Fri, 27 Mar 2026 07:16:49 +0100

sparc: move the XOR code to lib/raid/Move the optimized XOR into lib/raid and include it it in xor.ko insteadof always building it into the main kernel image.The code should probably be split into separate files for the twoimplementations, but for now this just does the trivial move.Link: https://lkml.kernel.org/r/20260327061704.3707577-18-hch@lst.deSigned-off-by: Christoph Hellwig Reviewed-by: Eric Biggers Tested-by: Eric Biggers Cc: Albert Ou Cc: Alexander Gordeev Cc: Alexandre Ghiti Cc: Andreas Larsson Cc: Anton Ivanov Cc: Ard Biesheuvel Cc: Arnd Bergmann Cc: "Borislav Petkov (AMD)" Cc: Catalin Marinas Cc: Chris Mason Cc: Christian Borntraeger Cc: Dan Williams Cc: David S.

Tue, 05 Aug 2025 11:25:40 +0200

sparc: Drop the "-ansi" from the asflagsIn the very early kernel 1.x days, assembler files were pre-processedwith the "-traditional" flag. With kernel 1.1.85, the sparc subsystemwas changed to use "-ansi" instead while the other parts of the kernelcontinued to use "-traditional". That "-traditional" got removed fromthe other architectures in the course of time, but the sparc partkept the "-ansi" until today.This is bad since it comes with some disadvantages nowadays: You haveto make sure to not include any header that contains a "//" C++ commentby accident (there are now some in the tree that use these for SPDXidentifiers for example), and with "-ansi" we also do not get thepre-defined __ASSEMBLER__ macro which we'd like to use instead of thekernel-only __ASSEMBLY__ macro in the future.Since there does not seem to be any compelling reason anymore to use"-ansi" nowadays, let's simply drop the "-ansi" flag from the sparcsubsystem now to get rid of those disadvantages.Signed-off-by: Thomas Huth Reviewed-by: Arnd Bergmann Reviewed-by: Andreas Larsson Tested-by: Andreas Larsson Signed-off-by: Andreas Larsson List of files: /linux/arch/sparc/lib/Makefile

Merge tag 'libcrypto-updates-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linuxPull crypto library updates from Eric Biggers: "This is the main crypto library pull request for 6.17. The main focus this cycle is on reorganizing the SHA-1 and SHA-2 code, providing high-quality library APIs for SHA-1 and SHA-2 including HMAC support, and establishing conventions for lib/crypto/ going forward: - Migrate the SHA-1 and SHA-512 code (and also SHA-384 which shares most of the SHA-512 code) into lib/crypto/. This includes both the generic and architecture-optimized code. Greatly simplify how the architecture-optimized code is integrated. Add an easy-to-use library API for each SHA variant, including HMAC support. Finally, reimplement the crypto_shash support on top of the library API. - Apply the same reorganization to the SHA-256 code (and also SHA-224 which shares most of the SHA-256 code). This is a somewhat smaller change, due to my earlier work on SHA-256. But this brings in all the same additional improvements that I made for SHA-1 and SHA-512. There are also some smaller changes: - Move the architecture-optimized ChaCha, Poly1305, and BLAKE2s code from arch/$(SRCARCH)/lib/crypto/ to lib/crypto/$(SRCARCH)/. For these algorithms it's just a move, not a full reorganization yet. - Fix the MIPS chacha-core.S to build with the clang assembler. - Fix the Poly1305 functions to work in all contexts. - Fix a performance regression in the x86_64 Poly1305 code. - Clean up the x86_64 SHA-NI optimized SHA-1 assembly code. Note that since the new organization of the SHA code is much simpler, the diffstat of this pull request is negative, despite the addition of new fully-documented library APIs for multiple SHA and HMAC-SHA variants. These APIs will allow further simplifications across the kernel as users start using them instead of the old-school crypto API.

Thu, 24 Apr 2025 02:20:37 +0200

sparc/crc: drop "glue" from filenamesThe use of the term "glue" in filenames is a Crypto API-ism that rarelyshows up elsewhere in lib/ or arch/*/lib/. I think adopting it therewas a mistake. The library just uses standard functions, so the amountof code that could be considered "glue" is quite small. And while oftenthe C functions just wrap the assembly functions, there are also caseslike crc32c_arch() in arch/x86/lib/crc32-glue.c that blur the line byin-lining the actual implementation into the C function. That's not"glue code", but rather the actual code.Therefore, let's drop "glue" from the filenames and instead use e.g.crc32.c instead of crc32-glue.c.Reviewed-by: "Martin K.

This allows it to be used without goingthrough the crypto API. It remains usable via the crypto API too viathe shash algorithms that use the library interface. Thus all thearch-specific "shash" code becomes unnecessary and is removed.Note: to see the diff from arch/sparc/crypto/crc32c_glue.c toarch/sparc/lib/crc32_glue.c, view this commit with 'git show -M10'.Reviewed-by: Ard Biesheuvel Link: https://lore.kernel.org/r/20241202010844.144356-11-ebiggers@kernel.orgSigned-off-by: Eric Biggers List of files: /linux/arch/sparc/lib/Makefile

b24413180f5600bcb3bb70fbed5cf186b60864bd - License cleanup: add SPDX GPL-2.0 license identifier to files with no license

Wed, 01 Nov 2017 15:07:57 +0100

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/arch/sparc/lib/Makefile
