2020-05-29Added initial support for NDP (IPv6)Xavier Simonart1-6/+64
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.

2020-05-29Added support for secondary process & virtual devicesXavier Simonart1-0/+10
A virtual device can be created adding the following option on the eal field within the eal options section: --vdev=net_ring0 This will cause a new (virtual) dpdk port to be created. Such a device can then be used in a primary process as other DPDK devices i.e. a [port x] section must be defined in the configuration file For a secondary process, there is no need to add --vdev, but, of course --proc-type=secondary (or --proc-type=auto) must be set within the eal field. There are two ways to use such a virtual device in a secondary process 1) Using the DPDK port number. Note however that the DPDK port number of virtual devices in the secondary process might not start from 0 and might hence have to be guessed e.g. if using 2 virtual devices in primary process (--vdev=net_ring0 --vdev=net_ring1) the port_id will be 0 and 1 in primary process and 2 & 3 in secondary process. 2) Using the port name, as defined in --vdev in the primary process. In this way, no [port] section must be defined, and the virtual port names are directly used within the "rx port" and "tx port" configuration e.g.: rx port=net_ring0 tx port=net_ring1 Limitations =========== There seems to be a PROX leak causing DPDK port id to increase when restarting the secondary process (causing the secondary process configuration through port id more difficult). As the primary process configures the port (including the number of rx and tx queues) based on its config file, the secondary process can't setup its own queues. Simple configurations (such as using gen or lat in primary, and swap in secondary) work as PROX allocates a RX queue even in gen mode and a TX queue even in lat mode. Better configuration/support for secondary process should be designed. The use of dpdk port names is only supported by PROX within "rx port" and "tx port". It is not supported by other configuration fields such as "tx ports from routing table". The use of dpdk port names in "rx port" and "tx port" is limited to only 1 port.

2020-05-29Added support for netlinkXavier Simonart1-1/+55
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).

2020-01-29Prepare for DPDK 19.08 supportXavier Simonart1-36/+36
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.

2019-10-09Add support for igmp and multicastXavier Simonart1-42/+162
Multicast can be enabled through configuration or through command line - Through configuration Add multicast=mcast_address (e.g. multicast=01:00:5e:01:02:03) in the port section - Through command line run enable multicast port_id mcast_address (e.g. enable multicast 1 01:00:5e:01:02:03) IGMP join message is sent unsollicited through command line: join igmp core_id task_id ip (e.g. join igmp 1 0 224.1.1.3) To enable swap answering IGMP Query (w/ IGMP Join) - Through configuration Add igmp ipv4=ip_address within the core/task section - Through command line join igmp core_id task_id ip (e.g. join igmp 1 0 224.1.1.3) (this will 1st initiate an unsollicated join, then answer any subsequent query) UDP/TCP packets received on a multicast address (224.0.0.0 => 239.255.255.255) are discarded To stop sending responses to IGMP query: leave igmp core_id task_id Change-Id: I3808ccabf3b38b5a1e10e1b044db63aa05bcd7b5 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-05-25Increase default mbuf size and code simplification/cleanupXavier Simonart1-4/+2
mbuf size was setup to achieve the best performance i.e. using the smallest mbuf and not segmenting packets. However this resulted in complex code, much dependent of the way the pmd are working e.g. a change(fix) in recent dpdk i40e implementation caused a 1782 (=1518+8+256) bytes mbuf to be too small to hold a 1518 bytes packets. Hence this change simplifies the mbuf size selection at the price of a potential decreases in performance - as more memory is now used. Except if jumbo frames are used, the mbuf size will now be the same for all modes. The packets will not be segmented except if jumbo frames are enabled. If jumbo frames are enabled, packets are by default segmented, except if the mbuf size is configured big enough in the config file.

2018-01-04Add config option to use port mac as src mac in l2fwd and swapXavier Simonart1-15/+21
L2fwd and swap has many options to set src mac. swap was supposed to support the ability to use port mac, but config file parsing was wrong. L2fwd was using port mac if a port was available and if src mac=packet or if there was no src mac in the config. Now l2fwd supports the following options - "src mac=xx:xx:xx:xx:xx:xx" => this mac address is used as src mac. - "src mac=packet" => the src mac is taken from the dst mac of the received packet. - "src mac=hw" => the src mac is taken from the mac address of the port, if there is a physical port. Error otherwise. - "src mac=no" => src mac kept untouched - No "src mac" => same as "src mac=hw" if there is a physical port and same as "src mac=packet" otherwise. Default is (no "src mac") hence the mac is taken from the tx port if there is one tx port and from the packet otherwise. swap support is similar, except that it does not support "src mac=no".
