Victor Julien [Wed, 13 Sep 2023 05:01:53 +0000 (07:01 +0200)] 
packetpool: dynamic return threshold

Problem:

In pcap autofp mode, there is one threads reading packets (RX). These packets
are then passed on to worker threads. When these workers are done with a
packet, they return packets to the pcap reader threads packet pool, which is
the owner of the packets. Since this requires expensive synchronization between
threads, there is logic in place to batch this operation.

When the reader thread depletes its pool, it notifies the other threads that
it is starving and that a sync needs to happen asap. Then the reader enters
a wait state. During this time no new packets are read.

However, there is a problem with this approach. When the reader encountered
an empty pool, it would set an atomic flag that it needed a sync. The first
worker to return a packet to the pool would then set this flag, sync, and
unset the flag. This forced sync could result in just a single packet being
synchronized, or several. So if unlucky, the reader would just get a single
packet before hitting the same condition again.

Solution:

This patch updates the logic to use a new approach. Instead of using a
binary flag approach where the behavior only changes when the reader is
already starved, it uses a dynamic sync threshold that is controlled by
the reader. The reader keeps a running count of packets it its pool,
and calculates the percentage of available packets. This percentage is
then used to set the sync threshold.

When the pool is starved, it sets the threshold to 1 (sync for each packet).
After each successful get/sync the threshold is adjusted.

detect/flow: optimize only_stream/no_stream options

Until now the implementation would scan the stream, fallback to the
packet payload in exception cases, then keep track of where the match
was and in the flow match logic reject the match if it was in the wrong
buffer.

This patch simplifies this logic, by refusing to inspect the packet
payload when `only_stream` is set.

To do this the `only_stream`/`no_stream` options are now translated
to the pseudo protocols `tcp-stream` and `tcp-pkt` at parsing, so that
the `flow` keyword doesn't have to evaluate these conditions anymore.
