* | License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseGreg Kroah-Hartman2017-11-0215-0/+15
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

* usbip: auto retry for concurrent attachNobuo Iwata2017-08-311-15/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds recovery from false busy state on concurrent attach operation. The procedure of attach operation is as below. 1) Find an unused port in /sys/devices/platform/vhci_hcd/status. (userspace) 2) Request attach found port to driver through /sys/devices/platform/vhci_hcd/attach. (userspace) 3) Lock table, reserve requested port and unlock table. (vhci driver) Attaching more than one remote devices concurrently, same unused port number will be found in step-1. Then one request will succeed and others will fail even though there are some unused ports. With this patch, driver returns EBUSY when requested port has already been used. In this case, attach command retries from step-1: finding another unused port. If there's no unused port, the attach operation will fail in step-1. Otherwise it retries automatically using another unused port. vhci-hcd's interface (only errno) is changed as following. Current errno New errno Condition EINVAL same as left specified port number is in invalid range EAGAIN same as left platform_get_drvdata() failed EINVAL same as left specified socket fd is not valid EINVAL EBUSY specified port status is not free The errno EBUSY was not used in userspace src/usbip_attach.c:import_device(). It is needed to distinguish the condition to be able to retry from other unrecoverable errors. It is possible to avoid this failure by introducing userspace exclusive control. But it's exaggerated for this special condition. The locking itself has done in driver. As an alternate solution, userspace doesn't specify port number, driver searches unused port and it returns port number to the userspace. With this solution, the interface is much different than this patch.

* 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.

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 <balbi@ti.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 <mina86@mina86.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
