Type: feature When admin status is changed on an interface, add or delete the routes for the IPv4 addresses configured on that interface. This is already being done for IPv6 interface addresses. Change-Id: Ib1e7dc49c499921dd287e075640243520ffa5589 Signed-off-by: Matthew Smith <mgsmith@netgate.com>

2019-07-18vlib: convert frame_index into real pointersAndreas Schultz3-4/+4
The fast path almost always has to deal with the real pointers. Deriving the frame pointer from a frame_index requires a load of the 32bit frame_index from memory, another 64bit load of the heap base pointer and some calculations. Lets store the full pointer instead and do a single 64bit load only. This helps avoiding problems when the heap is grown and frames are allocated below vm->heap_aligned_base.

In contrast to the closing notification, whereby a transport informs the session layer that is beginning the closing procedure, this allows transports to notify the session layer of the fact that the transport is "fully" closed, i.e., it expects no more data.

2019-07-12ipsec: drop outbound ESP when no crypto alg setMatthew Smith4-5/+162
Type: fix If a tunnel interface has the crypto alg set on the outbound SA to IPSEC_CRYPTO_ALG_NONE and packets are sent out that interface, the attempt to write an ESP trailer on the packet occurs at the wrong offset and the vnet buffer opaque data is corrupted, which can result in a SEGV when a subsequent node attempts to use that data. When an outbound SA is set on a tunnel interface which has no crypto alg set, add a node to the ip{4,6}-output feature arcs which drops all packets leaving that interface instead of adding the node which would try to encrypt the packets.

2019-07-08map gbp papi: match endianess of f64Paul Vinciguerra1-2/+2
clib_net_to_host_f64, clib_host_to_net_f64 are now implemented as '=', https://gerrit.fd.io/r/#/c/20406/ set papi to match. - all f64 api references are now wrapped with clib_net_to_host_f64 or clib_host_to_net_f64. IEEE f64 endianess is not defined. If clib_net_to_host_f64 and clib_host_to_net_f64 are later defined in VPP as big-endian, it is a single character change in the papi vpp_serializer. Note: This breaks the api in a manner that would not be detected by the flag day initiative. The scope is small. This only impacts map.api, which applied the u64 transformation, while the gbp api uses '='. The implementation of "=" raises issues for the papi socket implementation if used between systems of differing endianess. See Vratko's comments. - Added get_f64_endian_value() to api to allow client to verify endianess of f64's.

Type: feature ip4_local_check_src() was overwriting vnet buffer opaque data on the adjacency for packets with "local" (dpo-receive) destination addresses. Retain the dpo receive index in vnet_buffer()->adj_index[VLIB_TX]. This can allow a graph node to distinguish the interface where the destination address is configured from the interface where the packet was received. This can be useful in correctly handling packets that have been sent to an address configured on a loopback interface.
