Re: [vpp-dev] VPP Socket API how to use from the application #socket-api #vpp #sock-api
Hi Ole, Thanks for your response, I have a question on other language, So we don't have any SOCKET API support for C/C++? The socket API support is possible with go/python right? //Ravi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] VPP Socket API how to use from the application #socket-api #vpp #sock-api
Hi Experts, I was trying to find out how to use socket-api instead of "VAPI" based API. Can you please provide how to use socket-api any pointer will be a great help. //Ravi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] VPP healthy or not, or VAPI connection is healthy or not #vapi #vpp #shm
Hi Experts, We are using several applications to communicate the VPP by using the VAPI. We are using Vapi_connect, Vapi_send, Vapi_recv calls, Sometimes I see one of the application can not able to communicate with VPP and it will give errors. At the same time other applications are running fine with VPP and VPP also running fine. So I have two questions, 1> How to determine the VAPI Connection is stable and its working? to take decision application reconnect/restart. 2> How to determine the VPP is in good state and its working? to take decision of vpp restart. Any pointer will be big help.. //Ravi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] VPP hangs after few hours of continuous VAPI Send/Recv #acl #abf #vapi
Hi Andrew, Thanks for prompt reply, Please find details below VAPI Configuration ==> I believe you are talking about this rv = vapi_connect (ctx, "checking", NULL, 512, 512, VAPI_MODE_BLOCKING, true); The VPP_IFADDR.cfg --> is for all interface information. The startup.conf for the VPP startup. I can try with Single worker thread.. but we need minimum 4 worker thread anyway. //Ravi vpp_ifaddr.cfg Description: Binary data startup.conf Description: Binary data -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

There is no transition on memif interfaces, and I am not running any traffic so no events on memif. Could you see if it is still reproducible if you disconnect the other components altogether ? (I am trying to see how reproducible it is in an isolated case, and if it is then hopefully it is something that could be made into a standalone harness that you might be able to share so i could try reproducing it locally. Yes, Its reproducible with standalone and I am using "vapi_connect" and "vapi_send"/"recv" calls for ACL creation and deletion.(I believe its SHM based) I will reproduce and provide gdb context. //Ravi. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] VPP hangs after few hours of continuous VAPI Send/Recv #acl #abf #vapi
Hi Experts, I am running several applications and calling some ACL/ABF API to add and delete rules in VPP, these rules are added/deleted from all the applications continuously. After 5 to 6 hours I see the VPP ACL/ABF API will return VAPI_OK but payload.retval is NONZero number, If we keep on add/delete after this error, the VPP crashes. If we just want to read version using VAPI it will give empty values and if we want to do "cli" using vppctl, the vppctl also hangs. only way to recover the VPP is "kill -9". Is anyone have any clue? if the VPP/VAPI gets hanged how can we make the VPP to normal state without "kill -9 " Any suggestion would be great help. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] acl ipv6 rule creation with VAPI. #acl #ipv6 #vapi

I got tired trying several ways to add the IPV6 ACL rules using API. I couldn't
successful.
The same thing working fine with IPv4 rule.
When I tried IPV6 rule, I am getting retval is -58, I am not able to figure out

*All the different ways to convert from ascii to IPV6 I tried, but in any case
the payload.retval is -58.*
*If I use inet_pton to ipv4, I am getting same error, but I am using inet_aton

Any other method to convert the ASCII to IPV6 address may help I am not sure...
Let us know if you guys find any problem in my code or... let us know the best
way to add IPV6 ACL rules from application.(we don't want to use vppctl)

Re: [vpp-dev] VAPI ACL addition. Not getting ACL index in response. #acl #acl_plugin #vapi
[Edited Message Follows]
Sorry for spamming, anyway, I found the problem.
I was sending wrong response structure causing the problem.
We supposed to use,
*vapi_msg_acl_add_replace_reply* *resp; but I was using
*vapi_payload_acl_add_replace_reply* *resp;
Its working fine.
Just incase some one wants to use above example, providing working one below.
printf ("--- Basic acl addition- reply test ---\n");
vapi_msg_acl_add_replace *acl= vapi_alloc_acl_add_replace(ctx, 1);
if(acl==NULL)
{
printf("ACL retuns NULL %d\n",__LINE__);
exit(1);
}

Re: [vpp-dev] VAPI ACL addition. Not getting ACL index in response. #acl #acl_plugin #vapi
Sorry for spamming, anyway, I found the problem.
I was sending wrong response structure causing the problem.
We supposed to use,
*vapi_msg_acl_add_replace_reply* *resp;
*vapi_payload_acl_add_replace_reply* *resp;
Its working fine.
Just incase some one wants to use above example, providing working one below.
printf ("--- Basic acl addition- reply test ---\n");

exit(1);

[vpp-dev] VAPI ACL addition. Not getting ACL index in response. #acl #acl_plugin #vapi
[Edited Message Follows]
Hi Experts,
We are trying to use VPP-API(VAPI) to create ACL rules.
We are using the VAPI in blocking mode to get response immediately.
We are getting the response back but the *ACL-INDEX is some other value*. Can
you please see the below code, if I am doing something wrong.
Any pointers are big help.

}
printf("So the reply receivied ACL Index %d Retval

I am expecting the *vapi_payload_acl_add_replace_reply *resp; should contain
the acl_index but not. Any help is truly appreciated.*

[vpp-dev] Delete ACL rules #acl_plugin #acl #abf
Hi Team, I am trying to find a way to delete the ACL rules. From the commands provided in acl-plugin, I coudn't find a way to delete the acls after addition. The only way to delete ACL rules are just restart VPP, I don't want to do that. How can we dynamically delete the rules? always the rules are getting piled up if we don't restart VPP. Can you please help me to provide a cli to delete the ACL rules. For example: set acl-plugin acl permit src 172.25.169.0/24 --> this is one ACL rule, if I want to delete which command should I use. //Ravi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] VLAN+IP based forwarding #acl, #abf #vlan #memif #forwarding #vpp
Hi Experts, We have our application reading packets through memif and does consume them. We are adding rules in the VPP to reach particualr memif based on dst IP. "ip route add 172.172.0.0/24 via 192.168.1.3 memif1/0" However we have a requirement, where the Destination NETWORK can overlap with other VLAN. So we need forward rules based on the "VLAN + MEMIF" For example If *VLAN is 301* and *DST IP is 172.173.0.0/24* it should reach to *memif1/0* If *VLAN is 302* and *DST IP is 172.173.0.0/24* it should reach to *memif2/0* If *VLAN is 302* and *DST IP is 172.174.0.0/24* it should reach to *memif1/0* If *VLAN is 301* and *DST IP is 172.174.0.0/24* it should reach to *memif2/0* We can not use *L2 xconnect* , which directly relays L2 packets to corresponding memif1/0, *We need DST and VLAN because our application handles multiple clients with same overlapping subnets with VLAN+IP based routing.* So we need *VLAN+DST IP based routing, any suggestion is a great help.* //Ravi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] VLAN based Forwarding to My application #vlan #memif #forwarding #acl
Hi Neale, Thanks for your suggestion and time. However I tried following things " set interface l2 xconnect memif1/0 memif2/0 set interface l2 xconnect memif2/0 memif1/0 " and forwarding to memif1/0 from some routing. the memif1/0 is getting received the packets. But memif2/0 is not getting received any thing? is xconnect doesn't work for across 2 memif interfaces? When I tried with the following commands, memif1/0 is receiving the packets set interface l2 xconnect BondEthernet0.1100 memif1/0 set interface l2 xconnect memif1/0 BondEthernet0.1100 But I need between 2 memifs? any help is appreciated. //Ravi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[Edited Message Follows] Hi Experts, We are trying to implement forwarding dst X.X.X.X/X subnet packets on interface Y to the memif1/0 To achieve that we used ACL and ABF policy rules.

[vpp-dev] BondedInterface and memif interface for raw packet #memif #BondedInterface #plugin
[Edited Message Follows]
Hi Experts,
We implemented a PLUGIN, this plugin reads packets from physical interface and
sends to memif.
We implemented this approach to get RAW packets to our application.
The memif other end is our application, it takes necessary action.
The packet flow would be
Devie-Input --> OUR Plugin --> Memif --> Our application.(Plugin filters the
packets and send to memif or Bond-input.)
or
Devie-Input --> OUR Plugin --> bond-input --> VPP processing.
Our plugin is working with only physical interface. Now we are trying to make
this work with Bonded Interface, its not working with bonded interface.
If we disable bond-input for that physical interface and only enable our plugin
it will work fine. But we needed BondedInterface support for LACP. So we can't
just avoid BondedInterface.
Our feature arc is
VNET_FEATURE_INIT (ipgw_ent, static) =
{
.arc_name = "device-input",
.node_name = "ravi_plugin",
.runs_before = VNET_FEATURES ("ethernet-input"),
};
I tried placing different arcs for my plugin, its not working. Can you please
suggest how can our plugin to make it work for logical interfaces.
Like if we want to make it work for BondedInterface.1100? which arc we should
choose, we need raw packets to our application.
Any mechanism which can provide RAW PACKET reading from VPP also works fine.
Any pointers are very big help.
//Ravi.

[vpp-dev] ACL IPV6 rule addition using the "set acl_plugin acl" command from "vppctl" #vppctl #acl #acl_plugin #ipv6
Hi Experts,
We were trying to create some ACL rules for IPv6 addresses,
*"set acl-plugin acl permit src 2001:5b0::1150::0/64 " in vppctl.
* "set acl-plugin acl permit ipv6 src 2001:5b0::1150::0/64 " in vppctl.
giving ACL index but when I check "show acl_plugin acl" its not giving any
information.
vpp# set acl-plugin acl ipv6 permit src 2001:5b0::1150::0/64
ACL index:1
vpp# show acl-plugin acl
acl-index 0 count 1 tag {cli}
0: ipv4 permit src 172.25.169.0/24 dst 0.0.0.0/0 proto 0 sport 0-65535 dport
0-65535
acl-index 1 count 0 tag {cli}
vpp#
We are using VPP 20.05 stable version. We couldn't able to set the ACL for IPv6.
We are not seeing any error message on the logs.
We could able to set ACL for IPv4 without any issue.
We tried same thing from vpp_api_test, still we couldn't able to set IPv6 rule.
Can you please provide some pointer for creating "acl rule for IPV6."
Thanks for your help.

.arc_name = "device-input",
*.node_name = "ipgw_ent",*
*.runs_before = VNET_FEATURES ("bond-input"),*

and the trace looks like below.

We needed bonded interface support for "LACP/Active-backup" creation.
However our main requirement is we need to get packets to our application as
"Raw" or "RawSocket" format, so that we can do filtering/forwarding depending
on our own logic.
That's why we used VPP--> ourplugin--> memif-->ourapplication,
Do you have any better approach, please suggest us. Or how to attach my plugin
to BondedInterface, anyone will solve our problem.

Now we have a requirement to create these filtering rules from Host Application. We have a problem to use VPPCOM/Binary API. DO we have any communication method from HOSTAPP to VPP Plugin? can you please provide any pointer which can help us to refer and develop? The Plugin currently registered with VPP and working fine. Can we make plugin to monitor on a file/event for these filtering rules which needed from HostAPP without impacting the normal fast path processing of plugin? Any pointers for which does "Control" and "Data plane" functionality in the same plugin without using VPPCOM/Binary API?

Re: [vpp-dev] vppcom and binary api #binapi #vapi #vppcom
Hi Florin/Team of experts, I have one more question, The basic requirement we have is We have to send some data from our application to our own plugin. While going through previous messages and documentation, we found we can use memif or quick sockets. Our question is, do we have any other VPP provided methods of communication between a Plugin and Application? if yes can you please provide a pointer. That may resolve our issue. //Ravi. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] vppcom and binary api #binapi #vapi #vppcom
Hi Florin,
Thanks for your response, however I have a question, If I want to use another
Binary API initialization do we need to do at our Application or in VPP code.
When I check VPP source code, the initialization always with "vpe-api"
vpe_api_init calls always vl_set_memory_region_name ("/vpe-api"); so wondering
do we have any other region present?
FYI: We are using 20.05 stable version.
Regards,
Ravi.

[vpp-dev] vppcom and binary api #binapi #vapi #vppcom
Hi Team, We have our application which uses VPPCOM sessions to read and write some packets. We have one more requirement that Application uses Vpp-binary api and provide some information to our own plugin. When we try calling this binary apis without VPPCOM session started or running, the VPP Binary APIs are working fine. When we try to call after VPPCOM session create then we are seeing our application crash in VPP library. So we want to understand, if we are using VPPCOM session, is vpp binary api not allowed to use? If that is true, do we have any other mechanism to call my plugin binary API? I don't want to use CLI because these APIs will get call in fast path. Please advice us. -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] Distributing VPPCOM TX sessions to different worker thread #vnet #vppcom #TxBuff
Thanks Florin for your response Please find my answers below 1> I opened the UDP sessions with vppcom_session_connect and these are always for TX and it will not receive any data. 2> No there is no sent traffic on these. I can try this part. 3> Actually the throughput as you know depends on different factors like cores and etc, we have 100G card but we have our own application has limit. So i cannot answer what maximum we can push. 4> Coming to the dropped the Input Queues are getting filled with traffic. *Connection State Rx-f Tx-f [1:0][U] 2001:5b0::1150:b883:31f:178:98f8:2035OPENED 0 7999863 [1:1][U] 2001:5b0::1150:b883:31f:178:98f8:5100OPENED 0 7999863 [1:2][U] 2001:5b0::1150:b883:31f:178:98f8:1160OPENED 0 7999863 [1:3][U] 2001:5b0::1150:b883:31f:178:98f8:3442OPENED 0 7999863 [1:4][U] 2001:5b0::1150:b883:31f:178:98f8:1220OPENED 0 7999863 [1:5][U] 2001:5b0::1150:b883:31f:178:98f8:3303OPENED 0 7999863 [1:6][U] 2001:5b0::1150:b883:31f:178:98f8:5397OPENED 0 0 [1:7][U] 2001:5b0::1150:b883:31f:178:98f8:2545OPENED 0 0 [1:8][U] 2001:5b0::1150:b883:31f:178:98f8:4097OPENED 0 0 [1:9][U] 2001:5b0::1150:b883:31f:178:98f8:3618OPENED 0 0 [1:10][U] 2001:5b0::1150:b883:31f:178:98f8:141OPENED 0 0 [1:11][U] 2001:5b0::1150:b883:31f:178:98f8:465OPENED 0 0 Thread 1: active sessions 12* The Interface Counters doesn't have drops, RX FIFO and TX-FIFO rx-fifo-size 800 tx-fifo-size 800 Please let me know is there any other method to distribute these TX Flows or increase the throughput. //Ravi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] Distributing VPPCOM TX sessions to different worker thread #vnet #vppcom #TxBuff
Hi Team, We are planning to use VPP for throughput enhancement with our Applications. However I found a bottleneck in TX side. So our application is placed like this VPP RX Interface--> VPP Memif --> Our Application --> VPPCOM UDP session --> VPP TX Interface. The RX part we are not seeing issue and we could able to reach expected throughput. However with TX we are suffering to push same amount of traffic out. After further investigation I found, the TX sessions are only on Worker 1, These are not getting distributed among other threads, vpp# show sess verbose Connection State Rx-f Tx-f [0:0][U] 2001:5b0::1150:b883:31f:178:98f8:7428LISTEN 0 0 [0:1][U] 2001:5b0::1150:b883:31f:678:98f8:7428LISTEN 0 0 [0:2][U] 2001:5b0::1150:b883:31f:378:98f8:7428LISTEN 0 0 [0:3][U] 2001:5b0::1150:b883:31f:278:98f8:7428LISTEN 0 0 [0:4][U] 2001:5b0::1150:b883:31f:578:98f8:7428LISTEN 0 0 [0:5][U] 2001:5b0::1150:b883:31f:478:98f8:7428LISTEN 0 0 Thread 0: active sessions 6 Connection State Rx-f Tx-f *[1:0][U] 2001:5b0::1150:b883:31f:178:98f8:2194OPENED 0 0* *[1:1][U] 2001:5b0::1150:b883:31f:178:98f8:2753OPENED 0 0* *[1:2][U] 2001:5b0::1150:b883:31f:178:98f8:5163OPENED 0 0* *[1:3][U] 2001:5b0::1150:b883:31f:178:98f8:6022OPENED 0 0* *[1:4][U] 2001:5b0::1150:b883:31f:178:98f8:1272OPENED 0 0* *[1:5][U] 2001:5b0::1150:b883:31f:178:98f8:1222OPENED 0 0* *[1:6][U] 2001:5b0::1150:b883:31f:178:98f8:3080OPENED 0 0* *[1:7][U] 2001:5b0::1150:b883:31f:178:98f8:8598OPENED 0 0* *[1:8][U] 2001:5b0::1150:b883:31f:178:98f8:2764OPENED 0 0* *[1:9][U] 2001:5b0::1150:b883:31f:178:98f8:1567OPENED 0 0* *[1:10][U] 2001:5b0::1150:b883:31f:178:98f8:243OPENED 0 0* *[1:11][U] 2001:5b0::1150:b883:31f:178:98f8:458OPENED 0 0* Thread 1: active sessions 12 Thread 2: no sessions Connection State Rx-f Tx-f [3:0][U] 2001:5b0::1150:b883:31f:178:98f8:7428OPENED 0 0 [3:1][U] 2001:5b0::1150:b883:31f:678:98f8:7428OPENED 0 0 Thread 3: active sessions 2 Connection State Rx-f Tx-f [4:0][U] 2001:5b0::1150:b883:31f:278:98f8:7428OPENED 0 0 [4:1][U] 2001:5b0::1150:b883:31f:578:98f8:7428OPENED 0 0 Thread 4: active sessions 2 Thread 5: no sessions Connection State Rx-f Tx-f [6:0][U] 2001:5b0::1150:b883:31f:378:98f8:7428OPENED 0 0 [6:1][U] 2001:5b0::1150:b883:31f:478:98f8:7428OPENED 0 0 Thread 6: active sessions 2 That is creating Bottleneck, Please find our RX placement, vpp# show interface rx-placement Thread 1 (vpp_wk_0): node memif-input: memif15/0 queue 0 (polling) memif16/0 queue 0 (polling) Thread 2 (vpp_wk_1): node memif-input: memif2/0 queue 0 (polling) memif4/0 queue 0 (polling) Thread 3 (vpp_wk_2): node memif-input: memif3/0 queue 0 (polling) memif14/0 queue 0 (polling) node dpdk-input: HundredGigabitEthernet12/0/0 queue 2 (polling) Thread 4 (vpp_wk_3): node memif-input: memif1/0 queue 0 (polling) memif12/0 queue 0 (polling) node dpdk-input: HundredGigabitEthernet12/0/0 queue 3 (polling) Thread 5 (vpp_wk_4): node memif-input: memif11/0 queue 0 (polling) memif13/0 queue 0 (polling) node dpdk-input: HundredGigabitEthernet12/0/0 queue 0 (polling) Thread 6 (vpp_wk_5): node memif-input: memif5/0 queue 0 (polling) memif6/0 queue 0 (polling) node dpdk-input: HundredGigabitEthernet12/0/0 queue 1 (polling) vpp# We made sure the RX queues are on not on worker 1 and 0, there is slight improvement but not upto the mark, So our question is, 1> How can we distribute these TX sessions among different workers? 2> Or How can we attain maximum with one thread?

[vpp-dev] Can one memif have multiple sockets
Hi Team, I realized that memif and corresponding sockets are tightly coupled. Means for example memif1 --> /run/vpp/memif1.sock --> application. We can not have multiple sockets for memif1, is my understanding correct? memif1 --> /run/vpp/memif1.sock if its already mapped, then we can not create memif1-->/run/vpp/memif2.sock please let me know if my understanding wrong and we can create multiple sockets for single interface? //Ravi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[vpp-dev] Sub Interface/VLAN receiving packets directly from the Interface and multi thread approach
[Edited Message Follows] Hi Team, I have written a plugin attached to device_input and running before ethernet_input. I am receiving all the packets for that particular physical interface. Actually this is working as we expected and okay. Now I have a requirement to get packets only for a particular sub interface/VLAN interface. If I want to receive the packets(Layer2 level) from VLAN interface where should I attach my plugin? I know attaching at device_input we are getting VLAN packets also but we don't want to get all the packets to plugin, because the plugin with become bottleneck for whole my system. Next question I have is, Is it okay to implement multi thread approach in plugin, because my system must reach line speed? In multi thread approach, My plugin can spawn one thread for one interface(could be VLAN) its monitoring, Like that it will spawn several threads depending on the requirement. Do you think is it feasible approach? do you have any better approach to handle this situation? If we can't do parallel processing, I think we can not achieve line speed in my system, please advice me //Ravi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [vpp-dev] [discuss] sw_if_index in vent_buffer giving wrong IP address with ip_interface_address_get_address
Hi Dave, Sorry to bother you again, I am looking for the VLIB_RX and receiving interface only, I will explain the scenario below, I have a plugin, this plugin attached to the device_Input and runs before ethernet_input. In the plugin I am checking is this packet is ICMP, and is it dstinited to the received interface, if it destined to the received interface, we just fwd to normal VPP processing. As I told in my original email, the same packet shows two different addresses, even the index is the same for both cases and same index we can see in the "show inter" The Packet trace is also the same for the both versions. I tried with a physical interface, it also gave the same set interface ip add HundredGigabitEthernet12/0/0 192.168.198.2/24 set interface state HundredGigabitEthernet12/0/0 up set interface ip addr HundredGigabitEthernet12/0/0 2001:5b0::7cf0::98fc/64 set interface state HundredGigabitEthernetd8/0/0 up set interface ip addr HundredGigabitEthernetd8/0/0 192.168.200.2/24 I am getting the 192.168.200.2 for the sw_if_idx=1 only. Is there any other way, I can get an IP Address from the vlib_buffer(b)? Coming to VLIB_TX, We are going to fill the VLIB_TX from a hash map we are maintaining in our plugin depending on the packet type. Any thoughts will help us. //Ravi On Fri, Jun 19, 2020 at 2:57 PM Dave Barach (dbarach) wrote: > HundredGigabitEthernet12/0/0 (sw_if_index=1) has the ip address > 192.168.198.2.
