Introduces the option 'outputs.pcap-log.compression' which can be set to 'none' or 'lz4', plus options to set the compression level and to enable checksums. SCFmemopen is used to make pcap_dump() write to a buffer which is then compressed using liblz4.
Not sure about the Fedora case...

Like bug OISF#3340, SIP TCP transactions are logged with source and destination addresses swapped. But in this case logging logic needed to be reworkerd, because source and destination addresses were not logged correctly with regard to the flow direction. In this example below, there are 2 requests and 1 response but source and destination addresses are not correct. {"timestamp":"2019-11-17T07:43:57.799196-0600","flow_id":56712067097706,"pcap_cnt":5,"event_type":"sip","src_ip":"192.168.43.1","src_port":43168,"dest_ip":"192.168.43.100","dest_port":5060,"proto":"TCP", "sip":{"method":"REGISTER","uri":"sip:192.168.43.100;transport=TCP","version":"SIP/2.0","request_line":"REGISTER sip:192.168.43.100;transport=TCP SIP/2.0"}} {"timestamp":"2019-11-17T07:43:57.802382-0600","flow_id":56712067097706,"pcap_cnt":7,"event_type":"sip","src_ip":"192.168.43.1","src_port":43168,"dest_ip":"192.168.43.100","dest_port":5060,"proto":"TCP", "sip":{"version":"SIP/2.0","code":"200","reason":"OK","response_line":"SIP/2.0 200 OK"}} {"timestamp":"2019-11-17T07:43:57.806796-0600","flow_id":56712067097706,"pcap_cnt":9,"event_type":"sip","src_ip":"192.168.43.1","src_port":43168,"dest_ip":"192.168.43.100","dest_port":5060,"proto":"TCP", "sip":{"method":"REGISTER","uri":"sip:192.168.43.100;transport=TCP","version":"SIP/2.0","request_line":"REGISTER sip:192.168.43.100;transport=TCP SIP/2.0"}}
