Configure w/ --enable-dlmalloc, see .../build-data/platforms/vpp.mk src/vppinfra/dlmalloc.[ch] are slightly modified versions of the well-known Doug Lea malloc.

2018-07-15VPP-1341: fix loopback interface graph arcsDave Barach4-66/+175
Remove broken special case from l2_input.c:set_int_l2_mode(), which turns out to confuse the graph dispatch engine. The loopback TX function needs to push packets to either ethernet-input or to l2-input, based on bridge / BVI configuration. Rather than overloading a single graph arc - and making vain attempts to reconfigure it - create both arcs and use the correct one. Rewrote the loopback tx function as an idosyncratic multi-arch quad/single loop fn. Change-Id: I15b56ce641d90a11e7b3c7d23859f40e168dd7b2 Signed-off-by: Dave Barach <dave@barachs.net>
2018-07-14Improve IP4 ARP and IP6 ND Events Notificationv18.10-rc0John Lo2-11/+32
For L2 ARP termination, use both brodcast ARP request and reply packets to provide MAC/IP binding events. For IP4/IP6 neighbor adress resolution, send resolution events if there is an address resolution attemp with a static neighbor entry where both IP and MAC matches. This allow probe of an IP neighbor with a static entry to confirm it is responding with a reply matching that of the static entry.

Freeing the prefix and address vectors after signalling them from dhcpv6_client_node_fn to either the pd or iana report processes is absolutely wrong. The code has appeared to work by luck. This took three full days' worth of expert effort to root cause - in the context of an unrelated patch - and about one minute to fix.

2018-07-08Fix IPsec intf tx node setup at intf creationMatthew Smith1-2/+2
When using a DPDK cryptodev with IPsec, sending outbound packets results in a crash on division by zero if using an algorithm not supported by the OpenSSL ESP nodes. This includes AES-GCM and MD5. At IPsec intf creation time, the next node at slot IPSEC_OUTPUT_NEXT_ESP_ENCRYPT for ipsec_if_tx_node_fn is set to the node named esp-encrypt. This is the OpenSSL ESP encrypt function. If DPDK cryptodevs are configured, dpdk-esp-encrypt is the correct next node. Change to setting the next node according to the value in ipsec_main.esp_encrypt_node_index. That value is set to esp-encrypt by default. If DPDK cryptodevs are configured it gets set to dpdk-esp-encrypt.

and a new ip4-options node, inserted between ip4-input and ip4-punt, that checks for IP-router-alert option + IGMP combination and sends the packet to the ip4-local. This is required because some IGMP packets are sent to the group address and not the all-routers address. All IGMP packets are sent with the router alert option.

2018-06-27gcc8 and Wstringop-truncationMarco Varlese1-2/+2
gcc8 introduced a new warning (Wstringop-truncation) which in our case is being treated as error. Disabling the warning globally might introduce bugs related to string truncation which are not desired by the developer (e.g. bug). Instead, this patch disables the warning only for those occurences which have been verified to be non-bugs but the desired behaviour as per developer will.
