b2441318 - License cleanup: add SPDX GPL-2.0 license identifier to files with no license

Wed, 01 Nov 2017 14:07:57 +0000

License cleanup: add SPDX GPL-2.0 license identifier to files with no licenseMany source files in the tree are missing licensing information, whichmakes it harder for compliance tools to determine the correct license.By default all files without license information are under the defaultlicense 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 bindingshorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart andPhilippe Ombredanne.How this work was done:Patches were generated and checked against linux-4.14-rc6 for a subset ofthe 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 caseswhere non-standard license headers were used, and references to licensehad to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied toa file was done in a spreadsheet of side by side results from of theoutput of two independent scanners (ScanCode & Windriver) producing SPDXtag:value files created by Philippe Ombredanne. Philippe prepared thebase 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 filesassessed. Kate Stewart did a file by file comparison of the scannerresults in the spreadsheet to determine which SPDX license identifier(s)to be applied to the file. She confirmed any determination that was notimmediately 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 licenseidentifiers 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 thespreadsheet to determine the SPDX license identifiers to apply to thesource files by Kate, Philippe, Thomas and, in some cases, confirmationby lawyers working with the Linux Foundation.Kate also obtained a third independent scan of the 4.13 code base fromFOSSology, and compared selected files where the other two scannersdisagreed against that SPDX file, to see if there was new insights. TheWindriver scanner is based on an older version of FOSSology in part, sothey are related.Thomas did random spot checks in about 500 files from the spreadsheetsfor the uapi headers and agreed with SPDX license identifier in thefiles he inspected. For the non-uapi files Thomas did random spot checksin about 15000 files.In initial set of patches against 4.14-rc6, 3 files were found to havecopy/paste license identifier errors, and have been fixed to reflect thecorrect identifier.Additionally Philippe spent 10 hours this week doing a detailed manualinspection and review of the 12,461 patched files from the initial patchversion 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 correctThis produced a worksheet with 20 files needing minor correction. Thisworksheet was then exported into 3 different .csv files for thedifferent types of files to be modified.These .csv files were then reviewed by Greg. Thomas wrote a script toparse the csv files and add the proper SPDX tag to the file, in theformat that the file expected. This script was further refined by Gregbased on the output to detect more types of files automatically and todistinguish between header and source .c files (which need differentcomment types.) Finally Greg ran the script using the .csv files togenerate the patches.Reviewed-by: Kate Stewart Reviewed-by: Philippe Ombredanne Reviewed-by: Thomas Gleixner Signed-off-by: Greg Kroah-Hartman List of files: /linux-6.15/drivers/target/Makefile

7c9e7a6f - target: Add a user-passthrough backstore

Wed, 01 Oct 2014 23:07:05 +0000

target: Add a user-passthrough backstoreAdd a LIO storage engine that presents commands to userspace for execution.This would allow more complex backstores to be implemented out-of-kernel,and also make experimentation a-la FUSE (but at the SCSI level -- "SUSE"?)possible.It uses a mmap()able UIO device per LUN to share a command ring and dataarea. The commands are raw SCSI CDBs and iovs for in/out data. The commandring is also reused for returning scsi command status and optional sensedata.This implementation is based on Shaohua Li's earlier version but heavilymodified. Differences include:* Shared memory allocated by kernel, not locked-down user pages* Single ring for command request and response* Offsets instead of embedded pointers* Generic SCSI CDB passthrough instead of per-cmd specialization in ring format.* Uses UIO device instead of anon_file passed in mailbox.* Optional in-kernel handling of some commands.The main reason for these differences is to permit greater resiliencyif the user process dies or hangs.Things not yet implemented (on purpose):* Zero copy. The data area is flexible enough to allow page flipping or backend-allocated pages to be used by fabrics, but it's not clear these are performance wins. Can come later.* Out-of-order command completion by userspace. Possible to add by just allowing userspace to change cmd_id in rsp cmd entries, but currently not supported.* No locks between kernel cmd submission and completion routines. Sounds like it's possible, but this can come later.* Sparse allocation of mmaped area. Current code vmallocs the whole thing. If the mapped area was larger and not fully mapped then the driver would have more freedom to change cmd and data area sizes based on demand.Current code open issues:* The use of idrs may be overkill -- we maybe can replace them with a simple counter to generate cmd_ids, and a hash table to get a cmd_id's associated pointer.* Use of a free-running counter for cmd ring instead of explicit modulo math. This would require power-of-2 cmd ring size.(Add kconfig depends NET - Randy)Signed-off-by: Andy Grover Signed-off-by: Nicholas Bellinger List of files: /linux-6.15/drivers/target/Makefile

cbf031f4 - target: Add support for EXTENDED_COPY copy offload emulation

Tue, 20 Aug 2013 22:38:55 +0000

target: Add support for EXTENDED_COPY copy offload emulationThis patch adds support for EXTENDED_COPY emulation from SPC-3, thatenables full copy offload target support within both a single virtualbackend device, and across multiple virtual backend devices. It alsofunctions independent of target fabric, and supports copy offloadacross multiple target fabric ports.This implemenation supports both EXTENDED_COPY PUSH and PULL modelsof operation, so the actual CDB may be received on either source ordesination logical unit.For Target Descriptors, it currently supports the NAA IEEE RegisteredExtended designator (type 0xe4), which allows the reference of targetports to occur independent of fabric type using EVPD 0x83 WWNs.For Segment Descriptors, it currently supports copy from block toblock (0x02) mode.It also honors any present SCSI reservations of the destination targetport. Note that only Supports No List Identifier (SNLID=1) mode issupported.Also included is basic RECEIVE_COPY_RESULTS with service action typeOPERATING PARAMETERS (0x03) required for SNLID=1 operation.v3 changes: - Fix incorrect return type in target_do_receive_copy_results() (Fengguang)v2 changes: - Use target_alloc_sgl() instead of transport_generic_get_mem() - Convert debug output to use pr_debug() - Convert target_xcopy_parse_target_descriptors() NAA IEEN WWN dump to use 0x%16phN format specification - Drop unnecessary xcopy_pt_cmd->xpt_passthrough_wsem, and associated usage in xcopy_pt_write_pending() and target_xcopy_issue_pt_cmd() - Add check for unsupported EXTENDED_COPY(LID4) service action bits in target_do_xcopy()Cc: Christoph Hellwig Cc: Hannes Reinecke Cc: Martin Petersen Cc: Chris Mason Cc: Roland Dreier Cc: Zach Brown Cc: James Bottomley Cc: Nicholas Bellinger Signed-off-by: Nicholas Bellinger List of files: /linux-6.15/drivers/target/Makefile

3699d92a - [SCSI] tcm_fc: Adding FC_FC4 provider (tcm_fc) for FCoE target (TCM - target core) support

Mon, 18 Apr 2011 23:24:14 +0000

[SCSI] tcm_fc: Adding FC_FC4 provider (tcm_fc) for FCoE target (TCM - target core) supportThis is a comprehensive patch for FC-FC4 provider. tcm_fc is a FC-FC4provider which glues target core (TCM) with Fiber channel library(libfc). tcm_fc uses existing FC4 provider hooks from Fiber channellibrary. This Fiber channel library is used by FCoE (transport - FCover Ethernet) protocol driver as well.Combination of modules such as Fiber channel library, tcm_fc, TCMtarget core, and FCoE protocol driver enables functional FCoE target.This patch includes initial commit for tcm_fc plus additionalenhancement, bug fixes.This tcm_fc module essentially contains 3 entry points such as "prli","prlo", "recv". When process login request (ELS_PRLI) request isreceived, Fiber channel library (libfc) module calls passive providers(FC-FC4, tcm_fc) (if any registered) "prli" function. Likewise whenLOGO request is received, "prlo" function of passive provider isinvoked by libfc. For all other request (e.g. any read/write, taskmanagement, LUN inquiry commands), "recv" function of passiverprovider is invoked by libfc. Those passive providers "prli, prlo,recv" functions interact with TCM target core for requested operation.This module was primarily developed by "Joe Eykholt" and there weresignificant contributions from the people listed under signed-off.Signed-off-by: Joe Eykholt Signed-off-by: Nicholas A.
