| | | | | | | | | | | Update README file: - remove outdated parts - clarify terminology and general structure - add some description of vUDC Signed-off-by: Krzysztof Opasiak <k.opasiak@samsung.com> Acked-by: Shuah Khan <shuahkh@osg.samsung.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* tools: usb: usbip: Add simple script to show how to setup vUDCKrzysztof Opasiak2017-01-101-0/+107
| | | | | | | | | | | | Add some simple script which creates a USB gadget using ConfigFS and then exports it using vUDC. This may be useful for people who just started playing with USB/IP and vUDC as it shows exact steps how to setup all stuff.

* usbip: deletion of incorrect socket descriptor checkingNobuo Iwata2016-11-071-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes checking of socket descriptor value in daemons. It was checked to be less than FD_SETSIZE(1024 usually) but it's not correct. To be exact, the maximum value of descriptor comes from rlimit(RLIMIT_NOFILE). Following kernel code determines the value : get_unused_fd_flags() : fs/files.c __alloc_fd() : fs/files.c expand_files() : fs/files.c The defalut (soft limit) is defines as INR_OPEN_CUR(1024) in include/linux/fs.h which is referenced form INIT_RLIMS in include/asm-generic/resource.h. The value may be modified with ulimt, sysctl, security configuration and etc. With the kernel code above, when socket() system call returns positive value, the value must be within rlimit(RLIMIT_NOFILE). No extra checking is needed when socket() returns positive. Without 'usbip: vhci number of ports extension' patch set, there's no practical problem because of number of USB port restriction. With the patch set, the value of socket descriptor can exceed FD_SETSIZE(1024 usually) if the rlimit is changed.

* usbip: tools: Add vudc backend to usbip toolsKrzysztof Opasiak2016-04-264-0/+201
| | | | | | | | | | | | | | | | | | | | | Adds an equivalent of usbip_host_driver for the vudc. Most of the code is already shared, but this adds some vudc specific code for getting information about devices.
