Bing Zhao [Mon, 19 Apr 2021 17:51:30 +0000 (01:51 +0800)]
ethdev: introduce conntrack flow action and item

This commit introduces the conntrack action and item.

Usually the HW offloading is stateless. For some stateful offloading
like a TCP connection, HW module will help provide the ability of a
full offloading w/o SW participation after the connection was
established.

The basic usage is that in the first flow rule the application should
add the conntrack action and jump to the next flow table. In the
following flow rule(s) of the next table, the application should use
the conntrack item to match on the result.

A TCP connection has two directions traffic. To set a conntrack
action context correctly, the information of packets from both
directions are required.

The conntrack action should be created on one ethdev port and supply
the peer ethdev port as a parameter to the action. After context
created, it could only be used between these two ethdev ports
(dual-port mode) or a single port. The application should modify the
action via the API "rte_action_handle_update" only when before using
it to create a flow rule with conntrack for the opposite direction.
This will help the driver to recognize the direction of the flow to
be created, especially in the single-port mode, in which case the
traffic from both directions will go through the same ethdev port
if the application works as an "forwarding engine" but not an end
point. There is no need to call the update interface if the
subsequent flow rules have nothing to be changed.

Query will be supported via "rte_action_handle_query" interface,
about the current packets information and connection status. The
fields query capabilities depends on the HW.

For the packets received during the conntrack setup, it is suggested
to re-inject the packets in order to make sure the conntrack module
works correctly without missing any packet. Only the valid packets
should pass the conntrack, packets with invalid TCP information,
like out of window, or with invalid header, like malformed, should
not pass.

4. HW capabilities.
5. rte_flow limitation.
6. Flexibility.

First option: Add integrity flags to each of the items.
For example add checksum_ok to IPv4 item.

Pros:
1. No new rte_flow item.
2. Simple in the way that on each item the app can see
what checks are available.

Cons:
1. API breakage.
2. Increase number of flows, since app can't add global rule and must
   have dedicated flow for each of the flow combinations, for example
   matching on ICMP traffic or UDP/TCP  traffic with IPv4 / IPv6 will
   result in 5 flows.

Second option: dedicated item

Pros:
1. No API breakage, and there will be no for some time due to having
   extra space. (by using bits)
2. Just one flow to support the ICMP or UDP/TCP traffic with IPv4 /
   IPv6.
3. Simplicity application can just look at one place to see all possible
   checks.
4. Allow future support for more tests.

Cons:
1. New item, that holds number of fields from different items.

For starter the following bits are suggested:
1. packet_ok - means that all HW checks depending on packet layer have
   passed. This may mean that in some HW such flow should be split to
   number of flows or fail.
2. l2_ok - all check for layer 2 have passed.
3. l3_ok - all check for layer 3 have passed. If packet doesn't have
   L3 layer this check should fail.
4. l4_ok - all check for layer 4 have passed. If packet doesn't
   have L4 layer this check should fail.
5. l2_crc_ok - the layer 2 CRC is O.K.
6. ipv4_csum_ok - IPv4 checksum is O.K. It is possible that the
   IPv4 checksum will be O.K. but the l3_ok will be 0. It is not
   possible that checksum will be 0 and the l3_ok will be 1.
7. l4_csum_ok - layer 4 checksum is O.K.
8. l3_len_OK - check that the reported layer 3 length is smaller than the
   frame length.

Example of usage:
1. Check packets from all possible layers for integrity.
   flow create integrity spec packet_ok = 1 mask packet_ok = 1 .....

2. Check only packet with layer 4 (UDP / TCP)
   flow create integrity spec l3_ok = 1, l4_ok = 1 mask l3_ok = 1
   l4_ok = 1

3 years agoethdev: introduce indirect flow action
Bing Zhao [Mon, 19 Apr 2021 14:38:29 +0000 (22:38 +0800)]
ethdev: introduce indirect flow action

Right now, rte_flow_shared_action_* APIs are used for some shared
actions, like RSS, count. The shared action should be created before
using it inside a flow. These shared actions sometimes are not
really shared but just some indirect actions decoupled from a flow.

The new functions rte_flow_action_handle_* are added to replace
the current shared functions rte_flow_shared_action_*.

There are two types of flow actions:
1. the direct (normal) actions that could be created and stored
   within a flow rule. Such action is tied to its flow rule and
   cannot be reused.
2. the indirect action, in the past, named shared_action. It is
   created from a direct actioni, like count or rss, and then used
   in the flow rules with an object handle. The PMD will take care
   of the retrieve from indirect action to the direct action
   when it is referenced.

The indirect action is accessed (update / query) w/o any flow rule,
just via the action object handle. For example, when querying or
resetting a counter, it could be done out of any flow using this
counter, but only the handle of the counter action object is
required.
The indirect action object could be shared by different flows or
used by a single flow, depending on the direct action type and
the real-life requirements.
The handle of an indirect action object is opaque and defined in
each driver and possibly different per direct action type.

The old name "shared" is improper in a sense and should be replaced.

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*", the testpmd application code and command
line interfaces also need to be updated to do the adaption.
The testpmd application user guide is also updated. All the "shared
action" related parts are replaced with "indirect action" to have a
correct explanation.

The parameter of "update" interface is also changed. A general
pointer will replace the rte_flow_action struct pointer due to the
facts:
1. Some action may not support fields updating. In the example of a
   counter, the only "update" supported should be the reset. So
   passing a rte_flow_action struct pointer is meaningless and
   there is even no such corresponding action struct. What's more,
   if more than one operations should be supported, for some other
   action, such pointer parameter may not meet the need.
2. Some action may need conditional or partial update, the current
   parameter will not provide the ability to indicate which part(s)
   to update.
   For different types of indirect action objects, the pointer could
   either be the same of rte_flow_action* struct - in order not to
   break the current driver implementation, or some wrapper
   structures with bits as masks to indicate which part to be
   updated, depending on real needs of the corresponding direct
   action. For different direct actions, the structures of indirect
   action objects updating will be different.

All the underlayer PMD callbacks will be moved to these new APIs.

The RTE_FLOW_ACTION_TYPE_SHARED is kept for now in order not to
break the ABI. All the implementations are changed by using
RTE_FLOW_ACTION_TYPE_INDIRECT.

Since the APIs are changed from "rte_flow_shared_action*" to the new
"rte_flow_action_handle*" and the "update" interface's 3rd input
parameter is changed to generic pointer, the mlx5 PMD that uses these
APIs needs to do the adaption to the new APIs as well.

2. From meson 0.49 onwards we have the "continue" keyword available to

remove blocks in the build configuration file which were conditional on the
"build" variable being true. Instead we can use "continue" to abort
processing at the point where the "build" value becomes false.

Elad Nachman [Mon, 29 Mar 2021 14:36:55 +0000 (15:36 +0100)]
kni: fix kernel deadlock with bifurcated device

KNI runs userspace callback with rtnl lock held, this is not working
fine with some devices that needs to interact with kernel interface in
the callback, like Mellanox devices.

The solution is releasing the rtnl lock before calling the userspace
callback. But it requires two consideration:

1. The rtnl lock needs to released before 'kni->sync_lock', otherwise it
   causes deadlock with multiple KNI devices, please check below the A.
   for the details of the deadlock condition.

2. When rtnl lock is released for interface down event, it cause a
   regression and deadlock, so can't release the rtnl lock for interface
   down event, please check below B. for the details.

As a solution, interface down event is handled asynchronously and for
all other events rtnl lock is released before processing the callback.

A. KNI sync lock is being locked while rtnl is held.
If two threads are calling kni_net_process_request() ,
then the first one will take the sync lock, release rtnl lock then sleep.
The second thread will try to lock sync lock while holding rtnl.
The first thread will wake, and try to lock rtnl, resulting in a
deadlock.  The remedy is to release rtnl before locking the KNI sync
lock.
Since in between nothing is accessing Linux network-wise, no rtnl
locking is needed.

B. There is a race condition in __dev_close_many() processing the
close_list while the application terminates.
It looks like if two KNI interfaces are terminating,
and one releases the rtnl lock, the other takes it,
updating the close_list in an unstable state,
causing the close_list to become a circular linked list,
hence list_for_each_entry() will endlessly loop inside
__dev_close_many() .

To summarize:
request != interface down : unlock rtnl, send request to user-space,
wait for response, send the response error code to caller in user-space.

request == interface down: send request to user-space, return immediately
with error code of 0 (success) to user-space.

The endianness specification of each action argument as part of the

file and auto-detected based on their destination. The DMA instruction
