4 0/8] GPT-C and GTP-U enabling

[Beilei Xing]

This patch set enables RSS/FDIR/cloud filter for GPT-C and GTP-U.
It depends on Kirill's patch:
http://dpdk.org/ml/archives/dev/2017-September/076035.html.
However, Kirill's patchset needs to be updated.

v4 changes:
 - Refine fdir related code.
 - Rework profile metadata parsing function.
 - Fix code style.

v3 changes:
 - Rework implementation to support the new profile.
 - Add GTPC and GTPU tunnel type in software packet type parser.
 - Update ptype info when loading profile.
 - Fix bug of updating pctype info.


v2 changes:
 - Enable RSS/FDIR/cloud filter dinamicly by checking profile
 - Add GTPC and GTPU items to distinguish rule for GTP-C or GTP-U
 - Rework FDIR/cloud filter enabling function

Beilei Xing (8):
  mbuf: support GTP in software packet type parser
  net/i40e: update ptype and pctype info
  net/i40e: support RSS for new pctype
  ethdev: add GTP items to support flow API
  net/i40e: finish integration FDIR with generic flow API
  net/i40e: add FDIR support for GTP-C and GTP-U
  net/i40e: add cloud filter parsing function for GTP
  net/i40e: enable cloud filter for GTP-C and GTP-U

[dpdk-dev] [PATCH v4 5/8] net/i40e: finish integration FDIR with generic flow API

[Beilei Xing]

rte_eth_fdir_* structures are still used in FDIR functions.
This patch adds i40e private FDIR related structures and
functions to finish integration FDIR with generic flow API.

[dpdk-dev] [PATCH v4 8/8] net/i40e: enable cloud filter for GTP-C and GTP-U

[Beilei Xing]

GTP-C & GTP-U are not supported by cloud filter due
to limited resource of HW, this patch enables GTP-C
and GTP-U cloud filter by replacing inner_mac and
TUNNEL_KEY.
This configuration will be set when adding GTP-C or
GTP-U filter rules, and it will be invalid only by
NIC core reset.

 - Fix code style.
 - Reword commit log.

v4 changes:
 - Refine fdir related code.
 - Rework profile metadata parsing function.
 - Fix code style.

v3 changes:
 - Rework implementation to support the new profile.
 - Add GTPC and GTPU tunnel type in software packet type parser.
 - Update ptype info when loading profile.
 - Fix bug of updating pctype info.


v2 changes:
 - Enable RSS/FDIR/cloud filter dinamicly by checking profile
 - Add GTPC and GTPU items to distinguish rule for GTP-C or GTP-U
 - Rework FDIR/cloud filter enabling function

[dpdk-dev] [PATCH v5 8/8] net/i40e: enable cloud filter for GTP-C and GTP-U

[Beilei Xing]

This patch sets TEID of GTP-C and GTP-U as filter type
by replacing existed filter types inner_mac and TUNNEL_KEY.
This configuration will be set when adding GTP-C or
GTP-U filter rules, and it will be invalid only by
NIC core reset.

In GTPv1-C, request messages are sent from any port to port 2123, and
in the response message the ports are reversed (in GTPv2-C, it's a
little more complicated). Is the intention to only match requests?
It's not clear.

Also, it should be mentioned that GTPv0 is not included (it uses port 3386)

The version field has 3 bits, not 2 (it was correct above). The
meaning of the 5 flags in this byte is different in GTPv2-C compared
to GTPv1-C. Is the intention to only support GTPv1? If so that should
be stated. If GTPv2 is supported, then the teid field below is not
present in a few cases and matching on it could cause some strange
behaviour.

Thanks for the correction, I will change version filed in next version.
And yes, we only support GTPv1 only, will clarify it.

[dpdk-dev] [PATCH v6 5/8] net/i40e: finish integration FDIR with generic flow API

[Beilei Xing]

rte_eth_fdir_* structures are still used in FDIR functions.
This patch adds i40e private FDIR related structures and
functions to finish integration FDIR with generic flow API.

[dpdk-dev] [PATCH v6 8/8] net/i40e: enable cloud filter for GTP-C and GTP-U

[Beilei Xing]

This patch sets TEID of GTP-C and GTP-U as filter type
by replacing existed filter types inner_mac and TUNNEL_KEY.
This configuration will be set when adding GTP-C or
GTP-U filter rules, and it will be invalid only by
NIC core reset.

This isn't a good description of GTP-C. GTP-C messages have a source
port of 2123, or a destination port of 2123.

In future, you might add support for GTPv2 (which is used since LTE).
Maybe this structure should have v1 in its name to avoid confusion?

0x30 isn't valid for GTP-C, the sequence number must be present in
GTP-C so it will be 0x32 or more. Is this byte actually matched
against by the device using the GTP pctypes?

Why use this value?

This will only match half of GTP-C messages. GTP-C messages have a UDP
port destination of 2123, or a UDP source port of 2123. To match all
GTP-C packets you need to look at both.

This is only valid if v_pt_rsv_flags is 0x30. GTP-U packets are
allowed to have a sequence number, which adds an extra 4 bytes to the
GTP header.

This is only valid if v_pt_rsv_flags is 0x30. GTP-U packets are
allowed to have a sequence number, which adds an extra 4 bytes to the
GTP header.

I considered it before. But I think we can modify it when we support GTPv2 in future, and keep concise 'GTP' currently:)  since I have described it matches v1 header.

You could rename v_pt_rsv_flags to version_flags to avoid some future
code changes to support GTPv2. There's still the issue that not all
GTPv2 messages have a TEID though.

We construct packets and send the packet to HW  to create flow director rule for GTP-C and
GTP-U. Actually I didn’t get error info with 0x30. And in my test, GTP-C packets can hit  GTP-C
pctype rule. Will try 0x32 later.

Just for constructing a GTP packet to create a fdir rule for one pctype, can use other values except 0xFF.

Yes. But the GTP profile for i40e didn't support response message.

For the GTP profile, there're 4 pctypes for GTP packets: GTPC, GTPU, GTPIPV4, and GTPIPV6.
HW parse which pctype the GTP packets belonge to.
We construct packet to create a fdir rule for one pctype, after that, all packets whose
pctype matches the rule's pctype will hit the rule.

Yes, actually I have no a good idea for the compatibility between GTPv1 and GTPv2 currently...
Maybe we can consider it in future.

That's not clear to a user of the rte_flow API

My point is that you can only assume the inner IP header starts at an
offset of sizeof(struct rte_flow_item_gtp) if v_pt_rsv_flags is
exactly 0x30. If you match only those packets then some GTP-U packets
will not be matched. That should be clear to a user of the rte_flow
API.

Rte_flow is a generic API, I think it should allow users to create rule for response message.
But i40e PMD does not the support response message, if user want to create a rule for i40e like below:
Flow create 0 ingress pattern eth / ipv4 / udp src is 2123 / gtpc / end / actions queue index 4 / end
It will fail. But maybe other PMD can support it.

No matter if  GTP-U packets has a sequence number, once message-type is 0xFF, the pctype
of the packet parsed by i40e HW will be GTPIPV4 or GTPIPV6. 
So If I create a flow rule for GTP-U packets with v_pt_rsv_flags 0x30 and message_type is 0xFF,
it means I create a rule for pctype GTPIPV4 or GTPIPV6.
Then GTP-U packets with v_pt_rsv_flags 0x32 can hit the rule because its pctype is also GTPIPV4
or GTPIPV6.
It's just i40e HW's behavior, doesn't mean it's effective for other NICs.
Hope I explain it clearly:)

Minor comments, how about:
	if (ret)
		PMD_DRV_LOG(ERR, "Failed to update mapping table.");

	rte_free(ptype_mapping);
	rte_free(ptype);
	return ret;

I checked with 0x32 for GTP-C, it works well. I will change to use 0x32 for GTP-C.
For GTP-U, for i40e, I will keep 0x30 for GTP-U since different GTP-U packet types
can match the same pctype.
Thanks for your all your comments.

[dpdk-dev] [PATCH v7 0/8] net/i40e: GPT-C and GTP-U enabling

[Beilei Xing]

This patch set enables RSS/FDIR/cloud filter for GPT-C and GTP-U.
It depends on Kirill's patch:
http://www.dpdk.org/dev/patchwork/patch/29325/

v7 changes:
 - Distinguish GTP-C request and response message in mbuf description.
 - Clarify GTP-C response message is not supported.
 - Version_type 0x30 is invalid for GTP-C, replace with 0x32.
 - Refine metadata parsing function.
 - Rework for checking fdir programming status.

v6 changes:
 - Reword description of GTP item and GTP structure, mainly support
   GTPv1, not include GTPv0 and GTPv2.

v5 changes:
 - Fix code style.
 - Reword commit log.

v4 changes:
 - Refine fdir related code.
 - Rework profile metadata parsing function.
 - Fix code style.

v3 changes:
 - Rework implementation to support the new profile.
 - Add GTPC and GTPU tunnel type in software packet type parser.
 - Update ptype info when loading profile.
 - Fix bug of updating pctype info.


v2 changes:
 - Enable RSS/FDIR/cloud filter dinamicly by checking profile
 - Add GTPC and GTPU items to distinguish rule for GTP-C or GTP-U
 - Rework FDIR/cloud filter enabling function

[dpdk-dev] [PATCH v7 8/8] net/i40e: enable cloud filter for GTP-C and GTP-U

[Beilei Xing]

This patch sets TEID of GTP-C and GTP-U as filter type
by replacing existed filter types inner_mac and TUNNEL_KEY.
This configuration will be set when adding GTP-C or
GTP-U filter rules, and it will be invalid only by
NIC core reset.

Although they have the same size, the header of these two protocols
obviously differs. My suggestion would be to go with a separate GTPv2
pattern item using its own dedicated structure instead.

The 1st four bytes are the same (flags in first byte have different
meanings, but the bits indicating the version are in the same
location). After that, different fields in each version are optional,
and the headers have variable size. A single structure could be used
if the first field is renamed to something like "version_flags", and
then check that the teid field in item->mask is not set if
((version_flags >> 5 == 2) && ((version_flags >> 4) & 1) == 1). If
there's going to be two structures, it would be good to put v1 and v2
in the names, in my opinion.

I don't know about GTP internals , but set passes from my scripts.

But there was a merge conflict (on top of master tree) on patch 3, it is
easy to resolve but I wonder if there is a dependency not mentioned? If
not can you please double check the patch.

Doesn't return here?
If it is impossible cus_pctype is NULL, the check is unnecessary.
Because you used the cus_ptype below.

I think the name GTP is OK for now. Due to v1 and v2 are different, why not rename them
when the v2 supporting are introduced?

[dpdk-dev] [PATCH v8 0/7] net/i40e: GPT-C and GTP-U enabling

[Beilei Xing]

 - Clarify GTP-C response message is not supported.
 - Version_type 0x30 is invalid for GTP-C, replace with 0x32.
 - Refine metadata parsing function.
 - Rework for checking fdir programming status.

v6 changes:
 - Reword description of GTP item and GTP structure, mainly support
   GTPv1, not include GTPv0 and GTPv2.

v5 changes:
 - Fix code style.
 - Reword commit log.

v4 changes:
 - Refine fdir related code.
 - Rework profile metadata parsing function.
 - Fix code style.

v3 changes:
 - Rework implementation to support the new profile.
 - Add GTPC and GTPU tunnel type in software packet type parser.
 - Update ptype info when loading profile.
 - Fix bug of updating pctype info.


v2 changes:
 - Enable RSS/FDIR/cloud filter dinamicly by checking profile
 - Add GTPC and GTPU items to distinguish rule for GTP-C or GTP-U
 - Rework FDIR/cloud filter enabling function

[dpdk-dev] [PATCH v8 7/7] net/i40e: enable cloud filter for GTP-C and GTP-U

[Beilei Xing]

This patch sets TEID of GTP-C and GTP-U as filter type
by replacing existed filter types inner_mac and TUNNEL_KEY.
This configuration will be set when adding GTP-C or
GTP-U filter rules, and it will be invalid only by
NIC core reset.

In any case I'd rather avoid renaming and modifying existing items and
structure contents once part of the API to avoid API/ABI breakage that
require deprecation notices, user applications updates and so on; rte_flow
has been created as a kind of append-only API for this reason (of course
there are exceptions, such as a bad design choice for the VLAN item I intend
to fix at some point).

I'm fine with the name "GTP" as defined now and documented as matching
GTPv1. We can add "GTPv2"-themed definitions later when some implementation
provides the ability to match this version. If you want to append the "v1"
suffix right now to be more explicit, I'm also fine with that. Your call.

Got your point, I'm also fine with the name now for GTPv1, and add "GTPv2" when
It is supported.
