Hi, This project aims to add audit(4) support to NFS, which will allow auditd(8) to just run on the NFS server and audit all activities within the NFS network. Audit works mostly on the syscall level and NFS is implemented within the kernel, which means the NFS RPCs don't generate any audit records on the server. Note that audit(4) can still be used on the NFS network but auditd(8) must run on every NFS client. This week I made the following progress: * generate audit tokens for NFS RPC events. * added NFSRPC audit events to kernel audit_bsm_db Currently, I am: * looking into audit kernel code and userspace contrib/openbsm for inserting event-class mapping for NFS RPC events to kernel db. * do audit preselection based on audit_control * looking into net/libnfs port to write tests for NFS audit. Please, do Check this project on Github: https://github.com/shivankgarg98/freebsd/tree/user/shivank/nfs_audit Project wiki: https://wiki.freebsd.org/SummerOfCode2020Projects/AddAuditSupportToNFS Please feel free to share your ideas and feedback on this project.
