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. Til this I week, I made the following progress: * Fixed the AUDIT_NFSARG_UPATH1 to avoid unlocking/relocking of vnode for locked vnode. * Followed up on NFSv3 Audit(4) support revision here: https://reviews.freebsd.org/D25869 * Started Auditing NFSv4 Sub-operations: https://github.com/shivankgarg98/freebsd/compare/user/shivank/nfs_audit_review2...shivankgarg98:user/shivank/nfsv4_audit Currently, I'm: * Developing TestSuite for NFSv4 Simultaneously for audited sub-ops. * auditing remaining NFSv4 services. Please, do Check this project on Github: https://github.com/shivankgarg98/freebsd/tree/user/shivank/nfs_audit NFSv4 audit feature branch: https://github.com/shivankgarg98/freebsd/tree/user/shivank/nfsv4_audit Project wiki: https://wiki.freebsd.org/SummerOfCode2020Projects/AddAuditSupportToNFS TestSuite: https://github.com/shivankgarg98/NFSAuditTestSuite Please feel free to share your ideas and feedback on this project.
