2022-09-20packetforge: add packetforge for generic flow to extrasTing Xu98-0/+4330
Add a new tool packetforge to extras. This tool is to support generic flow. Packetforge is a library to translate naming or json profile format flow pattern to the required input of generic flow, i.e. spec and mask. Using python script flow_create.py, it can add and enable a new flow rule for an interface via flow VAPI, and can delete an existed flow rule as well. Command examples are shown below. Json profile examples can be found in ./parsegraph/samples. Naming format input: python flow_create.py --add -p "mac()/ipv4(src=1.1.1.1,dst=2.2.2.2)/udp()" -a "redirect-to-queue 3" -i 1 python flow_create.py --del -i 1 -I 0 Json profile format input: python flow_create.py -f "./flow_rule_examples/mac_ipv4.json" -i 1 With this command, flow rule can be added or deleted, and the flow entry can be listed with "show flow entry" command in VPP CLI. Packetforge is based on a parsegraph. The parsegraph can be built by users. A Spec can be found in ./parsegraph as guidance. More details about packetforge are in README file.

2022-09-20vcl: align the RST behaviour with kernelYacan Liu1-1/+13
When ESTABLISHED TCP connection is terminated by an RST packet, EPOLLHUP + EPOLLRDHUP would be updeliever by VCL. If not using VPP, app would receive EPOLLHUP + EPOLLERR + EPOLLIN(if requested) + EPOLLRDHUP(if requested). libevent will interpret the two cases as different EV combinations. Below is the code snippet for libevent v2.12: if (what & EPOLLERR) { ev = EV_READ | EV_WRITE; } else if ((what & EPOLLHUP) && !(what & EPOLLRDHUP)) { ev = EV_READ | EV_WRITE; } else { if (what & EPOLLIN) ev |= EV_READ; if (what & EPOLLOUT) ev |= EV_WRITE; if (what & EPOLLRDHUP) ev |= EV_CLOSED; } Type: fix Signed-off-by: Yacan Liu <liuyacan@corp.netease.com> Change-Id: Ice3d2861183b6ea499f66b727bbe175eeae5cb05
2022-09-20tests: run tests against a running VPPNaveen Joy4-12/+291
Usage: test/run.py -r -t {test_filter} Instead of starting a new instance of VPP, when the -r argument is provided, test is run against a running VPP instance. Optionally, one can also set the VPP socket directory using the -d argument. The default location for socket files is /var/run/user/${uid}/vpp and /var/run/vpp if VPP is started as root.

2022-09-15nat: fix nat44-ed port range with multiple workersVladislav Grishenko5-9/+207
The number of available dynamic ports is set to (0xffff - 1024) = 64511, which is not divisable by the pow2 number of workers - the only integer divisors are 31 and 2081. So, total dynamic port range of all workers will be less than it: 1 wrk: n = (port_per_thread = 64511/1)*1 = 64511 + 1025 = 65536 2 wrk: n = (port_per_thread = 64511/2)*2 = 64510 + 1025 = 65535 4 wrk: n = (port_per_thread = 64511/4)*4 = 64508 + 1025 = 65533 8 wrk: n = (port_per_thread = 64511/8)*8 = 64504 + 1025 = 65529 ... As seen, with multiple workers there are unused trailing ports for every nat pool address and that is the reason of out-of-bound index in the worker array on out2in path due (port - 1024) / port_per_thread math. This was fixed in 5c9f9968de63fa627b4a72b344df36cdc686d18a, so packets to unused ports will go to existing worker and dropped there. Per RFC 6335 https://www.rfc-editor.org/rfc/rfc6335#section-6: 6. Port Number Ranges o the System Ports, also known as the Well Known Ports, from 0-1023 (assigned by IANA) o the User Ports, also known as the Registered Ports, from 1024- 49151 (assigned by IANA) o the Dynamic Ports, also known as the Private or Ephemeral Ports, from 49152-65535 (never assigned) According that let's allocate dynamic ports from 1024 and have full port range with a wide range of the workers number - 64 integer divisors in total, including pow2 ones: 1 wrk: n = (port_per_thread = 64512/1)*1 = 64512 + 1024 = 65536 2 wrk: n = (port_per_thread = 64512/2)*2 = 64512 + 1024 = 65536 3 wrk: n = (port_per_thread = 64512/3)*3 = 64512 + 1024 = 65536 4 wrk: n = (port_per_thread = 64512/4)*4 = 64512 + 1024 = 65536 5 wrk: n = (port_per_thread = 64512/5)*5 = 64510 + 1024 = 65534 6 wrk: n = (port_per_thread = 64512/6)*6 = 64512 + 1024 = 65536 7 wrk: n = (port_per_thread = 64512/7)*7 = 64512 + 1024 = 65536 8 wrk: n = (port_per_thread = 64512/8)*8 = 64512 + 1024 = 65536 ... Modulo from 5c9f9968de63fa627b4a72b344df36cdc686d18a is still required when the numbers of workers is not the integer divisor of 64512.

2022-08-30memif: Process bad descriptors correctly in memif_process_descSteven Luong1-10/+35
When there is a bad descriptor, it may in the beginning, in the middle, or at the end of the batch if the batch has more than 3 descriptors. When processing a bad descriptor is encountered in the batch, we need to rollback n_buffers in memif_process_desc(), or the statement in the same function memif_add_copy_op (ptd, mb0 + src_off, bytes_to_copy, dst_off, n_buffers - 1); is wrong because it picks up the wrong buffer_vec_index of the bad descriptor while parsing a good descriptor immediately following the bad descriptor. n_buffers was incremented in the beginning of while (n_left) loop. The other problem is we should count the number of bad packets and reduce ptd->n_packets to get the correct number of packets for subsequent processing in device_input. The last fix is to check if n_buffers == 0 in device_input and skip doing any descriptor copy. This case can happen when all the descriptors are bad in the batch.
