01c7a597 - fs: dlm: remove deprecated code parts

Mon, 06 Mar 2023 20:48:11 +0000

fs: dlm: remove deprecated code partsThis patch removes code parts which was declared deprecated bycommit 6b0afc0cc3e9 ("fs: dlm: don't use deprecated timeout features bydefault"). This contains the following dlm functionality:- start a cancel of a dlm request did not complete after certain timeout: The current way how dlm cancellation works and interfering with other dlm requests triggered by the user can end in an overlapping and returning in -EBUSY. The most user don't handle this case and are unaware that DLM can return such errno in such situation. Due the timeout the user are mostly unaware when this happens.- start a netlink warning messages for user space if dlm requests did not complete after certain timeout: This feature was never being built in the only known dlm user space side. As we are to remove the timeout cancellation feature we can directly remove this feature as well.There might be the possibility to bring the timeout cancellation featureback. However the current way of handling the -EBUSY case which is onlya software limitation and not a hardware limitation should be changed.We minimize the current code base in DLM cancellation feature to not haveto deal with those existing features while solving the DLM cancellationfeature in general.UAPI define DLM_LSFL_TIMEWARN is commented as deprecated and reservedvalue. We should avoid at first to give it a new meaning but letpossible users still compile by keeping this define. In far future wecan give this flag a new meaning. The same for the DLM_LKF_TIMEOUT lockrequest flag.Signed-off-by: Alexander Aring Signed-off-by: David Teigland List of files: /linux-6.15/fs/dlm/Makefile

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/fs/dlm/Makefile

3ae1acf9 - [DLM] add lock timeouts and warnings [2/6]

Fri, 18 May 2007 13:59:31 +0000

[DLM] add lock timeouts and warnings [2/6]New features: lock timeouts and time warnings. If the DLM_LKF_TIMEOUTflag is set, then the request/conversion will be canceled after waitingthe specified number of centiseconds (specified per lock). This featureis only available for locks requested through libdlm (can be enabled forkernel dlm users if there's a use for it.)If the new DLM_LSFL_TIMEWARN flag is set when creating the lockspace, thena warning message will be sent to userspace (using genetlink) after arequest/conversion has been waiting for a given number of centiseconds(configurable per node). The time warnings will be used in the futureto do deadlock detection in userspace.Signed-off-by: David Teigland Signed-off-by: Steven Whitehouse List of files: /linux-6.15/fs/dlm/Makefile

[DLM] Consolidate transport protocolsThis patch consolidates the TCP & SCTP protocols for the DLM into a single fileand makes it switchable at run-time (well, at least before the DLM actuallystarts up!)For RHEL5 this patch requires Neil Horman's patch that expands the in-kernelsocket API but that has already been twice ACKed so it should be OK.The patch adds a new lowcomms.c file that replaces the existing lowcomms-sctp.c& lowcomms-tcp.c files.Signed-off-By: Patrick Caulfield Signed-off-by: Steven Whitehouse List of files: /linux-6.15/fs/dlm/Makefile

[DLM] Add support for tcp communicationsThe following patch adds a TCP based communications layerto the DLM which is compile time selectable. The existing SCTPlayer gives the advantage of allowing multihoming, whereasthe TCP layer has been heavily tested in previous versions ofthe DLM and is known to be robust and therefore can be used asa baseline for performance testing.Signed-off-by: Patrick Caulfield Signed-off-by: Steven Whitehouse List of files: /linux-6.15/fs/dlm/Makefile
