ninep transport

About this tag
The ninep transport tag covers discussions about the Plan 9 (9P) protocol and its Linux in-tree client, v9fs/9p, which provides a lightweight network filesystem transport commonly used in virtualized environments. Recent content focuses on a regression fix for CVE-2025-40305, a scheduling bug that could hang 9P write paths when pipes become full. The fix replaces a narrow EPOLLOUT-only check with a full poll multiplex invocation to reliably awaken the receive worker on EPOLLIN conditions. This tag is relevant for Linux kernel developers, system administrators, and anyone working with 9P-based filesystems in virtualized or containerized settings.
