This week I did the following- * Understand and wrote TrustedBSD MAC framework bits for the mac_ipacl module. * Read the implementation of ifconfig and network modules in FreeBSD. (sys/netinet and sys/netinet6) * Checked the flow of code in the network modules(mainly in.c) by seeing printf logs. * I added MAC Framework checks in prison_check.c and tried simple tests with it. But I was going on the wrong path. So, had to check with my logic again. Do Check this project on Github: https://github.com/shivankgarg98/freebsd/tree/shivank_MACPolicyIPAddressJail/sys/security/mac_ipacl FreeBSD wiki: https://wiki.freebsd.org/SummerOfCode2019Projects/MACPolicyIPAddressJail Please feel free to share your ideas and feedback on this project.
