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.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Instead of developing separate blacklist matching for each transport class needing it, enhance the current list matching to permit multiple lists.

scsi: core: Add BLIST_NO_VPD_SIZE for some VDASD Some storage, such as AIX VDASD (virtual storage) and IBM 2076 (front end), fail as a result of commit c92a6b5d6335 ("scsi: core: Query VPD size before getting full page"). That commit changed getting SCSI VPD pages so that we now read just enough of the page to get the actual page size, then read the whole page in a second read. The problem is that the above mentioned hardware returns zero for the page size, because of a firmware error. In such cases, until the firmware is fixed, this new blacklist flag says to revert to the original method of reading the VPD pages, i.e. try to read a whole buffer's worth on the first try.

Since VPD data cannot be read from the device anyway we prevent the SCSI layer from even trying by blacklisting the device. This gets away the error and the system starts up normally.

To achieve this goal, we also need to: -- fail the REPORT_LUNS command for st_shasta because the firmware is known to not report all actual luns -- add an entry in scsi_devindo.c to force sequential lun scan (for st_shasta controllers) -- fail the REPORT_LUNS command for console device -- remove special handling of REPORT_LUNS command for st_yosemite, as there is no translation mapping now Signed-off-by: Ed Lin <ed.lin@promise.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>

SCSI: add 1024 max sectors black list flag This works around a issue with qnap iscsi targets not handling large IOs very well. The target returns: VPD INQUIRY: Block limits page (SBC) Maximum compare and write length: 1 blocks Optimal transfer length granularity: 1 blocks Maximum transfer length: 4294967295 blocks Optimal transfer length: 4294967295 blocks Maximum prefetch, xdread, xdwrite transfer length: 0 blocks Maximum unmap LBA count: 8388607 Maximum unmap block descriptor count: 1 Optimal unmap granularity: 16383 Unmap granularity alignment valid: 0 Unmap granularity alignment: 0 Maximum write same length: 0xffffffff blocks Maximum atomic transfer length: 0 Atomic alignment: 0 Atomic transfer length granularity: 0 and it is *sometimes* able to handle at least one IO of size up to 8 MB. We have seen in traces where it will sometimes work, but other times it looks like it fails and it looks like it returns failures if we send multiple large IOs sometimes. Also it looks like it can return 2 different errors. It will sometimes send iscsi reject errors indicating out of resources or it will send invalid cdb illegal requests check conditions. And then when it sends iscsi rejects it does not seem to handle retries when there are command sequence holes, so I could not just add code to try and gracefully handle that error code. The problem is that we do not have a good contact for the company, so we are not able to determine under what conditions it returns which error and why it sometimes works. So, this patch just adds a new black list flag to set targets like this to the old max safe sectors of 1024. The max_hw_sectors changes added in 3.19 caused this regression, so I also ccing stable.

This results in IO errors when handling large IOs. This patch just has us use the old 1024 default sectors for this target by adding it to the scsi blacklist. We do not have good contacs with this vendors, so I have not been able to try and fix on their side. I have posted this a long while back, but it was not merged. This version just fixes it up for merge/patch failures in the original version.

SCSI: fix bug in scsi_dev_info_list matching The "compatible" matching algorithm used for looking up old-style blacklist entries in a scsi_dev_info_list is buggy. The core of the algorithm looks like this: if (memcmp(devinfo->vendor, vendor, min(max, strlen(devinfo->vendor)))) /* not a match */ where max is the length of the device's vendor string after leading spaces have been removed but trailing spaces have not. Because of the min() computation, either entry could be a proper substring of the other and the code would still think that they match. In the case originally reported, the device's vendor and product strings were "Inateck " and " ". These matched against the following entry in the global device list: {"", "Scanner", "1.80", BLIST_NOLUN} because "" is a substring of "Inateck " and "" (the result of removing leading spaces from the device's product string) is a substring of "Scanner". The mistaken match prevented the system from scanning and finding the device's second Logical Unit. This patch fixes the problem by making two changes. First, the code for leading-space removal is hoisted out of the loop. (This means it will sometimes run unnecessarily, but since a large percentage of all lookups involve the "compatible" entries in global device list, this should be an overall improvement.) Second and more importantly, the patch removes trailing spaces and adds a check to verify that the two resulting strings are exactly the same length. This prevents matches where one entry is a proper substring of the other.

SCSI: fix new bug in scsi_dev_info_list string matching Commit b704f70ce200 ("SCSI: fix bug in scsi_dev_info_list matching") changed the way vendor- and model-string matching was carried out in the routine that looks up entries in a SCSI devinfo list. The new matching code failed to take into account the case of a maximum-length string; in such cases it could end up testing for a terminating '\0' byte beyond the end of the memory allocated to the string. This out-of-bounds bug was detected by UBSAN. I don't know if anybody has actually encountered this bug. The symptom would be that a device entry in the blacklist might not be matched properly if it contained an 8-character vendor name or a 16-character model name. Such entries certainly exist in scsi_static_device_list. This patch fixes the problem by adding a check for a maximum-length string before the '\0' test.

enhance device info matching for multiple tables The current scsi_devinfo.c matching routines use a single table for the global blacklist. However, we're developing a need to blacklist from specific transports too (notably some tape drives using SPI which don't respond well to high speed protocols). Instead of developing separate blacklist matching for each transport class needing it, enhance the current list matching to permit multiple lists.

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
