2024-09-11tools: usb: p9_fwd: wrap USBG shell command examples in literal code blocksBagas Sanjaya1-3/+3
Stephen Rothwell reported htmldocs warning when merging usb tree: Documentation/filesystems/9p.rst:99: ERROR: Unexpected indentation. That's because Sphinx tries rendering p9_fwd.py output as a grid table instead. Wrap shell commands in "USBG Example" section in literal code blocks to fix above warning and to be in line with rest of commands in the doc.

2024-09-03tools: usb: p9_fwd: add usb gadget packet forwarder scriptMichael Grzeschik1-0/+41
This patch is adding an small python tool to forward 9pfs requests from the USB gadget to an existing 9pfs TCP server. Since currently all 9pfs servers lack support for the usb transport this tool is an useful helper to get started. Refer the Documentation section "USBG Example" in Documentation/filesystems/9p.rst on how to use it.

2024-09-03net/9p/usbg: Add new usb gadget function transportMichael Grzeschik1-1/+16
Add the new gadget function for 9pfs transport. This function is defining an simple 9pfs transport interface that consists of one in and one out endpoint. The endpoints transmit and receive the 9pfs protocol payload when mounting a 9p filesystem over usb.

2023-04-10fs/9p: Rework cache modes and add new options to DocumentationEric Van Hensbergen1-13/+37
Switch cache modes to a bit-mask and use legacy cache names as shortcuts. Update documentation to include information on both shortcuts and bitmasks. This patch also fixes missing guards related to fscache. Update the documentation for new mount flags and cache modes. Signed-off-by: Eric Van Hensbergen <ericvh@kernel.org>
2023-03-27fs/9p: allow disable of xattr support on mountEric Van Hensbergen1-0/+2
xattr creates a lot of additional messages for 9p in the current implementation. This allows users to conditionalize xattr support on 9p mount if they are on a connection with bad latency. Using this flag is also useful when debugging other aspects of 9p as it reduces the noise in the trace files.

2020-07-13Replace HTTP links with HTTPS ones: 9P FILE SYSTEMAlexander A. Klimov1-1/+1
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.
