usbip: tools: add hint when no exported devices are found

2026-04-11T10:02:00+00:00

When refresh_exported_devices() finds no devices, it's helpful to inform users about potential causes. This could be due to: 1. The usbip driver module is not loaded. 2. No devices have been exported yet. Add an informational message to guide users when ndevs == 0. Also update the condition in usbip_host_driver_open() and usbip_device_driver_open() to check both ret and ndevs == 0, and change err() to info(). Message visibility by scenario: - usbipd (console mode): Show on console/serial, this allows instant visibility for debugging. - usbipd -D (daemon mode): Message logged to syslog, can keep logs for later traceability in production. Also can use "journalctl -f" to trace on console.

usbip: Use _FORTIFY_SOURCE=2 instead of (implicitly) =1

2023-05-29T14:11:30+00:00

_FORTIFY_SOURCE=2 uses more and stricter checks. This is what e.g. Debian recommends to build packages with. While at it fix a typo in the output of ./configure --help.

The commit e0546fd8b748 ("usbip: tools: Start using VUDC backend in usbip tools") implemented device mode for user space tools, however the corresponding options are not documented in man page. This commit documents the options and provides examples on device mode. Also the command `usbip port` is documented.

tools: usb: usbip: Replace HTTP links with HTTPS ones

2020-07-15T14:33:51+00:00

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.
