The Windows Protocol Test Suites is an open source, cross platform application designed to enable the testing of implementations of selected Windows protocols. It is used both internally at Microsoft to ensure that protocol behaviors are in line with the publicly available protocol specifications, and by protocol implementers to test their own protocol behaviors. In this talk, we'll provide a deep dive into the architecture and design of the Test Suites, discussing some of the design decisions.

To implement SMB2 unix extensions, smbd needs to implement ntfs reparse points to present symlinks, sockets and other special files to clients. This talk will present an overview of what reparse points are at their core and where Samba stands to implement them. Also, it will highlight the current status of the Linux kernel SMB client implementation regarding reparse points and special files over SMB2.

High-performance computing applications, web-scale storage systems, and modern enterprises increasingly have the need for a data architecture that will unify at the edge, and in data centers, and clouds. These organizations with massive-scale data requirements need the performance of a parallel file system coupled with a standards-based solution that will be easy to deploy on machines with diverse security and build environments.

Standards-Based Parallel Global File System - No Proprietary Clients

With the increasing amount of network throughput, we'll reach a point where a data copies are too much for a single cpu core to handle. This talk gives an overview about how the io_uring infrastructure of the Linux kernel could be used in order to avoid copying data, as well as spreading the load between cpu cores. A prototype for this exists for quite some time and shows excellent results.

The Linux SMB3.1.1 client continues to be one of the most active filesystems in Linux with many improvements added each year, enhancing its ability to securely, reliably and efficiently access remote data. This presentation will cover new features added to the Linux client, and new features you can expect to see over the coming year. Whether accessing data from the smallest devices or the largest (and even the cloud), getting at remote files matters.

Current clustered Samba uses its homegrown distributed database "ctdb" as a storage backend for maintaining coherent fileserver state. ctdb predates most cloudy distributed NoSQL databases that came to rise on the wings of the likes of Google Bigtable, Amazon Dynamo, Apache Cassandra and so on in the 2000's. It has worked extremely well for the high performance scaleout NAS usecase, but the emerging shift to the cloud entails serious scalability, elasticity and managability challenges. So are there alternatives to ctdb?
