2021-11-22ipfix-export: support sending of ipv6 pktsPaul Atkins1-62/+176

Modify the ipfix_exporter to use ip_address instead of the ipv4 specific version.

2021-11-22ipfix-export: refactor params to the callback fnsPaul Atkins4-15/+7
When a new flow-report is created the caller provides 2 callback functions. These functions both take a pointer to the exporter, plus a pointer to the source and dest address. However the pointers to the address are not adding any value as these are always set to the src/dest addresses of the exporter (which is already being passed). Remove these parameters and leave the callback functions to get the addresses out of the exporter.

2021-11-22ipfix-export: Add APIs to get/send buffersPaul Atkins3-0/+234
The ipfix exporter should be doing most of the work of building packets and sending them rather than leaving every client of the exporter to do all the work themselves. Start to move towards that by adding APIs to get and send buffers. Store the state of this in new per thread data on the report so that we can send with minimal use of atomics. We do need an atomic for the sequence number in the packet though as that contains the number of data_records sent for the 'stream', not just for a single core. As the state is stored on the flow_report_t the caller needs to know which report they are using, so add a field to the args struct used to create the report that is used to pass back the report index on success.

2021-11-22ipfix-export: support creating multiple exportersPaul Atkins4-45/+169
The existing api set_ipfix_exporter only allows for the creation of a single exporter. In some cases it is desirable to export data to multiple different destinations. Allow users to create multiple ipfix exporters to support this. Add a new api that allows for the creation of multiple exporters, and store them in a pool of exporters. The exporter created by the old API will always be in index 0 of the pool. Exporters created by the new API will be given the next available index in the pool, and will return this index to the API caller so that they can track the exporter they created. The collector_address is the key for the exporter, so changes can be made by doing a further call to the API with the same collector_address.

2021-11-22ipfix-export: make stream fns exporter awarePaul Atkins1-18/+11

2021-11-22ipfix-export: refactor fields in flow_report_mainPaul Atkins4-87/+125
Pull out the fields in flow_report_main_t that are specific to a single exporter and move them into a new structure that represents an exporter. Add a pool of exporters to flow_report_main_t and do a pool_get() to get the entry at index 0, so that the existing users of the code need only change the path at which they access the old fields and have no need to make further code changes. In functions that were accessing the fields that now make up the ipfix_exporter create a local var that points to the first (always valid) exporter and use this as the base for the fields rather than finding them from flow_report_main. This is in preparation for supporting multiple flow_exporters. Note that at the moment the code supports multiple 'streams' for a given exporter, where each stream has its own source port, domain id and template space. But all streams within an exporter have the same destination address, so this is not the same as multiple exporters.

2021-11-19fib: Don't use [midchain] adjacencies to change an interface's feature arcNeale Ranns24-291/+352
Type: fix Using the adjacency to modify the interface's feature arc doesn't work, since there are potentially more than one adj per-interface. Instead have the interface, when it is created, register what the end node of the feature arc is. This end node is then also used as the interface's tx node (i.e. it is used as the adjacency's next-node). rename adj-midhcain-tx as 'tunnel-output', that's a bit more intuitive. There's also a fix in config string handling to: 1- prevent false sharing of strings when the end node of the arc is different. 2- call registered listeners when the end node is changed For IPSec the consequences are that one cannot provide per-adjacency behaviour using different end-nodes - this was previously done for the no-SA and an SA with no protection. These cases are no handled in the esp-encrypt node. Signed-off-by: Neale Ranns <neale@graphiant.com> Change-Id: If3a83d03a3000f28820d9a9cb4101d244803d084
