This RFC series of patches attempt to extend the flow director filter to
add support for Chelsio T5 hardware filtering capabilities.
Chelsio T5 supports carrying out filtering in hardware which supports 3
actions to carry out on a packet which hit a filter viz.
1. Action Pass - Packets hitting a filter rule can be directed to a
particular RXQ.
2. Action Drop - Packets hitting a filter rule are dropped in h/w.
3. Action Switch - Packets hitting a filter rule can be switched in h/w
from one port to another, without involvement of host. Also, the
action Switch also supports rewrite of src-mac/dst-mac headers as
well as rewrite of vlan headers. It also supports rewrite of IP
headers and thereby, supports NAT (Network Address Translation)
in h/w.
Also, each filter rule can optionally support specifying a mask value
i.e. it's possible to create a filter rule for an entire subnet of IP
addresses or a range of tcp/udp ports, etc.
Patch 1 does the following:
- Adds an additional flow rte_eth_pkt_filter_flow which encapsulates
ingress ports, l2 payload, vlan and ntuples.
- Adds an additional mask for the flow to allow range of values to be
matched.
- Adds a new behavior 'switch'.
- Adds behavior arguments that can be passed when a particular behavior
is taken. For ex: in case of action 'switch', pass additional 4-tuple
to allow rewriting src/dst ip and port addresses to support NAT'ing.
Patch 2 shows testpmd command line example to support packet filter
flow.
Patch 3 announces ABI change for filtering support.
The patch series has been compile tested on all x86 gcc targets and the
current fdir filter supported drivers seem to return appropriate error
codes when this new flow type and the new action are not supported and
hence are not affected.
Posting this series mainly for discussion on API change. Once this is
agreeable then, I will post the cxgbe PMD changes to use the new API.

Add a new packet filter flow that allows filtering a packet based on
matching ingress port, ethertype, vlan, ip, and tcp/udp fields, i.e.
matching based on any or all fields at the same time.
Add the ability to provide masks for fields in flow to allow range of
values.
Add a new vlan flow containing inner and outer vlan to match. Add tos
and proto fields that can be matched for ipv4_flow.
Add a new behavior switch.
Add the ability to provide behavior arguments to allow insert/deletion
of matched fields in the flow. Useful when rewriting matched fields
with new values. Adds arguments for port, mac, vlan, and nat.
Ex: allows to provide new ip and port addresses to rewrite the fields
of packets matching a filter rule before NAT'ing.

Hi Rahul,
If ABI for fdir is going to be changed should we then take more general approach to accommodate other NICs as well? For example, for "rte_eth_ipv4_flow" you have "tos" and "proto" fields added, but "ttl" was left out of scope. I believe that "rte_eth_udpv6_flow" should be compatible with new IPv4 structure, so "flow label", "tc", "next header" and "hop limit" to be added as well as other NICs might have support for fdir rules for all these fields.
Regards,
Andrey

For example, for "rte_eth_ipv4_flow" you have "tos" and "proto" fields added, but "ttl" was left out of scope. I believe that "rte_eth_udpv6_flow" should be compatible with new IPv4 structure, so "flow label", "tc", "next header" and "hop limit" to be added as well as other NICs might have support for fdir rules for all these fields.

I agree.
I'll wait for some more review comments if there are any and then post a
v2 RFC series with above changes.

Hi Thomas,
I am preparing a v2 of this series where I will be accomodating some
more fields to be considered for filtering. However, if the overall
approach seems ok to everyone then, should I submit a separate patch
for this ABI change announcement ?

Apart from rte_eth_fdir_flow ABI change mentioned in above link, new
fields will be added to rte_eth_ipv4_flow and rte_eth_ipv6_flow,
which break their ABI.
Also, 4 new flow types will be added, which increases RTE_ETH_FLOW_MAX
from 18 to 22 and breaks the ABI.
Should I send a separate ABI change announce patch for each of them?
Thanks,
Rahul

This RFC series of patches attempt to extend the flow director filter to
add support for Chelsio T5 hardware filtering capabilities.
Chelsio T5 supports carrying out filtering in hardware which supports 3
actions to carry out on a packet which hit a filter viz.
1. Action Pass - Packets hitting a filter rule can be directed to a
particular RXQ.
2. Action Drop - Packets hitting a filter rule are dropped in h/w.
3. Action Switch - Packets hitting a filter rule can be switched in h/w
from one port to another, without involvement of host. Also, the
action Switch also supports rewrite of src-mac/dst-mac headers as
well as rewrite of vlan headers. It also supports rewrite of IP
headers and thereby, supports NAT (Network Address Translation)
in h/w.
Also, each filter rule can optionally support specifying a mask value
i.e. it's possible to create a filter rule for an entire subnet of IP
addresses or a range of tcp/udp ports, etc.
Patch 1 does the following:
- Adds an additional flow rte_eth_pkt_filter_flow which encapsulates
ingress ports, l2 payload, vlan and ntuples.
- Adds an additional mask for the flow to allow range of values to be
matched.
- Adds an ability to set both filters with masks (Maskfull) and
without masks (Maskless). Also allow prioritizing one of these
filter types over the other when a packet matches several types.
- Adds a new behavior 'switch'.
- Adds behavior arguments that can be passed when a particular behavior
is taken. For ex: in case of action 'switch', pass additional 4-tuple
to allow rewriting src/dst ip and port addresses to support NAT'ing.
Patch 2 shows testpmd command line example to support packet filter
flow.
The patch series has been compile tested on all x86 gcc targets and the
current fdir filter supported drivers seem to return appropriate error
codes when this new flow type and the new action are not supported and
hence are not affected.
Posting this series mainly for discussion on API change. Once this is
agreeable then, I will post the cxgbe PMD changes to use the new API.
---
v2:
1. Added ttl to rte_eth_ipv4_flow and tc, flow_label, next_header,
and hop_limit to rte_eth_ipv6_flow.
2. Added new field type to rte_eth_pkt_filter_flow to differentiate
between maskfull and maskless filter types.
3. Added new field prio to rte_eth_pkt_filter_flow to allow setting
priority over maskfull or maskless when packet matches multiple
filter types.
4. Added new behavior sub op RTE_FDIR_BEHAVIOR_SUB_OP_SWAP to allow
swapping fields in matched flows. For ex, useful when swapping mac
addresses in hardware before switching.
5. Updated the testpmd example to reflect the above new changes.
6. Dropped Patch 3 since the ABI announcement has already been merged.

Add a new packet filter flow that allows filtering a packet based on
matching ingress port, ethertype, vlan, ip, and tcp/udp fields, i.e.
matching based on any or all fields at the same time.
Add the ability to provide masks for fields in flow to allow range of
values. Allow selection of maskfull vs maskless filter types. Provide
mechanism to set priority to maskfull vs maskless filter types when
packet matches several filter types.
Add a new vlan flow containing inner and outer vlan to match. Add tos,
proto, and ttl fields that can be matched for ipv4 flow. Add tc,
flow_label, next_header, and hop_limit fields that can be matched for
ipv6 flow.
Add a new behavior switch.
Add the ability to provide behavior arguments to allow insert/deletion/
swapping of matched fields in the flow. Useful when rewriting matched
fields with new values. Adds arguments for port, mac, vlan, and nat.
Ex: allows to provide new ip and port addresses to rewrite the fields
of packets matching a filter rule before NAT'ing.

v2:
1. Added new field filter-type to allow specifying maskfull vs maskless
filter types.
2. Added new field filter-prio to allow specifying the priority between
maskfull and maskless filters i.e. if we have a maskfull and a
maskless filter both of which can match a single traffic pattern
then, which one takes the priority is determined by filter-prio.
3. Added new field flow-label to be matched for ipv6.

Any comments on this RFC series? If the overall approach is fine then,
I'll re-submit it as a PATCH series along with the CXGBE PMD driver
changes.

Why not use rte_eth_XX_flow directly but add a new one? Is it because of the mask? If so, how about to add a field in rte_eth_fdir_input like:
struct rte_eth_fdir_input {
uint16_t flow_type;
union rte_eth_fdir_flow flow;
/**< Flow fields to match, dependent on flow_type */
union rte_eth_fdir_flow flow_mask;
struct rte_eth_fdir_flow_ext flow_ext;
/**< Additional fields to match */
};

The packet filter flow is basically a superset containing Ethernet,
vlan, ipv4/ipv6 and tcp/udp flows whose fields can all be matched at
the same time, unlike in case of the current flow director which seems
to match only one of the flows at any given time. Additionally, it also
allows specifying masks. I separated the two to make this meaning
explicit. If this is not necessary, then I will merge them.

Yes, we can merge them. Would you like me to merge your patch here?

The current rte_eth_XX_flow only allow matching _one_ of the flows
because of the union. In contrast, rte_eth_pkt_filter_flow can match
several flows at the same time; i.e. it can match ethernet, vlan, ip,
and tcp/udp all at the same time. rte_eth_pkt_filter_flow is basically
a superset containing several flows that can be matched at the same
time.
In our Chelsio T5 hardware, it's possible to have several flows that can
be matched in a single rule. This is why I've created a superset that
can match several flows in the same rule.
Thanks,
Rahul

Thanks for clarification, now I understand. How about just define one to indicate using pkt_filter?
And move the IPV4_XX info to the structure rte_eth_pkt_filter?

The i40e driver implementation is done based on the change. If you'd like to merge,
maybe other patches in the patch set also need to be merged. Anyway, I think
maintainer can deal with it.

Thanks for clarification, it's clear. And it's great to have this feature.
Even it is a superset containing several flows, we still can use the
existing structs like
struct rte_eth_ipv4_flow {
struct rte_eth_l2_flow ether;
struct rte_eth_vlan_flow vlan;
uint32_t src_ip;
uint32_t dst_ip;
};
What do you think?
Thanks

Hi, Rahul
Just another thought, please consider about it:
Add a new flow type like
#define RTE_ETH_FLOW_IPV6_UDP_EX 17
+#define RTE_ETH_FLOW_RAW_PKT 18
Then add a new item in rte_eth_fdir_flow
union rte_eth_fdir_flow {
struct rte_eth_l2_flow l2_flow;
struct rte_eth_udpv4_flow udp4_flow;
struct rte_eth_tcpv4_flow tcp4_flow;
struct rte_eth_sctpv4_flow sctp4_flow;
struct rte_eth_ipv4_flow ip4_flow;
struct rte_eth_udpv6_flow udp6_flow;
struct rte_eth_tcpv6_flow tcp6_flow;
struct rte_eth_sctpv6_flow sctp6_flow;
struct rte_eth_ipv6_flow ipv6_flow;
struct rte_eth_mac_vlan_flow mac_vlan_flow;
struct rte_eth_tunnel_flow tunnel_flow;
+ uint8_t raw_pkt[80];
};
Then add mask item in rte_eth_fdir_input:
struct rte_eth_fdir_input {
uint16_t flow_type;
union rte_eth_fdir_flow flow;
+ union rte_eth_fdir_flow flow_mask;
/**< Flow fields to match, dependent on flow_type */
struct rte_eth_fdir_flow_ext flow_ext;
/**< Additional fields to match */
};
Then the filter can be added just in a format of raw packet, it looks generic, and even other NIC can use this too.
Thanks

This approach seems generic enough to allow any vendor specific data
to be passed in filter as well. However, 80 seems to be too low for
multiple flow types that can be combined in the same filter rule.
I think size of 256 seems reasonable.
Could the same thing be done for action arguments as well? Can we add
the same generic info to rte_eth_fdir_action too?
struct rte_eth_fdir_action {
uint16_t rx_queue;
enum rte_eth_fdir_behavior behavior;
enum rte_eth_fdir_status report_status;
uint8_t flex_off;
+ uint8_t behavior_arg[256];
};
This way, we can pass vendor specific action arguments too. What do
you think?
Also, now if we take this approach then, I am wondering, that all
vendors would need to document their own vendor-specific format of
taking filter match and filter action arguments, right?
And probably, even come up with their own example application showing
how to apply filters via dpdk on their card?
Thanks,
Rahul

Yes, 80 is just an example.

Yes, it also makes sense.

Yes, I guess it will be better to doc it or example it. Even currently, different kinds of NIC may need different configuration.
Or you can add description (how to configure) in your driver's comment log?
Not sure about the others' opinion?
Thanks

Ok. We will wait for a couple of days to get more opinions from others.
If the above generic approach is agreeable to everyone, then I will post
the patch series using this new approach.
Thanks,
