Explore the challenges and solutions for mounting and interacting with untrusted file systems in a Linux environment during this 40-minute conference talk from the Linux Plumbers Conference. Gain insights into the security risks associated with USB sticks, VM images, and unprivileged containers. Learn about existing implementations, technical hurdles, and future challenges in safely handling untrusted file systems. Discover the speaker's goal of uniting various Linux ecosystem groups to address this issue and initiate discussions on potential solutions. The talk covers topics such as threat modeling, metadata security, UML, LKF, common bug locations, network file systems, client system drivers, GVFS, and containers.
