2018-06-07DHCP Client DumpNeale Ranns4-60/+231
- use types on the DHCP API so that the same data is sent in comfing messages and in dumps - add the DHCP client dump API - update VOM to refelct API changes - rename VOM class dhcp_config* dhcp_client* - the VOM dhcp_client class maintains the lease data (which it reads on a dump) for clients to read Change-Id: I2a43463937cbd80c01d45798e74b21288d8b8ead Signed-off-by: Neale Ranns <neale.ranns@cisco.com>

2018-06-05bond: send gratuitous arp when the active slave went down in active-backup modeSteven8-31/+107
- Modify the API send_ip6_na and send_ip4_garp to take sw_if_index instead of vnet_hw_interface_t and add call to build_ethernet_rewrite to support subinterface/vlan - Add code to bonding driver to send an event to bond_process when the first interface becomes active or when the active interface is down - Create a bond_process to walk the interface and the corresponding subinterfaces to send garp/ip6_na when an event is received. - Minor cleanup in bonding/node.c Note: dpdk bonding driver does not send garp/ip6_na for subinterfaces. There is no attempt to fix it here. But the infra is now done and should be easy to add the support. Change-Id: If3ecc4cd0fb3051330f7fa11ca0dab3e18557ce1 Signed-off-by: Steven <sluong@cisco.com>

If the caller is the session owning thread or the main thread with a worker barrier sync (cli/api) add an event to the pending disconnects vector in the session node and entirely avoid using the event queue. Useful for bursts of disconnects (like an app detach). If disconnects come from a processes, be willing to retry enqueueing the disconnect to the event queue multiple times.

Improve "show l2fib" CLI to allow display of all entries, learned entries only, or added ovia CLI/API entries only. For added entry, show "no" under the age column to indicate entry does not age.

2018-05-27VPP-1294: add missing feature arc constraintDave Barach5-51/+114
the ip4-dhcp-client-detect feature MUST run prior to nat44-out2in, or inbound dhcp broadcast packets will be dropped. Certain dhcp servers answer lease renewal dhcp-request packets with broadcast dhcp-acks, leading to unrecoverable lease loss. In detail, this constraint: VNET_FEATURE_INIT (ip4_snat_out2in, static) = { .arc_name = "ip4-unicast", .node_name = "nat44-out2in", .runs_after = VNET_FEATURES ("acl-plugin-in-ip4-fa"), }; doesn't get the job done: ip4-unicast: [17] nat44-out2in [23] ip4-dhcp-client-detect [26] ip4-not-enabled Add a proper constraint: VNET_FEATURE_INIT (ip4_snat_out2in, static) = { .arc_name = "ip4-unicast", .node_name = "nat44-out2in", .runs_after = VNET_FEATURES ("acl-plugin-in-ip4-fa", "ip4-dhcp-client-detect"), }; and the interface feature order is OK, at least in this regard: ip4-unicast: [17] ip4-dhcp-client-detect [18] nat44-out2in [26] ip4-not-enabled We need to carefully audit (especially) the ip4-unicast feature arc, which has [gasp] 37 features on it!

2018-05-25bond: performance harvestingSteven4-133/+183
- hash is great. But it is a bit too slow for the DP. Use direct array indexing to quickly retrieve the slave interface. - the algorithm used by flow hash is great. But it is a bit too slow for the DP. Use l2_hash_hash() extracted from lb_hash.h which ECMP is using. It makes use of intrinsic crc32 instruction set. - shortcut modulo arithmetic when the operand is 2**x (where x up to 4) to avoid division instruction. - special case for link count == 1 in bond_tx_fn() - use clib_mem_unaligned to access data for the packet to avoid alignment error - Fix some typos for packet tracing.
