32164845 - kbuild: use obj-y instead extra-y for objects placed at the head

Sat, 24 Sep 2022 18:19:14 +0000

kbuild: use obj-y instead extra-y for objects placed at the headThe objects placed at the head of vmlinux need special treatments: - arch/$(SRCARCH)/Makefile adds them to head-y in order to place them before other archives in the linker command line. - arch/$(SRCARCH)/kernel/Makefile adds them to extra-y instead of obj-y to avoid them going into built-in.a.This commit gets rid of the latter.Create vmlinux.a to collect all the objects that are unconditionallylinked to vmlinux. The objects listed in head-y are moved to the headof vmlinux.a by using 'ar m'.With this, arch/$(SRCARCH)/kernel/Makefile can consistently use obj-yfor builtin objects.There is no *.o that is directly linked to vmlinux. Drop unneeded codein scripts/clang-tools/gen_compile_commands.py.$(AR) mPi needs 'T' to workaround the llvm-ar bug.

alpha: Implement CPU vulnerabilities sysfs functions.Implement the CPU vulnerabilty show functions for meltdown, spectre_v1and spectre_v2 on Alpha.Tests on XP1000 (EV67/667MHz) and ES45 (EV68CB/1.25GHz) show themto be vulnerable to Meltdown and Spectre V1. In the case ofMeltdown I saw a 1 to 2% success rate in reading bytes on theXP1000 and 50 to 60% success rate on the ES45. (This compares to99.97% success reported for Intel CPUs.) Report EV6 and laterCPUs as vulnerable.Tests on PWS600au (EV56/600MHz) for Spectre V1 attack wereunsuccessful (though I did not try particularly hard) so mark EV4through to EV56 as not vulnerable.Signed-off-by: Michael Cree Signed-off-by: Matt Turner List of files: /linux-6.15/arch/alpha/kernel/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/arch/alpha/kernel/Makefile

85d0b3a5 - alpha: Reorganize rtc handling

Sat, 13 Jul 2013 22:49:45 +0000

alpha: Reorganize rtc handlingDiscontinue use of GENERIC_CMOS_UPDATE; rely on the RTC subsystem.The marvel platform requires that the rtc only be touched from theboot cpu. This had been partially implemented with hooks forget/set_rtc_time, but read/update_persistent_clock were not handled.Move the hooks from the machine_vec to a special rtc_class_ops struct.We had read_persistent_clock managing the epoch against which thertc hw is based, but this didn't apply to get_rtc_time or set_rtc_time.This resulted in incorrect values when hwclock(8) gets involved.Allow the epoch to be set from the kernel command-line, overridingthe autodetection, which is doomed to fail in 2020. Further, byimplementing the rtc ioctl function, we can expose this epoch touserland.Elide the alarm functions that RTC_DRV_CMOS implements. This washighly questionable on Alpha, since the interrupt is used by thesystem timer.Signed-off-by: Richard Henderson List of files: /linux-6.15/arch/alpha/kernel/Makefile

alpha: binfmt_aout fixThis fixes the problem introduced by commit 3bfacef412 (get rid ofspecial-casing the /sbin/loader on alpha): osf/1 ecoff binary segfaultswhen binfmt_aout built as module. That happens because aout binaryhandler gets on the top of the binfmt list due to late registration, andkernel attempts to execute the binary without preparatory work that mustbe done by binfmt_loader.Fixed by changing the registration order of the default binfmt handlersusing list_add_tail() and introducing insert_binfmt() function whichplaces new handler on the top of the binfmt list. This might be generallyuseful for installing arch-specific frontends for default handlers or justfor overriding them.Signed-off-by: Ivan Kokshaysky Cc: Al Viro Cc: Richard Henderson Signed-off-by: Linus Torvalds List of files: /linux-6.15/arch/alpha/kernel/Makefile

10a0ef39 - PCI/alpha: pci sysfs resources

Tue, 17 Feb 2009 10:46:53 +0000

PCI/alpha: pci sysfs resourcesThis closes http://bugzilla.kernel.org/show_bug.cgi?id=10893which is a showstopper for X development on alpha.The generic HAVE_PCI_MMAP code (drivers/pci-sysfs.c) is notvery useful since we have to deal with three different typesof MMIO address spaces: sparse and dense mappings for oldev4/ev5 machines and "normal" 1:1 MMIO space (bwx) for ev56 andlater.Also "write combine" mappings are meaningless on alpha - roughlyspeaking, alpha does write combining, IO reordering and otheroptimizations by default, unless user splits IO accesseswith memory barriers.I think the cleanest way to deal with resource files on alphais to convert the default no-op pci_create_resource_files() andpci_remove_resource_files() for !HAVE_PCI_MMAP case into __weakfunctions and override them with alpha specific ones.Another alpha hook is needed for "legacy_" resource filesto handle sparse addressing (pci_adjust_legacy_attr).With the "standard" resourceN files on ev56/ev6 libpciaccessworks "out of the box". Handling of resourceN_sparse/resourceN_densefiles on older machines obviously requires some userland work.Sparse/dense stuff has been tested on sx164 (pca56/pyxis, normallyuses bwx IO) with the kernel hacked into "cia compatible" mode.Signed-off-by: Ivan Kokshaysky Signed-off-by: Jesse Barnes List of files: /linux-6.15/arch/alpha/kernel/Makefile
