"tcpdump" is used to capture traffic in these tests while using a random, temporary and not suffixed file for it. This can interfere with apparmor configuration where the tool is only allowed to read from files with 'known' extensions. The MINE type application/vnd.tcpdump.pcap was registered with IANA for pcap files and .pcap is the extension that is both most common but also aligned with standard apparmor configurations. See TCPDUMP(8) for more details. This improves compatibility with standard apparmor configurations by using ".pcap" as the file extension for the tests' temporary files.
