Type: fix Presently a local label associated with an attached or connected prefix will link to the glean.

There could be a race condition where two fragments of one chain end up at the same time on different workers, one overwriting others hash entry. Add a check for that and restart processing on the unlucky worker who ends up being second from hash table POV. This will then result in a proper handover to worker now owning this reassembly.

2021-12-04ipsec: fix async buffer leakMatthew Smith3-3/+2
Type: fix Fixes: f16e9a5507 If an attempt to submit an async crypto frame fails, the buffers that were added to the frame are supposed to be dropped. This was not happening and they are leaking, resulting in buffer exhaustion. There are two issues: 1. The return value of esp_async_recycle_failed_submit() is used to figure out how many buffers should be dropped. That function calls vnet_crypto_async_reset_frame() and then returns f->n_elts. Resetting the frame sets n_elts to 0. So esp_async_recycle_failed_submit() always returns 0. It is safe to remove the call to reset the frame because esp_async_recycle_failed_submit() is called in 2 places and a call to reset the frame is made immediately afterwards in both cases - so it is currently unnecessary anyway. 2. An array and an index are passed to esp_async_recycle_failed_submit(). The index should indicate the position in the array where indices of the buffers contained in the frame should be written. Across multiple calls, the same index value (n_sync) is passed. This means each call may overwrite the same entries in the array with the buffer indices in the frame rather than appending them to the entries which were written earlier. Pass n_noop as the index instead of n_sync. Change-Id: I525ab3c466965446f6c116f4c8c5ebb678a66d84 Signed-off-by: Matthew Smith <mgsmith@netgate.com>

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.
