2020-10-16Report failure when tap port is not mapped to real dpdk port.Xavier Simonart1-1/+1
When using "vdev=" in port section, a tap device and an additional dpdk port are created. In most cases, we still want to use a real DPDK device (i.e. bound to an interface such as virtio or a PF or a VF). PROX will now report by default an error when the used [port] is not a DPDK bound device. An additional parameter "virtual=yes" can be added in the port section in case one want to disable this error checking (e.g. specify additional parameter for the vdev device). This patch also fixes a potential endianess issue when configuring IP addresses. Change-Id: Iffdd9552308be3b77cfe2067630647acac2c01fe Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2020-09-21Added support for multiple vlans in ipv4 vdev modeXavier Simonart1-15/+34
When the following conditions are met: - ipv4 - vdev enabled Then multiple vlans are supported. Multiple vlans can be configured using the vlan_tag option within the port section of the config file. Multiple (different) local_ipv4/prefix must then also be configured within the same section. Note that for ipv6 multiple vlans are not supported (yet) Also, when vdev is not enabled, multiple vlans are also not (yet) supported.

2020-09-21Added support for reporting packet (mis)order.Xavier Simonart1-1/+1
The "Latency" screen has been updated with 3 columns: - mis-ordered Count the number of mis-ordered packets. - extent: Gives an indication of how mis-ordered the packets are. Receiving packet "x - 5" after receiving packet "x" will cause an extent of 5. - duplicate: Count number of duplicate packets. Following commands have been added for the impair mode: - proba no drop: replaces the former "probability" command. Percentage of forwarded packets. So 99.5 means 0.5% of packet drop. - proba delay Percentage of delayed packets for the impair mode. - proba duplicate Percentage of duplicate packets. Similar parameters are supported within the config files: - proba no drop - proba delay - proba duplicate Note: it is recommanded to use the signature when measuring packet misorder, as otherwise unexpected packet would cause miscounts.

2020-05-29Fix compilation issues on old DPDKXavier Simonart1-0/+1
Also fixed minor issues such as - prevent using vdev on DPDK <= 17.05 as not supported - potential segmentation fault after panic (if panic thrown early in prox initialization) Change-Id: I49a1962e95a4a44dddadd1fdd906e1b3b232465c Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2020-05-29VLAN support with vdev devices + few other changesXavier Simonart1-32/+47
- vdev devices now support VLAN. - kernel tap device can be configured with a netmask (/24 was always used in previous version). - when sending a (fake) packet to the kernel, this packet will now not be routed by the kernel (i.e. it will leave through the interface configured by PROX). This might change in the futture when PROX supports multiple VLANs per port. But today it prevents ARP being sent on management interfaces. - Log error in case kernel unable to send packet. - Added support for comments (';') in lua sections. - Prevent duplication of local_ipv4 - should now be configured in port section local_ipv4 in core section still supported Change-Id: I8f9a40fe6ad6f3013ff91b58b44627c7f34081e6 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2020-05-29Added initial support for NDP (IPv6)Xavier Simonart1-105/+485
Following messages are now handled by PROX - router_solicitation - neighbour_solicitation - router_advertisement - neighbour_advertisement The following parameters are supported (through the PROX config file) - sub mode=ndp This will enable handling of router and neighbour solicitation and advertisement. - local ipv6=xxxx:xxxx:xxxxx:xxxx:xxxx:xxxx:xxxx:xxxx This will configure the local IPv6 address of the port. This parameter is optional. If not specified, the local IPv6 will be calculated from the EUI. - global ipv6=xxxx:xxxx:xxxxx:xxxx:xxxx:xxxx:xxxx:xxxx This will configure the global IPv6 address of the port. This parameter is optional. If not specified, the global IPv6 will be calculated from the EUI and the router prefix received from the router. - ipv6 router=yes This will cause the core to behave as an IPv6 router i.e. it will generate Router Advertisement messages This is only useful in back to back cases, when no real IPv6 router is present in the setup. - router prefix=xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx The router prefix usedin the router advertisement The prefix will be used by the node to build an IPv6 global address in cases none were configured. "Unsollicited NA" parameter has been added within the core/task section. If set to yes (Unsollicited NA=yes), then an unsollicited neighbour Advertisement is sent at startup A same core/task cannot support both l3 and ndp mode. Those messages will be generated or handled when submode is set to "ndp": - neighbour sollicitation - neighbour advertisement - router sollicitation - router advertisement An example configuration is provided: config/ipv6.cfg in which port 0 / core 1 plays the role of the generator and port 1 / core 2 plays the role of the swap.

2020-05-29Fix mbuf leak and stop sending pseudo packetXavier Simonart1-2/+2
In addition to a mmbuf leak when receiving netlink routes packets this commit prevents sending the PROX pseudo packet i.e. the packet PROX sends to the kernel socket to have it generate an ARP request.

2020-05-29Added support for netlinkXavier Simonart1-56/+297
Through this commit ARP and ICMP messages are forwarded to the kernel when vdev tap devices are enabled, as well as PROX l3 mode. ICMP support has also been added to master (i.e. PROX L3 mode) and to swap (so when L3 submode is not enabled).

2020-05-29Add support for vdev tap devicesXavier Simonart1-4/+72
This commit adds support for the creation of tap devices. To create a tap device, and associate it with a DPDK port, add within the port section: vdev=<tap_name> local ipv4=<ip_assigned_to_port> <tap_name> will appear as a kernel network device, with an IP <ip_assigned_to_port> ARP packets received from the network on the DPDK interface will be forwarded to the kernel. 1st packet which needs to be generated to a new IP will cause an IP packet to be sent to the kernel (using socket sendto) forcing the kernel to send an ARP_REQUEST. In this commit, there is no notification from the kernel about ARP table changes. This is subject to further commits. Two config files, gen_tap.cfg and swap_tap.cfg have been created. They work one against each other. *** Note however that they do not work if running within the same host (with the port being connected back to back) *** This is due to the fact that the kernel would bypass the ports and use local interface...

2020-01-29Prepare for DPDK 19.08 supportXavier Simonart1-4/+4
This commit prepares PROX for supporting changes from DPDK 19.08 Mainly, the "sed" listed below were run. In addition, - some forward definition have been removed, - prox_compat.h has been updated - prox_compat.h has been included where necessary.

2019-01-30Fix memory leak in L3 submodeXavier Simonart1-0/+2
In L3 submodes, there were two memory leaks - when a L3 core was restarted, causing around 2MB leak and a potential issue after 256 start/stop - a potential mbuf leak when handling arp replies Those have been fixed Change-Id: I348478fa5967936297850432e93667e12b0adac4 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-12-13Fix issue in l3 mode when no arp reply was receivedXavier Simonart1-7/+26
When no arp reply was received in l3 mode, the requesting core continuously sends ARP requests every seconds (which is correct). But master core was keeping a list of all requests, while all those requests are the same, resulting in potential table overflow.
