kernel/tools/usb/usbip/src/usbip_bind.c, branch linux-5.1.yHosts the 0x221E linux distro kernel.https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-5.1.y2018-01-22T14:34:37Zusbip: prevent bind loops on devices attached to vhci_hcd2018-01-22T14:34:37ZShuah Khanshuahkh@osg.samsung.com2018-01-17T19:07:30Zurn:sha1:ef54cf0c600fb8f5737fb001a9e357edda1a1de8
usbip host binds to devices attached to vhci_hcd on the same server
when user does attach over localhost or specifies the server as the
remote.
usbip attach -r localhost -b busid
or
usbip attach -r servername (or server IP)
Unbind followed by bind works, however device is left in a bad state with
accesses via the attached busid result in errors and system hangs during
shutdown.
Fix it to check and bail out if the device is already attached to vhci_hcd.

usbip: move usbip userspace code out of staging2014-08-25T17:38:56ZValentina Maneavalentina.manea.m@gmail.com2014-08-20T04:30:59Zurn:sha1:588b48caf65c4a92af567948ec0025065e749ddf
At this point, USB/IP userspace code is fully functional
and can be moved out of staging.
