License cleanup: add SPDX GPL-2.0 license identifier to files with no license 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.

NFC: Digital Protocol stack implementation This is the initial commit of the NFC Digital Protocol stack implementation. It offers an interface for devices that don't have an embedded NFC Digital protocol stack. The driver instantiates the digital stack by calling nfc_digital_allocate_device(). Within the nfc_digital_ops structure, the driver specifies a set of function pointers for driver operations. These functions must be implemented by the driver and are: in_configure_hw: Hardware configuration for RF technology and communication framing in initiator mode. This is a synchronous function. in_send_cmd: Initiator mode data exchange using RF technology and framing previously set with in_configure_hw. The peer response is returned through callback cb. If an io error occurs or the peer didn't reply within the specified timeout (ms), the error code is passed back through the resp pointer. This is an asynchronous function. tg_configure_hw: Hardware configuration for RF technology and communication framing in target mode. This is a synchronous function. tg_send_cmd: Target mode data exchange using RF technology and framing previously set with tg_configure_hw. The peer next command is returned through callback cb. If an io error occurs or the peer didn't reply within the specified timeout (ms), the error code is passed back through the resp pointer. This is an asynchronous function. tg_listen: Put the device in listen mode waiting for data from the peer device. This is an asynchronous function. tg_listen_mdaa: If supported, put the device in automatic listen mode with mode detection and automatic anti-collision. In this mode, the device automatically detects the RF technology and executes the anti-collision detection using the command responses specified in mdaa_params. The mdaa_params structure contains SENS_RES, NFCID1, and SEL_RES for 106A RF tech. NFCID2 and system code (sc) for 212F and 424F. The driver returns the NFC-DEP ATR_REQ command through cb. The digital stack deducts the RF tech by analyzing the SoD of the frame containing the ATR_REQ command. This is an asynchronous function. switch_rf: Turns device radio on or off. The stack does not call explicitly switch_rf to turn the radio on. A call to in|tg_configure_hw must turn the device radio on. abort_cmd: Discard the last sent command. Then the driver registers itself against the digital stack by using nfc_digital_register_device() which in turn registers the digital stack against the NFC core layer. The digital stack implements common NFC operations like dev_up(), dev_down(), start_poll(), stop_poll(), etc. This patch is only a skeleton and NFC operations are just stubs.

NFC Digital: Add initiator NFC-DEP support This adds support for NFC-DEP protocol in initiator mode for NFC-A and NFC-F technologies. When a target is detected, the process flow is as follow: For NFC-A technology: 1 - The digital stack receives a SEL_RES as the reply of the SEL_REQ command. 2 - If b7 of SEL_RES is set, the peer device is configure for NFC-DEP protocol. NFC core is notified through nfc_targets_found(). Execution continues at step 4. 3 - Otherwise, it's a tag and the NFC core is notified. Detection ends. 4 - The digital stacks sends an ATR_REQ command containing a randomly generated NFCID3 and the general bytes obtained from the LLCP layer of NFC core. For NFC-F technology: 1 - The digital stack receives a SENSF_RES as the reply of the SENSF_REQ command. 2 - If B1 and B2 of NFCID2 are 0x01 and 0xFE respectively, the peer device is configured for NFC-DEP protocol. NFC core is notified through nfc_targets_found(). Execution continues at step 4. 3 - Otherwise it's a type 3 tag. NFC core is notified. Detection ends. 4 - The digital stacks sends an ATR_REQ command containing the NFC-F NFCID2 as NFCID3 and the general bytes obtained from the LLCP layer of NFC core. For both technologies: 5 - The digital stacks receives the ATR_RES response containing the NFCID3 and the general bytes of the peer device. 6 - The digital stack notifies NFC core that the DEP link is up through nfc_dep_link_up(). 7 - The NFC core performs data exchange through tm_transceive(). 8 - The digital stack sends a DEP_REQ command containing an I PDU with the data from NFC core. 9 - The digital stack receives a DEP_RES command 10 - If the DEP_RES response contains a supervisor PDU with timeout extension request (RTOX) the digital stack sends a DEP_REQ command containing a supervisor PDU acknowledging the RTOX request. The execution continues at step 9. 11 - If the DEP_RES response contains an I PDU, the response data is passed back to NFC core through the response callback. The execution continues at step 8.
