2020-05-29Added initial support for NDP (IPv6)Xavier Simonart1-3/+8
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 IMIX through config and command lineXavier Simonart1-0/+2
In Prox configuration IMIX can be specified using the following syntax: imix=pkt_size,pkt_size... Up to 127 different pkt sizes can be specified. Through command line, the following syntax can be used imix core_id task_id pkt_size,pkt_size... Up to 127 packet sizes can be specified. When IMIX is enabled, PROX will loop through the list of packet sizes. PROX supports two different submodes to handle pcap files. In the 1st submode (default, no submode specified), timestamps from the pcap file are ignored. In this submode IMIX is supported as well and each packets in the pcap file will be generated with all IMIX sizes. In the second submode, called pcap in gen mode, packets are generated at the timestamp specified in the pcap file. This submode does not support IMIX.

2020-05-29Added initial support for BGPXavier Simonart1-0/+1
Through this commit BGP messages are forwarded to tap device Netlink messages are enabled to receive route Updates. In addition, generating tasks can also specify a routing table which will be used when sending packets The routes initialized by the routing table can be changed through the reception of BGP messages Change-Id: I187ba9a921885cbc9b209aae5fb654309e3388b8 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2020-01-29Prepare for DPDK 19.08 supportXavier Simonart1-2/+3
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. Hence such a commit is rather easy to review and to reapply on other branches if necessary. sed -i 's/struct ether_hdr/prox_rte_ether_hdr/g' *.h sed -i 's/struct ether_hdr/prox_rte_ether_hdr/g' *.c sed -i 's/struct ether_addr/prox_rte_ether_addr/g' *.c sed -i 's/struct ether_addr/prox_rte_ether_addr/g' *.h sed -i 's/prox_rte_ether_addr_port/struct ether_addr_port/g' *.c sed -i 's/prox_rte_ether_addr_port/struct ether_addr_port/g' *.h sed -i 's/struct vlan_hdr/prox_rte_vlan_hdr/g' *.c sed -i 's/struct vlan_hdr/prox_rte_vlan_hdr/g' *.h sed -i 's/struct ipv4_hdr/prox_rte_ipv4_hdr/g' *.h sed -i 's/struct ipv4_hdr/prox_rte_ipv4_hdr/g' *.c sed -i 's/struct ipv6_hdr/prox_rte_ipv6_hdr/g' *.c sed -i 's/struct ipv6_hdr/prox_rte_ipv6_hdr/g' *.h sed -i 's/struct udp_hdr/prox_rte_udp_hdr/g' *.c sed -i 's/struct udp_hdr/prox_rte_udp_hdr/g' *.h sed -i 's/struct tcp_hdr/prox_rte_tcp_hdr/g' *.c sed -i 's/struct tcp_hdr/prox_rte_tcp_hdr/g' *.h sed -i 's/struct prox_rte_ether_addr_copy/ether_addr_copy/g' *.c sed -i 's/struct prox_rte_ether_addr_copy/ether_addr_copy/g' *.h sed -i 's/struct prox_rte_ether_addr_copy/prox_rte_ether_addr_copy/g' *.c sed -i 's/struct prox_rte_ether_addr_copy/ether_addr_copy/g' *.h sed -i 's/prox_rte_ether_addr_copy/ether_addr_copy/g' *.h sed -i 's/prox_rte_ether_addr_copy/ether_addr_copy/g' *.c sed -i 's/ether_addr_copy/prox_rte_ether_addr_copy/g' *.c sed -i 's/ether_addr_copy/prox_rte_ether_addr_copy/g' *.h sed -i 's/prox_rte_ether_hdr_arp/struct ether_hdr_arp/g' *.h sed -i 's/prox_rte_ether_hdr_arp/struct ether_hdr_arp/g' *.c sed -i 's/struct vxlan_gpe_hdr/prox_rte_vxlan_gpe_hdr/g' *.h sed -i 's/struct vxlan_gpe_hdr/prox_rte_vxlan_gpe_hdr/g' *.c sed -i 's/eth_random_addr/prox_rte_eth_random_addr/g' *.c sed -i 's/eth_random_addr/prox_rte_eth_random_addr/g' *.h sed -i 's/ETHER_CRC_LEN/PROX_RTE_ETHER_CRC_LEN/g' *.c sed -i 's/ETHER_CRC_LEN/PROX_RTE_ETHER_CRC_LEN/g' *.h sed -i 's/ETHER_HDR_LEN/PROX_RTE_ETHER_HDR_LEN/g' *.c sed -i 's/ETHER_HDR_LEN/PROX_RTE_ETHER_HDR_LEN/g' *.h sed -i 's/ETHER_MAX_LEN/PROX_RTE_ETHER_MAX_LEN/g' *.c sed -i 's/ETHER_MAX_LEN/PROX_RTE_ETHER_MAX_LEN/g' *.h sed -i 's/ETHER_MIN_LEN/PROX_RTE_ETHER_MIN_LEN/g' *.c sed -i 's/ETHER_MIN_LEN/PROX_RTE_ETHER_MIN_LEN/g' *.h sed -i 's/TCP_SYN_FLAG/PROX_RTE_TCP_SYN_FLAG/g' *.c sed -i 's/TCP_RST_FLAG/PROX_RTE_TCP_RST_FLAG/g' *.c sed -i 's/TCP_FIN_FLAG/PROX_RTE_TCP_FIN_FLAG/g' *.c sed -i 's/TCP_ACK_FLAG/PROX_RTE_TCP_ACK_FLAG/g' *.c Change-Id: I4dfe8be68e618c94dcaae28754579fbeb571bb00 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2019-10-09Add support for igmp and multicastXavier Simonart1-0/+1
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>
2019-10-09Added support for DPDK 19.02 and 19.05Xavier Simonart1-4/+5
This includes supporting following API changes - RTE_VER_... now in rte_config.h instead of rte_version.h - <rte_ethdev.h> now seems required by <rte_eth_ctrl.h> - rte_sched_port_pkt_write takes extra argument - rte_sched_port_pkt_read_tree_path takes extra argument - enum rte_meter_color replaced by rte_color The extra argument, sched_port, is initialized based on qos_conf parameters. Modes such as qinq_encap4 uses sched_port when doing classification, but does not set qos_conf params. It inherits the sched_port from QoS Change-Id: If8312918241e7d482161a7538f53faac6c303e86 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2019-01-28Add support for configurable arp timers in L3 modeXavier Simonart1-0/+2
L3 mode supports two timers: - arp_update_time, defaulted to 1 second, which makes PROX to send arp request every second for active flows - arp_timeout, previously defaulted to 30 seconds, which makes PROX consider a MAC address as invalid if no arp_reply was received within those 30 seconds. Those timers values were hardcoded. They can now be configured through the configuration file (within the core section), using resp. "arp update time" and "arp timeout" keywords. Unit is milli seconds. The default becomes respectively 1 second and 2 weeks. Change-Id: I35e46e97df32ca44c2cdfae85a20ee015de5d6e1 Signed-off-by: Xavier Simonart <xavier.simonart@intel.com>
2018-05-25Increase default mbuf size and code simplification/cleanupXavier Simonart1-2/+0
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.

2018-04-26Support reading inline jumbo frame and dump themXavier Simonart1-1/+1
Add support for pkt_inline of jumbo frames. Dump the whole packet, and not a truncated packet. This might have a small impact on performance as the memory footprint is increased (by ~640K * number of tasks), resulting in potential higher DTLB misses.

2018-01-16Integrate irq mode into PROX (support display and command line)Xavier Simonart1-0/+1
irq mode can be used to show how a core is interrupted by other tasks. This mode does not handle packets. It only loops reading tsc. When the difference between two consecutive calls to rdtsc() is high then it means the core was interrupted. This task implementes the display, so that we can see a histogram of interrupts as well as the maximum, per core. Command line is also supported, through "show irq buckets" (too show the intervals of each buckets, in micrcoseconds), and the stats command line (showing the number of items in each buckets and the max)..

2017-11-15Add support for nop mode with l3 submodeXavier Simonart1-2/+6
The l3 submode was not supported in nop mode, as the nop mode uses some specific nop thread (and not generic). When L3 is specified, the nop mode must use the generic thread. In addition the l3 submode is implemented differently than other submodes. It is not supported through task_init structures (i.e. each task does not have to explicitely tell that it supports l3 submode). But this prevented to run both a nop with no submode and a nop with a l3 submode. Note that nop with l3 is usually not very useful - it handles arp (requests and response) but as nop, it does not swap IP addresses. So with a real switch, the packets transmitted will be received back... and l3 mode is usually mainly usefull when using a switch. However, there is at least one nop mode where l3 submode makes sense: when the nop does not transmit. In such cases, for instace used in conjunction with a gen l3, the nop receives all packets and forward the arp requests and responses to the master for handling.
