Efstratios Karatzas's project extended the FreeBSD NFS server to support security auditing (logging) of client activity -- before his work, as with most systems out there, FreeBSD logged only local file system activity. This work is valuable and timely: FreeBSD is used widely as a file server, as well as being the foundation OS for numerous storage products including NetApp, Isilon, Panasas, and the open source FreeNAS. We look forward to shipping this feature in FreeBSD 9.0, as the patches mature, as well as seeing Efstratios at EuroBSDCon in Karlsruhe this autumn!Zheng Liu spent the summer working with veteran FreeBSD kernel hacker John Baldwin on enhancing FreeBSD’s ext2fs to support preallocation and implementing read-only support for ext4 file systems. This was a particularly challenging project and Zheng Liu’s efforts at benchmarking his new implementation and documenting his work were particularly appreciated. This work will likely be included in an upcoming FreeBSD release.David Forsythe returned to the Google Summer of Code program this year to work on developing a robust library with a clean API to manage FreeBSD packages. The goal is to abstract out some of the capabilities used in the current package tools into a library so they can be easily reused by new tools. David has even started assembling some replacements for the existing package tools implemented on top of his new library, and did a great job coordinating with other students and developers working in this area over the summer.
