Punt_replicate(...) should not set *to_next[0] = bi0. The original buffer is enqueued separately in punt_dispatch_node(...)

Type: fix - doing so in MTU dec, means mtu_inc is broken - there's no need to. if a packet encounters ipX-rewrite a second time then it went through a tunnel the first time and is still locally originated.

2020-02-25vlib: Punt reason allocation listener enable/disable callbackNeale Ranns1-0/+2
Type: improvement allow clients that allocate punt reasons to pass a callback function that is invoked when the first/last client registers to use/listen on that punt reason. This allows the client to perform some necessary configs that might not otherwise be enabled. IPSec uses this callback to register the ESP proto and UDP handling nodes, that would not otherwise be enabled unless a tunnel was present.

2020-02-10ip6: fix l4 checksum with hop-by-hop headerMatthew Smith1-13/+23
L4 checksums for IPv6 should be calculated using a pseudo header that includes the source/destination addresses, payload length, and payload protocol. ip6_tcp_udp_icmp_compute_checksum() was using the payload length and protocol from the IPv6 header. If there is a hop-by-hop header (or any other extension header), the payload length used for the pseudo header should only include the upper layer header and payload and not the extension header bytes. Same deal with the protocol, the upper layer next header value should be used instead of the extension header.

2020-01-11ip: avoid fib lookup for consecutive pkts having same source IPNitin Saxena1-5/+5
Type: fix Fixes: be2286b0 This patch does following: - If terminating frame has consecutive packets with same source IP, this patch avoids fib lookup for those packets in ip4-local node. This drops cycle count for ip4-local node on both ARM and x86. It being done by enabling dead code in else {} case of ip4_local_check_src_x2() and ip4_local_check_src() functions. - In case all packets in terminating frame have unique source IP (e.g: incrementing), ip4-local is costlier by 2 cycles (broadwell) Change-Id: I472ddc324716cec8bfe601568b8aeb7565f97ab3 Signed-off-by: Nitin Saxena <nsaxena@marvell.com>

2019-11-26fib: Table ReplaceNeale Ranns2-131/+126
Type: feature from the API doc, a table replace is: " The use-case is that, for some unspecified reason, the control plane has a very different set of entries it wants in the table than VPP currently has. The CP would thus like to 'replace' VPP's current table only by specifying what the new set of entries shall be, i.e. it is not going to delete anything that already eixts. the CP delcartes the start of this procedure with this begin_replace API Call, and when it has populated all the entries it wants, it calls the below end_replace API. From this point on it is of coursce free to add and delete entries as usual. The underlying mechanism by which VPP implements this replace is purposefully left unspecified. " In the FIB, the algorithm is implemented using mark and sweep. Algorithm goes: 1) replace_begin: this marks all the entries in that table as 'stale' 2) download all the entries that should be in this table - this clears the stale flag on those entries 3) signal the table converged: ip_table_replace_end - this removes all entries that are still stale this procedure can be used when an agent first connects to VPP, as an alternative to dump and diff state reconciliation.
