From c24d64e3e53929f698e30552d270c43956e15f32 Mon Sep 17 00:00:00 2001 From: Andrei Gherzan Date: Thu, 26 Jan 2023 16:55:48 +0000 Subject: [SRU][Kinetic][PATCH v2 1/1] selftest: net: Improve IPV6_TCLASS/IPV6_HOPLIMIT tests apparmor compatibility BugLink: https://bugs.launchpad.net/bugs/2000709 "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.
