You might issue "git clean -fdx" to get rid of extraneous stuff and then redo "make build", or just check out a clean repo into a new directory. I have just checked out the fresh master on ubuntu 16.04.4 box, built it, and was able to run vat with all the plugins, using this command: sudo ./build-root/install-vpp_debug-native/vpp/bin/vpp_api_test plugin_path ./build-root/install-vpp_debug-native/vpp/lib64/vpp_api_test_plugins/ This is from the topmost VPP repo directory of course. If you then can reproduce the failure again, the detailed steps might be helpful to try to devise a way to fix it... --a On 4/3/18, Shashi Kant Singh <sksi...@altiostar.com> wrote: > Hi Andrew > > I saw this link, similar to my problem: > > https://www.mail-archive.com/vpp-dev@lists.fd.io/msg02547.html > > > When I try to give plugin_path, I get this error (even with a fresh > build) > > root@vbbubng6-shashi-7 vpp]# > ./build-root/install-vpp_debug-native/vpp/bin/vpp_api_test > plugin_path > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/ > lib64/vpp_plugins > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/kubeproxy_plugin.so: > undefined symbol: unformat_ip46_address > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/acl_plugin.so: > undefined symbol: format_bihash_48_8 > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/libsixrd_plugin.so: > undefined symbol: format_dpo_proto > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/lb_plugin.so: > undefined symbol: unformat_ip46_address > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/ixge_plugin.so: > undefined symbol: format_vnet_buffer > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/gtpu_plugin.so: > undefined symbol: l2input_main > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/memif_plugin.so: > undefined symbol: unix_main > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/pppoe_plugin.so: > undefined symbol: ip6_input_node > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/l2e_plugin.so: > undefined symbol: format_vnet_sw_if_index_name > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/nat_plugin.so: > undefined symbol: ip4_lookup_node > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/dpdk_plugin.so: > undefined symbol: unformat_vnet_hw_interface > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/ioam_plugin.so: > undefined symbol: _vlib_init_function_flow_report_init > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/stn_plugin.so: > undefined symbol: unformat_ip46_address > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/ila_plugin.so: > undefined symbol: unformat_vnet_sw_interface > load_one_plugin:42: > /bng5/shashi-7/vpp4_debug/vpp/build-root/install-vpp_debug-native/vpp/lib64/vpp_plugins/fl

Hi Balaji,
I'm currently working on UPF implementation [1] based on VPP that can be used
for 5G and 4G PGW/SGW deployments. The corresponding project that implements
the CP part of a SGW and PGW for that can be found at [2].
The UPF part so far has basic support for the Sx{a,b,c} reference points. N3 is
mostly identical to that, so 5G should almost work.
PDRs, FARs and simple URRs are supported.
The PDR support is somewhat hackish as the required ACL support needs DPDK
ACLs. It would great to have an ACL API within VPP that offers similar
functionality as the DPDK API. Unfortunaltly, the VPP ACL plugins are not
exposing enough functionality to be usable for PDRs.
Regards
Andreas

This post is in context of VPP usage and its value in the advancement of
Telecom world which I have put below, Appreciate your feedback.
It is well known fact that the next big thing in telecommunication world is 5G,
which is aiming to provide 10Gbps data rate along with support for
Massive IoT devices and various Mobile Broadband services. Having said that the
Radio Technology and Front haul of 5G is in evolution that is driven by 3GPP
forum.
On the topics of Back-haul bandwidth/data switching and routing, 3GPP is silent
and left it open for innovation thoughts.
In this context, based on the experience that I have gained by working on
Telecommunication products as well as in VPP, I believe that VPP can play a
greater role in Telecom back-haul data routing and forwarding.
For example following nodes, user plane data handling can be made available
using VPP
a. 5GC UPF (5G Core Network - User Plane Function)
b. 5G gNB – Split – CU-U( Control Unit – User Plane)
c. 4G LTE SGW and PGW nodes.
d. eNbGW (eNodeB gateway)
In this front, I want to understand about any work being carried in these areas
already in VPP.
If the forum is further interested I shall be happy to discuss further more
details at technical front, based on that we can discuss further plans on
design, coding, deployment milestones of the same.

Re: [vpp-dev] Developing application on top of VPP
Thanks Ray I could see that at VPP, I could receive at line rate of 10G, process and send out the traffic (macswap) When I tried to use the test_server / test_client (vcl_test_client), I could not go beyond 3.5G rate in stream test mode. It is probably because of VCL sockets being used to send and receive SINGLE packets at the vcl_test_client . It does not do multiple packet processing like VPP does. How would I get near line of packet send /receive using VCL in my application ? I see recvmmsg kind of function in VCL but it is still not implemented using vpp library.

If your intention is to do something monolithic like a tightly integrated VNF application. A VNF with L2, L3, L4 and app as an integrated appliance. Then the plugin _might_ make the sense for you, however I suspect that VCL library might still be easier to maintain and integrate with in this instance However if you intend to use a vSwitch on the system or you anticipate that a vSwitch will be used in the system. You can integrate the L2, L3 and L4 with the (VPP) vSwitch and have your App sit on VCL. This ends up being simplier and more lightweight, but you need to know that VPP can be your vSwitch.

[vpp-dev] Developing application on top of VPP
Hi There is a need to port AI kind of application on top of VPP. This could > 20k lines of code with fair complexity. Would it make sense to put this as plugin in VPP or have an independent application and connect to VPP using VCL? Does it mean that AI app need to be broken down in 10 of nodes if plugin is the option? Performance required from AI app is like that of a typical data path. Regards Shashi

There's really not enough information to understand what you're trying to accomplish to know how to help. Assuming that you are using LD_PRELOAD to "link the vcom library to the application", the vcom api layer redirects calls based on the fd to either vppcom or libc. Also what version of the code are you running? You should be aware that VCL/LD_PRELOAD is still largely experimental and under development. There are many features of the posix socket interface which are missing or have stub implementations. Development of VCL to date has been entirely use-case driven.

There's really not enough information to understand what you're trying to accomplish to know how to help. Assuming that you are using LD_PRELOAD to "link the vcom library to the application", the vcom api layer redirects calls based on the fd to either vppcom or libc. Also what version of the code are you running? You should be aware that VCL/LD_PRELOAD is still largely experimental and under development. There are many features of the posix socket interface which are missing or have stub implementations. Development of VCL to date has been entirely use-case driven.

In both the direction when I send data at 1Gbps, pkt size 1024, I see packet drop happening during decoding. I see the following from the traces: Packet 6 00:01:57:914904: dpdk-input TenGigabitEtherneta/0/0 rx queue 0 buffer 0x153a6: current data 14, length 1064, free-list 0, clone-count 0, totlen-nifb 0, trace 0x5 l4-cksum-computed l4-cksum-correct l2-hdr-offset 0 l3-hdr-offset 14 PKT MBUF: port 0, nb_segs 1, pkt_len 1078 buf_len 2176, data_len 1078, ol_flags 0x180, data_off 128, phys_addr 0x3674ea00 packet_type 0x11 l2_len 0 l3_len 0 outer_l2_len 0 outer_l3_len 0 Packet Offload Flags PKT_RX_IP_CKSUM_GOOD (0x0080) IP cksum of RX pkt. is valid PKT_RX_L4_CKSUM_GOOD (0x0100) L4 cksum of RX pkt. is valid Packet Types RTE_PTYPE_L2_ETHER (0x0001) Ethernet packet RTE_PTYPE_L3_IPV4 (0x0010) IPv4 packet without extension headers IP4: 14:02:ec:70:ae:55 -> 14:02:ec:72:ee:dc IPSEC_ESP: 192.168.1.2 -> 192.168.1.1 tos 0x00, ttl 253, length 1064, checksum 0x3650 fragment id 0x 00:01:57:914915: ip4-input-no-checksum IPSEC_ESP: 192.168.1.2 -> 192.168.1.1 tos 0x00, ttl 253, length 1064, checksum 0x3650 fragment id 0x 00:01:57:914924: ipsec-input-ip4 esp: sa_id 20 spi 1000 seq 13544422 00:01:57:914925: dpdk-esp-decrypt cipher aes-cbc-128 auth sha1-96 ESP: spi 1000, seq 13544422 00:01:57:914928: dpdk-crypto-input status: auth failed 00:01:57:914944: error-drop ip4-input: valid ip4 packets In the same trace successful case is as below: acket 7 00:01:57:914904: dpdk-input TenGigabitEtherneta/0/0 rx queue 0 buffer 0x1b8af: current data 14, length 1064, free-list 0, clone-count 0, totlen-nifb 0, trace 0x6 l4-cksum-computed l4-cksum-correct l2-hdr-offset 0 l3-hdr-offset 14 PKT MBUF: port 0, nb_segs 1, pkt_len 1078 buf_len 2176, data_len 1078, ol_flags 0x180, data_off 128, phys_addr 0x364e2c40 packet_type 0x11 l2_len 0 l3_len 0 outer_l2_len 0 outer_l3_len 0 Packet Offload Flags PKT_RX_IP_CKSUM_GOOD (0x0080) IP cksum of RX pkt. is valid PKT_RX_L4_CKSUM_GOOD (0x0100) L4 cksum of RX pkt. is valid Packet Types RTE_PTYPE_L2_ETHER (0x0001) Ethernet packet RTE_PTYPE_L3_IPV4 (0x0010) IPv4 packet without extension headers IP4: 14:02:ec:70:ae:55 -> 14:02:ec:72:ee:dc IPSEC_ESP: 192.168.1.2 -> 192.168.1.1 tos 0x00, ttl 253, length 1064, checksum 0x3650 fragment id 0x 00:01:57:914915: ip4-input-no-checksum IPSEC_ESP: 192.168.1.2 -> 192.168.1.1 tos 0x00, ttl 253, length 1064, checksum 0x3650 fragment id 0x 00:01:57:914924: ipsec-input-ip4 esp: sa_id 20 spi 1000 seq 13544423 00:01:57:914925: dpdk-esp-decrypt cipher aes-cbc-128 auth sha1-96 ESP: spi 1000, seq 13544423 00:01:57:914928: dpdk-crypto-input status: success 00:01:57:914945: dpdk-esp-decrypt-post cipher aes-cbc-128 auth sha1-96 TCP: 192.168.100.3 -> 192.168.100.2 tos 0x00, ttl 3, length 1006, checksum 0x04a7 fragment id 0x660d TCP: 1234 -> 5678 seq. 0x12345678 ack 0x12345690 flags 0x10 ACK, tcp header: 20 bytes window 8192, checksum 0xd8e8 00:01:57:914945: ip4-input-no-checksum TCP: 192.168.100.3 -> 192.168.100.2 tos 0x00, ttl 3, length 1006, checksum 0x04a7 fragment id 0x660d TCP: 1234 -> 5678 seq. 0x12345678 ack 0x12345690 flags 0x10 ACK, tcp header: 20 bytes window 8192, checksum 0xd8e8 00:01:57:914953: ip4-lookup fib 0 dpo-idx 1 flow hash: 0x TCP: 192.168.100.3 -> 192.168.100.2 tos 0x00, ttl 3, length 1006, checksum 0x04a7 fragment id 0x660d TCP: 1234 -> 5678 seq. 0x12345678 ack 0x12345690 flags 0x10 ACK, tcp header: 20 bytes window 8192, checksum 0xd8e8 00:01:57:914953: ip4-rewrite tx_sw_if_index 2 dpo-idx 1 : ipv4 via 192.168.100.2 TenGigabitEthernetc/0/0: 1402ec70ae6c1402ec70ae540800 flow hash: 0x : 1402ec70ae6c1402ec70ae540800450003ee660d020605a7c0a86403c0a8 0020: 640204d2162e123456781234569050102000d8e87778797a3031 00:01:57:914953: TenGigabitEthernetc/0/0-output TenGigabitEthernetc/0/0 IP4: 14:02:ec:70:ae:54 -> 14:02:ec:70:ae:6c TCP: 192.168.100.3 -> 192.168.100.2 tos 0x00, ttl 2, length 1006, checksum 0x05a7 fragment id 0x660d TCP: 1234 -> 5678 seq. 0x12345678 ack 0x12345690 flags 0x10 ACK, tcp header: 20 bytes window 8192, checksum 0xd8e8 00:01:57:914953: TenGigabitEthernetc/0/0-tx TenGigabitEthernetc/0/0 tx queue 2 buffer 0x1b8af: current data 44, length 1020, free-list 0, clone-count 0, totlen-nifb 0, trace 0x6
