2016-11-07usbip: deletion of incorrect socket descriptor checkingNobuo Iwata1-7/+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.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v4.4 merge window This pull request is large with a total of 136 non-merge commits. Because of its size, we will only describe the big things in broad terms. Many will be happy to know that dwc3 is now almost twice as fast after some profiling and speed improvements. Also in dwc3, John Youn from Synopsys added support for their new DWC USB3.1 IP Core and the HAPS platform which can be used to validate it. A series of patches from Robert Baldyga cleaned up uses of ep->driver_data as a flag for "claimed endpoint" in favor of the new ep->claimed flag. Sudip Mukherjee fixed a ton of really old problems on the amd5536udc driver. That should make a few people happy. Heikki Krogerus worked on converting dwc3 to the unified device property interface. Together with these, there's a ton of non-critical fixes, typos and stuff like that. Signed-off-by: Felipe Balbi <[email protected]>

2014-09-02tools: ffs-test: add compatibility code for old kernelsMichal Nazarewicz1-5/+107
If ffs-test is used with a kernel prior to 3.14, which do not support the new descriptors format, it will fail when trying to write the descriptors. Add a function that converts the new descriptors to the legacy ones and use it to retry writing the descriptors using the legacy format. Also add “-l” flag to ffs-test which will cause the tool to never try the new format and instead immediatelly try the legacy one. This should be useful to test whether parsing of the old format still works on given 3.14+ kernel. Signed-off-by: Michal Nazarewicz <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>

Commit [ac8dde11: “usb: gadget: f_fs: Add flags to descriptors block”] which introduced a new descriptor format for FunctionFS removed the usb_functionfs_descs_head structure, which is still used by ffs-test. tool. Convert ffs-test by converting it to use the new header format. For testing kernels prior to 3.14 (when the new format was introduced) and parsing of the legacy headers in the new kernels, provide a compilation flag to make the tool use the old format. Finally, include information as to when the legacy FunctionFS headers format has been deprecated (which is also when the new one has been introduced).
