After a year of implementation progress of the The SMB3 .1.1 POSIX Extensions, a set of protocol extensions to allow for optimal Linux and Unix interoperability with NAS and Cloud file servers

- what is the current status

- what have we learned

- what has changed in the protocol specification in the past year

- what advice do we have for implementers

- and users …

These extensions greatly improve the experience for users of Linux. This presentation will review the state of the protocol extensions and their current implementation in the Linux kernel and Samba among others, and provide an opportunity for feedback and suggestions for additions to the POSIX extensions.

This has been an exciting year with many improvements to the implementations of the SMB3.1.1 POSIX Extensions in Samba and Linux!

Learning Objectives: 1) What is the current status of Linux interoperability with various SMB3.1.1 servers?; 2) How have the protocol extensions for Linux/POSIX progressed over the past year? What has changed? What works?; 3) What are suggestions for implementors of SMB3.1.1 servers?; 4) What is useful information for users to know to try these extensions?; 5) How do new Linux file system features map to these extensions?
